Glass Door Hinge Orthogonal Roller Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hinge systems for glass swing doors lack precision in adjusting the locking position to accommodate construction tolerances, leading to imprecise door alignment and potential instability over time.
Innovation Solution
A hinge design featuring an adjustable roller mounted orthogonally to the hinge axis, rotatably on a piston within an actuating cylinder, allowing for precise radial adjustment to set the zero position accurately, ensuring the door remains securely closed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rotary body with latching points is used to correct the locked position, then the door leaf can be fixed in various positions, but the correction is imprecise and requires additional balls or rollers
Solution Approach 1:
The invention changes the adjustment parameter from discrete rotary body positions to continuous axial displacement of the roller piston. The roller can be adjusted continuously along the axial direction by displacing the roller piston, enabling precise positioning of the zero position rather than relying on discrete latching points.
Solution Approach 2:
The invention separates the adjustment function into two independent directions: axial displacement of the roller piston for precise zero position setting, and radial adjustment of the actuating cylinder for adapting to construction tolerances. This segmentation allows each direction to be optimized independently.
2Adaptability or versatility
If additional balls or rollers are used to brace between the bearing block and rotary body, then correction is possible, but the correction is very imprecise
Solution Approach 1:
The roller acts as an intermediary element between the cam and the actuating cylinder. By positioning the roller on the cam surface, it translates the axial displacement of the roller piston into precise angular adjustment of the door leaf, enabling accurate zero position setting without direct contact between adjustment mechanisms.
3Measurement precision
If the actuating cylinder is adjusted radially with play in the bore, then small and precise adjustment ranges are possible, but the structure becomes more complex
Solution Approach 1:
The invention merges the adjustment functions into a integrated mechanism where the roller piston's axial displacement and the actuating cylinder's radial adjustment work together through the cam-roller interaction. This combining achieves precise positioning without requiring separate complex adjustment systems for each direction.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables precise adjustment of the door's zero position to compensate for construction tolerances, maintaining the door's closed position reliably even after extended use by allowing small and precise adjustments through the actuating cylinder's radial play.
Implementation Method 1
a roller which is arranged to be adjustable orthogonally to the longitudinal axis of the hinge and is rotatably mounted in a roller piston on which a spring acts
Implementation Method 2
The roller piston in turn is arranged so that it can move axially in an actuating cylinder which is arranged in a bore of the bearing block with radial play
Implementation Method 3
on which a cam with at least one recess is arranged

AI summary
The invention relates to a joint hinge (1), particularly for glass swinging doors, having a stationary hinge part, a leaf hinge part (2) pivoting about the stationary hinge part, a pivoting axis engaging through the stationary hinge part and the leaf hinge part (2), a cam (7a) having at least one recess (7b) being disposed on said axis, and a roller (22) to which a force is applied and which interacts with the cam (7). In order to obtain an accurate adjustability of the neutral position of the door, the invention provides that the roller (22) is adjustably disposed orthogonal to the longitudinal axis of the joint hinge (X-X).
