Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a fixture mounting mechanism suitable for simplifying the installation work of direct-mounted lighting fixtures.

[Background of the invention]

As shown in Figures 3 and 4, conventional direct-mounted lighting fixtures were attached to the main body with a lamp socket attached using wood screws, etc., by placing a glove on the screws of the lamp socket and tightening the socket holder. . For those that used a hook socket, a screw was installed inside the ceiling cover and was tightened to the screw of the hook socket without a glove.

For this reason, a connector is required to connect the power source, and furthermore, it is difficult to install wood screws from within a narrow space of the device, resulting in a lack of consideration for installation work.

In addition, for those that use a hook socket, it is necessary to take further safety into consideration, such as the hook socket coming off when replacing a light bulb, and the hook fitting of the hook socket breaking due to the tightening tension of the ceiling cover.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a lighting fixture that can reduce the number of man-hours required for installing the lighting fixture and ensure safety after installation.

[Summary of the invention]

Most of the power supplies for lighting equipment in general houses and apartment complexes are made up of hanging rosettes, and in order to accommodate these, hanging fixtures with hanging ceilings have become mainstream. On the other hand, since each type of direct-mounted fixture has a different mounting method, we investigated the development of a direct-mounted lighting fixture that can be attached to a hanging rosette in the same way as hanging fixtures.

[Embodiments of the invention]

One embodiment according to the present invention is shown in FIGS. 1 and 2. FIG. A hook socket 2 having a screw 3 on a rectangular hook ceiling body 1 having a connecting mechanism for connecting to a power source is screwed and electrically connected by a hook fitting. The sealing cover 4 has a rectangular hook sealing body 1 on its inner surface, a U-shaped rotation prevention wall 5 that fits around the outer periphery of the hook socket 2 in a locked and fixed state, and a guide groove 6 for the globe 11 and a hook on the outer periphery of the lower surface. An insertion hole 7 for the socket 2 is provided. The inner surface of the socket holder 8 is provided with a screw 3' to fit into the screw 3 of the hook socket 2, a cylindrical protrusion 9 to fix the sealing cover 4, and a locking collar 10 for a globe 11. In this case, the dimensions of the protrusion 9 and the ceiling cover 4 are set to a height that matches the length of the screw 3 of the hook socket 2. That is, when the socket holder 8 is fully tightened to the screw 3 of the hook socket 2, the size is such that the guide s6 of the sealing cover 4 can fix and stop the tightening.

The hook socket 2 is engaged with the hook ceiling body 1 by these components, and the ceiling cover 4 is inserted. Next, by inserting the glove 11 and tightening the socket holder 8 to the end, the sealing cover ~4 is fixed, and the glove 11 can also be locked. This prevents the hook socket 2 from rotating and falling off when replacing the lamp 12, and also prevents tension on the hook fitting in the hook socket 2 due to the tightening of the socket holder 8.

〔Effect of the invention〕

According to the present invention, the installation work of the appliance is performed only on the main body of the rectangular hook ceiling, making the work easier and ensuring safety after the appliance is installed.

Additionally, since it can be attached to the existing hook ceiling body, there is no need for electrical work after purchasing the appliance, making it possible to sell it over the counter.

Claims (1)

[Claims] In a direct-mounted lighting fixture in which a hook socket is attached to a rectangular hook ceiling body, there is a roughly U-shaped rotation prevention wall on the inner surface to prevent rotation of the hook socket, and a guide groove for the glove and an insertion hole for the hook socket on the outer periphery of the bottom surface. A direct-mounted lighting fixture characterized in that the ceiling cover is fixed and the glove is locked by tightening the ceiling cover provided with the ceiling cover and the socket holder provided with projections on the top and side surfaces of the hook socket to the screws of the hook socket.
