Abstract: Even when a damper is provided for absorbing impact and collision noise produced during winding a screen in an automatic winding screen device, the resistance during unwinding the screen is reduced as small as possible, and in the automatic winding screen device having a coil spring fixed to a bracket at one end of a winding box, the other end of the coil spring being fixed to a winding shaft, and the damper for alleviating the impact and collision noise, between the damper on a fixed shaft fixed to the winding box and the winding shaft, a one-way clutch mechanism is interposed in that when the winding shaft is rotated in a direction unwinding the screen against the rotational biassing force of the coil spring, the connection between the damper and the winding shaft is cancelled while when the winding shaft rotates in a direction winding the screen, the damper is connected to the winding shaft.

Abstract: An automatic wind-up screen device where resistance in screen-stretching operation is reduced as much as possible even with a damper provided in the device to absorb shock and collision noise during screen wind-up operation. One end of a coil spring is fixed to a bracket of a winding box, the other end is fixed to a winding shaft, and the damper is provided to absorb shock and collision noise. A one-way clutch mechanism is provided between the damper on a fixed shaft fixed to the winding box and the winding shaft. The clutch mechanism cuts off the connection between the damper and the winding shaft when the winding shaft is rotated in the direction to stretch the screen against rotational urging force of the coil spring, and the clutch mechanism connects the damper and the winding shaft when the winding shaft is rotated in the direction to wind up the screen.
