Glass Door Corner Fitting with Adjustable Distancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional corner fittings for glass doors face issues with accommodating door elements of varying thicknesses, leading to gaps and reduced durability due to the need for increased intermediate layers, which alter the construction depth and clamping effect.
Innovation Solution
A corner fitting design featuring variably adjustable distancing elements between fitting elements, allowing the distance to the door element to remain constant regardless of thickness, achieved through threaded pins or rods that can be adjusted to match the door leaf thickness, maintaining a consistent intermediate layer and preventing gaps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the intermediate layer is increased to accommodate door elements of different thicknesses, then the adaptability to different door thicknesses is improved, but the construction depth increases and the clamping effect is reduced
Solution Approach 1:
The corner fitting employs adjustable fitting elements that can be positioned at different distances from the door element through a standardized adjustment mechanism (e.g., threaded rods, slots, or holes). This dynamic adjustability allows the same corner fitting to accommodate various door thicknesses without changing the intermediate layer thickness or construction depth, thereby resolving the contradiction between adaptability and maintaining constant construction depth.
2Adaptability or versatility
If the intermediate layer is increased to compensate for thickness differences, then the adaptability to different door thicknesses is improved, but the clamping effect and durability are reduced
Solution Approach 1:
The adjustable fitting elements enable dynamic positioning to maintain optimal clamping force regardless of door thickness variations. By adjusting the distance between the fitting element and the door element, the system preserves the intended clamping effect and durability while accommodating different door thicknesses, eliminating the need to increase the intermediate layer which would otherwise reduce the clamping effect.
3Adaptability or versatility
If the cover is exchanged to prevent gap creation, then the adaptability to different door thicknesses is improved, but the device complexity and costs increase
Solution Approach 1:
The corner fitting is designed with universal adjustability through standardized adjustment mechanisms (threaded rods, slots, holes) that allow a single cover and a single set of fitting elements to accommodate various door thicknesses. This eliminates the need for multiple covers or intermediate layers of different thicknesses, thereby reducing device complexity and costs while maintaining adaptability to different door thicknesses.

AI summary
A corner fitting for a door element, in particular for a glass door element, includes a first fitting element and a second fitting element, which each include, at least sectionwise, a locating portion. The locating portion includes an intermediate layer able to contact the door element. The fitting elements delimit the restraining area, wherein a holding element is in operative connection with a connecting element, which serves for supporting the door element on a center of rotation and/or an axis.At least one variably adjustable distancing element is disposed between the fitting elements outside the locating portions, wherein the distancing element forms a counter-bearing to the locating portions and the door element, which can be restrained in the restraining area.
