Cover Guide Hinge for Linear Opening Without Interior Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cover elements for openings in stationary structures require multiple movements and projections into the interior space, causing space constraints and hindering object arrangement.
Innovation Solution
A guide system with hinges and locking devices allows for a cover element to move linearly between closed and open positions, enabling parallel movement without tilting, and includes a locking mechanism for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cover element is moved from closed position to tilted position and then to parallel position before lateral displacement, then the cover element can be opened and laterally displaced, but the cover element always projects into the interior space causing space constraints and hindering object arrangement
Solution Approach 1:
Instead of moving the cover element into the interior space and then laterally displacing it, the invention inverts the sequence by first laterally displacing the cover element outward and then opening it. This is achieved through the guide system with hinge lever mechanisms that enable lateral movement before rotation, eliminating the projection problem throughout the opening process
2Manufacturing precision
If a hinge lever mechanism is used to move fitting portions linearly between end positions, then precise linear guidance is achieved, but the device complexity increases
Solution Approach 1:
The hinge mechanism is segmented into separate functional components: hinge bodies mounted on the stationary structure, hinge levers attached to the cover element, and guide elements. This segmentation allows each component to be optimized independently and simplifies manufacturing and assembly while maintaining precise linear guidance through the coordinated interaction of segmented parts
3Reliability
If locking devices are added to lock fitting portions in end positions, then burglary protection and defined closure are provided, but the device complexity increases
Solution Approach 1:
The locking function is merged with the hinge lever mechanism itself. The hinge levers are designed to automatically lock in the closed position through their mechanical configuration, and can be easily unlocked by reversing the opening motion. This integration eliminates the need for separate locking devices while maintaining burglary protection and defined closure

AI summary
A guide system for movably supporting a cover element for covering an opening in a stationary structure, the a cover element being movable by the guide system between a closed position, in which the a cover element covers the opening, and an open position, in which the cover element is spaced apart from the opening substantially orthogonally. The guide system includes a hinge including a first fitting portion to be arranged on the stationary structure, a second fitting portion configured to be arranged on the cover element, and a hinge lever mechanism configured to move the two fitting portions substantially linearly between a first end position, corresponding to a closed position of the cover element, and a second end position, corresponding to an open position of the cover element. A locking device is configured to lock the fitting portions in the first end position and/or in the second end position.
