Abstract

An arrow construction for use with a bow in hunting wild game provides an arrow shaft having a hollow interior. An arrowhead attaches to a leading end of the arrow shaft. A nock attaches to a trailing end of the arrow shaft. A stop member is provided within the shaft of the arrow and activates to an open position external to the shaft to restrain further travel of the arrowhead when it becomes embedded within the game. The stop member activates to the open position upon the arrow impacting the desired target. A slidably detachable arrowhead is also provided and is forceably detached from the leading end of the arrow upon the arrow'"'"'s impacting the desired target. The arrowhead translates along the arrow shaft in a direction toward the trailing end. Further translation of the arrowhead is prevented by an abutting engagement with the stop member in its activated position. A spring loaded nock at the trailing end of the arrow shaft is also provided and compensates for frictional losses inherited by the arrow upon disengagement of the arrow from the bowstring when the arrow is fired.

Claims

1. An arrow construction for use with a bow in hunting wild game, comprising:

a shaft having a hollow interior;

an arrowhead attached to a leading end of said shaft;

a stop member disposed in said shaft for limiting the travel of said shaft and said arrowhead into the body of said wild game in response to said arrowhead impacting said wild game, said stop member expanding radially from said shaft in response to said arrowhead impacting said wild game; and

means responsive to said arrowhead impacting said wild game for activating said stop member from a closed position within said hollow interior of said shaft to an open position outside said shaft, said stop member opening in a direction facing said arrowhead, said means for activating said stop member includes;

a stem longitudinally disposed within said hollow interior of said shaft, said stem having a first end attached to said stop member; and

a tip of said arrow spaced a predetermined distance away from said leading end of said shaft, said tip being attached to a second end of said stem opposite said first end; and

wherein said tip of said arrow is displaceable said predetermined distance upon impacting said wild game, said displacement of said tip displacing said stem and said stop member, said displacement of said stop member permitting said stop member to activate from said closed to said open position.

2. The invention as described in claim 1, wherein said stop member includes at least one extending finger, said at least one extending finger having a free end angled to engage said hide of the game in said open position, said at least one extending finger further being resiliently biased towards said open position.

3. The invention as described in claim 1, wherein said shaft has at least one slot, said at least one stop member being aligned with said at least one slot when said tip is displaced said predetermined distance, said at least one slot permitting at least one finger of said stop member to extend outwardly from said shaft.

4. The invention as described in claim 3, wherein said slot has a first end and a second end, said first end being positioned closer to said arrowhead than said second end, said second end having an edge angled at 23°

with respect to the longitudinal axis of said shaft between said first and second ends.

5. The invention as described in claim 4, wherein said arrowhead has concentric inner and outer sleeves and blades which are attached to said outer sleeve, said inner and outer sleeves engaging respectively an inner and outer surface of said shaft.

6. An arrow construction for use with a bow in hunting wild game, comprising:

a shaft having a hollow interior;

an arrowhead attached to a leading end of said shaft;

a stop member disposed in said shaft for limiting the travel of said shaft and said arrowhead into the body of said wild game in response to said arrowhead impacting said wild game, said stop member expanding radially from said shaft in response to said arrowhead impacting said wild game; and

means responsive to said arrowhead impacting said wild game for activating said stop member from a closed position within said hollow interior of said shaft to an open position outside said shaft, said stop member opening in a direction facing said arrowhead, said means for activating said stop member includes;

a bead insertable into said hollow shaft;

means for restraining the displacement of said bead in response to forces below a predetermined value; and

wherein, when inertial forces caused by the impact of said arrow with said wild game exceeds said predetermined value, said inertial forces cause said bead to travel through said hollow shaft toward and impact said stop member, said bead activating said stop member to said open position upon impact with said stop member.

7. The invention as described in claim 6, further including a displaceable member positioned within said shaft, said displaceable member having a U-shaped channel formed longitudinally therein, said stop member being housed within said U-shaped channel, said displaceable member upon being struck by said bead translates longitudinally within said shaft to align said stop member with at least one slot formed in said shaft.

8. An arrow construction for use with a bow in hunting wild game, comprising:

a shaft having a hollow interior;

an arrowhead attached to a leading end of said shaft;

a stop member disposed in said shaft for limiting the travel of said shaft and said arrowhead into the body of said wild game in response to said arrowhead impacting said wild game, said stop member expanding radially from said shaft in response to said arrowhead impacting said wild game;

means responsive to said arrowhead impacting said wild game for activating said stop member from a closed position within said hollow interior of said shaft to an open position outside said shaft, said stop member opening in a direction facing said arrowhead; and

means for detaching said arrowhead from said leading end of said arrow shaft in response to said arrow impacting said wild game, said arrowhead translating along said arrow shaft to engage said stop member in said open position as said arrow penetrates said wild game.

9. An arrow construction for use with a bow in hunting wild game, comprising:

a shaft having a hollow interior;

an arrowhead attached to a leading end of said shaft;

means disposed in said shaft for limiting the travel of said shaft and said arrowhead into the body of said wild game in response to said arrowhead impacting said wild game; and

a circular ring mounted to said arrowhead and around said shaft.

10. An arrow construction for use with a bow in hunting wild game, comprising:

a shaft having a hollow interior;

an arrowhead attached to a leading end of said shaft;

means disposed in said shaft for limiting the travel of said shaft and said arrowhead into the body of said wild game in response to said arrowhead impacting said wild game; and

means for overcoming frictional losses to said arrow due to the disengagement of a bowstring of the bow from said neck.

11. The invention as described in claim 10, wherein said means for overcoming frictional losses due to the disengagement of the bowstring from said nock is a coil spring disposed between projecting members of said nock, said spring compressing under the force of the bowstring when the bow is in a drawn position, said coil spring expanding against the bowstring as the bowstring is released to compensate for the frictional losses inherited by said arrow upon said disengagement.
