Scaffolding Fastening Element With Projection For Railing Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scaffolding systems face challenges in easily mounting or removing railings from scaffolding poles without risking accidental disassembly, often requiring complex moving parts or orientations that complicate handling and increase the risk of snagging.
Innovation Solution
A scaffolding element with a rigidly connected fastening element having a free end that runs parallel to the scaffolding pole, combined with a railing design featuring symmetrical through-openings, allows for simplified mounting and dismounting by rotating the railing 90°, while a projection prevents unintended removal, maintaining a large clearance width and security against accidental disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a gate or pivotable plate is used to secure the railing on a pin, then the railing can be attached to the scaffolding pole, but the unthreading of the railing becomes more difficult and requires complex moving parts
Solution Approach 1:
Instead of using a gate or pivotable plate that requires complex moving parts for attachment, the invention inverts the approach by using a simple through-opening that allows the railing to be inserted and secured by a straightforward rotational movement of the fastening element body, eliminating the need for complex gate mechanisms while maintaining secure attachment
Solution Approach 2:
The fastening element is divided into distinct functional parts: a through-opening for the railing, a fastening element body that rotates, and a projection that prevents unintended removal. This segmentation allows each component to perform its specific function independently, simplifying the overall mounting and dismounting process while ensuring reliability
2Reliability
If a pin with gate guide or bend is used to secure the railing, then the railing can be locked to the scaffolding pole, but the handling becomes more complex and the clearance width is reduced
Solution Approach 1:
The invention extracts the complex gate guide and bend mechanisms from the fastening system, replacing them with a simple through-opening and rotational fastening body. This removal of unnecessary complex components simplifies handling while maintaining the locking function through the projection that prevents unintended removal
Solution Approach 2:
Instead of using a complex pin with gate guide or bend to achieve locking, the invention inverts the approach by using a simple rotational fastening body with a through-opening, where the locking action is achieved through the projection preventing unintended removal, thereby reducing handling complexity
3Reliability
If a projection is added to prevent unwanted dismantling, then security against accidental disassembly is improved, but the clearance width may be reduced
Solution Approach 1:
The projection is positioned locally at the end of the fastening element body where it is most effective for preventing unintended removal. This localized placement provides the necessary security against accidental disassembly while minimizing the impact on the overall clearance width, as the projection only extends in the direction parallel to the scaffolding pole axis

AI summary
A scaffolding element having a scaffolding pole, at least one fastening element being disposed or formed on the scaffolding pole. The fastening element preferably has a fastening element body. The fastening element body can be L-shaped. Preferably, the free end of the fastening element body points straight upwards when the scaffolding element is in the mounted state. A projection is disposed or formed below the free end on the fastening element body, in particular in a section parallel to the longitudinal axis of the scaffolding pole. The projection can be part of a U-shaped bead.
