Exercise Device with Knee Rest
An exercise device is disclosed. The exercise device includes an ankle rest structure and a housing. Within the housing, a drive mechanism is provided that is connected to the ankle rest structure. The drive mechanism moves the ankle rest in a reciprocating motion along a generally horizontal plane. The exercise device also includes a knee rest structure spaced away from the ankle rest and connected to the housing. In one embodiment, the knee rest is movable in a horizontal and vertical direction with respect to the housing.
This application claims a right of priority to U.S. Provisional Patent Application Ser. No. 61/420,172, filed Dec. 6, 2010, the entirety of which is hereby incorporated by reference herein.
BACKGROUNDTherapeutic exercise devices utilizing reciprocating ankle rests are known. In use, a person will lie flat on his back and place his ankles on the ankle rest. In operation, the ankle rest reciprocates horizontally in a side-to-side motion which causes the legs to swing back and forth. During this time, a person's legs are suspended above the floor or surface on which the person is resting such that the back of the knee is not supported by the exercise device. Improvements are desired.
SUMMARYAn exercise device is disclosed. The exercise device includes an ankle rest and a knee rest, both of which are connected to a housing. Within the housing, a drive mechanism is provided that is connected to the ankle rest. The drive mechanism moves the ankle rest in a reciprocating motion along a generally horizontal plane. The knee rest is spaced away from the ankle rest and is movable in a horizontal and vertical direction with respect to the housing. In one embodiment, the position of the knee rest is adjustable relative to the longitudinal axis of the ankle rest. In one embodiment, the knee rest is adjustable in a vertical direction relative to the longitudinal axis of the ankle rest. In one embodiment, the knee rest is adjustable in a horizontal direction relative to the longitudinal axis of the ankle rest. In one embodiment, the knee rest is adjustable in both the horizontal and vertical directions. The knee rest may also have a contoured top surface and have a width that is equal to or greater than the width of the ankle rest.
Reference will now be made in detail to the exemplary aspects of the present disclosure that are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like structure.

In order to sufficiently restrain the slide member 40 such that the slide member 40 can only move in a linear direction, at least one slide bar 28 is provided that engages with a corresponding slot 46, or optionally a bore, within the slide member 40. As can be seen, slide bar 28 and slot 46 are parallel to longitudinal axis Y-Y. In one embodiment, a second slide bar 28 and slot or bore 46 are provided below the slot 42 to additionally secure the slide member 40.

In the embodiment shown, first frame member 24, second frame member 26, cam arm 30, and slide member 40 are made of ABS plastic. Base plate 80 is shown as being made of a metal, such as steel. The support feet 82 on base plate 80, shown in

In the exemplary embodiment shown, the upper member 102 is connected to a base member 106 by a pair of support legs 110. Base member 106 is for supporting upper member and for providing a connection point between the knee rest 100 and the frame 80 of the housing 10. As shown, base member 106 has a pair of rubber support feet 108 for contacting the surface on which exercise device 1 rests. Support feet 108 also provide for vibration isolation. Base member 106 further includes a pair of collars 112 for receiving support legs 110. Support legs 110 are slidable within the collars 112 such that the upper member 102 of the knee rest 100 can be adjusted in a vertical direction V. By use of the term “vertical direction” is meant a direction that is generally perpendicular to the surface on which the exercise device 1 rests which is also the plane of the base plate 80. This adjustment allows an individual user to set the knee rest 100 height at a satisfactory level. In one position, the height of the upper member 102 is set to be lower than the height of the ankle rest 70 (i.e. axis X-X is lower in the horizontal plane than axis Y-Y). In the embodiment shown, upper member 102, base member 106, and support legs 110 are constructed from ABS plastic, although other materials and shapes may be used.
As shown, each collar 112 includes a locking mechanism 114 that operates to bind each leg 108 to the collar 112. This feature ensures that once the vertical height of the knee rest 100 is set, that it is securely retained in this position. In one embodiment, the legs 110 have a plurality of notches 110a for receiving a detent 114a on the locking mechanism 112. In one embodiment the locking mechanism 114 is a latch. However, those skilled in the art will appreciate that other means for locking the legs 110 may be used, such as pins. Referring to
In the exemplary embodiment shown, the base member 106 of the knee rest 100 is connected to the base plate 80 of the housing 10 by a pair of extension legs 90. Extension legs are for horizontally spacing the knee rest 100 from the ankle rest 70 a desired distance such that the exercise device 1 can be adjusted to accommodate the particular leg length and proportions of a particular user.
As shown, each extension leg 90 includes an inner member 92 that is slideable within an outer member 94. The inner member 92 is received into recess 116 and secured by screws (not shown) while the outer member is shown as being secured to the base plate 80 via clamps 99. One skilled in the art will appreciate that inner and outer members 92, 94 may be respectively attached to the base member 106 and base plate 80 by a variety of means known in the art. In the embodiment shown, members 92, 94 are aluminum tubes. However, one skilled in the art will appreciate that other materials and shapes may be used.
Each extension leg 90 is also provided with a collar 96 having a locking mechanism 98. In the embodiment shown, collar 96 and locking mechanism 98 are secured to outer member 94 and configured such that locking mechanism can selectively engage the inner member 92. In one embodiment, locking mechanism 98 is a latch. However, those skilled in the art will appreciate that other means for locking the legs 110 may be used, such as pins. In the embodiment shown, collar 96 and locking mechanism 98 are primarily constructed from ABS plastic, although other materials may be used. Referring to
By operation of the locking mechanism 98, the relative position of the inner member 92 to the outer member 94 may be set to a fixed position. Because the inner member 92 is slideable with respect to the outer member 94, the knee rest 100 position may be adjusted in a horizontal direction H such that the desired spacing between the knee rest 100 and the ankle rest is achieved (i.e. axis X-X is spaced a desired horizontal distance from axis Y-Y). By use of the term “horizontal direction” is meant a direction that is generally parallel to the surface on which the exercise device 1 rests and perpendicular to the longitudinal axis X-X of the leg rest 100.
