Definitions

  • the present invention relates to an outer shoe sole, either with or without a heel, which is designed so as to permit the front andrear parts thereof to be twisted relative to each other.
  • the narrowest part of the shank area of the sole has a width which'is even smaller than the narrowest part of the arch of the foot,-as seen upon the bottom thereof.
  • the parts of the upper which are drawn toward and into the constricted shank area of the sole are therefore fully exposed to the dirt on the ground and are quickly soiled, especially in bad weather, and consequently these parts are also subjected to stronger wear and quicker aging than all other parts of the upper.
  • shoes with soles of this type are very desirable because of the flexibility of the shank area which permits the front and heel portions to be twisted relative to each other.
  • the sole according to the invention is designed so that the upper surface of the shank area of the sole has a width substantially equal to the width of the arch of the foot on which the shoe carrying the sole is to be worn, while underneath this upper surface the outer and inner edges of the shank area are reduced in thickness and are recessed and curved inwardly toward each other so as to form an S-shaped or Z-shaped central part which has a relatively small width at its narrowest portion.
  • the central part of the shank area of the sole has a greater thickness than the two lateral parts.
  • the lateral parts of the shank area of the sole adjacent to the outer and inner edges thereof should therefore be very thin and their thickness may amount, for example, to no more than 1 mm. If the sole consists of rubber or the like, such thin parts may be easily produced. Insofar as the invention is concerned, however, it is immaterial whether the sole, either with or without a heel, is made of two layers which are secured to each other or of one 3,366,117 Patented Jan. 30, 1968 layer which is recessed at the shank area by reducing its thickness at both sides of its central portion by grinding or cutting, or whether the sole is molded in the desired shape as one integral element in one operation.
  • the thickness of the central part of the shank area should also be relatively small and amount, for example, to 3 to 4 mm, and in any event it should not be greater than the thickness of the front part of the sole and also of the rear part if the latter is not molded integrally with a heel.
  • the bottom layer that is, the actual outer sole
  • the upper layer facing the bottom of the foot may be made of a more elastic material, for example, rubber, especially since this layer is usually covered by an insole which is also designed so as to permit its rear part to be easily twisted relative to its front part.
  • the sole according to the invention may even be made of three layers, namely, of the two mentioned layers and an outer half sole which has a size in accordance with the part of the sole in front of the shank area.
  • FIGURE 1 shows aplan view upon the lower side of a sole with a heel thereon;
  • FIGURE 2 shows a cross section which is taken along the line II.-II of FIGURE 1; while FIGURE 3 shows a cross section which is taken along the line IIIIII of FIGURE 1 when the front part of the sole is provided with a half-sole the rear end of which is indicated in FIGURE 1 by a dotted line.
  • the drawing illustrates a sole according to the invention which is intended for a left shoe.
  • the front part of the new 'sole in indicated at 1, the rear or heel part at 2, and the shank area intermediate these parts at 3.
  • the inner and outer edges 4 and 5' of the bottom or tread surface of the sole are recessed relative to the inner and outer edges 4 and 5 of the upper surface thereof and they are curved strongly inwardly toward the central part 6 so that this bottom surface of the shank area 3 of a sole for a left shoe is substantially Z-shaped, while that of a sole for a right shoe is substantially S-shaped.
  • the upper surface of the shank area 3 of the sole has such a curvature and width that the inner and outer edges 4 and 5 thereof correspond substantially to the outlines of the arch portion of the foot on which the shoe carrying this sole is to be worn, as seen in a plan view upon the bottom of the foot.
  • the central part of the shank area 3 which is defined by the edges 4' and 5 has therefore a considerably greater thickness than the lateral parts which are defined by the edges 4 and 5.
  • the thickness of this central part should, however, be equal to or even slightly smaller, but never greater than the thickness of the front part 1 of the sole and it may amount, for example, to 3 to 4 mm., while the thickness of the lateral parts may be as little as, for example, 1 mm. In any event the thicknesses of the central and lateral parts of the shank area should be such that the rear part 2 may be easily twisted relative to the front part 1 of the sole.
  • the outer sole according to the invention may consist of one integral piece of material, as indicated in FIGURE 2, at least its shank area 3 may also be made of two layers of material which may be secured to each other, for example, by gluing.
  • the outer sole may, however, also consist of three layers, as indicated in FIGURE 3.
  • a half sole 8 which extends up to the dotted line 7 at the front end of the shank area 3 is secured upon the front part 1 of the sole.
  • the sole is made of a single piece of material, for example, of leather or rubber
  • the reduced lateral portions of the shank area 3 may be attained by cutting or grindingor, if'it consists of rubber, it may be molded in the desired shape in one operation.
  • An outer sole having front and rear parts and a shank portion intermediate said parts, said front and rear parts adapted to be twisted relative to each other about said shank portion, said shank portion comprising ,a plurality of superposed layers, the uppermost of said plurality of layers being of a width approximately twice the width of the lowermost of said plurality of superposed layers at the narrowest part of said lowermost layer, the central partof said shank portion having a sharply curved cross section and the thickness of said central part being not greater than the thickness of said front part and the thickness of said rear part of the outer sole.
