Den Gegenstand der Erfindung bildet ein Stoßfänger für Krücken, Stöcke u. dgl., an welchem außer einem auswechselbaren Gummistollen noch ein auswechselbarer Schnee- oder Eisiuß vorgesehen ist. Dieser Stoßfänger kennzeichnet sich nun dadurch, daß der auswechselbare Schnee- oder Eisfuß unterhalb der Abschlußplatte im Gehäuse in der Weise angebracht ist, daß er eine zur AufnahmeThe subject of the invention is a bumper for crutches, sticks and the like which, in addition to a replaceable rubber stud, also has a replaceable snow or Eisiuss is provided. This bumper is now characterized by the fact that the interchangeable Snow or ice foot is mounted below the end plate in the housing in such a way that it is one for receiving
ίο einer Feder dienende Bohrung besitzt, während sich an den Enden zwei Kugeln befinden, die bei entspannter Feder in die öffnungen des Gehäuses treten und auf diese Weise den Schrieefuß festhalten.ίο has a spring serving hole while there are two balls at the ends which, when the spring is relaxed, slide into the openings of the Step on the housing and hold onto the screeching foot in this way.
Auf der Zeichnung ist ein derartiger Krückenstoßfänger im Längsschnitt in übernatürlicher Größe veranschaulicht.In the drawing, such a crutch bumper is in a longitudinal section in a supernatural view Size illustrated.
Derselbe besteht aus einem zylindrischen Gehäuse a, in welchem eine Führungsbüchse b untergebracht ist, die am oberen Teil durch eine Überwurfmutter c gesichert ist. Im oberen Teil der Führungsbüchse b ist der Stock d untergebracht und mit dieser durch Schrauben oder Nägel verbunden.The same consists of a cylindrical housing a, in which a guide bushing b is housed, which is secured on the upper part by a union nut c. The stick d is housed in the upper part of the guide bushing b and is connected to it by screws or nails.
Im unteren Teil der Büchse b sowie im Gehäuse α befindet sich die Druckfeder e, die unten auf einem Steg oder einer Platte f des Gehäuses aufliegt. Beim Auftreffen des Stoßfängers auf den Boden wird die Feder e durch Abwärtsbewegung der Führungsbüchse b im Gehäuse α zusammengedrückt und dadurch der Stoß in bekannter Weise aufgefangen.In the lower part of the sleeve b and in the housing α there is the compression spring e, which rests on a web or a plate f of the housing below. When the bumper hits the ground, the spring e is compressed by the downward movement of the guide bush b in the housing α and the impact is thereby absorbed in a known manner.
Statt einer Feder e können im Gehäuse a auch andere elastisch wirkende Mittel, z. B.Instead of a spring in the housing can e a, other elastically acting means, for. B.
ein Luftkolben oder ein Glyzerinkolben o. dgl. vorgesehen sein.an air flask or a glycerine flask or the like may be provided.
Der untere Teil des Stoßfängers ist nun so eingerichtet, daß er entweder zur Aufnahme eines Gummistollens g oder eines Schnee- und Eisfußes h dient. Der Gummistollen wird einfach in den unteren Teil des Stoßfängers eingeschoben. Der Schnee- und Eisfuß wird erfindungsgemäß dadurch in leicht auswechselbarer Weise befestigt, daß er mit einer Bohrung i versehen ist, durch welche eine Feder k geht. An den Enden der Feder k befinden sich Kugeln I, .die infolge Spannung der Feder k in Öffnungen m des Gehäuses a eintreten. Wenn man mit den Fingern auf die Kugeln I drückt und die Feder k spannt, so kann man den Schnee- und Eisfuß ohne weiteres herausnehmen bzw. auswechseln.The lower part of the bumper is now set up so that it serves either to receive a rubber stud g or a snow and ice foot h. The rubber stud is simply pushed into the lower part of the bumper. According to the invention, the foot of snow and ice is fastened in an easily replaceable manner in that it is provided with a bore i through which a spring k passes. At the ends of the spring k there are balls I, which enter openings m of the housing a as a result of the tension in the spring k . If you press the balls I with your fingers and tension the spring k , you can easily remove or replace the foot of snow and ice.
