Definitions

  • the invention relates to a ski boot shell and a ski boot as such comprising such a shell. It also relates to a method of manufacturing a ski boot shell. Finally, it relates to a series of ski boots and a method of manufacturing such a series.
  • a ski boot generally consists of a rigid shell, obtained by injection of a plastic material into a manufacturing mold, on which is fixed a hinged collar of plastic material, similarly obtained by injection, intended to cover the lower leg.
  • This set forms a ski boot shank of plastic material with a hardness generally of between 40 and 60 Shore D.
  • the method of injection of the shell and the collar requires very expensive manufacturing molds.
  • the hull is intended to surround the foot and corresponds to a given size. It comprises an outer rigid sole comprising standardized front and rear sidewalks intended to cooperate with the jaws of respectively an abutment and a heel of a fastening device of the boot on the ski.
  • a so-called Zeppa sole is usually integrated in the shell, then an inner comfort liner in which there is usually a sockliner. It is known to provide a shell of different size by full size, that is to say comprising a different length of its sole, between the two sidewalks, as well as dimensions that are generally different to correspond to feet of different size, according to standardized volumes such as the Mondopoint standard for example. These shells therefore require a different manufacturing mold by size. It is then known to provide two different half-sizes for each shell by being able to integrate two slippers of slightly different volume or with two insoles of different thickness in the same hull, which allows to multiply the possible choices for the skier. Then, the spacing of the shoe attachment device on the ski, between the stop and the heel, is adjusted to the dimension of the outer sole of the ski boot for the practice of skiing.
  • ski equipment rental shops must have series of ski boots of all sizes, to provide customers with a ski boot adapted to their size. Then, when a customer has chosen his shoe, it must be offered a ski to his size: the spacing of the ski fixation device chosen rarely corresponds to the ski boot chosen, since the previous ski hire had often a different shoe size, which requires the adjustment of this spacing to adapt to the chosen ski boot.
  • ski equipment rental shops must provide in practice many adjustment operations, which takes time and induces risks of error, and must have a series of shoes of all sizes and half sizes, which represents a heavy investment.
  • the document US2008196275 proposes a solution in which a series of shoes extending from the size 23 to the size 34 uses only three different soles, ie three different lengths involving only three corresponding different spacings between the front stop and the heel of a shoe attachment device on a gliding board.
  • this solution is advantageous in that it greatly reduces the need or the risk of adjustment error of the shoe attachment device on the ski.
  • the solution offers two shoe shells of different size for each sole length, ie a total of six different shells. Each of these shells then receives two inner slippers of different size to finally form two different sizes, which makes it possible to reach the twelve different sizes sought.
  • EP1952711 proposes an alternative solution according to a similar approach in which a series of shoes makes it possible to reach twelve sizes from four different lengths of sole, and three different shells per sole length. This solution represents the same disadvantage as the previous solution since it finally requires twelve different molds to make twelve different shells.
  • an inner shoe comprising a sole and side walls is provided, suitable for integration into a conventional rigid shell of a ski boot so as to reduce the size defined by this rigid shell .
  • the invention is based on a ski boot 1 comprising the usual and known components, in a form as illustrated in FIG. figure 1 .
  • It comprises a rigid shell 2, generally made of a plastic material such as polyurethane hardness between 40 and 60 Shore D or any other material of equivalent rigidity, obtained by injection, surrounding the skier's foot.
  • These two rigid elements, forming a rod are provided with a central notch to allow a spacing facilitating donning and heaving.
  • this notch is interconnected by fastening means 4 for bringing these flaps together, closing and tightening of the rigid rod of the shoe formed by the meeting of the shell 2 and the collar 3.
  • the shell also incorporates in its lower part a rigid sole 5 comprising standardized front and rear sidewalks 6 on which are fixed the jaws of a fastening device of the boot on a ski, not shown.
  • this rigid rod consisting of the assembly of the shell 2 and the collar 3, may have any other structure, so as to form a rigid assembly, whose rigidity is equivalent to that of a hardness polyurethane between 40 and 60 Shore D. It can also include some sub-parts of small surface of more rigid or more flexible material. This structure can in particular be obtained by a double injection process of plastic material.
  • the rigid shell may incorporate a sole, such as a sole commonly called Zeppa, manufactured separately and inserted into the shell, to finalize the lower part of the hull, according to a well known method.
  • a sole such as a sole commonly called Zeppa
  • This so-called Zeppa sole generally has a substantially horizontal upper surface and a protruding lower portion intended to be housed in a longitudinal groove formed in the shell, at the sole of the boot, during the injection process.
  • the advantage of this manufacturing process is that it makes it possible to obtain a relatively constant thickness shell by injection, and on the other hand the Zeppa by a simple and inexpensive molding whose positioning within the shell finally makes it possible to form the larger volume of material needed in the bottom of the shell , while obtaining thermal insulation at the connection between the Zeppa and the hull.
  • a comfort liner 10 of volume corresponding to the internal volume defined by the rigid rod, is then inserted into this rod, and intended to receive the foot of the skier.
  • the comfort boot marries at best the inner surface of the rigid upper of the boot to guarantee a good transmission of the efforts of the skier towards the ski to obtain a good driving of the skis.
  • the liner has a much more flexible structure than the rigid upper of the shoe to provide minimal comfort to the skier whose foot and lower leg are directly in contact with the shoe.
  • the invention is based on the use of a complementary component, called shoe, intended to be inserted into the substantially conventional rigid shell of a ski boot so as to reduce the size of this rod.
  • a complementary component called shoe
  • size will be used to mention whole sizes, whose dimensions are normalized. However, the term size can incorporate a broader meaning, which will be explained later.
  • This solution allows a single injected shell, using a single injection mold, to be used for several different sizes of ski boots, which represents a significant economic gain in the manufacture of the shoe series, also because of the inexpensive obtaining of the shoe.
  • the Figures 2 to 9 illustrate an embodiment of two shoes according to the invention.
  • the hoof 20 Figures 2 to 5 differs essentially from the shoe 20 ' Figures 6 to 9 by the smaller thickness of its walls 21.
  • the outer volume of the two shoes remains almost identical, since they are intended to be inserted into an identical outer rigid shell, obtained by the use of the same manufacturing mold.
  • the internal volume of the shoe 20 is greater than that of the shoe 20 ', the two inner volumes and dimensions of each shoe 20, 20' are defined so as to reduce respectively by one and two shoe sizes the size initially defined by the outer rigid shell, according to the usual size standards.
  • the size of the first shoe 20 is provided to cause the reduction of a size of a certain rigid shell, while the size of the second shoe 20 'is provided to cause the reduction of two sizes of the same rigid outer shell.
  • the walls of the first shoe therefore have a total thickness so as to reduce the inner length of the shell by 10 millimeters
  • the walls of the second shoe 20 ' similarly have a total thickness so as to reduce the inner length of the shell of 20 mm.
  • the front wall 26, 26 'of each shoe 20, 20' is chosen thicker than the rear wall 27, 27 '.
  • the relative thicknesses of these walls could be modified, as long as the sum of the thicknesses of the front walls 26, 26 'and rear 27, 27' represent a value of one or two sizes for respectively the first shoe 20 and the second shoe 20 '.
  • the side walls of each two shoes 20, 20 ' have a thickness preferably lower than that of the front and front walls, which decreases in the upper part to stop tangentially to the inner wall of the outer shell, and form a continuous and comfortable interior volume .
  • the shoe 20, 20 ' comprises a substantially horizontal sole 25, 25' intended to receive the support of the foot, and vertical walls 21, 21 'intended to at least partially surround the foot of the skier, so as to cover his toes at the front and up to the ankle at the back, above or below the malleoli to the desired accuracy.
  • the shoe 20, 20 'further comprises two openings 22, 22' in its sole 25, 25 'to facilitate its positioning in a shell, as illustrated with reference to the figure 11 .
  • any centering or positioning means could be provided.
  • the shoe 20, 20 'further comprises a notch substantially vertical 23, 23' at its front and rear ends to allow flexibility of its walls 21, 21 'which facilitates its insertion and removal in a rigid shell shoe ski.
  • the figure 10 illustrates by way of example the lower part of a rigid shell 2, which is truncated to facilitate the representation, which has a traditional shape with a sole 5 forming sidewalks 6 at its front and rear ends.
  • this sole comprises bosses 7 of shape corresponding to the openings 22, 22 'of the shoes 20, 20'.
  • the latter thus have a shape adapted for a housing in the rigid shell 2 of the shoe, so that their walls 21 come into contact with the inner surfaces of the walls of the rigid shell, according to an assembly illustrated by the figure 5 .
  • Boss 7 comes to occupy the opening 22 of the sole of the shoe 20 so as to ensure the establishment and maintenance of the shoe.
  • the shoe 20, 20 ' is obtained by a simple and economical manufacturing process, based on expanded polyurethane to obtain a semi-rigid component, of hardness of the order of 25 Shore D, between 20 and 30 Shore D, whose side walls comprise a thickness of less than 20 millimeters.
  • the shoe can be made of rubber, a recycled material, so as to obtain an equivalent hardness.
  • the shoe is of simple shape and in an expanded material, which allows the implementation of a simple process, using a low pressure and an inexpensive mold especially as it is no need to get a clean and precise finish.
  • Such a shoe makes it possible to modify the size of a rigid boot shell by integrating it into the shell, without requiring the manufacture of a different shell, of different size, and thus without requiring the use of another manufacturing mold. of a hull, which greatly reduces manufacturing costs.
  • several shoes 20, 20 'of the same external volume and different interior volume can allow, by their insertion in the same shell, to obtain several shoes different size.
  • the same shell can either receive no shoe, a shoe 20 of the first size, or a shoe 20 'of second size, which allows the same rigid shell to be used to form three ski boot cases of different size.
  • more than two shoes could be used for the same hull.
  • the invention also relates to a series of several shoes including a number of shoes multiple of three, that is to say three, six, nine and twelve ski boots, for which the same shell is used to obtain three sizes different.
  • a number of shoes multiple of three that is to say three, six, nine and twelve ski boots, for which the same shell is used to obtain three sizes different.
  • each shell one can either insert the traditional Zeppa sole, either a first shoe 20 or a second shoe 20 'of smaller internal volume, each shoe may or may not be associated with the sole Zeppa, which can optionally be integrated into the hoof.
  • This makes it possible to achieve three assemblies equivalent to three shells of different size from a single rigid outer shell manufactured by plastic injection.
  • an injected collar is provided by injected shell, which also allows to use the same number of different collars as the number of shells and therefore a reduced number of injection molds to obtain the different shoes of the series.
  • shoes of different size use only a small number of different shells, it follows that a series of shoes requires a reduced number of different settings of a shoe attachment device on a ski, more specifically a shoe. setting for each rigid outer shell, which is very advantageous, as has been seen before.
  • the invention is not limited to obtaining the series of ski boots detailed above. Any other series could be envisaged, including the use of at least one shoe to reduce the size of an injected shell to obtain two different sizes for a single injected shell, depending on the insertion or not of a shoe.
  • the concept of the invention has been made explicit for the inexpensive manufacture of a series of shoes, in order to obtain different whole sizes, according to the mondopoint size standard. It is naturally obvious to use this same concept to obtain half sizes, or sizes defined by any other standard.
  • the same concept can be used to form different shoes of different internal width, for example at the metatarsophalangeal joint, in order to use the same shell for maximum comfort, in the case of a large width, or for a higher performance, for example for the competition, in the case of a reduced width.
  • the concept of the invention can make it possible to modify the internal dimension of a shell in all directions, not only its length. We therefore mean by size the inside footwear volume offered by a shoe, considering all directions.
  • the invention also relates to a method of manufacturing a ski boot shell, comprising a step of manufacturing an external rigid shell by injection of rigid plastic material and characterized in that it comprises a step of manufacturing a a shoe and a shoe insertion step in the outer rigid shell.
  • the step of manufacturing a shoe can consist of a manufacturing from an expandable plastic material.
  • the invention also relates to a method of manufacturing a series of ski boots, comprising a step of manufacturing at least two identical outer shells 2 by injection of rigid plastic material, characterized in that it comprises a step of manufacturing a shoe 20 and then a step of inserting the shoe 20 into an outer shell 2 so as to obtain at least two ski boot shells of different sizes and / or in that it comprises a step of manufacturing two different hooves 20; 20 'then an insertion step of each shoe 20; 20 'in an outer shell 2 identical so as to obtain at least two ski boot shells of different sizes.
  • the shoe 20, 20 has been illustrated by way of example but it could have other geometries without departing from the concept of the invention.
  • the hoof can integrate the structure of the traditional Zeppa and be integrated in a hull to replace the Zeppa, or not integrate it and be added in addition to the Zeppa in a hull.
  • its side walls may have other shapes, more or less important heights, less regular around the perimeter of the foot. However, these side walls are sufficient to allow the reduction of at least one size by their insertion into a certain shell, which requires a minimal area distributed on the periphery of a skier's foot.
  • the side walls of the shoe advantageously occupy all the periphery of the sole, so as to be able to completely surround a skier's foot, or more precisely the comfort boot comprising the foot of a skier.
  • This circumference may not be completely continuous, grooves, openings, or interruptions may be provided, but without overly interrupting the side walls that occupy at least half of the periphery of a foot to fulfill their function.
  • the fact of forming perforated walls can reduce the weight and cost of the hoof.
  • these walls have a height sufficient to cover the side of a foot, come at least a little on the top of the foot, to define a sufficient volume around the foot.
  • the three components of the wall of the resulting shoe that is to say the wall of the outer shell, the wall of the shoe, and the wall of the comfort shoe, are sized to bear against each other so to obtain a powerful shoe in the transmission of efforts from the foot to the ski.
