Description

[Detailed description of the invention] The present invention is concerned with improving the structure of cabinets such as sinks, especially the installation of beams interposed between the groin part and the back plate, and reduces the number of beam materials and improves the installation. The idea was to save time and improve productivity.

Conventional cabinets such as sinks have a beam installed at the bottom that is divided into two parts, an upper and a lower part.One part serves as a support for storage boxes, etc. that is attached to the top part, and the lower part serves as a support part for the back plate and the bottom part. Its role was to maintain a constant distance between the two.

Each of these beams was fixed at both ends with fasteners such as screws.

Therefore, the number of fastening points increased, and the fastening work at the rear of the beam was difficult, resulting in very poor productivity.

This invention uses one beam to perform the role that was previously performed by two beams.

In addition, the disadvantages of the prior art are overcome by reducing the number of fastening parts such as screws.

One embodiment of the present invention will be described below based on the drawings.
2 is the top plate of the sink, 2 is the rear plate, and a protrusion 2a with an inverted U-shape on the side is formed at the bottom to be approximately at the same height as the indented part 4, which will be described later.
An upright piece 2b is formed at the lower end by bending it into a substantially U-shape.

3 is the side plate, 4 is the cutout, 5 is the front frame, each of these parts 1
, 2, 3, 4.5 are connected to form a cabinet.

Reference numeral 8 denotes a storage box provided in the cabinet 6, and 9 a beam connecting the rear plate 2 and the relief part 4, which also serves as a support for the storage box 8.

As shown in FIGS. 2 and 3, this beam 9 is formed into a wide rectangular plate shape, and its upper and lower edges are bent approximately horizontally, and a projection protruding rearward is formed on one end, that is, on the rear plate 2 side, and on both the upper and lower edges. Pieces 10 and 11 are provided.

The upper projecting piece 10 is formed by extending a horizontally bent horizontal piece 12, and the lower projecting piece 11 is formed by extending a part of the vertical part of the beam 9. A portion of the protrusion piece 10 is provided with a protrusion 13 that is notched and protrudes downward.

Further, at the other end of the beam 9, that is, at the upper edge on the side of the recessed portion 4, a projecting piece 14 is formed by extending the horizontal piece 12 as it is.

On the other hand, a corner hole 15 whose opening height on the vertical side is approximately the thickness of the protrusion 10 is provided at the upper corner of the beaded strip 2a of the rear plate 2 to which the beam 9 is fixed, and a corner hole 15 is provided at the lower end of the rear plate 2. A notch hole 16 is formed in the upright piece 2b and the top surface is open.

In the above structure, the beam 9 is constructed by first inserting the protrusion 10 of the beam 9 into the hole 15 of the rear plate 2 so that the protrusion 13 is deeper than the edge of the hole, and then inserting the other protrusion 11. Insert into the notch hole 16.

Then, the other end projecting piece 14 of the beam 9 is attached to the horizontal part 4' of the support 4.
The beam 9 may be placed on the beam 9 and fixed with fasteners 17 such as screws, thereby completing the installation of the beam 9.

At this time, the beam 9 only needs to be fastened at one place as described above, and this fastening can be easily done from the top surface of the recessed portion 4.

Further, since the beam 9 engages with the rear plate 2 through the upper and lower protrusions 10 and 11, it becomes like two beams are provided, and there is no need to provide two beams as in the conventional case.

In addition, since the square holes 15 and notch holes 16 on the rear plate 2 side are open at the top, they can be easily inserted and fitted from diagonally upward while looking at both holes 15 and 16, regardless of the cutout 4 at the lower front of the cabinet. Then, the rear plate 2 side.

Since the upper protruding piece 10 is inserted and fitted so as to be in contact with the inner surface of the upper wall of the protruding portion 2a, it is possible to prevent the upper protruding piece 10 from tilting due to contact with the inner wall surface and from shaking.

In addition, since the lower projecting piece 11 on the rear plate 2 side is a rigid vertical piece that extends the vertical part of the beam, the load applied to the beam 9
Problems such as the upper protruding piece 10 on the side deforming and falling off do not occur, and furthermore, the upper protruding piece 10 on the rear plate 2 side is provided with a protrusion 13 that is partially cut out and protrudes downward. The punch will not fall due to deflection of the rear plate 2, etc.

As described above, the present invention has the following effects.

1. Since one beam performs the functions of two conventional beams, the number of parts is reduced.

2. One side of the beam can be fastened without using fasteners such as screws, and the front part of the other side can be fastened in one place, and the fastening is from the top, improving productivity compared to conventional methods.

3. Since the square holes and notch holes on the rear plate side are open at the top, the cabinet can be easily inserted and fitted from diagonally upward while looking at both holes, regardless of the dents on the lower front of the cabinet.

4. Since it is inserted and fitted so as to contact the inner surface of the earthen wall of the upper protrusion on the rear plate side, it tends to tilt due to contact with this inner wall surface,
It can prevent backlash etc.

5. Since the lower protruding piece on the rear plate side is a rigid vertical piece that extends the vertical part of the beam, there is no problem such as the upper protruding piece on the rear plate side deforming due to the load applied to the beam and falling off.

6. The upper protrusion on the rear plate side is partially cut out and has a protrusion that protrudes downward, so the drawer will not fall off due to deflection of the rear plate.
