Abstract

PROBLEM TO BE SOLVED: To install a cabinet simply and in a short time by eliminating a scribing step for a mounting hole.SOLUTION: A cabinet 1 includes a box body 2 in which an electric apparatus or the like is housed; and a front door 3. This cabinet is mounted on a wall surface by bolts passing through mounting holes 5 formed on a rear surface 4 of the box body 2. The cabinet 1 at the time of factory shipment does not include the mounting holes 5 in the box body 2. Instead, marked holes 7 showing positions of the mounting holes 5 to be processed are formed on the rear surface 4 of the box body 2. The marked holes 7 are formed by the diameter which is smaller than the mounting holes 5 and arranged at four corners of the rear surface 4 at an equivalent pitch P.

Description

  The present invention relates to a cabinet that is attached to an installation location by an attachment member that passes through an attachment hole, a method of manufacturing the cabinet, and a method of attaching the cabinet to the installation location.

  Conventionally, a cabinet 51 as shown in FIG. 7 is known. The cabinet 51 includes a sheet metal box 52 and a front door (not shown). Attachment holes 53 are formed at the four corners of the box 52, and the box 52 is attached to the wall surface W with bolts 54 that pass through the attachment holes 53. Patent Document 1 describes a cabinet 51 configured to detachably assemble a substrate 55 inside a box body 52 and to mount various electrical devices 56 on the substrate 55.

  By the way, in this kind of cabinet 51, since the attachment position of the box 52 is easy to change according to an installation place, the attachment hole 53 may be processed in the place different from the manufacturing factory of the cabinet 51, or on-site adjustment. In such a case, usually, as shown in FIG. 8, a ruled line 57 is drawn on the mounting surface of the box 52 in accordance with the mounting position of the installation place, and the intersection of the ruled line 57 is drilled with a drill D to attach the mounting hole 53. Is processed. For this reason, according to the conventional cabinet 51, a ruled writing process is required for processing the mounting hole 53, and there is a problem that installation work takes time and effort.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a cabinet that can omit the marking process of the mounting holes, and a method for manufacturing and mounting the cabinet.

In order to solve the above problems, the present invention provides the following means.
(1) It is provided with a sheet metal box attached to an installation place by an attachment member that passes through the attachment hole, and a plurality of mark portions that selectively indicate a processing position of the attachment hole are formed on the box. cabinet.

(2) The cabinet according to (1) above, wherein the mark portion includes a mark hole having a diameter smaller than that of the mounting hole, and the plurality of mark holes are formed at an equal pitch on the mounting surface of the box.

(3) In manufacturing the cabinet described in 1 or 2 above, a metal plate is cut into a required shape by a laser processing machine, a plurality of mark portions are formed on the metal plate, and the metal on which the mark portions are formed And a step of assembling the box by bending the plate.

(4) When attaching the cabinet manufactured by the method described in 3 above to the installation location, drilling the mark portion corresponding to the installation location of the installation location with a drill and machining the installation hole; And a step of attaching the box body to the installation place by the attached attachment member.

  According to the cabinet of the present invention, since the plurality of mark portions are formed in advance in the box, the mark portion corresponding to the mounting position can be selected, and the mounting hole can be processed according to the mark portion. Accordingly, there is an effect that the ruled line process is omitted and the cabinet can be installed easily and in a short time.

It is a front side perspective view of the cabinet which shows one Embodiment of this invention. It is a back side perspective view of the cabinet of FIG. It is process drawing which shows the procedure which forms a mark hole in the back part of a box. It is process drawing which shows the procedure which processes an attachment hole according to a mark hole. It is the box body in which the mark hole was formed in the bottom face part, and its installation form figure. It is the box body in which the mark hole was formed in the side part, and its installation form figure. It is a front view which shows the box of the conventional cabinet. It is process drawing which shows the procedure which processes a mounting hole in the box of FIG.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. A cabinet 1 shown in FIG. 1 includes a box 2 for storing electrical equipment and the like, and a front door 3. Mounting holes 5 are formed at the four corners of the back surface portion 4 of the box 2, and the cabinet 1 is attached to the wall surface W of the installation place by bolts 6 that pass through the mounting holes 5.

  The number of mounting holes 5 is not limited to four, and may be more or less. Moreover, as a mounting member of the cabinet 1, in addition to the bolt 6, an appropriate member such as a screw or a hook can be used.

  As shown in FIG. 2, the cabinet 1 at the time of factory shipment does not have the mounting holes 5 (shown by phantom lines) formed in the box 2. Instead, a mark hole 7 indicating the machining position of the mounting hole 5 is formed in the back surface portion 4 which is the mounting surface of the box 2. The mark holes 7 are formed with a smaller diameter (for example, about 1 mm) than the mounting holes 5, and a plurality of the mark holes 7 are arranged at equal pitches P in the vertical and horizontal directions at the four corners of the back surface portion 4.

  The mark hole 7 may be a bottomless hole that penetrates the back surface portion 4 or may be a bottomed hole that does not penetrate the back surface portion 4. Further, in place of the mark hole 7, mark portions such as a dent, a dent, and a notch may be formed on the mounting surface of the box body 2.

  In manufacturing the box 2, as shown in FIG. 3, first, using a laser processing machine, the metal plate 8 is cut into a required shape by the laser head LH, and a predetermined portion of the metal plate 8 is formed by the same head LH. A mark hole 7 is formed. Next, the metal plate 8 on which the mark portion 7 is formed is bent, the joint portion is welded, and the box body 2 is assembled. Then, the door 3 is assembled | attached to the front surface of the box 2, and the cabinet 1 is completed.

  When attaching the cabinet 1 to an installation location, first, a box 2 (see FIG. 2) in which the attachment holes 5 are not processed is prepared. Next, as shown in FIG. 4, a hole 7 corresponding to the mounting position is selected from among the plurality of mark holes 7, and the mark hole 7 is drilled with a drill D to process the mounting hole 5. And the box 2 is attached to the wall surface W with the volt | bolt 6 which let the attachment hole 5 pass (refer FIG. 1). In this way, it is possible to omit the ruled work and install the cabinet 1 easily and in a short time.

  In addition, this invention is not limited to the said embodiment, For example, as shown to Fig.5 (a), the mark hole 7 is formed in the bottom face part 9 of the box 2, and as shown in FIG.5 (b), The cabinet 1 can also be installed on the horizontal plane H. Further, as shown in FIG. 6A, a mark hole 7 is formed in the side surface portion 10 of the box 2, and the cabinet 1 is installed along the vertical plane V as shown in FIG. 6B. You can also. In addition, the shape and configuration of each part can be changed as appropriate without departing from the spirit of the present invention.
