Description

Technical Field

[0001] The utility model relates to the technical field of door and window stiles, in particular to a suspended door and window reinforced stile. Background Art

[0002] The reinforced center stile in floating doors and windows is an important component for improving the overall strength and stability of doors and windows. The reinforced center stile effectively shares the force on the door and window frames by increasing the support points of doors and windows. During the opening and closing process of doors and windows, the reinforced center stile can reduce shaking and vibration, and improve the stability and safety of doors and windows.

[0003] Existing reinforced muntins are generally directly extruded as a whole, or installed on the door and window muntins in the form of an external backpack for reinforcement. In order to facilitate disassembly, external backpack-type reinforced muntins are generally used. In order to improve the aesthetics, decorative panels are also installed on the outside. The current method of installing decorative panels is generally to install them by bolts or glue. The former will expose the bolts on the surface, which is not very beautiful, and the latter is prone to debonding and falling off due to long-term wind and sun exposure. Therefore, further improvements can be made. Utility Model Content
