Description

[Detailed description of the invention] (Field of industrial application) This invention is a wiring device used when installing lighting equipment, covers, and other wiring devices to channel materials used as ducts and raceways in electrical equipment construction. Related to temporary fasteners for supporting metal fittings such as.

(Prior Art) Conventionally, in the work of attaching lighting equipment, etc. to a channel material such as a duct, a predetermined mounting bracket having a connecting bolt is sometimes installed in an opening in which a lip portion of the channel material is formed. At this time, in order to make it easier to attach the mounting bracket to the channel material, an elastic clamping plate is provided on the connecting bolt of the mounting bracket to make pressure contact with the opening of the channel material. Supporting metal fittings for wiring devices whose position can be slid and adjusted have been previously proposed by the present applicant (Utility Model Publication No. 49-16875 and Utility Model Number 16875).
49-21595).

This application includes a mounting bracket that locks inside the channel material on the lip part of the channel material, and a connecting bolt that protrudes from the mounting bracket to the outside of the channel material, and is attached to the opening of the channel material. It consists of an elastic clamping plate that temporarily fixes the metal fittings. This elastic clamping plate temporarily fixes the mounting bracket by pressing it against the outside of the lip of the channel material.

In such conventional mounting brackets, the mounting bracket itself is bent into a substantially wave-shaped side surface in order to fit into the shape of the lip part that is folded inward into the channel material. The engagement state is in a tight state. Therefore, even if the elastic clamping plate is pressed against the outside of the lip and the mounting position of the mounting bracket is slid along the channel material, the mounting bracket and the lip will not separate and the position can be adjusted freely. It's something you get.

(Problem to be solved by the invention) However, when the lip part does not have a fold inward toward the inside of the channel material, or even if the lip part has a fold, there is no bent part on the mounting bracket that fits into the fold. The state of engagement between the mounting bracket and the lip becomes more uncertain as the load applied to the mounting bracket decreases, and it is not possible to always maintain a stable engagement between the mounting bracket and the lip. . As a result, when the mounting bracket is slid along the channel material when the temporary fixing state is as described above, the mounting bracket that is locked inside the lip part rotates naturally, and the mounting bracket comes off from the channel material. (See Figure 5).

Therefore, this idea was devised to solve the above-mentioned inconvenience, and regardless of the shape of the channel material or the mounting bracket, the mounting bracket can be temporarily fixed to the lip of the channel material in a stable state at all times, and the slide adjustment can be adjusted. The purpose of the present invention is to provide a temporary fixing device for supporting metal fittings such as wiring devices, which can prevent the metal fittings from falling off at times.

(Means for Solving the Problems) In order to achieve the above-mentioned object, this invention has a clipper 2 that locks inside the lip portion P1 of the channel material P.
and a connecting bolt 3 that extends from the clip 2 and connects and fixes wiring devices such as a lighting fixture Q. A temporary fixing for a supporting metal fitting is used to temporarily fix the supporting metal fitting 1 to the lip part P1 of the channel material P. In the tool, the temporary fastener 4 is attached to the lip portion P1 of the channel material P.
An elastic clamping plate 5 that presses against each other is formed, and the elastic clamping plate 5 has a bolt insertion hole 5A through which the connecting bolt 3 is inserted, a clamping piece 5B that fixes the elastic clamping plate 5 to the clamping element 2, and a lip portion. A means to solve this problem is to provide a fitting portion 5C that fits between the opposing side edges of P1.

(Function) That is, according to this invention, the elastic clamping plate 5 forming the temporary fastener 4 is pulled along the connecting bolt 3 of the support fitting 4 that is locked inside the lip portion P1 of the channel material P. The parts P1 are pressed against each other on the outside.

The clamping piece 5B provided on the elastic clamping plate 5 is
The temporary fastener 4 is fixed to the clamp 2 by clamping both longitudinal edges of the clamp 2.

Furthermore, the fitting portion 5C provided on the elastic clamping plate 5 is fitted between the opposing side edges of the lip portion P1, and functions to prevent rotation when the support fitting 1 is slid.

(Example) Hereinafter, an example of this invention will be described in detail with reference to the drawings.

Reference numeral 1 shown in the figure is a support fitting for supporting and connecting wiring devices such as a lighting fixture Q to a channel material P (see FIG. 1). This support fitting 1 has a clip 2 that locks inside the lip portion P1 of the channel material P.
and a connecting bolt 3 extending from the clip 2. The illustrated pincer 2 is as follows:
In order to increase its supporting strength, reinforcing ribs 2A are provided along its longitudinal direction. A temporary fixing tool 4 is used to temporarily fix the clip 2 inside the lip portion P1 of the channel material P.

The temporary fastener 4 is an elastic clamping plate 5 made of plastic or the like.
The elastic clamping plate 5 is brought into contact with the outer side of the lip portion P1 of the channel material P.
A bolt insertion hole 5A through which a connecting bolt 3 extending from the clip 2 is inserted is bored in the center of the plate surface (see FIG. 2). And this bolt insertion hole 5
On both sides of A, clamping pieces 5B for clamping the longitudinal side edges of the clamping element 2 are provided. The illustrated clamping piece 5B is formed by providing a notch in the surface of the elastic clamping plate 5 and bending a part of the elastic clamping plate 5 toward the clamping member 2 from this notch. Moreover, this clamping piece 5B is, for example,
It may be a separate piece from the elastic clamping plate 5 and glued to the elastic clamping plate 5, and in short, any material that can fix the elastic clamping plate 5 and the clamping element 2 may be used.

Then, the portion of the elastic clamping plate 5 that contacts the lip portion P1 is bent toward the inside of the channel material P along the lip portion P1 to provide a bent portion 5C, and a bolt insertion hole 5A and a clamping piece 5B are provided. The plate surface of the elastic clamping plate 5 fits between the opposing side edges of the lip portion P1,
It is designed to slide on this inner side (see Figure 3). At this time, the elastic clamping plate 5
It has a transparent planar circular shape with its width equal to its approximate diameter. (See Figure 4). In addition, the elastic clamping plate 5
is not limited to the illustrated example, but may have a rectangular or other shape.

(Effects of the invention) This invention achieves its original purpose by being configured as described above.

That is, a support metal fitting consisting of a clip 2 that locks inside the lip portion P1 of the channel material P, and a connecting bolt 3 that extends from the clip 2 and connects and fixes wiring equipment such as a lighting fixture Q. 1 to the lip part P1 of the channel material P, the temporary fixture 4 forms an elastic clamping plate 5 that presses against the lip part P1 of the channel material P, This elastic clamping plate 5 has a bolt insertion hole 5A through which the connecting bolt 3 is inserted, a clamping piece 5B which fixes the elastic clamping plate 5 to the clamping element 2, and a clamping piece 5B that is fitted between opposing side edges of the lip portion P1. By providing the fitting portion 5C, the mounting bracket 1 can be temporarily fixed to the lip portion P1 of the channel material P in a stable state at all times.

Moreover, even if the lip part P1 does not have a fold toward the inside of the channel material P, or even if the lip part P1 has a fold, there is no bent part on the mounting bracket 1 that fits into the fold. The clamping piece 5B provided on the elastic clamping plate 5 and the fitting part 5C prevent rotation of the mounting bracket 1 with respect to the temporary fixture 4 and prevention of falling off of the temporary fixture 4 with respect to the lip part P1. Therefore, it is possible to reliably prevent the mounting bracket 1 from falling off, which has frequently occurred during sliding adjustment of the mounting bracket 1 and the like.

In this way, according to this invention, the mounting bracket can be temporarily fixed to the lip of the channel material in a stable manner at all times, regardless of the shape of the channel material or the mounting bracket.
It has various practical effects such as being able to reliably prevent slides from falling off during adjustment.
