Abstract

A fastener driver includes a housing, a cylinder disposed within the housing, a piston positioned and movable within the cylinder, a driver blade attached to the piston and movable with the piston, a motor for driving movement of the piston, a battery removably coupled to the housing for supplying power tot the motor, a nosepiece at least partially defining a fastener driving track through which fasteners are driven by the driver blade, and a magazine operable to supply the fasteners to the nosepiece. The magazine is removable from the nosepiece only in response to prior removal of the battery from the housing.

First claim

What is claimed is:

1. A fastener driver comprising:
a housing;
a cylinder disposed within the housing;
a piston positioned and moveable within the cylinder;
a driver blade attached to the piston and movable with the piston;
a motor for driving movement of the piston;
a battery removably coupled to the housing for supplying power to the motor;
a nosepiece at least partially defining a fastener driving track through which fasteners are driven by the driver blade; and
a magazine operable to supply the fasteners to the nosepiece,
wherein the magazine is removable from the nosepiece only in response to prior removal of the battery from the housing, wherein the magazine includes a blocking member engageable with the battery to prevent removal of the magazine from the housing when the battery is coupled to the housing.

2. The fastener driver of claim 1 , wherein the magazine is removably coupled to the nosepiece independent of whether the battery is coupled to the housing.

3. The fastener driver of claim 1 , wherein the nosepiece is a front nosepiece, wherein the fastener driver further comprises a rear nosepiece attached to the magazine, and wherein the fastener driving track is defined between the front nosepiece and the rear nosepiece.

4. The fastener driver of claim 3 , further comprising a quick-release latch that is operable to secure the front nosepiece and the rear nosepiece together.

5. The fastener driver of claim 4 , wherein the rear nosepiece includes two hooks, respectively, positioned on opposite sides of the fastener driving track, and wherein the quick-release latch is engaged with the hooks to secure the front nosepiece and the rear nosepiece together.

6. The fastener driver of claim 5 , wherein the front nosepiece defines respective apertures through which the hooks extend.

7. The fastener driver of claim 6 , wherein the quick-release latch includes a lever and a spring pivotably coupled to the lever, wherein the lever is pivotably coupled to the front nosepiece.

8. The fastener driver of claim 7 , wherein the quick-release latch further includes spaced pins positioned on a lower end of the spring and engageable with the hooks, respectively, for securing the front nosepiece and the rear nosepiece together.

9. The fastener driver of claim 6 , wherein the magazine includes a blocking member located between a driving axis coaxial with the driver blade and the battery, and wherein the blocking member laterally protrudes from a side of the magazine closest to the battery.

10. The fastener driver of claim 9 , wherein the blocking member and the battery define a first axial gap in a direction parallel with an insertion axis of the battery when the battery is coupled to the housing to supply power to the motor.

11. The fastener driver of claim 10 , wherein the blocking member is engageable with the battery, thereby preventing further movement of the magazine in the direction parallel with the insertion axis, when the quick-release latch is disengaged from the hooks.

12. The fastener driver of claim 11 , wherein the rear nosepiece is separable from the front nosepiece by a second axial gap equal to the first axial gap when the blocking member is engaged with the battery.

13. The fastener driver of claim 12 , wherein the hooks are at least partially positioned within the respective apertures in the front nosepiece when the rear nosepiece is separated from the front nosepiece by the second axial gap.

14. The fastener driver of claim 3 , wherein the rear nosepiece and the magazine are removably coupled to the front nosepiece as a unit.

15. The fastener driver of claim 14 , further comprising an electrical switch operable to detect when the rear nosepiece is removed from the front nosepiece.

16. The fastener driver of claim 15 , wherein activation of the motor is inhibited in response to the electrical switch detecting removal of the rear nosepiece from the front nosepiece.

17. The fastener driver of claim 16 , wherein the electrical switch is coupled to the front nosepiece, and wherein the rear nosepiece includes a projection engageable with the electrical switch when the rear nosepiece is coupled to the front nosepiece.

18. The fastener driver of claim 17 , wherein the projection disengages the electrical switch in response to removal of the rear nosepiece from the front nosepiece.
