Multi-Orientation Nesting Grip Training Handle

Many sport and life activities require a strong grip or finger strength, especially climbing, obstacle racing, weight training, and martial arts. An increase in finger strength will improve overall performance and decrease the chances for injuries like tennis elbow and carpal tunnel syndrome.

One simple way to train grip strength is to perform regular exercises such as pull-ups and weight lifting using handles with an enlarged diameter, which increases the gripping difficulty and allows for grip training at the same time as exercising other muscle groups.

A second simple way to train grip strength is to orient the handle such that the direction of the handle is parallel to the direction of the load. It requires much more grip force to perform exercises in this orientation.

Athletes looking to train their grip strength would find it desirable to have a small, portable handle that allows them to train their grip strength by varying both the diameter of the handle and its orientation. Going from a small diameter, to an intermediate diameter, and then to a large diameter, with incrementally increasing difficulty allows these athletes to train their grip strength progressively.

The multi-orientation nesting grip training handle of the present invention allows for the training of grip strength by providing 3 different handle diameters—small, medium and large, with the smallest being easiest to grip and the largest being most difficult to grip, and also providing 2 different handle orientations—horizontal and vertical—in each of the 3 diameters (6 configurations in total). It does this while being small and compact, and without requiring the user to carry separate attachments for different exercises. This is accomplished by incorporating three different nesting handles of different diameters, the outer two of which can be removed or installed by the user, and a special rope and knot configuration that allows the handle to be used in either the horizontal or vertical orientation. This means that the user can, in a combination not offered by the prior art, carry the multi-orientation nesting grip training handle with them, adjust it to the diameter and orientation they want, and exercise either by securing the handle to an appropriate anchor point and hanging from it, or by attaching it to a resistance machine, resistance band, bungee cord, or weight and pulling with the desired amount of force.

The multi-orientation nesting grip training handle can be used at home by using a portable opposably mounted pull up device (ex U.S. Pat. No. 10,252,099B2) to non-permanently secure it to a door frame during an exercise session. This combination is easy to carry around and mount at home, in a hotel, at work, or any other location that has a suitable door frame.

In the present invention, a number of configurations of angle and diameter are possible. This results in a large number of possible exercise difficulties depending on the angle and diameter chosen. The combination of the two adjustments can accommodate users of all different skill levels from beginner to expert, and it allows the user to progressively increase the difficulty level of their grip strength training.

The description that follows and the embodiments described therein are intended to clarify the nature and principles of the invention by means of examples. These examples are provided for the purposes of explanation, and not of limitation, of those principles and of the invention. In the description, similar parts are marked throughout the specification and the drawings with the same respective reference numerals.

Referring to, shown—from different angles and in different configurations-are two identical possible embodiments of the present invention, highlighting their essential constituents and the features through which they interact with external elements. The embodimentsshown each consist of three nesting handles,,; rope, and shims threaded chain link. The ropefeatures three knots-overhand knot, overhand knot, and fisherman's knot. Knotforms the rope into a loop. Knotacts as a jam knot and supports the load when the handle is in the vertical orientation. Knotallows the threaded chain link to be hooked up underneath it, allowing the handle to be secured in the vertical orientation. The innermost handlehas a hole that allows the ropeto be passed through, but which is small enough that the knotcannot pass through it. Note that although this particular embodiment shows three handles, this invention can be easily modified and adapted to incorporate a different number of handles, for example 2, which would reduce cost, or 4 or more, which could allow either a greater range of diameters or smaller diameter increments for the user. The handles can be manufactured by plastic injection molding, allowing them to be manufactured economically, although other manufacturing methods are possible. The handles can incorporate a grippy texture, or a separate grippy substance such as rubber or thermoplastic elastomer on their outer surface.

The chain linkcan be undone and removed, and the middle handleand outer handlecan be slid off the innermost handlein order to change the diameter of the handle. The bottom part ofshows the large holes at the top of the middle handleand outer handlethat allow the embodiment to be taken apart this way.

The cutaways inshow the same cutaways as, but with the inner, middle, and outer handles separated. This reveals the internal ribs of the middle handleand outer handle, which serve to add stiffness and reduce the weight of the middle and outer handles. The diameters of the inner, middle, and outer handles are designed to span easy, moderate, and difficult grip exercises.

shows 6 possible configurations of this embodiment. By installing or removing the middle handleand outer handle, it is possible to have the handle in small, medium, and large diameters. By rearranging the configuration of the ropeand threaded chain link, it is possible to configure each diameter of this embodiment in horizontal and vertical orientations.
