Abstract

A strap tab assembly has a strap tab defining a substantially square-shaped locking hole located generally at a first end, and an elongated slot on a second end. The strap tab assembly includes a top cap defining a top cover, a square-shaped locking projection corresponding in shape to the locking hole, and a female portion forming a center channel and extending beyond and concentric with the locking projection. A bottom cap has a male portion adapted for being received in the center channel of the female portion to engage the top cap. The locking projection extends beyond the periphery of the female portion, and is configured and dimensioned to correspond to and engage an inner periphery of the locking hole.

First claim

The invention claimed is:

1. A strap tab assembly, comprising:
a strap tab defining a D-ring and forming a substantially square-shaped locking hole located generally at a proximal end, and an elongated slot on a distal end of the same strap tab opposite the proximal end and adapted for receiving a strap:
a top cap defining a top cover, a square-shaped locking projection corresponding in shape to the locking hole, and a female portion forming a center channel and extending beyond and concentric with the locking projection, the locking projection located between the top cover and the female portion; and
a bottom cap having a male portion adapted for being received in the center channel of the female portion, the bottom cap engaging and secured to the top cap by a fastener;
wherein the locking projection extends beyond the periphery of the female portion, and is configured and dimensioned to correspond to and engage an inner periphery of the locking hole.

2. The strap tab assembly of claim 1 , wherein the center channel axially extends through the female portion and the locking projection.

3. The strap tab assembly of claim 1 , wherein the center channel defines a generally square-shaped profile, the male portion having a generally square-shaped profile configured and dimensioned to mate with the profile of the center channel.

4. The strap tab assembly of claim 3 , wherein the male portion defines a threaded cavity concentric with the square-shaped profile thereof.

5. The strap tab assembly of claim 4 , further comprising the fastener, the top cover defining a recess for receiving the fastener and communicating with the center channel, the fastener arranged to be seated within the recess and extend into the center channel to engage the threaded cavity and secure the top cap to the bottom cap.

6. The strap tab assembly of claim 5 , wherein the fastener is arranged to be flush with the top cover when secured to the bottom cap.

7. The strap tab assembly of claim 1 , wherein the top and bottom caps are substantially flat.

8. The strap tab assembly of claim 1 , further comprising a washer located between the top and bottom caps, the washer having a central opening through which a cylindrical exterior of the female portion is extendable.

9. The strap tab assembly of claim 8 , wherein the washer is a wave ring.

10. The strap tab assembly of claim 1 , wherein the strap tab defines a recess concentric with the locking hole, the recess corresponding in shape to the top cover and the top cover is arranged flush against the strap tab within the recess.

11. The strap tab assembly of claim 1 , further comprising the fastener securing the top cap to the bottom cap, the fastener rotatable independently relative to the top and bottom caps.

12. The strap tab assembly of claim 1 , further comprising a frame element defining a hole through which a cylindrical exterior of the female portion extends and freely rotates within the hole.
