Definitions

  • the present invention relates to a shock-absorbing sole structure which can be used in the sector of footwear intended to protect the spine from injury which may occur during walking, or running in the case of sports footwear.
  • Footwear has for some time been known which forms on the sole or inside thereof a cushion constituted by a fluid, for example air or gas, to produce the shock-absorbing effect.
  • a fluid for example air or gas
  • the main disadvantage is represented by the fact that the cushion is exposed to the risk of damage by external agents, such as nails, sharp stones or objects which may be on the ground and which may cause puncturing of the cushion with inevitable leakage of the working fluid and total loss of functionality by the same cushion.
  • Another disadvantage is represented by the low support effect on the foot by the working fluid in that the latter is provided in the cushion generally at atmospheric pressure, so as to simplify the construction of the sole.
  • some traditional shock-absorbing sole structures provide a pressurised fluid inside the cushion, however this means that in any case a compromise has to be reached between the required pressure of the fluid and the complexity of the construction of the sole structure which has to guarantee the hermetic seal of the cushion. Moreover there is a natural leakage in time of the gases, which tend to leak from the walls which contain them, making the stock of footwear unusable.
  • the object of the present invention is therefore that of providing a shock-absorbing sole structure, for both classic and sports footwear, which remedies the disadvantages suffered by the known art, and has the requirements of simplicity of filling of the cushions by means of air or gas, yet with sealing of the solid parts.
  • More particularly one object of the present invention is that of providing a sole structure without the possibility of damage to the shock-absorbing system, during normal use of the footwear.
  • Another object of the present invention is that of creating a shock-absorbing sole structure capable of producing a significant effect of support of the foot without thereby complicating the construction of the sole.
  • Yet another object of the present invention is that of providing a simple and economical shock-absorbing sole structure.
  • a shock-absorbing sole structure of the type comprising: a tread in turn having a heel cavity and a sole cavity on the side of the upper surface of the tread, a heel protuberance and a sole protuberance on the side of the lower surface of the tread, corresponding to the heel cavity and to the sole cavity respectively; and a layer for covering the heel cavity and the sole cavity superimposed and fixed on the upper surface of the tread, characterised in that it comprises elastic shock-absorbing means inserted in the heel cavity and respectively in the sole cavity, in the form of a cushion made in any solid material having an elastic behaviour similar to air.
  • Materials suitable for the purpose may be foam rubber or latex foam.
  • the elastic shock absorption element is formed by a solid material which, unlike an air cushion, is capable of retaining good functionality in the case of puncturing of the heel and/or sole cavity by an external sharp body, and of not losing pressure in time or due to a minor assembly defect of the sole, not visible to the naked eye, but which causes rejection of the entire footwear, with a considerable financial waste.
  • the shock absorption system of the present invention ensures a higher shock absorption effect than that produced by air, considered as an ideal fluid from the point of view of simplicity, but which does not absorb the waves of impact and the vibrations which instead a solid spongy material can do.
  • the shock absorption system of the present invention therefore has the merit of creating ideal shock absorption as it is made with a material having an elastic behaviour equivalent to air, without having the disadvantages of an air and more generally fluid shock absorption system, given that the shock-absorbing cushion in a solid material of the present invention continues to perform its shock-absorbing effect even in the case of damage to its housing cavity, and in that due to the integration of the solid cushion of the present invention in the sole structure it is not necessary to form a hermetically sealed housing which is instead essential for air and more generally fluid shock-absorbing systems.
  • shock-absorbing sole structure of the present invention is extremely simplified, with only the need to insert and block the solid shock-absorbing cushion between the internal wall of the cavity and the lower surface of the covering layer.
  • Another significant advantage of the present invention is that it is possible to regulate the action of support of the foot, designing according to the weight to be supported the density and/or height of the layer of shock-absorbing material and consequently of the relative sole and heel cavity.
  • the shock-absorbing sole structure comprises a tread 1 provided on the upper surface with a heel cavity 3 and a sole cavity 5 in turn defining on the lower surface of the tread 1 a heel enlargement 7 and a sole enlargement 9.
  • the sole cavity 5 has an elongated shape and is arranged immediately behind the metatarsal region of the foot, where the action of the front part of the foot is concentrated.
  • the interior of the heel cavity 3 and sole cavity 5 respectively is filled with high density foam rubber 11t and 11p respectively, that is to say a solid shock-absorbing filling material which is preferable due to its elastic behaviour similar to air.
  • a covering element 13 is applied which has on the lower surface a layer of adhesive to be applied to the upper surface of the sole 1 in such a way as to restrain the foam rubber cushions 11t and 11p in the respective cavities 5 and 3.
  • the covering element 13 has a shape identical to the sole but with slightly smaller dimensions, in such a way as to leave a perimetral strip 15 of tread 1 uncovered for application of the upper (not shown).
  • shock-absorbing cushion in the heel cavity 11t it is merely sufficient for them to be made in a solid material with elastic behaviour similar to air.
  • the sole structure prefferably be made with a cavity to be filled with elastic material, deep to the extent the load to be damped is high.
  • the element of covering is a wedge 13' which has a sufficient thickness so that cavities 33 and 55 can be formed, on the side of its lower surface, which face corresponding cavities 3' and 5' on the tread 1' in such a way as to enclose a space for housing the shock-absorbing cushion 11't and 11'p which is approximately double compared to the case described previously.
  • the embodiment of the sole structure of Fig. 4 has the additional advantage of using an element already present in the normal construction of the shoe, that is to say the wedge, to block the cushions in position.
  • the lower part of the tread 1 is provided with a system of stabiliser elements.
  • the stabilisation elements are represented by a pair of arched protuberances 17 positioned outside of the opposite end side portions of the sole cavity 5 and by a pair of arched protuberances 19 positioned outside of the opposite end side portions of the heel cavity 3.
  • the protuberances 17 and 19 have a slightly lower height than that of the enlargements 7 and 9 of the tread in such a way as to allow equilibrium of the sole without penalising its shock-absorbing capacity.
  • the stabilisation system could comprise additional side protuberances or side protuberances of a different shape from those illustrated hitherto but always surrounding as a minimum the opposite side ends of the heel cavity 3 and sole cavity 5.
  • the stabilisers can also be formed by elements materially and structurally similar or identical to the cushions of the present invention, in this latter case possibly also having a height equal to that of the enlargements 7 and 9 of the lower surface of the tread.
  • Figs. 6 and respectively 7 show a variant of the shock-absorbing sole structure of the present invention, wherein the shock absorption elements 11"'t and 11"'p and respectively 11""t and 11""p can be removably inserted in the body of the sole.
  • the housings of the shock-absorbing elements are formed by cavities transversely extended in relation to the sole and open at the opposite ends in such a way as to allow manual pressure insertion of the shock-absorbing elements.
  • Fig. 6 which illustrates a classic sole structure and therefore of minimal thickness
  • covering element 13"' is smooth and heel 3''' and sole 5"' cavities for housing the elastic material are placed on the tread 1'''.
  • sole structure in Fig. 7 comprises a wedge 13"" of thickness such as to allow shaping on the lower surface thereof of a heel cavity 333 and a sole cavity 555 corresponding to the sole cavity 3"" and heel cavity 5"" of the tread 1"", in such a way as to double, compared to the previous case, the space available for the shock-absorbing elastic material.
  • the process of construction of a shoe using the shock-absorbing sole structure of the present invention involves a first phase wherein the tread is moulded with the tread cavities and any stabiliser elements, a second phase wherein the elastic cushions are inserted and blocked in the sole and heel cavities by gluing the covering layer or wedge or simply by fitting the cushions in the respective cavities, and finally the last phase wherein the upper is mounted on the peripheral strip of the upper surface of the sole.
  • shock absorption elements which can be inserted removably in the sole, the insertion can be carried out manually when assembly of the shoe has already concluded.
  • the shape and number and arrangement of the heel and sole cavities and of the elastic cushions inserted therein can also be different from those shown hitherto, without thereby departing from the basic concept underlying the invention which is that of providing a shock-absorbing structure made by inserting and blocking in position in appropriate cavities of the tread a series of cushions in a solid material, having an elastic behaviour similar to air, in such a way as to support the foot, damping those stresses transmitted thereby to the sole which may be damaging to the health of the spine.
