[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cable rack.

[0002]

[Prior art]

 Cable racks are used as wiring equipment in cable wiring work in factories, buildings, warehouses, common ditch, etc. The cable rack includes a pair of extension members and a plurality of girder members disposed between the pair of extension members to extend the pair of extension members in parallel at regular intervals. Bull racks are installed at desired locations inside or outside the building. The cable rack is provided with a cable such as an electric cable so as to be orthogonal to the girder material of the cable, and the cable is a girder member such as a band. It is supposed to be wrapped with the timber and tied (usually in a plowed condition).

By the way, the cable rack as described above is generally constructed by welding both ends of each girder member to a pair of extension members by welding or by fixing with screws. The extension member and each girder member are immovable.

[0004]

[Problems to be solved by the device]

 However, the cable rack is a relatively large assembly (width 100 to 1500 mm, extension length is about 3 m), and it is not easy to transport and carry such a large cable rack before use. .. When stocking such cable racks, a large stocking place must be prepared. The present invention has been made in view of the above circumstances, and an object thereof is to provide a cable rack whose size before use can be made as small as possible.

[0005]

In order to achieve the above object, in the present invention, a pair of extending members and a pair of extending members are arranged in parallel with each other at a constant interval. In a cable rack made up of a plurality of girder members extended to each other, both ends of each girder member are rotatably connected to the pair of elongate members. With the above-mentioned structure, when a pair of extension members are fixed to the installation place during use, each girder member is immovable, and the normal function of the cable rack can be achieved. Before use, since both ends of each girder member are rotatably connected to the pair of extension members, the pair of extension members are folded so that the interval between the pair of extension members is narrowed. It will be possible. Therefore, before using the cable rack, the size of the cable rack can be reduced as much as possible.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, 3 is a cable rack according to the first embodiment, and in this embodiment, the cable rack 3 is a suspension bolt 2 and a rack fixing bracket 5, which are fixed to a ceiling or an upper structure. It is fixed to the space by 6 by being extended in the horizontal direction.

As shown in FIG. 1, the cable rack 3 includes a pair of linear members 7 a and 7 b as extending members and a plurality of girder members 8.

The pair of linear members 7 a and 7 b extend in parallel in the horizontal direction at regular intervals, and both linear members 7 a and 7 b are installed in the space by the hanging bolt 2.

The plurality of girder members 8 are arranged between the pair of linear members 7a and 7b at predetermined intervals in the extending direction of the pair of linear members 7a and 7b. As shown in FIGS. 2 to 4, a channel material is used for each girder member 8, one end of which is connected to the straight member 7a via a hinge 16a, and the other end thereof includes a hinge 16b. It is connected to the straight member 7b through. One end of the hinge 16a is fixed to the side inner surface 10a of the linear member 7a with a screw 11, and the other end of the hinge 16a is welded to one side surface of the beam member 8 in the width direction (see FIG. 4). , 12 indicates spot welding points), and they are fixed by caulking or the like. On the other hand, one end of the hinge 16b is fixed to the side inner surface 10b of the straight member 7b with a screw 11, and the other end of the hinge 16b is welded to the other widthwise side face of the beam member 8 in the same manner as above. It is fixed by.

Therefore, before such a cable rack 3 is used, the linear members 7a and 7b are moved close to each other by the action of the hinge 16a (16b) as shown in phantom lines in FIG. 2 and FIG. You will be able to fold it. For example, for a cable rack 3 having an extension length of 3000 mm and a width of 600 mm in a regular use shape, the extension length is about 3600 mm, but the width can be about 150 mm. For this reason, the cable rack 3 can be easily transported and transported because the cable rack 3 can be folded and reduced in size. In particular, at the time of shipping, it is preferable to tie the folded cable rack 3 with a band or the like (indicated by an imaginary line in FIG. 5) 13 as shown in FIG. At the same time, since it is possible to fold the cable rack 3, it is not necessary to prepare a large stock location for the cable rack 3.

On the other hand, when the cable rack 3 is used, if the beam member 8 is changed from the state of the phantom line in FIG. 2 to the state of the solid line with respect to the linear members 7a and (7b), the cable rack 3 becomes , It becomes a regular use shape. In this case, since both end surfaces of the girder member 8 contact the side inner surface 10a (10b) of the linear member 7a (7b) and the girder member 8 does not rotate after the contact, the cable rack 3 is While it is possible to immediately know whether or not the regular use shape has been obtained, it becomes easy to maintain the regular use shape.

After the cable rack 3 is formed into a regular use shape, each pair of linear members 7a and 7b are fixed by fixing fittings 5 and 6 as shown in FIG. It becomes immovable with respect to the materials 7a and (7b). Therefore, as shown in FIG. 1, the cable 14 can be fixed to the cable rack 3 using the auxiliary tool 9 and the band 15 as usual.

6 and 7 show a second embodiment. In the second embodiment, the same components as those in the previous embodiment are designated by the same reference numerals, and the description thereof will be omitted. The one side 7a of the pair of straight members 7a and 7b will be described as a representative example. In this second embodiment, as shown in FIG. 7, a bracket 17 having an L-shaped cross section is attached to the side inner surface 10a of the straight member 7a, and the mounting portion 17a of the bracket 17 is attached to the straight member 7a. It extends inward.

An end portion of the girder member 8 is rotatably supported by a mounting portion 17 a of the bracket 17 using a rivet 18. In order to avoid the interference between the end surface of the girder member 8 and the side inner surface 10a of the linear member 7a due to the rotation of the girder member 8, the girder member 8 has an end surface of the linear member 7a. The side portion inner surface 10a (in this embodiment, the bracket 17) is separated from the side portion by a constant distance L 1, and the end portion of the beam member 8 has an inclined portion functioning as a stopper at the time of folding, as shown in FIG. 19 are formed.

Further, as shown in FIG. 6, an arcuate guide hole 20 centering on the rivet 18 is formed in the girder material 8. Into the guide hole 20, a guide pin 21 that is planted in the mounting portion 17a of the bracket 17 is inserted, and the guide pin 21 and the inner end portion of one end of the guide hole 20 are brought into contact with each other so that a linear member is formed. Positioning of the regular use shape of the girder material 8 with respect to 7a is performed (see FIG. 6).

A torsion spring 22 is fitted and inserted in the rivet 18. One end of the torsion spring 22 is engaged with the girder member 8 and the other end is engaged with the guide pin 21, and the torsion spring 22 allows the girder member 8 to be aligned with the straight member 7a. It is supposed to be urged toward the usage shape position.

Therefore, in this cable rack 3, when it is folded, it must be folded against the urging force of the torsion spring 22, but the inclined portion 19 abuts the side inner surface 10a of the straight member 7a. The folded cable rack 3 can be easily returned to its normal use shape by the urging force of the torsion spring 22.

FIG. 8 shows a third embodiment. Also in this embodiment, the same components as those in the first and second embodiments are designated by the same reference numerals and the description thereof will be omitted. In the third embodiment, the girder member 8 is only rotatably supported by the mounting portion 17a of the bracket 17 using the rivet 18, but if the pair of straight members 7a and 7b are fixed, Since the beam member 8 is in an immovable state, the cable rack 3 can have a function as a normal cable rack and a folding function thereof with an extremely simple structure. In this embodiment, the inclined portions 19 are provided on both sides in the width direction of the end portion of the girder member 8.

Although the embodiments have been described above, the present invention includes the following. As a usage mode of the cable rack 3, not only the cable rack 3 is disposed in the horizontal direction but also in any direction such as the vertical direction. In order to exert the same function as the guide pin 21 and the guide hole 20 of the second embodiment, the mounting portion 17a of the bracket 17 is bulged to form a protruding portion, and the beam member 8 is recessed to form an arc shape. Groove, and fit the protruding part into the arc-shaped groove.
