Window Sash Pivot Fitting Relocation for Functional Element Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door windows face challenges in accommodating functional elements on the lower frame spar without interfering with the arrangement of rotating fittings, particularly when these fittings are designed as hidden fittings in the closed state.
Innovation Solution
The support arm of the rotating fitting is fixed above the functional element on the horizontal sash frame spar, allowing functional elements like floor seals to be accommodated without collision, and a drainage system is integrated with a water barrier that redirects water outside, facilitating easy installation and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the rotating fitting is designed as a hidden fitting in the closed state, then the aesthetic appearance is improved, but the accommodation of functional elements on the lower frame spar becomes more difficult
Solution Approach 1:
The patent relocates the rotating fitting from the lower frame spar to the upper frame spar, utilizing vertical space dimension. This allows functional elements to be accommodated on the lower frame spar without spatial conflict, while the rotating fitting remains hidden in the closed state by being positioned in the upper region where it can be concealed within the fold between sash and frame.
2Adaptability or versatility
If functional elements are accommodated towards the frame on the lower frame spar, then the functionality is improved, but the arrangement of rotating fittings is interfered with
Solution Approach 1:
The patent divides the window frame into distinct functional zones: the upper frame spar accommodates the rotating fitting, while the lower frame spar is dedicated to functional elements like floor seals and drainage. This spatial segmentation eliminates interference between components and simplifies the overall arrangement by assigning specific regions for specific functions.
3Reliability
If the support arm is fixed above the functional element on the horizontal sash frame spar, then the collision between functional elements and rotating fitting is avoided, but the structural complexity increases
Solution Approach 1:
The patent extracts the rotating fitting from its traditional position on the lower frame spar and relocates it to the upper frame spar. This extraction eliminates the collision problem between the rotating fitting's support arm and functional elements on the lower frame spar, while the relocated fitting maintains all necessary functions without adding structural complexity.

AI summary
A window, in particular a door window, with a frame and a sash (100) rotatably and/or tiltably attached thereto, the sash frame (101) and preferably a surface element (102) received in the sash frame (101), wherein the sash frame is composed of several sash frame mullions (103-106), wherein at least one functional element (121) is arranged on a lower horizontal sash frame mullion (104) with which a lower gap to the frame is bridged, and with fittings (300) for pivotally and/or tiltably coupling the sash (100) to the frame (101), at least one of which is designed as a pivot fitting (300) for rotatably opening the sash about a vertical axis of rotation and is arranged in a lower corner of the window between the frame and the sash, is characterized by the following:that the pivot fitting (300) is held on the lower horizontal sash frame member (104) by at least one preferably horizontally oriented support arm (306), and that the support arm (306) of the pivot fitting is fixed vertically above the functional element (121) on the horizontal lower sash frame member.
