Vertically Movable Door Segment Drive Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vertically movable gates with multiple segments face challenges in distributing dynamic and static forces efficiently, leading to increased installation space requirements and limitations in passage height or width due to the need for larger drive mechanisms and connecting means.
Innovation Solution
Connecting multiple door leaf segments to the drive means at multiple points distributes forces across several connection points, allowing for a compact and stable design with reduced dimensions of the drive and connecting components, using a finite drive means like a chain and integrating the drive into the hinge joints for space-saving and efficient power transmission.

1Volume of moving object
If multiple door leaf segments are connected to the drive means at multiple points, then forces are distributed across several connection points enabling compact design, but the device complexity increases due to additional connection points and integration requirements
Solution Approach 1:
The drive means is integrated into the hinge joints, merging the driving function with the connecting function. The chain drive is incorporated within the hinge structure, eliminating the need for separate drive mounting structures and reducing overall device complexity despite multiple connection points
Solution Approach 2:
The hinge joints serve dual functions: both connecting adjacent door leaf segments and serving as connection points for the drive means. This multi-functionality reduces the need for additional components and simplifies the overall structure while enabling force distribution across multiple points
2Strength
If larger drives and connecting means are used to handle heavy door leaves, then the door can support heavier loads, but the installation space increases requiring widening of door frames
Solution Approach 1:
The door leaf is divided into multiple segments, each connected to the drive means at multiple points. This segmentation allows the total load to be distributed across several connection points, reducing the force required at each individual connection point and enabling the use of more compact drive and connecting components
Solution Approach 2:
Instead of increasing the size of individual connecting means to handle heavy loads, the solution transitions to a multi-dimensional approach by distributing connections across multiple points along the door leaf height, effectively using the vertical dimension to reduce horizontal space requirements

AI summary
The invention relates to a vertically movable gate with a gate leaf (1) comprising several gate leaf segments (2), wherein two adjacent gate leaf segments (2) are articulated to each other via at least one hinge (3), and with a motor drive which transmits a force for raising and lowering the gate leaf (1) to the gate leaf (1) via at least one drive element (4), and connecting elements (5) for connecting the drive element (4) to the gate leaf (1). According to the invention, gates of the aforementioned type are improved in such a way that such a gate can be moved freely between an open and a closed position largely independent of the forces acting upon it, and yet has a compact, stable and reliable design, by having several gate leaf segments (2) each individually connected to the drive element (4).
