摘要： PROBLEM TO BE SOLVED: To provide a reciprocating saw allowing an operator to adjust the grip. SOLUTION: The power tool comprises a spindle for supporting a tool element, a body constituting a pivot axis and storing a motor, and a driving mechanism driven by the motor. The driving mechanism drives the spindle, and the body has a front end and a rear end for supporting the spindle. The grip is connected to the rear end of the body so that the body can rotate around the pivot axis. The reciprocating saw comprises a lock assembly for locking the grip at the rotated position relative to the body and a switch assembly supported at least partially on the grip. When the lock assembly is in the unlocked state, the switch assembly is preferably inoperable. When the switch assembly is in the operated state, the state of the lock assembly cannot be transferred to the unlocked state preferably. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To provide a cam-driven hammer mechanism for a power tool. SOLUTION: The cam-driven hammer mechanism 14 has a drive mechanism housing 46 connectable to the housing of a power tool, a first cam member 102, a second cam member 104, and a gear assembly 54 for connecting the first and second cam members on a driving basis to a driveshaft 42 so that they can rotate in opposite directions. The first and second cam members each have at least one cam surface 106, 122, which is oriented at a steep angle to the axis of the tool element and is complementary to and engageable with the other cam surface. The second cam member has an impact surface engaging the tool element to give it an impact. When the cam members are rotated in opposite directions, the cam surfaces engage each other and the second cam member is moved in one axial direction relative to the first cam member. As the counterrotating state of the cam members is continued, the cam surfaces disengage from each other and the second cam member is moved in the opposite axial direction relative to the first cam member to thus give an impact to the tool element.

摘要： PROBLEM TO BE SOLVED: To prolong the saw's life and to keep a noise level lower than an allowable limit. SOLUTION: A track drive assembly is removably supported on a motor- driven shaft 42 and engaged with a spindle 50. An eccentric cam member 118 is provided to perform track movement of a saw blade 58 according to rotation of the motor-driven shaft. A track regulation assembly selectively releases engagement between the spindle and the cam member at least at a part of rotation of an eccentric cam member 118 so as to vary the track route of the saw blade. A regulatable shoe assembly comprises a shoe 194; a shoe support member 202 rotatably supported by a housing; a fixing member 218 rotatably supported by a housing; and a lever 226 connected to a fixing member.

摘要： PROBLEM TO BE SOLVED: To provide a keyless blade clamp which is easy to manufacture, simple to use, and whose service life is prolonged. SOLUTION: A reciprocating tool, for example, a reciprocating saw, comprises a housing; a spindle 22 having an end part 50 designed to reciprocatively arrange in the housing and receive a saw blade; a blade clamp mechanism coupled to the spindle 22 and mounting the saw blade on the spindle 22. The blade clamp mechanism comprises an actuating member 38 mounted on the end part 50 of the spindle and movable to the spindle 22 between an engaging position and a non-engaging position; and a lock member 30 movable to the spindle 22 between a lock position workably related to actuating members 38 and 40 and locking the saw blade at the spindle 22 and a non-lock position wherein the saw blade is released. Through movement of the actuating members 38 and 40 from a non-engagement position to the engagement position, the locking member 30 is forcibly moved from the non-lock position to the lock position. Through movement of the actuating members 38 and 40 from the engagement position to then on-engagement position, the lock member 30 is forcibly moved from the lock position to the non-lock position.

摘要： PROBLEM TO BE SOLVED: To operate the above hammer both in an idle mode and in a hammer mode by providing a side wall which is arranged in a housing and has a board, and a ram capable of moving to a barrel, and forming a seal between the side wall, and the ram. SOLUTION: A rotary hammer drives a bit 42 both for the rotating drill operation round the axis 50 and the operation of reciprocating along the axis, that is, the hammering operation. A piston seal 94 forms a seal between a piston 86 and the side wall of a barrel 70, and the moving range of the seal 94 is within a rear part of the barrel 70 so that the seal 94 will not cross an idle board 74. A pneumatic driving system 26 has a ram 98, and the ram 98 is supported in the barrel 70 in such a manner as to be moved in the direction of the axis 50 to the barrel 70. An operator may press the bit 42 to a workpiece to switch the bit 42 from the idle mode to the hammer mode.

摘要： PROBLEM TO BE SOLVED: To obtain a slide dual miter saw having a simple cutting unit support mechanism low in production cost. SOLUTION: A slide dual miter saw 10 is equipped with a base 14 and the rotary stand 58 attached on the base so as to be freely rotated centering around a vertical axis. The rotary stand 58 has an almost planar rotary stand support surface 62 supporting an article to be processed thereon. A longitudinally extending support shaft 226 is attached to the rotary stand 58 in an integrally movable manner and has a longitudinal bevel angle shaft on the same plane as the rotary stand support surface. The miter saw is also equipped with the cutting unit 294 attached to the support shaft freely subjected to the longitudinal movement approaching and separating with respect to the rotary stand and the rotary movement centering around the bevel angle shaft with respect to the rotary stand.

摘要： PROBLEM TO BE SOLVED: To safely replace a saw blade by arranging an actuating link mechanism to move a lower blade guard between a peripheral position and an unperipheral position according to a movement of a saw arm. SOLUTION: When it is necessary to replace a saw blade according to specific use, a lower blade guard is manually rotated to an unperipheral position while holding a cutting unit in a noncutting position as it is. A cam-follower 638 of an actuating link mechanism engages with an idly moving surface 650 by this rotation, and prevents a descent of a saw arm 578, on the one hand, the lower blade guard is held in the unperipheral position. When the replacement of the blade is completed, the lower blade guard is released, and is turned and returned to a peripheral position by the action of energizing force of a spring 674.

摘要： PROBLEM TO BE SOLVED: To support a workpiece as near a saw blade as possible by providing a guide plate capable of being positioned at a first position for supporting the workpiece when a saw arm is disposed in a vertical attitude and disposing both ends of the workpiece at a second position for supporting it when the workpiece is subjected to compound miter cutting reversely. SOLUTION: The miter saw has an adjustable reverse guide plate 202 removably coupled to a base. The plate 202 has both ends 206, 210, selectively removable from a miter source. After both the ends 206, 210 are reversed, they are again mounted at the saw, and both the ends 206, 210 are selectively positioned so that the blade is adjacently disposed at a cutting passage. One 206 of both ends of the plate 202 has a vertical edge 214, and the end 206 is usable to support the workpiece when normal miter cutting of the workpiece is performed. The edge 214 of the plate 202 gives a large support when the normal miter cutting is performed.
