Abstract

A compliant tip member for a fastening tool that includes a body having compressible and protective properties includes a forward section, a rearward section longitudinally opposite to the forward section and lateral sides connecting the forward and rearward sections. The compressible feature is in the form of a compression portion that forms at least a portion of the forward section. The compliant tip member forward section is compressible relative to the rearward section due to projections, such as wings or lobes that deform when the forward section is pressed against a workpiece by the nose of the fastening tool. The compliant tip member includes a recess within a surface between the forward section and the rearward section. The recess is shaped to receive the nosepiece of the fastening tool.

First claim

We claim:

1 . A compliant tip member for a fastening tool comprising:
a body having longitudinal axis, a forward section, a rearward section longitudinally opposite to the forward section and at least two lateral sides aligned on opposite sides of the longitudinal axis connecting the forward and rearward sections; a compression portion forming at least a portion of the forward section and being compressible relative to the rearward section; and a recess within a surface between the forward section and the rearward section, the recess being closed toward the forward section and open toward the rearward section.

2 . The compliant tip member according to claim 1 , wherein the body is unitary.

3 . The compliant tip member according to claim 1 , wherein the body is substantially resilient.

4 . The compliant tip member according to claim 1 , wherein the body is formed from an elastomeric material.

5 . The compliant tip member according to claim 1 , wherein the forward section includes a workpiece contact surface.

6 . The compliant tip member according to claim 1 , wherein the compression portion is longitudinally compressible.

7 . The compliant tip member according to claim 1 , wherein the compression portion is angularly compressible with respect to a longitudinal axis through the body.

8 . The compliant tip member according to claim 1 , wherein, the compression portion comprises at least one bore passing vertically through the forward section.

9 . The compliant tip member according to claim 8 , wherein, when compressed, the at least one bore in the compression portion deforms.

10 . The compliant tip member according to claim 1 , wherein the compression portion comprises projections protruding forwardly on the forward section.

11 . The compliant tip member according to claim 10 , wherein the projections comprise a pair of lobes, each lobe having a bore passing vertically therethrough.

12 . The compliant tip member according to claim 10 , wherein the projections comprise a pair of wings.

13 . The compliant tip member according to claim 10 , wherein the projections comprise a pair of webbed wings.

14 . The compliant tip member according to claim 1 , wherein the compression portion comprises a slot having an inner wall.

15 . The compliant tip member according to claim 14 , wherein the compression portion further comprises at least one compression limiting member protruding from the inner wall of the slot.

16 . The compliant tip member according to claim 1 , wherein the recess is configured to receive and retain a work contact element.

17 . The compliant tip member according to claim 1 , wherein the body includes a retaining portion for removably coupling the fastening tool.

18 . A compliant tip member for a fastening tool comprising:
a body having a forward section, a rearward section longitudinally opposite to the forward section and lateral sides connecting the forward and rearward sections; a pair of lobes forming at least a portion of the forward section and being compressible relative to the rearward section each lobe having a bore extending vertically through the forward section; a span portion connecting the pair of lobes; and a retaining portion for retaining a fastening tool on the body.

19 . The compliant tip member according to claim 18 , wherein the pair of lobes protrude obliquely from the forward section.

20 . The compliant tip member according to claim 18 , wherein the retaining portion comprises a recess between the forward section and the rearward section.

21 . The compliant tip member according to claim 18 , wherein the span portion is arcuate.

22 . The compliant tip member according to claim 18 , wherein the span portion and the lobes are configured to form a workpiece contact surface for the body.

23 . The compliant tip member according to claim 18 , wherein the body is substantially resilient.

24 . The compliant tip member according to claim 18 , wherein the body is formed from an elastomeric material.

25 . The compliant tip member according to claim 18 , wherein the forward section is substantially compressible relative to the rearward section.

26 . The compliant tip member according to claim 18 , wherein when compressed, at least one bore in the pair of lobes deforms.

27 . The compliant tip member according to claim 18 , wherein when compressed against a workpiece, the forward section deforms to increase a contact surface area between the compliant tip and the workpiece.

28 . A fastening tool for use in driving a fastener into a workpiece, the fastening tool comprising:
a housing assembly having a fastener drive track defined therein; a fastener driver reciprocally mounted for movement within the fastener drive track along a drive axis; a nosepiece assembly connected to the housing, the nosepiece assembly including a nose portion having a longitudinal body with a tip at a distal end; a power operated system carried by the housing and configured to drive the fastener along the drive axis out of the fastener drive track and into a workpiece through successive operating cycles each including a drive stroke and a return stroke; and a tip member disposed on the tip of the nose portion, the tip member having body formed with a forward section including a compression portion and a rearward section, the compression portion having at least one bore that deforms when the compression portion is pressed against a workpiece.

29 . The fastening tool according to claim 28 , wherein the tip member comprises a recess for retaining the tip of the nose portion.

30 . The fastening tool according to claim 28 , wherein the body is substantially resilient.

31 . The fastening tool according to claim 28 , wherein the body is formed from an elastomeric material.

32 . The fastening tool according to claim 28 , wherein the tip member is removably coupled to the nosepiece.

33 . The fastening tool according to claim 28 , wherein the unitary body comprises laterally opposing apertures for retaining a locking portion of the nosepiece.

34 . The fastening tool according to claim 28 , wherein the body includes a retaining portion for removably coupling the fastening tool.
