Abstract

An enhanced slide and a circumferential stop assembly for use with a bowfishing arrow may include matching shapes for engaging one another in use. The engagement of such matching shapes offers many improvements over conventional slide and stop assemblies, including an even circumferential distribution of impact between the slide and the stop as well as inhibiting relative longitudinal or rotational movement between the slide and stop assemblies. The stop assembly may further include a nock adapter for engaging a nock, thereby serving as a dual purpose adapter. For ease of use and installation, the stop assembly may be an outsert, meaning that it is adapted to fit snugly over an arrow shaft.

Claims

1. A bowfishing apparatus for use with an arrow shaft with a arrowhead portion and a nock end portion, said apparatus comprising:

a slide assembly including an interior bore and a circumferential receiver tapering radially outward toward the nock end portion of the arrow shaft, said slide assembly adapted to slide longitudinally along and rotate about the arrow shaft; and

a stop assembly adapted to be fixedly attached to the arrow shaft, said stop assembly including a circumferential dampener tapering radially outward toward the nock end portion of the arrow shaft, said dampener adapted for at least partial insertion into the receiver of the slide assembly.

2. The bowfishing apparatus of claim 1, wherein the stop assembly further includes a nock receiver for receiving at least a portion of a nock.

3. The bowfishing apparatus of claim 1, wherein the stop assembly is adapted to be fixedly attached around a circumference of an outer surface of the shaft.

4. The bowfishing apparatus of claim 1, wherein the circumferential receiver of the slide assembly includes a cavity with a first shape and the dampener of the stop assembly includes a dampener body with a second shape, and wherein the first shape matches the second shape.

5. The bowfishing apparatus of claim 4, wherein the dampener further includes a projection, and the receiver further includes a recess for receiving the projection.

6. The bowfishing apparatus of claim 5, wherein the projection comprises an O-ring adapted for insertion into the recess, thereby inhibiting longitudinal movement of the slide assembly.

7. The bowfishing apparatus of claim 5, wherein the recess comprises a wall defining a non-circular perimeter, and the projection comprises an extension member adapted to engage at least a portion of the wall, and wherein engagement of the extension member and the wall prevents relative rotation of the slide assembly and the stop assembly.

8. The bowfishing apparatus of claim 1, wherein the circumferential receiver includes a first non-circular cross-section and the dampener includes a second non-circular cross-section matching the first non-circular cross-section, said first non-circular cross-section adapted for engaging said second non-circular cross-section, and wherein engagement of the first non-circular cross-section with the second non-circular cross-section prevents relative rotation of the slide assembly and the stop assembly.

9. The bowfishing apparatus of claim 1, further including a fastener for attaching the stop assembly to the shaft, and wherein the stop assembly further includes an aperture on a radially outer surface of the stop assembly for receiving the fastener.

10. A bowfishing apparatus for use with a reel and bowfishing line, said apparatus comprising:

an arrow shaft including an arrowhead end and a nock end and defining an outer surface;

a slide assembly adapted for attachment to the bowfishing line and for longitudinal and rotational movement about the arrow shaft; and

a stop assembly covering the nock end and a nock end portion of the outer surface of the arrow shaft, said stop assembly including

a dampener for engaging the slide assembly and preventing longitudinal movement of the slide assembly beyond the nock end; and

a nock receiver for receiving a nock.

11. The bowfishing apparatus of claim 10, wherein the stop assembly includes:

a first section with a first inner diameter matching an outer diameter of the shaft, said first section for covering and contacting the nock end portion of the outer surface of the arrow shaft; and

a second section, said second section extending beyond the nock end and including the nock receiver, said nock receiver defining a second inner diameter matching an outer diameter of at least a portion of the nock;

wherein the first inner diameter is larger than the second inner diameter.

12. The bowfishing apparatus of claim 10, wherein the slide assembly includes a line receiver for engaging the bowfishing line.

13. The bowfishing apparatus of claim 10, wherein the slide assembly includes a circumferential receiver tapering outward toward the nock end, said circumferential receiver adapted for receiving the dampener.

14. The bowfishing apparatus of claim 13, wherein the dampener comprises a circumferential dampener tapering radially outward toward the nock end of the arrow shaft, said circumferential dampener adapted for at least partial insertion into the circumferential receiver the slide assembly.

15. The bowfishing apparatus of claim 14, wherein the circumferential receiver and the circumferential dampener comprise matching frustoconical shapes.

16. The bowfishing apparatus of claim 14, wherein the circumferential receiver comprises a concave shape and the circumferential dampener comprise a matching convex shape.

17. The bowfishing apparatus of claim 13, wherein the slide assembly further includes a recess and the dampener includes a projection adapted to engage the recess.

18. The bowfishing apparatus of claim 17, wherein the recess comprises a circular recess within the circumferential receiver and the projection comprises an O-ring.

19. The bowfishing apparatus of claim 17, wherein the recess comprises a wall defining a non-circular perimeter, and the projection comprises an extension member adapted to engage at least a portion of the wall, and wherein engagement of the extension member and the wall prevents relative rotation of the slide assembly and the stop assembly.

20. The bowfishing apparatus of claim 10, wherein the nock receiver is threadless, and is adapted to engage a threadless nock.
