First Claim
Patent Images
1. A vibration control handle for a power tool, comprising:
- at least one frame member assembly attached to said power tool;
at least one handle assembly for providing user-controlled interface including directional, torsional, and axial control of said power tool;
at least one frame-member-mounted isolator plate attached to said frame member assembly at a vibration node point of said frame member assembly for dampened transmission of vibrations to said handle assembly;
at least one handle-assembly-mounted isolator plate for connection of said handle assembly to said frame-member-mounted isolator plate; and
resilient material located between said frame-member-mounted isolator plate and said handle-assembly-mounted isolator plate, wherein said resilient material dampens the vibrations transferred from said frame member assembly to said handle assembly.

Abstract
Disclosed is a vibration dampening handle for power tools. It includes a frame member attached to the power tool itself, and a handle assembly, which is attached to the frame member via connection to resilient material attached to an isolator chassis assembly located at a vibration node point of the frame member. The vibration dampening handle may also include a height adjustment mechanism.
