Description

[Detailed description of the invention] <<Industrial Application Field>> The invention is an outer frame structure for a cabinet in a desk or the like.

《Conventional technology and problems》 Conventionally, cabinets such as desks are made by bending a single thin steel plate into a square shape, forming the back plate and left and right side plates as one body, and then inserting thin plates above and below between the front ends of the next left and right side plates. The left and right joints made of steel plates are spot welded, and the rail members made of thin steel plates are spot welded vertically at a predetermined interval to create a ladder-like front and rear reinforcing frame material. The front and rear inside surfaces were spot welded to form a box with an open front, and the entire surface of the box was painted to form the outer frame of the cabinet.

For this reason, spot marks remain on the surface of the side panels, resulting in an unsatisfactory appearance, and many processes are required, such as processing of reinforcing materials, spot welding of reinforcing materials, and painting after welding.
Another problem is that the thickness of the reinforcing material must be increased to increase strength.Furthermore, spot welding requires more skill than screwing, and rework due to mistakes in spot welding can be difficult. Taking more time than necessary compared to mistakes etc.
There were many underlying factors that led to increased costs.

[Purpose and structure of the present invention] The present invention provides an outer frame structure for a cabinet in a desk, etc., which has a simple structure using colored steel plates, reduces costs, improves the appearance of the product, and increases strength. with the purpose of
Its structure is such that the front ends of the left and right side plates made of colored steel plates are bent inward into an L-shape to form a fitting part that opens rearward, and the fitting part is made of particle board or synthetic resin. The fitting reinforcing materials are fitted together, and then the upper and lower right and left joining materials made of colored steel plates are screwed to the fitting reinforcing materials and the front end of the side plate, while the rear portion screwed to the inner surface of the rear end of the side plate is screwed to the fitting reinforcing material and the front end of the side plate. The reinforcing material and the fitting reinforcing material are connected by front and rear joint members such as rails.

"Example" The present invention will be explained below based on the drawings.

FIG. 2 shows a perspective view of a desk equipped with the present invention, in which 1 is a top plate, 11 is a left leg that supports the left end of the top plate 1, and 2 is a cabinet that supports the right end of the top plate 1.

The cabinet 2 is composed of an outer frame 3 and a plurality of drawers 21 held within the outer frame 3 so as to be freely accessible.

As shown in FIGS. 1 and 2, the outer frame 3 is made by bending a thin colored steel plate into a letter shape to integrally form a rear plate 31, a right side plate 32, and a left side plate 33, and furthermore, the upper and lower ends of each are bent inward to form rear plate upper and lower bent edges 34, 35, right side plate upper and lower bent edges 36, 37,
In addition to forming the upper and lower bent edges of the left side plate (the left side plate side faces the right side plate 32 side and has the same configuration, only the right side plate 32 side is shown), and the side plates 32, 3
3 is bent inward into an L-shape to form a fitting portion 38 that opens rearward.

Each of the bent edges 34, 35, 36, and 37 has a fitting reinforcing material, which will be described later, and mounting holes 30 for attaching the reinforcing material. Mounting hole 40 for connecting materials
...is formed.

39 is a connecting hole for connecting the top plate 1.

6 is formed into a columnar shape from particle board,
A fitting reinforcing material 61 that tightly fits into the fitting portions 38 of the side plates 32 and 33 is a reinforcing material made of particle board and having approximately the same shape as the fitting reinforcing material 6;
Rear plate upper and lower bent edges 34, 35, side plate upper and lower bent edges 3
6, 37 through the mounting holes 30...
is screwed to the rear end of the

Reference numerals 7 and 7 designate upper and lower left and right joint members, which have an abbreviated cross-section, and include mounting protrusions 71, 71 that protrude rearward and are connected to the front and rear joint members 8 with screws, and that protrude outward from the left and right ends and are connected to the side plates. Connecting protrusions 72... having mounting holes 70 corresponding to the mounting holes 30 formed in the upper and lower bent edges 34, 36, and mounting bent portions 73 located on the left and right end faces and having mounting holes corresponding to the mounting holes 40.
, and the upper and lower end surfaces of the fitting reinforcing material 6 are formed to be slightly smaller than the vertical heights of the side plates 32 and 33, and the side plates 3
Connecting protrusion 7 between upper and lower bent edges 36 and 37 of 2 and 33
2 is inserted and connected to the side plates 32, 33 and the fitting reinforcing member 6 at the same time through the mounting holes 30, 70, 40 with tuft pin screws. 8 are front and rear fitting reinforcing members whose front and rear ends are screwed to the fitting reinforcing member 6 and the rear reinforcing member 61 at a predetermined interval vertically, and in this embodiment, the drawer 21 It also serves as a rail member for...

In the embodiment, the front and rear joint members 8 are also used as the drawer rail members, but if a shelf board is installed in place of the drawer or a net cover is simply provided, the shelf board or shelf support may be used. becomes the front and rear joint member 8.

Further, in the embodiment, an example is described in which the present invention is used in a desk cabinet, but the present invention is not limited to a desk, but can be appropriately modified to a filing cabinet, a side desk, a locker, etc.

In addition, although particle board is used as the fitting reinforcing material in the embodiment, a synthetic resin material may also be formed into a shape that matches the fitting part by extrusion molding, which requires no processing effort. No need to paint
Any material can be used as long as it can be purchased inexpensively and has considerable strength.

《Effects of the present invention》 As described above, the present invention has the following advantages:
It has a simple structure in which the front and rear joint members, etc. are made of thin color steel plates, a fitting part is formed on the front end face of the side plate, and a fitting reinforcing material is fitted to the fitting part, so it is not necessary to use the conventional method. There is no need for bending, spot processing, or caulking of reinforcing materials, and all assembly is done with screws, so no skill is required for assembly work.Furthermore, there is no need for painting after assembly, making it inexpensive. It is a useful device suitable for practical use, as it can be manufactured easily, the overall strength can be increased by the fitting reinforcing material, and it has a very good appearance as no spot marks appear on the surface.
