The rotation of the door handle prevents the rotation of the door handle from being rotated at the full 90 ° rotation, thereby preventing damage or damage to the components included therein. The present invention relates to an improved safety device for lever locks which prevents them from getting caught in the door.

In general, a door lock is installed at a door of a door to lock or release the door. The door lock has a locking function because the interlocking operation device connected to it can not be moved by braking the rotation of the out spindle when the lock button is pressed in the room. It is configured to be maintained.

However, in the case of lever type door lock with a "b" type handle, the force applied to the handle is a small force like a lever, so that the outer door handle can be rotated with a stronger force than the round handle. There is a problem that the accessories that are bound to the handle shaft by the rotational force is deformed or damaged under the influence of the forcible turning power, causing the lock to lose its function.

In this regard, the present applicant has proposed a safety device of a lever lock, which is a registered patent No. 10-0352469, which is designed to achieve idle rotation of an out lever in a locked state in a cylindrical lever lock as shown in FIGS. 1 and 2. A connecting rod (2) guide groove (3) is formed in the coupling cylinder (1) connected to the side incision groove and a semi-circular groove (5) is formed in the rotary tube (4) connected to the out lever by connecting rod guide groove (3) and The semi-circular groove (5) is matched and the connecting rod (2) and the rotary tube (4) with a connecting rod (2) that is built in the connecting rod (2) therein and the elastic spring (6) to the outside tightening elastically When the binding force is applied and the excessive rotational force is applied, the connecting rod 2 rises outward and the out lever is idled, and the hatch opening 11 binds or separates idle with the connector 13 horizontally inserted into the connector rotary cylinder 12. Structure 13, the connector 13 assembled in the connector rotor 12 The spring 15 is pushed by the inclined groove 14 formed in the tubular body 4, and when it rotates the connector rotor 12 with a working rod, it protrudes into the disengagement groove 16 assembled together while moving horizontally. (17) is inserted and bound, and when the reverse rotation to remove the key, the connector 13 is returned to the inclined groove 14 of the rotary tube 4, so that the binding of the tennis ball 11 and the connector 13 is separated. Haejeonggu (11) is made of a structure capable of idling and thawing action as needed.

Therefore, when the out lever is rotated as shown in FIG. 3, the connecting rod 2 is lifted outward from the connecting rod guide groove 3 so that the cylindrical lever lock equipped with the handle is locked to the out lever. The handle rotates 360 degrees when applying excessive force, which prevents excessive rotational force from being deformed or damaged by the locking device and related parts, thus obtaining a safer and more durable cylindrical lever lock and changing the structure of the door lock itself. By adding a few components without the need for a new safety device, new manufacturing devices can be realized, which enables manufacturing and production at a low cost, which can provide many advantages.
