Description

[Detailed Description of the Invention] This invention relates to a guard device for a shelf installed in a kitchen or the like.

[Conventional technology]

When the shelf board is made of a metal plate, guard devices are installed along the four sides of the shelf board in order to prevent articles from falling off the shelf board.

As such a guard device, for example,
-There is one disclosed in Publication No. 40831. In this device, a guard made of metal wire bent along the four sides of the shelf board is fitted to both ends of the shelf board using a pair of supporting metal fittings.

The above guard device wraps the upper end of the support fitting around the guard, forms an inward U-shaped fitting groove below it, and uses the elasticity of the support fitting to extend the fitting groove to both ends of the shelf board. It is installed by fitting the

[The problem that the idea attempts to solve]

However, since the guard device with the above structure has the upper end of the support fitting wrapped around the guard,
The support fitting rotates freely around its wrapped portion. Therefore, if there is a gap in the fitting portion between the fitting groove and the shelf board, the support fitting will be in a state where it is easy to rotate outward around the guard. If external force or vibration is applied in such a state, there is a drawback that the guard device easily comes off.

In order to eliminate such drawbacks, high accuracy is required in the dimensions of the fitting groove of the support fitting and the thickness of the shelf board, and the fitting gap must be made as small as possible. There is also the inconvenience of having to use support metal fittings of different standards depending on the thickness of the shelf board.

Therefore, the object of this invention is to solve the above-mentioned problems and provide a shelf guard device with excellent installation stability and adaptability.

[Means to solve the problem]

In order to achieve the above object, this invention bends a metal wire into a shape along the four sides of the shelf board to form a rectangular guard, and installs supporting metal fittings on both end sides of the guard. In a shelf board guard device that is attached to a shelf board, the support fitting is provided with a bent part that rests on the end of the shelf board, and a support part that is bent downward at a right angle from the bent part, and the support part is provided with A protruding protrusion is provided, engagement holes for the protrusion are formed on both end faces of the shelf board, and L-shaped support pieces are cut and raised into which the lower ends of both sides of the support fitting can be tightly fitted. This is what I did.

[Effect]

Insert the lower end corner parts of the support bracket into the grooves of the L-shaped support piece of the shelf board, and push it down.The protrusions of the support bracket will fit into the engagement holes of the shelf board, and the bent portions of the support bracket will fit into the shelf board. It is installed so that it rests on the top surface of both ends.

〔Example〕

Figure 1 is an example of a draining shelf. Shelf board 1 in this case
consists of a combination of a pipe shelf 2 and a metal flat plate shelf 3, the flat plate shelf 3 has four sides bent up and down, and the pipe 5 of the pipe shelf 2 is inserted into one end face 4, and the pipe shelf 2 is The ends are integrally connected by screws 6 inserted from the side of the flat plate shelf 3.

On the end surface 4 of the flat plate shelf 3, a pair of L-shaped support pieces 7 (see FIG. 2) are provided by cutting and raising and facing each other on both sides of the central pipe 5. Each support piece 7 has an engagement groove 8 that is vertically open between the support piece 7 and the end surface 4 of the flat plate shelf 3 on its opposing inner side. In addition, each support piece 7 and the above-mentioned pipe 5
An engagement hole 9 is provided between the two.

On the other hand, the guard 10 is formed into a rectangular frame shape along the four sides of the flat shelf 3 by bending a metal wire, and has supporting metal fittings 11 made of metal plates attached to both ends thereof.

As shown in FIG. 2, the upper end of the support fitting 11 is
It is wound around the guard 10 by the winding portion 12 .
Further, a bent portion 13 bent outward at a right angle is provided in the middle of the support fitting 11, and the bent portion 13 is further bent downward at a right angle to form a support portion 14.

The support part 14 has a recessed part 15 formed at the lower side of its center, and is made to straddle the pipe 5 described above. Further, on both sides of the recessed part 15, a rectangular bulged part 16 protruding from the inner surface of the support part 14 by an amount equal to the thickness of the plate.
Further, an engaging protrusion 17 is provided at the center of the bulged portion 16 so as to protrude in the same direction. This protrusion 17 is formed in a size that can fit into the engagement hole 9, and is located at a position where it fits into the engagement hole 9 when the bent portion 13 is placed on the upper surface of the flat shelf 3. established in

Note that the width w of the engagement groove 8 of the support piece 7 described above (the third
(see figure) is set to about twice the plate thickness of the support metal fitting 11.

The above-mentioned guard 10 is a support part 1 of a support fitting 11.
4 to the engaging grooves 8 of each support piece 7.
and press downward. As a result, the rectangular bulge 16 reaches above the engagement hole 9 and presses its inner surface against the end surface of the shelf board 1, and also presses the outer surface of the support portion 14 against the inner surface of the support piece 7. resistance. When the support fitting 11 is further pushed in, the bent portion 13 rests on the upper surface of the flat shelf 3, and the engagement protrusion 17 fits into the engagement hole 9, as shown in FIG.
Moreover, the recessed part 15 straddles the pipe 5 (see the lower shelf board 1 in FIG. 1).

When the guard 10 is attached as described above, the guard 10 is provided at a constant height along the four sides of the flat shelf 3.

Note that when removing the guard 10, remove the support fitting 11.
When the protrusion 17 is pulled slightly upwardly, the protrusion 17 slips out of the engagement hole 9 and comes off.

[Effect of idea]

As mentioned above, the guard device of this invention is installed by engaging the support metal fittings with the engagement grooves of the support pieces formed on the end faces of the shelf boards, so that the position of the guard in the front and back direction is adjusted by the engagement. is fixed and also prevents the support fitting from rotating outward about the guard. Furthermore, the engagement between the protrusion and the engagement hole prevents the support fitting from coming off upward. Therefore, the support metal fittings do not come off due to vibration or normal external force, and are highly stable.

Further, since the structure of the support fittings is independent of the thickness of the shelf board, it is convenient that the support fittings having the same structure can be used even if the thickness of the shelf board changes.

Note that if the protrusion is provided at the center of the bulge as in the example, the height of the cut-out of the support piece increases by the height of the bulge, so the opening of the engagement groove of the support piece increases. The width becomes larger. Therefore, the lower both corner portions of the support portion can be easily inserted into the engagement groove.
