Definitions

  • This invention relates to a ski shoe which meets requirements of modern down-hill technique and is in addition extremely comfortable, fully impervious, has a dampening effect on elastic movements of the wearer and does not require any upkeep as distinct from known shoes.
  • the improved shoe comprises an upper of vulcanized rubber provided with an inner lining of wool or the like, bonded by vulcanization to a premolded sole of stiff rubber.
  • a wedge of cork conglomerate or the like is interposed between the insole and sole at the rear of the shoe.
  • FIG. 1 is a perspective view of the shoe from the front
  • FIG. 2 is a view from below
  • FIG. 3 is a diagrammatical longitudinal sectional view
  • FIG. 5 is a sectional view on an enlarged scale on line VV of FIG. 3
  • FIG. 6 is a longitudinal sectional view on an enlarged scale of the forward shoe portion
  • FIG. 7 is a longitudinal sectional detail view on an enlarged portion of the backward shoe portion
  • FIG. 8 is an axial longitudinal sectional view on an enlarged scale of an intermediate portion of the shoe bottom.
  • the sole 1 is formed with cross ridges of saw-tooth shape extending parallel with one another.
  • the ridges 1a at the forward sole portion are oppositely inclined to the ridges 1b at the heel portion.
  • the above tread pattern prevents slipping when the wearer walks intermediate skiing and simultaneously facilitates emergency unfastening of the safety ski fastenings.
  • the upper has bonded thereto by vulcanization two rubber flaps denoted by 3 carrying the lace engaging means.
  • the lace engaging means 9 for the fastening of the shoe comprises a number of metal eyelets 7, secured to the facing edges of the rubber flaps 3. Hooks 8 alter nate with the eyelets 7 and are secured to the rubber flaps 3 a certain distance from the edges of the latter.
  • the eyelets 7 and hooks 8 serve for fastening the shoe with all the advantages of a double lacing without the drawbacks thereof.
  • the upper 2 comprises, as shown in detail in FIG. 7, from the outside to the inside rubber layers 10, 12 alternating with cloth layers 11, 13, a layer of stiff rubber 14 and a layer of woolen fabric or the like acting as a lining 17 for the shoe.
  • the intermediate foam rubber layer 16 extends upwardly by a thickened portion 16a at the top edge of the upper.
  • an additional layer of woolen fabric 15 is arranged between the foam rubber layer 16 and stiff rubber layer 14.
  • a foam rubber layer 16b is interposed in the upper at the shoe tip, as shown in detail in FIG. 6.
  • the tongue 4 comprises from the outside to the inside a rubber layer 18, a cotton fabric layer '19, a stiff rubber layer 2%, a foam rubber layer 21 and a knitted fabric .layer 22.
  • fire knitted fabric layer extends laterally of the tongue to form a bellows 5 and is lined with two rubber layers 5a, 5b extending within the tongue 4 to cover both faces of the foam rubber layer 21.
  • the bellows 5 is vulcanized to the upper 2 at the upper portion which is covered by the rubber flaps 3.
  • the insole 6 comprises from the inside to the outside a layer of woolen fabric or the like 23, similar to the layer 17 lining the upper, .a foam rubber layer 24, an ordinary rubber layer 25, a stiff rubber layer 27 and a filler 28, likewise made of stiff rubber, interposed between the insole and sole 1.
  • a wedge 26 of cork conglomerate is interposed between the layers 25 and 27 at the backward shoe portion.
  • the insole 6 is provided with a foot-arch support 23a.
  • the shoe shape insures an excellent mutual adherence of the shoe and foot so that all movements performed by the wearer are accurately transmitted to the skis.
  • the components of the shoe upper described above are bonded by vulcanization to one another which, together with direct bonding of the sole to the upper by vulcanization results in a fully impervious shoe.
  • Aeration of the shoe inside results from compression and release by the foot during use of the foam rubber inserts 16, 16b, 21and 24.
  • a ski shoe comprising in combination; a seamless upper of vulcanized laminated rubber of diverse stiffness including .an outer'barrier of rubber layers alternating with fabric layers, an intermediate stiff rubber layer made of rubber having a comparatively greater stiffness than that of said rubber layers of the outer barrier, an insert of foam rubber and a layer of fabric such as woolen fabric applied to at least one face of said foam rubber insert, a sole of stiff rubber bonded by vulcanization to said upper, an insole including an inner layer of fabric such as woolen fabric, .a foam rubber layer, an intermediate rubber layer, a stiff rubber layer made of rubber having a comparatively greater stiffness than that of said intermediate rubber layer of the insole and a stiff rubber filler interposed between said stiff rubber layer and said sole, and a wedge made of conglomerate material such as cork conglomerate interposed between said layers of said insole.
