Description

[Detailed description of the invention] The present invention relates to a key, and in particular, it is designed to ensure that the key can be locked or unlocked, and even after the key has been removed from the keyhole of the lock, the lock can still be locked using this key. This allows you to easily check the status.

As shown in FIG. 1, a conventional key 1 has a lock insertion part 1a integrally protruding from one side of a knob 1b. When locking, the lock insertion part 1a is inserted into a keyhole 2a of a lock 2. and move the knob 1b in the - direction (arrow A) centered on the axis O.
) to lock the lock, and then when attempting to remove the lock insertion part 1a from the keyhole 2a, there is a drawback that the key 1 is often removed without confirming that it is completely locked. Or the key 1 even though it was locked once.
Sometimes the lock would unlock again when returning it to the extraction position.

This is due to the fact that it is difficult to specify the position and sensation of pulling out the lock insertion portion 1a, and it is not possible to easily confirm whether the lock is in a locked state or an unlocked state.

The present invention was devised in view of the above-mentioned circumstances, and an object of the present invention is to provide a key with a simple structure that allows easy and reliable confirmation of locked and unlocked states.

Hereinafter, embodiments of the present invention will be described based on the drawings.

FIG. 2 is a partially cutaway perspective view of an embodiment of the present invention, in which a cylindrical shaft fitting part 13 is protruded from one end of a knob 12, and a lock insertion part 11 is formed separately from the knob 12. A shaft portion 11b that is inserted into the shaft fitting portion 13 is provided at the base of the shaft.

The shaft fitting portion 13 is provided with an opening 16, and the opening 16 is provided with a pair of recesses 16a and 16b that extend in the circumferential direction of the shaft fitting portion 130.

Further, the shaft portion 11b of the lock insertion portion 11 is provided with a projection 15, and this projection 15 and each recess 16 of the opening portion 16 are provided.
a.

16b, the shaft fitting portion 13 and the shaft portion 1
In addition to setting the relative rotation range with 1b,
A resilient member 14 is interposed which urges the lock insertion portion 11 in the direction of the axis 08.

The resilient force of the resilient member 14 is determined by the drag force that prevents the knob 12 of the lock insertion portion 11 from rotating, and the drag force caused by the compression of the lock 17 in the direction of the keyhole 17a, which is the direction of the axis o8. When the protrusion 15 crosses the recess 16a, the protrusion 15
The recess 16b is moved to the other recess 16b.

Next, the operation of the present invention will be explained.

When the lock insertion section 11 is inserted into the keyhole 17a in the state shown in FIG. It is necessary to rotate the knob 12 until the protrusion 15 moves from one recess 16a to the other recess 16b.

In other words, since the protrusion 15 moves only when the door is completely locked, it is possible to immediately confirm that the door has been locked by the feel or the magnitude of the impact given to the finger on the 70th festival.

Conversely, when unlocking, insert the lock insertion part 1 in the state shown in Figure 4.
1 into the keyhole 17a and turn the knob 12 in the direction of arrow C in FIG. There's nothing to do.

Therefore, it is possible to reliably confirm whether or not the door is unlocked.

Note that when the lock insertion part 11 is pulled out from the lock hole 17a, that is, when the key 10 is carried alone, the protrusion 15 is recess 16a in a state where the key 10 is removed;
It does not naturally move from the locked position with 16b.

That is, the protrusion 15 will not move unless a force to press the knob 12 in the direction of the axis 08 and a force to rotate the shaft fitting part 130 in the circumferential direction are applied at the same time.

As described above, according to the present invention, it is possible to easily confirm that the lock or unlock has been secured, so there is no need to reconfirm the lock or unlock after removing the key from the lock. I can provide you with the key.
