Abstract

A lock tab washer includes a washer body, the washer body defining a first side and a second side opposite the first side, the washer body defining a hole therethrough; an edge tab extending from the first side of the washer body, the edge tab define a first section and a second section, the second section bent relative to the first section; a nut tab extending from the second side of the washer body, the nut tab bent relative to the washer body; and a wing extending from the nut tab, the wing bent relative to the nut tab.

First claim

That which is claimed is:

1 . A lock tab washer comprising:
a washer body, the washer body defining a first side and a second side opposite the first side, the washer body defining a hole therethrough; an edge tab extending from the first side of the washer body, the edge tab defining a first section and a second section, the second section bent relative to the first section; a nut tab extending from the second side of the washer body, the nut tab bent relative to the washer body; and a wing extending from the nut tab, the wing bent relative to the nut tab.

2 . The lock tab washer of claim 1 , wherein the first section of the edge tab is substantially parallel to the washer body and the second section of the edge tab is substantially perpendicular to the washer body.

3 . The lock tab washer of claim 1 , wherein:
the edge tab is a first edge tab; the lock tab washer further comprises a second edge tab extending from the first side of the washer body; and a gap is defined between the first edge tab and the second edge tab.

4 . The lock tab washer of claim 3 , wherein the second edge tab is substantially parallel with the first edge tab.

5 . The lock tab washer of claim 3 , wherein a convex, arcuate edge portion of the washer body extends across the gap from the first edge tab to the second edge tab.

6 . The lock tab washer of claim 3 , wherein:
the second section of the first edge tab is bent relative to the first section of the first edge tab at a first bend line; the second edge tab defines a third section and a fourth section; the fourth section is bent relative to the third section at a second bend line; and the first bend line is substantially colinear with the second bend line. The lock tab washer of claim 1 , wherein: the nut tab defines a first nut tab side edge and a second nut tab side edge opposite the first nut tab side edge; the wing is a first wing extending from the first nut tab side edge; and the lock tab washer further comprises a second wing extending from the second nut tab side edge, the second wing bent relative to the nut tab.

8 . The lock tab washer of claim 1 , wherein the second section of the edge tab is bent in a first direction, and the nut tab is bent in a second direction opposite the first direction.

9 . The lock tab washer of claim 8 , wherein:
the second section of the edge tab is bent about 90° relative to the first section in the first direction; and the nut tab is bent about 90° relative to the washer body in the second direction.

10 . The lock tab washer of claim 9 , wherein the wing is oriented at about 90° relative to the washer body.

11 . The lock tab washer of claim 1 , wherein the washer body defines a relief notch formed at the second side, the relief notch defining a shoulder of the washer body.

12 . The lock tab washer of claim 11 , wherein the relief notch is a curvilinear bend relief notch, and the curvilinear bend relief notch is recessed into the washer body adjacent to the nut tab to facilitate bending the nut tab relative to the washer body.

13 . The lock tab washer of claim 12 , wherein a width of the washer body at the second side is less than the width of the washer body at the first side.

14 . The lock tab washer of claim 1 , wherein the wing is bent relative to the nut tab towards the second side of the washer body at about a 120° angle.

15 . The lock tab washer of claim 1 , wherein a distal end of the edge tab is curved.

16 . The lock tab washer of claim 1 , wherein a distal edge of the wing opposite the nut tab is curved.

17 . The lock tab washer of claim 1 , wherein the lock tab washer is substantially symmetric about a longitudinal axis.
