Abstract

Apparatus for locating and securing an object in first and second end positions between which it is movable comprising two parallel pivot arms which support the object for movement between its end positions and fittings at the end positions on both sides of the object. The fittings are provided with inclined guide surfaces and latching holes adapted for receiving latching pins on the object under spring pressure when the object is at the end positions. Located around the latching pins are guide nuts adapted for cooperating with the inclined guide surfaces in order to position the object as it approaches and occupies its end positions. The inclined guide surfaces of the fittings face one another and converge in the direction of entry of the object between the fittings. The fittings also have guide surfaces extending perpendicular to the inclined guide surfaces whereby the guide nuts are guided along their end faces and along circumferential guide surfaces. The circumferential guide surfaces of the guide nuts are urged against the associated guide surfaces of the fittings by a gas cartridge pivotally connected to the pivot arms and the object.
