Hereinafter, an operation of the locking device 100 according to an embodiment of the present invention will be described with reference to FIGS. 5 to 10 .

The locked state of the locking device 100 will be described in more detail with reference to FIG. 5 .

In the locked state of the locking device 100 , the hook portion 179 is releasably coupled to the corresponding portion 903 of the striker 901 so that the locked state of the windows and doors can be maintained. The locking groove 177 is formed in a shape that can be matched with the locking protrusion 157 , and may be releasably fixed. Since the locking groove 177 and the locking protrusion 157 are matched with each other and maintained in a fixed state, the hook portion 179 and the corresponding portion 903 of the striker 901 may be fixed to each other so as not to be released.

Referring to FIG. 8 , coupling and release of the striker 901 and the hook part 179 will be described in more detail. Illustratively, the striker 901 includes a corresponding portion 903 formed in a predetermined shape on the side surface. As the locking member 170 rotates around the locking member fixing part 171 , the corresponding part 903 may be releasably coupled to the hook part 179 . In a state in which the coupling of the hook portion 179 of the locking member 170 and the corresponding portion 903 of the striker 901 is released (shown by a dashed-dotted line), the striker 901 moves in a predetermined direction (upper side in FIG. 8 ). Since it can move to, the window frame 905 is relatively spaced apart from the locking device 100 so that the window can be opened.

The unlocking operation of the locking device 100 will be described in more detail with reference to FIGS. 6 and 7 . The locking device 100 in the locked state may be released by rotating a handle (not shown) connected to the rotating part 112 . The handle (not shown) may be fixed to the rotating shaft hole 111 of the rotating part 112 in a form-coupled manner. When the handle (not shown) is rotated clockwise, the entire operating gear 110 including the rotating part 112 may be rotated clockwise around the rotation shaft hole 111 . When the gear protrusion 117 of the actuating gear 110 rotates clockwise, the slide part 151 of the slide member 150 is pressed while in contact with the gear protrusion 117 in the direction in which the slide elastic member 157 is compressed ( 6) is pushed and moved.

Accordingly, the entire slide member 150 may move in the above direction (downward in FIG. 6 ). When the locking protrusion 157 of the slide member 150 moves in the above direction (downward in FIG. 6 ) and the locking protrusion 157 and the locking groove 177 are released, the elastic force of the locking elastic member 175 is released. Due to this action, the locking member 170 may be rotated clockwise around the locking member fixing part 171 .

When the entire locking member 170 is rotated clockwise, the coupling between the hook portion 179 and the corresponding portion 903 is released. Since the locking elastic member 175 provides an elastic force to maintain the locking member 170 rotated in the clockwise direction, the locking member 170 is rotated while the elastic force of the locking elastic member 175 is maintained. can be maintained

On the other hand, when the actuating gear 110 is rotated clockwise, the actuating gear connecting part 113 and the arm coupling part 115 formed at one end of the actuating gear connecting part 113 are also rotated clockwise. The arm coupling part 115 may transmit the rotational force of the actuating gear 110 to the push arm 130 while linearly moving along the interlocking groove 135 of the push arm 130 .

Accordingly, when the actuating gear 110 is rotated in a clockwise direction, the push arm 130 rotating around the arm fixing part 131 may rotate in a counterclockwise direction. Accordingly, the roller 139 may protrude to the outside (the right direction in FIG. 6 ) of the case 101 to separate the striker 901 or the window frame 905 . Since the arm coupling part 115 is disposed between the arm fixing part 131 and the roller 139 to transmit rotational force, the moving distance of the roller 139 can be more efficiently adjusted using the principle of the lever. By adjusting the length and position of the interlocking groove 135, the moving distance of the roller 139 and the force that separates the striker 901 or the window frame 905 can be adjusted.

By adopting such a structure of the push arm 130, a part of the rotational force of the actuating gear 110 may be transmitted to the push arm 130, and the striker 901 or the window frame 905 may be spaced apart by a predetermined distance.

Meanwhile, with reference to FIG. 9 , coupling and release of the locking protrusion 157 and the locking groove 177 will be described in more detail. In a state in which the locking protrusion 157 and the locking groove 177 are matched (shown by a dashed-dotted line), the elastic force of the slide elastic member 157 acts in a predetermined direction (the left side of FIG. 9 ) to form the slide member 150 and The locking grooves 177 can maintain registration, thereby preventing the locking member 170 from rotating in either direction.

However, when the slide member 150 moves in a predetermined direction (the right side of FIG. 9 ) and the mating with the lock groove 177 is released (shown by a solid line), the elastic force of the lock elastic member 175 is applied to the lock member. 170 rotates clockwise around the lock member fixing part 171 . When an external force is not applied to the locking groove 177 in the rotated state, registration with the locking protrusion 157 cannot be made again.

For example, when the locking member 170 is rotated counterclockwise by receiving an external force in the coupling process with the striker 901 and the locking groove 177 is positioned at a predetermined position, the elastic force of the slide elastic member 157 is used. As a result, the slide member 150 can move in a predetermined direction (the left side of FIG. 9 ), and the locking protrusion 157 is again aligned with the locking groove 177 .

Although the shape of the locking protrusion 157 and the locking groove 177 can be changed in various designs, the shape of the locking groove 177 should be formed to restrict the movement of one side of the locking protrusion 157 . In this embodiment, a locking groove 177 having an exemplary right-angled shape is formed and matched with the locking projection 157 having a rectangular protruding shape, so that the locking projection 157 moves in a predetermined direction (left side of FIG. 9 ). limit what you do Due to this, registration between the locking protrusion 157 and the locking groove 177 may be maintained.

Meanwhile, with reference to FIG. 10 , the interlocking of the interlocking groove 135 and the arm coupling part 115 will be described in more detail. The interlocking groove 135 is formed in the longitudinal direction of the push arm 130 so that the arm coupling part 115 can relatively reciprocate linearly. The width of the interlocking groove 135 and the thickness of the arm coupling portion 115 are preferably formed to be substantially the same as each other. In addition, the arm coupling portion 115 is preferably formed to protrude in a cylindrical shape for smooth interlocking. When the roller 139 is completely accommodated inside the locking device 100 case 101 (shown by a solid line), the arm coupling part 115 is located at one end of the interlocking groove 135 closest to the arm fixing part 131 . will be located

On the other hand, in a state in which the roller 139 protrudes as much as possible (shown by a dashed-dotted line), the arm coupling part 115 is positioned at the other end of the interlocking groove 135 furthest from the arm fixing part 131 . By adopting this structure, the arm coupling part 115 moves relatively linearly between one end and the other end of the interlocking groove 135, but in an absolute point of view, it moves along a circular arc (shown by a solid arrow line) so that the roller 139 moves. It may protrude to the outside of the case 101 . In the process of starting the unlocking, the arm coupling part 115 receives the rotational force of the actuating gear 110 from the position closest to the arm fixing part 131 and starts to move. Accordingly, the rotational force of the actuating gear 110 can be more efficiently transmitted to the roller 139 in the initial unlocking operation that requires a lot of force.

On the other hand, when the locking operation is performed due to the coupling of the corresponding part 903 and the hook part 179 of the striker 901, the striker 901 presses the hook support part 173 and the locking member 170 is half It can rotate in a clockwise direction (a direction opposite to the direction of the elastic force applied through the locking elastic member 175 ). When the locking protrusion 157 and the locking groove 177 are matched and fixed by rotating the locking member 170 counterclockwise, the coupling between the corresponding portion 903 of the striker 901 and the hook portion 179 is maintained. can Accordingly, the locking operation of the window can be completed.

When a large amount of force is temporarily required in the process of unlocking the window (for example, the window itself is heavy, insufficient lubrication, frost, etc.) Therefore, it is possible to help a user, such as an elderly person who is relatively weak in muscle strength, to easily perform an unlocking operation of the locking device.

In addition, since the unlocking of the locking device can be completed only by sufficiently rotating the handle, the user's operation can be simplified. Accordingly, when the user wants to open the window in a state in which the unlocking of the locking device is not completed due to a user's error, it is possible to prevent deterioration of durability that may occur due to an unnecessary external force applied to the handle or the locking device.

It is to be understood that the above-described embodiments are illustrative in all respects and not restrictive, and the scope of the present invention will be indicated by the appended claims rather than the foregoing detailed description. And it should be construed to be included in the scope of the present invention, as well as the meaning and scope of the claims to be described later, as well as all changes and modifications derived from the equivalent concept.
