A nock for an archery arrow or bolt. The nock includes a radial indention configured to be engaged by a biased retainer of a trigger mechanism of a crossbow to retain the arrow or bolt in a desired position relative to the trigger mechanism and/or a bowstring. The radial indention may optionally comprise a groove defined generally continuously around a circumference of the nock. The radial indention is exposed when the nock is coupled with an arrow or bolt such that the radial indention may be engaged by a biased retainer within the trigger mechanism. The nock may further include a generally planar rearward bearing surface configured for being engaged by a bowstring. The nock of the present invention may be suitable for use with a multiple-shot crossbow or a single-shot crossbow. Other aspects of the present invention are directed to a projectile, a projectile retention system, and a crossbow.

A double crossbow with a single trigger mechanism is provided. The double crossbow comprises a barrel, an upper bow, a lower bow, and a single trigger mechanism. The upper bow and the lower bow are positioned on top of each other at a distal end of the barrel. The single trigger mechanism positioned at a proximal end of the barrel is configured to shoot two arrows in succession without reloading an arrow between two shots. A first arrow is shot from the upper bow when a single trigger of the single trigger mechanism is squeezed completely a first time, and the second arrow is shot from the lower bow when the single trigger of the single trigger mechanism is squeezed completely a second time. The single trigger mechanism is configured to not shoot the first arrow and the second arrow simultaneously.

A crossbow including at least one trigger assembly that may have a string catch, a sear, a trigger actuator, and an anti-dry-fire mechanism. The anti-dry-fire mechanism can include (i) a bolt sensor movable between a bolt-absent position and a bolt-present position, and (ii) a linearly reciprocating sear latch movable between a latched position and an unlatched position and biased toward the latched position. The bolt sensor may be pivotably coupled to the sear latch so that (i) with the bolt sensor in the bolt-absent position, the sear latch is held in the latched position by bias force thereon, and (ii) with the bolt sensor held in the bolt-present position, the sear latch is held in the unlatched position against the bias force thereon. When in the latched position, the sear latch can prevent movement of the sear.

The Double crossbow (the double bow) in the field of Mechanical engineering.

The Double crossbow addresses the need to fire multiple arrows at targets without having to reload.

The Double Crossbow is a hand held bow that can fire two arrows without reloading, from two separate bows where both arrows are held in place before firing by a spring and the string of each bow is held by two pawls in the trigger unit and released by the triggers after the automatic safety catch is removed. The aiming of the crossbow can be done by telescopic or open sights (optional) mounted on adjustable rails and where accessories can be fitted to the crossbow. It can be made of any or a combination of wood, metals, plastic, composite and fibreglass materials as deemed suitable and a variety of finishes will be applied to suit crossbow use and marketing design requirements. The principle use of the invention is for target shooting and animal hunting.

A crossbow, which enables the firer to fire two arrows onto a target without having to reload between shots, using telescopic or iron (open) sights and capable of taking multiple accessories.

A multi-shot crossbow includes a crossbow arm, bowstrings, and a crossbow body, wherein the crossbow arm is provided with a slider which is slidably connected with the crossbow arm along a longitudinal direction of the crossbow arm, a top of the crossbow arm is fixed with an arrow chamber which is provided with a plurality of longitudinally extending arrow holes, each of the arrow holes is provided with a slidably connected hammer, each hammer is fixedly connected to the slider, the bowstrings are located below the crossbow arm, and when the slider is at a back end point, the slider is movably attached to the crossbow body. Multiple arrows can be simultaneously shot, and the hammers can be arranged side by side and can shoot all the arrows at the same time. All the arrows are evenly driven and are shot with small radius and high hit accuracy.

A multiple-shot crossbow includes a mainframe, a riser, upper and lower bow limbs and bowstrings, and a trigger mechanism. The mainframe includes upper and lower rails, each for supporting and guiding a corresponding bolt. The riser includes a passage for accommodating loading and launching a bolt. The bow limbs are attached to the riser and the bowstrings are attached to the bow limbs. Each bowstring is arranged independently to be drawn from a brace position to a drawn position and then return to the brace position while launching a bolt positioned on the corresponding rail. The lower bowstring is movable within a longitudinal slot between the upper and lower rails. The trigger mechanism is attached to a rear end of the mainframe and includes upper and lower trigger portions, each retaining a corresponding drawn bowstring and then releasing it upon actuation by a user.

A crossbow includes a barrel, a cocking device, a bow device, a link device and a cartridge. The retention member is moved by the operation of the string of the bow device. The cocking device detachably holds the string. By repeatedly operating the link device and pulling the trigger, the cocking device is moved back and forth repeatedly, and the retention member moves back and forth to control the restriction member to pivot so that the bullets continuously drop to the groove and located in front of the retention member. Therefore, the crossbow can shoot the bullets continuously. The bullets are allowed to be fed into the cartridge one time of feeding.

A magazine for storing and separating projectiles for a weapon, in particular for a bow weapon, includes a storage section, which is configured to house at least partially cylindrical projectiles, in particular arrows or bolts, and extends in a first direction. The magazine includes a separating mechanism coupled to the storage section. The separating mechanism includes an actuation section configured to be actuated by the movement of at least one actuation mechanism of a weapon when moved with respect to the first direction. The separating mechanism, upon actuation of the actuation section, is configured to separate a single projectile from a plurality of projectiles in the storage section. The separating mechanism includes a holding section configured to hold the separated single projectile with a predefined force in a launching area of a weapon. A weapon including such a magazine and a method for manufacturing such a magazine are also described.

An arrow supply assembly for a bow includes an operation box connected to riser of a bow, and a cartridge is connected to the operation box. The operation box includes a first passage defined axially through two sides thereof, and a string of the bow movably extends through the first passage. The cartridge includes a second passage communicating with the first passage. The second passage includes an insertion path and an entrance. The insertion path accepts multiple arrows to be stored in the cartridge. A press member is pivotably connected to the cartridge and biased by a resilient member so as to press and supply the arrows in the cartridge into the first passage. The users pull the string continuously to shoot the arrows that are fed into the first passage of the operation box.
