DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card which doubles as a key for locking a key for locking a door of a passenger car or a house, other doors, a storage, or the like, or a spare key for convenient carrying.

[0002]

2. Description of the Related Art Heretofore, as a card also serving as a key holder of this kind, there have been those shown in Japanese Utility Model Laid-Open No. 63-169668 and Japanese Utility Model Laid-Open No. 63-41282.

In the former, as shown in FIG. 3, a notch 7 having substantially the same shape as the key 5 is formed from the outer periphery of the card 6 toward the center, and both sides 7a, 7a of the notch 7 and the key 5 are formed. The key 5 is attached so as to rotate in the direction perpendicular to the card surface.

In the latter case, as shown in FIG.
Of the card 10 is formed on the surface of the card 10 so as to cover the lower half of the recess 11.
The key 9 connected to the key 11 is inserted between the recess 11 and the thin plate 13. At a position corresponding to the key head of the recess 11, a through hole 12 for extracting a key is provided. Has been drilled.

[0005]

The above-mentioned conventional card which also functions as a key holder, the one shown in FIG. 3, requires that the side surface of the card and the side surface of the key be connected by pins, which makes assembly processing difficult. In addition, there is a problem that the strength of the connecting portion is not sufficient due to the fact that both sides of the cutout portion are easily bent or expanded. Also, in this card, the key is attached with a pin so that it can rotate in the vertical direction with respect to the card surface, so there is a risk that the key may inadvertently jump out of the cutout of the card, There was a problem that required attention.

FIG. 4 shows a method in which a recess is formed in a card, and a through hole is formed in a predetermined position of the recess.
A thin plate must be attached to the upper surface of the lower half of the card, and the card and the key must be connected by a connecting cable. This has a problem that the number of manufacturing processes is large and the cost is increased. Further, in this card, since a thin plate is attached to the lower half of the upper surface of the card, the thickness of the card is further increased, and the thickness is not constant, so that it is not necessarily excellent in portability. Was.

[0007] It is an object of the present invention to solve the above-mentioned problems of the conventional card which also functions as a key ring.

[0008]

According to the present invention, in order to solve the above-mentioned problems, a concave portion having a shape substantially equal to the outer shape of a key is formed on a surface of a card formed of a synthetic resin plate having flexibility. Then, the key is mounted at a position corresponding to the key head in this recess so that it can rotate in a plane substantially parallel to the card with an axis passing through the head, and when carrying, the key pops out of the recess of the card When the card is bent, the key rotates around the axis and the tip of the key protrudes from one side of the card in a usable state.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a plan view showing an embodiment of a card serving also as a key holder according to the present invention, and FIG.
It is an X-ray sectional view. As shown in the drawing, the card 2 which also functions as the key holder of the present invention has a recess 2a having a shape substantially equal to the outer shape of the key 1 at a predetermined position on the surface, and a portion 2a corresponding to the key head 1b in the recess 2a. ′, A key 1 is attached so as to be rotatable about a shaft 3 penetrating the head 1b.

The card 2 is formed of a flexible synthetic resin plate.

A key 1 attached to the card 2
May be either a normal original key or a spare key, or may have only the general outline of the key so that the user can process it as a spare key after purchase.

As the shaft, bolts / nuts, eyelets, pins, etc. can be used, but it is desirable that the shaft be integrally crimped to the card so as not to loosen.

Next, a method of using the card having the above-mentioned structure which also functions as the key holder of the present invention will be described. First, in use, the card 2 itself is slightly bent, and the tip 1 of the key 1 is moved.
After floating a from the recess 2a, the side of the key 1 may be pushed from either the left or right. This allows key 1
Pivots horizontally (in a plane substantially parallel to the card 2) about the axis 3 in either the left or right direction, and the tip 1a of the key 1 is moved from one side of the outer periphery of the card 2 as shown by a chain line in FIG. Protrude.
Therefore, the key can be used in this state.

At this time, the key 1 is located on the periphery 2 of the recess 2a.
By riding on the key b, the elastic piece 1b 'provided at the rear end of the key 1 is pressed against the bottom surface of the recess 2a to press the key 1 against the peripheral edge 2b, whereby the key 1 is pulled out. It is held in the position.

In order to store the key 1, it is sufficient to push the side of the key 1 completely opposite to the above, whereby the key 1 is turned around the shaft 3 so that it is located above the recess 2a. When the key 1 comes, the key 1 is forcibly fitted into the recess 2a by the restoring force of the elastic piece 1b 'and the restoring force of the flexible card 2 itself. Key 1 in this way
As shown in the cross-sectional view of FIG. 2, the key 2 is stored in the recess 2a of the card 2 with substantially the same thickness as the card 2, and the card 2 is bent unless the tip 1a of the key 1 is pushed. Does not jump out of the recess 2a.

In the above description, a holder for accommodating one key 1 has been exemplified. However, a plurality of recesses 2a may be formed in the card 2 to accommodate, for example, a car key and an entrance door key at the same time. .

As described above, the card 2 which also serves as the key holder of the present invention can store the key 1 in a low volume, and can print and display various advertisements, patterns, explanations, and the like on the surface of the card 2 itself. It can be configured in a card or IC card to have a password function as various membership cards, or used as a transmitter of an electronic lock device for a wide range of uses.

In the illustrated example, the rear end of the key head 1b is divided into a plurality of parts to make the operation more reliable.
Although b ′ is provided, the same operation can be performed only by the elastic force of the flexible card 2 itself.
b 'need not necessarily be provided.

[0020]

As described above, the card which also serves as the key holder of the present invention is formed by forming a recess in a card made of a synthetic resin plate having flexibility, and the key is rotatably mounted in this recess. It is extremely easy to manufacture and can be manufactured at low cost.

The key is stored in a recess of the card,
Because it can be carried in a card form, it is easy to carry and it does not accidentally jump out of this recess when carrying, but when used it is fixed with the tip protruding from one side of the card Since it is held, it has an effect of being excellent in handling.
