Description

[Detailed description of the invention] [Technical field of the invention] This invention relates to an electric wire/cable holder for wiring troughs, and is a rip channel steel structure called a raceway for various types of wiring in buildings, factories, etc. By using the wiring gutter facing downward, it prevents the stored electric wires and cables from hanging downward when supporting lighting equipment, for example, and allows for simple and quick installation even after the wiring gutter has been installed. The present invention relates to a holder made of

[Technical background of the invention and its problems] Conventionally, wiring troughs have been made using lip-groove steel as a dual-metal wire pipe. It is installed with the opening facing downward or upward depending on the wiring situation of electric wires, cables, etc. At that time, they are often used facing downwards to prevent dust from entering the interior and to facilitate branching of wiring to the various devices to be installed. However, if the wires are placed facing downwards, the stored electric wires, etc. will hang down below the opening, which is unsightly and dangerous. Prevents it from falling off. If this construction method is used, winding work must be performed for each line to be separated, and covers that close the openings must be installed and removed when painting after construction. It was hot. Not only that, but if the lip of the wiring gutter itself is bent inward and bent, when an electric wire or the like touches the inner part of the lip, it will engage the lip to attach equipment. Crush the wires etc. with a nut,
Insulation failure accidents also occurred.

In view of these drawbacks, many of the above-mentioned drawbacks were solved by the grooved rod cable holder disclosed in Japanese Utility Model Publication No. 35-22757, which was proposed in the past. Since it is formed as a main body with a substantially U-shaped front face that fits closely to the inner surface of the gutter, it has to be inserted into the wiring gutter by sliding it from its end. Therefore, it cannot be installed directly at the required location, it must be set in advance before installation during on-site construction, and it is extremely difficult to install it after the wiring gutter has been installed.

[Purpose of the invention] This invention was devised in view of the above-mentioned points, and it is possible to install the wiring gutter after it has been installed, and to quickly respond to the addition of electric wires, etc.
The purpose of this is that there is no need to remove the cover when closing or painting the cover, and there is no risk of insulation failure due to equipment nuts when installing various equipment.

[Summary of the invention] In order to achieve the above-mentioned object, this invention forms a mounting support piece curved in an arc shape, which is inserted into the wiring gutter made of lip channel steel through an opening thereof, and
A pair of left and right blocking pieces curved in the opposite direction to the curving direction of the mounting support piece are integrally extended inward from both ends of the mounting support piece, and the outer surface of the deep bottom of the mounting support piece is connected to the bottom of the wiring gutter. This consists in that the outer surface of the deep bottom part of the obstructing bullet is brought into pressure contact with the inner edge surface of the lip part, and the outer surfaces of the obstructing bullet are brought into relative contact with each other so that they can be opened and closed elastically. be.

[Embodiments of the invention] Hereinafter, embodiments of the invention will be described with reference to the drawings.

Reference numeral 1 shown in the figure is a mounting support piece, which is swivelingly inserted from the opening of D into a wiring gutter D as a raceway made of lip channel steel with a cross-section of 〓-shaped, 〓-shaped, 〓-shaped. It is curved into an arc.

A pair of left and right blocking pieces 2 are curved from both ends of the mounting support piece 1 in a direction opposite to the curve direction of the mounting support piece 1.
are integrally extended inward of the mounting support piece 1, and the outer surfaces of the closing bullet pieces 2 are brought into relative contact with each other so as to be elastically openable and releasable. That is, the opening of the mounting support piece 1 is closed by the mutually contacting portion 3 of the blocking pieces 2, so that when the electric wire/cable W is brought along the curved outer surface, The blocking bullet pieces 2 are forcibly separated from each other, and electric wires etc. are housed inside.

The entire body consisting of the mounting support piece 1 and the pair of blocking bullet pieces 2 has a substantially heart-shaped outer shape when viewed from the front, and is made of a strip material of an appropriate width that does not stand upside down even when placed on one side of itself. By curving it, it is made of synthetic resin such as vinyl chloride resin, spring steel, etc., and has high elasticity.

Further, the outer surface of the inner bottom of the mounting support piece 1 is pressed against the inner surface of the inner wall of the wiring gutter D, and the outer surface of the inner bottom of the blocking bullet piece 2 is pressed against the inner edge surface of the lip portion L, respectively.
Therefore, the distance between the outer surface of the deep bottom of the mounting support piece 1 and the inner surface of the deep bottom of the blocking bullet piece 2 in the depth direction of the mounting support piece 1 is the same as the distance between the inner surface of the deep wall of the wiring gutter D and the inner edge of the lip portion L. The free ends of the obstructing bullets 2 are in contact with each other in their original form before installation, but after installation they may become warped in opposite directions (the first (See Figures 2 and 3).

In the figure, reference numeral 4 denotes a locking claw piece that locks on the inner surface of the side wall of the wiring gutter D or the inner surface of the lip portion L, and extends outward from both ends of the mounting support piece 1. The locking claw piece 4 shown in the figure is formed by bifurcating from the closing bullet piece 2 at the end of the mounting support piece 1.Instead, although not shown, the mounting support piece 1 itself In some cases, it is formed by making a U-shaped cut and folding it up. By means of this locking claw piece 4, when a rocking force is applied from the outside when inserted into the wiring gutter D, this devised holder is secured by being locked to the side wall or lip portion L. For example, when an electric wire, etc., brought from between the lip parts L applies a pressing force to only one of the blocking bullet pieces 2 and tries to cause it to swing, this is prevented. This makes it easy to store electric wires, etc., and also reliably prevents them from falling out from between the lip parts L by swinging to either side after being inserted into the wiring gutter D. .

Next, an example of the installation procedure will be explained with reference to FIG. 4. At the position where the plug should be installed in the wiring gutter D, press the outside of the opposing contact portion 3 of the blocking bullet 2 against either one of the lip portions L. Seshime (see A in the same figure),
Swing it around the part pressed against the lip part L so that it can be inserted into the wiring gutter D (see B in the same figure),
While sliding the outer surface of the mounting support piece 1 onto the inner edge surface of the other lip part L (see C in the same figure), insert the entire mounting support piece 1 into the wiring gutter D.
The mounting support piece 1 may be placed in a state in which the outer surface of the deep bottom part is pressed against the inner surface of the inner wall of the wiring gutter D, and the outer surface of the inner bottom part of the blocking bullet piece 2 is pressed against the inner edge surface of the lip portion L (same as above). (See Figure D). Next, as shown in Figure 2,
It is sufficient to insert the electric wire or the like W from the outside of the relative contact portion 3 of the blocking bullet 2 by pushing it in, and to support it by placing it inside the blocking bullet 2.

[Effect of the invention] Therefore, since the electric wire/cable W is supported by being attached internally to the wiring gutter D, the wiring gutter D
Even if the openings of the wiring gutter D face downward, they are installed at predetermined intervals to prevent the electric wires W from sagging, and even after the wiring gutter D has been installed because they can be installed directly at the predetermined position of the wiring gutter D. It can be installed and provides extremely superior workability compared to conventional products.
Moreover, since the relative contact portion 3 that serves as a storage opening for supporting electric wires etc. W and the opening of the wiring gutter D coincide with each other, it is possible to easily add more electric wires etc. There is no need to remove the lid when closing or painting, and as shown in FIG. Electric wire etc. W
is supported by the blocking bullet 2, and the instrument nut N
Since it is located below the blocking bullet 2, the electric wire etc. W will not be crushed and accidents such as poor insulation will not occur.

In particular, since the mounting support piece 1 is curved in an arc shape to be inserted into the wiring gutter D through the opening of the wiring gutter D, the mounting support piece 1 is rotated with the opposing contact portion 3 pressed against the lip portion L. This makes it easy to install, and it is extremely convenient because it can be done directly at the installation position without having to slide inside the wiring gutter D.

In addition, a pair of left and right blocking pieces 2 which are curved in the opposite direction to the curving direction of the mounting support piece 1 are integrally extended inward from both ends of the mounting support piece 1, so that the entire structure is rounded. The fact that it is shaped like this also helps in making it easier to rotate it when it is installed. At the same time, since the outer surfaces of the blocking bullet pieces 2 are brought into contact with each other so as to be elastically openable and releasable, the insertion and support of electric wires, etc., can be carried out forcibly along the outer sides of the opposing contact parts 3, and once loaded, The inserted electric wire, etc. W is supported within the blocking bullet 2, so that it is not pulled out to the outside, and its support is stable.

In addition, since the outer surface of the inner part of the mounting support piece 1 is brought into pressure contact with the inner surface of the inner wall of the inner wall of the wiring gutter D, and the outer surface of the inner part of the inner part of the blocking bullet piece 2 is brought into pressure contact with the inner edge surface of the lip part L, the inner surface of the inner wall of the wiring gutter D is pressed. Since it is installed in a tensioned manner, it will not fall out of the wiring gutter D due to unexpected external force or the like.

As explained above, according to this invention, it is possible to prevent the stored electric wires and cables from hanging downward when the wire gutter made of rip channel steel is used facing downward, and to prevent the wires and cables from hanging downward after the electric wire gutter is installed. It is extremely easy to install as it can be directly attached to a predetermined position, and it also allows the addition of electric wires, etc., and there is no need to remove it when installing or painting the cover, and there is a risk of insulation failure due to equipment nuts when installing various equipment. In addition, it is inexpensive and can be integrally formed with a band-like material with high elasticity, which is extremely useful in practice.
