Split-Web Hinge Assembly for Precise Locking Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hinge designs for glass doors face challenges in precise assembly and adjustment of the locking mechanism due to the weight of the door causing misalignment during installation and adjustment, making it difficult to maintain the desired angular position.
Innovation Solution
The second hinge section is divided transversely to the pivot axis into two web parts, which are detachably connected using screws and positive-locking guides, allowing easy assembly and adjustment without loosening the connection during the process, and anti-rotation elements secure the locking element in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the clamping jaws are divided parallel to the pivot axis to lock the locking element, then the locking element can be secured in position, but the assembly and adjustment process becomes complex and difficult due to the door weight causing misalignment
Solution Approach 1:
The second hinge part is divided into two web parts (first web part and second web part) that can be detachably connected. This segmentation allows the locking element to be mounted on one web part while the other web part is attached, simplifying the assembly process. The dividing plane is oriented transversely to the pivot axis, which prevents the locking mechanism from being subjected to misaligning forces during assembly, thereby maintaining coaxial positioning without requiring complex adjustment procedures.
2Adaptability or versatility
If the clamping jaws are adjusted by loosening screws to allow locking element movement, then adjustment is possible, but the connection becomes loose and precise positioning is difficult to achieve
Solution Approach 1:
By dividing the second hinge part into detachably connectable web parts, the locking element can be precisely positioned during assembly before the final connection is made. The modular design allows for precise alignment to be achieved and maintained, as the web parts can be connected after the locking element is in its correct position, eliminating the need to loosen and retighten screws during adjustment.
3Ease of manufacture
If the hinge is assembled with the door attached, then installation is complete, but the door weight causes large perpendicular forces making precise adjustment difficult
Solution Approach 1:
The detachable connection between the web parts allows the locking mechanism to be assembled and adjusted in a controlled manner. The web parts can be connected after the locking element is positioned, enabling precise adjustment to be performed without the full weight of the door creating misaligning forces. This segmentation separates the assembly process from the final installed state, allowing precision work to be done under favorable conditions.

AI summary
The hinge (10) according to the invention, which can be used for glass or furniture doors or the like, has two hinge parts (11, 12) pivotally connected to each other about a pivot axis and a locking device (17) which essentially consists of a locking element (18) associated with the first hinge part (11) and movably guided against the action of a spring element (21), and a locking element (26) associated with the second hinge part (12) with a locking recess (29) that interacts with the locking element in a locking position. The locking element is arranged coaxially to the pivot axis between two hinge webs (32, 33) formed on the second hinge part and can be locked in various angular positions of its locking recess.To facilitate the assembly of the locking device and, in particular, its locking element, the invention proposes that the second band part (12) be at least partially divided/divisible transversely to the pivot axis (13) and comprise a first band part (31) having one of the two band webs (32) and a second band part (33) having the other of the two band webs (34), wherein the two band parts (31, 33) are detachably connectable/connected to each other by means of at least one connecting element (36).
