When pushed back further, the inclined portion 33 is pushed by the engaging portion of the engaging member 22, and the locking member 28 rotates in the direction opposite to the arrow B as shown by a two-dot chain line in FIG. The engaging portion of the locking member 28 gets over the locking claw 32 of the locking member 28. Since the locking member 28 is not pushed by the engaging member 22, the locking member 28 is rotated in the direction of arrow B by the biasing force of the spring 39, and the engaging portion of the engaging member 22 and the locking claw 32 of the locking member 28 are again connected. The slide shelf 13 is arranged in the exhibition room 4 by engaging.
[0020]
Since it is configured as described above, even if the product is about to fall down due to any moment when the slide shelf 13 is advanced or retracted, the other available hand can be attached. Can be prevented from falling or dropping. When the slide shelf 13 is advanced or retracted, the fixing hole 27 formed in the support bracket 25 fixed to the fixed rail 24a of the slide rail 24 is larger than the screw diameter of the fixing screw 26. Since the slide shelf 13 is attached to the slide support portion 12 by adjusting the position of the diameter difference, the slide shelf 13 can be moved straight forward and backward smoothly in the front-rear direction. Further, since the steadying member 29 is rotated and brought into contact with the inner surfaces of the left and right side walls 3, the shelf bracket 23 is restricted from swinging in the left-right direction, and the sliding shelf 13 can be smoothly advanced and retracted. There is no risk of damaging the glass plate of the side wall 3.
[0021]
In the above-described embodiment, the locking portion 21 is configured using the locking member 28 having the claw tip of the locking claw 32 facing upward. However, the present invention is not limited to this. For example, as shown in FIG. It may be configured. That is, the locking portion 51 includes a locking member 53 with the claw tip of the locking claw 52 facing downward and an engaging member 54 that engages with the locking member 53, and the locking member 53 is connected to the front end portion of the shelf bracket 23. The spring 55 is urged in the direction of arrow D in FIG. The inclined portion 56 formed at the front edge of the locking member 53 is inclined downward toward the rear. Further, the engaging member 54 is configured to be fixed to a price card rail 58 that is rotatably provided so as to be biased in the direction of arrow E in FIG.
[0022]
With this configuration, when the slide shelf 13 is arranged in the exhibition room, the engaging member 54 fixed to the price card rail 58 of the locking portion 51 defines the lower end engaging portion of the shelf bracket 23. It is engaged with the locking claw 52 of the locking member 53 attached to the front end, so that the slide shelf 13 does not advance forward. When pulling the slide shelf 13 forward from the exhibition room, the price card rail 58 is rotated in the direction opposite to the arrow E against the urging force of the spring hinge 57 with one hand. As a result, the engagement between the engagement portion of the engagement member 54 and the engagement claw 52 of the engagement member 53 is released, and in this state, that is, the price card rail 58 is rotated with one hand, the slide shelf Pull 13 out. By this pulling, the engaging part of the engaging member 54 acts on the tip of the pawl 52 and rotates the latching member 53 in the direction opposite to the arrow D, so that the slide shelf 13 can be easily moved with only one hand. It can be pulled out greatly in the forward direction.
[0023]
On the other hand, when the slide shelf 13 pulled out in the forward direction is pushed back, the engaging portion at the lower end of the engaging member 54 first comes into contact with the inclined portion 56 of the locking member 53. When pushed back further, the inclined portion 56 is pushed by the engaging portion of the engaging member 54 and the locking member 53 rotates in the direction opposite to the arrow D, and the engaging portion of the engaging member 54 is engaged with the locking member 53. Get over the pawl 52. Then, since the locking member 53 is not pushed by the engaging member 54, the locking member 53 is rotated in the direction of arrow D by the biasing force of the spring 55, and the engaging portion of the engaging member 54 and the locking claw 52 of the locking member 53 are again connected. The slide shelf 13 is engaged and arranged in the exhibition room.
