Description

Technical Field

[0001] The present invention relates to a cable support tool that can be fixed to a plurality of cable racks having different parent beam dimensions with a simple operation.

Background Art

[0002] In wiring work, after wiring a cable inside a laid cable rack, when further adding cables, it may be impossible to lay cables inside the rack. For example, when adding a weak current cable, a separator is required, so it is impossible to lay a cable inside the rack after wiring the cable. Therefore, the use of a suspension bolt can be considered instead of the cable rack.

[0003] The applicant has previously proposed a cable support tool fixed to a suspension bolt (Patent Document 1). This cable support tool has a configuration in which a cable support tool having a substantially J-shaped side is fixed to a suspension bolt. That is, a pair of clamping tools that sandwich both sides of the suspension bolt are provided, and the upper end of the cable support tool is screwed and fixed to each clamping tool.

[0004] In addition, the applicant has also proposed a pipe support tool fixed to a cable rack (Patent Document 2). This pipe support tool has a configuration in which a pipe is supported by the parent beam of the cable rack. According to this configuration, it has a structure in which it is fixed to the parent beam by an upper fitting that locks inside the horizontal edge of the parent beam and a lower fitting that locks from the outer surface to the lower surface of the parent beam, and the pipe is supported by the fixed upper fitting.

Summary of the Invention

Problems to be Solved by the Invention

[0006] When adding cables using the cable support device described in Patent Document 1, the wide spacing of the suspension bolts causes the cables to sag, resulting in an unsightly appearance.

[0007] Therefore, in order to fix the cable support to the cable rack instead of using suspension bolts, a structure is needed in which the cable support is fixed to the main beam using an upper fitting that engages with the upper end of the main beam and a lower fitting that engages with the bottom from the outer surface of the main beam, as described in Patent Document 2.

[0008] However, since cable racks typically use multiple types with different main beam dimensions, if the upper and lower fittings are designed to fit one type, it becomes inconvenient as they cannot be used with other types that have different main beam dimensions.

[0009] Furthermore, conventional cable and pipe supports require the installation of multiple components, such as upper and lower fittings, using screws or other fasteners, which poses a significant challenge in terms of the effort involved in fixing the supports in place. Additionally, manufacturing separate supports for each type of cable rack presents manufacturing cost challenges.

[0010] Therefore, 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 multiple types of cable racks and that is extremely easy to fix. [Means for solving the problem]

[0011] To achieve the above objective, the first means in the present invention is a support 10 that supports a cable P, etc., A cable support comprising a fixing body 20 for fixing the support body 10 to the main beam 1 of a cable rack having a pair of lip portions 2A and side plates 2 connecting the lip portions 2A, The support body 10 comprises a connecting portion 11 that hangs down along the outer surface of the side plate 2, and a support portion 10 that extends from the connecting portion 11 and supports the cable P. The fixing body 20 is provided with a contact piece 21 that abuts against the outer surface of the lip portion and a locking projection 24 that extends from the contact piece and abuts against the inner surface of the lip portion 2A.

[0012] The support 10 of the second means is in surface contact with the outer surface of the side plate 2.

[0013] The third means of the fixing body 20 further comprises a bent piece 23 that abuts against the inner surface of the side plate 2.

[0014] The fourth means, the bent piece 23, has a surface shape and makes surface contact with the inner surface of the side plate 2.

[0015] The fifth means is provided between the contact piece 21 and the locking projection 24 and includes an elastic portion 22 that wraps around to the inner surface side of the lip portion 2A.

[0016] The bent piece 23 of the sixth means is a portion that is bent diagonally downward from the tip of the elastic portion 22. The locking projection 24 is formed via a pair of left and right notches 24A that are formed diagonally outward from the bending portion between the elastic portion 22 and the bending piece 23 toward the bending piece 23, and when the bending piece 23 is bent downward, the locking projection 24 is formed to rise diagonally upward from the notches 24A.

[0017] The seventh means is to arrange the support 10 and the fixing body 20 on the outer and inner sides of the lip portion 2A, respectively. When the support 10 is rotated toward the side plate 2, The locking projection 24 abuts against the inner surface of the lip portion 2A, and the support 10 abuts against the outer surface of the side plate 2.

[0018] The eighth means includes a support 10 for supporting a cable P or the like, a fixing body 20 for fixing the support 10 to the main beam 1 of a cable rack having a pair of lip portions 2A and a side plate 2 connecting the lip portions 2A to each other. The cable support device is provided with: the fixing body 20 has elasticity, with the support 10 and the fixing body 20 respectively arranged on the outer surface side and the inner surface side of the lip portion 2A, when the support 10 is rotated toward the side plate 2, the fixing body 20 abuts against the inner surface of the lip portion 2A, and the support 10 abuts against the outer surface of the side plate 2.

Advantages of the Invention

[0019] As in the present invention, by configuring the tip of the bending piece 23 to be locked to the inner surface of the side plate 2, the connecting portion 11 is attached so as to contact the side plate 2. As a result, it becomes possible to be commonly used for the main beams 1 of several types of cable racks. Moreover, since the support 10 and the fixing body 20 are integrally formed of a strip material, the mounting work becomes easy. Also, the problems in manufacturing cost are solved.

Modes for Carrying Out the Invention

[0021] The cable support of the present invention supports cables P and PF pipes along the outer surface of the side plate 2 of a main girder 1 having a lip portion such as a cable rack or cable duct, and the support body 10 and the fixing body 20 are integrally formed. The support body 10 is the part that supports the cable P, etc., and is arranged on the outer surface of the side plate 2 (see Figure 7).

[0022] The support body 10 comprises a connecting portion 11 that hangs down along the outer surface of the side plate 2, and a support portion 12 that is bent from the tip of the connecting portion 11 to support the cable P (see Figure 1), and makes surface contact with the outer surface of the side plate 2 (see Figure 4(c)). A cover portion 13 is formed from the connecting portion 11 to the support portion 12 (see Figure 3). This cover portion 13 protects the cable P that is attached to the support body 10 and is formed of vinyl coating or the like.

[0023] Furthermore, the connecting portion 11 contacts the side plate 2 to prevent the support 10 from shaking. In addition, the cover portion 13 also contacts the side plate 2 to prevent shaking.

[0024] The fixing body 20 is a strip-shaped elastic part that is fixed to the side plate 2 of the main beam 1 of the cable rack. The fixing body 20 is composed of a contact piece 21, an elastic part 22, a bending piece 23, and a locking projection 24 (see Figure 1).

[0025] The contact piece 21 is the part that contacts the upper surface of the lip portion 2A of the side plate 2. In the illustration, the contact piece 21 is in contact with the upper surface of the lip portion 2A of the cable rack, but it can also contact the main beam 1 of a cable rack such as a cable duct that has a similar lip portion. The elastic portion 22 is the part that extends in an arc shape from the tip of the contact piece 21 and wraps around to the inner surface of the lip portion 2A (see Figure 5).

[0026] These contact pieces 21, elastic parts 22, and bending pieces 23 are pre-formed to fit larger steel troughs 1, i.e., the longer side plates 2 of the lip section 2A, so that they can accommodate the main beam 1 of cable racks of different sizes (see Figures 5 and 6). When attached to a shorter side plate 2, they can also support the cable P on the underside of the side plate 2.

[0027] On the other hand, the bent piece 23 is a surface-shaped portion that is bent diagonally downward from the tip of the elastic portion 22 (see Figure 2), and it makes surface contact with the inner surface of the side plate 2 (see Figure 4(c)). The tip of this bent piece 23 is formed to contact the inner surface of the side plate 2 when the fixing body 20 is fixed to the lip portion 2A (see Figure 4(c)). As the bent piece 23 engages with and braces the inner surface of the side plate 2, the connecting portion 11 comes into contact with the side plate 2, and the connecting portion 11 becomes aligned with the side plate 2.

[0028] The locking projection 24 is formed as an extension 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 side plate 2 (see Figures 5 and 6). That is, when the fixing body 20 is attached to the lip portion 2A of the side plate 2, the tip of the locking projection 24 is configured to contact the inner surface of the lip portion 2A (see Figure 4(c)).

[0029] The locking projection 24 shown in the figure is formed via a pair of left and right notches 24A that are formed diagonally outward from the bending portion between the elastic portion 22 and the bending piece 23 in the direction of the bending piece 23 (see Figure 2). When the bending piece 23 is bent downward, the locking projection 24 is formed to rise diagonally upward from the notches 24A.

[0030] In this case, the upper end of the locking projection 24 is formed to protrude upward from the contact piece 21 through a pre-formed notch 21A in the contact piece 21 (see Figures 1 and 2). This makes it possible to strengthen the clamping force on the lip portion 2A of the side plate 2 that is clamped between the contact piece 21 and the locking projection 24 (see Figures 5 and 6).

[0031] Furthermore, by integrally forming the support 10 and the fixing body 20 with a strip plate, the gap between the support 10 and the side plate 2 can be eliminated, so that a cover that seals the opening of the main beam 1 of the cable rack can be attached even after the support 10 has been installed (not shown). In addition, even without the bending piece 23, the cover can be attached by pushing the connecting part 11 toward the side plate 2 and bringing it into contact with the side plate 2.

[0032] The support of the present invention can be attached to the side plate 2 with a simple operation (see Figures 4(a) to (c)). Specifically, as shown in (a), the support body 10 is placed on the upper surface of the lip portion 2A of the side plate 2, and the fixing body 20 is positioned on the lower side of the lip portion 2A. Next, as shown in (b), the support body 10 is rotated toward the side plate 2, and as shown in (c), the fixing body 20 is attached with the locking projection 24 of the fixing body 20 locked to the lower surface of the lip portion 2A of the side plate 2.

[0033] Subsequently, the bent piece 23 contacts and locks against the inner surface of the side plate 2 (see Figures 5 and 6). As a result, the locking projection 24 and the bent piece 23 simultaneously lock with the lip portion 2A of the side plate 2 and the side plate 2, resulting in an extremely strong locking force.

[0034] Furthermore, the configurations of the present invention are not limited to those shown in the illustrations, and design modifications are permitted as long as they do not alter the essence of the invention. For example, the support bracket can be made of a synthetic resin material in addition to a metal material. [Explanation of Symbols]
