Abstract

Footwear that has a generator that generates electricity from the walking action of the wearer, the electricity is then converted into heat. Preferably the generator is located in the heel of the footwear. The heel may be divided into two layers, a magnet 6 is attached to the uppermost layer of the heel 3 and a coil of copper 5 is attached to the lowermost layer 4. The compression of the two layers as the heel hits the ground causes the relative movement of the coil and magnet towards each other and vice versa then the heel is raised from the ground thereby generating electricity. The electricity is delivered to high resistance wires 7 in the rest of the shoe that produces heat.

Description

Heat generating shoes This invention relates to heat generating shoes Cold

feet are a nuisance and can be life and limb threatening and lead to frost-bite. Means already exist to warm shoes by an external electricity supply or battery but this invention relates to the generation of electricity and heat from the action of walking.

According to the present invention there is provided a pair of shoes, the heel of which is divided into two layers the bottom layer inflexible and uppermost flexible linked by a small generator, the movement of heel stepping compressing the two heel layers causing relative movement between the magnet and copper wire (and also during heel rising) and thereby producing electricity which passes beneath the rest of the shoe in high resistance wires therefore generating heat.

The invention will now be described by way of example with reference to the following drawings: Fig I shows the heel of the shoe separated into two layers with a generator between them radiating from it high resistance wires.

Fig 2 shows movement of the upper and lower heel towards (or away from) each other during walking with relative movement between the wire and magnet.

Referring to figure 1 the generator sits between the two layers of the heel with the magnet 6 attached to the uppermost layer of the heel 3 and the coil of copper 5 on the lowermost layer 4. The heel then unites towards the front of the shoe 2.

Referring to fig 2 relative movement of the coil and magnet towards 9 (during heel contact with ground 8) or away from (during heel rising from the ground) each other generates electricity which is then delivered by high resistance wires 7 to the rest of the shoe I and is converted into heat.

Claims (1)

1. Heat generating shoes Claims 1 A pair of heat generating shoes, each one

   comprised of an adapted heel that divides into two parts at the rear, the upper segment being relatively fixed and flush with the sole, the lower part being flexible, (or vice versa), a coil and magnet (generator or solenoid) inserted on the upper and lower heel respectively and allowed to interact with one another. The action of walking and heel strike causing compression of the heel parts and relative movement of the magnet against the coil (and alternately with relaxation of the heel) with energy converted to electricity and diverted along high resistance wires that spread within the shoe. The electricity is then converted to heat energy with the ability to warm and dry the shoes whilst walking whatever the conditions and furthermore do not need recharging or drying.
