Abstract

A driving tool without necessary to secure an arrangement space dedicated to an actuator is provided. A driving tool includes: a striking unit movable to strike a fastener; a housing for supporting the striking unit; a trigger provided in the housing; a push lever provided in the housing, and a trigger valve, and the driving tool further includes: a slide member provided in the trigger; and a solenoid provided in the trigger and configured to move the slide member.

First claim

The invention claimed is:

1. A driving tool comprising:
a striking unit configured to be movable to strike a fastener;
a housing configured to support the striking unit;
an operation member provided in the housing and configured to be moved by an operational force of an operator;
a contact member provided in the housing and configured to be movable in contact with a workpiece into which the fastener is driven; and
a driving unit configured to have a standby state in which the striking unit is stopped and a movement state in which the striking unit is moved, and configured to be switched between the standby state and the movement state when a switching member moves,
wherein the driving tool further includes:
a transmission mechanism provided to be movable in the operation member and configured to have a transmission state in which a movement force of the operation member and a movement force of the contact member can be transmitted to the switching member and a disconnection state in which the movement force of the operation member and the movement force of the contact member cannot be transmitted to the switching member; and
an actuator provided in the operation member and configured to switch the transmission mechanism between the transmission state and the disconnection state,

wherein in order to switch the driving unit from the standby state to the movement state, either movement of the contact member in a state of movement of the operation member or movement of the operation member in a state of movement of the contact member can be selected,
wherein in a state of selection for the movement of the contact member in the state of the movement of the operation member to switch the driving unit from the standby state to the movement state, the actuator sets the transmission mechanism to be in the transmission state during a predetermined time from the movement of the operation member, and the actuator sets the transmission mechanism to be in the disconnection state after the predetermined time has elapsed from the movement of the operation member,
wherein the actuator includes a movable member capable of moving and stopping,
wherein, when power is supplied or stopped to the actuator, the movable member moves or stops, and
wherein, when the movable member moves, the transmission mechanism moves so that the transmission state and the disconnection state are switched.

2. The driving tool according to claim 1 ,
wherein the transmission mechanism includes:
a trigger arm provided to be movable with respect to the operation member; and
a slide member provided in the trigger arm and configured to move together with the actuator, and

the slide member is movable with respect to the trigger arm.

3. The driving tool according to claim 1 ,
wherein the housing includes:
a main body configured to support the striking unit; and
a handle configured to be connected to the main body and gripped by a hand when an operator operates the operation member, and

a power supply unit is provided in the handle, and power can be supplied from the power supply unit to the actuator.

4. The driving tool according to claim 3 , further comprising:
a control unit configured to supply or stop the power of the power supply unit to the actuator; and
an enclosure capable of housing the power supply unit and the control unit,
wherein the enclosure is attachable to and detachable from the handle.

5. The driving tool according to claim 1 , further comprising:
a pressure accumulation chamber provided in the housing and configured to contain a compressible gas;
a pressure chamber configured to move the striking unit when the compressible gas is supplied from the pressure accumulation chamber; and
a path configured to supply the compressible gas of the pressure accumulation chamber to the pressure chamber,
wherein the standby state of the driving unit is to disconnect the path, and
the movement state of the driving unit is to connect the path.

6. The driving tool according to claim 5 ,
wherein the driving unit includes a valve configured to connect and disconnect the path,
the valve includes the switching member configured to be moved by a movement force transmitted from the transmission mechanism, and
the transmission mechanism has a contact portion capable of being in contact with the switching member and a non-contact portion not being in contact with the switching member.

7. The driving tool according to claim 1 ,
wherein the actuator is a keep solenoid configured to move the movable member when the power is supplied, and stop the movable member when the supply of the power is stopped.

8. The driving tool according to claim 2 ,
wherein a holder configured to support the transmission mechanism to be movable is provided in the housing, and,
when the operator releases the operational force from the operation member, the slide member moves in contact with the holder.

9. A driving tool comprising:
a striking unit configured to be movable to strike a fastener;
a housing configured to support the striking unit;
an operation member provided in the housing and configured to be moved by an operational force of an operator;
a contact member provided in the housing and configured to be movable in contact with a workpiece into which the fastener is driven; and
a driving unit configured to have a standby state in which the striking unit is stopped and a movement state in which the striking unit is moved, and configured to be switched between the standby state and the movement state when a switching member moves,
wherein the driving tool further includes:
a transmission mechanism provided to be movable in the operation member and configured to have a transmission state in which a movement force of the operation member and a movement force of the contact member can be transmitted to the switching member and a disconnection state in which the movement force of the operation member and the movement force of the contact member cannot be transmitted to the switching member; and
an actuator provided in the operation member and configured to switch the transmission mechanism between the transmission state and the disconnection state,

wherein the transmission mechanism includes:
a trigger arm provided to be movable with respect to the operation member; and
a slide member provided in the trigger arm and configured to move together with the actuator,

wherein the slide member is movable with respect to the trigger arm,
wherein the actuator includes a movable member capable of moving and stopping,
wherein, when power is supplied or stopped to the actuator, the movable member moves or stops, and
wherein, when the movable member moves, the transmission mechanism moves so that the transmission state and the disconnection state are switched.

10. A driving tool comprising:
a striking unit configured to be movable to strike a fastener;
a housing configured to support the striking unit;
an operation member provided in the housing and configured to be moved by an operational force of an operator;
a contact member provided in the housing and configured to be movable in contact with a workpiece into which the fastener is driven; and
a driving unit configured to have a standby state in which the striking unit is stopped and a movement state in which the striking unit is moved, and configured to be switched between the standby state and the movement state when a switching member moves,
wherein the driving tool further includes:
a transmission mechanism provided to be movable in the operation member and configured to have a transmission state in which a movement force of the operation member and a movement
