Locking device on two bodies movable in a sliding manner relative to each other on a guide track

A locking device on two bodies slidingly movable relative to each other on a sliding track of a guiding body, the two bodies comprising a sliding body and the guiding body,

• wherein the sliding body is movable in a sliding direction on the sliding track of the guiding body, and wherein the sliding body is lockable and form-fittingly connectable to the guiding body by the locking device in an end position,
• wherein the locking device has a locking pin, which, in the sliding body, movable transversely to the sliding track via a straight guide, is form-fittingly guided transversely to a movement direction of the locking pin, between a neutral position, in which the locking pin retracts into a contour of the sliding body while being in a region of the sliding track, and a locking position, in which the locking pin cooperates with an engagement of the guiding body and form-fittingly locks a relative sliding movement of the sliding body in the sliding direction,
• wherein a socket spanner in the sliding body is straightly guided in a sliding manner parallel to the sliding direction, with a relative movement in a closing direction and an unlocking direction,
• wherein the locking pin with an operating end protrudes in a pocket of the socket spanner,
• wherein the pocket cooperates with the locking pin:
• with an unlock-action pairing out of two edges and/or surfaces slidingly movable relatively to each other in a plane stretched by the movement direction of the locking pin and the sliding direction of the sliding body, and wherein the unlock-action pairing have a first operation direction for a straight guidance of the locking pin,
• as well as with a push-action pairing with a pushing-edge, which is formed on the pocket transversely to the sliding direction of the sliding body and transversely to the closing direction, and which engages the straightly guided region of the locking pin in the closing direction,
• wherein by the movement of the socket spanner, in an unlocking direction, initially the locking pin is drivable into its neutral position and then the sliding body is movable in the sliding direction by a form-fitting engagement of the pushing edge simultaneously with the socket spanner, but independently of the guiding body;
• with a drive-out-action pairing out of two edges and/or surfaces slidingly movable relatively on each other in a plane stretched by the movement direction of the locking pin and the sliding direction of the sliding body, and the drive out action pairing have a second operating direction for the straight guide of the locking pin, wherein one driving out surface of the drive out action pairing is inclined for the straight guide of the locking pin and wherein the one driving out surface on the side facing away from the pushing edge and the unlock-action pairing—in the closing direction—is formed, on the one hand, at the pocket and on the other hand, on the locking pin;
• as well as with a lock-action pairing with a locking surface formed subsequently to the drive-out-action pairing on the pocket, transversely to the straight-guide of the locking pin, and which engages the operating end of the locking pin in its locking position,
• wherein by the movement of the socket spanner initially the locking pin in closing direction can be driven into its locking position and therein by the locking surface can be form-fittingly fixed.
