Clamp Adapter for Lever-Operated Quick Connect Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lever-operated clamps require multiple tools to adjust the position of the elastomeric bumper, which complicates the clamping process and is less efficient compared to single-knob solutions like U.S. Pat. No. 8,827,255, but still has limitations.
Innovation Solution
A clamp adapter with an upper section positioned between lever arms, secured by fasteners, and a throughbore for a slidably mounted elongated rod, allowing for adjustment and securement with a thumbscrew, enabling the adapter to move in unison with the clamp arms and simplify the adjustment process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple tools are used to adjust the position of the elastomeric bumper, then the bumper can be securely attached and positioned, but the complexity of the adjustment process increases and efficiency decreases
Solution Approach 1:
The invention combines the attachment and adjustment functions into a single integrated mechanism. The button head cap screw serves both to attach the elastomeric bumper to the clamp arm and to adjust its position, eliminating the need for multiple separate tools and operations.
Solution Approach 2:
The button head cap screw performs multiple functions: it secures the elastomeric bumper to the clamp arm, allows for position adjustment along the clamp arm, and maintains the bumper in the desired position. This multi-functional component replaces what would traditionally require multiple specialized tools.
2Ease of operation
If a single knob is used to attach and adjust the rubber bumper, then the adjustment process is simplified, but the clamp assembly still suffers from limitations in ease of operation
Solution Approach 1:
The button head cap screw design allows the operator to attach and adjust the elastomeric bumper using only one hand. The thumb can easily turn the screw head to move the bumper along the clamp arm, while the other fingers hold the clamp steady, making the adjustment process self-service and highly efficient.
3Adaptability or versatility
If the elastomeric bumper is adjustably secured to the clamp arm, then the bumper can be positioned to engage different workpieces, but the adjustment mechanism becomes more complex
Solution Approach 1:
The elastomeric bumper is made adjustable along the clamp arm through the threaded engagement with the button head cap screw. This dynamic positioning capability allows the bumper to be moved to different locations to engage various workpiece geometries, while the threaded mechanism provides simple and reliable adjustment without complex components.

AI summary
A clamp adapter for use with a lever operated quick connect clamp having spaced apart clamping arms. The clamp adapter includes a one piece body having an upper section which is slidably positioned between the clamping arms and a base which abuts against the bottom the clamping arms. Threaded fasteners secure the body to the clamping arms. An elongated rod is slidably positioned in a through bore in the body and locked in place by a bolt.
