Abstract
A driving tool includes a first cylinder that generates compressed air by reciprocating movement of a first piston slidably disposed therein. A longitudinal direction of the first cylinder intersects a longitudinal direction of a second cylinder and extends alongside a magazine that feeds fasteners onto an axis of movement of a driving part of a second piston. The first piston reciprocally slides in a direction that extends alongside the magazine. A tool handle is disposed on the side of the first cylinder that is opposite from the magazine in the direction of the axis of movement.
Claims18
A driving tool configured to drive an object by striking it, comprising:
- a first cylinder having a longitudinal axis,
- a first piston slidably disposed within the first cylinder and configured to generate compressed air in the first cylinder,
- a motor configured to drive the first piston,
- a second cylinder having a longitudinal axis,
- a second piston slidably disposed within the second cylinder, the second piston having a first part configured to slide along a wall of the second cylinder and a second part connected thereto, the second part being elongated and configured to move linearly along an axis of movement to strike the object,
- a handle, and
- a magazine configured to feed the object onto the axis of movement of the second part,
- wherein:
- the first cylinder is configured to supply compressed air into the second cylinder,
- the second piston is configured to linearly move toward a front end of the second cylinder by the compressed air and thereby cause the second part to strike the object,
- the longitudinal axis of the first cylinder intersects the second cylinder and extends alongside the magazine,
- the first piston is configured to slide in a direction of the longitudinal axis of the first cylinder alongside the magazine,
- the first cylinder is located between the handle and the magazine, and
- a rotation axis of the motor extends parallel to the longitudinal axis of the second cylinder.
A pneumatic power tool configured to drive a fastener by striking it, comprising:
- a first cylinder having a first longitudinal axis lying in a first plane,
- a first piston slidably disposed within the first cylinder and configured to generate compressed air in the first cylinder,
- a motor configured to reciprocally drive the first piston,
- a second cylinder having a second longitudinal axis that intersects the first plane,
- a second piston slidably disposed within the second cylinder and having a terminal portion configured to move linearly along an axis of movement to strike the fastener,
- a compressed air supply passage fluidly connecting the first cylinder to the second cylinder,
- a magazine configured to hold and feed the fastener onto the axis of movement of the terminal portion of the second piston, wherein the magazine has a third longitudinal axis that is parallel, or substantially parallel, to the first longitudinal axis, and
- a handle disposed such that the first cylinder is located between the handle and the magazine,
- wherein a rotation axis of the motor extends parallel to the second longitudinal axis.
