PROBLEM TO BE SOLVED: To provide a method of re-connecting an engagement coupling after each furniture component has fallen in an emergency.SOLUTION: A blocking slider 18 is guided so as to move in an axial direction and connected to a change-over element directly or indirectly. A load is applied to a direction of the connection position of the change-over element by a spring. The blocking slider can move against the load of the spring in a direction of a release position of an engagement coupling 14 by another operation mechanism 21. A locking claw 24 is movably fixed to a case and can be caught in a back of a latching nose 23 of the blocking slider 18 when the blocking slider 18 reaches a position corresponding to the release position of the engagement coupling 14. A movable sliding part 25 is provided in the case, and the locking claw 24 is released from the latching nose 23 by the sliding part 25 when a corresponding furniture component is in a state of falling. |
