BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to an exercise device that utilizes a plurality of sliding and pivoting motions for the purpose of exercising various muscles, such as the abdominal muscles.
2. Description of Related Art
Various exercising equipment and equipment free methods of exercising have been developed for exercising the abdominal muscles. Abdominal muscles are generally difficult to isolate and strengthen. Many hours and years of exercise are generally necessary to produce a significant effect on the abdominal musculature. Exercising these muscles may create strain and pressure on the back and neck muscles, depending on the technique used. Additionally, failure to maintain consistent and proper alignment while exercising the abdominal muscles may result in an ineffective workout as well as injury.
Generally, exercise devices are known in the art that provide a framework for individuals to extend their upper torsos from a kneeling position to a prone position in order to strengthen and stretch various muscle groups of the upper torso. A typical apparatus would include a sliding member that could be propelled along a sliding surface by the user stretching the user's body from a kneeling to a prone position, and vice-versa.
Known exercise devices are limited in several respects. For example, prior art devices did not provide adjustable resistance by elevating a track on which the sliding member maneuvered. Additionally, such prior devices were not adaptable to provide an exercise regime particularly and individually directed to the muscles groups of the arms, chest, or legs. Generally these devices are limited in that they include a single track with which the user stretches back and forth. Thus, only a certain set of muscles are isolated for strengthening and performance.
What is needed is a push-pull type exercise device that overcomes the above shortcomings. The invention should permit a large number of body parts to be exercised. Furthermore, the exercise device should be comfortable.
BRIEF SUMMARY OF THE INVENTION
The exercise device in accordance with the present invention includes an elevated base that diverges forwardly into a plurality of elevated arms. The elevated base has a single track disposed thereon and each of the elevated arms includes an elongated track member disposed between opposing first and second ends such that said first end is proximal to a forward end of the single track provided on the elevated base. An elevated beam protrudes rearwardly from the elevated base. The elevated beam has a stationary knee support provided thereon. A single slider including a steering mechanism is slidably disposed on the single track and selectively onto an elongated track member of any one of the plurality of elevated arms. Preferably, a plurality of legs are used to elevate the plurality of elevated arms, elevated base and elevated beam from a surface by a distance of at least three inches.
The present exercise device mostly works the abdominal and oblique muscles in addition to chest, back, gluteus, triceps and shoulders. The exercise device is preferably designed with three elevated arms including three elongated track members. In a preferred embodiment, the exercise device is elevated above the surface approximately 12-20 inches and is supported by 5-6 legs.
Generally, the present exercise device utilizes a person's own body weight and strength to perform the exercises. In a knee bent position, the user rolls the single slider forward and backward between the single track and the selected elongated track member. The present exercise device keeps abdominal and other body muscles firm and in shape.

DETAILED DESCRIPTION OF THE INVENTION
FIGS. 1-6 shows an exercise device 10 in accordance with one embodiment of the present invention including a plurality of elevated arms 12, 14, 16 diverging forwardly from an elevated base 18. The elevated base has a single track disposed thereon and each of the elevated arms 12, 14, 16 includes an elongated track member disposed between opposing first and second ends such that the first end is proximal to a forward end of the single track provided on the elevated base 18. While FIGS. 1-6 show a preferred embodiment of the present invention including three elevated arms 12, 14, 16, it will be understood by those of skill in the art that two or more elevated arms may be provided in accordance with the present invention. An elevated beam 20 protrudes rearwardly from the elevated base 18 and includes a stationary knee support 22 provided thereon. It should be understood to those of skill in the art that the elevated base 18 may be continuous with the elevated beam 20 such that there is no discernable separation of the elevated base 18 and the elevated beam 20. As provided in FIGS. 1-6, the elevated base 18 is the forward end of the elevated beam 20. The plurality of elevated arms, elevated base and elevated beam are preferably supported using a plurality of legs 24, 26, 28, 30, 32, 34. It will be understood to those of skill in the art that the plurality of legs 24, 26, 28, 30, 32, 34 may be extendable such that the length of the legs may be adjusted to alter the height of the exercise device 10 from a supporting surface (e.g. the ground). Additionally, the plurality of elevated arms 12, 14, 16 may be supported on extendable legs proximal to the second end of each elongated track member to provide for an incline and/or decline to the elongated track member. A single slider 36 including a steering mechanism 38 is slidably disposed on the single track and selectively onto an elongated track member of any of the plurality of elevated arms 12, 14, 16. The steering mechanism 38, such as a handle, allows the user to guide the slider 36 to a selected elongated track member. The terms “slider” and “slidably” are used generally as providing for smooth movement along a surface in continual contact with it including, but not limited to, u-shaped roller and other bearings. FIG. 1 shows one embodiment of the present invention wherein the elongated track member includes a channel for receiving a wheel member, or other protuberance, from the single slider 36 for selectively sliding the single slider 36 along the length of the elongated track from the first end to/from the second end of any one of the plurality of elevated arms 12, 14, 16. FIG. 1 also provides a bench 40 as an optional component to be provided to the exercise device 10 on which the user may sit to rest.
FIGS. 7-9 shows an exercise device 110 in accordance with another embodiment of the present invention including a plurality of elevated arms 112, 114, 116 diverging forwardly form an elevated base 118. The elevated base 118 has a single track disposed thereon and each of the elevated arms 112, 114, 116 each includes an elongated track member disposed between opposing first and second ends such that the first end is proximal to a forward end of the single track provided on the elevated base 118. An elevated beam 120 protrudes rearwardly from the elevated base 118 and includes a stationary knee support 122 provided thereon. As seen in this embodiment, the elevated base 118 is continuous with the elevated beam 120 such that there is no discernable separation of the elevated base 118 and the elevated beam 120. The plurality of elevated arms, elevated base and elevated beam are preferably supported by a plurality of legs 124, 126, 128, 130, 132, 134. It is understood that more or less legs may be provided depending on the stability required for the exercise device 10, 110. Also, it should be understood to those of skill in the art that the plurality of legs 124, 126, 128, 130, 132, 134 may be extendable. Additionally, the plurality of elevated arms 112, 114, 116 may be supported on extendable legs proximal the second end of each elongated track member to provide for an incline and/or decline to the elongated track member. A single slider 136 including a steering mechanism 138 is slidably disposed on the single track and selectively onto an elongated track member of any of the plurality of elevated arms 112, 114, 116. In this embodiment, the exercise device 110 includes a single slider 136 having one roller bearing on the top of the single track and/or elongated track member with four other bearings on the underside thereof. The steering mechanism 138 allows the user to guide the single slider 136 to a selected elongated track member. FIG. 10 shows one embodiment of the present invention wherein the single track and each of the elongated track members includes an elongated post member to be received within a recess provided in the single slider 136 for selectively sliding the single slider 136 from the single track along the length of the elongated track to/from the first and second end of any one of the elongated track members. In this preferred embodiment, each of the elongated post members has the same, or substantially the same, cross-sectional area in order to slidably fit within the recess provided by the single slider 136. Also, in this embodiment, the elongated track members are not continuous with the single track. However, in this embodiment, the single track is provided such that it extends forwardly toward the first end of each of the elongated track members such that said single slider may be smoothly conveyed from said single track to any of said elongated track members. In the embodiment provided in FIG. 10, the single track is provided on a swivel platform 142 pivotally connected to the elevated base 118 at pivot point 144. The pivot point 144 allows the single slider 136 to be steered into any one of the elongated track members on the plurality of elevated arms 112, 114, 116. In this embodiment, the swivel platform 142 rests on a spring loaded bearing that the single slider 136 falls into so that the single track is firmly retained in a position adjacent to the first end of a selected elevated track member.
Preferably, the only moving element during use of the exercise device 10, 110 is the single slider 36, 136. However, the legs may be extended prior/after use to adjust the height of the exercise device from the support surface. In one embodiment, the legs are extended such that the plurality of elevated arms, elevated base and elevated beam are supported by a distance of at least three inches from a support surface (e.g. floor or ground), more preferably a distance of 12-20 inches from the support surface. In a preferred embodiment including three elevated arms, 5-6 legs are used to support the elevated arms, elevated base and elevated beam. It is also possible to adjust the position of the stationary knee support 22, 122 before/after use of the exercise device. However, it is preferred that the stationary knee support 22, 122 does not move during the use of the exercise device.
Optionally ancillary devices may be attached to the exercise device 10, 110 to provide ease of use and/or improved performance. For example, an Achilles support may outwardly extend from the raised beam 20, 120 near the leg 24, 124. Also, a waist strap may be suspended from a member extending upwardly from the raised beam 20, 120 near the leg 24, 124 such that it extends over the stationary knee support 22, 122. Furthermore, resistance bands may be connected to the single slider 36, 136 along any one of the elongated track members, or each elongated track member. In a preferred embodiment, the steering mechanism 38, 138 may include a miniature finger or thumb brake.
