Abstract

Disclosed is a rail locking device in a rail structure having a mounting area provided in a first rail or a second rail. The first and second rails are coupled to each other and the first rail may slide along the second rail. In particular, the rail locking device includes a moving cover portion mounted in the mounting area, and a locking portion having wound therein the moving cover portion extending from the mounting area and configured to selectively limit extraction of the moving cover portion to temporarily fix the first rail that slides forwards or rearwards of the second rail in place.

First claim

What is claimed is:

1. A rail locking device in a rail structure having a mounting area provided in one of two rails, a first rail and a second rail being coupled to each other and the first rail being configured to slide along the second rail, the rail locking device comprising:
a moving cover portion mounted in the mounting area and configured to extend from the mounting area; and
a locking portion configured to selectively limit extraction of the moving cover portion to temporarily fix the first rail that slides forwards or rearwards of the second rail in place,
wherein the locking portion is further configured to:
selectively limit the extraction of the moving cover portion at a rear of the second rail based on an occurrence of a forward impact, and
selectively limit the extraction of the moving cover portion at a front of the second rail based on an occurrence of a rearward impact.

2. The rail locking device of claim 1 , wherein the moving cover portion comprises:
a mounting member mounted to the mounting area, the mounting area provided in a pair and disposed at a front and a rear of the first rail, respectively; and
a draw-out member extending from the mounting area and being wound inside the locking portion.

3. The rail locking device of claim 1 , wherein the locking portion comprises:
a main body in which the moving cover portion is wound;
a first latch mounted inside the main body and configured to rotate as the moving cover portion is drawn out, the first latch including an outer circumferential surface provided with gear teeth;
a second latch, having a locking piece protruding from the second latch, the locking piece being configured to be selectively tooth-coupled with the gear teeth, and rotatable about a rotation axis; and
a torsion spring, mounted inside the main body and configured to elastically support the second latch so that the second latch maintains an initial position of the second latch.

4. The rail locking device of claim 3 , wherein the initial position is set as a position where the locking piece is released from the gear teeth.

5. The rail locking device of claim 3 , wherein the second latch comprises:
a lifting guide configured to be selectively lifted by the moving cover portion; and
a coupling guide, coupled to the torsion spring and configured to rotate about the rotation axis as the lifting guide is lifted so as to guide the locking piece to be tooth-coupled to the gear teeth.

6. The rail locking device of claim 5 , wherein the second latch is configured to maintain the initial position when an elastic restoring force acting on the coupling guide by the torsion spring is greater than a force with which the moving cover portion is drawn out.

7. The rail locking device of claim 5 , wherein, when a momentary force with which the moving cover portion is drawn out is greater than an elastic restoring force acting on the coupling guide by the torsion spring, the second latch is configured to rotate so that the locking piece is engaged with the gear teeth.

8. The rail locking device of claim 5 , wherein the main body comprises a draw-out guide configured to guide lifting of the lifting guide and draw out the moving cover portion.

9. The rail locking device of claim 1 , wherein the locking portion is provided in pairs, each of the pairs being mounted at the front and the rear of the second rail, respectively.
