By shifting the biasing mechanism to one side or the other, the legs are automatically deployed to either the deployed configuration or the collapsed configuration. The biasing mechanism maintains the interface with the rail when in the deployed configuration and retains the lower portions of the legs adjacent each other in the collapsed configuration.
An anti-dry fire system for a crossbow including a catch moveable between a closed position that retains the draw string in a drawn configuration and an open position that releases the draw string to a released configuration position. A sear is moveable between a de-cocked position and a cocked position coupled with the catch at an interface to retain the catch in the closed position such that after firing the crossbow the sear is retained in the de-cocked position by the catch. A dry fire lockout is moveable between a disengaged position and a lockout position that blocks the sear from moving to the de-cocked position. The dry fire lockout includes a portion located behind the draw string that engages with the arrow to move the dry fire lockout to the disengaged position. This configuration precludes the use of the most common arrow nocks (flat, half-moon, etc.), reducing the risk that a non-approved arrow will be used in the crossbow.
A crossbow including first and second flexible limbs are attached to a center rail. A draw string extends across the center rail that translates between a released configuration and a drawn configuration. A string carrier including a catch is movable between a closed position that engages the draw string and an open position that releases the draw string. The string carrier slides along the center rail to engage with the draw string in the released configuration and slides to a retracted position that locates the draw string in the drawn configuration. A retaining mechanism retains the string carrier in the retracted position and the draw string in the drawn configuration. A trigger moves the catch from the closed position to the open position to fire the crossbow when the string carrier is in the retracted position.
A cocking system for a crossbow. A string carrier slides along the center rail during movement with the draw string in the released configuration to a retracted position that locates the draw string in the drawn configuration. A trigger is positioned to move the catch from the closed position and the open position to fire the crossbow when the string carrier is in the retracted position. At least one cocking rope is configured to engage with the string carrier to retract the string carrier and the draw string to the drawn configuration. A retaining mechanism retains the string carrier in the retracted position and the draw string in the drawn configuration independent of the cocking ropes.
A crossbow including first and second flexible limbs attached to a center rail. A first cam is mounted to the first bow limb and rotatable around a first axis. A draw string is received in string guide journals and is secured to first and second cams. The draw string unwinds from the string guide journals as it translates from a released configuration to a drawn configuration. Power cables are received in first and second power cable take-up journals on each of the first and second cams. 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 and are displaced along the first and second axes away from the first and second planes of rotation of the first and second draw string journals.
A torque control system for cocking a crossbow. A cocking mechanism includes a rotating member mounted to the center rail and coupled to a flexible tension member attached to a string carrier. A cocking handle is configured to engage with the rotating member to cock the crossbow. A torque control mechanism limits output torque applied to the rotating member such that rotating the cocking handle after the string carrier is in the retracted position does not move the draw string past the drawn configuration.
A string guide for a bow including first and second cams are mounted to first and second bow limbs, respectively. Each of the cams includes a string guide journal, an upper power cable take-up journal, and a lower power cable take-up journal. The draw string is arranged in a reverse draw configuration. The upper and lower power cables are received in each of the respective upper and lower power cable take-up journals and are displaced away from the respective draw string journals as the bow is drawn from the released configuration to the drawn configuration. In one embodiment, the upper and lower power cable take-up journals are helical in configuration. As a result of this configuration the cams can rotate more than 270 degrees, and preferably more than 300 degrees, as the bow is drawn from the released configuration to the drawn configuration.
A reduced friction trigger for a crossbow including a catch moveable between a closed position that retains the draw string in a drawn configuration and an open position that releases the draw string to a released configuration position such that after firing the crossbow the catch is biased to the open position. A sear is moveable between a de-cocked position and a cocked position coupled with the catch at an interface to retain the catch in the closed position such that after firing the crossbow the sear is retained in the de-cocked position by the catch, the sear being biased to the cocked position by a sear biasing force. A low friction device is located at the interface of the catch with the sear. A force sufficient to overcome frictional forces at the interface to release the catch to the open position is less than the sear biasing force.
A string control assembly for a crossbow having a catch, a sear, a dry fire lockout and a trigger assembly. Engaging the draw string with the catch when in the open position after firing the crossbow generates a force that pushes the catch from the open position to the closed position and automatically (i) couples the sear with the catch at the interface to retain the catch in the closed position, and (ii) moves the dry fire lockout to the lockout position to block the sear from moving to the de-cocked position. In one embodiment, engaging the draw string with the catch automatically moves the safety to the safe position coupled with the sear to retain the sear in the cocked position.
A system for cocking mechanism for a crossbow that uses an elongated handle pivotally attached to the center support to move a traveler engaged with the draw string from a release configuration to a drawing configuration and into engagement with a trigger assembly. A ratcheting mechanism prevents the elongated handle from moving toward the open configuration as the crossbow is being cocked.
A crossbow including first and second cams are mounted to first and second bow limbs, respectively. Each of the cams includes a string guide journal, an upper power cable take-up journal, and a lower power cable take-up journal. The draw string is arranged in a reverse draw configuration. The upper and lower power cables are received in each of the respective upper and lower power cable take-up journals and are displaced away from the respective draw string journals as the bow is drawn from the released configuration to the drawn configuration. In one embodiment, the upper and lower power cable take-up journals are helical in configuration. As a result of this configuration the cams can rotate more than 270 degrees, and preferably more than 300 degrees, as the crossbow is drawn from the released configuration to the drawn configuration.
A string guide for a bow having a reverse draw configuration with a draw string located adjacent a down-range side of the bow in a released configuration. First and second string guides rotate around first and second axes, respectively, as the draw string is displaced from the released configuration to the drawn configuration. A first power cable take-up journal on the first string guide rotates around the first axis to take up a power cable. The first power cable take-up journal includes a width measured along the first axis at least twice a width of the first power cable. The first power cable is biased away from at least the draw string. The first power cable is translated along the first power cable take-up journal as the bow is drawn from the released configuration to the drawn configuration.
An energy storage portion for a bow and a method of configuring the same. At least one first limb has both a distal portion and a proximal portion coupled to the first side of a center support. At least one second limb has both a distal portion and a proximal portion coupled to the second side of the center support. At least one first pulley is attached to the first limb at a location between the distal and the proximal portions of the first limb and at least one second pulley is attached to the second limb at a location between the distal and the proximal portions of the second limb.
A de-cocking mechanism for a bow having an energy storage assembly mounted to a center support with a draw string that extends across the center support coupled to the energy storage assembly. The bow includes a trigger assembly that retains the draw string in a drawn configuration. The de-cocking mechanism includes a de-cocking actuator that automatically releases the draw string onto the de-cocking mechanism when the de-cocking mechanism engages with the trigger assembly. The user can then manually move the draw string from the drawn configuration to a released configuration. The de-cocking mechanism is preferably combined with a cocking mechanism.
A compound bow or crossbow employs bowstring cams with bowstring cam grooves and power cord cam grooves. Preferably a pair of generally identical power cord cam grooves are positioned axially above and below the bowstring cam groove. The power cords are anchored to a fixed anchor point, e.g., a pylon, on the near end of the riser or on the near side of the crossbow bar or stock. The power cords do not cross over to the other limb. The reduction in the number of cam wheels and pulleys and in the number of strings or cords results in greater efficiency and higher transfer of energy from the bow to the arrow or bolt. There is no drop-off in pull weight at full draw. The bolt or arrow accelerates throughout the travel of the bowstring, resulting in significantly higher velocity.
