Definitions

  • the invention applies to the field of adjustment of shoes intended for sporting activities.
  • the invention relates to the means available to the athlete for adjusting the tightening tension of the upper part of the shoes around his foot and/or his leg.
  • these tightening means are essential on shoes intended for the practice of sliding sports (cross-country skiing, skating, snowboarding, etc.) and, in particular, on those used for alpine skiing and ski touring. , because the upper part of these shoes generally goes very high on the leg around the tibia and above the malleolus.
  • these tightening means are essential because, for reasons of comfort, the inner liner and its tongue are generally made of a flexible material (foam, etc.) and therefore elastically deformable. Consequently, it is necessary to compress this material under stress around the tibia in the front part of the leg to avoid the presence of too much play and to ensure effective transmission of the forces to the ski.
  • the patent FR2901970A1 describes such tightening means which comprise a strip of inextensible material surrounding the upper part or collar of the shoe and carrying an element for adjusting the tightening tension of the strip in the form of a hook-and-loop section.
  • the means for tightening this strap comprise a rear anchoring plate provided with flexible and elastic members (cable loops, rings, bellows, springs, etc.) ensuring the longitudinal connection with the two respective ends of the band , on either side of the rear plate.
  • the rear plate of the clamping means is here integral with the shoe and it is therefore not possible to move it laterally, nor to turn the band around the collar. Consequently, the teaching of this prior art is not satisfactory because it does not offer skiers the possibility of a fine and suitable adjustment of the tightening to their own morphology.
  • the invention aims to overcome the technical problems raised above by proposing an improved means of adjustment offering several degrees of adjustment of the tightening tension of the leg at the level of the upper part of the shoe as well as different orientations and adaptations of the support force of the shoe on the front of the leg.
  • the object of the invention is achieved by means of a tightening strap for a sliding sports shoe extending along the leg by an upper part, said strap comprising a band intended to surround the upper part to tighten the bottom of the leg, the said strap being formed of two longitudinal sections, and being retained on the upper part, characterized in that the strap is connected at the front to a central support element, the said central support element being free in translation in the extension of the two longitudinal sections of the strip to which it is connected by connecting elements ensuring, on either side, a double adjustment of the length of the strap.
  • the connecting elements consist of rings in which pass the ends of the longitudinal sections of the strip.
  • At least one of the rings is open to allow the separation of the corresponding section of the band.
  • the strip is fixed to the upper part and to the rear of the shoe.
  • the band is formed of two independent sections fixed to the rear of this upper part.
  • the ends of the two longitudinal sections of the strip are free and each provided with a loop hooking member on itself around the connecting elements.
  • this attachment member consists of a portion of hook-and-loop tape secured to the strip.
  • the connecting elements are elastically deformable.
  • the central support element may be, at least partially, elastically deformable.
  • the band is made with an inextensible textile material.
  • Another object of the invention is a ski boot, characterized in that it is equipped with a tightening strap as defined above.
  • the upper part of this shoe forms a collar.
  • the support element is centered on the front.
  • the support element is interchangeable.
  • the support element has at least one projecting part so as to provide differentiated support on different areas of the shoe.
  • the strap of the invention offers the possibility of double adjustment of the length of the band, which makes it possible to obtain a stronger tension and therefore a firmer and more precise tightening of the leg above the malleolus.
  • the strap of the invention allows the translational movement of the central support element on the front of the shoe.
  • the profile of the leg varies according to the individuals whereas the shells of shoes are generally manufactured with standardized shapes.
  • a slight lateral off-centering of the support element, inwards or outwards makes it possible to adapt the tightening as close as possible to the skier's leg according to his own morphology. .
  • the invention relates to the field of adjusting and tightening sports shoes and, in particular, shoes intended for sliding sports such as alpine skiing, ski touring, cross-country skiing, snowboarding or else still skating.
  • the boots intended for these sporting activities generally comprise a rigid outer shell which, in particular for the practice of alpine skiing, contains an inner shoe, which is generally removable.
  • the inner shoe can be made of a flexible and deformable material, and the latter generally has a tongue projecting upwards in its front part.
  • These shoes comprise, in the lower part, a lower shell in which the foot is housed and which is extended, in the upper part, by a collar which surrounds the lower part of the leg and which immobilizes it and wedges it relative to the shoe .
  • these shoes are equipped with a strap intended to eliminate, or at least to reduce, the play which does not fail to appear, after putting the foot in the shoe, in the zone between the tibia above the malleoli and the collar M of the shoe C.
  • the tightening tension is adjusted by adjusting the length of this strap around the collar.
  • the strap comprises a strip 1 of textile material retained on the rear of the collar M and connected at the front to a central element 3 exerting a bearing force against the tibia via the wall of the collar M.
  • the strip 1 consists at least two longitudinal sections 1a, 1b.
  • the webbing material is usually inelastic or inextensible.
  • the strap could have at least partially a certain degree of elasticity, or even an alternation of inelastic portion and elastic portions.
  • the strap of the invention aims to improve the tightening by offering several degrees of adjustment of the tightening tension of the leg inside the collar M of the shoe C as well as by allowing different orientations and adaptations of the force of support of the shoe on the front of the leg.
  • the central support element 3 of the improved strap according to the invention is free in translation in the extension of the two longitudinal sections 1a, 1b of the strip 1.
  • the central support element 3 is connected to the two longitudinal sections 1a, 1b of the strip 1 by connecting elements 2a, 2b, allowing, on either side and in cooperation with the ends of the sections 1a, 1b, a double adjustment of the length of the strap.
  • the connecting elements 2a, 2b consist of rings through which pass, respectively, the ends of the longitudinal sections 1a, 1b of the strip 1.
  • the rings 2a, 2b and, preferably, the two rings are in an open loop to allow, if necessary, the separation of the corresponding sections 1a, 1b of the band 1.
  • the connecting elements 2a, 2b are elastically deformable.
  • the support element 3 is interchangeable. It is then possible to replace, for example, in the event of wear or change of decor, a central support element by another support element.
  • This other element may also have different characteristics, in particular dimensional (length, height, thickness), material (rigidity, elasticity, hardness, etc.).
  • the central support element 3 is in the form of a plate, the width of which corresponds substantially to that of the strip 1.
  • the face of the element 3 which is turned towards the the front or the outside can present any information and, in particular, the brand of the shoe C.
  • the rear or internal face can present a zone where the personal information of the user is presented.
  • the support element 3 can be made of a flexible material.
  • the material used may be a textile material, a foam, or even a plastic material.
  • the element 3 can be made of inelastic material, or alternatively at least partially made with an elastically deformable material.
  • element 3 could have a width greater than that of the strap, to increase the bearing surface on the front of the shoe and the leg, or on the contrary, have a width less than the width of the strap , to reduce its weight or reduce the tightening pressure on the front of the leg.
  • the element 3 may have a thickness greater than the thickness of the sections of the strap, or alternatively, a lesser thickness.
  • the element 3 is flat in shape, but it could, without departing from the scope of the invention, have at least one projecting part, thus with a different thickness along its length or along its height. Indeed, in some cases, it may be judicious to provide support for the strap and the central element both on the tongue of the inner shoe, and on the outer shell, possibly in a differentiated manner.
  • part of the element 3 can rest on the tongue of the liner, or more generally on the liner, and another part of the element 3 can rest on the upper part of the shell.
  • the strip 1 is made in a single continuous piece of inextensible textile material. As illustrated by the figure 1B , the band 1 is fixed on the collar M at the back of the shoe C, for example, by means of a screw or a rivet 4.
  • the band 1 can slide freely in a loop or a trigger guard carried by the shell at the rear of the shoe C.
  • a similar strap retaining system could also be envisaged on one side of the hull, replacing or in addition to the rear restraint system.
  • the band 1 could also be formed of two independent sections fixed together on the collar M at the same point of its rear part or at two distinct points.
  • the ends of the longitudinal sections 1a, 1b of the strip 1 are free and each provided with a member 10a, 10b for hooking in a loop on itself around the rings 2a, 2b forming the connecting elements.
  • This attachment member 10a, 10b preferably consists of a portion of self-gripping tape (of the Velcro type, registered trademark) secured to the strip.
  • the strap of the invention is designed to allow the movement in translation of the central support element 3 on the front of the shoe, as illustrated by the figures 2A and 2B .
  • the anatomical profile of the leg varies according to the individuals whereas the hulls of the shoes are generally manufactured with standardized shapes.
  • the morphology of the leg is particular in that the leg is not symmetrical, in particular on its front face. Indeed, as seen in the figure 4 , on its front face, a right leg will present, laterally towards the exterior, a set of muscles S, and laterally towards the interior, the bone T of the tibia (and symmetrically for the left leg). This arrangement of muscles and bones on the front of the leg is all the more important as each skier is physically different. Also, the strap according to the invention makes it possible to adapt the tightening of the upper part of the boot, according to the wishes of the skier, to tighten and press more on the muscular parts S, or on the contrary on the bone T of the tibia and thus optimize, if necessary, the transmission of forces.
  • a lateral off-centering of the support element 3, towards the outside (as on the shoe for the right foot represented on the figures 2A and 2B ) or, alternatively, towards the inside, makes it possible to adapt the tightening as close as possible to the skier's leg according to his own morphology.
  • the off-centering of the support element can be of the order of one to about ten centimeters, in the longitudinal direction, or in the direction of the length of the strap.
  • This off-centering is obtained by first opening the attachment members 10a, 10b and releasing in the rings 2a, 2b a determined length of strip on one of the longitudinal sections (the section 1b on the figure 2A ) while shortening the other (section 1a, figure 2A ) then by re-locking the fastening devices under tension of strip 1.
