Abstract

A handle frame (20;20.sup.1 ;120) for a portable power tool, wherein the portable power tool comprises a housing (10), a hammer mechanism (13) provided in the housing (10), and an elongate working implement (12) having an impact receiving end extending into the housing (10) for receiving impacts in a longitudinal direction from the hammer mechanism (13). The handle frame includes two parallel elongate side members (21) disposed on opposite sides of the housing (10) and extending in a first plane (x--x) parallel to a tool application direction, each of the side members (21) having a forward end portion (21a) located in the tool application direction and a rear end portion (21b) located in a direction opposite to the tool application direction. Mountings (16,17) are provided on the side members (21) for connecting the handle frame to the housing (10) of the portable power tool in a vibration damped manner. Two handgrips (18) laterally extend from the side members (21) for enabling manual support and control of the portable power tool during operation. A forward arcuate cross-member (23) interconnects the forward end portions (21a) of the side members (21), and a rear arcuate cross-member (22) interconnects the rear end portions (21b) of the side members (21). The forward cross-member (23) is disposed in a second plane (y--y) forming an angle with the first plane (x--x), and the forward cross-member (23) has a larger extent in a direction perpendicular to the tool application direction than the housing (10) of the portable power tool, thereby forming an auxiliary handgrip and protecting the housing (10) of the portable power tool.
