Description

Fahrbarer Krankenstuhl mit Vorrichtung zum Befahren von Treppen Die Erfindung betrifft einen fahrbaren Krankenstuhl, der zwecks Erleichterung des Befahrens von Treppen mit einem gleicharmigen -Kreuz versehen ist, durch dessen Drehung der hintere Teil des Krankenstuhls beim Befahren einer Treppe von Stufe zu Stufe angehoben wird, um hierdurch das Befahren von Treppen so zu erleichtern, daß dasselbe von einer einzigen Bedienungsperson bequem ausgeführt werden kann.Mobile hospital chair with device for climbing stairs The invention relates to a wheeled hospital chair, the purpose of making it easier to drive on of stairs is provided with an equal-armed cross, by rotating the rear part of the chair raised when climbing a staircase from step to step is, in order to facilitate the use of stairs so that the same of can be conveniently carried out by a single operator.

Die Anwendung von derartigen Kreuzen zum Anheben von Fahrzeugen. beim Befahren von Treppen ist an sich bekannt. Die bekannten Vorrichtungen haben aber den Nachteil, daß diese Kreuze sich beim Fahren in der Ebene nicht ausschalten und die Fahrzeuge sich mithin nicht als normale Fahrzeuge, die sich in üblicher Weise auf Rädern fortbewegen, verwenden lassen. Dieser Nachteil tritt besonders da hervor, wo dreirädrige Fahrzeuge in Betracht kommen, bei denen eins der Räder zwecks Befah.rens von Kurven schwenkbar angeordnet ist, wie dies bei fahrbaren Krankenstühlen meist der Fall ist.The use of such crosses for lifting vehicles. at the Driving on stairs is known per se. However, the known devices have the disadvantage that these crosses do not turn off when driving on the plane and The vehicles therefore do not turn out to be normal vehicles that move in the usual way move on wheels, let use. This disadvantage is particularly evident when where three-wheeled vehicles come into consideration, where one of the wheels is used for the purpose of driving is arranged pivotable by curves, as is usually the case with mobile hospital chairs the case is.

Durch den, Erfindungsgegenstand wird dieser Nachteil durch die Ausschaltbarkeit des Kreuzes vermieden.With the subject of the invention, this disadvantage is due to the fact that it can be switched off of the cross avoided.

Die Erfindung ist in der beiliegenden Zeichnung veranschaulicht, und zwar zeigt Abb. i. einen Krankenfahrstuhl mit eingeschaltetem Kreuz, Abb. z denselben Krankenfahrstuhl mit ausgeschaltetem Kreuz und Abb.3 den Krankenfahrstuhl beim Befahren einer Treppe.The invention is illustrated in the accompanying drawing, and although Fig. i shows. an hospital elevator with the cross turned on, Fig. z the same Hospital elevator with the cross turned off and Fig. 3 the hospital elevator when driving a staircase.

Am hinteren Teil des fahrbaren Krankenstuhles ist je ein Kreuz a mit Rollen b links und rechts vom Stuhl angeordnet. Jedes Kreuz sitzt auf einer Achse c, die von zwei Lagerschildern d gehalten werden. Der Antrieb dieser Achsen erfolgt von einer gemeinsamen kleinen Winde e mittels der Kettengetriebe f. Die hintere Schwenkrolleg des Krankenstuhles kann sich so frei zwischen den Kreuzen und deren Lagerung bewegen. Von jedem Kreuz ist ein Doppelarm mit der Welle fest verbunden, während der andere lose auf dieser sitzt, aber in Kreuzstellung sowie in Parallelstellung mit dem anderen Doppelarm durch einen Kuppelstift h fest verbunden werden kann. Der Vorgang beim Befahren von Treppen ist folgender: Der Krankenstuhl wird ganz an die Treppe herangeführt. Die Arme desKreuzes werden aus der Parallelstellung (s. Abb. a) in die Kreuzstellung (s. Abb. i). gebracht und durch die Kuppelstifte in dieser Stellung gegeneinander gesichert. Durch die kleine Winde werden dann die beiden Kreuze zugleich so weit gedreht, -bis der eine Arm senkrecht steht, wobei sich der hintere Teil des Stuhles anhebt und der Schwerpunkt des Stuhles ungefähr, über dem .Stützpunkt der aufliegenden Rolle liegt. Hierauf wird der Stuhl um die aufliegende Rolle so weit nach hinten gekippt und auf ihr zugleich nach vorn geschoben, bis die Vorderräder des . Stuhles auf der zweiten Stufe sind, Durch weiteres Drehen an der Winde mit einer Hand, während die andere den Wagen führt, legen sich die nächsten Arme des Kreuzes auf die erste Stufe auf und heben den hinteren Teil des Wagens an, worauf der Stuhl um eine Stufenbreite nach vorn bei gleichzeitigem Anheben der Vorder--räder geschoben wird. Dieser Vorgang wird nun entsprechend der Anzahl der Stufen wiederholt, bis die Kreuze die letzte Stufe hinter sich haben. Die Doppelarme des Kreuzes werden dann voneinander entkuppelt in Parallelstellung gebracht und in dieser gesichert. In umgekehrter Weise, jedoch bei gleicher Stellung des Stuhles zur Treppe, erfolgt das Befahren von Treppen abwärts.At the rear of the mobile hospital chair there is a cross a with rollers b to the left and right of the chair. Each cross sits on an axis c, which are held by two bearing plates d. These axes are driven by a common small winch e by means of the chain transmission f. The rear swivel castor of the chair can move freely between the crosses and their bearings. One double arm of each cross is firmly connected to the shaft, while the other sits loosely on it, but can be firmly connected to the other double arm in a cross position and in parallel position by a coupling pin h. The process when climbing stairs is as follows: The patient chair is brought right up to the stairs. The arms of the cross move from the parallel position (see Fig. A) into the cross position (see Fig. I). brought and secured against each other by the coupling pins in this position. The two crosses are then turned by the small winch at the same time until one arm is vertical, the rear part of the chair being raised and the center of gravity of the chair being roughly above the supporting point of the roller on top. The chair is then tilted backwards around the castor on top and pushed forward on it at the same time until the front wheels of the. By further turning the winch with one hand while the other is guiding the carriage, the next arms of the cross lie on the first step and lift the back of the carriage, whereupon the chair turns one Step width is pushed forward while lifting the front wheels at the same time. This process is now repeated according to the number of steps until the crosses have passed the last step. The double arms of the cross are then uncoupled from one another, brought into a parallel position and secured in this position. In the opposite way, but with the chair in the same position in relation to the stairs, stairs are descended.

Der große Vorteil dieser Vorrichtung besteht darin, daß damit eine Person in der Lage @ ist, einen Krankenfahrstuhl einschließlich Kranken über Treppen zu befördern, ohne fremde Hilfe in Anspruch zu nehmen.The great advantage of this device is that it is a Person @ is able to use an elevator including sick people using stairs to be transported without using outside help.
