Definitions

  • the invention relates to slip-resistant shoe soles.
  • Slip resistance can be improved by special tread patterns in the bottom surface of the outsole, and by siping the bottom of the outsole (i.e., incising parallel wavy cuts).
  • the invention features a slip-resistant shoe sole comprising an outsole layer having a bottom surface defining a region of contact between the sole and the ground, the outsole layer bearing a plurality of channels opening onto the bottom surface to define a pattern of elongated gaps across the contact region, the ratio of the area of the gaps to the surface area of the contact region and the configuration of the gaps being arranged to effectively cause liquid between the contact region and the ground to be conducted away, while enhancing the slip resistance produced by the contact region engaging the ground.
  • the outsole layer bears a plurality of siping slits (preferably only in the toe area); the ratio of the area of the gaps to the surface area of the contact region is no less than 10% and no more than 40%; each gap is no less than 1/16" wide; each gap is bounded by wiping edges where walls of the channel meet the bottom surface, the wiping edges being contoured to include sections perpendicular to a longitudinal axis of the sole and sections at oblique angles to the longitudinal axis, whereby liquid between the contact region and the ground is effectively forced into the channels and conducted to the perimeter of the sole, enhancing the slip resistance produced by the contact region engaging the ground at an angle of attack either along or oblique to the longitudinal axis; the portions of the contact region between the elongated gaps include friction pads no shorter than 3/16" (preferably 1/4") in their shortest dimension and no longer than 0.60" in their longest dimension; each channel has walls which meet the contact region at an angle greater than 105° (preferably 1100); the friction pads include
  • the grooves conduct liquid toward the shoe perimeter (i.e., away from weight-bearing and contact surfaces), and the siping aids by wiping the contact surface, thus improving the friction between the contact region and the ground and reducing slipping and hydroplaning.
  • the wiping edges enhance the wiping of liquid into the grooves.
  • the contour of the wiping edges assures that wiping will occur even when the shoe strikes the ground in directions oblique to the longitudinal axis of the sole.
  • the void-to-contact ratio of gap area to contact area enhances both the conducting of liquid away from the shoe and the frictional slip-resistance of the contact region against the ground.
  • the size of the channels assures adequate space for the conducting of liquid, and the angle of the channel walls minimizes the accumulation of small objects in the channels.
  • the large angle between the channel walls and the contact region aids in ejecting foreign objects.
  • the sizes of the friction pads aid in their flexibility, and enable the friction pads to move independently of each other to provide good contact with the ground even during unusual foot movements or uneven weight distribution, e.g., movements on boat decks.
  • the friction pads and bars are large enough to reduce the likelihood of damage to them.
  • the sole effectively grinds particles, e.g., food, lying on the ground, thus reducing the likelihood of the user slipping.
  • the shock foam inserts reduce shock to the user's foot, and provide more uniformity of pressure distribution to the bottom of the outsole.
  • the flatness of the contact region improves the slip resistance.
  • the bottom surface of outsole 10 (men's size 10) has a tread pattern with sixteen transverse wavy grooves 12 on the toe and heel areas.
  • Grooves 12 are arranged in pairs 14, with the grooves of each pair connected by short straight grooves 16 each of which is oriented perpendicular to the two grooves of the pair and oblique to the longitudinal axis 18 of outsole 10.
  • Each groove pair 14 extends from one side to the other side of outsole 10 in a region outlined by Littleway stitching groove 20 which follows along the perimeter of outsole 10.
  • the axis 22 of each groove pair 14 is oriented at an 80° angle to axis 18.
  • each groove pair 14 is oriented perpendicular to axis 18.
  • each groove pair 14 has an extension 24 which passes beyond Littleway groove 20 to the very edge of outsole 10.
  • a row of friction pads 26 is defined by grooves 12, 16.
  • Each friction pad is no shorter than 3/16", and no longer than 0.60", preferably 1/4", long (i.e., in the direction of the longitudinal axis 18).
  • Between adjacent groove pairs 14 are friction bars 28, each of which is at least 3/8", and no longer than 0.60", preferably 1/2", long (in the direction of longitudinal axis 18).
  • Each friction bar 28 in the toe area bears a siping pattern 29 of three wavy cuts which undulate like grooves 12 (in Fig. 1, the siping is only shown on one of the frictions bars).
  • Each groove 12, by virtue of its wavy contour, has some sections which are perpendicular to axis 18 and other sections which are at various oblique angles to axis 18.
  • the heel portion of outsole 10 extends forward into the medial region to define an arch support 33.
  • grooves 12, 16, 20 are 0.080" deep v-shaped channels whose side walls 34 meet the bottom surface 36 of outsole 10 at an angle of at least 105° (preferably 110°). The corners where side walls 34 meet bottom surface 36 form wiping edges 35. Each groove 12, 16 thus forms a gap 38 of no less than 1/16" (preferably 0.080") in bottom surface 36.
  • Outsole 10 is molded of rubber (available under the name Sperry compound from Goodyear Tire & Rubber Company) having a durometer of 60-65 shore A. Outsole 10 is molded with the bottom surface 36 as flat as possible, minimizing doming or curving, to increase the contact area.
  • the ratio of gap area to contact area in the range between 10% and 40% maximizes both the conducting of liquid away from the shoe and the frictional slip-resistance of the contact region against the ground. Pebbles or other objects are not caught in the grooves because the grooves are relatively open.
  • the sizes of the friction pads promote their flexibility which enhances friction and enables them to flex independently, while reducing the likelihood of damage to them.
  • outsole 100 (for use by restaurant employees) has a tread pattern of grooves 102.
  • arc-shaped grooves 102 In the toe area, there are six concentric arc-shaped grooves 102 (for men's size 10) centered on a point 104 near the inside edge of the toe area. Adjacent arc-shaped grooves are separated by successively greater intervals at greater distances from point 104. Adjacent arc-shaped grooves 102 are connected by short straight grooves 106 which are aligned on radii centered at point 104. Littleway groove 108 follows along the perimeter of outsole 10. Extensions 110 of some of the arc-shaped grooves, and of some of the short straight grooves, extend beyond Littleway groove 108 to the edge of outsole 110.
  • arc-shaped grooves 112 which are generally perpendicular to the longitudinal axis 114-of outsole 100 and extend from side to side in the region outlined by Littleway groove 108. Two of the grooves 112 extend beyond Littleway groove 108 to the edge of outsole 100.
  • Grooves 102, 108 and extensions 110 are 0.090" deep v-shaped channels which form gaps of 0.110" in the bottom surface of outsole 100.
  • Each channel has a bottom radius of 0.04" to 0.06".
  • the side walls of each channel meet the bottom surface at an angle of 105°.
  • Outsole 100 is molded of rubber having a durometer of 52-56 Shore A scale.
  • the pattern of outsole 100 is particularly suitable in uses which require frequent rotational or swiveling motion around the ball area.
  • the undulations of each cut can be more frequent (200) than in Fig. 1.
  • the number of cuts on each friction bar can be more or less than three (200).
  • the undulations can be relatively frequent waves superimposed on less frequent waves (202, 204, 206) and the orientations of the superimposed more frequent waves can either be coordinated with the longitudinal axis (206) or with the less frequent waves on which they are superimposed (202, 204).
