Definitions

  • This invention relates to a slip-resistant sole for footwear.
  • a problem with which this invention is concerned is the provision of a slip-resistant sole which exhibits good slip-resistance omni-directionally or in the major directions in which slip is likely to occur both in the dry and in an environment such as a kitchen where spillage of both oil and water can occur.
  • a slip-resistant sole which exhibits good slip-resistance omni-directionally or in the major directions in which slip is likely to occur both in the dry and in an environment such as a kitchen where spillage of both oil and water can occur.
  • footwear that exhibits good slip-resistance on smooth tiled surfaces contaminated with cooking oils or fats.
  • each cleat may have a pair of non-linear edges defined by grooves separating adjacent cleats, said grooves having a general direction transversely of the sole and having a wavy shape.
  • the sole will be formed with a set of the grooves at equal spacings.
  • the grooves have regularity, with a pitch or wavelength related to the dimension of the cleats so that adjacent cleats have convex and concave edges alternately. With this cleat edge profile there is a maximised chance that the cleats will have leading edges facing in a direction of possible slip.
  • the leading edges act as squeegees to remove fluid films and for that purpose are made as sharp as possible bearing in mind the materials and moulding techniques employed e.g. high-pressure moulding.
  • the grooves may run obliquely across the sole with the medial end of each groove in advance of the lateral end. Preferably the grooves are directed at an angle of about 65° to the toe to heel direction.
  • each cleat has a second pair of non-linear edges defined by second grooves separating adjacent cleats and directed so as to intersect the first grooves, said second grooves also having a wavy shape.
  • the angle of intersection is conveniently close to a right angle but need not be precisely 90°.
  • the second set of grooves will normally also be formed in the sole at equal spacings, with the spacing of the grooves of the second set being at least twice the spacing of the grooves of the first set.
  • the aspect ratio of the cleats undisturbed by a shoe edge is thus 2:1 or more.
  • the second grooves may have generally the same pitch or wavelength as the grooves of the first set, and may run obliquely across the sole in a direction opposite to the grooves of the first set, with the lateral end of each second groove in advance of the medial end.
  • the grooves of the second set may be directed at an angle of about 23° to the toe to heel direction.
  • the dimensions of the cleats should be sufficiently large to avoid the risk of break-away during service of the sole but there must also be sufficient grooves or channels to provide fluid drainage.
  • cleats not adjacent the edges of the sole each have a major dimension of about 12 mm and a minor dimension of about 6 mm.
  • the grooves are advantageously dimensioned for ease of cleaning and ease of the release of trapped articles on flexion. They are also dimensioned to maximise ground contact, to maximise break-up of fluid films on the ground under the sole, and to ensure that oils and water are likely to be expelled to the edges of the cleats and drained effectively. Thus they may be of width about 2 mm at the exposed face of the sole. The depth will normally be selected on the basis of intended service life of the sole, but is typically about 4 mm.
  • the sole has a lower face for continuous ground contact from toe to heel, and the pattern of cleats also extends continuously from the toe end to the heel end thereof.
  • Optimum slip resistance in an environment liable to oil and water contamination is provided by appropriate selection of sole cleat or stud pattern combined with appropriate selection of material and hardness.
  • the sole is preferably moulded in rubber, especially a nitrile or other oil-resistant rubber. It has been found that a sole moulded in rubber retains slip-­resistance better than a moulded polyurethane sole using the materials presently available.
  • the material has to combine the properties of adequate oil-resistance, slip-resistance and abrasion resistance and for this purpose it should be of Shore hardness about 60-70, preferably about 65.
  • a lower rubber layer may be united at a blind face to an upper layer of blown polyurethane or other expanded plastics material.
  • the upper layer then preferably has a tranversely cupped forepart to support the weight of the metatarsus with a minimum of disturbance of the flatness of the lower face of the sole.
  • the invention is not, however, limited to use in purpose made slip- resistant footwear, and could take the form of rubber replacement for use in the repair of shoes, or it could be used in boots, shoes and slippers for wear by the general public.
  • the invention also provides a slip-resistant boot or shoe having a sole as aforesaid.
  • the invention resides in the use of a slip-resistant sole as aforesaid in a place having a smooth impermeable floor liable to contamination with oil or grease, for example a ceramic tiled floor of a catering establishment.
  • a moulded composite sole for safety shoes for use in kitchen having a ceramic tiled floor and in which much fried food is cooked such as a "fast food” establishement has a lower layer 10 of nitrile rubber of 65 Shore hardness and an upper layer 12 of blown polyurethane.
  • the polyurethane layer 12 cushions the foot and spreads the load onto the underlying rubber layer 10.
  • the lower face of the rubber layer 10 is formed with a pattern of equi-spaced first sinuous grooves 14 and a pattern of second sinuous gooves 16 intersecting the first grooves to define a pattern of studs or cleats having four non-linear edges.
  • the wavelength of the undulations of grooves 14 (which can resemble sine waves but need not have strict regularity) is related to the pitch or spacing of the grooves 16 so that cleats 18 are defined in which corresponding edges 22, 24 of many adjacent cleats are alternately convex and concave as shown.
  • the regularity of the undulations and the relationship between them may however be only approximate.
  • Both the grooves 14 and the grooves 16 are directed obliquely to the heel-toe direction and they intersect at approximately a right angle.
  • the grooves 14 are more significant for defining slip-­resistance leading edges, whereas the grooves 16 which are directed closer to the toe to heel direction are more important from the standpoint of fluid drainage from the contact area.
  • sole is intended to make continuous flat ground contact from the ball of the foot to the heel, and that the pattern of cleats is continuous from toe to heel.
  • the heel is chamfered at an angle of about 15° as at 26, the undulating cleat-defining grooves 14, 16 extending into the heel region as shown.
  • the grooves 14 extend through a major portion of the thickness of the rubber layer 10, the layer 10 locally being 6 mm thick and the grooves 14 being 4 mm deep.
  • the profile of gooves 14 is inwardly tapering at an angle of 3° for ease of release during moulding and also for ease of cleaning.
  • the polyurethane layer 12 at the toe and metatarsal region of the sole is of thickness about 3mm, but thickness increases to about 20 mm in the heel region to cushion the force of heel contact during walking.
