Definitions
- the present invention applies to shoe soles and relates to a device intended to help a user to adapt his walking or his race to the type of terrain traveled or the particularities of his leg / foot system.
- the type of terrain is characterized by its hardness, its forward inclination positive upward, negative downhill, inclined to one side or the other for a course on hillside field or road shoulder.
- the peculiarities of the leg / foot system refer to a form of arched legs for example, a position to correct, or muscles or joints to relieve or stimulate in a particular way.
- the invention also applies to a method of manufacturing the elements of the sole.
- Patents 900867, US 5199191, US 4129951 are examples thereof.
- Patent No. US 5406719 has a configuration in which 4 chambers can be isolated or placed in communication and where, thanks to the use of reservoirs, the pressure of the chambers whose pressure range is given during manufacture can be adjusted by the user a few tens of percent by maneuvering valves and the stroke of the pistons of the tanks.
- the sole is made of two sheets of elastomer welded following the layout of the zones.
- US Pat. No. 5,177,992 discloses a system in which pockets of the soleplate which, thanks to a valve, allow themselves to be filled at atmospheric pressure at each break in contact with the ground, are alternately and pseudo-randomly held in pressure. or free to deflate by a mechanical rotating winch system operated upon each contact of a push button with the ground.
- the purpose of this invention is to provide the wearer comfort and stimulate blood circulation by exercises.
- the device according to the invention overcomes these disadvantages, it consists in the establishment of a universal sole under the shoe that is of the city type, sport, hiking, rehabilitation or orthopedic and helping a user to adapt his walk or race to the type of terrain traveled or the particularities of his leg / foot system.
- each shoe comprises in general and for each shoe a sole consisting of flat serpentines tubes or elastic tubes, expandable and waterproof and each delimiting a zone or sealed pocket according to a marking front, rear, right and left sides of the foot, each coil, including the end is plugged, being filled with air, in independent quantity and pressure, by transfers from the outside to the coil, from the coil to the outside and from one coil to the other in multiple combinations controlled by a system of valves, connecting pipes, a collector, a venting and a pumping system with possibly overpressure protection, the whole being controlled manually.
- These areas may be for example 4 in number: the right front, and the left front at the sole of the foot, the right rear and the left back at the heel.
- the advantage of these transfers is to be able firstly adjust the overall height and hardness of the sole to ensure comfort, rebound or damping depending on the nature of the activity, to compensate for different leg lengths; and on the other hand to adjust the relative heights of each zone in the right and left direction to walk on the roadside, to relieve or stimulate the knee joints, for rehabilitation or correction of bone deformities, or in the forward direction and back to rest or work the front or back muscles up or down. It also makes it possible to improve the sports performances by reactions adapted to the different impulses.
- Hs will be performed at remote intervals for the case of corrections or several times per hour for an athlete working on different terrains or for different activities.
- the maintenance of characteristics for large intervals between adjustments is made possible by the tightness of the coils and the winnowing systems.
- the pumping system can take a simple form and consist of a receiving nozzle with a valve located in the thickness of the sole, this nozzle being connected to the collector and connectable to an external pump which will be placed the flexible temporarily in the nozzle for the pumping operation.
- This pump is therefore independent of the sole and takes the form for example of a manual piston pump or an electric compressor or other compressed air production unit.
- a mini pump model can be manufactured and delivered with the footwear with little financial impact, the pump can even be sophisticated with a pressure gauge if it is used by an orthopedist or professional managing multiple users.
- the pumping system may also consist of a mini pump for example piston, integrated into the sole and having the outer shape of a capsule. It will be equipped on the discharge side to the common manifold, a check valve and possibly a safety valve, and the suction side of a connection to the air filter generally placed in a protected area of the shoe via an isolation valve and a non-return valve.
- the external bearing surface of this pump is on the one hand much greater than the surface of its compression chamber, this in order to be able to deliver in the coils of any area of the air at a pressure greater than that due to the weight of the user compared to the total bearing surface of the boot on the ground, and secondly, so as to always be in contact with the ground, even when the sole around it is close to its maximum thickness , it is maintained at the bottom surface of the sole by virtue of its location and support under the lower generatrix of the pipes of the lower layer of the coils of the heel zones, which enables it to follow the increase in thickness of the the sole.
- the pumping action is done for example during a normal movement of the user, the pump being thus actuated by a portion of the weight of the user with each support of the foot on the ground.
- the pump keeps its retracted position with minimal thickness when its suction valve is closed.
- a configuration of the air transfer system consists of a simplest version of a set of valves with two open and closed positions controlled from control members located on the side in the thickness of the sole. Each valve is respectively assigned to an area, the venting, the suction of the pump.
- this manifold with the vent through the vent valve or isolating or opening the suction valve of the pumping system.
- valves 4 of which are assigned to zones.
- valve limits the pressure in each of the components to a safety value well below the static resistance limit pressure. This margin will allow to collect without problems pressure peaks due to shocks during contact with the ground. For settings with small differences in thickness between zones, you can simply print the desired shape by tilting the foot during a phase of communication of zones and close the valves in positron.
- Another configuration allowing the same type of adjustment consists of a transfer system comprising a plurality of four-position valves and several orifices controlled from control members located on the side in the thickness of the sole of the boot, these members being rotational maneuvering by the user according to the desired diagram, the first isolating valve or placing in communication the manifold, the vent, the suction and the discharge of the pump, the other valves isolating or placing in communication independently groups areas of the sole.
- Each valve consists of a rotating inner cylinder pierced by two coplanar radial bores forming a 90 ° angle and ending at their point of intersection on the axis of the inner cylinder, the valve block being pierced with four orifices placed at 90 ° in the same plane as the bores, the first valve having bores and block orifices placed in two different parallel planes.
- valves For a 4-zone configuration there are therefore 3 valves, the order of the holes in the valve block of the first manifold valve being manifold-vent-suction pump-discharge pump, manifold-manifold- front left- front right for the valve the front zones of the sole, and the rear left-rear right-hand rear-collection manifold for the valve of the rear areas of the sole.
- a probe can be mounted permanently, for example with a visual indication or piezoelectric type with pins accessible on the edge of the soleplate for electrical measurements.
- the streamers are of several characteristics.
- tubular elastic extensible and airtight rubber family generic term including natural rubbers, synthetic, elastomeric, thermoplastic, neoprene, butyl, polyurethane, silicone, fluoro elastomer ... or any other type of mixtures based on these materials whether opaque or transparent. They may possibly be armed by braiding elastic fibers and stretchable stiffer than the main material, such as for example non-limiting fibers made of nylon, polyester, lycra and other materials in combinations.
- the main axis of these reinforcements being the longitudinal axis as for example for a diamond-shaped mesh elongated in the direction of the axis of the pipe.
- the bursting pressure is at least 10 bars.
- the pipes can work in a non-pressure zone. They are indeed mounted empty, flat in the thickness of foam between the shoe and the outsole, and in the absence of
- This pressure keeps this flat shape maintained by the foam or the filling material outside the coil.
- the thickness of the sole is capped and becomes very stable with respect to the loads.
- One way to stabilize the thickness of the sole at low pressures is to use tuyaaK filled with a rubber or foam insert. In absence of air, or at low pressure, the sole acts as several superimposed layers of rubber and foam materials. The addition of pressure increases the thickness steadily with respect to the load. This
- a fluidity allowing it to be introduced between the empty spaces between; laces or through a wide mesh, whether the product is in liquid, pasty, gaseous, granular or locally pasty form.
- This fluidity may be due to temperature as for the injection, vulcanization, hot pressing and the like processes or the nature of the materials before polymerization transformation, setting, drying, stabilization or any other physical or chemical phenomenon making the materials stable and with the desired properties at the end of production.
- This not only allows for a compact and lightweight assembly, but also to control the lateral expansion of the entire sole. Indeed, for a configuration with a layer of pipes the natural tendency would lead to a lateral expansion equal to the expansion in height multiplied by the number of passages of the coil in 0 the lateral direction.
- the foam gap being energized during the vertical expansion of the coil, it will lengthen and narrowing effect will decrease thickness between two laces while exerting on each of them a lateral force due to the resistance to The compression will make them slightly oblong.
- Each zone may contain several superimposed layers of the same flat coil, the use of a multi-layer configuration makes it possible, among other things, also to limit the tendency towards lateral enlargement. It is thus possible to have, according to the diameter of the pipes two, trofe or more layers of coils. The choice of the diameter, the number of layers and possibly the possible diameter variations of the pipes for each zone of the coil thus allows many combinations.
- the standard diameters are essentially between 4 and 2 ⁇ 0 mm, the number of layers between one and five.
- the configurations with micro-tubes of 2 mm and up to 10 layers concern particularly impervious materials. It is also possible to limit lateral expansion by bandaging the parallel laces with a coarse mesh. A large-meshed canvas is furthermore tapered between each layer in order to increase the lateral stiffness and to prevent the sole from buckling under the effect of its various stresses.
- the purpose of the control of the lateral expansion is to reduce the stress and the eissf iteme ⁇ t stresses at the level of the connections of the various components of the soleplate, in particular at the level of the contact with the first assembly and at the contact with the soleplate. 'wear.
- an expansion is advantageous for increasing the support surface of the soleplate on the sides, and it may be advantageous to let it occur if the outsole is sufficiently extensible to avoid being hampered by this expansion or if its shape in a tray on the sides allows to take the shearing efforts and contain the swelling of the material. Whichever arrangement is chosen, care should be taken to always leave a relatively rigid element on the outer sides of the soleplate so as not to reduce the effective width of the soleplate, which would pose a risk to your ankles.
- foams with good compressive, but also shear and extension characteristics will be selected. Indeed, this foam participates in the recovery and the distribution of the weight of the user between essentially the zones of lower generators and top of the pipes and the outsole, first mounting or between intermediate plates. It also participates in the transmission of lateral forces and partially resumes by its tension the forces produced by the pipes when they tend to increase the thickness of the sole. This recovery makes it possible to maintain an acceptable stiffness during operation in low pressure zone with flattened pipes. In order to help the plates with their work of recovery of lateral forces and extension and to avoid the accumulation of stresses at their glued connection, it will be possible to use longitudinally striated plates with important glue thicknesses.
- this material will also meet good compression, shear and extension characteristics.
- the working temperature will always be below the maximum temperature of the materials used for the coils, their reinforcements, the valve block and the pump.
- the fluidity during the filling phase will be sufficient to pass between the pipes of even small diameter and the mesh of the canvases.
- the splicing of tubes or their connection to the winnowing system is done by insertion into a metal or hard plastic end piece with circumferential groove and banding with a flange made of nylon material. This arrangement allows quick assembly, economic and waterproof over time even at high inflation pressures. Special tips allow the joining of pipes of different diameters.
- the number of zones can vary between 1 and 8, with 4 being the most standard configuration.
- the number of valves, according to the selected winnowing principle, will then correspond to the cutting, the other characteristics remaining applicable for any configuratten,
- the shoe (1) has a lower surface (1.1) on which will be mounted the sole.
- the assembly of the coil (3) is sandwiched between the two plates of upper foam (2.1) and lower (2.2) whose faces are striated and have the imprint of the coil.
- the pump (4) and the valve block (5) are pre-mounted on the coil (3).
- the tray-shaped outsole (6) will receive the set judiciously inserted and glued.
- the top of the edges of the sole will be attached to the lower part of the shoe by the proper method of assembly (gluing, sewing ).
- a hole for the passage of the contact surface of the pump and holes for the passage of the valves operating buttons are provided on the sole.
- a very similar design would correspond to the case where the foam plates (2.1) and (2.2) would be injected or vulcanized depending on the melting temperatures of the different materials, likewise the use of a flat wear outsole fits following the same principle,
- Fig.2 Simplified sectional view at the heel representing shoe models I and II, differentiated by the number and diameter of the pipes of the coils, according to their different configurations: 0 A sole at maximum thickness, B sole at minimum thickness, C sole with maximate inclination,

- the shoes are shown in position with vertical force on column III and with lateral efforts on IV.
- the oblique lines on the IV column represent the maximum inclination obtained (short line) with respect to the best inclination obtained with the shoe Type I configuration C (long line at the outermost).
- the shoe sole type D gives you a worse result.
- Fig. 4 Simplified sectional view at the heel representing models of Type II shoes with medium diameter two-layer pipes with interposed grooved foam plates for gluing.
- the representation of the top shows a theoretical configuration with pipes in line, that of the bottom a theoretical configuration with offset pipes. Perfect alignment or offset in transverse planes of the coils is not possible due to the serpentine pattern of the coils, but can be searched for or not.
