Configuration of Embodiment

1 is a plan view of a door lock device opened in a push-pull operation in accordance with an embodiment of the present invention. As shown in FIG. 1, a number key, a power supply, an electronic circuit, and the like are included in the inside of the body 50, which is a matter of convenience to those skilled in the art.

The handle 10 is a portion directly grasped by the user, and in FIG. 1, the right-handed (excellent) reference state is shown. The handle 10 is assembled through a screw connection. The push-pull motion (or push-pull direction, 2) is defined as the action of pushing or pulling the knob 10 as shown by the dotted line in Fig.

The deco 20 covers the driving body 30 to constitute a part of the outer appearance design and the pair of the decoupling hooks 20a projecting to the rear serve to prevent the driving pin 40 from falling out.

FIG. 2 is an exploded perspective view of the door lock apparatus shown in FIG. 1, and FIG. 3 is an exploded perspective view of the door lock apparatus shown in FIG. 1. FIG. As shown in Figs. 2 and 3, a drive projection 10c is formed on one side of the handle 10. A drive spring hole 10b is formed at the left and right sides of the drive projection 10c, and a drive pin hole 10a is formed through the drive spring hole 10b in the vertical direction. The drive projection 10c has a circular cross-section with a substantially rounded corner.

The driving body 30 is formed with a hole through which the driving projection 10c can be inserted and rotated in the direction of the center axis. The fixing pin groove 30a is formed on the upper surface and the lower surface of the driving body 30, respectively. The fixing pin groove 30a fixes the driving body 30 for installing a handle for a good or a handle for a left hand. The fixing pin groove 30a is for flattening a part of the outer surface of the driving body 30 to restrict the movement in the rotating direction.

The seating groove 30b is recessed in the circumferential direction of the driving body 30, and the driving spring 100 is fitted into the seating groove 30b. To this end, the seating groove 30b is shaped into at least a part of the shape of the driving spring 100.

The driving pin 40 is a pin that serves as a turning center of the push-pull operation. The driving pin 40 is installed so as to pass through the first and second driving pinholes 10a and 30c and can be removed and inserted again when changing the fine knob to the left or changing the left knob to excellent.

The through hole 52 is formed in the body 50 and the driving body 30, the driving pin 40, and the driving projection 10c are located therein.

The handle fixing pin 60 is a metal piece bent twice in a "?" Shape. The upper bent region of the handle fixing pin 60 is fitted and fixed to the lower fixing pin groove 30a of the driving body 30. [ The handle fixing pin 60 is fixed to the body 50 by the fixing pin screw 64 and is subjected to an elastic supporting force by the fixing pin spring 62 so that a more firm fixing force is applied.

The moving plate 70 is a plate-like member that converts the rotational motion of the driving projection 10c into a linear motion 5. [ The first drive groove 70a is formed through the center area of the moving plate 70, and the drive projection 10c is fitted. The guide protrusion 70c protrudes upward and downward along a linear motion on one surface of the moving plate 70. [ The first drive projection 70b protrudes in the cylinder cross-sectional shape in the corner area of the upper surface of the moving plate 70.

The driving spring 100 acts as a circularly bent spring to apply an elastic force for returning the handle 10, which has been operated as a push or pull, to an initial position. To this end, one end of the driving spring 100 is inserted and fixed in the seating groove 30b of the driving body 30 while being bent. The other end of the driving spring 100 forms a spring projection 100a and is fitted in the driving spring hole 10b.

The guide plate 110 is provided adjacent to the moving plate 70 to guide the movement of the moving plate 70 and to hold the rotational position of the first gear 80. The first guide hole 110a is formed through the guide plate 110 in a circular shape, and rotatably supports the second gear 90. The second guide hole 110b has a pair of long holes and a pair of guide protrusions 70c are inserted into the second guide hole 110b to guide a stable linear reciprocating motion.

Fig. 4 is an operational state view for explaining the operation of the moving plate 70 and the first and second gears 80 and 90, and Fig. 5 is a plan sectional view of the door lock apparatus according to the present invention. 4 and 5, in the first gear 80, a second drive groove 80a having a shape corresponding to the first drive projection 70b is depressed in an area in contact with the first drive projection 70b, Respectively. It is more economical that a tooth is formed around only the area in contact with the second gear 90, rather than the entire periphery of the first gear 80. The first gear 80 is engaged with the first gear projection 50a and rotates.

The second gear 90 is engaged with the first gear 80 so as to be rotatable in the rotational direction 9 and is fitted in the second gear projection 50b and rotates. The center shaft of the second gear 90 is formed with a square recess for transmitting an opening rotational force to an opening device (opening means, not shown) of the door. It is more economical that a tooth is formed around only the area in contact with the first gear 80 rather than the entire area around the second gear 90. [

Push-pull operation of the embodiment

Hereinafter, a specific operation method of the push-pull operation 2 will be described with reference to the accompanying drawings. First, when the handle 10 is pushed, a pivoting motion such as a leverage movement occurs around the pushing (driving) pin 40. At this time, the drive projection 10c pushes the moving plate 70 sideways by the rotation angle to cause the linear motion 5 to occur.

5, the linear motion 5 of the moving plate 70 serves to rotate the first gear 80 by the first driving projection 70b. The rotation 7 of the first gear 80 is transmitted to the rotation 9 of the second gear 90 and the rotation 9 of the second gear 90 transmits the rotational force to the opening means of the unshown door Thereby opening the door.

Thereafter, when the user releases his / her hand from the handle 10, the drive spring 100 applies an elastic restoring force to the drive projection 10c. Due to this elastic restoring force, the handle 10 returns to the initial position.

Although the push operation has been described above, the pull operation differs from the push operation only because the same operation is performed with respect to the pull operation but the direction is different.

Although the present invention has been described in connection with the preferred embodiments set forth above, it will be readily appreciated by those skilled in the art that various other modifications and variations can be made without departing from the spirit and scope of the invention, It is obvious that all modifications are within the scope of the appended claims.
