20140215839 | POWER TOOL, SUCH AS A PORTABLE CIRCULAR SAW, HAVING IMPROVED BRAKING AND COOLING - A power tool, for example, a portable circular saw, includes a fan, a motor configured to rotate the fan, an output part or shaft driven by the motor, a motor housing that houses the motor, a grip housing connected to the motor housing, a trigger associated with the grip housing, and a brake member configured to brake a rotation of the motor, the brake member being mounted inside the grip housing. The brake member may be a resistive element of a rheostatic braking system. The housing and fan are configured such that cooling air is directed to cool the brake member. | 08-07-2014 |
20140331505 | CUTTING DEVICE - A wind shielding portion is provided in a front side of an exhaust port for cooling air from a motor such that it crosses over a lateral width with respect to a cutting direction. The cooling air which is blown to the wind shielding portion is effectively blown through a ventilation portion having a small ventilating resistance force and towards a marking line guide. Even when the cutting device main body is set at an incline, the cooling air is blown to the wind shielding portion, and is effectively blown through the ventilation portion to the marking line guide. | 11-13-2014 |
20140331506 | RECIPROCATING CUTTING TOOL - A jigsaw includes a motor, a rod having a blade attached thereto, a power transmission portion that converts rotation transmitted from the motor to vertical movement of the rod to vertically move the blade, and a counterweight that moves vertically in a direction of the vertical movement of the rod outside a range of the vertical, movement of the rod and the blade. At least a part of the counterweight is disposed so as to cross an extended line of a trajectory of the vertical movement of the rod. The counterweight moves vertically independently of the vertical movement of the rod which is produced by the power transmission portion. | 11-13-2014 |
