Definitions

  • the invention relates to protective toe caps for use in footwear for protecting the toes of the wearer against injury.
  • Conventional protective footwear incorporates a pressed steel toe cap which is built in to an article of footwear in such a way that it is adapted to lie over the toes of the wearer and extend down to the sole portion of the article of footwear around the sides and the front of the toe area.
  • the toe cap then protects the toes of the wearer against being crushed when the front portion of the footwear is subjected to a heavy load or a hard blow.
  • Protective footwear incorporating steel toe caps can be cumbersome and heavy and this disadvantage is particularly relevant in the case of safety footwear for ladies. It has already been proposed in U.K.
  • Patent Specification 1,284,736 to form a toe cap for protective footwear from a plastics material but to achieve a useful degree of protection it was found necessary to provide the toe cap with a thick solid body of plastics material which was in use loaded purely in compression and so acted more as a spacer between the load and the ground than as a bridge protecting the toes.
  • This known toe cap of plastics material was also cumbersome because it required an increased length to the article of footwear and it was of limited value because it gave little or no protection against localised loads applied immediately behind the protective block.
  • a shaped sheet steel protective toe cap of varying thickness is described in US-A-. 2,151,554.
  • This toe cap comprises a top wall having a rear marginal portion tapering in thickness towards its edge and a skirt extending continuously along the opposite sides and front thereof and tapering in thickness towards its bottom and rear edges.
  • the toe cap is shaped from a flat blank which itself has its edges bevelled by hammering or rolling.
  • An object of the present invention is to provide an improved toe cap moulded from plastics material.
  • a protective toe cap for incorporation into industrial safety footwear comprising a curved member having a main area of substantially uniform thickness and adapted to lie over the toes of the wearer and extend down to a lower edge at the sole portion of the footwear characterised by the combination that:-
  • the lower edge is reinforced by an inwardly directed integrally moulded flange.
  • the drawing shows a toe cap with a generally curved shape for conforming to the toe part of a safety boot or safety shoe so that in use it would bridge the toes of the wearer and extend down to the sole of the shoe or boot in front of and to the side of the toes.
  • the toe cap is in the form of a single continuous curve in three dimensions.
  • the toe cap is moulded from a high strength fibre reinforced plastics material and in a typical example, the fibre is glass fibre.
  • the fibre is incorporated into the plastics material matrix in such a way as to form a composite which can be moulded without laying up individual layers of fibres.
  • the main area of the toe cap 11 is of substantially uniform thickness.
  • the front part 12 of the toe cap and the forward part 13 of the sides of the toe cap are of increased thickness compared with the main area 11 and this increased thickness tapers gradually and merges smoothly with the main part 11 of substantially uniform thickness.
  • the lower edge of the toe cap is provided with an inwardly directed integrally moulded flange 15.
  • a further feature which assists the appearance of the boot or shoe is that the rear edge portion 14 of the toe cap is tapered in thickness to facilitate merging of the toe cap with the remainder of the boot or shoe.
  • the decreased thickness in this area does not significantly affect the strength of the toe cap as a whole and allows a slight increase in the general thickness of the main area 11 without introducing an unsightly appearance.
