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 taken out with a single touch from a case accommodating a normally used key.

[0002]

2. Description of the Related Art Usually, a hook is held on a double-opened leather key chain or a ring-shaped key chain. In addition, as an invention and a device that makes it possible to take out the stored key relatively easily (Japanese Utility Model Publication No. 47-4550), (Japanese Patent Laid-Open No. 63-272305), (Japanese Utility Model Publication No. 64-23218).
No.) etc. In these conventional techniques, it is necessary to select the key at any time to take out the intended key, which requires time and labor. Also, as an item that can be taken out with one touch (Japanese Patent Laid-Open No. 7-8
No. 8008), (Actual No. 63-202320), (Actual No. 3050621), etc. These conventional techniques have a complicated mechanism, a large number of parts, lack of reliability due to insufficient strength, etc., and have not been put to practical use.

[0003]

At present, most key chains are made of double-sided leather or ring-shaped key chains. When a plurality of keys are stored in them, it is necessary to select them at any time to take out the intended key. In addition, since the name is not written on the key itself, it is necessary to know where the key is used by the shape of the key.

Even if it is recognized, it takes time and labor to select and extract.

Further, the conventional technology which can be taken out by one-touch has a complicated mechanism, has a large number of parts, is large, lacks reliability due to insufficient strength, etc., and has not been put to practical use.

DISCLOSURE OF THE INVENTION The present invention provides a key holder which is simple in structure, has a small number of parts, and is compact, and at the same time is robust and highly reliable, with a 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, in which a large-diameter portion of a stepped pin is fitted in a recess of the head of the key to hold the key in a case. There is also an opening for swiveling out the desired key.

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

When the key is pivoted a little, the recessed position of the head also moves, the stepped pin cannot be returned to the original position, and the key can be freely pivoted and taken out for use.

When the key is used, the key is pivoted back into the case, and when it is pivoted to the position where it was originally stored, the large diameter portion of the stepped pin slides and is held and held in the recessed position of the head of the key. It

When the key is stored in the case, the stepped pin is sandwiched by the disk-shaped leaf springs from both outsides of the case, and always tries to stay in the case to keep the key held.

The key holder of the present invention has a key inserted directly into the pivot, and the thickness corresponding to the number of keys to be housed and the wall thickness of the case are the total thickness of the key holder, which is compact unlike the prior art. The head of the key is stable because both sides are restricted by another key or the inner surface of the case. Further, the main components are a case, a key, a pivot, a stepped pin, and a disk-shaped leaf spring.

BEST MODE FOR CARRYING OUT THE INVENTION 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 storage number of 2, and FIG. 6 shows a plan view of a key holder for a maximum storage number of 6. The key chain of the present invention is manufactured according to the required number, but for example, even if only 5 keys can be stored in the key holder for the maximum storage number of 6, a spacer having the same thickness as the shortage key can be inserted instead. It is possible to use any number up to the maximum storage number. Also, even a thin key can be used in the same way by inserting a shortage of spacers.

First, the key holder for the maximum number of two stored in FIG. 1 will be described. Two sets of keys 2 having the same recessed position on the head are assembled into the case 1 through the swivel shaft 3. The swivel shaft 3 is attached from both sides of the case together with a disc-shaped leaf spring 5 by means of a round machine screw 6. Has been. When the key is housed, the large diameter part of the stepped pin 4 is located in the middle part of the two keys as shown in FIG. 4 to hold the key. 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 desired key is swiveled out (the key can be selected by pressing the stepped pin). When the key 2 is stored in the case 1,
The stepped pin 4 is sandwiched by the disk-shaped leaf springs 5 from both outer sides of the case, and always tries to stay in the case to keep the key 2 held.

Next, the key chain for the maximum number of 6 stored in FIG. 6 will be described. Basically, it is the same as the key holder for the maximum storage number of 2 and the key 2 has the same recessed position on the head. As a set, 3 sets with 6 different recessed positions are stored. This is a product in which three parts with different positions of the large diameter part are incorporated. The disk-shaped leaf spring 5 for positioning the stepped pin is also used.

FIG. 6 shows a product with a light in which the light emitting diode 7 is incorporated. Further, a spacer 10 is incorporated which is inserted when the key is removed from the holder. Further, a leaf spring 9 for pushing out is attached to facilitate the removal of the key. A spring may be provided between the pivot and the key as the spring.

FIG. 8 shows an example in which identification marks and names of keys stored on the surface of the stepped pin or the case are described (the maximum number of storage is 6 and the same identification can be described on the back side).

By the way, the present invention is not limited to the above embodiment. There is no limit to the maximum number of items that can be stored, and by making the large diameter part of the stepped pin and the key head depression small and increasing the number of stepped pins, it is possible to manufacture any number of steps. The shape, material, design, identification mark, etc. of the case can be changed as appropriate.

[0019]

The present invention is a key holder with a simple structure, compact size, robustness, and high reliability. Also, when you take out the target key from the key chain, you can remove the target key with one touch by the identification mark or name on the case surface, so you can easily select the target key even if it is used by multiple people or even the lock that you do not normally use, Can be used.
