Abstract
A locking apparatus which includes a locking element, an unlocking element, and a latching member. In the rest position, two arms of the latching member are maintained in their latched positions by compressed springs. To unlock, the unlocking element is turned in one or the other direction of rotation, whereby one of two inclined surfaces lifts one arm against the restoring force of a spring via a bearing surface of the unlocking element. Upon further turning of the unlocking element, an entraining projection from this element pulls the locking element along with it in the same direction of rotation. If the unlocking element is turned in the opposite direction, the arms automatically return to a rest position.
