Definitions

  • the invention relates to a sports shoe, in particular a running shoe, with an elastically flexible heel cap arranged on the outside of the boot.
  • the heel steps which are usually made of a hard and rigid material and can be arranged on the inside or outside of the boot, provide the desired firmness of the heel in the shoe, but also have disadvantages .
  • These disadvantages consist in the fact that the hard heel caps in foot shapes that do not correspond exactly to the last shape of the shoe cause painful pressure points on the foot, which lead to blisters when used over a long period of time, for example in long-distance running. Regardless of the exact fit of the foot in the shoe, these phenomena occur to you when running on an uneven path, e.g. during training, jogging or running in the forest, because here a constant tilting of the heel, which is compensated by the ankle joint, is inevitable.
  • the intended purpose can only be achieved by accepting other disadvantages. If, despite the elastic flexibility of the rubber heel step, a sufficient support and helper effect is to be achieved, then the heel step must have a considerable turning star and thereby noticeably increase the weight of the sports shoe. If the wall thickness of the heel stepper is chosen to be low due to weight reasons, the heel stepper loses its essential function as a heel support because, due to its elasticity, it experiences a local expansion when subjected to lateral loads, so that it only - for example, if the heel is displaced sideways due to a bump in the web - only is still on one side at the foot.
  • the heel step is formed by a frame or lattice work made of a flexible elastic material.
  • the invention is thus based on the consideration that the elastic resilience of the heel step should not be obtained by choosing a material which is elastically flexible under tension, such as rubber, because this causes the heel step in the parts in which tensile stress occurs under a lateral load. expands locally and thereby loses its shape.
  • the invention avoids this phenomenon in that the heel stepper is made of a hard and therefore tensile, i.e. under tension practically inextensible, material exists, but which has a sufficient bendability, whereby a frame or lattice work is achieved by the formation of the heel step ice a sufficient lateral bendability.
  • the heel cap in the direction of the load in a certain measure, is known, but experiences no local expansion due to the choice of solid material, so that the side load of the heel step, which is not exposed, is at least partially is taken away.
  • Suitable as a tensile and elastic material for the heel step is the one that has already been used for the well-known heel steps, such as hard-set polyamide, polyurethane or the like. De to achieve a sufficient support effect the heel step according to the invention has a smaller wall thickness is known from the above The rubber heel steps are used to reduce the weight of the sports shoes overall.
  • the frame or lattice construction which essentially represents the load-bearing support structure of the heel counter according to the invention.
  • the general rule is that the heel step according to the invention is more flexible, ie its supporting effect is reduced, the larger the meshes of the openings provided in the reed or latticework.
  • it is advantageous to fill the openings with a tensile, flexible material for example a fabric or a net, which is firmly connected to the edge of the openings.
  • a tensile but flexible material links the bars or webs located between the openings without increasing the overall rigidity of the heel step.
  • the heel step has a frame with at least one closed-ended opening, which extends forward over the apex line on both sides.
  • there is only a certain rend area of a conventional hard heel step the bending stiffness of which is relatively low in both lateral directions. Due to the fact that the opening of the heel counter is filled with a tensile fabric or net, the thread of which is expediently arranged at an acute angle to the heel apex line, lateral bending forces are also transmitted to the flank of the heel step opposite to the direction of force, so that this also causes a deformation experiences and mix the other foot seixe stays in contact.
  • Figure 1 is a side view of a sports shoe with a first embodiment of a heel counter according to the invention.
  • the heel 1 has a shock-absorbing outsole 1 eus nechgiebigem plastic material, a shaft 2 and a heel step 3 euf attached to the outside of the shaft 2 in the heel area.
  • the heel step 3 is fixed by flat adhesive to the leg 2 and overlaps between the outsole 1 and leg 2 the not visible Zwickeinschi eg of the shaft 2 from below. It covers the shaft approximately in the heel apex area over a height of 2/3 of the shaft and extends to both sides of the shaft towards the front, tapering, to some extent in the joint area of the outsole 1 and in each fur to below the ankle of the user.
  • the heel step 3 consists of a ring 10 made of hard, tensile, but flexible plastic material, for example hard-set polyamide, which forms a closed-ended opening 11 or a recess.
  • the breakthrough 11 follows approximately the outer contour of the heel step 3, as can be seen in FIG. 1, and extends over the heel plate 1 inie euf both sides of the heel step 3.
  • the breakthrough 11 is a relative by an insert 12 eus flexible plastic material, for example polyurethane, filled, which has a lower turning strength ice of the reeds 10, and in which a net 13 eus tensile yarn is embedded.
  • the likes of the network 13 run, as can be seen in particular from FIG. 3, under one
  • the plastic embedding the net 13 is considerably softer * than the plastic forming the frame 10 and is primarily used to give the net 13 a certain shape retention, so that die ⁇ e ⁇ maintains the outline shape of the Fe rsenkep pe 13.
  • the heel step 3 has along its lower rend a flange 14 euf directed towards the inside, which, as mentioned above, engages under the tongue of the boot 2 in the inserted condition of the heel step.
  • the flange 14 has a series of notches 15 which allow the heel step to bend in the plane of the drawing in FIG. 4 in order to be able to better handle the heel cap and to adapt it to the heel shape of the last.
  • the width a (FIG. 3) of the frame 10 is normally 8 to 15 mm, preferably 10 mm; the wall thickness of the frame is usually 1 to 1.5 mm, preferably 1.5 mm.
  • 5 to 8 show averting the heel step, which is also based on the principle according to the invention, to ensure the elastic compliance of the heel step by virtue of the fact that its essentially load-bearing part is a “framework” or a supporting structure, which, although deforming elastically, does can never be stretched under tensile stresses.
  • 5 and 6 shows a shape 20 defining the outline of the heel step, the upper part of which is connected to the lower part by a type of fencing mechanism made up of a plurality of vertical rods 21 and 22 and 23 which run obliquely to the vertical , 24 is connected.
  • the essentially vertical rods 21, 22, which are each provided in pairs, are formed by an opening 25 located in the area of the Achilles tendon attachment or by three smaller openings 26 arranged underneath.
  • Breakthroughs 27 and 28 in the side walls of the heel step form the bar 23 which extends obliquely at the front and, together with the two outer openings 26 in the heel area, the bar 24 which extends obliquely at
  • the lower part of the frame 20 has a flange projecting from the inside, not shown, which engages under the lasting fold of the sports shoe.
  • a continuous floor which is curved according to FIGS. 5 and 6 in the transition to the rear of the heel step, is more expedient.
  • the breakthroughs can be 25 to 28 with A fabric or net made of tensile material fills ⁇ ein, as is explained in conjunction with the first embodiment, which is firmly connected to the edges of the openings. This connection is expediently achieved by direct pouring in during the production process of the ring mechanism forming the heel step.
  • the embodiment according to FIGS. 7 and 8 also has a ring 30, which, however, essentially only determines the shape of the side turn of the heel step. 5, 6, the side walls here are not connected to one another at their rear upper end, but are separated from one another by an open aperture 31 which opens the Achilles tendon insertion and the Achilles tendon.
  • the side turn of the heel steppe is connected to one another by a heel piece 32 which forms a quarter ball and in which 33 horizontal bars or horizontal arches 34 are formed by four transverse slots.
  • the upper end of each side wall can first be deformed to a certain extent, i.e. bend without exerting a reaction on the opposite side turn.
  • the transverse arches 34 act as coupling links, which each track the opposite side wall in the same direction of deformation.
