Definitions
- the present invention relates to the measurement of the forces exerted on a studded shoe.
- Application US 2007/0261271 A1 describes a shoe sole with studs provided with deformable studs.
- the sole has an electronic circuit which includes a sensor such as an accelerometer, and which is arranged to control actuators present within the crampons, making it possible to modify their shape.
- Application ER 2864883 A1 describes a device for attaching a crampon to a sports shoe.
- the invention meets this need with a crampon comprising:
- a stud body at least partially defining the external surface
- a connecting part connecting the body to the base so as to allow the body to move relative to the base under the effect of a force exerted on the body of the crampon by the wearer of the shoe
- At least one sensor sensitive to a displacement of said body and / or to a deformation of the connecting part during this displacement.
- the invention makes it possible to measure at least one mechanical stress exerted on the crampon during the evolution of the sportsman who wears the shoe, without modifying the feeling or the comfort thereof.
- Knowledge of this constraint can be used to optimize the shape of the studs. It can also be used to monitor the athlete’s physical condition.
- the presence of the base ensures the fixing of the clamp without the need to provide a seal as in the aforementioned prior art.
- the invention makes it possible to measure the forces transmitted between an athlete's shoes and the ground at the grip points that constitute the studs, in three directions if desired, namely a direction coincident with the axis of each crampon and two directions perpendicular to this axis. This makes it possible to go back to the resulting force transmitted by the attachment point as well as its direction.
- This solution is not invasive and the invention makes it possible, while respecting a standard screw pitch (for example that of the World rugby Regulation 12 BS 6366 standard: 20l l + Al: 20l7 September 2011 Specification for studs for rugby football boots or that of a brand of shoes) for fixing the crampon to the sole to be suitable for any shoe with cleats.
- the invention can implement a data acquisition system which can be internal or external to the shoe, or even miniaturized and directly integrated into the crampon.
- the invention makes it possible, if desired, to use exactly the same dimensions, external shape and grip characteristics as those of the studs commonly used, not modifying the feeling or the comfort of the user.
- the structure of a crampon according to the invention namely with two physically distinct parts, one part of which internal dedicated to the measurement and an external part in contact with the ground, allows the user to modify the grip characteristics on the ground by changing the external part to adapt to the conditions of the ground without modifying the measure part.
- the body of the stud is detachably fixed on the connecting part, in particular by being screwed thereon.
- This can make it possible to easily mount various forms of crampon body, and to study the impact of this on the forces encountered during the movement of the wearer of the shoe.
- This can also make it possible, as mentioned above, to choose the shape of the crampon that best suits a type of terrain or game, for example.
- the spike body is fixed to the connection part using an attached fixing element such as a screw, the latter being for example screwed into a tapped hole in the connection part.
- the senor is placed on the connecting part and reacts to a deformation of the latter.
- the crampon may include three sensors arranged so as to measure the stresses exerted along the x, y and z axes of an orthonormal reference associated with the crampon, the z axis being coincident with the longitudinal axis W of the crampon.
- the connecting part being elongated along the z axis, the sensors intended to measure the stresses along the x and y axes are preferably constituted by strain gauges arranged on the connecting part so as to be deformed by bending of the connecting part, said gauges being preferably closer to the end of the connecting part connected to the base than to the end of the connecting part connected to the body of the stud. This makes it possible to benefit, for a given effort, from a greater amplitude of deformation of the connecting part, and therefore from a better sensitivity of the gauges.
- the sensor intended to measure the stress along the z axis can be placed on the connection part by being closer to the end of the latter connected to said body than to the end connected to the base.
- the base has a threaded hollow axis screwed onto the sole.
- the hollow axis allows the passage of a connection between the sensor or sensors present in the crampon and an acquisition circuit which is for example integrated into the sole, for example in its heel.
- the hollow axis can thus be traversed by at least one electric cable connected to said sensor.
- the connecting part comprises a cylindrical part on which the sensor or sensors are mounted.
- This cylindrical part can be of circular cross section or not, for example polygonal, preferably square.
- the connecting part may include a portion forming a beam, made of steel. This portion forming a beam can be constituted by the aforementioned cylindrical part.
- the connecting part is of flattened cross section, in particular is in the form of a blade.
- a flattened section gives increased deformability in a direction perpendicular to the flattening plane.
- a blade-shaped connecting part can thus easily allow, depending on its orientation, to measure a stress exerted along the longitudinal axis of the sole or perpendicular thereto.
- the connecting part can be given still other shapes, in particular one whose cross-sectional profile gives preferential deformability in one direction.
- the connecting part can thus be hollowed out, and for example formed by two parallel uprights joined at their ends. These amounts can have the shape of two parallel blades for example.
- the connecting part can have various shapes, for example parallelepiped. In longitudinal section, the recess may have a rectangular shape, a shape of eight or oblong.
- the connecting part can be arranged to deform, when a stress is exerted laterally on it, forming an inflection.
- the connecting part can be equipped with at least two sensors arranged on either side thereof above the inflection and at least two other sensors arranged on either side of the part bond below the inflection.
- the measurements made by the sensors make it possible to directly calculate the force responsible for the deformation, without going through the calculation of the moment of the force.
- a connecting part comprising two spaced parallel blades joined at their ends deforms forming an inflection and is therefore particularly suitable for such a measurement. When a force is applied, the distal part tends to shift laterally from the proximal part, the blades bend.
- the base may be wider at its contact surface with the sole than the body at its upper edge.
- the base has an outer surface which is substantially in line with the outer surface of the body.
- the edge formed at the junction between the lateral surface of the base and the underside thereof facing the body may be of diameter greater than that of the upper edge of the body.
- the clamp comprises an acquisition circuit connected to the sensor (s) and preferably a memory for recording data coming from the or sensors and / or a system for wireless transmission of this data to a remote computer system. This allows all the electronics to be concentrated in the crampon, which can then be attached to a normal shoe, devoid of electronics.
- the stud may include at least one electrical cable for connection to the acquisition circuit.
- This cable can go up towards the sole through in particular the aforementioned threaded axis, as mentioned above.
- at least one electrical cable can pass through the base without penetrating the hollow threaded axis, for example by virtue of a passage made through the base which is parallel to the threaded axis or which forms a bend at the interior of the base, for example at a right angle, with parts respectively parallel to and perpendicular to the threaded axis. If necessary, the cable leaves the stud without passing through the sole.
- the invention also relates to a studded shoe, comprising at least one stud according to the invention, as defined above.
- the shoe may include, as mentioned above, an acquisition circuit connected to said sensor, in particular by a cable.
- the acquisition circuit can be arranged in the sole.
- the acquisition circuit may include a memory for recording data from said sensor and / or a system for wireless transmission of this data to a remote computer system.
- the shoe can be a shoe for a football or rugby player, among others, the invention applying to any studded shoe in general.
- the shoe may have only one stud according to the invention, or alternatively several studs, preferably at the front and at the rear. Preferably, all of the studs of the shoe are connected studs according to the invention.
- the shoe advantageously comprises a first crampon according to the invention, the connecting part of which is arranged to deform in a privileged manner in a first direction and a second crampon according to the invention, whose connecting part is arranged to deform so privileged in a second direction, different from the first.
- the connecting parts of the first and second spikes are in the form of a blade whose flattening planes are perpendicular to each other.
- the first direction can be substantially aligned with the longitudinal axis of the shoe and the second with the transverse axis.
- the first spike is for example located under the big toe and the second spike is for example located on the lateral outer side, substantially at the level of the metatarsal heads.
- the shoe may have only two studs instrumented according to the invention.
- the subject of the invention is also an assembly comprising a shoe as defined above and at least one additional spike body, which can be substituted for that present on the connecting part and having for example a surface condition and / or a different shape and / or different material.
- the user can thus have at his disposal a range of spike bodies and choose the one best suited to the state or nature of the terrain for example, in particular natural, synthetic or hybrid terrain, dry or wet, or to climatic conditions. .
- the subject of the invention is also a method of acquiring data representative of at least one mechanical stress exerted on the studs of a studded shoe when the shoe is worn by a person, in which data representative of said stress are acquired using a crampon as defined above.
- the data is compared to benchmark data and information related to a player's performance status is generated.
- the subject of the invention is also a method of configuring a studded shoe, in which a data acquisition is carried out using the aforementioned method, this data is analyzed and a form of stud is selected. among several depending on the data thus analyzed.
- a stud comprising a fixing part to be fixed to the sole, a body defining at least partially the external surface of the stud, in contact with the ground, and a connecting part connecting the body to the fixing part, at least two sensors for measuring the stresses in x and y directions of a frame associated with the stud, the z axis being coincident with the longitudinal axis of the crampon, and a sensor for measuring the compression stresses along the z axis, this sensor being closer to the distal end of the crampon, that is to say the one farthest from the sole, than the two other sensors.

- the stud 3 has a base 10, for example metallic, having at the upper part a hollow axis 11 threaded with axis W, arranged to be screwed into a corresponding housing provided on the sole 2.
- the outside diameter of the axis 11 and the thread pitch are chosen so as to be able to equip with a crampon according to the invention a standard sole of an existing shoe.
- the base 10 can widen towards the sole 2, as illustrated, and have an upper face 12 which is planar and perpendicular to the axis Z, to which the axis 11 is connected, and a lateral surface 13 of rounded shape, preferably symmetrical in revolution, for example in the general shape of a torus portion.
- the base 10 may have a stepped lower face 14, with a central part 15 to which a connecting part 20 is connected.
- the latter has an elongated shape along the axis Z, with a cylindrical part 21 of axis W provided in the lower part with a flange 22, the latter being extended downwards by a solid threaded axis 23, of smaller outside diameter than the cylindrical part 21.
- the cylindrical part 21 may be axially symmetrical, and preferably of square section. The diameter of the cylindrical part is in this case that of the circle which passes through the edges.
- the connecting part 20 and the base 10 can be made monolithically from steel, in particular from stainless steel.
- the stud 3 has a body 30 which is fixed to the connecting part 20.
- the body 30 has a lower part 31, for example planar and perpendicular to the axis W, which is extended at its periphery by a conical side wall 32 widening upwards.
- the upper end 33 of the body 30 is located at a non-zero distance d from the lower face 14, and also surrounds the central part 15 at a non-zero distance j.
- the axial clearance d existing between the lower face 14 and the upper end 33 is for example between 0.1 and 1.2 mm.
- the small space existing between the upper edge 33 and the lower face 14 limits the penetration of earth or other elements found on the ground in the space inside the body 30, despite the absence of a seal. Where appropriate, a seal is provided to close this space between the body 30 and the underside 14.
- the base 10 may be wider at its contact surface with the sole than the body 30 at its upper edge 33.
- the lateral surface 13 is substantially in line with the exterior surface of the body.
- the edge formed at the junction between the lateral surface 13 of the base and the lower face 14 thereof facing the body may be of diameter greater than that of the upper edge 33 of the body 30.
- the lower part 31 is crossed by a threaded hole 36 of axis W, into which the threaded axis 23 is screwed, and the lower end 23a of the latter comes for example flush with the lower face 35 of the body 30 or slightly set back from it.
- the body 30 is for example made of stainless steel.
- FIG. 1 shows an additional body 30 ′, the surface finish of which is different, for example rough while that of the body 30 in place is smooth.
- the range of different bodies that can be fitted to a crampon may generally include at least two bodies which differ by at least one from:
- the connecting part 20 constitutes an internal part of the stud which is the instrumented part and the body 30 constitutes an external part whose only link with the internal part is at the level of the threaded axis 23, which is the only link between these two rooms.
- the connecting part 20 constitutes a beam which deforms slightly under stress. Depending on the direction and the norm of the force, the deformations of the beam are not identical. The measurement of these deformations makes it possible to go back to the force C exerted on the stud.
- the connecting part 20 is dimensioned so that the maximum deflection for a stress equivalent to a weight of 100 kg, exerted on the crampon along x or y, results in an deflection between 100 and 500 microns, preferably of around 300 microns.
- the connecting part 20 is made of steel in order to resist the stress, with a section small enough to have measurable deformations.
- the spike 3 is equipped with sensors providing information on the movement of the body 30 relative to the base 10 under the effect of the stresses exerted on the spike 3 during the movement of the carrier.
- sensors are mounted on the connecting part 20 to measure its deformations, which are representative of the movements of the body 30 relative to the base.
- connection part there are thus three sensors on the connection part so as to measure the stresses exerted along the x, y and z axes.
- the sensors 40 intended to measure the stresses along the x and y axes are constituted by strain gauges arranged on the connection part 20 so as to be deformed by bending of the connection part, in a location closer to the upper end of the connecting part connected to the base than of the lower end of the connecting part connected to the body of the stud. This gives an amplitude of bending deformation of the connecting part 20 greater than what it is at the lower end thereof.
- the sensor 41 intended to measure the stress along the axis z is disposed on the connecting part 20 being closer to the lower end thereof than to its upper end.
- the sensors 40 and 41 can be bonded to the surface of the cylindrical part 21, on respective faces of the latter.
- the sensors 40 and 41 are preferably surrounded by a sheath or encapsulation of a material which seals against water, with respect to possible penetrations of liquid by the play existing between the upper edge 33 and the base 10.
- the choice of the section and the length of the connecting part 20 is made according to the characteristics and details of the gauges used.
- the length / of the connecting part 20 measured along the cylindrical part 21 between the shoulder at the base of the flange 22 and that at the base of the central part 15 is between 6 and 14 mm and the cross section of the cylindrical part is for example between 10 and 30 mm 2 for a connecting part made of steel.
- the cylindrical part 21 can be of square section, which can facilitate the mounting of the sensors, on the flat faces of the latter.
- three gauge half-bridges are used, one for the measurement along the x axis, one for the measurement along the y axis and a last for the measurement along the z axis.
- the tangential forces along the x axis are obtained by means of a half bridge of gauges mounted as an inverter, where the gauges replace the resistors Ri and R 2 in the Wheatstone bridge illustrated in FIG. 5.
- the two gauges used being offset by 90 ° relative to the gauges used for the measurement of the stresses exerted on the crampon along the x axis.
- the normal force that is to say along the z axis, is measured via a straight half-gauge bridge, where four gauges replace the resistors Ri and FL in the Wheatstone bridge 114 of FIG. 5, so that measure compression.
- the four gauges are placed on the lower part of the cylindrical part 21, where the flexion is the weakest, to have sufficient precision on the compression measurement.
- Two gauges are connected together electrically in series without inverting them to replace the resistor Ri and the same is done with the other two to replace the resistor FL. In a variant not illustrated, only two gauges are used.
- the bridge is powered by a generator G, as illustrated.
- the signals from the bridge can, for each measurement channel, be amplified at 110, then converted into digital form at 111, and processed by a microcontroller at 112, for example of the ESP8286 type or the like, having a wireless connection, for example Wif ⁇ , making it possible to transmit useful information from a distance.
- the wires then extend to the processing circuit 150 present in a housing in the sole, for example located at the heel.
- the sole 2 is for example made from a Wiz Wedge brand sole, already having a housing in the heel to accommodate the circuit 150.
- the data collected by the circuit 150 can be sent by Wif ⁇ or by any other means of wireless communication adapted to a remote receiver 200 such as a computer or other capable of carrying out the analysis, for example mobile phone or tablet, as illustrated.
- a remote receiver 200 such as a computer or other capable of carrying out the analysis, for example mobile phone or tablet, as illustrated.
- a memory card is placed in the shoe to record the information.
- Yet another solution consists in embedding all of the data acquisition technology directly in each stud. In this case, a processing circuit arranged in the sole is no longer necessary.
- the studs 3 communicate wirelessly with the processing circuit 150.
- the information sent from the boot can be analyzed, either in real time or a posteriori, by software allowing calculation of the forces exerted on each stud 3 as a function of the measured constraints.
- This software can display the results of this analysis, for example in the form of a map of the forces between the shoe and the ground at a given time.
- FIGS. 6a, 6b and 6c illustrate possible shapes in section of the connecting part 20.
- the connecting part 20 can have a square section as illustrated in FIG. 6a or a circular section as illustrated in FIG. 6b.
- the connecting part 20 may have a generally flattened shape of rectangular section.
- Such an arrangement gives the connecting part a blade shape and makes it possible to measure the stresses, in a preferred direction x or y in particular, depending on the orientation of the blade.
- Such a shape of the connecting part minimizes the disturbances of the measurement linked to the torsion of the connecting part.
- a single sensor may be sufficient to measure the stress exerted along one of the x or y axes. In this case, only one measuring bridge can be used. This can reduce the number of wires required to transmit the data to the processing circuit compared to the embodiment where a measurement is made along the three axes x, y, z. In the example considered, we can thus have four wires, namely two for the power supply of the bridge and two for the feedback of information to the amplifier.
- the wire or wires can pass through the base 10 and exit on top of the latter, as shown in FIG. 7, without passing through the threaded axis 23.
- These wires pass for example through a hole 18 'which is parallel to the hollow axis 11.
- they can exit on the side of the base 10 through a hole 18 ”which is bent, as shown in Figure 8.
- FIG. 9 shows a crampon 3 produced according to one of these two variants, the cable 149 connecting the crampon to the treatment circuit 150 being able to remain outside the sole.
- This embodiment makes it possible to have a crampon 3 independent of the shoe 1 and usable on a standard sole. Cable 149 can be glued to the sole, if necessary.
- the shoe 1 can have only two studs 3a, 3b instrumented.
- Each may have a blade-shaped connecting part 20 and be provided with a single sensor making it possible, by the orientation of the blade, to measure the stresses along the x axis or the y axis.
- the stud 3a is arranged for example under the big toe and the other 3b can be arranged under the metatarsal heads close to the outer lateral edge of the shoe, close to an outer lateral edge.
- the clamp 3 a is arranged so that the blade deforms in bending along the axis x in order to measure the stresses exerted along this axis.
- the clamp 3b is arranged so that the blade deforms in bending along the axis y in order to measure the stresses exerted along this axis. Such an arrangement makes it possible to assess the stresses exerted on the shoe during an overflow framing and / or during propulsion.
- the recessed connecting portion 20 forming two parallel blades.
- Four sensors 40a, 40b can be placed on the connecting part 20 on either side of the two blades.
- the connecting part 20 is formed of a single blade, the measurement of the sensor only makes it possible to measure the moment of the force exerted on the crampon. It is then necessary to know the point of application to deduce from this moment, the force. Illustrated in FIG. 12, the deformation undergone by the bimetallic strip when a force F is applied.
- Figures l3a, l3b, l3c illustrate variants of the obviously geometries 24 of the connecting part 20.
- the choice of a particular geometry may depend on the manufacturing methods and the desired strength.
- FIG. 14 illustrates a variant of the fixing of the body 30 on the connecting part.
- the connecting part 20 is tapped.
- a screw 25 is screwed into the threaded part of the connecting part 20 and thus fixes the body 30 thereon.
- the stresses exerted on the crampon can still be measured in another way, by having sensors sensitive to the distance separating the upper edge of the body 30 and the base 10.
