Abstract:
1. A spring-biased locking bolt comprising: an operating button having a sleeve section integrally formed with the operating button and oriented in an axial direction, said sleeve section having a first interior polygonal profile continuous through the sleeve section in the axial direction and a second interior polygonal profile formed in an end face of the sleeve section and extending a predetermined axial distance from the end face, with the second interior polygonal profile having an angular offset in the peripheral direction with respect to the first polygonal profile; a bolt connected with the operating button; a sleeve adapted to be screwed into a corresponding opening in a part, said sleeve having a circular exterior surface extending axially over a portion of the sleeve facing the operating button and an exterior polygonal shoulder extending axially over a remaining portion of the sleeve, wherein the bolt is movable in the sleeve under a spring bias and engagable in the opening; wherein in a lowered position of the operating button, the polygonal shoulder of the sleeve engages with the first polygonal profile disposed in the sleeve section, and wherein in a pulled-out position of the operating button, the polygonal shoulder of the sleeve engages with the second offset polygonal profile under the spring bias by rotating the operating button by the angular offset, thereby forming a catch.
