Abstract: In a driving tool, during and/or after a driving operation has been completed, a restriction member is retained in an on-position by a cam. An energizing switch is retained in an on-state by an actuation portion of the restriction member. Because of this configuration, if a trigger is released during and/or after the driving operation has been completed, an electric motor continues to be activated, which causes a driver to return to a standby position.

Abstract: A gas-spring type driving tool with a charge valve, a relief valve, and an opening valve provided in an accumulation chamber. Compressed gas can be quickly charged into the accumulation chamber by connecting the charge valve to an external device. The relief valve maintains the accumulation chamber at a preset pressure. The opening valve is capable of opening the accumulation chamber quickly to the atmosphere. This allows for a quick removal of a jammed nail from a driving nose.

Abstract: A driving tool includes a tool body, a flywheel, a driver, a pressing mechanism and a solenoid. The solenoid has an actuation part configured to linearly move in a specified direction from an initial position when the solenoid is activated. The pressing mechanism includes a holder turnably supported around a rotation axis relative to the tool body, and a roller rotatably supported by the holder. The holder is turnable between a first position in which the roller is apart from the driver and a second position in which the roller abuts on the driver and presses the driver toward the flywheel to thereby enable transmission of the rotational energy to the driver. The actuation part is configured to turn the holder from the first position to the second position while moving from the initial position.

Abstract: A driving tool includes a tool body, a flywheel, a driver and a pressing mechanism. The pressing mechanism is disposed on a side opposite to the flywheel across the driver in a facing direction in which the flywheel and the driver face each other. The pressing mechanism includes a spring mechanism and a pressing roller. The spring mechanism includes a first spring part and a second spring part and is configured to be displaced along with forward movement of the driver. The pressing roller is configured to press the driver toward the flywheel in the facing direction by a biasing force of the spring mechanism in a process of the forward movement of the driver, to thereby enable transmission of the rotational energy to the driver. A spring constant of the whole spring mechanism varies according to an amount of displacement of the whole spring mechanism.

Abstract: A driving tool includes an electric motor, a battery mount that receives a battery for powering the electric motor, a flywheel that rotates by the electric motor, a magazine that loads a connected fastener rolled in a coil and including a plurality of fasteners temporarily connected in parallel, an impact driver that advances through a driving path with rotational power of the flywheel to drive the fasteners, and a feed mechanism that feeds the connected fastener by a pitch from the magazine toward the driving path.

Abstract: A nailing machine includes a tool body, a flywheel (40), a driver (3), a pressing mechanism and a return mechanism. The pressing mechanism includes a spring mechanism and a pressing roller (87). The pressing roller (87) is supported to be rotatable around a rotation axis (A2) and movable in a left-right direction, and configured to press the driver (3) toward the flywheel (40) by a biasing force of the spring mechanism in a nail-driving process in which the driver (3) moves from an initial position to a nail-driving position, to thereby enable transmission of the rotational energy to the driver (3). The pressing mechanism is configured such that the position of the pressing roller (87) relative to the driver (3) changes in the left-right direction between the nail-driving process and a return process, thereby making it impossible for the pressing roller (87) to press the driver (3) in the return process.

Abstract: A driving tool includes a driver, a first moving mechanism and a second moving mechanism. The driver is held to be linearly movable between an initial position and a driving position along a working axis. The first moving mechanism is configured to move the driver from the initial position to the driving position so as to cause the driver to drive a fastener. The second moving mechanism is configured to return the driver from the driving position to the initial position. The second moving mechanism includes an elastic member configured to generate an elastic force according to torsional moment acting around an axis of the elastic member. The elastic member is configured to return the driver to the initial position by the elastic force generated when the torsional moment acts on the elastic member in interlock with a movement of the driver to the driving position.

Abstract: A driving tool includes a tool body, a flywheel, a driver, a pressing mechanism and a return mechanism. The pressing mechanism includes a first biasing part and at least one roller. The at least one roller is supported to be rotatable around a second rotation axis extending in parallel to a first rotation axis of the flywheel and to be movable in an extending direction of the second rotation axis. The pressing mechanism is configured such that a position of the at least one roller relative to the driver changes in the extending direction of the second rotation axis between a nail-driving process and a return process, thereby making the at least one roller to be incapable of pressing the driver in the return process. A nailing machine includes a tool body, a flywheel (40), a driver (3), a pressing mechanism and a return mechanism. The pressing mechanism includes a spring mechanism and a pressing roller (87).

Abstract: A driving tool includes a flywheel, a driver held to be movable between an initial position and a driving position along an movement axis, a ring member configured to transmit rotational energy of the flywheel to the driver, and a driver moving mechanism configured to move the driver with respect to the ring member from the initial position to a transmitting position.

When the driver is moved to the transmitting position by the driver moving mechanism, the ring member is frictionally engaged with the driver and with the flywheel, rotated by the flywheel, and transmits the rotational energy to the driver, thereby pushing the driver from the transmitting position toward the driving position.

Abstract: An electric driving tool includes a motor, a driver, a movable member, and a driver-restricting mechanism. The driver is configured to be driven by the motor and to strike and eject a fastener from an outlet by moving from a standby position to a striking position along a specified travel path. The movable member is disposed in a vicinity of the outlet and held in an initial position in a non-pressed state, and configured to be moved from the initial position to a pressed position when pressed by a workpiece. The driver-restricting mechanism is configured to prevent the driver from moving to the striking position when the movable member is placed in the initial position, and to allow the driver to move to the striking position when the movable member is placed in the pressed position.

Abstract: A nail gun has a free end 19a and central potion of a trigger arm 19 positioned within a trigger 11, on an upper end 12a of a safety portion 12 and at a plunger 17, respectively. When the trigger 11 is pivoted on its pivot end 16, pivoting movement of the trigger 11 moves a pivot end 18 of the trigger arm 19 to press the central portion of the trigger arm 19 into contact with the plunger 17 and, with the plunger 17 serving as a fulcrum, to press the free end 19a downward against the upper end 12a of the safety portion 12. If downward movement of the safety portion 12 is obstructed when the trigger 11 is pivoted, the upper end 12a contacted by the free end 19a of the trigger arm 19 serves as a fulcrum around which the trigger arm 19 pivots with movement of the trigger 11, whereupon the central portion of the trigger arm 19 presses the plunger 17 inward so that an activation switch 10 activates a blade 7 to eject a nail through a nose piece 5.
