Swing Lever Link Extends Pendulum Length
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional swings experience high loads leading to increased wear and reduced safety, limiting operational reliability and swinging pleasure.
Innovation Solution
A swing arrangement with a support device that uses levers or links coupled to the support device via pivot bearings, allowing passive deflection of the swing seat, which extends the pendulum length and reduces wear by guiding the suspension means along a non-circular path, using elastic chains or ropes for stable suspension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the suspension means is arranged directly on the fixed support structure, then the structure is simple, but the swing frame is exposed to high loads leading to increased wear and reduced safety
Solution Approach 1:
The patent introduces a lever or link as an intermediary component between the fixed support structure and the suspension means. This mediator transfers and distributes the loads, preventing direct high-load concentration on the support structure, thereby reducing wear while maintaining structural simplicity and enhancing safety.
2Ease of operation
If the pendulum length is extended to increase swinging pleasure, then the swinging experience is improved, but the swing frame is exposed to higher loads and wear
Solution Approach 1:
The lever or link acts as a mechanical intermediary that enables pendulum length extension for enhanced swinging pleasure while distributing the resulting increased loads across multiple components rather than concentrating them on the swing frame, thereby maintaining operational reliability.
Solution Approach 2:
The lever or link is designed to move dynamically during swinging, adjusting its position and orientation to optimize the pendulum length throughout the swing arc. This dynamic adjustment allows extended swinging pleasure while distributing loads more evenly, reducing peak stresses on the frame.
3Reliability
If the suspension means is coupled passively via lever or link, then wear is reduced and safety improved, but the device complexity increases
Solution Approach 1:
The lever or link serves as a passive intermediary component that enhances safety by reducing wear on the support structure. While it does add a component to the system, the design keeps this intermediary simple in construction and easy to install, minimizing the actual increase in device complexity while achieving the safety benefit.

AI summary
The swing arrangement (1, 1', 1", 1''') has a support device (20, 21, 22), in particular a stationary one, on which a swing seat (10) is suspended with at least one suspension element (11, 12) that is subject to at least tensile stress. The suspension element (11, 12) is coupled to the support device (20, 20a, 21, 21a, 22), in particular passively, via at least one lever or link (23, 24).
