Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a ceiling-embedded lighting fixture that can be integrated with an air duct of an air conditioner.

PRIOR ART

In so-called system ceilings and modular ceilings,
A device that combines the air duct of an air conditioner and a lighting fixture has been put into practical use. Such ceiling devices systemize buildings such as houses, emphasize the functions of air conditioners and lighting equipment, and rationalize the structure of the building itself. In particular, when the air duct of an air conditioner and a lighting fixture are integrated, each of the fixtures, which were originally configured individually, are combined in the ceiling, making the ceiling smaller and moreover, increasing the space inside the room. It has the advantage of being highly decorative.

[The problem that the idea aims to solve]

By the way, combining the air duct of an air conditioner and lighting equipment is not limited to system ceilings or modular ceilings, but also in houses where air ducts and lighting equipment were installed independently. There is a demand for systematization.

However, in these types of houses, even in the case of new construction, it is common for the lighting equipment to be installed by different contractors and the air conditioner to be installed by different contractors, or even if the two are the same, the installation process for each is different. It is true. That is, piping for the air conditioner is installed in the ceiling at the completion stage of the construction process, and lighting equipment is installed after the ceiling is completed.

The lighting fixture is then attached to the mounting window opened in the ceiling plate from below the ceiling plate. In that case, the worker must work by putting his/her upper body into the ceiling through the opening of the lighting fixture body attached to the ceiling board, and at that time, illuminate the air duct left near the mounting window. It is necessary to pull it toward the fixture body and fix the lighting fixture body and air duct together.

Conventionally, the lighting equipment body and the air duct were fixed by forming screw holes in the ceiling using a drill etc.
A method of fixing using bolts, nuts, etc. is used.

Incidentally, such work for fixing the lighting equipment main body and the air duct is significantly different from work performed on the ground or the like where there is a large work space. In other words, workers have to work with half their bodies inside the ceiling, which is becoming increasingly narrow, and working conditions are poor, such as poor ventilation in the closed ceiling, making it difficult to work. There are also safety issues for workers, such as reduced efficiency and the risk of accidents such as oxygen deficiency.

Therefore, the object of this invention is to provide a lighting fixture that has a simplified structure for combining with an air duct and facilitates installation work.

[Means for solving the problems]

The lighting fixture of this invention includes a lighting fixture main body 4 that is attached from below to a mounting window 6 opened in a ceiling board 2, and an air duct 34 that is disposed within the ceiling board and performs ventilation from the ceiling board side. and the fixed pieces (brackets 44, 4) fixed to this air duct.
6), a locking protrusion (screws 48, 50) disposed on the fixing piece, and a locking protrusion formed on the lighting fixture body side corresponding to the locking protrusion into which the locking protrusion can be inserted. It includes locking holes 38, 40 consisting of a first opening 54a and a second opening 54b that locks the locking protrusion inserted through the first opening,
Insert the locking protrusion of the air duct from the first opening into the locking hole of the lighting fixture body attached to the mounting window, and lock it in the second opening, and The lighting equipment main body and the air duct are combined.

In the lighting fixture of this invention, the locking convex portion is a screw having a head 52 that can be inserted into the screw hole of the fixing piece through the first opening and is locked in the second opening. 50.

[Effect]

In the lighting equipment of this invention, the lighting equipment body is attached to the completed ceiling board from the bottom of the ceiling board, and the worker inserts the upper body into the ceiling through the lighting equipment body.
Pull the air duct left nearby towards the lighting fixture body. Then, align the locking protrusion of the fixing piece attached to the air duct with the first opening of the lighting equipment main body, insert it into the lighting equipment main body side, and pull it down using the air duct's own weight to The locking convex portion is pulled down and locked to the opening side of No.2. As a result, the lighting fixture body and the air duct are combined. Therefore, with such a so-called one-touch fixing structure, the lighting fixture body and the air duct can be easily combined, and the working time can be shortened.

In the lighting equipment of this invention, when the locking convex type is composed of a screw, the screw is fixed in a screw hole formed in advance on the fixed piece of the air duct, and the head of the fixed screw is By inserting it through the first opening and fixing it to the second opening, the lighting fixture main body and the air duct can be combined.
