Multiply secured crossbow
A crossbow includes a supporting unit, a bow, a string-pulling unit, a trigger unit, a sight and a security unit. The security unit includes a lock, a lock-biasing spring and a pusher. The sight includes an unlocking window. The lock is movable in the sight corresponding to the unlocking window between a locking position and an unlocking position. In the unlocking position, the lock prevents the trigger unit from pivoting. The lock-biasing spring is inserted in the sight and adapted for pivoting the lock to the locking position. The pusher is connected to the string-pulling unit and hence movable relative to the supporting between two positions through the unlocking window. In the first position, the pusher keeps the lock in the unlocking position. In the second position, the pusher allows the lock-biasing spring to move the lock to the locking position.
Strap and rigid handgrip assembly for a bowstring release device and methods of use thereof
An apparatus includes a wrist strap, a bowstring release device, and a rigid handgrip. The release device is pivotably connected to the wrist strap, and has bowstring retention/release and trigger mechanisms. The handgrip pivots with respect to the wrist strap or release device or both. In a first relative configuration, a grip portion of the handgrip extends transversely away from the release device; in a second relative configuration, the grip portion of the handgrip extends obliquely rearward away from the release device. After drawing the bow by pulling with the wrist strap and handgrip, the trigger can be actuated while continuing to grip the handgrip or after releasing the handgrip (and optionally moving the handgrip to the second relative configuration).
ARCHERY RELEASE AID MOUNT
An archery release aid mount includes an attachment mechanism configured to rigidly attach the archery release aid to a bow. A securing device is configured to receive an archery release aid. The securing device includes a securing device that upon the archery release aid mount receiving the archery release aid, holds the archery release aid securely, and that is configured to allow a user to without tools remove the archery release aid from the archery release aid mount when the user wants to use the archery release aid during archery.
Crossbow with Pulleys that Rotate Around Stationary Axes
A crossbow including a frame with a riser and a center rail. First and second flexible limbs are attached to the riser. A draw string is received in string guide journals in first and second cams rotatably attached to the frame. The draw string unwinds from the string guide journals as it translates between a released configuration and a drawn configuration. The first and second cams include at least first and second power cable take-up journals, respectively. At least first and second power cables are attached to the first and second limbs and received in the first and second power cable take-up journals, respectively. As the crossbow is drawn from the released configuration to the drawn configuration the first and second power cables wrap onto the respective first and second power cable take-up journals.
ARCHERY RELEASE
The present disclosure provides an archery release that embodies many of the desirable features of prior art archery releases while avoiding many of the disadvantages of prior art archery releases. In one embodiment, a novel tension activated wrist strap index finger trigger release is provided.
Crossbow with an effort-saving safety element
A crossbow-used trigger assembly includes a casing, a connector, a trigger, a safety element, and a shield. The casing includes a trigger pivot, a latch pivot, and a first groove in communication with a second groove. The safety element is movable in the first groove. The connector is movable in the second groove. The trigger is pivotally supported on the trigger pivot and includes a front end and a rear end pivotally connected to the connector. The latch is pivotally supported on the latch pivot. A spring biases the latch towards the front end of the trigger. Another spring biases the trigger to keep the connector from the first groove. The shield is pivotally supported on the trigger pivot and includes a protuberance extending beyond the front end of the trigger to abut against the latch.
CROSSOVER CROSSBOW
A crossbow includes a frame, a riser coupled to the frame, a first flexible limb, a second flexible limb, a third flexible limb, and a fourth flexible limb. A first cam assembly couples to the first flexible limb and the second limb and includes a first draw string journal, a first power cable journal, and a second power cable journal. A second cam assembly couples to the third flexible limb and the fourth flexible limb and includes a second draw string journal, a third power cable journal, and a fourth power cable journal. A draw string is received in the first draw string journal and the second draw string journal. Power cables cross over the center rail, above and below the draw string, and are received in the first power cable journal, the second power cable journal, the third power cable journal, and the fourth power cable journal, respectively.
Back-tension handheld archery release
A back-tension handheld archery release includes a handle and a sear assembly adjustably connected with the handle to lengthen and shorten a head release distance. The sear assembly includes a first sear and a click sear which is adjustable to control a click distance prior to firing a shot. In addition, the degree of rotation of the first and click sears relative to the head is adjustable to control the head speed of the sear assembly when the release is operated to release a bowstring and fire a shot.
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.
Range finder with bow release
The range finder bow release may comprise a cuff, a support armature, a bow release, and a range finder. The cuff may be adapted to be worn on a forearm of an archer. The support armature may be coupled to the cuff and may be adapted to position the bow release adjacent to a hand of the archer. The bow release may be a mechanical aid for releasing a bow string more precisely than the archer's fingers. The range finder may be an optical instrument that is operable to determine the distance to a target. The range finder may be coupled to the cuff and may be adapted to be used by the archer when the archer bends an elbow, brings the range finder up to an eye, and views the target through the range finder.
