Definitions

  • the present invention relates to a toe protection cap.
  • the invention relates to a toe protection cap providing improved ventilation to the forefoot including the toes of the wearer without a necessity of taking a loss of the toe protection cap in mechanical resistance to impacts or pushes.
  • the invention also relates to footgear, e. g. safety shoes, protective shoes, occupation shoes, sports shoes, to name only a few without wanting to restrict the term, comprising such a toe protection cap as a means for preventing the forefoot of a wearer including the toes of said wearer from being hit by impacts or pushes by tools, constructional materials, debris, pieces of sports equipment etc..
  • the human foot due to its adaptation to the erect movement of a human, is an anatomically and functionally highly complex part of the body. Even minor mechanical influences to the muscles or bones of the feet result into major discomfort or even pain, and a physical injury to the feet may even have the consequence that a person has to refrain from walking, and thereby loose the possibility of movement, for the time of completely healing the injury. Having these facts in view, the working environment always emphasized protecting the feet of workers reliably, for example by suitable shoes. Wearing safety shoes or safety boots is, hence, an obligatory requirement in many areas where a risk exists that the feet may be harmed, for example in the steel industry, building industry, in the gardening and landscaping fields, for firefighters and rescue service people as well as for soldiers.
  • Safety shoes usually are midheight footwear made of leather and/or rubber or other polymers as, for example, polyurethane or thermoplastic polyurethane. Safety boots reach a height sufficient for protecting the foot including a part of the lower leg; they are made, in most of the cases, either of leather or of rubber (where protection against water is needed).
  • the sole of safety shoes/boots usually has an exposed profile for preventing the wearer from slipping and is often made of a high strength material in order to give the person wearing the shoe/boot a safe stand.
  • additional strengthening and puncture-preventing materials as, for example, steel plates or hard polymer parts made of, for example, Kevlar R of ParaAmide R are incorporated into the soles of safety shoes or safety boots.
  • Safety shoes or safety boots are usually provided with a protective cap made of steel, aluminum or high-strength plastics at their forepart in order to protect the toes against injuries resulting from heavy objects falling down.
  • the document US-A 2005/0,144,809 discloses a composite-reinforced toe cap for a shoe, which includes multiple composite fiber reinforcement layers and a larger fiber layer laminated between and extending out from the composite fiber reinforcement layers.
  • the fiber layer is made of continuous strands.
  • the composite fiber reinforcement layers are made of fiber-reinforced plastic composite materials, are laminated on the fiber layer to form a pre-product toe cap.
  • a bonding coating is applied to the fiber layer that extends beyond the composite fiber reinforcement layer to form a binding.
  • the pre-product is cured and has a binding that can be sewn to the sole, upper or tongue of a shoe.
  • a metal toe cap for safety shoes which includes an arcuate peripheral wall that tapers forward, a top wall, and a bottom wall defining a rear opening for receiving the toes of a user.
  • the peripheral wall and the top wall are connected by an upper arcuate transition section having a thickness that increases toward the top wall such that the top wall has a thickness greater than that of the peripheral wall. The impact-resisting property of the top wall is thus improved.
  • a parallel European patent application covering an invention also assigned to the assignee/applicant of the present application and filed on 21 August 2009 and having the Official File No. 09 168 387.0 relates to a toe protection cap for shoes which comprises an arcuate peripheral wall capable of covering the front part and the two side parts of the toe cap, a top wall and a bottom wall capable of covering the top and bottom parts, respectively, of the toe cap and being connected to said arcuate peripheral wall, said walls defining a rear opening for a user's toes to be accommodated in the space defined by said walls, wherein said top wall has a rearside edge having the shape of a letter "S" thereby allowing a protection of all toes of a user.
  • Preferred embodiments of said prior toe protection cap relate to a toe protection cap specified as above, wherein said top wall of the toe protection cap is provided with a number of holes regularly or irregularly, preferably regularly, distributed throughout its surface.
  • said toe protection cap has some of said holes, preferably the majority of the said holes, more preferably each hole in the surface of the top wall surrounded by a system of fillets strengthening the structure of said toe protection cap.
  • the holes may be made larger than in the toe protection caps proposed earlier, if the structure and arrangement of the fillets is maintained. Even the toe protection cap top wall surface areas filing the space between the fillets may be omitted by creating voids, thereby generating a very much improved ventilation, without that the stability and strength of the toe protection cap is diminished and with the effect that a safety of the forefoot and toes against falling tools/matters can be guaranteed.
  • the front and side parts of the toe protection cap may be provided with a similar ventilation by a system of fillets and holes, or omitted toe protection cap front and/or side wall surface areas, between said fillets, without that a loss of the stability and strength of the toe protection cap had to be observed.
  • a toe cap for a shoe allowing a reliable protection for the whole toe and forefoot area of the foot of a wearer or user.
  • a toe cap for a shoe allowing a greater comfort to the wearer or user than with conventional toe caps for shoes
  • the invention relates to a toe cap for shoes or boots or footgear comprising an arcuate peripheral wall capable of making up the front part and the two side parts of the toe cap, a top wall and a bottom wall capable of making up the top and bottom parts, respectively, of the toe cap and being connected to said arcuate peripheral wall, the rear edges of said walls defining a rear opening for a user's toes to be accommodated in the space defined by said walls, wherein at least said top wall is provided with a number of holes regularly or irregularly distributed throughout its surface, and each hole is surrounded by a system of fillets strengthening the toe cap, wherein said system of fillets at least in said top wall is existing as a closed network structure having said holes as void spaces between said fillets.
  • the invention also relates to shoes, boots and footgear comprising a toe cap of the invention as described below in detail.
  • Such shoes/boots may be safety shoes, protective shoes, occupation shoes, sports shoes, or corresponding boots or footgear to name only a few of shoes wherein the toe cap of the invention may be used, without, however, restricting the invention to those shoes.
  • Toe caps are usually made of plastics or of a metal or metal alloy and are mounted in a front end of a shoe, for example of a safety shoe, to withstand external impact and thereby protect particularly the forefoot, i. e. the toes of a foot of a user of the shoe and the consecutive part of the foot adjacent to the toes.
  • the "front" side of the toe cap is that part of the cap which is positioned at the front side of the shoe, or close to the toe tips of the user wearing the shoe with the toe cap.
  • the rear side of the toe cap is the side positioned, during use of the toe cap, opposite to the front side and "showing" to the middle part of the foot; the user enters into the toe cap (when the toe cap is entered into, or fixed within, the shoe) from the toe cap's rear side.
  • the "lower” or “bottom” wall of the toe cap is the wall on which, when in use, the foot of the user is positioned, while the “upper” or “top” wall of the toe cap is the wall opposite to the bottom wall of the toe cap; the upper side of the wearer's foot is adjacent to the toe cap's top wall.
  • the toe cap 1 of the invention comprises a peripheral wall 3 which is formed arcuate and which is capable of making up the front part 3a and the two side parts (left hand and right hand side parts) 3b, 3c of the toe cap 1.
  • the toe cap further comprises a top wall 5 and a bottom wall 7 which are capable of making up the top part 5a and the bottom part 7a of the toe cap 1.
  • the top and bottom walls 5, 7 are extending to, and are connected to, the arcuate peripheral wall 3 integrally along the front side and the left and right side of the toe cap 1 so as to form the toe cap 1.
  • This rear opening 8 opens a space for the accommodation of all the toes of one foot of the user, i.e. the toes of one foot of a user are accommodated in the inner space defined by said peripheral wall 3, top wall 5 and bottom wall 7.
  • the user's or wearer's foot enters the inner space defined by said peripheral wall 3 and the top and bottom walls (5, 7) by passing the rear opening 8.
  • the rearside edge 5b of the top wall 5, and preferably also the rearside edge of the bottom wall has the shape of a letter "S", which shape may be easily seen from Figures 1 and 2 .
  • the major advantage of such a shape similar to the letter "S" is the complete accommodation of all toes of one foot, and at least a part of the forefoot of the foot, of the user wearing the shoe with the toe cap 1 of the invention within the toe cap in a convenient and non-restricted manner. This is in contrast to the prior art, where mainly the large toes were sufficiently protected, while the small toes were not.
  • the toe cap 1 is constructed as having a number of holes 5c distributed at least throughout the whole surface of the top wall 5 either regularly or irregularly.
  • the term "regularly”, as used in the description and claims is intended to mean that the holes have a substantially identical distance to the next-neighboring hole(s) throughout the top wall 5 of the toe cap 1.
  • a (partly or completely) irregular distribution of the holes means that the distances of one hole to the next-neighboring hole(s) may be more or less (or at least partly) different.
  • a regular distribution of the holes 5c is preferred.
  • Such hole or holes 5c may serve a ventilation of the toe and forefoot area of the foot of the user wearing the shoe including the toe cap 1.
  • Such a ventilation not only improves the convenience of wearing such a shoe with a toe protection cap 1, but also prevents an accumulation of sweat and/or humidity in the inner space of the toe cap 1.
  • the latter may prevent the generation of bad smells due to a growth of smell-generating bacteria and the occurrence of diseases at the foot or, specifically, at the toes.
  • each hole 5c at least in the surface of the top wall 5 of the toe cap 1 is surrounded by a system of fillets 5d.
  • the fillets 5d around the hole(s) 5c the toe cap material loss, by the holes 5c, is compensated, and a strengthening effect is obtained.
  • the impact strength of the toe cap 1 is not deteriorated by providing the ventilation holes 5c.
  • said system of fillets 5d at least in said top wall 5 is existing as a closed network structure having said holes as void spaces between said fillets 5d.
  • the term "closed network structure”, as used in the present specification and claims, is defined to mean that the filets 5d, at least in the top wall 5 of the toe cap of the invention, and preferably in the top wall 5 and in the arcuate peripheral wall 3 as well, are connected to each other in a structure-stabilizing manner and combined with each other so that, by establishing said "closed network structure", a continuous system of fillets around said holes, or even around void spaces, is established the stability and strength of which is at least not substantially deteriorated, preferably is not deteriorated, compared to a structure having no holes surrounded by fillets formed at the top wall and/or the peripheral front and/or side walls.
  • such a closed network structure has said holes 5c as void spaces 5c between said fillets 5d.
  • void spaces as used throughout the present specification and claims, is defined to mean that the surface area or surface areas between the fillets 5d, for example the surface area of the top wall 5 and/or the surface area of the arcuate peripheral wall 3 making up the front part 3a and/or the right and left side parts 3b, 3c of the toe cap 1, is/are a void space or void spaces, i.e. have the material of the top wall 5 and/or of the arcuate peripheral wall 3 omitted between the fillets 5d. This can best be seen from the present Figures 1 , 2 , 4 and 5 .
  • At least said top wall 5 of the toe cap 1 of the invention is provided with a number of holes 5c regularly distributed throughout its surface.
  • said holes 5c are void spaces between said closed network structure of fillets 5d formed at least at the top wall 5 of said toe cap 1.
  • said top wall 5, i.e. the top wall 5 only is provided with a number of holes 5c regularly distributed throughout its surface, said holes 5c being void spaces between said closed network structure of fillets 5d formed at the top wall 5 of said toe cap 1.
  • a substantially improved ventilation of the user's toes and fore foot may be achieved, without decreasing the overall strength of the toe cap 1 against mechanical impact.
  • said arcuate peripheral wall 3, i.e. the arcuate peripheral wall 3 only, is provided with a number of holes 5c regularly distributed throughout its surface, said holes 5c being void spaces between said closed network structure of fillets 5d formed at the arcuate peripheral wall 5 of said toe cap 1.
  • a substantially improved ventilation of the user's toes and fore foot may be achieved, without decreasing the overall strength of the toe cap 1 against mechanical impact.
  • said top wall 5, and said arcuate peripheral wall 3 capable of making up the front part 3a and the two side parts 3b, 3c of the toe cap 1 as well, are provided with a number of holes 5c regularly distributed throughout their surface, said holes 5c being void spaces between said closed network structure of fillets 5d formed at the top wall 5 and at the arcuate peripheral wall 3 of said toe cap 1.
  • the ventilation is even more improved.
  • the additional holes/void spaces 5c in the arcuate peripheral wall 3 do not deteriorate the stability and strength features of the overall toe cap 1 at all.
  • said fillets 5d around the holes or void spaces 5c in the toe cap's top wall surface and/or in the toe cap's arcuate peripheral wall surface form a hexagon around each of the holes / void spaces 5c.
  • the hexagon type system of fillets 5d surrounds areas of the top wall surface and/or arcuate peripheral wall surface, which areas are void spaces.
  • a larger number of adjacent hexagons of fillets 5d form a honeycomb structure at the top wall surface and/or at the arcuate peripheral wall surface of the toe cap 1.
  • Such a honeycomb structure is capable of strengthening the toe cap against impacts despite the provision of ventilation holes 5c or void spaces 5d in the top wall surface and/or in the arcuate peripheral wall surface of the toe cap 1.
  • the same strength as in conventional toe caps can be obtained by providing the honeycomb structure of fillets 5d around each ventilation hole(s) 5c / void spaces 5c for ventilation.
  • said top wall surface and/or said arcuate peripheral wall surface has additional fillets 5e extending from one point at said rear side edge 5b of the top wall 5 and radially across the whole surface at least of the top wall 5.
  • radially extending is defined to mean that said point, at the rear side edge 5b of the top wall 5 of the toe cap 1, may be considered as being the center of a (theoretical) circle, and said additional fillets 5e have the origin in said circle center and extend from said center throughout the top wall surface radially towards the rim of said (theoretical) circle. This can easily be seen from Figures 1 , 2 and 5 . By such additional fillets 5e, the toe cap structure may be additionally strengthened.
  • the toe cap 1 has additional fillets 5e extending from one point located substantially in the middle, relative to said side parts 3b, 3c of the arcuate peripheral wall 3, at said rearside edge 5b radially across the whole surface of the top wall 5 and of the arcuate peripheral wall 3.
  • the number of such additionally strengthening fillets 5e is not particularly restricted, and a skilled person may select such number in accordance with the needs. It may be noted that an increasing number of such additional fillets 5e may contribute to an improvement of the strength, but may also adversely influence the ventilation properties, since the space available for voids for ventilation decreases. However, in further preferred embodiments of the invention, the number of such additional fillets (5e) extending across the whole surface of the top wall (5) and of the arcuate peripheral wall (3), and particularly preferably extending in equal angular distances to each other, is between three and five, as can best be seen in Figures 1 , 2 and 5 . By such additional fillets 5e arranged in equal angular distances to each other, the toe cap structure may be strengthened even further, and a good ventilation of the inner space of the toe cap according to the invention is nevertheless possible.
  • the arcuate peripheral wall 3 may be provided with strengthening fillets 3d on its inside, i. e. on the side directed to the inner space of the toe cap 1 directed to the toes of the wearer, in case that no hexagon fillet - void structure is provided at the arcuate peripheral wall 3 of the toe cap1 of the invention, although this is not a preferred embodiment.
  • additional fillets which may extend in the direction between the top and bottom walls 5, 7, of the toe cap 1
  • the strength of the toe cap 1 may be improved.
  • a toe cap 1 without such fillets 3d is preferred.
  • Omitting material, and thereby making the toe cap of the invention loose weight (which weight loss may be preferred for reasons of convenience of wearing the low weight toe cap 1), can be achieved, in accordance with another preferred embodiment of the invention, by an embodiment wherein said bottom wall 7 consists of a rim 7b extending from, and being connected to, the arcuate peripheral wall 3 along its front and two side parts 3a, 3b, 3c in a substantially perpendicular arrangement.
  • bottom wall 7 is no longer a full area bottom wall 7 but is only a rim along the lower end of the arcuate peripheral wall 3 extending from said arcuate peripheral wall 3, along its front and side parts 3a,3b, 3c, in an angle of more or less 90 °, allowing a convenient placement of the front parts of the toes of the user and of the respective side parts of the outer (left and right) toes and of the fore foot on said rim 7b.
  • said rim 7b is of a width allowing a convenient placement of the forefoot sole and underside of the toes on it, and in an even more preferred embodiment, the rim 7b is of a width within a range of from 0.5 to 5 centimeters (cm), without restricting the invention to such a value or to any value in the above range. No loss of impact strength of the overall toe protection cap has to be taken by such an embodiment of the invention.
  • the impact strength of the toe cap 1 is improved further by a toe cap of the invention wherein additional fillets 5f are provided along the upper and lower peripheral edges connecting the top and bottom walls 5, 7 to the arcuate peripheral wall 3.
  • additional fillets 5f may include fillets 5f along the rear side edge of the top and bottom walls 5, 7 and/or along the rear side edge of the two side parts 3b, 3c of the arcuate peripheral wall 3, i.e. at the rear side edges forming the rear opening 8 of the toe cap 1.
  • Such additional fillets 5f advantageously contribute to an improvement of the strength of the toe cap 1 as a whole.
  • the additional fillets 5e, 5f may comprise grooves 5g running within, and in parallel to, the additional fillets 5e, 5f. Such embodiments are shown in the Figures 1 , 2 and 5 .
  • the grooves take away material from the additional fillets 5e, 5f, i.e. contribute to a reduction of the overall weight of the toe cap 1 of the invention, and they do not harm stability and strength properties of the toe cap 1.
  • the material for toe caps 1 of the present invention may be selected by a skilled person in accordance with material selections made in the prior art, and the material may be adapted to the specific requirements in each single case.
  • a material may be used for manufacturing the toe caps 1 of the present invention which is selected from the group consisting of plastics, for example hard polymer materials like those used in the prior art, e. g.
