Description

[Detailed Description of the Invention] Industrial Application Field The present application relates to an organization box for organizing documents or storing small items.

BACKGROUND ART Conventionally, a cylindrical outer casing made of a metal plate, a pair of left and right inner wall plates attached to the left and right inner surfaces of the outer casing and having drawer guide bars on their inner surfaces, and the left and right wall plates are provided. There is a well-known arrangement box that is comprised of a drawer that is inserted between the drawers and is received by the guide bar.The outer casing of the known arrangement box is made by bending a metal plate in a downward U-shape, and forming a top plate and a drawer. The left and right side plates are integrally formed, and the front edges of these plates are bent inward in a U-shape to form the edge frame, and the rear edges are bent inward at right angles to form welding margins. is provided to constitute a torso, and
A bottom plate with welding margins on the left and right edges is fitted into the lower opening of the body, and a back plate is fitted into the rear side.
After the parts were attached by spot welding the welding margins, the surface of the outer casing was painted for decoration.

Problems to be Solved by the Invention However, according to the above-mentioned well-known sorting box, when producing the outer casing, it is necessary to spot-weld the bottom plate and the back plate to the body and then apply surface painting. Not only does it have the disadvantage that the outer casing cannot be manufactured using a metal plate with excellent decorative printing, but also the corners of the outer casing have a right angle shape and form the front surface of the outer casing. The frame had defects such as 45° joining marks at the corners, which seriously spoiled the appearance and diminished the product value.

Means for Solving the Problems Therefore, the present application eliminates the welded part of the outer casing, and configures the casing and the edge frame (frame body) that constitute the outer casing separately, so that the front edge and the edge of the cylindrical body By joining the outer periphery of the frame, an outer casing with rounded outer periphery corners and a rectangular front opening for inserting and removing the drawer is constructed, improving the defects of the conventional one. It is.

Embodiments The embodiments of the present application will be detailed below with reference to the drawings.
A is an outer casing made of a metal plate, the surface of which is painted by printing etc. is bent into a rectangular cross-section so that the corners are rounded, and both edges of the metal plate are bent at one corner of the bottom, for example. As shown in FIG. 4, a rectangular cylinder 2 is joined by caulking 1 and has a rectangular tray portion 3 on the top plate 2a.
The front surface thereof is formed into an L-shaped cross section, and the upper edge of the vertical piece is bent outward horizontally to have a joining margin 4a, so that the outer peripheral edge of the cylindrical body 2 is A link-shaped frame 4 having rounded corners and a rectangular inner periphery to fit the inner periphery.
The front edge of the cylindrical body 2 and the joining margin 4a of the frame are curled inwardly as shown in FIG. A peripheral edge of a rectangular back plate 7 having locking grooves 6, 6 formed at left and right positions around the edge and having rounded corners so that the outer peripheral edge fits the inner peripheral surface of the cylinder body 2. As shown in FIG. 6, they are constructed by joining 8 by caulking. Reference numerals B and B denote inner wall plates attached to the left and right inner surfaces of the cylindrical body 2, which are made of synthetic resin, and have a plurality of horizontally extending parallel guide bars 9, protrusions 10, and protrusions 11 on their inner surfaces. but,
Further, a plurality of reinforcing bars 12 are integrally molded in the longitudinal direction on the outer surface, and the front edges of the inner wall plates B, B are placed between the horizontal piece of the frame 4 and the inner surface of the cylinder 2. ,
Moreover, by inserting the rear edge between the locking groove 6 of the back plate 7 and the inner surface of the cylinder body 2, it is attached to the left and right inner surfaces of the outer casing A, respectively. Reference numeral C designates a drawer having a handle portion on the front wall surface, which is fitted between the inner wall plates B, B, received by the guide bar 9, and is provided in the outer casing A so that it can be drawn out. Note that 13 is a tray mat, and 14 is a cushion leg.

When in use, small items are stored in the drawer C, and the tray portion 3 is used to temporarily place small items taken out from the drawer.

Effects of the invention As described above, according to the present application, the cylinder body, frame body, and back plate constituting the outer casing made of metal plates are constructed as separate bodies, and these are joined by a process such as caulking, thereby omitting the welding process. Because of this structure, it is possible to use a metal plate with excellent decorative printing etc. for the cylinder body, making it possible to provide a product that is rich in taste. Even if the corners of the body are rounded, the inner periphery of the frame can be formed into a rectangular shape with right-angled corners, regardless of the shape, so the drawer can be tightly fitted to the front opening of the outer casing. In addition to being easy to join the cylindrical body and frame, it is convenient to manufacture, and has sufficient mechanical strength, and the frame and back plate are obtained by metal pressing. This has the advantage that there is no risk of bonding marks appearing on the front corner portion of the outer casing as in the conventional case, and a product with good overall appearance and extremely high commercial value can be provided.
