Window

Abstract

The invention relates to a window. The window is provided with a window frame, a sash and a first operation device; the window frame is fixed to a building; the sash is rotatably mounted on the windowframe and is provided with a sash frame on the periphery; the sash frame is formed by a pair of first frames opposite to each other and a pair of second frames opposite to each other; the first operation device is provided with long connecting rods rotatably fixed to the first frames, short connecting rods rotatably fixed to the first frames and slidably connected to the long connecting rods, andfirst operation parts arranged on the long connecting rods for opening and closing the window. According to the window, the leaning distance can be reduced to ensure safety and the force point distance can be lengthened to facilitate operation.

Description

technical field [0001] The present invention relates to a window. Background technique [0002] For a long time, the windows used in our daily life have various types of opening and closing, for example, there are casement windows that can slide parallel to each other on the window frame, and sliding windows that can be rotated indoors or outdoors to open. [0003] The opening and closing of the sliding window is mainly carried out through the multi-link supports or hinges connecting the window frame and the sash frame. [0004] Whether multi-link supports or hinges are used, one of the two mullions of the sash is close to the frame and the other opens outward. Thus, when opened, the other mullion of the sash is set away from the window frame. [0005] When we usually use the window, we need to close the window. Therefore, we need to close the sash frame away from the window frame, that is, the other mullion of the sash. out of the body. [0006] Therefore, a kind of aux...

Problems solved by technology

like figure 1 As shown, when the sash is opened, the auxiliary device is closer to the window frame than the normal handle, and its operating distance (body leaning distance) is about 500mm, which is relatively small. However, since the force point distance is the same as the operating distance (body leaning distance), it is also about 500mm , therefore, the force point distance is small, requiring a relatively large operating force, which makes the operation laborious

In the case of reducing the operating force and keeping the auxiliary device farther away from the window frame, the operating force can be reduced, but the operating distance (body detection distance) is increased, which is more dangerous
