Hinged Closure With Segmented Pipe Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hinge locks for sandwich-construction doors require significant pressure for installation, leading to door deformation, compromising the seal and insulation quality, and lack the ability to be operated from both sides, especially in emergency situations.
Innovation Solution
A hinge lock design with spreadable pipe sections and an inner handle mechanism that allows operation from both sides, preventing door deformation during installation and ensuring reliable sealing, while enabling emergency opening from the inside.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hinge locks are attached to sandwich-construction doors with significant pressure to ensure reliable connection, then the connection reliability is improved, but the door surfaces become deformed and the seal is compromised
Solution Approach 1:
The mounting plate is divided into multiple pipe sections (first pipe section, second pipe section, etc.) that can be independently adjusted. Each pipe section can be spread apart to distribute the mounting pressure, preventing concentration of force on a single point that would cause door surface deformation while still achieving reliable connection.
Solution Approach 2:
The pipe sections are designed with adjustable spacing that can be dynamically modified during installation. The spreadable structure allows the mounting plate to adapt to the door surface, distributing pressure evenly across multiple points rather than applying significant pressure at fixed positions, thus preventing deformation while ensuring reliable connection.
2Reliability
If hinge locks are attached with significant pressure to ensure reliable connection, then the connection reliability is improved, but the insulating material is damaged and insulation quality is impaired
Solution Approach 1:
The mounting plate is segmented into multiple pipe sections that distribute the mounting load across several locations rather than concentrating force. This prevents damage to the insulating material between door panels while still achieving reliable connection through the distributed pressure points.
Solution Approach 2:
The adjustable spacing of the pipe sections allows the mounting structure to adapt to the sandwich-construction door geometry, applying minimal necessary pressure at multiple points rather than significant pressure at fixed positions, thus protecting the insulating material from damage.
3Reliability
If traditional hinge locks are used on sandwich doors, then the door can be locked securely, but the door cannot be opened from the inside in emergency situations
Solution Approach 1:
The hinge lock system incorporates multiple handles (first handle on the outside, second handle on the inside) that can both operate the same locking mechanism. This multi-functionality allows the door to be securely locked from either side while enabling emergency operation from the inside by pulling the second handle, which triggers the unlocking mechanism without compromising security during normal operation.

AI summary
The invention relates to a hinge closure comprising a first hinge part (1) for attachment to the outside of a door and a second hinge part (2) for attachment to the outside of a door frame, wherein the first hinge part (1) has an actuating device by means of which the first (1) and the second hinge part (2) can be locked and unlocked together. The actuating device interacts with a shaft (16) that is suitable for passing through the door. An internal handle (23) is arranged at the end of the shaft (16) opposite the actuating device, by means of which the first (1) and the second hinge part (2) can be locked and unlocked together. The shaft (16) is surrounded by at least one tubular section (18, 18').
