  Gleitsichere Gummisohle. 



   Um Gummisohlen gleitsicher zu machen, wurde bereits vorgeschlagen, der Gummimasse Materialien beizumengen und mitzuvulkanisieren, die beim Gehen die Reibung erhöhen sollen, und dadurch ein Ausgleiten auf dem Boden verhindern. Zu diesem Zwecke wurden der Gummimasse, beispielsweise Beimengungen von tierischen und pflanzlichen Fasern zugesetzt, insbesondere aber Beimengungen von Quarzkörner, Carborundum u. dgl. 



   Alle diese Beimengungen erfüllen aber den angestrebten Zweck nur unvollkommen, da sich diese ortsfremden Bestandteile mit dem Gummi nicht vollkommen binden. Insbesondere trifft dies für die einvulkanisierten Sand-und Quarzkörner zu, die beim Gebrauch aus der Gummimasse leicht herausfallen. 



   Um diese Übelstände zu vermeiden, werden gemäss der vorliegenden Erfindung mit der Gummimasse scharfkantige Körner aus Hartgummi mitvulkanisiert. 



   Beim Vulkanisieren verbinden sieh die scharfkantigen Körner aus Hartgummi vollkommen mit 
 EMI1.1

  Non-skid rubber sole.



   In order to make rubber soles slip-proof, it has already been proposed to add materials to the rubber compound and vulcanize them at the same time, which are intended to increase friction when walking and thereby prevent slipping on the floor. For this purpose, the rubber compound, for example admixtures of animal and vegetable fibers, but especially admixtures of quartz grains, carborundum and the like were added. like



   However, all of these admixtures only incompletely fulfill the intended purpose, since these non-local components do not bind completely with the rubber. This applies in particular to the vulcanized-in sand and quartz grains which easily fall out of the rubber compound during use.



   In order to avoid these inconveniences, according to the present invention, sharp-edged grains of hard rubber are vulcanized along with the rubber compound.



   When vulcanizing, you see the sharp-edged grains of hard rubber connect perfectly with
 EMI1.1
