Lowerable Sliding Door Seal With Decoupled Force Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seals for sliding gates or doors with multiple segments face challenges in ensuring uniform sealing due to tolerances and play in components, requiring precise assembly and adjustment, which is time-consuming and complex.
Innovation Solution
The solution involves arranging movement deflection means into two groups, with a trigger-side group connected directly or via a coupling rod to the coupling element, allowing force decoupling to transmit the trigger force effectively to the sealing strip, enabling easier assembly and adjustment without considering the alignment of movement deflection means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If motion deflection means are directly attached to release rods, then force transmission is achieved, but assembly complexity increases and tolerances accumulate
Solution Approach 1:
The coupling element serves as an intermediary component between the release rod and the motion deflection means. Instead of directly attaching the motion deflection means to the release rod, the coupling element mediates the connection, allowing for independent positioning and adjustment of each component while maintaining effective force transmission to all sealing strips.
2Manufacturing precision
If threaded connection is used to compensate tolerances, then force transmission improves, but adjustment time increases
Solution Approach 1:
The coupling element is divided into separate functional segments: a connection portion that attaches to the release rod and a coupling portion that connects to the motion deflection means. This segmentation allows each part to be independently manufactured and adjusted, reducing the need for time-consuming threaded adjustments while maintaining precision in force transmission.
3Force
If motion deflection means are positioned relative to release rods, then force transmission is enabled, but tolerance accumulation occurs
Solution Approach 1:
The coupling element acts as a mediator that decouples the positioning requirements between the release rod and the motion deflection means. It provides a reference structure that allows the motion deflection means to be positioned relative to the coupling element rather than directly to the release rod, preventing tolerance accumulation while maintaining effective force transmission.

AI summary
The invention relates to a lowerable seal for sliding gates, comprising at least two segments (1), at least two release rods (2), and a release mechanism (3), wherein each segment (1) has: - a coupling element (17) for coupling on both sides with one of the release rods, - a downwardly open housing (11), - a sealing strip (12), and - a lowering mechanism, wherein the release mechanism (3), the release rod (2), and the coupling elements (17) are connected to one another, wherein the lowering mechanism slidably connects the housing (11) and the sealing strip (12) to one another, and the lowering mechanism comprises movement deflection means (Ma, Mb, Mc) to convert a movement of the coupling elements (17) into a downward movement of the sealing strip, wherein the coupling element (17) of each segment has a projecting part (171) which has a connecting structure that connects the coupling element to the lowering mechanism of the segment (1).so that each coupling element (17) forms a force coupling element by means of which a force introduced into the seal via the trigger (3) can be transmitted in order to be coupled into the motion deflection means (Ma, Mb, Mc) of the lowering mechanism of each segment (1) in order to move the sealing strip (12) downwards.
