Abstract

A raising device for attachment to hospital beds consists of an oval tube mounted in a support and which can be rotated and locked in any desired position of rotation, on whose upper free end a handgrip is arranged by which the patient can pull himself up. He can swing himself to the edge of the bed by rotation of the oval tube, and as soon as the oval tube is pre-loaded in an axial direction a clutch engages which is built in to a support arranged on the bed-head. The clutch consists of a clutch member connected as an axial extension of the oval tube which has an axial shoulder formed as a cone which engages in a corresponding conical recess of a radially expandable brake shoe whose outer circumference can be pressed in a free-locking fashion against the inner side of a bearing cup which is a bearing for the clutch. Such a clutch enables the rotational position of the oval tube to be locked in any desired angular position.

Description

Die Erfindung betrifft eine Aufrichtevorrichtung für die Anbringung an Krankenhausbetten nach dem Oberbegriff des Patentanspruchs l. Eine derartige Aufrichtevorrichtung ist beispielsweise mit dem Gegenstand der DE-OS 33 27 32O bekannt geworden.The invention relates to an erection device for attachment to hospital beds according to the preamble of claim 1. Such an erecting device has become known, for example, with the subject of DE-OS 33 27 32O.

Derartige Aufrichtevorrichtungen werden insbesondere für frischoperierte oder gehbehinderte Patienten verwendet, wobei der im Bett liegende Patient den dreiecksöfrmigen Haltegriff mit den Händen ergreift und sich daran hochzieht. Das Ovalrohr ist hierbei schwenkbar in der Halterung gelagert, so daß der Patient durch Anhalten am Haltegriff sich über die Drehung des Ovalrohres in der Halterung zum Bettrand schwingen kann. Die gegen Verdrehung sichernde Kupplung soll ein Festlegen des schwenkbaren Ovalrohres in jeder beliebigen Schwenklage in der Halterung gewährleisten. Hierdurch wird verhindert, daß das Ovalrohr zu weit ausschwingt und beispielsweise neben dem Bett stehende Gegenstände beschädigen kann.Raising devices of this type are used in particular for freshly operated or handicapped patients, the patient lying in bed gripping the triangular-shaped handle with his hands and pulling up on it. The oval tube is pivotally mounted in the holder so that the patient can swing over the rotation of the oval tube in the holder to the edge of the bed by stopping at the handle. The coupling, which prevents rotation, is intended to ensure that the pivotable oval tube is fixed in the holder in any pivot position. This prevents the oval tube from swinging out too far and, for example, from damaging objects standing next to the bed.

Bei der bekannten Aufrichtevorrichtung besteht die Kupplung aus einer Klauenkupplung, die entgegen der Federkraft einer Druckfeder einrückbar ist. Ein Nachteil dieser Anordnung ist, daß eine Arretierung dieser Kupplung in beliebigen Zwischenstellungen nicht möglich ist, denn durch die Zahnteilung der ineinander greifenden Klauenkupplung sind nur bestimmte Drehwinkel arretierbar.In the known erecting device, the clutch consists of a dog clutch, which can be engaged against the spring force of a compression spring. A disadvantage of this arrangement is that it is not possible to lock this coupling in any intermediate positions, because only a certain angle of rotation can be locked by the tooth division of the intermeshing claw coupling.

Weiterer Nachteil dieser bekannten Aufrichtevorrichtung ist ferner, daß die Kupplung einem relativ hohen Verschleiß ausgesetzt ist, denn durch den langen Hebelarm vom Haltegriff bis zur Drehachse des Ovalrohres werden hohe Drehmomente auf die Kupplung übertragen, was zu einem baldigen Verschleiß der Klauen führt.Another disadvantage of this known erecting device is that the coupling is exposed to relatively high wear, because of the long lever arm from the handle to the axis of rotation of the Oval tube high torques are transmitted to the coupling, which leads to an early wear of the claws.

Der Erfindung liegt die Aufgabe zugrunde, eine Aufrichtevorrichtung der eingangs genannten Art so weiterzubilden, daß eine Arretierung in beliebigen Verdrehlagen unter Vermeidung einer baldigen Abnutzung der Kupplung möglich ist.The invention has for its object to develop an erecting device of the type mentioned in such a way that it can be locked in any rotational position while avoiding early wear of the coupling.

Zur Lösung der gestellten Aufgabe ist die Erfindung dadurch gekennzeichnet, daß die Kupplung aus einem in axialer Verlängerung des Ovalrohres mit dem Ovalrohr drehfest verbundenen Kupplungsteil besteht, welches einen als Konus ausgebildeten, axialen Ansatz aufweist, der in eine zugeordnete, konische Ausnehmung einer radial spreizbaren Bremsbacke angreift, die mit ihrem Außenumfang kraftschlüssig zur Anlage an der Innenseite eines die Kupplung aufnehmenden Lagertopfes anpressbar ist.
Merkmal der Erfindung ist also, daß das Ovalrohr mit einem als Konus ausgebildeten, axialen Ansatz drehfest verbunden ist und mit diesem Konus in eine zugeordnete konische Ausnehmung einer radial spreizbaren Bremsbacke axial einrückbar ist. Durch das Ineinandergreifen der Keilflächen des Konus und der zugeordneten Keilflächen im Bereich der konischen Ausnehmung werden hohe Drehmomente relativ verschleißfrei aufgenommen und es ist eine Arretierung in jeder beliebigen Verdrehlage möglich.To achieve the object, the invention is characterized in that the coupling consists of a coupling part which is connected in a rotationally fixed manner to the oval tube in the axial extension of the oval tube and which has a conical axial extension which is in an associated conical recess of a radially expandable brake shoe attacks, which can be pressed with its outer circumference non-positively to bear against the inside of a coupling pot receiving the coupling.
A feature of the invention is therefore that the oval tube is connected in a rotationally fixed manner to an axial extension designed as a cone and can be axially engaged with this cone in an associated conical recess of a radially expandable brake shoe. By interlocking the wedge surfaces of the cone and the associated wedge surfaces in the area of the conical recess, high torques are absorbed relatively free of wear and locking in any rotational position is possible.

Hierbei ist nach dem Gegenstand des Anspruches 2 wesentlich, daß der Bremsbacken aus mehreren, segmentförmigen Teilen besteht, die voneinander durch radiale Schlitze getrennt sind, wobei am Außenumfang des Bremsbackens in eine Ringnut eine alle Teile so umspannende Spannfeder angeordnet ist.
Beim Verschieben des als Konus ausgebildeten, axialen Ansatzes, der drehfest mit dem Ovalrohr verbunden ist, in axialer Richtung in die konische Ausnehmung des Bremsbackens hinein werden also die segmentförmigen Teile dieses Bremsbackens radial auswärts gedrückt und zwar entgegen der Kraft der alle Teile umspannenden Spannfeder. Diese segmentförmigen Teile kommen dann mit ihrem Außenumfang zur Anlage an der Innenseite eines unteren Lagertopfes, der an seiner Innenseite mit einer in axialer Richtung verlaufenden Riffelung versehen ist, welche als reibungserhöhende Oberfläche für die daran angepressten Außenflächen der Bremsbacke wirkt.It is essential according to the subject matter of claim 2 that the brake shoe consists of a plurality of segment-shaped parts which are separated from one another by radial slots, with an all-embracing tension spring being arranged in an annular groove on the outer circumference of the brake shoe.
When moving the axial extension, which is designed as a cone and is connected in a rotationally fixed manner to the oval tube, in the axial direction into the Conical recess of the brake shoe into the segment-shaped parts of this brake shoe are pressed radially outward against the force of the tension spring spanning all parts. These segment-shaped parts then come to rest with their outer circumference on the inside of a lower bearing pot, which is provided on the inside with a corrugation running in the axial direction, which acts as a friction-increasing surface for the outer surfaces of the brake shoe pressed against it.

Bevorzugt wird es hierbei, wenn das mit dem Ovalrohr drehfest verbundene Kupplungsteil aus einem Metallteil und die zugeordneten Bremsbacken aus einem Polyamid-Kunststoff bestehen. Hierbei wird eine große Verschleißfreiheit gewährleistet, und Dauerversuche haben gezeigt, daß das erwähnte Material sich durch besonders lange Lebensdauer auszeichnet.It is preferred here if the coupling part, which is connected to the oval tube in a rotationally fixed manner, consists of a metal part and the associated brake shoes consist of a polyamide plastic. A great freedom from wear is guaranteed, and endurance tests have shown that the material mentioned is characterized by a particularly long service life.

Weitere Merkmale der Erfindung sind Gegenstand der übrigen Unteransprüche.Further features of the invention are the subject of the remaining subclaims.

Der Erfindungsgegenstand der vorliegenden Erfindung ergibt sich nicht nur aus dem Gegenstand der einzelnen Patentansprüche, sondern auch aus der Kombination der einzelnen Patentansprüche untereinander. Alle in den Unterlagen offenbarten Angaben und Merkmale, insbesondere die in den Zeichnungen dargestellte räumliche Ausbildung, werden als erfindungswesentlich beansprucht, soweit sie einzeln oder in Kombination gegenüber dem Stand der Technik neu sind.The subject matter of the present invention results not only from the subject matter of the individual patent claims, but also from the combination of the individual patent claims with one another. All of the information and features disclosed in the documents, in particular the spatial configuration shown in the drawings, are claimed to be essential to the invention insofar as they are new to the prior art, individually or in combination.

Das in Figur l gezeigte Krankenhausbett 25 besteht in bekannter Weise aus einem Liegerahmen 28, an dessen vorderem und hinterem Ende jeweils ein Fußgestell 26 und ein Kopfgestell 27 angeordnet sind. Am Kopfgestell 27 ist ein Querholm 32 angebracht, an dem eine obere Einhängevorrichtung 33 für eine Halterung 34 vorgesehen ist. Im Abstand dazu ist im unteren Teil des Kopfgestells 27 eine Führungsplatte 3l vorgesehen, in welchem die Halterung 34 mit einem unteren, axialen Futterrohr 6 (vergl. Fig. 2) eingreift.The hospital bed 25 shown in FIG. 1 consists in a known manner of a bed frame 28, at the front and rear end of which a foot frame 26 and a head frame 27 are arranged. A cross member 32 is attached to the head frame 27, on which an upper suspension device 33 for a holder 34 is provided. At a distance from this, a guide plate 3l is provided in the lower part of the head frame 27, in which the holder 34 engages with a lower, axial casing tube 6 (see FIG. 2).

In der Halterung 34 ist in den Pfeilrichtungen 47 verdrehbar und festlegbar ein Ovalrohr 3O gelagert, an dessen horizontalem Teil 45 ein dreiecksförmiger Handgriff 46 angeordnet ist.An oval tube 30 is rotatably and fixably mounted in the holder 34 in the arrow directions 47, on the horizontal part 45 of which a triangular handle 46 is arranged.

Die gesamte Aufrichtevorrichtung 29 besteht also aus dem Handgriff 46, dem Ovalrohr 3O und der zugeordneten Halterung 34.The entire lifting device 29 thus consists of the handle 46, the oval tube 30 and the associated holder 34.

Die Halterung 34 ist gemäss Figur 2 leicht lösbar mit dem Kopfgestell 27 des Krankenhausbettes 25 dadurch verbunden, indem an der oberen Seite der Halterung 34 eine Verdrehsicherung 8 angeordnet ist, die aus einem umlaufenden Ring besteht, an dem unterhalb einwärts gerichtete, zueinander fluchtende Bolzen 23 angeordnet sind. Diese Bolzen werden in die Einhängevorrichtung 33 eingehängt, wobei gleichzeitig das Futterrohr 6 durch eine zugeordnete Ausnehmung in der unteren Tragplatte 3l eingreift. Auf diese Weise ist die Halterung 34 leicht lösbar am Kopfgestell 27 angeordnet, und es bedarf keiner Umrüstung bereits vorhandener Krankenhausbetten 25, denn die beschriebenen Halterungen 33,3l sind bereits schon an herkömmlichen Krankenhausbetten vorhanden.According to FIG. 2, the holder 34 is easily detachably connected to the head frame 27 of the hospital bed 25 by arranging an anti-rotation device 8 on the upper side of the holder 34, which consists of an encircling ring on which bolts 23 which are directed inwards and below one another are arranged. These bolts are hooked into the suspension device 33, the casing tube 6 simultaneously engaging through an associated recess in the lower support plate 3l. In this way, the holder 34 is arranged in an easily detachable manner on the head frame 27, and there is no need to retrofit existing hospital beds 25, since the holders 33, 31l already described are already present on conventional hospital beds.

Von der Verdrehsicherung 8 abwärts erstreckt sich noch gemäss Figur 2 ein Haltebügel 7, der mit der Außenseite des oberen Lagertopfes l verschweisst ist; dieser trägt die gesamte Anordnung und schont gegen Verdrehung.According to FIG. 2, a holding bracket 7, which is welded to the outside of the upper bearing pot 1, also extends downward from the anti-rotation device 8; this supports the entire arrangement and protects against twisting.

An der Unterseite des Lagertopfes l setzt ein Distanzrohr 2 an, welches mit seinem gegenüberliegenden Ende mit dem unteren Lagertopf 4 verbunden ist. Der untere Lagertopf 4 wird von einem Deckel 3 abgeschlossen und er setzt sich nach unten in einen axialen Lagerwellensitz 5 fort, der schließlich in ein Futterrohr 6 mündet, welches in der vorher beschriebenen Weise lösbar in der Führungsplatte 3l am Kopfgestell 27 des Krankenhausbettes 25 eingesetzt wird.On the underside of the bearing pot 1 there is a spacer tube 2 which is connected at its opposite end to the lower bearing pot 4. The lower bearing pot 4 is closed by a lid 3 and it continues down into an axial bearing shaft seat 5, which finally opens into a casing 6, which is detachable in the manner described above Guide plate 3l is used on the head frame 27 of the hospital bed 25.

Die Figur 3 zeigt, daß das Ovalrohr 3O formschlüssig in eine zugeordnete rechteckförmige Ausnehmung eingesetzt ist, wobei der Außenumfang des Ovalrohres sich in die diagonal einander gegenüberliegenden, abgerundeten Ausnehmungen im oberen Lagertopf l einschmiegen.FIG. 3 shows that the oval tube 30 is inserted in a form-fitting manner in an assigned rectangular recess, the outer circumference of the oval tube nestling into the diagonally opposite, rounded recesses in the upper bearing pot 1.

Der obere Lagertopf besteht gemäss Figur 4,5 und 6 aus einem oberen Schutzdeckel 9, der auf das becherförmige Unterteil dieses Lagertopfes l aufgesetzt ist. Im Unterteil dieses Lagertopfes l ist ein äußerer Lagerring lO vorgesehen, der an seiner Innenseite eine Kugelbüchse ll mit darin angeordneten Kugeln trägt, die an ihrer Innenseite an einem inneren Lagerring l4 abrollen. Der innere Lagerring l4 wird wiederum von einer inneren Ovalfutterbüchse l3 aufgenommen, und die gesamte Anordnung ist unten auf einem Kunststoffring l2 am Boden des becherförmigen Unterteils des Lagertopfes l gelagert.According to FIGS. 4, 5 and 6, the upper bearing pot consists of an upper protective cover 9 which is placed on the cup-shaped lower part of this bearing pot 1. An outer bearing ring 10 is provided in the lower part of this bearing pot 1, which carries on its inside a ball bushing 11 with balls arranged therein, which roll on its inside on an inner bearing ring 14. The inner bearing ring l4 is in turn received by an inner oval chuck l3, and the entire arrangement is supported at the bottom on a plastic ring l2 at the bottom of the cup-shaped lower part of the bearing pot l.

Gemäss Figur 6 ist das Ovalrohr 3O zwar drehfest, jedoch axial verschiebbar, in dem Ovallager l3 gelagert, welches sich mit Rippen 38 an der zugeordneten Innenfläche des inneren Lagerrings l4 abstützt. Das Ovalfutterrohr dreht und bewegt sich frei mit Lagerbuchse radial und axial.According to FIG. 6, the oval tube 30 is rotatably but axially displaceable in the oval bearing l3, which is supported by ribs 38 on the associated inner surface of the inner bearing ring l4. The oval casing tube rotates and moves freely with the bearing bush radially and axially.

Mit der beschriebenen Anordnung können hohe Verkantungskräfte aufgenommen werden, die beim Angreifen eines entsprechenden Patientengwichts am Handgriff 46 auf den oberen Lagertopf l ausgeübt werden.With the arrangement described, high canting forces can be absorbed, which are exerted on the upper bearing pot 1 when a corresponding patient weight is applied to the handle 46.

Die gesamte Lageranordnung ist mit axialem Spiel im oberen Lagertopf l eingebaut. Aus diesem Grunde hat die untere Stirnseite des Schutzdeckels 9 einen axialen Abstand 36 zur oberen Stirnseite des zugeordneten Lageranordnung, die aus dem Lagerring lO, der Kugelbüchse ll , dem inneren Lagerring l4 und der Ovalfutterbüchse l3 besteht.The entire bearing arrangement is with axial play in the upper bearing cup l built in. For this reason, the lower end face of the protective cover 9 has an axial distance 36 to the upper end face of the associated bearing arrangement, which consists of the bearing ring 10, the ball bushing 11, the inner bearing ring 14 and the oval chuck bushing l3.

Ebenso ist die Kugelbüchse ll zwischen der oberen Stirnseite des Lagerrings lO und dessen unterer Stirnseite mit einem axialen Spiel 37 verschiebbar.Likewise, the ball bushing 11 can be displaced with an axial play 37 between the upper end face of the bearing ring 10 and its lower end face.

Gemäss Figur 4,7 und 8 ist im unteren Lagertopf 4 die erfindungsgemässe Kupplung angeordnet.According to FIGS. 4, 7 and 8, the coupling according to the invention is arranged in the lower bearing pot 4.

Der untere Lagertopf 4 besteht aus einem becherförmigen Unterteil 5l, welches über ein Schraubgewinde mit einem zugeordneten Deckel 3 nach oben abgeschlossen wird.The lower bearing pot 4 consists of a cup-shaped lower part 5l, which is closed at the top by a screw thread with an associated cover 3.

Zwischen dem becherförmigen Unterteil des oberen Lagertopfes l und dem Deckel 3 ist das Distanzrohr 2 aufgenommen.The spacer tube 2 is received between the cup-shaped lower part of the upper bearing pot 1 and the cover 3.

Das Ovalrohr 3O, welches sich axial und mit radialem Abstand durch das Distanzrohr 2 erstreckt, ist an seiner Unterseite drehfest mit einem Kupplungsteil l8 aus einem Metallmaterial, z.B. Grauguß, Stahlguß oder dgl. verbunden , wobei die untere Stirnseite des Ovalrohres in eine Ringnut 43 im Kupplungsteil l8 eingreift.The oval tube 30, which extends axially and at a radial distance through the spacer tube 2, is non-rotatably on its underside with a coupling part 18 made of a metal material, e.g. Cast iron, cast steel or the like. Connected, the lower end of the oval tube engages in an annular groove 43 in the coupling part l8.

In Figur 8 ist aus Vereinfachungsgründen diese Ringnut nicht gezeigt, denn es ist ebenso möglich, das Ovalrohr auf den oberen, konisch ausgebildeten, axialen Ansatz des Kupplungsteiles l8 aufzupressen.For reasons of simplification, this annular groove is not shown in FIG. 8, because it is also possible to press the oval tube onto the upper, conically shaped, axial shoulder of the coupling part 18.

Das Kupplungsteil l8 weist einen unteren, als Konus 4O ausgebildeten, axialen Ansatz auf, der äußere Keilflächen 4l aufweist, welche die Kupplungsflächen zu zugeordneten Keilflächen 42 einer konischen Ausnehmung 48 von einer Bremsbacke l6 ausbilden.The coupling part 18 has a lower cone 40 trained, axial approach, which has outer wedge surfaces 4l, which form the coupling surfaces to associated wedge surfaces 42 of a conical recess 48 of a brake shoe l6.

Die Bremsbacke l6 besteht gemäss Figur 4 und 7 aus einem zylinderförmigen Teil, welches in das Unterteil 5l des unteren Lagertopfes 4 eingesetzt ist.According to FIGS. 4 and 7, the brake shoe 16 consists of a cylindrical part which is inserted into the lower part 5l of the lower bearing cup 4.

Im Ausführungsbeispiel nach Figur 7 besteht die Bremsbacke l6 aus vier voneinander durch radiale Schlitze 39 getrennte, segmentförmige Teile 49, die an ihrem Außenumfang mit einer umlaufenden Ringnut versehen ist, in welche eine Spannfeder 2O eingelegt ist. Durch die Spannfeder 2O werden die Teile 49 zusammengehalten und in radialer Richtung nach innen vorgespannt. Alle Teile bilden zusammen eine konische Ausnehmung 48, an deren Innenseite die vorher erwähnten Keilflächen 42 angeordnet sind, die mit den zugeordneten Keilflächen 4l des Kupplungsteiles l8 zusammenwirken.In the exemplary embodiment according to FIG. 7, the brake shoe 16 consists of four segment-shaped parts 49 which are separated from one another by radial slots 39 and which is provided on its outer circumference with a circumferential annular groove into which a tension spring 20 is inserted. The parts 49 are held together by the tension spring 20 and are biased inward in the radial direction. All parts together form a conical recess 48, on the inside of which the aforementioned wedge surfaces 42 are arranged, which interact with the associated wedge surfaces 4l of the coupling part 18.

Sobald nun das Ovalrohr 3O in axialer Richtung in Pfeilrichtung 52 (vergl. Figur l) nach unten bewegt wird, bewegt sich das untere Kupplungsteil l8 entgegen der Kraft einer Druckfeder 2l mit seinen Keilflächen 4l in die Ausnehmung 48 der Bremsbacke l6 hinein.As soon as the oval tube 30 is moved downward in the axial direction in the direction of arrow 52 (see FIG. 1), the lower coupling part 18 moves with its wedge surfaces 4l against the force of a compression spring 2l into the recess 48 of the brake shoe 16.

Die Druckfeder 2l greift hierbei in eine Ausnehmung 52 des Kupplungsteils l8 ein und ist mit dem unteren Ende in einem Lagerwellensitz 5 gelagert, der gleichzeitig zur Halterung einer Lagerwelle l7 dient, auf welche die Druckfeder 2l drehbar und axial verschiebbar gelagert ist. Die Lagerwelle l7 wird im Lagerwellensitz 5 über Gewindestifte 22 drefest gehalten und greift im übrigen noch in das Futterrohr 6 ein.The compression spring 2l engages in a recess 52 of the coupling part l8 and is supported with the lower end in a bearing shaft seat 5, which at the same time serves to hold a bearing shaft l7 on which the compression spring 2l is rotatably and axially displaceably mounted. The bearing shaft 17 is held non-rotatably in the bearing shaft seat 5 by means of setscrews 22 and also engages in the casing 6.

Die Oberseite der Lagerwelle l7 ist in zwei voneinander beabstandeten Gleitlagerbuchsen l9,35 drehbar im Kupplungsteil l8 gelagert.The top of the bearing shaft l7 is in two from each other spaced plain bearing bushes l9,35 rotatably mounted in the coupling part l8.

Mit der axialen Verschiebung des Ovalrohres 3O in Pfeilrichutng 53 gleiten die Keilflächen 4l,42 von Kupplungsteil l8 und Ausnehmung 48 aneinander und die segmentförmigen Teile 49 der Bremsbacke l6 werden radial entgegen der Kraft der Spannfeder 2O nach außen verschoben und treffen sich an der geriffelten Innenfläche des Unterteils 5l des unteren Lagertopfes 4.With the axial displacement of the oval tube 3O in the direction of arrow 53, the wedge surfaces 4l, 42 of the coupling part l8 and recess 48 slide against one another and the segment-shaped parts 49 of the brake shoe l6 are displaced radially outward against the force of the tension spring 2O and meet on the corrugated inner surface of the Lower part 5l of the lower bearing pot 4.

Damit können jetzt hohe Verdrehkräfte arretiert werden, denn durch die großflächige Anlage von einander zugeordneten Keilflächen 4l,42 einerseits und durch die großflächige Anlage des Außenumfangs der segmentförmigen Teile 49 an der geriffelten Innenfläche des Unterteils 5l ergibt sich eine kraftschlüssige Verspannung der genannten Teile im Unterteil 5l.This means that high torsional forces can now be locked, because the large-area contact of wedge surfaces 4l, 42 on the one hand and the large-area contact of the outer circumference of the segment-shaped parts 49 on the corrugated inner surface of the lower part 5l result in a positive locking of the parts mentioned in the lower part 5l .

Wesentlich hierbei ist, daß die Keilflächen 4l,42 so angeschrägt sind, daß es nicht zu einer Selbstklemmung kommen kann. D.h. unter der Kraft der Druckfeder 2l ist die beschriebene Kupplung selbsttätig ausrückbar, wodurch das Ovalrohr 3O in Gegenrichtung zur Pfeilrichtung 53 nach oben geschoben wird und die segmentförmigen Teile 49 der Bremsbacke l6 über die Spannfeder 2O wieder radial einwärts sich bewegen.It is essential here that the wedge surfaces 4l, 42 are chamfered so that self-clamping cannot occur. I.e. Under the force of the compression spring 2l, the clutch described can be disengaged automatically, as a result of which the oval tube 3O is pushed upward in the opposite direction to the arrow direction 53 and the segment-shaped parts 49 of the brake shoe l6 move radially inward again via the tension spring 2O.

Um zu vermeiden, daß beim Ausrücken der Kupplung die Bremsbacken l6 in Gegenrichtung zur eingezeichneten Pfeilrichtung 53 nach oben mitgenommen werden, ist ein Abstreifer l5 vorgesehen, der als umlaufender Ring auf der Bremsbacke l6 aufsitzt und mit seiner Oberseite einen Abstand 5O zur Unterseite des Deckels 3 bildet.In order to avoid that when the clutch is disengaged, the brake shoes l6 are taken upwards in the opposite direction to the arrow direction 53, a stripper l5 is provided, which is seated as a circumferential ring on the brake shoe l6 and with its upper side a distance 50 to the bottom of the cover 3 forms.

Damit kann sich die Bremsbacke l6 nur um das Maß des Abstandes 5O in axialer Richtung im unteren Lagertopf 4 bewegen.This means that the brake shoe l6 can only measure the distance 5O in Move the axial direction in the lower bearing cup 4.

Der untere Lagertopf ist einfach zu öffnen, weil der Deckel 3 mit einem entsprechenden Gewinde 44 auf dem Unterteil 5l aufgeschraubt ist und mittels Kleber fixiert, d.h. drehfest gemacht ist.The lower storage pot is easy to open because the cover 3 is screwed onto the lower part 5l with a corresponding thread 44 and is fixed with adhesive, i.e. is made non-rotatable.

Die vorliegende Erfindung ist nicht auf die Verwendung eines Ovalrohres beschränkt; sie kann genauso beispielsweise mit einem Rundrohr realisiert werden, sofern die entsprechenden Lager rundprofilierte Anpassungen aufweisen. Andere Profilformen, wie Rechteck- oder Viereck-Profile, sind ebenfalls möglich. Die Anordnung ist direkt bei herkömmlichen Bettgalgen einsetzbar und kann ohne Veränderung der bestehenden Vorrichtungen am Bett eingehängt werden.
