Pivotable Handle Assembly with Push-Button Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pivotable handles are limited in simplicity and ease of adjustment, often requiring unscrewing and re-screwing to change positions, and lack sufficient granularity in control over handle positioning.
Innovation Solution
A pivotable handle assembly with a rotation-blocking portion and a locking mechanism featuring a push-button and plunger system, allowing single-handed adjustment by unlocking the handle to pivot about a pivot axis, using a ball bearing and internal recess to facilitate movement and locking in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing pivotable handles use unscrewing mechanism to adjust position, then the handle can be adjusted to different positions, but the operation becomes complex and time-consuming
Solution Approach 1:
The locking mechanism is segmented into distinct functional components: a push-button for actuation, a plunger for force transmission, and a ball bearing for locking engagement. This segmentation allows each component to perform its specific function efficiently, transforming the complex unscrewing operation into a simple button press that releases the ball bearing from the recess, enabling easy handle repositioning.
2Ease of operation
If existing pivotable handles allow easy adjustment, then the operation is simple, but the control precision over handle positioning is insufficient
Solution Approach 1:
The ball bearing automatically performs the positioning function after the push-button releases it. The user simply needs to move the handle to the desired position, and the ball bearing self-locks into the recess at that position, providing precise control without requiring complex adjustment mechanisms or multiple components.
3Stability of the object's composition
If existing pivotable handles use tension retention mechanism, then the handle can be fixed in position, but the adjustment process requires unscrewing and re-screwing which is time-consuming
Solution Approach 1:
The ball bearing is pre-positioned within the recess to provide automatic locking stability. When the push-button is pressed, it preliminarily prepares the plunger to move inward, which then allows the ball bearing to be released from the recess. This preliminary action eliminates the need for time-consuming unscrewing and re-screwing operations, as the entire locking and unlocking process is achieved through a single button press.

AI summary
The present document describes a pivotable handle assembly for mounting on a support. The assembly comprises a rotation-blocking portion comprising a pivot axis, the rotation-blocking portion for being rotatable about the pivot axis and relative to the support when in an unlocked position, and when in a locked position, the rotation blocking portion for preventing its rotation about the pivot axis; a handle depending from the rotation blocking portion; and a locking mechanism comprising a push-button and a lock release. The locking mechanism is for locking the rotation-blocking portion in the locked position, and for unlocking the rotation-blocking portion in the unlocked position upon a pushing motion being applied to the push-button to actuate the lock release, the unlocked position thereby allowing the handle to be pivoted about the pivot axis.
