  However, in the above prior art, the change in the relative position of the slide body with respect to the case is difficult to see because it is difficult to see behind the linear member that moves following the slide body, and the linear member is locked. There is a problem that it is difficult to determine from the outside whether the lock is released. For this reason, in the said prior art, a key holder may be returned to a key management apparatus in the state which the lock | rock of the both ends of the linear member was cancelled | released (in the state which forgot to lock).

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a sealing tool or the like that can suppress forgetting to lock the ring middle part of the key ring.

  In order to solve the above-described problem, a sealing tool according to one aspect of the present invention is a sealing tool that locks a ring intermediate portion that is positioned on an intermediate side of an end portion in a key ring that can be attached and detached from a key. A case in which the key ring can be mounted via a ring intermediate portion; and a slide member that is slidably received with respect to the case. The slide member locks the ring intermediate portion of the key ring. Between the release position where the ring is released and the lock position where the ring middle portion is locked, and is accommodated in the case so as to be displaced independently of the key ring attached to the case. At the position, a part of the slide member protrudes from one end of the case, and at the lock position, a part of the slide member is accommodated inside the case. It is characterized in that.

  According to the above configuration, at the release position where the lock of the ring middle part of the key ring is released, a part of the slide member protrudes from one end of the case. On the other hand, in the lock position where the ring middle part is locked, a part of the slide member is accommodated in the case. For this reason, depending on whether a part of the slide member protrudes from one end of the case or a part of the slide member is housed inside the case, the ring middle part of the key ring is locked or the ring middle part is locked. It is easy to determine from the outside whether or not.

  Moreover, according to the said structure, the slide member is accommodated with respect to the case so that it may displace independently between the said release position and the said lock position with the key ring with which the case was mounted | worn. In other words, the slide member is configured to move independently of the key ring, and the change in the relative position of the slide member with respect to the case is attached to the slide member as in the technique described in Patent Document 1 above. There is no problem that it is difficult to see behind the moving key ring. As described above, forgetting to lock the ring middle part of the key ring can be suppressed.

  In the sealing device according to one aspect of the present invention, an engagement portion that engages with an engagement hole formed in the case is formed on the side opposite to the part of the slide member. In the position, the engaging portion may engage with the engaging hole. According to the said structure, the relative position of the slide member with respect to a case can displace, and it can prevent that a lock | rock is cancelled | released contrary to a user's intention.

  The sealing device according to one aspect of the present invention includes a plurality of magnets arranged at positions facing each other inside the sealing device so that opposing magnets can be displaced by repelling each other. The magnet may move to a position that prevents the engagement portion from disengaging from the engagement hole. According to the said structure, it can prevent that the engagement with respect to the engagement hole of an engaging part is cancelled | released and the relative position with respect to the case of a slide member displaces contrary to a user's intention.

  A key holder according to an aspect of the present invention is a key holder to which the key ring to be attached to the case of the sealing tool is attached, and an insertion portion that is inserted into an insertion port of a key return portion of a key management device, And a holder main body provided with an extension portion extending to the opposite side of the insertion portion into the insertion port, and the key ring is rotatably attached to the extension portion. It is preferable that rotation of the key ring with respect to the extension portion is prevented in a state in which a part of the slide member protruding from one end of the case to which the key ring is attached is in contact with the insertion portion. According to the said structure, in the state which a part of slide member protruded from the end of the case contact | abuts to the insertion part of a holder main body, rotation with respect to the extension part of a key ring is blocked | prevented. Moreover, in the release position where the lock of the ring middle part of the key ring is released, a part of the slide member protrudes from one end of the case. For this reason, the rotation of the key ring with respect to the extension portion is prevented, so that the user can recognize that the lock of the middle portion of the ring of the key ring is released (forget to lock).

  The lock release device according to an aspect of the present invention is a lock release device that releases the lock of the ring middle portion of the key ring attached to the key holder, and includes an insertion port into which the sealing tool is inserted. The lock of the ring middle part of the key ring may be released by inserting the sealing tool into the insertion port. According to the said structure, a lock | rock can be easily cancelled | released without destroying a key ring or a sealing tool only by inserting a sealing tool in the insertion port of a lock release apparatus.

  A key management device according to an aspect of the present invention is a key management device including the lock release device, wherein an insertion port into which the insertion portion of the key holder can be inserted is formed. It is preferable that a part of the sealing tool enters the insertion port in a state where the insertion portion is inserted into the insertion port. According to the above configuration, in a state where the insertion portion is inserted into the insertion port and a part of the sealing tool enters the insertion port, the rotation of the key ring with respect to the extension portion is prevented. Thereby, since it becomes impossible to release the lock of the middle part of the ring, unauthorized unlocking can be suppressed. In the technique described in Patent Document 1, there is a possibility that unauthorized unlocking may be performed because the connecting member main body (sealing tool) is exposed even when the key holder is returned to the key management device. The key management device according to one aspect of the present invention can avoid such a problem.

  Moreover, according to the said structure, a part of slide member protrudes from the end of a case in the releasing position where the lock | rock of the ring middle part of a key ring is cancelled | released. On the other hand, in the lock position where the ring middle part is locked, a part of the slide member is accommodated in the case. For this reason, it is easy to determine from the outside whether the ring intermediate portion of the key ring is locked or released depending on whether a part of the slide member protrudes from the case or is accommodated in the case. As described above, it is possible to realize a key management device that can suppress forgetting to lock the ring middle part of the key ring.

In the example shown in FIG. 1A, the slide member 21 protrudes from one end of the case 22. Yes. In the present embodiment, the slide member 21 is described as being made of a resin material, but the constituent material of the slide member 21 is not limited to the resin material. For example, the constituent material of the slide member 21 may be a metal material.

  The sealing tool 2 can lock the ring middle portion 1a of the key ring 1. Although details will be described later, in order to place the ring intermediate portion 1a in a locked state, the ring intermediate portion 1a is fitted in the ring intermediate portion fitting hole 22a of the case 22 (the key ring 1 is attached to the case 22). In the state), the lock button 21a may be pushed and accommodated in the case 22.

  On the other hand, if the lock button 21a is protruded from one end of the case 22 in a state where the ring intermediate portion 1a is fitted in the ring intermediate portion fitting hole 22a, the ring intermediate portion 1a is unlocked.

  The holder main body 3 is made of a resin material, and the difference between the insertion portion 31 inserted into the insertion port 51 of the holder return portion 50 (see FIG. 1D) of the key management device and the insertion portion 31 An extension portion 32 extending to the opposite side to the side inserted into the insertion port 51. The insertion part 31 and the extension part 32 are integrally molded. The insertion part 31 has a rectangular parallelepiped shape with a vertical cross section of a vertically long rectangular shape, and a plurality of grooves for preventing resin deformation are formed on the front and back side surfaces shown in FIG. . A bent portion mounting hole 3a to which the bent portion 1b of the key ring 1 is attached is formed on the lower surface side of the extending portion 32 shown in FIG. In the present embodiment, the holder main body 3 is described as being made of a resin material, but the constituent material of the holder main body 3 is not limited to the resin material. For example, the constituent material of the holder body 3 may be a metal material.

The procedure for assembling the accessory of the key holder 10 is as follows.
(1) The bent portion 1 b of the key ring 1 is attached to the bent portion mounting hole 3 a of the extending portion 32 of the holder body 3.
(2) With the ring intermediate portion 1a of the key ring 1 fitted in the ring intermediate portion fitting hole 22a of the case 22 of the sealer 2, the lock button 21a is pressed (the slide member 21 is relative to the case 22). And is accommodated inside the case 22.

  With the above procedure, the key holder 10 is in the state shown in FIG. FIG. 1B is a diagram showing a state of the key holder 10 in a state where the ring middle portion 1a of the key ring 1 is locked. In this state, the key ring 1 (or the sealing tool 2) is supported from the front side to the back side with respect to the extending portion 32 so as to be rotatable about 180 ° independently of the holder body 3. In addition, the rotation range of the key ring 1 (or the sealing tool 2) is not limited to the above-described form. For example, the key ring 1 (or the sealing tool 2) can move from the near side to the lower side with respect to the extending portion 32. The holder main body 3 may be supported so as to be rotatable about 90 ° independently of the holder main body 3.

  Next, FIG. 1C is a diagram showing the state of the key holder 10 in a state where the lock of the ring middle portion 1a of the key ring 1 is released. In the state where the lock of the ring intermediate portion 1a is released, the lock button 21a of the slide member 21 protruding from one end of the case 22 of the sealer 2 is inserted into the holder body 3 as shown in FIG. In the state of abutting 31, rotation of the key ring 1 with respect to the extending portion 32 is prevented. In other words, in the state shown in FIG. 1C, even if the sealing tool 2 (or key ring 1) is to be rotated 90 ° from the near side to the lower side, the insertion portion 31 of the holder body 3 and the sealing tool 2 The lock button 21a comes into contact with the rotation and is prevented from rotating. In this way, the rotation of the key ring 1 with respect to the extending portion 32 is prevented, so that the key user can recognize that the ring intermediate portion 1a of the key ring 1 is unlocked (forgotten to lock). it can.

  Next, (d) of FIG. 1 is a figure which shows a state when the key holder 10 is returned to the holder return part (key return part) 50 of a key management apparatus (refer FIG. 4). In the state shown in the figure, the insertion portion 31 of the holder main body 3 is inserted into the insertion port 51 of the holder return portion 50 (in this state, the insertion portion 31 is the insertion port. I can't see it hidden by 51). In this state, since a part of the sealing tool 2 has entered the insertion port 51, the key ring 1 (or sealing tool 2) cannot be rotated (or rotated) with respect to the extending portion 32. Thereby, since the lock of the ring intermediate part 1a cannot be released, unauthorized unlocking can be suppressed. In the technique described in Patent Document 1, there is a possibility that unauthorized unlocking may be performed because the connecting member main body (sealing tool) is exposed even when the key holder is returned to the key management device. According to the key management device of the embodiment, such a problem can be avoided.
