Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling-embedded illuminating device, and more particularly to an illuminating device having an improved support structure for a luminaire main body.

[0002]

2. Description of the Related Art For example, in a ceiling-embedded fluorescent lamp fixture or the like, both sides of a lighting fixture body including a lamp socket and a reflector are supported in the ceiling through a pair of parallel support frames. It

In the ceiling of the building, for example, a pair of parallel ceiling bars are installed in an arrangement corresponding to the support frame,
The support frame is supported at both ends in the longitudinal direction by the brackets fixed to the ceiling bars.

By the way, when installing a lighting device, it is often the case that the main body of the lighting fixture is positioned and inserted and fixed in a mounting hole formed in a ceiling in advance. Therefore, usually, a positioning and fixing means for positioning and fixing each supporting frame with respect to each bracket along the longitudinal direction and the vertical direction is provided.

Positioning and fixing means for positioning and fixing the support frame along the longitudinal direction are, for example, for positioning and fixing when the horizontal position of the lighting fixture main body is changed or finely adjusted or the type of the fixture is changed. In the past, screws or the like have been used. That is, drill holes in the support frame and bracket,
At the time of installation, the frame is moved and adjusted in the longitudinal direction, and screws are screwed into the matching screw holes to perform positioning and fixing.

Further, the positioning / fixing means for positioning and fixing in the vertical direction is applied to, for example, a structure capable of selectively mounting an accessory such as a louver below the lamp. That is, at the time of attaching the accessory, it is necessary to install the lighting fixture main body at a high position in order to form an accessory mounting space below the lamp. In this case, the bracket supports the support frame at the high position. Further, since the space is not needed when the accessory is not used, the lighting fixture main body is installed at a low position, and in this case, the support frame is supported by the bracket at the low position.

As the positioning and fixing means along the vertical direction of such a supporting frame, a locking member such as a screw or a spring is conventionally used. That is, the bracket is configured to be expandable / contractible by two vertically slidable members, and screw holes or locking holes are formed at the positions of the two members that match at appropriate expansion / contraction positions. A locking member such as a screw or a spring is inserted into and locked.

[0008]

However, in the conventional structure using the above-mentioned positioning and fixing means, since a locking member such as a screw or a spring is used, the number of parts is large and the handling is complicated, and the positioning and fixing work is difficult. It takes a relatively troublesome task. Especially when screw holes etc. are provided in multiple places and screws are selectively screwed, it may be a work at a high place and the screw holes for positioning etc. may not be visible, and screwing may be done by groping, Construction efficiency tends to decrease.

The present invention has been made in view of the above circumstances, and an independent member such as a screw or a spring can be omitted for positioning and fixing the main body of the luminaire via the support frame, thereby reducing the number of parts. An object of the present invention is to provide a lighting device that can be easily handled, can be positioned and fixed easily and reliably, and can greatly improve work efficiency.

[0010]

In order to achieve the above-mentioned object, the invention of claim 1 is to provide a ceiling-mounted luminaire main body and a pair of parallel mutually supporting both side portions of the luminaire main body. A support frame, a bracket that is fixed in the building ceiling and supports each of the support frames,
In a lighting device provided with a positioning and fixing means for positioning and fixing each of the support frames with respect to each of the brackets in the longitudinal direction, the support frame and the bracket can slide with respect to each other via at least one pair of joint surfaces. And the positioning and fixing means includes a convex portion formed on a joint surface of one of the support frame and the bracket and a concave portion formed on the other joint surface and into which the convex portion is elastically fitted. It is characterized by being composed by and.

According to a second aspect of the present invention, a luminaire main body for burying a ceiling, a pair of parallel support frames for supporting both side portions of the luminaire main body, and a pair of support frames provided in the ceiling of the building are provided. In a lighting device including brackets that respectively support the support frames, and fixing means for performing positioning and fixing of the support frames in the up-down direction with respect to the brackets, each of the brackets is an element for fixing in the ceiling, 1 for this fixing element
It has a support frame mounting element held slidably in the vertical direction via the above-mentioned joint surface, and the positioning and fixing means is an elastic locking portion projecting from one of the joint surfaces of each element. And a locking hole formed in the other joint surface and into which the elastic locking portion is inserted and locked.

[0012]

According to the first aspect of the present invention, the support frame that supports the main body of the lighting fixture is slid with respect to the bracket along the longitudinal direction of the support frame with a force of a certain level or more, so that the projection and the recess are formed. It is possible to position and fix at a predetermined stop position by the elastic fitting of.

Therefore, a screw or the like, which has been conventionally used as an independent member for lateral positioning and fixing, is unnecessary,
As a result, the number of parts can be reduced, and since it is not necessary to use a tool such as a screwdriver at the time of construction, the handling can be simplified. In addition, the positioning and fixing to a predetermined position is automatically performed by elastically fitting the convex portion and the concave portion by simply sliding the supporting frame in the lateral direction, so that the positioning portion can be visually recognized when working at a high place. Even if it is difficult to do, the work can be performed easily and surely, and the work efficiency can be greatly improved.

According to the second aspect of the present invention, the support frame mounting element is slid vertically with respect to the fixing element forming the bracket, and the elastic lock forming the positioning fixing means at the predetermined height position. By inserting and locking the portion into the locking hole, the lighting fixture main body can be positioned and fixed at a predetermined height.

Therefore, for example, in a lighting device having a structure in which an accessory such as a louver can be selectively attached below the lamp, if a plurality of elastic locking portions or locking holes are provided, the lamp height can be adjusted. In such a case, the conventionally used independent members such as screws and springs are unnecessary, which reduces the number of parts and eliminates the need to use tools such as a screwdriver during construction, which simplifies handling. You will be able to plan.

Further, since the positioning and fixing to the predetermined position can be performed by the vertical sliding movement of the support frame mounting element and the elastic insertion and removal of the elastic locking portion into and from the locking hole, the positioning portion can be operated at a high place. Even if it is difficult to see, the work can be performed easily and surely, and the work efficiency can be greatly improved.
