Description

[Detailed Description of the Invention] The present invention relates to a mounting device for electrical appliances, and its purpose is to facilitate installation.

Conventionally, as shown in Figure 1, the mounting device for electrical appliances such as direct-mounted lighting fixtures where the power line is drawn out approximately along the mounting surface has been to attach it to the mounting surface such as the ceiling or wall using wood screws, etc. A screw hole 1a which is a mounting part formed on a mounting plate 1 and an electric appliance main body 2
Align the screw insertion hole that is the mounting part of the flange part 3, which is a part of the
It is known that electric appliances are fixed by screwing them together. However, with such a mounting device, it is difficult to pinch the power wire 5 between the mounting plate 1 and the flange portion 3 during installation, damage the power wire 5 with the tip of the thumb screw 4, or damage the power wire 5 from the screw insertion hole of the flange portion 3. and mounting plate 1
The drawback was that the screw holes were difficult to align, making installation difficult.

The present invention was devised in view of the above-mentioned drawbacks, and is intended to prevent the power wire from becoming entangled and to facilitate the installation of electrical appliances onto the mounting surface.

The present invention will be explained below based on the embodiments shown in FIGS. 2 to 5. 1 is a mounting plate with a substantially U-shaped cross section, and is provided with a screw hole 1a into which a knob screw 4 is screwed. It can be attached with wood screws 6,6. Reference numeral 7 denotes a guide tool A having a substantially U-shaped cross section, and is fixed to the inner surface of the flange portion 3, which is a part of the electric appliance body, with a U-shaped vertical piece, and both U-shaped protruding pieces are attached to the mounting plate 1. The guide portion 7a is fitted into the guide portion 7a to position the mounting plate 1 and the flange portion 3 relative to each other in a direction parallel to the U-shaped cross section of the mounting plate 1. Further, on one U-shaped protruding piece of the guide tool A7, a wire stopper 7b for fixing the power supply wire 5 is formed outward in the U-shape, and the flange portion 3 and the guide fixed to the flange portion 3 are formed. A screw insertion hole 3a through which the knob screw 4 is inserted and an insertion hole 7c are provided through the tool A7. Reference numeral 8 denotes a guide tool B fixed to the inner surface of the flange portion 3, which blocks the end face of the mounting plate 1 and positions the mounting plate 1 and the flange portion 3 relative to each other in a direction perpendicular to the U-shaped cross section of the mounting plate 1. It has a mounting plate blocking part 8a which is a guide part to do this. Further, a projecting piece-shaped hook 8b is formed adjacent to the mounting plate blocking portion 8a of the guide B8, and is adapted to be caught on the U-shaped inner surface of the mounting plate 1, and is adapted to be hooked onto the U-shaped inner surface of the mounting plate 1, and is designed to be hooked onto the U-shaped inner surface of the mounting plate 1. The electrical appliance main body 2 is fixed to the mounting plate 1 together with a thumb screw 4 inserted through the hole 3a and screwed into the screw hole 1a of the mounting plate 1, and the electrical appliance is mounted on a mounting surface such as a ceiling surface.

When installing an electrical appliance, fit the guide tool A7 attached to the flange part 3 while ensuring that the hook 8b of the guide tool B8 does not touch the mounting plate 1 attached to the mounting surface such as the ceiling or wall. While maintaining the state, slide the appliance main body 2 along the axis perpendicular to the U-shaped cross section of the mounting plate 1, hook the hook 8b of the guide tool B8 on the U-shaped inner surface of the mounting plate 1, and then install. The end surface of the plate 1 is the mounting plate stop portion 8 of the guide tool B8.
Slide the electric appliance main body 2 until it comes into contact with a. Then, the screw insertion hole 3a of the flange portion 3 of the electric appliance main body 2 and the insertion hole 7c of the guide tool A7 are aligned with the screw hole 1a of the mounting plate 1, and the thumbscrews 4 can be inserted and screwed together. Electrical appliances can be installed. At this time, the power wire 5 of the electric appliance is fixed to the wire stopper part 7b of the guide tool A7, so that the power wire 5 will not be caught or damaged.

As shown in FIG. 6, the guide B8 includes a guide portion that fits onto the mounting plate 1 and positions the mounting plate 1 and the flange portion 3 relative to each other in a direction parallel to the U-shaped cross section of the mounting plate 1. If 8c is provided, positioning and fixing at the time of installation can be performed even more easily. In addition, if the guide tool A7 and the guide tool B8 are integrally formed and the guide part, wire stopper part, and mounting plate stopper part are provided, the guide tool and the electric appliance main body 2 can be fixed only once and assembled. becomes easier.

As described above, according to the present invention, the main body of the electrical appliance, from which the power line is drawn out approximately along the mounting surface, is attached to the mounting plate fixed to the mounting surface, and the positions of the mounting plate and the mounting portion of the electrical device main body are aligned. In a mounting device for an electrical appliance, the guide tool is formed in a substantially U-shape and has both projecting pieces protruding in the mounting direction of the electrical appliance body and is fitted onto a mounting plate to position the electrical appliance body. A wire stopper for fixing the power wire is formed on the outer surface of the protruding piece of the guide tool, and the wire stopper prevents the power wire from getting caught, etc., without complicating the structure. It has the advantage of being able to prevent scratches and allowing easy attachment of electrical appliances without impairing the guiding performance of the guide tool.
