  • Patent number: 5394565
    Abstract: A portable play environment functions as a coat or jacket when worn and when not worn is capable of being used as a playing surface. It may include pockets or loops which act as storage means for carrying dolls, action figures, cars or similar small toys. Raised three-dimensional play objects may be permanently incorporated into the jacket. Expandable pocket structures have a dual function. When the jacket is worn by the child, the pocket structure functions as a ordinary pocket. The pocket structure may be removed, however, when the jacket is off and is being used as a play environment. When removed, it may be expanded into the general shape of a building or other imaginary structure. Flat cloth panels have graphic indicia printed on both sides. Such indicia typically will be in the form of maps or other small-scale representations of a natural or imaginary environment. Playing fields may be formed both on the back of the jacket and on its inner lining.
