Description
BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to the field of exercise equipment, and, in particular, to an adjustable exercise apparatus for increasing an individual's strength, agility and balance as well as for providing a cardiovascular workout.

[0003] 2. Background Art

[0004] There are many different activities in daily life which require individuals to use their strength, agility and balance. Furthermore, many of today's sports require even more developed abilities. In order to improve upon the skills needed for these activities many people have turned to various forms of exercise equipment designed to isolate and target the areas of the body used in these activities.

[0005] The initial movement in this area of exercise equipment led to the design of several different apparatuses concentrated on balancing. Similar designs have also been developed in the area of physical therapy. Several relevant patents in this area are: U.S. Pat. Nos. 5,522,783 and 5,667,462 to Gordon, U.S. Pat. No. 5,062,629 to Vaughan and U.S. Pat. No. 4,905,994 to Hartz. While many of these designs promote the development of the user's muscles and abilities, the extent of such development is eventually limited to the basic design of the board. Not only is there a limit to the amount of improvement which can be achieved, but eventual lack of further challenge often results in a lack of interest of the user.

[0006] What is needed is an exercise apparatus which allows for adjustment in the level of difficulty, as well as optional involvement of other areas of the body, for a total body workout.

BRIEF SUMMARY OF THE INVENTION

[0007] The present invention provides an exercise apparatus having a base, a platform with notches placed along its perimeter, and a resilient member located between the base and the platform. The exercise apparatus allows rotation about at least two axes of rotation. In an alternate embodiment of the invention, the resilient member may be modified by the attachment of a collar. The apparatus may also have a non-slip surface disposed on the top of the platform. Both the platform and the base may have support members disposed on their respective bottom surfaces to add support and stability and furthermore these support members may form a grid-like pattern. Also the resilient member may have both cavities and flanges to provide twisting and bending functionality as well as support to the exercise apparatus.

DETAILED DESCRIPTION OF THE INVENTION

[0021] Referring to the drawings, FIG. 1 shows a top perspective view of an exercise apparatus 100 of the present invention, in which a platform 102 is disposed above a base 104. In one embodiment, platform 102 and base 104 are composed of an aluminum honeycomb material, thereby making apparatus 100 light-weight and strong. In this embodiment a composite is formed from a aluminum honeycomb core laminated on both sides with sheet aluminum through a process of heat and pressure.

[0022] In another embodiment, platform 102 is molded of a high strength plastic material. Alternatively, platform 102 can be formed from a fiberglass core with a Kevlar skin, or from carbon fiber. As shown in FIG. 2, platform 102 can be formed to include support members 208 on a bottom surface of platform 102. Platform support members 208, in one embodiment, are downwardly projecting extensions on the bottom surface of platform 102, which form a grid-like pattern. It would be apparent to one skilled in the relevant art that other support structures could also be used to provide added stability and rigidity to platform 102.

[0023] Similarly, base 104 can also be molded from a high strength plastic or similar materials as platform 102. Base 104 can further be formed with base support members 210 on a bottom surface of base 104. Base support members 210, in one embodiment, are downwardly projecting extensions on the bottom surface of base 104, which form a grid-like pattern. It would be apparent to one skilled in the relevant art that other support structures could also be used to provide added stability and rigidity to base 104.

[0024]FIG. 2 shows a cross-sectional view of apparatus 100, in which a resilient member 202 connects platform 102 to base 104. A resilient member platform plate 204, preferably made from steel, is located between resilient member 202 and platform 102 and is used to attach resilient member 202 to platform 102 using bolts (not shown) or other attachment mechanisms, as would be apparent to one skilled in the relevant art. A resilient member base plate 206, also preferably made from steel, is located between resilient member 202 and base 104 and is also used to attach resilient member 202 to base 104. Resilient member platform plate 204 and resilient member base plate 206 also assist in weight distribution of the user from the platform 104 through the resilient member 202 and then onto base 104. In one embodiment, resilient member 202 is composed of a natural rubber material having a maximum static load of 770 lbs. and a spring rate of 850 lbs./in. while in shear and a maximum static load of 3870 lbs. and a spring rate of 5100 lbs./in. while in compression. Such a resilient member 202 is available commercially from the Lord Corporation as Part No. J14056-4 and can be composed of an elastomer. In one embodiment, the elastomer is a self-lubricating elastomer. In another embodiment, the elastomer is a self-lubricating, natural rubber. However, it would be apparent to one skilled in the relevant art that any of a variety of materials could be used to construct resilient member 202 such that resilient member 202 is capable of twisting about its vertical axis and bending along all directions of its horizontal axis. Resilient member 202 will be discussed in further detail below.

[0025] Platform 102 is shown in further detail in FIGS. 3-5. Notches 106 are located around the perimeter of platform 102. Notches 106 allow a user to attach rope or rubber hosing to apparatus 100 so as to permit the inclusion of arm movements into the exercise performed on the apparatus. In one embodiment, notches 106 are shaped as a key hole in order to hold a rope, elastic resistance tubing, or the like in position during use of apparatus 100. It would be apparent to one skilled in the relevant art that other shapes, such as “L”-shaped slots, could be used for notches 106. In still a further embodiment, a rope or tubing or the like could be attached, either removably or permanently, to the apparatus, and the notches 106 could be used simply as guides. Still further, handles could be attached to the ends of the rope or tubing. Also, a mechanism could be attached to the apparatus to retract the rope or tubing when not in use.

[0026] Platform 102 includes platform bolt holes 204 to attach platform 102 to resilient member 202. A cover recess 306 is located at the center of the platform 102 and allows for a cover (not shown) to be attached to platform 102 to provide a flat surface unaffected by the attachment bolts. Cover plate bolt holes 308 are used to attach the cover to platform 102. In one embodiment, upper surface 402 of platform 102 is constructed from a non-skid elastomeric material. In another embodiment a non-slip material, such as an elastomeric material, is stretched across upper surface 402 of platform 102. In another embodiment, a non-slip material is inlaid into a recess formed on the upper surface 402 of platform 102. In still another embodiment, the non-slip material is glued onto upper surface 402 of platform 102. It would be apparent to one skilled in the art that various coverings could be placed over upper surface 402 of platform 102 to alter both its texture and appearance. As discussed above, a rigid grid-like structure is formed by support members 208 on a lower surface 404 of platform 102, as visible in FIGS. 4 and 5.

[0027]FIGS. 6A, 6B, 7, 8A and 8B show one embodiment of resilient member 202. A top view of resilient member 202 shows resilient member pin holes 602 which align with platform pins 212 to provide proper alignment of resilient member 202 to platform 102. Resilient member 202 also has resilient member bolt holes 604 formed therein to allow attachment of resilient member 202 to platform 102 by bolts (not shown). Ridges 606 are provided around the outer perimeter of a top portion of resilient member 202 to connect resilient member 202 to platform 102 so that the twisting resistance provided by resilient member 202 can be evenly transferred to platform 102 and to prevent slippage. Resilient member pins 214 are used to help lock (attach) resilient member 202 to base 104.

[0028] Resilient member 202 has a cavity 704 and cut outs 706 formed therein to allow sufficient twisting and bending in accordance with the exercise being performed. It would be apparent to one skilled in the art that the size and shape of cavity 704 and/or cut outs 706 could be modified to produce different twisting and bending properties of resilient member 202. In another embodiment, resilient member 202 could be made as a solid piece of material. Flanges 802 are provided on a bottom surface of resilient member 202 to provide added support to resilient member 202.

[0029]FIGS. 9 and 10 show more detailed views of base 104. A base bottom surface 902 has base pin holes 904 formed therein for receiving resilient member pins 214 therein. Base bottom surface 902 or a ground-contacting perimeter thereon may be comprised of or coated with a material to prevent slippage of apparatus 100 during use. In another embodiment, base 104 may contain holes for securely attaching or bolting apparatus 100 to a ground surface. Resilient member base plate 206 is attached to a base top surface 1002 of base 104. In another embodiment, base 104 is comprised of legs (not shown) extending out from a central structure where resilient member 202 is attached. As discussed above, a rigid grid-like structure is formed by support members 210 on a lower surface 1004 of base 104, as visible in FIGS. 9 and 10.

[0030]FIG. 11 shows a front plan view of an alternate embodiment of a resilient member component 1100 comprising a resilient member 1102, a collar 1104, a resilient member platform plate 1106 and a resilient member base plate 1108. In this embodiment, resilient member 1102 has a groove 1110 around its center portion which allows collar 1104 to be placed around the resilient member 1102.

[0031] In one example, resilient member 1102 is a natural rubber cylinder with a diameter of 2 ⅞ inches. In one embodiment, groove 1110 has an outside height of 1 ¼ inches, and an inside height of ¾ inches, with a ¾ inch radius. Resilient member 1102 can be made of any of a variety of materials, as discussed above with respect to resilient member 202. The dimensions of the cylinder of resilient member 1102 will vary depending on the material used to construct resilient member 1102.

[0032] Collar 1104 may be comprised of an elastomer or polymer of various resiliency. One example of a material for collar 1104 is a material containing polytetrafluoroethylene (PTFE), such as Teflon, Fluoron or nylon. Alternately, collar 1104 can be made of any variety of other materials, as would be apparent to one skilled in the art. The addition of collar 1104 allows the user to control the degree of difficulty of use of the apparatus. In one embodiment, the material used for collar 1104 is more rigid than the material used for resilient member 1102. In another embodiment, the material used for collar 1104 is less rigid than the material used for resilient member 1102. Collar 1104 can be removable and replaceable such that overall resistance of resilient member 1102 may be modified depending on the relative resiliency of collar 1104. For example, collar 1104 may be hinged on one side with a bolt or clamp on the other allowing it to be opened, placed around groove 1110 of resilient member 1102 and then closed and secured in place. Alternatively, collar 1104 may be comprised of two separate pieces with flanges such that the two can be secured together around groove 1110 of resilient member 1102 with bolts. Other attachment means would be apparent to one skilled in the relevant art. In an alternate embodiment, collar 1104 could be cast in place, if it were intended to be permanently attached to resilient member 1102. When in place, collar 1004 bends and twists along with resilient member 1102.

[0033] Examples of Use

[0034] There are several different levels of exercise which can be achieved with apparatus 100. Such differing levels of workout or rehabilitation are achieved both through modification of the resistance levels of the apparatus 100 as well as the actual movements performed in coordination with the apparatus 100.

[0035] Strength and flexibility training can be achieved through a yoga-inspired workout which combines integrated muscle conditioning exercises and flexibility training. These exercises are designed to develop strength, flexibility, balance, stability and mobility. A user may be either standing or lying on the apparatus during this mode of exercise and must maintain balance while performing controlled stretching movements.

[0036] Interval training can be achieved through work efforts combined to be performed at intense levels. These interval exercises develop overall fitness and muscular endurance as well as improve balance and agility. A user may be either standing or lying on the apparatus during this mode of exercise and must maintain balance while performing repetitive movements over intervals.

[0037] Sports training can be achieved through a series of athletic circuits and muscle conditioning exercises that will push performance. Sports drills from football, basketball, tennis, baseball and boxing are combined with the integrated strength training to develop overall fitness, muscle strength and endurance as well as balance, stability, agility and mobility. A user may be either standing or lying on the apparatus during this mode of exercise and must maintain balance while performing movements specifically designed to mimic those of various sports activities.

[0038] The apparatus 100 can also be used to develop a specific exercise program to meet the individual needs of a specific user. New exercises can be introduced as required by different individuals and sports activities.

[0039] While the invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
