Definitions

  • the present invention relates to a sole for shoes with a forced ventilation system.
  • Our invention forecasts two possibilities of air circulation : to suck outside the air and to inject it internally the sole or to suck the air internally the sole and to discharge it outside.
  • the pump In the systems actually known, the pump, the real engine of the system, as shown in Fig.1 and Fig. 2, generally is a bladder (1) produced soldering the edges (2-3) of two plastic shells, separately produced with the process of the injection moulding. From a hole of this bladder a tube (4) comes out:
  • the tube which can be formed by two half tubes (4a-4b) soldered together, has two arms: one (5) is directed toward the external edge of the sole, the other one (6) is directed toward the inner part of the sole.
  • the first one is joined to a pneumatic valve (7) which discharges air outside the sole, the second one is joined to a pneumatic valve (8) which sucks air internally the sole.
  • the bladder (1) generally has a low reactivity because its own construction, because its shape and because the used material, for these reasons it does not make the full suction within 200 milliseconds between two steps and therefore it works partially: this bladder (1) can not suck the humidity and the bad smells. Its soldering may be the cause of a breaking.
  • Our system forecasts a flow conveyor (30a) in the plant area which stores and conveys the air, humidity and smell through the pneumatic valves (19) joined to the tubes (17-18) connected to the pump (10) which discharges air, humidity and smell through the pneumatic valve (19).
  • This invention relates about a new technology for the air circulation inside the soles formed by four essential elements : -1- the pump connected through one or more tubes to -2- one or more pneumatic valves, joined to -3- a flow conveyor, the whole system can be excluded using -4- a special cap which close the external valve.
  • the pump can be produced without reactive elements inside (case A) or with them (case B).
  • Two aspects are to be considered : the mechanical one and the pneumatic one.
  • this plastic device is produced with the technology of the rotational molding, the only process which allows the pump's shape as here described, and using thermoplastic resins with a high elastic modulus.
  • This technology the soldering of two shells is avoided and this pump will be produced in only one body with the consequence that, during its continuous work, it will not have any possibility of break. It is formed by three parts.
  • the upper part (10) is dome-shaped, and located over the line (x-x) which corresponds to the inner surface of the sole being in direct contact with the heel. It is the real part in motion which generates the air flow.
  • the medial part of the pump (11), between the section x-x and y-y, is located in the medial part of the sole whose role is to be the tank of the air which will be moved, it has the same elasticity of the upper part.
  • the lower part (12) is located in the lower part of the sole and here all the connections with the tubes are made. This part has no elasticity being formed by a solid structure.
  • Fig. 4b the pump is compressed by the heel (20) and therefore the upper part (10) enters the medial part (11) bringing the axis x-x until the axis y-y forming a mechanical structure like a leaf spring and therefore very reactive with the consequence that, once the heel does not touch the upper part, the medial part reacts to return immediately to its natural position.
  • the air contained into the pump is moved inside and outside the sole because its pneumatic devices.
  • connections of these tubes are pre-formed (see Fig. 5).
  • valves can work for discharging air or for sucking it inverting their position.
  • This invention solves this problem relating how metal springs can be fixed in the proper way into a plastic system.
  • the spring (60a) has two or more coils, its best shape is the conical one.
  • the upper coil enters the fixing pin (54a) pre-formed on the inner surface of the plastic cover (50b).
  • the lower coil is fixed into the ring (55a) pre-formed on the inner surface of the lower plate (50a).
  • This fixing is the tightest as possible because is done in this way.
  • a transformer which transforms the common voltage in low voltage and connecting its positive and negative poles with two copper thin plates, if the lower coil is put in contact with these two thin plates, a short circuit is generated and for the Joule effect this coil becomes incandescent and immediately inserted into the ring (55a), amalgamating metal with plastic. Following this way a perfect fixing is guaranteed which will avoid any movement.
  • the use of the electricity with a transformer for this purpose allows a modular administration of the heating given the lower coil, avoiding the transfer of the heating to other coils otherwise they can lose their hardening.
  • plastic bellows (case b) is an up-to-date fact due to the production of new technopolymers with an high elastic modulus, like the thermoplastic polyester elastomers, which confer them a fast recovery like a metal spring. They are produced with the process of the rotational moulding or the blowing moulding.
  • These plastic bellows (60b), as shown in Fig. 8, are done with two or more convolutions.
  • the upper convolution has a hole (56) which has a bigger diameter than the diameter of the corresponding pin (54b) pre-formed on the inner surface of the plastic cover (50d).
  • the lower convolution has a reinforced base (58) with the same diameter of the corresponding pin (55b) pre-formed on the inner surface of the plastic plate (50c).
  • Said base (58) is soldered with said plate (50c) with the process of high-frequency or ultra-sounds. Both these processes can guarantee a perfect soldering around the whole perimeter of the base of the bellows.
  • the plastic box (50) so composed will have in the rear part, or external part, of the plastic cover one or more holes (51), where one or more plastic gaskets (53) will be inserted, into these gaskets one or more tubes (17) will be joined.
  • the last component is one or more pneumatic valves (19) which will be joined to the tubes (17). These valves have to be put with their head (23) externally.
  • the system will be composed by: one or more holes (52) where the consequent valves (19) enter through one or more gaskets (53) into which one or more tubes (17) are joined. These valves have to be put with the head (23) internally.
  • valves work each-other in an opposite way : when one is open the other one is closed and, as referred, inverting the sense of the valves also the sense of the air flow will be inverted : from discharging the air outside the sole to sucking the air inside it.
  • a tube 21). Internally this tube two essential components are placed: a piston (26) or a sphere (27), both these elements have the role to close the inner hole (25), and a spring (24) whose role is to keep in the proper position the closing element : the piston or the sphere.
  • the valve When these components are inserted , the valve is closed by the cap (23) which has internally a hole (22b) smaller than the hole (22a) of the tube (21). On the opposite side the valve has the hole (22a) into which the tube (17 or 18) enters. This tube may enter the tube (21) of the valve internally (17a-18a) or externally (17b-18b).
  • valves (19) or the tubes (17 or 18) will be placed, as shown in Fig. 3, into a special insert (30a), which will be called flow-conveyer, located in this area.
  • This device can be produced using different materials and different technologies.
  • this material is not breathable but it will be covered, on the side in contact with the foot, by a sharp layer (37) of leather or breathable non woven fabric. In this case the foot will be in contact with this breathable layer which will have down a plurality of reactive elements, the semispheres. The pressure given by the foot on the breathable layer moves the volume of air contained between the semispheres (Fi).
  • this "pluriball" with the upper layer may be done using a special glue, the only way to couple this material with leather, or with a thermic treatment in case of the non woven fabric.
  • Another way for obtaining a very good result for the suction of the air is to couple two layers of this material, pluriball, putting the semispherers in contact between them, to solder the external edges of the two layers together and to make some holes on the surface in contact with the foot.
  • the conveyor is like a wide blister with a plurality of reactive element inside, the semispheres, which reacting under the foot pressure generate the needed movement of air sucked by the holes of the external surface.
  • the flow conveyor will have a plastic tank (35) as shown in Fig. 14. It is essentially a bladder, pre-formed with a plurality of holes (36) on the front part, and a hole (38) for the joint to the valve (19) in the rear part. It is fixed to the flow conveyor soldering its edges (39) to the sheet (31). Its role is to give more sucking force to the air circulation around the entire flow conveyer and to direct it toward the tubes (17 or 18) and to the pump which, with its natural force, will discharge the air outside (Fd) through the valve (19) as shown in Fig. 15.
  • This flow conveyor when compressed generates a movement of air which will be sucked directly by the tube (17 or 18) or by one or more arms (34) derived by the same tube, as shown in Fig. 16.
  • This tube, and eventually these arms, for a better result will be produced with a plurality of holes (34a), in order to suck more quantity of air in more points of the conveyor.
  • This cap is produced with the process of the injection moulding, using thermoplastic resins and, as shown in Figs. 6a and 6b, this cap is formed by the following parts.
  • Fig. 17 the dynamics of the whole system is shown, referring, as said, to the discharging of the air outside the sole.
  • the plant of the foot is leaving the ground and, making this movement, compresses the retractile elements (32-33) of the flow conveyor and the air contained between them moves through the tank (35) and the tubes (17-18) inflating the pump.
  • the valve located in the front side (F) is opened (O)
  • the valve located in the rear side ( R ) is closed (C) and the flow conveyor is obviously totally empty of air.
