Definitions

  • the invention relates to a footwear sole structure comprising an insole having a forefoot area and a puncture protection, which comprises a first puncture protection element extending substantially over the entire area of the insole of the footwear.
  • the invention further relates to footwear having an upper structure and a sole structure.
  • Puncture resistant footwear is used as work shoes or boots, in particular on construction sites, where it provides protection for the foot, for example when stepping on a nail.
  • the nail protection typically comprises a steel midsole placed in the sole structure of the footwear, which covers the entire bottom of the footwear and thus provides protection to the entire sole of the foot.
  • Such a sole structure with a steel midsole is quite rigid.
  • the puncture protection is made of a flexible puncture resistant fabric. In most cases, the puncture resistant fabric provides adequate puncture protection, but it does not provide the same level of protection as a puncture protection plate made of steel.
  • FI 105460 B describes a puncture resistant, ventilated sole structure for footwear, which comprises flexible puncture protection extending over the entire area of the sole of the foot.
  • the object of the invention is to provide a sole structure for footwear and footwear with which the problems associated with known solutions can be reduced.
  • the invention relates to a footwear sole structure comprising an insole having a forefoot area and a puncture protection, which comprises a first puncture protection element extending substantially over the entire area of the insole of the footwear.
  • the puncture protection further comprises at least one second puncture protection element such that the first and second puncture protection elements at least partially overlap.
  • the sole structure thus has an area where two puncture protection elements overlap. It is obvious that in this part of the sole structure the puncture protection is clearly better than in an area with only one puncture protection element.
  • the first puncture protection element is flexible. By the flexibility of the puncture protection element it is meant that it bends and at least partially adapts to the shape of the foot in the footwear during the act of walking.
  • the first puncture protection element has holes at least in the forefoot area of the insole. The holes allow water vapor to pass through the puncture protection element.
  • the first puncture protection element is a puncture protection made of a fabric.
  • the first puncture protection element is integrated into the insole.
  • the first puncture protection serves as an insole of the footwear.
  • the first puncture protection element is a flexible plate made of metal, plastic or composite material.
  • the second puncture protection element extends substantially only in the forefoot area of the insole.
  • the second puncture protection element may extend substantially over the entire area of the insole.
  • the second puncture protection element is a flexible plate made of metal, plastic or composite material.
  • the second puncture protection element may be a flexible puncture protection made of a fabric.
  • the second puncture protection element is non-perforated.
  • the second puncture protection element preferably extends into the perforated area of the first puncture protection element. The second puncture protection element thus ensures the protective effect of the puncture protection element also at the holes of the first puncture protection element.
  • the honeycomb extends substantially only in the area of the second puncture protection element.
  • Yet another preferred embodiment of the sole structure according to the invention further comprises an outsole with an outflow channel, which outflow channel is connected to the honeycomb.
  • Footwear according to the invention has an upper structure and a sole structure, which is a sole structure according to one of the above.
  • An advantage of the invention is that it achieves better puncture protection for the desired area of the sole of the foot.
  • the enhanced puncture protection is implemented in such a way that it does not reduce the ventilation in the footwear, i.e. the invention does not impair the comfort of the footwear.
  • Another advantage of the invention is that the improvement of the puncture protection does not impair the flexibility of the sole structure.
  • Fig. 1 shows an exploded cross-sectional view of footwear with a ventilated sole structure.
  • the footwear has an upper structure 1, an insole 2 and an outsole 4.
  • the insole 2 is perforated 5.
  • a water vapor permeable vapor membrane 3 which may be, for example, a membrane sold under the trade name GORE-TEX®.
  • a honeycomb 8 made of an air-permeable fibrous material in the form of a single piece. Puncture protection 10 is sandwiched between the honeycomb and the outsole.
  • the honeycomb 8 is approximately the same size and shape as the vapor membrane 3. It preferably covers the front part of the outsole and suitably extends to the edges 7 of the upper structure at the toe and front section of the footwear.
  • the honeycomb 8 may be made of wool, man-made fiber or the like, from which a felt-like, air-permeable body of material has been formed.
  • the honeycomb may be impregnated with an impregnating agent used in the textile and clothing industry to be water-impermeable and non-water-absorbent.
  • Such a honeycomb 8 made of a felt-like material is particularly suitable for footwear in dry conditions.
  • the thickness of the honeycomb is chosen so as to achieve adequate ventilation of the footwear. In the case of a honeycomb impregnated with an impregnating agent, no water vapor permeable vapor membrane is required.
  • the sides of the outsole 4 have substantially horizontal flow channels 9 extending from the outer surfaces of both sides to the lateral edges of the honeycomb, thus providing a ventilation connection between the outside air and the inside of the footwear through the air permeable honeycomb 8, the vapor membrane 3 and the holes 5 of the breathable insole 2.
  • the honeycomb is attached directly to the upper surface of the puncture protection 10.
  • the moisture formed inside the footwear escapes through the air-permeable structure formed by the holes 5 in the insole, the vapor membrane 3 and the honeycomb 8 into the flow channels 9 in the outsole and from there to the outside air.
  • the honeycomb undergoes a certain degree of compression and during the leg lifting phase, the honeycomb returns to its original state. This movement creates a pumping effect on the honeycomb, which enhances the ventilation of the footwear.
  • Both the honeycomb 8 and the vapor membrane 3 are well protected from external substances by means of the outsole 4 and cannot be affected by dirt, sand, shards or the like on the ground.
  • the puncture protection 10 acts as an additional protection for the honeycomb and the vapor membrane and does not prevent the ventilation of the footwear.
  • the footwear shown in Fig. 1 is best suited for use in dry working conditions. If the footwear became completely wet on the outside or inside, the felt-like honeycomb 8 could also get wet and would require a long time to dry. In completely dry working conditions, for example in a paper mill, it is possible to use footwear without a vapor-permeable membrane 3. In such conditions, the water-impermeability property of the vapor membrane is not required, and the vapor-permeability property of the vapor membrane is also found in the perforated insole.
  • Fig. 2 shows an exploded cross-sectional view of a second item of footwear with a ventilated sole structure.
  • the footwear shown in Fig. 2 differs from the footwear according to Fig. 1 in terms of the honeycomb in that the honeycomb 8 is formed of a moldable material.
  • a material is, for example, rubber, PU, PVC, TR or the like.
  • the honeycomb 8 is manufactured separately, preferably by direct injection molding.
  • the honeycomb 8 has grooves 20 and ridges 21 in the longitudinal direction of the footwear and is surrounded by an edge 22 and a groove 23 inside it.
  • the puncture protection 10 is arranged on the lower surface of the honeycomb 8. Also in this honeycomb, there occurs a ventilation-enhancing pumping effect when the honeycomb is slightly compressed when taking a step and returns to the normal position during the leg lifting phase.
  • the honeycomb 8 shown in Fig. 2 is particularly suitable for footwear intended for wet conditions, because it does not get wet in the same way as the felt-like honeycomb according to Fig. 1 .
  • the structure of the footwear is similar to that shown in Fig. 1 , with the same reference numerals being used in the description for identical parts.
  • the ventilation-enhancing portion extends only to the area of the forefoot, which is the part most prone to moisture caused by sweating. However, it can be extended over the entire area of the foot, with the insole being perforated over its entire area and the honeycomb and any vapor-permeable membrane covering the entire lower surface of the insole.
  • honeycomb structures Two different honeycomb structures have been shown above by way of example: a porous honeycomb 8 made of a fibrous material, and a honeycomb provided with channels, which is made of plastic, rubber or the like.
  • the honeycomb structure of the latter type is preferably manufactured by injection molding and naturally can be shaped in many different ways.
  • the ridges and grooves may be continuous or discontinuous, zigzag-shaped or wavy.
  • the honeycomb is usually located only at the front of the footwear, extending to the edges 7 of the upper 1, which are folded under the insole 2. However, it can be extended all the way to the heel and widened to extend to the side of the outsole in designs where the upper is not folded under the insole but the insole is secured by stitching.
  • Figs. 3a, 3b and 3c show by way of example a puncture protection used in the sole structure of footwear according to the invention.
  • Fig. 3a shows the puncture protection seen from above, Fig. 3b seen from below and Fig. 3c seen from the side.
  • the puncture protection comprises a first puncture protection element 28, a second puncture protection element 30 and a honeycomb 8.
  • the first puncture protection element is made of a flexible puncture protection fabric and is substantially the same shape as the insole of the footwear.
  • the first puncture protection element can be arranged to extend, within the sole structure of the footwear, over substantially the entire area of the sole of the foot.
  • the puncture protection fabric used in footwear comprises a material which, as such, is known in the art, so it will not be described in more detail here.
  • the forefoot area of the first puncture protection element aligns with the ball of a foot fitted inside the footwear.
  • the first puncture protection element has holes 34 in the forefoot area, which allows air and water vapor to flow through the puncture protection element.
  • honeycomb 8 On the lower surface of the first puncture protection element, at the forefoot area 32, there is a honeycomb 8 ( Fig. 3c ) which allows the footwear to be ventilated.
  • the honeycomb can be, for example, a felt made of fibers or, for example, a plate-like body made of rubber, polyurethane, PVC or the like.
  • the honeycomb is a honeycomb as shown in Figs. 1 or 2 .
  • the second puncture protection element 30 On the lower surface of the honeycomb 8, there is a second puncture protection element 30.
  • the second puncture protection element is a metal plate.
  • the second puncture protection element is intact throughout, i.e. it does not have through holes.
  • the second puncture protection element enhances the puncture protection, in particular at the forefoot area, where the first puncture protection element 28 has holes which weaken the puncture protection.
  • the puncture protection according to the invention thus combines a flexible fabric-based and plate-like puncture protection in the forefoot area of the footwear and at the same time provides double protection in this area.
  • the footwear however, remains comfortable to wear as the plate-like second puncture protection element extends only in the forefoot area and the footwear can otherwise adapt to the movements of the foot and the contours of the ground or floor.
  • the holes 34 of the first puncture protection element 28 and the honeycomb 8 below the forefoot area allow the footwear to be ventilated.
  • the puncture protection element according to the invention can also be implemented in such a way that the plate-like second puncture protection element 30 extends over the entire area of the insole of the footwear. This provides double puncture protection for the entire sole structure. Good ventilation of the footwear is achieved by arranging holes 34 in the first puncture protection element over the entire area of the puncture protection element and extending the honeycomb 8 over the entire area of the insole.
  • the puncture protection element according to the invention can also be implemented in such a way that the second puncture protection element is formed from a puncture protection fabric instead of a plate, which extends over the entire area of the insole. This results in footwear that is very comfortable to wear, with an additional double puncture protection over the entire insole area combined with a ventilated sole structure. Also in this embodiment, it is possible, but not necessary, to extend the perforation and honeycomb of the upper first flexible puncture protection element to the entire area of the insole. It is also possible to form the first puncture protection element from a flexible metal, plastic or composite plate. In that case, the second puncture protection element may comprise fabric-based puncture protection or a puncture protection element made of a flexible metal, plastic or composite plate.
  • the puncture protection element according to the invention can also be implemented in such a way that, instead of a plate, a piece of puncture protection fabric is arranged below the forefoot area of the first puncture protection element, which extends only in the forefoot area of the first puncture protection element. This provides double flexible puncture protection for the forefoot area.
  • Fig. 4 shows an exploded cross-sectional view of footwear with a sole structure according to the invention.
  • the footwear has, as is known, an upper structure 1, a perforated insole 2 and an outsole 4.
  • a water vapor permeable vapor membrane 3 which may be, for example, a membrane sold under the trade name GORE-TEX®.
  • a puncture protection 26 as described above, comprising a first puncture protection element, a second puncture protection element and a honeycomb between them.
  • the honeycomb may be any known honeycomb used in ventilated footwear, such as the honeycomb shown in Figs. 1 or 2 .
  • the sides of the outsole 4 below the puncture protection have flow channels 9 extending from the outer surfaces of both sides to the lateral edges of the honeycomb.
  • the flow channels together with the honeycomb, holes of the first puncture protection element, the vapor membrane 3 and the holes of the insole 2 form a ventilation connection from the inside of the footwear to the outside of the footwear.
  • Fig. 5 shows an exploded cross-sectional view of footwear with a preferred embodiment of the sole structure according to the invention.
  • the footwear has, as is known, an upper structure 1, an insole 2 and an outsole 4.
  • the first puncture protection 28 with holes 34 is located in the conventional insole location and serves simultaneously as both a puncture protection and insole of the footwear.
  • Below the insole there may be a water vapor permeable vapor membrane 3.
  • Below the vapor membrane there is a felt-like honeycomb 8 used in ventilated footwear and known per se.
  • the honeycomb may be impregnated with a water-repellent substance or made of a water-repellent fibrous material, in which case a separate vapor membrane above it is unnecessary.
  • Below the honeycomb there is a second puncture protection 30, which may be made of a puncture protection fabric, metal or composite material.
  • the footwear shown in Fig. 5 is well suited for use in wet conditions as well.
  • Fig. 6 shows an exploded cross-sectional view of footwear with another preferred embodiment of the sole structure according to the invention.
  • the footwear has, as is known, an upper structure 1, an insole 2 with holes 34, and an outsole 4.
  • Below the insole there is a perforated 34 first puncture protection 28.
  • the holes in the insole and the holes in its first puncture protection are preferably substantially aligned with each other.
  • Below the first puncture protection there is a felt-like honeycomb 8 used in ventilated footwear and known per se.
  • the honeycomb is impregnated with a water-repellent substance or made of a water-repellent fibrous material.
  • a second puncture protection 30 which may be made of a puncture protection fabric, metal or composite material.
