[0016] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0017] FIG. 1 is a diagram showing a schematic diagram of the internal structure of a cubicle housing 100 having a cubicle housing frame 1 therein according to an embodiment of the present invention.

[0018] The cubicle housing 100 has a cubicle housing frame 1 inside, and various devices such as transformers, circuit breakers, switches, protective devices, and meters for monitoring voltage, current, and power are fixed to this cubicle housing frame 1.

[0019] The cubicle housing frame 1 comprises a plurality of support columns 10 and a plurality of horizontal members 20. The support columns 10 are erected vertically inside the cubicle housing 100, and the horizontal member 20 is a long member that connects at least two support columns 10, 10. The support columns 10 and horizontal members 20 are made of metal. The cubicle housing frame 1 is a structure formed by connecting the horizontal members 20 so as to span the plurality of support columns 10.

[0020] FIG. 2 is a perspective view showing an example of a cubicle housing frame 1 according to an embodiment of the present invention.

[0021] The support 10 is a columnar member having a U-shaped end face, formed by opening one flat portion of a long rectangular tube. The three rectangular flat plate portions 10a constituting the support 10 have a plurality of through holes 10b formed in the center at equal intervals along the longitudinal direction. The through holes 10b are square holes, with two sides of the square parallel to the longitudinal direction of the support 10 and the other two sides perpendicular to the longitudinal direction of the support 10. Furthermore, screw holes 10c for screw fastening are formed in the flat plate portions 10a. The screw holes 10c are formed between two adjacent through holes 10b. According to this embodiment, screw holes 10c are formed between the second and third through holes 10b from the top, between the fourth and fifth through holes 10b, and so on, with two through holes 10b spaced between them.

[0022] The horizontal member 20 has a long, rectangular flat plate surface, and is attached to the support 10 with the end of the flat plate surface of the horizontal member 20 abutting against the flat surface of the support 10. The horizontal member 20 has the function of reinforcing the cubicle housing frame 1 and the function of supporting various devices directly or indirectly via metal fittings, etc.

[0023] The horizontal members 20 are broadly divided into three types: horizontal members 21 that are fixed to the support 10 by bolts passed through the through holes 10b; horizontal members 22 that are fixed to the support 10 by screws passed through the screw holes 10c; and horizontal members 23 that have engaging portions 23c that engage with the edge of the through holes 10b and are attached to the support 10 by inserting the engaging portions 23c into the through holes 10b.

[0024] The cubicle housing frame 1 further includes a bottom plate 30. The bottom plate 30 is a U-shaped member having a rectangular flat plate portion 30a and wall surface portions 30b formed by bending both ends of the flat plate portion 30a at right angles.

[0025] According to this embodiment, a right-angled triangular extension 10d is formed at the bottom of one of two opposing flat plate portions 10a, 10a of the support 10. The support 10 is fixed to the bottom plate 30 by screwing the extension 10d in a state in which the outer surface of the extension 10d abuts against the inner surface of the wall portion 30b. In this way, the two support columns 10, 10 are erected on the bottom plate 30.

[0026] In this way, the cubicle housing frame 1 is assembled by installing two support pillars 10, 10 upright on the bottom plate 30, fixing both ends of the horizontal member 21 to the upper ends of the two support pillars 10, 10, and further attaching horizontal members 22, 23 to the two support pillars 10, 10. The cubicle housing frame 1 is placed inside the cubicle housing 100.

[0027] Fig. 3 shows an example of the horizontal member 23, with Fig. 3(a) being a plan view, Fig. 3(b) being a front view, and Fig. 3(c) being a side view. Fig. 4 is an enlarged view of part A in Fig. 3(c).

[0028] The horizontal member 23 has a rectangular flat surface portion 23a, rectangular wall surface portions 23b extending perpendicularly to the plane of the flat surface portion 23a from the centers of the two long sides of the flat surface portion 23a, and engaging portions 23c extending from both ends of the two short sides of the flat surface portion 23a. That is, the horizontal member 23 has two wall surface portions 23b and four engaging portions 23c.

[0029] The long side of the flat surface portion 23a is set to the distance between the central axes of the two pillars 10, 10. The short side of the flat surface portion 23a is set to be slightly longer than the length from the upper end of a given through-hole 10b in one pillar 10 to the lower end of the second lower through-hole 10b. The two wall surface portions 23b, 23b of the wall surface portion 23b face each other.

[0030] The four engaging portions 23c extend in the opposite direction to the wall surface portions 23b, 23b. The tip of each engaging portion 23c is formed in a hook shape, and the tip of this hook-shaped portion is formed in an arc shape, and the maximum width of the hook-shaped portion (the width indicated by the symbol B in FIG. 4) is set to a width that allows it to be inserted into the through-hole 10b. In addition, the gap between the tip of this hook-shaped portion and the short side of the flat portion 23a (the gap indicated by the symbol C in FIG. 4) is set to be slightly larger than the thickness of the support 10.

[0031] The distance between the two engaging portions 23c, 23c formed on each short side of the flat portion 23a is set to the length between the center of a predetermined through hole 10b in one support 10 and the center of the through hole 10b two holes below this through hole 10b. Therefore, the two engaging portions 23c, 23c extending from both short sides of the flat portion 23a can be made to face the two predetermined through holes 10b, 10b formed in the two supports 10, 10, respectively.

[0032] Then, the four engaging portions 23c are inserted into the four through-holes 10b, the flat portion 23a is moved slightly downward, and the hook-shaped portions are engaged with the lower edges of the through-holes 10b, thereby attaching the horizontal member 23 to the two posts 10, 10 as shown in Fig. 1. Conversely, when removing the horizontal member 23, the flat portion 23a is moved slightly upward to release the engagement between the hook-shaped portions and the lower edges of the through-holes 10b, and the engaging portions 23c are pulled out of the through-holes 10b, thereby removing the horizontal member 23.

[0033] 5A to 5C are diagrams showing another example of the horizontal member 23, in which FIG. 5A is a plan view, FIG. 5B is a front view, and FIG. 5C is a side view.

[0034] 5 includes a main body 23d and engagement portions 23e and 23f. Main body 23d is a long member that is U-shaped in side view and has a rectangular planar portion 25 and rectangular, flat-plate-like wall portions 26 and 27 that extend perpendicularly from the two long sides of planar portion 25.

[0035] Engagement portion 23e is formed in a so-called L-shape, extending perpendicularly to flat surface portion 25 from both sides of the tip of wall surface portion 26 and further extending upward parallel to flat surface portion 25. Engagement portion 23f extends linearly from both sides of the tip of wall surface portion 27 in a direction perpendicular to flat surface portion 25. The width of engagement portion 23e and engagement portion 23f is set to be slightly shorter than one side of square through-hole 10b and to an extent that it can be inserted into through-hole 10b. The tip of engagement portion 23e is formed in an arc shape.

[0036] The interval between the wall surface portions 26, 27 is set to the length between the centers of two adjacent through holes 10b, 10b formed in one support 10. Therefore, the engaging portions 23e, 23f extending from both longitudinal ends of the main body portion 23d can be made to face the two predetermined adjacent through holes 10b, 10b in the two supports 10, 10.

[0037] Then, the engaging portion 23e is inserted into the upper through-hole 10b, and while rotating the main body portion 23d, the engaging portion 23f is inserted into the lower through-hole 10b, and the main body portion 23d is moved slightly downward until the engaging portion 23f abuts against the lower edge of the through-hole 10b. This allows the horizontal member 23 to be attached to the two posts 10, 10, as shown in FIG. 6. Conversely, to remove the horizontal member 23, the main body portion 23d is moved slightly upward to separate the engaging portion 23f from the lower edge of the through-hole 10b, and the main body portion 23d is rotated toward the front to remove the engaging portion 23f from the lower through-hole 10b, and further, the engaging portion 23e is removed from the upper through-hole 10b, thereby removing the horizontal member 23 from the two posts 10, 10.

[0038] [Action and effect] According to the present embodiment described above, the following advantageous effects are achieved. According to this embodiment, the horizontal member 23 can be attached to the support 10 by inserting the engaging portion 23c or the engaging portions 23e, 23f of the horizontal member 23 into the through hole 10b and engaging them with the edge of the through hole 10b. As described above, according to this embodiment, since no screws or bolts are used, it is possible to reduce the number of screws used to assemble the cubicle housing frame 1, and the cost of screws and bolts can be reduced.

[0039] Furthermore, the work of fixing the horizontal member 23 to the support 10 with screws or bolts, such as screwing or bolting, is reduced, and the horizontal member 23 can be attached to the support 10 by the simple procedure of inserting the engaging portion 23c or the engaging portions 23e and 23f into the through-hole 10b and engaging them with the edge of the through-hole 10b. This makes it possible to significantly improve the workability when attaching the horizontal member 23.

[0040] Although the embodiments of the present invention have been described above, the embodiments of the present invention are not limited to the above-described embodiments. For example, the shape of the parts of the horizontal member 23 other than the engaging portion 23c or the engaging portions 23e, 23f can be set as appropriate. Furthermore, the arrangement of the engaging portions 23c or the engaging portions 23e, 23f on the horizontal member 23 can also be set as appropriate, as long as the multiple engaging portions 23c or the engaging portions 23e, 23f on the horizontal member 23 can be simultaneously inserted into either of the through holes 10b formed in the two supports 10.
