The lever operation direction conversion device of the push-pull door lock

The present invention relates to a push-pull door lock that opens and closes a door by releasing a locked state while pushing or pulling a push-pull lever. More specifically, the lever operating direction is operated to push or pull a push-pull lever according to the opening and closing direction of the door. It relates to a lever switching direction switching device of the push-pull door lock to switch.

In general, a door lock is a locking means for opening and closing a door by mounting on a door, and a digital door lock by a Motis and a keypad, and a handle type door lock by a ratchet unit and a handle unit have been mainly used.

In particular, in recent years, in addition to digital door locks or handle-type door locks, push-pull door locks that unlock the doors while pushing or pulling the push-pull levers provided on both sides of the door are frequently used.

These push-pull door locks have been disclosed in various forms, mainly consisting of inner and outer push-pull door locks installed on the inside and outside of the door and door locking means installed buried in the doors to push the inner and outer push-pull door locks. The door is opened while the lever is pushed or pulled according to the opening/closing direction of the door to unlock the door locking means.

These conventional push-pull door locks are divided into a form that is configured to be unlocked when both the push-pull lever is pressed or pulled, or configured to be unlocked only when the push-pull lever is pressed or pulled. In the former case, the push-pull lever is inside the door. If you push the push-pull lever from the outside of the door to close the door after pushing the door open, there is a hassle in use to push and close the door from the outside of the door while the door lock cannot be locked due to the push-pull pull-up. In accordance with the opening/closing direction of the door, the installation direction of the door lock should be changed and installed. For example, when the door is opened on the indoor side, it must be unlocked by a pressing operation on the outdoor side and unlocked by a pulling operation on the indoor side. On the other hand, when the door is opened on the outdoor side, it must be unlocked by a pulling operation on the outdoor side and unlocked by a pressing operation on the indoor side. Thus, two types of push-pull door locks are produced. According to the opening and closing direction of the door, two types of push-pull door locks must be installed in accordance with the operating direction, so there is a problem in that installation workability is very uncomfortable in the field.

In order to solve the problems of the prior art, in Patent Registration No. 10-1868469, the interior of the push-pull lever can be switched by flowing the interior switching plate left and right according to the opening/closing direction of the door. And because it is manufactured separately on the outdoor side, it was made to provide excellent installation efficiency in the field as well as efficiency and economy.

That is, a rotating actuator by a fixed shaft with a spring mounted therein is coupled to the inside of the main body, a push-pull lever and a flow rod vertically elevated inside the main body are coupled to the rotating mechanism, and the door locking means is coupled to the flow rod. Rotating the pulley is coupled to the axis of rotation of the shaft to open the door while unlocking the door by the rotation of the rotating tool by the push or pull operation of the push-pull lever and the lifting of the flow rod, the inside of the body By forming a switching plate that selectively suppresses the lifting and descending directions of the working tool, the restraining protrusion of the rotating working tool inserted into the switching insert hole of the switching plate is supported in the upper or lower direction as the switching plate is moved to the left and right. The push-pull lever is selected to operate in the direction of pressing or pulling.

However, in the case of the above-described conventional push-pull door lock, it is inconvenient to switch, since the switching plate is adjusted while moving the left and right as a whole to change the operating direction of the push-pull lever. There was a problem in that it could move and cause malfunction after installation.
