Description

Door lock with double door handle

The present invention relates to a device that can serve as a handle and a door lock by installing a door lock on the handle of the door, more specifically, to maintain a firm installation state between the operation pin pinned to the upper support of the handle, during the vertical movement between the operation The door lock combines the handle of the door that the shaft can be easily fastened to the shaft groove of the fixed bar even though the rotation of the shaft for operating the fixed bar of the door lock smoothly without noise and the position of the fixed bar installed depending on the thickness of the door. It is for providing a device.

Generally, door handles and door locks that are separated are usually installed separately for the doors such as the front door and the like, and separate door locks may be separately installed when it is determined that the locked doors cannot be secured by the door lock alone. However, when the handle and the door lock, the auxiliary door lock is distributed in various places in this way, there is a problem that the finish of the door is considerably off.

Therefore, in view of the above point, the upper support part of the handle bar is formed in a wide and long way, and then many door locks are used as the handles of the doors in which the door lock and the auxiliary door lock are integrally installed on the support part. Since the door lock and the auxiliary door lock installed in the handle and the upper support part are kept as close as possible to each other, when the door is installed, the exterior of the door is quite beautiful and is receiving a lot of acclaim.

As described above, the door lock device having a conventional door handle in which the door lock is installed on the upper support portion of the handle is generally inserted into a hole of the upper support portion, and the rear protrusion between the pinned operations moves the ruler of the door lock to the left or right. It is a structure that hangs on the studs.

In addition, the operation between the operation of the door lock device is generally the upper end of the projection is supported by a spring, when the operation is pressed with a finger, the spring is compressed by the projection that rises around the pin axis while being pressed and pressed by the finger. When it is released, it is configured to move around the pin shaft and return to its original position by the spring force of the compressed spring.

However, when the rear end of the operation is caught by the locking protrusion of the shaft that moves the locking bar of the door lock to the left and right as described above, the rear end of the operation may well detach from the locking protrusion of the shaft. There is a problem in that a lot of noise occurs during operation because the rotation of the shaft is not smooth when pressing the operation.

In addition, the conventional door lock device is fixed to a predetermined length of the shaft protruding from the cover coupled to the back side of the upper support portion of the handle while the shaft to move the locking bar of the door lock to the left and right while rotating the movement when installing the handle to the door If the position of the ruled bar is too close or far from the gate due to the thickness of the door, the shaft may not be well coupled with the ruled bar.

Therefore, in the related art, it was cumbersome to have several shafts of different lengths and then select and install the shafts well according to the thickness of the door. When the handle is produced, even a slight carelessness of the pinned operation moves repeatedly, so there is a tendency to fall out of the pin tongue.

And when the above-mentioned handle is installed and used in the door, when the failure occurs, the center is eccentric by simply removing the handle from the door and opening the cover fastened to the back to fix the defective part or to replace the parts. As the pin shaft between the operation well escapes from the pin tongue, the projection between the operation is well separated from the locking projection of the shaft, there is a problem that the maintenance work due to replacement is very difficult and takes a long time.

Therefore, the present invention was devised to solve the problems of the conventional door lock device that also serves as a door handle as described above, the present invention when the opening and closing the cover fastened to the back side of the upper support portion of the handle is firmly pinched state of operation. It is an object of the present invention to provide a door lock device that combines a door handle that can be maintained while the shaft that moves the locking bar of the door lock during a vertical movement between the operations pinned to the support on the upper side of the handle bar without noise.

Another object of the present invention is that the length of the shaft protruding from the back of the support portion is elastically variable so that even if the position of the ruler bar installed depending on the thickness of the door is somewhat different, the door handle that can be easily fastened to the ruler bar It is to provide a door lock device.
