Windows and their wind braces

Abstract

The invention relates to a window and a wind brace thereof. The end portion of a connecting rod is rotatably connected to a window frame, and a positioning piece is connected to the window frame. When the window is in a closed state, an elastic piece locks a locking hook of the locating piece in an insertion hole, the window frame is opened, and a slide block moves toward the locating piece; when the slide block props against the locking hook, one part of the locking hook is pushed out of the insertion hole; when a slot in the slide bock is aligned to the insertion hole, under the restoring force of the elastic piece, the locking hook will be locked in the slot to limit movement of the slide block so as to fix the position of the window frame. When the window is closed, a handle is rotated to drive an unlocking block to move linearly. When the unlocking block props against a driving portion of the locating piece, the locating piece will be driven to rotate, so that the locking hook is separated from the slot to remove limit of the locking hook on the slide block, and the window frame is pulled back inward to close the window. Therefore, the window and the wind brace thereof are quite simple and convenient to operate. The window can be only closed by rotating the handle, so that even if in high wind weather, the window is not forced to be closed as a result of wind force, and therefore, the safety of the window is greatly improved.

Description

technical field [0001] The invention relates to the technical field of doors and windows, in particular to a window and its wind brace. Background technique [0002] To keep the windows open, there are wind braces on the hung windows. The traditional wind brace mainly adopts the rotating limit structure to realize the opening and closing of the window. When the window is opened, the window sash is pushed out to the maximum angle, and the limit structure extends out of the profile plate. After the window returns a certain distance inward, the wind brace can Support the window sash, and when closing the window, push the window sash outward to the maximum angle, the limit structure rotates and withdraws from the profile plate, and then pulls the sash back inward to close the window. There are generally two wind braces, which are respectively arranged on both sides of the window sash, and the wind braces on both sides need to move synchronously to realize the opening and closin...

AI Technical Summary

Problems solved by technology

When opening or closing the window, the limit structures on both sides of the sash are easily misaligned, resulting in the inability to open or close the window smoothly

Moreover, when encountering strong winds, the window sash is easy to move outward under the influence of the wind, so that the window is forced to close, and even the window sash may be smashed, which is very dangerous.
