Roller Hinge Lateral Adjustment via Axle-Mounted Seat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional roller hinges require adjusters to be placed in the mounting flanges, making adjustments only possible when the panel is open and increasing manufacturing costs, while also limiting their use in situations with low surrounding door or window frames due to visibility and space constraints.
Innovation Solution
The design incorporates a mounting projection and cavity within the axle, allowing lateral adjustment of the hinge tab, with a fastener securing the tab in place, enabling the panel to be inserted laterally and adjusted without axial misalignment, and providing adjusters for all three spatial directions within the 'roller' of the hinge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If adjusters are placed in the mounting flanges of conventional roller hinges, then lateral adjustment of the panel is enabled, but adjustments can only be performed when the panel is open and the mounting flanges require additional space that increases manufacturing costs
Solution Approach 1:
The patent combines the adjuster mechanism with the hinge tab structure itself, rather than placing separate adjusters in the mounting flange. The hinge tab incorporates an adjustable seat with a fastener that secures the tab to the axle, integrating the adjustment function directly into the hinge tab. This merging eliminates the need for separate mounting flange adjusters, making adjustments accessible when the panel is closed while simplifying the mounting flange design.
2Adaptability or versatility
If adjusters are placed in the mounting flanges, then lateral adjustment is possible, but this requires more space and cavities inside the door rebate leading to higher manufacturing costs
Solution Approach 1:
The adjustment mechanism is merged into the hinge tab and axle assembly. The hinge tab includes a seat that can laterally adjust its position on the axle using a fastener. This integration means the adjustment mechanism does not require additional cavities or space in the door rebate, as the adjustment components are contained within the hinge tab structure itself, which is already part of the hinge assembly.
3Ease of manufacture
If the axis pin is threaded from above by lifting the panel, then the bearing can be assembled, but this prevents use in situations with low height to the surrounding door or window frame
Solution Approach 1:
The patent inverts the traditional assembly sequence. Instead of threading the axis pin from above by lifting the panel, the hinge tab with its seat is first attached to the axle laterally, and then the entire assembly is installed. The hinge tab can be laterally adjusted and secured to the axle before final installation, allowing the panel to be installed from below or in low-clearance situations without requiring vertical lifting space.
4Device complexity
If all adjusters are kept within the hinge roller, then visual appearance is maintained and manufacturing costs are reduced, but the hinge must accommodate multiple adjustment functions in a compact space
Solution Approach 1:
The patent employs a nested structure where the adjustable seat is integrated within the hinge tab, which itself is attached to the axle. The fastener is mounted in the axle and secures the hinge tab within the seat. This nested arrangement allows multiple adjustment functions (lateral position of the seat on the axle, and potentially other adjustments within the hinge tab) to be contained within the compact hinge roller structure without requiring separate external adjusters, maintaining visual appearance while providing versatility.

AI summary
The invention relates to a hinge for a door or a window, in particular designed as a roller hinge, comprising a frame hinge part with a mounting flange and a substantially cylindrical bearing, a panel hinge part (1) with a mounting flange (2) and a hinge tab (3) as well as an axle (4) pivotably connecting the two hinge parts one above the other in the vertical direction in the mounted state, with an axis pin (5) insertable into the bearing and a section with a seat (6) for the hinge tab (3) and the latter is adjustable transversely to the longitudinal axis of the axle (4) via an adjuster (7) within the seat (6). A mounting projection (8) is in the seat (6). A mounting cavity (9) is provided on the hinge tab (3) formed on the lower end face (10) of the hinge tab (3) or as an undercut cavity on the end face (11) of the hinge tab (3) facing away from the mounting flange (2) of the panel hinge part (1). In the assembled state, the mounting projection (8) comes to rest in the mounting cavity (9). A fastener (12) is provided in the axle (4) that secures the hinge tab (3) within the seat (6) in the assembled state.
