Description

[Detailed description of the device]

[0001]

[Industrial application]

 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 for houses with a low ceiling surface and for lighting fixtures for multiple lights that are heavy and cannot be code-hung. It is being used frequently.

By the way, in addition to the above ceiling-mounted type, the mainstream of this type of general household lighting fixture is a cord hanging type, and these fixtures are usually attached to the indoor wiring of a house. For ease of use, a hooking sealing body is provided on the ceiling surface. In the case of a cord hanging type luminaire, a hook which is electrically connected to the hook ceiling body is provided with a conductive hook metal fitting at the tip of the power cord. A sealing cap is attached 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. That is, 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 center of the fixture body so that the top side of the fixture body faces the ceiling surface. Although it is configured so that it is installed opposite to and directly attached to the ceiling surface, first attach the simple mounting bracket to the ceiling surface around the hook ceiling body and screw it to this bracket. The attached mounting screw is used to hang the dharma hole provided in the main body of the device and temporarily hold it 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 onto the ceiling surface even with a simple mounting bracket that is light in weight. It didn't happen. In particular, 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 attaching the direct lighting fixture for the ceiling to the ceiling surface.

Therefore, as disclosed in Japanese Utility Model Laid-Open No. 62-54414, the present applicant has a structure in which a lighting fixture is supported by a hooking sealing ring cap connected and locked to the hooking sealing body. Developed and studied a ceiling-mounted lighting fixture. That is, as shown in FIG. 3, in this lighting device 1 directly attached to the ceiling, a device body 3 that is installed so as to be opposed to a ceiling 2 surface has a hooking seal ring at a substantially central portion of the device body 3 as in the conventional case. The body 4 is inserted and an opening 5 is provided to expose the body 4 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. The locked translucent cover 9 is mounted. This lighting fixture 1 is characterized in that a hooking sealing cap 11 is provided on the lower surface side of the hooking sealing body 4 for holding the lighting device body 3 on both sides, and the hooking sealing cap 11 is attached. A body support member 12 that supports the instrument body 3 is attached to the portion 10.

[0007]

[Problems to be solved by the device]

 The ceiling-mounted lighting fixture 1 having the above structure is configured to support the main body 3 of the fixture on the hooking sealing cap 11, and does not use a simple mounting metal fitting unlike the conventional ceiling-mounted lighting fixture. Since there is no need for any screwing work to the ceiling surface, the installation operation is extremely easy and the installation work can be done with a one-touch method. However, in the main body support member 12 disclosed in Japanese Utility Model Laid-Open No. 62-54414, a fixing member is simply interposed between the instrument main body 3 and the hook sealing ring cap 11 or the fixing member is hooked to the sealing ring. Since it is integrally formed on the side surface of the cap 11, the operation of attaching the instrument body 3 is difficult, and there are problems such as the occurrence of scratches or the like on the lower surface of the instrument body 3 in contact with the body support member 12. ..

Therefore, the present invention has been made in view of the above, and an object thereof is to obtain a structure of an instrument main body which is easy to attach and does not cause scratches or the like on the lower surface of the instrument main 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 surface side of the instrument body faces the ceiling surface. In the lighting fixture directly attached to the ceiling, the hook ceiling ring cap is installed on the lower surface side of the exposed hook ceiling body, and the fixture main body is supported by the hook ceiling cap. A locking groove is provided on the side surface of the sealing cap, and a claw box is arranged at a position facing the locking groove on the lower surface of the instrument body, and a locking claw that is locked in the locking groove inside the claw box. Is attached. Furthermore, the above-mentioned locking claw has a mating locking part with a slanted cross-section whose lower side gradually protrudes at the tip, and a locking release part bent rearward downward of the above-mentioned claw box. It is composed of a letter-shaped or T-shaped piece, and the elastic engagement spring is normally installed in the box to make the engaging locking part project forward, and when necessary, operate the unlocking part backward to engage. The locking part is configured to be retracted into the box.

[0010]

[Action]

 The main body support member is always projected, and is formed with movable locking claws that can be withdrawn when required, and is configured to engage and lock in the locking groove on the side of the hooking sealing cap. Etc. will not occur. Further, since the tip of the locking claw is formed to have an inclined cross-section with the lower side projecting gradually, and the engaging locking portion of this tip is configured to always project forward to the elastic spring, the instrument body is hooked. When it is lifted up along the ring cap and attached to the ceiling surface, the locking claw has an inclined cross section that is pushed by the side surface of the hook seal ring cap to retract and reach the locking groove. It is automatically engaged and locked by pressing. Therefore, the device body is connected in a one-touch manner. Further, when the device main body is removed, if the locking release portion is operated backward, the engagement locking is released, and the device main body is disengaged from the hook sealing cap by its own weight.
