Slide and Swing Sash System with Floor-Loaded Carriages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide-and-swing window panel systems face difficulties in installation on ceilings with limited carrying capacity, as they require significant structural support, making them unsuitable for suspended ceilings.
Innovation Solution
The system reconfigures the mounting of window panels, where at least two panels are mounted in the floor rail profile using carriages, allowing the ceiling rail profile to guide them without bearing the weight load, reducing tensile stress on the ceiling. This is achieved through the interaction of lifting runners and ramp elements, which relieve rollers of stress and enable window panels to be pivoted and guided without contact with the floor rail.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the ceiling rail profile is used to support and guide window panels, then the window panels can be guided and pivoted, but the ceiling requires great carrying capacity which limits installation options
Solution Approach 1:
The weight-bearing function is extracted from the ceiling rail profile and transferred to the floor rail profile. The ceiling rail profile retains only the guiding function, while the floor rail profile assumes the load-bearing responsibility through carriages that roll on its bottom surface.
Solution Approach 2:
Instead of the ceiling rail profile supporting the window panels from above, the floor rail profile supports them from below. This inversion allows the system to be installed on ceilings with limited carrying capacity while maintaining the same guiding and pivoting functionality.
2Reliability
If the ceiling rail profile bears the weight load of window panels, then the panels can be supported, but the tensile stress on the ceiling rail profile increases
Solution Approach 1:
The load-bearing function is extracted from the ceiling rail profile and transferred to the floor rail profile. The ceiling rail profile retains only the guiding function, while the floor rail profile assumes the load-bearing responsibility through carriages that roll on its bottom surface.
Solution Approach 2:
Carriages are introduced as intermediary elements between the window panels and the floor rail profile. These carriages roll on the bottom surface of the floor rail profile, providing stable support while eliminating direct tensile stress on the ceiling rail profile.
3Ease of operation
If window panels are mounted in the ceiling rail profile, then they can be guided, but the ceiling structure must have high carrying capacity
Solution Approach 1:
The system is segmented into two distinct functional components: the ceiling rail profile dedicated to guiding and the floor rail profile dedicated to load-bearing. This segmentation allows each component to be optimized for its specific function without compromising the other.
Solution Approach 2:
Guide cylinders are introduced as intermediary elements between the window panels and the ceiling rail profile. These cylinders engage with the ceiling rail profile for guidance while transferring all weight loads to the floor rail profile through the carriages, eliminating the need for high ceiling carrying capacity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration allows for the installation of slide-and-swing window panel systems on ceilings with limited carrying capacity by distributing the weight load to the floor rail profile, reducing the stress on the ceiling rail profile, enabling secure and efficient operation of the window panels.
Implementation Method 1
Because of the interaction of lifting runner and ramp element, the window panel with the lifting runner disposed on it is lifted as it passes the ramp element.
Implementation Method 2
the window panels are each mounted in the floor rail profile by way of at least one carriage

AI summary
A slide and swing leaf/sash system includes a floor rail profile and a ceiling rail profile which are each C-shaped and in which at least two leaves/sashes arranged therebetween are displaceably guided, which leaves/sashes are mounted at least in each case by at least one carriage in the floor rail profile in such a way that, in the swiveled-in state of the leaves/sashes, the weight load of the leaves/sashes is completely absorbed by the floor rail profile. At least one lateral outlet opening for releasing a leaf/sash is arranged in the floor rail profile, a lifting runner, which is arranged above the floor rail profile, being mounted on at least one leaf/sash, a ramp element being arranged on the floor rail adjacent to at least one outlet opening and interacting with the lifting runner in such a way that the leaf/sash is raised on passing the ramp element.
