发明名称 Leg extension machine with upwardly curved tracks
摘要 An exercise device that allows the user to extend each leg separately from a sitting position. A pair of upwardly curved tracks (20) are affixed to horizontal base members (10) by the rear support members (16) and to vertical base members (12) by the top support members (18). Tracks (20) extend upwardly toward the forward end of the invention. The two foot plates (31) are affixed to tracks (20) by the foot plate attachments (30) to move forward and rearward. A pair of foot supports (32) are affixed to foot plates (31), wherein they can adjustably fit to a human being's feet as the legs are extended. Embodiments include different options for supplying resistance to the movement of the foot supports, including the use of hydraulic cylinders (42) or straps (36). Other embodiments include a means for carrying the device and for collapsing it for easy storage. It can easily be used in many environments including at a desk or on a sofa.
