Description of the Preferred Embodiment
FIG. 1 illustrates an exercise apparatus 10 of the type having a base 12 and a pivoted lever arm 14 pivotably connected at a fixed lever end 16 to the base 12. Lever arm 14 has a free lever end 18 which is forwardly spaced and extends generally transversely from base 12. Free lever end 18 is provided with a pin 20 which provides means for selectively receiving weights. In a preferred embodiment illustrated in FIG. 1, pin 20 extends generally upwardly to engage the center hole of standard annular free weights. It will be readily apparent to those skilled in the art that other means for selectively receiving weights at free lever end 18 also fall within the scope of the present invention.
The tower attachment of the present invention is generally designated 22 and has an elongate tower support 24 which, in a preferred embodiment illustrated in FIG. 1, comprises vertical columns 26 and 28, although those skilled in the art will readily appreciate that such tower support 24 could take many other forms. The tower attachment 22 has a low tower end 30, which in the illustrated embodiment includes an upper connecting arm 32 and a lower connecting arm 34, with pin 35, by which tower attachment 22 can be connected to base 12 of exercise machine 10. Those skilled in the art will readily appreciate that other design configurations for connecting elongate tower attachment 22 to base 12 fall within the scope of the present invention.
Upper connecting arm 32 is provided with connecting means 36 by which it can connect to elements of base 12. As best seen in FIG. 1A, the illustrated invention discloses that connection means 36 may be a slotted sleeve sized to engage a vertical post of base 12. A pin 37 passes through the slots of the connection means 36 and can receive any of a plurality of means by which the slotted sleeves may be tightened to the support element, such as a clamp or a winged nut where the pin is threaded. In the embodiment illustrated in FIG. 1, lower connecting arm 34 is provided with a free end sized to fit within an open end of a support element of base 12 and secured with a pin 35 or other removable fastener.
In a preferred embodiment illustrated in FIG. 1, a high tower end 38 of tower attachment 22 is provided with a horizontal support bar 40, having a pair of pulleys 42 and 44 at each end, respectively.
A flexible tensile member 46 has sufficient length to extend across pulleys 42 and 44 at the respective ends of horizontal support bar 40. A first end 48 of flexible tensile member 46 may include an adjustment strap 50 by means of which the effective length of flexible tensile member 46 may be selectively adjusted. As shown in the illustrated embodiment, adjustment strap 50 may be provided with articulating clips to attach to both first end 48 of flexible tensile member 46 and a connecting bracket 52, which may be selectively attached to a plurality of locations 54 disposed along lever arm 14 at positions distal from fixed lever end 16. Those skilled in the art will appreciate that other designs pivotably connecting affixing first tensile member end 48 to the plurality of spaced locations 54, both adjustably and unadjustably, fall within the scope of the present invention.
Those skilled in the art will likewise appreciate that alternative designs of high tower end 38 also fall within the scope of the invention, including for example, replacement of horizontal support bar 40 and its respective pulleys 42 and 44 with a single pulley disposed at a height sufficient such that flexible tensile member 46 has sufficient clearance over elements of exercise machine 10 such as the adjustable elbow pad illustrated in FIG. 1. Thus, the interrelated features which inform the many acceptable designs within the scope of this invention include the height of the tower support 24, the width of horizontal support bar 40, if any, the possibility of removal of any obstructions on exercise machine 10, such as the elbow pad, and the length of lever arm 14.
Furthermore, alternative embodiments of flexible tensile member 46 and the pulleys 42 and 44 which engage the intermediate portion of flexible tensile member 46 include flexible tensile member 46 being a cable and pulleys 42 and 44 having smoothed grooves to engage the cable, or flexible tensile member 46 being a chain and pulleys 42 and 44 being provided with teeth to engage said chain.
A second end 56 of flexible tensile member 46 extends below high tower end 38 and is adapted to engage a handle 58 such as a pull-down bar or to engage a second flexible tensile member 60. For this purpose, second tensile member end 56 or second flexible tensile member 60, or both, may be provided with a clip or other connector. It may be noted in FIG. 1 that tower support 24, and particularly vertical column 28 in the illustrated embodiment, may be provided with a storage means 62 such as a hook to selectively store either second flexible tensile member 60 or handle 58 when the other respective component of this pair is in use.
FIG. 1 further illustrates that low tower end 30 of tower attachment 22, and particularly vertical column 28 of tower support 24 of this embodiment, may be provided with a lower pulley 64 adapted to engage second flexible tensile member 60. The end of second flexible tensile member 60 which extends past lower pulley 64 includes connection means to selectively connect to a handle 66 such as a rowing handle. Low tower end 30 is also provided with a transverse foot block bar 68, which in turn engages a pair of foot blocks 70 by which a user may brace his feet during certain exercises such as a rowing exercise.
FIG. 2, in full and in shadow lines, show the operation of tower attachment 22 during a user's rowing exercise.
A shoulder bar attachment, generally designated 70, of the present invention is best illustrated in FIG. 5. Shoulder bar attachment 70 has a generally elongate body 72 with a first body end 74 and a second body end 76. The central region of elongate body 72 between first end 74 and second end 76 is generally aligned along a longitudinal axis. In a preferred embodiment, the elongate body 72 may comprise a pair of elongate members 78 and 80, respectively, which are spaced apart at least a distance which is sufficient to form a central opening to accommodate the head of a user of the shoulder bar 70 as attached to exercise machine 10. A pair of handles 82 is preferably padded and rotatably mounted upon elongate members 78 and 80 at first body end 74, the handles 82 extending along a transverse axis which is generally perpendicular to the longitudinal axis of elongate body 72. The second body end 76 is provided with pivotable connection means 84 for pivotally connecting the shoulder bar attachment 70 to any of a plurality of locations 54 disposed along lever arm 14.
In a preferred embodiment illustrated in FIG. 5, pivotable connection means 84 comprises a bracket having a bracket arm and a rotatable sleeve which engages a connecting rod 86 disposed at second body end 76 and connecting elongate member 78 and elongate member 80. In an alternative embodiment, each of elongate members 78 and 80 may be a unitary tube whose ends at second body end 76 are connected by engaging a surrounding, rotatable sleeve upon which pivotable connection means 84 is disposed.
In a preferred embodiment illustrated in FIG. 5, elongate members 78 and 80 are a pair of tubes each of which is of generally elongated U-shape. Thus, elongate members 78 and 80 each have a first section 86 which is generally elongate and lies along the longitudinal axis of generally elongate body 72. Each of elongate members 78 and 80 additionally has a second section 88 which extends generally orthogonally to both first section 86 and handles 82. As seen in both FIGS. 3 and 4, the purpose of the orthogonally oriented second section 88 of elongate members 78 and 80 is to allow the first body end 74 of shoulder bar 72, which is the user's end, to accommodate the shoulder of the user, in turn allowing the handles 82 to be grasped forward of the user's torso.
As seen in FIG. 5, as well as in FIGS. 3 and 4, the second body end 76 of shoulder bar 70 is also provided with an orthogonal section similar to second section 88 of elongate members 78 and 80 and which, in combination with second section 88 give elongate members 78 and 80 its earlier described generally elongate U-shape. As best noted in FIG. 4, the orthogonal section at second body end 76 provides a similar function to orthogonal section 88 located at first body end 74, but with respect to accommodating the user's lower torso and legs.
FIG. 3 illustrates use of the shoulder bar 70 of the present invention, in combination with exercise machine 10, during an inclined bench press exercise. It should be noted that while the shadow lines of FIG. 3 show a bench press which brings the user's arm from the solid line position to a single extended position, an additional advantage of the pivotable connection means 84 is that the user can perform an inclined bench press at various angles within a wide range. As a result, the user has greater flexibility to gear development at variable precise portions of involved muscle groups.
