Sliding Window Fitting with Transverse Displacement Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing displacement arrangements for sliding doors and windows face difficulties in sealing and opening due to the obstruction caused by seals between the sliding leaf and the fixed surround, leading to increased forces on the carriage that may result in damage or tilting of rollers.
Innovation Solution
A displacement arrangement featuring a rotatable roller on a guiding member that moves perpendicularly to the rebate, allowing the leaf to be displaced transversely relative to the fixed surround with reduced forces and minimized wear, using a control contour and projection mechanism that engages with a drive rod, and a dovetail-like transverse guide to ensure stability and prevent tilting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a seal is arranged between the fixed surround and the sliding leaf, then sealing performance is improved, but the leaf cannot be displaced transversely relative to the main plane, making opening difficult
Solution Approach 1:
The displacement arrangement enables dynamic transverse displacement of the sliding leaf relative to the fixed surround through the interaction between the control projection on the drive rod and the control contour on the guiding member. This dynamic movement capability allows the leaf to move away from the seal during opening and return to sealing position during closing, resolving the contradiction between maintaining seal contact and enabling smooth operation
2Reliability
If forces are applied to press the leaf against the seal using a carriage and bolt mechanism, then sealing contact is improved, but not inconsiderable forces acting on the carriage may lead to damage or tilting of the rollers
Solution Approach 1:
The guiding member acts as an intermediary between the drive rod and the sliding leaf. It features a roller that contacts the fixed surround to guide transverse movement, while a second roller contacts the sliding leaf to transmit pressing forces. This intermediary structure distributes forces more effectively, preventing direct transmission of high forces to the carriage rollers and thereby improving their durability
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 solution allows for easy and unimpeded opening and closing of sliding doors and windows by distributing forces through a roller system, reducing wear and preventing tilting, while maintaining a secure seal between the leaf and the fixed surround.
Implementation Method 1
the guiding member has a roller which can be rotated about a rotation axis orientated perpendicularly to the circumferential direction of the rebate and parallel with the main plane of the window or the door and which is supported on a surround portion when the displacement arrangement is mounted

AI summary
A displacement arrangement for displacing a sliding leaf of a window or a door relative to a fixed surround of the window or the door in a direction which is transverse relative to a main plane of the window or the door includes an actuation mechanism arranged on the leaf that is movable with at least one portion in a circumferential direction of a rebate, a first control element arranged on the portion of the actuation mechanism and a second control element arranged on a guiding member, where the guiding member is guided on a fixed surround and arranged on the leaf to be movable transversely relative to the circumferential direction of the rebate.
