[0001] The invention relates to protective toe caps for use in footwear for protecting the
toes of the wearer against injury.
[0002] 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.
[0003] An object of the present invention is to provide an improved toe cap moulded from
plastics material.
[0004] According to the present invention there is provided a protective toe cap for use
in footwear for protecting the toes of the wearer against injury, comprising a curved
member adapted to lie over the toes of the wearer and extend down to a lower edge
at the sole portion of the footwear around the sides and the front of the toe area
of the foot, the member being moulded from fibre reinforced plastics material and
having a thickened area around the lower front part thereof and the forward part of
the sides thereof, the thickened portion tapering in an upward and rearward direction
and merging smoothly with the main thinner part of the toe cap.
[0005] Preferably the rear edge of the toe cap tapers smoothly from the main part of the
toe cap to facilitate merging of the rear edge of the toe cap with the upper of the
article of footwear.
[0006] Preferably the lower edge is reinforced by an inwardly directed integrally moulded
flange.
[0007] An embodiment of the invention will now be described by way of example only with
reference to the accompanying drawing in which:
Figure 1 is a diagrammatic side elevation of a toe cap according to the invention
Figure 2 is a corresponding plan view of the toe cap.
Figure 3 is a longitudinal cross section of the toe cap on line III-III of Figure
2; and
Figure 4 is a transverse section on line IV-IV of Figure 2.
[0008] 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.
[0009] 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.
[0010] 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.
[0011] It has been found that this gradual merging and tapering of the thickness around
the front end of the toe cap helps to strengthen the whole of the toe cap and thereby
allows an acceptably thin main portion 12 to be used. It is essential to avoid excessive
thickness in the main area 11 because this would adversely affect the appearance of
the boot or shoe which may well be a fashion product as well as a safety product.
The limited thickening and gradual taper of the front part of the footwear merely
adds a requirement for a small increase in length and does not detract significantly
from the appearance of the footwear.
[0012] To provide further strengthening, the lower edge of the toe cap is provided with
an inwardly directed integrally moulded flange 15.
[0013] 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.
1. A protective toe cap for use in footwear for protecting the toes of the wearer
against injury comprising a curved member adapted to lie over the toes of the wearer
and extend down to a lower edge at the sole portion of the footwear around the sides
and the front of the toe area of the foot, the member being moulded from fibre reinforced
plastics material and having a thickened area around the lower front part thereof
and the forward part of the sides thereof, the thickened portion tapering in an upward
and rearward direction and merging smoothly with the main thinner part of the toe
cap.
2. A protective toe cap as claimed in Claim 1 wherein the rear edge of the upper part
of the toe cap tapers smoothly from the main part of the toe cap to facilitate merging
of the rear edge of the toe cap with the upper of the article of footwear.
3. A protective toe cap as claimed in Claim 1 or Claim 2 wherein the lower edge is
reinforced by an inwardly directed integrally moulded flange.
