  • Patent number: 9958230
    Abstract: A rapid fire toy dart launch apparatus employing a feeding/anti-jamming mechanism including a simply yet unique continuous belt that penetrates a dart magazine releasing each dart from the magazine and simultaneously employing protrusion elements at the belt advancing each released dart into an energy generating mechanism for rapidly firing darts from the toy apparatus without mis-fed darts jamming up in the launcher.

  • 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.

  • Patent number: 7354352
    Abstract: A swing apparatus comprises a support stand, a swing supported with respect to the support stand to oscillate back and forth along a swing arc about a pivot axis, and a drive assembly that operates to oscillate the swing. Various components of the drive assembly are coupled to the swing to oscillate therewith about the pivot axis. The drive assembly has a pair of drive members that periodically engage portions of the support stand resulting in forces being imparted on the swing to move the swing.

  • Patent number: 4638999
    Abstract: A balancing clip for a rectangular tilting game board with a central pair of axes coinciding with edges of projections which support the board above the underlying surface. The board is elevated to allow its tilting in either direction when the playing pieces thereon are unevenly distributed to cause a predetermined moment on one side or the other. The axes are located equal distances from the board's transverse centerline and are at the same level. The center of gravity of the combined board and playing pieces in their starting position and the axes are approximately at the same level. The longer sides of the board having depending edges or flanges with beads along their bottoms. The balancing clip has a resilient U-shaped part which resiliently grasps the flange on which it is received above the bead and is slidable along the flange to the position required to achieve the board's proper balance. The clip includes a weight part which extends normally relative to the flange under the board.
