Crossbow
A crossbow includes a frame, where the frame is provided with an arrow track for placing an arrow; the crossbow includes at least one limb; the limb includes a fixed end and a movable end; the movable end is moved toward the fixed end under pressure, such that two sections bent in opposite directions are formed on the limb to make the limb wave-shaped; the movable end is moved in a reverse direction to make the limb restored; and a primary string of the crossbow is directly or indirectly connected to the movable end of the limb. The limb of the crossbow can generate large elastic potential energy and can reduce the kinetic energy consumed by translation, and avoids the problem of different strokes between multiple limbs. The crossbow prevents the winding wheels from translating to consume the kinetic energy, such that the arrow can gain sufficient kinetic energy.
Projectile launching system
A device for launching a projectile along an intended flight trajectory includes a launching mechanism. The launching mechanism includes supports supporting a launching cord. A projectile having a longitudinal axis is disposed in the launching cord in a launch position prior to launch such that the projectile's longitudinal axis is perpendicular to a plane in which the launching cord is disposed. As the projectile is launched by the launching mechanism, the projectile rotates such that the projectile's longitudinal axis is parallel to the plane in which the launching cord was disposed.
Fletching jig and related method of use
A fletching jig can include constrictor ring that, when rotated, urges a plurality of arms supporting respective vanes toward an arrow supported in the jig to fletch the arrow. The arms can extend away from a base, which can support the arrow along a central axis. The actuator ring can be disposed around the arms. The actuator ring can include a ramp that can engage multiple guide blocks adjacent the actuator ring, each guide block configured to push a respective arm toward the arrow as the ring rotates. A related method of use is provided.
Three-in-one toy projectile launching assembly
An assembly for launching toy projectiles includes a body having a bore, a plunger extendable from the bore, and a shaft removably attachable to the body.
