Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a switch pull cord position display device that makes it easy to locate the pull cord position even at night.

BACKGROUND OF THE INVENTION Conventionally, it has been known to pass a pull cord through a cover that includes a built-in indicator light in order to indicate the position of the pull cord of a switch.

Problems to be Solved by the Invention The above-mentioned conventional technology is designed to prevent exposure to light from other than the hole through which the drawstring of the cover is passed, but it is difficult to obtain effective light-gathering power to indicate the position of the drawstring. There was a problem that the display was extremely dark because there was no effective means to improve it. Therefore, the present invention:
The purpose is to solve the above problems.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention has the following features:
The light of the indicator light is introduced into a transparent body whose entire surface is coated with a light reflecting film except for the ends, and the pull string of the switch is passed through the end, and the transparent body, the indicator light, and the switch are the same. The sub-chassis is attached to a chassis equipped with a light source, a globe covering the chassis has a hole through which an end of the transparent body passes, and an end surface of the transparent body is substantially flush with a lower surface of the globe. A pull cord position display device for a switch is configured.

Effect: According to the above-described means of the present invention, the light from the indicator lamp is transmitted through the transparent body while being reflected by the light-reflecting film, and can be effectively focused at the end, so that the position of the drawstring can be clearly identified. can be displayed.

Furthermore, since the transparent body, indicator light, and switch are mounted on the same subchassis, these mutually related parts can be relatively well positioned on the same subchassis and can be assembled efficiently. Furthermore, the glove that covers the chassis to which the sub-chassis is attached and which is equipped with a light source has a hole through which the end of the transparent body passes, and the end surface of the transparent body is almost flush with the bottom surface of the glove. Because the glove is covered with light, exposure from the end of the transparent body looks as if part of the glove is glowing, making it possible to display the position of the switch pull string in an attractive manner.

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

First Embodiment (FIGS. 1 to 4) A chassis 1 is equipped with a light source 2 consisting of a straight tube fluorescent lamp. A sub-chassis 3 is attached to an end of the chassis 1. The sub chassis 3 includes a switch 4 and its cover 5, a transparent body 6 made of acrylic resin or the like having a light reflecting film 6a coated with aluminum vapor deposition on substantially the entire surface except for the ends, a miniature bulb 7 and its socket 8, etc. Installed. A vacant space 6b is provided at the other end of the transparent body 6, and an indicator light 9 such as a neon lamp or a light emitting diode is provided in the vacant space 6b, and its lead wire 9a and current limiting resistor 10 are connected to the switch 4 through the notch 6c. connected to. The pull string 4a of the switch 4 is passed through the hole 6d at the end of the transparent body 6. The glove 11 is detachably attached to the chassis 1 with a latch fitting (not shown), and has a hole 11a through which the end of the transparent body 6 passes. A ring-shaped butting 12 made of milky white polyethylene, polyvinyl chloride, etc. is slidably fitted to the end of the transparent body 6. The bushing 12 is a transparent body 6
It is prevented from coming off at the large diameter portion 6e at the end. The bushing 12 is forcibly inserted beyond the outer diameter of the large diameter portion 6e, and the bushing 12 is forced into the second part of the transparent body 6 provided as necessary.
It can be slid between the large diameter portion 6f and the large diameter portion 6f.
Further, 13 is an insulating lid that closes the empty space 6b. Note that instead of providing the empty chamber 6b in the transparent body 6, a separate storage chamber may be provided at the other end of the transparent body 6.

Second Embodiment (FIGS. 5 to 7) In this example, in order to make the transparent body 6 relatively short, a mounting base 14 that also serves as a switch cover is provided on the sub-chassis 3, and this mounting base 14 is transparent. body 6
This is the one with the .

In the above embodiment, the light reflecting film 6a was applied to substantially the entire surface above the large diameter portion 6f.

According to the above configuration, the light from the indicator lamp 9 introduced into the transparent body 6 is transmitted toward the end, and since substantially the entire surface of the transparent body 6 except for the end is coated with a light reflecting film. The brightness of the end portion is significantly improved compared to the conventional example, making it extremely easy to find the drawstring 4a at night. Also, in the daytime, in the conventional example, the part where the drawstring 4a passes does not shine at all, but in the present invention, when a neon lamp with the same brightness as the conventional example is used, it shines well even in the daytime, and the accessory It is also useful as a light.
In addition, since the insect repellent bushing 12 is slidably fitted to the end of the transparent body 6, the glove 11
The hole 11a can be made relatively large in diameter, and when attaching the glove 11 to the chassis 1, the transparent body 6 can be inserted into the hole 11a.
It has the advantage of making it easy to fit the ends of the
When the glove 11 is removed from the chassis 1, the bushing 12 is supported by the large-diameter portion 6e and is held attached to the transparent body 6, so that it does not wrap around the glove like a conventional bushing attached to the drawstring 4a. It doesn't even stick.

Further, since the transparent body 6, indicator light 9, and switch 4 are mounted on the same sub-chassis 3, these mutually related parts can be relatively well positioned on the same sub-chassis 3, and can be assembled efficiently. Furthermore, the glove 11 that covers the chassis 1 to which the sub-chassis 3 is attached and which is equipped with the light source 2 has a hole 11a through which the end of the transparent body 6 passes, and the end surface of the transparent body 6 is substantially flush with the lower surface of the globe 11 (almost flush with the bottom surface of the globe 11). height), the transparent body 6 is covered with the globe 11 except for the end surface, so the transparent body 6
The exposure from the end surface of the globe 11 looks as if a part of it is shining, and the pull string 4 of the switch 4
The position of a can be displayed in an elegant manner.

Although the indicator light 9 is generally turned on when the light source 2 and the miniature bulb 7 are off, it may be turned on all the time. Also, the drawstring 4a is a ball chain,
Can be replaced with metal wire, etc. In addition, since the light reflecting film 6a is masked except for the portions that require exposure, it is possible to prevent the intermediate portion of the transparent body 6 from appearing faintly shiny through the light-transmitting globe 11.

Effects of the invention As is clear from the detailed explanation above, according to the present invention, the position of the switch pull cord can be displayed with sufficient clarity, making it easy to find the pull cord at night, and making it easy to locate the switch during the day. It has the effect of looking bright at times and being useful as an accessory light.

Further, the related parts for indicating the position of the switch pull string are relatively well positioned on the same subchassis and can be assembled efficiently. Furthermore, since the parts other than the end faces of the transparent body are covered with the globe, exposure from the end faces of the transparent body looks as if a part of the globe is shining, and the switch pull string position can be displayed in an attractive manner.
