Abstract

<P>PROBLEM TO BE SOLVED: To provide a housing for storing an apparatus which can realize reduction in weight by means of strong housing body and a door, and thin plate material, has a small amount of projection to an inside of the housing body of a junction and hardly generates rust since a cutting surface is not exposed, thus improving safety by preventing an operator from getting hurt. <P>SOLUTION: The housing 1 for storing an apparatus consists of a housing body 2 and a door 3. The housing body 2 is formed by joining a upper plate 7 and a bottom plate 8 to a main body 6, wherein a rear plate 4 and both right and left side surface plates 5, 5 are integrally formed. The junctions are welded by performing hemming bending only for an end edge of one plate material, and an end edge except for the junction is subjected to hemming bending to an inside. All the end edges of the door 3 are also subjected to hemming bending to an inside. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a device storage box that stores electrical devices, communication devices, and the like.

  2. Description of the Related Art A device storage box for storing conventional electrical equipment, communication equipment, and the like is composed of a box body having an open front surface and a door body that closes the front opening of the box body so as to be freely opened and closed. . The box body is formed by joining a plurality of metal plate materials, and as a joining structure, for example, as shown in Patent Document 1, a self-letter shaped receiving portion is formed on the edge of one plate material, and the other An insertion piece having an abutting step surface corresponding to the step surface of the receiving portion is formed on the edge portion of the plate member, and when the insertion piece is inserted into the receiving portion by hemming the tips of both of them, By engaging the tip, it joins without welding. Moreover, the opening part and door body of the box main body were exposed with the edge part cut | disconnected.

Utility Model Registration No. 2517382

  As described above, the conventional box for storing electrical equipment has a disadvantage that the amount of protrusion to the inside of the box body is large because the joint portion is formed with a stepped surface for butting. Further, in order to ensure strength so that the box body and the door body are not deformed by their own weight, the plate thickness has to be increased. Therefore, there are disadvantages that the material cost is increased and the weight is increased. In addition, since the cut surface is exposed at the edge of the opening of the box body and the door body, rust is likely to occur and there is a risk of injury.

  The present invention relates to a device storage box composed of a box body formed in a shape in which a plurality of plate members are joined and the front surface is opened, and a door body that freely closes the front opening of the box body. The joints between the plate members of the box body are joined by hemming and bending only the edge portion of the plate material on one side, and all the edge portions of the box body and the door body except for the joint portion are hemmed and bent inward. It is characterized by that.

  According to the present invention, the strength can be secured even if the plate thickness of the box body and the door body is reduced, and by reducing the plate thickness, the weight of the box body and the door body can be reduced and the material cost can be reduced. In addition, the amount of protrusion of the joint portion to the inside of the box body is small, and further, since the cut surface is not exposed, rust is unlikely to occur, and injuries can be prevented and safety is improved.

  In a box body for equipment storage composed of a box body formed by joining a plurality of plate members and having a front surface opened, and a door body for closing the front opening of the box body so as to be openable and closable. The joining portions of the plate members are joined by hemming and bending only the edge portion of the plate material on one side, and all the edge portions of the box body and the door body except the joining portion are hemmed and bent inward.

  A first embodiment of a device storage box according to the present invention will be described with reference to the accompanying drawings of FIGS.

  The device storage box 1 is formed of a metal plate material, and includes a box body 2 having an open front surface, and a door body 3 that closes the front opening of the box body 2 so as to be freely opened and closed. The box body 2 is formed by joining a top plate 7 and a bottom plate 8 to a body 6 in which a back plate 4 and left and right side plates 5 and 5 are integrally formed.

  The main body 6 is formed by bending the left and right sides of a rectangular plate material forming the back plate 4 to the front side to form left and right side plates 5, 5, and the front edge is bent vertically inward. Further, the top plate 7 and the bottom plate 8 are formed by bending four sides of the rectangular plate material inwardly, and two adjacent sides are welded. Then, the front plate 7, the bottom plate 8, and the front side edge of the main body 6 are hemmed inward, and the hemming portion 9 is bent twice in the outer direction to form a draining piece 10.

  In order to join the members formed in this way, the joint between the top plate 7 and the upper end of the main body 6 and the joint between the lower end of the main body 6 and the bottom plate 8 are the lower ends of the top plate 7 and the main body 6. Hemming bends the three sides excluding the front side of the part inward, and the tips of the hemming parts 11 and 12 are further folded back into a hairpin shape to form receiving parts 13 and 14 into which the other plate material is inserted. The upper end portion forms a step bent portion 15 corresponding to the thickness of the hemming portion 11 of the upper surface plate 7. And the joining part of the upper end part of the upper surface board 7 and the main body 6 inserts the insertion piece 16 of the front end side from the step bending part 15 in the receiving part 13, makes the step bending part 15 contact | abut to the hemming part 11, and is welded, The joint between the lower end portion of the main body 6 and the bottom plate 8 is welded by inserting the insertion piece 17 at the tip into the receiving portion 14. Then, the box body 2 is formed by welding edge portions of adjacent draining pieces 10 together. As described above, only the edge portion of the plate member on one side is hemmed and bent, so that the joining portion can reduce the amount of protrusion to the inside of the box body 2.

  The door body 3 is formed by hemming and bending four sides of a rectangular plate material, bending the hemming portion 18 vertically to the back side, and welding two adjacent sides, and can be opened and closed on the front surface of the box body 2. Butterfly.

  As described above, since the edge portions of the plate members constituting the respective portions are hemmed and bent, the strength is improved, and hence the plate thickness can be reduced, so that the weight of the box body and the door body can be reduced and the material cost can be reduced. Further, since the cut surface is not exposed by hemming bending, rust is hardly generated, and injury can be prevented and safety is improved.

  Note that there is no limitation on the bonding structure as long as the bonding portion is bonded by hemming only the plate material on one side, and there is no limitation on the shape and configuration of the box body and the door body. Can be implemented.

The apparatus storage box concerning this invention is shown, (a) is a front view, (b) is a top view, (c) is a right view. It is the side view which decomposed | disassembled the apparatus storage box concerning this invention. It is the sectional view on the AA line of FIG. It is the B section enlarged view of FIG.
