That is, after the door handle 10 is rotated counterclockwise and the door is fixed, the door handle 10 is rotated clockwise to close the door by returning the fixed door again to close the door or to fix the door at another desired angle. can be For reference, it is preferable that the rotation range in which the door handle 10 is rotated clockwise when the door is returned is greater than the rotation range in which the door handle 10 is rotated in the clockwise direction when the door is first opened.

Again, referring to FIG. 2 , the gear unit 300 has a second rotation shaft 30 that is movable in the vertical direction and may rotate while being engaged with the end of the link unit.

Specifically, the gear unit 300 may rotate in engagement with the end of the second link unit 200b. To this end, the gear unit 300 may be configured to include a gear body 310 to which the second rotation shaft 30 is coupled to the center and a plurality of teeth 320 provided along the circumferential direction of the gear body 310 . have.

The gear body 310 has a through hole in the center so that the second rotation shaft 30 can be coupled thereto, and can be rotated in the same direction as the rotation direction of the second rotation shaft 30 . The second rotation shaft 30 rotates in a state coupled to the through hole and can move in the vertical direction. At this time, the lower outer circumferential surface of the second rotary shaft 30 coupled to the gear body 310 and the inner circumferential surface of the through hole to which the second rotary shaft 30 is coupled may alternately have a screw thread-thread bone shape so that they can mesh with each other during rotation. .

Meanwhile, a support plate 600 of a predetermined size having a through hole through which the second rotation shaft 30 communicates may be coupled to a lower portion of the gear unit 300 . A fixing member (not shown) for fixing the support plate 600 to the lower portion of the gear unit 300 may be provided at a lower portion of the support plate 600 in which the through hole is located. At this time, the fixing member may be provided with an elastic member, the elastic member may be located in the portion provided with the through hole of the support plate 600 may come into contact with the lower end of the second rotation shaft 30 . The elastic member may contract and expand to enable vertical movement of the second rotation shaft 30 by using elastic force. A rack may be regularly formed at the end of the second link part 200b, and a plurality of teeth ( 320) may rotate in engagement with the rack. That is, when the second link part 200b linearly moves to the left according to the rotational direction of the door handle 10, the rack and the plurality of teeth 320 may be rotated by engaging in a counterclockwise direction, and the second link part ( If 200b) is linearly moved to the right, the rack and the plurality of teeth 320 may rotate while engaging in a clockwise direction. For reference, the second rotation shaft 30 may rotate in the same direction as the rotation direction of the teeth 320 .

The hinge part 500 is implemented in a vertical cylindrical shape, and may be provided between the door and the door frame through the hinge 40 .

The hinge part 500 may be connected to the second rotation shaft 30 through the connection member 400 .

The connecting member 400 may be a link member having a predetermined length, and one end may be connected to the second rotation shaft 30 and the other end may be coupled to the hinge unit 500 . At this time, the connection member 400 may move in the same vertical direction as the second rotation shaft 30 rotates and moves in the vertical direction. In other words, the connecting member 400 may move in the vertical direction in a state in which one end is connected to the second rotation shaft 30 and the other end is coupled to the hinge unit 500 .

Meanwhile, as the connecting member 400 moves in the vertical direction, an engagement operation between the connecting member 400 and the hinge unit 500 may be performed inside the hinge unit 500 .

Hereinafter, an engagement operation between the connecting member 400 and the hinge unit 500 will be described with reference to FIGS. 4 , 5A and 5B .

Figure 4 is a view for explaining the meshing operation between the rack and the gear unit in an embodiment of the present invention, Figure 5a is an embodiment of the present invention, when the door handle is rotated counterclockwise It is a view for explaining the meshing operation between the connecting member and the hinge, Figure 5b is in one embodiment of the present invention, when the door handle is rotated clockwise To explain the meshing operation between the connecting member and the hinge It is the drawing shown.

4 and 5A and 5B , the other end of the connecting member 400 may be provided with a plurality of first fitting members 410 protruding upward, and the inside of the hinge unit 500 has a predetermined length. A plurality of second fitting members 520 protruding downward from the fixed body 510 and the fixed body 510 may be provided.

In one embodiment, as the first fitting member 410 and the second fitting member 520 are implemented in the form of protruding pins spaced apart from each other at a predetermined interval, the protruding pins facing the empty space where the protruding pins are not formed. It may have a structure in which it is fitted.

In another embodiment, as one of the first fitting member 410 and the second fitting member 520 is implemented in the form of a hollow groove inside and the other is implemented in the form of a protruding pin, it is implemented in the form of a protruding pin It may have a structure in which the fitting member is fitted with a fitting member implemented in the form of a groove.

Due to this structure, when the door handle 10 is rotated counterclockwise when the door is fixed after opening, the rack and the plurality of teeth 320 move clockwise by the right linear movement of the second link part 200b. According to the engagement, the second rotation shaft 30 may move upward while rotating in a clockwise direction.

Thereafter, as shown in FIG. 5A , as the second rotation shaft 30 moves upward, the connecting member 400 moves upward while the first fitting member 410 and the second fitting member 520 mesh with each other. can be
