Description

Doors and windows and their latching devices

The present invention relates to a door and window and operating parts, in particular to a door and window and a latch device thereof.

All buildings have doors and windows designed to provide lighting, ventilation, outdoor viewing, and indoor air circulation. However, the sash of doors and windows must be able to be locked and unlocked so that the sash of doors and windows can be opened or closed. Please refer to Figure 1 and Figure 2, which is an existing door and window device 1, including a frame surrounding an installation space. The installation space of the frame has two window sashes that slide relative to each other, and are provided with opening and closing functions. The operating module 13 of the window sash is provided with corresponding positioning members 14 on both sides of the frame. When the window sash is opened and closed, the operating module 13 is used to cooperate with the positioning members 14 provided on both sides of the frame. The positioning member 14 (only one side of which is shown in Figure 1) is used for locking and unlocking so that the operating module 13 operates the window sash to open and close. Among them, the operation module 13 includes a pull rod 131 that extends laterally for holding, two locking parts 132 located at opposite ends of the pull rod 131 and used to engage with the positioning parts 14 respectively, and two locking parts 132 .
