Abstract

The retracting device tends to wind up the strip when it is extended, and a leaf spring interacts with several pins on a ratchet wheel and locks the strip when it is extended. One spring end is permanently joined to the drum the spring is under the strip, so that it is pressed to the drum by the strip. It is released at the end of strip unwinding in order to control the ratchet wheel rotation a fixed stop is provided, engaged by the spring after the ratchet wheel has been rotated over a certain angle when the spring moves back from the stop, driven by the retracting device, it engages every second time on one or the other pin.
