Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hanging ceiling to which a hook blade can be connected.

[0002]

2. Description of the Related Art There has been conventionally provided a hooking ceiling which is attached to a construction surface such as a ceiling surface and has a hooking blade receiving portion for connecting a hooking blade provided on a lighting fixture.

[0003] In recent years, there has been provided a lighting fixture which is mounted near a ceiling surface, and this kind of lighting fixture is easy to obtain a design which can be used without feeling uncomfortable regardless of a Western-style room or a Japanese-style room. It has the advantages that it can be mounted and replaced by the user himself, and that a structure that is difficult for insects to enter can be easily realized.

Various types of structures for attaching this type of lighting fixture to a hooking ceiling have been proposed. The simplest structure is to provide a hooking plug connected to a catching blade receiving portion of a hooking ceiling in a lighting fixture, and to provide a hooking plug. In some cases, the hooking ceiling and the lighting fixture are mechanically connected only by the connection between the blade and the hooking blade receiving portion.

However, in this configuration, the mechanical connection between the hooking ceiling and the lighting fixture is limited to only two places near the center of the hooking ceiling, and a large lighting fixture tends to wobble and cannot be fixed sufficiently. There is. Further, since the load of the lighting fixture is supported only by the catching blade receiving portion, it cannot be applied to a lighting fixture having a relatively large weight. Even if the weight is relatively small,
If the weight of the luminaire is supported only by the catch blade receiving portion, the catch blade receiving portion may be deformed over time, which may lead to poor contact.

On the other hand, in the configuration shown in FIG. 48 described in JP-A-7-37417, an adapter 3 is provided between the hooking ceiling 1 and the lighting fixture 2. That is, in this configuration, as shown in FIG. 49, the hooking blade 4 projecting from the adapter 3 is mechanically and electrically coupled to the hooking ceiling 1, and the locking step 5 formed on the outer peripheral surface of the adapter 3 is formed.
, The slide member 9 provided on the lighting fixture 2 is engaged. The electrical connection between the lighting fixture 2 and the hanging ceiling 1 is made via a connection line 7 provided on the adapter 3. Therefore, by connecting the lighting fixture 2 to the outer periphery of the adapter 3, the area of the fixing portion of the lighting fixture 2 can be increased, and the wobbling of the lighting fixture 2 can be prevented.

However, even in this configuration, the load of the lighting fixture is supported only by the catching blade receiving portion, and according to the Electrical Appliance and Material Control Law, a load exceeding 5 kg must be prevented from being applied to the electrical connection portion. However, it cannot be applied to the lighting fixture 2 having a relatively large weight.
Further, there is a possibility that the catching blade receiving portion may change over time. In addition, since the work of attaching the adapter 3 to the hooking ceiling 1 is required, the attaching work is troublesome. Further, between the hooking ceiling 1 and the lighting fixture 2, there are two connecting points, that is, a connection between the hooking ceiling 1 and the adapter 3 and a connection between the adapter 3 and the lighting fixture 2. However, if the connection state is incomplete, there is a risk of the lighting fixture 2 dropping, and further attention is required to ensure safety as compared with the case where the adapter 3 is not provided. In addition, since the adapter 3 must be sold together with the lighting equipment 2 as a product, the lighting equipment 2
Sales prices will rise. In addition, the presence of the adapter 3 between the hooking ceiling 1 and the lighting fixture 2 increases the size of the projection of the lighting fixture 2 from the ceiling surface. In particular, in the lighting fixture 2 using a straight tube lamp, the lamp cannot be arranged in the same plane as the adapter 3, so it is difficult to reduce the projection size of the lighting fixture 2 from the ceiling surface.

Japanese Patent Application Laid-Open No. 6-267322 discloses a hanging ceiling 1 which can be applied to a lighting fixture having a relatively large weight, as shown in FIG. Has been described.
In this configuration, the slide member 9 provided on the lighting fixture 2 is engaged with the mounting bracket 8 provided on the hooking ceiling 1, and the lighting fixture 2 is connected at the periphery of the hooking ceiling 1. The lighting fixture 2 can be supported without shaking, and the load of the lighting fixture 2 is received by the mounting bracket 8, so that the lighting fixture 2 can be applied to the lighting fixture 2 having a relatively large weight. In addition, since an adapter is not required in this configuration, installation work is reduced.

[0009]

However, in the above-described structure, the lighting fixture 2 having a large weight cannot be attached unless the mounting bracket 8 is provided on the hanging ceiling 1, so that the component cost of the hanging ceiling 1 increases. .

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a hook-type ceiling which allows a relatively large weight of a lighting fixture to be mounted, but does not increase the number of parts. It is in.
