Arrowhead bushing
First Claim
1. An arrow comprising:
- a hollow arrow shaft having an inner diameter;
an arrowhead having a tip portion and a cylindrical shank portion, the cylindrical shank potion having an outer diameter; and
a bushing having a cylindrical section and a taper section, a bore extending through the tapered section of the bushing, the bore having an inner diameter at the tapered section of the bushing that is matched to the outer diameter of the cylindrical shank portion of the arrowhead to accommodate receipt of the cylindrical shank portion of the arrowhead into the tapered section of the bushing, the cylindrical section of the bushing having an outer diameter matched to the inner diameter of the hollow arrow shaft to accommodate receipt of the cylindrical section of the bushing into an end of the arrow shaft, the cylindrical shank portion of the arrowhead having smooth surfaces that engage smooth surfaces of the bore extending through the tapered section of the bushing, whereby the absence of threads and other irregularities on the engaging surfaces between the arrowhead and the bushing improve concentricity among the arrowhead, bushing and arrow shaft.

Abstract
An arrow that is easily assembled and exhibits improved concentricity between the arrowhead and the arrow shaft includes a hollow arrow shaft, an arrowhead having a tip and a cylindrical shank, and a bushing having a cylindrical section and a tapered section, wherein the cylindrical section of the bushing is received in an end of the hollow arrow shaft and secured to the hollow arrow shaft with an adhesive. The tapered section has a bore in which the shank portion of the arrowhead is received, and the shank portion of the arrowhead is secured within the bore using an adhesive. In accordance with an aspect of the invention, the cylindrical shank portion of the arrowhead has smooth surfaces that engage smooth surfaces of the bore extending through the tapered section of the bushing, whereby the absence of threads and other irregularities on the engaging surfaces between the arrowhead and the bushing improve concentricity among the arrowhead, bushing and arrow shaft.

17. An arrow kit with interchangeable parts, comprising:
-
a first arrow shaft having an inner diameter;
a second arrow shaft having an inner diameter that is different from the inner diameter of the first arrow shaft;
an arrowhead having a tip portion and a cylindrical shank portion, the cylindrical shank portion having an outer diameter;
a first bushing having a cylindrical section and a tapered section, a bore extending through the tapered section of the bushing, the bore having an inner diameter at the tapered section of the bushing that is matched to the outer diameter of the cylindrical shank portion of the arrowhead to accommodate receipt of the cylindrical shank portion of the arrowhead into the tapered section of the bushing, the cylindrical section of the bushing having an outer diameter matched to the inner diameter of the first arrow shaft to accommodate receipt of the cylindrical section of the first bushing into an end of the first arrow shaft;
and a second bushing having a cylindrical section and a tapered section, a bore extending through the tapered section of the second bushing, the bore having an inner diameter at the tapered section of the second bushing that is matched to the outer diameter of the cylindrical shank portion of the arrowhead to accommodate receipt of the cylindrical shank portion of the arrowhead into the tapered section of the second bushing, the cylindrical section of the second bushing having an outer diameter matched to the inner diameter of the second hollow arrow shaft to accommodate receipt of the cylindrical section of the second bushing into an end of the second arrow shaft;
whereby the arrowhead may be secured to either the first arrow shaft using the first bushing or to the second arrow shaft using the second bushing. - View Dependent Claims (18, 19)
