Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a cover attachment device for covering the ceiling attachment part of the main body of a lighting fixture.

2. Description of the Related Art Conventionally, a substantially V-shaped curved spring has been widely used as a means for applying an upward biasing force to various covers of lighting equipment.

Problems to be solved by the invention In the above-mentioned conventional technology, the middle part of the stiff spring is
For example, it is typically used by attaching it to a fixture on the main body and slidably attaching both ends to guide fixtures on the cover, which requires both a fixture on the body side and a guide fixture on the cover side, which increases costs. There was a problem.

Therefore, the present invention aims to solve this problem.

Means for Solving the Problems The present invention involves attaching a base of a spring wire with a winding part that is an inflection point in the middle part to the upper part of the main body, and providing this spring wire in an upright manner. An upward biasing force is applied to the cover by tilting a portion closer to the end outwardly against elasticity and attaching the end to a cover that covers the ceiling mounting portion of the main body. Constructs a cover mounting device for lighting equipment.

Function According to the present invention, since the intermediate portion of the spring wire is not fixed, the above-mentioned mounting device is not required, and the intermediate portion can be moved as the spring wire is bent. In addition, since we used a spring wire with a winding part that serves as an inflection point in the middle, the spring wire can be easily bent.
Cover movement becomes smoother.

Embodiment An embodiment of the present invention will be described with reference to the accompanying drawings.

An annular fluorescent lamp 3 is attached to the lower part of the main body 1 via a support spring 2, and a shade 5 is supported on the collar 4 of the main body 1. The top surface of the main body 1 has a cross section of approximately U.
A shaped cord guide tool 6 is attached with screws 8 together with a tube 7 that covers the cord guide tool. The cord 9 is passed through the upper surface of the cord guide tool 6, and the connector 10 at the lower end is inserted into the upper surface of the main body 1 for connection. A cord stopper 11 is attached, for example, by caulking, to the middle portion of the cord 9 to prevent the cord 9 from coming off and to define the upward protrusion of the cord guide 6. A hook plug 12 is provided at the upper end of the cord 9, and this hook plug is attached to the ceiling 13.
Connect to the rosette 14 installed on the A spring wire 15 is provided upright on the upper part of the main body 1, that is, on both sides of the cord guide device 6, and its base is attached by cut-up claws 16, 17 formed on both sides of the cord guide device 6. A winding part 18 that serves as an inflection point is provided in the middle part of the spring wire 15 so that the spring wire 15 can be easily bent. is attached to a substantially bowl-shaped cover 19. This attachment is accomplished by inserting it into a tunnel-shaped attachment hole 20 formed at the upper end of the inner surface of the cover 19. A short tube 22 with an outward flange 21 is fitted to the upper end of the tube 7, for example, in a Swan type structure, and the inward flange 23 at the lower end of the cover 19 is caught by the flange 21, so that the cover is closed. 1
9 is prevented from coming off. The cover 19 is first fitted onto the outer periphery of the cylinder 7 with the short cylinder 22 not yet attached to the cylinder 7, and then the short cylinder 22 is fitted.

According to the above configuration, to install the lighting equipment,
As shown in the two-dot chain line in FIG. 1 or as shown in FIG.
Connect it to the rosette 14 by holding it by hand. Then, when the cover 19 is pushed upward, the spring wire 1
The cover 19 rises due to the upward biasing force applied in step 5, and the cover 19 comes to almost touch the ceiling 13.
It covers a ceiling mounting part consisting of a hook plug 12 and a rosette 14.

Note that at the middle height of the cover 19, the spring wire 15
Since the drag force toward the outside acts most on the cover 1
9 is below that height, the cover 19 is difficult to rise, and the cover 19 can be set to remain at the lower end position, and there is no need to hold down the cover 19 when connecting the hook plug 12 to the rosette 14, making installation easier. It's very convenient.

Effects of the invention As detailed above, according to the invention, the upward biasing force of the cover that covers the ceiling-mounted part of the lighting fixture can be extremely simplified by attaching only the base and end of the spring wire to the main body and cover, respectively. This has the effect of being able to be added at low cost. In addition, since the spring wire is easy to bend, the cover can be moved smoothly and the lighting equipment can be installed easily.
