Therefore, the cost required for the lock device is low, and an excellent effect is obtained that the update key can be used without waste.

The best mode for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 and FIG. 2 show a schematic configuration of a main part of a lock device 1 according to the present invention.

  First, the lock device 1 according to the present embodiment includes an outer cylinder 2 in which a fitting hole 3 is formed, and an inner cylinder 4 that is loosely fitted in the fitting hole 3 so as to be rotatable.

  A key insertion groove 6 into which the key 5 shown in FIG. 3 and the like is inserted is provided in the front-rear direction of the inner cylinder 4.

  Further, a first sliding hole 7 communicating with the side surface in the width direction of the key insertion groove 6 is provided in the radial direction of the inner cylinder 4, and further, a first sliding hole 7 communicating with the first sliding hole 7 in a substantially straight line state. Two sliding holes 8 are provided in the radial direction of the outer cylinder 3.

  As can be understood from the drawing, the first sliding hole 7 accommodates a first pin 9 and the second sliding hole 8 is given a biasing force to the inner cylinder 4 side by a spring or the like. The second pin 10 is accommodated.

  Further, a detachable pin 11 having a spherical shape is interposed between the first pin 9 and the second pin 10.

  The shape of the detachable pin 11 is not limited at all, and may be spherical or rectangular. However, the detachable pin 11 formed in a spherical shape has an advantage that the detachment operation described later can be performed smoothly.

  Further, a detachable pin accommodation hole 12 is provided at a predetermined position on the outer peripheral surface of the inner cylinder 4 to remove and accommodate the detachable pin 11 from between the first pin 9 and the second pin 10.

  Here, when the operation hole 13 provided in the key 5 is a relatively deep operation hole 13 as shown in FIG. 1A, the first pin 9 and the detachable pin 11 are provided in the inner cylinder 4. The inner cylinder 4 is fully accommodated in the first sliding hole 8, and the inner cylinder 4 is rotatable so that the cylinder lock can be locked and unlocked.

  However, as shown in FIG. 1B, when the operation hole 13 provided in the key 5 is a shallow hole, the depth direction of the first sliding hole 8 is filled with only the first pin 9. Thus, the second pin 10 and the detachable pin 11 remain in the second sliding hole 8 of the outer cylinder 2.

  Therefore, when the key 5 is rotated from that state, the inner cylinder 4 rotates, and the detachable pin 11 is detached and accommodated in the detachable pin accommodation hole 12.

  Thereafter, when the operation hole 13 provided in the key 5 is relatively deep as shown in FIG. 2B, a biasing force is applied to the inner cylinder 4 side. The second pin 10 is slid and the leading end of the second pin 10 enters the first sliding hole 7, thereby preventing the inner cylinder 4 from rotating.

  Here, as shown in FIG. 7, first, in this embodiment, five keys 5 (one base key and four update keys) can be used.

  Here, the key 5 shown in (1) of FIG. 7 is the key 5 to be used first.

  When this key 5 is used, the four first sliding holes 7 and the second sliding corresponding to the deep operation hole 13 (four operation holes from the base end side to the front end side of the key 5). A first pin 9, a second pin 10 and a detachable pin 11 are accommodated in the holes 8, respectively.

  When the basic key 5 shown in FIG. 7A is used, the inner cylinder 4 can be rotated in all the four positions shown in FIG. 1A, and as a result, the cylinder lock of this embodiment is used. Can be locked and unlocked.

  Next, it is assumed that the use of the key 5 shown in (1) of FIG. 7 is stopped, and the key 5 (first update key) shown in (2) of FIG. 7 is used according to the order of key use.

  In such a case, first, the key 5 (first update key) shown in FIG. 7B is inserted into the key insertion groove 6.

  Then, the shallow operation hole 13 located on the most proximal side of the key 5 shown in (2) of FIG. 7 is in the state of FIG. 1 (B), and can be detached by rotating the inner cylinder 4 from that state. The pin 11 is accommodated in the detachable pin accommodating hole 12 as shown in FIG. 2A, and when the key 5 which is the base key shown in FIG. ), The key 5 which is the basic key shown in (1) of FIG. 7 cannot be used.

  Further, when the use of the key 5 shown in (1) and (2) of FIG. 7 is disabled and the user wants to use the key 5 (second update key) shown in (3) of FIG. 7, (3) of FIG. ) Is inserted into the key insertion groove 6 and rotated.

Then, the shallow operation hole 13 located second from the base end side of the key 5 shown in FIG. 7 (3) is in the state of FIG. 1 (B). The possible pin 11 is accommodated in the detachable pin accommodating hole 12 as shown in FIG. 2A, and when the key 5 shown in FIGS. 7A and 7B is used thereafter, FIG. In this state, the original key and the two keys 5 as the first update key shown in (1) and (2) of FIG. 7 cannot be used.
Further, when it is impossible to use the key 5 shown in (1), (2), and (3) of FIG. 7 and it is desired to use the key 5 (third update key) shown in (4) of FIG. 7 is inserted into the key insertion groove 6 and rotated.

Then, the location of the shallow operation hole 13 located third from the base end side of the key 5 shown in (4) of FIG. 7 becomes the state of FIG. 1 (B), and when the inner cylinder 4 is rotated from this state, The releasable pin 11 is accommodated in the releasable pin accommodation hole 12 as shown in FIG. 2A. After that, when the key 5 shown in FIGS. 7A, 7B and 7C is used, In the state shown in FIG. 2B, the key 5 shown in FIGS. 7A, 7B and 7C cannot be used.
Further, when the use of the key 5 shown in (1), (2), (3), and (4) of FIG. 7 is disabled and the user wants to use the key 5 shown in (5) of FIG. The key 5 (fourth update key) shown in (5) is inserted into the key insertion groove 6 and rotated.

Then, the first pin 8 and the second pin 9 accommodated in the sliding holes 7 and 8 corresponding to the shallow operation hole 13 located second from the front end side of the key 5 shown in FIG. When the releasable pin 10 is in the state shown in FIG. 1B and the inner cylinder 4 is rotated from this state, the releasable pin 11 is accommodated in the releasable pin accommodation hole 12 as shown in FIG. After that, when the key 5 shown in (1), (2), (3) and (4) of FIG. 7 is used, the state shown in (B) of FIG. 2 is obtained and (1), (2), The key 5 shown in (3) and (4) cannot be used.
As described above, in this embodiment, the keys 5 from (1) to (5) shown in FIG. 7 can be updated and used. However, the update use of the key 5 is only (1) in FIG. , (2), (3), (4) and (5) must be used in order.

  Therefore, for example, if the key (5) is used by skipping (1) to (2), (3), (4) in FIG. 7, all the keys 5 (2), (3), (4) are used. It will not be possible.

  This is because, when the key 5 in FIG. 7 (5) is inserted and the inner cylinder 4 is rotated, the operation hole 13 located second on the distal end side from the operation hole 13 located on the first proximal side of the key 5 Since the four operation holes 13 are shallow operation holes 13, the first pin 8 and the second pin accommodated in the first sliding hole 7 and the second sliding hole 8 respectively corresponding to the shallow operation hole 13. 9 and the detachable pin 10 are in the state of FIG. 1B, and when the inner cylinder 4 is rotated from that state, the detachable pins 11... Can be detached as shown in FIG. When the key 5 shown in (1), (2), (3) and (4) of FIG. 7 is used thereafter, the state shown in (B) of FIG. 2 is obtained. This is because the keys 5 shown in (1), (2), (3) and (4) of FIG.

  Therefore, in order to be able to use the five keys 5 in order, it is important that the so-called renewed key 5 is used in an order that is not mistaken and that there is no error.

  Therefore, in this embodiment, a storage and package for a plurality of types of keys 5.

  That is, as shown in FIGS. 5 and 6, first, three keys 5 (fourth update keys) to be used last are formed as the first package portion 14.

  Next, the second most frequently used key 5 (third update key) is packaged together with the first package part 14 to form the second package part 15.

  Further, together with the second package portion 15, three keys 5 (third update key) used third from the last are packaged to form a third package portion 16.

  Further, together with the third package portion 16, three keys to be updated and used first are packaged to form a fourth package portion 17.

  Then, the third package 5 is packaged together with the fourth package part 17 to form the fifth package part 18.

  Here, the key 5 has a set of three, but is not limited to three. In forming each package part, it is preferable to use a material that is durable and cannot be easily broken.

Further, a non-transparent material that does not know that the key 5 is housed inside is preferable.
Therefore, as understood from FIG. 6, initially, the user of the lock device of this embodiment acquires the key 5 together with the cylinder lock device of this embodiment in the state of the fifth package portion 18.

  Then, for example, the first lock device user of the present embodiment such as a construction company opens the fifth package portion 18 and is exposed in the fifth package portion 18 as shown in FIG. The key 5 is used as the base key.

  Next, for example, after the building is completed, the contractor hands over the group of keys 5 packaged as the fourth package part 17 to the original home acquirer.

  Here, as shown in FIG. 6 (2), the initial home acquirer opens the fourth package part 17 and easily selects the first updatable key 5 that is exposed. And take it out.

  When the first renewable key 5 is used to perform the locking / unlocking operation, the aforementioned detachable pin 11 is detached and accommodated in the detachable pin accommodation hole 12.

  As a result, the key 5 used by the contractor is disabled, and only the first updatable key 5 can be used.

  Furthermore, as shown in FIG. 6 (2), the original home acquirer possesses a group of keys 5 that can be updated in the next stage as the third package unit 16, and the home acquirer has changed over a long period of time. However, the cylinder locking device can be updated by simply handing over the third package portion 16.

  That is, for example, even if the house is transferred after several decades and the owner of the house changes, if the third package part 16 is handed over, it is never necessary to replace the cylinder lock device body itself.

  As shown in (3) of FIG. 6, the new home acquirer can open the third package portion 16 and select the exposed key 5 in the open state. Then, the use of the key 5 that has been used conventionally can be updated to the unusable state, and only the key 5 can be updated.

For example, even if the homeowner is changed frequently, it is possible to easily change keys by handing each package part.

Therefore, it is not limited to the number of packages that can be updated four times as shown in this embodiment, and is not limited to the packaging method shown in this embodiment. Furthermore, the package is not limited to the package of the present embodiment as long as the user can use the keys in the determined order.
