Definitions

  • the present invention relates to an upper having a sponge member in a heel portion.
  • Shoes having a sponge member in the heel portion in order to improve the fit of the heel portion of the upper are well known in the art.
  • U.S. Patent No. 3,693,270 discloses a structure of an upper for improving a fitting property of a heel portion of the upper of a shoe.
  • Said upper comprises a pad which includes a medial side portion covering a medial side of a calcaneal bone and a lateral side portion covering a lateral side of the calcaneal bone.
  • FIGS. 1A and 1B a large number of markers M were attached to the foot of the subject in a five-by-five matrix pattern.
  • FIGS. 1C and 1D show images of the markers M in a standstill position. Note that the markers M are connected with one another by vertical lines and horizontal lines so as to make the images easier to view.
  • FIGS. 2(a) to 2(e) ran as shown in FIGS. 2(a) to 2(e) , and images of the markers M were captured at different phases, including heel contact HC of FIG. 2(a) , foot flat FF of FIG. 2(b) , mid stance MS of FIG. 2(c) , heel rise HR of FIG. 2(d) , and toe off TO of FIG. 2(e) .
  • FIGS. 2(f) to 2(j) show images on the back side
  • FIGS. 2(k) to 2(o) show images on the lateral side.
  • M1 denotes a marker attached to the medial ankle
  • M2 denotes a marker attached to the lateral ankle.
  • FIGS. 2(k) to 2(o) while focusing on the back side of the foot, one will notice that the portion posterior to the lateral ankle, i.e., the area of the Achilles tendon, is narrowed increasingly toward the top over the period of heel contact HC to heel rise HR , but the narrowing decreases dramatically at the moment of toe off TO.
  • the area Fb at generally the same level as on the lateral side of the foot is narrowed throughout the entire period. It is assumed that this area Fb is behind the calcaneal tuberosity Cp.
  • the lower end portion of the Achilles tendon is attached to the calcaneal tuberosity Cp , and a portion of the Achilles tendon that is above the calcaneal tuberosity Cp is substantially displaced during motion whereas the calcaneal tuberosity Cp itself does not substantially change during motion. Therefore, it is expected that for the back side, the slippage off the upper will decrease by inserting a thick sponge in the area of the calcaneal tuberosity Cp at generally the same level as on the lateral side Lat of the foot.
  • the amount of slippage was particularly small when a 10 mm or 15 mm sponge plate Sp was installed.
  • An upper 1 of the present invention includes an inner skin 11 placed on a wear's skin side (a side to face a wear's skin), and an outer skin 12 placed on an opposite side from the inner skin 11 , wherein a sponge member 3 is housed between the inner skin 11 and the outer skin 12 in the heel portion 10 ; the sponge member 3 includes a medial side portion 34 covering a medial side of a calcaneal bone Ca , and a lateral side portion covering a lateral side of the calcaneal bone Ca ; and in a developed view where the sponge member 3 is unfolded into a planar shape (plane figure), a level of a lateral first centroid O10 of a portion corresponding to the lateral side portion is set to be higher than a level of a medial first centroid O11 of a portion corresponding to the medial side portion 34.
  • the level of the lateral first centroid O10 is higher than the level of the medial first centroid O11. Therefore, the sponge member 3 is placed in an area where the shape of the foot is hollowed and does not change substantially, i.e., in the lower portion directly below the medial ankle of the foot and in an area immediately below the lateral ankle of the foot, and the fit will therefore improve.
  • a sponge member refers to a member of a foamed synthetic resin or a foamed rubber that easily deforms under a load of an external force and that generally restores its original shape upon removal of the external force.
  • a sponge member may be a member that is cut off or cut out from a sponge plate of a predetermined thickness, or may be obtained by subjecting such a member to secondary molding in a mold.
  • a sponge member may be a member individually foamed and molded in a mold.
  • centroid means the center of a shape.
  • the medial side portion 34 covers at least a portion of a lower edge Ce of the calcaneal bone Ca directly below a talus Ta
  • the lateral side portion 35 covers an area of the calcaneal bone Ca directly above a point O , wherein the point O bisects a distance between a lowermost end point Ae of a lateral ankle A0 and the lower edge Ce of the calcaneal bone Ca.
  • the medial side portion 34 of the sponge member 3 fills the narrowed portion directly below the talus Ta.
  • the lateral side portion 35 of the sponge member 3 fills the narrowed portion directly and immediately below the lateral ankle A0. Therefore, narrowed portions on the medial side and the lateral side of the heel will be filled, and the upper 1 will better fit the heel.
  • the sponge member 3 includes a thin portion 3a having a small thickness, and a thick portion 3b thicker than the thin portion 3a , and wherein with the sponge member 3 unfolded, a perimeter of the thick portion 3b is surrounded by the thin portion 3a.
  • the thick portion 3b protrudes with respect to the thin portion 3a , and the triangular narrowed portions on the medial side and the lateral side of the heel will likely be filled by the protruding area.
  • a level of a lateral second centroid O20 of a portion of the thick portion 3b corresponding to the lateral side portion is set to be higher than a level of a medial second centroid O21 of a portion of the thick portion 3b corresponding to the medial side portion 34.
  • the level of the lateral second centroid O20 of the thick portion 3b is higher than the medial second centroid O21 of the thick portion 3b. Therefore, the thick portion 3b is placed in an area where the shape of the foot is hollowed or narrowed and does not change substantially, i.e., in the lower portion directly below the medial ankle of the foot and in an area directly (nearly immediately) below the lateral ankle of the foot, and the fitting property will therefore further improve.
  • a lower edge line 3bL of the thick portion 3b extends, while being upwardly slanted, from a medial side of the heel portion 10 to a lateral side thereof via a back side thereof.
  • the thick portion 3b will likely fill the gap in the lower portion of the heel portion 10 on the medial side of the heel portion 10 , fill the gap behind the calcaneal tuberosity Cp on the back side of the heel portion 10 , and fill the gap in the upper portion of the heel portion 10 on the lateral side of the heel portion 10.
  • a lower edge line 3L of the sponge member 3 extends, while being upwardly slanted, from a medial side of the heel portion 10 to a lateral side thereof via a back side thereof.
  • the sponge member 3 will likely fill the gap in the lower portion of the heel portion 10 on the medial side of the heel portion 10 , fill the gap behind the calcaneal tuberosity Cp of the heel portion 10 on the back side of the heel portion 10 , and fill the gap in the upper portion of the heel portion 10 on the lateral side of the heel portion 10.
  • the sponge member 3 includes:
  • the manufacturing cost will be significantly lower as compared with a case where the sponge member 3 is molded in a mold in a secondary molding process, or the like. Moreover, the sponge member 3 will not have locally dense portions.
  • the second sponge plate 32 is formed by a material having a lower resilience than the first sponge plate 31.
  • the low-resilience second sponge plate 32 placed on the foot skin side maintains, with a small pressure, the shape in conformity with the surface of the foot, it is possible to achieve a desirable foot conformity.
  • the shape of the heel substantially changes instantaneously, the high-resilience first sponge plate 31 will likely follow such changes. Therefore, the fitting property of the upper will further improve.
  • low resilience means that the speed at which the original shape is restored upon removal of a load of an external force is low. Therefore, when a load of an external force is applied to both of the sponge plates 31 and 32 , the high-resilience first sponge plate 31 will deform quickly, and the deformation of the low-resilience second sponge plate 32 will lag behind. Upon removal of the load of the external force off both of the sponge plates 31 and 32 , the first sponge plate 31 will quickly restore its original shape, and the restoration of the second sponge plate 32 will lag behind the first sponge plate 31.
  • the second sponge plate 32 is formed by a material having a lower hardness than the first sponge plate 31.
  • the low-hardness second sponge plate 32 placed on the foot skin side will softly contact the skin surface of the heel. Therefore, the wearer will unlikely feel compressed.
  • the second sponge plate 32 is formed by a material having a lower resilience and a lower hardness than the first sponge plate 31.
  • the material of the first sponge plate 31 having a high hardness and a high resilience may be, for example, an urethane foam, a silicone foam, or the like, whereas a material having a low hardness and a low resilience may be, for example, an urethane foam, a silicone foam, or the like.
  • the material of the high-resilience first sponge plate 31 has a lower resilience than the sponge material used in an ordinary midsole or a sock liner (sock lining), it has a relatively higher resilience than the material of the low-resilience second sponge plate 32.
  • the hardness of the first sponge plate 31 is preferably 40 to 90 degrees, more preferably 55 to 90 degrees, particularly preferably 70 to 90 degrees, and most preferably 75 to 85 degrees, in terms of the F hardness.
  • the hardness of the second sponge plate 32 is preferably 10 to 80 degrees, more preferably 10 to 50 degrees, particularly preferably 10 to 30 degrees, and most preferably 15 to 25 degrees, in terms of the F hardness.
  • the above F hardness is a value obtained through measurement using the Asker rubber hardness meter F-type (from Kobunshi Keiki Co., Ltd.). Note that the hardness of the first sponge plate 31 and the hardness of the second sponge plate 32 will be substantially zero degree if measured by using a JIS C hardness meter.
  • the sponge member 3 further includes a back portion 30 covering a calcaneal tuberosity Cp from directly behind along a virtual line CL dividing the sponge member 3 into the medial side portion 34 and the lateral side portion 35 , and the sponge member 3 defines a narrowed portion 36 which is narrowed downwardly along the virtual line CL and which does not cover an area above the calcaneal tuberosity Cp.
  • the gap which likely occurs between the calcaneal tuberosity Cp and an area of the upper behind the calcaneal tuberosity Cp , will be filled by the back portion 30 , thereby improving the fitting property.
  • the narrowed portion 36 will accommodate substantial displacement or deformation of the Achilles tendon, and therefore the movement of the Achilles tendon will unlikely be hindered.
  • FIGS. 4 to 5D show Embodiment 1.
  • the upper 1 includes the inner skin 11 placed on the wear's skin side, and the outer skin 12 placed on the opposite side from the inner skin 11.
  • the sponge member 3 is housed between the inner skin 11 and the outer skin 12 in the heel portion 10.
  • FIG. 4 merely shows the conceptual placement of the sponge member 3.
  • Reference numeral 6 denotes an insole.
  • the inner skin 11 may be a mesh material, or the like, as well as a woven material or a knit material having desirable stretchability and air-permeability.
  • the outer skin 12 may be a mesh material, or the like, as well as a plate or tape material made of a synthetic leather or a non-foamed synthetic resin having a desirable shape retention.
  • each of the inner skin 11 and the outer skin 12 may include a single layer or multiple layers.
