Definitions

  • This invention relates to toe caps and in particular to safety and protective top caps.
  • safety top caps have remained substantially unchanged since at least the Second World War and they comprise a unitary steel body, which is generally U shaped in both vertical and horizontal section with the outer wall being slightly splayed. The trailing edge of this cap is cut straight across so that it is substantially parallel to a transverse axis extending through the leading point of the cap.
  • the toe cap generally overlies a substantial portion of the user's big toe and lesser portions of the two adjacent toes. The third toe and the little toe are usually exposed.
  • the invention consists in a safety or protective toe cap having a leading point lying on a transverse toe axis, a trailing edge through which a trailing axis passes along a line parallel to the toe axis and through the point on the trailing edge which is nearest the toe axis characterised in that a substantial portion of the trailing edge extends rearward of trailing axis and is inclined thereto.
  • the angle of inclination between the trailing edge and the trailing axis may initially be in the range of 4° to 10° and may subsequently increase. Indeed the angle of inclination may progressively increase as the trailing edge extends from the point or, alternatively, the increase in angle of inclination may take place adjacent the third toe position.
  • the trailing edge may extend extensively parallel to the line of flexure of an intended user's foot.
  • the outer wall of the cap may extend to a point adjacent the little toe position of the intended user's foot and it is preferred that both the inner and the outer walls extend beyond the point.
  • the trailing edge may be raked rearwardly as it extends along the wall portions of the toe caps.
  • the invention consists in a toe cap having a trailing edge contoured to correspond substantially with the natural line of flexure of a human foot.
  • the invention includes a toe cap having an outer wall portion which extends rearwardly of its inner wall portion.
  • the toe cap may be made of steel.
  • the invention also includes an article of footwear incorporating a toe cap as defined above.
  • outside refers to that part of a toe cap or shoe which is intended to extend on the side of the user's foot which bears the little toe and "inside” correspondingly refers to that side which equates to the user's foot that bears the big toe or hallux.
  • FIG. 1b A prior art toe cap 10 is shown in Figure 1b and it will be seen that its foremost point 11 is abutted against a transverse axis 12.
  • the axis 12 will be denominated the "transverse toe axis”.
  • the trailing edge 13 of the toe cap 10 extends substantially parallel to the transverse toe axis 12 and indeed a trailing axis 14 can be defined which extends parallel to the transverse toe axis through the point 15 on the trailing edge which is nearest the toe axis.
  • the toe caps illustrated are of the size which would be used normally for footwear in the range 8 - 91 ⁇ 2, and for a size 9 wearer, the toe cap 10 would extend substantially over the user's big toe and partially over the user's next two toes, leaving the remaining two toes almost completely exposed, particularly to side impacts.
  • the Applicant's toe cap 10a has a trailing edge 13a which is inclined rearwardly from the trailing edge axis 14 from the nearest point 15a towards the outside wall portion 18b. It will be noted that the angle of inclination ⁇ , in this particular embodiment, becomes progressively greater so that the trailing edge 15a in fact substantially follows the line of the flexure or flex angle 16 of the user's foot.
  • This change in design arises from the Applicant's appreciation that the nature of the crease formed in the footwear upper can be to an extent determined by the shape of the trailing edge of the toe cap.
  • the result is that the crease 17a, which is formed by the Applicant's toe cap, substantially follows the flex angle 16 of the foot and the crease no longer digs into the user's foot in the manner that has existed for at least the last 50 years.
  • the outer wall portion 18a is also raked rearwardly so that it can provide significant side protection, without moving the location of the crease 17a undesirably far back relative to the user's foot.
  • a similar, but less substantial raking of the inner side wall 19a is also achieved.
  • the design also provides more substantial coverage from above of the user's toes and typically the fourth toe is well protected with some protection, particularly from side impact being provided to the user's little toe.
  • the toe caps are made of steel, but in fact the design may also work well as a plastics safety or protective toe cap, because, as can be seen in Figure 2, it allows a higher arch to be provided and this can be significant in plastics toe caps where a degree of deflection on impact is more likely to occur.
  • top cap of this invention is principally an internal protective toecap, because it is in this situation that the problem of creasing particularly arises.
  • External toecaps are generally used to protect the toecaps of the boots rather than to protect the user's toes.
  • the trailing edge of the applicant's toecap preferably extends substantially parallel to the line of flexure of an intended user's foot.
  • the cap should be asymmetric when viewed from above and the point on the trailing edge which is nearest the toe access needs to be offset from the leading point.
