Description

[Detailed description of the invention] [Technical field of the invention] This invention covers the automatic flasher of the outside light and checks whether the light bulb lights up when inspecting or replacing the light bulb of the outside light. This invention relates to an outer cylinder for covering an automatic flasher.

[Technical background of the invention and its problems]

Generally, outdoor light bulbs are turned on at night by an automatic flasher attached to the pole of the outdoor light. In addition, although it is possible to replace light bulbs in outdoor lights using a light bulb changer from the ground, it is necessary to confirm whether the light bulbs are lit or not during the replacement work.

Conventionally, in order to check whether a light bulb is on or not, a person climbs onto the pole of an outdoor light and covers the lighting part of the automatic flasher with a black cloth, etc., and the automatic flasher is kept in the same condition as at night and the light bulb is turned on. . However, such lighting confirmation work is not only time-consuming but also complicated.

Therefore, in order to be able to check the light bulb from the ground, it is conceivable to cover the lighting section of the automatic flasher by lifting the hollow cylindrical outer cylinder for covering the automatic flasher from below, which is open at the top.

However, even if such an outer cylinder for covering an automatic flasher is used, depending on the mounting structure of the automatic flasher, it may not be possible to sufficiently cover the lighting part of the automatic flasher. In other words, there are two mounting structures for automatic flashers: one is a mounting structure in which a holding horizontal plate is provided at the top of the automatic flasher and the automatic flasher is hung from above, and the other is a mounting structure in which a horizontal holding plate is provided at the bottom of the automatic flasher. There are two types of mounting structures that hold the automatic flasher by lifting it from below. In the case of an automatic flasher that has a mounting structure that is held from above, the automatic flasher covering outer cylinder described above can be fitted over the automatic flasher from below, so it is not necessary to cover the lighting part of the automatic flasher. This is possible, but in the case of an automatic flasher with a mounting structure that is held from below, the upper edge of the automatic flasher cover outer cylinder will collide with the holding horizontal plate, causing the automatic flasher cover outer cylinder to Since it is not possible to raise it any further, it becomes impossible to sufficiently cover the lighting area.

[Purpose of invention]

The present invention was developed taking the above points into consideration, and whether the automatic flasher is held from above or from below, in either case, the lighting part of the automatic flasher is raised from the ground. The purpose of the present invention is to provide an outer cylinder for covering an automatic flasher that can completely block light.

[Summary of the idea]

The present invention includes a substantially hollow cylindrical outer cylinder body, which has a storage section formed on the inner circumferential surface of the upper edge, a cutout on one side of the storage section, and a horizontal groove communicating with the cutout; This outer cylinder for covering an automatic flasher has a slide plate which is slidable and is disposed so as to freely close the notch, and has one side end cut off.

According to the present invention, when covering an automatic flasher held from below, the horizontal plate for holding the automatic flasher is placed on the notch provided in the outer cylinder for covering the automatic flasher,
After that, when the automatic flasher cover outer cylinder is rotated so that the holding horizontal plate bites into the horizontal groove connected to the notch, the sliding plate is stored with one end being pushed by the holding horizontal plate of the automatic flasher. Since the notch can be closed by sliding inside the part,
It is possible to completely block the light from the automatic flasher.

In addition, when covering the automatic flasher held from above, the lighting part of the automatic flasher can be completely blocked from light by simply covering it from below with the automatic flasher covering outer cylinder.

[Example of idea]

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 are diagrams showing an embodiment of an outer cylinder for covering an automatic flasher according to the present invention. In the figure, the reference numeral 11 is a substantially hollow cylindrical outer cylinder body that is open at the top. The outer cylinder main body 11 has an upper cylindrical part 11
a, a lower cylindrical portion 11b having a smaller inner diameter than this upper cylindrical portion 11a, and this lower cylindrical portion 11b.
The shaft insertion portion 11c has a smaller inner diameter. A protrusion 13 protruding radially inward is provided on the inner peripheral surface of the upper cylindrical portion 11a,
A storage portion 14 is formed by the step portion 11d between the upper cylindrical portion 11a and the lower cylindrical portion 11b and the protrusion 13. A notch 15 is provided on one side of the upper cylindrical portion 11a in which the storage portion 14 is formed, and a lateral groove 17 that communicates with the notch 15 and enters the storage portion 14 is provided at one end of the notch 15. ing. A slide plate 19 with one end cut off is slidably housed in the storage portion 14, and the slide plate 19 can slide to close the notch 15. Further, the reference numeral 21 is a shaft for operating the outer cylinder for covering the automatic flasher;
Reference numeral 23 is a pin for removing and removing the shaft. The shaft 21 can also be used as a shaft for operating a light bulb changer (not shown).

Next, the operation of this embodiment having such a configuration will be explained.

First, after replacing the light bulb in the outer tube, the shaft 21 is removed from a light bulb changer (not shown), and the shaft 21 is inserted and attached to the shaft insertion part 11c of the outer tube for covering an automatic flasher.

Next, when the automatic flasher held from below is covered with the automatic flasher covering outer cylinder, the automatic flasher 2 with the cable 31 attached as shown in FIG.
A worker gradually lifts the automatic flasher cover outer cylinder from directly below the automatic flasher 25 so that the holding horizontal plate 29 of the automatic flasher 25 enters the notch 15. In this way, the lighting part 27 and its surroundings are covered with the upper cylindrical part 11a of the outer cylinder for covering the automatic flasher. Next, when the shaft is operated and the casing 11 is turned clockwise so that the holding horizontal plate 29 of the automatic flasher bites into the horizontal groove 17, one end 19a of the slide plate 19 on the side of the horizontal groove 17 is inserted into the holding horizontal plate 29. To be pushed aside. Then, the other end 19b of the slide plate 19 shown in FIG.
The slide plate 19 moves forward toward the storage section 14.
The notch 15 is closed by sliding the inside.

On the other hand, as shown in FIG. 4, when covering the automatic flasher 35 that is held from above by the retaining plate 39 and the cable 41 is attached, the automatic flasher 35 is inserted from below using the outer cylinder for covering the automatic flasher. Just by covering it, the lighting section 37 and its surroundings can be completely shielded from light.

[Effect of idea]

As explained above, according to the present invention, when covering an automatic flasher held from below, the horizontal plate for holding the automatic flasher is placed on the notch provided in the outer cylinder for covering the automatic flasher, and then When this automatic flasher cover outer cylinder is rotated so that the holding horizontal plate bites into the horizontal groove communicating with the notch, the sliding plate slides inside the storage part with one end being pushed by the holding horizontal plate. , the notch can be closed. Therefore, the lighting part of the automatic blinker and its surroundings can be completely shielded from light.

On the other hand, when covering the automatic flasher held from above, the lighting part of the automatic flasher and its surroundings can be completely shielded from light by simply covering it from below with the automatic flasher covering outer cylinder.
