  • U.S. Patent 5,092,060 the subject matter of which is hereby expressly incorporated by reference, teaches a shoe comprising a sole with elastically deformable elements provided therein.
  • the elastically deformable elements provide energy conservation of the users' movements and thereby enhance the users' performance.
  • the elastically deformable elements taught by U.S. Patent 5,092,060 can be costly to manufacture and therefore it has been found desirable to provide elastically deformable elements which are more easily and inexpensively manufactured.
  • uppers for footwear typically is in form in the form of a relatively heavy material to provide adequate protection of the wearer and is often not lined. Thus, such does not provide a proper ventilation or provide for comfort of the upper portion of the foot of the wearer by softening the impact of the foot with the upper when worn by the wearer. It has therefore been recognized that a need exists for providing a lightweight upper or a liner for an upper which provides greater air flow and greater comfort when worn.
  • U.S. Patent 4,458,429 discloses a padded tongue for footwear comprising a front layer having multiple orifices passing therethrough, each orifice having a porous or reticular material therein wherein the tongue is assembled by adhering the front layer to the back layer along the circumference of the tongue and each of the orifices through to the meshes of an intermediate layer by heat-welding. It is also known from U.S. Patent 4,592,943 to utilize an apparatus and method of forming an open mesh belt on the fabric by heat or fusion bonding a web comprising conjugate fibers.
  • thermoformable fabric for the upper or the lining of an upper of a shoe so as to provide the benefits of comfort and air flow as explained above.
  • foam has been used to line shoe uppers.
  • foam is heavier, requires the use of cement, and is less breathable than thermoformable fabrics.
  • a foam is laminated to the inside face of the upper fabric of footwear and a further inner lining material such as a nylon tricot is applied, a three layered structure results.
  • Such soft layers are typically held in firm alignment by the use of cement provided between each layer.
  • Such construction results in an upper that has a high degree of stiffness due to the layers of cement.
  • a flexible, dimpled thermoformable fabric is used as an upper lining sheet. This lining sheet provides slight cushioning of a foam-lined upper but with less weight and greater breathability.
  • a stiff thermoformable fabric is provided as a rigid element for use as the midsole or as part of the midsole of footwear.
  • the shape of the rigid elements serve to provide cushioning by mechanical distortion when a load is applied to the midsole.
  • Figure 1 is a right side perspective view of a first embodiment of the shoe showing a dimpled upper lining in accordance with the present invention
  • Figure 2 is a top plan view thereof
  • Figure 3 is a right side elevational view thereof
  • Figure 4 is a rear elevational view thereof
  • Figure 5 is a perspective of a flexible dimpled thermoformable fabric utilized in the embodiment shown in Figure 1 ;
  • Figure 6 is a perspective view of a stiff thermoformable fabric with corrugations in the shape of truncated cones that is utilized in the second embodiment of the present invention.
  • Figures 1 through 4 illustrate an embodiment of the present invention where footwear 1 is illustrated with a lining for an upper 2 which is made of the flexible thermoformable fabric 4 shown in Figure 5, .and covered with a mesh shell.

  • a lining made from a sheet of flexible thermoformable material has a mechanical spring resiliency similar to that provided by a layer of foam. However, the sheet is allowed to float freely within some or all of the upper.
  • the lining is spot welded, glued, riveted or stitched to reduce relative movement between multiple layers forming a shoe upper.
  • the corrugations formed in the flexible fabric also provide cushioning for the user's foot, and provide increased ventilation between the user's foot and the upper.
  • the fabric may be a polyester, polymer, polyurethane, nylon or other plastic fiber.
  • the fibers of the fabric may be of any thickness that provides sufficient stiffness and abrasion resistance in the desired use. For example, a 1000 dernier fiber might be stiff and abrasion resistant enough for outdoor hiking boot applications while a lighter weight, such as 220 denier fibers, might be used in women's casual footwear.
  • the flexible thermoformable fabric i.e. the distance between the upper and lower faces of the material, must exceed twice the thickness of the textile sheet before it is provided with corrugations.
  • the upper to lower face distance in the corrugated flexible thermoformable material is in excess of 5 times the thickness of the textile sheet from which it is formed. The preferred thickness of the material depends on the intended use and the desired stiffness of the final product.
  • the method for manufacturing such a fabric as shown in Figure 5 is generally known, and includes heating the fabric to approximately 300 degrees Fahrenheit, depending on the material used, then pressing the material between a male and female die.
  • a stiff thermoformable fabric 6 is included in the midsole 10 of the footwear although it would be possible to also place this in an outsole.
  • sole is intended to include midsoles or outsoles.
  • Figure 6 shows an example of a stiff thermoformable fabric 6 with truncated cone corrugations 8, which can be suspended in a midsole of the footwar, thereby creating a sole with spring-like flexibility.
  • the truncated cones are arranged according to the biomechanics of a user's foot, and are suspended in the material comprising the midsole 10 of the footwear.
  • the midsole is made from a foam type material. The truncated cones, when suspended in the foam, provide the energy conservation sought.
  • the fabric used for the stiff thermoformable fabric in Figure 6 is generally thicker than that used in the fabric in Figure 5.
  • the fabric used for stiffening the midsole of the footwear may be of any thickness that provides a suitable stiffness for the intended use.
  • a carbon fiber and resin composite material may be only 0.5 mm thick and still be stiff enough to provide the desired midsole support.
  • a midsole of footwear provided with a thermoformable fabric in accordance with the invention should decelerate a missile striking the top surface of the midsole with a peak g force not greater than 28g. It is preferred that the material provides a peak g force of 12 to 18g in a traditional footwear missile impact test. It has been found that the maximum desirable thickness is approximately 3mm, while the average thickness is from 0.5 to 1.5mm for the materials used in the present invention.

Abstract

L'invention porte sur un tissu (4) thermoformable comprenant une semelle à laquelle est raccordée une tige, cette tige comprenant une doublure (2) constituée d'une couche de matériau thermoformable flexible. Une semelle intercalaire (10), pouvant être raccordée à la doublure (2), est fabriquée dans un tissu (6) rigide thermoformable pouvant être entouré d'une couche de mousse. Le tissu (6) thermoformable de la semelle intercalaire (10) peut être doté d'une pluralité d'ondulations (8) de sorte que la semelle intercalaire (10) ait une flexibilité analogue à celle d'un ressort. Des cônes (8)de différentes tailles sont dispersés dans toute la semelle intercalaire (10) de façon à correspondre à la biomécanique de différentes parties du pied d'une personne portant cette chaussure.
