Archery bowstring weights and related method of use
An archery bowstring weight is provided including a sleeve that is encapsulated and suspended at least partially within an overmolded polymeric body forming an exterior of the bowstring weight. The sleeve can be a metal body, such as a ring, that floats or moves inside the polymeric body when the bowstring vibrates to dampen vibration of the bowstring. The sleeve can be isolated or separated from the bowstring by an inner wall of the polymeric body that is disposed between the bowstring and the sleeve when the weight is installed on the bowstring. The oscillation of the sleeve inside the overmolded polymeric body also can attenuate string oscillation and reduce string noise. A related method is provided.
Cranking mechanism
A cranking mechanism preferably includes a planetary gear, a drive shaft, a one way bearing, a clutch assembly, and at least one drive unit. The clutch preferably includes a clutch pressure plate, a flywheel, friction surfaces and at least one friction plate. Each drive unit includes a carrier, a spool and a flywheel. The one way bearing and the clutch assembly are axial on the drive shaft. A pressure locking nut is threaded on to a threaded end of the crank shaft to exert pressure on the clutch assembly. The sun gear is fixed on the drive shaft. The at least one drive unit is axial with the drive shaft, and fixed with the carrier of the planetary gear set. The pressure locking nut is tightened against the clutch assembly to frictionally engage the drive shaft with the at least one drive unit.
Device for Measuring Arrow Location at Rest
A device is disclosed for measuring arrow position or location at rest. An example device includes a platform that mounts to an archery bow system to determine a position of an arrow shaft in relation to an inside of a riser shelf of the archery bow system for tuning or data collection. The example device also includes a first slot in the platform. A center shot indicator adjacent to the first slot references the center shot of the arrow shaft. A measurement reference is slidable, separately, in the first slot to reference center shot of the arrow shaft.
Crossbow mitt
A hand warmer for use with a long gun or crossbow having a sleeve of fabric configured to circumvolve a user's forearm. A user inserts his or her forearm at the second end of the tube. The first end of the tube is configured to attach to a long gun or crossbow. The first end can be configured with a section of fabric that fits between the barrel and pump action of a pump action shotgun. The first end can be configured to attach to the forend of a crossbow such as by hook and loop fastener, snaps, or zippers. The first end can be configured for positioning over the barrel of a rifle such that the first end is below a line of sight through a scope attached to the rifle.
Articulating Torque Spike Bow Grip Aid
Shooting accuracy in archery may be greatly improved by increasing the precision and repeatability in which an archer establishes “anchor points,” which are contact points between the archer and a drawn bow and arrow at a moment of launch. One such contact point is the fingers of the hand gripping the bow grip. The invention provides an articulating torque spike as a bow grip aid which enables an archer to repeatably grip the same location of the bow grip and maintain consistent grip firmness from one shot to the next.

BOW
A bow includes a handle and upper and lower limbs. The upper and lower limbs are formed of a laminated fiber-reinforced plastic material. The upper limb has first and second sets of fiber sheets stacked in a direction along a lateral axis. The first set of fiber sheets have fibers aligned at a first angle from a longitudinal axis, and the second set of fiber sheets having fibers aligned at a second angle from the longitudinal axis in an opposite direction. The lower limb has third and fourth sets of fiber sheets stacked in a direction along the lateral axis. The third set of fiber sheets have parallel fibers aligned at a third angle from the longitudinal axis, and the fourth set of fiber sheets having fibers aligned at a fourth angle from the longitudinal axis in an opposite direction. The angles are between 16 and 44 degrees.
Methods for hydrophobizing bowstrings
Methods for hydrophobizing bowstrings are described herein. In one aspect, the method can include applying a silicone-based hydrophobic coating to the bowstring; and curing the bowstring for a predefined period of time.
Bow crutch
An attachment for a compound bow that allows for improved carrying of the compound bow when a user has the bow in a non-shooting position. The attachment attaches to the compound bow at the threaded stabilizer receiver. The attachment can be attached to a stabilizer, or alternatively can have an extension that directly threads to the stabilizer receiver of the compound bow. The attachment can clip to a standard receiver, or alternatively can be threaded to an end of the stabilizer. The attachment can be configured such that a counterbalance weight can be attached to the attachment. The attachment is generally in a U shape or similar shape that allows for the arm or hand of a user to be positioned within the attachment.
Crossbow string drawing assist system
A crossbow string drawing assistance system includes a crossbow, a bowstring drawing assistance device and a wire separator assembly, the bowstring drawing assistance device and the wire separator assembly are mounted on different positions of the crossbow, a pull hook of the bowstring drawing assistance device can hook a bowstring of the crossbow, a pull wire is inserted through the two hooks to engage with the wire separator assembly; when the bowstring drawing assistance device continuously packs the pull wire, the pull wire on the wire separator assembly is engaged to force the bowstring to move toward the wire separator assembly until the bowstring is engaged with the engaging member, so as to complete a drawing operation. Therefore, a user can mount and dismount the bowstring drawing assistance device easily according to habit, so as to mount the bowstring drawing assistance device in a comfortable position.
