Abstract

The lifting arrangement consists of a column from which an arm (3) can be swung up or down by a motor drive. A seat or support sling is suspended from the end of the arm. The motor drive rotates a screw spindle which raises a tubular extension (5). The upper end of the tubular extension fits in a bracket (12) in whcih it is secured against rotation by a pin (15). The bracket (12) engages at a hinge point with the arm (3). The pin (15) can be removed so that the tubular extension can be rotated by hand to lower the arm. A low friction pad (13) is mounted between the end of the tube (5) and the face of the bracket against whcih it acts.

Description

Die Erfindung betrifft einen Patientenlifter mit H-förmigem Fahrgestell, bei dem die beiden, außenliegenden Fahrbeine an ihren 4 Enden jeweils eine Rolle tragen. Die beiden Fahrbeine sind durch einen außermittig angeordneten Querholm miteinander verbunden.The invention relates to a patient hoist with an H-shaped chassis, in which the two outer legs carry a role at their 4 ends. The two legs are connected by an eccentrically arranged cross member.

Mittig auf diesem Querholm ist eine vertikale Säule angeordnet, an deren oberen Ende ein geknickter Tragarm gelenkig angeschlossen ist, welcher seinerseits am vorderen Ende verschiedene Patientenaufnahmen (z. B. Tuchsitze) einhängen kann.A vertical column is arranged in the middle of this cross member, at the upper end of which a kinked support arm is articulated, which in turn is at the front end various patient admissions (e.g. cloth seats).

Zwischen Säule und Tragarm ist ein Antrieb angeordnet, der die Auf- bzw. Abwärtsbewegung des Tragarmes durch einen ausfahrenden Kolben bewirkt. Der Antrieb hat an seinem oberen und unteren Ende eine U-förmige Konsole, die sich unten an der Säule sowie oben am Tragarm über einen dort befestigten Steg schiebt und mit einem durchgehenden Fixierstift gelenkig verbunden ist. Der ausfahrende Kolben hat Innengewinde, welches auf eine, mit dem Motor fest verbundene Spindel eingedreht ist.A drive is arranged between the column and the support arm, which drives the upward and downward movement the support arm caused by an extending piston. The drive has at its top and lower end of a U-shaped bracket, which is located at the bottom of the column and at the top of the support arm slides over a web attached there and is articulated with a continuous fixing pin connected is. The extending piston has an internal thread, which is fixed on the motor connected spindle is screwed in.

Durch den unten angeschlossenen Motor wird die Spindel in Drehung versetzt und bewegt so den Kolben nach oben, bzw. nach unten. Dadurch wird auch der Tragarm, bzw. der daran hängende Patient nach oben oder unten bewegt, also gehoben oder gesenkt.The spindle is rotated by the motor connected below and thus moves the piston up or down. This also becomes the support arm, or the one on it hanging patient moved up or down, i.e. raised or lowered.

Diese bereits bekannte und bewährte Ausführung hat aber den Nachteil, daß der Tragarm bei einer Störung der Stromversorgung in einer oberen Position stehen bleiben und nicht mehr herunterbewegt werden kann. Der Patient würde in diesem Falle ebenfalls nicht mehr abgesenkt werden können.This already known and proven design has the disadvantage that the support arm in the event of a power failure, stop in an upper position and no longer can be moved down. In this case the patient would also no longer can be lowered.

Der Erfindung liegt daher das Problem zugrunde, die obere, gelenkige, aber nicht drehbare Anlenkung des Kolbens so zu gestalten, daß sie in dem zuvor beschriebenen Notfall auch gedreht werden kann. Dadurch würde man durch manuelles Drehen am Kolben eine Absenkung des Tragarmes und damit des Patienten, bewirken können.The invention is therefore based on the problem of the upper, articulated but not rotatable Articulation of the piston so that they also in the previously described emergency can be rotated. This would make one by manually turning the piston Lowering the arm and thus the patient can cause.

Dieses Problem wird erfindungsgemäß dadurch gelöst, daß die obere Anlenkung des Kolbens an den Tragarm über eine zwischengefügte Kupplungshülse erfolgt, die an ihrem oberen Ende ebenfalls eine U-förmige Konsole trägt und den Kolben von unten her aufnimmt.This problem is solved according to the invention in that the upper articulation of the piston the support arm via an interposed coupling sleeve, which is at its upper end also carries a U-shaped bracket and receives the piston from below.

Kolben und Kupplungshülse sind mittels eines durchgehenden Mitnehmerstiftes fest, also nicht drehbar miteinander verbunden.The piston and clutch sleeve are fixed by means of a continuous driver pin, ie not rotatably connected.

Der Mitnehmerstift ist durch leicht lösbare Federstecker an beiden Enden gesichert und kann ohne Mühe gelöst werden. Nach Entfernen des Mitnehmerstiftes kann der Kolben, z. B. im Uhrzeigersinn manuell gedreht werden und bewegt sich an der Spindel nach unten, ebenso der Tragarm und damit auch der Patient.The driver pin is secured at both ends by easily detachable spring pins and can can be easily solved. After removing the driver pin, the piston, for. B. in Can be turned clockwise manually and moves down on the spindle, as does the Support arm and thus the patient.

Die Erfindung läßt mehrere Ausführungsformen zu. Eine davon ist in der Zeichnung dargestellt und wird nachfolgend beschrieben. In ihr zeigen die:The invention allows several embodiments. One of them is shown in the drawing and is described below. In it show the:

1. Mechanische Notabsenkung für Patientenlifter, dadurch gekennzeichnet, daß eine mit dem Tragarm 3 gelenkig, aber nicht drehbar verbundene Kupplungshülse 12 den Kolben 5 eines Antriebes 4 aufnimmt und mittels eines lösbaren Mitnehmerstiftes 15 gegen Verdrehung fixiert ist.
Nach Entfernen des Sicherungsstiftes 15 ist der Kolben 5 in der Kupplungshülse 12 manuell verdrehbar und kann dadurch über sein Innengewinde an der Spindel 4.2 abgesenkt werden. Die Absenkung bewirkt auch die Absenkung des Tragarmes 3 und damit des an seinem vorderen Ende angehängten Patienten.1. Mechanical emergency lowering for patient lifts, characterized in that a coupling sleeve 12 which is articulated but not rotatably connected to the support arm 3 receives the piston 5 of a drive 4 and is fixed against rotation by means of a releasable driving pin 15 .
After removing the locking pin 15 , the piston 5 can be rotated manually in the coupling sleeve 12 and can thus be lowered via its internal thread on the spindle 4.2 . The lowering also brings about the lowering of the support arm 3 and thus of the patient attached to its front end. 2. Mechanische Notabsenkung nach Anspruch 1, jedoch dadurch gekennzeichnet, daß die U-för­ mige Konsole 17 an ihrer unteren Verlängerung einen Zapfen 17.1 trägt der seinerseits in dem Kolben 5 lagert und mittels Mitnehmerstift 19 gegen Verdrehen gesichert ist. Ein Zwischenlager 18 reduziert die beim Verdrehen des Kolbens 5 entstehende Reibung.
Nach Lösen eines der beiden Federstecker 16 kann der Mitnehmerstift 19 herausgezogen werden, wodurch der Kolben 5 manuell gedreht werden kann. Durch die Verdrehung wird der Tragarm 3 und damit auch der Patient abgesenkt.2. Mechanical emergency lowering according to claim 1, but characterized in that the U-shaped bracket 17 carries at its lower extension a pin 17.1 which in turn is supported in the piston 5 and is secured by means of driving pin 19 against rotation. An intermediate bearing 18 reduces the friction that occurs when the piston 5 is rotated.
After loosening one of the two spring pins 16 , the driver pin 19 can be pulled out, whereby the piston 5 can be rotated manually. The support arm 3 and thus also the patient are lowered by the rotation.
