DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slide rail locking device for maintaining a state in which shelves such as display shelves are stored in a main body.

[0002]

2. Description of the Related Art Conventionally, as a slide rail for maintaining a drawer or a shelf of a display shelf in a state of being stored in a main body, a stopper is formed by bending an end of a fixed side rail inward, and is formed of an elastic body. By attaching a rebound prevention member having a chevron-shaped engaging projection and engaging the engaging projection with a stopper formed by bending the end of the moving-side rail inward, the moving-side rail becomes a fixed-side rail. Maintains the most retracted state (for example, Japanese Utility Model Application Laid-Open No. 57-189450), or prevents part of the rear end of the board of the fixed rail from projecting toward the movable rail by elasticity to prevent rebound. There has been provided a structure in which a protruding piece is formed and a stopper portion is formed on the inner surface of the rear end of the moving side rail so that the rear end of the rebound preventing protruding piece elastically abuts (Japanese Utility Model Application Laid-Open No. 60-187633). .

However, in each of these cases, the moving rail is elastically locked to the fixed rail while the moving rail is housed in the fixed rail.
If the main body tilts or swings during transportation or due to an earthquake or the like, there is a possibility that the shelf board or the like may unexpectedly pop out. For this reason, the stopper at the time of storage is made to protrude upward at the rear end of the fixed-side rail, and is locked to the rear end of the storage-time stopper when the movable-side rail is most stored at the rear end of the movable-side rail. A stopper member is provided rotatably, a rotation operation shaft is connected to the stopper member, the tip of the rotation operation shaft is extended to the front end of the moving side rail, and the rotation operation shaft is Means for releasing the locked state of the stopper and the stopper member at the time of storage by rotating them has also been provided (Japanese Utility Model Publication No. 62-8761), but the number of parts is large, and the slide rail itself is welded to the slide rail itself. Processing is required, which is a factor of cost increase.

It is blocked by the mounting board 61 and the board 22.

The movable side rail lock member 6 is attached as described above, and the movable side rail 2 is completely housed in the fixed side rail 1, and the engaging hole 68 of the guide inclined piece 65 is fixed to the fixed side rail front end stopper. 13 (the state shown in FIG. 2), and the moving-side rail 2 does not inadvertently move forward unless the engaged state is released by the user's intention. next,
When pulling out the movable side rail 2, the operation protruding piece 66 protruding forward of the fixed side rail 1 (movable side rail 2) is pushed with a fingertip toward the board 22 side (in the direction of the arrow in FIG. 4) of the movable side rail 2. The engagement hole 68 and the fixed rail front end stopper 13
Is disengaged, and the movable rail 2 is pulled forward while maintaining this state.

When the movable rail 2 is moved backward from the pulled-out state (when the movable rail 2 is stored in the fixed rail 1), the movable rail lock member 6 is moved.
Guide inclined piece 65 contacts the end surface of the fixed-side rail front end stopper 13, so that the guide inclined piece 65 moves rearward while moving toward the mounting board 61 side. Then, when the engagement hole 68 reaches a position corresponding to the fixed-side rail front end stopper 13, that is, the slide rail 100 is in the maximum contracted state (the state in which the intermediate rail 4 and the moving-side rail 2 are stored in the fixed-side rail 1). ), The guide inclined piece 65 returns to the initial state due to the elasticity, the engagement hole 68 and the fixed-side rail front end stopper 13 are engaged, and the slide rail 10 is in the maximum contracted state (intermediate to the fixed-side rail 1). The rail 4 and the moving side rail 2 are stored) to prevent the moving side rail 2 from accidentally jumping forward.

Next, a second embodiment of the moving side rail lock member will be described with reference to FIGS. The moving-side rail lock member 7 of the second embodiment is integrally formed of a leaf spring material as in the first embodiment. That is, the mounting board 71 located on the inner surface of the distal end portion of the board 22 of the moving rail 2, and the pressure contact which is connected to the upper and lower ends of the mounting board 71 and fits and presses the bent edges 21, 21 of the moving rail 2. Wing piece 72, 72
A fitting portion 70 provided continuously with a front end portion of the mounting board 71 and fitted to the movable rail front end stopper 221;

The locking rail 88 is locked to the inner surface of the fixed rail front end stopper 13 (the state shown in FIG. 8), and the movable rail 2 is inadvertently moved forward unless the engaged state is released by the user's intention. Never move to

Next, when pulling out the movable rail 2, the operation protruding piece 86 protruding forward of the fixed rail 1 (movable rail 2) is touched by a fingertip to the board 22 side of the movable rail 2 (arrow in FIG. 8). To release the locked state of the locking step portion 88 and the fixed-side rail front end stopper 13, and pulls out the movable side rail 2 forward while maintaining this state.

When the movable rail 2 that has been pulled out is moved rearward (when the movable rail 2 is housed in the fixed rail 1), the guide inclined piece 85 of the movable rail lock member 8 is moved to the fixed side. Since it comes into contact with the end face of the rail front end stopper 13, the guide inclined piece 85 moves rearward while moving toward the mounting board 81. When the front end of the locking step portion 88 is located on the inner surface side of the fixed-side rail front end stopper 13, that is, the slide rail 100 is in the maximum contracted state (the intermediate rail 4 and the moving-side rail 2 are stored in the fixed-side rail 1). When the sliding rail 1 comes into contact, the guide inclined piece 85 returns to the initial state due to the elasticity, and the locking step 88 is locked on the inner surface of the fixed-side rail front end stopper 13, and the slide rail 1
The maximum reduced state of 0 (the state in which the intermediate rail 4 and the movable rail 2 are accommodated in the fixed rail 1) is maintained, and the movable rail 2 is prevented from inadvertently jumping forward.
