Patent ID: 10654160

Abstract:
A recoil bumper for a nail gun having a body, an axially elongated cylinder disposed within the body of the nail gun, a piston slidably movable in the cylinder, and a driver having a multi-sided cross-sectional configuration, in plan, axially extending along at least a lengthwise portion thereof. The recoil bumper includes a hollow elastomeric member through which the lengthwise portion of the driver endwise passes. The elastomeric member has first and second end faces axially spaced from each other. The first end abuts with the nail gun body while the piston impacts against the second end face during operation of the nail gun. The first end face of said elastomeric member defines a first opening. The second end face of the elastomeric member defines a closed marginal edge for a second opening. The closed marginal edge of the second opening generally corresponds in size and shape to the multi-sided cross-sectional configuration of the lengthwise portion of the driver passing therethrough such that an impact area defined by the second end face of the bumper is optimized to absorb energy imparted thereto by the piston during operation of the nail gun.
