Gate Door Leaf Lower Closing Element Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door designs face challenges in maintaining stability during opening and closing movements while ensuring user-friendliness and compatibility with various door leaf designs and drive types, particularly in vertically movable doors with integrated doors.
Innovation Solution
A lower closing element that extends over the entire width of the door leaf, incorporating an insert element with higher strength than the closing element, which can be partially or fully embedded within the closing element, providing additional stability without protruding, and can be designed as a hollow profile or U-profile to reduce dimensions and create a barrier-free passage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a door element is integrated into a gate leaf, then user-friendliness is improved, but stability during opening and closing movements deteriorates
Solution Approach 1:
The gate structure is segmented into a gate leaf and a door element that can move independently. The door element is divided into multiple sections that pivot relative to each other, allowing independent movement from the gate leaf while maintaining overall structural integrity through separate pivot joints.
Solution Approach 2:
The door element is integrated into the gate leaf structure, combining two functional elements (gate and door) into a single unified system. This merging allows the door to be part of the gate assembly while maintaining separate movement capabilities through integrated pivot joints.
2Stability of the object's composition
If the bottom edge element is made wider to accommodate the door element, then structural stability is improved, but the dimensions increase which may obstruct passage
Solution Approach 1:
The insert element is nested within the bottom edge element, with the insert having a smaller cross-section than the outer bottom edge element. This nested configuration allows the stronger insert to be hidden inside the lighter bottom edge element, providing reinforcement without increasing external dimensions that could obstruct passage.
Solution Approach 2:
The bottom edge element combines two different materials with different properties: a lighter outer material for the bottom edge element and a stronger inner material for the insert element. This composite construction optimizes both weight and strength characteristics without increasing overall dimensions.

AI summary
The invention relates to a gate with a door element (14) integrated into a gate leaf, wherein the gate leaf and the door element (14) are constructed by individual gate elements (1) that are pivotally connected to one another and are guided in lateral rails so as to be repositionable. The lower gate element (1) is connected at ground level via an intermediate element (5) to a closing element (3) extending over the entire width of the gate leaf. The closing element (3) is additionally provided with an insert element (4) extending beyond the width of the door element (14), which is wholly or partially enclosed by the closing element (3). The insert element (4) is designed as a hollow profile or as a U-profile. Furthermore, the invention relates to a lower closing element (3) for a gate element (1) that is provided with an insert element (4) for increasing stability, at least in the area of the door element (14).
