Description

[Technical Field]

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

[0002] During wiring work, if you want to add more cables after running them inside the installed cable rack, it may not be possible to run the cables inside the rack. For example, if you want to add a low-voltage cable, a separator is required, so you cannot run the cables inside the rack after the cables have already been run. In this case, it is possible to use hanging bolts instead of cable racks.

[0003] The applicant has previously proposed a cable support that is fixed to a suspension bolt (Patent Document 1). This cable support is configured to be fixed to a suspension bolt with a substantially J-shaped side. That is, a pair of clamps is provided to clamp both sides of the suspension 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 that is fixed to a cable rack (Patent Document 2). This pipe support is configured to support piping on the main girder of the cable rack. According to this configuration, the pipe support is fixed to the main girder with an upper fitting that engages with the inside of the horizontal edge of the main girder and a lower fitting that engages from the outer surface of the main girder to the underside, and the piping is supported by the fixed upper fitting.

[0006] When installing additional cables using the cable support described in Patent Document 1, the hanging pitch of the hanging bolts is wide, which causes the cables to sag and results in a poor appearance.

[0007] Therefore, in order to fix the cable support to the 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 outer surface of the parent girder from the bottom, as in the configuration described in Patent Document 2.

[0008] However, because cable racks are typically made of multiple types with different girder dimensions, forming upper and lower fittings to fit one type creates the inconvenience of making them incompatible with other types with different girder dimensions.

[0009] Furthermore, conventional cable supports and pipe supports require multiple components, such as upper and lower fittings, to be fastened together with screws, etc., which means that the installation process for fastening the supports is also labor-intensive. Also, manufacturing supports made up of multiple components to suit each type of cable rack poses a manufacturing cost problem.

[0010] The present invention was created to solve the above-mentioned problems, and aims to provide a cable support that can be fixed to any of a variety of cable rack types and that is extremely easy to fix. [Means for solving the problem]

[0020] The cable support of the present invention is a cable rack or cable duct having a lip. 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 body 10 and a fixed body 20. The support body 10 is the part that supports the cables P, etc., and is arranged 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 body 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 strip-shaped elastic part that is fixed to the main body 2 of the steel gutter 1. The fixed body 20 is configured with a contact piece 21, an elastic part 22, a bent piece 23, and a locking protrusion 24 (see Figure 1).

[0024] The contact piece 21 is a portion that contacts the upper surface of the lip portion 2A of the main body 2. The contact piece 21 shown in the figure contacts the upper surface of the lip portion 2A of the cable rack, but it may also contact the upper surface of a cable duct or the like that has 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 able to accommodate steel troughs 1, they are pre-formed to fit larger sized steel troughs 1, i.e., main bodies 2 with long lip portions 2A (see Figures 5 and 6). Also, when attached to main bodies 2 with short side plates 2B, cables P can 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) , and comes into surface contact with the inner surface of the main body 2 (see Figure 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 is aligned with the side plate 2B of the main body 2.

[0027] The locking projection 24 is a protrusion formed by extending from the rear end of the bent piece 23, and is engaged with 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 comes into contact with the inside surface of the lip portion 2A (see Fig. 4(c)).

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

[0029] At this time, the upper end of the locking projection 24 is formed so as to protrude upward from the contact piece 21 through a notch 21A formed in advance in the contact 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, which is clamped between the contact piece 21 and the locking projection 24 (see FIGS. 5 and 6).

[0030] Furthermore, 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, so that even after the support 10 is attached, groove shape A cover (not shown) can be attached 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 where the locking protrusions 24 are locked onto the underside of the lip portion 2A of the main body 2.

[0032] Thereafter, the bent piece 23 comes into contact with and locks against 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 various configurations of the present invention are not limited to the examples shown in the drawings, and design changes are free to be made within the scope of the present invention. For example, the material of the support bracket can be made of synthetic resin instead of metal. [Explanation of symbols]
