Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a mounting device for a lighting fixture, particularly suitable as an insect-proof type.

Conventionally, in order to prevent insects from entering the fixture body through the mounting hole, the conventional lighting fixture has a fixture body 1 as shown in FIG.
If the main body 1 becomes large and heavy, it becomes difficult to install it, so as an improved method, for example, use auxiliary metal fittings 3 as shown in Figs. 2 and 3. First, fix this to the surface A with wood screws 2, and then attach the main body 1 to the auxiliary metal fitting 3 using the threaded rod 4 set on the auxiliary metal fitting 3 and the wing nut 5 screwed thereto. I was trying to fix it.

However, with these mounting means, when fixing the instrument body 1, first determine the fixing position of the instrument body, and then use wood screws 2 etc. to fix the instrument body 1 at a predetermined position on surface A. It is necessary to prevent the device from falling, and this makes it extremely difficult for one person to attach this type of device to a ceiling or the like.

This invention takes these points into consideration and relates to a lighting equipment mounting device that further improves the workability of the installation and the later insect-proofing effect, etc. One embodiment of this invention will be described below.

That is, the fourth. In Figure 5, 1. The same parts as those in Fig. 2 are indicated by the same symbols, but in the case of this device, as shown in Fig. 4, the auxiliary bracket 3 has four threaded rods 4 planted on its lower surface, and The wing nuts 5 are screwed into each other, and the main body 1 of the instrument is provided with four daruma holes B corresponding to the threaded rods 4 of the auxiliary fitting 3, and each of these daruma holes The inner diameter of the circular hole 6 of the hole B is larger than the outer diameter of the wing nut 5, and the width of the circular hole 6 and the series of slits 7 is slightly larger than the outer diameter of the threaded rod 4. are doing.

The insect-proof washer 8 shown in the figure is prepared for sealing the Daruma hole B, and this washer has a circular convex portion 9 to be fitted into the circular hole 6 of the Daruma hole B, and a threaded rod 4 at the tip thereof. A notch 10 is provided for passage.

In the above configuration, the attachment of the instrument main body in the case of this invention is performed in the following order.

(I) When installing the auxiliary metal fitting 3 to a ceiling or the like, fix it to the surface A with wood screws 2.

(II) Thread the wing nut 5 onto the tip of each threaded rod 4.

(III) As shown in FIG. 5A, the wing nut 5 is passed through the circular hole 6 of the daruma hole B of the instrument body 1, and the instrument body 1 is temporarily fixed at the position of the slit 7 as shown in the opening in the figure.

(IV) As shown in FIG. The part 6 and the circular convex part 9 of the washer 8 are fitted together, and in this state, the wing nut 5 is tightened to fix the instrument main body 1 together with the insect-proof washer 8 to the auxiliary metal fitting 3.

Since this device is constructed as described above, the main body 1 of the device can be temporarily fixed in the state of the opening shown in FIG. The circular convex part 9 of the washer 8 and the circular hole part 6 of the Daruma hole B are fitted to prevent the instrument body 1 from shifting in the lateral direction with respect to the threaded rod 4. This has the advantage that the instrument main body 1 can be reliably fixed in a predetermined position with the above-mentioned simple wing nut.

First of all. In FIG. 2, 11 indicates a main body cover, and 12 indicates an internal lamp thereof.

[Brief explanation of drawings]

Figures 1 and 2 are sectional views of the conventional product, Figure 3 is an exploded perspective view of the main parts of Figure 2, Figure 4 is an exploded perspective view of the main parts of this invention, and Figure 5 is the same. The installation is an explanatory diagram of the order. In the figure, 1 is the main body of the instrument, 3 is an auxiliary fitting for hanging this main body, 4 is a threaded rod installed on this, 5 is a wing nut screwed onto this threaded rod, and B is a circular hole 6. 8 is an insect-proof washer, 9 is a circular convex portion formed on this washer, 10 is a notch at its tip, and A is a surface to which it is attached. In other figures, the same reference numerals indicate the same or corresponding parts.

Claims (2)

[Scope of utility model registration request] (1) The auxiliary metal fitting 3 is fixed to the surface A, the slit part 7 through which the threaded rod 4 installed on the auxiliary metal fitting is passed, and the circular hole 6 through which the wing nut 5 screwed onto this screw rod is passed. The instrument body 1 has a Daruma hole B made of An insect-proof washer 8 is attached, which has a notch 10 that engages with the threaded rod 4 when the auxiliary fitting 3 and the instrument main body are fully connected, and which seals the circular hole 6 of the Daruma hole B. A lighting equipment mounting device characterized by: (2) Each insect-proof washer 8 has a hole B provided in the device body 1.
The first utility model registration claim has a positioning circular convex portion 9 that is inserted into the circular hole portion 6 of the device so as to seal the iron portion and prevents the device body 1 from returning after installation is completed. Lighting equipment mounting device as described in section.
