Compound Bow with Cable Change
In some embodiments, an archery bow comprises a riser, a first limb and a second limb. A first rotatable member is arranged to rotate about a first axis and a second rotatable member is arranged to rotate about a second axis. A bowstring is attached to the first rotatable member and arranged to bias the first rotatable member in a first rotational direction about the first axis. A power cable is attached to the first rotatable member. A servicing string is arranged for attachment to the first rotatable member and arranged to bias the first rotatable member in a second rotational direction about the first axis.
Gear-based archery limb control system and method having a motion generator
An archery limb control system, method and bow are described herein. The archery limb control system, in an embodiment, includes a motion generator configured to be supported by an archery bow, and the system includes one or more flexible lines configured to be coupled to the limbs of the bow. The system also includes a support configured to support the one or more flexible lines, and the system includes a gear coupled to the support.
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.
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.
Archery bow
In at least one embodiment, an archery bow comprises a riser supporting a first limb and a second limb. The first limb supports a first rotatable member that defines a first axis of rotation. The second limb supports a second rotatable member that defines a second axis of rotation. The first axis of rotation and the second axis of rotation move with respect to one another as the bow is drawn from a brace condition to a drawn condition. The bow defines a reference plane that includes the first axis of rotation and the second axis of rotation, wherein a distance between a predetermined location on the riser and the reference plane is greater in the brace condition than in the drawn condition.
CROSSBOW
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.
Gear-based limb control system and method for archery bows
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.
Crossbow de-tensioning apparatus
A crossbow de-tensioning apparatus includes, in an embodiment, a de-tensioning device configured to be coupled to a crossbow. The de-tensioning apparatus also includes at least one hook operatively coupled to the de-tensioning device. The at least one hook is configured to be hooked onto a bowstring of the crossbow.
Archery compound bow cam cover and sling device, and related systems and methods
An archery compound bow cam cover and sling device is disclosed. The cam cover and sling device can include two cam covers operable to at least partially cover cams of a compound bow. The cam cover and sling device can also include two limb tensioning members coupled to respective cam covers, operable to extend along limbs of the compound bow, and configured to couple with the compound bow at limb ends opposite the cams. The cam cover and sling device can further include a central tensioning member coupled to the two cam covers and operable to extend between the cams, wherein the central tensioning member is configured to increase tension in the limb tensioning members to secure the cam covers about the cams. In addition, the cam cover and sling device can also include a sling coupled to the two cam covers to support, and facilitate carrying, the compound bow.
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.
