Adjustable SCBA Tank Bracket With Quick-Release Cam Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanical brackets for securing cylindrical tanks, such as SCBA tanks, lack adaptability to varying tank sizes and configurations, and require reliable yet quick and easy securement and release mechanisms, especially considering the susceptibility of epoxy resin-coated tanks to damage.
Innovation Solution
A positively engaging apparatus with an adjustable upper bracket and foot plate, featuring a locking mechanism and release mechanism, allows for secure and customizable attachment of cylindrical tanks in an inverted vertical position, accommodating different tank sizes and configurations with minimal maintenance and capital costs, and enabling adjustments from the front side for quick release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed mechanical bracket is used to secure cylindrical tanks, then the securement is reliable, but the adaptability to varying tank sizes and configurations is poor
Solution Approach 1:
The bracket incorporates adjustable components including a vertically movable foot plate with retaining slots and an adjustable upper bracket with multiple attachment positions on the backing plate, allowing the clamping mechanism to adapt to different tank lengths and diameters while maintaining secure retention
Solution Approach 2:
The bracket is divided into separate adjustable components: a foot plate with multiple retaining slots, an upper bracket with adjustable attachment points, and a cam-based clamping mechanism, allowing each segment to be independently positioned to accommodate various tank configurations
2Reliability
If a complex locking mechanism is used to ensure secure retention, then the reliability improves, but the ease of operation for quick release deteriorates
Solution Approach 1:
The cam-based locking mechanism allows for periodic engagement and disengagement through rotational motion, where a single rotational action of the cam lever simultaneously releases both the upper and lower clamping elements, enabling quick release while maintaining secure retention during normal operation
Solution Approach 2:
The cam mechanism is designed to automatically engage and lock into position when the lever is rotated, with the cam profile itself providing the locking action without requiring additional locking components or complex control systems
3Strength
If a rigid clamping mechanism is used to secure tanks firmly, then the retention strength improves, but the damage to epoxy resin-coated tanks increases
Solution Approach 1:
The clamping surfaces of both the foot plate and upper bracket are covered with soft, non-marring material such as rubber or foam, providing a protective interface that distributes clamping force evenly and prevents damage to the epoxy resin coating while maintaining adequate retention strength

AI summary
A mechanical bracket for positively engaging of a generally cylindrical tank such as an SCBA tank in an inverted position mounted to a planar surface such as within the back of a fire truck seat. The apparatus includes a uniquely configured top clamping member which is pivotally mounted to selectively engage the upwardly facing bottom of the tank as well as including a bumper immediately thereadjacent which is adjustably positionable for abutment with the lower end of the tank which is facing upwardly. A uniquely configured foot plate is provided having a tank receiving zone defined therewithin for holding of the upper valving area of such tanks. A unique locking mechanism and release mechanism is also provided.
