Description

Horizontal sliding window and horizontal sliding window lower frame

This creation is related to horizontal sliding windows; in particular, it refers to a horizontal sliding window and the lower frame of the horizontal sliding window that can relieve pressure and drain water.

It is known that the horizontal sliding window is easy to operate and occupies less space when the window sash is opened than a casement window. Therefore, the horizontal sliding window has been widely adopted by users. A horizontal sliding window generally includes a window frame and two window sashes. Two parallel rails are provided on the window frame. The two window sashes are staggered and can be combined with each other in a relatively translational manner. The operation method is to push and pull the two window sashes. The two window sashes move horizontally on the track on the window frame, so that the sealing between the two window sashes and the window frame can prevent the outdoor side wind and rain from being injected into the indoor side space.

However, when the wind and rain are too strong, it is easy to cause the pressure on the outdoor side to be greater than the pressure on the indoor side to form a pressure difference. This pressure difference is likely to cause the wind and rain to penetrate into the indoor space through the window frame and the gap between the two sashes or between the two sashes. For example, when the two window sashes are located at the position of the window closing the window frame, the junction between the bottom of the two window sashes and the window frame is likely to be unable to completely block the infiltration of wind and rain caused by wind pressure. It penetrates into the room through the gap or is splashed into the room by strong wind pressure, which causes the problem of humidity and water leakage in the room. Therefore, the design of the conventional horizontal sliding window still needs to be improved.

In view of this, the purpose of this creation is to provide a horizontal sliding window that can provide drainage and pressure relief.

In order to achieve the above purpose, this creation provides a horizontal sliding window, which is installed in a building. The horizontal sliding window includes a window frame, an inner sash and an outer sash. The window frame includes a lower frame, and the lower frame includes a A first track and a second track, the first track has a first channel, a first through hole and at least one second through hole, a first slide track, the second track has a second slide track, the first The perforation and the at least one second perforation respectively communicate with the exterior space of the building and the first passage, the first slide rail is arranged on the indoor side of the building, and the second slide rail is arranged on the side of the building The outdoor side, and the first slide rail is located higher than the second slide rail at a position higher than the bottom of the lower frame; wherein the inner window sash is arranged on the first slide rail, and the outer window sash is arranged on the second slide rail And the inner window sash and the outer window sash can respectively be translated between a first position and a second position on the first slide rail and the second slide rail; wherein, the window frame has a window, the inner The sash has a first elevation, and the outer sash has a second elevation. When the inner sash is at the first position and the outer sash is at the second position, the inner sash and the outer sash close the window and The first elevation faces the upper section of the second elevation, and the first perforation faces the lower section of the second elevation.

The lower frame of the horizontal sliding window provided by this creation is set in a building for setting an inner sash and an outer sash. The lower frame of the horizontal sliding window can be enclosed with an upper frame to form a window. The inner window sash has a first elevation, the outer window sash has a second elevation; the lower frame of the horizontal sliding window includes a first track and a second track, and the first track has a first channel and a second track. A perforation, at least one second perforation and a first slide rail, the second rail has a second slide rail, the first perforation and the at least one second perforation respectively communicate with the exterior space of the building and the first passage , The first slide rail is installed on the indoor side of the building, the second slide rail is installed on the outdoor side of the building, and the first slide rail is higher than the second slide rail The position of the bottom of the lower frame of the horizontally drawn window; wherein the inner window sash is arranged on the first slide rail, the outer window sash is arranged on the second slide rail, and the inner window sash and the outer window sash can respectively slide on the first On the rail and the second slide rail to translate between a first position and a second position; when the inner sash is at the first position and the outer sash is at the second position, the inner sash and the outer sash are The window is closed and the first elevation faces the upper section of the second elevation, and the first perforation faces the lower section of the second elevation.

The effect of this creation is that when the horizontal sliding window is exposed to greater wind pressure on the outdoor side, the airflow from the building’s exterior space can enter the first passage from the first perforation of the lower frame, and then from the at least one second Perforated discharge, or enter the first channel of the lower frame from the at least one second perforation, and then discharge from the first perforation to quickly disperse the wind pressure on the outdoor side of the horizontal sliding window. In this way, Improve the problem that the gaps of conventional horizontal sliding windows cannot completely block the infiltration of wind and rain caused by wind pressure, so that the wind and rain can penetrate into the room through the gap or be splashed into the room by strong wind pressure. In addition, through the setting position of the first perforation, the effect of quickly dispersing the wind pressure at the junction between the bottom of the overlap of the inner sash and the outer sash and the lower frame can be achieved.
