Continuous Elastic Connecting Element for Sectional Door Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sectional door bolt arrangements are complex to assemble and do not provide adequate burglary security, as they require individual rod sections and adjustments, leading to incomplete locking and increased installation effort.
Innovation Solution
A continuous, elastically bendable connecting element that spans the entire length between the actuating device and locking devices, embedded within a door leaf core, simplifies assembly and ensures secure locking by allowing two or more locking devices to be adjusted with a single actuating element, while avoiding the need for individual rod sections and accommodating dimensional changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If individual rod sections are used to connect locking devices, then the bolt arrangement can be assembled, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The patent merges multiple individual rod sections into a single continuous elastically bendable connecting element that spans the entire length between the actuating device and locking devices. This eliminates the need for separate rod sections and their associated connection points, significantly simplifying the assembly process while reducing structural complexity.
Solution Approach 2:
The connecting element is designed with continuous bending lines that allow it to adapt to the three-dimensional arrangement of locking devices at different positions. This segmentation through bending lines enables the single element to navigate around the door leaf structure and connect multiple locking devices without requiring mechanical joints or adjustments.
2Reliability
If multiple locking devices are used to improve burglary security, then security is enhanced, but the actuation mechanism becomes more complex
Solution Approach 1:
The patent combines multiple locking devices into a single actuation system using one continuous connecting element that transmits force from a single actuating device to all locking devices simultaneously. This ensures that all locking elements are actuated together, providing reliable burglary security while keeping the actuation mechanism simple and unified.
3Reliability
If rod sections are attached to individual door leaf elements, then locking functionality is achieved, but installation effort and adjustment requirements increase
Solution Approach 1:
The patent attaches the single continuous connecting element to multiple door leaf elements at different positions, eliminating the need for separate rod section installations. The element is continuously guided through grooves in the door leaf elements, ensuring reliable locking functionality while dramatically reducing installation effort and eliminating adjustment requirements.
4Reliability
If the connecting element is made rigid to maintain force transmission, then locking reliability improves, but adaptability to tilting axes is reduced
Solution Approach 1:
The patent employs a continuous elastically bendable connecting element that can flex and adapt to the tilting movements of door leaf elements while maintaining its structural integrity and force transmission capability. The element's elastic bendability allows it to conform to the dynamic geometry of the door assembly during operation.
Solution Approach 2:
The connecting element is designed with continuous bending lines that allow it to dynamically adapt its shape as the door leaf elements tilt during opening and closing operations. This dynamic adaptability ensures continuous force transmission to the locking devices regardless of the door's position or orientation.

Function Achieved in This Case
The solution simplifies the assembly process and enhances burglary security by ensuring reliable locking with reduced effort and improved stability, as the connecting element maintains force transmission and adapts to tilting axes without altering the door frame dimensions.

AI summary
The locking arrangement has a connecting device with a connecting element (20) extending continuously through the total length between an actuating device and a locking device. The connecting element bends, particularly elastically bends perpendicular to its longitudinal axis and parallel to the deflection line. The door leaf swivels relative to a swiveling axis running in a closing position of the gate leaf. Independent claims are included for the following: (1) a sectional door with a guide rail arrangement; and (2) a method for manufacturing a sectional door.
