Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for preventing shelves from falling off, and more particularly to improving an engaging structure between shelves and brackets for supporting the shelves.

[0002]

2. Description of the Related Art A furniture having a shelf board on which various kinds of daily necessities, miscellaneous goods, books, etc. can be placed is generally supported by a bracket whose height position can be adjusted. The shelf board is configured to be supported by the combined structure.

FIG. 11 shows a main part of a conventional furniture. In this figure, a large number of engaging holes 5 are provided along the axial direction.
A bracket 52 made of a plate-shaped piece is supported on the support column 50 having the hole 1 in a state of being oriented in a substantially horizontal direction. At least two of the brackets 52 are arranged along the direction orthogonal to the paper surface in FIG. 11, and the shelf plate 53 is supported on the upper edge side of the brackets 52.

The bracket 52 has three hooks 54 formed on the end edge on the side of the support column 50. When the hooks 54 engage with the lower end edge portions of the engaging holes 51, the bracket 52 is supported. Can be supported by. On the upper edge side of the bracket 52, a plurality of recesses 55 each having a notch shape of a substantially square shape are formed. On the other hand, on the side of the shelf plate 53, an engaging piece 56 formed by vertically cutting and raising a part of the shelf plate 53 is provided, and by engaging the engaging piece 56 in the recess 55, The movement of the shelf plate 53 in the front-rear direction, that is, the left-right direction in the drawing is restricted.

[0005]

However, in the supporting structure of the shelf plate 53 by the recess 55 and the engaging piece 56 as described above, the movement of the shelf plate 53 in the front-back direction is restricted due to its physical shape. Although achieved, the movement of the shelf plate 53 in the rotating direction is not regulated at all, and a person carelessly bumps into the shelf plate 53 on the front side, which is the side opposite to the support column, to the shelf plate 53. Rotational force acts on the shelf plate 53.
However, there is an inconvenience that it falls off from the bracket 52.

[0006] Such inconvenience becomes remarkable in the case of the furniture of the type in which the shelf plate 53 is tilted and supported by the column 50 as shown in FIG. That is, even if the objects to be placed are evenly arranged on the shelf plate 53 supported in an inclined state, a large amount of load is applied to the front side of the shelf plate 53. Depending on how the object to be placed on the shelf plate 53 is placed, the rotation in the R direction in the drawing is always likely to occur. In order to prevent the shelves 53 from falling off due to such rotation, a relatively heavy object is placed on the rear side of the shelves 53, which is the support column 50 side, while the front side is placed on the front side. It is conceivable to place a lightweight object, but in this case, there is the inconvenience of being unable to freely layout the object to be placed.

Further, when the shelf plate 53 is dropped due to rotation, not only the shelf plate 53 itself is damaged but also the object to be placed is damaged, which is used as a display shelf for products and the like. In some cases, it may cause unnecessary damage.

[0008]

SUMMARY OF THE INVENTION The present invention has been devised by paying attention to such a conventional inconvenience, and an object of the present invention is to disperse a load applied to a shelf board and an external force when a person hits the shelf board. A shelf that can effectively avoid the possibility that the shelf board will be rotated carelessly, and that allows a relatively free layout of objects to be placed on the shelf board to further improve the display effect and the like. It is to provide a structure for preventing the plate from falling off.

[0009]

In order to achieve this object, a structure for preventing shelves from falling off according to the present invention is provided with columns which are arranged in parallel with each other with a predetermined interval and height positions of these columns are adjusted. A bracket that is movably supported and has at least one recess formed on the upper edge side, and a shelf plate that is supported between the brackets and that has an engagement piece that is engageable with the recess, Includes an inclined cutout edge extending obliquely downward and forward or rearward from the upper edge of the bracket, and the engagement piece is engaged in the recess along the inclined cutout edge.

[0010]

When a biased load or external force is applied to the shelf board from the front side or the rear side of the shelf board, this gives a force to rotate the shelf board. When such a rotational force is applied, in the present invention, the engagement piece on the shelf side is configured to engage along the inclined notch edge provided in the recess, so that the engagement piece moves to the outside of the recess. There is an inclined region on the virtual movement trajectory when the user tries to do so. Therefore, the movement of the entire shelf board is physically regulated, and consequently, the falling off of the bracket is prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings.

FIG. 1 shows the outer appearance of a main part of a furniture according to an embodiment of the present invention. In this figure, the furniture 10 is entirely formed of a metal material such as steel.
Are pillars 11 arranged in parallel with each other with a predetermined interval.
And a plate-shaped back plate 12 that connects the columns 11 to each other, a pair of brackets 13 that are supported by being engaged with the columns 10, and a pair of brackets 13 that are supported in a state that they are hung between the brackets 13. The shelf board 14 and a base (not shown) are included.

Each of the columns 11 is connected to the back plate 12 via appropriate fixing screws and the like, and a large number of engaging holes 16 are arranged in the vertical direction on the front end face of the columns in the figure. Are drilled at equal pitch.

As shown in the enlarged view of FIG. 2, the bracket 13 is provided with three hooks 17, 18 and 19 at the end edge thereof located on the side of the column 11. Of these hooks 17 to 19, the upper and lower hooks 1
7 and 19, two-stage grooves 17A that enable the bracket 13 to be engaged with the column 11 in a substantially horizontal position and an inclined position,
17B and grooves 19A and 19B are formed respectively. Further, the hook 18 at the central portion is formed with only the groove 18A when the bracket 13 is attached to the horizontal position.

On the upper edge 13A of the bracket 13, three recesses 20 are formed in each of two regions that are separated by a predetermined distance. Each of these recesses 20 has a vertical notch edge 20A that intersects the upper edge 13A at a substantially right angle, a notch bottom edge 20B that extends from the lower end of the vertical notch edge 20A substantially parallel to the upper edge 13A, and a bracket from the upper edge 13A. 13 extends diagonally downward and forward of 13 and the lower end is a notched bottom edge 20B.
And a sloped notched edge 20C that is continuous with. The inclination angle with respect to the upper edge 13A of the inclined notch edge 20C is not particularly limited, and can be arbitrarily set within an angle range in which the later-described rotational movement of the shelf plate 14 can be restricted.

3 and 4 show the detailed structure of the shelf plate 14. As shown in FIG. Here, FIG. 3 shows a rear view of the shelf board 14, and FIG. 4 shows a right side view thereof. In these drawings, the shelf plate 14 is provided so as to be engageable with the bracket 13 by being joined to a substantially rectangular main body plate 22 that constitutes a mounting surface and both longitudinal ends of the main body plate 22, respectively. The engaging plate 23 and a pair of reinforcing bars 24 that are laid between the engaging plates 23 and reinforce the overall strength of the main body plate 22.

As shown in FIGS. 5 to 9, the engaging plate 23 has an elongated horizontal plane portion 26 joined to the back surfaces of the main body plate 22 on both longitudinal ends thereof, and the horizontal plane portion 26 in the widthwise direction. And a slender hanging portion 27 vertically extending from one side edge thereof, and these are formed by bending one piece into a substantially L shape using a single stainless plate material. In the present embodiment, one engaging piece 28 is provided obliquely downward and forward in the middle portion of the horizontal surface portion 26. The engagement piece 28 is formed by continuously cutting three sides of a part of the horizontal surface portion 26 and cutting and raising the remaining one side downward as a hinge portion. The engagement piece 28 is cut and raised at an inclination angle substantially the same as the inclined notch edge 20C of the recess 20, so that the engagement piece 28 can be engaged in the recess 20 along the inclined notch edge 20C of the bracket 13. It has become. The overall planar shape of the horizontal surface portion 28 is not particularly limited as long as the engagement piece 28 is formed at a position where it can engage with the recess 20, and the shape matching with the main body plate 22 on the shelf board 14 is not required. As long as it can be drawn, it can be formed in various planar shapes. By the way, in this embodiment,
An L-shaped notch 29 is formed on the left side of the horizontal surface portion 26 in FIG. 6, but this is for the purpose of conforming the shape with the above-mentioned pillar 11 (see FIG. 1). Is formed on the same surface as the surface of the back plate 12, it is not formed.

The hanging portion 27 of the engaging plate 22 is
With the above-mentioned engaging piece 28 being engaged with the concave portion 20 of the bracket 13 and the shelf plate 14 being supported on the bracket 13,
It covers the outer surface of the bracket 13, and
In some cases, it also acts to regulate the free movement of the shelf plate 14 in the longitudinal direction. The right side of the hanging portion 27 in FIGS. 5 and 6, that is, the front side when the entire shelf plate 14 is supported on the bracket 13 is the end portion 26 of the horizontal plane portion 26.
The tip portion 27A is formed so as to slightly project from A and has a slightly wider plate width in the short width direction, that is, the vertical direction in FIG. As shown in FIGS. 1 and 4, an elongated decorative plate 30 exposed on the front end face side of the shelf plate 14 is supported in the region sandwiched between the front end portions 27A.

The engaging plates 22 form a pair corresponding to the respective brackets 13, and are therefore composed of two kinds of members whose shapes are symmetrical. Further, reference numeral 31 in FIG. 1 shows an example of a fence for preventing a natural fall of an object to be placed.

Next, a method of supporting the shelf plate 14 in this embodiment and its fall-out preventing action will be described with reference to FIGS. 9 and 10.

First, the shelf plate 14 is preliminarily formed by the main body plate 22.
On the other hand, the engaging plate 23, the reinforcing bar 24, etc. are joined at predetermined positions to complete the unit as a single body. On the other hand,
After each pillar 11 is also fixed to the back plate 12, each bracket 13 is supported at an arbitrary height position of the pillar 11. Here, the hooks 17 and 19 of the bracket 13
The outer grooves 17A and 19A of the bracket 13 are engaged with the lower end edges of the engaging holes 16 of the column 11, and the upper edge 13A of the bracket 13 is supported in an inclined state in which it gradually extends downward.

After that, while holding both sides in the longitudinal direction of the entire shelf plate 14 and lowering the shelf plate 14 from a position above the bracket 13 in a slightly inclined state, the shelf plate 14 is cut and raised from the horizontal plane portion 26 of the engaging plate 23. The engagement piece 28
Engage in the recess 20 of the bracket 13. At this time, since the engagement piece 28 is inclined substantially corresponding to the inclination angle of the inclined cut edge 20C of the recess 20, as shown in an enlarged view of FIG. 28 will be located in the recessed part 20 along the inclined notch edge 20C.

With the furniture 10 thus assembled as a whole, a force F1 is applied to the front side of the shelf 14 from the upper side to the lower side, as shown in FIG. 9, for example. Suppose. In this case, the reaction of the force causes the force of F2 to act on the rear side of the shelf plate 14, and the shelf plate 14 as a whole is given a force to rotate in the clockwise direction. At this time, the engaging piece 28
Is present because the inclined notch edge 20C crosses the virtual movement locus of the engaging piece 28 from the relationship of engaging with the concave portion 20 at a position along the inclined notch edge 20C of the corresponding concave portion 20. Therefore, the movement in the rotation direction is physically prevented, and thus the entire shelves 14 are prevented from falling off.

Therefore, according to such an embodiment, the inclined notch 20C is formed in the recess 20 of the bracket 13, and the engaging piece 28 engageable in the recess 20 is formed along the inclined notch 20C. Since it is formed on the side of the shelf plate 14, rotation of the shelf plate 14 that may occur when an external force is applied to a position biased with respect to the shelf plate 14 is effectively prevented, and thus the shelf plate 14 is prevented from coming off from the bracket 13. The effect is that it can be prevented.

Moreover, since the shelves 14 can be prevented from falling off, the object to be placed on the shelves 14 does not drop when the shelves 14 fall off. Therefore, for example, the furniture 10 of the present embodiment is a store. It is possible to eliminate the inconvenience that the product value is lowered due to the drop when it is adopted as a display shelf. In particular, when the object to be placed includes a relatively fragile object such as a glass product, the effect becomes more remarkable.

Further, according to the falling-off preventing structure, the restriction that the relatively heavy object to be placed must be placed on the rear portion of the shelf 14 is not necessarily imposed,
Therefore, a great degree of freedom can be provided in the layout of the placement target object, and the display effect when used as a product display shelf can be further improved.

Further, in the structure of this embodiment, in comparison with the conventional structure, the notch shape of the recess 20 in the bracket 13 is slightly changed, and the corresponding engaging piece 28 is formed on the shelf plate 14 side. In addition to the above-mentioned effects, it is possible to provide a drop-out prevention structure with the same manufacturing cost as the conventional product without difficulty.

Although the inclined notched edge 20C of the concave portion 20 in the above embodiment extends diagonally downward and forward from the upper edge 13A of the bracket 13, instead of this, the inclined notched edge 20C extends obliquely downward and rearward. May be. When the inclined notched edge 20C is provided obliquely downward and rearward, there is a practical advantage particularly in order to prevent the shelf 14 from falling off when the shelf 14 is supported horizontally or at a small inclined angle. In addition, the concave portion 20 of the bracket 13
The vertical edge portion 20A is formed on the
A does not necessarily need to be provided. However, when the vertical edge portion 20A is provided, the concave portion can be effectively used even when the shelf plate provided with the engaging pieces in the vertical direction is a support target, and the versatility thereof is improved. It is advantageous in securing.

Further, the illustrated bracket 13 has three recesses 20 formed in each of the two regions thereof, but the number and position of these recesses 20 are determined by the number of the recesses 20 to be supported.
It is determined by the relative relationship with the size of 4 or the like. Further, the number of the engaging pieces 28 that engages with the recess 20 is not limited to one, but it is possible to add more as appropriate and the shelf plate 14
It is also possible to provide a separate engaging piece that is cut and raised in the vertical direction.

Further, in the above embodiment, the bracket 13 is supported in an inclined state with respect to the column 11, and
Although the shelf plate 14 is also illustrated and described as being tilted and supported,
The present invention is not necessarily limited to this. For example, it goes without saying that the bracket 13 is supported with its upper edge 13A oriented in a substantially horizontal direction, and the shelf plate 14 is also supported horizontally with the bracket 13. However, in the case of supporting the shelf plate 14 in the horizontal direction, even if the object to be placed is arranged so as to give a biased load on the shelf plate 14, the falling of the shelf plate 14 due to this will not occur. It is considered that this does not occur in practice, but when a person carelessly bumps into the shelf 14, an external force that can fall off is exerted, which would be useful in preventing fallout in this case.

Although the furniture 10 is made of a metal material such as steel as a whole, this material is not essential for carrying out the present invention. For example, it may be partially or wholly made of wood or synthetic resin, or any combination thereof, which may also provide furniture with different textures with the above-mentioned structural features. In short, the present invention is based on the bracket 13
As long as a structure for preventing the falling off between the rack and the shelf board 14 is adopted, various design changes of other components may be made.

[0032]

The present invention is constructed as described above, and
According to this, according to this, variations in the load applied to the shelf board and even if an external force that a person hits the shelf board is applied, it is possible to effectively avoid the possibility that the shelf board will fall off the bracket, It is possible to effectively protect the shelf board or objects such as products placed on the shelf board from damage, and
It is possible to provide a shelf plate fall-out prevention structure that has an unprecedented excellent effect that a relatively free layout of an object to be placed is possible and a display effect and the like can be further improved.
