  • Patent number: 10760875
    Abstract: A replacement buttstock includes a stock body and a locking lever assembly. The stock body has an elongated receiving chamber for receiving a connecting extension of a rifle. The locking lever assembly includes a lever element, a locking pin, a stopper element and a restoring element. The stopper element is operated to allow the lever element to move to an unlock state in which the locking pin is driven to move out of the receiving chamber for unlocking the connecting extension, so that the buttstock is convenient and easy to be quickly assembled with and detached from the rifle while the user does not have to change his or her original aiming gesture.

  • Patent number: 10215520
    Abstract: A safety device connected to a shooting device or a crossbow includes a safety member that is moved to restrict an activating member from pivoting to prevent unintentionally shooting when replacing arrows at the ready-to-shoot status of the crossbow. A resilient member is used to pull the transmission plate to move toward the second end of a case of the crossbow to deactivate the restriction to the positioning member such that the positioning member pivots and protrudes beyond a notch of the case to stop the shooting action of the string. After a new arrow is positioned, the safety member is moved again to drive the transmission plate from the second end to the first end of the case, and the activating member is released from restriction and the arrow is ready to shoot.

  • Patent number: 10209028
    Abstract: A crossbow having a string below the barrel and an arrow rest on top of the barrel. The carriage rides in a track along the length of the barrel. A bottom side of the carriage contacts the string. The upper side of the carriage extends through the upper edge of the barrel and contacts the nock at the aft end of the arrow. The string does not contact the barrel. The string, at about a midpoint, contacts the lower side of the carriage. The string does not rub on the barrel of the crossbow so energy loss and friction damage to the string are avoided.

  • Patent number: 10126088
    Abstract: 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.
