windows

2 and 2 ′ respectively installed in front and rear of the window frame 1 are independently of each other. In the process of sliding along the sliding 1b of the window frame 1, each stop bar 42 is pressed by each plate 21 between the perforations 23 of each plate 21 at different positions to stop each stop bar. Even if the 42 is lowered by varying the descending distance, or the stop bar 42 on one side is lowered and the stop bar 42 on the other side is raised, the rotating shaft 64 is freely rotated by the connecting rod 70. This allows the lock to be performed separately without twisting.

On the other hand, when the user rotates the operation lever 62, the rotation shaft 64 is rotated integrally with the operation lever 62, and the pin 68 fixed to the rotation shaft 64 is guided by the connecting rod 70. The connecting rod 70 is also rotated while being caught by the end of the slot 76, so that the transfer block 43 connected to the connecting rod 70 is lowered. Accordingly, the stop bar 42 coupled to the transfer block 43 may be moved from the window 2 while leaving the perforation 23 of the plate 21. When the user releases the operation lever 62, the spring 48 installed below the stop bar 42 is restored, and the spring 66 installed on the operation lever 62 and the rotation shaft 64 is restored. The stop bar 42 again protrudes in the direction of the plate 21, and the operation lever 62 is also returned to its original position.

12, the window frame side locking unit 60 in the locking device 10 of the window according to the preferred embodiment of the present invention described above is made of a configuration that is manually operated by the user, in the present embodiment window frame side The locking unit 60 is provided with a driving driver such as an electromagnet for lowering the stop bar 42 and a control panel in which any one selected from a keyboard and a keypad to which a password is input is installed. The digital operation unit 61 can be additionally configured to automatically move the window 2 by lowering the stop bar 42. Of course, such a digital operation unit 61 is preferably provided with an operating mechanism that is manually operated by the user as described above to be able to operate manually in an emergency.
