Abstract:
1. A synchronous movement device applied to dual-shaft system, comprising: a first shaft having a fixed end and a pivoted end; a driver and a driving rail disposed at the pivoted end of the first shaft; a subsidiary driver disposed at the pivoted end of the first shaft, the subsidiary driver being rotatable with the first shaft; a second shaft having a fixed end and a pivoted end; a reactor and a reacting rail disposed at the pivoted end of the second shaft; a subsidiary reactor disposed at the pivoted end of the second shaft, the subsidiary reactor being synchronously rotatable with the second shaft; each of the driver, the subsidiary driver, the reactor and the subsidiary reactor including an outer surface peripherally terminating at a first slope and a second slope, the first slope of the driver being in contact with the first slope of the subsidiary driver, the driving rail being defined between the second slope of the driver and the second slope of the subsidiary driver, the first slope of the reactor being in contact with the first slope of the subsidiary reactor, the reacting rail being defined between the second slope of the reactor and the second slope of the subsidiary reactor; and a link unit having a driving boss and a reacting boss respectively positioned in the driving rail and the reacting rail, the link unit having first and second faces slidably engaging at least one of the driver and subsidiary driver outer surfaces and at least one of the reactor and subsidiary reactor outer surfaces, respectively, the driver being rotatable with the first shaft to push the link unit to move along the first and second shafts so as to make the reactor rotate in a direction reverse to a moving direction of the driver, whereby the first and second shafts are synchronously rotated.
