Abstract

A knee exercising device is described. It provides for the manual control of pressure to the lower leg in selectively flexing either the right or left leg knee joint. The device includes a plate member interposed between the users buttocks and a chair sear on which the user is sitting. The leg of the knee being exercised is held in an elevated position by a pad between the thigh of that leg and the chair seat. A lever is pivotally mounted, intermediate its length, on the plate member. The lever swings in a vertical plane between the users legs about an axis generally vertically aligned with and parallel to the axis of the knee joint being exercised. A leg engaging pad is removably mounted on the lower end portion of the lever. The removable mounting enables the pad to be selectively positioned to engage the front, shin portion or rear calf portion or either leg, at an area adjacent to and spaced above the user's foot.

Dependent claims

A knee exercising device for use by a user sitting on a chair, or the like, with the leg of the knee to be exercised being raised by a spacer placed between the thigh of that knee and the seat of the chair, said device comprising

a relatively thin, plate member adapted to be interposed between the buttocks of the user and the chair seat and position the device relative to the user's knees, said plate member being removably positioned on the chair seat,
a lever disposed between the legs of the user and pivotally mounted, intermediate its length, on said plate member for movement about a horizontal pivot axis, the pivotal axis of the lever being positioned generally parallel to and in general vertical alignment beneath the pivot axis of the knee joint, the upper portion of said lever being engagable by the user,
a leg engaging pad, and
means for mounting said pad on the lower portion of said lever for engagement with the lower leg, of the knee being exercised, in an area adjacent to and spaced above the user's foot,
whereby the user may manually displace the upper end of the lever to apply a controlled pressure on the lower leg in flexing the knee joint.
