Shoe with foot warmer including an electrical generator
First Claim
1. In a foot warmer mechanism for a shoe having a heel with an open compartment and an outer sole and having an inner sole mounted within said shoe for relative vertical movement therein and with a mechanical translator located in said open compartment of said heel and mechanically linked to the reciprocal vertical movement of said inner sole and electrical generation means seated in said compartment within said heel and including a gearbox and a mechanically interconnected electrical generator and electrical heating means within said shoe in circuit to said electrical generator, the improvement comprising:
- .a. a flywheel mounted for rotational movement on a vertical axis in the heel of said shoe and mechanically coupled through said gearbox to said electrical generation means;
b. a sleeve coupled to said mechanical transducer also mounted in the heel of said shoe coaxial with said flywheel; and
c. a resilient helical coil spring with its inner end secured to said sleeve and its outer end secured to said flywheel,whereby rotational movement of said sleeve is resiliently transmitted to said flywheel, and said spring absorbs the shock from impacts applied to said sleeve by rapid and forceful movements of said inner sole.

Abstract
There is disclosed an inner shoe for a molded ski boot which includes a foot warmer mechanism having an electrical resistance heater, an electrical generator, a mechanical translator to translate vertical movements of the wearer'"'"'s heel into uni-directional rotational movement of a flywheel, and a gear box mechanically coupling the flywheel to the electrical generator. Specific features of the mechanism include: a shock absorbing resilient coupling of the flywheel to prevent damaging the mechanism while juming or otherwise subjecting the shoe to hard usage; interchangeable generators and gear boxes to accommodate wearer'"'"'s of varied size and weight as well as for varied intensity of activity; and an entirely sealed, remote latch to lock the mechanical drive out of operation.

13. In a ski boot of the construction having an outer molded plastic shell and an inner shoe lining and a molded inner shoe having an upper portion with an integral sole and a contour conforming to the inner shape of said shell, the improvement comprising:
-
a lower sole coextensive with said integral sole of said inner shoe and pivotally secured thereto at the toe of said shoe, and having at least a first open-topped compartment of a size and shape to fit within the heel area of said outer shell; at least a second open-topped compartment which fits within the instep area of said outer shell; and electrical generation means including a gearbox and a mechanically interconnected electrical generator removably seated in said first open-top compartment within said heel area and a resilient spring mounted within said second compartment within said instep area of said shoe, beneath said inner sole to bias said inner sole upwardly against the foot of the wearer of the shoe. - View Dependent Claims (14, 15, 16, 17, 18, 19)
