Abstract

A fastener driver includes a first nosepiece and a second nosepiece coupled to the first nosepiece with a fastener driving channel formed between the first nosepiece and the second nosepiece. A workpiece contact element is movable with respect to the first nosepiece and the second nosepiece between an extended position and a retracted position. A quick-release latch secures the first nosepiece and the second nosepiece together. The workpiece contact element is positioned between the quick-release latch and the first nosepiece.

First claim

What is claimed is:

1. A fastener driver comprising:
a first nosepiece;
a second nosepiece coupled to the first nosepiece with a fastener driving channel formed between the first nosepiece and the second nosepiece;
a workpiece contact element movable with respect to the first nosepiece and the second nosepiece between an extended position and a retracted position; and
a quick-release latch that is operable to secure the first nosepiece and the second nosepiece together,
wherein the workpiece contact element is positioned between the quick-release latch and the first nosepiece,
wherein the first nosepiece includes a groove in which the workpiece contact element is received, and
wherein the groove is formed on a surface of the first nosepiece that is opposite the fastener driving channel.

2. The fastener driver of claim 1 , wherein the workpiece contact element includes a planar portion slidably received in the groove.

3. The fastener driver of claim 2 , wherein the second nosepiece includes two hooks, respectively, positioned on opposite sides of the groove, and wherein the quick-release latch is engaged with the hooks to secure the first nosepiece and the second nosepiece together.

4. The fastener driver of claim 3 , wherein the first nosepiece defines respective apertures through which the hooks extend.

5. The fastener driver of claim 4 , wherein the quick-release latch includes a lever and a spring pivotably coupled to the lever, wherein the lever is pivotably coupled to the first nosepiece.

6. The fastener driver of claim 5 , 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 first nosepiece and the second nosepiece together.

7. The fastener driver of claim 5 , further comprising a magazine attached to the second nosepiece.

8. The fastener driver of claim 1 , wherein the groove is located in the middle of the first nosepiece between opposite lateral sides of the first nosepiece.

9. The fastener driver of claim 1 , wherein the fastener driving channel defines a driving axis and the workpiece contact element extends in the direction of the driving axis.

10. The fastener driver of claim 9 , wherein the groove is parallel with the driving axis.

11. The fastener driver of claim 1 , wherein the position of the workpiece contact element with respect to the first nosepiece, when the workpiece contact element is in the retracted position, is adjustable to adjust the depth to which a fastener is driven.

12. The fastener driver of claim 1 , further comprising a spring biasing the workpiece contact element towards the extended position.

13. The fastener driver of claim 12 , further comprising a bracket to which the workpiece contact element is coupled for movement therewith, wherein the bracket includes a seat upon which one end of the spring is supported.

14. The fastener driver of claim 13 , further comprising an adjustment knob threaded to a screw portion of the bracket, wherein the bracket and the adjustment knob translate with the workpiece contact element between the extended position and the retracted position.

15. The fastener driver of claim 14 , wherein rotation of the adjustment knob relative to the screw portion of the bracket adjusts an effective length of the combined workpiece contact element and the bracket.

16. The fastener driver of claim 15 , wherein the bracket is a first bracket, and wherein the fastener driver further comprises a second bracket having opposed flanges between which the adjustment knob is captured.

17. The fastener driver of claim 16 , wherein the screw portion of the first bracket protrudes through the flanges.

18. The fastener driver of claim 16 , wherein the second bracket includes a finger extending from one of the flanges, and wherein the fastener driver further comprises a switch actuated by the finger when the workpiece contact element is in the retracted position.
