Integral treadmill resistance training apparatus

[0001] The present application is a nonprovisional application of, and claims priority to, U.S. Provisional Application Ser. No. 61/109,092, filed Oct. 28, 2008, which is hereby incorporated by reference into this application.

[0002] The present invention relates to resistance training exercise apparatus. More particularly, the present invention relates to exercise treadmills with integral resistance training means for resistance training strength workouts.

[0003] Home exercise machines are widespread. Some machines provide aerobic exercise, such as treadmills and other “cardio machines,” Some machines provide strength training such as weight machines and resistance machines using elastic straps or resistance gears. Examples include such suppliers as BOWFLEX™ and NAUTILUS™. These machines have drawbacks, however. These machines are essentially single purpose—they provide either a cardio workout or a strength workout, but can't provide for both in the same footprint. Most people have limited space in their home or office to store and use exercise equipment and don't have room for both a cardio machine and a strength machine. These machines can also be quite expensive. The cost of purchasing a stand-alone cardio machine and a stand-alone strength machine can be prohibitive for many. Limited space available in user's homes may also preclude two separate machines.

[0004] An effective strength training machine should provide for multiple positions and multiple angles of resistance in order to work different muscle groups. An effective strength training machine should provide for exercises in the supine and standing positions. Users would benefit greatly from being able to integrate strength training exercises into a single cardio-strength training machine rather than have to obtain separate machines.

[0005] Thus, there is a need for an apparatus which integrates an exercise treadmill with strength training means into a single machine without negating its ability to operate as a treadmill.

[0006] A number of devices have provided treadmills or resistance exercises, but lack the ability to integrate the two together to create an operating treadmill for resistance training, with the ability to perform exercises in a sitting or supine position as well as while walking on the treadmill. Presently known art attempts to address this problem, but has not completely solved the problem. The following represents a list of known related art

Mounting bracket 1020 includes anchor 1038 with locking pin and washer 1041 for connecting resistance straps 1040 to mounting bracket 1020. In the embodiment axle bolt 1048 and anchor 1038 are mounted from the inside of mounting bracket 1020 oriented outward, so that a user does not have to drill through treadmill support columns VR and VL to attach the vertical mounting bracket 1020. Alternatively, anchor 1038 may be a fixed bolt or post.

[0061] Referring to FIGS. 8 and 9, translation member 1050 includes opposing first and second plates 1052 and 1054, respectively, which are bolted together via spacers 1056 and bolts 1058 with retaining nuts 1059. Matching index holes 1060 and 1062 are distributed radially about center mounting holes 1053 and 1055 for locking articulated handle 1080 at the desired angular orientation to translation member 1050 using a pair of locking pins 1042.

[0062] Articulated handle 1080 includes a first part 1082 connectable to translation member 1050 at a selected angular orientation to translation member 1050 and a second part 1088 rotatingly connected to handle first part 1082 at joint 1090. Handle first part 1082 includes handle first part mounting hole 1086 for receiving axle bolt 1048, and handle first part indexing holes 1084 and 1085 for receiving removable locking pins 1042 when aligned with index holes 1060 and 1062. Joint 1090 includes first and second joint plates 1092 and 1094, respectively, fixed on opposing sides of hand first part 1082 and having matching joint index holes 1096 and 1098 and center mounting holes 1100 and 1102 (1102 not visible in the views), and first and second friction disks 1104 and 1106. Handle second part 1088 has a mounting hole 1108, index hole 1110 and hand grip 1112. When assembled, handle second part 1088 fits between first and second joint plates 1092 and 1094. First and second friction disks 1104 and 1106 fit into the spaces between handle second part 1088 and first and second joint plates 1092 and 1094. Handle second part mounting hole 1108 and friction disks 1104 and 1106 align with joint plate center mounting holes 1100 and 1102 to receive joint axle bolt 1116. In the embodiment joint axle bolt 1116 includes a knurled or petal-shaped handle grip for ease of use. An index locking pin 1042 is provided to engage joint index holes 1096 and 1098 with handle second part index hole 1110, thereby allowing handle second part 1088 to be locked in a desired angular orientation to handle first part 1082. Alternatively, with index pin 1042 removed, handle second part 1088 may be rotated about joint 1090 for exercise, with friction resistance provided by friction disks 1104 and 1106. In the embodiment friction disks 1104 and 1106 are made from plastic material such as nylon for ease of manufacture and minimal expense, as they will wear over time, but any suitable material may be used.

[0063] One or more resistance straps 1040 are provided for connecting between mounting bracket 1020 and translation member 1050. Resistance strap 1040 connects at a first end 1046 to mounting bracket 1020 via anchor 1038 and at a second end 1044 to translation member 1050 using a locking pin 1042 through translation member index holes 1060 and 1062. In the embodiment resistance strap 1040 is made from a strong stretchable material such as butyl rubber, but other stretchable materials such as silicone rubber or other suitable materials could be used. Additionally, flexible straps 1120 may be attached to translation member 1050 using a locking pin through index holes 1060 and 1062 in order to increase the range of exercises available. In the disclosed embodiment flexible straps 1120 are bungee cords or surgical tubing.

[0064] Referring to FIGS. 6-9, in operation the second embodiment of a treadmill conversion resistance training apparatus, a user begins by assembling and mounting the conversion apparatus to a treadmill. Assembly involves inserting axle bolt 1048 and anchor 1038 through connection point 1034 and hole 1039 (if not permanently mounted), respectively, then mounting the attachments 1010a and 1010b around respective treadmill support columns VR and VL by sandwiching first and second mounting bracket parts 1022 and 1024 around each of support columns VR and VL, tightening adjustable securing straps 1036 to hold them tightly, and threading locking handles 1028 through slotted holes 1026 to lock first and second parts 1022 and 1024 in place. Articulated handle 1080 is inserted into translation member 1050 and aligned at a desired angle, and locking pins 1042 are inserted through index holes 1060, 1062, 1084 and 1085. Translation member 1050, with handle 1080 mounted therein, is attached to connection point 1034 using axle bolt 1048 and retaining nut and washer 1051. Retaining nut and washer 1051 lock to prevent backing off axle bolt 1048, but do not lock translation member 1050 from rotation. Translation member 1050 is free to rotate about axle bolt 1048.

[0065] Resistance strap 1040 is connected at first end 1044 using anchor 1038, and at a second end 1046 to translation member 1050 using a locking pin 1042. Resistance strap 1040 may be connected at any of the indexing holes 1060 and 1062, thereby allowing a user to accommodate straps of differing length. The user may also selectively adjust the angle of handle 1080 by selecting different index holes 1060 and 1062, to accommodate different user heights or different ranges of motion. Use of additional resistance straps 1040 allows incremental increase in resistance and therefore the intensity of exercises. Attaching resistance strips 1040 to translation member 1050 at a radial distance from axle bolt 1048 provides a smooth, essentially linear resistance profile. Resistance strap 1040 could also be attached to handle 1080 and function adequately.

[0066] Articulated handle joint 1090 allows a user to lock handle 1080 at a selected angle in order to utilize resistance straps 1040 for exercise, or to unlock handle joint handle joint 1090 and use handle 1080 for resistance exercising. Resistance of handle joint 1090 to rotation is adjustable by adjusting the tightness of joint axle bolt 1116—i.e. tightening joint axle bolt 1116 compresses joint plates 1092 and 1094 against friction disks 1104 and 1106, thereby increasing resistance, while looseing joint axle bolt 1116 reduces resistance.

[0067] A user may utilize articulated bench 200, shown in FIG. 4, placed over treadway Tin order to perform bench presses, shoulder presses, and other traditional strength exercises from a supine, prone, or sitting position. Alternatively, a user could lay a pad directly on treadway T and lie or sit on the pad to perform exercises.

[0068] Referring to FIG. 7, the nature of movement of the translation member 1050 and articulated handle joint 1090 are shown by hidden lines. Varying the angle of handle 1080, and/or the connection point of resistance strap 1040 to translation member 1050, and/or the model of resistance strap 1040, and/or the angle of joint 1090, and/or the rotational resistance of joint 1090, allows the treadmill resistance training apparatus to accommodate a wide range of user heights, abilities, and exercises of various ranges of motion and resistance profiles.

[0069] The treadmill resistance training apparatus 1000 is easily removable by reversing the attachment steps described above. A user may choose to simply leave the resistance training apparatus attached, as the apparatus does not interfere with the normal operation of the treadmill.

[0070] Referring to FIG. 10, an integral treadmill resistance training apparatus 2000 is shown, including treadmill 2002 having forward and 2004, an aft end 2006, a treadway 2008, and left and right support columns 2010a and 2010b; first and second translation members 2050a and 2050b, each of first and second translation members 2050a & b rotatingly connected to left and right support columns 2010a & b, respectively, at translation axes 2034a and 2034b, each of the translation members having locking pins 2042a and 2042b for removably connecting one or more resistance straps (not shown) at one or more locations; first and second handles 2080a and 2080b connected to the first and second translation members 2050a & b, respectively; locking pins 2122a and 2122b for locking each of the first and second handles 2080a & b at an adjustable angular orientation in relation to the first and second translation members 2050a & b, respectively, such that moving the locked handles 2080a and b causes the respective translation members 2050a & b to rotate about the respective translation axes; and, one or more resistance straps removably connectable between each of the first and second translation members 2050a & b and the left and right support columns 2010a & b, respectively, Control panel 2009 provides controls for treadmill 2002.

[0071] As shown in FIG. 10, the separation distance between first and second translation members 2050a & b is adjustable to accommodate users of different sizes and to concentrate on different muscle groups. In the embodiment the separation distance is adjusted by moving support columns 2010a & b closer together or farther apart, by removing locking pins 2130a & b and sliding support columns 2010a & b toward or away from each other along mounting rail 2132, and reinserting locking pins 2130a & b. In the embodiment support columns 2010a & b are slidably mounted around a rail to facilitate adjustment.

[0072] As shown in FIG. 10, the height of first and second translation members 2050a & bin relation to treadway 2008 is adjustable to accommodate users of different heights and to adjust between standing use and prone use. In the embodiment adjustment is provided by connecting translation members 2050a & b to sleeves 2140a and 2140b, which sleeves 2140a & b are slidably connected to support columns 2010a & b, respectively. Sleeves 2140a & b are locked in place using locking pins 2142a & b, respectively. Anchors 2038a and 2038b project from sleeves 2140a & b, respectively, so that height adjustment will not affect the tension of resistance straps (not shown) connectable between anchors 2038a & b and translation members 2050a & b. Handles 2080a & b are indexable, articulated, lockable handles with adjustable rotating resistance at joints 2090a & b.

[0073] Referring to FIG. 11, a second embodiment of an integral treadmill resistance training apparatus 3000 is shown in profile cut-away view showing only a left-side of the apparatus 3000, including a treadmill 3002 having forward end 3004, aft end 3006 and treadway 3008. Left support column 3010a extends upward from the treadmill 3002. Left support column sleeve 3140a provides vertical adjustment of left translation member 3050a. The opposing right-side of apparatus 3000 is a mirror image. As shown in FIG. 11 each side of apparatus 3000 includes one or more resistance straps 3040a removably connectable between anchors 3038a and the respective translation member 3050a in a rearward orientation, and one or more resistance straps 3041a removably connectable between anchors 3038a and the respective translation member 3050a in an opposing forward orientation. In this way, if translation member 3050a is rotated clockwise (i.e. the user lifts or pushes handle 3080a upward) then resistance strap 3040a provides resistance, and if translation member 3050a is rotated counter-clockwise (i.e. the user depresses or pushes handle 3080b downward) then resistance strap 3041a provides resistance. In the embodiment resistance straps 3040a and 3041a are thin flexible straps or chords so as to not provide resistance in compression. Resistance strap 3040a is removably connected at a first end to anchor 3038a and at a second end to translation member 3050a using locking pin 3124. Resistance strap 3041a is removably connected at a first end to anchor 3038a and at a second end to translation member 3050a using locking pin 3126. Handle 3080a includes locking, indexable, variable resistance articulation joint 3090a. Handle 3080a is locked in a selected indexed position in relation to translation member 3050a using locking pins 3042 inserted through translation member indexing holes 3060a.

[0074] As shown in FIG. 11, resistance straps may be pre-tensioned. Pre-tensioning allows resistance straps to be connected more easily in a non-tensioned condition, and then pre-tensioned prior to use to provide continuous resistance throughout the range of motion. In the embodiment pretensioning is provided by making anchors 3038a (and 3038b, not shown) adjustable.

[0075] Referring to FIGS. 12 & 13, and embodiment 4000 is shown having adjustable grips 4150. Only the right-hand adjustable grip 4150 is shown for illustration as the left-hand adjustable grip is identical in the disclosed embodiment. Articulated handle 4080 includes a handle second part 4088 connected to handle joint 4090. Adjustable grip 4150 includes a first portion 4152 connected to handle second part 4088, and a hand grip portion 4154 extending from first portion 4152. In the embodiment, hand grip portion 4154 includes a first length 4156 extending from first portion 4152 at an obtuse angle and a second length 4158 continuing substantially parallel to first portion 4152, so that hand grip portion 4154 provides an offset grip ability. A user may also grip either the first length 4156 or the second length 4158 depending on the exercise in order to adjust wrist rotation angle. In the embodiment, first portion 4152 fits over handle second part 4088 like a sleeve so a user may slide it linearly to adjust the effective handle length, or rotate about the axis of handle second part 4088 to adjust the angle and orientation of grip. Selective linear and rotational adjustment is provided by locking mechanism 4160 which releasably engages adjustable grip first portion 4152 with handle second portion 4088. In the embodiment, locking mechanism 4160 includes a spring-loaded locking pin 4162 selectively engageable with grip fixed locking holes 4164, or with elongated translational locking hole 4166 to permit partial rotation of the adjustable grips about the handle axes.
