Definitions

  • the sheet material sections are warmed to enhance their deformability, and are then press-formed in warmed condition so as to conform to the contour of that part of the foot with which they are to be associated when the boot is completed. They are subsequently maintained under pressure in their deformed state until they have cooled whereupon they are joined into the form of a ski boot.
  • the present invention relates to footwear in general, and more particularly to ski boots. Still more specifically the invention relates to a ski boot and to a method of making the same.
  • ski boots must withstand particularly severe conditions of use, especially the uppers of such boots which must have high mechanical strength and be water-tight.
  • boots are made of leather and, in view of the aforementioned requirements, heavy cowhide is usually used for this purpose. This, however, is expensive and must be subjected to a special treatment in order to make it watertight.
  • a more particular object of the present invention is to provide a shoe, particularly a ski boot, which is lighter,
  • Patented Dec. 8, 1970 less expensive, more Water-tight and more resistant to damage than those known heretofore.
  • An additional object of the invention is to provide a method for accomplishing the aforementioned purposes.
  • one feature of my invention resides in the provision of a shoe, particularly a ski boot, which consists at least in part of a plurality of pre-cut sections which are joined together along respective seams. At least some of these sections consist of laminar material made up of alternating layers of which at least one is a fabric layer and at least one other is a layer consisting of natural or synthetic resin material, such as natural or synthetic rubber or other suitable lastic materials.
  • the resulting shoe or boot has the advantages over leather shoes or boots which have heretofore been attained by making shoes or boots from synthetic plastic material or vulcanized rubber, but is significantly less expensive to manufacture because it can be produced by resorting to machines con- Nentionally used in the making of leather shoes or boots and obviates the need for investment in forms or molds such as have heretofore been necessary for the making of rubber or synthetic plastic shoes or boots.
  • the laminar material which, as pointed out above, consists of one or more layers of fabric embedded between outer layers of natural or synthetic plastic material.
  • the resulting laminar material is a flat sheet material and the sections which are pre-cut therefrom in the manner in which this is generally known in the shoe-making or boot-making art, are subsequently subjected to the influence of elevated temperatures so as to make the resin material readily deformable.
  • the sections are subjected to pressure in press forms and are deformed into a contour corresponding to the contour of that part of the human foot with which they are to be later associated when assembled into a completed shoe or boot.
  • the sections may be given a slightly concave configuration, or be otherwise deformed as necessary. They are then maintained under pressure while they cool and, When they are subsequently removed from the press forms, they retain their new shape or contour either completely or at least substantially so that they are then ready for joining in the same manner in which it is accomplished in the manufacture of leather shoes or boots.
  • FIG. 1 is a plan view of a pre-cut section prior to deformation
  • FIG. 2 is a schematic detail view of a heating arrangement for heating the pre-cut section of FIG. 1;
  • FIG. 3 is a schematic vertical section through a press form for giving the section of FIG. 1 a desired contour
  • FIG. 4 is an elevation of the pre-cut shown in FIG. 1 after it has undergone treatment in the devices of FIGS. 2 and 3.
  • the pre-cut section 1 shown in FIG. 1 has been severed in suitable manner, for instance by cutting, stamping or the like, from a sheet of laminar material consisting, as already pointed out earlier, one or more layers of fabric embedded between respective layers of natural or synthetic rubber or other suitable synthetic material.
  • it is preferably to use at least two layers of fabric, although a single layer is conceivable, because two layers will provide the high mechanical strength which is desired.
  • the fabric of course serves to limit the extendibility of the resin material so as to hold this value to that which is conventionally found in the type of leather used for the making of shoes and/ or ski boots.
  • the resin material in which the fabric is embedded may be natural rubber, synthetic rubber, synthetic plastic material on the basis of ⁇ Isopren, Igelit, polystyrene, acrylic acid ester, as well as others.
  • the layer of resin material which is the outside layer may be treated in known manner so as to provide a desired surface appearance. For instance, it may be given a simulated grain so as to simulate leather, it may be provided with a pattern, or it may be treated in other desired ways. Providing a simulated grain or pattern has the additional advantage that any damage to the surface, resulting for instance from contact with portions of the ski binding or the like, will not be as readily evident as if the surface is smooth.
  • the inner side of the respective section may be further reinforced with a layer of suitable material, for instance rubber in synthetic plastic material.
  • a layer of suitable material for instance rubber in synthetic plastic material.
  • FIG. 1 where the pre-cut section 1 is shown to be provided with a bonding agent 2, here assumed to be a thermoplastic bonding agent such as neoprene, onto which a reinforcing layer 3 is placed.
  • the thus-produced blank is heated.
  • This is conventional, as is the fact that the two platens are movable towards and away from one another, or one platen is movable towards and away from the other.
  • the blank consisting of the layers 1, 2 and 3 is heated to a requisite elevated temperature, for instance on the order of approximately 150 C., rendering the pre-cut section 1 plastic and activating the bonding agent 2.
  • the blank 1, 2, 3 is placed into a pre-form such as that shown in FIG. 3.
  • a pre-form such as that shown in FIG. 3.
  • the pre-form 6, 7 is advantageously subjected to continuous cooling because this, in conjunction with the preliminary heat treatment outside of the pre-form, makes it possible to obtain a high speed of production.
  • the cooling which may be effected by circulatin cooling water through the sections 6 and 7 so as to reduce the temperature to only a few degrees centigrade, serves to depress the temperature of the blank 1, 2 and 3 to room temperature quite quickly, thus accelerating production, and during such cooling of the blank the laminar material of the pre-cut section 1 loses the increased plasticity originally imparted to it by the heating step.
  • the bonding agent 2' also hardens and the reinforcing layer 3, which may be rubber, leather or another suitable material as already pointed out, is tightly bonded with the deformed pre-cut section 1.
  • the resulting deformed blank is demoved from the press form 6, 7 and will retain its new shape completely or at least substantially completely.
  • the configuration of the thus-obtained deformed blank is shown in FIG. 4 in a view of the exterior of the blank.
  • the laminar material from which the pre-cut sections are made consists of vulcanized fabric and rubber layers.
  • the reinforcing layer 3 can be made from the various materials already mentioned, and that it not only serves to reinforce the pre-cut section 1, but also serves to retain the same in the deformed shape thereof by preventing it from returning to planar state.
  • an upper consisting at least in part or a plurality of precut sections joined together along respective seams, at least some of said sections consisting of laminar material comprising at least two fabric layers, at least one layer of resin material intermediate said fabric layers, and at least two outer layers outwardly adjacent to the respective fabric layers with at least one of said outer layers also consisting of resin material.
  • said resin material is an acrylic-acid-ester-based resin.
