Definitions

  • the invention relates to the field of sliding sports shoes and is particularly interested in shoes comprising a rigid articulated outer shell and containing a flexible inner liner, such as those used for alpine skiing, ski touring, cross-country skiing and snowboarding.
  • Ski boots are generally formed of a rigid outer shell comprising an upper collar articulated on a lower shell. Inside this shell is housed a flexible liner which is often removable. Such a liner generally comprises an upper part intended to surround, at least partially, the lower leg and the shin of the user and a lower part intended to surround the foot.
  • the collar of the outer shell can pivot relative to the bottom of the shell. This pivoting or movement can be oriented backwards or forwards.
  • the upper part of the inner liner which is generally not flexible enough, cannot follow, naturally or at least not completely, the tilting of the collar and tends to resist and hinder the movement of the skier's leg backwards or forwards.
  • Traditional inner slippers generally include a central opening. This central opening can be closed by a tab. At the front, on either side of the opening, there are also sometimes notches made in the wall of the upper, near the connection between the upper and lower parts of the slipper and at the height of the instep, intended to facilitate the movement of the upper part of the slipper in relation to its lower part. These notches can be filled in particular by a small piece of fabric. This textile piece is rather used in order to guarantee the waterproofness of the slipper in this area and to prevent water or snow from entering the foot. However, the notches are insufficient to allow free movement of the upper part of the liner in relation to its lower part, in order to best follow the pivoting of the cuff.
  • the patent DE3527135 describes a so-called "rear entry” ski boot, formed of an inner liner and an outer shell.
  • the outer shell comprises an upper part in two parts, front and rear, articulated on a lower part.
  • This boot is provided with a connecting element mounted between the rear part of the upper part of the shell and the upper part of the inner liner.
  • This connecting element also makes it possible to secure an insert housed between the shell and the liner and intended to fill the intermediate space to thus ensure better support of the foot in the boot.
  • both the connecting element and the insert are additional complex parts which must be added to the boot.
  • this boot is not intended to facilitate walking, and therefore does not have a disengageable upper part.
  • the patent FR2682265 describes a ski boot comprising an outer shell formed by a collar pivotally hinged on a lower shell, as well as an inner liner whose upper comprises upper and lower parts.
  • the boot is provided with a device ensuring a sliding connection between the inner liner and the collar of the outer shell.
  • This device comprises a hooking plate carried by the liner and intended to receive a lug formed on the internal part of the collar of the shell.
  • the parts located at the rear, respectively of the shell and the liner are connected while having a freedom movement allowing the two parts to pivot relative to each other.
  • this connecting device is bulky and complex and also requires structural adaptations to be made to both the outer shell and the inner liner.
  • the invention aims to overcome the technical problems previously raised by known shoes by proposing simple means of dynamic connection between the inner liner and the articulated collar of the outer shell, these means being intended to offer more movement towards the rear and/or the front of the upper part of the liner relative to its lower part and thus to allow it to follow the pivoting of the collar.
  • a first subject of the invention is a sliding sports shoe comprising, on the one hand, an outer shell comprising an upper collar articulated on a lower shell bottom and, on the other hand, an inner liner formed of an upper part intended to surround, at least partially, the lower leg and the tibia of the user and a lower part intended to surround the foot, characterized in that the upper part of the liner is provided with a flexible connecting element projecting at the rear and to the outside and intended to cooperate with a retaining element carried by the collar of the shell to ensure their mutual dynamic connection.
  • the connecting element is in the form of an open loop whose end strands are integral with the wall of the upper part of the shoe.
  • the retaining element is formed of a tab oriented downwards at the rear of the collar and delimiting an intermediate space with the external wall of the collar in which said connecting element is attached.
  • the retaining element is, for example, made in one piece with the shell.
  • the retaining element is formed of a bolt having at its periphery a grooved zone intended to receive said connecting element.
  • the shoe comprises a tightening strap fixed to the shell by means of the bolt and at least partially surrounding said collar.
  • this bolt is reported and screwed into a tapped bore made in the wall of the collar.
  • the connecting element projects above the shoe to jointly form a gripping means.
  • the connecting element is an elastically extensible link.
  • Another object of the invention is a shell for a sliding sports shoe comprising an upper collar articulated on a lower shell bottom, and a projecting element attached to the outer wall at the rear of the collar and intended to retain a connecting element carried by an inner liner which is housed in said shell.
  • the projecting element is formed of a hook oriented downwards at the rear of the collar and delimiting an intermediate space with the external wall of said collar.
  • the protruding element is made in one piece with the collar by molding.
  • the shell comprises a tightening strap fixed to the rear of the outer wall of the collar by means of the projecting element.
  • Yet another object of the invention is an inner liner for a sliding sports shoe, said liner being formed of an upper part intended to surround, at least partially, the lower leg and the tibia of the user and a lower part intended to surround the foot, characterized in that the upper part is provided with an elastically extensible connecting element intended to hook onto a retaining element carried by the shoe to ensure their mutual dynamic connection.
  • the invention is not limited to a shoe comprising an outer shell and an inner liner as defined above.
  • the invention also relates to a shell and/or an independent collar provided with a retaining element produced either in the form of an attachment then screwed onto this collar, or in the form of a single piece with this collar, for example by molding, co-molding or overmolding.
  • the invention can be applied to an inner liner provided with a connecting element and capable of being housed in different types of shells provided with an element capable of retaining this connecting element.
  • the connecting element thus forms a transmission belt, when the collar pivots backwards.
  • the pivoting of the collar forwards is accompanied by the return of the upper part of the liner to its starting position without the assistance of the connecting element.
  • This movement of the upper part of the liner is therefore reversible and thus makes it easier for the skier to walk or practice ski touring.
  • the inner shoe can still be removed from the shell by manually unhooking the connecting element from the retaining element. This unlocking is easily achieved because the connecting element is extensible.
  • the invention relates to the field of sliding shoes and, in particular, those intended for alpine skiing, ski touring, cross-country skiing and snowboarding...
  • shoes intended for these sporting activities generally comprise a rigid outer shell 1 formed of an upper collar 11 articulated, via a pivot axis 12, on a lower shell 13.
  • This shell 1 contains an inner liner 2, generally removable, which can be made of a flexible and deformable material.
  • This liner visible in isolation on the figure 8 (generally comprises a rod formed by an upper part 21 (only the end portion of this upper part is shown in the Figures 1 to 6 ) intended to at least partially surround the lower leg of the user, and a lower part 23 ( figure 8 ) extending the upper part 21 and intended to at least partially surround the user's foot.
  • the limit between the upper 21 and lower 23 parts of the slipper is materialized by a plane passing substantially through the axis of the malleoli and the instep of the user.
  • the slipper may be formed by assembling several parts, for example, sewn or glued together.
  • the wall of the slipper generally comprises an internal comfort layer, in contact with the user's leg and foot, an intermediate padding layer (not visible in the figures), and a more rigid external layer 21a, in contact with the external shell and intended to ensure the transmission of the forces from the leg to the shoe, as illustrated by the figure 8 .
  • An additional reinforcement element 21b also called a "spoiler” can be added to the upper part of the liner, against the outer layer of the liner, for better transmission of the forces from the leg to the ski equipment. However, this spoiler is optional and may not be used.
  • the upper and lower parts of the upper of the slipper meet substantially at the height of the regions of the user's malleoli and instep.
  • the upper is provided with a substantially vertical central opening 20 (the slipper being placed on a horizontal plane).
  • This central opening is positioned opposite the user's tibia and instep and facilitates the insertion of the foot into the slipper.
  • the opening generally extends towards the front of the slipper, in its lower part, towards the toes.
  • the central opening is intended in particular to allow the skier's foot to be put on and inserted into the boot.
  • the opening 20 is closed at the front by a movable tongue 22 projecting upwards, and side flaps.
  • the invention addresses the problem of the movement of a skier's leg forwards and backwards, which is generally hindered by an inner liner whose structure would not allow enough freedom for such relative movement between its upper and lower parts.
  • the shell of some ski boots includes a mechanical device designed to release the joint between the collar and the bottom of the shell to facilitate walking.
  • This device which allows you to switch to "walking mode" is generally called “ Ski / Walk ".
  • Ski / Walk the collar of the shell can tilt backwards and/or forwards relative to the bottom of the shell. The collar is then no longer locked to the bottom of the shell and can therefore pivot more freely.
  • the upper part of current inner liners is connected to the lower part without having sufficient relative freedom of movement, and it cannot therefore follow the movement of the collar of this shell.
  • the upper part of the liner then opposes a resistance to the movement which hinders the pivoting of the leg backwards and/or forwards. Consequently, the skier is hindered in his walking or, more generally, in the flexion movements of his leg, which raises difficulties of movement.
  • a difference in movement therefore exists between the outer shell and the internal slipper. This difference is noticeable and can therefore hinder the user in their movements.
  • the invention sought, on the one hand, to use the resilience properties of the material constituting the liner and, on the other hand, to integrate a means suitable and intended to ensure the transmission of movement between the collar of the shell, when it pivots around its articulation, and the upper part of the liner.
  • the solution to this problem consists in integrating into the shoe a flexible connecting element 3 projecting at the rear and outside of the upper part 21 of the liner 2.
  • This connecting element 3 is intended to cooperate with a retaining element 10 carried by the collar 11 of the shell 1 to ensure their mutual dynamic connection.
  • the connecting element can take the form of an element of circular section, such as a strand, a cable, a cord, or the form of an element of rectangular section, such as a flat ribbon, a strip or a strap.
  • the connecting element can be made of textile material and/or plastic. It can be formed of a single element, or alternatively be formed by assembling several parts.
  • this connecting element 3 is an elastically extensible link.
  • the connecting element 3 is in the form of an open loop whose end strands 3a (visible in dotted lines on the figure 8 ) are integral with the wall of the upper part 21 of the liner 2. These strands may be integral with the internal or external wall of the liner. They are, for example, sewn, welded or even glued to the wall of the liner. The closed external portion of the loop of the retaining element 3 cooperates with the retaining element 10.
  • the connecting element 3 is first sewn (by zigzag sewing of its two end strands 3a) to the surface of the outer layer 21a of the upper of the slipper. Then, if necessary during a later step, the rigid reinforcement piece or “spoiler” is added and secured to the outer layer 21a of the upper.
  • the retaining element 10 is formed of a tab 10a oriented downwards at the rear of the collar 11.
  • the retaining element 10 here forms a hook by delimiting an intermediate space with the outer wall of the collar.
  • the collar of the shell 1 is provided with a tightening strap 4 and the tab 10a is here mounted under the strap, for example by screwing.
  • the tab 10a can be mounted at the rear of the collar and secured by means of the same fastening system as that which is used to secure the tightening strap to the collar of the shoe.
  • the retaining element 10 can be produced, for example, in a single piece with the shell by molding (overmolding or co-molding) during the manufacture of the shell, in particular by means of plastic injection molding.
  • the retaining element 10 can be made of metallic material. The retaining element can then be attached to the wall of the collar by any known fixing means (screwing, riveting, gluing, high-frequency welding, etc.).
  • the retaining element takes the form of a downward-facing hook. More generally, the retaining element may be formed by an element that projects from the outer surface of the collar of the shoe, in its rear part. It may for example take the form of a lug, a tooth or a pin, insofar as its shape allows the retention of the connecting element 3.
  • connection between the connecting element 3 and the retaining element 10 is thus described as dynamic in that it will allow the transmission of movement between the collar 11 and the upper part 21 of the liner 2 and their joint drive, while taking up any intermediate play.
  • the liner and the collar are not necessarily articulated around the same axes of rotation. Indeed, the collar is articulated on the bottom of the shell around a first axis of rotation 12.
  • the upper part 21 of the liner is articulated relative to its lower part 23 at the border zone between these two parts, around a “fictitious” articulation axis, which mainly depends on the architecture of the liner in this zone.
  • the two articulation axes of the collar and the upper part of the liner do not necessarily coincide.
  • the collar and the upper part of the liner are not rotated along the same axis.
  • a relative translational movement between the upper part of the liner and the collar may result. Due to the extensible nature of the connecting element 3, this translational movement can be compensated, and thus not disturb the tilting movement of the leg backwards and/or forwards.
  • the retaining element 10 is formed by a bolt or a screw 10b ( figure 7 ) having a grooved peripheral zone 10c in which the connecting element 3 is wound at least partially.
  • This bolt is then added and screwed via its threaded end portion, into a complementary tapped bore made in the wall of the collar 11.
  • the groove 10c ensures the wedging of the connecting element 3 in the manner of a pulley groove.
  • the shoe includes a tightening strap 4 surrounding the collar 11, the latter is fixed to the shell 1 by means of the bolt 10b.
  • the lower face 10d of the bolt comes to bear against the tightening strap 4 in order to press it and hold it on the collar of the shoe.
  • the bolt 10b then performs a dual function, of fixing the strap 4 and of retaining the connecting element 3.
  • the connecting element projects above the shoe to jointly form a means of gripping and carrying.
  • the handle 5 shown in the figures would then no longer be useful and could be removed.
  • the profile and the material of the retaining element would be adapted for this dual use.
  • the user can secure the connecting element 3 with the retaining element 10 to promote the joint pivoting of the collar and the upper part of the shoe.
  • the connecting element 3 can detach from the retaining element 10, and use the connecting element as a means of gripping and carrying, the latter then protruding above the shoe.
  • Another advantage of the invention lies in the fact that it is possible to transform conventional ski boots equipped with tightening straps secured to the upper part of the collar by screwing, and whose liner includes at least a carrying handle.
