A four-way opening casement window linkage device

Abstract

The invention provides a linkage device for a casement window capable of being opened in four directions, belongs to the technical field of casement windows, and aims at solving the technical problem of complex opening process of the existing casement window capable of being opened in four directions. According to the technical scheme, the linkage device for the casement window capable of being opened in four directions comprises bases which are mounted at corners of a sash and respectively fixedly connected with two adjacent sides of the sash; linkage assemblies are arranged on the bases; two ends of the linkage assemblies are respectively connected with transmission links at two adjacent inner sides of the sash; the linkage assemblies can move on the bases and enable the transmission links at the two adjacent sides of the sash to synchronously move. The device has the beneficial effects that the sash can be conveniently and quickly opened or closed in two different directions without rotating two handles forwards and backwards, and meanwhile, the time of switching to open the sash in other directions can also be decreased, and as a result, the sash opening efficiency is raised.

Description

technical field [0001] The invention belongs to the technical field of casement windows, and relates to a linkage device, in particular to a linkage device for four-way opening casement windows. Background technique [0002] At present, the windows used in daily life are mainly casement and push-pull. Compared with sliding windows, casement windows have the advantages of large opening area, good ventilation, good sealing, sound insulation, heat preservation, and impermeability. Widely used, therefore, casement windows are better than sliding windows in performance, but because casement windows are mainly opened outwards, it is difficult to clean the outside of the sash, which often results in more dust on the sash and cannot be cleaned, seriously affecting the Therefore, people have invented a casement window that can be opened in four directions, which makes it easier to clean the window during use. [0003] This four-way opening casement window is equipped with handles an...

Problems solved by technology

[0002] At present, the windows used in daily life are mainly casement and push-pull. Compared with sliding windows, casement windows have the advantages of large opening area, good ventilation, good sealing, sound insulation, heat preservation, and impermeability. Widely used, therefore, casement windows are better than sliding windows in performance, but because casement windows are mainly opened outwards, it is difficult to clean the outside of the sash, which often results in more dust on the sash and cannot be cleaned, seriously affecting the Therefore, people invented a casement window that can be opened in four directions, which makes the window easier to clean during use

[0003] This four-way opening casement window is equipped with handles and fixing pins on the upper, lower, left, and right sides of the window sash, and the inside of the four window sides is equipped with transmission links connected with corresponding handles, and the transmission links are connected with the fixing pins. , turn the handle, through the transmission of the transmission link, the fixed pin on each window edge can form a fixed connection state with the window frame, and the other three sides can be opened, so that each side of the sash can be opened, thus, This four-way casement window is more convenient to use in daily life and easier to clean, but it also has the following technical problems at the same time, each handle and transmission link only control one of the sides of the window sash, and the window sash only The fixing pin on one side is connected to the window frame, while the fixing pins on the other three sides are not connected to the window frame. When you choose to open the sash in different directions, you need to close the whole sash first, and connect the closed side of the sash to the window through the handle. Lock the frame, and then use the handle to separate the window edge that needs to be opened from the window frame, which increases the cumbersomeness of the use of the window to a certain extent, prolongs the process of opening the window, and reduces the opening efficiency of the sash
