DETAILED DESCRIPTION

[0017] The following detailed description will illustrate the general principles of the invention, examples of which are additionally illustrated in the accompanying drawings. In the drawings, like reference numbers indicate identical or functionally similar elements.

[0018] Referring to FIGS. 1-3, a bar and hand grips kit 100 has an elongate, hollow bar 102 having a connector 103 protruding outward from a mid-section 110 thereof, at least left and right hand grips 120 and a plurality of fasteners 130. The connector 103 defines a first eyelet 105 shaped to be releasably connectable to a connector of a pulley cable of an exercise machine. The bar 102 has a plurality of transverse bores 104 set pre-selected distances apart that begin from each end 106, 108 and move toward the mid-section 110 of the bar. Also, the bar 102 has a plurality of elongate slots 112 in a surface 111 (shown in FIG. 3) opposite the connector 103. The plurality of elongate slots 112 are set a pre-selected distance apart from one another and begin from each end 106, 108 and move toward the mid-section 110 of the bar. In the embodiment, shown in FIG. 3, there are four elongate slots 112 in both ends 106, 108 of the bar 102. The bar, however, is not limited thereto. If the bar was solid, each of the plurality of elongate slots 112 would have a depth into the bar 10 sufficient for alignment with one of each of the plurality of transverse bores 104 such that a respective bore 104 transects a respective slot 112.

[0019] The kit 100 has a plurality of circular hand grips 120 each fixedly, rotationally mounted to an arch 122 by a fastener 121 at each mounting point 123. The plurality of circular hand grips, at a minimum, is a left hand grip 120 and a right hand grip 120, but the kit can have any number of such hand grips as each are interchangeable with one another. The arch 122 of each circular hand grip 120 has a connector pivot 124 protruding radially outward from an apex 126 of the arch. Each connector pivot 124 defines a second eyelet 128 axially therethrough and is shaped to be seated in any one of the plurality of elongated slots 112 with the eyelet 128 in alignment with a respective transverse bore 104 of the bar 102 and is shaped to be releasably connectable to a connector of a pulley cable of an exercise machine independent of the bar 102. The fasteners 121 can be threaded screws or bolts, fixed pins, or any other suitable fastener. Both the left hand grip 120 and the right hand grip 120 are freely rotatable clockwise/counterclockwise about a center axis of rotation (A.sub.R) and are freely rotatable about an X axis oriented transverse to the axis of rotation and aligned with the central handle 138 of each of the left and right hand grips 120.

[0020] As used herein, “free rotation” or “freely rotatable” is rotation through 360 or more degrees in two opposing directions, e.g., clockwise and counterclockwise, forward and backward, etc.

[0021] Turning to FIGS. 1, 2 and 5, the kit 100 includes a plurality of fasteners 130 repeatedly, removably receivable in any one of the plurality of transverse bores 104 and through any of the second eyelets 128 in a connector pivot 124 simultaneously to securely, replaceably mount each hand grip 120 to the bar 102. Each of the plurality of fasteners 130 has a post 180 receivable in any of the plurality of bores 104 and either of the second eyelets 128 simultaneously when the connector pivot 124 is received in one of the slots 112 in the bar. Each of the plurality of fasteners 130 has a head 182 that is shaped to conform to the shape of the exterior surface of the bar 120. In one embodiment, the bar 120 is cylindrically shaped and the head 182 of each of the plurality of fasteners 130 is arcuately shaped to partially wrap around the exterior surface of the bar 102. As shown in FIGS. 5 and 2, the arcuately shaped head 182 wraps over the top surface of the bar and covers the front face of the bar 102. The arcuately shaped head 182 may have an arcuate length of 100 degrees up to 180 degrees of a circle. In another embodiment, the bar 102 may be square or rectangular in cross-section and the head 182 of each of the plurality of fasteners 130 is shaped to mate against the exterior surface of the bar 102, thereby being generally L-shaped. Each of the plurality of fasteners 130 is rated to handle 350 pounds. In one embodiment, the fasteners 130 are made of plastic. In another embodiment, the fasteners 130 can be made of metal or a combination of metal and plastic.

[0022] As shown in FIG. 2, in the assembled state, the connector pivot 124 of each of the left and right hand grips 120 is received, respectively, in a first selected slot 112 and a second selected slot 112 of the plurality of slots of the bar 102. The connector pivot 124 is generally triangularly shaped with the base of the triangle connected to the arch 122. Here, the hand grips 120 are shown received in the centermost slots 112. The first fastener 130a is received in the bore 104 oriented transverse to the first selected slot 112 and in the second eyelet 128 of the left hand grip. Likewise, the second fastener 130b is received in the bore 104 oriented transverse to the second selected slot 112 and in the second eyelet 128 of the right hand grip 120. Each of the first fastener 130a and the second fastener 130b define a pivot point (PP) about which the left and right hand grips 120 pivot within the first selected slot 112 and the second selected slot 112, respectively. Each pivot point (PP) provides a range of motion (arrow (C)) relative thereto of up to plus or minus 10 degrees. “Plus” degrees herein is to the right in FIG. 2 and “minus” degrees is to the left in FIG. 2. Referring to FIG. 3, to accommodate the preselected degree of motion (+/−10 degrees) about each pivot point (PP), each of the plurality of slots 112 has a length (L) that is greater than the width of the connector pivot 124 at the slot mouth 113 in the bottom surface 111 of the bar 102. Each of the plurality of slots 112 has a width (W) that is wide enough to receive the connector pivot 124 of each of the hand grips 120.

[0023] In the embodiment of FIG. 3, the spacing between the plurality of slots 112 from the first end 106 toward the midsection 110 of the bar 102 (a first set of slots) and from the second end 108 toward the midsection 110 of the bar 102 (a second set of slots) are shown to be the same as one another and have equal spacing between slots within each of the first and second set of slots. Equal spacing between the slots within each set of slots is not required. The spacing should be pre-selected based upon the handle positions needed for the different exercises to be performed by the user relative to the configuration of a selected pulley cable exercise machine.

[0024] Turning now to FIG. 4, each circular hand grip 120 has and arch 122 that has the connector pivot 124 described above, an outer annular handle portion 134 and an inner annular handle portion 132 seated circumferentially within the outer annular handle portion 134 with an annular roller bearing 136 seated therebetween such that the inner annular handle portion 132 is freely rotatable (clockwise and counterclockwise) about an axis of rotation (A.sub.R) (best seen in FIG. 1) relative to the outer annular handle portion 134. The outer annular handle portion 132 has opposing mounts 140, which may have internal threading, protruding radially outward from an exterior surface of the ring 142. The arch 122 terminates at opposing ends with mating mounts 123 that each receive one of the opposing mounts 140 of the outer annular ring 134. The mating mounts 123 may have threaded or partially threaded bore holes 125. Here, the opposing mounts 140 are seated in the mating mounts 123, but the opposite configuration is also possible. The mated mounts and fastener 121 facilitate the free rotation of the left and right hand grips 120, respectively, relative to the arch 122 about the A.sub.X axis.

[0025] Still referring to FIG. 4, the inner annular handle portion 132 is defined by a front annular grip portion 132a and a back annular grip portion 132b that are fixedly mated to one another at axially facing interior surfaces 133a, 133b, optionally by fasteners 144 such as threaded screws, and define a central handle 138 and define an internal annular seat 139 for the annular roller bearing 136. The interior surface 133a of the front annular grip portion 132a has hollow posts 137 protruding axially toward the back annular grip portion 132b, which may have internal threading, for receiving a fastener 144 therein that passes through a bore 143 in the back annular grip portion 132b. In another embodiment, the front annular grip portion 132a and the back annular grip portion 132b may have a snap fit to one another, be adhered to one another, or welded to one another.

[0026] The annular roller bearing 136 has an inner race 150, an outer race 152, a bearing cage 154, and a plurality of balls or rollers 156. The inner race 150 is seated on the annular seat 139 defined by the front and back annular grip portions 132a, 132b. In the illustrated embodiment, the bearing cage 154 is a “J” type cage, but is not limited thereto. A “J” type cage has a two-piece ribbon consisting of two halves that are assembled one half from one side and the other half from the opposite side. Fold down tabs or rivets typically secure the two halves. This type of cage is guided by the balls. The annular roller bearing 136 facilitates the free rotation of the inner annular handle portion 132 relative to the outer annular handle portion 134.

[0027] The kit 100 is advantageous because it allows for a more natural and ergonomic range of exercise motion of the user because the hand grips rotate and pivot to accommodate the users natural motion and relieve stress on the wrists. In contrast, if a user grabs a handle consisting of two vertical, spaced-apart hand grips fixedly attached to (no rotation possible) and spaced a distance of about five inches from a connector plate with their arms fully extended to the front, and pull those handles toward their chest, the user's wrists will become more perpendicular to the forearms, thereby putting undue stress on the wrists.

[0028] Also, the bar and hand grips kit eliminates the need to buy a plurality of different handles and bars that are currently available for pulley cable exercise machines. The kit 100 is all that is needed because the myriad hand grip positions/combinations are suitable for a multitude of exercises using a pulley cable exercise machine.
