  • Patent number: 5213504
    Abstract: A liquid non-poisonous, non-metallic, edible, water soluble coloring fluid fills a felt-tipped marker. A plastic box houses the marker or a plurality of the markers. A surface on the box receives the marks from the felt-tipped marker. In one embodiment, the box is in the form of a toy vehicle. In other embodiments, there may be a plurality of stencils which can be arranged in a scene or a scroll which may be rolled to display a selected scene. Then a tracing of the scene may be made on an overlaying sheet of transparent plastic. An eraser in the form of a sponge with a plastic handle may be made wet to wash away the marks.

  • Patent number: 5190298
    Abstract: Memory-oriented or pattern matching games use game pieces having indicia which become excited responsive to a brief exposure to strong light or another activating event for emitting colored light during a short period of time. The games use the excitable indicating medium to present certain information to the players for a short time period. Thereafter, the players are required to use their memory of the temporarily-presented information in order to accomplish some task. In some embodiments, the games present a random arrangement of color-coding which soon becomes invisible after the excitement subsides. Then, the players must use their memory of the game piece locations to select only those pieces which are assigned to them. In another embodiment of the invention, a maze is printed in excitable ink which is visible only during the short time period of excitement. The players must try to complete the maze before the pattern, or their memory of it, dissipates.

  • Patent number: 5163846
    Abstract: A toy has a frame with a display area for receiving a water reactive paper. The paper has a brightly colored substrate covered by a surface layer of silica and resin which becomes transparent when wet and opaque when dry so that the bright color does or does not show through depending upon whether the surface is wet or dry. Thus, the paper appears to have disappearing ink.

  • Patent number: 5028047
    Abstract: A game apparatus has a housing and a removable lid for covering the housing. A brief flash of high-intensity illumination is provided when the lid is removed. A number of playing pieces randomly positioned within the housing receive the illumination of the flash. The playing pieces briefly radiate color-coded visible light after receiving the flash, forming a random pattern of colored light. At least two players may view the game pieces to form impressions of the locations of the playing pieces while they are radiating the light. Each player must rely upon his memory as to where his color of playing pieces are located. The players use an implement to remove the game pieces in turn according to his memory of where colors assigned to him are located.

  • Patent number: 5006089
    Abstract: A stuffed animal has a closed fluid containing liner filled with a viscous silicon or silicon/water material. The weight of the silicon/water material gives the animal a life-like weight. The liner is covered by a fur-like plush. The viscous material may be a material used to make a prosthesis of a human organ. If desired a material such as a plastic simulation of a skeleton may be added to give a feel of bone. The "skeleton" may have a plastic memory for causing the animal to retract its leg, paw, or the like after it has been stretched. Small patches of hook and loop fasteners may be used to secure the animal in a desired posture.

  • Patent number: 4575355
    Abstract: A toy vehicle has a seat with a simulated seat belt in the form of two semi-circular parts which are able to rotate between an opened and closed position, the closed position simulating fastened seat belts. A power release push button is centrally positioned on the vehicle so that it does not exert any unbalanced force on the vehicle when it is pressed. When the seat belt is opened, the push button is captured in a raised position so that the vehicle cannot run. When the seat belt is closed, the capture is released from the push button so that is can be pushed. Thereafter, the push button is pushed, the power is released, and the toy vehicle is propelled.

  • Patent number: 4547174
    Abstract: An inertia motor especially--but not exclusively--for a toy vehicle. A rear wheel axle extends through the housing and has a drive gear mounted thereon to turn unitarily therewith. A flywheel is rotatably mounted on the housing for spinning to store or to payout energy. First and second gear trains extend between the drive gear and flywheel. A movable control lever carries first and second movable gears, one of the movable gears being an idler mounted on and movable with a shaft which passes through a pair of oppositely disposed arcuate slots, the other movable gears being mounted on a shaft journaled in the lever arm. The arcuate slots are located so that the idler gear meshes with one of the gear trains when the lever arm is in one of its two positions.

  • Patent number: 4541815
    Abstract: A toy vehicle has a gear box containing a clock spring which is wound by pushing the vehicle backward. A two part toggle-linkage system connects the gear box to the frame. When the clock spring is wound, the resulting spring bias urges the toggle-linkage system to one over center position which locks the gear box in order to preserve the energy stored in the wound spring. When the toggle-linkage system is pressed near its center, it moves over center to another position, which unlocks the gear box and releases the energy stored in the wound spring in order to propel the vehicle. When the vehicle is next moved backward, the toggle-linkage returns to the locked position which once again locks the gear box.
