Push-out Window Frame Structure with Hidden Folding Screen Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing push-out window frame structures fail to achieve optimal watertightness and airtightness due to design limitations, particularly when a folding screen is used, as they allow air flow reduction and allow outdoor dust and mosquitoes to enter.
Innovation Solution
A frame body structure for a push-out window featuring an outer frame with airtight bars that fit against a frame body when the inner leaf closes, enhancing watertight and airtight seals, and incorporating a folding screen component that can be hidden within the frame without obstructing the opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a groove is provided between the mullion frame and the inner wood-aluminum composite frame to accommodate a folding screen, then the folding screen can prevent outdoor dust or mosquitoes from entering the room, but the watertightness and airtightness of the window are compromised
Solution Approach 1:
The window frame is divided into multiple components: outer frame, inner frame, and a separately installable frame body that fits into the groove. This segmentation allows the folding screen to be accommodated in the groove while the frame body maintains the watertight and airtight seal between the inner frame and outer frame.
Solution Approach 2:
The frame body acts as an intermediary element that bridges the gap created by the groove. It is installed in the groove and provides sealing surfaces that contact both the inner frame and outer frame, thereby maintaining the watertight and airtight connection despite the presence of the folding screen accommodation groove.
2Object-affected harmful factors
If a folding screen is provided in the groove to prevent outdoor dust or mosquitoes from entering, then protection against harmful factors is improved, but the groove setting fails to maintain watertight and airtight effects
Solution Approach 1:
The window frame is divided into multiple components: outer frame, inner frame, and a separately installable frame body that fits into the groove. This segmentation allows the folding screen to be accommodated in the groove while the frame body maintains the watertight and airtight seal between the inner frame and outer frame.
Solution Approach 2:
The frame body acts as an intermediary element that bridges the gap created by the groove. It is installed in the groove and provides sealing surfaces that contact both the inner frame and outer frame, thereby maintaining the watertight and airtight connection despite the presence of the folding screen accommodation groove.
3Ease of operation
If sliding windows are used to achieve air convection and blocking outdoor dust or rain, then the benefits of window functionality are achieved, but air flow is reduced when the window is opened
Solution Approach 1:
Instead of using a sliding window where one pane blocks half the opening when opened, this invention uses a push-out window where the inner leaf is pushed outward. This inversion of the opening mechanism allows the full window opening to remain unobstructed, maximizing air flow while still providing the functionality of air convection and blocking when closed.

AI summary
Provided is a frame body structure of push-out windows, including an outer frame and an inner leaf, wherein the outer frame is at least provided with an opening, the inner leaf is pivotally connected to the outer frame and opens and closes the opening of the outer frame, a channel is provided in a closed area between the inner leaf and the outer frame, a frame body is arranged in the channel, and at least one airtight bar is provided at the outer frame and the inner leaf and attached to the protruding part of the frame body. When the inner leaf closes the opening of the outer frame, the at least one airtight bar at the outer frame and the inner leaf is able to fit into the frame body so as to enable the setting of the frame body not to affect the watertight and airtight effect.
