Securing and arming device and use thereof

Abstract

A securing and arming device has an operating body. Prior to an arming time, this operating body is secured in a position of rest on a support device, namely by means of a securing element, which here is in a securing position. If the securing element is moved into a release position, it releases the operating body to make a movement in relation to the support device. After the arming time, the trigger body is in an operating position by means of a rotating movement in relation to the support device. A delay element is designed to be driven in the course of the rotating movement of the trigger body and to delay the rotating movement of the trigger body. The trigger body and the delay element are arranged inside each other so that they constitute an outer wheel shaft-free wheel and an inner wheel shaft-free wheel. The two wheels have parallel geometric wheel axes and define a ring-like gap. At least one of the wheels has a wavy circumferential surface facing the other one of the wheels with wave crests and wave troughs. The wheels rest with areas of their surfaces facing each other on motion transfer bodies, which are located in the ring-like gap and are seated therein in a radially displaceable manner.
