Abstract

PURPOSE: A key equipped with a lamp is provided to allow a user to easy open a lock by using a key in a dark place without using a separate illumination unit by integrally forming the lamp with the key. CONSTITUTION: A key includes handle sections(2,3), in which a battery and an electric bulb(5) are accommodated. A neck section(1) is provided between a key section and the handle sections(2,3) through an insert molding process. The neck section(1) transfers light generated from the electric bulb(5). The handle sections(2,3) are made of plastic material. After accommodating the battery and the electric bulb(5) in the handle sections(2,3), the handle sections(2,3) are coupled to each other by means of a bolt(8). A switch(4) is provided on the handle sections(2,3) in order to turn on/off the electric bulb(5).

Description

Key Cimbined With Light}

The present invention relates to a light combination key, and more particularly, a battery (6) and a light bulb (5) built in the key handle (2) (3) is built in the key handle without the need for additional lighting at night or in the dark ( 2) (3) has a built-in light bulb (5) to make it easy to find the keyhole.

Conventionally used keys are inconvenient to find a keyhole at night or in a dark place without the need for additional lighting.

The object of the present invention is to inset the injection molding (1) of various metal keys with a transparent plastic, and then completed the combination of the key handle (2) (3) in which the battery (6) and the bulb (5) is built, so at night or in dark places The key is to provide a light combination key that makes it easy to find the keyhole by using the light of the bulb (5) inside the key handle (2) (3) when opening the key.

According to the present invention, a battery (6) and a light bulb (5) are embedded in a key handle (2) (3) used for a building door or a lock, including a car key, thereby switching the switch (4) on the key handle (2) (3). A light dual key is provided which can be pressed to obtain a light bulb (5).

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

Figure 3 is a cross-sectional view showing a combination key of the electric light key having the battery 6 and the bulb 5 in the key handle (2) (3) according to the present invention as follows.

Fig. 4A is a product in which injection molding 1 is made of transparent plastic on various metal keys, and serves as a light effect of delivering light to the bulb 5.

4 (B) and (C) are key handle cases (2) and (3) injection-molded with plastic, and (D) (battery, light bulb, conduction spring) of FIG. 4 in (B) and (C) of FIG. After the built-in metal steel plate (switch), assembled with a coupling bolt (8) together with Figure 4 (A) to complete the key for the light.

In addition, various three-dimensional designs can be envisioned on the surface of the molded key handle (2) and (3), thereby improving the appearance of the key handle (2) and (3) in various types.

The light dual key can eliminate inconvenience by using a light bulb (5) light in the light dual key handle (2) (3) without the need for additional illumination in using the key at night or in a dark place.

As described above, according to the present invention, when using a key at night or in a dark place, the keyhole is conveniently used by using the light of the light bulb (5) built in the electric key holder (2) (3) for dual use without the need for additional illumination. Can provide a light key that can be found.

Claims (1)

After the car keys, various metal keys needed for building doors and locks were inset injection molded with transparent plastic (1), and then combined with the key handles (2) and (3) with a battery (6) and a light bulb (5). A light dual key, characterized in that when the switch (4) is pressed on the key handle (2) (3), the light is illuminated on the light bulb (5) embedded in the key handle (2) (3).
