  • Patent number: 4774769
    Abstract: A device insertable into shoes is capable of drying, warming and disinfecting shoes. A perforated casing in the shape of a shoe interior holds an electric heater. The heater is powered by a power cord which extends from the casing. Arranged next to the heater is a receptacle for holding disinfectant. Heat from the heater evaporates the disinfectant, which is spread throughout the shoe through the perforations. A telescoping heel section ensures that the disinfectant will reach all sections of the shoe. A clip hingedly attached to the casing permits easy insertion and removal of the device from the shoe.

  • Patent number: 4517443
    Abstract: The apparatus for heating and drying shoes not only has a stretching member with an electrical resistance heater, but also a clip, which is fixed in an articulated manner to the stretching member. Thus, the apparatus is used not only for heating and/or drying, but simultaneously for maintaining the shape of the shoe in which it is placed. Advantageously, the joint between the clip and the stretching member is a snap connection, which is secured against detachment by the electrical resistance heater. For this purpose, the pivoting connection can be provided on the stretching member with a resilient cover plate, which engages on the clip and carries a projection braced on the electrical resistance heater. The slot in the clip for the passage of the cable can also be provided with a slef-locking element, which prevents a relative movement between the cable and clip if the cable is pulled away from the shoe apparatus.
