Definitions

  • the slip resistant shoe sole of Patent Document 1 is capable of walking stably even on a floor surface or the like in a slippery state (paragraph 0021 of the same document).
  • the slip-resistant shoe sole of Patent Document 1 has become a hot topic because it is difficult to slip even in factories and kitchens where the floor surface is slippery.

  • a plurality of anti-slip protrusions provided downward from substantially the entire area of the lower surface of the front portion and the rear portion of the shoe sole body, with a gap between each other,
  • the dynamic friction coefficient of the region where the anti-slip protrusion is provided on the lower surface side of the shoe sole (hereinafter referred to as “non-slip protrusion forming region”) is 0.3 or more,
  • the sticking amount of the sticky substance in the non-slip protrusion forming region is 1.5 g or less,
  • dynamic friction coefficient means a dynamic friction coefficient measured by “9.7 slip resistance test” (lubricating liquid: glycerin aqueous solution, test floor: stainless steel plate) in “JIS T 8101: safety shoes”. Say.
  • the “viscous material peeling bending frequency” means the bending frequency N obtained by the following procedures B1 to B8.
  • Procedure B1 A shoe sole sample (30 cm (vertical) ⁇ 15 cm (horizontal)) to be measured is prepared and placed on a horizontal plane with its ground contact surface facing upward.
  • Procedure B2 A clay having a density of 0.345 ⁇ 0.01 [g / cm 3 ], a shrinkage ratio under pressure of 80 ⁇ 2 [%], and a maximum peel load of 5.6 ⁇ 0.2 [N] is prepared.
  • Procedure B3 As shown in FIG.
  • the “shrinkage ratio under pressure” (refer to the above-mentioned procedure B2) of clay refers to the shrinkage ratio R obtained by the following procedures C1 to C5.
  • Procedure C1 The clay to be measured is formed into a cylindrical shape having a diameter of 20 mm and a height of 25 mm (hereinafter referred to as “initial height H 0 ”).
  • Procedure C2 The clay obtained in the procedure C1 is erected on the horizontal plane in a state where the height direction is substantially perpendicular to the horizontal plane.
  • Procedure C3 A load of 1.1 kg is applied for 10 seconds downward from the upper side to the upper end surface of the clay erected in the procedure C2.
  • Procedure C4 The height of the clay after the completion of the procedure C3 (hereinafter referred to as “post-pressing height H 1 ”) is measured.
  • Procedure D4 As shown in FIG. 9 (d), the pull gauge 120 is attached to the hook 101 of the pressing tool 100 that has finished the procedure D 3 and pulled upward in the vertical direction, and the clay 50 is peeled from the stainless steel plate 110.
  • Procedure D5 The load (maximum load F) of the pull gauge when the clay 50 is peeled from the stainless steel plate 110 in the procedure D4 is read, and this maximum load F is set as the maximum peeling load [N] of the clay.
  • the anti-slip projections are in other forms such as a cylinder or a quadrangular prism, or the anti-slip projections are placed in other positions, such as where the anti-slip projections are placed at the positions of the lattice points of the square lattice. This is because it has been confirmed that the dynamic friction coefficient, the sticking amount of the viscous substance, and the number of viscous substance peeling and bending can be increased in a balanced manner.
  • the number density of the anti-slip protrusions is preferably 2 pieces / cm 2 or less.
  • the number density of the anti-slip protrusions is more preferably 1.5 pieces / cm 2 or less, and further preferably 1 piece / cm 2 or less.
  • the shoe sole 10 includes a shoe sole body 11 and a plurality of anti-slip protrusions 12 as shown in FIGS. 1 and 2.
  • the shoe sole 10 it is possible to further reduce the number of viscous substance peeling and bending in the anti-slip projection forming region to 10 times or less (Examples 1 and 2 described later).
  • the lower limit of the number of times the viscous material is peeled and bent in the anti-slip protrusion forming region is not particularly limited, but it is usually assumed that it is difficult to make it less than once.
  • / S 1 is the portion of the unit grid UL on the lower end surface of the anti-slip protrusion 12 with respect to the area of the unit grid UL (the portion indicated by hatching in the figure). It can be determined by calculating the area ratio.
  • the gap ⁇ is parallel to the horizontal direction of the shoe sole 10 (thickness in the figure). makes with dashed L 0 ° direction), the direction (direction of the thick broken line L 60 ° in the drawing) constituting a 60 ° with respect to the lateral direction of the sole 10, a 120 ° relative to the horizontal direction of the sole 10 direction to form a total of three directions of (thick broken line L 120 ° direction in the figure), adjacent slip butt This is because it is possible to more easily flake off in walking such things jammed in 12 of the gap beta.
  • triangular prism-shaped non-slip protrusions 12 are respectively arranged at positions that form hexagonal lattice points.
  • the one anti-slip protrusion 12 and the other anti-slip protrusion adjacent to the one anti-slip protrusion 12 are such that the triangles formed by the lower end surfaces thereof are opposite to each other.
  • the anti-slip protrusions 12 are arranged to a certain degree to increase the slip resistance of the shoe sole 10 while the gap ⁇ along the thick broken lines L 0 ° , L 60 ° , and L 120 ° in FIG.
  • a wide width (see width W 1 in FIG. 2) can be secured to make it difficult for objects to clog in the gap ⁇ of the anti-slip protrusion 12, and it is also possible to make objects clogged in the gap ⁇ easily peel off. ing.
  • the samples of Examples 1 to 3 showed an excellent value of 0.45 or more in terms of the value of the dynamic friction coefficient, although it did not reach the sample of Comparative Example 1.
  • the value of the dynamic friction coefficient is 0.49 or more. From this, it was found that the samples of Examples 1 to 3 could exhibit good slip resistance even though the slip resistance was not as good as that of the sample of Comparative Example 1.
  • the value of the number of times of viscous material peeling and bending is 20 times or less, which is half or less than that of the sample of Comparative Example 1.
  • the samples of Examples 1 and 2 have a value of the number of viscous substance peeling and bending of 16 times, which is 1/3 or less compared to the sample of Comparative Example 1. From this, it was found that the samples of Examples 1 to 3 were much easier to peel off the viscous material once adhered compared to the sample of Comparative Example 1.
