Abstract
Description
Die Erfindung betrifft eine Lenkrolle für Apparate, Geräte, Möbel oder dgl., insbesondere fahrbare Stühle, welche mittels eines Gewindebolzens in einem Gewindesackloch einer apparateseitigen Befestigungshülse angeordnet ist.The invention relates to a swivel castor for apparatus, Equipment, Furniture or Like., In particular mobile chairs, which by means of a threaded bolt in a threaded blind hole fastening sleeve on the apparatus side is arranged.
Derartige, druckschriftlich nicht belegbare Lenkrollen nach dem Stand der Technik weisen den Nachteil auf, dass sie bisher nicht mit den bei anderen Lenkrollen üblichen Richtungsfeststellern, vorzugsweise für den Geradeauslauf, versehen werden konnten. Hintergrund ist der Umstand, dass bei Befestigung einer Lenkrolle mittels eines Gewindebolzens an einem Apparat od. dgl. die Endbefestigungsstellung der Lenkrolle zum Apparat od. dgl. nicht bestimmbar ist.Such, not in print Assignable swivel castors according to the prior art have the disadvantage so far that they have not been used with the usual swivel castors Directional locks, preferably for straight running could become. The background is the fact that when fastening a swivel castor by means of a threaded bolt on an apparatus or. Like. The final attachment position of the castor to the apparatus or the like. cannot be determined.
Die bekannten Richtungsfeststeller werden jedoch beim Einsatz andersartiger Befestigungsvorrichtungen, beispielsweise Anschraubplatten, für Lenkrollen eingesetzt, bei denen die Befestigungsstellung der Lenkrolle zum Apparat od. dgl. immer eindeutig bestimmbar ist. Bei diesen Lenkrollen werden Richtungsfeststeller verwendet, die aus einer Rastscheibe bestehen, bei der um 180° versetzt Rastausausnehmungen angeordnet sind, in die zur Richtungsfeststellung ein unterhalb der Rastscheibe angeordneter Raststößel eingreifen kann. Ein derartiger Richtungsfeststeller ist jedoch bei Befestigung der Lenkrolle mittels eines Gewindebolzens am Apparat od. dgl. aufgrund der nicht eindeutig bestimmbaren Endbefestigungsstellung nicht einsetzbar, da hierbei nicht unabhängig von der Ausrichtung der Lenkrolle jeweils eine Rastausnehmung dem Raststößel gegenüberliegt.The well-known directional locks however, when using different types of fastening devices, for example screw-on plates, used for castors, at which the attachment position of the castor to the apparatus or the like. is always clearly determinable. These castors are directional locks used, which consist of a locking disc, with the recessed recesses offset by 180 ° are arranged in the direction determination below the locking disc arranged locking plunger can engage. Such one However, the directional lock is by means of fastening the castor a threaded bolt on the apparatus or the like. Due to the ambiguity definable final fastening position cannot be used, since this not independent from the orientation of the castor one detent each Locking plunger is opposite.
Die Aufgabe der Erfindung besteht nunmehr darin, einen Richtungsfeststeller zu schaffen, der auch bei einer Befestigung der Lenkrolle mittels eines Gewindebolzens an Apparaten, Geräten, Möbeln od. dgl. zuverlässig eine Richtungsfeststellung, vorzugsweise im Geradeauslauf, ermöglicht.The object of the invention is now in creating a directional lock that also when attaching the swivel castor using a threaded bolt on apparatuses, devices, furniture or the like. Reliable a directional determination, preferably in a straight line, enables.
Die Lösung der Aufgabe ergibt sich aus den Merkmalen des Anspruchs 1, insbesondere den Merkmalen des Kennzeichenteils, wonach die Lenkrolle einen Richtungsfeststeller aufweist, dessen beidseitig einer Schwenkebene gegenüberliegend gelagerte Bauteile so ausgebildet sind, dass unabhängig von der Endbefestigungsstellung des Gewindebolzens im Gewindesackloch der Befestigungshülse sowie der Ausrichtung der Lenkrolle zum Apparat od. dgl. bei jeder Betätigung eines zumindest mittelbar damit verbundenen Tritthebels die Schwenkbewegung blockierbar ist.The problem is solved from the features of claim 1, in particular the features of Characteristic part, according to which the castor has a directional lock has, which is mounted on both sides opposite a pivot plane Components are designed so that regardless of the final attachment position of the threaded bolt in the threaded blind hole of the fastening sleeve and the alignment of the castor to the apparatus or the like. Each time a at least indirectly associated kick lever the pivoting movement can be blocked.
Durch die erfindungsgemäße Vorrichtung wird es erstmalig technisch möglich, auch bei einer Befestigung einer Lenkrolle mittels eines Gewindebolzens in einem Gewindesackloch einer apparateseitigen Befestigungshülse eine zuverlässige Richtungsfeststellung zu integrieren. Diese überraschend einfache Lösung kann darüber hinaus technisch sehr unproblematisch in die Konstruktion der Lenkrolle eingefügt werden.Through the device according to the invention it is technically possible for the first time, also when attaching a swivel castor using a threaded bolt in a threaded blind hole of a mounting sleeve on the apparatus side reliable Integrate directional determination. This surprisingly simple solution can about that technically very easy to insert into the construction of the swivel castor.
Bei einer ersten Ausführungsform der Erfindung weist der Richtungsfeststeller eine Rastscheibe mit umlaufender Spitzverzahnung und einer Vielzahl von Eingriffsmöglichkeiten für einen gegenüberliegend angeordneten Raststößel auf, wobei bei jeder Betätigung des Raststößels die Schwenkbewegung des Richtungsfeststellers vorzugsweise in der Geradeauslaufstellung durch Formschluss blockierbar ist. Durch die Schaffung von nahezu lückenlos umlaufend angeordneten Rastausnehmungen ist nun auf einfache Weise bei jeder Ausrichtung der Lenkrolle zum Apparat od. dgl. eine Richtungsfeststellung möglich.In a first embodiment According to the invention, the directional lock has a locking disc all-round serration and a variety of engagement options for one arranged opposite Locking plunger on, with each actuation of the locking plunger Pivotal movement of the directional lock preferably in the straight-ahead position can be blocked by positive locking. By creating almost gapless circumferentially arranged recesses is now simple With each alignment of the castor to the apparatus or the like. A directional determination possible.
Grundsätzlich wäre nach einer weiteren Ausführungsform es jedoch auch denkbar, dass der Richtungsfeststeller eine Bremsscheibe aufweist und dass bei jeder Betätigung eines gegenüberliegend angeordneten Bremsstößels die Schwenkbewegung des Richtungsfeststellers vorzugsweise in der Geradeauslaufstellung durch Reibschluss blockierbar ist. Auch hierbei ist eine zuverlässige Richtungsfeststellung auf einfache Weise verwirklicht, wobei der Herstellungsaufwand geringer ist.Basically would be according to a further embodiment however, it is also conceivable that the directional lock has a brake disc and that with every actuation one arranged opposite Brake plunger Pivotal movement of the directional lock preferably in the straight-ahead position can be blocked by friction. Here, too, is a reliable determination of the direction realized in a simple manner, the manufacturing cost less is.
Die letztgenannte Ausführungsform kann dadurch noch zusätzlich verbessert werden, dass der Bremsstößel zur Bremsscheibe des Richtungsfeststellers weisend mit einem vorzugsweise weichen Bremsbelag versehen ist. Durch den besseren Reibschluss zwischen Bremsstößel und Bremsscheibe erhöht sich hierdurch die Zuverlässigkeit der Richtungsfeststellung.The latter embodiment can additionally be improved that the brake plunger to the brake disc of the directional lock pointing is provided with a preferably soft brake pad. The better frictional connection between the brake tappet and the brake disc increases thereby the reliability the determination of direction.
