Patent application numberDescriptionPublished
20090000434Handles for hand-held tools - A handle for a tool includes a handle body, an operation device and a pair of clamp halves. The operation device has an operation member operable by an operator. At least one of the clamp halves can move relative to the handle body along an axis. As the operation member is operated, the one of the handle halves moves along the axis, so that the distance between the handle halves can be changed for clamping or releasing a portion of the tool.01-01-2009
20100155095Power tool - It is an object of the invention to provide an effective technique for reducing adverse effect of a dust suction device on the operability of a power tool, in the power tool which can suck dust generated during operation. The power tool has a motor 06-24-2010
20100236801IMPACT TOOL - It is an object of the invention to provide a technique that contributes to realizing both the switch selecting function and the handle vibration-proofing function, in an impact tool which can switch an operation mode of a tool bit. An impact tool includes a motor 09-23-2010
20110008117DUST COLLECTING ATTACHMENT - It is an object of the invention to provide a technique that contributes to rationalization of dust collection, in a dust collecting attachment for use on a power tool.01-13-2011
20110114347HAND-HELD TOOL - An effective technique for detecting several load conditions different in presence or absence and magnitude of load applied to a tool bit is provided in a hand-held tool. A hand-held tool 05-19-2011
20110127058Power Tool - It is an object of the invention to provide an effective technique for a motor support structure of a power tool to reduce vibration. A representative reciprocating power tool may include a tool body, a tool bit, a grip, a motor, a tool bit side bearing, a grip side bearing, a tool bit side bearing housing, a grip and an elastic element. The tool bit side bearing housing houses the tool bit side bearing, while the grip side bearing housing houses the grip side bearing. The elastic element is disposed between the grip side bearing housing and the grip wherein the grip side bearing housing is elastically supported by the grip via the elastic element. According to the invention, because the grip is adapted to support the grip side bearing housing via the elastic element and the rigidity of the grip side bearing housing can be increased and vibration of the grip side bearing housing can be reduced. Further, the elastic element can absorb manufacturing errors caused between the tool body and the grip when the grip is mounted to the tool body.06-02-2011
