Patent number: 4856195Abstract: A hand-held power tool, for example a reciprocating saw, a chain saw, or a hedge trimmer, has a rear handle and a T-shaped forward handle formed by a forwardly directed strut with a crossbar. Looped side handles are detachably mounted on each side of the tool. Upper legs of the side handles are detachably connected to opposite ends of the forward handle crossbar. Lower legs of the side handles are detachably connected to bosses on opposite sides of the tool's housing adjacent its bottom. The side handles can be mounted with screws, or interlocking elements, or a combination of both. Preferably the forward handle is integrally formed with an upper part of the tool's housing. Both side handles may be omitted and the tool held by the forward and rear handles, this reducing the width of the tool.Type: GrantFiled: September 26, 1988Date of Patent: August 15, 1989Assignee: Black & Decker Inc.Inventors: Horst Grossmann, Michael Stirm
