[0189] FIGS. 1-13 illustrate various embodiments an arc segment selectable exercise apparatus 10 that can be used in conjunction with a user interface 20 and associated processor 500 and sensor(s) or detector(s) D, FIG. 14-21, in accordance with the invention to enable a user to perform a variety of circuit or interval exercise routines or regimes in accordance with another aspect of the invention. The processor 500 is typically mounted within the housing 20h of the user interface but can alternatively be mounted remotely from the interface 20 and apparatus communicating wirelessly or via cables or wires with the visual display components of the user interface. A “processor,” as used herein, refers to electrical, electromechanical and electronic control apparati that can comprise a single box or multiple boxes (typically interconnected and communicating with each other) that contain(s) all of the separate electronic processing, memory and electrical or electronic signal generating components that are necessary or desirable for carrying out, creating, enabling and implementing the methods, functions and apparatuses described herein. Such electronic and electrical components include RAM, ROM and solid state or non-solid state memory devices, programs, algorithms, chips, chipsets, programs, processors, microprocessors, computers, PID controllers, voltage regulators, current regulators, circuit boards, motors, batteries and instructions for controlling any variable element discussed herein such as length of time, degree of electrical signal output and the like. For example a component of a processor, as that term is used herein, includes programs, data, algorithms, controllers and the like that perform functions such as storing and processing data, sending and receiving signals from sensors or detectors, or sending and receiving signals that instruct, and functions such as monitoring, alerting, initiating, executing or instructing an LCD or other visual display to display numbers, data or other information in a visually observable format by a human user.

[0190] FIGS. 14-21 illustrate a user interface component 20 of an apparatus according to the invention that serves to facilitate certain forms of cardiovascular training that have recently emerged: circuit training and interval training. Both workout techniques use a cycle of brief, high energy activity, followed by a rest period of similar length, as the fundamental building block for all workout routines. Interval training consists of a user or group of users repeatedly performing cycles of a single exercise, alternating between exercise and rest, while maintaining some form of timing scheme or plan. Circuit training consists of a user or group of users consecutively performing cycles of different exercises that each exercise different muscle groups, “circling” from one exercise station to the next while maintaining some form of timing scheme or plan. At any given step, different users with different body sizes and fitness levels will operate the same given device, making ease of use and speed of configuration important factors for any circuit training device.

[0191] As shown in FIGS. 12, 14 a detector D can be used to detect any one or more movements or properties of the apparatus 10 or the user or a component of the apparatus 10 such as the speed and time of rotation or other movement of the resistance assembly, in the case of the FIGS. 2-3A, 5-12 embodiments a fan 200. The speed detector can comprise an optical detector, a magnetic field detector, a Hall effect sensor, a potentiometer, one or more limit switches or any other detector that is capable of sensing a relevant measurable movement (rotational, translational or the like) of a mechanical element or component of a relevant mechanical element such as a wheel like fan wheel 200, an axle like crankshaft 32, 252h, a belt like belts 251, 253, a pulley like pulleys 250, 252, a foot support like supports 24a, 24b, a support pivot arm like arms 26a-26c or any other moving element of the apparatus, the rate of movement of which can be converted by an algorithm to the output results desired to be displayed on a visual display on the display area 20a of the user interface 20. The rate of movement or property detected by the detector D is generically designated as FR in FIGS. 12, 14 for purposes of explanation, it being understood that FR can alternatively comprise a value indicative of a movement other than the rotational speed of the fan wheel that can be used in an algorithm to generate a calculation of a result indicative the mechanical power or work input into the resistance assembly, a result such as power, energy, velocity, strides per minute, distance of movement by foot or by a bicycle of predetermined configuration.

[0192] As shown, the detector D sends a signal indicative of FR to the processor 500 which processes the signal according to a predetermined algorithm to calculate a value indicative of any desired aspect of the user's performance of exercise or the result of the user's exertion of force or energy in performance of the back and forth movement of the foot pedals 24a, 24b of the apparatuses shown in FIGS. 1-13. In the examples of FIGS. 14-21, the algorithm included in the processor is designed to use the variable input of FR to calculate for example, the number of watts of power exerted by the user, the number of meters that the user would have travelled if riding a bicycle having a preselected configuration while generating such power as calculated from FR and the number of strides per minute that the user would have achieved exerting the power or force calculated by the algorithm based on the FR input as a variable to the algorithm. Where the rotational speed of the fan wheel 200 is sensed and used in an algorithm, other values or parameters peculiar to the wheel 200, such as the number, size and shape of fan blades, are included in the algorithm in order to generate a value for the moment of inertia of fan wheel 200 (alternatively, the value for the moment of inertia may be provided to the algorithm in advance, in the form of a static variable) the moment of inertia being used to calculate the desired result such as watts, power, energy, work, distance travelled, number of strides and the like. As can be readily imagined, one or more additional or different detectors could alternatively be used to sense a rotational or translational movement and send a signal to processor 500 that is indicative of the speed or velocity of such movement such as of a shaft 32, 252h, a belt 251, 253, a pulley 250, 252, a foot support 24a, 24b, a support pivot arm 26a-26d and, a signal indicative of such movements could be used in an appropriate algorithm to generate and display one or more visual results indicative of watts, energy or power exerted by the user, number of meters that the user would have travelled if riding a bicycle, number of strides per minute and the like.

[0193] The aforementioned algorithm can include instructions that carry out a mathematical compensation that accounts for the effects of air temperature and pressure dependencies in the determination of the mechanical power expressed by the rotation of fan wheel 200. While the derivation of a power figure based on a measurement of the angular, or rotational, velocity of a spinning fan is generally known in the art, such calculations assume a constant value for the density of the surrounding air. Pressure and temperature sensors (not shown) can provide additional inputs to the processor 500, allowing a real-time and accurate measurement of air density to be made and used in the algorithm that generates the desired output results for display on the user interface. For a gas, such as air, the relationship between the pressure (P), volume (V), and temperature (T) exhibits a known and mathematically predictable relationship, generally approximated via the Ideal Gas Law. It may be further derived that density is directly proportional to the pressure of the gas, and inversely proportional to the temperature of the gas. Therefore, the use of temperature and pressure sensor readings and inputs to processor 500 can enable a calculation of air density for purposes of calculating a more accurate value for the power generated by rotation of fan blade 200.

[0194] FIGS. 1-13 illustrate a typical back and forth stride-like foot and leg driven apparatus that provides a user-exerciser with a low impact workout yet offers the potential for an intensive cardiovascular workout by eliminating the unnatural motion and awkward foot alignments typical of many stair-climbing and elliptical training devices. The apparatus 10 provides one or more foot supports 24a, 24b movable along an arcuate path defined around a point P of rotation. The arcuate path is selectively divisible into machine defined, user selectable arc segments. The apparatus 10 includes a frame 16a, 16b, 16c, 16d, a frame linkage 26a, 26b, 26c, 26d movably engaged with the frame, one or more foot supports 24a, 24b movably engaged with the frame linkage, a crank 40a, 40b movably engaged with the frame, and in the embodiments shown, an arc segment selection or adjustment mechanism that pivots the location of the crank assembly with respect to the frame, and a drive linkage 28a, 28b movably engaging the frame linkage.

[0195] In alternative embodiments (not shown), the arc segment selection device or assembly can comprise an assembly of mechanical components that enable the user to select an arc segment without pivoting or moving the crank or resistance assembly relative to the frame.

[0196] FIGS. 14-21 illustrate a typical embodiment of a user interface 20 that is mounted and arranged on the frame 16 of the apparatus 10 such that a visual display and manually actuatable or engageable interface area 20a of the interface 20 is both readily manually accessible by a user and readily visually observable by a user when a user is standing on a foot support 24a, 24b in particular when standing upright on a foot support.

[0197] FIG. 1-3, 4-11 are view of various embodiments of an arc segment selectable exercise device that includes a frame 10 having a front region 12, a rear user disposition region 14, frame legs 16a, 16b, 16c and 16d, and frame upper supports 18a, 18b, 18c, and 18d. Upper supports 18c and 18d comprise the upper links of a pair of four bar linkages and part of the arcuate portion of the frame, terminate in legs 16c and 16b respectively and are an integral part of frame 10. A display/control panel 20 and hand grips 22a and 22b are secured to the upper supports 18a and 18b.

[0198] Foot supports 24a and 24b are sized to receive the foot of a user. Foot supports 24a and 24b are movably connected to, and supported by, forward linkages or legs 26a and 26b, and rear linkages 26c and 26d. Linkages 26a-26d are movably connected to the rear region 14 of frame 10 by upper supports or links 18d and 18c. Although the device is shown with opposing pairs of linkages supporting each foot support, other embodiments are contemplated having fewer or more linkages supporting and controlling the range and path of motion of foot supports 24a and 24b associated with the linkage(s).

[0199] The foot supports 24a and 24b approximate a shoed human foot in size and shape. They can include a non-skid surface and be bounded by one or more low lips to help a shoe remain in place on the foot supports during use. Alternately, straps may maintain each foot within the foot support to further retain the user's foot in place during use. However, as used herein, a “foot support” can also encompass any designated support such as a pedal, a pad, a toe clip, or other foot/toe/leg and device interface structure as is known in the art.

[0200] The forward linkages or legs 26a and 26b are movably connected to drive linkages 28a and 28b; and the drive linkages are in turn connected to the resistance mechanism (illustrated in FIGS. 2A, 3 and 4 and described below) concealed by a housing 30. In other embodiments, the drive linkages 28a and 28b can be connected directly to the foot supports 24a and 24b. Additionally, foot supports can be on or integral to either the forward linkages or to the one or more linkages joined to the frame.

[0201] As illustrated in FIGS. 1-3, 4-11, representative movable connectors 31a, 31b, 31c, and 31d include pivot assemblies, as known in the art, that provide smooth and easy relative rotation or reciprocal motion by elements joined by the pivot assemblies. Movable connectors 31b and 31d rotatably couple forward linkages or legs 26b and 26a, respectively, to upper supports or links 18c and 18d. Movable connectors 31c and 31a rotatably couple rear linkages 26c and 26d, respectively, to upper supports or links 18c and 18d. Other connection assemblies that permit similar motion are contemplated by the invention. The movable connectors allow for a smooth and controlled swinging of foot supports 24a and 24b in an arcuate path.

[0202] FIG. 2 is a front perspective view of one specific embodiment of an apparatus 10 as shown in FIG. 1 illustrating the elements described above from a different angle and showing in addition a manually engageable and actuatable screwable arc segment selectable mechanism 225 that is mechanically interconnected between the frame component 17 and the pivotable resistance assembly mounting bracket or arm 38. This illustration shows the device from the front region 12 perspective. Once again it can be seen that foot supports 24a and 24b are suspended from their respective linkages. Drive linkages 28a and 28b (not shown in FIG. 2) are coupled at their first ends to the substantial mid-point of front linkages or legs 26a and 26b, respectively. Drive linkages 28a and 28b are coupled at their second ends to a crank assembly 40a, 40b, 40c, 40d contained within housing 30, which contains the resistance assembly shown in FIG. 4 and described in greater detail below.

[0203] As shown in FIGS. 2, 3, 3A, the screw 225 has a crank or wheel handle 227 connected to a proximal end of the screw 225 that is mounted so as to be readily manually accessible and engageable by a user located in the user disposition region 14 of the apparatus 10. The handle is readily rotatable or turnable by hand by a typical human user so as enable the user to readily effect rotation T of the screw 225 to any desired degree of rotation quickly and immediately upon manual engagement. The screw 225 is screwably engaged at distal position with a screw receiving bracket or nut 38a, FIG. 3, that is attached to the mounting bracket or arm 38 that is mounted to the frame 10 such that when the screw 225 is rotated either counterclockwise or clockwise by a user by a selected degree SR, the screw 225 is translationally moved a corresponding selected distance FBD, FIGS. 3, 3A, relative to the frame 10 on manual turning of the screw 225 by the selectable rotational degree SR by the user. The screw 225 is interconnected to the foot support such that translational movement of the screw the selectable distance FBD fixes or limits travel of the foot support to a corresponding one of the plurality of different arc segments. The bracket or arm 38 will pivot back and forth FB and move a corresponding selectable distance depending on the degree of rotation T and length of translational movement FBD of the screw 225. In the same manner as described below with reference to the manually drivable piston embodiments of FIGS. 5-8 the degree of such pivoting back and forth FB of bracket or arm 38 as determined by the degree and direction of rotation T of screw 225 enables the user to selectively change the identity of the particular arc segment through which the foot pedals will travel when the pedals are driven between a forwardmost upward and rearwardmost downward position. Depending on the particular arc segment chosen by the user, the degree of incline of the foot pedals and thus the degree of difficulty of driving the foot pedals 24a, 24b back and forth will vary. As shown in FIG. 3 the bracket or arm 38 is disposed in a first generally vertical disposition similar to the disposition shown in FIG. 5 where the horizontal component of the force F required is FH1 and vertical component of the force F required to move the foot pedals is FV1. As shown in FIG. 3A, the screw has been turned T such that the bracket or arm 38 is now disposed at an angle A relative to the position of FIG. 3 (similar to the difference in arm and foot pedal positions between FIG. 6 and FIG. 5) and the horizontal FH2 and FV2 components of force required to drive the foot pedals 24a, 24b through the new arc segment associated with the new pivoted position A of the bracket or arm 38 has changed relative to the position of the arm in FIG. 3 and thus degree of difficulty of the force F needed to perform an exercise cycle has been selectively changed by the user.

[0204] In each of the embodiments described herein the arc segment selection device is manually actuatable by the user to exert a selectable amount of manual force on the selection device that operates to selectively position, vary or adjust the resistance assembly in or to any one of a plurality of predetermined fixed mechanical positions that vary according to the selectable amount of manual force exerted by the user on the selection device. Such user force or energy exerted, manually driven arc segment selection systems are preferred so that a user can immediately without delay change an arc segment during the course of performing a circuit of different exercises in rapid sequential succession using different machines or otherwise performing different exercises that exercise different muscle groups at different periods of time during the course of the entire circuit of sequential different exercises.

[0205] In alternative embodiments, the selection device can be controllably driven by a motor or other electrically or electronically powered device rather than via exertion of a user's manual energy or force.

[0206] As shown in FIGS. 3, 3A, 5-9, 11-13, the resistance assembly can comprise a rotatably drivable R wheel 200 having fan blades 210 having surfaces 210a that engage against ambient air when the wheel is driven R. The degree of resistance to rotation R of the finned 210 wheel 200 increases or varies exponentially or non-linearly with the degree of speed of rotation R of the finned 210 wheel 200. Typically the degree of resistance RES, FIGS. 3A, 12 to rotation R of a fan or finned wheel 200 increases or varies by a cube or cubed factor of or with the degree of speed of rotation R. Other resistance mechanisms other than a finned 210 wheel 200 such as an Eddy current controlled brake mechanism can be employed that increase, decrease or vary in degree of resistance relative to the force F exerted by the user in a non-linear, geometric or exponential manner or relationship.

[0207] In the embodiment shown in FIGS. 2, 3, 3A, 5-8, 11 the axis of the resistance wheel 200 is connected directly to the axle 32 of a crankshaft such that the wheel 200 rotates R at the same speed of rotation as the crankshaft. Crank arms 40a and 40b are secured to each end of the crankshaft 32 and are movably coupled to the drive linkages 28a and 28b, respectively. As linkages 28a, 28b are driven back and forth as a result of back and forth foot driven movement of pedals 24a, 24b, crank arms 40a, 40b are rotatably R driven which in turn via their interconnection to shaft 32 rotatably R drive shaft 32 around its axis.

[0208] In alternative embodiments shown in FIGS. 9, 10, 12, 13 intermediate drive pulleys or wheels 250, 252 and associated belts 251, 253 are typically employed whereby the hub 200h of wheel 200 is not directly connected to and does not rotate in unison with shaft 32 but instead is rotatably driven at a higher rate XR than shaft 32 which is driven at rotation rate R. As shown, in FIGS. 12, 13 the crankshaft 32 is directly connected to the hub 250a of intermediate drive pulley 250 driving pulley at rate R. Drive pulley 250 in turn drives a second intermediate drive pulley or wheel 252 via belt 251 at a higher rotational rate of YR by way of an intermediate hub 252h that has a smaller radius than the radius of both of pulleys 250, 252. Intermediate drive pulley 252 in turn drives fan wheel 200 via belt 253 at an even higher rotational rate of XR by way of another intermediate hub 200hh to wheel 200 that has a smaller radius than radius of both pulleys 252 and 250. In a typical embodiment the ratio of XR to R is between about 10:1 and 20:1, most typically between about 13:1 and 15:1.

[0209] Rotation of the resistance wheel 200 as described herein whether the wheel 200 rotates in unison with the shaft 32 or at a higher rotational rate creates a resistance to the force F exerted by the user such that the degree of force resistance RES created by the wheel 200 varies exponentially or geometrically with the rate of rotation R or the amount of force exerted by the user on account the interaction of the surface 210a of the fan blades 210 that are mounted to the axle 220 of the wheel 200 with air. The faster that wheel 200 rotates the amount of air resistance against surfaces 210a of blades 210 increases exponentially or geometrically. Similarly, the rate of rotation generally varies non-linearly (exponentially or geometrically), with the degree of speed, velocity, force, work or power exerted by the user on the foot supports 24a, 24b or resistance assembly 200 et al. Typically the degree of resistance to rotation R of a fan wheel 200 increases or varies by a cube or cubed factor of or with the degree of speed of rotation of the wheel.

[0210] Top bearings 36a and 36b receiving the axle or crankshaft 32 are secured to a pivotable mounting bracket or arm 38 such that as pivotable bracket or arm 38 is pivoted forwardly and rearwardly, shaft 32 and its associated wheel 200 is pivoted forwardly and backwardly together with bracket or arm 38.

[0211] As shown in FIGS. 2-8 in order to drive the foot pedals through any selected arc segment, the user must exert a force F on foot pedals 24a, 24b that has a horizontal (or forward-rearward) component FH, FH1, FH2 and a vertical (or upward-downward) component FV, FV1, FV2. The degree of incline of the arc segment that the foot supports must travel through is determined by and will vary with the precise degree of the forward to rearward pivot position of bracket or arm 38 As shown in FIGS. 3-8 the mounting bracket or arm 38 pivots around the axis AA of bottom bearings 46a and 46b so as to be rotatable forwardly and rearwardly FB.

[0212] FIG. 4 is a side view of an exercise apparatus 10. In this view, the foot supports 24a and 24b, forward linkages or legs 26a, 26b and rear linkages or legs 26c, 26d are presented from a perspective that allows ready visualization of the path that foot supports 24a and 24b, and thus a user's feet, will traverse as the foot supports move fore and aft while suspended from the forward and rear linkages. It will be noted that as foot supports 24a and 24b move fore and aft, the forward and aft limit of motion is not unbounded. Rather, the range of motion is defined by the length of the crank arms 40a and 40b (shown in FIG. 4), which provide an appropriate stride length. Further, because the foot supports 24a and 24b are pivotally connected to, and swing with, the forward linkages 26a, 26b and rear linkages 26c, 26d, the foot supports travel a curved or arcuate path, and not an elliptical path, to provide more favorable biomechanics.

[0213] The motion path for the foot supports 24a and 24b can be selectively adjusted by adjusting the pivot position of mounting bracket or arm 38. As described above, the mounting 38 is pivotally mounted to the frame member 48 and pivots fore and aft upon selective manual actuation of a mechanical adjustment mechanism. As is evident by reference to the Figures, pivoting the mounting 38 forward moves the components such as wheel 200 secured directly or indirectly thereto forwardly. Likewise, pivoting the mounting 38 rearward causes the components secured directly or indirectly thereto to move rearward. This selective positioning FB of bracket or arm 38 causes the arcuate segment or motion path of the foot supports 24a and 24b to move to a different location along an arcuate path around a point of rotation “p”, shown between pivot assemblies 31b and 31c, at a distance established by the length of the forward and rear linkages or legs 26a, 26b, 26c and 26d. Thus, the specific location on the master arc or arc segment (“the motion path”) is user selectable to increase or decrease stride angle and location from a number of user selectable points, or arc segments, defined around the point of rotation.

[0214] In operation, a user approaches the device from the rear region 14, grasps the hand grips 22a and 22b, and places a foot on each of the foot supports 24a and 24b. The user's feet and legs begin to move fore and aft in a comfortable stride. The user selects an exercise program or manually adjusts the device by imputing commands via the display/control panel 20. Also, in response to command input, the mounting 38 is moved fore or aft. As shown, when the mounting 38 moves forward, the motion path of the foot supports is on a more inclined or vertical defined arc segment. To discontinue use of the device, a user simply stops striding, thereby causing the movement of the device to stop, and dismounts from the foot supports.

[0215] FIG. 4 illustrates one of the four bar linkage support mechanisms in a forwardmost, 26a′, 26d′ and a rearward 26a, 26d position along the pivot stroke of the four bar linkage. The four bar linkage has opposing pivot widths (or opposing pivot link, 18c/24b, 18d/24a widths), W′ and W″, and opposing pivot lengths (or opposing pivot link, 26a/26d, 26b/26c lengths), L′ and L″ that form the functional four bar linkage for purposes of pivotably mounting/supporting the foot pedal 24a from an upper portion 18d (or foot pedal 24b from upper portion 18c) of the overhead support arm or leg, 16b, 16c, of the frame. The foot pedals 24a, 24b themselves comprise a structural portion or the whole of the lower pivot link of the four bar linkages in the embodiments shown in FIGS. 1-10. The distances between the width pivot points 31a and 31d, W′ and between the width pivot points 31e and 31f, W″ are preferably equal or substantially equal. And, the distances between the length pivot points 31d and 31e, L′ and between the length pivot points 31a and 31f, L″ are also preferably equal or substantially equal such that the difference between angles A1 and A2, i.e. the degree of rotation or pivot of the foot pedal 24a from back to front and front to back along the arcuate path of translation of the foot pedal from front to back and vice versa is less than about 3 degrees, typically less than about 2.5 degrees. The foot pedals have a foot sole receiving upper surface that defines a generally planar orientation or plane in which the sole of the foot of the user is maintained when standing on a foot pedal. Angle A1 is the angle between the foot sole orientation plane PP1 in which the foot sole surface resides at the backwardmost end of the front to back path of translation and a fixed selected reference plane RP. Angle A2 is the angle between the sole orientation plane PP2 in which the foot sole surface resides at the forwardmost end of the front to back path of translation and the fixed selected reference plane RP. In this preferred embodiment, the difference between angles A1 and A2, at any point/position along the back to front/front to back path of translation of the food pedal 26a is preferably less than about 3 degrees (typically less than about 2.5 degrees), i.e. the plane in which the foot sole surface of the pedal 24a resides does not rotate or pivot more than about 3 degrees at any time during movement through the arcuate path of translation.

[0216] As can be readily seen from FIGS. 1-10, the foot pedals always travel in the same overall or master arcuate or other configuration of path of travel from front to rear and from rear to front. The master arcuate path of travel J, FIG. 5, that the pedals 24a, b may travel in remains the same regardless of what degree of pivot the bracket or arm 38 is positioned in. Pivoting the support bracket or arm 38 to different pivot positions only changes the arc “segment” (e.g. segment AP, FIG. 5, or segment AP′, FIG. 6, or segment AP″, FIG. 8) through which the pedals may travel from rearwardmost to forwardmost positions but does not change the overall or master path of arcuate travel J. The master arcuate path of travel J is defined by the machine or apparatus itself, i.e. by the mounting, positioning, lengths and widths of the links 18c, d, 24a, b and 26a-d. The user may select a segment of the overall machine defined arcuate path of foot pedal travel J depending on the degree of pivoting of bracket or arm 38 that the user selects for any given exercise session. As described below each segment selected will have a different degree of incline, e.g. H1 for segment AP and H2 for segment AP′.

[0217] In an alternative embodiment as shown in FIGS. 5-8 mounting bracket or arm 38 can be manually pivoted FB via extension or contraction of a mechanical arm or piston 230 that acts as a tilt actuator to pivot the mounting bracket or arm 38 forwardly or backwardly as desired by the user. In the FIGS. 5-8 embodiment, the arc segment selection device typically comprises a fluid driven piston 230 mounted in a fluid sealed cylinder having a drive axis PA, the piston 230 being manually drivable by application of the manual force applied by the user to drive fluid contained within the cylinder via push or turn mechanism 230a to translationally drive the piston a selectable distance PT from its retracted position along the drive axis PA of the cylinder to a selectable one of a plurality of translation positions that correspond to one of the plurality of different arc segments AP, AP′. As can be readily imagined, arm or piston 230 is manually actuatable by the user such as by the user's exerting a selectable degree of manual force by manually actuating a mechanical pumping or screwing mechanism 230a that mechanically causes the arm or piston 230 to extend or contract to a desired degree of translation distance PT that varies with the degree of mechanical force or energy exerted by the user on mechanism 230a and in turn mechanically pivots FB the bracket or arm 38 to a desired degree. Alternatively the piston 230 could be screwably engaged within the cylinder with the manual mechanism 230 and be movable translationally in the same or similar manner to the screw 225 embodiment where the user manually exerts force to turn the mechanism 230a that through worm gear or nut screwably cause the piston to translate. As shown, the resistance mechanism 200 pivots forwardly and backwardly FB about the pivot axis A of bracket or arm 38 which is orthogonal to the longitudinal axis of the frame 10. Both of the pedals 24a and 24b are synchronized together by the motion of crankshaft 32.

[0218] FIGS. 5 and 6 more clearly illustrate the previously described selectability of an arc segment when the mounting member 38 and its associated wheel 200 or other resistance device is/are pivoted or tilted from one orientation to another. As shown in FIG. 5, the pivotable mounting bracket or arm 38 is positioned with its longitudinal axis X arranged in about a vertical orientation. In this orientation, the maximum difference in height or incline H1 between the rearwardmost position 24b′ of the foot pedal 24b and forwardmost position 24b″ of the foot pedal 24b is less than the maximum difference in height or incline H2 of FIG. 8 where the axis of the mounting member 38 and its associated components 30 have been tilted or pivoted forwardly by an angle A from the position of FIG. 5. As shown, the arcuate path AP of the pedals 24b in FIG. 5, going from position 24b′ to 24b″, is less steep or upwardly inclined than the arcuate path AP′ of the pedals going from position 24b′″ to 24b″″ in FIG. 6. Thus, as shown, the user can select the degree of arc of travel of the pedals by selecting the position of tilt of assembly 30 to which the linkage bars 28b are attached.

[0219] As also shown in FIGS. 5 and 6 the pedals travel along the same selected arcuate segment path AP or AP′ from front to rear and from rear to front one the pivot position of bracket or arm 38 is selected.

[0220] FIGS. 7 and 8 show an embodiment where a pair of pivoting upper body input arms 100a, 100b are provided that the user can manually grasp by hand at an upper region such as handles 106a, 106b, the handles 106a, b being a rigidly connected extension of arms 100a, 100b respectively and moving/pivoting together with the arms forward or backward. The handles 106a, 106b and arms 100a, 100b are pivotably interconnected to both the frame and to the pedals. As shown the handles 106a, 106b and arms 100a, 100b are pivotably interconnected to the frame via a cross bar member 500, the bottom ends of the arms being freely pivotably mounted via pin/aperture joints 104a, 104b at their bottom ends, the joints being attached to bar support member 500 at appropriate distances from each other along the length of bar support 500. Arm linkage members 102a, 102b, are pivotably attached at one end to the arms at joints 108a, 108b which allow the linkage members to rotate/pivot on and with respect to the arms. Linkage members 102a, 102b are also pivotably attached at another end to some component of the arcuate path traveling assembly of foot pedal, and four bar linkage supports 26. As shown in FIGS. 9, 10 an end of the linkages 102a, 102b distal from the arm connection point are pivotably attached to the forward longitudinal four bar linkage members 26d, 26a respectively via joints 110a, 110b that allow the linkage members to rotate around the axes of the joints, the joints interconnecting the linkage members 102a, b and the longitudinal four bar linkage members 26d, a.

[0221] As shown in FIGS. 7, 8 as the foot pedal assemblies 24, 26 travel along the arcuate path AP″ from either front to back or from back to front, the handles 106 and arms 100 follow the front to back movement of the pedals with a pivoting front to back or back to front movement. That is, when the right pedal 24a moves forwardly the right handle 106a and arm 100a pivot or move forwardly; when the right pedal 24a moves backwardly the right handle 106a and arm 100a pivot or move rearwardly; when the left pedal 24b moves forwardly the handle 106b and arm 100b pivot or move forwardly; when the left pedal 24b moves rearwardly the handle 106b and arm 100b pivot or move rearwardly. Such following motion is shown for example with reference to four bar linkage arm 26d in three sequential front to back positions 26d1, d2 and d3 which correspond respectively to arm 100a positions, 100a1, a2, a3. The degree of front to back pivoting of the arms 100a, b can be predetermined at least by selective positioning of the pivot joints 108a, 108b, 110a, 110b, selective positioning of cross bar 500 and selection of the lengths of linkage arms 102a, 102b.

[0222] In the FIGS. 7, 8 embodiments, the user can reduce or transfer the amount of energy or power required by the user's legs and/or feet to cause the foot pedals to travel along the arcuate path AP″ from back to front by pushing forwardly on the upper end of the arms 102a, 102b during the back to front pedal movement. And, the user can increase the speed of forward movement by such pushing; or reduce the speed and increase the power or energy required by the legs to effect forward movement by pulling. Conversely the user can reduce or transfer the amount of power or energy required to cause the pedals to move from front to back by pulling backwardly on the upper end of the arms. And, the user can increase the speed of rearward movement by such pulling or reduce the speed by pushing; or reduce the speed and increase the power or energy required by the legs to effect rearward movement by pushing.

[0223] The four bar linkage foot assemblies, 24a, 26a, d, 18d and 24b, 26c, b, 18c that are pivotably linked via the linkages 102a, 102b to the pivotably mounted arms 100a, 100b can be configured to enable the foot pedal and the plane in which the sole of the foot is mounted to either not rotate or to rotate/pivot to any desired degree during front to back movement by selecting the lengths L′ and L″ and widths W′ and W″, FIG. 4 appropriately to cause the desired degree of rotation/pivoting. These four bar linkage assemblies also, via the above described linkages to the arms 100a, b, cause the arms to travel along the same path of pivot from front to back and back to front.

[0224] In the embodiment shown in FIGS. 4-8, the linkages 28a, 28a′, 28a″, 28a′″ and 28b, 28b′, 28b″, 28b′″ are interconnected to the wheel 200 via the four bar linkage and the linkages 28a, 28b at opposing 180 degree circle positions 40c and 40d from the center of rotation of the crank arms 40a, b and/or shaft 32, i.e. the linkages are connected at maximum forward and maximum rearward drive positions respectively. This 180 degree opposing interconnection causes the right 24b, 24b′, 24b″, 24b′″ and left 24a, 24a′, 24a″ and 34a′″ foot pedals to always travel in opposite back and forth translational directions, i.e. when the right pedal is traveling forward the left pedal is traveling backwards and vice versa. Similarly, the pivotably mounted arms 100a and 100b are interconnected to the bracket or arm 38 and wheel 200 via the four bar linkage, the links 28a, 28b and the links 102a, 102b such that when the right arm is moving forward the left arm is moving backward and vice versa. As shown in FIGS. 7, 8 the arms 100a, 100b travel forwardly or backwardly together with their associated foot pedals 28a and 28b respectively.

[0225] In any event, the left and right side pedals 24a, b and input arms 100a, b are linked to the resistance 200 or drive assembly 28a, 28b, 40a, 40b, 32 such that when the left side components (i.e. left pedal and associated input arm) are traveling forward the right side components (i.e. right pedal associated input arm) are traveling backward for at least the majority of the travel path and vice versa.

[0226] The upper body input arms 100a, b are interconnected or interlinked to the same pivotable mounting member 38 as described above via the links 102a, b, four bar linkage members 26a, b and links 28a, b as shown in FIGS. 7, 8. In the same manner as forward or backward pivoting of the mounting member 38 changes the degree of incline and/or path of travel of foot pedals 24a, b as described above with reference to FIGS. 5, 6, a forward or backward pivoting of the mounting member 38 also changes the degree of back to front pivoting and/or the degree of path of travel of arms 100a, b. Thus, in the same manner as the user is able to select the degree of incline of the path of travel of the foot pedals, e.g. arc path segment AP versus arc path segment AP′ as shown in FIGS. 5, 6 and also described above with regard to mount member 38 enabling the user to select the degree of arc segment stride length and angle/incline, the user is able to select the degree of back to front/front to back pivot stroke or travel path of input arms, 100a, b, by adjusting the front to back pivot position FB of the center of rotation of rotation connection/interconnection points 40c and 40d.

[0227] The input arms 100a, b are linked to the foot pedals 24a, b in a manner that causes an input arm (e.g. 100a) to move forwardly as its associated foot pedal (24a) moves forwardly and upwardly, or conversely that causes an input arm to move backwardly as its associated foot pedal moves backwardly and downwardly along the user selected arc segment.

[0228] FIGS. 9-10 illustrate an alternative manually actuatable mechanism for mechanically adjusting FB the position of bracket or arm 38 and thus the selection of a particular arc segment. In the FIGS. 9-10 embodiment, the manually adjustable element comprises a U-shaped handle assembly 300 that is attached to pivoting bracket or arm 38. The handle assembly includes a locking arm 307 that is spring load biased in a downward DN direction such that the distal end tooth 308 is biased into being received within a selected one of forward to back FB fixed position slots 306a, 306b, 306c, etc that are provided within fixedly mounted arm 306. Pivotable movement of the handle assembly 300 in the FB direction pivots the bracket or arm 38 and any associated resistance mechanism such as fan 200 in unison around pivot point AA thus changing the arc segment depending on the degree of movement of the handle assembly 300 in the FB direction. As shown the handle assembly 300 can be pivoted around axis AA between a plurality of preselected fixed back and forth positions, 306a, 306b, 306c, etc depending on the number and precise location of slots 306a, 306b, 306c, etc that are provided within the upper surface of positioning bar 306 that is fixedly attached or interconnected to the frame 16a-16d, 18a-18d. Back forth positioning FB of the handle assembly 300 and its fixedly interconnected bracket or arm 38 between preselected fixed positions 306a, 306b, 306c can be achieved by the user's manually grabbing the upper handle element 304 and pivoting FB the handle assembly 300 around pivot axis AA by any selectable degree. The handle assembly 300 in combination with its fixedly interconnected arm 38 effectively comprise pivotable lever that is pivotably mounted to the frame around pivot axis AA and is interconnected to the foot support, the lever having a proximal handle 304 that is readily manually accessible by a user standing on a foot support such that the user can selectively pivot the lever 38, 300 a selected arcuate degree FB. Manual pivoting of the lever 38, 300 the selected arcuate degree thus limits travel of the foot support through a corresponding selected one of the plurality of different arc segments. In operation, when the user manually engages the handle 304, the user can simultaneously squeeze upwardly UP, FIG. 10 on the underside surface 302a of spring loaded trigger 302 to cause the trigger 302 and its interconnected arm 307 that is slidably mounted within an arm housing 300h to move upwardly UP, FIG. 10 toward the handle 304 such that the distal end of the arm 307 which comprises a tooth 308 complementary in shape to the slots 306a, 306b, 306c, etc becomes disengaged and is withdrawn out of whichever slot 306a, 306b, 306c, etc that the tooth is locked into by the downward DN spring load that is exerted on trigger 302 and arm 307 by the spring mechanism (not shown). As in the FIGS. 2-3, 5-8 embodiments, in such a FIG. 9-10 embodiment therefore, depending on the degree or amount of manual force exerted by the user in the FB′ direction on handle assembly 300, an arc segment AP, AP′ having a selected and different degree of incline and requiring a selected and different degree of force F to move horizontally FH1, FH2 and vertically FV1, FV2 can be manually selected by the user by the exertion of a selected amount of manual force on the arc segment selection device 300.

[0229] FIGS. 11-12 illustrate another alternative manually actuatable mechanism for mechanically adjusting the position FB of bracket or arm 38 and thus the selection of a particular arc segment. In the FIGS. 11-12 embodiment, the manually adjustable element comprises an elongated cylindrical handle assembly 400 comprising a tube or tubular handle 404 pivotably mounted to the frame 16a-16b, 18a-18b, for back and forth FB′ movement, a rod or trigger 406 slidably mounted within the handle 404 rod that is spring load biased in an upward UP direction by a spring (not shown), a bracket 402 with upwardly extending slots 402a, 402b, 402c and a lever assembly 404 that is pivotably interconnected between the handle 404 and the resistance mounting bracket or arm 38. The tube or tubular handle 400 effectively comprises a pivotable lever that is pivotably mounted to the frame 10 and interconnected to the foot support. The lever 400 is pivotably mounted to the frame 16b, 18d, 10 and pivots around axis AAA. The lever 400 has a proximal handle portion 404 that is readily manually accessible by a user while standing on a foot support 24a, 24b such that the user can selectively pivot FB the lever 400 a selected arcuate degree FB, the pivoting of the lever the selected arcuate degree limiting travel of the foot support through a corresponding selected one of the plurality of different arc segments. The handle or lever 400 is manually pivotable back and forth FB′ between selectable fixed positions corresponding to slots 402a, 402b, 402c. As shown the lever 400 is interconnected to lever arm 38 via lever linkages 408. A user can adjust the back and forth FB′ position of the lever 400 and its pivotally interconnected bracket or arm 38 between preselected back and forth fixed positions that correspond to slots 402a, 402b, 402c by the user's manually grabbing the handle 404 and simultaneously pushing downwardly DN, FIG. 12 on the top surface 406a of spring loaded trigger 406 to cause the trigger 406 slidably mounted within handle 404 to move downwardly DN such that a pin 406b that projects laterally from the sliding rod or trigger 406 is disengaged from within whichever of slots 402a, 402b, 402c that the pin 406b is received within. Once the trigger 406 is manually actuated downwardly DN a distance sufficient to release pin 406a from a slot 402a, 402b, 402c, the user can manually exert a selected amount of back and forth FB′ directed force that in turn pivots the mounting bracket or arm 38 and its associated resistance assembly to a selected back and forth FB position. Once a desired back and forth FB′ position is reached, the user releases downward force on the trigger surface 406a, the trigger 406 is urged upward UP and the locking pin 406b is allowed to be received into a selected one of the slots 402a, 402b, 402c thus locking the handle assembly 400 and mounting arm into a selected forward to back FB position. As in the FIGS. 2-3, 5-8 embodiments, in such a FIG. 11-12 embodiment, therefore, depending on the degree or amount of manual force exerted by the user in the FB′ direction on handle assembly 400, an arc segment AP, AP′ having a selected and different degree of incline and requiring a selected and different degree of force F to move horizontally FH1, FH2 and vertically FV1, FV2 can be manually selected by the user by the exertion of a selected amount of manual force on the arc segment selection device 400.

[0230] Although the wheel 200 with fan blades 210 is one preferred resistance assembly, other resistance devices that create resistance that varies either linearly or non-linearly with the degree of speed, velocity, force F, work or energy exerted by the user on the foot supports or resistance assembly are known to those skilled in the art and can be interconnected to the foot pedals 24a, 24b.

[0231] FIG. 14 is a detailed view of the interface console region 20 of the present invention, consisting of an LCD type visual display 21 a and user operated panel of manually actuatable or engageable push-buttons 21b. By its nature, the LCD type visual display is capable of executing multiple different interfaces or information-carrying images, described in detail below. The panel of push-buttons remains fixed, with each button achieving a specified function.

[0232] Button 128, labeled “CIRCUIT|INTERVAL” permits the user to quickly and easily select the desired mode of operation—accordingly, he or she simply depresses the top portion 128a to enter Circuit Training Mode, and depresses the lower portion 128b to enter Interval Training Mode. Up and down arrow keys, 130a and 130b respectively, allow the user to toggle between consecutive numerical values when setting inputs such as desired time or desired number of intervals. Button 124, labeled “GO ENTER”, functions as a confirmation tool, allowing the user to begin the workout routine as well as approve input values or any other user-system dialogues and interactions. Button 126, labeled “STOP REVIEW”, serves the opposite purpose, allowing the user to terminate the workout routine and/or enter review mode.

[0233] As shown in FIG. 14, a user interface 20 is comprised of an LCD visual display 21a that displays the default interface for a Circuit Training Mode, characterized by a menu label 122d reading “CIRCUIT TRAINING”, such that the user may easily ascertain the selected mode of operation at any given moment in time. All output values read “0”, as the user has not yet begun the workout routine. In this interface, the primary visual display area 120 displays the user's instantaneous output power, measured in units of Watts. The secondary visual display area 122 displays more detailed information in the form of meters traveled (122a), SPM or Strides Per Minute (122b), and time elapsed (122c).

[0234] After mounting the exercise device, the user simply presses the “Go” button 124 and begins the workout routine. Time counter 122c begins tracking elapsed time, updating every second. The SPM display 122b measures the rate at which the user actuates the movable foot supports back and forth, with periodic updates on the order of one second. The meters traveled visual display 122c tracks cumulative distance over the course of the entire workout routine, updating only when a new integer value of distance is achieved. Of course, this figure refers not to a literal distance traveled by the user's body, but rather, the cumulative distance of the path(s) executed by the user's feet.

[0235] The user is not required to press the “Go” button 124 to begin a workout routine providing an additional degree of flexibility and ease of use to the hurried or novice user. By simply actuating the movable foot supports into their back and forth motion, the interface console is activated, the only difference being that a more limited set of information is subsequently presented to the user. Primary display area 120 will provide a reading of instantaneous power output in Watts exactly as described above, and SPM 122b will likewise function in an unchanged manner, because these instantaneous values are not time dependent in their measurement. However, display areas 122a and 122c, meters and elapsed time, respectively, will have no output. They are accumulated, time-dependent values, and as such, cannot be accurately displayed in the absence of a discrete, user-defined starting point.

[0236] FIG. 15 illustrates an example in which a user has begun a workout routine. The display interface itself is identical to that of FIG. 1, the only change being in the values presented. Accordingly, display area 122c indicates that the workout routine has been performed for 5 seconds, in which time the user has traveled a distance of 26 meters. Note that the presence of values in display areas 122a and 122c indicates that the “Go” button 124 was used to initiate this workout routine. Display areas 120 and 122b display the user's instantaneous output in terms of Power and SPM, respectively. As this workout is ongoing, input commands from buttons in panel 21b would have no effect, with the one exception being “Stop” button 126, which is employed to terminate the workout routine and all timing mechanisms.

[0237] After completing the workout routine and pressing “Stop” button 126, the interface of display 21a is replaced with a review interface, seen in FIG. 16. Label 131 in the top left corner indicates at all times to the user that the mode of operation is and was set to Circuit Training Mode, and furthermore, that the interface console is in the review interface. This review interface is only accessible after those workouts which were initiated by pressing the “Go” button 124. For those cases in which the button was not pressed, the display will return to the default interface depicted in FIG. 1 after the user ceases operation of the exercise device.

[0238] The review interface is designed to be simple and easy to understand, introducing no new measurements or other factors. It presents the user with just four values, tabulated into either averaged or accumulated form. Display areas 132a and 132b, average SPM and average Power, respectively, are averages that are measured over the complete duration of the workout routine, and provide a convenient form for the user to characterize his or her overall physical performance or output. Display areas 132c and 132d are the accumulated values for meters traveled and time elapsed, respectively.

[0239] FIGS. 17-21 illustrate the interfaces and operation of an Interval (as opposed to Circuit) Training Mode. FIG. 17 depicts the first of three input interfaces, which are presented to the user prior to the beginning of the workout routine. Menu label 122d has changed to read “INTERVAL TRAINING”, such that the user may easily ascertain the selected mode of operation at any given moment in time. Command prompt 134 reads “SET WORK TIME”, informing the user that he or she is choosing the amount of exercise time that each interval should consist of. Primary display area 120 provides a display of the currently selected amount of work time, in seconds. Arrow keys 130a and 130b are used to increment or decrement the work time as desired. Once the work time is suitably adjusted, the user presses “Enter” button 124 and is taken to the second input interface screen, seen in FIG. 5.

[0240] Two changes distinguish FIGS. 17 and 18. FIG. 18 uses an inverted color scheme as compared to FIG. 17, and the command prompt 134 has updated to “SET REST TIME”, in order to inform the user that he or she is choosing the amount of resting, non-exercise time that each interval should consist of. By utilizing an inverted color scheme, it becomes far easier for the user to distinguish between the two discrete input steps, as he or she would be more likely to fail to recognize the change if only command prompt 134 updated between the two input steps. The amount of time that the rest period shall consist of is set in a manner identical to the one described above. The amount of work time and rest time need not be equal. Once the rest time is suitably adjusted, the user presses “Enter” button 124 and is taken to the final input interface screen, seen in FIG. 19.

[0241] As between FIGS. 18 and 19, the color scheme inverts once again, continuing the process of aiding the user in recognizing requests for new information or inputs. Command prompt 134 has updated to “SET TOTAL INTERVALS”, informing the user that he or she is choosing the number of intervals that the workout routine shall consist of. Note that one interval consists of a single work period followed immediately by a single rest period. As in the previous two input interfaces, primary display area 120 displays the adjustable, currently selected input value. As before, this value is incremented or decremented by arrow keys 130a and 130b. A smaller display area, 120b, is introduced in this interface, and provides the user with a convenient readout of how long the total workout routine will last, based on the prior inputs of work time and rest time and the current input of total intervals. This readout is re-calculated and adjusted concurrent with any adjustments that the user may make to the total number of intervals. After pressing “Go” button 124, the user now begins the interval workout routine.

[0242] FIG. 20 illustrates the interface presented while the interval training workout is ongoing. Note the similarity between said interface and the circuit training interface of FIGS. 1 and 2. While these two interface screens would never be seen one after another, the difference between the two screens is nevertheless emphasized by the use of contrasting color schemes. The bottom three display areas 122a-c are highly similar between the two different interface modes. 122a and 122c are identical to as described above, and 122b is identical to the Power measurement display described above, but relocated to a different zone of the display.

[0243] In Interval Training Mode, display label 122d has changed to read “INTERVAL SETS 5”, such that the user may easily ascertain that he or she is currently in Interval Training Mode, and such that the user may furthermore keep track of the number of intervals, or sets, remaining. While the number five is seen in FIG. 20, note that this is solely for purposes of example, as in reality, the number seen on the display updates in real-time to indicate the number of intervals remaining in the workout routine. D

[0244] Immediately after the workout routine is initiated by the user, the first interval begins, starting with the work/exercise portion. The user's current state, or position in the cycle of the interval, is indicated in the top left corner of primary display area 120, by a label reading either “WORK” or “REST”. In both the work and rest steps, a large counter fills primary display area 120, beginning at the predetermined amount of time selected by the user via the process described above. The counter then decrements second by second, until it expires at zero.

[0245] When the counter expires at zero, the next step of work or rest commences, and this cycle of intervals continues until the user presses “Stop” button 126 or the input number of total intervals is completed in full. Once the workout routine is either terminated or expires on its own, the user is presented with the review interface of FIG. 21. Label 131 in the top left corner indicates at all times to the user that the mode of operation is and was set to Interval Training Mode, and furthermore, that the interface console is in the review interface. The review interface is designed to be simple and easy to understand, introducing no new measurements or other factors. It presents the user with just four values, all tabulated into accumulated form. Display area 132a presents the user with the total number of full sets performed over the duration of the workout routine, and 132b similarly presents the user with the total distance, in meters, executed by his or her foot path(s). Display area 132c is shown depicting the average power output of the user, in watts, while display area 132d presents the total amount of elapsed time spent performing the interval training routine.
