Bedspring Lifting Mechanism Using a Telescopic Gas Spring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanisms for lifting bedsprings require expensive and complex anti-friction sleeves, contribute significantly to weight, cost, and size, and are prone to accidental closure due to exposed hooks, which hinder smooth operation and assembly.
Innovation Solution
A simplified mechanism using two parallel lifting arms with a gas spring and integrated locking elements within the gas spring structure, allowing stable lifting and tilting of bedsprings without the need for external sleeves, and incorporating a locking mechanism to maintain the bedspring's horizontal position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If anti-friction sleeves are used to ensure smooth sliding of the gas spring, then the sliding smoothness is improved, but the cost, assembly time, weight, and complexity increase
Solution Approach 1:
The patent removes the anti-friction sleeves from the gas spring mechanism entirely. Instead of adding specialized components to reduce friction, the invention uses the inherent low-friction properties of the gas spring's internal design, thereby eliminating the need for separate anti-friction elements and simplifying the overall mechanism.
Solution Approach 2:
The gas spring is designed to provide its own low-friction operation through its internal structure without requiring external anti-friction components. The mechanism serves itself by utilizing the self-lubricating properties of the gas spring's piston and cylinder arrangement, eliminating the need for additional maintenance or specialized parts.
2Ease of operation
If anti-friction sleeves are installed in the gas spring, then the sliding performance is improved, but the assembly time and cost increase
Solution Approach 1:
The patent eliminates the anti-friction sleeves from the assembly, removing the time-consuming step of installing these specialized components. The gas spring operates without requiring these additional parts, thereby reducing assembly time and simplifying the manufacturing process.
3Ease of operation
If the hook is made accessible for easy operation, then the ease of use is improved, but the risk of accidental closure increases
Solution Approach 1:
The patent removes the traditional hook mechanism entirely and replaces it with a push-button release system. This new mechanism maintains ease of operation through simple button activation while inherently preventing accidental closure by requiring deliberate user action rather than allowing unintended hook engagement or disengagement.
Solution Approach 2:
The invention replaces the mechanical hook system with a different mechanical approach - a push-button release mechanism. This substitution maintains user accessibility while improving reliability by eliminating the accidental engagement risks associated with exposed hooks, as the button system requires intentional activation.
4Ease of operation
If the mechanism uses traditional lifting arms with sleeves, then the lifting function is achieved, but the weight and size increase
Solution Approach 1:
The patent removes the heavy anti-friction sleeves from the lifting mechanism, significantly reducing the overall weight. The gas spring operates without these additional components, allowing the mechanism to achieve the required lifting function with minimal weight while maintaining operational effectiveness.

AI summary
A mechanism for lifting a bedspring (12) with respect to a frame or containment furniture (10) lying on the ground is liked to be simplified. The mechanism comprises a first (20) and a second (30) lifting arm, one of the two arms being extendable telescopically and both mounted substantially parallel to each other and hinged to the frame and to the bedspring to form an articulated parallelogram, in order to lift the bedspring between two positions, keeping it always substantially horizontal. SOLUTION: the extendable arm consists only of a gas spring.
