BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a key with an illuminated light (light emitting diode, incandescent lamp) built inside.

0002

2. Description of the Related Art When using a key at night, it may be difficult to open the key because the keyhole cannot be seen due to darkness. Therefore,
A lighted key has been proposed in which a light is provided on the key grip. FIG. 4 shows a key 10 with an illumination light described in Japanese Utility Model Publication No. 56-169059, and as shown in the figure, a battery 13 is attached to a grip 12 attached to the head of a metal key body 11. A light bulb 14 is provided, and when the battery 13 is pressed, the switch is turned on, and the light bulb 14 lights up, illuminating the tip of the key.

0003

[Problems to be Solved by the Invention] However, the key 10 with an illuminated light according to the conventional example described above is not waterproof or drip-proof at all, so if the key gets wet with sweat or gets wet with rain, etc. If water adheres to the device or for other reasons, the water gets inside and corrodes the electrodes or other parts, resulting in an extremely short service life. The present invention was made in view of such circumstances,
To provide a key with an illumination light that prevents water from entering inside even if some water adheres to it and has a long service life.

0004

[Means for Solving the Problems] A key with an illuminating light according to claim 1, which meets the above object, includes a key body in which a key thread is formed on at least one side, and a key body connected to the key body and having a replacement part inside. A key with an illuminated light comprising a battery and a grip connected to the battery via a switch and having an illuminating light facing the tip of the key. The grip body is divided into two parts, and the battery, the switch provided with a waterproof cover, and the lighting lamp arranged in a waterproof state are housed in the grip main body, and
The head of the key body is housed in the grip body, and at least the battery,
A sealing material is arranged to seal the switch and the illumination light.

[0005]

[Function] In the key with an illuminating light according to the present invention, the grip is divided into two in the thickness direction into a grip body and a cover body, and the battery, switch, and illuminating light are housed in the grip body, and the above-mentioned key is housed in the grip body. A sealing material is placed between the grip body and the lid to seal the battery, switch, and lighting lamp, so that when the lid is completely closed, the internal Batteries, switches, and lights will be sealed. Therefore, water, sweat, etc. do not enter the inside, and corrosion due to these does not occur.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments embodying the present invention will be described with reference to the attached drawings to provide an understanding of the present invention. FIGS. 1 to 3 show a key 16 with an illumination light according to an embodiment of the present invention, and as shown in the figures, the key 16 with an illumination light is
A grip body 17, a lid body 18 that covers the grip,
A metal key body 19 (only a part of which is shown) whose head is disposed in the grip body 17, and a light emitting diode 2 which is an example of a lighting lamp housed in the grip body 17.
0 and a battery 21. These will be explained in detail below.

The grip body 17 and lid body 18 are AB
It is made of an electrically insulating synthetic resin such as S, polypropylene, or polycarbonate, and has a light emitting diode housing 22, a battery housing 23, and a key body housing 24 formed inside. 0.1 to 0 on the back side of the battery storage section 23.
．． A metal plate 25 is arranged with a gap of 4 mm, and this metal plate 23 is attached to a switch plate 27 arranged with a U-shaped gap 26 on three sides. The sealing plate 28 made of relatively flexible synthetic resin (for example, polypropylene, artificial rubber, silicone resin, PVC, etc.) is completely bonded by ultrasonic bonding or adhesive bonding to prevent water from entering inside. It has become. Therefore, the pedestal 23a of the battery storage section 23 is attached to the metal plate 25.
Since there is a certain small gap between battery 2 and
1 and the metal plate 25 do not come into contact with each other, but by pushing the seal plate 28 from the outside, the switch plate 27 is pushed inward and bent, so that the metal plate 25 on which it rests comes into contact with the battery 25. Therefore, the switch plate 27 and the metal plate 25 constitute a switch.

In this embodiment, one side of the switch plate 27 is integrated with the grip body 17, but it is also possible to provide the above-mentioned gaps on four sides so that the switch plate and the seal plate are integrated.

A light emitting diode 20 is installed in the insertion hole 29 in the light emitting diode storage section 22 with the tip of the light emitting diode 20 facing toward the key. An adhesive is filled between the light emitting diode 20 and the light emitting diode 20 to achieve a complete seal. One lead wire 30 of the light emitting diode 20 is covered with a vinyl tube 31, which is an example of a flexible insulating tube.
Only the tip is bent toward the battery so that it comes into contact with one pole of the battery. In addition, a light emitting diode 20
The other lead wire 32 is brazed to the metal plate 25.

The head of the key body 19 is housed in the key body storage portion 24, and the head is provided with three screw holes 33, and the grip body 17 is provided with three screw holes 33. Three female screw holes 34 corresponding to 33 are provided. An O-ring groove 35 is formed surrounding the battery housing section 23 and the light-emitting diode housing section 22, into which an O-ring, which is an example of a sealing material, is fitted. In addition,
It is also possible to use a sheet packing instead of this O-ring. Further, a female screw hole 36 is also provided in the upper part of the grip main body 17.

On the other hand, as shown in FIG. 3, the lid body 18 has four screw holes 37 provided with seat holes for accommodating screw heads corresponding to the screw holes 33 and the female screw holes 36. It is provided. As a result, the lid body 18 is screwed to the grip body 17 with screws 38, thereby making it possible to completely seal the interior with the O-ring. Therefore, when using the illuminated key 16, the light emitting diode 20 is energized by pinching the grip and pushing the seal plate 28. In the embodiment described above, the female threaded holes 34 and 36 are directly carved into the grip body, but it is also possible to embed another metal bar having irregularities around the periphery and provide the female threaded holes in the bar metal. It is also possible to extend the head of the key body 19 to the key ring hole 39. In this case, it is also possible to extend it slightly from the inside of the key ring hole 39 or to make it flush with the inside of the key ring hole 39. be.

[Effects of the Invention] As is clear from the above description, in the key with an illuminated light set forth in claim 1, since the battery, light emitting diode, etc. are completely sealed, sweat or other water can prevent the interior from being damaged. Electrical components such as batteries are not corroded and can have a long service life. Furthermore, even if seawater or the like is accidentally splashed on the key, the illuminated key will not become unusable.
