In addition, one side of the handle handle 102 of the outer handle 10 is rotated by forming a slit portion 104 cut along a predetermined length along the handle handle 102 so that the rotary lever 86 to be described later is inserted When the lever 86 is rotated it can be operated in the slit 104 to accommodate the radius of rotation of the rotary lever 86.

On the other hand, one end of the rotation lever 86 of a predetermined length that is hinged to the rotating shaft 43 provided in the case 4 is fitted to the handle bar 84 of the inner handle (8).

The second pushing lever 50 is hinged to the other end of the rotary lever 86 by a second guide shaft bar 14, and the second guide shaft bar 14 is connected to the second pushing lever 50. A predetermined long hole 502 is formed so that) may linearly move.

At the end of the second pushing lever 50, the same curved portion 16 and the roller 18 as the first pushing lever 30 described above are formed, and the roller 18 is a second formed on the fixed block 6 By being coupled to the guide rail 62 serves to guide the second pushing lever 50 to slide.

In addition, the lower end portion of the second guide shaft bar 14 is inserted into the second rail groove 46 formed in the case 4 to guide the second pushing lever 50 to have the arc-shaped movement. Will be

In addition, a first guide shaft 70 is installed by simultaneously vertically penetrating one side of the first and second pushing levers 30 and 50, that is, the position adjacent to the curved portion 16, and the first guide shaft bar ( The lower and upper ends of the 70 may be coupled to the first rail groove 47 and the rail groove 22 formed in the case 4 and the cover 2 to guide the linear movement of the first pushing lever 30. Will be.

Referring to the combination and operation of the present invention configured as described above are as follows.

The handle bars 84 and 102 of the inner and outer handles 8 and 10 described above are inserted into the case 4, but the handle bars 84 of the inner handle 8 are inserted into the handle bars 102 of the outer handle 10. Inserted and combined.

Thereafter, one end of the rotary lever 86 is inserted into the handle stand 84 of the inner handle 8, and the rotary lever 86 is coupled to the rotary shaft 43 provided in the case 4, and then The second guide shaft is hinged to the second guide shaft 14 coupled in the long hole 502 of the lever (502).

At this time, the lower end of the second guide shaft bar 14 is to be inserted into the second rail groove 46.

Meanwhile, the fixing block 6 is coupled to the hinge shaft 45 provided in the case 4, and the fixing block 6 is always drawn into the case 4 by elastic force by interposing a torsion spring 19. Install so that rotational force is applied in the direction.

Thereafter, the roller 18 of the second pushing lever 50 is coupled to the second guide rail 62 of the fixed block 6.

Thereafter, the roller 18 of the first pushing lever 30 fixed to the handle rest 102 of the outer handle 10 is coupled to the first guide rail 61 of the fixing block 6, The first guide shaft bar 70 is coupled to vertically penetrate the second pushing levers 30 and 50, and a lower end thereof is inserted into the first rail groove 47, and then the cover 2 is disposed on the upper part of the case 4. Cover and combine.

At this time, the upper end of the first guide shaft bar 70 is coupled to the rail groove 22 formed in the cover (2).

After inserting and installing the main body (P) coupled through the above-described process into the door, the coupling of the present invention is completed by coupling the inner and outer handles (8, 10) to the handle bars (84, 102).

Referring to the operation of the present invention described above with reference to Figures 3a to 4b as follows.

3A and 3B are views showing an example of operation of the outer handle 10 in the button-type door lock device according to the present invention.

As shown in FIG. 3A, when the user presses the outer handle 10 in a state in which the fixed block 6 is retracted, that is, in the open state of the door, as shown in FIG. 3B, the handle bar of the outer handle 10 is shown in FIG. 3B. As the 102 is retracted, the first guide shaft 70 moves in the first rail groove 47, and the first pushing lever 30 moves forward, and the roller 18 provided at the end thereof is made of the first guide shaft 70. Since the fixed block 6 is pushed by sliding in the single guide rail 61, the fixed block 6 is rotated and drawn out to the outside through the operation hole 48 to lock the door.

Conversely, as the handlebar 102 is pulled out when the outer handle 10 is pulled out, the first pushing lever 30 is reversed so as to be rotated in the reverse direction to the fixed block 6 and drawn into the case 4, as shown in FIG. 3A. As shown, the door is opened.

On the other hand, Figures 4a and 4b is a view showing an example of the operation of the inner handle 8 in the button-type door lock device according to the present invention.

4A shows the fixed block 6 being drawn into the case 4, so that the door is opened.

Subsequently, when the inner handle 8 is pushed, the handle bar 84 is moved forward, and the rotation lever 86 rotates in association with the second guide shaft 14 at the other end of the second rail groove 46. By moving forward in the arc shape and pushing the second pushing lever 50 forward, the roller 18 at the end rotates the second guide rail 62 of the fixed block 6 while rotating the fixed block 6. As shown in Fig. 4B, the door is pulled out through the operation hole 48 to lock the door.

On the contrary, when the inner handle 8 is pulled out, the above-described process is performed in the reverse order, so that the fixing block 6 is drawn into the case 4 and the door is opened as shown in FIG. 4A.

On the other hand, the inner and outer handles (8, 10) are each one of the inner and outer handles (8, 10) because the first and second pushing levers (30, 50) are coupled to the fixed block (6) Is activated, the remaining handles are activated simultaneously.

That is, when the outer handle 10 is pressed to lock the door, as the fixing block 6 rotates, the second pushing lever 50 of the inner handle 8 also interlocks, and thus the inner handle 8 is pressed.

On the contrary, when the door is opened by pulling the outer handle 10, the inner handle 8 is also pulled out in association with the door.

Therefore, if one of the inner and outer handles 8 and 10 is manipulated, the movement of the handle can be seen from the opposite side, thereby providing the convenience of knowing the open / closed state of the door.

As described above, according to the button-type door lock device of the present invention, the door can be opened and closed by a method of pushing or pulling the door handle, it can be easily opened and closed even when the user is holding the object in both hands, In addition, there is an effect that can easily open and close the weak elderly and children.
