Definitions

  • the present invention relates to a shoe with internal sole.
  • a heat pipe is an element of heat transfer comprising, in a thin volume delimited by a sealed enclosure, a fluid to change liquid / vapor phase, such as water under tension
  • the heat pipe which is an element of thermal conditioning of the article of clothing or footwear, can be integrated in this article or reported on this one.
  • EP-A-0 059 581 discloses an article clothing like vest containing heat pipes which is connected by independent external heat pipe and a connector to a heat sink.
  • WO-A-9,213,600 also describes a vest containing an expandable heat pipe, the inner wall of the vest being in contact with the body of the wearer and forming a source zone while its outer wall forms a well zone to dissipate body heat into the atmosphere.
  • Document EP-A-305,715 describes a shoe heating with insole containing a passage extending over the entire length of the sole and having an anterior end portion extending towards the top in the front part of the shoe shell, and an upward posterior end portion in the rear buttress of the shoe.
  • the passage spanning the length of the sole has a closed circuit for circulation of a coolant in motion under the effect of the pressure exerted by the foot in motion.
  • the present invention aims at improvements brought to a shoe for heating or cooling a sensitive part of the foot without use an external source of energy by very simple means and can be incorporated very easily in such a shoe.
  • the insole contains a heat pipe extending over the entire length of the sole and having a source area receiving heat from the foot and at least one well zone constituted by a part extending upwards.
  • the heat pipe is an element heat transfer comprising, in a thin volume delimited by a sealed enclosure, a fluid to change liquid / vapor phase, such as water under tension steam.
  • the heat pipe which is an element of thermal conditioning of the article of clothing or footwear, can be integrated in this article or reported on this one.
  • Figure 1 is a schematic sectional view illustrating the thermal conditioning effect of a heat pipe incorporated in an article of clothing or footwear.
  • Figure 2 is a sectional view of a variant of the thermal conditioning element.
  • FIG. 3 is a view in vertical section and partial longitudinal view of a safety shoe comprising, in its sole, a heat pipe for evacuation heat from the foot outwards.
  • FIG. 4 is a view in vertical section and longitudinal of an alternative embodiment of the shoe shown in Figure 3.
  • FIG. 5 is a view in vertical section and schematic longitudinal view of an alternative embodiment of the shoe adapted to warm the wearer's toes.
  • FIG. 1 the principle of heat transfer which is implemented work, according to the present invention, in an article footwear or clothing.
  • item of clothing we will hear, in the description which follows, both a actual garment that any other item can be brought into contact with a part of the body, such as than a blanket for example.
  • this wall 1 which may be a thickness of fabric, a wall or a sole of a shoe, a thickness of a blanket etc ....
  • This wall 1 is in contact with part 2 of the body of the wearer of the article, part which is relatively high temperature.
  • the thermal conditioning element which is used to provide this heat transfer, is constituted by a heat pipe 3 which extends between an area source 3a, located opposite the hot part 2 of the body, and a well zone 3b distant from the source zone 3a and at from which heat Q2 is released to outside.
  • This heat pipe 3 consists of an enclosure waterproof, closed on itself, containing a fluid change of liquid / vapor phase, such as, for example, water under its vapor pressure.
  • Heat pipe 3 is relatively thin and its size is clearly exaggerated in Figure 1 to facilitate understanding of the invention.
  • the wall 4 of the heat pipe is composed of two thin sheets welded together along their edges, in a material which is a good conductor of heat such as than a charged metal or plastic metallically.
  • the thin internal volume of heat pipe 3 can be free, as shown in Figure 1, or well it can contain an inner wick 6, such as a metallic fabric, which acts both as a spacer and capillary drainage of the liquid phase.
  • the operating principle of heat pipe 3 is good known.
  • the heat, represented by the arrows Q1 produced by part 2 of the body causes, in the source zone 3a of heat pipe 3, the boiling of the fluid and the vapor as well produced moves to the cooler area or sink area 3b of heat pipe 3, where this heat is returned to the exterior as indicated by the arrows Q2.
  • the vapor condenses and the fluid returned to the liquid state returns to the source area 3a.
  • the path of the fluid inside the heat pipe 3 is indicated by arrows in Figure 1.
  • the liquid phase make-up transfer, from the well zone 3b to the source zone 3a, can be done under the effect of gravity alone and in this case heat Q1 must be provided at the lowest point of the heat pipe 3 and evacuated (heat Q2) at the highest point of the heat pipe. Any internal wick 6 is then not required in this case.
  • the liquid phase make-up transfer can also be done only by capillary route and the liquid recharge of the condensed phase, of the zone well 3b at source area 3a can be done at the same altitude and even from a level lower than the evaporation level, as illustrated on the figure 2. In this case the presence of an internal wick 6 in heat pipe 3 is essential. Finally the transfer can also be carried out jointly under the effect of gravity and capillarity and in this case wick 6 is obviously mandatory.
  • the safety shoe shown in FIG. 3, designated as a whole by the reference 7, includes a body 8, an outer sole 9, an anti-intrusion inner sole or anti-penetration and, at the rear of the rod the shoe, a rear buttress 12 for protecting the heel.
  • the anti-intrusion insole 11 contains, in its thickness, a thin heat pipe 13 which extends over the entire length of the sole and is extended by end portions 13a, 13b extending towards the top and constituting well zones.
  • the extreme part front 13a is curved backwards so that conform to the shape of a front protective shell 14 of the shoe.
  • the posterior end portion 13b extends substantially vertically in the rear buttress 12 of heel protection.
  • heat pipe 13 has two source zones located respectively below the zones of support of the plant and the heel.
  • the heat introduced in the source areas of heat pipe 13 causes boiling phase change fluid and this heat is transmitted to the anterior end portions 13a and posterior 13b of the heat pipe which constitute its well zones. Heat released to the outside in well areas 13a, 13b is evacuated by air circulation ducts provided in the walls of the shoe.
  • a first air circulation duct 15 starts from an orifice lower air inlet 16, provided in the front of the hull of the shoe, and it ends up with an air outlet 17 provided on the top of the shoe.
  • a posterior circulation duct 18 starts from an orifice lower air inlet 19, located at the base of the buttress rear, and leads to an air outlet orifice 20 located higher up in the buttress. Therefore, the air circulates, by natural convection, in the conduits anterior 15 and posterior 18, as indicated by the arrows, and it licks the anterior well areas 13a and posterior 13b of heat pipe 13 to evacuate heat to outside.
  • the anti-intrusion sole 11 is also equipped with a forced ventilation device and at this indeed it has an air circulation duct lower 21 extending over the entire length of the sole, below the heat pipe 13, and communicating, to its ends, with air circulation ducts anterior 15 and posterior 18.
  • a passage 22 is provided in the anti-intrusion sole 11, in the heel support area of the wearer, to communicate the interior of the shoe with lower circulation duct 21. This allows to use the periodic pressure of the heel of the carrier on the rear part of the anti-intrusion sole 11 to produce a pump effect favoring the air circulation below heat pipe 13 and in anterior 15 and posterior 18 circulation ducts.
  • front and rear air inlet holes 16 and 19 can be fitted with adjustable flaps which allow exhaust air pumped out when are open or the air duct to the well zones 13a, 13b of the heat pipe 13 when they are closed.
  • the shoe 7 illustrated in FIG. 3 has a heat pipe 13 with two anterior well zones 13a and posterior 13b, it goes without saying that it might not include only one of these well areas.
  • the foot cooling is possible as long as the air temperature is below temperature maximum of the skin of the foot which is of the order of 33 ° C for normal physical exercise which can reach approximately 40 ° C in the case of prolonged physical exercises (race to foot).
  • the heat transfer to the outside is adjustable. he can be strengthened, stabilized or even canceled depending on the user comfort requirements.
  • FIG. 4 represents an alternative embodiment of the safety shoe of figure 3 without pump air circulation.
  • the conduit lower 21 is not provided in the anti-intrusion soleplate 11.
  • the adjustable flaps which are provided in the lower air inlet ports 16 and 19 allow air circulation, by chimney effect, in the anterior 15 and posterior 18 conduits and they cancel this traffic when closed.
  • heat pipe 13 has the only anterior well zone 13a which is located in the immediate vicinity of the toes.
  • This well zone 13a is insulated as much as possible from the outside by the front wall of the shoe.
  • the heat Q2 emitted by the zone well 13a is represented by arrows directed towards the toes of the shoe wearer and it gets transferred by a warm, convective and radiative wall effect.
  • the anterior well zone 13a could be reported by securing the sock of the carrier by means of a hook-and-loop type device and in this case the heat transfer is additionally conductive to through the fabric.
  • the soleplate containing the heat pipe 13 may not no longer be integrated into the shoe itself but it can instead be reported inside this shoe.
  • the sole insert, containing heat pipe 13 can be placed in the shoe outside the wearer's sock so as to trap the foot like a slipper.
  • the soleplate containing the heat pipe 13 can be included inside the sock and in this case the material of the heat pipe 13 is a flexible material.
