Abstract (en)

[origin: EP1278039A2] The securing and arming device has an operating body and a delay element one inside the other, so that they constitute outer and inner wheels without a wheel shaft. The wheels have parallel geometric wheel axes and define a ring-like gap between them. At least one of the wheels is embodied to be wavy on its surface facing the other wheel, with wave crest and troughs over its circumference. <??>The securing and arming device comprises an operating body (20) which, prior to an arming time, is secured in its position of rest on a support device (12) by a securing element (30) which is in a securing position; can, for the purpose of arming, be released by the securing element which is moved into its release position in relation to the support device; and can, after the arming time, be brought into an operating position by a rotary movement around a trigger axis. The device has a delay element (22) which can be driven in the course of the rotational movement of the operating body and to delay the rotational movement of the operating body. The operating body and the delay element are arranged one inside the other, so that they constitute outer and inner wheels without a wheel shaft. The wheels have parallel geometric wheel axes and define a ring-like gap between them. At least one of the wheels has a wavy surface facing the other wheel, with wave crest and troughs over its circumference. With areas of the wheel surfaces facing each other, the wheels rest against motion transfer bodies (24) in the ring-like gap and which are seated radially displaceable in the solid gap. <??>An Independent claim is also included for a spin-stabilized projectile comprising a casing defining a rotating part of the projectile and the longitudinal axis of the projectile about which the projectile is spin-stabilized; and a securing and arming device.
