[Industrial applications]

 The present invention relates to improvement of the mountability of a ceiling-mounted lighting fixture to the ceiling surface.

[0002]

[Prior Art]

 This type of ceiling-mounted lighting fixture is used by mounting the main body of the fixture on the ceiling surface, and is used recently for houses with a low ceiling surface and for lighting fixtures for multiple lights that are heavy and cannot be hung with a cord. Is being done.

By the way, in addition to the above ceiling-mounted type, the mainstream of this kind of general household lighting fixtures is a cord hanging type, and it is usually easy to attach these fixtures to the indoor wiring of a house. In addition, a hook ceiling body is arranged on the ceiling surface. In the case of a cord hanging type lighting fixture, a hook hook sealing cap that has a conductive hook metal fitting at the tip of the power cord and is mechanically and electrically hooked to the hook ceiling body is attached. It is constructed so that it can be easily installed.

On the other hand, in the case of a ceiling-mounted light fixture, the fixture body may be screwed directly to the ceiling surface, but the weight of the fixture is heavy for a few minutes, and construction on a high ceiling surface is difficult. Simple fittings are usually used. In other words, in a ceiling-mounted lighting fixture, the hook ceiling body fixed to the ceiling surface is exposed below the fixture body from the opening formed in the approximate center of the fixture body, and the upper surface of the fixture body is placed facing the ceiling surface. The fixture is attached directly to the ceiling surface.To attach the fixture body to the ceiling surface, first attach a simple mounting bracket around the hook ceiling body and attach it to the ceiling surface using the mounting screws. It is designed such that the dharma hole provided on the instrument body is hooked and temporarily held to perform the mounting operation.

As described above, since the ceiling-mounted lighting fixture uses the simple mounting bracket, it is not necessary to fix the heavy fixture main body to the ceiling surface with screws, and the mounting work becomes considerably easy. It was a thing. However, since the ceiling surface is generally high and a scaffold is required, it is difficult to screw on the ceiling surface even with a simple mounting bracket that is light in weight, and it is not comparable to the mountability of a cord hanging luminaire. Met. Especially, when the ceiling surface is concrete, it is difficult for an amateur to screw the work itself, and there has been a demand for improvement in workability of mounting the direct lighting fixture for the ceiling on the ceiling surface.

Therefore, as disclosed in Japanese Utility Model Application Laid-Open No. 62-54414, the applicant of the present invention directly attaches to the ceiling with a structure in which a lighting fixture is supported by a hook ceiling cap connected and locked to a hook ceiling body. Developed and studied lighting equipment. That is, as shown in FIG. 3, in this lighting device 1 directly attached to the ceiling, the lighting device main body 3 which is installed in opposition to the surface of the ceiling 2 has a hook ceiling body 4 which is substantially in the center of the lighting device main body 3 as in the conventional case. Is inserted and an opening 5 is provided to expose it downward. In addition, on the lower surface side of the fixture body 3, lighting circuit components 6 such as a ballast, a lamp socket 7, a fluorescent lamp 8 mounted on the lamp socket 7, and these are covered from below to cover the periphery of the fixture body 3. A locked translucent cover 9 is mounted. This lighting fixture 1 is characterized in that a hook ceiling cap 11 having lock portions 10 for supporting the main body 3 of the fixture is attached to the lower surface side of the hook ceiling body 4, and the lock portion 10 is attached to the hook ceiling cap 4. A body support member 12 that supports the instrument body 3 is attached.

[0007]

[Problems to be solved by the device]

 The ceiling-mounted light fixture 1 having the above structure is configured so that the fixture body 3 is supported by the hook ceiling cap 11, and does not use a simple mounting metal fitting unlike the conventional ceiling-mounted lighting fixture. No screwing work to the surface is required, and the installation operation is extremely easy, and one-touch installation work is performed. However, the main body supporting member 12 disclosed in Japanese Utility Model Laid-Open No. 62-54414 is such that a fixing member is simply interposed between the instrument main body 3 and the locking portion 10 of the hook sealing cap 11, or the main body supporting member. 12 is integrally formed on the peripheral surface of the hook sealing cap 11, and it is difficult to perform the attachment operation of the instrument body 3, and the contact portion of the lower surface of the instrument body 3 with the body support member 12 is damaged. There was a problem.

Therefore, the present invention has been made in view of the above, and an object thereof is to obtain a support structure for an instrument main body that is easy to attach and does not cause scratches or the like on the lower surface of the instrument body.

[0009]

[Means for Solving the Problems]

 For this reason, the present invention exposes the hooking sealing body fixed to the ceiling surface to the lower side of the instrument body from the opening formed in the substantially central part of the instrument body so that the upper side of the instrument body is opposed to the ceiling surface. In the lighting fixture directly attached to the ceiling, in which the hook ceiling cap is locked to the lower surface side of the exposed hook ceiling body, and the main body of the fixture is attached to the ceiling surface through the hook ceiling cap, the hook ceiling cap is a side surface. A hook locking plate is disposed in the portion, and the instrument body has a locking portion at the periphery of the opening, a locking portion at the front end that is constantly locked by a spring on the hook locking plate, and a rear end at the locking portion. The locking handle is pivotally mounted and fixed so as to be rotatable from the opening to the lower surface and has an operating portion for releasing the hook locking.

[0010]

[Action]

 In the ceiling-mounted lighting fixture having the above-mentioned configuration, in the main body of the fixture, the locking portion at the end of the locking handle is always locked by the spring to the locking plate on the side surface of the hooking ceiling cap, and is stably supported. In addition, when mounting or removing the instrument body, the instrument body can be freely moved up and down by operating the locking handle on the lower surface of the opening to release the locking of the hook locking portion, and it can be easily attached and detached.
