Pivoting Tool Holder Fastening for Secure One-Handed Suspension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool holders for suspension systems require significant force and special configuration to mount and dismount from suspension bars, making them cumbersome and difficult to use, especially for heavy or large objects, and lack secure attachment mechanisms.
Innovation Solution
A tool holder with a fastening device featuring a first and second portion that pivotally engage with the suspension bar's web and flanges, utilizing a joint and locking mechanism to securely attach and detach with minimal force, allowing one-handed operation and secure fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional fastening device is used to attach the tool holder to the suspension bar, then the attachment is secure and reliable, but significant force is required to mount and dismount the device
Solution Approach 1:
The fastening device incorporates a pivotable second portion that transitions between a first position for mounting and a second position for dismounting. This dynamic movement allows the device to be easily attached and detached from the suspension bar by simply pivoting the second portion, eliminating the need for significant force while maintaining secure attachment during use.
2Reliability
If a conventional fastening device is used, then attachment security is achieved, but the device cannot be easily operated with one hand
Solution Approach 1:
The pivotable second portion enables the fastening device to be operated with one hand by allowing simple rotational movement between mounted and dismounted states. The user can easily grasp and pivot the second portion without requiring two hands or excessive force, while the locking mechanism ensures secure attachment once mounted.
3Adaptability or versatility
If a standard hook arrangement is used, then various objects can be suspended, but heavy and large objects cannot be securely held
Solution Approach 1:
The dynamic pivotable mechanism allows the fastening device to securely hold heavy and large objects by transitioning to a locked position during mounting. The second portion pivots to engage with the suspension bar flange, creating a secure attachment that can support heavy loads, while still allowing easy one-handed operation for mounting and dismounting.

AI summary
A tool holder adapted for attachment to a C-shaped suspension bar (7) and comprising a hook means (2) for suspending an object and a fastening device (1) which enables the hook means (2) to be releasably attached to the suspension bar (7). The fastening device (1) comprises a first (4) and a second (5) portion for retaining engagement with the web (9) of the suspension bar (7) and its respective flanges (11, 12). The first portion (4) forms the upper portion of the fastening device, when mounted, to which portion the hook means (2) is fixedly attached either directly or indirectly. The second portion (5) of the fastening device (1) is pivotally attached to the first portion (4) by means of a joint (6), which, with the tool holder in its mounted state, is oriented parallel with and located between the flanges (11, 12) of the suspension bar.
