Definitions
- the invention relates to a trolley for transporting a variable in length by a lifting support column with a column head and a removable from this table top
- a trolley for transporting a variable in length by a lifting support column with a column head and a removable from this table top comprising an operating table with a chassis and two support bars for supporting the table top, which are at a distance and parallel to each other on the chassis are arranged such that they can be brought into an engagement position with the table top on both sides of the support column.
- Transport trolleys of this type are described, for example, in German patents DE-A-1 158 636 and DE-A-1 196 815.
- the transport carriage In the system described there for transporting the table top of an operating table, the transport carriage is moved up to the operating table in such a way that the support column lies between the two support bars and the support bars reach under the table top. Then the support column of the operating table is lowered. As soon as the table top rests on the support bars of the transport carriage, it can no longer follow the downward movement of the support column, so that it differs from the Tabletop releases. The table top can then be continued on the trolley. The table top is transferred from the transport trolley to the support column in the opposite way.
- the invention has for its object to provide a trolley of the type mentioned easy to operate means that make it possible to use the trolley only for lifting and transporting the table top and on the other hand for transporting the entire operating table.
- At least one support element for supporting the support column of the operating table is arranged on the trolley on both sides of the space between the support bars such that it is in each case between a support position in which it projects into the space between the support bars to reach under a column head-fixed part, and a release position is adjustable, and that two support elements located on either side of the space are connected to one another such that when the one support element is adjusted, the associated other support element in the same position is adjusted.
- the table top can be lifted off the support column in the manner described above and transported without a support column. If, on the other hand, the support elements are adjusted in their support position, in which they engage under a part fixed to the support column, the entire operating table can be transported on the trolley without special locking means being provided between the table top and the support column of the operating table, which are then designed to be so strong should be able to support the weight of the support column.
- the functional connection of the two support elements described above ensures that only one of the elements has to be adjusted, while the further support element coupled to it, which is located on the other side of the transport carriage and thus also on the other side of the operating table, is thereby automatically adjusted as well becomes. This makes operation easier, particularly in cases where there is only a single operator.
- the two support elements can be mechanically coupled to one another in a simple and inexpensive manner in that the support elements are connected to one another by a Bowden cable, the core of which is connected at one end to a support element and at the other end to the trolley and the casing of which is at one end the dolly and his other End is connected to the other support element. If the support element connected to the movable end of the soul is adjusted, the soul bends out because its other end is fixed. This means that the jacket must also follow this deflection. Since its one end is also fixed, it adjusts the other support element connected to its movable end against the direction of adjustment of the first support element. So you get in a very simple way an opposing coupled adjustment of the two support elements.
- the Bowden cable preferably runs through a crossbar connecting the support bars to one another, so that it is neither externally visible nor in any other way disturbing and is itself secured against possible damage.
- the support elements are each designed in the form of a folding lever, which is each pivotably mounted on a stand of the transport carriage which supports a support bar, the soul and the jacket of the Bowden cable with their respective movable ends being at a distance from the pivot axis of the respective folding lever attack on this.
- the transport carriage shown in FIGS. 1 and 2 comprises a chassis, generally designated 10, with longitudinal bars 12 which are connected to one another by at least one transverse bar 14 in the region of one of their longitudinal ends and on which wheels 16 are mounted. It can be seen in FIG. 1 that the chassis is open on one side, so that the transport carriage can be approached to a support column of an operating table 20 (FIG. 2) in such a way that the two longitudinal spars 12 lie on both sides of the support column 18.
- a horizontal support beam 24 is arranged on the longitudinal beams 12 via a vertical stand 22, which runs essentially parallel to the respective longitudinal spar 12.
- the construction is selected so that in the position of the transport carriage shown in FIG. 1 relative to the support column 18 of the operating table 20, the support bars 24 can reach under the table top 26 of the operating table. It should be emphasized, however, that the support bars do not really have to reach under the table top, but that there must only be the possibility that the support bars can engage with mounting elements fastened to the table top.
- a folding lever 28 is pivotally mounted near the support beam 24 in such a way that it can be pivoted between a release position which can be seen in FIG. 3 and a support position which can be seen in FIGS. 2 and 4, in which it has a support element 30 in the intermediate space protrudes between the support bars 24 and can reach under the column head 32 of the support column 18.
- the support column 18 is lowered by its built-in lifting device, the table top is taken over by the transport carriage.
- the support column 18 detaches from the table top.
- the transport trolley can be moved away with the table top.
- the folding levers 28 are pivoted into the position shown in FIG. 4, in which they reach under the column head 32. If, starting from the position shown in FIG. 2, the lifting device of the support column 18 is actuated in the sense of lowering the support column, then instead of lowering the column head and the Table top now the column base is raised because the column head rests on the support elements 30 which are rigid in height. Now the entire operating table can be moved.
- FIG. 5 shows how the two support elements 30 can be adjusted in a convenient manner with the folding levers 28, it being sufficient to actuate one of the folding levers 28 in each case.
- the other folding lever then performs the opposite movement.
- the two folding levers are connected by a Bowden cable, generally designated 34.
- the core 36 of the Bowden cable is fastened to an element 38 fixed to the trolley.
- the associated end of the jacket 40 of the Bowden cable 34 is connected to the folding lever 28 at a point 44 remote from the pivot axis 42 of the folding lever 28.
- the core 36 of the Bowden cable 34 is connected to the folding lever 28 at a point 46 remote from the pivot axis 42, while the associated end of the jacket 40 of the Bowden cable is fastened to a point 48 fixed to the trolley.
- the folding lever is designed as a fork-shaped part with two legs 52 and 54, in which the bearing bores 56 for receiving the pivot shaft 52 are located.
- the two legs 52, 54 are connected to one another by a central web 58, which strikes the stand 22 when the folding lever 28 is pivoted into its resting position and thus simultaneously limits the pivoting path of the respective folding lever and defines the resting position of the folding lever.
- an inclined surface 60 formed at the free end of the support element 30 is directed horizontally, so that a solid support for the support column is obtained.

Description
Die Erfindung betrifft einen Transportwagen zum Transport eines eine in ihrer Länge durch eine Hubeinrichtung veränderliche Stützsäule mit einem Säulenkopf und eine von dieser abnehmbare Tischplatte umfassenden Operationstisches mit einem Fahrgestell und zwei zur Auflage der Tischplatte bestimmten Tragholmen, die in einem Abstand und parallel zueinander an dem Fahrgestell derart angeordnet sind, daß sie beiderseits der Stützsäule in eine Eingriffsstellung mit der Tischplatte bringbar sind.The invention relates to a trolley for transporting a variable in length by a lifting support column with a column head and a removable from this table top comprising an operating table with a chassis and two support bars for supporting the table top, which are at a distance and parallel to each other on the chassis are arranged such that they can be brought into an engagement position with the table top on both sides of the support column.
Transportwagen dieser Art sind beispielsweise in den deutschen Patentschriften DE-A-1 158 636 und DE-A-1 196 815 beschrieben. Bei dem dort beschriebenen System zum Transport der Tischplatte eines Operationstisches wird der Transportwagen so an den Operationstisch herangefahren, daß die Stützsäule zwischen den beiden Tragholmen liegt und die Tragholme die Tischplatte untergreifen. Dann wird die Stützsäule des Operationstisches abgesenkt. Sowie die Tischplatte auf den Tragholmen des Transportwagens aufliegt, kann sie der Abwärtsbewegung der Stützsäule nicht mehr folgen, so daß diese sich von der Tischplatte löst. Anschließend kann die Tischplatte auf dem Transportwagen fortgefahren werden. Die Übergabe der Tischplatte vom Transportwagen auf die Stützsäule erfolgt in der umgekehrten Weise.Transport trolleys of this type are described, for example, in German patents DE-A-1 158 636 and DE-A-1 196 815. In the system described there for transporting the table top of an operating table, the transport carriage is moved up to the operating table in such a way that the support column lies between the two support bars and the support bars reach under the table top. Then the support column of the operating table is lowered. As soon as the table top rests on the support bars of the transport carriage, it can no longer follow the downward movement of the support column, so that it differs from the Tabletop releases. The table top can then be continued on the trolley. The table top is transferred from the transport trolley to the support column in the opposite way.
Aus der japanischen Patentschrift JP-B2-62-55422 ist es ferner bekannt, einen Operationstisch als ganzes zu transportieren, indem die Tragholme starr mit dem Säulenkopf verbundene Teile untergreifen können. Wird in diesem Falle die Hubeinrichtung des Operationstisches innerhalb der Stützsäule im Sinne eines Absenkens der Tischplatte betätigt, so kann nach dem Aufliegen der mit dem Säulenkopf starr verbundenen Teile auf den Trageholmen des Transportwagens die Stützsäule nicht weiter abgesenkt werden. Stattdessen wird der Säulenfuß angehoben. Anschließend kann der Operationstisch als ganzes transportiert werden. Dieses System ist jedoch anwendbar bei einem Transportwagen, der dazu bestimmt ist, die Tischplatte und nicht mit dem Säulenkopf verbundene Teile zu untergreifen, sofern nicht eigene Verriegelungsmittel vorgesehen sind, welche eine Verbindung zwischen Tischplatte und Stützsäule auch dann gewährleisten, wenn der Operationstisch nur mit der Tischplatte auf dem Transportwagen aufliegt.From Japanese patent specification JP-B2-62-55422 it is also known to transport an operating table as a whole by allowing the support bars to reach under parts rigidly connected to the column head. If in this case the lifting device of the operating table is actuated within the support column in the sense of lowering the table top, the support column cannot be lowered any further after the parts rigidly connected to the column head rest on the carrying spars of the transport carriage. Instead, the column base is raised. The operating table can then be transported as a whole. However, this system is applicable to a transport trolley which is intended to grip under the table top and parts not connected to the column head, unless own locking means are provided, which ensure a connection between the table top and the support column even if the operating table only with the Table top rests on the transport trolley.
Der Erfindung liegt die Aufgabe zugrunde, an einem Transportwagen der eingangs genannten Art einfach zu betätigende Mittel vorzusehen, die es ermöglichen, einerseits den Transportwagen nur zum Abheben und Transport der Tischplatte und andererseits aber auch zum Transport des gesamten Operationstisches verwenden zu können.The invention has for its object to provide a trolley of the type mentioned easy to operate means that make it possible to use the trolley only for lifting and transporting the table top and on the other hand for transporting the entire operating table.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an dem Transportwagen beiderseits des Zwischenraumes zwischen den Tragholmen mindestens je ein Auflageelement zur Abstützung der Stützsäule des Operationstisches derart angeordnet ist, daß es jeweils zwischen einer Auflagestellung, in der es zum Untergreifen eines Säulenkopffesten Teiles in den Zwischenraum zwischen den Tragholmen hineinragt, und einer Freigabestellung verstellbar ist, und daß je zwei beiderseits des Zwischenraumes gelegene Auflageelemente derart miteinander verbunden sind, daß beim Verstellen des einen Auflageelementes das zugehörige andere Auflageelement in dieselbe Stellung verstellt wird.This object is achieved in that at least one support element for supporting the support column of the operating table is arranged on the trolley on both sides of the space between the support bars such that it is in each case between a support position in which it projects into the space between the support bars to reach under a column head-fixed part, and a release position is adjustable, and that two support elements located on either side of the space are connected to one another such that when the one support element is adjusted, the associated other support element in the same position is adjusted.
Befinden sich die Auflageelemente in der Freigabestellung, dann kann in der oben beschriebenen Weise die Tischplatte von der Stützsäule abgehoben und ohne Stützsäule transportiert werden. Werden dagegen die Auflageelemente in ihrer Auflagestellung verstellt, in der sie ein stützsäulenfestes Teil untergreifen, so kann der gesamte Operationstisch auf dem Transportwagen transportiert werden, ohne daß hierzu spezielle Verriegelungsmittel zwischen der Tischplatte und der Stützsäule des Operationstisches vorgesehen sind, die dann so stark ausgebildet sein müßten, daß sie das Gewicht der Stützsäule tragen können. Zudem gewährleistet die oben beschriebene funktionelle Verbindung der beiden Auflageelemente, daß nur eines der Elemente verstellt werden muß, während das mit diesem gekoppelte weitere Auflageelement, das sich auf der anderen Seite des Transportwagens und damit auch auf der anderen Seite des Operationstisches befindet, dadurch automatisch mitverstellt wird. Dies erleichtert die Bedienung insbesondere in den Fällen, wo nur eine einzelne Bedienungsperson vorhanden ist.If the support elements are in the release position, the table top can be lifted off the support column in the manner described above and transported without a support column. If, on the other hand, the support elements are adjusted in their support position, in which they engage under a part fixed to the support column, the entire operating table can be transported on the trolley without special locking means being provided between the table top and the support column of the operating table, which are then designed to be so strong should be able to support the weight of the support column. In addition, the functional connection of the two support elements described above ensures that only one of the elements has to be adjusted, while the further support element coupled to it, which is located on the other side of the transport carriage and thus also on the other side of the operating table, is thereby automatically adjusted as well becomes. This makes operation easier, particularly in cases where there is only a single operator.
Die beiden Auflageelemente lassen sich in einfacher und preiswerter Weise mechanisch dadurch miteinander koppeln, daß die Auflageelemente durch einen Bowdenzug miteinander verbunden sind, dessen Seele an ihrem einen Ende mit einem Auflageelement und an ihrem anderen Ende mit dem Transportwagen und dessen Mantel an seinem einen Ende mit dem Transportwagen und an seinem anderen Ende mit dem anderen Auflageelement verbunden ist. Wird das mit dem beweglichen Ende der Seele verbundene eine Auflageelement verstellt, so biegt sich die Seele aus, da ihr anderes Ende fest liegt. Dies führt dazu, daß auch der Mantel dieser Ausbiegung folgen muß. Da sein eines Ende ebenfalls fest liegt, verstellt er das mit seinem beweglichen Ende verbundene andere Auflageelement entgegen der Verstellrichtung des ersten Auflageelementes. So erhält man in sehr einfacher Weise eine gegenläufige gekoppelte Verstellung der beiden Auflageelemente. Vorzugsweise verläuft der Bowdenzug durch einen die Tragholme miteinander verbindenden Querholm, so daß er äußerlich weder sichtbar noch in anderer Weise störend ist und auch selbst gegen eine mögliche Beschädigung gesichert ist.The two support elements can be mechanically coupled to one another in a simple and inexpensive manner in that the support elements are connected to one another by a Bowden cable, the core of which is connected at one end to a support element and at the other end to the trolley and the casing of which is at one end the dolly and his other End is connected to the other support element. If the support element connected to the movable end of the soul is adjusted, the soul bends out because its other end is fixed. This means that the jacket must also follow this deflection. Since its one end is also fixed, it adjusts the other support element connected to its movable end against the direction of adjustment of the first support element. So you get in a very simple way an opposing coupled adjustment of the two support elements. The Bowden cable preferably runs through a crossbar connecting the support bars to one another, so that it is neither externally visible nor in any other way disturbing and is itself secured against possible damage.
Gemäß einer bevorzugten Ausführungsform sind die Auflageelemente jeweils in Form eines Klapphebels ausgeführt, der jeweils an einem einen Tragholm abstützenden Ständer des Transportwagens schwenkbar gelagert ist, wobei die Seele und der Mantel des Bowdenzuges mit ihrem jeweiligen beweglichen Ende in einem Abstand von der Schwenkachse des jeweiligen Klapphebels an diesem angreifen. Diese Lösung läßt sich auf einfache Weise verwirklichen und bietet dennoch die Möglichkeit einer stabilen Auflage und einer zuverlässigen Verstellbarkeit.According to a preferred embodiment, the support elements are each designed in the form of a folding lever, which is each pivotably mounted on a stand of the transport carriage which supports a support bar, the soul and the jacket of the Bowden cable with their respective movable ends being at a distance from the pivot axis of the respective folding lever attack on this. This solution can be implemented in a simple manner and still offers the possibility of a stable support and reliable adjustability.

Der in den Figuren 1 und 2 dargestellte Transportwagen umfaßt ein allgemein mit 10 bezeichnetes Fahrgestell mit Längsholmen 12, die durch mindestens einen Querholm 14 im Bereich eines ihrer Längsenden miteinander verbunden sind und an denen Räder 16 gelagert sind. Man erkennt in Figur 1, daß das Fahrgestell auf der einen Seite offen ist, so daß der Transportwagen derart an eine Stützsäule eines Operationstisches 20 (Figur 2) heranfahrbar ist, daß die beiden Längsholme 12 beiderseits der Stützsäule 18 liegen.The transport carriage shown in FIGS. 1 and 2 comprises a chassis, generally designated 10, with
Auf den Längsholmen 12 ist jeweils über einen vertikalen Ständer 22 ein horizontaler Tragholm 24 angeordnet, der im wesentlichen parallel zu dem jeweiligen Längsholm 12 verläuft. Die Konstruktion ist so gewählt, daß in der in Figur 1 dargestellten Stellung des Transportwagens relativ zur Stützsäule 18 des Operationstisches 20 die Tragholme 24 die Tischplatte 26 des Operationstisches untergreifen können. Dabei ist jedoch zu betonen, daß die Tragholme nicht wirklich bildlich unter die Tischplatte greifen müssen, sondern daß lediglich die Möglichkeit bestehen muß, daß die Tragholme mit an der Tischplatte befestigten Halterungselementen in Eingriff treten können.A
An den Ständern 22 ist jeweils nahe dem Tragholm 24 ein Klapphebel 28 derart schwenkbar gelagert, daß er zwischen einer in der Figur 3 erkennbaren Freigabestellung und einer in den Figuren 2 und 4 erkennbaren Auflagestellung verschwenkbar ist, in der er mit einem Auflageelement 30 in den Zwischenraum zwischen den Tragholmen 24 hineinragt und den Säulenkopf 32 der Stützsäule 18 untergreifen kann.On the
Wird ausgehend von der in Figur 2 dargestellten Stellung die Stützsäule 18 durch ihre eingebaute Hubeinrichtung abgesenkt, so wird die Tischplatte von dem Transportwagen übernommen. Die Stützsäule 18 löst sich von der Tischplatte. Der Transportwagen kann mit der Tischplatte weggefahren werden.If, starting from the position shown in FIG. 2, the
Will man dagegen den gesamten Operationstisch einschließlich der Stützsäule 18 transportieren, so werden die Klapphebel 28 in die in der Figur 4 dargestellte Stellung verschwenkt, in der sie den Säulenkopf 32 untergreifen. Wird nun ausgehend von der in der Figur 2 dargestellten Stellung die Hubeinrichtung der Stützsäule 18 im Sinne eines Absenkens der Stützsäule betätigt, so wird statt des Absenkens des Säulenkopfes und der Tischplatte nun der Säulenfuß angehoben, da der Säulenkopf auf den in der Höhe starren Auflageelementen 30 aufliegt. Nun kann der gesamte Operationstisch bewegt werden.If, on the other hand, you want to transport the entire operating table including the
Die Figur 5 zeigt, wie die beiden Auflageelemente 30 mit den Klapphebeln 28 auf bequeme Weise verstellt werden können, wobei es jeweils genügt, einen der Klapphebel 28 zu betätigen. Der andere Klapphebel führt dann die hierzu gegenläufige Bewegung aus. Hierzu sind die beiden Klapphebel durch einen allgemein mit 34 bezeichneten Bowdenzug verbunden. An dem in der Figur 5 linken Klapphebel 28 ist die Seele 36 des Bowdenzugs an einem transportwagenfesten Element 38 befestigt. Das zugehörige Ende des Mantels 40 des Bowdenzuges 34 ist an einer von der Schwenkachse 42 des Klapphebels 28 entfernt gelegenen Stelle 44 mit dem Klapphebel 28 verbunden. Bei dem in der Figur 5 rechts dargestellten Klapphebel ist dagegen die Seele 36 des Bowdenzuges 34 an einer von der Schwenkachse 42 entfernt gelegenen Stelle 46 mit dem Klapphebel 28 verbunden, während das zugehörige Ende des Mantels 40 des Bowdenzuges an einer transportwagenfesten Stelle 48 befestigt ist.FIG. 5 shows how the two
Wird der in der Figur 5 rechts dargestellte Klapphebel in Richtung des Pfeiles A im Gegenuhrzeigersinn verstellt, so beult sich die Seele 36 in der durch eine gestrichelte Linie 50 wiedergegebenen Weise aus, da ihr linkes Ende nicht ausweichen kann. Da der Mantel 40 der Bewegung der Seele 36 folgen muß, andererseits mit seinem rechten Ende ebenfalls am Transportwagen fest liegt, wird hierdurch zwangsweise der linke Klapphebel 28 im Uhrzeigersinn in Richtung des Pfeiles B verstellt. In der gleichen Weise kann auch die Verstellung beider Klapphebel durch eine manuelles Verschwenken nur des linken Klapphebels erreicht werden. Diese Kopplung der beiden Klapphebel erleichtert die Bedienung des Transportwagens durch eine einzelne Bedienungsperson erheblich, da die Bedienungsperson nicht erst um den Operationstisch herumlaufen laufen muß, um die Klapphebel auf beiden Seiten zu betätigen.If the folding lever shown on the right in FIG. 5 is adjusted in the direction of arrow A counterclockwise, the core 36 bulges in the manner represented by a
Wie man in den Figuren 6 und 7 erkennt, ist der Klapphebel als gabelförmiges Teil ausgebildet mit zwei Schenkeln 52 und 54, in denen sich die Lagerbohrungen 56 zur Aufnahme der Schwenkwelle 52 befinden. Die beiden Schenkel 52, 54 sind durch einen Mittelsteg 58 miteinander verbunden, der beim Verschwenken des Klapphebels 28 in seine Auflagestellung an dem Ständer 22 anschlägt und damit gleichzeitig den Schwenkweg des jeweiligen Klapphebels begrenzt und die Auflagestellung des Klapphebels festlegt. In dieser Auflagestellung ist eine am freien Ende des Auflageelementes 30 ausgebildete Schrägfläche 60 horizontal gerichtet, so daß man eine solide Auflage für die Stützsäule erhält.As can be seen in Figures 6 and 7, the folding lever is designed as a fork-shaped part with two
An dem Schenkel 54 des Klapphebels ist ein nach innen ragender Fortsatz 62 ausgebildet, an dem die Seele bzw. der Mantel des Bowdenzuges 34 befestigt werden können. Der andere Klapphebel ist spiegelsymmetrisch zu dem hier beschriebenen Klapphebel ausgebildet.On the
