In addition, F is a socket for a lamp.

[0003]

[Problems to be solved by the device]

 However, in this luminaire, the attachment of the reflection shade D to the attachment metal fitting C is performed by using four decorative screws E, but one end of the reflection shade D is supported by one hand at a high place and the other end is supported. The mounting work is carried out in an unstable posture where the cosmetic screw E is screwed in by hand. For this reason, insertion of the decorative screw E from the hole D2 to the screw hole C3 is troublesome, and the decorative screw E can be fixed only by rotating it many times, so that an efficient mounting work cannot be performed. There's a problem.

Therefore, an object of the present invention is to provide a luminaire capable of efficiently mounting a reflection shade without complicating the mounting structure.

Therefore, in order to achieve the above-mentioned object, the present invention covers an instrument main body, a leaf spring extending from the instrument main body and having a hook portion at the tip, and covering the instrument main body. A substantially V-shaped reflector having an opening at a portion corresponding to the tip of the leaf spring is provided, and the hook portion of the leaf spring is hooked and locked on the edge of the opening of the reflector. A second invention of the present invention is characterized in that the leaf spring is fixed to the instrument body. A third invention is characterized in that a resin cover is attached to the leaf spring so as to cover the hook portion. According to a fourth invention, the cover is a substantially L-shaped main body portion that follows the leaf spring and the reflection shade, a cover portion that covers the hook portion of the leaf spring, and a protruding operation extending from the cover portion. It is characterized in that it is composed of parts. A fifth invention is characterized in that the cover is fixed to a leaf spring by heat welding a dowel provided on the main body. A sixth invention is characterized in that the cover is fixed to the leaf spring by a fixing means including a screw, a tack, an adhesive and ultrasonic welding. A seventh invention is characterized in that the hook portion of the leaf spring is formed in a substantially U-shape, and the edge of the opening of the reflection shade is inserted into the hook portion. Further, an eighth invention is that an instrument body, a leaf spring extending from the instrument body and having a hook portion at a tip thereof, an instrument body, and an opening at a portion corresponding to the tip portion of the leaf spring having a substantially V-shape. It is characterized in that it has a reflection shade in the form of a plate, forms an operating portion substantially at a right angle to the hooking portion at the tip end portion of the plate panel, and coats each surface with resin.

【Example】

 Next, an embodiment of the present invention will be described with reference to FIGS.

In the figure, reference numeral 1 is a ceiling surface, to which a U-shaped instrument body 2 is fixed. A leaf spring 3 formed in a substantially U shape is fixed to the instrument body 2 with screws, rivet caulking or the like. The leaf spring 3 is composed of, for example, a falling portion 4 having a hole 5 and a hooking portion 6 extending outward from the tip of the falling portion 4. The angles θ1 and θ2 formed by the respective members are set such that the angle θ1 is approximately 102 ° and the angle θ2 is approximately 110 °. On the other hand, for example, a resin cover 7 is attached to the leaf spring 3. The cover 7 is, for example, a main body portion 8 in which a first main body piece 8a and a second main body piece 8b are formed in a substantially L shape, and is integrally formed with the main body portion 8 and has a hook-shaped tip portion. The cover portion 9 has a locking portion 9a and an operating portion 10 integrally formed on the opposite side of the cover portion 9 in a protruding shape. A dowel 8c is integrally formed on the first body piece 8a and a reinforcing rib 8d is integrally formed on the second body piece 8b, and the dowel 8c is formed in the hole 5 of the falling portion 4. After inserting, it is welded with a trowel. A reflector 11 having a V-shaped cross section is arranged below the instrument body 2. Substantially rectangular openings 12 are formed on both sides of the reflection shade 11 at portions corresponding to the hooks 6. Incidentally, 13 is a lamp socket.

Next, a method of attaching the reflection shade 11 in this lighting equipment will be described. In the state shown in FIG. 1, the leaf spring 3 is displaced in the direction indicated by the arrow X in the figure by operating the operating portion 10 with a finger. Then, the reflection shade 11 is lifted up, and the cover portion 9 and the operating portion 10 of the cover 7 are inserted into the opening 12. Next, the leaf spring 3 is returned in the direction of the arrow Y in the drawing, and the corner portion 6a of the hook portion 6 is hooked on the edge of the opening. In this state, the reflection surface of the reflection shade 11 and the falling portion 4 of the leaf spring 3 are substantially at right angles to complete the attachment, and the opening 12 is closed by the second main body piece 8b. The locking portion 9a of the cover is tapered to some extent with respect to the reflection shade 11 in order to facilitate the return in the Y direction.

According to this structure, the reflection shade 11 can be attached by a simple operation of merely hooking the hooking portion 6 of the leaf spring 3 to the edge of the opening, so that the attachment work can be performed very efficiently. can do. Further, since the hook portion 6 of the leaf spring 3 is covered with the resin cover 7, there is a relationship that the slipperyness with respect to the reflection shade 11 is excellent, and therefore, the hooking operation of the hook portion 6 to the edge of the opening is performed. Can be performed smoothly, and damage to the reflective surface can be reduced. In particular, since the reflecting surface of the reflecting shade 11 and the falling portion 4 of the leaf spring 3 are configured to be at a substantially right angle, the end portion 11a of the reflecting shade 11 is in the ceiling when the reflecting shade 11 is supported. It surely abuts the surface 1. Furthermore, the opening 12 is closed by the second main body piece 8b, and the color of the second main body piece 8b is set to be almost the same color or the same color as the reflective shade 11. Therefore, it is possible to reduce deterioration of appearance characteristics.

FIG. 3 shows another embodiment of the present invention, in which the hook portion 31 of the leaf spring 3A is formed in a substantially U shape. The hook portion 31 is configured such that the first piece 31a and the second piece 31b face each other, and the opening 12 of the reflection shade 11 is at the same time when the opening 12 is disengaged from the second piece 31b. It returns in the Y direction by the spring force and is supported by the first piece 31a.

According to this configuration, the mountability can be improved as in the above-described embodiment, and the structure of the leaf spring can be simplified.

FIG. 4 shows a further different embodiment of the present invention, in which a leaf spring 3B has a hook portion 32 extending outward and a manipulating portion extending in the extension direction of the falling portion 4 at a front end portion thereof. 3 3 are formed. In particular, the hook portion 32 is formed by bending the central portion of the tip end portion as shown in the drawing, but it is also possible to bend both side portions as shown in the drawing. Further, the surfaces of the hook portion 32 and the operation portion 33 are thickly covered with a resin layer (protective layer) 34.

The present invention is not limited to the above-described embodiment. For example, the leaf spring may be formed in a U shape, or may be formed in an L shape so as to be fixed to the instrument body. The angle value of each part of the spring can be changed appropriately. Further, the cover can be fixed to the leaf spring by means of heat welding by means of dowels, or by means of screws, tacks, adhesives, ultrasonic welding or the like.

[0014]

[Effect of the device]

 As described above, according to the present invention, the reflection shade can be efficiently attached to the ceiling by a simple operation without using any decorative screws. In particular, by appropriately setting the angle of the leaf spring with respect to the reflection shade, the end portion of the reflection shade can be brought into close contact with the ceiling surface, and the aesthetics of mounting can be improved.
