Abstract

Un système de supports comporte des bras et des articulations de liaison conçus de telle manière que chaque bras est formé d'une seule pièce avec les moitiés d'articulation correspondantes. Si la forme du support doit être modifiée, les deux articulations délimitant un bras sont démontées et le bras avec ses moitiés d'articulation est échangé. Ce processus est laborieux et exige une grande diversité des pièces pour modifier le support. Afin de permettre une modification aisée de la forme d'un support, ce dernier possède une articulation (4, 6) constituée de deux moitiés d'articulation (7, 8) mobiles l'une par rapport à l'autre et dont au moins une est reliée à un bras (3, 5). Afin de permettre la variabilité, chaque moitié d'articulation (7, 8) reliée à un bras (3, 5) présente une partie saillante (20, 21) qui peut être raccordée de manière amovible au bras respectif (3, 5) à la manière d'un raccord emmanché. Ce système de support convient particulièrement comme support de plafond pour des unités de soins intensifs, des salles d'opération et autres.A support system has arms and link joints designed such that each arm is formed in one piece with the corresponding joint halves. If the shape of the support has to be changed, the two joints delimiting an arm are removed and the arm with its articulation halves is exchanged. This process is laborious and requires a wide variety of parts to modify the support. In order to allow an easy modification of the shape of a support, the latter has an articulation (4, 6) made up of two articulation halves (7, 8) movable with respect to each other and of which at least one is connected to an arm (3, 5). In order to allow variability, each articulation half (7, 8) connected to an arm (3, 5) has a projecting part (20, 21) which can be removably connected to the respective arm (3, 5) at the way of a press fitting. This support system is particularly suitable as a ceiling support for intensive care units, operating rooms and the like.

StativsystemTripod system
Die Erfindung betrifft ein Stativsystem nach dem Oberbegriff des Patentanspruches 1. Derartige Stative werden insbesondere als Deckenstative für Intensivpflegestationen, Operationssäle u.a. verwendet .The invention relates to a tripod system according to the preamble of claim 1. Such tripods are used in particular as ceiling tripods for intensive care units, operating theaters and others. used.
Aus der DE-GM 86 26 910 ist ein Träger zur schwenkbaren Auf¬ hängung von Steuergeräten bekannt. Eine Gelenkhälfte wird von einem Gehäuse gebildet, das auf einem als Verbindungsrohr aus¬ gebildeten Arm aufgeschoben und dort mittels einer Madenschrau¬ be gesichert wird. Aus der DE-OS 30 34 013 ist ein Stativ be¬ kannt, dessen Arme getrennt von den Gelenkhälften ausgebildet sind. Das Verbinden erfolgt durch Anschrauben der Arme an das Gelenk.From DE-GM 86 26 910 a carrier for the pivotable suspension of control devices is known. A joint half is formed by a housing which is pushed onto an arm designed as a connecting tube and secured there by means of a grub screw. A tripod is known from DE-OS 30 34 013, the arms of which are formed separately from the joint halves. The connection is made by screwing the arms onto the joint.
Aufgabe der Erfindung ist es, ein Stativsystem der eingangs be¬ schriebenen Art zu schaffen, welches so ausgebildet ist, daß eine besonders einfache und gleichzeitig besonders wirksame Verbindung zwischen Armen und Gelenk bei gleichzeitiger einfacher Ausbildung der Gelenke ermöglicht wird.The object of the invention is to provide a tripod system of the type described at the outset, which is designed in such a way that a particularly simple and at the same time particularly effective connection between the arms and the joint is made possible with a simple design of the joints.
Diese Aufgabe wird durch ein Stativsystem mit den Merkmalen des kennzeichnenden Teiles des Patentanspruches 1 gelöst. This object is achieved by a tripod system with the features of the characterizing part of patent claim 1.
Weiterbildungen der Erfindung sind in den Unteransprüchen ge¬ kennzeichnet.Developments of the invention are characterized in the subclaims.
Weitere Merkmale und Zweckmäßigkeiten der Erfindung ergeben sich aus der Beschreibung eines Ausführuπgsbeispieles anhand der Figur.Further features and advantages of the invention result from the description of an exemplary embodiment with reference to the figure.
Die Figur zeigt einen Schnitt durch ein Stativsystem.The figure shows a section through a tripod system.
Das Stativsystem umfaßt ein erstes Gelenk mit einer beispiels¬ weise mit einer Decke verbindbaren Gelenkhälfte 1 und einer mit dieser verbundenen zweiten Gelenkhälfte 2, eine mit der zweiten Gelenkhälfte 2 über einen ersten Arm 3 verbundenes Ge¬ lenk 4, einen mit dem Gelenk 4 verbundenen zweiten Arm 5 und ein mit dem zweiten Arm 5 verbundenes Gelenk 6.The stand system comprises a first joint with a joint half 1 which can be connected to a ceiling, for example, and a second joint half 2 connected to this, a joint 4 connected to the second joint half 2 via a first arm 3 and a second joint connected to the joint 4 Arm 5 and a joint 6 connected to the second arm 5.
Das Gelenk 4 umfaßt eine erste Gelenkhälfte 7 und eine zweite Gelenkhälfte 8. Die erste Gelenkhälfte umfaßt einen schalen ör¬ migen Teil 9 mit einem inneren zylindrischen Abschnitt. Die zweite Gelenkhälfte 8 weist einen ringförmigen Ansatz 10 auf, der in den zylinderförmigen Abschnitt des schalenförmigen Teiles eingreift und mit diesem das eigentliche Lager bildet. Der ringförmige Ansatz 10 wird über ein Drahtwälzlager 11 in dem schalenförmigen Teil lagerförmig getragen. Zu diesem Zweck weist der schalenförmige Teil auf seiner zylindrischen Innen¬ fläche eine sich in Umfangsrichtung erstreckende rechteckför- mige Ausnehmung 12 auf. An der dieser Ausnehmung gegenüber¬ liegenden Stelle weist der ringförmige Ansatz auf seiner Außen¬ fläche eine entsprechende sich in Umfangsrichtung erstreckende rechteckförmige Ausnehmung 13 auf. Der ringförmige Ansatz 10 weist einen ersten ringförmigen Ab¬ schnitt 14 und einen zweiten ringförmigen Abschnitt 15 auf. Die beiden Abschnitte sind mittels Schrauben miteinander lös¬ bar verbunden. Wie aus der Figur ersichtlich ist, ist die Trennebene zwischen den beiden Abschnitten 14 und 15 so ge¬ legt, daß sie durch den Grund der Ausnehmung 13 geht. Dadurch kann beim Montieren des Drahtwälzlagers 11 der zweite ring¬ förmige Abschnitt 15 zunächst abgeschraubt und abgenommen werden, wodurch es möglich ist, die Drahtringe und -kugeln mit zugehörigen Distanzstücken einzusetzen. Anschließend wird der ringförmige Abschnitt 15 in der in der Figur gezeigten Weise aufgesetzt und durch Schrauben mit dem ersten ringför¬ migen Abschnitt 14 fest verbunden.The joint 4 comprises a first joint half 7 and a second joint half 8. The first joint half comprises a shell-shaped part 9 with an inner cylindrical section. The second joint half 8 has an annular extension 10 which engages in the cylindrical section of the shell-shaped part and forms the actual bearing with the latter. The annular extension 10 is supported in the form of a bearing in the shell-shaped part via a wire roller bearing 11. For this purpose, the shell-shaped part has on its cylindrical inner surface a rectangular recess 12 which extends in the circumferential direction. At the point opposite this recess, the annular extension has a corresponding rectangular recess 13 extending in the circumferential direction on its outer surface. The annular extension 10 has a first annular section 14 and a second annular section 15. The two sections are detachably connected to one another by means of screws. As can be seen from the figure, the parting plane between the two sections 14 and 15 is placed so that it passes through the bottom of the recess 13. As a result, when assembling the wire roller bearing 11, the second ring-shaped section 15 can first be unscrewed and removed, which makes it possible to use the wire rings and balls with associated spacers. Then the ring-shaped section 15 is placed in the manner shown in the figure and firmly connected to the first ring-shaped section 14 by screws.
Auf der der ersten Gelenkhälfte zugewandten Seite schließen sich an den zweiten Abschnitt 15 Anschlagringe 16, 17 und ein äußerer Bremsring 18 an. Oberhalb des äußeren Bremsringes ist in der ersten Gelenkhälfte 7 eine Bremseinrichtung 19 vorge¬ sehen und mit dem schalenförmigen Teil 9 fest verbunden. Die Bremseinrichtung weist eine über ein Fluidmittel gesteuerte Membran-betätigte Bremsscheibe auf, die mit dem Bremsring 18 zum Bremsen der Drehbewegung der beiden Gelenkhälften bzw. Arretieren derselben gegeneinander zusammenwirkt.On the side facing the first half of the joint, stop rings 16, 17 and an outer brake ring 18 adjoin the second section 15. Above the outer brake ring, a brake device 19 is provided in the first joint half 7 and is firmly connected to the shell-shaped part 9. The brake device has a diaphragm-actuated brake disk which is controlled by a fluid and which interacts with the brake ring 18 to brake the rotary movement of the two joint halves or to lock them together.
Wie aus der Figur ersichtlich ist, weist jede Gelenkhälfte 7, 8 einen sich in Richtung des damit zu verbindenden Armes 3, 5 erstreckenden Ansatz 20, 21 auf. Die Arme 3, 5 sind rohrförmig ausgebildet. Die Ansätze 20, 21 weisen eine äußere Form und Größe auf, die der Form und Größe des inneren Hohl¬ raumes der rohrförmigen Arme in der Weise entspricht, daß der jeweilige damit zu verbindende rohrför ige Arm 3, 5 nach Art einer Steckverbindung auf den Ansatz 20, 21 über möglichst die gesamte Länge des Ansatzes aufschiebbar ist. Die Länge des An¬ satzes und des das Rohr aufnehmenden Teiles ist so gewählt, daß eine ausreichend steife Verbindung zwischen Arm und Ansatz entsteht.As can be seen from the figure, each joint half 7, 8 has an extension 20, 21 extending in the direction of the arm 3, 5 to be connected to it. The arms 3, 5 are tubular. The lugs 20, 21 have an outer shape and size, which corresponds to the shape and size of the inner cavity of the tubular arms in such a way that the respective tubular arm 3, 5 to be connected to it in the manner of a plug-in connection to the neck 20, 21 can be pushed over the entire length of the attachment if possible. The length of the neck and of the part receiving the pipe is selected so that that there is a sufficiently rigid connection between arm and neck.
Jeder Ansatz weist auf seiner Oberseite eine Ausnehmung 22,Each approach has a recess 22 on its top,
23, auf. Diese erstreckt sich in Richtung der Steckrichtung und weist jeweils in Richtung der Steckrichtung gesehen an den beiden Enden Anschlagwände bildende vertikale Abschnitte23, on. This extends in the direction of the plug-in direction and has vertical sections forming stop walls at both ends when viewed in the direction of the plug-in direction
24, 25 auf. Zur Arretierung der Steckverbindung zwischen dem jeweiligen Arm 3, 5 und dem jeweiligen Ansatz 20, 21 wird in die jeweilige Ausnehmung eine Klemmleiste 26, 27 eingelegt. Die Klemmleiste weist in Steckrichtung gesehen In einem Ab¬ stand voneinander Gewindebohrungen auf, die mit Löchern in dem aufgesteckten Arm deckungsgleich sind. Nach dem Aufstecken des Armes 3 auf den Ansatz 20 werden durch die Löcher Gewinde¬ stifte 28, 29 so in die Klemmleiste geschraubt, daß die Klemm¬ leiste gegen die Innenwand des Armes 3 gepreßt wird und die Gewindestifte mit dem Grund der Ausnehmung in Eingriff sind. Die Gewindestifte sind so lang gewählt, daß sie dabei noch in die Löcher des Armes hineinreichen. So entsteht eine Arretie¬ rung gegen Verschieben des Armes gegen den Ansatz. Die Gewin¬ destifte werden so festgezogen, daß sie eine Klemmverbindung zwischen dem rohrförmigen Arm 3 und dem im Inneren eingesetzten Ansatz bewirken. Die Kraft wird von den Schrauben über die Klemmleisten auf die Armwandung übertragen.24, 25 on. To lock the plug connection between the respective arm 3, 5 and the respective extension 20, 21, a terminal strip 26, 27 is inserted into the respective recess. The terminal strip, viewed in the direction of insertion, has threaded bores at a distance from one another which are congruent with holes in the attached arm. After the arm 3 has been plugged onto the extension 20, threaded holes 28, 29 are screwed into the terminal block through the holes in such a way that the terminal block is pressed against the inner wall of the arm 3 and the threaded pins engage the base of the recess . The set screws are so long that they still extend into the holes in the arm. This creates a lock against shifting the arm against the shoulder. The setscrews are tightened in such a way that they bring about a clamping connection between the tubular arm 3 and the attachment used inside. The force is transferred from the screws to the arm wall via the terminal strips.
Wie aus der Figur ersichtlich ist, sind die einzelnen Gelenke jeweils mit dem gleichen Inneren Aufbau versehen. Die einzel¬ nen mit Armen zu verbindenden Gelenkhälften weisen jeweils gleiche Ansätze auf. Die aufzusteckenden Rohre sind zu diesem Zweck an beiden Enden gleich ausgebildet.As can be seen from the figure, the individual joints are each provided with the same internal structure. The individual joint halves to be connected with arms each have the same approaches. For this purpose, the pipes to be attached are of identical design at both ends.
Die Ansätze der jeweiligen Gelenkhälften und die Gelenkhälften selbst sind ebenfalls hohl ausgebildet, so daß in dem sich er¬ gebenden gesamten Hohlraum Versorgungsleitungen von der Decke durch das Stativ zu der zu tragenden Einrichtung führbar sind. Gewünschtenfalls weist die erste Gelenkhälfte einen Anschlag 30 auf, der mit den Anschlagringen zur Begrenzung der Drehbe¬ wegung zusammenwirkt.The approaches of the respective joint halves and the joint halves themselves are also hollow, so that supply lines from the ceiling are located in the resulting entire cavity can be guided through the tripod to the device to be carried. If desired, the first half of the joint has a stop 30 which interacts with the stop rings to limit the rotational movement.
In dem oben beschriebenen Ausführungsbeispiel ist die jeweili¬ ge Steckverbindung zwischen Arm und Ansatz dadurch gebildet, daß der Ansatz in das Innere des rohrförmigen Armes eingescho¬ ben ist. Es ist in gleicher Weise möglich, eine entsprechende Steckverbindung dadurch zu bewirken, daß die Innenabmessungen des hohlen Ansatzes 20, 21 so bemessen sind, daß sie auf die jeweiligen damit zu verbindenden Arme in der oben beschriebe¬ nen Weise aufschiebbar sind. Die Ausnehmungen 22, 23 sind dann entsprechend in der Wandung des Armes 3 vorzusehen, und die Klemmleisten werden mit den Ansätzen 20, 21 verschraubt.In the exemplary embodiment described above, the respective plug connection between arm and extension is formed in that the extension is pushed into the interior of the tubular arm. In the same way, it is possible to effect a corresponding plug connection in that the internal dimensions of the hollow extension 20, 21 are dimensioned such that they can be pushed onto the respective arms to be connected to them in the manner described above. The recesses 22, 23 are then to be provided accordingly in the wall of the arm 3, and the terminal strips are screwed to the lugs 20, 21.
Mit der oben beschriebenen Ausführungsform ist es möglich, durch beliebige Kombination von verschieden langen oder ver¬ schieden geformten Armen und jeweiligen dazwischen vorzusehen¬ den Gelenken das Stativ in seiner gewünschten Form aufzubauen. With the embodiment described above, it is possible to construct the tripod in its desired shape by any combination of arms of different lengths or different shapes and respective joints provided between them.
