DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for preventing a shelf plate and a bracket of a display device from falling off, and more particularly, to a structure for preventing a shelf plate from being lifted up to prevent the shelf plate from falling off and changing the shelf plate. The present invention relates to a structure that can eliminate the cause of bracket dropout that may occur at times.

[0002]

2. Description of the Related Art In general, a display device having a shelf plate on which various daily necessities, miscellaneous goods, books and the like can be placed has a bracket mounted in a slit hole provided in a support such as a column so that the height of the bracket can be adjusted. The shelf is supported on the bracket via an appropriate engagement structure.

[0003] As a shelf plate and a bracket of a display device,
For example, Japanese Patent Application Laid-Open No. 7-1 already proposed by the present applicant.
No. 94469. Here, the bracket is formed of a piece-shaped member, and a partially cut-out concave portion is provided at an upper edge thereof. On the other hand, the shelf board is provided with side portions joined to both left and right sides of the back surface, and the side portions are provided with engagement pieces formed by partial cutting and raising. The engaging piece can be engaged with the concave portion in an inclined direction, thereby preventing the rear portion of the shelf from being lifted up, and thereby preventing the entire shelf from dropping off.

According to the display device having this configuration, the load applied to the shelves varies, or even if a person hits the shelves, the shelves hardly float above the brackets, and the shelves fall off. It can be solved to a certain extent.

[0005]

However, in the display device proposed in Japanese Patent Application Laid-Open No. 7-194469, when the shelf plate is slightly retracted rearward, the engagement between the engagement piece and the concave portion is reduced. If the shelves do not work effectively and a force is applied to the front side of the shelf board from above in this state, the rear part of the shelf board becomes easy to float, which causes the shelf board to fall off.

The mutual engagement between the engaging piece and the concave portion is as follows.
It is designed mainly to restrict the movement of the shelf in the rotation direction, and is not intended to remove the bracket together with the shelf from the support when the shelf is changed. That is, the already proposed bracket and the shelf board are in an engaged state in which the attachment and detachment between them can be easily performed.
Therefore, when the position of the shelf is changed, if the shelf is not lifted carefully so as to release the engagement between the shelf and the bracket, the engaging piece is caught in the concave portion, and the bracket is placed on the shelf. In many cases, the support slips out of the slit hole of the column while being temporarily held by the plate. In this case, no significant inconvenience occurs if the bracket is always held on the shelf, but in the proposed structure, when the bracket is removed from the support together with the shelf, the engaging piece is oriented in the notch direction of the recess. Therefore, there is a problem that the bracket temporarily held on the shelf side is accidentally detached from the shelf side and falls. Therefore, in many cases, the dropped bracket may damage a product or the like displayed on the base side of the display device, which results in unnecessary loss.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides an engaging piece which can be engaged with a concave portion provided on an upper edge side of a bracket on a shelf board side, and has an The present invention employs a displacement prevention means capable of stably securing the engagement position with the concave portion, so that the cause of the shelves falling off can be eliminated. In addition, the present invention relates to a size
The bracket can be held firmly by sandwiching the bracket between the brackets, and when the shelf board is removed, the bracket can be always removed integrally with the bracket, thereby solving the above-mentioned problem associated with the bracket falling off.

The engaging piece 28 is cut and raised at substantially the same inclination angle as the hook-shaped notch edge 20 </ b> C of the recess 20, whereby the engaging piece 28 can be engaged in the recess 20 along the hook-shaped notch edge 20 </ b> C of the bracket 13. It has become. The overall planar shape of the horizontal portion 2 6 is not limited in particular as long as the engagement piece 28 is formed in a position capable of engaging in the recess 20,
Various planar shapes can be adopted as long as the shelf plate 14 and the main body plate 22 can be matched in shape.
Incidentally, in this embodiment, L on the left side in FIG.
A notch 29 in the shape of a letter is formed for the purpose of achieving a shape matching with the above-mentioned support 11 (FIG. 1).
If the support 11 is on the same plane as the surface of the back plate 12, it will not be formed.

The hanging lower surface portion 27 as the one-sided portion is provided outside the bracket 13 in a state where the above-mentioned engaging piece 28 is engaged with the concave portion 20 of the bracket 13 and the shelf board 14 is supported on the bracket 13. It is located so as to partially cover the side surface. In addition, the side portion 23 also has an action of restricting free movement of the shelf 14 in the longitudinal direction.

A tongue piece 30 cut and raised in a manner similar to that of the engagement piece 28 hangs at a substantially middle portion of the horizontal surface portion 26. As shown in FIG. 5, the tongue piece 30 and the hanging surface 2
7 is equal to or slightly larger than the thickness of the bracket 13, so that the bracket 13 can be press-fitted between the tongue piece 30 and the hanging surface 27, and the bracket 13 is It is possible to pinch with a stronger force than in the thickness direction. Here, the tongue piece 3
The holding means is constituted by 0 and the portion of the hanging surface 27 facing the same. In the hanging surface portion 27, a protruding portion 31 formed by cutting is provided at a position that is located forward of the tongue piece 30. A hole 32 is formed in a portion of the bracket 13 opposed to the projecting portion 31, and the projecting portion 31 is inserted into and engaged with the hole 32, and the side portion 23, and thus the shelf plate 14 and the bracket 13 are connected to each other. A displacement prevention means for restricting relative movement is provided.

The side portions 23 form a pair corresponding to the brackets 13, and are therefore constituted by two types of members whose shapes are symmetrical.

Next, a description will be given of a method of supporting the shelf board 14 in this embodiment and an action of preventing the shelf board 14 and the bracket 13 from falling off.

First, the shelf board 14 is
On the other hand, the side portions 23 and the reinforcing bars 24 and the like are joined at predetermined positions and completed as a single unit. On the other hand, each strut 1
After fixing 1 to the back plate 12, each bracket 13 is supported at an arbitrary height position of the support column 11.

Then, when the shelf plate 14 is pushed downward so that the bracket 13 is sandwiched in the gap between the hanging surface portion 27 of the side portion 23 and the tongue piece 30, the bracket 13 is firmly held. Next, when the shelf board 14 is pulled toward the near side, the protruding portions 31 enter the holes 32 of the bracket 13,
At this time, the engagement piece 28 reaches the engagement position where it comes into contact with the hook-shaped notch edge 20C of the concave portion 20.

When the shelf 14 is removed to change the position of the shelf 14 from the state in which the shelf 14 is supported at a predetermined position, the user lifts the left and right side portions 23 and lifts it slightly and pulls it forward. The hook 17 of the bracket 13
Escapes from the slit hole 16, and the shelf 14 can be remounted at a different height.

The shelf board 14 is engaged with the concave portion 20 at a position where the engaging piece 28 formed on the side portion 23 is in contact with the hook-shaped notch edge 20C of the concave portion 20. Since the protruding portions 31 are engaged with the holes 32 to prevent the shelf plate 14 from being displaced in the front-rear direction, a force from above may be applied to the near side of the shelf plate 14. Never fall off.

In the above embodiment, the shelf 14 is
Although the side portion 23, which is a separate member, is configured to be joined to the main body plate 22, the present invention is not limited to this, and by changing the end bending structure of the main body plate 22, The shape can be substantially the same as the side portion 23.

Further, the means for preventing displacement is provided with a protrusion 3
1 may be provided on the side portion 23 side, and the hole 32 may be provided on the bracket 13 side, or the positional relationship may be reversed.

Further, the number of the tongue pieces 30 is not limited to one, but may be provided at a plurality of places at appropriate intervals, and the bracket 13 may be sandwiched between the plurality of places. An engaging piece separate from the engaging piece 28 is also provided at a position in front of the side portion 23, and the engaging piece is provided in a concave portion 20 provided in front of the bracket 13.
Can be adopted.

[0031]

As described above, according to the present invention,
A projection 31 is provided on the side portion 23, and a hole 32 capable of receiving the projection 31 is formed in the bracket 13 to constitute a means for preventing the position of the shelf board 14 from being shifted. The mutual engagement position between the recess 28 and the recess 20 is kept constant, and the lifting of the shelf 14 is physically restricted, so that the shelves 14 can be effectively prevented from falling off.

Further, a gap is formed between the tongue piece 30 and the hanging surface 27 as a piece adjacent to the tongue piece 30 so that the bracket 13 can be strongly inserted.
Therefore, even if the shape of the existing side member is slightly changed, the bracket can be held very effectively. Therefore, when the removal of the shelf plate 14, the shelf plate 14 can always be maintained in a state holding the bracket 13, an effect that Ru can eliminate the possibility that only the bracket 13 from falling upon removal of the shelf plate 14 obtain.
