The present invention relates to an exercise device and associated methods for strengthening a user's hamstrings. The various components of the preferred embodiment of the present invention, and the manner in which they interrelate, are described in greater detail hereinafter.
In the embodiment depicted in FIGS. 1-6, the exercise device 10 comprises a body portion 12 for supporting a user. The body portion 12 may include a pair of adjacent forward-facing protrusions 14 defining an elongate slot 16, the function of which will be described in greater detail hereinafter. The device 10 may also include a user support rod 18 pivotally connected to the body portion 12 and adapted for pivoting into the elongate slot 16. In one embodiment, described in greater detail below, the device 10 also includes a leg support system 20 operably connected to the body portion 12 for engaging the legs of the user.
As illustrated in the embodiment depicted in FIGS. 1A-2, the body portion 12 is defined by an upper platform 22 having forward- and rearward-facing ends 22a, 22b. The forward-facing end 22a further comprises a pair of adjacent protrusions 14 defining an elongate forward-facing slot 16. The rearward-facing end 22b includes a pair of receivers 24, each receiver 24 having a pin 26 extending laterally therefrom. To provide comfort to the user, the upper platform 22 further comprises a knee pad 28 adapted for cushioning the weight of the user (See FIG. 3). As illustrated herein, the knee pad is substantially rectangular. Other shapes and configurations, however, are considered to be within the scope of the present disclosure, including the use of multiple pads to achieve the same result of cushioning the weight of the user.
With continued reference to the embodiment depicted in FIGS. 1A-2, the body portion includes a base portion 30 having forward- and rearward-facing ends 30a, 30b and an intermediate support region 32. As depicted herein, the base portion may rest flat on a surface. Alternatively, the base portion may be supported upon a series of legs resting on a surface or other suitable support means.
In an alternative embodiment, the exercise devise 10 comprises an upper platform 22 supported above a base portion 30 and a user support rod 18 operatively connected to the base portion 30. The user support rod is connected to the base portion at a position below the upper platform, thereby providing a greater range of motion as compared to existing exercise devices.
In one embodiment, and with continued reference to FIGS. 1A-2, the intermediate support region 32 is contiguous with the rearward-facing ends 22b, 30b of both the upper platform 22 and the base portion 30, thereby elevating the upper platform 22 above the base portion 30 and substantially parallel thereto. The intermediate support region may be static as depicted herein or, alternatively, capable of adjustment. For example, the intermediate support region may be adjustable to vary the height of the upper platform relative to the base portion. Further, the intermediate support region may also be at least partially pivotal to permit adjustment of the angle of the upper platform relative to the base or the extent to which the upper platform rests above the base, or both, thereby enabling a user to customize the exercise device to their particular needs.
The embodiments depicted in FIGS. 1A-1B also include an upwardly-depending range limiter 34 extending from the forward-facing end 30a of the base portion 30 and a substantially cylindrical housing 36 integrally formed between the base portion 30 and the range limiter 34. The range limiter 34 serves to limit the forward range of the user support rod 18, thereby preventing over-extension of, and subsequent injury to, the user.
As depicted in FIGS. 1A-1B, the user support rod 18 has opposing first 18a and second 18b ends and an intermediate extent 18c therebetween, the first end 18a extends upward from the cylindrical housing 36 and has first and second positions. In the first position, the intermediate extent 18c is positioned within the elongate slot 16. In the second position, the intermediate extent 18c is positioned against the range limiter 34. In one embodiment, the second end 18b of the user support rod 18 further comprises a cylindrical sleeve 18d oriented perpendicular to the user support rod 18. As depicted herein, the user support rod 18 may comprise a single rod. However, the use of multiple support rods is also envisioned to be within the scope of the present disclosure.
The user support rod may further comprise at least one handle or armrest for increasing a user's ability to grasp the support rod and/or for increasing comfort while exercising. Straps may also be provided for stabilizing a user's interaction with the device 10. Further, the length of the user support rod 18 may be adjustable to accommodate users of varying height and/or flexibility, or to provide a fine adjustment of the portions of the body to be strengthened.
With reference now to FIGS. 1, 7A, and 7B, and to enable the pivoting of the user support rod 18, one embodiment includes a cylindrical shaft 38 positioned within the substantially cylindrical housing 36. The shaft 38 is statically received by the cylindrical sleeve 18d proximate the second end 18b of the user support rod 18 and is capable of rotation about its longitudinal axis within the substantially cylindrical housing 36. The exercise device 10 may further comprise a torsion spring (not shown) or other resistance-altering means engaging at least one of the user support rod 18 and the cylindrical shaft 38 for increasing or decreasing the user support rod's 18 resistance to movement. Further, the resistance may be adjustable to accommodate the demands of a particular user. As depicted herein, and to enable a user to achieve optimal extension while exercising with the device, the user support rod 18 is pivotally connected to the device at a position below the plane upon which a user is supported. Such an orientation permits greater extension, and thus a greater total range of motion, as compared to existing devices.
In one embodiment, and as discussed above, the device 10 includes a leg support system 20 connected to the body portion 12 for engaging the user's legs. The support system 20 comprises a support beam 42 pivoting between first and second positions, the first position adapted to engage the user's legs (See FIG. 1A-2). Alternatively, the support system 20 may be static or selectively positionable. Further, the support beam may be substituted for a pair of ankle cuffs or other means for restraining and/or stabilizing a user's legs during operation of the exercise device 10.
As depicted herein, the support beam 42 is operably connected to the body portion 12 via a pair of pivotal arms 44 adapted for receiving the pins 26 extending laterally from the rearward-facing end 22b of the upper platform 22. In the first position the support beam 42 is above the upper platform 22, and in the second position the support beam 42 is below the upper platform 22. Other attachment means, however, are within the scope of the present disclosure.
