Definitions

  • the invention relates to a safety shoe with a toe cap, which has a shape substantially adapted to the tip of a shoe and facing the sole has an inwardly directed flanged edge, in which the flanged edge of the toe cap is inserted into a groove arranged in the vertical end face of the sole tip and by means of the Upper part is held therein, the upper groove wall being set back from the lower groove wall by at least the thickness of the toe protection cap and the upper part being connected to the lower groove wall.
  • Such a safety shoe is known from DE-OS 23 40 146 and has the advantage that the toe cap, which mostly consists of metal, does not have to be fastened to the sole by means of separate fastening parts.
  • the flanged edge inserted into the groove of the sole holds the toe cap in the direction perpendicular to the tread of the sole and the upper part which is then connected to the sole then fixes the toe cap permanently and captively to the sole.
  • the sole is composed of a lower part and an upper part.
  • a shoulder is formed on the upper edge of the lower part, which is surmounted by the upper part, so that the groove for the flanged edge of the toe cap is formed.
  • This composite sole makes the production of the safety shoe more expensive.
  • Another disadvantage of this known safety shoe is that the toe cap even after attaching the upper in the Only has a game and is not stuck.
  • the toe cap must also be held when attaching the upper to the sole, which complicates the manufacture of the safety shoe, at least at the beginning of the attachment of the upper.
  • the groove is made in a solid sole, the width and / or the depth of the groove having (a) smaller dimension (s) than the thickness and / or the width of the flanged edge and that the flanged edge of the toe cap is pressed into the solid sole up to the stop of the toe cap on the end face of the upper groove wall and is thereby held nail-proof in the groove.
  • the groove can already be provided during manufacture, for example in the form (for example plastic sole), or only the groove needs to be milled (wooden sole), whereby the dimensions must be taken into account.
  • the easiest way to ensure this is that the groove with the recessed upper groove wall and the shoulder on the lower groove wall with an appropriately designed shape or milling cutter is introduced into the vertical end face of the solid sole in one operation.
  • the toe cap can then be pressed into the solid sole in the manner of a nail, the groove walls causing the flange edge to jam and / or the groove base being deformed by the flange edge.
  • the toe cap is fully inserted on the front surface of the upper groove wall presses, then the toe cap is adequately held on the solid sole and the toe cap no longer unintentionally loosens during further operations, in particular when attaching the upper part to the solid sole.
  • the work steps in the manufacture of the safety shoe are much easier to carry out than the known safety shoe, which is reflected in reduced manufacturing costs.
  • the lower groove wall of the toe protection cap has a front shoulder, meanwhile the vertical section is flush with the outer surface of the toe protection cap, then the upper part can be turned over directly to the vertical section of the heel at the bottom without the lower edge Groove wall are connected, which also has a cost-reducing effect on the manufacturing process.
  • the pressing of the flanged edge into the groove base of the groove can be facilitated in one embodiment in that the flanged edge of the toe cap ends in a point.
  • the flanged edge is sawtooth-shaped, the tooth tips being arranged at an angle such that they penetrate into the groove base of the solid sole in the longitudinal direction.
  • the vertical dimension of the upper groove wall corresponds approximately to the thickness of a preferably anatomically shaped insole.
  • the upper groove wall has sufficient strength to withstand the stresses that occur when the toe cap penetrates the groove in the solid sole.
  • the vertical section of the shoulder on the lower groove wall is approximately 10 mm wide.
  • a clean end of the safety shoe in the area of the sole tip is achieved in that the lower groove wall outside of the heel is flush with the outer surface of the upper part fastened to the vertical section of the lower groove wall.
  • the groove in the solid sole is extended in the direction of the middle part of the solid sole and accommodates a midfoot protective cap provided with a flanged edge before the toe protective cap is fixed in the groove.
  • a further embodiment provides that the vertical section of the heel extends beyond the groove at least over the entire fastening surface of the upper part.
  • a one-piece wooden sole 10 is used as the sole, which is anatomically adapted to the shape of the foot on the top 11 and can also be provided with non-slip coverings or the like in the area of the tread.
  • the toe cap 20 is also commercially available and defines the receiving space for the toes.
  • the lower edge of the toe protection cap 20, which is preferably made of metal or a similarly strong material, is angled inwards and designed as a flanged edge 21.
  • the shape of the wooden sole 10 and the toe cap 20 are matched to one another. In the area of the sole tip, the groove 12 is milled into the vertical outer surface of the wooden sole 10.
  • the upper groove wall 13 and the lower groove wall 19 are divided.
  • the width and / or the depth the groove 12 is now deliberately chosen to be smaller than the thickness and / or the width of the flanged edge 21 of the toe protection cap 20.
  • the upper groove wall 13 is removed at the end by the thickness of the toe protection cap 20, as can be seen from the end face 14.
  • the toe cap 20 is inserted with the flanged edge 21 into the groove 12 and pressed into the wooden sole 10 until the toe cap 20 abuts the end face 14 of the upper groove wall 13.
  • the flanged edge 21 can be clamped between the groove walls 13 and 19 and / or the flanged edge 21 can be pressed into the groove base, this depends on the dimensioning of the width and / or depth of the groove 12.
  • the toe cap 20 fastened in this way to the wooden sole 10 is already clearly held to it and this without additional fastening parts.
  • the toe cap 20 therefore no longer needs to be held in place, which considerably simplifies and simplifies the further operations compared to the operations in known safety shoes.
  • the lower groove wall 19 has the shoulder 16 facing the end of the groove 12, the vertical section 17 of which is flush with the outer surface of the toe cap 20 pressed into the groove 12.
  • the upper part 22 can therefore be connected directly to the vertical section 17 of paragraph 16 without folding the lower edge, as indicated by the fastening parts 23.
  • the end surface 18 of the lower groove wall 19 which is not occupied by the upper part 22 is flush with the outer surface of the upper part 22 fastened to the wooden sole 10.
  • the groove 12 can have a lateral extension 23 directed towards the central part of the wooden sole 10, which can accommodate a metatarsal protective cap with a corresponding flanged edge before the toe protective cap 20 is pressed into the groove 12 of the wooden sole 10.
  • the shoulder 16 with the vertical section 17 extends beyond the groove 12 and forms a stepped fastening surface in the entire area of the upper part 22.
  • the type of upper part 22 can be chosen freely without impairing the attachment of the toe cap 20 if only the groove 12 with the groove walls 13 and 19 is designed accordingly.
