POWER TOOL WITH ERGONOMIC HANDGRIP

摘要

A power tool with an ergonomic handgrip includes a housing, a motor in the housing, a working end coupled to a front end of the housing, a handle extending distally from the housing, and a trigger coupled to the handle. The housing defines a tool axis, the handle defines a handle axis, and the trigger defines a trigger axis in its direction of movement. A first gripping region includes a rear concave recess on a rear end of the housing and a lateral concave recess along a lateral sidewall of the housing parallel to the tool axis. A vertical line extending from an innermost point of the rear concave recess intersects the trigger axis forward of where the trigger axis intersects the handle axis. A second gripping region includes a convex surface on a rear portion of the handle with an elliptical curvature having an eccentricity less than 0.5.

1. A power tool with an ergonomic handgrip comprising:
a housing with a rear end portion, a front end portion, and lateral sidewalls, the housing defining a tool axis; a motor disposed in the housing; a working end coupled to the front end portion of the housing, and configured to be driven by the motor; a handle with a proximal portion coupled to the housing, a distal end portion away from the housing, a rear wall portion, and a front wall portion, the handle defining a handle axis; a trigger coupled to the handle, the trigger defining a trigger axis extending in a direction of trigger movement; a first gripping region including a rear concave recess on the rear end portion of the housing and a lateral concave recess extending along one of the lateral sidewalls of the housing generally parallel to the tool axis, the rear concave recess having an innermost point that is closest to the front end portion of the housing; and a second gripping region including a convex surface on the rear wall portion of the proximal portion of the handle, wherein a vertical line extending from the innermost point generally perpendicular to the tool axis intersects the trigger axis at a first intersection point that is forward of a second intersection point where the trigger axis intersects the handle axis.
