  • Patent number: 9933219
    Abstract: Crossbows having two trigger safety locks. Operatively connected to a trigger is a trigger lock element that in one position prevents the trigger from moving. To prevent inadvertent contact between a cocking slide and a released stretched cord of the crossbow, a slide lock element engages the trigger lock element until the slide lock element is disengaged by the cocking slide moving out of the way. To prevent an improperly configured projectile from being discharged a projectile lock element engages the trigger lock element until a properly configured projectile is loaded onto a drum causing the projectile lock element to disengage from the trigger lock element.

  • Patent number: 9513075
    Abstract: Several embodiments of toy dart launch apparatus are disclosed including two crossbows with stretchable cords, a spring driven apparatus and an apparatus with battery operated rotatable wheels. Each apparatus includes an open top drum for receiving and storing darts. The darts are tubular and formed of soft foam. The drum includes an open outer surface with spaced recesses so that loaded darts are exposed, the darts being received by a spike in each recess. The recesses also include protrusions for restraining the stored darts on the spike, and a platform is mounted in the crossbows to support each dart when the released stretched cord impacts the dart. In the case of a rotating wheel arrangement, there is no need for spikes on drum or a platform.
