【Example】

 Next, an embodiment embodying the present invention will be described. The cabinet 1 of the present invention is made of a thin metal plate, and is composed of a bottom plate 2, a top plate 3, left and right side panels 4, 4 and a rear panel 5 which are separately formed. Reference numeral 6 is a base body fixed on the floor with anchor screws 7. The base body 6 has a longitudinal downward U-shaped cross-section fitting portion 6a, 6a having substantially the same length as the dimension of the cabinet 1 in the front direction. Are connected by a flat plate portion 6b, and an adjuster base 8 having a U-shaped cross section is similarly fitted and inserted below the end of each fitted portion 6a. The shaft portion 9b of the adjuster bolt 9 that is screwed into the adjuster base 8 is made to face upward from the insertion portion 6c that is cut out in the end face of the fitted portion 6a in a substantially semicircular shape in plan view, and is attached to the head portion 9a of the adjuster bolt 9. The baseboard 10 which is long in the front direction to be placed is fitted onto the outer periphery of the fitted portion 6a. The cabinet 1 is placed on the skirting boards 10, 10 before and after this. When the cabinets 1 are arranged horizontally, a corresponding number of base bodies 6 are arranged side by side. In that case, the side panel 4 at the intermediate position is shared by the left and right cabinets 1 (see FIG. 7).

Reference numeral 11 is a fixed frame for positioning the end of the base body 6, reference numeral 12 is a horizontal skirting covering the outside thereof, and each cabinet 1 has an opening / closing door 13, a drawer 14, etc. Various forms can be attached as desired. The left and right substantially central portions of the surface plate 13a of the opening / closing door 13 are bent inward to form a concave portion 15, and a separate decorative plate 16 is fitted into the concave portion 15. At this time, upper and lower cover plates 17 (only the upper ends are shown in FIG. 4) are fixed to the upper and lower ends of the opening / closing door 13 by spot welding or the like. The upper and lower cover plates 17 are provided with protrusions 17a for preventing the decorative plate 16 from falling off, and the decorative plate 16 is curved vertically and inserted into the recess 15 (see FIG. 4). An adhesive may be applied to the back surface of the decorative plate 16 before the insertion, and the decorative plate 16 inserted into the recess 15 may be pressure-bonded.

As shown in FIGS. 5 and 6, the bottom plate 2 and the top plate 3 of the cabinet 1 are formed by bending the front edge of the flat plate portion 18 at a right angle and bending the ends thereof into an L shape. It consists of a side plate part 19 and left and right side plate parts 20, 20 that are bent at right and left side edges of the flat plate part 18 at right angles, and a reinforcing rib 21 having a left and right longitudinal direction is fixed by spot welding to a middle part of the inner surface of the flat plate part 18. To do. The bottom plate 2 and the top plate 3 are also provided with locking edge plates 22 which are long in the left-right direction and which are formed by bending the rear end edges of the flat plate portions 18 at right angles. Reference numeral 23 is a reinforcing frame provided on the inner side of the locking edge plate 22 and having an L-shaped cross section, and the inner cover body 24 is detachably fitted into the reinforcing frame 23 and the front side plate portion 19. Reference numeral 25 is a locking claw projecting forward from the front end of the inner cover body 24. It should be noted that the bottom plate 2 may have a large notch in the substantially central portion of the flat plate portion 18 so that the wiring cord can be inserted from the inside of the cabinet into the space with the base body 6 with the inner cover body 24 removed. .

The rear panel 5 is composed of a back plate 26, a decorative plate 27 and a reinforcing member 28 such as a honeycomb member interposed therebetween, and each of the four peripheral plates of the back plate 26 and the decorative plate 27 is cut inward. The back panel 5 is bent in an L shape to form recessed grooves 29 along the longitudinal direction on the four sides of the rear panel 5. Reference numeral 30 shown in FIG. 7 is a vertically extending locking projection for fixing a screw 31 to the inner surface of the rear end of the left or right side panel 4, which is the outermost side panel. 30 has a U-shaped cross section, one side piece 30a serves as a seal for the inner corner portion of the rear panel 5 and the side panel 4, and the other locking piece 30b is the vertical direction of the rear panel 5. It is fitted and locked in the recessed groove 29. Reference numeral 30c is a joint strip portion.

Similarly, the locking projection 32 shown in FIG. 7 is for connecting the side panel 4 and the rear panel 5 at the middle position when the cabinets 1 are arranged side by side, and is made of a synthetic resin. The cross section of the protrusion 32 is substantially cross-shaped, and bifurcated locking claws 33 provided at appropriate intervals in the longitudinal direction on the base are fitted and locked in the recessed grooves 34 on the rear end side of the side panel 4. The pair of left and right locking pieces 32a, 32a are fitted and locked in the vertically elongated recessed grooves 29 in the rear panel 5, respectively.

When the width of the rear panel 5 is small and a plurality of rear panels 5 are connected laterally, the locking projection 35 having a cross-shaped cross section is also used. Further, when the decorative plate 36 is stretched on the inner surface of the rear panel 5, the side edge piece of the decorative plate 36 is pressed by the soft pressing strip 37 protruding from the base of the locking projection 32. In this configuration, in order to assemble the cabinet 1, the side plate portion 20 of the bottom plate 2 placed on the skirting boards 10, 10 on the base body 6 and the one side panel 4 leaned on the skirting board 10 by the operator. The inner surface is abutted and fixed with screws (screws) 38. Next, in advance, the recessed groove 29 on the lower side of the rear panel 5 is formed on the rear end of the inner surface of the one side panel 4 with the screw 31 and the locking projection 30 and the rear end locking plate 22 of the bottom plate 2. Mate at the same time. Further, the locking projection 30 fixed to the rear end of the other side panel 4 (when the cabinets are continuously installed, the locking projection 32 fitted into the recessed groove 34 on the rear end side of the side panel 4) is provided. , The upper and lower vertical recessed grooves 29 on the other side of the rear panel 5 are fitted, and then the rear end locking edge plate 22 of the top plate 3 is fitted into the upper side recessed grooves 29 on the rear panel 5, The left and right side plate portions 20 of the plate 3 are fixed with screws (screws) 38.

According to this structure, the screwing points are only between the bottom plate and the top plate and the side panel, and the upper and lower sides and the left and right sides of the rear panel 5 are all locked by the locking edge plate 20 and the locking groove. The projecting ridges 30 and 32 are engaged with each other, so that the assembling work of the cabinet 1 is extremely simple. Although the locking projections 30 and 32 are formed separately in the above-described embodiment, they may be integrated by bending the side plate of the side panel 4. Further, the intermediate shelves 39 may be fixed to the inner surfaces of the left and right side panels 4 and 4 by screws 38 at the midway height position.

[0013]

[Operation and effect of the device]

 As described above, according to the present invention, the recessed grooves are formed around the upper and lower sides and the left and right sides of the rear panel, and the recessed grooves are formed on the upper and lower sides of the rear panel and the rear end of the bottom plate faces upward. The locking edge plate bent to the bottom and the locking edge plate bent downward to the rear end of the top plate are fitted and locked, respectively, and the left and right side surfaces of the bottom plate and the top plate are screwed to the side panel, Since the upper and lower longitudinal locking projections that are fixedly projected on the inner surface of the rear end of the left-right panel are fitted and locked in the recessed grooves on the left and right sides of the rear panel, they are fixed separately. As compared with the above configuration, the rear panel can be firmly attached.
