Pivot-Bearing Handle Mount for Fold-Flat Thin-Wall Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handles with fastening plates secured in thin walls cannot be folded away, leading to protrusion and potential interference issues.
Innovation Solution
The fastening plate is modified to include a pivot bearing for the handle end, allowing it to be folded flat against the fastening surface, with optional stops for adjustable angle and self-locking mechanisms to secure the handle in place, using snap devices and friction to prevent rattling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the handle is made rigid and fixed to the fastening plate, then the handle provides stable support and structural strength, but the handle cannot be folded away and protrudes in a troublesome manner
Solution Approach 1:
The handle is transformed from a fixed rigid structure to a dynamic articulated structure. The handle comprises a first arm and a second arm connected by a pivot bearing, allowing the handle to change its configuration between extended and folded states. This dynamic capability enables the handle to be folded away when not in use while maintaining structural stability when deployed through the pivot connection and stop mechanism.
2Ease of operation
If the pivot bearing allows free movement of the handle, then the handle can be folded away easily, but the handle may rattle and become unstable under vibration load
Solution Approach 1:
The pivot bearing is designed to automatically provide friction-based stabilization. The bearing surface geometry and material selection create sufficient friction between the pivot components to prevent rattling and unwanted movement. The system self-regulates the handle's positional stability without requiring additional active control mechanisms, maintaining reliability while preserving foldability.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the handle to be easily folded away, reducing protrusion and minimizing rattling noise, while maintaining stability and ease of use.
Implementation Method 1
the snap device comprising two slides which are supported in the fastening plate in opposite directions against spring force
Implementation Method 2
the handle remains stationary in every desired position owing to the friction and clamping between the end of the wire and the wall

AI summary
A handle has at least one fastening plate or holding part which can be fastened in a through-hole in a thin wall such as a sheet-metal wall by means of snap devices. According to the invention, the fastening plate forms or carries a pivot bearing for the at least one end of a handle, or the like, which is bent, for example, from a round material such as thick wire, this end having a round cross section.
