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.
