When the force in the closing direction with respect to the housing 106 is removed, the restoring force of the elastic member 130 acts on the sliding opening / closing unit 120, and the restoring force of the extension part 114a acts on the locking part 114. The locking protrusion 114 is locked to the inner groove 122b side for the second period to fix the transfer rail 104 (see arrow ⓐ direction and ⓑ direction).

Next, when the housing 106 is to be opened again, the pressing operation in the closing direction is performed again with respect to the housing 106 in the closed state.

As a result, the extension portion 114a is elastically deformed while the locking protrusion 114, which is engaged on the second groove inner groove 122b side of the locking body 122, is guided to the locking guide piece 124. The lock is released from the guide groove 122b and moves toward the inner groove 122c for the third time period, thereby releasing the lock with the locking body 122.

Next, as the elastic member 130 elastically reacts by the restoring force, the conveyance rail 104 moves in the opening direction to open the housing 106 (see arrow ⓒ direction).

In this process, a reverse action may occur in which the locking protrusion 114 moves backward from the third groove inner groove 122c to the second groove inner groove 122b, and the reverse operation prevents the reverse operation protrusion 123. By the elastic deformation of the interfering block portion 114 to move from the third inner groove 122c to the second inner groove 122b side can be blocked.

As such, the sliding opening and closing unit 120 having the locking body 122 with which the locking protrusion 114 is released has a catch locking protrusion of the elastic catch unit 125 in the catch locking protrusion receiving groove 104a-1. 125b) is accommodated and the front end portion of the fixing part 104a is accommodated in the fixing part receiving groove 125d, thereby stably moving in the opening direction, thereby opening the housing 106.

Thereafter, when the catch catching protrusion 125b reaches the catch catching protrusion accommodating hole 116b-1 by the movement of the sliding opening / closing unit 120, the catch catching protrusion 125b is pivoted downward by elastic restoring and catching. As the accommodation is released from the locking protrusion accommodating groove 104a-1, the transfer rail 104 may be further opened.

The sliding device 100 according to the present invention for locking or releasing the housing by the above-described process allows the sliding opening / closing unit 120 to be moved in the closing or opening direction by the elastic catch unit 125. The locking member 122 may be locked and released through the locking protrusion 114, and the reverse movement of the locking protrusion 114 may be blocked by the reverse operation preventing protrusion 123 to simplify the configuration of the product while preventing malfunction. There is an advantage that can be prevented.

Although the exemplary embodiments of the present invention have been described above by way of example, the scope of the present invention is not limited to such specific embodiments, and the scope obvious to those skilled in the art to which the present invention belongs belongs to the scope of the claims of the present invention. It should be interpreted as belonging to.
