AI Technical Summary

Technical Problem

The existing frame structures for casement windows and sliding windows are not interchangeable, resulting in high costs for customers when changing window types, heavy inventory pressure for dealers, and an inability to flexibly switch between usage methods.

Method used

Design a universal structure for the outer frame, horizontal stiles, and vertical stiles. By adapting the first connecting part to the second connecting part of the horizontal stile and the third connecting part of the vertical stile, the casement window and the sliding window can be freely switched. The outer frame can be fitted with the horizontal and vertical stiles to install either a casement window or a sliding window.

Benefits of technology

It enables flexible switching of door and window structures, reduces the cost for customers to change window shapes, reduces the inventory pressure on dealers, and improves structural strength and aesthetics.

Abstract

This invention discloses a switchable casement and sliding door / window structure and its installation method. The door / window structure includes an outer frame with a first connecting portion; a horizontal stile, horizontally positioned within the outer frame and having a second connecting portion conforming to the first connecting portion; at least one vertical stile, vertically positioned within the outer frame and working with the horizontal stile to divide the outer frame into multiple installation areas; a casement frame, detachably installed in any installation area and connected to the first and second connecting portions respectively via opening hardware; and a sliding frame, detachably installed in any installation area, with its outer wall connected to the first and second connecting portions respectively. The casement frame and the sliding frame can be installed selectively; when the casement frame is installed, a casement door / window structure is formed; when the sliding frame is installed, a sliding door / window structure is formed. Therefore, the door / window structure can be changed by simply replacing parts, allowing users to freely switch the installation form of the door / window structure according to their needs.
