Description

  The present invention includes a lighting device for a ceiling including a substantially flat plate-like fixture body arranged horizontally, and a circular and bowl-shaped translucent cover that is detachably attached to the lower surface side of the fixture body. It relates to the instrument.

  In rotating and hanging ceiling lighting fixtures, the translucent cover is pressed against the fixture main body mounted on the ceiling surface from below, for example, it is turned a little clockwise and both are detachably attached. It is designed to be installed by pushing and turning. When removing the translucent cover, the translucent cover is removed from the instrument body by turning it counterclockwise.

  Since it is difficult to push and rotate the translucent cover, which is often a large component, with both hands, the frictional force between the instrument body and the translucent cover during pushing and turning is minimized. It is desirable to facilitate the pushing operation. However, it is not easy to reduce this frictional force. One reason for this is that there is a large variation in the plate thickness of the translucent cover formed of the compressed air molded product. Therefore, it is necessary to provide a gap (play) between the instrument body and the translucent cover attached to the instrument body. However, if an excessive gap is provided, there is a problem that insects enter the inside through the gap. To do.

  For example, as shown in FIG. 7 of Japanese Patent Application Laid-Open No. 11-238409 (Patent Document 1), as a conventional rotating and hanging ceiling lighting fixture, the top plate of the fixture body and the tip of the rising portion of the globe are sponges. In some cases, the insect-proofing property is ensured by abutting through a cylindrical packing.

Japanese Patent Laid-Open No. 11-238409 (FIG. 7)

  However, in Patent Document 1, the tip of the rising part of the glove is brought into contact with the sponge-like packing to prevent insects. Therefore, there is a problem that it is difficult to achieve both reliable insect prevention and pushing workability. That is, in Patent Document 1, consideration is given to improving the workability of pushing by making the tip of the rising part of the globe contact the lower surface of the sponge packing, but the sponge packing takes a long time. In other words, the contact portion of the sponge-like packing may be plastically deformed and a gap may be formed between the instrument body and the glove so that insects can enter. Therefore, it is conceivable that the flat part of the glove is brought into contact with the sponge-like packing, but in this case, the friction coefficient between the flat part of the glove and the sponge-like packing becomes large, and the pushing operation becomes extremely worse. Will occur.

By combining, the translucent cover 6 is suspended from the instrument main body 1.

  This attachment method will be described more specifically.

First, the upper end portion 6c of the cover is inserted into the lower folding edge 2 at the position shown in FIG. 7 (a), and the flat portion of the cover peripheral collar portion 7 is brought into a state of being entirely pressed against the hair-like portion 11 from below. When the flat surface portion of the cover peripheral flange portion 7 is pressed against the ciliary portion 11 in this manner, the ciliary body is deformed, for example, divided into an inner peripheral side and an outer peripheral side. Therefore, a large force is not required for the pressure contact work, and a pressure contact state can be obtained very easily.

  From this state, the translucent cover 6 is rotated as indicated by the white arrow in FIG. 7A, and the cover convex portion 8 is engaged with the attachment of the cover attachment 4 as shown in FIGS. 7B and 8. Engages with part 4b. When the translucent cover 6 is rotated, the ciliary body is deformed along the moving direction of the flat surface portion of the cover peripheral flange portion 7 (see the state of the ciliary portion 11 in FIG. 6). Therefore, a large force is not required for the rotation operation, and the rotation can be performed very easily.

In the state where the cover convex portion 8 is engaged with the fixture engaging portion 4b, the ciliary portion 11 is pressed by the cover peripheral flange portion 7, so that the ciliary body of the ciliary portion 11 is deformed and the cover peripheral portion is deformed. A gap between each ciliary body between the collar portion 7 and the instrument main body 1 (specifically, the base portion 10) is reduced. Thereby, it is possible to prevent insects from entering the inside through the ciliary portion 11. In this embodiment, in particular, since the entire lower surface of the ciliary portion 11 is pressed by the flat portion of the cover peripheral collar portion 7, the gap between the ciliary bodies can be extremely small, and insects can be more effectively invaded. This can be prevented more reliably.
