A dart pistol utilizes an assembly of a pistol body, a launch channel, a carriage, a mainspring, an operating bar, an engagement feature, a trigger member, and a retainer pin to adapt a conventional game of throwing darts into a shooting sport. The launch channel is formed into the pistol body such that the carriage, mainspring, and operating bar are slidably mounted between a fore body end and a rear body end. The mainspring is connected between the carriage and the fore body end to impart a launching force to at least one projectile via the carriage. The retainer pin is laterally mounted into the channel to capture the engagement feature of the operating bar until dislodged by the trigger member. The trigger member is pivotably mounted to the pistol body, operatively coupling the trigger member to the operating bar to fire the dart pistol.

A firing system for a crossbow having an arrow rest extending along an arrow rest axis, the firing system having a right limb and a left limb, the right limb being pivotable about a right limb axis and the left limb being pivotable about a left limb axis, the firing system further including a right cam and a left cam, the right cam having a right bow string groove and being rotatable about a right cam axis, the left cam having a left bow string groove and being rotatable about a left cam axis, the firing system having a bow string extending between the right and left cams and extending within the right and left bow string grooves, the bow string positionable between an un-cocked condition and a cocked or full draw condition wherein movement of the bow string from the un-cocked condition toward the cocked condition moves the right and left cams toward each other and pivots the right and left limbs about the right and left limbs axes respectively, the firing system further including a power assembly having a power cable and a spring assembly, the power cable having a forward end operably joined to the right and left limbs and a rear end operably joined to the spring assembly, the spring assembly having a power spring extending along a power spring axis between a first spring end and a second spring end and having a central spring opening, the power spring being below the arrow rest, the power cable extending through the central spring opening from the first spring end toward the second spring end, the rear end of the power cable being operably joined relative to the second spring end of the power spring, moving the bow string from the un-cocked condition to the cocked condition causing the right and left limbs to the pull forward end of the power cable forwardly wherein the operable engagement with the second spring end compressing the power spring by pulling the second spring end toward the first spring end to produce the shooting force to propel the archery arrow.

The present invention discloses a color bar launcher, which comprises a cylinder for holding color bars and an elastic sleeve; Two ends of the cylinder are open, one end is connected with an end cover, and the other end is closed by the elastic sleeve; the middle part of the outer side of the elastic sleeve is provided with a hand pinching part; the surface of the end cover is provided with a launching port, a positioning ring is fixed around the launching port, protrusions are arranged inside the positioning ring, and a sealing sheet that closes the launching port is movably assembled between the positioning ring and the protrusions. It can ensure the successful launch of the color bar; at the same time, it has the advantages of simple structure, convenient assembly and low cost.

An elastic energy storage and deployment system deploys a torsional spring that bias a cam connected to a cable. The cam is coupled to the torsion spring about a shared rotational axis such that the cam directs elastic energy to and from the torsion spring and the cable transforms rotational force into linear motion, with little rotational inertia, and the addition of angular acceleration.

The invention relates to a magazine for receiving and accommodating one or more projectiles in a toy gun. The magazine comprises a housing defining a chamber adapted to accommodate the one or more projectiles in a longitudinal, inline arrangement; a first positioning member arranged at the chamber and being movable relative to the housing; wherein the first positioning member comprises one or more first engaging means adapted to engage the one or more projectiles, such that the one or more projectiles are permitted to move longitudinally along the chamber in one direction only in response to a projectile advancing or loading movement of the first positioning member. The invention also relates to a toy gun having the magazine as described.

A means is provided for defending a target from attack by a torpedo with high probability. When a controller detects a torpedo based on an image generated by a sonar, it specifies a path of movement of the torpedo. If there is a water craft or the like within the path of movement, the controller instructs a launcher to launch a torpedo capture device and instructs mines to switch to detonation-off mode. Moveable devices of the torpedo capture device launched by the launcher in accordance with the instruction of the controller move in the water to spread a net. The controller then specifies a location of each of a first moveable device and second moveable devices based on an image generated by the sonar, and instructs the first moveable device and the second moveable devices to move such that the center of the net is within the path of movement of the torpedo. The first moveable device and the second moveable devices move in accordance with the instruction of the controller. When the torpedo reaches the net, the net captures the torpedo and the mines, which are in the detonation-on mode, explode the torpedo before it reaches the water craft or the like.

A toy launcher for launching projectiles that includes a drum having a substantially circular shape and comprising a ring of projectile holders to hold projectiles for launching, the ring of projectile holders including a ring of inner support portions located substantially at a first radius from a center of the drum, each inner support portion adapted to support at least a portion of a projectile on an inner concentric ring of projectiles, and a ring of outer support portions located substantially at a second radius from the center of the drum, each outer support portion adapted to support at least a portion of a projectile on an outer concentric ring of projectiles, wherein the second radius is different than the first radius, and wherein the drum includes a ring of front openings and a ring of rear openings that are aligned with at least the inner concentric ring of projectiles.
