DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a key in which a metal key plate material is covered with a synthetic resin photographic plate, and more particularly, the present invention relates to an unprocessed duplicate key called a "key blank". For key material.

[0002]

2. Description of the Related Art Conventionally, as a key of this kind, a mold type in which a synthetic resin material is molded on a photographing portion of a key board material to form a photographing plate, and a synthetic resin is formed on both sides of the photographing portion of the key board material. There are an adhesive type in which a photographic plate is formed by bonding plates, and a press-fit type in which a photographic portion of a key board material is press-fitted into an insertion hole provided in an end surface of a synthetic resin photographic plate.

[0003]

However, the mold type requires a lot of trouble and cost to form the photographic plate, and is not suitable as a key material for a duplicate key. In the adhesive type, the synthetic resin plate is easily peeled from the photographed portion of the key board material, and the photographing plate may be damaged. With the press-fit type, not only is it time-consuming to attach the shooting plate to the shooting portion of the key board material, but also when the strong tension acts between the shooting plate and the key board material, the shooting portion of the key board material shoots. There is a risk of falling out of the plate.

When a plurality of duplicate keys are produced to distinguish holders, it is necessary to put a mark for each holder on the photographing plate of each duplicate key, but the work of attaching such a mark is complicated. There are also problems such as the drop off of the attached mark.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problem, and is provided with a synthetic resin photographic plate having a retaining structure attached to a photographic portion of a metal key plate material. An object of the present invention is to provide a key that can be easily mounted on a shooting plate and does not cause the shooting plate to fall off. Another object of the present invention is to devise a combination of colors of each member constituting the photographing plate, thereby eliminating the need for a work of attaching a mark and a problem that does not cause a problem that the mark is dropped off. The point is to provide.

[0006]

A key according to the present invention comprises a metal key plate having a photographing portion, and a synthetic resin photographing plate which covers the photographing portion of the key plate material. The shooting plate is
A cover plate portion having an insertion hole into which the shooting portion of the key board material is inserted, and a holding plate portion for holding the shooting portion inserted in the insertion hole of the cover plate portion. Notches are formed in the cover plate to expose both side surfaces of the inserted photographing unit, and the holding plate is fitted in the notch of the cover plate to fit the photographing. A pair of side plate portions that cover the exposed side surfaces of the portion are provided to face each other. An engagement portion is formed between each side plate portion of the holding plate portion and both exposed side surfaces of the photographing portion.

The key in the illustrated example indicates a key in a state before cutting a key pile, that is, a key material for a duplicate key called a key blank, but the key in the present invention is not limited to such an unprocessed key material. Needless to say, the concept includes the key after cutting.

The key is made of a metal key plate 1 having a photographing section 2 and an AB which is covered by the photographing section 2 of the key plate 1.
It is composed of a taking plate 10 made of a synthetic resin such as S or polypropylene. The key plate 1 is formed by integrally forming a key piece 3 having a key ridge cut at a side edge and the photographing portion 2 at a base end of the key piece 3. The taking section 2 has a substantially rectangular planar shape, and its width is slightly larger than the width of the key piece 3.
The photographing section 2 has a small width section 2b formed at a base end of a main body section 2a via a step section 6. As shown in FIGS. 3 and 4, a rectangular engaging hole 4 which is long in the width direction is provided substantially at the center of the plate surface of the photographing unit 2, and a square for mounting a key holder is provided at the base end. Each of the rectangular mounting holes 5 is opened through the plate surface.

The taking plate 10 includes a cover plate portion 20 and a holding plate portion 30. The cover plate portion 20 includes a front side portion 2
Opposite side portions 22, 22 are integrally formed at both ends of the first member 1. As shown in FIGS. 5 and 6, an insertion hole 23 having an opening surface conforming to the cross-sectional shape of the main body portion 2 a of the photographing portion 2 of the key board material 1 penetrates the front side portion 21 in the length direction. It is formed. In the insertion hole 23, the key board material 1 is inserted.
Is inserted. Guide grooves 24, 24 with which both end edges of the main body 2a of the photographing section 2 are slidably engaged are formed on the inner surface of each side 22. One end of the groove bottom of each guide groove 24, 24 is continuous with the insertion hole 23, and the other end is located in the middle of the side portion 22.

The cover plate 20 has side portions 22, 22.
There is a notch 25 between them. The notch 25 is for exposing both side surfaces of the photographing portion 2 when the photographing portion 2 of the key board material 1 is inserted through the insertion hole 23 of the cover plate portion 20. The size is set so that 4 and mounting hole 5 are located in notch 25.

As shown in FIGS. 3 and 7, the holding plate portion 30 has a pair of opposed side plate portions 31, 31. One end of each of the side plate portions 31, 31 is integrally connected, and the other end is connected. It is open. Each side plate portion 31 has a shape adapted to the notch portion 25 of the cover plate portion 20, and fits into the notch portion 25 to close the exposed both side surfaces of the photographing portion 2 of the key board material 1. At each side plate portion 31, a mounting hole 32 having the same shape as the mounting hole 5 is formed at a position corresponding to the mounting hole 5 of the photographing portion 2.
