KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Stoßschienen für Treppenstufen werden vielfach mit Gleitschutzeinlagen versehen, um das Ausgleiten zu verhindern. Die Erfindung betrifft die besondere Anordnung derartiger Gleitschutzeinlagen ; sie besteht darin, daß die runden Gleitschutzeinlagen, die mit Rippen versehen sein können, in einer kreisförmigen Nut drehbar gelagert sind. Infolgedessen werden die abgenutzten, oben liegenden Rippen durch scharfe ersetzt, wenn man die Gleitschutzstäbe um ein geringes Maß verdreht. Wegen dieser Drehbarkeit ist es besonders zweckmäßig, die Riffelung als Schraubengewinde auszubilden.Bumper rails for stairs are often provided with anti-skid inserts to prevent the To prevent slipping. The invention relates to the special arrangement of such anti-skid inserts ; it consists in the fact that the round anti-skid inserts are provided with ribs can be, are rotatably mounted in a circular groove. As a result will be the worn overhead ribs are replaced by sharp ones when the anti-skid bars are used twisted by a small amount. Because of this rotatability, it is particularly useful that Form corrugation as a screw thread.
Wie aus der Fig. ι (Querschnitt) und Fig. 2 (Aufsicht) der Zeichnung ersichtlich ist, ist die Stoßschiene α mit kreisförmigen Längsnuten versehen, in welche die Stäbe b eingeschoben werden. Die Nuten umfassen die Stäbe b bis über einen Halbkreis hinaus. Auf diese Weise werden die Stäbe b zuverlässig in den Nuten der Schiene α festgehalten. Die Stäbe b dienen als Gleitschutz, indem sie aus weicherem Baustoff als die Schiene α hergestellt werden. Beispielsweise kann man die Stoßschiene aus Messing (Delta-Metall), die Stäbe aus Aluminium herstellen.As can be seen from Fig. Ι (cross section) and Fig. 2 (top view) of the drawing, the bumper rail α is provided with circular longitudinal grooves into which the rods b are inserted. The grooves encompass the bars b beyond a semicircle. In this way, the bars b are reliably held in the grooves of the rail α . The bars b serve as anti-skid protection by being made of a softer building material than the rail α . For example, the bumper rail can be made from brass (delta metal) and the rods from aluminum.
Statt die Stäbe b aus einem weicheren Stoff herzustellen als die Schiene a, können sie auch aus einem härteren Stoff, beispielsweise Stahl, hergestellt werden. In diesem Falle wird der obere, aus der Schiene α hervorragende und freiliegende Teil der Stäbe b mit Längs- oder Querrippen versehen, welche das Ausgleiten verhindern. Ist der obere Teil der Einlage abgenutzt, so wird der Stab b in der Nut so weit gedreht, daß ein unabgenutzter Teil nach oben zu liegen kommt. Querrippen können in einfacher Weise dadurch hergestellt werden, daß man den Stab b in seiner ganzen Längsausdehnung mit Gewinde versieht. Ein Teil dieses Gewindes an den Stäben liegt oben frei und bildet den Gleitschutz.Instead of making the rods b from a softer material than the rail a, they can also be made from a harder material, for example steel. In this case, the upper part of the rods b protruding from the rail α and exposed is provided with longitudinal or transverse ribs which prevent slipping. If the upper part of the insert is worn, the rod b is rotated in the groove so far that an unused part comes to rest upwards. Transverse ribs can be produced in a simple manner in that the rod b is provided with a thread over its entire longitudinal extent. Part of this thread on the rods is exposed at the top and forms the anti-slip protection.
