Snap-Together Sash Profiles With Integrated Glass Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional window and door frames with glazing beads create unsightly gaps and joints that accumulate dirt, detracting from the overall appearance and requiring contact pressure to secure glass elements.
Innovation Solution
A two-part sash profile system comprising an outer and inner plastic wing profiles that snap together, eliminating the need for separate glazing beads by forming a seamless optical appearance and using interlocking mechanisms to secure glass elements without additional contact pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate glazing beads are used to fix glass elements, then glass retention is achieved, but gaps and joints are created that accumulate dirt and detract from appearance
Solution Approach 1:
The patent merges the glazing bead function with the inner wing profile by integrating a glass stop directly into the inner profile structure. This eliminates separate glazing beads and their associated gaps, creating a seamless appearance while maintaining glass retention through the integrated glass stop that contacts the glass element along its length
2Ease of manufacture
If glazing beads are inserted from above into upward-facing grooves, then glass elements can be fixed, but disruptive gaps and joints appear on visible surfaces
Solution Approach 1:
Instead of inserting glazing beads from above into upward-facing grooves (conventional approach), the patent inverts the approach by having the glass stop form as an integral part of the inner wing profile that extends downward to contact the glass element. This inversion eliminates the need for separate beads inserted into grooves, achieving both ease of manufacture and seamless appearance
3Reliability
If conventional glazing bead construction is used, then glass elements are secured, but contact pressure is required which complicates the structure
Solution Approach 1:
The patent combines the structural support function and glass retention function into a single integrated inner wing profile with an incorporated glass stop. This eliminates the need for separate glazing beads that would require contact pressure, reducing structural complexity while maintaining reliable glass element security through the integrated design

AI summary
The invention relates to a sash profile (20, 30) for the frame of a window or door comprising a hollow plastic profile with an outer glass stop (23), a glass rebate surface (21) and an inner glass stop (33), which together define a glass rebate into which a filling element, in particular a glass element, can be inserted, wherein the hollow plastic profile is formed by an outer sash profile (20) and an inner sash profile (30) which can be snapped together with it, wherein the outer sash profile (20) has the outer glass stop (23) and the glass rebate surface (21) and the inner sash profile (30) has a first upper section (I) which forms the inner glass stop (33) and has a second section (II) below it which is integrally connected to the first section (I) and which completely covers the area of the outer sash profile (20) lying below the first section (I).The invention also relates to a sash frame made of such sash profiles (20, 30), a window (100) or a door with such a sash frame and a method for manufacturing a sash frame filled with a filling element.
