Description

Die Erfindung bezieht sich auf ein Kranken- oder Pflegebett, mit einem vier Standfüße aufweisenden und einen höhen- und/oder neigungsverstellbaren Bettrahmen tragenden Untergestell, dessen Standfüßen jeweils ein an einer separaten, am Untergestell neben den Standfüßen gelagerten Führung in die Bett-Fahrstellung absenkbares und in die Bett-Standstellung anhebbares Rad zugeordnet ist.The invention relates to a hospital or nursing bed, with a four-footed and a height and / or incline adjustable bed frame supporting base frame, the feet of which are each lowered on a separate, mounted on the base frame next to the feet in the bed driving position and wheel is assigned to the bed standing position.

Für das Fahren und das standsichere Festsetzen von Kranken- oder Pflegebetten ist es bekannt geworden, entweder die Räder höhenverfahrbar vorzusehen oder aber die Standfüße des Untergestelles in sich teleskopartig ausfahrbar auszubilden.For the driving and the stable fixing of hospital or nursing beds, it has become known either to provide the wheels to be height-adjustable or to design the feet of the underframe to be telescopically extendable.

Aufgabe der Erfindung ist es, ein nach der eingangs genannten Art aufgebautes Kranken- oder Pflegebett dahingehend zu verbessern, daß die Höhenverstellung der Räder in einfacher Weise ohne manuelle Betätigungen bequem durchführbar ist und außen am Bett keinerlei Verstell- und Betätigungsmittel störend freiliegen.The object of the invention is to improve a bed or nursing bed constructed according to the type mentioned above in such a way that the height adjustment of the wheels can be carried out in a simple manner without manual actuation and no adjustment and actuating means are exposed to the outside of the bed.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst; die sich daran anschließenden Unteransprüche beinhalten Gestaltungsmerkmale, welche vorteilhafte und förderliche Weiterbildungen der Aufgabenlösung darstellen.This object is achieved by the characterizing features of claim 1; the subsequent subclaims contain design features which represent advantageous and beneficial further developments of the task solution.

Das erfindungsgemäße Kranken- oder Pflegebett ist mit einer einfach aufgebauten, ohne manuelle Handgriffe bequem bedienbaren und nach außen kaum sichtbaren, sowie keine störenden Teile zeigenden Verstellmöglichkeit für die Räder ausgestattet, die auf kurzen Hubwegen über Kniehebel und einen oder zwei motorische Antriebe in die Bett-Standstellung und die Bett-Fahrstellung höhenbewegt werden können.The hospital bed or nursing bed according to the invention is equipped with a simple construction for the wheels, which is easy to operate without manual manipulations and is hardly visible to the outside, and which shows no disruptive parts, and which can be moved into the bed over short strokes using the toggle lever and one or two motor drives Standing position and the bed driving position can be moved in height.

Für diese Radverstellung sind in bevorzugter Weise zwei motorische Antriebe vorgesehen, die jeweils ein in einem Bett-Längenendbereich angeordnetes Kniehebelpaar betätigen, und von diesem Kniehebelpaar wird mindestens eine Druck- und Schubstange das andere im Bett-Längenendbereich angeordnete Kniehebelpaar zwangsläufig mitgenommen, so daß auf Knopfdruck vom Patienten oder vom Pflegepersonal diese Verstellung der Antriebe und aller Räder in die beiden Bettstellungen möglich ist.For this wheel adjustment, two motor drives are preferably provided, each of which actuates a pair of toggle levers arranged in a bed length end region, and from this pair of toggle levers at least one push and push rod is inevitably taken along with the other pair of toggle levers arranged in the bed length end region, so that at the push of a button this adjustment of the drives and all wheels to the two bed positions is possible by the patient or the nursing staff.

Die gesamte Verstellung und der Motor mit den Übertragungsmitteln ist jeweils innerhalb eines Seitenteiles des Bettes angeordnet, somit nach außen kaum sichtbar und ergibt keine nach außen unschön und ungewollt vorstehenden, durch Anstoßen Verletzungen ergebenden und das Gesamtbild störende Bauteile.The entire adjustment and the motor with the transmission means are each arranged within a side part of the bed, so that they are hardly visible from the outside and do not result in unsightly and unintentionally protruding components which result in injuries and disturb the overall picture.

Die gesamte Verstellmechanik mit Motor ist kostengünstig aufgebaut und dauerhaft haltbar ausgeführt.The entire adjustment mechanism with motor is inexpensive and designed to be durable.

Es ist bevorzugt, für ein führungssicheres und störungsfreies Teleskopverschieben der Räder jeder Rad-Teleskopführung ein Kniehebelpaar zuzuordnen und jeweils die beiden in einen gemeinsamen Bett-Längsseitenbereich angeordneten Kniehebelpaare durch ein Druck- und Zugstange und einen Antrieb bewegungsmäßig zu koppeln.It is preferred to assign a pair of toggle levers to each wheel telescopic guide for a safe and trouble-free telescopic displacement of the wheels and to couple the two toggle lever pairs arranged in a common bed longitudinal side area by means of a push and pull rod and a drive.

Es besteht jedoch auch die Möglichkeit, alle vier Kniehebelpaare durch eine gemeinsame Druck- und Zugstange und einen gemeinsamen Antrieb zu betätigen.However, it is also possible to operate all four pairs of toggle levers using a common push and pull rod and a common drive.

Anhand der Zeichnungen wird ein Ausführungsbeispiel der Erfindung nachfolgend näher erläutert. Es zeigt:
