Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an outer shell structure for an automatic flasher, and more particularly to an outer shell structure for draining water from an automatic flasher.

[Prior art] Automatic flasher 8 for flashing outdoor lights such as security lights
It is as shown in the figure, with a transparent plate on the body 1a)
Casing 1 covered with #JtrIl cover 1b
A photodetector 5 is housed in the holder, and the holder is used outdoors by being attached using a mount 4. The automatic flasher 8 automatically flashes the security light according to the outdoor illuminance. Since the automatic flasher 8 is exposed to wind and rain outdoors, rainwater may enter the casing 1 through the outlet of the wiring 6 of the casing 1 or the gap between the body 1a and the cover 1b, or water may accumulate inside the casing 1 due to condensation. Water constantly enters the
It accumulates. If water enters the casing 1, components such as the photodetector 5 inside the casing 1 will deteriorate, so in order to prevent this, conventionally, a drain hole 7 was provided in the casing 1 to prevent water from accumulating. 0 For example, as shown in the figure, a drain hole 7 was provided on the lower surface of the cover 1b. By the way, the effectiveness of draining water and various installation methods should be determined by making the drain holes 7 larger depending on the posture, and the more they are, the better. It was something that caused it to happen.

[Objective of the Invention 1 The present invention has been made in view of the above-mentioned points, and an object thereof is to provide an outer shell structure for an automatic flasher that prevents insects and dust from entering and efficiently discharges water. 6 [Disclosure of the Invention 1 The automatic flasher of the present invention is an automatic flasher that is installed outdoors and turns on and off depending on the outdoor illuminance. A department has been established,
The opening is covered with a water-permeable plate that prevents dust and insects from entering the casing, but also has many fine pores that allow internal water to drain, preventing insects and dust from entering the casing. At the same time, water can be efficiently discharged outside the casing.

The automatic flasher according to this embodiment, as shown in FIG. 1, is the same as that described in the conventional example except for the casing 1. The same sign shall be used. The casing 1 that houses the optical patient detector 5 with automatic flashing 138 is composed of a body 1a and a cover 1b, and the installation time is 14:2.
0, the cover 1b is attached to the shade or ball of an outdoor light such as a security light, and the cover 1b is on the underside of the casing 1. Therefore, water that has entered the casing 1 collects on the bottom inner wall of the cover 1b. The bottom surface of the cover 1b is provided with an opening 2 for draining water. As shown in FIG. 2, the opening 2 is covered from the inner wall side of the cover 15 with a water-permeable plate 3 formed in a thin plate shape from an open foam of a polymeric material such as urethane or 7-El. ing. That is, permeability @3
It has many tiny pores that allow water to pass through, but prevent insects and dust from passing through. A recess 9 is provided in the bottom of the cover 1b at the portion where the water-permeable plate 3 contacts, and the water-permeable plate 3 is attached to the four parts 9 by adhesive or thermal bonding.

At this time, the upper surface of the water-permeable plate 3 is covered with the cover 1 around the opening of the fourth part 9.
b Be flush with the bottom inner wall. In this way, by providing the four parts 9, the upper surface of the water-permeable plate 3 is flush with the bottom inner wall of the cover 1b, so that water does not flow to the edge of the water-permeable plate 3 due to the difference in level between the upper surface of the water-permeable plate 3 and the bottom inner wall of the cover 1b. Prevents it from remaining. As mentioned above, the opening 2 is covered with a water-permeable plate 3 that allows water to pass through but not insects or dust, so the size of the opening 2 is large regardless of the size of the insects or dust. This makes it possible to improve the efficiency of draining water inside the casing 1.

In the above embodiment, the cover 1b has one opening WS2, but a plurality of openings WS2 may be provided.For example, as shown in FIG.
In order to efficiently drain water even if there is a possibility that water may accumulate on both sides of the bottom of the cover 1b,
A configuration may be adopted in which two slit-shaped openings 2a are provided on both sides of the bottom surface of b.

In this case as well, as in the previous embodiment, the opening 2a is covered with a water-permeable plate 3 that allows water to pass through but not insects or dust, so it is possible to increase drainage efficiency by providing a plurality of openings 2a. It is possible.

In addition to the above-mentioned fixtures, a uniquely shaped mounting bracket 12 as shown in FIG. 4 can be used as a fixture for the automatic flasher 8 of this oak tree. That is, as shown in FIG. 5, the fixture 12 in the figure has a vertical piece 13 and a
uL 1! ';> f tank tD 'L h i ia,
The fv attachment 12 is a metal plate bent into an abbreviated shape.
- One piece is a vertical piece 13 and the other piece is a horizontal piece 14, and the tip of the horizontal piece 14 is bent to form an inclined piece 15 that is inclined with respect to the horizontal piece 14. The vertical piece 13 of the mounting J% 12 is provided with screw holes IB and ribs 19 and is attached to the cap of an outdoor light 22 such as a security light or to the ball 21. A small screw hole 16 is provided in the mounting Rt12 from the horizontal piece 14 to the inclined piece 15, and the automatic flasher 8 can be attached to the mounting fixture 12 by passing the screw 17 through the screw hole 16 and screwing it into the automatic flasher n8. It can be fixed to. As shown in FIGS. 6 and 7, the automatic flasher 8 is temporarily fixed to the fixture 12 with the screw 17, and the horizontal piece 1 is inserted along the screw hole 16 of the fixture 12.
4 and the inclined piece 15, the automatic flasher 8 can be fixed to the fixture 12 in different postures.

In the above-mentioned mounting 14c12, the automatic flasher 8 is slidably temporarily fixed using screws 17, and the vertical piece 13 of the fixture 12 is fixed to the cap of an outdoor light 22 such as a security light or to the ball 21. Since the automatic flasher 8 is slid between the vertical piece 14 and the inclined piece 15, the automatic flasher 8 can be easily positioned in a predetermined position at the location where the fixture 12 is installed.
The automatic illumination device 8 can be fixed to the horizontal piece 14 or the inclined piece 15 of the mounting plate 12 in a predetermined posture.

[Effect of the invention 1] The automatic flasher of the present invention is an automatic flasher that is installed outdoors and turns on and off depending on the outdoor illuminance. The opening is covered with a water-permeable plate that has a large number of fine pores that prevent dust and insects from entering the casing, but allows water to drain inside. , the openings can be set very lightly or a plurality of openings can be provided, and the water inside the casing can be efficiently discharged to the outside of the casing.
