## Title
Convex push-up handles

## Abstract

A device for assisting a user in performing push-up exercises on a floor surface is disclosed. The device includes at least one rigid shell that has a convex outer surface and a concave inner surface. Each surface is mutually connected by a peripheral edge that defines a shell opening. A means for handling is fixed with the concave inner surface within each shell and is adapted to be grasped by the user. Preferably a pair of such shells are adapted to mechanically, selectively and mutually attach at the peripheral edges thereof to form a container thereby. In use, the user grasps the means for handling of each of the shells with either hand and perform exercises on the floor surface by pressing each shell against the floor surface. The convex outer surface requires the user to continuously stabilize the device on the floor surface, thereby exercising muscles not normally exercised while performing the exercises.

FIELD OF THE INVENTION
This invention relates to exercise devices, and more particularly to unstable push-up handles.
DISCUSSION OF RELATED ART
So-called “push-up handles” have become popular for assisting a user in keeping his arms properly positioned while doing “push-up” exercises on a floor surface. Typically such push-up handles provide a means for handling for allowing the user to grasp the handle while doing push-ups, as opposed to the traditional method wherein the user presses against the surface with his open palm, which puts considerably pressure on the user's wrist. Further, such prior art devices typically allow for the handle to rotate about a vertical axis.
Examples of typical prior-art push-up handles can be found in the following patents and patent applications:

Such prior art push-up handles suffer from the drawback that they are stable when on the floor surface, and as such the user does not have to stabilize such handles with muscles that are not otherwise exercised by such handles. As a result, using such handles prevents complete exercising of the arm, shoulder, back muscles, abs, etc.
An exercising weight disclosed in U.S. Pat. No. 6,709,371 to Wu includes a handle with a rounded outer surface. Such a device is not well-suited to use while doing push-up exercises because the handle is significantly above the center of gravity of such a device. As such, this type of product is too unstable to be easily used by a person performing push-ups. Further, a pair of such devices is not easily transported or stored, and makes no provision for containing other exercise implements such as a jump rope, or the like. Further, such a device is weighted, which is fine for people desiring to do weight-based exercises, but is a hindrance for user's wishing to do push-up exercises.
Therefore, there is a need for a device that provides push-up handles for engaging with a floor surface. Such a needed device would allow natural rotation and positioning of the wrists while performing push-up exercises therewith, but would also provide a convex contact surface with the floor so that additional muscles are exercised. The user of such a needed device would be able to establish any desired handle angle for added challenge. Such a needed device would not be so unstable as to be unusable, however, keeping the handles of such a device proximate to the center of gravity of the device. Further, such a needed device would be easily transported, handled, and stored, and would provide a container for holding other exercising implements such as a jump rope, or the user's wallet and keys, for example. The present invention accomplishes these objectives.
SUMMARY OF THE INVENTION
The present device is a device for assisting a user in performing exercises, such as pushups, on a floor surface. The device includes at least one rigid shell that has a convex outer surface and a concave inner surface. Each surface is mutually connected by a peripheral edge that defines a shell opening. A means for handling is fixed with the concave inner surface within each shell and is adapted to be grasped by the user. Preferably a pair of such shells are adapted to mechanically, selectively and mutually attach at the peripheral edges thereof to form a container thereby.
In use, the user may grasp the means for handling of each of the shells with either hand and perform exercises on the floor surface by pressing each shell against the floor surface. The convex outer surface requires the user to continuously stabilize the device on the floor surface, thereby exercising muscles not normally exercised while performing the exercises.
The present device provides push-up handles for engaging with a floor surface that allow rotation of the wrists while performing push-up exercises therewith, but that also provide a convex contact surface with the floor so that additional muscles are exercised. The present invention is not so unstable as to be unusable, however, in that means for handling of the present device are kept proximate to the center of gravity of the device. A user of the present invention is able to establish any desired handle angle for added challenge. Further, the present device is easily transported, handled, and stored, and provides a container for holding other exercising implements such as a jump rope, or the user's wallet and keys, for example. Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Illustrative embodiments of the invention are described below. The following explanation provides specific details for a thorough understanding of and enabling description for these embodiments. One skilled in the art will understand that the invention may be practiced without such details. In other instances, well-known structures and functions have not been shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.
Unless the context clearly requires otherwise, throughout the description and the claims, the words “comprise,” “comprising,” and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in the sense of “including, but not limited to.” Words using the singular or plural number also include the plural or singular number respectively. Additionally, the words “herein,” “above,” “below” and words of similar import, when used in this application, shall refer to this application as a whole and not to any particular portions of this application. When the claims use the word “or” in reference to a list of two or more items, that word covers all of the following interpretations of the word: any of the items in the list, all of the items in the list and any combination of the items in the list.
FIGS. 1 and 2 illustrate a device 10 for assisting a user 20 in performing exercises, such as push-ups, on a floor surface 30. The device 10 includes at least one rigid shell 40 that has a convex outer surface 48 and, preferably, a concave inner surface 42. Each surface 42,48 is mutually connected by a peripheral edge 45 that defines a shell opening 50. Each shell 40 is preferably made from a rigid plastic material, such as ABS, PVC, or the like. The outer surface 48 may also be coated with a high-friction coating, such as an elastomeric coating (not shown), or may be formed with a rough texture for providing a non-slip surface (not shown).
A means for handling 60 is fixed with each shell 40, such as on a top surface thereof (not shown), or preferably on the concave inner surface 42 therein in embodiments having the inner surface 42. In the preferred embodiment, each means for handling 60 is a bar-like structure adapted to be grasped by the user 20. In one embodiment of the invention, each means for handling 60 includes a resilient material 70 therearound for providing a comfortable grip 72 (FIG. 2), such as a closed cell foam or elastomeric material.
Preferably the at least one rigid shell 40 includes a pair of such shells 40 which are adapted to mechanically, selectively and mutually attach at the peripheral edges thereof to form a container 90 thereby (FIG. 4). Preferably each shell 40 is formed into a partial egg shape 80 (FIG. 2), such that the container 90 is generally spherical. Each shell 40 is mutually held to the other shell 40 by at least a pair of mechanical snaps 43, screw threads (not shown), or the like.
In one embodiment of the invention, each means for handling 60 is a rigid handle portion 65 that is selectively detachably connected to the concave inner surface 42 of the shell 40. Each handle portion 65 may include a tab 66 on each end thereof that mechanically cooperates with a slot arrangement 67 of each shell 40, or some other suitable mechanical fastening arrangement may be used. Preferably at least one tab 66 is non-circular (FIG. 3). Each means for handling 60 may further be ergonomically matched to the shape of a grasping human hand (not shown), and each shell 40 may include an indicia 100 for indicating use with either the left or right hand (FIG. 4), as determined by the ergonomically shape of each means for handling 60.
In one embodiment of the invention, each handle portion 65 may be selectively fixed to one end 115 of a jump rope 110. In this embodiment the jump rope 110 is completely storable within the container 90 when the shells 40 are mutually fixed together. Likewise, each handle portion 65 may be selectively fixed to one end 145 of a resistance member 140, such as a length of resilient elastomeric material. In this embodiment the resistance member 140 can be bent so that it is completely storable within the container 90 when the shells 40 are mutually fixed together. A flexible tether 120 may be further included, fixed around one of the means for handling 60, for facilitating the holding, transportation and storage of the device 10. Such a tether 120, when the shells 40 are mutually fixed together, traverses a tether notch 130 formed in the peripheral edge 35 of at least one of the shells 40 (FIG. 2).
In use, the user 20 may grasp the means for handling 60 and perform exercises on the floor surface 30 by pressing each shell 40 against the floor surface 30. The convex outer surface 48 requires the user to continuously stabilize the device 10 on the floor surface 30, thereby exercising muscles not normally exercised while performing the exercises.
While a particular form of the invention has been illustrated and described, it will be apparent that various modifications can be made without departing from the spirit and scope of the invention. For example, the shape of each pair of shells 40 is illustrated as spherical, yet the shells 40 may be made in various other shapes, including an oblong egg shape 80, or even irregular shapes (not shown). Accordingly, it is not intended that the invention be limited, except as by the appended claims.
