Window

Abstract

The invention discloses a window, which aims at resolving the problem that a middle sash of an existing profile window is limited when being opened. The window is composed of a rectangular window frame and more than two rectangular sashes disposed in the window frame. Two guide strips of a front guide strip and a rear guide strip are respectively arranged on the inner sides of the upper border and the lower border of the window frame, a guide groove is formed between every two guide strips, and the sashes are arranged in the guide grooves. The sashes at least comprise a head sash and a tail sash, and a containing chamber capable of containing the sash is arranged on the rear side of the window frame corresponding to one side of the tail sash. A spring is disposed between the inner side wall of the containing chamber and the rear side wall of the tail sash. Sash frames adjacent to the head sash and the tail sash are of complementary wedge-shaped guide structures. Depending on the wedge-shaped guide structures, the head sash is capable of extruding the tail sash in the containing chamber under the action of external force towards the tail sash. By means of the structures, a plurality of sashes can be contained in the containing chamber, and the windowing amount of the window can be increased on the premise of not increasing the width of a guide rail. The window is simple in entire structure and convenient to use.

Description

technical field [0001] The present invention relates to a window. Background technique [0002] With the continuous improvement of the processing level, most of the existing windows are made of profiles. This kind of window is convenient and quick to make, and can be customized in large quantities, so it has been recognized by the market.
