The lever 40 is axially coupled to the rotation shaft 220 of the rotation support portion 200 and is rotated toward the inclined surface 210 of the rotation support portion 200 about the rotation axis 220,

At this time, the lever 40 is fixed to the rotary shaft 41 for axial coupling with the rotary shaft 220, and the rotary shaft 220 is installed through the rotary shaft 41.

At this time, it is preferable that a coupling protrusion 41a for coupling with a connection shaft, which will be described later, is formed on the bottom surface of the moving shaft 41.

Next, the rotating medium 300 serves to rotate the rotating member 110 in one direction by the push-pull operation of the lever 40.

That is, by the rotation of the rotary member 300 by the push-pull operation of the lever 40, the polygonal pin P coupled to the rotary member 110 is rotated by the first groove 13a or the second groove 13b to release the locked latch bolt 11 or the dead bolt 12.

The rotating medium 300 includes a connecting shaft 310, an engaging member 320, and a moving plate 330.

The connecting shaft 310 is coupled to the moving shaft 41 and receives the rotational force of the lever 40 and is disposed inside the case 100.

The connection shaft 310 is formed with an insertion groove 311 for coupling with the movement shaft 41.

That is, the engaging projection 41a of the moving shaft 41 is inserted into the insertion groove 311 of the connecting shaft 310 to be engaged.

The engaging member 320 interlocks with the moving shaft 41 to move the moving plate 330 in a straight line.

At this time, the engaging member 320 is axially coupled with the moving shaft 41 so that the engaging member 320 is interlocked with the moving shaft 41, and the moving direction of the engaging member 320 is the same as the rotating direction of the lever 40 moving the moving shaft 41 .

Downward protrusions 321 are formed on both sides of the moving shaft 41 which is axially coupled to the bottom surface of the engaging member 320.

The downward protrusion 321 is coupled to the moving plate 330 to interlock the moving plate 330 when the connecting shaft 310 moves.

The moving plate 330 interlocks with the connecting shaft 310 when the connecting shaft 310 is moved by the lever 40 and rotates the rotating member 110.

The moving plate 330 is formed of a plate and has an engaging hole 331 to which the downward protrusion 321 of the engaging member 320 is coupled at one side and an outwardly projecting protrusion (332) are formed.

The outward protrusion 332 pushes the pivot pin 112 of the pivot member 110 to rotate the pivot member 110.

Between the outward projection 332 and the coupling hole 331 is formed a body hole 333 in the form of a slot in which the body 111 of the rotary member 110 is disposed and a rotary pin 112 of the rotary member 110, A pin hole 334 having a long hole shape is formed.

In other words, when the connecting shaft 310 moves the moving plate 330, the outward protrusion 332 of the moving plate 330 pushes the rotating pin 112 to rotate the body 111 to one side, (40), all the structures are restored by the restoring force of the spring (S).

Meanwhile, a guide block 400 is further installed inside the case 100.

The guide block 400 serves to fix the coupling member 140 and to guide the coupling of the rotation medium 300.

That is, even if the fastening member 140 is coupled to the case 100 as described above, since the pivotal support 200 can move on the case 100, It is a matter of course that the pivotal support 200 is fixed when the direction is determined. By fixing the pivotal member 140 to the guide block 400 using screws or pins, the flow of the pivotal support 200 is restricted You can.

The guide block 400 includes a through hole 410 through which the connecting shaft 310 of the rotating medium 300 passes and a pin hole An interference preventing groove 420 corresponding to the turning radius is formed.

A key box hole 61, a multiple pin hole 62, a rotating pin hole 64, and a connecting shaft hole 63 are formed as a panel for closing the case 100.

Hereinafter, the operation of the push-pull door lock assembly constructed as described above will be described.

Figs. 10A and 11A are views of the initial state of the push-pull door lock assembly in a closed state; Fig.

At this time, the polygonal pin (P) of the push-pull door lock assembly installed on the outdoor side is inserted into the first groove (13a) of the mortis (10) which can operate only the latch bolt (11) The polygonal fin P of the assembly is inserted into the second groove 13b of the mortis 10 capable of interlocking the dead bolt 12 and the latch bolt 11 at one time.

To open the door in this state, the user performs a push-pull operation to pull or push the lever 40 as shown in FIG. 10B.

At this time, the outdoor side lever is pulled out and the indoor side lever is pushed out.

At this time, the lever 40 is rotated about the pivot shaft 220 by using the pivot support 200 as a lever, and has a restoring force by the spring S.

For example, when the door is opened by pulling the lever 40 outdoors, the moving shaft 41 of the lever 40 is moved to the right in the drawing, as shown in FIG. 11B, And moves the moving plate 330 to the right while interlocking with the moving plate 41.

At this time, the outward protrusion 332 of the moving plate 330 pushes the turning pin 112 of the rotating member 110 to the right to rotate the body 111.

 The polygonal pin P coupled to the body 111 is also rotated and the first groove 13a is rotated by the rotation of the polygonal pin P so that the locking of the latch bolt 11 is released.

On the other hand, at the indoor side, by simply pushing the lever 40, the polygonal pin P rotates the second groove 13b to interlock the dead bolt 12 and the latch bolt 11 at one time, Even if the door is locked by the bolt 12, it can be opened easily.

12, the push-pull operation of the lever 40 can be performed in the left and right directions of the door, and the push-pull door lock assembly is a type in which the door can be opened only in one direction, And the lever may be rotated by 180 degrees according to the left-hand type door excellent-type door.

To this end, the fastening member 140 is detached from the guide block 400 by releasing the fastening means coupled to the fastening hole 142 of the fastening member 140 through the guide block 400.

Accordingly, the coupling member 140 can freely rotate between the case 100 and the guide block 400, so that the pivotal support unit 200 coupled to the coupling member 140 can also be rotated.

Thereafter, the pivotal support 200 coupled to the lever 40 is rotated by 180 degrees, and then passes through the guide block 400 using the fixing unit to be engaged with the fixing hole 142 of the fastening member 140.

Thereby, the direction switching process of the lever 40 is completed.

That is, in order to change the direction of the lever 40 according to the left-hand or right-hand door, the fixing unit of the coupling member 140 coupled to the guide block 400 is released and the rotation support part 200, The rotation of the lever 40 can be easily performed by simply rotating the lever 40 by 180 degrees.

As described above, the push-pull door lock assembly according to the present invention has a technical feature that the door can be opened only by one operation of the lever when the door is opened from the room to the outside in the push-pull type door lock.

That is, a separate structure for the operation of the dead bolt 12 is omitted, and the process of releasing the locking of the dead bolt 12 can be performed only by pushing or pulling the lever 40.

Accordingly, the push-pull door lock assembly according to the present invention can improve the convenience of door opening and can open the door quickly in emergency situations.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art.
