[0041] Next, a method of attaching the shelf board fixing device 5F on the front end portion side to the shelf board support piece 22 on the front end portion side will be described with reference to FIG. 5(b).

[0042] Fit the convex portion 5a into the oval hole 22a and fit the boss portion 5b into the screw hole 22b. Then, insert the pointed screw 4 from the lower side of the shelf board support piece 22 on the front end portion side and screw it into the female screw of the boss portion 5b. By sandwiching the shelf board support piece 22 between the shelf board fixture 5 and the washer 40, the shelf board fixture 5 on the front end portion side is fixed to the shelf board support piece 22, and the shelf board fixing device 5F on the front end portion side is fixed to the shelf board support piece 22 on the front end portion side.

[0043] As shown in FIG. 1, the shelf board fixing device 3F is fixed to the shelf board support piece 21 of the bracket 2, and the shelf board fixing device 5F on the front end portion side is fixed to the shelf board support piece 22 on the front end portion side, respectively. As shown in FIG. 2, for the shelf board fixing device 3F fixed to the shelf board support piece 21 of the bracket 2, the tip 4b of the pointed screw 4 protrudes toward the shelf board side from the horizontal portion 30. In the present embodiment, it protrudes 1 mm above the horizontal portion 30. Similarly, although not shown, for the shelf board fixing device 5F fixed to the shelf board support piece 22 on the front end portion side, the tip 4b of the pointed screw 4 protrudes toward the shelf board side from above the upper portion of the shelf board fixture 5 on the front end portion side. In the present embodiment, it protrudes 1 mm above the upper portion of the shelf board fixture 5 on the front end portion side.

[0044] Next, a method of installing the shelf board 8 on the support member 1 attached to the wall surface will be described with reference to FIGS. 6 to 9.

[0045] As shown in Fig. 1, prepare the left and right brackets 2, 2 to which the shelf board fixing device 3F and the shelf board fixing device 5F on the tip side are respectively fixed. As shown in Fig. 6, insert the locking hook 24 into the slit 11 of the support member 1, and lower the bracket 2 to lock the brackets 2, 2 to the support member 1.

[0046] As shown in Fig. 6, gently push the wooden shelf board 8 into the bracket 31 of the shelf board fixing tool 3 from the front to the back (in the direction of the arrow in the figure) on both the left and right sides at the same time.

[0047] Subsequently, as shown in Figs. 7 and 8, while gently pushing the shelf board 8 toward the wall surface side, gently push the front side of the shelf board 8 against the tip 4 screwed into the shelf board fixing tool 5. By pushing in the shelf board 8, the tip 4b of the shelf board fixing device 3F on the rear end side and the tip 4b of the shelf board fixing device 5F on the tip side bite into the bottom surface of the shelf board 8 respectively. As shown in Fig. 9, the shelf board 8 is fixed on the bracket 2, and the display shelf device as the shelf device of the present invention is configured.

[0048] On the wall surface side of the shelf board 8, the upper surface of the shelf board 8 is pressed by the tip 3e of the U-shaped clamping portion 31, and on the lower surface of the shelf board 8, the tip 4b of the shelf board fixing device 3F bites in, so that it is possible to prevent the shelf board 8 from falling off due to bouncing up or the like. And on the tip side of the bracket 2, since the tip 4b of the shelf board fixing device 5F bites into the bottom surface of the shelf board 8 respectively, it is possible to prevent the bracket 2 from swinging left and right. Thereby, it is possible to prevent the displacement of the shelf board 8 and the left and right swinging of the bracket 2.

[0049] When removing the shelf board 8 such as changing the height of the shelf board 8, by lifting the shelf board 8 upward, the shelf board 8 and the tip 4b can be separated. Thereby, by lifting the shelf board 8 and pulling the shelf board 8 forward, the shelf board 8 can be easily removed, and the height of the shelf board 8 can be easily changed.

[0050] In this embodiment, although the shelf board fixing device 5F is also attached to the tip end side of the bracket 2, even if the shelf board fixture 5 on the tip end side is not attached, that is, even if only the shelf board fixing device 3F is attached to the rear end side, it is possible to prevent the shelf board 8 from falling off. However, for preventing the left and right swaying of the bracket 2, only the tip 4b of the rear shelf board fixture 3 functions, so the effect of preventing swaying is slightly reduced compared to the case where the shelf board fixture 5 is attached to the tip end side.

[0051] Although the above-described embodiment has been described for the case of use in a display shelf device for a store, the present invention can be applied not only to stores but also to shelf devices used in various places such as offices and houses.
