Description

[Detailed Description of the Invention] The present invention relates to a glove mounting structure for waterproof lighting equipment used in bathrooms and the like.

In waterproof lighting equipment, a female thread is provided on the main body to which the lamp is attached, and the glove is attached to the main body by inserting the waterproof backing into the internal thread and screwing the globe into the thread.

In a waterproof lighting device having such a structure, especially in a device using a round fluorescent lamp, it is difficult to remove the globe because the height of the globe is low despite the diameter of the globe.

Causes of this include eccentricity of the screw, deformation of the glove due to strong hand pressure when putting on and taking off the plastic glove, and loosening of the backing.

The object of the present invention is to facilitate the removal of the glove from such waterproof lighting equipment.

Fig. 1 is a partially cutaway side view of an embodiment of the present invention, Fig. 2a
shows an exploded perspective view of its main parts.

1 is a dish-shaped main body with a downward opening, and 2 is the original fluorescent lamp.
It shall be attached to the ceiling surface with wood screws 3.

A female thread 4 is provided inside the main body 1, and a small gear 7 having a knob 6 is rotatably attached to the flange 5 of the opening with a screw 8.

9 is a glove, which has a male screw 1 screwed into the female screw 4 of the main body 1;
A collar 12 having gear-shaped unevenness 11 is provided on the periphery of the main body 1, and the gear 7 is configured to engage with the unevenness 11 when screwed onto the main body 1.

The glove 9 is tightened with a waterproof backing 13 interposed between it and the main body 1.

When removing the glove, if the glove is in close contact with the main body and it is difficult to turn it by hand, if you surround the gear 7 provided on the main body, the uneven surface 11 of the glove that meshes with this will be pushed.
The glove can be easily rotated.

It is sufficient that the thickness t of the gear-shaped uneven surface provided on the glove is such that the glove engages with the gear 7 for the first rotation.
After that, you can easily surround the glove with your hands.

Further, the gear 7 may have a tapered shape as shown in FIG.

3 and 4 show that the grooves 11 of the glove in the above-mentioned embodiment are provided parallel to the opening surface of the glove, and the gear 7 of the main body is
FIG. 2 is a side sectional view and an exploded perspective view of essential parts of another embodiment of the present invention in which the main body 1 is provided parallel to the opening surface of the main body 1 so as to engage with the unevenness 11.

FIG. 5 is a partially cutaway side view of another embodiment of the present invention, and FIG. 6 is a bottom view thereof.

In this embodiment, gear-shaped unevenness 1 is formed on the outer surface of the glove 9.
1, a shaft 14 is provided on the brim 5 of the main body 1, a lever 15 is rotatably provided on this shaft, and a pawl 16 is rotatably attached to this lever 15 with a pin 17. When removing the glove 9, The claw 16 is engaged with the unevenness 11 of the glove, the lever 15 is rotated around the shaft 14, and the glove 9 is pushed with the claw 16 to rotate the glove.When the glove is attached to the main body 1, As shown at the left end of the figure, rotate the claw 16 around the pin 17, fold it inside the lever 15, push up the lever 15, move it, and bring it into close contact with the side of the main body 1, so that the lever is in contact with the eye. It is constructed in such a way that it does not get in the way.

FIG. 7 shows a partially cutaway side view of still another embodiment of the present invention, and FIG. 8 shows a bottom view thereof.

In this embodiment, a link 18 is fitted into the main body 1, and a lever 21 having a pawl 20 is rotatably provided on this via a shaft 19. When removing the glove 9, the pawl 20 is pulled against the gear-like unevenness 11 of the glove. Turn the lever 2, press the glove, normally disengage the claw 20 from the groove 11 of the glove, and push the lever 21 upward along the shaft 19. , move the lever 21 to the main body 1
The problem was that the lever could be retracted by rotating it until it was flush against the side of the lever.

As described above, the present invention provides fine gear-like irregularities on the periphery of the glove, provides a retaining member that engages with the irregularities on the main body, and rotates the glove by rotating this retaining member. This allows the glove to be easily removed even when the glove is in close contact with the main body, and is particularly effective in waterproof lighting equipment equipped with a low-height glove using a round fluorescent lamp.
