Description

Schuli, especially sports shoes

The "price increase" affects a shoe - especially one Sports shoe with an insole and an outsole or heel molded onto the upper leather hard plastic.

The known such shoe designs have the The disadvantage is that, as a result of the use of plastic, the outsole or heel shrinks during hardening (shrinks) and becomes hollow or stands tall «This is undesirable, especially with ice skate boots, because a hollow sole or a hollow heel is a firm and snug fitting holder of the skate on the Sole or heel impaired »

The purpose of the fire is a shoe, especially a sports shoe, of the type mentioned, which is free from these disadvantages "

The shoe, especially sports shoe, with insole and with an outsole or heel made of hard plastic molded onto the upper leather, is in accordance with the!

substantially or by a in the outer sole "the shoulder against the inner sole adjoining ^ previously formed! Pullschicht in _s by the plastic material of the outsole or · paragraph extrusion coated and is made free of shrinkage before the molding of the outsole or of the paragraph, wherein the plastic of the outsole or the heel extends into recesses which are arranged in the fillet layer *

_{By using a lull layer 9} in the outsole or heel, which was previously cut so that it is free of shrinkage, less plastic is sufficient for the outsole or heel injected around it than in a shoe that is not provided with such a! Outsole or »heel has to 3? Olge _? that the mentioned upper part, namely the shrinking and hollowing of the outsole or »the heel, has largely been eliminated»

The plastic _9, which penetrates into the recesses when the outsole or heel is fastened, which were previously arranged in the lull layer, guarantees a tight and firm connection between the filling shaft and the plastic injected around it. This is particularly important if there is see the sports shoe is an ice skate. The retaining hoods of the ice skate only allow a good and firm mounting of the skate on the skate boot if it is ensured that the filling chute and the

enveloping plastic of the outsole "or ·. heel firmly join together *

The recesses in the filling layer can be of a different form "suitable for the desired goal · You can be, _e B» Pet Square, groove-shaped Osdgle © Also they can continue through the insole look across ^ both in the forefoot as also at the heel * This creates a firm connection between the inner sole * and the outer sole (or »heel)

The previously produced and shrink-free filling layer can be made of the same plastic as the molded outsole or the molded heel * However, any other material ^ that is suitable for the desired goal ₉ can be used for the filling shaft «

In order to obtain a good bond between the plastic from the outer sole and the filling chute located therein, the recesses which are present in this extend preferably through the entire thickness of the filling chute Located in the paragraph ^ extend in the form of blind holes, preferably both in the side edge and on the lower edge of this filling sight. This! measure guarantees a firm adhesion of the plastic around the filling shaft of the paragraph

the injection of the plastic for the sale of this Plastic penetrates well into the recesses ^ which are arranged in the side edge of the cover for the paragraph sindj, these recesses are preferably sloping arranged upwards and inwards »

It has been found "that a" particularly advantageous embodiment of the Sehuhs dadur © h is achieved * that the strength of the hopper is approximately equal to half the height or the peripheral edge of molded outsole * of the paragraph is, "Die! Firing unit gedoeh is not limited to this Dimensional ratio limited »

The hiring includes both the embodiment * in the the full view only as a goal plate in the foremost Rope of the shoe is arranged, as well as that execution. ^ in which the filling chute sioh over the full length of the shoe extends below the heel "

Can be used as plastic for the outsole or for the heel 3 Any kind of plastic will be sent for the intended purpose aimed at and suitable for the intended treatment.

The innovation also includes a previously formed or "preformed lüllsehieht for a shoe, in particular sports shoe in which ^ is lüllschicht from shrinking homemade material, for _e B" of plastic and is provided with recesses "
