Definitions

  • the invention relates to shoes in general, whether they have a flexible or rigid upper, and relates to an inner lining of their rod intended, among other things, to contribute to the comfort of the foot and ensuring contact with it for its maintenance.
  • the interior lining is fitted either on a cushioning element or interposed comfort cushion, or directly on the rod. More specifically, in the case of shoes whose upper is relatively rigid, such as ski and mountaineering boots, the cover is mounted on the inside of an element of padding such as a removable or fixed liner which is interposed between the upper and the foot. Through against, in the case of sports shoes with a flexible upper, such as tennis, basketball, running, ... etc., the interior lining is directly mounted on the rod.
  • the interior lining of these various types of shoes presents almost generally one or more relatively flexible pieces of fabric or leather and / or elastic on the side adjacent to the foot.
  • these pieces of fabric are composites that result from coating or bonding very low density foam on the back of a textile. They are thus able to conform to the rod and / or the element of padding on which they are mounted, and also able to deform later on the foot when the shoe is closed on the latter.
  • the pieces of fabric also provide soft to the touch and a pleasant feeling when putting on. They are revealed by against ineffective in dispersing or attenuating the slightest overpressure or the slightest hard point between the upper and the foot because of their low density and their great facility to compress.
  • this padding be made of a material easily compressible if it is the adjustment to the foot which is sought, or else it is carried out in one relatively firm material if it is the hold of the foot which is privileged. Indeed, a padding given in can not be both easily deformable, to wrap the foot, and firm, to hold it without flutter.
  • the padding which is polyurethane or foam rubber, therefore compressible, is made from a blank forming a pair of side panels and the fact that it is a lateral wedging in the ankle area.
  • the draft of the padding originally has shapes roughly corresponding to those of the foot, it is not necessary to firmly tighten the padding on the foot to hold it because the most protruding from the latter are housed in the blank; moreover, being essentially solve a lateral timing problem, this does not imply an intimate adjustment of the padding because an approximate approximation of the side panels of its blank on the foot is sufficient to ensure its adjustment to the width of the latter.
  • the small thickness of the pieces of fabric which cover the padding, as well as their texture have no capacity to absorb any protruding part of the foot and no ability to disperse the pressures that padding can apply locally to prominent parts of the foot.
  • the movements of the latter relative to the padding are not accompanied by these pieces of fabric. This results in rubbing, which is very often the cause of blisters, irritations and burning sensations.
  • the object of the present invention is to remedy the drawbacks of interior linings known and aims in particular to provide an interior covering which is suitable, by a layer adjoining the foot, conforming to small protrusions and / or protrusions extending to the surface of the latter and to accompany the foot in its micro displacements relative to the rod of the shoe.
  • the layer contiguous to the foot has, over at least one determined area, a structure composed of a viscoelastic substance mounted on a flexible film and stretchy, such as a fabric for example.
  • This structure constitutes the equivalent of a double skin thanks, in particular, to the thinness and the great capacity of elastic deformation of the viscoelastic substance combined with a low elastic modulus; these different characteristics give the viscoelastic substance, and thus the structure of the layer adjacent to the foot, a typical behavior of a so-called “delayed” elasticity and a natural tendency to press on the foot like a viscous gel conforming to the small prominences of the latter.
  • the micro movements of the foot relative to the upper of the shoe are essentially absorbed by the viscoelastic structure of the layer adjacent to the foot.
  • the layer thus structured in fact constitutes the interface element between the foot and the upper of the shoe which, if fitted on a padding, filters vibrations, shocks, ... etc., absorbs small displacements, and to some extent avoids putting the contribution of the foot while preserving the transmission of tactile sensations.
  • the interior covering comprises a layer contiguous to the foot made up, on at least one specific area, of a structure composed of a substance incompressible viscoelastic having a low elastic modulus and a flexible film and elastic which can be a woven or nonwoven material on which the latter is fixed.
  • a construction method the viscoelastic substance is contained in an envelope made using a flexible and elastic film.
  • the viscoelastic substance is, for example, a gel of polymers of density included between 1 and 2, and whose behavior is characterized by a "delayed" elasticity and by a elongation capacity at break greater than 400%, and preferably of the order of 700 to 900%.
  • the viscoelastic substance has a hardness, or resistance to deformation and penetration, between 15 and 45 Asker 'C', and preferably between 25 and 30 Asker 'C'. This hardness is measured with Asker hardness testers intended for substances classified in soft rubbers and plastics, including flexible cellular materials and elastomers, according to standard SRIS 0101 (Society of Rubber Ind. Japanese Standard).
  • the viscoelastic substance can deform under the effect of a stress in the manner of a viscous fluid, because its capacity elongation is important, and can return to its original shape like a spring but this after a certain period of time after the stress has ceased because its modulus of elasticity is weak.
  • this gel-like substance behaves like a viscous product for slow stresses, and as an elastic product for rapid stresses.
  • the viscoelastic substance is produced in the form of a thin sheet in a thickness close to 1 millimeter, and at most of the order of 5 millimeters.
  • the contiguous layer of the foot is provided with a structure composed of a viscoelastic substance bonded to a flexible film on at least one area of the foot with bony prominences.
  • the layer contiguous to the foot comprises several zones which are each provided with a structure composed of a substance viscoelastic attached to a flexible film.
  • the structure composed of a viscoelastic substance bonded to a flexible film has a thickness different from an area determined to another determined area.
  • the viscoelastic substance is relatively thick, for example 4 to 5 millimeters, which is used. In this way, the location of pressure points is avoided thanks to the conformation of this structure on a large contact area.
  • FIG. 1 illustrates, in perspective view, a shoe of the rigid shell type equipped with a comfort padding with an interior covering according to the invention.
  • FIG. 2 represents the shoe of FIG. 1, seen in cross section along II-II, with the user's foot positioned inside.
  • Figure 3 shows, in section, a detail of the interior trim of the shoe.
  • FIG. 4 illustrates, in perspective view, a shoe with a flexible upper also equipped with a interior covering according to the invention.
  • FIG. 5 is a cross-sectional view along V-V of the shoe of FIG. 4.
  • FIGS. 6 and 7 represent a method of constructing an interior covering, or lining, before mounting on the upper of a shoe, FIG. 6 illustrating the covering developed flat, and Figure 7 a section along line VII-VII of the trim of Figure 6.
  • the boot illustrated in FIGS. 1 and 2 is a ski boot with a rigid upper 1 which is provided with comfort padding 2, constituted by a slipper, which is interposed between the foot 4 of the user and the rod 1.
  • comfort padding 2 is produced, in a manner known per se, in a microcellular material, with a density less than 1, more or less compressible such as polyurethane or foam rubber, and has an outline of a footwear volume corresponding approximately to that, standard, of a 4 foot in a given size.
  • the padding 2 is covered by a covering interior of which a layer 3, contiguous to the foot 4, is provided with a structure 5 where a sheet thin of a viscoelastic substance 6 with low elastic modulus is bound to a flexible film and elastic 7.
  • This viscoelastic substance 6 is constituted for example by a gel of polymers with a density between 1 and 2, and its behavior is characterized by a elasticity "delayed” and by a capacity of elongation at break greater than 400% and preferably between 700 and 900%. Its hardness, measured with an Asker durometer, is between 15 and 45 Asker 'C', and preferably between 25 and 30 Asker 'C'.
  • the thin sheet of viscoelastic substance 6 has an approximate thickness of 2 millimeters and can reach 5 millimeters.
  • the structure 5 of the layer 3 retains a substantially flexibility comparable to that of traditionally used fabric pieces, that is, it can cover the padding 2 by faithfully following its shapes and accompanying its deformations subsequent when the rod 1 is tightened to close the shoe on the foot 4 of the user.
  • this structure 5 due to its incompressibility combined with its great elongation capacity at the rupture and its density greater than that of the padding 2, this structure 5 can be conform to the small prominences of the foot not taken into account by the draft of the volume footwear offered by the padding 2.
  • the viscoelastic substance 6 of the structure 5 deforms in the manner of a viscous fluid, becoming thinner at the location of the greatest pressures and thickening in the surrounding space subjected to lower pressures. This behavior results in intimate contact between the structure 5 of the layer 3 and foot 4, and thus an increased feeling of holding which allows the user to shoe to have a more precise gesture.
  • layer 3 relatively dense and incompressible in contact with the foot 4 and a padding element of lower density and compressible between this layer 3-5 and the rod 1; in this way, layer 3, with its structure 5, plays the role of a double skin because it conforms faithfully to the foot and its high elasticity allows it to support micro movements of the foot relative to the upper 1 of the shoe or even relative to the padding 2. This avoids friction which is likely to occur between the film flexible 7 and foot 4.
  • the interior covering comprising a layer 3 with a structure 5, as described with reference to Figures 1, 2 and 3, is suitable for a shoe with flexible upper 11.
  • the layer 3 with structure 5 is directly mounted on the flexible rod 11 whose outline it follows.
  • structure 5 has a viscoelastic substance which is under form of a thin sheet whose thickness is of the order of 1 millimeter. We preserve the so the ease of adjustment of the upper 11 of the shoe without weighing it down too much.
  • Figures 6 and 7 show a method of constructing an interior covering, one of which layer 3 provided with a structure 5 is associated with a support piece 22 which can constitute a comfort padding.
  • the latter possibly shaped to fit the substance viscoelastic 6, is fixed to the flexible film 7 of the structure 5, for example, by bonding films hot melt.
  • the zone 23 intended to be sewn and / or stitched, such as the border is devoid of viscoelastic substance 6.
  • a structure 5 near the foot many other adaptations of a structure 5 near the foot are possible without for this to depart from the scope of the invention. So the viscoelastic substance 6 of structure 5 can be accommodated, for at least part, in comfort padding 2 on the side facing the user's foot 4.
  • the layer 3 contiguous to the foot can be provided with a structure 5 composed of a viscoelastic substance linked to a flexible film 7, or linked to any other textile having equivalent properties, on only one area of the foot having bony prominences.
  • the contiguous layer 3 of the foot can comprise several specific zones provided, each of a structure 5 composed of a viscoelastic substance 6 fixed to a flexible film 7 or a textile, and this structure may have a thickness different from an area determined to another specific area.
  • structure 5 could be located in areas 12 and 13 corresponding to the malleoli 12 'and 13' of the foot 4.
  • a layer 3 provided with a structure 5 can obviously constitute the interior covering. a tongue of comfort padding or a slipper, and / or also the tongue 14 from the upper of a shoe.
