Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a key and a case in which an arbitrary key can be easily taken out of a case in which a commonly used key is stored.

[0002]

2. Description of the Related Art Usually, a hook is held by a double-sided leather key ring or a ring-shaped key ring. Further, as inventions and devices that make it easier to take out stored keys (Japanese Utility Model Publication No. 47-4550), Japanese Patent Application Laid-Open No. 63-272305, and Japanese Utility Model Application Publication No. 64-23218.
No.). In these prior arts, it is necessary to select at any time in order to take out a target key, which requires time and labor. In addition, as a product that can be taken out with one touch (Japanese Unexamined Patent Publication No.
No. 8008), (Japanese Utility Model Application Laid-Open No. 63-202320), and (Japanese Utility Model No. 3050621). These prior arts have a complicated mechanism and a large number of parts, are poor in reliability due to insufficient strength, and are not practically used.

[0003]

At present, most of the key holders are made of double-leafed leather or ring-shaped key holders. When a plurality of keys are stored in them, it is necessary to select the keys at any time in order to take out the desired key. Also, since no name is described on the key itself, it is necessary to know where the key is to be used in the shape of the key.

[0004] Even if it is recognized, it takes time and effort to select and extract.

[0005] In addition, the conventional technology which can be taken out with one touch has a complicated mechanism, a large number of parts, is large, lacks strength and has poor reliability, and is not widely used.

[0006]

SUMMARY OF THE INVENTION The present invention aims at providing a key ring which is simple in structure, has a small number of parts, is compact, and is robust and highly reliable, with a primary focus on being able to be taken out with one touch.

FIG. 1 is a plan view of a key holder for storing two keys. A large diameter portion of a stepped pin fits into a recess in the head of the key, and the key is held in a case. There is also an opening for swirling and removing the target key.

When the key is taken out and used, the stepped pin is pushed from the outside, and the large diameter portion of the stepped pin is slid out of the head recessed position of the key, and at the same time, the small diameter portion is moved to the head recessed position of the key. And the key can be turned and taken out.

When the key is slightly turned, the recessed position of the head also moves, the stepped pin cannot be returned, and the key can be freely taken out and used.

When the key has been used, the key is turned back into the case. When the key is turned back to the originally stored position, the large-diameter portion of the stepped pin slides and is held in the recess of the head of the key. You.

[0011] When the key is stored in the case, the stepped pin is sandwiched between the outer sides of the case by the disc-shaped leaf springs, and always tries to stay in the case, thereby keeping the key held.

In the key holder of the present invention, the key is inserted directly into the turning shaft, and the thickness of the key holder is equal to the number of keys to be stored and the thickness of the case is the entire thickness of the key holder, which is different from the prior art and is compact. The key head is stable because both sides are regulated by another key or the inner surface of the case. Furthermore, since the main components are simple structures including only a case, a key, a rotating shaft, a stepped pin, and a disc-shaped leaf spring, the key holder is highly reliable.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a plan view of a key holder for a maximum of two storage units, and FIG. 6 shows a plan view of a key holder for a maximum of six storage units. The key ring of the present invention is manufactured according to the required number. For example, even when only five key rings are stored with a key ring for a maximum storage of six, a spacer having the same thickness as the insufficient key is inserted instead. Any number below the maximum storage number can be used. Also, a thin key can be used in the same way as when a short spacer is inserted.

First, a description will be given of a key holder for a maximum storage number of two shown in FIG. A set of two keys 2 having the same recessed portion at the head is assembled into the case 1 through the turning shaft 3. The turning shaft 3 is attached from both sides of the case together with a disc-shaped leaf spring 5 by a round screw 6. Have been. When the keys are stored, the large diameter portion of the stepped pin 4 is located in the middle of the two keys as shown in FIG. 4, and holds the keys. On the other hand, at the time of taking out, as shown in FIG. 5, the stepped pin 4 is slid to move the small diameter portion to the position of the key to be taken out, and the target key is turned and taken out (the key can be selected in the direction in which the stepped pin is pushed). When the key 2 is stored in the case 1,
The stepped pin 4 is sandwiched from both outer sides of the case by the disc-shaped leaf springs 5 and always tries to stay in the case, and keeps the key 2 held.

Next, a description will be given of the key holder for a maximum of six storage units shown in FIG. Basically, it is the same as a key holder for a maximum of two storage units. The key 2 has the same head depression position as two sets, and three sets of six depressions with different depression positions are stored. This is a product in which three large diameter portions having different positions are incorporated. The disc-shaped leaf spring 5 for positioning the stepped pin is shared.

FIG. 6 shows a light-equipped device incorporating the light-emitting diode 7. Also, a spacer 10 is inserted to replace the key when it is removed from the holder. Further, a push-out leaf spring 9 is attached to facilitate the key removal. The spring may be provided with a spring or the like between the pivot shaft and the key.

FIG. 8 shows an example in which the identification marks and names of the keys housed on the stepped pins and the case surface are described.

The present invention is not limited to the above embodiment. There is no limitation on the maximum number of stowed pins, and it is possible to manufacture any number of pins by reducing the large-diameter portion of the stepped pin and the depression of the key head and increasing the number of stepped pins. The shape, material, design, identification mark, etc. of the case can be changed as appropriate.

[0019]

According to the present invention, a key holder having a simple structure, a compact structure, a robust structure, and a high reliability is provided. Also, when taking out the target key from the key ring, the target key can be taken out with one touch by the identification mark or name on the case surface, so that the target key can be easily selected even when used by a plurality of people or a lock that is not used regularly, Can be used.
