Abstract

An accessory for catching a fastener responsive to operation of a power tool having a working assembly for driving or removing the fastener may include a working end, a coupling end opposite the working end, and a catch portion disposed between the working end and the coupling end. The coupling end may be configured to be operably coupled to the power tool to be fixed rotationally and axially relative to an axis of the working assembly. The catch portion may extend substantially coaxial with the axis of the working assembly away from the coupling end to the working end. The working end may be configured to extend beyond a distal end of the working assembly.

First claim

That which is claimed:

1. An accessory for catching a fastener responsive to operation of a power tool having a working assembly for driving or removing the fastener, the accessory comprising:
a working end;
a coupling end opposite the working end; and
a catch portion disposed between the working end and the coupling end,
wherein the coupling end is configured to be operably coupled to the power tool to be fixed rotationally and axially relative to an axis of the working assembly,
wherein the catch portion extends substantially coaxial with the axis of the working assembly away from the coupling end to the working end, and
wherein the working end is configured to extend beyond a distal end of the working assembly,
wherein the catch portion comprises a reinforced portion and a flexible portion, and wherein the reinforced portion is disposed proximate to the coupling end, and the flexible portion extends at least from the reinforced portion to the working end,
wherein the flexible portion comprises a flexible material that is clear, transparent or see through, and
wherein the flexible portion comprises a net, mesh or lattice material.

2. The accessory of claim 1 , wherein the coupling end comprises an adjustable strap configured to engage a collar or motor housing of the power tool.

3. The accessory of claim 2 , wherein the coupling end comprises material that is extendible in diameter to extend around the collar or the motor housing, and be affixed to the collar or motor housing via the adjustable strap.

4. The accessory of claim 3 , wherein the adjustable strap comprises a hook and loop fastener.

5. The accessory of claim 3 , wherein a portion of the adjustable strap that faces the collar or motor housing comprises a non-slip material.

6. The accessory of claim 1 , wherein the flexible portion overlaps the reinforced portion over an entirety of the reinforced portion.

7. The accessory of claim 1 , wherein the reinforced portion comprises a rigid material that is clear, transparent or see through.

8. The accessory of claim 1 , wherein the flexible portion is supported by a support assembly that extends at least from the reinforced portion to the working end.

9. The accessory of claim 8 , wherein the support assembly comprises one or more tension wires configured to support the flexible portion such that the working end extends beyond the distal end of the working assembly in an untensioned state, and configured to enable the flexible portion to be altered in shape as the working end conforms to a surface that the fastener is being applied to or removed from in a tensioned state.

10. The accessory of claim 8 , further comprising padding material disposed at the working end to contact a surface that the fastener is being applied to or removed from.

11. The accessory of claim 10 , wherein the padding material is disposed in discrete intervals over the working end.

12. The accessory of claim 8 , wherein a removal hook is tethered to the catch portion.

13. The accessory of claim 12 , wherein the removal hook is tethered to the support assembly.

14. The accessory of claim 1 , wherein the reinforced portion extends from the coupling end less than half a length of the catch portion along the axis of the working assembly.

15. The accessory of claim 14 , wherein the flexible portion extends from the working end more than half the length of the catch portion along the axis of the working assembly.

16. The accessory of claim 1 , wherein a width of the catch portion increases as distance from the coupling end increases.

17. The accessory of claim 1 , wherein a diameter of the coupling end is adjustable, and a diameter of the working end is fixed.
