Abstract

A improved nock bushing preferably includes a non-round body and a stop flange. The non-round body preferably has a square shape. A nock hole is formed through at least substantially all of a length of the non-round body to receive a projection from an arrow nock. A plurality of lightening openings are preferably formed through the non-round body. The stop flange extends from one end of the non-round body. A distance across the largest cross-section dimension of the non-round body is preferably greater than a diameter of a bushing hole in an arrow shaft. In use, the non-round body is inserted into a nock end of an arrow shaft, which flexes the nock end. The arrow shaft will want to return back to its original round shape and thus applies force to an outer surface of the non-round body.

Claims

1. An improved nock bushing for insertion into a nock end of an arrow shaft comprising:

a non-round body having an outer perimeter, a first end and a second end, a nock hole is formed through at least substantially all of a length of said non-round body starting at said first end, a portion of said outer perimeter having an interference fit with a bushing hole in a nock end of an arrow shaft, wherein a shape of said non-round body distorting a round shape of the arrow shaft after insertion into the bushing hole.

2. The improved nock bushing for insertion into a nock end of an arrow shaft of claim 1 wherein:

a stop flange is formed on said first end of said non-round body.

3. The improved nock bushing for insertion into a nock end of an arrow shaft of claim 1 wherein:

one of a radius and a chamfer are formed on said second end of said non-round body.

4. The improved nock bushing for insertion into a nock end of an arrow shaft of claim 1 wherein:

said non-round body having a square shape.

5. A decreased weight nock bushing for insertion into a nock end of an arrow shaft comprising:

a bushing body having an outer perimeter, a first end and a second end, a nock hole is formed through at least substantially all of a length of said bushing body starting at said first end, a plurality of lightening holes being formed through an outer perimeter of said bushing body to decrease weight. thereof; and

a stop flange is formed on said first end of said bushing body.

6. The decreased weight nock bushing for insertion into a nock end of an arrow shaft of claim 5 wherein:

one of a radius and a chamfer are formed on said second end of said bushing body.

7. An improved nock bushing for insertion into a nock end of an arrow shaft comprising:

a non-round body having an outer perimeter, a first end and a second end, a nock hole is formed through at least substantially all of a length of said non-round body starting at said first end, a plurality of lightening holes are formed through said non-round body, a portion of said outer perimeter having an interference fit with a bushing hole in a nock end of an arrow shaft, wherein a shape of said non-round body distorting a round shape of the arrow shaft after insertion into the bushing hole.

8. The improved nock bushing for insertion into a nock end of an arrow shaft of claim 7 wherein:

a stop flange is formed on said first end of said non-round body.

9. The improved nock bushing for insertion into a nock end of an arrow shaft of claim 7 wherein:

one of a radius and a chamfer are formed on said second end of said non-round body.

10. The improved nock bushing for insertion into a nock end of an arrow shaft of claim 7 wherein:

said non-round body having a square shape.
