Folding Stand Pivot Lock for Secure Benchtop Tool Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Compact power tools, such as benchtop table saws, are often too small to be conveniently used without elevating them off the ground, and existing stands lack a secure and easy-to-use mechanism for securing the tool to the stand.
Innovation Solution
A foldable stand with a securing mechanism that includes pivotable arms to grip the power tool frame members, providing a secure and tool-free locking mechanism using curved arms and cradles to stabilize the tool, allowing easy setup and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a compact power tool is used, then space savings and portability are improved, but the tool is too small to be conveniently used without elevating it off the ground
Solution Approach 1:
The patent introduces a vertical dimension by providing a stand with adjustable height legs that elevate the compact power tool from ground level to an appropriate work height. This allows the small tool to be used at a convenient height without requiring the user to bend over or stoop, thereby resolving the contradiction between compact size and operational convenience.
2Ease of operation
If a stand is used to elevate the power tool, then work height convenience is improved, but the securing mechanism is complex and difficult to use
Solution Approach 1:
The patent replaces complex mechanical securing mechanisms with a simple quick-release clamp system that uses a cam lever action. This allows the power tool to be securely fastened to the stand with a single motion, eliminating the need for multiple bolts, nuts, or complicated fastening procedures, thereby reducing device complexity while maintaining security.
Solution Approach 2:
The quick-release clamp mechanism is designed to be self-securing through its cam lever action, where the user's own motion of closing the lever automatically tightens and locks the clamp onto the power tool frame. This eliminates the need for additional tools or complex adjustment procedures, making the securing process simple and intuitive.
3Reliability
If a secure securing mechanism is implemented, then the power tool is firmly held to the stand, but the mechanism becomes difficult to operate and remove the tool
Solution Approach 1:
The quick-release clamp uses a cam lever that operates in periodic motion: pushing the lever clockwise engages and tightens the clamp securely onto the tool, while pulling it counterclockwise releases and opens the clamp. This periodic action allows the same mechanism to provide both strong securing force during operation and easy release when needed, resolving the contradiction between reliability and ease of removal.

AI summary
A folding stand with a pivoting securing mechanism to secure an object to the stand is disclosed. The stand may include two rails in the same horizontal plane and a securing mechanism that pivots about an axis which is perpendicular to that horizontal plane. The securing mechanism may be positionable in a locked and an unlocked position. The securing mechanism may include one or more arms that extends over a portion of the object in the locked position.
