Next, the door locking device is operated to be interlocked by a one-touch push button that is operated by elastically pushing the circular key backward, so that the door can be unlocked.

In general, in order to unlock a locked lock, when inserting a unique key into the keyhole, insert it according to the specified shape of the key and the keyhole, and rotate the key to unlock it. This method of operation is generally possible only with both hands. As a result, not only the elderly but also adults may experience discomfort in use depending on circumstances.

Prior art for solving this problem is provided with Korean Patent Publication No. 10-2015-0145212 (name of the invention: a lock without a direction fixed to the key insertion) and Registration Patent 10-0533059 (name of the invention: a door lock device). Became.

The lock without a direction fixed to the key insertion of the prior art, as shown in Figs. 1A to 1E, is a key in order not to have a specific direction when the key A is inserted into the key hole D-1. Make the shape of (A) and keyhole (D-1) circular, and move the slider (E) in a straight line up and down in order to stop turning after inserting the key (A) into the keyhole (D-1). When the key is inserted into the keyhole by moving in the direction, the stop pins (H) (I) that were blocking the progress of the slider (E) are aligned and connected to the lock ring (C) that was pushed upward by the spring (G). The slider (E), which is fixed by the block (F) and interlocked with the lock ring (C), rises upward, and the lock ring (C) is released. When unlocking by inserting a unique key into the locked lock, the key and keyhole There is no need to fit it according to the specified shape of the key, and the effect of unlocking the lock is provided by simply pushing the key (A) into the key hole (D-1) without turning after inserting the key.

However, in this prior art, as shown in Fig. 1e, in order to increase the precision of the stopping pins (H) (I) as the cylinder (D) and the slider (E) are configured in a circular cross-section, the cylinder-side stop where the stopping pins abut. There was a difficulty in fabrication in which the rear end of the pin H and the front end of the slider-side stop pin I must be rounded in the same way as the circular cross-sections of the cylinder D and the slider E.
