Definitions

  • the invention relates to a toe cap for safety shoes or boots, consisting of a one-piece fitting made of metal that the Forefoot surrounds and arranged in the above and on the side of the foot Areas by at least one extending transversely to the longitudinal direction, Continuously trained bead is reinforced, extending to the bottom of the molding extends.
  • Such toe caps arrive in protective shoes and boots Application. They are designed to keep the toes of the wearer from outside To protect impact and impact effect.
  • Toe caps are usually made of tempered steel, recently also made of fiber-reinforced plastics or plastic composites.
  • the protective effect achieved is determined by adding a load to a falling mass is made or by a pressure test between plane parallel plates.
  • test conditions for safety shoes which are the highest according to the standard Represent safety level, see a falling energy of falling mass of 200 joules in front.
  • the aim is that the toe cap in Following an appropriate test at the rear edge of a certain minimum residual height, based on the footprint having.
  • Plastic toe caps essentially by a very large wall thickness in the front area of the cap and a greater internal height achieved. That's it also known, the wall thickness by molded plastic ribs to increase in size, which has a consistent depth along its entire length and a have matching cross-section.
  • the toe cap of the type mentioned is from DE GM 94 11 460.9 known. It is made of steel and is used to improve the mechanical Resistance at comparatively reduced weight with provided bead-like deformations. The deformations are on their whole Length of matching cross-section. The profile is in all sections arched.
  • Plastic toe protective caps have a protection against steel toe caps of this type a reduced by about 45% weight. While one Steel toe cap generally weighs 90 g / piece, that is Comparative weight of a plastic toe cap with 50 g / piece clearly lower. The naturally much lower values of the modulus of elasticity The plastics compared to steel require some constructive Take measures to achieve the necessary stability. at Plastic toe caps result from voluminous forms that the Visually adversely affect shoe.
  • the invention is accordingly based on the object, a toe cap made of steel to evolve so that one with the weight of Plastic toe caps comparable weight results in a known steel toe caps comparable stability at the side Load as well as a reduced volume.
  • a particularly good load capacity is obtained when the bead of the Form piece has a trapezoidal profile.
  • the bead can be at least in the substantially horizontally extending areas an arcuate have decreasing depth. It is particularly easy to get into Add footwear that meets the high standards of appearance becomes.
  • the profile of the beads is between the points where a sharp-edged Direction change is provided, designed as flat as possible. This will the static load capacity substantially increased, which in terms of the solution of task of the invention is essential.
  • the bead can in the course of substantially perpendicular Sections have a substantially consistent depth. These areas are relevant only in vertical during the prescribed tests Direction burdened. They are capable of such burdens through this training in particularly good way to withstand.
  • a plurality of beads are provided, which extend substantially parallel to each other and the shaped piece in the region of the beads optionally corrugated sheet-like shape. The deformation resistance is thereby further increased.
  • the maximum depth of the Rear area arranged beads is less than the maximum depth of the arranged at the front of beads.
  • the transition zones in the not armored areas are easier to hide.
  • At least one more Beading is provided, which extends substantially in the longitudinal direction and one of the bead has corresponding profile.
  • the further bead and the foremost Beading can be formed T-shaped into one another. At a appropriate training they can each other particularly advantageous in to complement their supporting action.
  • a significant improvement in wearing comfort can be achieved if the Shaping at least in the area of the bead and / or the further beads of in each case at least one ventilation opening is penetrated.
  • several ventilation holes provided by circular boundary are, with a diameter that is at most 5 times the thickness of the fitting.
  • the front end of the fitting is free from ventilation holes to the unwanted ingress of foreign bodies through the ventilation openings in the interior of the shoe to prevent.
  • the Support elements can be inserted supporting elements to the deformation resistance against vertical loads further increase.
  • the Support elements are expediently made the same material as the fitting, for example made of sheet steel.
  • she are preferably permanently connected to the fitting, suitably by a gluing, welding or riveting.
  • the number will be decisive determined by the load to be absorbed. Depending on the number Thus, an adaptation to a variety of requirements can be made.
  • the toe caps shown in the drawings are for Safety shoes or boots intended. They consist of one uniform piece of metal, which encloses the forefoot and the at least in the above and arranged on the side of the forefoot areas by at least one extending transversely to the longitudinal direction, continuously trained bead is reinforced, extending to the bottom of the fitting extends, wherein the bead from the center 4 of the molding 1 starting a has decreasing depth H on both sides. Accordingly, the cross section of Beading, starting from the middle, gradually decreasing in the lateral direction. It thus has a substantial extent over its entire width consistently high load capacity.
  • At the bottom of the fitting is the first bounded by an inwardly facing flange 7. The flange 7 causes a stiffening of the lower end of the molding 1 against a lateral evasion with vertical load from above.
  • the toe cap is in intended use in Safety shoes or boots inserted or embedded in the wall and the eye of the beholder through the upper of the safety shoe or -stiefels withdrawn.
  • the volume of the toe cap is comparatively reduced. It is therefore no longer easy recognizable that it is the footwear equipped with it Safety footwear acts. The acceptance in use is thereby clearly improved.
  • the comparatively reduced weight also has an effect positive in this regard.
  • the bead 3 may have a trapezoidal profile, as shown in Fig. 3. It is between the places where a sharp-edged change of direction the profile is provided, as even as possible, in this example, even completely flat, educated. As a result, the static load capacity is significantly increased. The Toe cap reaches its maximum when trained Load capacity.
  • the bead has 3 on her entire length an arcuate decreasing depth H.
  • the insertion in the Footwear is made easier.
  • the bead 3 has an arcuately decreasing depth H only in the essentially horizontally extending regions, and a substantially constant depth H 2 in the sections which adjoin one another on both sides and extend substantially perpendicularly.
  • Such a design is able to withstand the safety regulations prescribed pressure load test with a falling load in a particularly good manner.
  • Figs. 3 and 4 embodiments are shown, in which several 3 beads are provided, which are substantially parallel to each other extend.
  • the fitting 1 in the region of the beads 3 corrugated sheet-like designed.
  • Fig. 3 it can also be seen that the maximum depth T 1 in the rear Area arranged beads 3 is less than the maximum depth T 2 of the 3. Also, this is a training that helps to insert the toe caps in fashionable footwear to facilitate.
  • Fig. 4 it can also be seen that a plurality of further beads 3 'are provided and that the further beads 3 'are the center of the front end of the Shaping shaped piece 1 in a radial manner. Even at a load obliquely from In the front this achieves the desired, high deformation resistance.
  • the beads 3 are each of Ventilation holes penetrated, mainly from three to four Ventilation openings.
  • the ventilation of the interior of a shoe will This improves what it takes to achieve good wearing comfort Advantage is.
  • the individual ventilation openings 5 are in this embodiment of circular boundary. They have a diameter that is 3 to 6 times as is great as the thickness of the fitting 1. It was found that especially if this area is adhered to, no significant value Impact of deformation resistance occurs, compared with a Version that is free of ventilation holes. Nevertheless, that contributes Presence of the ventilation openings significantly contributes to the interior of the shoe during use free of jamming wetness and to improve the wearing comfort. In the front area of the execution after 4, no ventilation openings are provided. Injuries by It penetrates externally penetrating, pointed bodies.
