Definitions

  • the present invention relates to the field of shoes and in particular adaptations to optimize the phases of cushioning, support and propulsion stride.
  • a stride is likely to break down into three phases: reception, support and thrust.
  • the state of the art offers a plurality of shoes capable of achieving cushioning of the reception phase in the best conditions. These shoes use the same principle namely the compression of an elastic means during the reception phase.
  • shoe designers have been led to propose shoes that can improve the thrust phase by also using a resilient means to restore a portion of the energy stored during the push phase.
  • the shoe When cushioning is preferred, the shoe provides shock absorption at the reception and does not provide support for propulsion.
  • shoes adopting such improved features have their configuration dedicated and can not return to a configuration with conventional features allowing a stride and a conventional walk.
  • WO 2005/011419 describes a shoe sole for walking, running and jumping, ensuring the recovery of energy during the support phase and redistributing it during the pushing phases.
  • this sole which, in one embodiment has the form of a parallelogram, merely manage the approximation and removal of the horizontal parts of the parallelogram by means of a spring working in tension. The articulation between the sole part linked to the forefoot and that linked to the back of the foot does not exist or is not controlled by said parallelogram.
  • Another object of the invention is to provide a shoe respecting the natural stride.
  • Another object of the invention is to provide a shoe likely to return to a conventional configuration to practice including walking in normal and comfortable conditions.
  • the second front part secured to the foot part of the forefoot is extends rearwardly of said first hinge axis in a lever arm portion and projects rearward in the same plane as that of the front portion and kinematically secured thereto.
  • the first hinge axis is therefore located in a median position between the front end of the second front portion and the rear end of said lever arm.
  • the extension of the front sole respects a proportion of length 2/3 (two-thirds) and 1/3 (one-third) on either side of the axis of articulation, ie 2 / 3 for the front part and 1/3 for the back part.
  • the rear end of this arm has a second axis of articulation with the end of at least one elastic module whose other end is articulated around a third axis of articulation secured to the rear end of the part. back of the sole so that when the triangle formed by the three hinge axes flattens, the three axes become substantially coplanar and the elastic module is compressed and jammed.
  • This damper has a variable length, variation accompanied by an elastic module which will allow the triangular triangle or prism formed by the three hinge pins to flatten to compress the damper and to remove it during the release of the last.
  • This flattening creates a blockage of the system at the end of the race. Indeed, the elastic modulus working compression is blocked by the alignment effect of the three points of articulation, that is to say when the hinge axes become substantially coplanar.
  • This elastic module makes it possible to restore the accumulated energy at the right moment, namely for the propulsion phase.
  • Another aspect studied by the Applicant relates to the duration during which the stored energy is restored. All energy is restored during the heel detachment phase by a rotational movement about the first axis of articulation (front hinge pin), the spring bearing on the ground and pushing on the back of the heel. The restitution is optimal.
  • the release of said elastic module is carried out gradually to accompany the foot during most of the propulsion phase. This slower restitution than existing devices and processes, allows to better respect the ligamentous tissue and to assist the contraction and muscle relaxation of the propulsion phase.
  • the method implemented by the sole of the invention proposes a restitution of the elastic modulus over a longer duration than the duration of the storage phase.
  • said shoe comprises two elastic modules arranged on either side of the foot in the concave volumes of the sole corresponding to the natural outer and inner cavities of the arch.
  • Such an arrangement allows the three axes of articulation, as well as the damper and the two parts of the soleplate to align (to become coplanar) causing the neutralization of the damper.
  • Such an external and visible disposition makes it possible to give the shoe an attractive aesthetic appearance by providing it with a high-tech design.
  • the stability and the weight of the shoe are further improved because the moving parts can be brought together without the elastic modules being interposed between. Indeed, these dampers are integral with the outer edges of the moving parts allowing them to come into contact.
  • the ease of access to dampers facilitates their adjustment and interchangeability. This easy setting will allow the management of the pronation by playing on different settings between the inner shock and the outer shock.
  • an embodiment of the shoe of the invention comprises a single elastic module or external damper.
  • the joints being constituted by pivotal links, the presence of a single damper allows the same movements.
  • the elastic module is arranged and articulated with respect to the two parts of sole assembly so that the direction of the tension forces of said elastic module is positioned substantially parallel to the ground when the two parts of the sole join.
  • the maintenance under tension then operates according to a latch system where the elastic module is found in a position of mechanical dead center without the need for a stop when the shoe is at the end of the damping phase.
  • said elastic module operates in compression. This feature has the advantage of compressing the shortest elements and pulling the longer elements which avoids oversizing the different parts forming the sole.
  • the sole of the invention substantially resumes the width of a conventional sole and also allows the reception of dampers in the two hollow formed by the arch on both sides of the foot and thus by the shoe.
  • the shoe offers for the same elastic module formed by the two dampers a different direction and stroke for powering up and for release.
  • This different race will make it possible to implement the method of proposing a phase of restitution more progressive and slower than the storage phase corresponding to the respective different needs of the runner for the phases of reception and propulsion.
  • the elastic module comprises at least one spring.
  • said module is constituted by one or more springs associated with rods whose ends are hinged respectively to the movable front part of the sole and the rear part.
  • the stiffness of the elastic modulus is defined so that the action of the weight of the user on the shoe makes it possible to reach the support position where the elastic modulus is inactive with respect to the shoe and wherein the lower surface of the rear portion of the soleplate engages the upper surface of the rear arm of the front portion of the soleplate.
  • each damper is independently adjustable for example over a range of one to ten kilograms.
  • a set of several dampers makes different shock absorbers available for each ten kilograms.
  • the shoe of the invention proposes a return to an unaccompanied and undamped gait or stride.
  • said shoe comprises a locking means of the two parts of the sole between them in support phase where they are coplanar to prevent for example the effects of the elastic module during the other phases.
  • Said locking means keeps the two parts of soles in contact in the position taken in the support phase.
  • This locking means completely cancels the effect of the elastic modulus and brings the shoe back to a conventional configuration making it possible to practice walking in normal conditions.
  • This locking means also makes it possible to maintain, if it is not released, a configuration classic to the shoe. Being accessible from the outside, this locking system allows the user implementation by remaining shod with the help of the ground, the hand, the other foot, etc. ....
  • the working method consists in locking the boot in the support phase to adopt a conventional shoe operating method.
  • the boot comprises a means for locking the elastic module in the compressed position.
  • the movement of the two parts of sole assembly is accompanied by a ratchet type system that is released only once a certain angular amplitude reached between the forefoot and the back of the foot.
  • the boot comprises a disengaging device which is placed on the user's command from a disengaged position where the elastic module (s) are inactive and free at an engaged position where the elastic module (s) accompany the movement of the sole parts.
  • the locking means mentioned above will prevent the movement of the sole portions between them when the elastic modules are disengaged.
  • the connection between the damper rod and the third hinge pin is controlled by a control button which passes from a engaged position to a disengaged position and vice versa.
  • the engaged position holds the rod end in position relative to the hinge axis so as to allow the sole to transmit its movement to the damper for compression purposes and the damper to transmit its energy to the sole during its extension.
  • the disengaged position allows the rod of the damper to slide perpendicularly relative to said third axis of articulation so that the movement of the movable parts of the sole only makes slide the damper rod perpendicular to the axis of articulation without these compress or stretch.
  • This solution has the advantage of not involving the dampers without blocking the joint between the two main parts of the sole.
  • the lower and upper surfaces of the soles then come into contact at the connection module when the elastic module is compressed or inactive.
  • soles 100 and 200 are articulated along a first horizontal transverse axis A1 referenced substantially under the natural articulation between the forefoot and the back of the foot.
  • the second front portion 200 integral with the foot portion of the forefoot is extended towards the rear of the hinge pin A1 in a lever arm portion 210 and projecting towards the rear in the same plane as that of the front part.
  • the hinge axis A1 is therefore located in a median position between the front end of the second front portion 200 and the rear end of said lever arm 210. As illustrated, this median position is about 2/3 and 1 / 3, ie 2/3 for the front part linked to the footwear part and 1/3 for the rear part linked to the fender.
  • part 210 corresponds to one third of the total length of part 200.
  • This arm 210 has a second axis of articulation A2 with the end 310 of at least one damper 300 whose other end 320 is articulated around a third axis of articulation A3 integral with the part back 100 of the sole.
  • This damper 300 has a variable length, variation accompanied by an elastic member 400 which will allow the triangle formed by the three hinge axes A1, A2 and A3 to flatten to compress the damper and to remove it at the release of the latter.
  • this triangle is flattened, the three axes of joints become substantially coplanar allowing jamming of the shock absorber phase support.
  • shoe C comes into contact with the ground via the sole portion 210 at the second axis of articulation A2.
  • the damper 300 thus damps the impact and compresses throughout the next phase.
  • the rear portion 100 is raised relative to the front portion 200 remained on the ground around the first axis of rotation A1 which allows the damper to unjoin and relax thereby contributing to the thrust force by pushing against the ground in A2 and the heel at A3 during the propulsion phase.
  • this sole embodiment accommodates two dampers 300 disposed on either side of the rear portion of the sole 100 and positioned to occupy the concave volumes left free under and on either side of the conventional soles.
  • the sole of the invention has a standard sole width.
  • damping devices are equipped with elastic modules constituted by compression coil springs.
  • the original use of the compression rather than the traction avoids oversizing of the part constituting the sole avoiding an oversize damaging the proper use of the shoe.
  • This triangular configuration of the sole can evolve into a parallelogram configuration as illustrated by the drawings of the Figures 5 to 8 .
  • This configuration is more suitable for a stride or a step where the heel will come first in contact with the ground S as illustrated in the drawing of the figure 5 to dampen said contact by providing a movable midsole 500 articulated with respect to the front portion 200 of the sole on the one hand, at a first end 510 about said second axis of articulation A2 and on the other hand, around a fourth axis of articulation A4 carried by the lower end of a link module 600 whose upper end is articulated around the third axis of articulation A3.
  • the hinge pin A4 is disposed on said movable midsole 500 so that the connecting module 600 is parallel to the front portion 200 of the sole so as to form a parallelogram configuration.
  • the length of the soleplate 500 is equal to the length of the soleplate 100
  • the arms 600 have a length equal to the arm 210.
  • the support phase sees the abutment of the lower face of the rear portion 100 of the sole with the upper surface of the rear arm 210 and the intermediate sole 500.
  • the various axes of articulation are then substantially coplanar.
  • the operating principle is equivalent to that of the triangle configuration with respect to compression, holding in a compressed position and expansion. Simply, it is no longer the front part 200 of the sole that comes into contact first and triggers the folding of the triangle but the rear part of the movable midsole 500 which causes the beginning of folding of the parallelogram.
  • FIGS. 9 to 12 illustrate a particularly advantageous feature of the invention proposing to engage and disengage the elastic modules and therefore the dampers without blocking the joints.
  • the upper end of the damper rod 300 ' is equipped with a head cooperating with a control button 700.
  • This control knob 700 passes by rotation of the disengaged position illustrated by the drawings of the figures 9 and 10 where the damper 300 'is deployed regardless of the phase in which the sole is located, the position of the axis A3 does not affect the compression of the spring 400, the engaged position illustrated by the drawing of the figure 11 where the head 310 'is articulated in a pivotal connection only to the axis A3 so that the relative translation movements of the axis A3 with respect to the axis A2 are carried on or accompanied by the damper 300'.
  • control knob 700 is equipped with a cylindrical projection forming crank pin 710 eccentric with respect to its axis of rotation.
  • This crank pin 710 cooperates for sliding or holding in position with a path 311 'formed in the head 310' of the damper 300.
  • This path 311 ' has a portion 312' parallel to the axis of the spring 400 and a portion 313 'perpendicular to the latter.
  • the rotation of the knob 700 makes it possible to move the crankpin 710 to a disengaged position where the axis of rotation A3 and the axis of the crankpin 710 are in the portion 312 'parallel to an engaged position where the axis of rotation A3 and the axis of the crankpin 710 are in the perpendicular portion 313 'of the path 311' formed in the head 310 '.
  • the rear arm 600 ' is constituted by a triangle which is made of a deformable semi-rigid material allowing the two platforms 100 and 500 formed by the parallelogram not to remain parallel to the first contact with the ground to return parallel at the end of race when the two platforms 100 and 500 come into abutment which facilitates the natural pronation.
  • said arm is constituted by two independent arms.
  • the figure 14 illustrates an embodiment of the sole forming part of the invention in that the shoe comprises a lever arm 210 'also articulated to the front portion 200 coaxially with the axis of articulation of the rear part with the part A1 front sole bringing an additional hinge. Such articulation facilitates the implementation of the locking of the elastic module in the compressed position.
  • the elastic module is of the gas spring type.
  • the material used for the sole elements and the arm are semi-rigid plastic type or composites. They are made of hard materials of the steel or ceramic type for the axes and other connecting pieces.
