BACKGROUND ART [0002] Recently, as a digital door lock device becomes popular, an apparatus for opening a door by turning a knob after inputting a predetermined password is known. However, since it is generally designed around the right handle (excellent), most of the doors are opened by rotating the handle in the clockwise direction with the right hand.

Recently, right-handed (good) and left-handed (left) models have been released to solve this problem.

In recent years, a structure has been disclosed in which a handle of a door lock is opened (pushed) or pulled (pulled) without rotating. However, due to the complexity of the internal design parts, door lock apparatuses having a dual structure capable of rotating the handle or push-pulling have not been developed. In addition, since the handle is not a rotatable type but a separate design, it is uncomfortable for a consumer.

Due to the structural limitation of such a door lock device, a product reflecting the various installation requirements of the consumer has not been developed, and a door lock device capable of opening by any action (push-pull operation or rotation operation) of the consumer has not been developed.

The body protrusion 102a functions to open the handle spring 90 when the handle stopper 100 is rotated counterclockwise (refer to FIG. 7).

The four-direction fixing pin fixing pin 120c is protruded from the inside of the body 120 and is located closer to the handle stopper 100. The two-direction fixing pin fixing pin 120d is fixed to the four-direction fixing pin fixing pin 120c The gripper stopper 100 is located at a position farther away from the gripper stopper 100 than the gripper stopper 100 is.

The handle spring 90 is a spring for restoring the right and left bodies 40, 50 and the handle stopper 100, which are rotated by a force, to an initial position. One end of the handle spring 90 is formed with one of the pair of handle spring hooks 100b and the other end is formed with a handle stopper hook 90a to form a pair of knob spring hooks 90b, Lt; RTI ID = 0.0 > 100b. &Lt; / RTI >

The handle stopper 100 is in the shape of a disk, and a stopper through-hole 100d having a substantially octagonal shape is formed in the central region so that the combined right and left bodies 40 and 50 are fitted. Four hooks 100a are formed around the handle stopper 100 at intervals of 90 degrees. A two-way handle fixing groove 100c is formed in the two facing four directional locking jaws 100a. The depth of the two-way handle fixing groove 100c is configured to be shallower than the depth of the four-direction stopping hook 100a. A pair of gripping spring hooks 100b are extended and bent in one of the remaining two four-direction locking hooks 100a on which the two-way handle fixing groove 100c is not formed. The pair of gripping spring catching jaws 100b are provided so that the gripper stopper catching jaw 90a and the gripping jaw 90b are engaged with each other in the rotating direction.

The holding ring 200 serves to fix the position of the handle stopper 100 and the like without being peeled off.

The handle fixing pin 110 is in the shape of a wand that is bent at one end. The bent end is fixed by being selectively fitted to one of the four-direction fixing pin fixing step 120c and the two-direction fixing pin fixing step 120d. The other end of the handle fixing pin 110 is inserted into the four-way locking protrusion 100a to fix the handle stopper 100 or touch the two-way handle fixing groove 100c to allow the turning of the handle stopper 100.

[ The position of the handle 10 as shown in Fig. 15 is an installation method for a right handle (excellent).

Accordingly, when installing an embodiment of the present invention on a door, the installer determines the position of the handle as one of a left-handed and right-handed type according to a request of a customer, and then the handle 10 is moved only by the push- (5) and the push-pull operation (2) are used together to decide whether to open or not. 8, 10, 13, 14, and 15 according to the determination. If the customer selects the upward handle 10 as shown in Fig. 9 or the downward handle 10 as shown in Fig. 11, the turning operation 5 can not be used and the door must be opened only by the push pull operation 2. [

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, the position of the handle stopper 100 and the handle fixing pin 110 for the push-pull operation 2 may be any one of Figs. 8 to 15. Fig.

First, when the handle 10 is pushed, the (pushing) drive handle 30 is rotated about the drive handle shaft 30b. At this time, while the eccentric drive projection 30c pushes the drive projection stop 60a in the normal direction, the drive shaft 60 itself rotates while pulling the force of the drive spring 70 (refer to arrows in Figs. 4 and 5) Reference). When pulling the handle 10 (pull), the drive shaft 60 is rotated in the opposite direction due to the opposite direction of movement.

The rotation of the drive shaft 60 is transmitted by rotation of the opening / closing means (not shown) to open the door. When the user releases his or her hand, the handle 10 returns to the initial position due to the restoring force of the drive spring 70. [ Through this process, the rotary motion is transferred to the pull or push operation.

Rotational motion of the embodiment

Hereinafter, a specific operation method of the rotation operation (5) will be described with reference to the accompanying drawings. The position of the handle stopper 100 and the handle fixing pin 110 for the rotation operation 5 should be either the position shown in FIG. 13 or the position shown in FIG.

First, the driving handle 30, the body cover 80, the right and left bodies 40 and 50 rotate integrally when the knob 10 is rotated in the clockwise direction. At this time, the gripper stopper 100 fitted to the ends of the right and left bodies 40, 50 is rotated (see Figs. 13 and 14). That is, the handle stopper 100 can be rotated by an angle of the entirety of the four-direction locking tab 100a and the two-direction fixing pin locking tab 100c.

The rotation of the right and left bodies 40, 50 is transmitted by the rotation of the opening and closing means (not shown) to open the door. When the user releases his / her hand, due to the restoring force of the handle spring 90, the handle 10 returns to the initial position. Through this process, the rotary motion 5 of the knob 10 is transmitted to the rotary motion of the opening / closing means.

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.
