The present disclosure generally relates to exercise devices. More particularly, the present disclosure relates to an exercise platform that provides for omnidirectional movement of the platform while performing various exercises.
Over the years physical exercise has grown in popularity to improve the health and physical appearance of a person and also to reduce stress. There are a many forms of physical exercise that may be employed by a person such as: strength training, aerobics, calisthenics, and plyometrics to name a few. A common strength training exercise is the traditional push-up. In performing a push-up, a user assumes a prone position, and lifts the body using the arms. Through this exercise, the weight of the body serves as the main source of resistance to the muscles, particularly the pectoralis muscles, which are used in performing the push-up. However, greater muscle training efficiency may be obtained by activating additional muscle groups while performing the push-up. This is accomplished by modifying the standard up-down motion of the push-up to include various secondary movements such as: leg raises, one-armed push-ups, various hand positions, hip raises and the like. By using such modifications, the user activates various secondary muscle groups, which in turn significantly increase the effectiveness of the physical exercise.
Additionally, exercise efficiency can be further enhanced by random activation of these secondary muscle groups, which induces muscle confusion. It is known that performing the same exercise over and over cause the human body to adapt to these exercise motions and thereby causing a diminishing return by performing the same exercise repeatedly. Consequently, by employing muscle confusion that randomly activates various secondary muscle groups during a particular exercise, the human body is less likely to adapt to the exercise motions and thus receives greater benefit from the exercise.
There are several known devices in the prior art that seek to enhance the overall effectiveness of performing various exercises and in particular the traditional push-up. These devices commonly seek to facilitate one or more secondary motions, which in turn activate additional muscle groups during the core exercise. One known solution provides a platform having base member and a handle member that rotate with respect to each other along a vertical axis. The base member has a non-slip surface that engages a floor surface and prevents the device sliding along the floor. While this known solution is somewhat useful, it presents substantial drawbacks. Firstly, this device only permits the handle member to rotate which in turn allows the arms of a user to twist during the push-up. Although this does engage some secondary muscle groups, this rotation of the hand position generally focuses on the smaller muscles of the forearm and upper arm. Secondly, this device does not permit lateral motion of the device along the floor surface and thereby fails to activate many secondary muscle groups in the shoulders, chest, and back of a person during the exercise motion.
Another known solution provides an exercising device that includes a platform and a number of peripherally spaced caster wheels underneath the platform, for supporting a limb of a user on or against a supporting surface while permitting movement of the limb in any direction along the supporting surface. The platform has a lower body part that carries the caster wheels, and a removable upper part, which can be removed or inverted to change the configuration of the upper surface of the platform. Straps are provided to secure the device to the limb of a user. While this known solution is somewhat useful, it presents substantial drawbacks. To begin, the device uses a plurality of caster wheels that must be pushed or pulled to orientate each caster in the same direction. Then when a directional change is desired, the user must apply additional force to get the plurality of casters change direction and align in the new direction. This additional force requirement induces an inconsistency in the exercise motion. Further, this device does not facilitate a smooth uniform exercise motion because the multiple casters must realign prior to changing direction. Next, this device employs casters having a wheel/ball member that is supported by thru axel coupled to the frame of the caster. This configuration is likely to have increased axle friction under load and thus does not facilitate free motion.
Various exercise devices are known that employ a plurality of ball and cup-type members coupled to a bottom surface of the device and while somewhat useful these known solutions present substantial drawbacks. In these known solutions, there is generally provided a plurality of ball members that are rotationally coupled into a hemispherical cup formed within a housing member. The ball members are free to rotate in any direction with respect to the hemispherical cup. These known solutions, while providing some benefit, have a substantial drawback of increased friction between the ball member and hemispherical cup under load conditions. This type of ball motion assembly has a substantial portion of the ball member surface area in sliding contact with the surface area of the hemispherical cup and thereby restricts the free motion of the ball with respect to the cup under load. Moreover, in these known solutions, as a user increases the load on the device the induced additional friction between the ball and cup prevent the fluid multi-directional movement of the exercise device.
In another known exercise device that provides a hemispherical support frame and a single rigid support ball mounted to the support frame with a plurality of smaller low-friction ball bearings disposed in between the support ball and the support frame such that the support ball is freely rotatable in any direction. While this known solution is somewhat useful, it presents substantial drawbacks. Most significantly, this device only provides a single support ball, which causes the hemispherical support frame to be unstable during use. As discussed above, having and exercise device that permits a user to activate secondary muscle groups is advantageous. However, the exercise device must provide a stable platform by which the exercise can be safely performed and which reduces the possibility of injuring the user. Although this known exercise device provides a platform that facilitates fluid multi-directional movement during use, this device inherently presents an increased risk of potential injury to the user. The device has a high center of rotation between the support ball and hemispherical support frame. During use, this high center of rotation is likely to cause an undesired change in direction, due to the instability of the device, which may injure the hand, wrist, foot, or ankle of a user. For example, during a push-up it is beneficial to have the freedom of motion to laterally translate the hand position of the user (i.e., left/right/fore/aft) with respect to the starting position of the hands. It is also beneficial to have the freedom of rotational movement with respect to a vertical axis normal to a supporting floor surface. However, this known device permits a freedom of rotational movement with respect to a horizontal axis parallel to the supporting floor surface. This horizontal freedom of movement causes a twisting/torquing of the wrist joint of the user, which in turn is likely to result in a significant and painful injury to the user. In another example, this known device may be used for hamstring raises where the user places their feet on the hemispherical support frame to exercise their hips, hamstrings and core. As discussed above, this known solution presents a similar risk of injury to the ankle of the user, due to the horizontal freedom of movement, which can induce an undesired twisting/torquing of the ankle joint.
Efforts to provide an omnidirectional exercise platform that overcomes the drawbacks in the prior art have not met with significant success to date. As a result, there is a need in the art for an exercise platform that provides smooth, fluid omnidirectional movement of the platform and concurrently provides a stable platform that reduces the risk of injuring the user.
The basic inventive concept provides an omnidirectional exercise platform that permits free multi-directional translation of the platform with respect to a support surface, and further permits rotational movement with respect to a vertical axis normal to the support.
From an apparatus aspect, the invention comprises an omnidirectional exercise platform for facilitating a physical training exercise. The platform includes a base member having a top surface, an opposing bottom surface and at least one sidewall disposed there between. A plurality of apertures is formed into the bottom surface of the base member and extending towards the top surface of the base member. A pad member having a top surface, an opposing bottom surface and at least one sidewall disposed there between is coupled to the top surface of the base member. Each individual ball transfer unit is coupled within one of the plurality of apertures formed into the bottom surface of the base member, such that the plurality of ball transfer units substantially reduces rolling resistance when the omnidirectional exercise platform is loaded over a support surface during the physical training exercise.
From a system aspect, an omnidirectional exercise system is disclosed comprising a pair of omnidirectional exercise platforms for facilitating a physical training exercise. Each platform includes a base member having a top surface, an opposing bottom surface and at least one sidewall disposed there between. A plurality of apertures is formed into the bottom surface of the base member and extending towards the top surface of the base member. A pad member having a top surface, an opposing bottom surface and at least one sidewall disposed there between is coupled to the top surface of the base member. Each individual ball transfer unit is coupled within one of the plurality of apertures formed into the bottom surface of the base member, such that the plurality of ball transfer units substantially reduces rolling resistance when the omnidirectional exercise platform is loaded over a support surface during the physical training exercise.
From a method aspect, a method of fabricating an omnidirectional exercise platform for facilitating a physical training exercise, comprising the steps of: providing a base member having a top surface, an opposing bottom surface and at least one sidewall disposed there between; forming a plurality of apertures into the bottom surface of the base member and extending towards the top surface of the base member; coupling a pad member to the top surface of the base member, the pad member having a top surface, an opposing bottom surface and at least one sidewall disposed there between; and coupling each individual ball transfer unit of a plurality of ball transfer units within one of the plurality of apertures formed into the bottom surface of the base member, wherein the plurality of ball transfer units substantially reduces rolling resistance when the omnidirectional exercise platform is loaded over a support surface during the physical training exercise.

A cross-sectional view of the omnidirectional exercise platform 100 is illustrated in
The ball transfer unit 130 configuration disclosed herein permits rapid omnidirectional movement of the primary ball member 133 with significantly reduced friction under high load conditions. The reduced friction and smooth omnidirectional movement provided by ball transfer unit 130 is enabled by reducing the contact surface area between the primary ball member 130 and the concave inner surface of housing 131. The reduction of this dynamic surface contact area is primarily effectuated by employing a plurality of secondary ball members 134 which provide both a load path and dynamic moving contact point between the primary ball member 130 and the concave inner surface of housing 131.
In one exemplary embodiment, housing 131 is configured with one or more apertures 220 formed there through. The size and location of apertures 220 may vary depending on the style of ball transfer unit 130 employed. Aperture 220 provides a means for cleaning and maintaining the ball transfer unit 130 and thereby extending the operational lifespan of the ball transfer unit 130. In one embodiment, aperture 220 may be sized such that internal contaminants such as dust, dirt, lint, fibers, fluid and the like may be permitted to pass through aperture 220 and out of housing 131. In this embodiment, aperture 220 may be sized slightly smaller that secondary ball members 134 but large enough to provide access to the inner surface of housing 131 to thereby facilitate cleaning and lubricating procedures.
Both the housing 131 and retention member 132 may be fabricated from various structural materials capable of providing adequate performance for a given load range. In one exemplary embodiment, housing 131 and retention member 132 are fabricated from stainless steel. Alternatively, housing 131 and retention member 132 may be fabricated from a zinc plated metal sheet. It is contemplated that primary and secondary ball members 133, 134 be precision ground and heat-treated such that surface imperfections and friction between the ball members are minimized. Retention ring 135, in one embodiment, is fabricated from polymer having high lubricity characteristics such as DELRIN® which is a well-known material used in component manufacturing. However, there are many suitable materials that may be employed and one of ordinary skill in the art would readily understand the various material substitutions.
In one exemplary embodiment the primary ball member 133 and/or secondary ball members 134 may be fabricated from various materials such as stainless steel, metal alloys, Teflon, nylon, polymers, composites, ceramics or combinations thereof. It is contemplated that that primary ball member 133 may be selected from a material that prevents adversely marking, scuffing or scratching a floor support surface such as hardwood or tile.

Directing attention to
It is understood that the omnidirectional exercise platform 100 can enable the user to complete any of a variety of additional exercises.
As will be now apparent to those skilled in the art, omnidirectional exercise platform fabricated according to the teachings of the present invention are capable of substantially enhancing one or more physical exercises of a person. Since the present invention provides an omnidirectional exercise platform that permits free multi-directional translation of the platform with respect to a support surface while performing an exercise and correspondingly requires the user to activate secondary muscle groups to prevent undesired movement of the omnidirectional exercise platform. In addition, the invention provides a platform that further permits rotational movement with respect to a vertical axis normal to the support surface. Importantly, the present invention provides a stable platform that reduces the risk of injuring the various joints (e.g., wrists & ankles) of the user. Specifically, with the present invention, it is possible to perform various physical exercises that engage a multitude of secondary muscle groups while simultaneously providing a stable surface that substantially prevents undesired twisting/torquing of delicate joints of the user. Finally, the invention provides a device that may be adapted by a user to employ different handgrip positions during an exercise.
Although the above provides a full and complete disclosure of the preferred embodiments of the invention, various modifications, combinations, alternate constructions and equivalents will occur to those skilled in the art. For example, although the invention has been described with reference to coupling the padded member to the base member, alternatively the padded member may be configured for easy removal to facilitate cleaning/replacement. Further, the invention has been described with reference to using individual ball transfer units that are coupled to the base member, these components may be permanently coupled or integrally formed therewith. It is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Therefore the above should not be construed as limiting the invention, which is defined by the appended claims and their legal equivalence.
