Abstract: A ball handle assembly for a handheld tool is provided. The handheld tool includes a powered mechanism, an actuating mechanism for actuating the powered mechanism, and an elongated boom extending between the powered mechanism and the actuating mechanism. A ball handle assembly is adjustably attached to the boom to allow a user to adjust the ball handle assembly relative to the boom to provide a comfortable and ergonomic orientation regardless of the handedness of the operator. The ball handle assembly is translatable along the length of the boom, and the ball handle assembly provides for three degrees of rotation relative to the boom.

Abstract: A power tool includes a power tool housing at least partially encompassing an internal combustion engine and a harness on which the power tool housing is mounted. The harness has a pair of shoulder straps, a waist strap, and a panel connecting the shoulder straps and waist strap. The power tool housing is mounted on a frame having at least one arcuate tool-supporting member with an upper end proximate the shoulder straps and a lower end proximate the waist strap. The tool-supporting member is shaped along its vertical length such that a middle portion of the member arcs away from the panel such that there is an air-circulation space between the power tool housing and the panel. In one embodiment, the power tool is a blower and the housing has an air intake port facing the air-circulation space.

Abstract: A power tool (10) includes a power tool housing (18) at least partially-encompassing an internal combustion engine (14) and a harness (12) on which the power tool housing is mounted. The harness has a pair of shoulder straps (16), a waist strap (24), and a panel (44) connecting the shoulder' straps and waist strap. The power tool housing is mounted on a frame (30) having at least one arcuate tool-supporting member with an upper end proximate the shoulder straps and a lower end proximate the waist strap. The tool-supporting member is shaped along its vertical length such that a middle portion of the member arcs away from the panel such that there is an air-circulation space (S) between the power tool housing and the panel. In one embodiment, the power tool is a blower and the housing has an air intake port (46) facing the air-circulation space.
