Abstract

A fastener driver includes a housing, a magazine coupled to the housing containing fasteners therein, and a nosepiece at least partially defining a fastener driving track into which fasteners from the magazine are individually received. A driver blade is movable from a retracted position toward an extended position during which a fastener in the fastener driving track is discharged from an opening in the nosepiece. A work accessory including a guide portion is configured to align an article with the nosepiece opening prior to attaching the article to a workpiece during a fastener driving operation, and a separate puller portion configured to apply a tensile force to an article to be attached to a workpiece during a fastener driving operation. The work accessory is adjustable relative to the nosepiece to selectively position the guide portion or the puller portion proximate the nosepiece opening.

Claims

1. A fastener driver comprising:

a housing;

a magazine coupled to the housing containing fasteners therein;

a nosepiece at least partially defining a fastener driving track into which fasteners from the magazine are individually received;

a driver blade movable from a retracted position toward an extended position during which a fastener in the fastener driving track is discharged from an opening in the nosepiece; and

a work accessory including a guide portion configured to align an article with the nosepiece opening prior to attaching the article to a workpiece during a fastener driving operation, and a separate puller portion configured to apply a tensile force to an article to be attached to a workpiece during a fastener driving operation,

wherein the work accessory is adjustable relative to the nosepiece to selectively position the guide portion or the puller portion proximate the nosepiece opening.

2. The fastener driver of claim 1, wherein the work accessory includes

a front face;

and

first and second arms extending from opposite sides of the front face engageable with the housing to support the work accessory in a first position where the guide portion is proximate the nosepiece opening, or a second position where the puller portion is proximate the nosepiece opening.

3. The fastener driver of claim 2, wherein the first arm and the second arm are oriented substantially perpendicular to the front face.

4. The fastener driver of claim 2, wherein the work accessory includes a tab on the front face that is receivable within a notch in the nosepiece in each of the first and second positions.

5. The fastener driver of claim 2, wherein the guide portion includes an arcuate groove defined in a first end of the front face, and wherein the puller portion includes a plurality of projections extending from an opposite, second end of the front face.

6. The fastener driver of claim 5, wherein in the first position of the work accessory, the first end of the front face protrudes from the nosepiece, thereby locating the arcuate groove below the nosepiece opening.

7. The fastener driver of claim 6, wherein in the second position of the work accessory, the second end of the front face protrudes from the nosepiece, thereby locating the projections below the nosepiece opening.

8. The fastener driver of claim 7, wherein the work accessory is supportable on the housing in a third position where neither of the guide portion or the puller portion protrudes from the nosepiece.

9. The fastener driver of claim 8, further comprising:

a detent on one of the housing or the work accessory; and

first and second apertures in the other of the housing or the work accessory in which the detent is selectively received,

wherein the detent is received in the first aperture to maintain the work accessory in the first position, and wherein the detent is received in the second aperture to maintain the work accessory in the second position.

10. The fastener driver of claim 9, wherein the first and second apertures are located in the first and second arms, respectively, of the work accessory.

11. The fastener driver of claim 10, further comprising a third aperture located in one of the first or second arms, wherein the detent is received in the third aperture, with the work accessory having the same orientation as in the second position, to alternatively maintain the work accessory in the third position.

12. The fastener driver of claim 9, wherein the detent is movable relative to the work accessory to selectively remove the detent from either of the first and second apertures.

13. The fastener driver of claim 9, wherein both of the first and second arms of the work accessory are movable relative to the housing to selectively remove the detent from either of the first and second apertures.

14. The fastener driver of claim 5, wherein the arcuate groove is configured to engage a wire and the projections are configured to engage a screen.

15. A method of operating a fastener driver, the method comprising:

providing a work accessory including a guide portion configured to align an article with a nosepiece opening of the fastener driver prior to attaching the article to a workpiece during a fastener driving operation, and a separate puller portion configured to apply a tensile force to an article to be attached to a workpiece during a fastener driving operation;

attaching the work accessory to a nosepiece of the fastener driver in a first position where the guide portion is proximate the nosepiece opening; and

adjusting the work accessory relative to the nosepiece from the first position to a second position where the puller portion is proximate the nosepiece opening.

16. The method of claim 15, wherein adjusting the work accessory from the first position to the second position includes removing the work accessory from the housing, rotating the work accessory from the first position to the second position, and reattaching the work accessory to the housing.

17. The method of claim 16, further comprising adjusting the work accessory from the second position to a third position, in which the puller portion is above the nosepiece opening.

18. The method of claim 17, wherein adjusting the work accessory from the second position to the third position includes removing the work accessory from the housing, translating the work accessory from the second position to the third position, and reattaching the work accessory to the housing.

19. The method of claim 18, wherein removing the work accessory from the housing includes removing a tab on the work accessory from a notch in the nosepiece and concurrently, disengaging a detent on one of the housing or the work accessory from an aperture in the other of the housing or the work accessory.

20. The method of claim 19, wherein removing the work accessory from the housing includes resiliently deflecting one of the detent or the portion of the work accessory in which the aperture is defined to permit disengagement of the detent from the aperture.
