Definitions

  • the present invention relates to the technical field of manufacturing waterproof footwear, and for example but not exclusively footwear hiking, with an inner lining made from a material waterproof but permeable to water vapor. Its purpose is inner lining in the form of a waterproof liner, the method of manufacturing such a bootie, as well as an article of footwear equipped with this inner lining.
  • an article of footwear waterproof such as for example a hiking shoe
  • an inner lining that is waterproof and that is permeable to water vapor.
  • the inner lining due to its waterproof character, has the primary function of maintaining, with the best possible efficiency, the foot of user dry. Due to its vapor permeable nature, this lining inner function has the second function of allowing the user's foot to breathe and thereby reducing the occurrence of the phenomenon of sweating, which improves user comfort.
  • breathable membranes are by example in expanded microporous polytetrafluoroethylene. This type of membrane is for example described in patents US-A-3,953,566 and US-A-4,187,390. There are also other known types of breathable membranes currently marketed and produced on the basis of other microporous polymers (polyurethane, polyester, polyamide, etc.).
  • a first solution proposed to date by some manufacturers is to make these inner linings in the form of a flexible bootie, which is sewn and which is made entirely of a material having the required properties impermeability to water and permeability to water vapor.
  • the seams of booties are made perfectly waterproof, for example by means of bands waterproof that are glued to the seams or a gasket applied to the seams of the liner. This slipper is then positioned and fixed to inside the shoe.
  • a second solution consists in not making an integral liner manufactured separately, but to integrate the steps of setting up and fixing the inner lining at the manufacturing stages of the shoe.
  • this solution during the manufacture of the shoe, one comes fix the waterproof and breathable lining in relation to the original fitment of the shoe, by folding the free edge of the lining along its entire periphery, on the underside of the first shoe mount, and also folding the upper of the shoe on the underside of the first shoe, the edge of the lining being sandwiched between the upper of the shoe and the first of mounted.
  • a sealing sole for example plastic
  • This first variant has the disadvantage of not effectively preventing water infiltration from the outside of the shoe to the inside of the lining. In water can infiltrate between the sealing sole of the original passing through the upper of the shoe, then infiltrating by capillary action towards the inside of the lining by entering the non-sealed edge of the inner lining.
  • an internal fold is provided at the peripheral edge of the inner lining and a seal is applied, for example by means of a polyurethane adhesive, between the upper of the shoe and the underside of the first shoe.
  • the fold advantageously makes it possible, compared to the first aforementioned variant, to prevent the water which infiltrates through the upper of the shoe as far as the peripheral edge of the lining from being able to penetrate into the lining and rise by capillarity inside. of the lining.
  • the present invention provides a new solution for rendering waterproof a footwear item, while allowing the user's foot to breathe, which has all the advantages of the first solution mentioned above, without present the drawback linked to the problem of fitting the liner inside shoe, and which also has the advantage of being less expensive than the first solution.
  • the solution of the invention lies in the manufacture of a lining interior, which as the first aforementioned variant embodiment of the patent US 5,253,434 is in the form of a flexible bootie which is intended to be fixed inside a footwear, and which is made by assembling a rod flexible and a flexible sole.
  • the upper is waterproof water but permeable to water vapor and the sole is made of a material permeable to liquids; the liner also has an external coating of keeping in waterproof form, which covers the sole and only the lower part of the rod over its entire periphery, and which has the function of giving the covered parts with sufficient rigidity to keep them in shape while retaining some flexibility.
  • the sole can advantageously be made of any textile material at low cost, which significantly reduces the cost of the boot compared to the first above solution.
  • the coating by its stiffening function, allows advantageously to produce a liner whose lower part can be molded according to a shape adapted to the inside of the shoe, which makes it easier to put on subsequent placement of the slipper inside the upper of the shoe, and avoid creases in the liner when attached to the inside of the upper shoe, especially at the sole of the liner.
  • the upper and the sole are assembled transversely to each other, in particular by a Peripheral seam of Strobel type.
  • This variant has the advantage of simplifying the manufacture of the liner, and makes it possible to obtain a liner which intrinsically, that is to say without the tight stiffening coating, immediately presents a shape relatively well suited to the interior volume of the footwear.
  • the technical characteristics of this preferred variant of embodiment do not are however not limitative of the invention.
  • two configurations may arise.
  • the sole of the chasson has a larger area than the article's insole footwear, and is folded so as to form a peripheral rim located in the same substantially vertical plane than the upper of the bootie.
  • the sole of the bootie has a surface which is on the contrary smaller than that of the insole of the footwear, and the upper of the bootie is folded so as to form a peripheral rim located in the same plane substantially horizontal than the sole of the bootie; in this second configuration, the seam between the upper and the sole is in practice located under the arch of the user.
  • Another subject of the invention is a method of manufacturing a liner intended to be fastened inside an article of footwear to act as a lining interior.
  • a bootie is produced intermediate by assembling a rod, which is waterproof and permeable to water vapor, and a sole which is made of a material permeable to liquids; a rigid shape adapted to the interior volume of the footwear, and the lower part is impregnated intermediate liner with a liquid or semi-liquid material, capable of solidifying, so as to form a waterproof outer coating, which covers the sole and only the lower part of the upper of the intermediate liner over all its periphery, and which molds the covered parts into shape while retaining some flexibility.
  • the impregnation step is carried out by soaking the part lower of the intermediate liner in at least one bath containing in its form liquid or semi-liquid the material intended to form the stiffening coating waterproof.
  • it is a latex bath or of a synthetic elastomer.
  • a flexible intermediate liner 1 ′ is made from a flexible upper 2 and a flexible sole 3.
  • the rod 2 consists of three textile pieces 2 a , 2 b and 2 c sewn together.
  • the textile pieces 2 b and 2 c have the same geometry and are more particularly sewn together edge to edge according to a rear seam 4 a located at the heel of the boot.
  • the opposite edges of the pieces 2 b and 2 c are sewn respectively edge to edge with the textile piece 2 a according to side seams 4 b , the textile piece 2 a forming the front part of the liner.
  • the seams 4 a and 4 b are for example zigzag seams.
  • the textile pieces 2 a , 2 b , 2 c constituting the upper 2 of the liner are designed so as to be impermeable to water while being permeable to water vapor.
  • a breathable membrane 5 which is for example a film of expanded microporous polytetrafluoroethylene having the properties required above.
  • each textile piece 2 a , 2 b , 2 c constituting the rod 2 is formed by a laminate in four layers, comprising an outer layer 5 ′ commonly called charmeuse and consisting for example of a silicone polyethylene film, a first intermediate layer corresponding to the aforementioned breathable membrane 5, a second intermediate comfort layer 6 produced for example from a polyurethane foam, and an internal layer 7 which is chosen for example for its qualities of softness to the touch and its good capacity to absorb perspiration.
  • This layer 7 will for example consist of a textile based on synthetic fibers, the internal face of which, intended to come into contact with the foot, has undergone a woolen operation giving it a softer feel.
  • the respective seams 4 a , 4 b are sealed off, for example by applying a fusible sealing tape 8 to these seams.
  • the rod 2 is assembled transversely to the sole 3, by means of a seam 9 extending over the entire periphery of the sole 3. From preferably, but not exclusively, it will be a Strobel type seam.
  • the sole 3 is made of a material any porous liquid permeable, and does not use unlike to the constituent elements of the upper, a breathable waterproof membrane 5 and permeable to water vapor.
  • This sole 3 is for example constituted by a simple knit made from polyester fibers.
  • the geometry is adapted to the interior volume of the shoe in which the liner final will be inserted.
  • This shape 10 makes it possible to stretch the walls of the liner in it giving the appropriate geometry.
  • the lower part of the liner 1 ′ which is kept in shape is then impregnated with a liquid or semi-liquid material, which after drying solidifies in the form of a flexible external waterproof layer, such as the coating 12 of the liner.
  • This impregnation step can be performed by any known method of coating.
  • this impregnation step is carried out by simple soaking of the lower part of the liner 1 ′ in at least one bath of a material 11 in liquid form, which after solidification forms the coating flexible 12 of the liner of Figure 4.
  • the height of soaking the liner in the bath is referenced h .
  • the form 10 is not removed from the liner until the coating 12 has solidified, the lower part of the liner covered with this coating being thus molded into shape.
  • the coating 12 after solidification of the material 11 covers the outer face 3a of the sole 3, the seam 9 between the rod 2 and the sole 3, and goes back above this sewing, covering the lower part of the upper 2 over a height H , which corresponds substantially to the height of soaking h of the liner in the bath of material 11.
  • the lower part of the upper 2 and the sole 3 are thus advantageously molded into shape, according to a geometry perfectly adapted to the interior volume of the shoe, in which the liner is later intended to be fitted, which advantageously avoids the appearance of folds in the sole 3 and in the lower part of the upper 2 during assembly of the liner inside the shoe.
  • the better shape retention of the liner at the lower part of its upper 2 and its sole 3 facilitates the positioning operation of the liner relative to the upper of the shoe.
  • the upper 2 of the liner has a first front portion 2 'oriented substantially transversely to the sole 3, and which corresponds to the part of the liner commonly called the "tip" of the liner.
  • This point 2 ' is extended by a second portion 2 "which extends to the fold zone referenced B, which is substantially parallel to the sole 3, and which forms the part of the boot commonly called" above "the boot.
  • the 2 "portion of the rod 2 corresponds to the part which covers the user's foot at the level of the toes and the instep.
  • the fold zone B corresponds to a slope change zone, beyond which the rod 2 forms a third front portion 2 '''.
  • this portion 2 ''' starts substantially at the ankle of the user and rises above the ankle.
  • the so-called" lower "part of the rod 2, which is covered of the waterproof stiffening coating 12 corresponds to the lower part of the rod 2 which extends between the sole 3 and an upper limit situated at most at the level of the bending zone B.
  • the covering 12 preferably extends as far as possible up to this folding zone B. More particularly, but not exclusively, the covering 12 is produced so as to extend beyond the seam 9 between the sole 3 and upper 2 over a height H at least equal to 10mm, and is preferably made so as to cover at least the tip 2 'of the boot.
  • the process for producing a latex coating 12 of FIG. 3 mainly comprises four successive dipping operations, in four baths, an intermediate liner 1 ′ into which the form 10 has been introduced.
  • the first bath is a bath containing latex in liquid form, for example at room temperature.
  • the soaking operation is carried out by immersing the intermediate liner 1 'in the first latex bath over a given soaking height h 1 , for a sufficient time for the latex in liquid form to deeply impregnate and saturate the porous structure of the sole 3 of the intermediate liner 1 '.
  • the soaking operation in the first latex bath was carried out for approximately 15 seconds.
  • the intermediate liner 1 ′ is covered in the lower part with a first layer of latex taken from the mass of the intermediate liner and forming on the surface of the intermediate liner a thin film of latex.
  • the slipper is soaked in a second bath containing a product in liquid form capable of coagulating the latex in the usual way.
  • a second bath containing a product in liquid form capable of coagulating the latex in the usual way.
  • a product in liquid form capable of coagulating the latex in the usual way.
  • It will, for example, be a bath containing, in a known manner, a vulcanizing dispersion at room temperature, in the form of an aqueous solution containing one or more oxides, including for example zinc oxides, the soaking operation lasting approximately 15 seconds.
  • the soaking height h 2 of the liner in this second bath is strictly less than the soaking height h 1 in the first bath.
  • the bootie is then soaked in a third complementary latex bath at room temperature, for example for approximately 15 seconds.
  • the soaking height h 3 is provided at an intermediate level between the soaking height h 2 of the liner in the second bath and the soaking height h 1 of the liner in the first bath.
  • the first soaking operation in the first latex bath is for function of forming a first layer of latex which is taken in the structure of the intermediate liner which provides a hooking surface for the second layer latex formed at the end of the third bath.
  • the slipper is stripped of all impurity by being soaked in a fourth and final hot water bath, for example at a temperature of the order of 50C ° for about 15 seconds.
  • the intermediate liner maintained in shape is dried for example by passing through a tunnel oven at a temperature around 100 ° C. After drying, remove shape 10 from the liner, which is ready to be routed to the next stage of manufacturing.
  • the boot 1 of FIG. 4 can, before being integrated into a shoe, go through an intermediate step to check its tightness, which allows advantageously the manufacturer to subsequently guarantee the user the watertightness of the shoe.
  • This control step will be carried out for example by immersing the slipper in a water bath for a predetermined period.
  • the liner 1 of FIG. 4 is, in a first step manufacturing shoe, positioned relative to the rod 13 of the shoe and made integral with this rod 13, being sewn for example in the upper part with this rod.
