Muscle training framework - has electrically controlled travelling weight on lever arm for increasing or decreasing effort required to lift lever

摘要

The training apparatus consists of a portable or fixed framework (2) having a lever (4) connected by a hinge (3) to the rear of the frame (2) and a shock absorber (7) offering little resistance to any upward movement but preventing a sudden fall of the lever (4). An electric motor (8) and a bearing block (9) are also fixed on the lever (4) and a screwed shaft (10) along which a threaded heavy weight (11) moves, is rotated by operating a control knob (13) positioned on a cross tube (5), used as a grip by the person training and connected to the motor (8) by cables (12). Thus the position of the weight (11) can be Varied by rotating the screw thread (10) in either direction, and the effort required to lift the lever (4) increased or decreased according to the user's requirements. An electronic or mechanically controlled monitoring indicator (28) can be mounted in the framework (2) to give the user a reference to the force required.
