BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover that requires opening and closing of a lighting fixture.

[0002]

2. Description of the Related Art A conventional spotlight cover opening / closing mechanism has vertical legs 6a, 7a at both ends of a mounting portion 5a provided at one end of a cover as shown in FIG.
Has guide pieces 8a and 9a at the end of the main body 2a to facilitate entry into the square hole 4a, and has a guide piece at the end of the guide pieces 8a and 9a with locking pieces 10a and 11a in consideration of a return guide and retaining. Into the square hole 4a of the main body 2a,
The cover 1a is fixed to the main body 2a by the contact between the locking pieces 10a and 11a of the leaf spring and the end face of the square hole 4a of the main body 2a.

[0003]

The above-described conventional spotlight cover opening / closing mechanism can open and close the cover 1a with one touch, but the cover-1a vibrates due to an external impact, and the leaf spring 5a fixed to the cover-1a. Locking piece 10
There has been a problem that a and 11a are easily moved inward by the square hole 4a of the main body 2a and easily come off. The cover 1a and the main body 2a
If the fitting position is deviated, there is a problem that the leaf spring 5a on the side of the main body 2a that is displaced outside the square hole 4a is largely bent and deformed when the cover-1a is opened. Further, there is a problem that light leaks from a gap between the square hole 4a of the main body 2a and the leaf spring 5a. The present invention has been made in view of such a point, and the purpose thereof is to open and close the cover 1a by a simple operation, the cover 1a is not opened by an external impact, and light is transmitted from the square hole 4a of the main body 2a. An object of the present invention is to provide a spotlight cover opening / closing mechanism that does not leak and that facilitates dimensional control of component parts.

[0004]

A cover provided on a cover is provided.
A lock fitting that slides on the mating surface of the cover to fix the cover to the main body, a cover handle connected to the lock fitting with the cover interposed therebetween, and a main body provided on the main body side mating surface and engaging with the lock fitting. A spotlight cover opening / closing mechanism comprising a side fixing portion, wherein the lock fitting has a stepped flat plate-shaped sliding portion and a rising portion connected to a slidable handle on the outer surface of the cover, and the main body side fixing portion. An opening for inserting a tongue at one end of the slide portion of the lock fitting provided on the cover side and a tongue at one end of the slide portion located at the bottom of the opening are pressed against the back surface of the mating surface of the main body. It has a leaf spring, and inserts the tongue piece at one end of the slide part of the lock fitting into the opening of the main body and slides the handle, so that the tongue piece at one end of the slide part of the lock fitting is connected to the back surface of the mating surface of the main body. Board Ne by holding between the cover - to solve the problem described above by the fixing to the body.

[0005]

With the above construction, even when there is an external impact, the cover cannot be easily opened because the tongue of the cover lock is held between the back surface of the mating surface of the main body and the leaf spring. Further, since the leaf spring shields the opening of the fixing portion on the main body side, light does not leak from the opening.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1, 2 and 3. FIG. The spotlight cover opening and closing mechanism is
A lock 7 provided on the cover 1 for sliding along the mating surface of the cover 1 and the main body 2 to fix the cover 1 to the main body 2, and a cover connected to the lock 7 with the cover interposed therebetween. It comprises a handle and a main body side fixing portion provided on the mating surface of the main body 2 and engaging with the lock fitting 7.

As shown in FIG. 3, the lock fitting 7 has a rising portion 23 on a side surface of a stepped flat plate-shaped sliding portion 20.
Is fixed to the slide portion 12 of the handle 3 on the outer surface of the cover with the cover 1 interposed therebetween. The slide portion 20 has a stepped tongue piece 22 at one end, and a fitting hole 24 in the center of the tongue piece 22. Has,
The other end of the slide portion 20 has a fitting hole 21.

The main body fixing portion includes a square hole 4 into which a tongue piece 22 at one end of the slide portion 20 of the lock fitting 7 is inserted, and a tongue piece 22 of the slide portion 20 located at the bottom of the square hole 4. Plate-shaped leaf spring 5 that presses against
And a hole 2 provided in a tongue piece 22 at one end of a slide portion 20 of the lock fitting 7 at a slide end of the lock fitting 7.
4 is fitted to the back surface 11 of the mating surface.
. Cover-1 is the back side 1 of the mating surface
0, a square hole 6 into which the tongue piece 22 of the lock fitting 7 is inserted.
And a projection 8 which fits into a hole 21 provided at the end of the slide portion 20 of the lock fitting 7 at the slide end of the lock fitting 7, and has a slide portion of the cover handle 3 on a side surface perpendicular to the mating surface 10. It has twelve sliding holes.

In the assembled state, the handle 3 provided on the side surface of the cover 1 and having the hole 21 of the lock fitting 7 and the projection 8 of the cover 1 fitted to each other is rotated toward the main body, and the lock fitting 7 is rotated. Is inserted into the square hole 4 of the main body 2, and when the mating surface of the cover 1 and the mating surface of the main body come into contact with each other, the cover handle 3 is slid so that the tongue 22 of the lock fitting 7 is attached to the main body 2. It is held between the back surface 11 of the mating surface and the leaf spring 5, and the protrusion 9 of the main body 2 is
The cover 1 is fixed to the main body 2 by fitting.

[0010]

In the spotlight cover opening / closing mechanism according to the first aspect, since the cover-1 and the main body 2 are fixed by the lock metal 7, the cover cannot be opened by an external impact. When the cover 1 is closed, the leaf spring 5 fixed to the main body 2 receives the tongue piece 22 of the lock fitting 7, so that the impact caused by the collision between the lower end surface of the cover 1 and the lower end surface of the main body 2 is absorbed. Also, since the leaf spring 5 has a larger space than the square hole 4, the square hole 4
Prevent light leakage from In the spotlight cover opening / closing mechanism according to the second aspect, the resistance of fitting between the projections 8 and 9 provided on the back surface of the mating surface of the cover and the main body and the holes 21 and 22 of the lock fitting 7 changes when the lock is attached and detached. Therefore, the user can judge whether the lock is attached or detached by touch. Further, since the hole 21 of the lock fitting 7 is fitted to the projection 8 of the cover 1 in a state where the lock fitting 7 is removed from the fixing portion on the main body side, the lock fitting 7 does not shift.
