1 is a view showing a window lock device according to the present invention.

The window lock device 100 includes a latch 10, a latch 20, a motor 30, and a controller 40.

The latch 10 has a vertical rectangular opening 14, and the opening 14 is formed by the projection 12 of the "C" shape. The width of the opening 14 is greater than the width of the short cross section of the clasp 20. This is to allow the latch 22 to be inserted into the inner space of the latch in a vertical state. The catch 10 is inserted into the window 14 in the direction in which the opening 14 faces the window frame.

The clasp 20 is a columnar member having a longitudinal cross section and is formed with a latching jaw 22 protruding from the end thereof. The locking jaw 22 is inserted into the opening 14 of the latch 10 when the window is closed, and when the window is locked, the locking jaw 22 is opened by rotating in a direction perpendicular to the sliding direction of the window by the motor 30. The locking operation is performed by being caught by the projection 12 of 14.

The motor 30 has a rotation axis of the motor connected to the clasp 20 on the same extension line as the sliding direction of the window along the centerline of the window, and rotates the clasp 20 in a direction perpendicular to the sliding direction of the window.

The controller 40 receives an external signal input by the user and drives the motor 30.

Figure 2a is a view showing the principle that the window is locked as the operating principle of the present invention.

The glass 3 is provided in the window pair 1, and it is a state which slides in the arrow direction. The window frame 2 is mounted on the wall 4 and is fixed.

When the user slides the window pair 1 in the direction of the window frame 2 to close the window, the latch 20 is inserted into the opening 14 of the latch 10. At this time, since the clasp 20 is not rotated yet, the long cross-section direction of the clasp 20 is located in the longitudinal direction, which is an extension direction of the opening 14 of the clasp, and as a result, the clasp is easily inserted into the opening 14 of the clasp. Can be inserted. After that, when the latch 40 is rotated by 90 degrees by the controller 40 driving the motor 30 by an external signal, the direction of the long cross section of the latch is the direction perpendicular to the extending direction of the opening 14 of the latch. Direction, and as a result, the latching jaw 22 of the latch 20 is caught by the projection 12 of the latch so that the window is locked.

Figure 2b is a view showing the principle that the volume of the window lock device is attenuated as the operating principle of the present invention.

As shown in FIG. 2B, the axis of rotation 32 of the motor is located along the centerline of the window on the same extension line as the sliding direction m1 of the window. Therefore, the rotating shaft of the motor and the motor for performing the locking operation can be easily inserted into the window frame.

Conventional annular window locks require a lot of space for the operation of the window lock because the movement of the hook for the window lock is perpendicular to the sliding direction of the window. It was not easy to insert.

However, in the present invention, since the rotation shaft for rotating the latch is positioned on the same extension line as the sliding direction of the window, the space occupied by the motor and the rotation shaft 32 of the motor is selected in the length l direction rather than the window width or the width w of the window frame. It is easy to insert the locking device into the window frame and the window frame. (If the movement of the member for locking action requires a large copper wire in the direction perpendicular to the window sliding direction, as in the conventional annular locking device, the locking device Will become bulky and as a result it will not be easy to insert inside).

In this case, the rotation shaft 32 of the motor during the operation for locking the window rotates in a direction m2 perpendicular to the sliding direction m1 of the window so that there is no problem in performing the window locking operation. Since the copper wires are within a range smaller than the width w of the window frame and the window frame, no additional installation space is required.

In addition, the increase in volume due to the latching jaw 22 of the clasp (2 mm to 5 mm in the width w direction) is much smaller than the difference between the width of the existing window sill and the width of the window locking device, thus increasing the volume due to the locking jaw. Is not required, and as a result, it is not a problem to insert the window lock into the window.

After generating and transmitting to the control unit 40, the control unit 40 operates the user alarm unit when receiving the open signal in the state that the open command signal is not received from the open remote device (60). In one embodiment, the user alarm unit 70 is an alarm light or a buzzer. Since there is a play between the clasp 20 and the catch 10 even when the latch 20 is locked, the closing detection unit may select the proximity sensor even in the locked state by appropriately selecting the reference distance of the proximity sensor into the play. It is possible to generate the open signal by using.

According to the present embodiment, when the closed detection unit 60 detects that the window is opened while the window is not commanded to open by the open remote device 80, the user alarm unit 70 operates, thereby invading the intruder. When you deliberately try to open the window, an alarm is activated to give the user an appropriate warning.

4A and 4B illustrate another embodiment of the present invention.
