Abstract:
A rotating-lock closure with a traction unit, comprising:a closure housing that has a socket key opening on one outside end and a rotating lock on tie other, inside end; which can he inserted by one end through a passageway in a wall or a door leaf, matched to the outside cross-section of the housing and which can be fixed in position; a first bearing area which is open towards the outside end and coaxial with the housing axis and which is intended for a socket key receiving head as well as a second bearing area open toward the opposite inside end of the housing that is adjacent to the first bearing area and which is intended for a rotating-lock driving support that supports said rotating-lock and is mounted so as to be capable of axial and sliding displacement and of rotation in the second bearing area; a coupling device being provided between the socket key receiving head and the rotating-lock, which device is provided with a cam pin/cam track device for the rotation and/or axial displacement of the rotating-lock relative to the housing upon rotation of the socket key receiving head, and which permits a limited angular freewheeling between the socket key receiving head and the rotating-lock; a shaft having a rounded cross section and extending from the socket key receiving head protruding beyond the rotating-lock driving support and also having a transverse opening at its protruding end for receiving a cam pin; a cam track, on which the cam pin is guided against the force of a spring, being formed by the side of the lock facing away from the housing; and the outer periphery of the lock driving support having a non-rounded cross section and being capable, in It passageway also having a non-rounded cross section, of axial and sliding displacement in a first portion of the second bearing area and of limited rotation in a second portion of the second bearing area; wherein the rotating-lock closure comprises a lock receiving part which can be fixed to the housing or frame and which forms the surface behind which the rotating-lock engages; wherein the rotating-lock is toggle-shaped; wherein the lock receiving part has the shape of a cup, the open end of which can be screwed to the seating, the bottom of the cup forming an essentially rectangular opening which permits with some lateral play the passage of a toggle-like rotating-lock when this is in a position aligned with the longitudinal extent of the opening.
