Description of the Related Art Conventionally, as a key accessory, for example, a remote control means configured to remotely control a key cylinder attached to a door by infrared rays, such as a keyless entry of a car, with respect to a key grip portion. Various configurations have been proposed, such as those incorporating a light to illuminate the keyhole at night or the like, and those incorporating a key in a card to improve the storage of the key in a wallet or the like. ing.

[0003]

By the way, when the user goes out of the house in a hurry, the user may feel anxious as if he or she forgets to lock the door after going out.
Usually, such forgetting to lock is often noticed at a relatively short distance from the house, so it is troublesome to return to the house and check again, but when you are in a hurry or when you notice far away In some cases, such as when there is no time to return, it is necessary to go to the destination with anxiety. Conventionally, this kind of complication and anxiety associated with forgetting to lock is well known, but an effective means for solving the problem that can be put into practical use has not yet been proposed.

[0004] It is an object of the present invention to provide a key accessory having a lock confirmation function capable of immediately eliminating the complication and anxiety associated with forgetting to lock.

[0005]

According to the first aspect of the present invention, there is provided a key accessory having a lock confirmation function, comprising: a hollow holder;
A slider provided inside the holder so as to be freely retractable and provided with position switching means for alternately switching the slider between a protruding position and a retracted position each time a push operation is performed, so that the key operation unit extends in the slider protruding direction. The key holding portion is fixed to a holder or a slider, and the slider is pushed by the key cylinder every time the key is inserted into the key cylinder for locking and unlocking.

Therefore, when the key is inserted into the key cylinder for locking, the slider is pressed against the key cylinder, and is switched to the projecting position or the retracted position by the position switching means, and is maintained in the switched position. Will be done. Then, when the key is inserted into the key cylinder for unlocking next time, the slider is switched to the immersion position or the protruding position opposite to the previous position, and is maintained in the switched position. For this reason, for example, the state where the slider is held at the projecting position is set to the locked state,
By setting the state held at the retracted position to the unlocked state, it is possible to confirm whether or not the slider is locked even after going out based on the state of the slider.

Further, in this key accessory, it is conceivable that the position may be switched by pushing the slider while the key is stored in a bag, a pocket, or the like. In the position switching means, a lock switch for regulating the movement of the slider is provided, and this lock switch is operated when storing in a bag or a pocket,
It is preferable that the position of the slider is not accidentally switched.

However, even with this key accessory, if the locking or unlocking operation is performed an even number of times continuously as described below, the locked state and the unlocked state are displayed oppositely, thus causing a malfunction. Remains. When locking and unlocking operations are repeated an even number of times for confirmation, etc.When locking and unlocking operations are performed with different keys using multiple duplicate keys and locking and unlocking operations are repeated an even number of times. In order to prevent this phenomenon, in this key accessory, it is necessary to confirm the positional relationship of the slider when going out, for example.

According to a third aspect of the present invention, there is provided a key accessory having a lock confirmation function, comprising a hollow holder and a rotating body fixed to a key holding portion, the holder being rotatable by a certain angle in a key rotating operation direction. And a display unit for displaying the direction of inclination of the rotating body when rotating at least one of the keys for locking or unlocking.

Therefore, when the key is inserted into the key cylinder for locking and unlocking and is rotated, the rotating body and the key are rotated by a fixed angle relative to the holder, and are rotated in at least one of the locking direction and the unlocking direction. When the rotating body rotates, the inclination direction of the rotating body is displayed, and it is possible to confirm that the key cylinder is in the locked state or the unlocked state.
In addition, since the rotation direction of the key is usually opposite to the locking direction and the unlocking direction, it is possible to prevent malfunction of the key accessory in the above case.

According to a fourth aspect of the present invention, there is provided a key accessory having a lock confirmation function, comprising: a holder attached to a key holding portion; a lock switch operated by an insertion operation or a rotation operation for locking a key to a key cylinder. Display means for displaying the operation state of the lock switch. In this key accessory, it is possible to easily confirm that the key cylinder is in the locked state or the unlocked state by looking at the display contents of the display means. However, in the case where the lock switch is operated by the key insertion operation, claims 1 and 2
As in the case of, a malfunction may occur. Further, in the case where the lock switch is operated by rotating the key, the malfunction in the above case can be prevented.

Here, a confirmation switch for confirming the operation state of the lock switch is provided as described in claim 5,
It is preferable that the lock switch and the confirmation switch be turned on to display the locked state on the display means. That is, the display means does not operate unless the confirmation switch is operated, so that the power consumption of the display means can be reduced as much as possible.

According to a sixth aspect of the present invention, it is conceivable to provide timer means for resetting the display contents of the display means after a certain time has elapsed since the operation of the lock switch.
In this key accessory, malfunctions in the above cases can also be prevented. Further, since the display is reset after a certain period of time, the power consumption can be reduced. However, even with this key accessory, if the locked state cannot be checked after a certain period of time, if you return to get a lost item, etc. However, there is a problem that a locked state is displayed even though the door is unlocked. In order to prevent these problems as much as possible, it is preferable that the time until the display content is reset can be changed according to the user's preference.

According to a seventh aspect of the present invention, it is also conceivable to provide a clock means for displaying on the display means the elapsed time since the lock switch was operated or the time at which the lock switch was operated. In other words, since the elapsed time after going out or the time at the time of going out can be roughly estimated, it is determined that the display is locked if the displayed content is as expected, and if it is far from the expected, the locking is forgotten. You can see that. In this key accessory, malfunctions in the above cases can also be prevented. In addition, this key accessory can prevent the problem in the case of claim 6. Also in the case of, if the user's memory is correct, the locked state can be reliably determined. Note that, in order to easily remind the state at the time of the locking operation, a plurality of past locking times may be stored.

The key accessory having the lock confirmation function according to the present invention is provided with a hollow holder, a slider housed inside the holder so as to be able to come and go, and a fixed time interval between the holder and the slider, when the holder is subjected to tension or compression deformation. And an elastic body that gradually restores to its original shape by applying the key to the holder or the slider so that the key operation part extends in the direction in which the slider protrudes, for locking and unlocking. Each time a key is inserted into the key cylinder, the slider is pushed by the key cylinder, so that the elastic body is subjected to tensile or compressive deformation.

Therefore, in this key accessory, the elastic body functions in the same manner as the timer means in claim 6, and every time the key is inserted into the key cylinder, the elastic body is operated to be pulled or compressed, When the elastic body has not returned to its original shape, it is known that the key was operated relatively recently. Moreover, the locked state can be checked with a simple configuration using an elastic body. However, even when the lock is opened, the elastic body is subjected to a tension or compression operation, but it is not necessary to check the locked state after returning home, so this is a useless operation but does not cause misunderstanding.

In the case where a transparent material is used as the holder as described in claim 9, the internal structure can be visually checked, so that the design is excellent.
