Compressible archery nock
First Claim
1. A projectile having a compressible nock, the projectile comprising:
- a shaft having a front end portion and a rear end portion, the shaft having a longitudinal axis, the shaft being positionable in a wide range of rotational positions;
an arrow point positioned on the front end portion of the shaft;
a plurality of vanes extending from the shaft between the front end portion and the rear end portion;
a nock at least partially extending from the rear end portion of the shaft, the nock comprising a compressible end portion, the compressible end portion being compressible in an axial direction coincident with the longitudinal axis of the shaft irrespective of the rotational position of the shaft to maintain the nock on a bowstring when launching the projectile.

Abstract
A projectile, either a crossbow bolt or an arrow, having a compressible nock. The projectile has a shaft having a front end portion and a rear end portion, an arrow point positioned on the front end portion of the shaft, multiple vanes extending from the shaft between the front end portion and the rear end portion, and a nock at least partially extending from the rear end portion. The nock has a compressible end portion that is compressible toward the shaft to maintain the nock on a bowstring when the bolt is launched. In an example case, the rear end portion is flat at its rear surface and, when the bolt is launched from a crossbow, the bowstring deforms the compressible end portion of the nock to form a groove or notch in which the bowstring is seated while the bolt is launched.

12. A flexible nock for an archery arrow or bolt, the flexible nock comprising:
-
a front end portion configured to be inserted into an arrow or bolt, the front end portion having a longitudinal axis; a rear end portion configured to extend rearward from the arrow or bolt upon insertion of the front end portion into the arrow or bolt, the rear end portion being configured to at least partially deform toward the front end portion irrespective of a rotational position of the nock upon application of a force against the rear end portion in an axial direction that coincides with the longitudinal axis of the front end portion to maintain the nock on a bowstring when launching the arrow or bolt. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A method of nocking an archery arrow or bolt to a bowstring, the method comprising:
-
providing an arrow or bolt having a compressible rear surface and a plurality of vanes and providing a bow or crossbow having a bowstring; loading the arrow or bolt in the bow or crossbow by positioning the arrow or bolt forward of the bowstring, wherein the compressible rear surface is configured to contact the bowstring upon release; applying a force against the compressible rear surface of the arrow or bolt with the bowstring, wherein the force compresses the compressible rear surface to form a groove in the compressible rear surface where the compressible rear surface contacts the bowstring;
wherein the groove is formed in the compressible rear surface to maintain the nock on the bowstring when launching the arrow or bolt irrespective of the rotated position of the plurality of vanes relative to the bow or crossbow. - View Dependent Claims (26, 27, 28, 29)

30. A projectile having a compressible nock, the projectile comprising:
-
a shaft having a front end portion and a rear end portion, the shaft having a longitudinal axis; an arrow point positioned on the front end portion of the shaft; a plurality of vanes extending from the shaft between the front end portion and the rear end portion; a nock at least partially extending from the rear end portion of the shaft, the nock comprising a compressible end portion, the compressible end portion being compressible in an axial direction coincident with the longitudinal axis of the shaft to maintain the nock on a bowstring when launching the projectile, the compressible end portion comprising a rear surface, the rear surface being substantially flat when the compressible end portion is uncompressed and being contoured when the compressible end portion is compressed between a bowstring and the shaft.

31. A flexible nock for an archery arrow or bolt, the flexible nock comprising:
-
a front end portion configured to be inserted into an arrow or bolt, the front end portion having a longitudinal axis and being substantially rigid; a rear end portion configured to extend rearward from the arrow or bolt upon insertion of the front end portion into the arrow or bolt, the rear end portion being configured to at least partially deform toward the front end portion upon application of a force against the rear end portion in an axial direction that coincides with the longitudinal axis of the front end portion; wherein the front end portion is a separate part from the rear end portion; wherein the front end portion further comprises an internal void, the rear end portion extending at least partially into the internal void, wherein the internal void comprises a narrow portion and a broader portion and the rear end portion is retained within the internal void through the narrow and the broader portions.

32. A method of nocking an archery arrow or bolt to a bowstring, the method comprising:
-
providing an arrow or bolt having a compressible rear surface and a bow or crossbow having a bowstring; loading the arrow or bolt in the bow or crossbow by positioning the arrow or bolt forward of the bowstring, wherein the compressible rear surface is configured to contact the bowstring upon release; applying a force against the compressible rear surface of the arrow or bolt with the bowstring, wherein the force compresses the compressible rear surface to form an at least temporarily asymmetric groove in the compressible rear surface where the compressible rear surface contacts the bowstring.
