Definitions

  • This invention relates to an insole for providing ventilation to a foot in a shoe.
  • absorbent insoles of one sort or another.
  • One type of absorbent insole includes activated carbon to absorb the perspiration and in particular the matter giving rise to undesirable odours. Although these products may reduce the effects of perspiration, they do not reduce its cause, and because of their limited volume, the absorbent insoles require frequent replacement.
  • a removable insole for insertion into a shoe, the insole comprising means responsive to the walk ⁇ ing action of the wearer of the shoe for drawing air from one part of the shoe and for discharging the air at another part of the shoe, thereby caus- ing circulation of air over at least a part of the wearer's foot within the shoe.
  • the pump comprises a resiliently compressible chamber within the insole, whereby, as the wearer puts his or her weight on the shoe during walking, the chamber is compressed, expelling air therein through the outlet, and as the shoe is lifted off the ground, the chamber expands back to its original shape, drawing the next charge of air into the chamber.
  • the air outlet is suitably located at the region of the insole beneath the wearer's toes. Further outlets may be positioned to coincide with other regions of the wearer's foot, in use.
  • the flow of air induced by the insole in the shoe will tend to pass around the wearer's foot and to escape upwardly around the ankle, or through ventilation holes provided in the shoe uppers, for example, carry ⁇ ing away excess heat and water vapour.
  • the cooling effect will reduce the tendency of the foot to perspire, while the removal of water vapour will further reduce the risk of attack by fungal infections, by removing the conditions which favour their growth. Since the flow rate is dependent on the walking action of the wearer, the faster the rate of stepping, the greater is the air flow rate generated.
  • the compressibility of the insole provides a cushioning effect, increasing the comfort of the wearer.
  • Figure 1 is an outline view of a shoe into which an insole according to a first embodiment of the invention has been fitted;
  • Figure 2 is a plan view of the lower layer of the insole of Figure 1;
  • Figure 3 is a plan view of the upper layer of the insole;
  • Figure 4 is an enlarged vertical section through one type of valve which can be used in the insole of Figure 1;
  • Figure 5 is a perspective view of another type of valve
  • Figures 6, 7 and 8 are exploded perspective views of three alterna ⁇ tive forms of insole
  • Figures 9 to 12 are diagrammatic sectional elevations of the insole of Figure 6, showing the successive stages in the operation thereof within a shoe. Detailed Description of the Illustrated Embodiments
  • the shoe 1 illustrated is, by way of ex ⁇ ample, a sports shoe, into which has been introduced an insole 2 consist ⁇ ing of lower layer 3 provided with a plurality of resiliently-compressible nodules 4 upstanding therefrom, the lower layer 3 being sealingly at- tached to an upper layer 5 so as to form between the layers 3 and 5 a closed chamber 6, sealed at the periphery thereof.
  • the upper layer 5 is provided, in the region thereof corresponding to the position of the toes, when worn on the user's foot, with an aperture 7 communicating with the chamber 6 and covered with a rubber flap 8 which is sealed to the upper surface of the upper layer 5 around the aperture 7 leaving a minor portion of the circumference of the flap 8 unattached, so that the flap can act as a non-return valve, allowing air to leave the chamber 6 and flow into the interior of the shoe, but not allowing air to return from the interior of the shoe to the chamber.
  • the nodules 4 are formed of a material sufficiently deformable to enable them to collapse upon themselves when the wearer's weight bears upon them, but sufficiently resilient to ensure that they return to their original height as soon as the weight is removed.
  • the shape of the nodules is suitably such as to assist them in collapsing verti ⁇ cally, rather than simply folding sideways.
  • the nodules may suita ⁇ bly be formed as cones, for example of an expanded elastomeric material such as natural or synthetic rubber.
  • the nodules are preferably attached at the uppermost points to the underside of the upper layer 5, for example by an adhesive, or by a welding process.
  • a flexible tube 10 is sealed into the end of the insole 2 so as to communicate with the chamber 6 therein, and extends upwardly to open at a point outside the shoe and sufficiently ele ⁇ vated to ensure that the opening remains clear of water, for example from puddles and the like, in use.
  • the tube 10 may be provided at the upper end thereof with a non-return valve, admitting air to the upper end of the tube, but preventing its escape therefrom, or the valve may be incorpo- rated into the chamber 6 within the insole 2.
  • the structure of possible valves is described hereinafter with reference to Figures 4 and 5.
  • the pressure of the foot on the upper layer 5 of the insole compresses the nod ⁇ ules 4, thereby reducing the volume of the chamber 6 and increasing the pressure of the air therein.
  • This causes the non-return valve in the tube 10 to close, preventing the air from flowing out of the tube.
  • the excess air pressure in the chamber therefore causes an escape of air into the shoe interior via the aperture 7, the flap 8 being lifted by the air flow.
  • FIG. 4 shows a simple flap valve which can be fitted into the up ⁇ per end of the tube 10.
  • the valve consists of a short plastics tube 11 hav ⁇ ing a spaced pair of circumferential ribs 12 which provide a sealing fit in the end of the tube 10 and which space the tube 11 inwardly thereof.
  • the lower end of the tube 11 is provided with a hinged closure flap 13 inte ⁇ grally moulded therewith so as to be biased towards a position in which it closes the end of the tube 11. Excess pressure within the tube 10 holds the flap 13 against the end of the tube 11, thus preventing outward flow of the air, while lowered pressure within the tube 10 opens the flap 13 as air flows in.
  • FIG. 5 An alternative simple valve is shown in Figure 5.
  • the tube 10 is provided with a resilient flattened end 14 which, in use, will be located within the chamber 6. Excess pressure within the chamber 6 holds the flattened end 14 closed, preventing escape of air back into the tube, while reduced pressure causes the air in the tube 10 to flow into the chamber, forcing the flattened end 14 open.
  • the insole shown in Figure 6 consists of a self-skinned open-celled plastics compressible foam layer 60, whose outer skin is substantially im ⁇ pervious to air.
  • the foam is such as to recover its fully expanded form rapidly upon release of compressive forces therefrom.
  • four relatively large holes 62 are punched through the foam layer 60, while in the region of the toes, a series of small holes 63, each compa ⁇ rable in size with a pin hole, is punched through the foam layer 60 adja ⁇ cent to the edge of the insole.
  • a permeable "comfort layer” 64 whose function is to separate the sole of the foot from the skin of the foam layer 60, is bonded to the upper surface of the foam layer 60.
  • the operation of the insole is described hereinafter in more detail with reference to Figures 9 to 12.
  • Figure 7 shows an alternative construction, in which, in place of the permeable "comfort layer” 64, a non-porous comfort layer 70 overlies the foam layer 60.
  • a non-porous bottom layer 71 is also provided, so that the foam layer 60 is sandwiched between the two non-porous layers 70 and 71. These layers are punched with the foam layer 60 to form the holes 62 and 63.
  • the operation of this insole is generally the same as that of the insole shown in Figure 6.
  • the insole shown in Figure 8 consists of a layer 80 of closed cell resiliently compressible plastics foam having moulded into the underside thereof a plurality of channels 81, each of which extends from the heel region 82 along the length of the insole to open at the edge of the insole in the region of the toes, the channels 81 fanning out to distribute air evenly in this region.
  • the channels are narrower and closer together, since the downward pressure of the foot in this region is generally considerably less than in the heel or toe regions.
  • a "comfort layer” 84 of fabric feel material is bonded to the upper surface of the foam layer 80.
  • An additional non-porous layer may be bonded to the underside of the foam layer 80, if desired.
  • the action of walking generally results in pressure being applied by the foot alternately to the heel region and the toe region so that, as the foot is lifted the foam layer regains its shape and draws air into the channels 81.
  • the heel returns to the ground, air is expelled from the channels in this region, some of which is driven forwardly along the channels, through the restrictions formed by the narrowing in the instep and into the toe region.
  • the whole foot is pressed on the ground and the weight of the person is transferred to the ball of the foot, air is expelled from the toe region. Because of the restric ⁇ tions in the instep region, the greater part of the air is expelled from the periphery of the insole to circulate over the toes.
  • Figures 6 and 7 can be seen to be similar to that of the insole described with reference to Figure 8.
  • the insole is shown exaggeratedly thick, by comparison with its length, for the sake of clarity.
  • Figure 9 shows the end of a step, in which the heel region 61 comes into contact with the ground first, causing the heel to block the holes 62. As the remainder of the foot is pressed on to the ground, tending towards the position shown in Figure 10, the foam layer 60 becomes compressed, expelling air therein. Because the larger holes 62 are blocked, the only escape for the air is through the small holes 63 around the toe region, circulating air around the toes.
