A power tool () includes a motor () pivotally mounted within the housing of the tool. The tool is able to accept any one of a plurality of attachment members ().

Tool body

A handle assembly for a power toolcomprises a housingdefining a handleand housing a motor for actuating an output member of the tool, such as a drill bit or jigsaw blade. The handle assembly comprises at least one flexible sheetadapted to be mounted to a surface of the handle of the power tool and having a series of protrusionsadapted to be engaged by a hand of a user of the tool. The protrusionsretain at least one gaseous vibration damping material such as air between the flexible sheetand the surface of the handle

Handle assembly for tool

A handle assembly for a power toolcomprises a housingdefining a handleand housing a motor for actuating an output member of the tool, such as a drill bit or jigsaw blade. The handle assembly comprises at least one flexible sheetadapted to be mounted to a surface of the handle of the power tool and having a series of protrusionsadapted to be engaged by a hand of a user of the tool. The protrusionsretain one or more blister packs (not shown) containing at least one vibration damping gel material between the flexible sheetand the surface of the handle

A duct mechanism for directing a flow of air onto a working member of a power cutting tool generally includes a housing, a motor in the housing, a working member actuated by means of the motor and a shoe pivotally mounted relative to the working member and adapted to engage a workpiece. The duct mechanism includes an inlet portion mounted to the housing. The inlet portion receives a stream of air from the housing. An outlet portion is connected to the shoe for directing the stream of air onto the working member in a direction transverse to a line of action of the tool. At least one connecting portion connects the inlet portion and the outlet portion. The at least one connecting portion allows the outlet portion to pivot with the shoe relative to the inlet portion.

Method and apparatus for removing dust from a workpiece

A mechanism comprises an input shaft () and an output shaft () which are co-planar. Between the input shaft and output shaft is an axis () orthogonal to both shafts about which mounting brackets () holding the input and output shafts may pivot. This permits an angular adjustment between the input and output shaft within the same plane.

Mechanism for use in a power tool and a power tool including such a mechanism

A power sander () having a housing () and a motor within the housing is disclosed. A gripping portion adapted to be engaged by a hand of a user of the sander comprises blister packs (), () comprising first and second flexible sheets defining a gel-containing chamber therebetween and containing a vibration damping gel material, the first and second sheets being sealed to each other at the periphery of each gel-containing chamber. Clamping plates (), () include a body portion and pins (not shown) adapted to extend through the periphery of a corresponding blister pack and to protrude inwardly of the surface of the housing (). The pins are then deformed by means of heat or ultrasound to secure the clamping plates (), () to the housing ().

A mechanism is disclosed for clamping a jigsaw () shoe in a desired position relative to the body of a power tool. A plurality of gear () teeth are used to allow greater torque and access as compared to prior art clamping mechanisms.

Shoe clamping mechanism for power tool and power tool incorporating such mechanism

A power tool ( ) includes a motor ( ) pivotally mounted within the housing of the tool. The tool is able to accept any one of a plurality of attachment members ( ).

Power tool

A power tool (,) includes a motor (,) pivotally mounted within the housing of the tool. The tool is able to accept any one of a plurality of attachment members (,). The motor (,) is adapted to pivot in order that accurate axial alignment with any one of the attachment members presented to the motor occurs.

A power tool (,) includes a motor (,) mounted there within. The motor has an output (,) for engagement with an input of an attachment member (,) presented thereto. The coupling between the motor output (,) and the attachment member (,) is by a snap-fit coupling achieved by way of resiliently biased arms (,) within the tool engaging with an annular recess (,) formed on the attachment member (,).

A power tool system includes a tool body in which an activation switch (,) controls a motor (,). A plurality of interchangeable tool heads (,) are able to be accepted by the power tool in order to provide a dedicated tool. A releaseable lock-off mechanism (,) is incorporated in the tool body which restrains actuation of the activation switch (,) when none of the tool heads (,) is present.

Power tool having interchangeable tool head

A power tool comprises a body (,) having a motor (,) with an output. A detachable tool head (,) is engageable with the motor output wherein the motor output has a first engagement member (,) for complimentary engagement with a second engagement member (,) on the tool head drive. The first engagement member (,) is recessed within the body (,) and accessible through an aperture (,) therein. And the second engagement member (,) is recessed within the tool head (,) and accessible through a second aperture therewithin.

A lock-off mechanism (80) for a power tool (2) comprises a longitudinally extended locking member (80) pivotally mounted within the power tool and having one end (86) resiliently biased into engagement with a power switch (12). The mechanism further comprising an actuation member extending substantially perpendicular to the locking member (80) so as to be displaceable transversely with respect to the locking member (80) and engagable therewith to effect cam engagement between a cam surface (300) of the actuation member and a cam surface (90) of the lever member (80) upon such transverse displacement of the actuation member, so as to pivotally displace the locking member (80) out of engagement with the switch (12).
