The invention relates to an anti-skid heel for street shoes with one at a certain distance from the heel running surface arranged in it, having ice spikes and in the heel running surface provided holes through which the ice thorns when the heel is loaded accordingly step through when the ground is soft enough to allow the ice thorn tips to penetrate.

Such heels have the purpose of walking on covered with crusty snow or ice To enable roads and paths, with the protruding from the heel tread through the through holes The tips of the ice thorns cling to the ice to prevent slipping. Such paragraphs equipped with ice thorns, which by means of appropriate arrangements when walking Smooth roads are pressed out of the tread, are known in various designs.

According to an older proposal, the support plate carrying the ice thorns is in use by means of a slider with beveled edges against the force of the support plate normally after above pressing spring pressed down, so that the ice thorns protrude from the paragraph. To Another suggestion is a spring loaded sliding wedge in the paragraph, which in the normal case, d. H. on normally walkable streets and paths, under the support plate of the ice thorns grips and thereby keeps it away from the heel running surface, while the wedge is smoother when walking on Streets, so when in use, is pushed over the carrying surface and thereby the ice thorns the heel tread pushes out. Another suggestion is to attach the ice thorns to a kind of crankshaft to arrange and to store this shaft rotatably so that the mandrels in use from the Step out heel running surface while swiveling the crankshaft in the normal case Paragraph be swiveled back. Finally, another anti-skid has become known at which the support plate carrying the ice thorns is attached to the leather heel of the footwear and A slot or through-hole corresponding to the arrangement of the ice spikes is then made via this support plate having rubber heel is nailed, the thickness of which corresponds to the length of the mandrel.

While in the first-mentioned training of anti-skid heels for street shoes, the ice thorns in use by more or less complicated and therefore damage-prone actuating elements Pushed out of the heel tread Anti-slip heel for street shoes

in the latter training the tips of the ice thorns penetrate when walking on a surface, which allows penetration of the mandrel tips, as a result of the compression of the soft, resilient ones Sales volume, d. H. So the rubber heel, due to the weight of the pedestrian on it out of the heel tread. Even when walking on a road or path that is not icy, it is at rest However, in this training the weight of the pedestrian on the tips of the mandrels, so that this is can wear out relatively quickly. In addition, the emergence of the mandrel tips from the heel running surface determined by the compressibility of the rubber heel. Another disadvantage of this training is that when walking on wooden floors or floors covered with plastic, the spike tips step out of the heel running surface and damage such floors.

In view of these various disadvantages of the proposed solutions so far, the proposal goes Invention then, the support plate for the ice thorns on the upper wall of a cavity in the paragraph to be arranged, the lower wall of which forms the heel running surface and in this cavity an insertable, Provide fork-like intermediate part to deactivate the effectiveness of the ice thorns.

In a preferred embodiment of an anti-skid heel of the type described above the support plate has three ice spikes and the intermediate part that can be inserted for the cavity has four a crosspiece with an external handle

tied parallel fork arms, the spaces between which absorb the ice spikes when pushed in. The advantages of such a design are that in the normal case, i. H. with inserted in the paragraph Intermediate part, the tips of the ice thorns are far enough away from the heel tread, so as not to be able to step out of it under any circumstances. So you can't wear yourself out, and you can With such footwear easily enter living rooms without having to fear that the Floor covering is damaged. However, as soon as the intermediate part is pulled out of the paragraph in use becomes, the now hollow paragraph, regardless of the type of natural or used Synthetic rubber compound, bend under the weight of the pedestrian, so that the ice thorns are far out of the Step out the tread and result in excellent anti-slip protection. The production of such a Heel is not associated with any particular difficulties, since the support plate with the ice thorns can be vulcanized directly into the paragraph using a corresponding core shape. The production of the intermediate part does not present any difficulties either, since it is a simple, is a molded part that can be produced in one operation. A preferred embodiment of the invention is explained in detail below with reference to the drawing; it shows

F i g. 1 the bottom view of one with the invention Anti-slip heel of equipped shoes for normal use,

F i g. 2 shows a section through FIG. 1 rotated by 180 ° along the line H-II,

F i g. 3 the same view as FIG. 1, but with the intermediate part pulled out for use, and

F i g. 4 shows a section through FIG. 3 rotated by 180 ° along the line IV-IV.

The heel 1 shown in the figures has, as is particularly clear in FIG. 4 can be seen a cavity 23, on the upper wall of which a support plate 35 with ice thorns 19, 20, 21 is attached is. The heel running surface forming the lower wall of this cavity is corresponding to Arrangement of these ice spikes perforated so that the spike tips are just above holes 32, 33, 34. For the normal case is a fork-like intermediate part with fork arms in the recess 23 of the paragraph 36, 37, 38, 39 and one connecting these arms and having a handle 30 on the outside Cross piece 29 inserted, which is expediently stuck in the shoulder due to its own friction, even if special locks can be provided. This intermediate part lies down from above against the inner surface of the shoulder wall so that it does not sag under load and the spike tips can therefore not pass through their holes.

ίο You walk on the heel in this state like on a normal rubber heel, without the risk of the thorns or any wear Damage to the walked-on area. For the case of use, the intermediate part is simply removed from the Heel pulled out and tucked into pocket. This creates the perforated lower wall of the heel no longer supported and bends under the weight of the pedestrian, so that the ice thorns step out through their holes and provide a non-slip grip.

Claims (2)

Patent claims: 1. Anti-slip heel for street shoes with one at a certain distance from its tread arranged in it, having ice spikes and formed in the heel running surface Through holes for the ice spikes in the event of a corresponding load, characterized in that that the support plate (35) for the ice thorns (19, 20, 21) on the upper wall of a The recess (23) of the heel (1) is arranged, the lower wall of which forms the heel running surface, and that a fork-like intermediate part (29, 30, 36 to 39) is intended to disable the effectiveness of the ice thorns. 2. Shoe heel according to claim 1, characterized in that the support plate (35) has three ice thorns (19, 20, 21) and the intermediate part four, which can be pushed into the cavity (23), by means of a crosspiece (29) has parallel arms (36, 37, 38, 39) connected to the external handle (30), the gaps between them absorb the ice spikes when they are pushed in.
