This application relates to bar and hand grips kits for exercise equipment, more particularly, to a kit for cable pulley exercise machines that has a bar with a plurality of slots for receiving a left hand grip and a right hand grip in a plurality of positions relative thereto, wherein both of the left and right hand grips are rotatable in two planes and are pivotable relative to the attachment point with bar.
Cable pulley exercise machines are a staple in most every gym. These machines require the user to attach one of many different types of handles or bars to the cable system in order to perform an exercise. Current handles/bars suffer from at least three problems. First, most handles are solid pieces of metal with zero to one moving part. This forces the user's wrists to remain nearly static relative to the handle during all movements of their exercise. Since the user's wrists naturally go through different positions and angles in different motions, current handles/bars are not ergonomic and can cause discomfort or injury. Second, there are a multitude of different types and designs of handles/bars for the cable pulley exercise machines. This can be expensive to accumulate, and in a gym setting, replace. Also, handles/bars are commonly misplaced in the gym, thereby forcing users to skip intended exercises or use the wrong handle for a particular exercise. Additionally, searching for and attaching different handles/bars to the machine is inefficient. Lastly, many exercises require the user to rotate and pivot their wrists. Doing this allows for additional elongation and contraction of muscles such as the bicep. Most, if not all, exercises cannot be properly done on a cable pulley exercise machine and require the users to switch to free weights or special and expensive machines for some of the exercises.
Thus, there is a need for an improved bar and hand grip kit that solves all of these problems.
In one aspect, bar and hand grips kits for exercise equipment are disclosed that have an elongate bar having a connector defining a first eyelet protruding outward from a mid-section thereof, having a plurality of elongate slots into the bar positioned in a surface opposite the connector, and a plurality of bores oriented one each transverse to one each of the plurality of elongate slots, a left hand grip and a right hand grip each having a connector pivot protruding outward therefrom that defines a second eyelet and is shaped to be received in any of the plurality of elongate slots in the bar with the second eyelet aligned with a respective one of the plurality of bores, and a first fastener and a second fastener each repeatedly, removably receivable in any one of the plurality of bores and second eyelets. In an assembled state with the connector pivot of each of the left and right hand grips received, respectively, in a first selected slot and a second selected slot of the plurality of slots of the bar and the first fastener received in the bore oriented transverse to the first selected slot and in the second eyelet of the left hand grip and the second fastener received in the bore oriented transverse to the second selected slot and in the second eyelet of the right hand grip, wherein each of the first fastener and the second fastener defines a pivot point about which the left and right hand grips, respectively, pivot within the first selected slot and the second selected slot. Both of the left hand grip and the right hand grip are freely rotatable clockwise about a center axis of rotation and are freely rotatable about an X axis oriented transverse to the center axis of rotation.
In all embodiments, each pivot point provides a range of motion with respect to the pivot point of plus or minus 10 degrees. Each of the first fastener and the second fastener has a post receivable in any of the plurality of bores and either of the second eyelets and a head that is shaped to conform to the shape of the exterior surface of the bar. The bar is cylindrical in shape and the head of each of the first and second fasteners is arcuately shaped to partially wrap around the exterior surface of the bar.
In all embodiments, each of the left hand grip and the right hand grip can be circular grips fixedly, rotationally mounted to an arch that has the connector pivot protruding therefrom. Each circular grip has an outer annular handle portion, an inner annular handle portion seated circumferentially within the outer annular handle portion, and an annular roller bearing seated between the outer annular handle portion and the inner annular handle portion. The inner annular handle portion is defined by a front annular grip portion and a back annular grip portion that are fixedly mated to one another at axially facing surfaces. Each arch terminates at opposing ends with threaded bore holes aligned with threaded mounts on the outer annular handle portion, and threaded fasteners are seated in the threaded bore holes and threaded mounts. The front annular grip portion and the back annular grip portion are fixedly fastened to one another and define a central handle and define an annular seat for the annular roller bearing. The annular roller bearing has an inner race, an outer race, a bearing cage, and a plurality of bearings. The inner race is seated on the annular seat defined by the front and back annular grip portions.
In all embodiments, the first eyelet and each of the second eyelets are shaped to be releasably connectable to a connector of a pulley cable of an exercise machine.
In another aspect, a hand grip for connection to a cable of a pulley cable exercise machine is disclosed that has an arch having a connector protruding outward therefrom that defines an eyelet and terminating at opposing ends that each have a bore hole, an outer annular handle portion having mounts positioned and aligned one each with a bore hole in the arch for free rotation therein relative to the arch, an inner annular handle portion seated circumferentially within the outer annular handle portion, and an annular roller bearing seated between the outer annular handle portion and the inner annular handle portion. The inner annular handle portion is defined by a front annular grip portion and a back annular grip portion that are fixedly mated to one another at axially facing surfaces and collectively define a central handle grip. The inner annular handle is freely rotatable clockwise and counterclockwise about a center axis of rotation relative to the outer annular handle portion, and the inner annular handle portion rotates with the outer annular handle portion collectively relative to the arch. The hand grip has a plurality of fasteners connecting the arch to the outer annular handle, one each of the plurality of fasteners seated in a bore hole of the arch and connected to a mount of the outer annular handle portion. The front annular grip portion and the back annular grip portion define an annular seat for the annular roller bearing.
In all embodiments, the annular roller bearing has an inner race, an outer race, a bearing cage, and a plurality of bearings. The inner race is seated on the annular seat defined by the front and back annular grip portions.
Many aspects of the disclosure can be better understood with reference to the following drawings. The components in the drawings are not necessarily to scale, emphasis instead being placed upon clearly illustrating the principles of the present system.
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.

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 (AR) 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.
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.

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.
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.
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.
