| 20100163265 | ELECTRICAL POWER TOOL - In view of the above problem, the present invention is to provide an electrical power tool which enables a user to intuitively grasp a rotation direction and a rotation speed of a tip tool. The electrical power tool | 07-01-2010 |
| 20100175972 | Switch devices for power tools - One aspect according to the present invention includes a switch device for a power tool. The switch device includes a switch lever operable to move between an ON position for activating the power tool and an OFF position for stopping activation of the power tool. An on-lock mechanism can lock the switch lever in the ON position. An off-lock mechanism can lock the switch lever in the OFF position. The operation for making the on-lock mechanism effective and the operation for releasing the off-lock mechanism are performed by operating an operation member in different directions from each other or by operating two separate operation members. | 07-15-2010 |
| 20100315804 | ELECTRIC POWER TOOLS - An electric power tool can include a switch and a lamp that is another member are incorporated in the housing, and the lamp is coupled to the case of the switch and assembled in the grip part integral with the switch, | 12-16-2010 |
| 20110031098 | SWITCH DEVICES - A switch device includes a switch body and an operation member. The switch body includes a case and a rotary shaft rotatably supported by the case and extending from one end of the case in an axial direction. The operation member is joined to the rotary shaft. The case has a cylindrical outer surface and the operation member has a cylindrical inner surface disposed coaxial with the cylindrical outer surface of the case. A support member is disposed at one of the cylindrical outer surface of the case and the cylindrical inner surface of the operation member and has an edge portion extending linearly along a circumferential direction of the one of the cylindrical outer surface and the cylindrical inner surface, so that the edge portion can slidably contact the other of the cylindrical outer surface of the case and the cylindrical inner surface of the operation member. | 02-10-2011 |
| 20110056813 | SWITCH DEVICES FOR POWER TOOLS - A switch device for a power tool includes a switch case and a switch lever. The switch lever extends outwardly from within the switch case. The switch lever has a rotative portion rotatably supported by a support portion of the switch case. A waterproofing member is disposed between the rotative portion and the support portion and provides a waterproof seal therebetween. | 03-10-2011 |
| 20110057584 | VARIABLE SPEED SWITCH - A switch for controlling a rotational speed of a motor includes an operation member, a first circuit, and a second circuit. The first circuit includes a brush coupled to the operation member having a contact and also includes a variable resistive plate having a resistance that changes in response to a contact position of the contact point of the brush, so that the first circuit outputs a control signal to the motor according to the contact position of the contact point. The second circuit connects the brush and the resistive plate without through the contact point when the brush is positioned at a given position relative to the resistive plate. | 03-10-2011 |
| 20110083868 | POWER TOOL - In a power tool, a housing is composed of two divisional housings to be combined together; two receptacle blocks are provided on inner surfaces of the two divisional housings, respectively, and configured to protrude opposite to each other from the inner surfaces of the two divisional housings to surround an electric component and to hold the electric component in place when the two divisional housings are combined together into the housing; and a seal layer of an elastic material is formed integrally with one or each of the two receptacle blocks. The seal layer formed on a first receptacle block is pressed against a second receptacle block or another seal layer formed on the second receptacle block to provide sealing between opposed surfaces of the two receptacle blocks when the two divisional housings are combined together. | 04-14-2011 |
