Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a lighting fixture suitable for illuminating a keyhole.

[Conventional technology]

When attempting to insert a key into a keyhole, it is often inconvenient to locate the keyhole because it is dark, such as at night. 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,
It consists of two 1.5V dry batteries facing a window 2 opened at the periphery of the case 1, a slide switch 4 formed on the top surface of the case 1, and a chain 5 to which a key is locked. ing.

[Problem that the invention attempts to solve]

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 its large size, it is difficult to insert the key while illuminating the keyhole with one hand, so it must be operated with both hands, making it extremely inconvenient to use.

Furthermore, as shown in Japanese Utility Model Publication No. 36-24199, there is a known case in which a key is integrally attached to a case incorporating an illumination lamp, but the key and case can be rotated via a pivot. Since it is possible to engage, special processing is required for engagement, and it cannot be easily used with keys that have a key head like those on the market, and it is not versatile. I had a problem with it missing. Moreover, there is a risk that the key portion may rotate during use, and the irradiation direction of the illumination lamp may deviate from the direction in which the key extends, making it difficult to guide the key into the keyhole, resulting in poor usability.

On the other hand, Utility Model Application Publication No. 53-126887 discloses a key case with a lighting fixture attached to it, but the relative relationship between the key and the lighting fixture is not fixed, so it can be used freely. Since the relative positions change and the direction in which the push button switch is operated is orthogonal to the direction in which the key is held, there is a problem in that it is extremely difficult to operate the key while the light is on at the same time.

Further, Japanese Patent Application Laid-Open No. 55-26397 proposes a key that is fixed to a light case using an adhesive layer or an adhesive. However, with adhesive layers, the key may shift due to the force applied when operating the key.
There is a problem with peeling, making it difficult to use. On the other hand, the problem with adhesive keys is that once they are fixed, they cannot be replaced with other keys, and additional adhesive is required, which is inconvenient. Furthermore, there are problems in that the configuration is complicated, the number of parts is large, and the number of manufacturing steps is required.

The purpose of the present invention is to solve the above-mentioned drawbacks of the conventional technology.In other words, it is versatile enough to be firmly attached to various keys on the market without special processing or tools, and can be used with one hand. To provide a lighting fixture for a keyhole which is convenient for use, is small and lightweight, and is easy to use.

[Means for solving problems]

In order to achieve the above object, the present invention includes a main body comprising a disc-shaped battery and a light emitting element placed on the top surface of the battery and connected to the battery via a switch means, and a main body that is attached to the main body. The housing comprises a storage part and a case having a key attachment part formed on the lower surface of the storage part, the case is integrally formed of an elastic resin material, and the storage part is formed on the lower surface of the storage part. a flange for holding the battery by locking a lower peripheral edge of the battery is formed on the inner peripheral surface of the opening, and a through window is formed in the side wall of the storage portion facing the tip of the light emitting element. The key mounting part extends from the peripheral edge of the storage part so as to embrace at least the peripheral edge of the key head to be mounted, and is opposed to the collar with a certain gap. An opening through which a key leg can be inserted is formed in a peripheral wall that includes a locking piece and is located at a position corresponding to the through window. The battery is characterized in that it has a contact piece that is displaced by pressure, and the contact piece is formed and arranged so as to close a circuit between one lead terminal of the light emitting element and the top electrode of the battery.

[Effect]

By configuring it in this way, the key mounting part made of an elastic material is integrally formed on the lower surface of the main body storage part, and the key mounting part has a structure in which the head of the key is wrapped around the locking piece and the collar. Due to the elastic force of the locking piece, the collar, and the periphery, and the frictional force with the surface of the key head, the key and the entire case are connected with sufficient strength for practical use. It is integrally and firmly attached to the head, which is the gripping part.

Furthermore, when operating the key, the user must grasp the case by placing the thumb and index finger on the top and bottom surfaces of the case, respectively, and the case is made of an elastic material, and the switch means closes by applying a pressing force to the top of the case. Because of this structure, the light emitting element is irradiated by simply increasing the gripping force, and the key operation and lighting operation can be performed at the same time with the same grip, making it extremely easy to use. can get.

Moreover, since the opening through which the key leg is inserted is provided in accordance with the position of the through-hole through which the light is emitted,
Light is necessarily irradiated along the extending direction of the key leg, and the area around the keyhole is automatically illuminated when the key is operated. Also, this means that
The above-mentioned key and the entire case are firmly and integrally connected to each other, so that the guarantee is further ensured.

In addition, since the connection with the key is removable,
It can be attached to various commercially available keys without any modification or use of tools. Moreover, the entire key mounting part has elastic force and frictional force also contributes to key retention, so it can be used even when the dimensions of the key mounting part and the external dimensions of the key head are slightly different, making it versatile. can be satisfied.

〔Example〕

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, FIG. 3 shows an external perspective view, and FIG. 4 shows an internal perspective view.

In these figures, a case 11 is integrally formed of an elastic member such as rubber or synthetic resin (e.g. thermoplastic polyurethane elastomer, manufactured by Nippon Elastolan Co., Ltd.), into which a main body consisting of a light emitting diode 12 and a battery 13 is inserted. storage section 11a
and a key mounting part 1 into which the head 14a of the key 14 is inserted.
1b. A through window 15 is formed in the peripheral wall surface of the storage portion 11a. Key attachment part 11b
An opening 1 through which the main body can be inserted is provided in the center of the bottom surface of the
6 is formed, and the leg part 14 of the key 14 is formed on the bottom periphery.
An opening 17 through which the head 14b is penetrated and an opening 18 through which the peripheral protrusion of the head 14a can protrude are formed. The remaining portion of the bottom surface formed in this manner serves as a locking piece portion 11c that holds the key head 14a.
Additionally, a collar 26 is formed at an appropriate location on the inner surface of the boundary between the storage portion 11a and the key mounting portion 11b, thereby improving the fit of the main body and the key. opening 1
7 and the through window 15 are formed around the same position in the circumferential direction of the case 11. Note that 19 is a hole for locking a chain such as a key chain (not shown).

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 serve as 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, it is desirable to fix the light emitting diode 12 to the upper surface of the battery 11 with the adhesive 20. One lead terminal 21 of the light emitting diode 12 is cut short, and a contact piece 22 as a switch member made of a spring material such as phosphor bronze is welded to the tip of the lead terminal 21 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 contact piece 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 composed of the light emitting diode 12 and the battery 13 formed in this way is attached to the engaging piece 1 around the opening 16 described above.
1c is inserted into the case 11 while pushing it apart,
The light emitting diode 12 is inserted into the storage part 11a so that the tip thereof faces the through window 15.

The operation of the embodiment configured in this way will be explained. First, insert the key 14 from the tip of the leg 14b into the opening 16 and the opening 17 in this order, and then
It is held in the case 11 by attaching the head 14a while pushing it apart. Next, case 11
When you pinch the top part with your fingers and press down, the contact piece 22
is bent and its tip comes into contact with the upper surface 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 key leg 14b, the desired keyhole area is naturally illuminated, and the key leg 14b can be easily guided and inserted into the keyhole. I can do it.

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

In line with this, a key mounting part made of an elastic material is integrally formed on the bottom surface of the main case, and the key mounting part is structured so that the head of the key is wrapped around the locking piece and the collar, so that these Due to the elastic force of the piece, the collar, and the periphery, and the frictional force with the surface of the key head, the entire key and case are connected with sufficient strength for practical use. It can be integrally and firmly attached to the

In addition, the extension direction of the key leg portion and the light irradiation direction must be made to match, and the case must be made of an elastic material, and the switch means must be configured to close when a pressing force is applied to the top of the case. Therefore, the light emitting element will be illuminated by simply increasing the gripping force in the same posture as the key operation. Therefore, the key operation and the lighting operation can be performed at the same time with only one hand in the same grip state, resulting in extremely convenient use.

Moreover, since the opening through which the key leg is inserted is provided in accordance with the position of the through window from which the light is emitted, the light is irradiated in accordance with the extending direction of the key leg. The area around the keyhole is automatically illuminated as the key is operated, and this is further ensured by the fact that the key and the entire case are firmly connected together.

In addition, since the connection with the key is made to be removable using the elastic force of the case, it can be attached to various commercially available keys without special processing or tools, and the entire key attachment part can be attached. Because it has elasticity and frictional force also contributes to key retention, it can be used even when the dimensions of the key attachment part and the external dimensions of the key head are slightly different, making it highly versatile and practical. ing.

In addition, switch parts such as push buttons are no longer required.
The structure is simple and compact, and mechanical failures can be reduced.

In addition, when inserting the main body such as a battery into the storage part, the opening on the lower surface of the storage part is widened and inserted/removed, so parts for fixing the battery etc. are not required, and the configuration can be extremely simplified.

Furthermore, since the outer surface is elastic, there is no risk of damaging the inside of clothing pockets or handbags.

In addition, it is possible to easily reduce the number of lights by simply adjusting the pressing force of the fingertip, and the continuous lighting time can be minimized, which has the effect of further extending the life of the battery.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but also includes configurations as described below, for example.

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

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

Further, a locking piece 1 that holds the key head 14a is provided.
1c may be a locking piece 11d having the shape shown in FIG. 6, which has the effect of making it easier to attach and detach the main body and the key.

[Effect of idea]

As explained above, according to the present invention, it is possible to securely and integrally attach to various commercially available keys without using any special processing or tools, and to have versatility. Operation and key operation can be performed at the same time with the same grip, and the area around the keyhole is automatically illuminated, making it convenient to use with one hand, improving usability, and reducing manufacturing man-hours due to its small size and light weight. It can be made into something.
