Integrated Vertical Horizontal Fall Protection Rope System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fixed horizontal systems for fall protection from building roofs do not address the lack of continuity in securing individuals when entering or exiting the roof via ladders or hatches, leading to increased accident risks, particularly in hazardous weather conditions.
Innovation Solution
A fixed system integrating vertical and horizontal securement elements, using steel ropes with connection assemblies and self-gripping devices, ensuring continuous protection by connecting the vertical ladder system to the horizontal roof system at the edge, allowing seamless transition and operation without complicated user actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate vertical and horizontal securement systems are used, then each system can be optimized for its specific function, but continuity of protection is lost when transitioning between them
Solution Approach 1:
The patent combines the vertical securement system (ladder anchorage) and horizontal securement system (roof edge protection) into a single integrated fixed system. The steel rope continuously connects from the ladder at the wall up to the roof edge and along the roof surface, eliminating the gap between separate systems and ensuring uninterrupted protection during transition.
2Reliability
If additional anchoring intermediate posts are installed to bridge the gap, then continuity of protection is improved, but user operation becomes more complicated
Solution Approach 1:
The patent removes the need for intermediate anchoring posts by directly integrating the vertical and horizontal securement functions into a continuous steel rope system. The rope extends seamlessly from the ladder anchorage point, over the roof edge, to the horizontal positioning points, eliminating intermediate components and simplifying user operation to merely attaching the safety harness to the continuous rope.
3Reliability
If fixed horizontal systems are positioned far from the roof edge, then assembly safety is improved for installers, but protection coverage is reduced for users
Solution Approach 1:
The patent positions the horizontal securement rope in three-dimensional space by routing it over the roof edge itself, utilizing the vertical dimension to achieve both goals. The rope is anchored at the edge and extends horizontally along the roof surface, allowing installers to work safely from a distance while users positioned at the edge are fully protected within the hazardous zone.

AI summary
The object of the invention is a fixed system for protection against falls from height, comprising a steel rope of a horizontal system positioned substantially parallel to the roof surface characterised in that it comprises a steel rope of a vertical system, whose upper segment is fixedly connected to one of the posts of the horizontal system, the steel rope of the horizontal system being fixedly situated above the roof level by means of at least two posts of the horizontal system.
