Abstract

An arrow nock may have at least two distinct string guides each designed to receive a bowstring to fire an arrow from a bow. When the nock is connected to and aligned with the arrow, each distinct string guide may be designed, when receiving the bowstring, to rotate the arrow about its longitudinal axis with respect to the bow into one of a limited number of alignment orientations.

Claims

1. An arrow nock comprising:

an attachment surface that is configured to attach the nock to an associated arrow;

a top portion comprising;

(1) an axial centerline; and

(2) first, second and third string guide impressions;

wherein;

(A) radial is defined as a direction that;

(1) extends away from the axial centerline; and

(2) is perpendicular to the axial centerline;

(B) the arrow nock has a circumference including a maximum radially extended surface;

(C) each string guide impression;

(1) is designed to receive a portion of an associated bowstring to fire the associated arrow; and

(2) is defined by two circumferentially spaced walls separated by a floor; and

(D) each wall;

(1) extends axially to a peak;

(2) has first and second circumferentially spaced sides that are curvilinear in shape; and

(3) has at least one point that lies on the maximum radially extended surface of the circumference.

2. The arrow nock of claim 1 wherein the top portion comprises:

a fourth string guide impression.

3. The arrow nock of claim 1 wherein:

the first and second string guide impressions are designed to simultaneously receive the associated bowstring to fire the associated arrow.

4. The arrow nock of claim 1 wherein:

the top portion comprises a slot positioned on the axial centerline.

5. The arrow nock of claim 1 wherein each floor:

is curvilinear shaped; and

extends axially toward each of the corresponding walls.

6. An arrow nock comprising:

an attachment surface that is configured to attach the nock to an associated arrow;

a top portion comprising;

(1) an axial centerline; and

(2) first, second and third string guide impressions;

wherein;

(A) the arrow nock has a circumference;

(B) each string guide impression;

(1) is designed to receive a portion of an associated bowstring having a circular cross-section to fire the associated arrow; and

(2) is defined by two circumferentially spaced walls separated by a floor;

(C) each wall;

(1) extends axially to a peak; and

(2) has first and second circumferentially spaced sides that are curvilinear in shape; and

(D) when the associated bowstring is properly received in any of the string guides, the associated bowstring simultaneously contacts the corresponding floor and extends axially beyond the corresponding wall peaks.

7. The arrow nock of claim 6 wherein the top portion comprises:

a fourth string guide impression.

8. The arrow nock of claim 6 wherein:

the first and second string guide impressions are designed to simultaneously receive the associated bowstring to fire the associated arrow.

9. The arrow nock of claim 6 wherein:

the top portion comprises a slot positioned on the axial centerline.

10. The arrow nock of claim 6 wherein each floor:

is curvilinear shaped; and

extends axially toward each of the corresponding walls.

11. An arrow nock comprising:

an attachment surface that is configured to attach the nock to an associated arrow;

a top portion comprising;

(1) an axial centerline; and

(2) first, second and third string guide impressions;

wherein;

(A) radial is defined as a direction that;

(1) extends away from the axial centerline; and

(2) is perpendicular to the axial centerline;

(B) the arrow nock has a circumference;

(C) each string guide impression;

(1) is designed to receive a portion of an associated bowstring to fire the associated arrow; and

(2) is defined by two circumferentially spaced walls separated by a floor;

(D) each wall;

(1) extends axially to a peak; and

(2) has first and second circumferentially spaced sides that are curvilinear in shape; and

(E) each floor has a radially outermost point at a first axial position and a radially innermost point at a second axial position that is different from the first axial position.

12. The arrow nock of claim 11 wherein:

the attachment surface is on a first axial end of the arrow nock;

the top portion is on a second axial end of the arrow nock; and

the radially outermost point of each floor is closer to the first axial end of the arrow nock than the radially innermost point.

13. The arrow nock of claim 11 wherein each floor:

is curvilinear shaped; and

extends axially toward each of the corresponding walls.

14. The arrow nock of claim 11 wherein:

the radially innermost point of each floor is radially spaced from the axial centerline.

15. The arrow nock of claim 11 wherein the top portion comprises:

a fourth string guide impression.

16. The arrow nock of claim 11 wherein:

the first and second string guide impressions are designed to simultaneously receive the associated bowstring to fire the associated arrow.

17. The arrow nock of claim 11 wherein:

the top portion comprises a slot positioned on the axial centerline.
