Description

[Detailed Description of the Invention] This invention relates to a lighting fixture, and particularly relates to an improvement in the mounting portion of a frame that covers a glove holder.

2. Description of the Related Art Lighting equipment that is directly attached to a support such as a wall or ceiling using screws or the like is often used in, for example, entrance lights.

One of the requirements for such lighting equipment is ease of attachment to the support.

Another important point is that since it is often used as an outdoor light, the structure must be such that sufficient waterproof and insect repellent effects can be obtained even if there are variations in installation work.

By the way, this type of lighting equipment has a globe, a globe holder that fixes the globe by screwing it together, and a frame that covers the globe holder, and the globe holder is attached to a support such as a wall or ceiling with screws or the like. It is fixed to .

However, in conventional lighting equipment, the globe holder and frame are fixed in advance with screws or caulking, and then the globe holder is attached to the support.
When screwing the glove into the glove holder, a gap sometimes formed between the frame and the glove.

Furthermore, since the frame is fixed to the glove holder, there is a drawback that the direction in which the frame is attached to the support cannot be specified unless the attachment position of the glove holder to the support is constant.

The object of the invention is therefore to provide a luminaire which eliminates the above-mentioned drawbacks by means of a relatively simple construction.

Examples of this invention will be described above with reference to the drawings.

FIG. 1 is a schematic longitudinal cross-sectional view of a lighting fixture that is a first embodiment of this invention.

In the figure, 1 is an incandescent lamp, 2 is its socket, and 3 is an incandescent lamp.
is the power line fixing part.

Incidentally, although an incandescent lamp is used as the illumination lamp in this embodiment, it goes without saying that an illumination lamp equivalent to a fluorescent lamp may be used.

Reference numeral 4 denotes a globe, which is made of glass or plastic molded product, and has a threaded portion 4a formed on its upper part.

Further, reference numeral 5 denotes a glove holder, which has a threaded portion 5a formed at its lower part and is screwed into the threaded portion 4a of the glove 4, and this glove holder 5 is attached to the ceiling 7 with screws 6.

Reference numeral 8 denotes a frame that covers the glove holder 5, which is molded from wood or plastic, and has a protruding part 8a horizontally disposed at the lower part of the inner side of the frame, and the lower surface of this protruding part is the flat part 4b of the glove 4.
It is pressed into place.

Further, as shown in the figure, the length from the upper end of the frame 8 to the upper surface of the protrusion 8a is set longer than the height of the glove holder 5, and a gap is formed between the upper surface of the protrusion 8a and the lower end of the glove holder 5. I'm trying to make it happen.

Next, we will explain the work procedure for installing the lighting fixture with the above configuration.

First, the glove holder 5 is attached to the ceiling using screws 6.

As will be described later, there is no need to consider the mounting position of the glove holder relative to the ceiling 7 at this time, and the operator only needs to consider the position of the screw 6.

After the glove holder 5 is attached, the frame 8 and the glove 4 are attached next.

This installation involves placing the protruding part 8b of the frame 8 on the flat part 4b of the globe 4, and then screwing together the screw parts 4a and 5a until the frame 8 is clamped and fixed between the ceiling 7 and the flat part 4b. This is done by tightening.

In this case, as the glove 4 is screwed into the glove holder 5, the frame 8 and the ceiling 7, and the frame 8 and the glove 4
Since a strong adhesion force is generated between them, when the glove 4 is sufficiently tightened, the frame 8 and the ceiling and the frame 8 and the glove 4 can be completely brought into close contact.

In addition, at this stage of work, if the frame 8 has a rectangular shape and is about to be fixed in a fixed position without facing the prescribed direction, the frame 8 should be moved horizontally. The glove 4 is rotated to face in a predetermined direction, and the glove 4 is tightened.

The above operations complete the assembly of this lighting fixture.

Therefore, as is clear from the above description, there is no need to attach the frame 8 to the glove holder with screws or the like, and the only fixing screws required are the screws 6 for attaching to the ceiling 7.

As a result, the misalignment that inevitably occurs when fixing screws (due to the clearance of the screw holes) does not occur when installing the frame 8, and the upper end of the frame 8 is in close contact with the ceiling 7, and the lower part is in close contact with the flat part 4b of the glove 4, and from the appearance,
Unnatural gaps will no longer form.

Further, as described above, since the frame 8 can be freely rotated during the assembly operation, the mounting position of the glove holder 5 is not restricted to a specific position.

This is because even if the holder 5 is installed in a bad position, by rotating the frame 8, the desired relative position of the frame 8 with respect to the ceiling can be easily set.

Therefore, there is no need to tighten the screws 6 while keeping the relative position between the globe holder 5 and the ceiling 7 constant as in conventional lighting equipment, and work efficiency is significantly improved.

Further, since the frame 8 is clamped and fixed between the ceiling 7 and the glove 4, insect-proofing and waterproofing effects can be obtained at the contact portion with the ceiling and the glove.

FIG. 2 is a schematic vertical cross-sectional view of the main parts of a lighting fixture according to a second embodiment of this invention.

The difference in configuration from the above embodiment is that a decorative frame 9 is interposed between the frame and the globe.

Therefore, in the assembly work, the decorative frame 9 is placed on the flat part 4b of the glove 4, the frame 8 is further placed on the decorative frame 9, and the glove is tightened.

It goes without saying that in this embodiment as well, it is possible to improve workability and eliminate the occurrence of gaps in the same manner as in the above-mentioned embodiments.

FIG. 3 is a schematic longitudinal sectional view of the main parts of a lighting fixture according to a third embodiment of the invention.

The difference in configuration from the second embodiment is that the spring 10
Also, the frame 8 is temporarily fixed to the glove holder 5 by screws 11.

That is, after attaching the glove holder 5 to the ceiling 7, a spring 10 provided on a part of the holder 5 is used to lock the protrusion 8b formed inside the frame 8, and a screw 11 is further attached to the frame 8. The frame 8 is temporarily fastened by inserting the frame 8 into the screw hole and screwing it into the threaded part 5C of the glove holder 5 (do not fully tighten the screw 11), and then attach the decorative frame 9 to the flat part 4b.
, and tighten the glove 4.

After finishing tightening the glove, the screw 11 is tightened.

In this way, the glove may be tightened after temporarily fixing the frame using the spring and screw.

However, in this case, there are restrictions on the attachment position of the frame 8 to the glove holder 5, and only the decorative frame 9 is not subject to such restrictions.

In addition, in any of the above embodiments, the ceiling and the frame (including the decorative frame) are used.

Same below. ) and between the frame and the glove, it is possible to obtain waterproof and insect repellent effects.However, in order to obtain an even more waterproof effect, it is possible to eliminate the gaps between the frame and the glove. A waterproof gasket may be attached.

As explained above in the embodiments, according to this invention,
Due to its simple structure, it is very easy to install, and there is sufficient adhesion between the glove and the frame and between the frame and the support such as the ceiling so that no gaps are formed.Therefore, it has a good appearance, and is waterproof and insect-proof. We can provide lighting equipment with
