Abstract

An arrow nock comprising a cylindrical body member having a plug shaft extending axially to one side for insertion within a tubular arrow shaft to maintain the shaft and nock in axial alignment. The nock is further provided with a grip portion which extends axially in the opposite direction from the plug shaft. The grip portion is flattened and merges with the cylindrical body member by way of an inclined surface. Disposed on opposite flat surfaces of the grip portion are pad portions facing in opposed directions and adjacent to a notch which receives the bow string. The pad portions are slightly elevated above the surface of the flattened portion. The pad portions have friction surfaces which help to grip the nock between the index and middle finger so that upon release of an arrow the incline surfaces tend to spread the finger tips and smooth surfaces adjacent to the pad portions and the recessed area at one side of the nock closest to the hand of the archer pass the fingers without engagement to minimize friction and enhance accuracy.

Claims

1. An arrow nock comprising:

a cylindrical body member, means for attaching said nock to an arrow shaft extending in one direction from said body member, a grip portion extending axially in the opposite direction from said shaft, said grip including a flattened portion symmetrical with the axis of said body member, a notch at the end of said grip portion to receive a bow string, pad portions disposed on the top and bottom of said flattened portion and adjacent said notch for engagement between the index and middle finger of an archer drawing a bow string, said pad portions being elevated above said flattened portion to afford clearance from the nock upon release of a drawn bow string.

2. The arrow nock of claim 1 wherein said means for attaching said nock to an arrow shaft comprises a plug shaft extending axially of said body member for insertion in a tubular arrow shaft.

3. The arrow nock of claim 2 wherein said shaft has longitudinally extending grooves to receive adhesive when said plug shaft is seated in an arrow shaft.

4. The arrow nock of claim 1 wherein said cylindrical body member is the same diameter as an arrow shaft to provide a continuous surface between said nock and arrow shaft.

5. The arrow nock of claim 1 wherein a tapered portion is provided between said cylindrical body member and said grip portion to engage the index and middle finger of an archer and gradually force the fingers apart upon release of said nock.

6. The arrow nock of claim 1 wherein said pad portions is textured to facilitate gripping the nock during drawing of the bow string.

7. An arrow nock as set forth in claim 1 wherein said pad portions are disposed to one side of the axis of said cylindrical body.

8. The arrow nock of claim 1 wherein said flattened portion is reduced at one side of said nock closest to the hand of an archer to afford clearance upon release of a drawn bow string.

9. An arrow nock as set forth in claim 1 in which said pad portions are disposed to one side of the axis of said cylindrical body member and wherein a recess is provided on the same side of said nock to reduce the mass and balance the nock relative to said axis.

10. An arrow nock comprising:

a cylindrical body member having a diameter equal to the diameter of the arrow shaft, a plug element extending axially of said cylindrical body member for insertion into the end of a tubular arrow shaft and to hold said body member in abutting relationship to the end of an arrow shaft, a grip portion extending axially in the opposite direction from said shaft, said grip portion including a flattened portion having a thickness less than the diameter of said body member, said grip portion merging with said body member by a tapered portion, a notch at the end of said grip portion to receive a bow string, pad portions disposed on the top and bottom of said flattened portion and adjacent said notch, said pad portions being provided with friction surfaces for gripping between the index and middle finger of an archer drawing a bow string, said pad portions being elevated above said flattened portion and projecting to one side thereof, said fingers of an archer being gradually spread by said tapered portion upon release of the nock by an archer to clear said pad portions and the surfaces of said nock upon release of an arrow.

11. The arrow nock of claim 10 wherein said flattened portion is reduced along one side to form a smooth surface facing the hand of an archer to clear the finger tips upon release of an arrow.
