Description

[Detailed explanation of the invention] (a) Purpose of the invention In conventional keychains, the leather or vinyl cover that covers the key gets damaged due to wear, and the cover is made to stay in place with a hook, so the hook becomes uneven and makes it difficult to carry around. It was inconvenient. In addition, since the joint fixing parts are all in one place, when removing the key, the chain and ring get tangled and it takes time even if you use both hands, and the chain and ring to attach the key have to be thick and large. As the number of keys stored increased, the thickness increased, and the chain and ring became uneven, making it bulky and inconvenient to carry around or put in your pocket.

As for the opening/closing key case, the main body of the case that stores the keys is simply a series of rectangular cases, which creates unnecessary space when the keys are stored, and is wide compared to the number of keys to be stored. It was bulky and inconvenient. Also, since the flat lid is attached to the hinge in the center of the case, the lid gets in the way when you take the keys in and out, and since there is no lid on the side, the head of the stored key may stick out of the case. There were drawbacks such as dirt getting in. Furthermore, when storing several keys stacked on the fixed hook, in order to use the lower key, first remove the upper key from the fixed hook, then rotate the lower key around the fixed hook. It took a lot of effort to use both hands. In addition, since the key is fixed to the case and protrudes, the length of the key plus the case itself becomes an inconvenience when opening a drawer or door of a desk, library, etc. In particular, when used as a car key, the width of the case and the length of the key protrude, resulting in drawbacks such as getting in the way of driving operations and lacking in safety.

(b) Means for solving the problem This proposal was completed with the aim of eliminating the above-mentioned drawbacks.
It is divided into two parts, like the almost triangular key storage compartments 3 and 4, and the lids 5 and 6 are integrated with the sides that open diagonally.
joint fixing parts 7, 8 and 9, 10 are provided dispersedly at the ends of the key storage parts 3, 4, and the joint fixing parts and a rotatable chain 11 having a thickness within the thickness of one key are provided. , 12, 13, and 14, and attach a key to the end of the chain. In this state, store the key in the case and close the lid.

To use the key, open the lid by sliding the buttons 19 and 20 on the side, take the key out of the case as shown in Fig. Adding chain 14, the 6th
It is a metal case-shaped key chain that is used with the lid closed as shown in the picture.

(c) Action and effect of the invention This powder is composed as described above,
By attaching the integrated lids 5 and 6 with diagonal double-sided doors, there is no need for covers or hooks made of leather, vinyl, etc., and there is no unevenness or bulk, and since the double-sided doors allow you to take in and take out keys, they do not get in the way. Not only is it time-saving, the lid is integrated into the side, so the head of the key won't come out of the case.
I couldn't even get any garbage in. In addition, the key storage parts 3, 4
Since it is shaped like a nearly triangular key, unnecessary space is eliminated, making it more compact.Furthermore, the joint fixing parts 7, 8 and 9, 10 are separated, so there is no need for chains or keys to get tangled, making it more convenient. Summer. In addition, the rotatable chains 11, 12, 13, and 14 to which the keys are attached are also made to have a thickness within the thickness of one key, so they are not bulky and thin compared to the number of keys stored, making them easy to handle and easy to carry around or carry in your pocket. It was convenient because it didn't get uneven even if I put it in the bag. Furthermore, since it is made of metal, it is durable and won't break like leather or vinyl. Figures 1 to 6 show the key storage parts 3 and 4.
It is designed to be able to store two keys each, for a total of four keys, and it is also possible to increase the number of keys that can be stored by making the case body deeper.

As described above, this case-type key chain is extremely convenient for using keys for cars, desks, archives, etc. as it is thin and easy to carry, and keys can be easily put in and taken out with one hand. Although the structure of the present invention is relatively simple, it is novel as a key chain and has great practicality.

Claims (1)

[Scope of utility model registration request] The case body 1 is diagonally divided into two key storage areas 3 and 4 by a partition plate 2, and lids 5 and 6 with integrated diagonal double-sided sides are attached, and joints are fixed to both ends of the key storage areas 3 and 4. Rotatable chains 11, 12 and 13, 14, each having parts 7, 8 and 9, 10 separated and having a thickness within the thickness of one key, are connected to the respective joint fixing parts, so that the key can be freely rotated. Attach it to the end of the chain. Store it in the case in this state.
To use the key, open the lid, take out the desired key from the case, fit the rotatable chain with the key into either of the side cut portions 15, 16 or 17, 18 of the lid, and then close the lid. A metal case-shaped key chain that is used when closed, is thin and easy to carry, and allows you to easily insert and remove keys with one hand.
