Abstract

A broadhead for an arrow having a locking mechanism which insures true alignment of the longitudinal axis of the broadhead with the longitudinal axis of the shaft of the arrow. The shaft is fit within a longitudinal bore in the body of the broadhead and a locking nut engages external threads at an end of the broadhead which tightens the body of the broadhead about the shaft of the arrow to frictionally engage the arrow shaft within the broadhead body.

Claims

1. An arrow comprising:

a shaft defining a longitudinal axis;

a broadhead including a pointed tip at a first end and a plurality of blades, said broadhead having a longitudinal bore at a second end for accommodating said shaft and at least one longitudinal slot communicating with said bore;

an annular securing collar means removably disposed about said shaft and at least a portion of said second end of said broadhead, said collar means comprising a sleeve having an inner diameter slightly less than an outer diameter of said broadhead at said second end, said sleeve being movable in relation to said second end of said broadhead along said longitudinal axis to effect a radially inwardly directed force on said second end of said broadhead at said bore to deform said broadhead at said slot for frictionally and releasably securing said shaft within said longitudinal bore of said broadhead; and

resilient ring means disposed about said second end of said broadhead and positioned between and in contact with said collar means and said blades for urging said blades towards said tip to secure said blades to said broadhead;

wherein said second end of said broadhead includes a detent and said sleeve includes a cam surface cooperating with said detent to secure said shaft within said bore.

2. An arrow according to claim 1, wherein movement of said sleeve to secure said shaft within said bore simultaneously moves said ring means to urge said blades towards said tip.

3. An arrow comprising:

a shaft defining a longitudinal axis;

a broadhead including a pointed tip at a first end and a plurality of blades, said broadhead having a longitudinal bore at a second end for accommodating said shaft and at least one longitudinal slot communicating with said bore;

an annular securing collar means removably disposed about said shaft and at least a portion of said second end of said broadhead, said collar means comprising a sleeve having an inner diameter slightly less than an outer diameter of said broadhead at said second end, said sleeve being movable in relation to said second end of said broadhead along said longitudinal axis to effect a radially inwardly directed force on said second end of said broadhead at said bore to deform said broadhead at said slot for frictionally and releasably securing said shaft within said longitudinal bore of said broadhead; and

resilient ring means disposed about said second end of said broadhead and positioned between and in contact with said collar means and said blades for urging said blades towards said tip to secure said blades to said broadhead;

wherein said second end of said broadhead includes a cam surface which cooperates with a detent on an inner surface of said sleeve to secure said shaft within said bore.

4. A broadhead comprising:

a body member defining a longitudinal axis and having a longitudinal bore extending through a portion thereof from a first end thereof for slidably receiving and enclosing an end of an arrow shaft, said body member having at least one axial slot formed therein in communication with said bore and extending from said first end;

a plurality of blade members attached to said body member;

a pointed tip disposed at a second end of said body member opposite said first end; and

an annular securing collar comprising a sleeve having an inner diameter slightly less than an outer diameter of said first end of said body member, said sleeve being axially movable in relation to said body member with respect to said longitudinal axis and positionable about said first end of said body member to inwardly radially compress said body member proximate said axial slot to frictionally and releasably secure said end of said arrow shaft within said longitudinal bore;

wherein said first end of said body member includes a detent and said sleeve includes a cam surface cooperating with said detent to secure said shaft within said bore.

5. A broadhead comprising:

a body member defining a longitudinal axis and having a longitudinal bore extending through a portion thereof from a first end thereof for slidably receiving and enclosing an end of an arrow shaft, said body member having at least one axial slot formed therein in communication with said bore and extending from said first end;

a plurality of blade members attached to said body member;

a pointed tip disposed at a second end of said body member opposite said first end; and

an annular securing collar comprising a sleeve having an inner diameter slightly less than an outer diameter of said first end of said body member, said sleeve being axially movable in relation to said body member with respect to said longitudinal axis and positionable about said first end of said body member to inwardly radially compress said body member proximate said axial slot to frictionally and releasably secure said end of said arrow shaft within said longitudinal bore;

wherein said first end of said body member includes a cam surface which cooperates with a detent on an inner surface of said sleeve to secure said shaft within said bore.
