  • Patent number: 6022263
    Abstract: A toy figure includes a lower torso, an upper torso rotatably attached to the lower torso, and a head and two arms each rotatably attached to the upper torso. A spring connected with the lower torso and the upper torso rotates the upper torso from a second to a first position with respect to the lower torso. A friction clutch retards rotation of the upper torso about the lower torso. A drive gear is connected with the lower torso. Two driven gears are engaged with the drive gear and mounted to a separate arm shaft of the arms. The driven gears roll around the drive gear and rotate the arms in opposite directions when the upper torso rotates about the lower torso. Upper and lower arm sections can be fixed together or hinged. Where hinged, a linkage between the lower arm and upper torso rotates each lower arm section about an upper arm section as the arm rotates about the upper torso.

  • Patent number: 5924910
    Abstract: A toy vehicle includes a chassis and a pair of shell halves rotatably attached to the chassis, which in a first position form a vehicle body that bounds an interior space. A four-bar linkage is attached to the chassis and is disposed at least partially within the interior space. A pair of external finger tabs is pivotally attached to the chassis and connected with the linkage by means of pinion gears and a rack. Movement of the finger tabs together drives the linkage to raise and project a simulated weapon on the linkage and releases the shell halves to separate. Reverse movement of the tabs reverses the operation. A second toy vehicle includes a chassis and a pair of rotatable body panels and a different four-bar mechanism attached to the chassis beneath the body panels in a first position. A pair of external finger tabs is pivotally attached to the chassis.

  • Patent number: 5622159
    Abstract: A toy weapon firing a shapeless solid charge includes a reciprocating air pump and an extruder including a reservoir of the shapeless flowable solid material. A tubular nozzle member is mounted on the outlet end of the air pump and includes a transversely extending nipple providing a fluid coupling with the outlet of the extruder. A portion of the housing is configured to form a hand grip while a separate hand grip is coupled with the air pump piston to permit reciprocation of the air pump piston by reciprocating the hand grip portions towards one another and away from one another. The extruder may be operated separately from the air pump or linked with the air pump for simultaneous operation to feed a charge of the shapeless, flowable solid material into the nozzle member before or while the air pump is reciprocated.

  • Patent number: 5598950
    Abstract: A water toy that ejects a stream of water under pressure and in one embodiment is particularly suited to serve as a water-sword toy and in another embodiment to serve as a pump-action water gun toy is disclosed. In both embodiments, the water toy includes a wide mouth reservoir that accepts ordinarily available ice cubes which cooperate with water so that chilled water is emitted, under pressure, which may have some soothing benefits, especially during hot summer conditions. The water-sword toy not only emits water upon contact of its tip by an object, but also has provisions for emitting water out of its tip without contacting any object. The pump-action water gun toy has provisions to provide for a straight or spread water trajectory so as to simulate a rifle-water toy or a shotgun-water toy.

  • Patent number: 5538456
    Abstract: A water toy has the shape of an aerial bomb or rocket with generally bulbous, resiliently flexible body and a removable tail member with fins, The water toy includes a resilient shell having a mouth and an internal pointed member facing the mouth. A balloon has a mouth with a lip that fits around and engages the mouth of the shell with the balloon body in the shell. The two mouths are sufficiently large to receive ice cubes. A cover member is fitted over and releasably engages the mouth of the shell sufficiently snugly to seal the mouth of the balloon on the mouth of the shell. The cover member has a recess with a one-way check valve to permit the balloon, which is sealed between the cover member and shell, to be filled with water. The tail member is received in the recess and releasably engages the cover member. Dispersion passageways extend from the inner through the outer surfaces of the shell.
