Definitions

  • the invention relates to a lower shell for a gliding shoe.
  • the invention also relates to a gliding boot, in particular a ski boot comprising such a lower shell and a collar articulated around the lower shell.
  • Sliding sports are sports in which a user guides one or more sliding boards attached to their feet. For the practice of these sports, the variations of the ground are felt at the level of the feet and the bottom of the legs through sliding shoes.
  • Sliding shoes conventionally comprise a lower shell enveloping the foot of the user and a collar enveloping the lower leg. The collar is articulated in rotation around the bottom of the shell along an axis of rotation substantially aligned with an axis passing through the malleoli of the user.
  • Sliding shoes play an essential role in the user's perception of the terrain and in the impulses he transmits to the gliding board(s).
  • alpine skiing is a sport in which a user guides a pair of skis attached to his feet on a snowy terrain.
  • a skier links turns he alternates phases of flexion and extension of the legs.
  • the collar pivots forward relative to the bottom of the shell and during the extension phases, it pivots rearward.
  • characteristics of support but also of elasticity, cushioning and rebound of the ski boots are sought after in order to obtain ski guidance that is dynamic, precise and without superfluous effort.
  • the rebound of a ski boot characterizes its ability to return to its initial position, following forward bending of the cuff.
  • Manufacturers seek to increase the rebound of sliding shoes.
  • gliding shoes comprising an elastic strap able to produce a substantially constant pressure on the user's tibia. This pressure makes it possible to maintain a substantially constant tibial support on the gliding boot during the movement of flexion/extension of the legs and thus makes it possible to achieve better control of the skis.
  • the rebound obtained with such gliding boots is still insufficient.
  • sliding shoes must also remain simple to use and manufacture.
  • the gliding boots known from the state of the art do not make it possible to achieve all of these requirements at the same time.
  • the shoes known from the state of the art do not make it possible to guide one or more gliding boards in a sufficiently dynamic, efficient and precise manner.
  • the object of the invention is to provide a gliding shoe remedying the above drawbacks and improving the gliding shoes known from the prior art.
  • an object of the invention is a gliding shoe that is simple to manufacture and offers optimal rebound characteristics for guiding one or more gliding boards.
  • the invention relates to a lower shell for a sliding shoe comprising an enveloping part intended to receive a foot of a user and a one-piece tongue with the enveloping part extending substantially from a rear wall of the enveloping part and towards the top, the tab being intended to cooperate with a collar articulated in rotation around the enveloping part.
  • the enveloping part can extend up to above the malleoli of a user, and the tongue can be connected to the enveloping part substantially at the level of the malleoli.
  • the tongue may comprise at least one stiffening rib whose thickness decreases as the tongue is traversed from bottom to top.
  • the tab may extend above the wraparound portion.
  • the bottom of the hull can be obtained by plastic injection, in particular by polyurethane injection.
  • the tongue may comprise a generally rectangular shape, a height of the tongue being between 5 cm and 20 cm, and/or a width of the tongue being between 5 mm and 30 mm.
  • the bottom of the shell may include a space defined between the rear wall of the enveloping part and the tongue, a dimension of this space being between 2 mm and 15 mm.
  • the tongue can be globally inclined forwards by an angle comprised between 5° and 20° relative to a vertical axis.
  • the tab can be configured to flex as the collar pivots forward about the wraparound portion.
  • the invention also relates to a gliding shoe comprising a bottom as defined above, the collar being articulated in rotation around the enveloping part, the tongue being linked to the collar.
  • the collar may include a back wall covered by the tab.
  • the collar may include an opening into which an upper end of the tab is inserted.
  • the tongue can be fixed to the collar, in particular by means of at least one fixing screw.
  • the tab may comprise an upper portion covered by a wall of the collar and a lower portion not covered by the collar.
  • the invention also relates to a collar for a gliding shoe comprising an enveloping part intended to receive a lower leg of a user and a one-piece tongue with the enveloping part extending substantially from a rear wall of the enveloping part and towards the bottom, the tongue being intended to cooperate with a bottom of the shell articulated in rotation around the enveloping part.
  • the figure 1 schematically illustrates a sliding shoe 1 according to one embodiment of the invention.
  • the gliding boot is a ski boot, in particular for alpine skiing.
  • the shoe could be any shoe intended for use in any other sliding sport, that is to say a sport where a user guides one or more sliding boards with his feet, by performing movements of flexion and leg extension.
  • the gliding boot may be any other snow gliding boot, naming a snowboard boot, a ski touring boot, or a cross-country ski boot.
  • a longitudinal axis X is defined as being an axis parallel to the axis in which the user's foot extends from the heel (at the back) towards the toes (at the front).
  • the transverse axis Y designates an axis perpendicular to the longitudinal axis X and passing through the two malleolus of the user.
  • the X and Y axes are horizontal.
  • the vertical Z axis is an axis perpendicular to the X and Y axes.
  • the front and the back are defined in relation to the longitudinal X axis: the front designates an area more towards the toes while the back designates a zone more towards the heel.
  • Top and bottom are defined in relation to the vertical Z axis.
  • An upper zone denotes an area further up and a lower zone denotes an area further down.
  • the gliding shoe 1 comprises a lower shell 2 comprising an enveloping part 3 intended to receive, or in other words to envelop, the foot of the user.
  • the gliding shoe 1 also includes a collar 4 intended to envelop the lower leg of the user.
  • the collar is articulated in rotation around the bottom of the shell, and in particular around the enveloping part 3, along an axis Y1 substantially parallel to the transverse axis Y and passing through the user's two malleolus.
  • the enveloping part 3 comprises a general shape which matches the shape of the foot. It includes in particular a rear wall 5 which matches the shape of the heel and the Achilles tendon. It also includes domed side walls that follow the shape of the malleolus.
  • the rear wall extends vertically over the entire height of the bottom of the shell and laterally substantially up to the level of the malleolus. As can be seen on the figure 6 , this rear wall 5 may comprise a portion that is generally inclined forwards, in order to promote bearing of the user's tibia on an opposite surface of the shoe, that is to say on a front surface of the shoe, in particular a front surface of the collar.
  • the bottom of the shell 2 can also include attachment interfaces intended to cooperate with a device for attaching a gliding board.
  • the gliding shoe being a ski boot, it comprises a front curb 6A and a rear curb 6B intended to cooperate with the jaws of a binding device.
  • the curbs form at least part of the sole of the shoe.
  • the enveloping part 3 which is clearly visible also on the figure 4 and 6 , extends upwards to above the malleolus. It comprises an upper opening 7 allowing the insertion of the foot inside the lower shell. This upper opening 7 is extended on top of the foot by a longitudinal opening 8 which can be closed by means of closing devices (not shown), such as for example one or more tightening buckles. Two side flaps, positioned on either side of the longitudinal opening 8 can thus be superimposed on the top of the foot, in particular in order to guarantee the tightness of the gliding shoe.
  • Collar 4 clearly visible on the picture 3 , has a generally tubular shape. It comprises two side flaps 9 intended to overlap at the front of the lower leg, substantially at the level of the tibia.
  • the collar 4 may also include closure means capable of blocking the two side flaps 9 to enclose the lower leg, for example one or more tightening buckles.
  • the collar 4 extends downwards substantially up to the height of the malleoli, and it extends upwards substantially up to mid-height of the tibia or up to a third of the height of the tibia.
  • the rotational connection between the collar and the bottom of the shell can be achieved by means of axes extending parallel to the axis Y1. These axes are capable of cooperating with openings made in the walls of the bottom of the shell 2 and of the collar 4, at the level of each of the malleolus of the user.
  • the collar and the bottom of the shell can preferably be made of plastic, in particular of injected plastic.
  • they may be in polyurethane.
  • the collar and the bottom of the shell can be made from the same plastic material.
  • the plastic material and the thickness of the walls forming the collar and the bottom of the shell are chosen so as to protect the foot and so as to give the gliding shoe a rigidity suited to the practice of the gliding sport concerned.
  • any other material can be envisaged to form the bottom of the shell and/or the collar.
  • the plastic material may be filled, in particular with glass or carbon fibers.
  • the collar and/or the bottom of the shell can be formed by an assembly of several materials, obtained for example by over-injection, bi-injection or else co-injection.
  • the material constituting the collar and the bottom of the shell is not a foam (that is to say a material filled with air or gas bubbles).
  • the plastic material comprises a flexural modulus comprised between 100 and 500 Mpa, preferably comprised between 100 and 300 Mpa.
  • the gliding shoe may also include a comfort liner (not shown) inserted inside the lower shell and the collar.
  • the comfort liner makes it possible to avoid direct contact between the user's foot or lower leg on the one hand and the bottom of the shell and the collar on the other hand.
  • the bottom of the shell 2 comprises a tongue 10 made in one piece with the enveloping part 3.
  • the term "one-piece" means that the tongue 10 and the enveloping part 3 form a single and same piece.
  • the tongue 10 and the enveloping part therefore form a monolithic assembly, as opposed to an assembly formed by the assembly of two separate parts.
  • the enveloping part and the tongue can be obtained during the same injection operation. Maintaining the tongue on the enveloping part is obtained thanks to the cohesion of the plastic material.
  • the tongue 10 is connected to the rear wall 5 of the enveloping part 3 via a lower end 11 of the tongue 10.
  • the tongue therefore extends substantially to the rear of the bottom of the shell 2.
  • the connection between the tongue and the bottom of the shell is positioned substantially at mid-height of the enveloping part 3.
  • the tongue is connected to the enveloping part substantially at the height of the malleoli, in particular at the height of the axis of articulation between the bottom of hull and collar.
  • the connection between the tongue 10 and the enveloping part 3 is positioned substantially in the center of the rear wall 5, equidistant from the two malleolus.
  • the connection between the tongue 10 and the enveloping part 3 is positioned substantially opposite the user's Achilles tendon.
  • the tongue is arranged outside the enveloping part 3 and is thus not intended to come into contact with the foot of the user or with a boot inserted into the enveloping part. As we will see later, the tongue is intended to cooperate with the collar 4, in particular via its upper end 12.
  • the tab 10 which could also be called a "blade” or an “appendage", extends substantially from the rear wall 5 of the enveloping part 3 and upwards. It extends substantially parallel to the rear wall 5, and therefore mainly parallel to the vertical axis Z.
  • a space 13 can thus be defined between the rear wall 5 of the enveloping part and the tongue 10.
  • a dimension of this space 13 that is to say the distance separating the tab 10 from the rear wall 5, can for example be between 2 mm and 15 mm.
  • This space 13 may be substantially constant over the height of the tongue 10 facing the rear wall 5.
  • the tongue 10 may not extend perfectly vertically.
  • it can be generally inclined forwards by an angle A1 of between 5° and 20° relative to the vertical axis Z.
  • the tongue 10 extends upwards above the enveloping part 3 in order to cooperate with the collar 4.
  • the upper end 12 of the tongue is therefore positioned above the upper opening 7 of the enveloping part 3
  • the tab comprises a generally rectangular shape.
  • a height H of the tongue, measured along its main direction of extension, can be between 5 cm and 20 cm.
  • a width L of the tab, measured along the transverse axis Y, can be between 5 mm and 30 mm.
  • the rear tab could be generally trapezoidal in shape, in particular wider at its lower end 11 than at its upper end 12.
  • the tongue 10 is intended to cooperate with the collar to produce a return force of the collar with respect to the enveloping part 3.
  • the tongue thus makes it possible to modify the rebound characteristics of the shoe. More specifically, the tongue is linked to the collar so as to flex when the collar pivots forward relative to the enveloping part.
  • the tongue comprises mechanical characteristics such that it generates a return force on the collar, tending to bring the collar back into the vertical position, as opposed to a position more inclined forwards.
  • the tongue 10 thus makes it possible to improve the rebound characteristics of the shoe. It is therefore understood that the tongue is an elastic tongue. It is capable of withstanding a bending whose amplitude is determined by the amplitude of bending of the collar around the bottom of the shell, without breaking or without undergoing permanent deformation.
  • the tongue 10 comprises a stiffening rib 14 which can extend over the entire height of the tongue.
  • the rib 14 is arranged vertically in the center of the tab and projects rearward.
  • the rib has a decreasing thickness by traversing the tongue from bottom to top.
  • Such a rib shape gives the tongue bending properties leading to get excellent rebound from the shoe.
  • the rebound characteristics of the shoe may be modified by adapting the dimensions of the tongue, in particular its length, and/or its thickness and/or the dimensions of the stiffening rib, and/or its anchor point on a wall of the hull bottom.
  • the decreasing profile of the stiffening rib can also be modified in order to modify the behavior of the boot.
  • the tongue is fixed to the collar 4.
  • the fixing of the tongue to the collar is carried out by means of a fixing screw 15 passing through a hole provided at the level of the upper end 12 of the tongue, and a hole 16 provided at the back of the collar.
  • the fixing screw 15 cooperates with a connecting piece 22, such as a nut, positioned from inside the collar.
  • the connecting piece 22 may comprise a tubular part positioned through the holes provided in the tongue and in the collar as well as a thread capable of cooperating with the fixing screw 15.
  • the tubular part makes it possible to avoid direct contact between the thread of the fixing screw and the edges of the holes provided in the tongue and in the collar.
  • the fixing screw extends substantially parallel to the longitudinal axis X.
  • the collar further comprises a rear wall 17 covered by the tongue 10.
  • This rear wall 17 has a substantially planar shape and is positioned inside the space 13 defined between the rear wall 5 of the enveloping part 3 and the tongue 10.
  • the rear wall 17 of the collar therefore covers the rear wall 5 of the enveloping part, which forms a chicane making it possible to prevent snow from entering the shoe.
  • the collar also includes an opening 18 into which the upper end 12 of the tab 10 is inserted.
  • the opening 18 is positioned above the rear wall 17 and below the hole 16.
  • An upper portion 20 of the tongue is thus covered by a second rear wall 19 of the collar surmounting the first rear wall 17.
  • the space between the two walls 17 and 19 forms a housing for receiving the upper end 12 of the tongue.
  • the ski boot it is possible to manufacture, on the one hand, by plastic injection, in one and the same piece, a lower shell comprising the enveloping part and the tongue.
  • the collar can also be manufactured by plastic injection. The lower shell and the collar are then assembled together: the end of the tongue is inserted into the opening 18, then the rotational joint of the collar is installed around the lower shell and secured the tab to the collar via hole 16.
  • the user When using the shoe, for example for downhill skiing, the user alternates movements of flexion and extension of the legs.
  • the collar tilts forward in relation to the enveloping part by pivoting around the Y1 axis. This pivoting causes the tongue 10 to bend.
  • the elasticity of the tongue produces a force which tends to oppose the pivoting of the collar forwards.
  • the collar returns to the rear, in a more upright position.
  • the force produced by the tongue facilitates this return to position and relieves the user.
  • the user's muscles are less stressed during the leg extension phase, which allows better preparation for the following flexion phase.
  • the return force produced by the tongue makes it possible to maintain tibial support on the collar throughout the movement of flexion and extension of the leg, necessary for the correct guidance of the gliding boards.
  • the user thus benefits from an improved rebound effect compared with the use of conventional ski boots.
  • the boot thus allows ski guidance to be dynamic, precise and effortless.
  • the rebound of a shoe can be characterized by a laboratory test in which the shoe is blocked by its lower shell, positioned flat on the ground, then the cuff is pulled forward. Then the collar is released and naturally returns to its initial position.
  • An accelerometer is installed to measure the acceleration of the backward stroke of the collar. The rebound can then be quantified as a function of the measured acceleration. Tests carried out on a shoe according to the invention show that the rebound can be improved by approximately 40% compared with an identical shoe without a tongue.
  • the tongue is not necessarily linked to the collar by an embedding type link.
  • the tongue could be linked to the collar according to a sliding link. It can for example be simply inserted into the opening 18 and free to slide inside this opening parallel to the direction in which the tab extends.
  • the tongue comes into contact with the rear wall 19 of the collar.
  • the wall 19 of the collar on the tongue By reaction of the wall 19 of the collar on the tongue, the latter produces a rearward return force tending to straighten the collar.
  • the tab can be attached to the collar in different ways; for example by means of a single screw as has been described or by means of several screws.
  • the tongue can comprise several holes capable of cooperating with one or more screws to define a more or less pronounced inclination of the collar with respect to the bottom of the shell.
  • the fixing screw 15 can be replaced by any equivalent fixing means, in particular a rivet, a pin or a clip.
  • the tongue 10 could also be welded or glued to the collar.
  • the fixing means making it possible to fix the tongue to the collar can be arranged so as to be invisible from the outside of the shoe.
  • the hole 16 is arranged in the rear wall 17 of the collar and is extended by a blind hole in the second rear wall 19 of the collar. The hole 16 is therefore not opening onto the outer face of the collar.
  • the fixing means comprises a lug 23 passing through the hole 16 and the hole provided in the tongue, as well as a head 24 arranged on the side of the rear wall 17 of the collar.
  • a counterbore can be provided on the internal face of the wall 17 to accommodate the head 24 so as not to generate a protuberance on the surface of the wall 17.
  • the fixing means can be fixed to the rear wall 17 of the collar by example by screwing.
  • the lug 23, crossing the hole of the tongue 10 retains this tongue 10 so as to block it when the shoe flexes forward.
  • the bottom of the hull can be made entirely of injected plastic material.
  • it may also include inserts, in particular metal inserts intended to stiffen certain parts of the bottom of the hull.
  • a metal insert can for example be provided inside the tongue to increase its rigidity.
  • the bottom of the shell can also be formed by combining different plastic materials, for example by means of co-injection, over-injection or plastic bi-injection processes.
  • the shoe may further comprise, in addition, means for adjusting the flex, that is to say means for adjusting the resistance to bending of the shoe forwards.
  • adjustment means can be obtained by means of fixing screws passing through the enveloping part and the collar, in particular at the level of the rear walls 5 and 17.
  • the shoe previously described comprises a single tongue extending from the rear of the shoe.
  • it could include several similar tabs.
  • the shoe could for example comprise two tongues positioned on either side of a longitudinal median plane of the shoe, each of these tongues being connected to the collar.
  • the tongue(s) extend generally upwards so as to connect the enveloping part to the collar which surmounts it. By “upwards” it is understood that the tongue can be oriented in any direction making it possible to ensure the connection between the enveloping part and the collar.
  • the tab(s) may be more or less inclined with respect to the vertical axis.
  • the tongue(s) can be inclined up to an angle of approximately 30° relative to the vertical axis, or even up to an angle of approximately 45° relative to the vertical axis.
  • the tongue could not form a one-piece assembly with the enveloping part but with the collar.
  • the tongue would extend mainly downwards from the collar and would cooperate with the bottom of the shell to flex following a forward rotation of the collar.
  • the tongue would then possibly be fixed to the bottom of the shell and/or inserted via its lower end into an opening provided in the bottom of the shell.
