Pivoting Attachment Abutment for Gas Cylinder Protective Hood
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pivoting attachment devices for gas cylinder protective cowlings are difficult for users to easily transition from the rest position to the unfolded position for attachment, as they often become embedded in the cowling's outer wall, making it hard to grasp and deploy.
Innovation Solution
A pivoting attachment device for the protective cowling is designed to maintain a non-zero distance from the cowling's surface, featuring an abutment that stops the device's folding, allowing easy gripping and rotation from the rest to the attachment position, with a three-dimensional structure and optional abutments for secure fastening and easy handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the attachment device is designed to pivot close to the cowling surface, then the device structure is compact, but the device becomes difficult to grasp and deploy
Solution Approach 1:
The abutment is pre-positioned on the cowling surface to maintain a predetermined spacing relationship with the attachment device. This preliminary structural arrangement ensures that when the device pivots to its storage position, it naturally maintains clearance from the cowling surface without requiring active user intervention to prevent embedding.
Solution Approach 2:
The abutment acts as an intermediary element between the attachment device and the cowling surface. It provides a mechanical interface that maintains the predetermined spacing, preventing the attachment device from embedding into the cowling while allowing the device to pivot freely during deployment and storage operations.

AI summary
The invention relates to a protective cover (1) for a gas container (10), comprising a cover body (2) forming a protective shell delimiting an internal volume designed to receive all or part of the valve assembly (3), and a latching device (3) pivoting between several angular positions including a rest position in which the latching device (3) is fully retracted and a latching position in which the latching device (3) is fully extended. At least one stop (13) is arranged between the latching device (6) and the cover body (2), said latching device (6) coming into contact with said stop (13) when it is in the rest position, and being held by said stop (13) at a given non-zero distance (E) from the external surface of the cover body (2).Gas container (10) equipped with a valve block (3) and such protective cover (1), and its use for storing or distributing a gas or gas mixture.
