Upward Pin Guide Rail for Shading Device Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building opening shading devices face challenges in assembly, manufacturing cost, and space-saving packaging due to protruding insertion pins and complex assembly processes of traditional side guide rails, particularly in tight installation spaces.
Innovation Solution
A side guide rail design featuring a fastening pin protruding upwards from the upper end face, which is pressed into a pin insertion area on the guide rail before transport, allowing easy attachment of side parts with open pin inserts, facilitating assembly and reducing transport complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If insertion pins protrude downwards from side parts to connect to guide rails, then the winding shaft box can be positioned and fixed correctly, but assembly becomes difficult in cramped installation spaces and transport space efficiency decreases
Solution Approach 1:
The patent inverts the traditional connection approach by making the fastening pin protrude upwards from the guide rail instead of downwards from the side part. This inversion allows the side part to be simply placed on top of the guide rail, with the pin automatically engaging into the pin insert, greatly simplifying assembly in cramped spaces while maintaining reliable positioning
2Strength
If side guide rails are manufactured as one-piece profiles with fastening projections, then connection strength is improved, but manufacturing cost increases due to non-profile element production
Solution Approach 1:
The patent segments the side guide rail into two functional parts: a profile element (the rail itself) and a separate fastening pin. This segmentation allows the profile element to be manufactured using standard profile production methods, reducing cost, while the fastening pin can be a simple, inexpensive component that provides the necessary connection strength when assembled
3Ease of operation
If fastening pins are attached to side parts before transport, then assembly is simplified on site, but transport packaging efficiency decreases due to protruding pins
Solution Approach 1:
The patent inverts who carries the fastening element: instead of attaching pins to the side parts before transport, the fastening pins are attached to the guide rails. This allows side parts to be packaged compactly without protruding pins, while still enabling simple on-site assembly by placing the side part onto the pin-equipped guide rail

AI summary
The invention relates to a side guide rail (102; 202) for a building opening shading device with a curtain, such as a vertical awning, which is mounted on a winding shaft rotatably supported on two side parts (108; 208) in front of a building opening. The side guide rail (102; 202) is suitable for attachment to the building, e.g., to a window frame and/or to a wall reveal of the building opening, and for supporting one of the side parts (108; 208) on its upper end face. It has a longitudinally open guide groove (13) for the lateral guidance of the curtain and/or a drop bar attached to the underside of the curtain.The invention is characterized in that the side guide rail (102; 202) is rigidly connected to a mounting pin (6) projecting upwards from the upper end face of the guide rail (102; 202), which serves to attach the side part (108; 208), wherein the side guide rail (102; 202) has a profile section (15, 16; 115, 116) on which the guide groove (13) is formed, and a pin insertion area (14) open at the end face in which the mounting pin (6) is pressed in, so that the mounting pin (6) is fixed in place on the side guide rail (102; 202) even during transport and assembly. The invention further relates to a building opening shading device with such side guide rails (102; 202).
