Definitions
- the present invention relates to a monolithic cycling shoe sole intended to cooperate with a cycling pedal provided with an attachment device, called an automatic pedal.
- the automatic pedal makes it possible to create a detachable mechanical connection with the shoe in order to efficiently transmit the force of the shoe to the automatic pedal, in particular in the upward phases of the pedaling cycle.
- a wedge fixed under the sole and comprising connecting means allows the shoe to hook and unhook from the automatic pedal. This cleat is therefore an interface part between the automatic pedal and the shoe.
- Said monolithic sole is made of plastic or a composite material and offers great rigidity so that its deformation under the action of pedaling is as low as possible.
- the monolithic sole according to the invention can be used with all devices requiring pedaling action but it is particularly suitable for road cycling, cycling on gravel tracks and cycle touring.
- Pedals, cleats and shoes, for road cycling and mountain biking are different on several characteristics and have different advantages and disadvantages:
- the automatic road pedals are equipped with a single attachment device and are designed to have a large surface in contact with the cleat so that pedaling forces are transmitted and distributed as well as possible.
- the cleats for automatic road pedals are generally made of plastic and of large size, comprise a front connection means and a rear connection means making it possible to hook onto the pedal and include protuberances called “tread stud” which protect said connecting means during the walking phases. They are fixed under the sole of the shoe generally by three screws.
- Road cycling shoes have plastic or composite material soles to be as rigid as possible in order to best transmit the pedaling forces from the shoe to the pedal. They are light and do not have crampons because the thickness of the wedge attached to the sole is such that contact with the ground during the walking phases is made on the "tread blocks" of the wedge.
- MTB automatic pedals have an attachment device on each of its faces to facilitate the operation of hooking the boot in steep terrain where the user, in unstable balance, often has very little power. time to hang the shoe on the pedal. They have a very small contact surface with the cleat in order to allow the shoe to be hooked up even when the sole, cleat or pedal is clogged with impurities (mud, stones, leaves, etc.).
- MTB cleats are generally metallic, small in size, thin, and are secured under the sole of the shoe, usually with two screws.
- MTB shoes have soles of less rigidity than road shoes and have the underside covered with a non-slip and abrasion resistant coating on almost the entire surface. A recess is present in said non-slip coating where the wedge is housed in the depth of said recess so that it does not touch the ground during the walking phases.
- MTB shoes can overcome this disadvantage because they allow easy walking, but their lack of rigidity and the cleats used do not achieve as good transmission of pedaling efforts and as good comfort as road shoes.
- Patent No. FR3016153B1 provides a solution to the problem posed with an assembly consisting of a shoe and a specific two-part cleat.
- This solution consists of the sole of the shoe being made flexible over its entire width in the metatarsal area, between the front attachment means and the rear attachment means of the cleat.
- the cleat is split into two distinct pieces: a front cleat and a rear cleat so that the flexible area of the sole can maintain freedom of flexion.
- the front and rear wedges are embedded in the studs of the sole so as not to protrude so that the wedges do not touch the ground when walking.
- the advantage of this solution is that the unrolling of the shoe is close to a shoe dedicated to walking, which answers the problem.
- this solution has the following drawbacks:
- the shoe equipped with such a sole is less rigid than a conventional road shoe comprising a rigid monolithic sole, so it is less efficient in transmitting the forces during the pedaling phases.
- the monolithic cycling shoe sole according to the invention makes it possible to provide a solution to the problem posed by walking with conventional cycling shoes because the wedge does not protrude from the underside of said monolithic sole. Walking is therefore comfortable and secure, and the stiffness and weight remain the same as current road cycling shoes.
- the shoe equipped with the monolithic sole according to the invention thus retains good performance and comfort characteristics during the pedaling phases.
- this object is achieved by an assembly composed of a rigid monolithic sole made of plastic or of a composite material of a cycling shoe, of a front cleat comprising a front connection means capable of cooperating with a device for 'front attachment of an automatic pedal and a rear cleat comprising a rear connection means capable of cooperating with a rear attachment device of said automatic pedal, said cleats being fixed to the underside of said monolithic sole.
- the monolithic sole comprises on its underside a front hollow situated between the front end of the sole and the zone of contact with the automatic pedal and substantially in the middle of the width of said monolithic sole; and a rear hollow positioned substantially in the middle of the length and the width of said monolithic sole and opening onto at least one of the lateral sides of said monolithic sole; said front and rear hollows are dimensioned to receive respectively the front and rear attachment device of said automatic pedal and to respectively receive the front and rear cleat so that they are fully integrated into the depth of said front and rear hollows.
- the front wedge is positioned in contact with the rear edge of the front hollow, and the connecting means of said front wedge is oriented towards the front of the monolithic sole;
- the rear wedge is positioned in contact with the front edge of the rear hollow, and the connecting means of said rear wedge is oriented towards the rear of the monolithic sole;
- the front hollow and the rear hollow each comprise at least one hole passing through the thickness of the monolithic sole, said hole being able to cooperate with the fixing element of the front and rear wedges;
- the front edge of the rear hollow comprises a protrusion projecting into said rear hollow, located between the rear wedge and the lateral side of the monolithic sole where the rear hollow opens, said protuberance being able to push back the rear attachment device of the automatic pedal towards the rear of the monolithic sole during a phase of unhooking the shoe;
- the distance between the rear edge and the front edge of the front hollow is dimensioned to allow the passage of the front attachment device of the automatic pedal during the hooking phase of the shoe in said pedal;
- the distance between the lateral edges of the front hollow is greater on the front side of the monolithic sole than that on the rear side of said monolithic sole;
- the underside of the monolithic sole is covered with an adherent and abrasion resistant coating except for the front hollow, the rear hollow and the area in contact with the automatic pedal during the phases of pedaling, hooking up and unhooking the shoe.
- the front hollow opens onto the front end of the sole.
- the sole has two side walls, a front wall covering the toes and a rear wall covering the heel, the whole being in one piece.
- the subject of the invention is also a kit which facilitates the transmission of forces between the foot and the pedal during the pedaling phases.

- the area (9), located in the metatarsal region, between the front and rear hollows (6,7), is smooth and dedicated to direct contact with the upper face of the automatic pedal (3) in order to directly transmit the forces of the shoe (1) to the automatic pedal (3), thus increasing the performance during the pedaling phases.
- the other advantage of this direct contact is that the distance between the monolithic sole (2) and the automatic pedal (3) is consequently zero, which is a characteristic (called "bio position") sought to increase pedaling performance. .
- the front wedge (4) is positioned in contact with the rear edge (12) of the front hollow (6) and oriented with the front connecting means (14) towards the front of the monolithic sole (2).

- the protrusion (8) is integrated into the rear wedge (5), the rear connecting means (15) and the protrusion (8) then forming a single piece.
- the rear hollow does not open out and stops near the internal lateral side of the monolithic sole (2), the distance between the two lateral edges of the rear hollow (7) is such as to allow the boot to be released.
- the front hollow (6) opens onto the front end of the sole.
- the monolithic sole (2) according to the invention comprises two side walls (20), a front wall (21) completely or partially covering the toes and a rear wall (22) covering. in whole or in part the heel, the whole being in one piece.
- the invention described is particularly well suited to the practice of sport cycling on roads and on gravel paths, including cycle tourism.
- the sole, the assembly and the shoe possibly in association with the automatic pedal are mainly intended for road or "gravel" cycling.
- the sole must be rigid in order to transmit the cyclist's efforts on the pedals as efficiently as possible.
- the sole is therefore more rigid than the equivalent sole found in mountain biking or mountain biking with the exception of "cross-country” shoes.
- the sole has a lower face intended to bear on an upper face of the pedal.
- the sole has an upper face intended to receive the cyclist's foot and opposite the lower face.
- the upper side can be covered with one or more layers of comfort.
- the sole also has opposing inner and outer faces.
- the sole defines a first so-called front hollow cavity 6 which is intended to receive a front wedge 4.
- the sole defines a second so-called rear hollow cavity 7 which is intended to receive a rear wedge 5.
- the front wedge 4 and the rear wedge 5 can be made of metal or polymer material or composite material.
- the bearing surface on the pedal is formed by the sole.
- the metatarsal zone 9 of the cleat bears against the upper surface of the pedal so as to form a contact zone ensuring good power transfer.
- the curvature of the sole is particularly advantageous for the curvature of the sole to be identical or substantially identical to that of the upper face of the pedal in order to have an extended contact zone between the sole and the pedal and thus facilitate the transmission of forces.
- the metatarsal area 9 of the sole is located between the front hollow 6 and the rear hollow 7.
- the metatarsal area is preferably devoid of any fixing means, and for example of the nuts that are conventionally encountered in the soles of the art. prior. It is then possible to form a metatarsal zone whose thickness is less than in the prior art, for example less than 4mm, preferably less than 2mm.
- the front hollow 6 and the rear hollow 7 are separated by the metatarsal zone 9 of the sole intended to come into vis-à-vis the metatarsals. of the foot of a user, the metatarsal zone forming the contact zone 9 with the automatic pedal 3.
- the metatarsal zone is devoid of fixing element 16 of the front cleat 6 and of the rear cleat 7, the zone thickness metatarsal being less than or equal to 4mm.
- the metatarsal zone is formed by a constant thickness.
- first cavity or front hollow 6 is located opposite the phalanges and forms a first protuberance on the upper face of the sole.
- the first protuberance is in front of the phalanges, that is to say in an area where the support of the foot during the force transmission phase is weak.
- second cavity or rear hollow 7 is located facing the arch of the foot.
- the possible second protuberance formed on the upper face of the sole and linked to the second cavity fills part of the hollow formed by the arch of the foot.
- the second cavity opens out only on the internal face of the sole.
- the protuberances linked to the integration of the wedges in the thickness of the sole are formed in suitable areas of the sole.
- the thickness of the top wall can be reduced by at least 30% in relation to the thickness of the sole around the hollow. It is even more advantageous to divide the thickness by at least a factor of two.
- the sole is rigid, that is to say, it is dimensionally stable when walking with a shoe comprising said sole.
- the sole is not perforated over its entire width, which prevents deformation of the sole and therefore reduces the transmission of forces.
- the foot is only separated from the upper face of the pedal by the sole and possibly a few comfort layers mounted on the upper face of the sole.
- the configuration presented makes it possible to form a metatarsal zone whose thickness is less than 4mm, that is to say much less than the conventional thickness of a nut which secures the wedge.
- the metatarsal zone 9 can optionally be covered with a reinforcing layer intended to protect the metatarsal zone 9 when the user walks with the sole.
- the reinforcing layer may optionally connect the front wedge to the rear wedge.
- the backing layer can also facilitate the sliding of the metatarsal area relative to the pedal. It is also possible to integrate the reinforcing layer directly into the sole, for example by overmolding.
- the thickness of the reinforcing layer is less than 1 mm.
- the underside of the sole 2 is particularly advantageous for the underside of the sole 2 to be curved or substantially planar.
- curve is meant that the underside of the sole rises from the metatarsal area to the front tip of the sole.

It is also advantageous that the lower surface of the wedge rear or inside the sole, that is to say that it protrudes from the lower surface of the sole outside the rear hollow or even is mounted flush.
- the front wedge is held in the sole by means of a fixing system, for example a screw. It is preferable that the front wedge comes to rest on the side faces of the first cavity, that is to say along the width of the sole without necessarily resting on the bottom wall.
- This configuration is mechanically more resistant than a wedge mounted on the sole.
- the rear wedge is held in the sole by means of a fixing system, for example a screw. It is preferable that the rear wedge comes to bear on the side faces of the first cavity.
- the front and rear wedges take advantage of the lateral faces of the cavities to increase the mechanical strength imparted by the sole and thus ensure better shear resistance during the separation operations between the sole and the pedal.
- the front hollow and / or rear hollow have a height greater than the thickness of the sole.
- the lower face of the sole in the front and / or rear hollow is located in a plane above the plane defined by the upper face of the sole around the associated protuberance.
- the metatarsal area has a thickness between the upper surface and the lower surface that is less than or equal to the depth of the rear hollow. The protuberance makes it possible to reinforce the sole.
- the comfort layer (s) which are arranged on the upper face of the sole to separate the foot and the sole.
- the sole is advantageous for the sole to be in one piece, that is to say formed by a single piece. It is also advantageous for the sole to include only the front cavity and the rear cavity.
- the integration of the front and rear wedges inside the thickness of the sole makes it possible to have a zone metatarsal without insert, wedge or other protruding elements.
- the metatarsal zone of the sole is preferably flat or flat in order to allow the formation of a larger contact zone with the pedal.
- the sole is made entirely of a composite material, for example of carbon fiber. It is also possible to provide a molded sole.

- the sole may include means for adjusting the rear wedge along the longitudinal axis of the sole so as to bring the rear wedge towards the front tip of the sole or towards the heel of the sole.
- the sole cooperates with a so-called automatic pedal pedal which has front and rear attachment devices 10, 11 which are intended to cooperate respectively with the front cleat 4 and the rear cleat 5.
- the pedal has a body with a rotation shaft which is intended to attach to the bike. The body revolves around the rotating shaft.
- the body defines a support surface which receives the metatarsal zone 9. During pedaling, the metatarsal zone 9 presses on the support surface which turns the crankset.
- the front attachment device and the rear attachment device are separated by the support surface and by the rotating shaft.
- the metatarsal zone of the sole comes to rest on the support surface and a front part of the sole comes to bear on a front part of the body. It is also advantageous for the rear part of the sole to rest against a rear part of the body.
- the body defines a cradle with the front and rear attachment devices 10, 11 mounted protruding.
- the body is preferably curved with a curvature identical or substantially identical to that of the front part of the sole. In this way, when the sole presses on the pedal, it has a larger bearing surface than the configurations of the prior art. which facilitates the transmission of a significant force on the rotation shaft and therefore on the crankset.
- the illustrated configuration makes it possible to form a rigid sole while being thin, of low mass.
- the application of a force of 25N applied to 170mm from the metatarsal zone facing the rotation shaft of the pedal results in a displacement less than or equal to 10mm, the metatarsal zone 9 being embedded .
- the effort and displacement are applied and measured at 170mm towards the heel to represent pedaling effort.
- the automatic pedal and the assembly formed by the sole and the front and rear cleats form a kit that facilitates the transmission of pedaling forces.
- the front hollow 6 and the rear hollow 7 respectively receive the front attachment device 10 and the rear attachment device 11 of the automatic pedal 3.
- the automatic pedal has a support area disposed between the front attachment device 10 and the rear attachment device 11 and facing a rotation shaft of the automatic pedal 3, the contact area 9 resting on the support area.
- the particular configuration of the sole with the front and rear cleats allows a more efficient fixation on the automatic pedal.
- the fixing kinematics remain conventional in order to facilitate their acceptance by the public. The process comprises the following steps:
