Definitions

  • the invention relates to a shoe intended to cooperate with a vehicle by a pedaling action, and more particularly relates to cases where the vehicle is a vehicle.
  • a shoe according to the invention can be used with a bicycle, a scooter, a pedal car, an indoor training machine or any other machine that requires a pedaling action.
  • the shoe In the field of cycling, for example, the shoe cooperates with a pedal of the machine, namely here the bike, especially to advance it.
  • the shoe is brought, among other functions, to transmit forces or driving impulses, to transmit sensory information, or to restore reactions of the ground or the vehicle itself.
  • the prior art has proposed structures for the shoes of the field in question.
  • a cycling shoe comprises at least one sole and a shaft that define a boot volume, and often also includes a shim for the connection to the pedal.
  • a shim for the connection to the pedal.
  • the sole This includes a subdivision called outer sole.
  • the outer sole generally comprises one or more layers of materials that give it its mechanical properties, including flexural strength.
  • the upper generally includes a number of parts, such as a side section, a medial area, a vamp, a tongue, a heel, a rear buttress, a front end cap, a clamping device, an inner liner, or the like.
  • the shoe is obtained by assembling and putting in three dimensions pieces cut and assembled flat, that is to say in two dimensions.
  • the rod is associated, in known manner, with a mounting flange, to delimit a footwear element. According to a first method, the rod is glued to the mounting flange by a layer of glue.
  • the mounting flange also called the first mounting, is relatively rigid, to resist the mounting process.
  • the gluing is done by pulling the rod to press it on the first of assembly, knowing that a form is inserted in the stem. This is called traditional form fitting. This technique allows to exert sufficient pressure during the heating of the glue, to obtain the footwear element.
  • a second method also known, is to achieve the footwear element by joining the rod to the first mounting by means of a seam. This is called Strobel editing.
  • the first assembly is here a flexible sole, which can be sewn, called Strobel sole.
  • the first assembly is part of the assembly in the broad sense. In fact, the latter comprises at least the outer sole and the first mounting sole.
  • the shoe is formed by the combination of the footwear element with the constituent parts of the outer sole. This is to say that the shoe includes a sole and a rod.
  • a shoe according to the prior art is satisfactory, in the sense that it allows each user to properly drive his machine. Indeed, the user is able to transmit efforts or driving impulses, or to perceive sensory information, as well as reactions of the ground or the vehicle itself. However, it has nevertheless appeared that a shoe according to the prior art has some disadvantages.
  • EP 0 749 704 discloses a sandal comprising a sole, a flange connected to the sole and a connecting strip connected to the flange.
  • the invention generally seeks to improve a shoe intended to cooperate with a machine by a pedaling action. These include increasing the pedaling efficiency and / or reducing the fatigue of a user. This amounts to saying that the invention wants to improve the performance related to the use, for example during sports events. The invention also seeks to reduce the cost and duration of manufacture of a shoe, the underlying idea being to simplify the structure.
  • the invention proposes a shoe intended to cooperate with a machine by a pedaling action, the shoe comprising a base which extends in length from a rear end to a front end, in width between a lateral edge and a medial edge and in thickness between a face of cooperation with the machine and an inner face, the base having, from the rear end to the front end, a rear zone, a central zone, a metatarsal area and a front area, the shoe comprising a side wall and a medial wall.
  • the shoe according to the invention is characterized in that the side wall and the medial wall are directly secured to the base, and in that the base, the side wall and the medial wall are rigid subdivisions of the shoe.
  • the lateral and medial walls participate in the longitudinal flexural resistance of the shoe.
  • the walls in question oppose bending of the boot along a transverse axis thereof, the axis being parallel to the base.
  • the invention modifies the distribution of the forces induced by the longitudinal bending stresses, these efforts being localized with the invention significantly at the level of the lateral wall and at the level of the medial wall.
  • Another technical effect that results from the reduction of the thickness of the base is the reduction of the weight of the lower region of the shoe.
  • This region is lighter than the same region of a shoe according to the prior art and in the end, with the invention, the whole shoe is lighter. It can be said that the invention reduces the mechanical inertia of the shoe. A resulting benefit is, again, a reduction of user fatigue.
  • the shoe according to the invention has a simplified structure, compared to a shoe according to the prior art, in the sense that it is manufactured with a small number of parts. These include a reduction in manufacturing costs and a reduction in manufacturing time.
  • the invention improves a shoe intended to cooperate with a machine by a pedaling action.
  • the boot 1 comprises a base 3 which extends in length, in a longitudinal direction L, from a rear end 4 to a front end 5, in width, in a transverse direction W, between a lateral edge 6 and a medial edge 7, and in thickness between a cooperation face 8 with the machine and an inner face 9.
  • the cooperation face 8 can come into contact with the pedal 2 directly or indirectly.
  • the inner face 9, for its part can come into contact with the foot of the user directly or indirectly.
  • the base 3 has, from the rear end 4 to the front end 5, a rear zone 11, provided to come opposite the heel of the foot, a central zone 12 , planned to come next to the arch, a metatarsal area 13, intended to come opposite the metatarsal, and a front zone 14, provided to come next to the toes.
  • the shoe also includes a side wall 15 and a medial wall 16, which will be described in more detail later.
  • the side wall 15 and the medial wall 16 are directly secured to the base 3 and, respectively, the base 3, the side wall 15 and the medial wall 16 are rigid subdivisions of the shoe. It is specified in passing that a subdivision is a part of the shoe. This means that even if they can be flexible, the subdivisions can not be lengthened or shortened under usual conditions of use. It may be said in another way that these parts do not possess an elastic deformation property which would allow them to lengthen or shorten, and thus they can not form folds or wrinkle. Consequently, the base 3, the lateral wall 15 and the medial wall 16 delimit a rigid housing for receiving the foot.
  • the lateral and medial walls 16 participate in the longitudinal flexural resistance of the boot, at least at the junction with the base.
  • the walls in question oppose bending of the boot along a transverse axis thereof, the axis being parallel to the base.
  • the invention modifies the distribution of the forces induced by the longitudinal bending stresses, these efforts being localized with the invention significantly at the level of the lateral wall and at the level of the medial wall.
  • the side wall 15 is continuous along the entire length of the base 3, in the sense that it runs along the rear zone 11, the central zone 12, the metatarsal zone 13 and the front zone 14.
  • the medial wall 16 is continuous along the entire length of the base 3, in the sense that it runs along the rear zone 11, the central zone 12, the metatarsal zone 13 and the front zone 14.
  • the boot 1 comprises a rear wall 17 directly secured to the base 3 and a front wall 18 directly secured to the base 3, the rear walls 17 and before 18 being rigid subdivisions of the boot, the walls rear 17, lateral 15, before 18 and medial 16 forming a peripheral belt.
  • the rear wall 17 and the front wall 18 do not have any deformation property either. elastic that would allow them to lie down or shorten, and so they can not form folds or wrinkles. Consequently, in the end, it is the base 3, the rear wall 17, the side wall 15, the front wall 18 and the medial wall 16 which delimit the rigid housing for receiving the foot.
  • the assembly constituted by the base 3 and the walls 15, 16, 17, 18 delimits a rigid boot section in longitudinal flexion, and rigid also in torsion. This increases the ability of the shoe to transmit driving impulses, sensory information, ground or gear reactions, or the like.
  • the base 3 and each of the walls 15, 16, 17, 18 constitute a cradle-shaped piece whose structure is continuous.
  • each of the walls 15, 16, 17, 18 is an extension of the base in a direction away from the inner face 9.
  • This is the simplest structure, which has the advantage ease of manufacture, and a lower production cost due to the conformation in one part.
  • nothing, however, prevents, alternatively, to provide cases for which at least one or all walls are reported and made integral with the base, by any means such as a collage or any equivalent.
  • the rear wall 17 is strictly convex to the outside of the boot and, consequently, strictly concave inside the boot, that is to say facing the footwear volume.
  • the rear wall has a rounded surface which, on the outside, facilitates the unwinding of the foot when walking and which, inside, wraps and maintains the heel of the foot, in the manner of a bowl.
  • the front wall 18, meanwhile, is also strictly convex to the outside of the shoe and, consequently, strictly concave inside the shoe, opposite the footwear volume. It follows that the front wall has a rounded portion which, on the outside of the shoe, facilitates the unwinding of the foot when walking and which, inside the shoe, wraps the toes.
  • the walls 15, 16, 17, 18 has openings 21. These are all designated by the same reference for the sake of convenience.
  • the side wall 15 has several orifices
  • the medial wall 16 has several orifices. Some of these also extend at the level of the rear wall 17. It may optionally be provided to provide at the front wall 18. In all cases the orifices lighten the boot, and also allow aeration of the footwear volume.
  • This arrangement contributes, on the one hand, to the improvement of the performances because the removed material reduces the mechanical inertia and, on the other hand, to the improvement of the comfort by evacuation of a part of the moisture and / or heat generated by the foot.
  • This arrangement still allows a certain transverse flexibility to adapt to the contour of the foot during the clamping of the lateral and medial walls, as will be seen below.
  • the boot 1 has an upper opening 22 which extends opposite the rear zone 11, opposite the central zone 12 and partly at least opposite the metatarsal 13. This is to allow the passage of the foot to shoe or barefoot.
  • the shoe comprises a clamping device 23 of the lateral and medial walls 16. By its action, the clamping device 23 allows the foot to be held in the footwear during use of the boot.
  • the side wall 15 has a free end 25 and the medial wall 16 has a free end 26, ends which are urged towards one another by the clamping device 23 when the user actuates the latter.
  • the lateral and medial walls 16 are deformable in transverse flexion at their respective free ends, along the direction W.
  • the walls do not deform into transverse flexion at the base 3, because they are secured to the latter. Only the free ends 25, 26 of the walls can bend as only the end of a diving board can bend, if we want to present the phenomenon by comparison.
  • cases are provided for which the thickness of the side wall and / or the thickness of the medial wall is reduced from the base 3 towards the free end 25, 26.
  • the clamping device 23 comprises lateral loops 27, medial loops 28, a link 29 which travels through the loops and, optionally, a locking mechanism link, the mechanism is not represented here.
  • a passerby is an arrangement intended to guide the link, such as a hole in the mind of an eyelet, a hook, a clevis carrying a pulley, or any equivalent element.
  • the link meanwhile, can be a stretch of rope, cable, or other.
  • the base 3 and the walls 15, 16, 17, 18 are constituted here of fibers and / or portions of fibers joined together. by a matrix of synthetic material.
  • This combination of materials offers multiple possibilities for the development of the rigid housing that welcomes the foot.
  • the fibers and / or fiber portions are carbon.
  • This material makes the base and the walls, that is to say, the housing for the foot, both rigid and lightweight. As a result the shoe is well suited for sporty and intense use.
  • the matrix of synthetic material that is to say the material which serves as a fiber binder
  • the material which serves as a fiber binder is for example a thermosetting resin, a thermoformable material such as a polyurethane or the like, or any equivalent material.
  • the fibers as an alternative to carbon it is possible to use the glass, which is economical, the aramid, for its mechanical properties which represent in some cases an interesting alternative to the properties of carbon, or other.
  • the thicknesses of the base 3 and the walls 15, 16, 17, 18 are between 0.3 and 2 mm, knowing that values between 0 5 and 1 mm gave good results.
  • the piece constituted by the base and the walls is therefore thin, particularly at the level of the base, compared with the outer sole of a shoe according to the prior art. This is why the shoe according to the invention allows the foot to be closer to the axis of rotation of the pedal, which in particular results in an improvement in pedaling efficiency.
  • the benefits that result are reduced fatigue for a given effort, or improved performance during intense sporting events.
  • each wall 15, 16, 17, 18 is between 50 and 150% of the thickness of the base 3. This homogenizes the structure of the piece formed by the base and the walls.
  • An advantage that arises is a simple and easy manufacturing. Indeed, it suffices to apply one or more layers of fibers in a regular manner on a shape, that is to say an element whose geometry is similar to that of a foot, then to make the matrix rigid, for get the piece.
  • the base 3 and the walls 15, 16, 17, 18 are made of a plastics material.
  • the plastic material can be implemented by any known technique such as injection molding, three-dimensional printing by a specialized printer, cutting a block of material for example by means of a five-axis numerical control machine, or by any other suitable technique.
  • the injection of material has the advantage of rapid manufacturing.
  • Three-dimensional printing has the advantage of ease of evolution, in the sense that a simple modification of programming makes it possible to change the technical characteristics of the shoe. For example, it can be very simple to change the thickness of the base or wall. In all cases, the piece obtained is simple compared to what the prior art proposes because of its monobloc structure.
  • the thickness of the base 3 is between 1 and 6 mm, and the thickness of each wall 15, 16, 17 , 18 is between 1 and 3 mm. In some cases, it has already been said, the thickness of the walls is reduced to the free ends.
  • the values indicated are usual in the field of injection molding of plastics. They can also easily be obtained by implementing the other techniques mentioned above.
  • non-mandatory shoe 1 comprises a shim 31 disposed in the metatarsal area 13, the wedge being provided to cooperate with a pedal 2 of the machine.
  • the shim 31 comprises several elements, such as an inner plate 32, external fastening elements 33, 34, and screws 35 for securing the inner plate to the fastening elements through the base 3
  • the wedge 31 guarantees a precise support of the boot 1 with respect to the pedal 2. As a result, the driving efficiency is more constant.
  • the spacer 31 comprises at least one screw 35 whose head 36 is located on the side of the inner face 9 of the base 3.
  • the head 36 is located on the side of the face internal 9, for example taking place in the thickness of the inner plate 32. This reduces the size of the wedge 31 within the footwear volume, and thus the foot can stay as close to the pedal during driving the craft. We have already seen that this proximity is in the direction of a better pedaling performance.
  • the base 3 has a cavity 37 open on the side of the inner face 9.
  • This cavity accommodates the plate 32 of the wedge 31, as well as the heads 36 of the screws 35.
  • the plate and the heads of the screws are flush with the remainder of the inner face 9 of the base 3.
  • the plate 32 and the screws 35 do not protrude above the portion of the inner face 9 which circumvents the cavity 37. This allows the foot to take place in the shoe without any discomfort, for a better comfort of use.
  • the shoe 1 comprises a shoe 38.
  • the slipper is for example intended to provide a certain level of comfort to the user. It can be mounted in the boot 1 removably, which facilitates its change or temporary withdrawal, for example to access the screws 35. By this access it is possible to act on the screws, for example to loosen and then to tighten them, in order to adjust the position of the wedge 31 relative to the base 3. The access is even easier than the upper opening 22 of the shoe 1 extends to the metatarsal area 13 Because the plate 32 and the heads 36 of the screws 35 take place in the cavity 37, the establishment and removal of the liner are done freely without discomfort.
  • the cooperation face 8 has a convex curvature in the longitudinal direction and a convex curvature in the transverse direction.
  • the cooperation face 8 has a convex boss at the metatarsal area.
  • the base 3 is convex in all directions, on the side of the cooperation face 8, in the metatarsal area 13. This makes it possible to position the shoe 1 on the pedal 2 by movements with three degrees of freedom in rotation, in the spirit of a ball-type connection.
  • An advantage that arises is the ability to adjust the position of the shoe 1 on the pedal, in a manner that suits a majority of users, or all.
  • the cooperation face 8 has a spherical boss at the level of the metatarsal area.
  • the boss is circular in all directions, especially in the longitudinal direction and in the transverse direction.

  • the latter not reproduced, has a flat surface for the home of the shoe. It is simply an alternative embodiment that allows the use of a bike with flat pedals.
  • a spacer 41 is arranged facing the cooperation face 8. More specifically, the spacer is interposed between the base 3 and the 31, in the metatarsal area 13. This spacer protects the cooperation face 8 possible mechanical aggression, such as friction or punctures, which could occur for example when adjusting the position of the hold, when pressing the ground or on the pedal, or other.
