Dynamoelectric shoes
First Claim
1. A dynamoelectric shoe, comprising:
- a shoe sole confining a watertight compartment;
a pressure-operated electric generator means provided inside said watertight compartment adjacent to a heel portion of said shoe sole, said electric generator means producing a voltage signal when pressure is repeatedly applied on said shoe sole during use; and
a power outlet means including an electrical socket mounted on said shoe sole and a rechargeable battery cell means wired to said electrical socket and to said electric generator means, said rechargeable battery cell means being charged by said voltage signal from said electric generator means, wherein said rechargeable battery cell means comprises;
a rechargeable battery cell connected to said electrical socket;
a battery charger circuit means receiving said voltage signal from said electric generator means so as to charge said rechargeable battery cell,a charging control means including means for deactivating said battery charger circuit means so as to stop charging of said rechargeable battery cell when the voltage across said battery cell exceeds a predetermined limit; and
a supplementary current supplying circuit means for providing additional current to said electrical socket when a plug is inserted into said electrical socket.

Abstract
A dynamoelectric shoe has a shoe sole that confines a watertight compartment. A pressure-operated electric generator is provided inside the watertight compartment adjacent to a heel portion of the shoe sole. The electric generator produces a voltage signal when pressure is repeatedly applied on the shoe sole during use. An electrical socket is mounted on the shoe sole and a rechargeable battery cell is wired to the electrical socket and is charged by the voltage signal from the electric generator means. The dynamoelectric shoe can be used to operate a portable wireless telephone, a portable radio, a light device to aid the user at night, or a heating device to warm the user'"'"'s foot during winter.
