Definitions

  • This invention relates generally to thermally insulative coverings, m itts and the l ike for ski boots.
  • U.S. Pat. No. 20080295357 A1 ( Long) discloses a n insulating footwear cover which has an upper, and a wea r-resistant sole portion extending beneath the bottom of the boot or shoe. The sole portion additional ly overlaps a portion of the sides of the upper providing a wear-resistant patch over areas of the cover that are most susceptible to wear.
  • U.S. Pat. No. 5893220 (M il ler) provides a thermal ski boot cover made of elastomeric fabric, which covers primarily the toe portion of the b oot, with the fabric ends of wrapped around the back of the foot and secured using releasable attaching means such as hook and loop fasteners.
  • a bottom strip is present, which is sewn to each side of the boot cover and extends under the ski boot to hold th e cover in place.
  • the present invention seeks to provide a thermally insulative ski boot covering, which will overcome or substantial ly amel iorate at least some of the deficiencies of the prior art, or to at least provide an alternative.
  • thermally insulative ski boot covering com prising a body of unitary construction having an integra lly formed vam p, toe box, longitudinal arch ladder, quarter and openable heel counter.
  • the longitudinal arch ladder is con nected between medial and lateral rear edges of the toe box, thereby exposing a ball void through which a toe binding and bal l of a ski boot is exposed.
  • the vam p term inates at the quarter and the quarter has surface fastener s thereon. The quarter does not extend past an imaginary calf l ine.
  • the heel counter has a longer length than that of the quarter, so as to thereby be able to extend around the calf l ine and has heel counter surface fasteners thereon for attachmen t to the quarter surface fasteners, thereby encircling a heel void through which a heel and heel bindings of the ski boot are exposed.
  • the vam p overlays a throat line to form a top line with the heel counter.
  • the quarter locates lateral ly and ha s the surface fasteners on an in ner surface thereof which overlays the heel counter surface fasteners of the distal end of the heel counter extending thereunderneath .
  • M iller for exam ple, the primary design consideration of M iller is for weather shielding whereas the present invention seeks to maxim ise thermal insulation properties without interfering with bindings.
  • the underside strip of M iller transitions under the bal l of the boot, thereby interfering with the purchase thereof when walking.
  • the present covering com prises a longitudinal arch ladder which is more rearwardly located so as to go under the arch of the boot between the ball and heel voids, thereby leaving both the ball and the heel of the boot entirely or at least substantially exposed.
  • the longitudinal arch ladder may locate rearwardly more than 30% of the length of the binding from the front.
  • the longitudinal arch ladder may start more than 100 mm from the front of the covering, such as at a pproximately 118 mm as shown, thereby substantially exposing the ball of the boot so as to not be tread upon in use.
  • M iller requires a very thin strip for wal king on, unlike the longitudinal arch l adder wh ich can be of a thicker more insulative material (such as neoprene) as the present longitudinal arch ladder is not stepped upon whilst walking, thereby al lowing for enhanced thermal insu lation underfoot without affecting footing purchase when wal king.
  • M iller specifically states that the downward slope of the rearward upper edge is critical as it leaves the entire boot shaft exposed for access for boot adjustment mechanisms.
  • a topl ine intersecting plane is substantial ly horizontal (i.e . less than 20° or 10° from the horizontal) so as to adequately cover the heels.
  • the present covering adequately covers the toes of the ski boot.
  • the unitary construction covering is made from the constituent pieces is shown in Figures 11 and 12 such that stitching between the vam p and the toe box allows for fine control of the shape and/or configuration of the toe box al lowing the toe box to lie closely against the toe box right down to the toe binding extending therefrom, thereby adequately covering the toe box unlike M il ler which leaves a portion of the toe box exposed (see Figure 1 of M il ler).
  • prior art coverings such as M iller em ploy strips of material to hold the ski boot cover to the boot
  • present covering may be of integral construction in that the longitudinal arch ladder and the heel counter may be continuously adjoining and made of the same material as the vam p and/or toe box so as to more effectively enhance thermal insulation behind the heel and under the arch of the boot as compared to the non - insulative straps of M il ler.
  • the present covering provides whole-of-foot thermal ly insulative encapsulation by having adequate coverage across the heel (which thermal ly insulates the Calcaneal branches of the Peroneal artery) and the toes with a high-grade neoprene barrier.
  • an interior surface of the toe box may com prise a frictional ly enhancing material such as a coating of rubber, silicon, latex or the l ike for sticking to the toe of the ski boot in use to prevent the toe box from riding up from the toe of the boot.
  • a frictional ly enhancing material such as a coating of rubber, silicon, latex or the l ike for sticking to the toe of the ski boot in use to prevent the toe box from riding up from the toe of the boot.
  • the quarter of the present covering is laterally located and com prises the quarter surface fasteners on an inner surface thereof which lies over and attaches to the distal end of the heel counter there underneath having corresponding heel counter surface fasteners on an outer surface thereof.
  • Such a manner of fastening prevents ingress of snow from the direction of travel and loosening of the attachment as com pared to the arrangement of M il ler which has the opposite configuration.
  • the ski boot covering may be integral ly formed from at least one first piece stitched to at least one second piece at a stitch l ine, the stitch l ine intersecting between th e vam p portion and the toe box portion.
  • the longitudinal arch ladder may locate more than 30% along a longitudinal length of the covering from a front of the toe box.

Abstract

L'invention concerne un revêtement de chaussure de ski thermiquement isolant comprenant un corps de structure unitaire ayant une empeigne, un embout de protection, une échelle de voûte plantaire longitudinale, un quartier et un contrefort ouvrable formés d'un seul tenant. Ces parties de corps contiguës en continu comprennent un matériau isolant pour fournir une encapsulation thermiquement isolante du pied entier, y compris en ayant une couverture adéquate à travers le talon (qui isole thermiquement les branches calcanéennes de l'artère péronière) et au niveau des orteils et qui n'interfère pas avec les fixations ou l'adhérence pendant la marche.
