2. Description of the Related Art A cabinet for mounting a heavy object such as a television, a stereo set, a CD player, etc.
In particular, it is necessary to have high rigidity. Actual Kaihei 1-162
No. 579 describes a cabinet made of a wooden plank. A cabinet made of a wooden plank generally has high rigidity.

However, cabinets made of wooden planks have high rigidity, but are heavy in weight and disadvantageous in handling and other aspects.
A cabinet made of a hollow plate as disclosed in Japanese Patent Publication No. 41 is also used.

[0004]

By the way, the conventional hollow-panel cabinet has a low mounting strength due to the nature of the hollow plates constituting the respective surfaces thereof. Cabinets with sufficient rigidity cannot be obtained, and many of them are easily bendable. In particular, they are not satisfactory as cabinets for carrying heavy equipment such as televisions, stereo sets, and CD players. Was.

[0005] The present invention is intended to solve the above-mentioned problems, and even if it is constituted by a hollow panel to reduce the weight, it is possible to assemble each panel firmly. It is an object of the present invention to provide a cabinet which has high rigidity and can be easily assembled and disassembled.

[0006]

Means for Solving the Problems The present invention is constituted as follows as technical means for achieving the above object. That is, the top panel, the bottom panel, the left and right side panels,
The upper panel is formed with a substantially U-shaped frame that supports each panel on the inner side. A concave portion is formed on the inner surface of the top panel to fit the horizontal portion of the frame, and the vertical portions of the frame are formed on the inner surfaces of the left and right side panels. The horizontal part of the frame is fitted and fixed to the concave part of the top panel, and the lower end of the frame is fixed to the inner surface of the bottom plate. The cabinet is characterized in that left and right side panels are sandwiched and fixed between the top panel and the bottom panel while fitting the recesses of the panels.

[0007]

According to the cabinet of the present invention, the top panel, the bottom panel, and the left and right side panels are formed of hollow bodies, but the top panel and the bottom panel are connected by two frames, and the left and right side panels are connected. As it is supported by the frame and sandwiched and fixed between the top panel and the bottom panel,
The assembly as a whole is firm, and the rigidity as a cabinet is large. Since the inner surface of each panel is supported by the frame, the load resistance on the upper surface and the deflection resistance in the horizontal direction are particularly large.

The cabinet 1 is shown in FIGS.
And as shown in FIG. Reference numeral 7 denotes a substantially U-shaped frame, and two identical frames are used. These two frames 7 are made of metal pipes. Bottom panel 3
Are provided with four concave portions 8 into which the lower ends of the two frames 7 are inserted and fixed. The inner surface of the top panel 2 is formed with a concave portion 10 into which the horizontal portions 9 of the two frames 7 fit, and the inner surface of the left and right side panels 4 is formed with a concave portion 12 into which the vertical portions 11 of the two frames 7 fit. Are formed. The left and right side plates 4 have a shape in which both front and rear ends are bent inward, and a convex portion 13 is formed at an upper end of the left and right side plates 4. A fitting recess 14 is formed in the top panel 2 with respect to the projection 13. Similar projections are formed at the lower ends of the left and right side plates 4, and concave portions 15 are provided at the left and right ends of the bottom panel 3 to which the projections at the lower ends of the side plates 4 fit. The caster 6 has a shaft portion 16 and a flange portion 17 to be inserted into the frame 7 of the bottom panel 3. The caster 6 is inserted into a hole 18 provided on the lower surface of the bottom plate 3 in correspondence with the hole 8. The shaft part 16 is inserted and mounted. The bottom plate 3 is provided with a fitting recess 19 into which the flange 17 of the caster 6 is fitted.

The cabinet 1 is assembled by first fitting the horizontal portions 9 of the two frames 7 into the recesses 10 of the top panel 2,
The two frames 7 are fixed to the top panel 2 with bolts 20. Reference numeral 21 denotes a buried nut on the top panel 2 side. Next, the lower ends of the two frames 7 are inserted and fixed in the concave portions 8 of the bottom plate 3, and in the process, the concave portions 12 of the left and right side panels 4 are fitted into the vertical portions 11 of the two frames 7 and The left and right side panels 4 are sandwiched between the bottom panel 3 and the upper-side convex portion 13 is fitted into the concave portion 14, and the lower-side convex portion is fitted into the concave portion 15. Then, the side panel 4 is fixed. In addition to the above procedure, the bottom panel 3 and the frame 7 can be fixed, and then the top panel 2 and the frame 7 can be fixed. In this case, the shelf panel 5
Is fitted into the concave portion 22 of the side plate 4, and the back plate 23 is further fitted into the groove 24 of the rear bent portion of the side plate 4 and fixed with screws. The casters 6 are mounted as described above, but the shelf panel 5, the back plate 23, and the casters 6 can be omitted depending on the use of the cabinet.

According to the cabinet 1 of the embodiment configured as described above, the top panel 2, the bottom panel 3, and the left and right side panels 4 are formed of hollow bodies. The left and right side panels 4 are supported by the two frames 7, and the projection 13 and the recess 14 on the upper end side are provided between the top panel 2 and the bottom panel 3.
Further, since the lower end side of the cabinet 1 is sandwiched and fixed by the fitting of the convex portion and the concave portion 15, the assembly as a whole is strong, and the cabinet 1 has high rigidity. And cabinet 1
Since the inner surfaces of the top panel 2, the bottom panel 3, and the left and right side panels 4 are supported by the two frames 7, the load resistance of the upper surface and the bending resistance in the horizontal direction are particularly large.

In the cabinet 1 according to the above embodiment, since the casters 6 provided on the bottom panel 3 are supported at the lower end of the frame 7, the load applied to the top panel 2 is directly transmitted through the frame 7. Castor 6 receives. Therefore, even if a heavy object is placed on the cabinet 1, the cabinet 1 can be prevented from bending. Furthermore, since the left and right side plates 4 are formed with the front and rear ends bent inward, the strength of the side portions of the cabinet 1 is improved. The cabinet 1 is lightweight as a whole because the top panel 2, the bottom panel 3, and the left and right side panels 4 have a hollow double-walled structure made of thermoplastic synthetic resin.

Since the cabinet 1 is assembled sequentially as described above, the cabinet 1 is packed and transported with each member disassembled.
Even if it is sold, the customer can easily assemble and use it at the required place. The assembled cabinet 1 is
To disassemble this, the above-mentioned assembling procedure may be reversed, and the operation is easy.
