Branching device for guide track

Abstract

Abstract PURPOSE:To reduce power, by providing a crankshaft with a counterweight and connecting the crankshaft as a seasaw and making the torque around the crankshaft almost zero. CONSTITUTION:When a driving crank arm 28 swings a slitted arm 27 from a first crankshaft 11 through a trosional flexible joint 24 to a swing angle theta1 larger than another swing angle theta, the torsional flexible joint 24 undergoes twisting torque and torsional deflection. Since the swing angle beta of the driving crank arm 28 has already exceeded a dead point D, the swing angle of the slitted arm 27 has become theta2 lower than theta1 but is still larger than theta. Therefore, a force P is applied to a roller 29 by the twisting torque of the torsional flexible joint 24 to prevent the driving crank arm 28 from returning against operator's will. As a result, the first crankshaft 11 is locked up between the reaction R of a stop 33 and the force P. Therefore, the power required is reduced and the device is simplified.
