  • Patent number: 4954676
    Abstract: An electrically heated soft toy for transmitting warmth to a person hugging the toy includes an outer casing filled with a soft stuffing material enclosing a battery powered electrically heated heat storage mass disposed in a cavity in the stuffing material and surrounded by a resiliently flexible mass of fibrous heat transfer material, such as a mass of tangled copper wires, having a greater thermal conductivity than the stuffing material. The stuffing material surrounds the fibrous heat transfer material except for a portion of the fibrous material which is in direct engagement with a selected portion of the outer casing so that heat is concentrated at a specific region on the exterior surface of the soft toy, which region may be reinforced by a flexible panel of durable wear resistant material, thereby making the transfer of heat to the person using the toy more effective.
