Description

[Detailed Description of the Invention] Conventional display fixtures have been equipped with a fall prevention mechanism to prevent the display from falling if a person steps on the front end of the bottom shelf.

However, the above-mentioned fall prevention mechanism has a drawback in that it has a complicated structure and requires time and effort during construction.

In view of the above-mentioned points, it is an object of the present invention to provide a shelf board mounting structure that not only has a simple structure and can reliably prevent overturning, but also allows easy attachment and detachment of the final shelf board.

Embodiments of the present invention will be described in detail with reference to the drawings.

Reference numeral 1 denotes a hollow, prismatic steel horizontal piece, with prismatic legs 2 integrally extending from the front and rear ends of the lower surface of the horizontal piece 1, and a corner extending from the rear end of the upper surface of the horizontal piece 1. Column-shaped supports 3 are integrally extended to form a hollow steel frame 4 as a whole.

Further, two rectangular through holes 5a and 5b are provided on the upper surface of the front and rear ends of the horizontal piece 1 so as to communicate with the internal space of the horizontal piece 1.

Reference numeral 6 denotes a channel member which is an elongated member with a lower surface opening and a U-shaped cross section, and an abbreviated-shaped member is formed on the lower surface of the central horizontal portion 20 of the channel member 6 at a position corresponding to the through holes 5a and 5b. A key-shaped piece 7 and a flat protruding piece 8 are vertically provided in a direction perpendicular to the longitudinal direction of the groove-shaped member 6.

The key-shaped piece 7 has an L-shape composed of a vertical piece 7a and a horizontal piece 12 extending rearward from the lower end of the vertical piece 7a, and as shown in FIG. 7 to the rear through hole 5a
The vertical piece 7a approaches the rear edge of the through hole 5a and the horizontal piece 12 protrudes rearward from the lower surface side of the rear edge of the through hole 5a. A groove-shaped member 6 is placed on the upper surface of the horizontal piece 1 so as to fit into the front end edge and accommodate the horizontal piece 1 in the opening of the groove-shaped member 6.

At this time, the rear end of the channel member 6 has a predetermined gap with the support 3,
On the other hand, the front end of the channel member 6 is arranged so as to protrude forward from the front end of the horizontal piece 1.

In addition, a fitting protrusion 21 having a U-shaped cross section is fixed to the front and rear ends of the upper surface of the central horizontal portion 20 of the groove member 6 with an opening on the upper surface.

A plurality of frames 4 as described above are arranged side by side to constitute the framework of display fixtures, and display shelves are horizontally hung between adjacent frames 4, as shown in Figure 2. Downward protrusions 10 whose lower ends are free ends provided on the side edges of the lowermost shelf boards 9a and 9b adjacent to the lowermost shelves 9a and 9b are respectively positioned and fitted into the openings 11 of the fitting protrusions 21.

That is, as shown in Fig. 1C, there are a steel shelf board 9a and a wooden shelf board 9b.
In this case, a hanging piece 10a provided on the side edge forms a downward protrusion 10 whose lower end is a free end.

In addition, in the case of the wooden shelf board 9b, the fitting protrusions 21 at the front and rear side ends
By providing the recesses 10b at positions corresponding to the recesses 10b, the portion between the outer wall of the recess 10b and the side surface of the wooden shelf board 9b becomes a downward protrusion 10 whose lower end is a free end. Therefore, it is fitted into the opening 11 of the fitting protrusion 21.

In FIG. 2, the outer surface of the hanging piece 10 of the steel shelf board 9a and the side surface of the wooden shelf board 9b are fitted in contact with each other within the opening 11 of the mounting bracket 21.

Of course, the wooden shelf board 9b or the steel shelf board 9a may be used together, so the fitting protrusion 21 can be connected to the wooden shelf board 9a.
The opening width is such that it can be inserted into the recess 10b provided in the recess 10b, and the opening width is such that the side surfaces of the two wooden shelf boards 9b can be inserted into the recess 10b in contact with each other.

Further, a support arm is locked into a locking hole 14 opened in the front face of the support column 3, and a plurality of display shelves are supported by the support arm.

Note that 15 is a height adjustment screw.

Then, the key-shaped piece 7 is inserted into the rear through-hole 5a, the groove-shaped member 6 is shifted rearward, and the rear surface of the bent part 12 of the key-shaped piece 7 is inserted into the through-hole 5a.
After contacting the rear end edge of a, the front through hole 5b of the protruding piece 8
The groove member 6 is engaged with and placed on the upper surface of the horizontal piece 1 so as to wrap around the horizontal piece 1.

Then, a plurality of frames 4 formed as described above are arranged side by side, and the downward protrusions of the adjacent lowermost shelf boards 9a, 9b are fitted into the openings 11 of the fitting protrusions 21 to form the adjacent frames. 4,4
Shelf boards 9a and 9b are supported between them, and other shelf boards are arranged above to form display fixtures.

When the final stage shelf boards 9a and 9b are not used, the shelf boards 9a,
The channel member 6 can be easily removed from the horizontal piece 1 by simply removing 9b, lifting the tip of the channel member 6, and shifting it forward.

The final stage shelf boards 9a and 9b can be made of wood or steel, or even if they are used in combination, they can be fitted into the fitting protrusion 21.

Even if a person gets on the tip of the shelf 9b, the key-shaped piece 7 of the groove member 6 will stop the rotation moment of the shelf 9a, 9b, and the shelf 9a, 9b will be stopped.
will not rotate and fall as shown by the arrow in Figure 2a.

In this way, since the present invention is structured like a narrative,
Insert the key-shaped piece into the rear through-hole, shift the groove-shaped member backwards so that it abuts the key-shaped piece, and then insert the projecting piece into the front through-hole so that the groove-shaped member wraps around the horizontal piece. The shelf board can be supported between the frames simply by placing a channel member on the top surface of the horizontal piece and fitting the shelf board to the fitting protrusion. Moreover, when the bottom shelf board is not in use, the groove The channel section can be removed from the horizontal piece by simply lifting the tip of the section and moving it forward, making it easy to attach and remove the shelf, and the shelf does not get in the way when not in use. It is very easy to use.

Furthermore, when a person steps on the tip of the bottom shelf, the rotational moment generated in the bottom shelf is stopped by the locking part between the key-shaped piece of the channel member and the rear through hole, and the shelf board is rotated. A reliable fall prevention mechanism can be constructed with a simple structure without falling.
