Claims
- 1. A footwear structure including a composite heating device particularly for ski boots, footwear structure comprising uppers defining portions and sole defining portions, said uppers defining portions comprising a shell and at least a rear quarter connected thereto, the composite heating device comprising electrically powered heating means at least in part arranged in said sole defining portions and electrical energy source means received in a seat formation in said footwear structure and circuit means electrically connecting said electrical energy source means and said electrically powered heating means, wherein said composite heating device further comprises a self contained receptacle member enclosing therein said electrical energy source means and having outwardly exposed electrical terminal means at one surface portion thereof, said seat formation having mating electrical terminal means contained therein and removably connectable with said outwardly exposed electrical terminal means, said mating terminal means being a component part of said circuit means electrically connecting said electrical energy source means and said electrically powered heating means, wherein said sole defining portions comprise an outsole integral with said shell and an insole, said self contained receptacle member further having attachment means for removable attachment with mating attachment means provided in said seat formation, said electrically powered heating means being incorporated within said insole, and wherein said seat formation is in the form of a casing formation integral with said rear quarter and is formed on the rear surface thereof substantially like a hollow parallelepiped body portion having a lateral opening for the insertion therein of said self contained receptacle member.
- 2. A footwear structure including a composite heating device particularly for ski boots, the footwear structure comprising uppers defining portions and sole defining portions, said uppers defining portions comprising a shell and at least a rear quarter connected thereto, the composite heating device comprising electrically powered heating means at least in part arranged in said sole defining portions and electrical energy source means received in a seat formation in said footwear structure and circuit means electrically connecting said electrical energy source means and said electrically powered heating means, wherein said composite heating device further comprises a self contained receptacle member enclosing therein said electrical energy source means and having outwardly exposed electrical terminal means at one surface portion thereof, said seat formation having mating electrical terminal means contained therein and removably connectable with said outwardly exposed electrical terminal means, said mating terminal means being a component part of said circuit means electrically connecting said electrical energy source means and said electrically powered heating means, wherein said sole defining portions comprise an outsole integral with said shell and an insole, said self contained receptacle member further having attachment means for removable attachment with mating attachment means provided in said seat formation, said electrically powered heating means being incorporated within said insole, and wherein said seat formation is in the form of a recess provided on the inner surface of said rear quarter, the open said of said recess facing inwardly for inserting therein from the inside said self contained receptacle member.
- 3. A footwear structure according to claim 2, wherein said attachment mean comprise a projection on a first surface of said self contained receptacle member, said first surface engaging said inner surface of said rear quarter, and said mating attachment means comprise a through opening in said rear quarter extending through a rear wall portion of said rear quarter from an inner to an outside surface thereof to engageably receive therein said projection when said self contained receptacle member is arranged within said recess with said first surface thereof engaging said inner surface of said rear quarter, thereby to render said projection accessible from the outside for the ejection of said self contained receptacle member from said recess when said projection is pushed inwardly from the outside with the rear quarter in an opened position.
- 4. A footwear structure according to claim 3, wherein said projection is in the form of a button pivotally supported on said first surface of said self contained receptacle member about an axis perpendicular thereto and excentric with respect to a center of said button to allow self locking of said self contained receptacle member in position within said recess.
- 5. A footwear structure according to claim 4, wherein said circuit means include a switch having a switch actuation member projection from said outside surface of said quarter proximate to said button.
- 6. A footwear structure according to claim 4, wherein said circuit means include a potentiometer and switch circuitry having a potentiometer actuation member projecting from the outside surface of said quarter proximate said button and further include a control light on said outer surface for indicating the operating status of the heating device.
- 7. A footwear structure according to claim 2, wherein said self contained receptacle member is a first receptacle member and wherein said circuit means are contained in a second receptacle member permanently fixed in said recess formation and providing abutment surface for positioning and locking said first receptacle member.
