Description

[Technical field]

[0001] The present invention relates to a cable support device that can be fixed to a plurality of cable racks with different parent girder dimensions with a simple operation. [Background technology]

[0002] In wiring work, when adding more cables after the cables have been laid inside the installed cable rack, it may not be possible to lay the cables inside the rack. For example, when adding a low-voltage cable, a separator is required, so the cable cannot be laid inside the rack after the cables have been laid. In this case, the use of hanging bolts instead of cable racks is considered.

[0003] The applicant has previously proposed a cable support that is fixed to a hanging bolt (Patent Document 1). This cable support is configured to fix a cable support having a substantially J-shaped side to a hanging bolt. That is, a pair of clamps are provided to clamp both sides of the hanging bolt, and the upper end of the cable support is fixed to each clamp with a screw.

[0004] The applicant has also proposed a pipe support fixed to a cable rack (Patent Document 2). This pipe support is configured to support piping on the parent girder of the cable rack. According to this configuration, the pipe support is fixed to the parent girder with an upper metal fitting that engages with the inside of the horizontal edge of the parent girder and a lower metal fitting that engages from the outer surface to the underside of the parent girder, and the fixed upper metal fitting supports the piping.

[0005] [Patent Document 1] Japanese Patent Application Publication No. 10-185002 [Patent Document 2] JP 2001-136629 A Summary of the Invention [Problem to be solved by the invention]

[0006] When installing additional cables using the cable support described in Patent Document 1, the suspension pitch of the suspension bolts is wide, which causes the cables to sag, resulting in an unsightly appearance.

[0007] Therefore, in order to fix a cable support to a cable rack instead of using a hanging bolt, a structure is required in which the cable support is fixed to the parent girder using an upper fitting that engages with the upper end of the parent girder and a lower fitting that engages with the bottom from the outer surface of the parent girder, as in the configuration described in Patent Document 2.

[0008] However, since multiple types of cable racks with different parent girder dimensions are usually used, forming the upper fittings and lower fittings to fit one type creates the inconvenience that they cannot be used with other types with different parent girder dimensions.

[0009] Moreover, conventional cable supports and pipe supports require multiple components such as upper and lower fittings to be fixed with screws, etc., which means that the installation work required a lot of work when fixing the supports. Also, manufacturing supports made of multiple components to suit each type of cable rack raises the issue of manufacturing costs.

[0020] The cable support of the present invention is a cable support having a lip portion such as a cable rack or a cable duct. groove shape It supports cables P and PF pipes along the outer surface of the main body 2 of the steel trough 1, and is formed integrally with a support 10 and a fixed body 20. The support 10 is a part that supports the cables P, etc., and is disposed on the outer surface of the side plate 2B of the main body 2 (see Figure 7).

[0021] The support 10 includes a connecting portion 11 that hangs down along the outer surface of the side plate 2B, and a support portion 12 that is bent from the tip of the connecting portion 11 and supports the cable P (see FIG. 1 ). It comes into surface contact with the outer surface of the main body 2 (see Figure 4 (c)). A cover portion 13 is formed from the connecting portion 11 to the support portion 12 (see FIG. 3). This cover portion 13 protects the cable P that is engaged with the support 10, and is formed of a vinyl coating or the like.

[0022] Furthermore, the connecting portion 11 comes into contact with the side plate 2B of the main body 2 to prevent the support 10 from shaking. Furthermore, the cover portion 13 comes into contact with the side plate 2B of the main body 2 to also prevent shaking.

[0023] The fixed body 20 is groove shapeIt is a band-shaped elastic part that is fixed to the main body 2 of the steel gutter 1. The fixed body 20 is configured to include a contact piece 21, an elastic part 22, a bent piece 23, and a locking projection 24 (see FIG. 1).

[0024] The abutment piece 21 is a portion that abuts against the upper surface of the lip portion 2A of the main body 2. The illustrated abutment piece 21 abuts against the upper surface of the lip portion 2A of the cable rack, but the abutment piece 21 may be abutted against the upper surface of a cable duct or the like having a similar lip portion. groove shape It can also come into contact with the steel gutter 1. The elastic portion 22 is a portion that extends in an arc shape from the tip of the contact piece 21 and wraps around the inner surface of the lip portion 2A (see FIG. 5).

[0025] The contact piece 21, the elastic portion 22, and the bending piece 23 are of different sizes. groove shape In order to be compatible with steel gutters 1, they are pre-formed to fit larger sized steel gutters 1, i.e., main bodies 2 with long lip portions 2A (see Figs. 5 and 6). When attached to main bodies 2 with short side plates 2B, cables P can also be supported on the underside of the main body 2.

[0026] On the other hand, the bent piece 23 is bent obliquely downward from the tip of the elastic portion 22. Surface shape It is a part the law of nature (See Figure 2) , which comes into surface contact with the inner surface of the main body 2 (see FIG. 4(c)). The tip of this bent piece 23 is formed so as to come into contact with the inner surface of the side plate 2B of the main body 2 when the fixing body 20 is fixed to the lip portion 2A (see FIG. 4(c)). Then, the bent piece 23 engages with and braces the inner surface of the main body 2, so that the connecting portion 11 comes into contact with the side plate 2B of the main body 2, and the connecting portion 11 comes into contact with the side plate 2B of the main body 2.

[0027] The locking projection 24 is an extension formed from the rear end of the bent piece 23, and is a projection that locks onto the inside of the lip portion 2A of the main body 2 (see Figs. 5 and 6). That is, when the fixing body 20 is attached to the lip portion 2A of the main body 2, the tip of the locking projection 24 is configured to abut against the inner surface of the lip portion 2A (see Fig. 4(c)).

[0028] The illustrated locking projection 24 is formed via a pair of left and right cutouts 24A formed obliquely outward from the bent portion of the elastic part 22 and the bent piece 23 toward the bent piece 23 (see FIG. 2). When the bent piece 23 is bent downward, the locking projection 24 is formed to rise obliquely upward from the cutouts 24A.

[0029] At this time, the upper end of the locking projection 24 is formed so as to protrude upward from the abutting piece 21 through a notch 21A formed in advance in the abutting piece 21 (see Figs. 1 and 2). This makes it possible to further strengthen the clamping force applied to the lip portion 2A of the main body 2 by the abutting piece 21 and the locking projection 24 (see Figs. 5 and 6).

[0030] In addition, by forming the support 10 and the fixed body 20 integrally with a strip plate, it is possible to eliminate the gap between the support 10 and the main body 2. groove shape A cover can be attached (not shown) to cover the opening of the steel gutter 1. Note that even without the bent piece 23, the cover can be attached by pushing the connecting part 11 toward the main body 2 and abutting it against the side plate 2B.

[0031] The support of the present invention can be attached to the main body 2 by a simple operation (see Figs. 4(a) to (c)). That is, as shown in (a), the support 10 is placed on the upper surface of the lip portion 2A of the main body 2, and the fixing body 20 is placed on the underside of the lip portion 2A. Next, as shown in (b), the support 10 is rotated toward the side plate 2B of the main body 2, and as shown in (c), the fixing body 20 is attached in a state in which the locking projection 24 is locked to the underside of the lip portion 2A of the main body 2.

[0032] Thereafter, the bent piece 23 comes into contact with and engages with the inner surface of the side plate 2B of the main body 2 (see Figs. 5 and 6). As a result, the locking projection 24 and the bent piece 23 simultaneously lock with the lip portion 2A and the side plate 2B of the main body 2, providing an extremely strong locking force.

[0033] The configurations of the present invention are not limited to the illustrated examples, and design changes are free to the extent that they do not change the gist of the present invention. For example, the material of the support bracket can be made of synthetic resin material in addition to metal material. [Explanation of symbols]
