Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door having a keyhole display function capable of illuminating and displaying a keyhole provided in the door.

[0002]

2. Description of the Related Art Conventionally, in a door equipped with a locking device,
The keyhole is arranged so as to be exposed on the outer surface of the door, and when the door is opened to enter the building, the key is inserted into the keyhole and unlocked to open the door.

[0003]

However, since the keyhole provided on the outer surface of the door is always visible in the daytime, the key can be inserted into the keyhole without any problem, but when it is dark like midnight. Had a problem that the position of the keyhole was difficult to understand and it took time to insert the key into the keyhole.

SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned problems, and the keyhole can be easily inserted without checking the position of the keyhole and checking the position of the keyhole even if it is dark at night. It aims to provide a door with a display function.

[0005]

According to the present invention, in order to achieve the above object, a lock device in which a keyhole illuminator 3 is attached to the outer surface of a door 2 having a lock device 1 and is exposed on the outer surface of the door 2. The keyhole 4 of No. 1 is arranged in the keyhole lighting tube 5 provided in the keyhole lighting tool 3, and the light emitting portion 7 which emits light by using the solar cell 6 provided in the keyhole lighting tool 3 as a power source is provided at the tip of the keyhole lighting tube 5. It is provided.

[0006]

By illuminating the keyhole 4 by the light emitting portion 7, the position of the keyhole 4 can be easily confirmed even in the dark at night, and it is troublesome to insert the key into the keyhole 4. Can be done easily without. Moreover,
Since the light emitting section 7 emits light using the solar cell 6 as a power source, it is not necessary to separately provide power wiring.

[0007]

The present invention will be described below in detail with reference to the illustrated embodiments. A door with a keyhole display function as shown in FIG. 1 is formed by attaching a keyhole illuminator 3 to a door 2 equipped with a lock device 1. As shown in FIG. 2, the keyhole illuminator 3 is mainly composed of a thin box-shaped mounting case 3a,
The mounting case 3a is provided with a solar cell 6, a keyhole illumination cylinder 5, and a power storage unit 8, respectively. The solar cell 6 is provided on the outer surface of the upper portion of the mounting case 3a, and the power storage unit 8 is provided on the inner surface side of the mounting case 3a so as to be located on the back side of the solar cell 6. It is designed to store electric power. The keyhole illumination tube 5 is a mounting case 3a
Is integrally provided so as to project outward from the outer surface, and a light emitting portion 7 that emits light by electric power supplied from the power storage portion 8 is provided at the tip edge. Reference numeral 9 is a through hole into which the fixing device 10 is inserted when the keyhole lighting device 3 is attached to the door 2 with the fixing device 10 such as a wood screw.

The keyhole illuminator 3 is attached to the outer surface of the door 2 as shown in FIG. 3 to form a door with a keyhole display function. The mounting is performed by positioning the keyhole 4 of the lock device 1 provided on the door 2 in the keyhole illumination tube 5.
It can be easily attached by disposing a on the outer surface of the door 2 and screwing the fastener 10 into the face plate 2a of the door 2. Here, since the solar cell 6 and the power storage unit 8 are provided in advance in the mounting case 3a, the mounting case 3a can be easily mounted to the door 2
It can be attached to various doors 2 equipped with the locking device 1 regardless of the door thickness.

Electric power is stored in the storage unit 8 by the solar cell 6 during the daytime, and at night time, the light emitting unit 7 emits light by the power supplied from the storage unit 8 to illuminate the vicinity of the keyhole 4. The position of the keyhole 4 can be easily confirmed even in a dark place such as at night, and the key can be easily inserted into the keyhole 4 without any trouble. Further, since the light source 7 is powered by the solar cell 6 which is integrally provided in the mounting case 3a that constitutes the keyhole lighting device 3, it is not necessary to separately provide power wiring.

In the embodiment described above, the mounting case 3
Although the attachment of a is performed by the fastener 10 such as a wood screw, the attachment is not limited to this and may be performed by a double-sided tape or an adhesive.

[0011]

As described above, according to the present invention, the keyhole illuminator is attached to the outer surface of the door provided with the lock device, and the keyhole of the lock device exposed on the outer surface of the door is provided in the keyhole illuminator. Since the light emitting part, which is placed inside the cylinder and uses the solar cell provided in the keyhole illuminator as a power source to emit light, is provided at the tip of the keyhole illuminating cylinder, the keyhole is illuminated by the light emitting part so that it is dark like at night. Even in such a case, the position of the keyhole can be easily confirmed, and the key can be easily inserted into the keyhole without time and effort. Moreover, since the light emitting portion emits light using the solar cell as a power source, it is not necessary to separately perform power wiring.
