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.

First claim

The invention claimed is:

1. 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.

2. The driving tool as defined in claim 1 , wherein:
the magazine and the first cylinder are disposed at a front end region of the second cylinder, and
the handle is disposed at a rear end region of the second cylinder on a side opposite to the front end region of the second cylinder.

3. The driving tool as defined in claim 1 , wherein the magazine and the first cylinder are disposed adjacent to each other.

4. The driving tool as defined in claim 1 , further comprising:
a compressed air supply passage configured to define a compressed air communication path between the first cylinder and the second cylinder, and
a valve member disposed in a portion of the compressed air supply passage that connects to the second cylinder, the valve member being configured to selectively provide or cut off communication between the first cylinder and the second cylinder.

5. The driving tool as defined in claim 4 , wherein the compressed air supply passage extends alongside the longitudinal axis of the second cylinder.

6. The driving tool as defined in claim 2 , wherein a longitudinal axis of the magazine and the longitudinal axis of the first cylinder are disposed parallel to each other.

7. The driving tool as defined in claim 1 , further comprising:
an operating member that is manually operable by a user in order to control the motor, wherein:
the first cylinder, the second cylinder, the handle and the motor are arranged to form a hollow space that is surrounded by the first cylinder, the second cylinder, the handle and the motor, and
the operating member is arranged to project into the hollow space.

8. The driving tool as defined in claim 1 , wherein the first cylinder, the second cylinder, the handle and the motor are arranged to respectively form four sides of a quadrilateral.

9. The driving tool as defined claim 1 , wherein:
a first end of the handle is connected to the second cylinder,
the handle extends in a crossing direction that crosses the longitudinal axis of the second cylinder, and
the motor and a battery, which supplies power to the motor, are disposed at a second end side of the handle in the crossing direction.

10. The driving tool as defined in claim 2 , wherein the magazine and the first cylinder are disposed adjacent to each other.

11. The driving tool as defined in claim 10 , further comprising:
a compressed air supply passage configured to define a compressed air communication path between the first cylinder and the second cylinder, and
a valve member disposed in a portion of the compressed air supply passage that connects to the second cylinder, the valve member being configured to selectively provide or cut off communication between the first cylinder and the second cylinder.

12. The driving tool as defined in claim 11 , wherein the compressed air supply passage extends alongside the longitudinal axis of the second cylinder.

13. The driving tool as defined in claim 12 , wherein a longitudinal axis of the magazine and the longitudinal axis of the first cylinder are disposed parallel to each other.

14. The driving tool as defined in claim 13 , further comprising:
an operating member that is manually operable by a user in order to control the motor, wherein:
the first cylinder, the second cylinder, the handle and the motor are arranged to form a hollow space that is surrounded by the first cylinder, the second cylinder, the handle and the motor, and
the operating member is arranged to project into the hollow space.

15. The driving tool as defined in claim 14 , wherein the first cylinder, the second cylinder, the handle and the motor are arranged to respectively form four sides of a quadrilateral.

16. The driving tool as defined claim 15 , wherein:
a first end of the handle is connected to the second cylinder,
the handle extends in a crossing direction that crosses the longitudinal axis of the second cylinder, and
the motor and a battery, which supplies power to the motor, are disposed at a second end of the handle in the crossing direction.

17. 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.
