Wall Hanger Connecting Rod Spring Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing musical instrument mounts, such as wall hangers and floor stands, often feature complex mechanical constructions that are prone to malfunction due to contamination and mechanical complexity, leading to operability issues.
Innovation Solution
A simplified mount design where a connecting rod couples the lower cradle directly to the holding arms, using a single pivot and a spring to achieve a compact and mechanically simple construction, eliminating the need for guides, levers, and Bowden cables, with adjustable components to accommodate different instrument sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex mechanical constructions with guides, levers, and Bowden cables are used, then the mounting can achieve holding functionality, but the operability deteriorates due to contamination and mechanical complexity
Solution Approach 1:
The patent removes complex intermediate components (guides, levers, Bowden cables) from the mechanical system, retaining only the essential spring element to directly couple the lower cradle and holding arms, thereby eliminating contamination points and simplifying the mechanical construction
Solution Approach 2:
Instead of using multiple intermediate components to transmit force, the patent inverts the approach by using a single spring element that directly provides the necessary mechanical coupling and force transmission between the lower cradle and holding arms
2Ease of operation
If multiple intermediate components are used to transmit movement, then the holding arms can be actuated, but the risk of malfunction increases due to contamination
Solution Approach 1:
The patent extracts and removes all intermediate force transmission components (guides, levers, Bowden cables) that are susceptible to contamination, leaving only the spring element and direct mechanical coupling to actuate the holding arms, thereby eliminating malfunction risks associated with contaminated components
3Device complexity
If a simplified design with direct coupling is used, then the mechanical construction is simplified, but the adaptability to different instrument sizes must be maintained
Solution Approach 1:
The patent incorporates adjustable elements that allow the mounting to dynamically adapt to different instrument sizes while maintaining the simplified mechanical construction with direct coupling, enabling versatility without adding complexity

Implementation Method 1
at least one spring being prestressed to urge the lower cradle into a rest position and the two holding arms into an open position
Implementation Method 2
the spring being compressed as the lower cradle moves from its rest position into the working position

AI summary
The invention relates to a bracket and, in particular, a wall bracket for a musical instrument (1), particularly for a stringed instrument. To this end, the bracket has an adjustable base (4) for receiving an instrument body (1a) and at least two retaining arms (5), which are able to pivot relative to an anchor element (3), for detachably securing an instrument neck (1b) received between the retaining arms (5). The base (4) and the two retaining arms (5) are coupled to each other by at least one connecting member (6). Furthermore, at least one spring (7) is provided which prestresses the base (4) into a rest position and the two retaining arms (5) into an open position. According to the invention, the connecting member (6) is designed as a connecting rod (6) rigidly coupling the base (4) to the two retaining arms (5) and prestressed by the spring (7).
