Definitions

  • the present invention generally concerns a shoe sole having a dynamically shock-absorbing structure, but above all a shoe sole providing a dynamic pronation support.
  • the shoe sole is particularly suitable for sport shoes and may be used for instance for running on hard surfaces. It may also be used in e.g. walking boots, working shoes, in principle in all types of footgear. It may also be designed as a separate insole to be placed inside the shoe it is designed for.
  • the foot In walking and running, the foot has to bear con ⁇ siderable weight corresponding to several times the body weight, each time it is set down into contact with the ground or the surface underneath.
  • the cushion of fat found for instance in the heel dampens the impact upon heel strikes, that is the phase of the walking cycle when the heel is set down into contact with the surface underfoot.
  • the main weight is on the longitudinal arch of the foot (the arch extending lengthwise on the inner side of the foot), resulting in deformation of this arch which plays an important part of the energy absorption.
  • the feet pronate, i.e. the outwards margin of the foot is turned outwards-upwards as the foot is set down on the ground or the support.
  • An increase of the pronation results in an increase of the weight on the longitudinal arch of the foot and conse ⁇ quently a higher risk of overstraining, which in turn may be the cause of permanent deformation of the arch.
  • Sport activities expose the body to considerable stress and strain.
  • large parts of the skeleton must bear considerable weight, a condition which is aggravated for instance by excess pronation, and which may lead to injuries on the lower extremities and in the back.
  • Such injuries may occur as a result of long-standing and repeated weight bearing, as is the case with for instance long-distance runners, or may be caused by isolated instances of heavy but unsuitable exposures to weight bearing, such as may be experienced e.g. in triple jumping.
  • Shoes for sport uses therefore should have a sole which is able to absorb and cushion as far as possible the shocks and the load produced as the foot is set down into contact with the ground.
  • the purpose of the present invention thus is to provide a shoe sole of a construction that is capable of providing satisfactory shock absorption while at the same time giving the longitudinal arch of the foot a dynamic pronation support.
  • the shoe sole in accordance with the invention is formed with a first chamber and a second chamber arranged in the sole and completely or partially filled with a fluid, and with a channel inter- connecting said chambers, said channel arranged, upon compression of one of the chambers, e.g. the first chamber, to transmit fluid from said first compressed chamber to the second one of said chambers for expansion of said second chamber, or vice versa, said first chamber being positioned essentially only underneath the heel portion of the foot.
  • the second chamber is positioned essentially only underneath the longitudinal arch of the foot and in that due to the compression of the first chamber when the latter is activated by the heel portion, said second chamber fills with fluid and expands, lifting the longitudinal arch immediately prior to said arch absorbing the load and thereafter being deformed. In this manner the arch of the foot receives a dynamic support during the deformation which is gradually dampened.
  • FIG. 1 schematically in a longitudinal section view illustrates a shoe fitted with a sole in accordance with the invention in the heel-strike phase of walking or running, i.e. when the heel portion is set down into contact with the ground.
  • Fig. 2 is a cross-sectional view along line II-II of Fig. 1.
  • Fig. 3 is a view similar to Fig. 1 but illustrates the heel elevation phase of the cycle, i.e. when the rest of the foot is set down into contact with the ground but the heel portion is lifted.
  • Fig. 4 illustrates schematically in a perspective view obliquely from above the shoe sole in accordance with Figs. 1 and 3, showing in closer detail the position of the chambers formed in the sole.
  • the shoe sole illustrated in the drawing figures indicated generally by reference 1 comprises a sole 2 to be described in closer detail in the following, uppers 3 and an insole 4.
  • the shoe is shown worn on a foot 5.
  • the sole is formed with a first chamber 6 and a second chamber 7, the first one of which, 6, being positioned essentially only underneath the heel portion 8 of the foot 5 whereas the second chamber 7 is positioned essentially only underneath the longitudinal arch 9 of the foot 5.
  • the first and the second chambers, 6 and 7, respect ⁇ ively, are completely or partially filled with a suitable fluid 10, such as a gas och. a more or less viscous liquid.
  • a suitable fluid 10 such as a gas och. a more or less viscous liquid.
  • the chambers 6 and 7 are interconnected by means of an interconnection channel 11 which is arranged in the interior of the sole 2 and which may be formed by two or several branch channels. Via the interconnection channel 11 the fluid 10 may be transferred from one channel to the other, i.e. upon compression of chamber 6 it is transferred to chamber 7 to expand the latter, and reversely.
  • the second chamber 7 Upon expansion of the second chamber 7 due to the compression of the first chamber 6 as the latter is affected by the heel portion 8 of the foot 5, the second chamber 7 acts as a dynamic pronation support underneath the longitudinal foot arch 9, whereby, when the latter is exposed to load as a result of the foot hitting the ground, said second chamber 7 will be compressed followed by expansion of the first chamber 6 via the interconnection channel 11.
  • the second chamber 7, in its expanded condition, will impart to the portion 12 of the sole 2 that is contiguous with the longitudinal arch 9 a configuration conforming to the natural shape of the longitudinal arch 9 of the foot in the non weight-bearing condition of the arch.
  • the latter may be formed in one or several of the branches thereof with a throttling means, not shown, e.g. in the shape of a constriction of the channel and/or an adjustable throttling valve.
  • an external connection fitting may be provided for at least one of the chambers 6, 7 and/or for the interconnection channel 11.
  • the external fitting could comprise a non-return valve or similar means in the edge portion of the sole 2, said non-return valve being connected to the associated one of chambers 6, 7 and/or to theinterconnection channel 11 via a connecting passageway.
  • the interconnection channel 11 which as mentioned previously may be formed from two or several part or branch channels also the first and/or the second chambers 6 and 7, respectively, could of course be divided into two or several part chambers to vary the qualities of the shoe 1 or of the sole 2.
  • the sole 2 may thus be made more or less resilient and its shock- absorbing and supporting effect be made larger or smaller.
  • the invention should of course not be regarded as limited to the embodiment illustrated in the drawings and referred to in the aforegoing but may be modified in a variety of ways within the scope of the appended claims.

Abstract

Une semelle de chaussure (2) comprend une première (6) et une deuxième (7) chambres remplies complètement ou partiellement d'un fluide (10) et reliées par une conduite de connexion (11) permettant à ce fluide (10), lorsqu'il est comprimé dans l'une des chambres (6, 7), de passer dans l'autre pour la dilater. La première chambre (6) est placée pour l'essentiel sous le talon (8) du pied (5) alors que la deuxième (7) se trouve pour l'essentiel sous la voûte plantaire (9) du pied (5). Quand la deuxième chambre (7) se dilate du fait de la compression de la première chambre (6) par le talon (8), cette deuxième chambre constitue un support de pronation dynamique situé sous la voûte plantaire (9). Lorsque cette voûte supporte un poids, ceci comprime la deuxième chambre (7).
