Offset Guide Rail Profile for Easier Fall-Protection Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing profile arrangements for windows and doors with functional parts like fall protection are difficult to install due to the geometry of L- or U-shaped rails, which require a fixed projection beyond the frame plane, making attachment of the other leg to the inner surface of the projection challenging.
Innovation Solution
The profile arrangement is designed with a fastening section offset from the profile section, extending in the opposite direction, allowing for attachment outside the functional part's area, with a parallel fastening plane to the frame, and utilizing multiple profile parts for simplified assembly and stability, including snap-fit and screw connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an L- or U-shaped rail with a fixed projection is used to prevent movement of the functional part away from the frame, then the functional part is securely held, but the installation becomes difficult due to the geometry requiring attachment to the inner surface of the projection
Solution Approach 1:
The profile part is divided into two distinct sections: a profile section that prevents movement away from the frame, and a fastening section offset towards the frame that extends in the opposite direction for attachment. This segmentation allows each section to perform its specific function independently, simplifying installation while maintaining holding stability.
Solution Approach 2:
The fastening section is positioned in a different spatial location (offset towards the frame) than the profile section, creating a separate attachment plane that is more accessible for installation. This dimensional repositioning moves the fastening operation to a more convenient location while the profile section maintains its protective function.
2Reliability
If the profile section extends in an overlap to a partial area of the functional part to prevent movement away from the frame, then the functional part is securely held, but the available area for fastening is reduced
Solution Approach 1:
The fastening function is extracted from the profile section area and relocated to a separate fastening section that is offset towards the frame. This allows the profile section to fully extend over the functional part for movement prevention without compromising fastening area, as the attachment is performed in the offset fastening section.
Solution Approach 2:
The profile part is segmented into a profile section for movement prevention and a separate fastening section for attachment. This segmentation enables the profile section to maximize its overlap with the functional part while the fastening section provides dedicated attachment area offset towards the frame.

AI summary
The invention relates to a window or door (7) with a window or door opening in front of which a functional part (F) having a longitudinal extension (L), such as a pane part (5) serving as fall protection, is held on a frame (6) of the window or door (7) by means of a profile part (14) having a profile section (4), wherein the holding by the profile part (14) serves only to prevent movement of the functional part (F) away from the frame (6), but the possible movement towards the frame (6) is directly prevented by the frame (6), for this purpose the profile section (4) extends in an overlap (u) to a partial area of the functional part (F) in the installed state.For an advantageous design of the window or door, it is proposed that the profile part (14) is attached to the frame (6) via a fastening section (60) which is offset relative to the profile section (4) towards the frame (6) and extends in the opposite but same direction to the profile section (4). The invention further relates to a profile arrangement (1) with a first profile part (14) having a profile section (4) for holding a functional part (F) having a longitudinal extension (L), such as a glazing element (5) serving as fall protection, and to a profile arrangement (1) attached to a frame (6) of a window or door (7).
