Description

[Detailed Description of the Invention] A. Field of Industrial Application The present invention relates to a box structure such as a disk unit formed by combining a cover member and a frame member.

B. Outline of the Invention The present invention relates to a box body of a disk unit in which a cover member and a frame member are combined, and a front frame portion of the cover member is fitted inside a support member of the frame member while a mounting piece of the cover member is attached. By screwing the back plate of the frame member to the inside, the whole is assembled into an integral box shape.

C. Related Art As a conventional disk unit box body, there is a case in which two cover members 1 and 2 are combined as shown in FIG. One cover member 1 is formed by opening the back surface and bottom surface of a rectangular box, and a support plate 3 is installed on the upper opening of the back surface, and the support plate 3 is installed on both sides of the opening of the bottom surface. Respectively form the side support plates 4 integrally.

The other cover member 2 is formed by bending a long plate into an L shape as a whole.
The back plate part 2a and the bottom plate part 2b are integrally formed.

The other cover member 2 is fitted into the opening of the one cover member 1 to assemble into a rectangular box. At this time, a screw 7 is fitted and fastened to the through hole 5 in the upper part of the back plate 2a and the corresponding screw hole 6 of the support plate 3. Through holes 8 are drilled at predetermined four positions on the bottom plate 2b, and the screws 7 are respectively fitted and fastened to the screw holes 9 formed in the two side support plates 4 corresponding thereto. , Is to integrate the whole.

D. Problem to be Solved by the Invention In the conventional box body structure as described above, the total number of screws 7 for fastening one cover member 1 and the other cover member 2 constituting the box body is large, and the bottom plate portion In order to tighten the four screws 7 of 2b, the box body must be turned upside down and the bottom plate portion 2b must be turned up, so that the assembly work is troublesome and difficult.

Further, it is preferable that the screw 7 for fixing the rear plate portion 2a is not exposed to the outer surface from the viewpoint of design, but there is a problem that there is no suitable means for hiding the screw 7.

In view of the above points, the present invention newly provides a box structure in which the total number of screws used when assembling the box is small, the assembling work is easy, and the screws are not exposed on the outer surface of the box. The purpose is to do.

E. Means for Solving the Problems The structure of the present invention for achieving such an object is to form a box body by combining a cover member and a frame member,
The cover member is formed into a substantially inverted U-shaped cross section, a front frame portion is formed in one of the front opening portions, and a mounting piece is provided in the other rear opening portion by being bent inward. The frame member is configured by vertically arranging a support member and a back plate which are framed in a quadrangle at both ends of a bottom plate. The front frame portion of the cover member is fitted inside the support member of the frame member and the cover is provided. The back plate of the frame member is arranged inside the mounting piece of the member, and only the mounting piece and the back plate are screwed.

F. Action To assemble the box body, while fitting the front frame portion of the cover member inside the support member of the frame member, insert the back plate of the frame member into the inside of the mounting piece of the cover member, Fit the frame member inside,
Screw the mounting plate and the back plate together.

G. Embodiment An embodiment of the box structure of the present invention will be described below with reference to FIG. In FIG. 1, parts corresponding to those of the conventional example shown in FIG. 2 are designated by the same reference numerals, and detailed description thereof will be omitted.

FIG. 1 is an exploded perspective view of the box body of this example, in which 10 is a cover member, 11 is a frame member, and 12 is a dust filter.

The cover member 10 is formed by opening a back surface portion and a bottom surface portion of a rectangular box body.

The back opening of the cover member 10 is provided with a mounting piece 10a formed by bending a part of both sides of the cover member 10 so as to project, and a total of four through holes 13 are formed therein.

A front frame portion 14 is formed on the front side portion of the cover member 10. The front frame portion 14 is formed to be slightly smaller than the outer shape of the peripheral side of the cover member 10 so that the front frame portion 14 can be fitted and supported inside the support member 21 of the frame member 11 described later. Each lower corner portion 14a of the front frame portion 14 is formed into a round shape so that the work of fitting the support member 21 can be easily performed.

The frame member 11 is provided between the support member 21 and the back plate 15,
The bottom plate 16 and the beam member 17 are bridged to be integrally formed.

 The front frame portion 14 is formed in a rectangular frame shape.

The bottom plate 16 has a side portion bent to form a reinforcing structure. Back body 15
Has four rectangular small openings 18 in its central portion, and a total of four screw holes 19 in predetermined positions on both lateral sides thereof.

The dustproof filter 12 is provided with projecting pieces on both lateral sides thereof, and mounting screws 20 are attached to the projecting pieces.

 Next, to assemble the box, do the following.

First, the front frame portion 14 of the cover member 10 is fitted and supported on the inner peripheral side of the rectangular recess of the support member 21 on the front surface of the frame member 11. Along with this, the back plate 15 is fitted into the back opening of the cover member 10, and the bottom plate is fitted into the bottom opening of the cover member 10.
Two screws 7 in a box-like combination with 16
Are respectively passed through the through holes 13 and fastened to the screw holes 19.

Next, the dustproof filter 12 is set to a predetermined position that closes the small opening 18, and the two mounting screws 20 are respectively passed through the through holes 13 and the screw holes 19 are provided.
To conclude.

As a result, the heads of the two screws 7 are attached to the dustproof filter 12
This is hidden behind and only the decorative head portion of the attachment screw 20 of the dustproof filter 12 is exposed on the surface of the box body, which can be preferably constructed in terms of external design.

H. Effect of the Invention As described in detail above, according to the box structure of the present invention, the front frame portion of the cover member is fitted and supported inside the support member of the frame member, and at the same time, the cover is located on the opposite side. Since the back plate of the frame member is screwed and fastened to the inside of the mounting piece of the rear opening of the member to form a box body that is wholly integrated, it is possible to assemble using only a very small number of screws. It is possible to use only the back side for screwing position, and it is possible to improve workability by eliminating the troublesome work of turning the box body upside down because the screw is fixed at the bottom position of the conventional box body. By arranging, there is an effect that the head of the screw can be hidden by the dustproof filter to improve the appearance.
