[Problems to be Solved by the Invention] In a conventional key holder of this kind, there is not much problem when a normal key is used, but in a case of a building structure in which a large number of keys are used, for example, in a building or a school. When a large number of keys are stored in a bundled state, there is a risk that a person who tries to possess the key illegally removes the key and makes a spare key, but it will not be known, and the specific key of the key bundle However, there is a problem that even if the key is illegally extracted, the key keeper cannot immediately know that fact. For this reason, keys that must be prohibited from being copied must be individually managed using a lockable key storage box. However, a key storage box that stores individual keys must be installed. However, there is a problem that not only the cost is increased, but also the more keys to be managed, the larger the outer shape and a sufficient space for installing a storage box is required.

[Embodiment] An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a key holder according to the present invention, and FIG. 2 is an enlarged cross-sectional schematic view of a hollow cylindrical body constituting the present invention. In these figures, a key holder A according to the present invention includes a holder main body 1 having an opening 4 partially formed therein, and a hollow cylindrical body 11 screwed to the holder main body 1 to close the opening 4 of the holder main body 1. It is composed of this house,
The holder main body 1 is formed in a substantially loop shape by a metal rod body, and screw portions 2 and 3 are screwed at opposing ends of the open portion 4 of the holder main body 1. In this case, the screw portion 2 at one end is formed as a screw portion having a length approximately three times the length of the opening portion 4, and the screw portion 3 at the other end portion is formed as a screw portion having the same length as the opening portion 4. It is preferably formed as a part. The hollow cylindrical body 11 is formed of a soft metal, for example, brass, and has a female threaded portion 12 threaded on the hollow inner wall (see FIG. 2). Next, the case where the key whose copying is to be prevented is to be stored in the key holder A of the present invention will be described. When holding the key in the key holder, the hollow cylindrical body 11 is rotated to open the opening 4 of the holder main body 1 in the same manner as in a normal usage, and then the holder main body 4 is inserted into the through hole 21 of the key grip 20. Through. Then, the opening 4 of the holder main body 1 is closed by rotating the hollow cylindrical body 11 in the reverse direction. After the key is completely held in the key holder A, the portion corresponding to the open portion 4 covered by the hollow cylindrical body 11 is pressed and deformed by a tool such as pliers so that the plurality of held keys are not removed from the key holder A. .
The hollow cylindrical body 11 that has been pressed and deformed has the female screw portion 12 of the inner wall portion deformed inwardly to form a stopper 13, and the hollow cylindrical body 11 cannot rotate along the screw portions 2 and 3 of the holder body 1. . Thus, the opening 4 of the holder body 1 cannot be opened. In addition, the female thread 12 screwed to the threaded portions 2 and 3 of the holder body 1 tightens the threaded portions 2 and 3, and the holder body 1 and the hollow cylindrical body 11 are firmly connected.
Thus, the rotation of the hollow cylindrical body 11 becomes impossible, and unauthorized removal and insertion for duplicating the key bundled in the key holder is prevented. Cutting the key holder when removing the key from the key holder loses its function as a key holder, and the disconnection allows the administrator to easily visually confirm the unauthorized removal of the key, so that the key can be copied without being known to the administrator. Becomes impossible. In the above embodiment, the holder body 1 is formed so as to have the open portion 4. However, the open portion 4 is formed extremely narrow, and after rotating the hollow cylindrical body 11, both ends of the holder body 1 are pulled open. A similar effect can be obtained even if the key is attached to the hollow cylindrical body 11 together with the threaded portions 2 and 3 at both ends of the holder main body 1 by pressing.

[Effect of the Invention] The present invention is configured as described above, and according to the present invention, the following effects can be obtained. It is possible to prevent a specific key from being extracted from the key holder that bundles the keys, and if the key is extracted and an unauthorized copy is made, a part of the holder will be cut off. The custodian can know immediately and can easily take measures against the accident. In addition, the key holder is made up of only two parts, the main part of which is the holder body and the hollow cylindrical body. It is effective in spite of the small number of parts. A key holder with high production efficiency can be provided.
