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.

A bow may have a string latch that holds a bowstring and that can be moved into three distinct positions. One activator may be used to prevent the string latch from being moved into its second position. A second activator may be used to prevent the string latch from being moved into its third position. A third activator may be used to move the first and second activators to prevent the string latch from being moved into its second or third positions.

A compound bow may feature the ability to pre-store energy before the drawing back of the draw string. Various embodiments contemplate that this may allow an archer to draw back the draw string or cable, and upon reaching the let off region of the compound bow's draw profile, cause the pre-stored energy to be transferred to the energy being stored by the bow. Various embodiments contemplate that this addition of pre-stored energy may give the archer more energy, held in the draw string or cable, to transfer to an arrow upon release, propelling it at greater speeds than would have been achieved with a compound bow of equal draw weight that does not feature an energy storage mechanism. Various embodiments contemplate that a system may provide for a return position of the draw.

A crossbow includes a frame that has a front end and a stock at a rear end. A projectile moves along a projectile axis that extends between the rear end and the front end during firing. The crossbow includes a power source that is configured to fire the projectile. The crossbow includes a latch that is movable between the rear end and the front end of the frame. The latch has a main body that defines a nock aperture aligned with the projectile axis and configured to receive a portion of the projectile therein. The crossbow includes a projectile guide connected to the main body of the latch and positioned adjacent the projectile axis. The projectile guide is configured to interface with the projectile when the projectile is in a misaligned rotational position, and be positioned between portions of the projectile when the projectile is in an aligned rotational position.

In some embodiments, a crossbow cocking device comprises a rope and a hook engaged with the rope. The hook defines a longitudinal axis and comprises a valley, a surface of the valley oriented at a non-orthogonal angle to the longitudinal axis.

An archery release device and method operable to generate a pulling force are described herein. The archery release device, in an embodiment, includes a body, at least one element moveably coupled to the body, and a force generator coupled to the body. The force generator is configured to apply a pulling force that pulls the at least one element. As a result of the archery release device being uncocked, the force generator is configured to cause the at least one element to move relative to the body.

A crossbow including a riser, a limb coupled to the riser, and a cam assembly rotatably coupled to the limb about an axis of rotation. The cam assembly including a string guide defining a plane of rotation of the cam assembly about the axis of rotation and structured to support a drawstring, a drawstring attachment point structured to engage the drawstring, a power cable journal extending away from the plane of rotation along the axis of rotation and structured to support a power cable, and a power cable attachment point structured to engage the power cable. The power cable journal is shaped to displace the power cable away from the plane of rotation as the crossbow is drawn from a released configuration to a drawn configuration to provide a gap sized to permit the drawstring attachment point and the power cable attachment point to pass between the power cable and the plane of rotation.

An archery limb control system, method and bow are described herein. The archery limb control system, in an embodiment, includes an energy resource, a plurality of flexible lines, and a driver. The driver includes a support coupled to the flexible lines and a gear coupled to the support.

A sighting device for a bow which attaches to a release mechanism being used with said bow. The sighting device includes a sighting assembly, a positioning-and-orienting arm with multiple degrees of freedom, and a mounting clamp. The sighting assembly includes an annular plate, a sight eyepiece, and a telescoping support arm. The sight eyepiece is oriented normal to the annular plate and is positioned within a lateral boundary that is defined as an extension of an inner wall of the annular plate. The telescoping support arm is swivelably and adjacently connected to the annular plate and holds the sight eyepiece in place. A first end of the positioning-and-orienting arm is adjacently attached to the annular plate and a second of the positioning-and-orienting arm is attached to the mounting clamp. The mounting clamp is attached to the release mechanism, thus positioning the sighting assembly directly in front of the user's eye.

The disclosed technology includes a semi-automatic crossbow having a stock, a plurality of limbs, a drawstring, a bolt feeder, a barrel, a draw assembly, and a release. The draw assembly can be configured to automatically move the drawstring to a cocked position and the release can include a trigger and be configured to release the drawstring when the trigger is actuated. The disclosed technology can further include a truck configured to engage the drawstring and a bolt such that the bolt can be propelled forward by the truck when the drawstring is released by the release.
