In recent years, apartment houses such as office buildings and apartments have been expanding their oaranda in order to secure a wider indoor space. As a result, the use of system windows having excellent insulation and noise barrier has been increasing rapidly.

Inside the window installed between the system window or living room and the veranda used in these houses, a large-sized sliding door with a front glass window is installed for an excellent opening feeling.

In the case of such a sliding door, the door carriage coupled to the door frame is configured to be slidable along a rail formed on the door frame frame. In case of a small door, there is no great difficulty in opening and closing. Because the combined window is heavy, it takes a lot of effort to open and close the sliding door.

In particular, in case of medium / large sliding doors, when the door frame is closed for the first time when the door frame is closed, the weight of the door frame and the friction between the door frame and the mohair combined with the door frame are applied. It is difficult to unlock the sliding door by pulling the handle in unlocked state by applying a force to the hand while unlocking the locking device to open the door. In particular, when the door is opened to a skyscraper, It is more difficult to open.

As a means for solving the above problems, the inventor of the present invention has found that, in a state in which it is inserted into a rail inner groove of a door frame, the stationary body is supported by a coil spring and an operation rod, (U) 20-2008-A, which allows easy opening of the middle / large sliding door by pushing the door frame in the door frame frame while the operating base is rotated by the elastic force of the coil spring when unlocking the door. 0004018 (Sep. 19, 2008) for automatic opening device for sliding doors.

However, in the case of the above-mentioned prior art design, since the operating rod pivoted by the elastic force of the coil spring is exposed to the outside of the door frame after the operation, there is a possibility that the body comes into contact with the exposed portion and is injured. In addition, it is difficult to expect a great effect due to a short stroke distance, and it is also possible to increase the stroke distance by lengthening the opening / closing arm. However, the opening and closing arm is excessively exposed to the outside of the door frame.

In order to solve the problems of the prior art as described above, the inventor of the present invention has provided an opening device for a sliding door interlocking device of the Korean Registered Utility Model Publication (Y1) 20-0455185 (Aug. 23, 2011).

This structure is characterized in that a rack for an opening device is formed in a slide bar formed with a rack to be gear-engaged with a pinion coupled to a knob provided to drive a locking device, and an opening device for releasing the door frame from the door frame frame forward of the rack for the opening device Wherein the opening device comprises a body fixed to the door frame in a state of being inserted into a rail groove, a door opening / closing device assembled to the body by an arm pin so as to be rotatable, And a roller which is assembled to the tip of the arm and a roller which is fixed to the body so that the arm is elastically supported so as to be located inside the body, And when the handle is rotated to open the sliding door, the opening device is interlocked by the rotational force. It is possible to make the length of the arm lengthened by the operation configuration, and when the arm rotates, the door frame is completely released from the door frame frame, so that the opening of the sliding door can be easily performed. It is possible to eliminate safety concerns and worries.

However, in the case of the above-described configuration, since the opening device must be formed separately from the locking device, the manufacturing cost is increased and the installation property is also deteriorated.
