ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to an exercise apparatus for use in a body of water. More particularly, it relates to a portable aquatic exercise apparatus used for strengthening abdominal muscles which mounts on the edge of a pool such that a person is supported in the pool by the apparatus while exercising, the apparatus capable of collapsing into a convenient size for easy transportation and storage when not in use.
2. Description of the Prior Art
Aquatic exercise devices used to strengthen muscles are known in the prior art. For instance, U.S. Pat. No. 5,033,735 to Erickson shows an aquatic exercise device removably attachable to a pool ladder or, in an alternate embodiment, permanently attachable to a pool deck. The device can be used to perform a bevy of different exercise routines including chin-ups, sit-ups, leg butterflys and leg kicking. Unfortunately, the Erickson device requires either exclusive use of the pool ladder or permanent pool deck attachment means to affect use thereof. If the ladder of the pool is needed, the Erickson device must be removed. Attempts at climbing the ladder with the device attached thereto could result in injury. An alternate embodiment of Erickson attempts to alleviate this problem by providing for permanent attachment to the pool deck. Unfortunately, not all pool owners want a device permanently affixed to the deck of their pool. Besides detracting from the aesthetic appearance of the pool, the permanently mounted device could cause injury if tripped upon. An improved aquatic exercising device is needed which can overcome the deficiencies seen in the prior art. Such a device should be portable, should not require the use of a ladder or other means of attachment and should further provide for easy transportation and storage thereof when not in use.
SUMMARY OF THE INVENTION
I have invented an improved aquatic exercising apparatus which can be used to strengthen abdominal muscles. My apparatus does not require a permanent means of attachment nor the use of other pool accessories (i.e., ladder or steps) for affecting the use thereof. My apparatus conveniently rests upon the side and deck of the pool. Further, my apparatus is lightweight, portable and collapsible, providing for easy transportation and storage.
The apparatus includes a pair of downwardly extending legs which parallel the side of the pool when the apparatus is set therein. A pair of inwardly extending feet are positioned on a lower end of the pair of legs for resting upon the side of the pool. Positioned at a middle portion of the pair of legs are a pair of couplers to which a pair of four-way coupling units are mounted. Each four-way coupler has four openings formed therein. Two of the openings, which are axial alignment of one another retain the coupler in a fixed position. A third opening of each coupler receives one of a pair of outwardly extending arm-rests. A fourth opening of each coupler receives one end of a back-rest support rod. A pair of deck-resting members, integrally attached to an upper end of each leg at a ninety degree therefrom, work in conjunction with the pair of feet to position the apparatus in a fixed position along the side of the pool. A back rest, in parallel relationship with the side of the pool, is supported by the back rest support rod.
The arm-rest extensions are removable and the legs are pivotable within the coupler providing a means to collapse the apparatus (see FIG.
2
). The arm-rests, the deck-resting members and the legs are telescopic permitting the apparatus to be adjusted for a variety of different people and configuration of pools.
