Squat exercise apparatus

摘要: An apparatus utilizing squat maneuvers is provided for exercising and/or rehabilitating muscles and joints in the lower back, hip legs. A single carriage assembly (14) comprising four elongated members (32, 34, 36, 38) pivotably connected form of a rectangle provide parallelogram-type arrangement which provides pantographic-type motion to vertically oriented back support (16) that supported cantilever fashion by disposed member (34) (14). The maintained its vertical orientation during while being moved along an arcuate path as pantographic are formed structures exhibiting high resistance twisting moments pivotal connections (58, 60, 62, 64) between these near pressed-fit tolerances so inhibit any looseness at could cause binding maneuvers.
