Table Saw Guard Mount Frame for Easy Blade Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing guard devices and kickback preventing claw members on table saws are difficult to mount and remove, especially when changing the saw blade, which complicates operations and maintenance.
Innovation Solution
A mount frame is detachably mounted to the upper portion of the splitter, supporting both the guard device and kickback preventing claw members, allowing them to be removed together, simplifying the process through a mount mechanism that includes a lever for easy vertical pivoting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the guard device and kickback preventing claw members are individually supported on the splitter, then they can function independently, but the mounting and removing operations become very difficult when changing the saw blade
Solution Approach 1:
The patent combines the guard device and kickback preventing claw members into a single integrated assembly that is supported together on the splitter. This allows both components to be mounted and removed as one unit, significantly simplifying the operations when changing the saw blade while maintaining their respective safety functions.
2Ease of operation
If the kickback preventing claw members are removed from the splitter, then the operability for cutting decorative laminated sheets is improved, but the saw blade changing operation becomes more difficult
Solution Approach 1:
The patent makes the support structure for the guard device and kickback preventing claw members detachable from the splitter. This allows the assembly to be dynamically adjusted - removed when cutting decorative laminated sheets to improve operability, and quickly reattached when changing the saw blade to maintain productivity.
3Shape
If the guard plate and kickback preventing claw members are vertically pivotally mounted on the splitter, then they can be positioned correctly, but the mounting and removing operations are very difficult
Solution Approach 1:
The patent segments the mounting system into a detachable support assembly that includes both the guard plate and kickback preventing claw members. This segmented design allows the entire assembly to be easily detached and reattached while maintaining the vertical pivotal positioning capability of individual components.

AI summary
A cutting including a saw blade protruding from an upper surface of the table can include a splitter positioned on the front side with respect to a cutting direction of the saw blade and in alignment with the saw blade. A guard device is provided for covering the saw blade. A kickback preventing claw member prevents the workpiece from being forced upward by the saw blade after the workpiece has been cut by the saw blade. A mount frame is detachably mounted to an upper portion of the splitter. The guard device and the kickback preventing claw member are supported on the mount frame, so that the guard device and the kickback preventing claw can be removed separately or together from the splitter.
