Description

Technical area

The present invention relates to the field of sports shoes, in particular the field of sports shoes comprising a rigid shell for skiing, skating, etc. The present invention relates in particular to a sports shoe with an exogenous rigid shell and a removable hiking-type internal shoe.

State of the art

Ski boots comprising an internal shoe and a rigid exogenous shell are known in the state of the art. The internal shoe can be extracted from the exogenous shell to walk more comfortably, or inserted into this shell to ski. An example of such a shoe is described in WO2009/097550 .

The document US 3645017 A also describes a sports shoe with an outer shell and an inner boot.

Brief summary of the invention

One of the problems with ski boots with an exogenous shell is the transmission of forces between the internal boot and the exogenous shell. In fact, the internal boot is generally not fixed to the exogenous shell, but can slide or move inside, which prevents effective transmission of forces and harms the ski style.

An aim of the present invention is to propose a new sports shoe with an improved exogenous shell.

• une chaussure interne ;
• une coque exogène dont les dimensions permettent d'y insérer ou d'extraire la dite chaussure interne, ladite coque exogène permettant de renforcer ladite chaussure interne et de la fixer sur un article de sport ;
• ladite coque exogène comportant une semelle et une tige ;
• la face interne de cette semelle comportant un motif en relief, par exemple des nervures et des rainures, coopérant avec un motif correspondant sous la semelle de la chaussure interne, de manière à positionner latéralement et en hauteur la chaussure interne dans la coque exogène.

According to the invention, these goals are achieved in particular by means of a sports shoe comprising:

• an internal shoe;
• an exogenous shell whose dimensions make it possible to insert or extract said internal shoe, said exogenous shell making it possible to reinforce said internal shoe and to attach it to a sports article;
• said exogenous shell comprising a sole and an upper;
• the internal face of this sole comprising a relief pattern, for example ribs and grooves, cooperating with a corresponding pattern under the sole of the internal shoe, so as to position the internal shoe laterally and in height in the exogenous shell.

This construction therefore provides a rigid attachment point (at least along the axis perpendicular to the foot) between the internal shoe and the exogenous shell.

In one embodiment, the internal shoe comprises a protruding pivot on the external face near the ankle,
said exogenous shell comprising a housing for housing the pivot.

This solution makes it possible in particular to join the internal shoe and the exogenous shell at an important point for the transmission of forces, particularly during turns on skis.

The exogenous shell may comprise a front part of the upper capable of pivoting relative to the sole around a first articulation, and/or a rear part of the upper capable of pivoting relative to said sole around a second articulation. The internal shoe can be inserted into the exogenous shell respectively extracted from the exogenous shell by rotating the rear part of the upper. Loops may be provided to keep the front rod part and the rear rod part closed and tight against each other. This construction allows easy extraction or insertion of the internal shoe, and effective support of this internal shoe at the ankle.

The housing for the pivot can be opened or closed by pivoting the front part of the rod and/or the rear part of the rod. A portion of the circumference of the housing can be formed by a notch on the part before the rod, and another portion of the circumference of this housing can be formed by a notch on the rear part of the stem. The protruding pivot on the internal shoe may include an annular groove to accommodate the notches. This construction allows a rigid connection between the pivot and the housing, and easy separation of these components, simply by opening the front or rear part of the rod.

The shoe may include an achillary reinforcement articulated relative to the sole of the exogenous shell and capable of being attached to the rear upper.

According to a characteristic independent of the presence of a pivot and a housing, the sole of the exogenous shell may include holes for the evacuation of water inside this shell. Advantageously, the exogenous shell has a largely perforated structure allowing the internal shoe to be seen and the water to evacuate.

The invention also relates to an exogenous shell as claimed.

Example(s) of embodiment of the invention

The sports shoe shown is a ski boot. The invention could also be applied to other types of sports shoes, for example skates, snowboard shoes, etc.

The sports shoe shown on the figure 1 comprises an internal shoe 3, illustrated in more detail on the Figure 5 , and an exogenous shell 1 illustrated on the figures 2 to 4 . The internal shoe 3 is intended to keep the foot warm, and to allow comfortable walking in town, at the ski restaurant or in the snow. The exogenous shell 1 is intended to stiffen this internal shoe and to allow it to be inserted into a ski binding or into another sporting article. The foot and ankle are held by the internal shoe, which has for example laces, and with greater pressure by the exogenous shell when it is closed.

The internal shoe 3 comprises different soft padding materials 35 ensuring thermal insulation, waterproofing and guaranteeing comfort. The sole of the internal shoe and the reinforcement hoops over the base and/or the upper can, however, be made of rigid synthetic materials. The internal shoe is however not entirely protected by the exogenous shell 1 and must therefore be made of waterproof materials. For example, the inner shoe can be made of leather, goretex, nylon, etc., with soft padding in synthetic or natural materials.

The outer shell 1 is for its part made of rigid synthetic material. Its structure is largely openwork in order to lighten it and show the internal shoe.

The dimensions of the exogenous shell allow the internal shoe to be inserted or extracted. As seen on the figure 2 , it comprises a sole 10, a front part of the upper 11 able to pivot relative to the sole 10 around a first articulation 110, and a rear part of the upper 12 which can pivot relative to the sole 10 around a second articulation 120. In a variant not illustrated, it is also possible to have only one of the two rod parts which is articulated. The internal shoe can be inserted into the exogenous shell, respectively extracted from this shell, by pivoting the front part of the upper 11 and/or the rear part of the upper 12, as seen in the figures 3 And 4 .In one embodiment, the internal shoe could however be extracted or inserted by pivoting only the rear part 12, the front part remaining in the position illustrated on the Figure 3 ; the pivoting of the front part, however, makes extraction easier, and also makes it possible to reduce the height and bulk of the exoskeleton if it remains on the ski. Reference 18 illustrates an achillary reinforcement pivoting around an axis 180 linked to the base of the exogenous shell, and which is fixed in the closed position against the internal face of the rear rod 12 by means of a tenon 182 inserted in an opening in this rear rod.

The exogenous shell 1 can be closed and tightened by means of shoe buckles, in this example two buckles 112 113 which make it possible to tighten the cables holding the front upper 11 tight against the rear upper 12.

The inner shoe shown on the Figure 5 comprises a base 31, an upper 30 and a sole 37. The reference 35 indicates the paddings. It closes by means of a lace 36 with a lace stop 34 which allows the lace to be tightened and the stop 34 to be hooked to a fixed point on the tongue 33.

The internal shoe 3 further comprises a pivot 300 on the external face of the ankle, which allows it to be fixed to the exogenous shell. A similar pivot could also be provided on the inside of the ankle, but proves to be inconvenient for walking, so that for many types of shoes it is preferable to give it up.

The exogenous shell has a housing 14 on the internal face of the ankle in order to accommodate this pivot. The housing is constituted by a semi-circular notch 140 on the front rod 11, and a similar notch 141 on the rear rod 12, which slide into a groove 301 in the pivot 300. The housing 14 can therefore be opened respectively closed by making pivot the front part of the rod 11 and/or the rear part of the rod 12 of the exogenous shell. The pivot 300 therefore constitutes a rigid attachment point between the internal shoe 3 and the exogenous shell 1, making it possible to transmit the forces of effectively between these two parts of the shoe.

In a variant not illustrated, the base 31 of the inner shoe is articulated relative to the upper 30 of this inner shoe around the two pivots, so as to allow limited flexion of the upper.

THE figures 8 and 9 illustrate two views of the sole 10 of the exogenous shell 1. As seen in the figure 8 , the sole 10 comprises a front plate 102 and a rear plate 103 which constitute replaceable wear parts fixed under the sole. Holes 100 through the sole 10 allowing water and snow which accumulates inside the exogenous shell to evacuate.

The internal face of the sole 10 is provided with a relief pattern, here constituted by ribs 101 separated by grooves and collaborating with corresponding grooves and ribs under the sole 37 of the inner shoe, in order to guarantee precise lateral positioning of the inner shoe 3 in the exogenous shell 1, and a transmission of forces between these two parts of the shoe. This construction also makes it possible to guarantee constant positioning of the internal shoe in the exogenous shell, even if the sole 37 wears out following walking; in fact the bottom of the grooves under the sole 37 is unlikely to wear, so that the vertical position of the internal shoe remains unchanged even if the ribs of the sole 37 wear.

The exogenous shell advantageously includes a largely perforated structure allowing the internal shoe to be seen. In one embodiment, the sole of the exogenous shell is composed of two parts welded, glued or mechanically assembled to each other; by varying the longitudinal fixing position, soles of different sizes can be produced from a single mold.
