Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a hanging device for a lighting fixture, particularly an insect-proof and easily installed lighting fixture.

[Prior art]

Figure 1 shows a known example on the market, in which 1 is a recessed hook rosette having an ear 2 and an outlet 3, 4 is a chain held in this ear, and 5 is a chain that is held by this ear. 6 is a power supply hole formed in the center of the main body of the device; 7 is an insect-proof bushing that is fitted into the power supply hole and has a through hole in the center; 8 is a device near the through hole; A cord stopper attached to the main body, 9 is a power terminal board provided on the main body of the appliance near this cord stopper, 10 is a plug part connected to the above-mentioned outlet part, and the other end passed through the through hole of the insect-proof bushing to connect the power terminal board. This is a cord with a plug that is connected to the cord and fixed with a cord stopper in the middle.

Also, Figures 2 and 3 are for example published in Japanese Patent Application Laid-Open No. 58-19805.
1 is a perspective view showing a conventional easy-to-install, insect-proof lighting fixture shown in the publication, and if the parts corresponding to FIG. 1 are omitted, 11 is a mounting screw hole provided in the ear portion 2;
13 is a knob screw that is screwed into this screw hole, 13 is a daruma hole provided at a position opposite to this thumb screw,
14 is a hooking ceiling cap with a cord, one end of which is connected to a power terminal board provided near the Daruma hole, and 15 is a packing provided on the back of the instrument body.

A hanging device for a conventional insect-proof lighting fixture is constructed as shown in Fig. 1, in which a cord with a plug 10 is inserted from inside the fixture through a power hole 6 in the center of the fixture body 5 through an insect-proof bushing 7 to prevent insects and dust from entering. It led out to the back of the device and was connected to the power supply to the recessed hook rosette 1. On the other hand, from the viewpoint of labor saving in installation work, a simple installation type appliance constructed as shown in FIGS. Screw the thumb screw 12 into the screw hole 11 of No. 2, and then screw this thumb screw 1 into the screw hole 11 of No.
2 is passed through the daruma hole 13 of the instrument body 5, the instrument body 5 is rotated, the knob screw 12 is tightened, and the hook sealing cap 14 is connected to the recessed hook rosette 1. be.

However, the main body of this easy-to-install appliance has large through-holes such as the Daruma hole 13 and the power supply hole 6, and when using it as a direct-ceiling type to make it insect-proof, for example, as shown in Fig. 4. As shown in the figure, the gap between the back of the appliance body and the ceiling surface was closed with packing 15, but when used as a hanging type, it is necessary to close many holes such as the power hole 6 and the daruma hole 13. If the cord with plug 10 needs to be fixed with the cord stopper 8 and you want to add a hanging device separately and change it to a hanging appliance based on a ceiling-mounted appliance, use a seal etc. for the attachment hole of the cord stopper 8. There are many cost and technical difficulties, such as the need to either block the cord stopper 8 or attach it to the direct-mounted fixture from the beginning. In addition, even in the example shown in FIG. 1, when a ceiling-mounted fixture is used in a suspended form, the user must also attach the cord stopper 8 when attaching the plug cord 10. It had the following drawback.

[Summary of the idea]

This idea was made with the aim of improving these drawbacks, by adding a flat plate as a part of the hanging device, and giving this flat plate an insect-proofing function to prevent insects and dust from entering, and a cord with a plug. 10 is fixed and attached by the cord stopper 8 on the manufacturer's side, thereby proposing a hanging device that is low cost and requires no effort on the user's side.

[Example of idea]

FIG. 5 is a perspective view showing an embodiment of this invention, and numerals 1 to 15 are exactly the same as the conventional device described above. Reference numeral 16 denotes an insect-proof plate 18 provided with a mounting screw hole 17 at a position opposite to the Daruma hole 13 of the instrument body 5;
An insect-proof bushing 7 that is fitted into a power hole provided in the center of the insect-proof plate 18 and has a power line hole; This is a suspension set consisting of a cord with a plug 10 and a suspension chain 4 fixed to a mounting hole.

The hanging device configured as described above is provided to the user as an easy-to-install, direct-mounted device without the hanging set 16, and in this case, the packing 15 connects the device body 5 to the ceiling surface. The gap between the two is closed, and it has the function of preventing insects from entering through the Daruma hole 13 and the power supply hole 6. Also, when using this as a hanging type, which is not often used, the above hanging set 16 is sold separately. It may be added as a part; in this case, first attach the mounting screw hole 17 of the insect-proof plate 18.
Align it with the daruma hole 13 of the device body 5, screw the suspension set 16 excluding the chain 4 with the knob screw 12, connect the cord with plug 10 to the power terminal board 9, and the insect-proof plate 18 As a result, the daruma hole 13 and the power supply hole 6 are closed, and the device can be used as a hanging device with the function of preventing insects from entering.

[Effect of idea]

As explained above, by adding one low-cost part, the insect-proof plate 18, this invention makes it possible to hang and use insect-proof lighting fixtures with a simple installation, which has not been possible in the past.
In addition, the cord with plug 10, the bush 7, and the cord stopper 8 are integrated into the insect-proof plate 18 to form a set of hanging parts, which makes it easy to change from a direct-mounted type to a hanging type, and also makes it easy to change from a direct-mounted type to a suspended type. Since the cord 10 is separate from when hanging, there is no need to consider storage of the cord 10 when directly attached.
