Abstract

(57) [Summary] [Purpose] To facilitate construction and reduce construction man-hours. [Structure] Spring holders 12 on which springs 17 are locked are formed on both side pieces of the fixture 6. Anchor bolts are inserted through the holes 13 of the fixture 6 to fix the fixture 6 to the ceiling surface. A substantially U-shaped slide member 16 is slidably fitted in a slit 15 formed in the instrument body 11, and a substantially V-shaped spring 17 is loosely fitted in the slide member 16. Therefore, spring 1
7 is slidable via the slide member 16. Construction is completed by attaching the fixture 6 to the anchor bolt and attaching the instrument body 11 via the spring 17.
Therefore, the number of construction steps can be reduced. Further, since the spring 17 is slidable, even if the attachment pitch of the fixture 6 is deviated, the attachment error of the fixture 6 can be absorbed and the instrument body 11 can be easily attached to the fixture 6.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an embedded lighting fixture installed in an opening or the like on a ceiling surface.

[0002]

[Prior art]

 FIG. 4 is a perspective view of a conventional ceiling-mounted lighting fixture, and FIG. 5 is an exploded perspective view thereof. Sockets 3 for mounting the lamps 4 are provided on both sides of the lower surface of the fixture body 1 in which a lighting device such as a ballast 2 is arranged. A fixture 6 is attached to the lower surface of the instrument body 1.

A reflector 5 is arranged on the lower surface of the instrument body 1, and a lamp 4 is arranged inside the reflector 5. The reflection plate 5 is fixed to the instrument body 1 by a substantially U-shaped metal fixture 6 and a knob 7. That is, the reflection plate 5 is formed with a long hole-shaped hole 8 through which the knob screw 7 is inserted. The reflector 5 is attached to the instrument body 1.

As a construction procedure of such a conventional example, the instrument body 1 is attached to the anchor bolt suspended on the back surface of the ceiling, and the reflector plate 5 is attached with the knob screw 7. Then, the lamp 4 is attached.

[0005]

[Problems to be solved by the device]

 In such a conventional example, the construction procedure was required three times as described above. Further, the mounting pitch of the fixture 6 to the instrument body 1 is determined, and in consideration of workability when mounting the reflection plate 5, the hole 8 of the reflection plate 5 through which the knob screw 7 is inserted is formed in a long hole shape. There is. Therefore, in order to hide the play of the hole 8, a locking means having a cover larger than the shape of the hole 8 such as a thumb screw 7 and a latch is required. Moreover, when the pitch of the anchor bolt was slightly misaligned, the construction became difficult and difficult.

The present invention has been made in view of the above-mentioned points, and provides a lighting fixture for the purpose of facilitating construction and reducing the number of construction steps.

[0007]

[Means for Solving the Problems]

 The present invention is provided with a fixture arranged on the ceiling surface and a fixture body mounted on the fixture and integrally configured with a lighting device, a reflection plate, etc., and the fixture body can be slid with respect to the fixture. It is provided with various means.

[0008]

[Action]

 Thus, by arranging the fixture on the ceiling surface and attaching the instrument body to the fixture via slidable means, the number of construction steps can be reduced, and the instrument body can be attached to the fixture. By making it slidable, construction can be facilitated even if the mounting pitch of the fixture is slightly displaced.

[0009]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the instrument main body 11 is configured by integrating a ballast, a reflection plate 5 and the like, and is characterized in that the instrument main body 11 and the fixture 6 are divided into two parts. That is, the spring receivers 12 are formed by cutting and inwardly on the side pieces on both sides of the substantially U-shaped fixing tool 6, and a substantially hole-shaped hole 13 is formed at the substantially central portion of the fixing tool 6. is there. Anchor bolts suspended on the back surface of the ceiling are inserted into the holes 13 of the fixture 6 to fix the fixture 6 to the ceiling surface.

Further, as shown in FIG. 2, notches 14 are formed on both sides of the instrument body 11 on the end side, and a slit 15 is provided below the notches 14 in the lateral direction, that is, the device. It is formed in the longitudinal direction of the main body 11. A substantially U-shaped sliding member 16 is slidably fitted in the slit 15 and a substantially V-shaped spring 17 is loosely fitted in the sliding member 16. Therefore, the spring 17 is slidable via the slide member 16.

The construction of the lighting fixture can be completed by attaching the fixture 6 to the anchor bolt and attaching the main body 11 of the fixture via the spring 17. Therefore, the number of construction steps can be reduced as compared with the conventional one. can do. By hooking and locking the tip of the spring 17 on the spring receiver 12 of the fixture 6, the instrument body 11 is mounted on the fixture 6. Since the spring 17 is slidable, even if the mounting pitch of the fixture 6 is deviated, the spring 17 can be slid to absorb the mounting error of the fixture 6 as shown by the arrow in FIG. The body 11 can be easily attached to the fixture 6. Moreover, since the reflector body 5 and the lighting device are integrated into the instrument body 11, the instrument body 11 can be made thin.

Further, as shown in FIG. 3, a box 19 having a built-in ballast 2 and a terminal block 18 connected to a power supply line can be slid on the upper surface of the appliance body 11 to avoid a ceiling structural member. It is configured like this. That is, as shown in FIG. 3, a slit 20 is formed on the upper surface of the instrument body 11 in the longitudinal direction, and a projection (not shown) to be inserted into this slit 20 is provided on the lower surface of the box 19 so that the box 19 is opened. It is configured to be slidable in the longitudinal direction.

Therefore, by sliding the box 19, it is possible to fix the box 19 to the instrument body 11 while avoiding the ceiling structure member.

[0014]

[Effect of device]

 As described above, the present invention includes the fixture arranged on the ceiling surface and the fixture main body attached to the fixture and integrally configured with the lighting device, the reflection plate, etc. Since it is provided with a slidable means, the fixture can be arranged on the ceiling surface, and the fixture main body can be attached to this fixture via the slidable means to reduce the construction man-hours and also the fixture. By making the main body slidable with respect to the fixture, the construction can be easily performed even if the attachment pitch of the fixture is slightly deviated.
