  • Patent number: 6377780
    Abstract: A device suitable for use as a child's toy includes a housing having a window through which is visible a medium on which are displayed changing scenes. A plurality of lights are positioned behind the medium and selectively illuminated to provide animation effects. Different portions of the medium may be selectively illuminated as the scenes are changed in order to vary the animation effects. The medium may be in the form of an at least partially translucent scroll, on which is printed a series of different scenes and which may be moved by a motor, spring, or other winding mechanism arranged to advance the scroll so that a different complete scene appears in the window each time the scroll is advanced.

  • Patent number: 6332822
    Abstract: A diving stick of the type which, after being tossed into a swimming pool, sinks to the bottom while maintaining an upright posture so that it can easily be grasped by a diver, includes a soft malleable outer body designed to prevent accidental impalement, and provisions for enabling the diving stick to sink and maintain an upright posture at the bottom of the pool despite the buoyancy of the soft malleable material.

  • Patent number: 6280277
    Abstract: A toy includes a main body which, in a first orientation, resembles a water gun and, in a second orientation, resembles a vehicle. Within the main body is an air/water reservoir which may be filled with water, the reservoir being in communication with a source of air pressured by a hand-pump to cause water to be forcibly expelled from the reservoir upon opening a valve at a water outlet of the reservoir. The water outlet is controlled by a trigger mechanism which, when the toy is in the first orientation, resembles the trigger of a gun and permits opening and closing ofthe valve to occur upon pulling and release of the trigger. In the second orientation, the trigger mechanism is latched upon pulling the trigger in order to permit continued expulsion of water upon release of the trigger so that the expulsion of water serves to propel the vehicle.

  • Patent number: 4863545
    Abstract: The present invention relates to a method of attaching a flexible plastic component to a rigid plastic component. The present technique can be used for such purposes as retrofitting suction cups to rigid plastic hollow legs such as may be provided to a children's bathtub seat. The flexible plastic component is attached to the rigid plastic component by use of the following procedure: (a) a passage is provided in the rigid component; (b) an extension is contoured to slidably engage the passage in the rigid plastic; (c) the extension is provided with one or more indentations; (d) the rigid plastic inserts are contoured to fit the indentation in the extensions; (e) the inserts are placed in the indentations; (f) the rigid plastic inserts are wet with a bonding liquid; (g) and finally the extension is inserted into the passage in the rigid plastic.

  • Patent number: 4522604
    Abstract: A rockable toy with a reflecting mirror includes a body having a bottom surface which is outwardly curved in all directions, and a center of gravity which is situated within the region bounded by the bottom wall, so that the toy will have a tendency to oscillate about a stable position in which the center of gravity is situated above the point of contact of the toy with the underlying surface. The body carries a mirror which shares in the oscillatory movement of the body when displaced out of the stable position. The body carries, outside the periphery of the mirror, a head whose reflection can be seen in the mirror by the observer, together with a background which rapidly changes during the oscillatory motion of the toy. The head is connected to the body for movement relative thereto at least in two opposite directions. The body is of a rigid synthetic plastic material, while the head is of a flexible material so that it can be squeezed.

  • Patent number: 4353701
    Abstract: An educational, action-type amusement center toy for children comprises a set of three pop-up members mounted on a housing, each pop-up member being movable from a hidden position to a display position. Each pop-up member is actuated by a different plurality of actuators in response to different manual actions performed by the child.

  • Patent number: 4335538
    Abstract: An air-inflatable overhead crib gym toy encourages children to perform exercise-type manual movements with safety. The toy has an inflatable elongated tubular body in which a movable toy object is received, a pair of longitudinally-extending inflatable tubular extensions at opposite ends of the body, and a transversely-extending inflatable tubular projection which extends downwardly towards the child. A handle is swingingly supported from each extension. The movable object is visible through transparent side walls in the body, and is movable when the child grasps the handles, the projection, or any other part of the toy. Noisemakers are actuated when the child manipulates the toy. The inflated toy is soft and yieldable to the touch to protect the child from injury, and restores itself to its inflated condition when the child releases the toy from his grasp.

  • Patent number: 4272911
    Abstract: A toy having a transparent hollow outer shell is formed in the shape of a surface of revolution with an axis of symmetry and contains an object visible through said shell. The object is clear of the inner surface of the shell. A flexible elastic band having spaced points of connection to the shell and located on said axis of symmetry is fixed to and supports the object between said connection points. The object's center of gravity is below said band. Rolling of the shell about its axis twists the band as the center of gravity of the object remains below the band. When the band has stored up enough energy, it untwists and spins the object first in one direction and then reversely.

  • Patent number: 4232477
    Abstract: An inflatable toy which when inflated has the contour of a hassock. The toy features a cylindrical envelope and inner radially-extending planar baffles, these elements being composed of soft limp flexible material such as a thermoplastic plastic. When the toy is inflated by introducing air under mild pressure into the envelope, the top and bottom walls of the envelope are distended so as to assume the contour of the top and bottom of a hassock, i.e. with a central bulge and discrete radial outward bulges. This configuration is formed by disposing the baffles vertically and mutually angularly spaced, each of the baffles extending radially from near the central axis of the envelope and terminating short of the periphery of the envelope, with rectilinear attachments of the top and bottom edges of each of the baffles to the top and bottom walls of the envelope. The baffles are tautened by outward force exerted on the top and bottom walls between the baffles, by the pressure of the inflating air.

  • Patent number: 4223471
    Abstract: An amusement device for infants, babies and small children, especially intended to be mounted to a side wall of a crib. The device includes a transparent enclosure which in practice is filled with a liquid, and which contains at least one movable object such as a sphere or a simulation of a fish. The density of the object or objects is greater than the density of the liquid. A flexible resilient bellows extends from the lower end of the enclosure and a liquid transmission pipe or nozzle extends between the enclosure and the bellows. The bellows may be manually expanded by the infant or child, so that a body of the liquid is drawn from the enclosure into the bellows. A spring extends from the bellows to a lower fixed mounting, so that when the bellows is manually expanded, the spring is compressed against the lower fixed mounting and urges the bellows to an idle contracted shape, so that liquid is expelled from the bellows into the enclosure when the child releases the bellows expansion element.

  • Patent number: 4223474
    Abstract: An inflatable nursery toy typically consisting of a large generally barrel-shaped inflatable outer bag composed of soft, limp, flexible and non-resilient sheet material such as plastic, with donut-shaped cuffs at either end thereof. A smaller, separately inflatable cylindrical tube, usually composed of the same plastic material as the outer tube, is located within the barrel and is inclined lengthwise of the barrel relative to the axis of symmetry thereof. A plurality of balls are located within the cylindrical tube, and these balls travel lengthwise due to gravity, as a child rolls the barrel along the floor.
