发明名称 Training device for football players
摘要 A device for training football players is disclosed. The device trains the user in the art of blocking. The apparatus includes a frame which defines an upwardly-sloping track, and a carriage which moves along the track. The carriage is connected, by a pulley system, to a hydraulic or pneumatic cylinder, or equivalent device, for imparting resistance to the movement of the carriage along the track. Forcing the carriage upwardly along the track also pushes a piston into the cylinder, retarding the movement of the carriage. A second pulley is also provided for retracting the piston from the cylinder when the carriage is moved back to its original position. The device trains the player to shift his weight while blocking, so as to tend to lift the opposing player from the ground. The amount of resistance to the movement of the carriage can be varied to simulate opposing players of varying weights.
