  • Publication number: 20230288168
    Abstract: A crossbow may include a main beam and a bow mechanism having a pair of outwardly extending bow limbs, a pair of bowstring wheels, a bowstring and at least one power cord that extends between the bow limbs. The crossbow may also include a traveling trigger mechanism and a drawing mechanism. The traveling trigger mechanism may hold the bowstring in the un-cocked condition. The drawing mechanism may then be operated to move the traveling trigger mechanism and thus the bow string from the un-cocked condition to a cocked condition.

  • Publication number: 20230204322
    Abstract: 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.

  • Patent number: 11592258
    Abstract: A crossbow de-cock mechanism may include a de-cock activator that is selectively movable from a first de-cock activator position that prevents de-cocking of a crossbow into a second de-cock activator position that permits de-cocking of the crossbow.

  • Patent number: 11428499
    Abstract: A crossbow may include a bowstring and a string latch that can be moved into a first string latch position that holds the bowstring in a cocked position, a second string latch position that does not hold the bowstring in the cocked position and a third string latch position. To de-cock the crossbow, a de-cock activator may be selectively movable from a first de-cock activator position that prevents the string latch from being moved into the third string latch position into a second de-cock activator position that permits the string latch to be moved into the third string latch position. When the string latch is in the first string latch position and the de-cock activator is in the second de-cock activator position: the string latch may be selectively movable into the third string latch position and then the second string latch position permitting de-cocking of the crossbow.

  • Publication number: 20220228833
    Abstract: A crossbow may include a main beam, a riser with a U-shaped opening, a pair of bow limbs and a bowstring. The riser may have limb attachment surfaces that are separated such that a minimum distance between them is at least as wide as a user's foot but not greater than about 5 inches. The riser may have a U-shaped opening that is designed to receive a user's foot.

  • Publication number: 20220138018
    Abstract: A crossbow de-cocking mechanism may include a trigger mechanism, a trigger latch mechanism and a winch assembly. A first rotational input to the winch may move a trigger latch to disengage the trigger mechanism. A second rotational input to the trigger latch, opposite to the first, may move the trigger mechanism to move a crossbow bowstring from a cocked position to an un-cocked position.
