Abstract

The invention relates a sash window. It includes the characters of arranging the top ends of railway parts of a bottom frame and the top surfaces of gap components installed between the railway parts at the about same height, able to make the top surface of the bottom frame be a plane, thus able to be made into a sash window suitable for obstacle-free type, and arranging about horizontal top surface part on the gap components so as to be able to reduce the widths of the grooves formed between the railway parts, thus improving the plane sense; besides, taking down the gap components to enlarges the gaps between the window sash pulley guide parts, able to clean between the railway parts without taking them down, and unnecessary to care about the falloff of the moving window as cleaning, able to be secure to make cleaning, and thus able to provide a sash window applied to an obstacle-free window and able to prevent the moving window falling off as cleaning and able to smoothly close and open the moving window.

Description

technical field [0001] The invention relates to sash windows such as double sliding windows and single sliding windows. Specifically, it relates to a sash window used in a barrier-free sweep-out window in which the upper surface of the lower frame is substantially flat, and the step difference with the upper surface of indoor and outdoor floor materials is reduced. Background technique [0002] On the outer wall positions facing terraces, balconies, etc. of houses, etc., sweep-out windows for occupants to enter and exit from indoors to balconies, etc. are provided. As such a sweep-out window, there are usually a double sliding window and a single sliding window having a window frame fixed to an outer wall and a movable window slidably supported in the window frame. [0003] In these double sliding windows and the like, the guide rails for guiding the sash pulleys provided in the lower sash frame of the sliding window are formed in a shape pro...

Problems solved by technology

[0007] However, in the lower frame structure described in the above-mentioned Patent Document 1, when the molding material functioning as a guide rail is removed to clean the inside of the lower frame body, once the sliding window is mistakenly moved to the side after the molding material is removed, If it is moved, the sash pulley may come off the wheel and the window will fall off

In addition, when cleaning, the occupants must install and remove the molding material panels. If they are not installed correctly, there is a possibility that the opening and closing operation of the sliding window will be hindered.
