Description

[Detailed description of the device]

[0001]

[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 direct lighting fixture with a ceiling is used by attaching the main body of the fixture to the ceiling surface, and is often used for houses with a low ceiling surface.

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 indoor wiring. In addition, a hooking sealing body is arranged on the ceiling surface. In the case of a cord-hanging type luminaire, a conductive hook metal fitting is provided at the tip of the power cord and is mechanically and electrically hooked and connected to the hook sealing body. The hook sealing cap is attached so that the power supply and the equipment can be attached at the same time.

On the other hand, in the case of a ceiling-mounted lighting fixture, the body of the fixture 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 center of the fixture body, and the top side of the fixture body is placed on the ceiling surface. Although it is configured so as to be opposed to and directly attached to the ceiling surface, when attaching the equipment body to the ceiling surface, first attach a simple mounting bracket around the hook ceiling body and attach it to the ceiling surface. The attached mounting screw hooks the dharma hole provided in the main body of the instrument and temporarily holds 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.

[0006]

[Problems to be solved by the device]

 Therefore, as shown in FIG. 4, the applicant of the present invention has a hook sealing cap 4 in which engaging holes 3 for supporting the instrument body 2 are formed on both side surfaces of the lower surface of the hook sealing body 1. A ceiling-mounted lighting fixture 6 having a structure in which a main body support member 5 for supporting the main body 2 of the fixture is attached to the engagement hole 3 of the hooking sealing cap 4 is proposed. (Refer to Japanese Utility Model Laid-Open No. 62-54414) This ceiling-mounted lighting fixture 6 is constructed so that the main body 2 of the fixture is supported by the hook ceiling cap 4 itself, and like a simple mounting bracket, the ceiling is mounted. There is no need for screwing work to the surface, and the feature is that the mounting operation can be done in one-touch type. However, the hooking sealing cap 4 disclosed in Japanese Utility Model Laid-Open No. 62-54414 has a locking hole 3 for supporting the device body 2 formed on the side wall surface of the cap 4 body itself. However, the hook sealing cap 4 itself is made of resin for a few minutes, and there is a risk of breakage due to the engagement operation of the main body supporting member 5, which poses a problem in terms of durability and safety in long-term use. Further, since the main body supporting member 5 has a fixing structure only by bending a metal plate, there are problems in appearance that the mounting operation is difficult and the abutting portion of the lower surface of the instrument main body is damaged.

Therefore, the present invention has been made in view of the above, and provides a direct-to-ceiling lighting device that has durability and safety, is easy to install, and does not cause scratches or the like on the lower surface of the device body. The purpose is to obtain a support structure for the instrument body.

[0008]

[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. The hooking sealing ring cap is provided on the lower surface side of the exposed hooking sealing body, and the locking holes for supporting the instrument body are formed on both sides of the hooking sealing cap. In the lighting fixture directly attached to the ceiling in which the main body support member is locked in the locking hole to support the main body of the fixture, the hook ceiling cap is mechanically mounted on the top surface of the hook ceiling body. Electrically hooked metal fittings that are hooked and connected electrically, a cap body that has a stepped portion on which the metal frame body described below is attached and supported on the peripheral surface of the side wall, and an attachment that is attached to the stepped portion on the top Mouth, cross section with the locking holes formed on both sides The main body supporting member is constituted by a locking claw that is mounted on the lower surface of the instrument main body so as to be capable of advancing and retracting in opposition to the locking hole. . Further, the lower surface and the inner and outer surfaces of the metal frame body are integrally covered with a resin cover.

[0009]

[Action]

 Although the cap body of the hooking sealing cap having the above-described structure is made of resin, the engaging hole portion into which the engaging claw of the main body supporting member is engaged and engaged is a metal frame body, which is worn or damaged. It is safe and durable even if used for a long time. Moreover, since the main body supporting member has a movable structure that can be moved back and forth, the mounting operation can be extremely simple. In addition, the bottom surface of the instrument body is not scratched. Further, since the lower surface and the inner and outer surfaces of the metal frame body are integrally covered with the resin cover, the metal frame body is not directly exposed below the hooking sealing cap, and the appearance is not impaired.
