  • Patent number: 6438869
    Abstract: A construction for a shoe, particularly an athletic shoe such as a running shoe, includes a sole that conforms to the natural shape of the foot, particularly the sides, and that has a constant thickness in frontal plane cross sections. The thickness of the shoe sole side contour equals and therefore varies exactly as the thickness of the load-bearing sole portion varies due to heel lift, for example. Thus, the outer contour of the edge portion of the sole has at least a portion which lies along a theoretically ideal stability plane for providing natural stability and efficient motion of the shoe and foot particularly in an inverted and everted mode.

  • Patent number: 6415531
    Abstract: A plane-shaped lighting device has a light-directing plate and a light source that is placed in contact with or in the proximity of the light-incident surface of the light-directing plate, and the light source is constituted of a plurality of LED lamps each of which has an LED chip for emitting light and a semispherical lens for directing the light from the LED chip into the light-directing plate. Here, the distance from the LED chip to the top of the semispherical lens is set to be 1.8 times as long as the radius of curvature of the semispherical lens. This arrangement allows the light emitted from the LED chip to be efficiently incident on the light-incident surface of the light-directing plate, thereby improving the light-incidence efficiency to the light-directing plate. Further, the application of this plane-shaped lighting device to display devices makes it possible to improve the efficiency of light utilization, and consequently to provide thinner display devices with high visibility.

    Abstract: A midsole assembly for an athletic shoe includes a midsole formed of soft elastic material and a corrugated sheet disposed in a heel portion to a forefoot portion of the midsole. The upper midsole has a different hardness than the lower midsole. When the upper midsole has a lower hardness than the lower midsole, foot contact feeling and cushioning properties can be improved. On the other hand, when the lower midsole has a lower hardness than the upper midsole, shock load on landing is relieved and the cushioning properties can be improved. Moreover, in this case, when the load from the sole of a foot is applied to the upper midsole having a relatively high hardness, the corrugated sheet functions in such a way that the lateral deformation of the upper midsole can be prevented and running stability can be secured.

  • Patent number: 6311414
    Abstract: An athletic shoe midsole assembly includes a midsole formed of soft elastic material and a corrugated sheet disposed in the heel portion of the midsole. The corrugated sheet has a pocket structure at edge areas of the sheet, for example the medial side edge, formed by two layers spaced apart from each other with a respective void pocket formed therebetween. Since the compressive hardness of the midsole is higher on the medial side including the pocket structure, transverse deformation of the shoe on landing can be prevented and over-pronation can be restrained on this medial side and the loss of athletic power can be decreased. On the other hand, flexibility of the midsole is maintained on the lateral side without a pocket structure and thus cushioning properties can be secured on this lateral side.

  • Patent number: 6163982
    Abstract: In its simplest conceptual form, the applicant's invention is the structure of a conventional shoe sole that has been modified by having its sides bent up so that their inner surface conforms to a shape nearly identical but slightly smaller than the shape of the outer surface of the sides of the foot sole of the wearer (instead of the shoe sole sides conforming to the ground by paralleling it, as is conventional). The shoe sole sides are sufficiently flexible to bend out easily when the shoes are put on the wearer's feet and therefore the shoe soles gently hold the sides of the wearer's foot sole when on, providing the equivalent of custom fit in a mass-produced shoe sole. This invention can be applied to shoe sole structures based on a theoretically ideal stability plane as a basic concept, especially including structures exceeding that plane.

  • Patent number: 6154983
    Abstract: A shoe and an improved method of shoe construction comprising an upper, an insole, a midsole, and an outsole, that are coupled together to form a housing for receiving a foot, and wherein the midsole is enveloped by the bottom ends of the upper, the insole, and the outsole to provide a more secure and stable fit of the shoe to the foot. The shoe is constructed to have the midsole of the shoe enveloped by the combination of the upper, insole, and outsole. This method of shoe construction results in a shoe having an improved fit because the midsole is pulled from the top and the bottom to provide improved fit, support, stability, and cushioning characteristics.

  • Patent number: 6138385
    Abstract: The aim of the invention is to design a sole (1), and a shoe with such a sole (1), so that the length of the sole (1) or of the upper attached to it can be easily adjusted, using adjustment means (11), to meet the needs of the wearer of the shoe. This is achieved by virtue of the act that a front thrust block (7) is fitted at the rear (5) of the front sole (2) and a rear thrust block (8) at the front (6) of the rear sole (3). The shoe is fitted with at least one adjustment means (11) which forms a force-locking connection with the two thrust blocks (7, 8), the jointed section (4) thus being adjustable by the adjustment means (11) to various lengths.

  • Patent number: 6119373
    Abstract: An athletic shoe including a upper, a support member or "chassis" attached to the underside of the upper, and sole elements attached to the bottom of the support member. The support member provides support for the foot, and thereby permits use of spaced apart sole elements rather than a full midsole and a full outsole. In addition, the support member can be tailored to provide the optimum stiffness for a particular activity or user.

  • Patent number: 6115941
    Abstract: A construction for a shoe, particularly an athletic shoe such as a running shoe, includes a sole that conforms to the natural shape of the foot, particularly the sides, and that has a constant thickness in frontal plane cross sections. The thickness of the shoe sole side contour equals and therefore varies exactly as the thickness of the load-bearing sole portion varies due to heel lift, for example. Thus, the outer contour of the edge portion of the sole has at least a portion which lies along a theoretically ideal stability plane for providing natural stability and efficient motion of the shoe and foot particularly in an inverted and everted mode.

  • Patent number: 6101743
    Abstract: A thin orthotic insert having a rigid rearfoot plate and a flexible forefoot cushion which are joined together without requiring a separate top cover. A connection is formed by a slot at the forward edge of the plate which receives and holds the rearward edge of the cushion layer. The rearfoot plate may be formed as a laminated structure, with forward edges of the upper and lower laminate layers being separated to form the wall portions above and below the slot. To form the slot, a spacer is inserted between the edges of the layers and then withdrawn after molding/curing. Because the need for a top cushion is eliminated, very low thicknesses can be achieved, on the order of 1.5 mm. The device is particularly advantageous for use in women's high-heeled shoes, where interior volume is extremely limited.

  • Patent number: 6079126
    Abstract: A shoe construction is provided which conforms to the natural design and movement of a human foot. The shoe includes a bottom and an upper. The bottom is defined by a heel, an arch portion, a hinge portion and a forward portion. The upper is attached to a top surface of the bottom and includes a thinned section overlying the hinge portion. During use, the hinge portion and thinned section act in concert to facilitate a natural walking and/or running motion. In this regard, the hinge portion encourages pivoting of the foot at the ball. Similarly, the thinned section is configured to buckle during a pivoting motion of the foot. Thus, the thinned section provides minimal resistance as the foot maneuvers through a running motion.

  • Patent number: 6076284
    Abstract: A shoe, e.g. for dance or athletics, having a split sole, with a front portion at the front of the foot, a rear portion beneath the rear of the foot and no sole beneath the mid-section of the shoe upper at the mid-section of the foot, beneath the arch. To help support the foot and prevent sag of the mid-section of the shoe upper, a band of flexible, but non-stretchable, fabric is stitched inside the shoe upper to extend from the bottom of the shoe upper, up the sides of the shoe upper, to the top of the shoe upper. The stitched in material supports the mid-section of the bottom of the shoe upper against sagging, while permitting the foot to be flexed. If the shoe has a split top side of the upper and is closed or laced, the closing of the top of the shoe upper pulls up on the band.
