Abstract
Dargestellt und beschrieben ist eine Einradrolle, insbesondere für Krankenhausbetten, mit einem ein Kopfteil und ein einschenkliges Fußteil aufweisenden Tragteil, dessen Kopfteil zumindest einen Rückenbolzen und dessen Fußteil zumindest eine Nabe für ein Rad aufnimmt, wobei im Tragteil mindestens eine Radfeststelleinrichtung angeordnet ist. Die Aufgabe der Erfindung besteht darin, eine Einradrolle zu schaffen, welche eine Feststellvorrichtung aufweist, deren Bremsparameter auch nach langer Lebensdauer konstant bleiben. Die Lösung dieser Aufgabe ergibt sich daraus, dass die Radfeststelleinrichtung vollständig innerhalb des Tragteils angeordnet ist und formschlüssig auf den Radkörper einwirkt.Shown and described is a unicycle, in particular for hospital beds, having a head part and a einschenkliges foot part having support member, the head part at least one spine and the foot part receives at least one hub for a wheel, wherein in the support member at least one Radfeststelleinrichtung is arranged. The object of the invention is to provide a unicycle which has a locking device whose braking parameters remain constant even after a long service life. The solution to this problem arises from the fact that the Radfeststelleinrichtung is disposed completely within the support member and positively acting on the wheel body.
Description
Die Erfindung betrifft eine Einradrolle, insbesondere für Krankenhausbetten, mit einem ein Kopfteil und ein einschenkliges Fußteil aufweisenden Tragteil, dessen Kopfteil zumindest einen Rückenbolzen und dessen Fußteil zumindest eine Nabe für ein Rad aufnimmt, wobei im Tragteil mindestens eine Radfeststelleinrichtung angeordnet ist.The invention relates to a unicycle, in particular for hospital beds, having a head part and a einschenkliges foot part having support member, the head part at least one spine and the foot at least receives a hub for a wheel, wherein in the support member at least one Radfeststelleinrichtung is arranged.
Aus dem druckschriftlich bekannten Stand der Technik ist eine derartige Einradrolle, bei der die Radfeststelleinrichtung am Tragteil angeordnet ist, beispielsweise aus dem
Ausgehend von diesem Stand der Technik besteht die Aufgabe der Erfindung darin, eine Einradrolle zu schaffen, welche eine Feststellvorrichtung aufweist, deren Bremsparameter auch nach langer Lebensdauer konstant bleiben.Based on this prior art, the object of the invention is to provide a unicycle, which has a locking device whose braking parameters remain constant even after a long service life.
Die Lösung der Aufgabe besteht darin, dass die Radfeststelleinrichtung formschlüssig auf den Radkörper einwirkt und dass die Radfeststelleinrichtung vollständig innerhalb des Tragteils angeordnet ist Die erfindungsgemäße Lösung weist den wesentlichen Vorteil auf, dass durch die formschlüssige Radfeststelleinrichtung auch bei langer Lebensdauer der Einradrolle eine verschleiß- und wartungsfreie Feststelleinrichtung geschaffen wurde, die den zusätzlichen Vorteil aufweist, dass sie auch über die lange Lebensdauer einer Rolle hinweg gegen Verschmutzungen geschützt ist und somit eine hohe Funktionssicherheit aufweist. Neben der hohen Funktionssicherheit erfüllt diese Einradrolle mit innerhalb des Tragteils angeordneter Radfeststelleinrichtung auch hohen hygienischen Ansprüchen, insbesondere im medizinischen Bereich, da sie wesentlich einfacher zu reinigen und zu desinfizieren ist.The solution of the problem is that the Radfeststelleinrichtung acts positively on the wheel body and that the Radfeststelleinrichtung is completely disposed within the support member The solution according to the invention has the significant advantage that the wear-resistant and unobtrusive by the positive Radfeststelleinrichtung even with a long life of the unicycle Locking device was created, which has the additional advantage that it is also protected over the long life of a role away from contamination and thus has a high reliability. In addition to the high level of functional reliability, this unicycle wheel with wheel-locking device arranged inside the supporting part also meets high hygienic requirements, in particular in the medical field, since it is much easier to clean and disinfect.
Bei einer vorteilhaften Ausführungsform der Erfindung ist die Radfeststelleinrichtung in einem zumindest teilweise die Nabe umgebenden Hohlraum des Fußteils angeordnet, der bis auf einen Bewegungsspalt vollständig von dem Radkörper abgedeckt wird, wobei der Hohlraum über einen innenliegenden Funktionsbereich mit dem Hohlraum im Kopfteil mittels der Radfeststelleinrichtung über ein im Funktionsbereich angeordnetes Betätigungsgestänge mit einem Betätigungsexzenter im Kopfteil verbunden ist.In an advantageous embodiment of the invention, the Radfeststelleinrichtung is arranged in an at least partially surrounding the hub cavity of the foot part, which is completely covered except for a movement gap of the wheel body, wherein the cavity via an inner functional area with the cavity in the head part by means of the Radfeststelleinrichtung via a arranged in the functional area actuating linkage is connected to a Betätigungssexzenter in the headboard.
Durch die erfindungsgemäße Schaffung eines im Fußteil des Tragteils um die Radnabe herum angeordneten Hohlraumes, der innenliegend über einen Funktionsbereich mit dem Kopfteil des Tragteils verbunden ist, wird erstmalig die Möglichkeit geschaffen, eine innenliegende, formschlüssige Radfeststelleinrichtung über eine Betätigungseinrichtung im Kopfteil des Tragteils zu steuern. Auch ist die erfindungsgemäße Einradrolle in ein System der Zentralfeststellung beispielsweise an einem Krankenhausbett zu integrieren. Auch ist eine Einzelbetätigung der Einradrolle mittels eines Fußhebels denkbar.The provision according to the invention of a cavity arranged in the foot part of the supporting part around the wheel hub, which is connected internally via a functional area to the head part of the supporting part, for the first time creates the possibility of controlling an internal, positive wheel locking device via an actuating device in the head part of the supporting part. Also, the unicycle roller according to the invention is to be integrated into a system of central detection, for example, on a hospital bed. Also, a single operation of the unicycle by means of a foot lever is conceivable.
Bei einer bevorzugten Ausführungsform der Erfindung ist der vorgenannte Funktionsbereich, also der Verbindungsbereich zwischen dem die Nabe umgebenden Hohlraum im Fußteil und dem Hohlraum im Kopfteil des Tragteils kanalartig ausgebildet, wobei letztendlich auf vorteilhafte Weise in diesem kanalartigen Funktionsbereich ein die Schaltimpulse übertragendes Betätigungsgestänge angeordnet ist.In a preferred embodiment of the invention, the aforesaid functional area, ie the connecting area between the cavity surrounding the hub in the foot part and the cavity in the head part of the supporting part, is channel-like, whereby an actuating linkage transmitting the switching pulses is advantageously arranged in this channel-like functional area.
