Definitions

  • Striker ABSTRACT An article of footwear has uppers which may in form [30] Foreign Application Priority Data June 20, 1970 70 23 2574 of straps, and a sole of yieldable elastomeric material which is provided at least on its upper and, according to some embodiments, on its lower surface with pro- [52] US. 128/582 [51] Int. Cl. 3/12 36/115, 43, 8.1; 128/581,
  • the projections which extend substantially normal to the general plane of the respective surface.
  • the projections may be of different length.
  • the present invention relates generally to an article of footwear, and more particularly to the construction of a sole member in such an article of footwear.
  • Sole members of the type in question are already known, especially for use in sandles. However, they are also known as innersoles which can be worn in regular shoes other than sandles. In either case, however, the purpose is to provide a sole member having elastic projections which engage the underside of the foot of a wearer and during walking in effect will massage the foot, providing improved circulation and generally facilitating the well-being of a user.
  • the known constructions utilize either synthetic plastic material or rubber and have a smooth underside which may or may not be connected with an essentially rigid carrier sole, for instance consisting of wood.
  • the known projections have a relatively high resistance to deformation in their longitudinal direction, that is in vertical direction, but they are relatively unresistant to lateral deflection. Even if they are made quite thick relative to their length, this does not change especially if the projections are provided on a sole member of rubber or analogous elastomeric material, because at their base they are of course still elastically anchored in or of one piece with the actual sole member and thus can yield. It is also necessary to consider that the height and the thickness of such projections must remain within certain limits if sufficient massaging action on the foot is I still to be obtained.
  • a concomitant object of the invention is to provide such an improved article of footwear which provides for proper and even support and massaging of the foot of a wearer.
  • a concomitant object of the invention is to provide such an improved article of footwear which is relatively inexpensive to produce and therefore to sell.
  • an article of footwear comprising upper means, and sole means of yieldable elastomeric material provided on the upper means and including a sole member having a normally upper surface adapted to face the underside of a human foot.
  • the sole member is provided with a plurality of projections of different heights which are distributed over the surface thereof and which project upwardly from this surface so as to extend at least substantially normal to the underside of a foot on which the article is worn.
  • the present invention is based on the realization that a proper and even massaging of the underside of a human foot can be obtained only if the profile defined by the upper ends of the various upwardly directed projections corresponds as closely as possible to the profile of the underside of the foot so that not only the middle portion of the foot is supported on the projections but may extend upwardly'almost normal to the underside of the foot but slightly inclined inwardly, whereas in the portion surrounded by the marginal circumferential portion the projections may extend completely normal to the underside of the foot.
  • the underside of the sole member itself may be smooth.
  • the sole member be flexible both in its longitudinal and in its transverse direction so that it can readily adapt itself to variations in the ground in order to assure that the projections depending upon flexing of the sole memberwill move towards and away from one another constantly and provide a constant and intensive massaging effect over the entire underside of the human foot without concentrating on unvarying individual points.
  • the underside of the sole member may be provided with additional projections which extend downwardly and each of which is coaxial with -that is an axial extension of one of the upwardly extending projections.
  • These downwardly extending projections are so deflected apart when a weight comes to bear upon the sole member, that the upwardly extending projections will be correspondingly deflected during walking, resulting in an improvement of the massaging effect obtained.
  • each of the downwardly directed projections has the same length as the respectively coaxial upwardly extending projections.
  • the profile defined by the downwardly extending projections will be identical or nearly identical with the profile defined by the upper ends of the upwardly extending projections.
  • the projections are distributed over the surface area of the sole member in accordance with the anatomic contour of the underside of a human foot, being of different lengths in accordance with the dictates of this anatomic contour.
  • these projections which are located in the marginal circumferential regions of the sole member at the upper side thereof may be shorter than the anatomic contour of the foot underside would normally require because the length of the upwardly extending and coaxial downwardly extending projections is additive, meaning that the longer projections in the marginal circumferential region of the sole member are deflected to a more substantial extent --when weight rests on themin upward direction by the downwardly extending projections than those of the inner or center portion at whose underside the projections are shorter, just as they are at the upper side thereof.
  • the sole member is made flexible.
  • the projections are constantly deflected towards and away from one another when the user walks, both longitudinally and transversely of the sole member, and this results in the desired even and uniform massaging effect without concentrating on particular pressure points at the underside of the foot.
  • This edge portion may be at least substantially circumferentially continuous.
  • FIG. 1 is a perspective view of a sandal embodying the present invention
  • FIG. 2 is a side view as seen from the right-hand side of FIG. 1;
  • FIG. 3 is a section taken on line IIllII of FIG. 2, showing the sandal with weight resting on the projections;
  • FIG. 4 is a section analogous to FIG. 3 but illustrating another and simplified embodiment of the invention.
  • FIGS. 1-3 the article of footwear per se is identified with reference numeral 1 and here illustrated as a sandal. It is preferably composed of high-molecular synthetic plastic foam or cellular material, such as polyurethane foam, or of an elastic cork-latex mixture.
  • the sole member is formed of one piece with two straps 2 which constitute the upper means in the illustrated embodiment.
  • the upper side of the sole member is provided with upwardly directed projections 3 which are distributed over the surface of the upper side and are of different heights in accordance with the anatomic contour of the underside of the foot of a human being.
  • the sole member is provided with a substantially circumferentially continuous edge portion 4 which in the illustrated embodiment projects both slightly above and slightly below the sole member and is interrupted only where the sole member 5 merges with the strap members 2 which in the illustrated embodiment are identical on their upper side and their lower side.
  • FIG. 2 shows that in the illustrated embodiment there are further provided substantially parallel downwardly extending projections 13 at the underside of the sole member 5, each of them being coaxial with one of the upwardly extending projections 3.
  • Each of the projections 13 has the same length as its respectively coaxial projection 3 so that the sandal l is identical at its upper side and at its lower side, and in the illustrated embodiment it will be seen that this identity extends also to the configuration of the edge portion 4 and to the appearance and configuration of the two opposite major sides of the straps 2.
  • FIG. 3 The section in FIG. 3 is taken through the embodiment of FIGS. 1 and 2 to illustrate the same in loaded condition, that is when the weight of a human body rests on it. It will be seen that the projections 3a which are located in the margin circumferential zone of the sandal are deflected upwardly substantially more strongly by their lower counterparts 13a, than the shorter projections 3b which are located inwardly in the portion of the sandal which is surrounded by this outer marginal circumferential portion.
  • All of the projections 3 and 13 are deflected when weight rests upon the sandal 1- both longitudinally and transversely of the sandal during walking movements, so that the underside of the foot of a wearer is constantly and evenly massaged by constantly changing engagement of the various projections with different portions of the underside of the foot.
  • the transverse movements of the projections 3, 3a and 3b resulting from the support of the differentially long projections 13, 13a and 13b constantly varies the point of contact of the projections 3, 3a and 3b with the underside of the foot, but despite this the projections 3, 3a and 3b will nevertheless extend at all times at least substantially normal to the underside 6 of the foot which transmits pressure to them. This means that the projections are always predominantly subjected to longitudinal pressure, rather than to flexing in lateral direction.
  • the straps 2 may be provided with suitable closure means, such as buckles or the like, by means of which their free ends are connected after they have been placed about the human foot.
  • the embodiment illustrated in FIG. 4 differs from the preceding embodiment in that the projections 3a which are provided in the marginal circumferential portion at the upper side of the sandal are somewhat inwardly inclined.
  • the length of the projections 3a is necessarily limited if they are not to be too readily deflectable, so that this construction is feasible only for smaller shoe sizes, whereas the embodiment in FIGS. 1-3 can be used for all shoe sizes, and also for particularly large shoe sizes as well.
  • the embodiment according to the present invention in which the projections on the underside and the projections on the upperside of the sole member are configurated identically, has the additional advantage that one and the same tool can be used for producing both the sole member and projections for the left foot as well as for the right foot.
  • the straps 2 are preferably of one piece with the sole member, if the article of footwear is to be used as a sandal, but of course the sole member with the projections can be utilized in a manner other than as a sandal, that is without the straps.
  • An article of footwear comprising upper means; sole means of yieldable elastomeric material provided on said upper means and including a sole member having a normally upper surface adapted to face the underside of a human foot and a normally lower surface facing away from the human foot; and a plurality of first substantially cylindrical projections of different heights distributed over said upper surface and projecting upwardly therefrom so as to extend at least substantially normal to the underside of a foot on which said article is worn, and a plurality of second substantially cylindrical projections provided on said lower surface and extending downwardly therefrom, all of said projections being yieldable in all directions.
  • said upper means comprising straps of one piece with said sole means and having free end portions, and connecting means for connecting said free end portions when said straps have been placed about a foot.
  • An article of footwear comprising upper means; sole means of yieldable elastomeric material provided on said upper means and including a sole member having a normally upper surface adapted to face the underextending downwardly therefrom in at least substantial parallelism with each other, each of said second projections being coaxial with one of said first projections.
  • each of said second projections has a length corresponding to that of the first projection with which it is coaxial.
