Description

[Detailed description of the invention] [Field of application of the invention] The present invention relates to a lighting device suitable for illuminating a keyhole.

[Background of the invention]

When trying to insert the key into the keyhole, at night, etc.
It's often inconvenient to know where the keyhole is because it's dark. Conventionally, in order to eliminate such inconvenience, a key chain type lighting fixture as shown in FIG. 1 has been devised. That is, a disc-shaped case 1, a tungsten light bulb 3 provided facing a window 2 opened at the periphery of the case 1 (2), two 1.5V dry batteries housed in the case 1, and a case. It is made up of a slide switch 4 formed on the top surface of 1 and a chain 5 to which a key is locked.

However, the device shown in FIG. 1 has the disadvantage that the case 1 is large because it uses a tungsten light bulb and a dry cell battery. In addition, due to the large size, it is difficult to insert the key while illuminating the keyhole with one hand, so the operation must be performed with both hands, making it extremely inconvenient to use.

[Purpose of the invention]

An object of the present invention is to provide a keyhole lighting fixture that is small, lightweight, and easy to use.

[Summary of the invention]

The present invention provides a main body consisting of a disc-shaped battery and a light emitting element placed on the top surface of the battery and connected via a switch means, a storage portion into which the main body is fitted, and a storage portion formed on the bottom surface of the storage portion. and a case having a key attachment part, and the switch means is made of a spring member welded to one lead terminal of the light emitting element and disposed with a constant gap from the top electrode of the battery. The device includes a switch member and an insulating member provided at the welded portion of the switch member to maintain a gap between the upper surface electrodes, and at least a top portion of the storage portion is formed of an elastic member, and a tip portion of the light emitting element is formed of an elastic member. A through window is formed at the facing position, the key mounting part has an opening formed on the lower surface into which the main body can be inserted, and the extending direction of the needle leg is made to match the light emission direction of the light emitting element, In addition, by forming an insertion piece that holds the key head in a removable manner, it can be attached to the head of the key and integrated with the key, and the top of the case can be attached by holding it with fingers or the like. By simply pressing the button, the switch means is closed and the light emitting element is turned on, thereby improving usability.

[Embodiments of the invention]

Hereinafter, the present invention will be explained based on illustrated embodiments.

FIGS. 2A and 2B show a sectional view and a bottom view of an embodiment of the present invention, and FIG. 3 shows a perspective view thereof.

In those figures, the case 11 is made of rubber or synthetic resin (
For example, it is integrally formed with an elastic material such as a thermoplastic polyurethane elastomer (manufactured by Nippon Elastolan Co., Ltd.), and includes a storage part 1ia into which a main body consisting of a light emitting diode 12 and a battery 13 is inserted, and a head of a key 14. It includes a key mounting part 11b into which the part 14a is inserted. A through window 15 is formed on the peripheral side surface of the storage portion 11a. Key attachment part 11
An opening 16 through which the main body can be inserted is formed in the center of the bottom surface of b, and an opening 17 through which the leg portion 14b of the key 14 is passed through, and a peripheral protrusion of the head 14a can protrude from the peripheral edge of the bottom surface. An opening 18 is formed. The remaining bottom surface formed in this manner holds the insertion piece 11 that holds the key head 14ai.
c. The opening 17 and the through window 15 are connected to the case 1.
They are formed around the same position in the circumferential direction of No. 1. Note that 19 is a hole for locking a chain' such as a key chain (not shown).

(5) On the other hand, the battery 13 is, for example, a rechargeable battery formed in a disc shape, and substantially the entire upper and lower surfaces of the disc are covered with electrodes. A light emitting diode 12 as a light emitting element is mounted on the upper peripheral edge of the battery 13. In this case, the battery 1 is made of light emitting diode 12 and adhesive 20.
It is desirable to fix it on the top surface of 1. light emitting diode 1
One of the lead terminals 21 of 2 is cut short, and a piece 22 as a switch member made of a spring material such as phosphor bronze is welded to the tip thereof with solder or the like. An insulating tube 23 is attached to this welded portion, and the insulating tube 23 maintains a substantially parallel constant gap between the section 22 and the upper electrode of the battery 13, thereby forming a switch means. The other lead terminal 24 is provided with an insulating coating as necessary and is connected to the lower electrode of the battery 13. The main body consisting of the light emitting diode 12 and battery 13 formed in this way is inserted into the case 11 while pushing out the insertion piece 1ick around the opening 16, and the light emitting diode 1 is inserted into the case 11.
2 is inserted into the housing portion 11a so that the tip end thereof faces the through window 15 (6).

A method of using the embodiment configured as described above will be explained. Without twisting, the key 14 is inserted into the opening 16 and the opening 17 from the tip of the leg 14b in this order, and the key 14 is held in the case 11 by attaching the head 14a while pushing out the insertion piece 11c. Next, when the case 11 is held between fingers and the top is pressed all the way down, the section 22 is bent and its tip comes into contact with the upper electrode, thereby closing the switch means. As a result, light is emitted from the light emitting diode 12. Since the direction of this light matches the extending direction of the healthy leg portion 14b, the desired keyhole vicinity is naturally irradiated, and the healthy leg portion 14b can be easily guided and inserted into the keyhole. .

As mentioned above, according to this embodiment, the light-emitting elements are a small, thin, high-capacity lithium battery and a light-emitting diode, which is also small and suitable for localized irradiation and has low power consumption, so that the lifespan is shortened. It is possible to reduce the size and weight without damaging the structure.

In line with this, the key can be attached and integrated into the case of the main body, the direction in which the healthy leg extends and the direction of light irradiation match, and the light can be emitted simply by pressing the top of the case with your fingertip. It is extremely easy to operate with one hand, and usability can be significantly improved.

Furthermore, since the light can be made to blink simply by adjusting the pressing force of the fingertip, and the continuous lighting time can be minimized, the battery life can be further extended.

Note that the present invention is not limited to the above embodiments,
For example, it also includes configurations as described below.

First, in order to effectively emit the light generated by the light emitting diode 12 to the outside of the case 11, a metal cylinder 25 with a glossy inner surface coated with chrome plating or the like as shown in FIG. It is desirable to cover the outer circumference of the head. Also, instead of this, a light emitting diode 12
Even if the outer periphery of the head is directly plated with a shiny metal, etc., the effect will be the same.

Further, even if a coil formed from a spring member is applied to the section 22, the same effect can be obtained.

Furthermore, the insertion piece 11c that holds the key head 14a is
The insertion piece lid may have the shape shown in FIG. 5, which has the effect of making it easier to attach and detach the main body and the key.

Furthermore, as shown in FIG. 6, by fully forming protrusions 26 at appropriate locations on the inner surface of the boundary between the storage portion 11a and the key mounting portion 11b, the fit of the main body can be improved.

〔Effect of the invention〕

As explained above, according to the present invention, the device can be made small, lightweight, and easy to use.
