の欠点があつた。(Problems to be solved by conventional technology/devices) Conventionally, when storing car engine keys at a construction site, for example, a method has been adopted in which they are stored all at once in a predetermined location. This method has various drawbacks, such as not knowing who is using the car, forgetting to return the key to the storage location after use, and not being able to check for unauthorized use.
そこで、本出願人は上記欠点を解消するため
に、昭和52年実用新案出願公告第56316号公報記
載のキーの保管装置を出願した。 Therefore, in order to eliminate the above-mentioned drawbacks, the present applicant filed an application for a key storage device described in Utility Model Application Publication No. 56316 of 1978.

るように取付けてなるものである。 When using this key (for example, a car engine key), it cannot be removed without one of the designated keys, and when the desired key is removed, the owner's name etc. is clearly written on it. The lock is designed to ensure that a predetermined key remains, and its structure consists of two cylinder locks arranged in parallel, the inner cylinder of which is fitted into the outer cylinder and is rotatable when the key is inserted. When the cam plate, which has a notch at the rear end of each inner cylinder, is rotated to a point where the trajectories of the large diameter parts intersect and one of the inner cylinders is not at the key insertion/removal position, the notch is attached so as to face the other cam plate.

てなるものである。(Means for Solving the Problems) This invention, like the above-mentioned key storage device, has a common purpose of solving the various drawbacks of the conventional device, but is different in its structure. That is, a plurality of cylinder locks are arranged in parallel so that the inner cylinder fitted into the outer cylinder can be freely rotated by inserting a key, a recess is formed on the outer periphery of each inner cylinder, and a recess is formed on the outer periphery of each inner cylinder. A guide hole that communicates with the recess is formed in the guide hole, and a lock member is movably provided in the guide hole, so that when one inner cylinder is rotated to a position other than the key insertion/removal position, the lock member is inserted into the recess. When the lock member is engaged and the other inner cylinder is in the key insertion/removal position and the locking member is removed from the recess, the one inner cylinder is configured to be unable to rotate. .

料金計２０を採用しないものにも適用できる。 In this embodiment, cam plates 14 and 15 are fixed to the rear ends of both inner cylinders 3a and 3b with screws 16, and a switch mechanism 17 consisting of a micro switch or the like is installed at the upper rear end of the outer cylinder 1. The rollers 18 and 19 fixedly attached to the lower end of the lever of the switch mechanism 17 are brought into sliding contact with the outer circumferential surfaces of the cam plates 14 and 15, and the switch mechanism 17 is connected to the charge meter 20.
It is connected to a lamp, etc. Therefore, the inner cylinder 3
The switch mechanism 17 is turned on or off in accordance with the rotation of the cam plates 14 and 15 which rotate integrally with the keys K1 and K2, and the charge meter 20 can display the charge for use while the key K1 or K2 is being removed. for example,
As shown in FIG. 6, when the key K 2 is removed from the inner cylinder 3b, the roller 19 of the switch mechanism 17 is on the large diameter part of the cam plate 15, and the switch mechanism 1
7 is turned on. However, the structure is not limited to this, and various design changes can be made, and the structure can also be adopted even when the key K1 is removed. Also,
The switch mechanism 17 is not limited to the one in the embodiment, and can be installed at any desired location. For example, a recess is formed on the outer periphery of the inner cylinder 3a, 3b, and at least the rollers 18, 19 of the switch mechanism 17 mentioned above are provided in the outer cylinder 1 so that the rollers 18, 19 of the switch mechanism 17 slide on the locus of the recess. cam plate 14,
It is also possible to implement a system without 15, and in short, a switch mechanism that is turned on or off directly according to the rotation of the inner cylinders 3a, 3b can be provided in the inner cylinder or the outer cylinder. Furthermore, this invention also includes cam plates 14 and 15 provided for calculating usage fees, etc.
It can also be applied to a device that does not employ the switch mechanism 17, the rollers 18, 19, and the fare meter 20.

（実施例の作用） この考案の実施例の作用を以下に説明する。(Effect of Example) The operation of the embodiment of this invention will be explained below.
第１図乃至第３図に示した状態は、内筒３ｂが
キーK2の挿脱位置でない個所まで回動している
（実施例では挿脱位置より時計方向へ45゜回動して

１１にロツク部材１３が係入し、内筒３ａがキー
K1の挿脱位置にあつてその凹部１０よりロツク
部材１３が離脱している。 In the state shown in FIGS. 1 to 3, the inner cylinder 3b has rotated to a position that is not the insertion/removal position of the key K2 (in the embodiment, it has rotated 45 degrees clockwise from the insertion/removal position). However, when the rotation angle is arbitrary), the locking member 13 engages in the recess 11, and the inner cylinder 3a engages with the key.
At the insertion/removal position of K1 , the lock member 13 is removed from the recess 10.
従つて、この場合、内筒３ａつまりキーK1は
挿脱位置にあるからキーK1を抜き取れるが、内

によつて料金計２０を作動できる（第６図参照）。 In order to rotate the inner cylinder 3b, that is, the key K2 , and remove the key K2 from the above state, insert the key K1 into the key hole 4 of the inner cylinder 3a, and insert the key K1 in a place that is not the insertion/removal position. (45° clockwise in the embodiment), the recess 1 of the inner cylinder 3a will open as shown in Figure 5.
0 is the concave portion 1 indicated by the chain line through the guide hole 12 of the outer cylinder 1.
1, and the lock member 13 is in communication with the recess 10.
or 11. Therefore,
When the inner cylinder 3b, that is, the key K2 , is rotated counterclockwise, the locking member 13 is engaged in the recess 10 of the inner cylinder 3a, and is separated from the recess 11 of the inner cylinder 3b, so that the lock member 13 is engaged with the recess 10 of the inner cylinder 3b, and the lock member 13 is disengaged from the recess 11 of the inner cylinder 3b. 1 cannot be rotated and key K 1
It becomes impossible to remove the key K2, and when the key K2 is rotated to the insertion/removal position as shown in the figure,
The key K 2 can be rotated freely and removed. At this time, the fare meter 20 can be operated by the cam plate 15 and the switch mechanism 17 attached to the rear end of the inner cylinder 3b of the removed key K2 (see FIG. 6).
以後、キーK1またはキーK2の抜き取り毎に上
記操作をくりかえすものである。 Thereafter, the above operation is repeated every time key K1 or key K2 is removed.
なお、実施例ではシリンダー錠は１つの外筒に
一体的に形成したが、独立した外筒に別々に設け

錠を使用することなく、キーの挿入により内筒が
外筒に対して回動自在となるものならばどのよう
な形式のものでもよい。 In the embodiment, the cylinder locks are integrally formed in one outer cylinder, but they may be provided separately in independent outer cylinders, or they may be provided vertically in parallel. Also, three or more cylinder locks can be provided, and instead of using a pin tumbler lock as in the example, any type of cylinder lock can be used as long as the inner cylinder can be rotated with respect to the outer cylinder by inserting a key. It may be of a format.
さらに、ロツク部材は実施例の如く２個のボー
ルに限らず、１個または３個以上でもよく、ある
いは１個のピン、その他のものでもよく、その形
状や個数等は任意である。 Further, the locking member is not limited to two balls as in the embodiment, but may be one or three or more, one pin, or other elements, and the shape, number, etc. thereof may be arbitrary.
内筒および外筒に形成した凹部は実施例を示し
た形状に限らず任意であるとともに、その凹部は
各筒に２つ以上適所に形成することもできる。 The recesses formed in the inner and outer cylinders are not limited to the shapes shown in the embodiments, but may be of any shape, and two or more recesses may be formed in each cylinder at appropriate locations.

うに構成してあるから、以下の効果を有する。(Effect of the invention) According to this invention having the above configuration, a recess is formed on the outer periphery of each of the inner cylinders of a plurality of cylinder locks provided in parallel, and a guide hole is formed in the outer cylinder that communicates with the recess. A lock member is movably provided in this guide hole, and when one inner cylinder is rotated to a position that is not the key insertion/removal position, the lock member engages in the recess, and the other inner cylinder is Since the one inner cylinder is configured so that it cannot rotate when the lock member is removed from the recess in the key insertion/removal position, the following effects are achieved.
すなわち、
(1) 一方の内筒が回動可能なとき他方の内筒が可
動不能となるようにしたものゆえ、どちらか一
方のキーは必らずシリンダー錠に保持固定され
た状態となつて保管され、盗難に対して安全で
ある。 In other words, (1) Since one inner cylinder is rotatable, the other inner cylinder is not movable, so one of the keys is always held and fixed in the cylinder lock. stored and safe from theft.
(2) 個人が所有するキーに氏名を明記しておけ
