Description

[Detailed description of the invention] (Industrial field of application) The invention relates to a cable ladder halter.
More specifically, the present invention relates to a halter that is attached to a cable ladder for organizing cables such as power lines and communication lines of various communication devices and transport devices.

(Prior Art) Conventionally, various types of halters have been provided. For example, as shown in FIG. 4, a through hole 21a that matches the through hole 11a previously provided in the main beam material 11 of the cable ladder is formed in the substrate 21, and this substrate 21 is brought into contact with the inner surface of the main beam material 11. In the case of the halter H', which is fixed with bolts, nuts, etc., the work of drilling the through holes 11a for attachment in the main girder material 11 is complicated, and the work of drilling the through holes 11a in the main girder material 11
There was a drawback that the strength of the part where a was provided was weakened.

On the other hand, another halter H'' consists of a base plate 22 and an auxiliary plate 23, both of which are attached so as to straddle the main girder material 11, and screw holes 22a formed in the base plate 22 and the auxiliary plate 23, If the bolt is screwed into 23a, the main girder material 1
There is no need to provide a through hole 11a in 1, and there is no drawback like the above-mentioned halter H', but the common drawbacks of these halters H' and H'' are: (a) The large number of parts leads to increased cost and weight. (b) It is easy to install the main girder 11, requiring a large number of man-hours, and requires a lot of effort and time. (c) A tool such as a ratchet spanner is required when attaching to the main girder 11.

(Purpose of the invention) This invention was proposed to solve the above-mentioned drawbacks, and its purpose is to provide a holder that is attached to the main girder of the cable ladder and a board that is fixed to this holder. The object of the present invention is to provide a halter for a cable ladder which, by having such a structure, eliminates all of the various drawbacks mentioned above and enables dramatic improvements in economical efficiency, workability, etc.

(Structure of the idea) The present invention will be explained below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, which is comprised of a substantially rectangular board 1 and a holder 2 for fixing the board 1 to a main beam member of a cable ladder. That is, the substrate 1 is formed by cutting a steel plate or the like into strips, and is provided with a wedge-shaped end 1a formed at one end in the length direction so that the wall thickness becomes gradually thinner. A locking groove 1b extending in the horizontal direction is provided at the upper end of the portion 1a.
is recessed.

On the other hand, the holder 2 is formed by bending a thin steel plate or the like into a U-shape when viewed from the side, and the upper support piece 2b connected to the upper edge of the base piece 2a has a size sufficient to allow the board 1 to pass through. A through hole 2c is bored therein, and a lower support piece 2d connected to the lower edge of the base piece 2a has a width slightly narrower than that of the through hole 2c, and a wedge-shaped end of the base piece 1 is formed in the lower support piece 2d. A locking hole 2e is formed with a size such that the locking hole 2e is inserted through the locking groove 1b and the locking groove 1b is locked to the inner peripheral edge. In addition, base piece 2
The width a, in other words, the distance between the upper support piece 2b and the lower support piece 2d, is set to match the width of the main girder of the cable ladder to which the present invention is attached.

To use this, as shown in FIG.
The holder 2 is attached to the parent girder material 11 from the inside, and then the board 1 is inserted into the through hole 2c and the locking hole 2e from above.
, and the locking groove 1b of the substrate 1 only needs to be locked to the inner peripheral edge of the locking hole 2e. By doing so, the substrate 1 and the holder 2 are integrally and firmly fixed so that the parent beam material 11 is sandwiched therebetween. In addition, in FIG. 2, C indicates a cable.

Next, FIG. 3 shows another embodiment of the present invention. In this embodiment, the holder 2' has a spring property.
The base piece 2a' is curved so as to protrude toward the board 1', and the locking piece 2f is attached to the lower support piece 2d' without providing the support hole 2e as shown in FIG. The lower end portion of 1' is configured to be locked inside the locking piece 2f. According to this embodiment, the upper support piece 2b' and the lower support piece 2d' tend to be pulled in the direction of the child beam member 12 by the curved base piece 2a', so that the base plate 1' is more firmly fixed. There is an advantage that it can be done. Here, base piece 2
It goes without saying that the idea of curving a' can also be applied to the embodiment shown in FIG.

(Effect of the invention) As described above, according to the invention, from the base piece that comes into contact with the main beam member of the cable ladder, and the upper support piece and the lower support piece attached to the upper and lower edges of this base piece, respectively. The holder has a substantially U-shaped side surface, and a substrate that passes through the upper support piece of the holder attached to the parent girder member and whose lower end is locked to the lower support piece. This allows for one-touch and secure installation to the cable ladder by sandwiching the main girder material, compared to conventional methods. (a) Reduces the number of parts, which reduces costs and reduces the overall weight of the halter. (b) Because there is no need to fix screws. It has the advantage of being convenient because no tools are required when attaching it to the parent girder material.
