Abstract

An improved arrow tip suitable for hunting and an arrow assemblage associated therewith. The arrow tip has a tapered main body with four slots therein. Two fixed blades 180 degrees apart, are secured at the rear of the main body and at a swivel point; these fixed blades are removable, permitting the user to create a two blade embodiment by removing the fixed blades. Two angled or L-shaped blades are swivelly attached, at the swivel point, to the main body member such that the longer leg of the angled blades is contained within the slots during in-flight. The shorter leg of the angled blade is exposed during in-flight; but, upon impact and penetration, the shorter leg encounters resistance from the flesh of the animal, thereby swiveling the longer leg from the protection of the slot, and exposing the cutting edge the longer leg. The longer leg'"'"'s more lethal cutting edge creates extensive bleeding in the animal and thereby causes a faster and more humane death.

Claims

1. An improved hunting arrow comprising:

a) an arrow shaft;

b) fletchings attached to a first end of said arrow shaft; and

,

c) an arrow tip attached to a second end of said arrow shaft, said arrow tip having,

1) attachment means for securing said arrow tip to said arrow shaft,

2) an aerodynamic elongated body member secured to said attachment means at a first end thereof, a second end of said elongated body member being tapered to a point, said elongated body member having a first and second juxta-opposed slots therein, and wherein said elongated body member includes a hole therein,

3) two L-shaped blades, each of said L-shaped blades being swivelly connected to said elongated body member such that a longer leg of said L-shaped blades is containable within one of said slots, each of said L-shaped blades containing a hole therein, said holes in said L-shaped blades communicating with the hole in said elongated body member,

4) restraining means comprising a sheer member positioned in the holes in said elongated body member and both of said L-shaped blades for maintaining said longer leg of said L-shaped blades within one of said slots such that substantially upon contact with a target, said restraining means is broken by said L-shaped blades, and,

5) two rigid blades, each rigid blade attached to said elongated body member substantially at right angles to said slots.

2. The improved hunting arrow according to claim 1 wherein selected edges of said L-shaped blade are sharpened.

3. The improved hunting arrow according to claim 1 wherein said slots communicate with each other.

4. The improved hunting arrow according to claim 3 wherein a shorter leg of said L-shaped blades restrict a range of swivel of said L-shaped blades.

5. The improved hunting arrow according to claim 1 wherein said main body includes two slots for receipt of said rigid blades and means for engaging said rigid blades in said main body.

6. The improved hunting arrow according to claim 5 wherein said means for engaging includes means for pressing said rigid blades at a trailing point of said rigid blades.

7. An improved arrow tip comprising:

a) attachment means for securing said arrow tip to an arrow shaft;

b) an elongated body member secured to said attachment means at a first end thereof, a second end of said elongated body member being tapered to a point, said elongated body members having a first and second juxta-opposed slots therein; and

,

c) two L-shaped blades, each of said L-shaped blades being swivelly connected to said elongated body member such that a longer leg of said L-shaped blades is containable within said slot; and

,

d) a constraining strap composed of a heat-shrink material positioned around said elongated body member for securing the longer leg of said L-shaped blade within said slot.

8. The improved arrow tip according to claim 7 further including two rigid blades, each rigid blade attached to said elongated body member substantially at right angles to said slots.

9. The improved arrow tip according to claim 8 wherein selected edges of said L-shaped blade are sharpened.

10. The improved arrow tip according to claim 9 wherein said slots communicate with each other.

11. The improved arrow tip according to claim 8 wherein said main body includes two slots for receipt of said rigid blades and means for engaging said rigid blades in said main body.

12. The improved arrow tip according to claim 11 wherein said means for engaging includes means for pressing said rigid blades at a trailing point of said rigid blades.

13. A hunting arrow tip comprising:

a) a body member tapering from a first end to a pointed second end, said body member have two slots therein;

b) two angled blade members, each angled blade member having a long blade portion and a short blade portion arranged at an angle to each other, each of said angled blade members being swivelly attached to said body member such that,

1) in flight, the long blade portion is enclosed in one of said slots and the short blade portion is exposed, and,

2) upon impact and penetration, the short blade portion contacts body parts of an animal, forcing the long blade portion to swivel from said slot, thereby exposing a forward facing cutting edge of said long blade portion against body parts of the animal;

c) attachment means connected to said first end of said body member for securing said hunting arrow tip to an arrow; and

d) a constraining strap composed of a heat-shrink material positioned around said elongated body member for securing the long leg portion of said L-shaped blade within said slot.

14. The hunting arrow tip according to claim 13 wherein said slots are on opposite sides of said body member.

15. The hunting arrow tip according to claim 14 wherein said slots communicate with each other.

16. The hunting arrow tip according to claim 14 further including two cutting blades, said cutting blades located proximate to said first end of said body member and at right angles to said slots.

17. The hunting arrow tip according to claim 16 wherein said main body includes two slots for receipt of said cutting blades and means for engaging said cutting blades in said main body.

18. The hunting arrow tip according to claim 17 wherein said means for engaging includes means for pressing said cutting blades at a trailing point of said cutting blades.

19. An improved arrow tip comprising:

a) a main body having,

1) a sharpened first end,

2) means for attaching the main body to an arrow shaft located at a second end thereof, and,

3) at least two shorten slots extending substantially half way up said main body and juxtaposed towards the second end, each of said shorten slots having an engagement pin; and

,

b) at least two rigid blades, each of the rigid blades having a pin engagement mechanism and being positioned in one of said shorten slots such that pressure from an arrow shaft engaging said means for attaching forces said engagement mechanism against said engagement pin.

20. The improved arrow tip according to claim 19 wherein said engagement mechanism is located along one edge of said rigid blades.

21. The improved arrow tip according to claim 19 wherein said engagement mechanism is located at a leading point of said rigid blades.

22. The improved arrow tip according to claim 19 wherein said body member has two additional slots and further including, two angled blade members, each angled blade member having a long blade portion and a short blade portion arranged at an angle to each other, each of said angled blade members being swivelly attached to said body member such that,

a) in flight, the long blade portion is enclosed in one of said additional slots and the short blade portion is exposed, and,

b) upon impact and penetration, the short blade portion contacts body parts of an animal, forcing the long blade portion to swivel from said slot, thereby exposing a forward facing cutting edge of said long blade portion against body parts of the animal.
