Description

[Detailed description of the invention] (Field of industrial application) This invention is a wiring device used when attaching lighting equipment, covers, and other wiring devices to channel materials used as ducts and raceways during electrical equipment construction. Regarding support fittings.

(Prior Art) Conventionally, when installing a lighting fixture or the like to a channel material such as a duct, a predetermined mounting bracket having a connecting bolt is installed in the opening of the channel material. At this time, in order to make it easier to attach the mounting bracket to the channel material, attach the connecting bolt of the mounting bracket to the
This is a support bracket for wiring equipment that is equipped with an elastic clamping plate that presses against the opening of the channel material, making it easy to install the mounting bracket, and also allows the mounting position on the channel material to be freely adjusted by sliding. Already proposed by the applicant (for example, Utility Model Publication No. 49-16875 and Utility Model Publication No. 49-21595)
issue).

These supporting metal fittings are fixed to the lip part of the channel material, a mounting metal fitting that locks inside the channel material, and a connecting bolt that protrudes from the mounting metal fitting to the outside of the channel material. It consists of an elastic clamping plate that temporarily fastens the mounting bracket to the opening, and is configured to temporarily clamp the mounting bracket by pressing this elastic clamping plate against the outside of the lip of the channel material. be.

Furthermore, 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 state of engagement is tight. Therefore, even if the elastic clamping plate is pressed against the outside of the lip portion and the mounting position of the mounting bracket is slid along the channel material, the mounting bracket and the lip portion will not separate and can be freely adjusted in position. This is how it was done.

(Problem to be solved by the invention) However, in the case of the above-mentioned support fittings, if the lip part does not have a fold toward the inside of the channel material, or even if the lip part has a fold,
In cases where the mounting bracket does not have a bent part that fits into this fold, the engagement between the mounting bracket and the lip becomes more uncertain as the load applied to the mounting bracket decreases. It was not possible to always engage the parts in a stable manner. 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 rotates and comes off from the channel material. There was a concern (see Figure 6).

In addition, if the lip part does not have a folded part facing inside the channel material (if the tightening allowance when clamping the lip part is only the thickness of the lip part), the tightening allowance by the connecting bolt and nut will be almost the same. However, there was a problem in that it was difficult to securely and firmly fix the lighting equipment to the channel material.

(Means for Solving the Problems) Therefore, the present invention solves the above-mentioned difficulties, and also allows the mounting bracket to be kept in a stable state at all times on the lip of the channel material, regardless of the shape of the channel material or the mounting bracket. It was devised to provide a supporting metal fitting for wiring devices, etc., which can be temporarily fixed and fixed, and which can reliably prevent it from falling off when adjusting the slide.

Furthermore, the bent fitting portion 1C of the clip 1 serves as a tightening margin when the lighting fixture Q is attached to the channel material P using the support fittings, and
The spring action firmly attaches the lighting fixture Q to the channel material P.

(Example) Hereinafter, the present invention will be described in detail with reference to illustrated examples.

The present invention is a support metal fitting used when attaching a lighting fixture Q, a cover, and other wiring devices to a channel material P used as a duct or raceway during electrical equipment construction. The clamping element 1 is secured to the inner side of P1, the temporary fixing plate 2 is pressed against the outer side of the lip part P1 of the channel material P, and the lighting is inserted through the clamping plate 1 and the temporary fixing plate 2. It consists of a connecting bolt 3 that connects and fixes wiring devices such as the appliance Q.

The clipper 1 has a pair of parallel short side edges 1A whose width is narrower than the width of the opening of the channel material P.
and a pair of parallel longitudinal side edges 1B that are wider than the width of the opening of the channel material P and have a length that allows the lip portions P1 to be engaged with each other.
Both end corners of one long side edge 1B are notched to provide a cutout portion 1D, and the clipper is cut out so that the cutout portion of one long side edge 1B slightly protrudes outward from the opening portion of the channel material P. 1 is bent into a substantially dogleg shape to form a bent fitting portion 1C that is fitted and locked between the distal edges of the lip portion P1.

In the illustrated example, the shape of the notch 1D obtained by cutting out both ends of one longitudinal side edge 1B is approximately an arc shape, and even if the spacing between the lip parts P1 is slightly different, the fitting of the bent fitting part 1C is The locking mechanism is designed to accommodate this. Furthermore, since the cutout portion 1D is rounded, movement along the lip portion P1 can be performed more smoothly.

Furthermore, the bending angle of the bending fitting part 1C is formed at an angle such that the tip of the bent bending fitting part 1C comes into pressure contact with the wiring equipment such as the lighting fixture Q connected with the connecting bolt 3 (see Fig. 4). reference). That is, the pincer 1
The cross section of the clip is substantially dogleg-shaped, and the elasticity of the clip 1 itself is utilized to enable vertical and firm attachment.

The temporary fixing plate 2 is made of a plate made of plastic or the like, and is brought into contact with the outer side of the lip portion P1 of the channel material P, and has a bolt insertion hole 2A through which the connecting bolt 3 protruding from the clip 1 is inserted. A hole is drilled in the center of the board surface (see Figure 2). At this time,
The temporary fixing plate 2 has a transparent planar circular shape whose diameter is approximately equal to the width of the channel material P. Note that the temporary fixing plate 2 is not limited to the illustrated example, and may have a rectangular shape or other appropriate shapes.

By the way, the specific configuration, shape, dimensions and material of the clamping element 1, the specific shape and dimensions of the bending fitting part 1C,
The specific shape and dimensions of the cutout portion 1D, the specific configuration, shape, dimensions, and material of the temporary fixing plate 2, and the specific configuration, shape, dimensions, and material of the connecting bolt 3 are not limited to the illustrated examples, etc. This can be set freely as appropriate.

(Effects of the invention) Therefore, the present invention provides a clamping member 1 that is locked on the inside of the lip portion P1 of the channel material P, and a temporary fixing plate that is pressed against the outside of the lip portion P1 of the channel material P. 2, and a connecting bolt 3 that passes through the clip 1 and the temporary fixing plate 2 and connects and fixes wiring devices such as the lighting fixture Q.
In the supporting metal fitting, the clipper 1 has a pair of parallel short side edges 1A that are narrower than the width of the opening of the channel material P, and a pair of parallel short side edges 1A that are wider than the width of the opening of the channel material P. , the lip part P1 has a substantially rectangular plate shape with a pair of parallel longitudinal side edges 1B having a length that can be locked with each other, and both end corners of one of the longitudinal side edges 1B are cut out to form a notch 1D. At the same time, the clipper 1 is placed so that the notched one longitudinal side edge 1B slightly protrudes outward from the opening of the channel material P.
The bent fitting part 1C of the clip 1 is bent into a substantially dogleg shape to form a bent fitting part 1C that is fitted and locked between the tip edges of the lip part P1.
At the same time, the notches 1D of the clipper 1 are respectively locked to the tip edge portions of the lip portion P1, and the support fittings are slid along the channel material P for sliding adjustment. When sliding the clip with the channel material P, it is now possible to reliably prevent the clipper 1 from rotating within the channel material P, and it is also possible to reliably prevent the mounting bracket from falling off, which frequently occurs when adjusting the slide. The support fitting of the present invention can be temporarily fixed to the lip portion P1 in a stable manner at all times.
In addition, the clipper 1 and the temporary fixing plate 2 can clamp the lip portion P1 and stably maintain the temporarily fixed state of the supporting metal fitting of the present invention.

In particular, the clip 1 is bent into a substantially dogleg shape so that one long side edge 1B slightly protrudes outward from the opening of the channel material P, and the clip is fitted between the tip edges of the lip portion P1. Since the bent fitting part 1C to be locked is formed, the bending fitting part 1C of the clip 1 can be fixed when the lighting fixture Q is attached to the channel material P using the support fittings. In addition to providing a tightening margin, the spring action allows the lighting fixture Q to be firmly attached to the channel material P. That is, even if the lip part P1 does not have a folded part facing inside the channel material P (in a case where the tightening margin when pinching the lip part P1 is only the thickness of the lip part P1), the bending fitting part 1C The portion serves as a tightening margin between the connecting bolt 3 and the nut, and the state of fixation of the lighting fixture Q to the channel material P becomes more reliable and strong.
