Sliding Window Fitting Arrangement Transverse Slide Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding door and window locking mechanisms allow for insufficient protection against break-ins due to play in the assembly, which can cause the striker to disengage when subjected to force in the horizontal direction, failing to securely lock the sash against the seal.
Innovation Solution
A fitting arrangement with an actuating mechanism and control elements that include a latch element and a transverse slide, allowing the latch to engage in a receptacle perpendicularly to the main plane, preventing movement of the sliding sash relative to the fixed frame or sash, and utilizing a second transverse slide with a striker to pull the sash into place, ensuring secure locking in both vertical and horizontal directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a striker is used to lock the sash against the seal, then the sash can be securely locked in the vertical direction, but the striker can slide out horizontally when subjected to force during break-in attempts
Solution Approach 1:
The locking function is divided into two independent components: a striker for vertical locking and a latch element for horizontal positioning. The latch element is integrated into a transverse slide mechanism that operates independently from the striker, allowing each component to specialize in preventing displacement in its respective direction without interfering with the other.
Solution Approach 2:
The latch element extends in the horizontal dimension perpendicular to the striker's vertical action. By adding this horizontal locking dimension through the transverse slide mechanism, the system prevents horizontal displacement that the vertical striker alone cannot prevent, creating a two-dimensional locking solution.
2Adaptability or versatility
If play is built in to compensate for assembly tolerances, then the locking mechanism can accommodate manufacturing variations, but the striker can disengage when force is applied in the slide opening direction
Solution Approach 1:
The tolerance compensation function is assigned specifically to the latch element and transverse slide mechanism, while the striker maintains its primary vertical locking function. The latch element's horizontal positioning capability handles assembly variations without compromising the striker's break-in resistance, allowing each component to optimize its specific function.
3Strength
If a locking arrangement with striker and closing piece is used, then the sash can be pressed against the seal, but the arrangement does not prevent horizontal movement of the sash
Solution Approach 1:
The sealing function is dedicated to the striker-closing piece interaction in the vertical direction, while the latch element-transverse slide mechanism handles horizontal position stability. This functional segmentation allows the sealing mechanism to optimize pressing force without being compromised by horizontal movement concerns.

AI summary
A fitting arrangement for a sliding window or a sliding door has an actuating mechanism that can be arranged on a sliding sash and that is movable at least with a portion in the rebate circumferential direction, and a first control element that is arranged on the portion of the actuating mechanism, and a second control element that is arranged on a transverse slide. The transverse slide has a locking element, and the control elements interact and are tailored to one another in such a way that, upon a movement of the portion in the locking direction, the locking element is moved away from the sliding sash perpendicularly to a main plane of the sliding window or of the sliding door.
