In addition, the embodiments described below do not unduly limit the contents of the present invention described in the claims, and the entire configurations described in the embodiments of the present invention are not necessarily essential as means for solving the present invention.

The locking device of the window according to the embodiment of the present invention can securely lock or operate the window securely even when the window is opened, thereby improving the safety.

2 to 3, the locking device of the window 210 according to an embodiment of the present invention is as follows.

A slider bracket 110 is provided at a bottom corner of a window 210 installed to slide left and right on a window frame 200. The slider bracket 110 is formed to fasten the main roller 120 which can slide the window 210 in the left and right directions on the rail 201 of the window frame 200. The main roller 120 is supported by a main roller pin 111 which passes through the main roller 120 and is engaged with a roller groove (not shown) in a roller groove (not shown) formed on the center side of the slider bracket 110 And is fastened to the slider bracket 110.

A braking portion 130 capable of braking the main roller 120 is fastened between the slider bracket 110 and the main roller 120.

A braking member 113 for applying pressure to the brake unit 130 is formed at one side of the slider bracket 110 so as to contact the brake unit 130 with the main roller 120. A detailed description of the braking member 113 will be described later.

The window handle 140 formed on one side of the window 210 and the release button 141 pressed on the inside of the window handle 140 each time the window handle 140 is pushed right and left can be disposed. The release button 141 may be operated to raise and lower the connection link which is fastened to the lower end of the window handle 140.

That is, the release button 141 can be operated to switch the horizontal motion to the vertical motion while being pressed each time the window handle 140 is pushed to the left and right. Thus, while the release button 141 is pressed, the horizontal movement is switched to the vertical movement, so that the connection link 150 fastened to the lower end of the window handle 140 can be raised and lowered.

Or the release button 141 may be operated to switch the rotary motion to vertical motion while being pressed each time the window handle 140 is pushed to the left and right. Thus, while the release button 141 is being pressed, the rotary motion is switched to the vertical motion, so that the connection link 150, which is fastened to the lower end of the window handle 140, can be raised and lowered.

Or the release button 141 may be pressed each time the window handle 140 is pushed to the left or right to generate a direct vertical motion. In this way, the vertical movement allows the connecting link 150, which is fastened to the lower end of the window handle 140, to be moved up and down.

As described above, the release button 141 is operated to separate the brake unit 130 and the main roller 120 in a state where the connection link 150 is lifted and brought into contact with each other.

Here, one end of the connecting link 150 is fastened to the lower end of the window handle 140, and the other end can be fastened to the brake unit 130 or the braking member 113. As described above, the connecting link 150 to be fastened is configured such that one end is raised and lowered while the user pushes the window handle 140 to the left and right, and the other end is pulled by the other end as much as the length of the one- The brake unit 130 and the main roller 120, which are in contact with each other and are in a braked state, can be separated from each other. The window 210 moves while sliding along the rail 201 in the left and right directions while the release button 141 formed on the inside of the window handle 140 is pressed, 210 may not move in a braked state.

It is preferable that at least one roller guide 153 is formed between the window handle 140 and the brake part 130 so that the connection link 150 can smoothly operate within one side of the window 210. The roller guide 153 is formed to rotate in the first direction or the second direction. That is, the roller guide 153 is disposed in contact with the connection link 150, and can perform a rotation operation whenever the connection link 150 moves in the left-right direction or the up-down direction. As described above, since the roller guide 153 rotates and assists the movement of the connection link 150, the connection link 150 can be easily operated even with a small force.

Further, the connection link 150 may be formed of a wire, a thin wire, or the like. Since the connection link 150 is formed of a wire or a thin wire or the like in this way, the brake unit 130 can be easily controlled with a simple structure, so that the window 210 can be braked or the brake window 210 can be released have.

Referring to FIG. 3, a side view of the laminating apparatus of the window 210 according to the embodiment of the present invention is shown.

The main roller 120 is formed in a cylindrical shape due to a bottom surface thereof. The central region is recessed to abut against the rail 201 of the window frame 200 to rotate. That is, the main roller 120 may be formed in a shape of a mortar with a concave central region.

The braking portion 130 is formed so that the central region thereof protrudes convexly to correspond to the main roller 120 having a concave central region. As a result, the area in contact with the main roller 120 is increased, so that the main roller 120 can be more easily braked.

Here, it is preferable that the brake portion 130 is formed of a material containing soft or elastic force. As described above, since it is formed of a material containing soft or elastic force, the area of contact with the main roller 120 is increased, and the braking performance can be improved.

3, the central region of the braking portion 130 is protruded and protruded. However, the present invention is not limited thereto, and any shape may be used as long as the main roller 120 can be braked.

Although not shown, the side surfaces where the main roller 120 and the brake portion 130 abut each other may be formed in a gear shape.

3, the through pins 151 disposed through the brake 130 are fastened to the connection link 150. However, the present invention is not limited thereto, and the connection link 150 and the brake unit 130 may be rigid Any structure or shape may be used as long as the brake portion 130 can be separated from the main roller 120 while being fastened to the main roller 120. [

In addition, the braking member 113 operates to contact the main roller 120 by applying a predetermined pressure to the braking unit 130, thereby preventing the main roller 120 from sliding left and right. At this time, the braking member 113 is preferably formed of a resilient material, and most preferably, it is formed of a leaf spring.

This braking member 113 can be firmly fastened to the connecting link 150, though not shown. Accordingly, when the connection link 150 operates, it is possible to release the application of the constant pressure to the brake portion 130. [ A detailed description thereof will be described later.

Referring to FIGS. 4 and 5, operation of the window handle 140 and the connection link 150 according to an embodiment of the present invention is shown.

4 shows the state before the release button 141 of the window handle 140 is operated.

The release button 141 may be connected to the rotation roller 141b disposed inside the window handle 140 via the connection bar 141a. If the release button 141 is not pressed, the rotation roller 141b connected to the connection bar 141a does not rotate.

If the rotation roller 141b is not rotated, the main roller 120 and the brake unit 130 can be kept in contact with each other since the connection link 150 is not moved up and down. Thus, the main roller 120 can be continuously braked. Therefore, the window 210 does not slide left and right.

5 shows that the release button 141 of the window handle 140 is operated.

When the release button 141 disposed on the inner side of the window handle 140 is pressed, the connection link 150 mechanically connected to the window handle 140 can move up and down. That is, when the release button 141 is pressed, the rotation roller 141b connected to the connection bar 141a rotates.

When the rotation roller 141b rotates as described above, since the connection link 150 is lifted and lowered, the main roller 120 and the brake 130 can be separated from each other. Thereby, the braking of the main roller 120 can be released. Therefore, the window 210 can slide in the left and right direction.

Although the left release button 141 is shown here to be depressed, the same operation can be performed even if the release button 141 on the right side is pressed.

In addition, the window handle 140 may be operated by forming a release button 141 on the left or right side.

A detailed description of the lifting and lowering of the connection link 150 by depressing the release button 141 has been fully described above, and thus will not be described here.

Referring to FIG. 6, operation of the braking member 113 and the brake unit 130 according to an embodiment of the present invention is shown.

6 (a) shows that the braking member 113 continues to apply pressure to the brake portion 130. As shown in Fig. That is, since the braking member 113 has elasticity, it is possible to apply pressure to the braking unit 130 so that the braking unit 130 can contact the main roller 120 continuously.

By applying the pressure in this manner, the main roller 120 is braked because the brake portion 130 and the main roller 120 are in contact with each other continuously. As a result, the window 210 does not slide in the lateral direction.

6B shows a state in which the braking member 113 continues to apply pressure to the braking unit 130 and the braking unit 130 and the main roller 120 are separated from each other by the ascending and descending operations of the connecting link 150 . That is, since the force for pulling the braking member 113 or the braking unit 130 by the lifting and lowering operation of the connecting link 150 is greater than the force by which the braking member 113 applies pressure to the braking unit 130, (130) is separated from the main roller (120) to release the braking of the main roller (120). Thus, the window 210 can slide in the left and right direction.

The locking device of the window 210 according to the embodiment of the present invention described above does not press the releasing button 141 of the window handle 140 until the brake unit 130 continuously brakes the main roller 120 The window 210 can not slide left and right. By operating in this way, the window 210 can be firmly locked without a separate locking device even when the window 210 is opened.

That is, if the release button 141 of the window handle 140 is not pressed, the brake 130 is operated continuously, so that even if a part of the window 210 is opened, the door can be easily locked.

Therefore, not only a separate locking device of the window 210 is unnecessary, but also a security function can be easily performed.

In addition, since there is no separate locking device, it is possible to easily solve the problem that the lock devices protruding from the existing window 210 are less likely to be pushed by the locking devices, or the lock devices protruding from the window 210 are hit by each other .

Although the present invention has been described with reference to the embodiment thereof, the present invention is not limited thereto, and various modifications and applications are possible. In other words, those skilled in the art can easily understand that many variations are possible without departing from the gist of the present invention.
