Lösbare Verbindung zweier teleskopartig ineinander greifender, kraftbelasteter, hohler Stangen zur Längenverstellung der Gesamtkonstruktion Die Erfindung geht aus von einer lösbaren Verbinduna zweier teleskopartig ineinandergreifender, kraftbelasteter, hohler Stangen zur Längenverstellung der Gesamtkonstruktion, wobei die Verbinduna zwischien den hohlen Stangen durch eine Sperre erreicht ist wobei ferner ini Innenraum einer der hohlen Stangen ein ein gebremster Gaskraftspeicher hohen Gasdruckes voraesehen ist.Detachable connection of two telescopically interlocking, force-loaded, hollow rods for adjusting the length of the overall construction The invention is based of a detachable connection between two telescopically interlocking, force-loaded, hollow rods for adjusting the length of the entire construction, with the connection between the hollow rods is reached by a lock, furthermore in the interior one of the hollow rods is provided with a braked gas energy storage device with high gas pressure is.

Es ist bereits eine Einrichtung an einem Operationstisch bekannt, der durch einen Druckkolben in der Höhe verstellbar ist und bei welchem die hohlatisgebildeten Füße als Luftdruckbehälter dienen. Als Druckübertragungsmittel ist eine Flüssigkeit vorgesehen. Der Tisch besteht am Unterteil aus einem schiniedecisernen Windkessel, in den zentrisch ein Zylinder eingeschweißt ist. In dein Zylinder ist ein Kolben yeführt, der unter der Druckwirkung der im Windkessel untergebrachten Druckluft steht. Eine Dämpfung der Kolbenboweaung erfolgt in der Weise, daß die denWindkessel teilweise ausfüllendeFlüssigkeit bei den jeweiligen Kolbenbewegungen im Boden des Windkessels befindliche Mengendurchlaßkanäle durchiströmen inuß Die Arretieruna eriolgt in der Weise daß der Kolben hi seiner unteren Hälfte eine konische Eindrechung hat, auf welcher eine dreiteilige Klembuchse angebracht isi, die ihrerseits durch drei kleine Stahlhebol bewegi wird. Auf diese kleinen Hebel drückt eine stuferföriffig abgesetze Stange, zui deren Aufnahirie der Kolben hohlzylindlrisch ausist. Dadurch, daß die schmiedeeisernen Hohlfüße an dem Windkessel anceschweißt sind, stellt der Luftdruckbehälter eine in die Gesamtkonstruktion einbezogene und mit dicser unlösbar verbundene Baueinheit dar.A device on an operating table is already known, which is adjustable in height by a pressure piston and in which the hollowed-out Feet serve as air pressure vessels. A liquid is used as the pressure transmission medium intended. The table consists of a schiniedeciserne wind chamber on the lower part, A cylinder is welded into the center. There's a piston in your cylinder The under the pressure effect of the compressed air housed in the air chamber stands. A damping of the Kolbenboweaung takes place in such a way that the wind kettle partially filling liquid with the respective piston movements in the bottom of the Flow channels located in the air vessel flow through the arresting device eriolgt in such a way that the piston hi its lower half has a conical indentation has, on which a three-part clamping sleeve is attached, which in turn goes through three small steel levers will move. A stepped handle presses on these little levers Stepped rod, for which the piston is hollow and cylindrical. Through this, that the wrought iron hollow feet are welded to the air chamber, the Air pressure tank included in the overall construction and inseparable with dicser connected structural unit.

Zum Stand der Technik gehört ferner eine teleskopartige Führung für ineinanderverschiebbare, vornehinlich zylindrische Teile, insbesondere für Ständer von Zeichentischen, bei welcher Teleskopständer aus ehnein Windkessessel, einem Verstellkolben. einem Scheiberohr mit Reißbrottkörper und einhem Führungsrollen mit Führdnasrollen besteht.The prior art also includes a telescopic guide for telescoping, primarily cylindrical parts, in particular for stands of drawing tables, with which telescopic stand consists of an air chamber, a Adjusting piston. a Scheiberrohr with shredded bread and a single guide rollers with leadership roles.

Auch hier ist also der Windtfiridkessel eine in die einezogene Baueinheit. Bauemheit. Die der Kolbenverstell bewegung sowie die Arretierunu sind durch ein im Boden des Windkesseleis vorgeschenes, durch einen Fußhebel zu be-Steutierventil bewirkt, welches den nier bieri ndlichen Flüssickeitsduchlaß zwiscben dem und dem den Verdrängerkolbei ent-Zylinder zu öffnen oder zu schließen ge-Bei einem Tisca mit einer eiitiels hydraulische.-Mittel in der Höhe verstellbaren Tischplatte und mit in den Tischbeinen angeordneten, von einer Druckmittelquelle beschickten Zylindern mit Stützkolben ist es bekanntgeworden, die aus einem beispielsweise nit Befestigungslaschen versehenen Zylinder bestehende Druckmittelquelle gegenüber den unterhalb der Tischplatte an den Beinen angeordneten ffliiden lös- und auswechselbar anzuordnen. Jedoch besteht die Konstruktion aus einer Druckmittelquelle als hydraulischein Antriebsteil einerseits und aus Zylindern als hydraulischen Abtriebsteilen andererseits.Here, too, the wind fired boiler is a built-in unit. Bauemheit. The piston adjustment movement and the locking mechanism are through a in the bottom of the air chamber ice, to be controlled by a foot lever causes the beer-free fluid passage between the and the The displacement piston can be opened or closed with a Tisca with a partly hydraulic.-Means adjustable in height and table top with cylinders arranged in the table legs and fed by a pressure medium source with support piston, it has become known that, for example, nit fastening straps provided cylinder existing pressure medium source opposite the one below the table top ffliids arranged on the legs to be detachable and replaceable. However, there is the construction from a pressure medium source as a hydraulic drive part on the one hand and cylinders as hydraulic output parts on the other hand.

Bei Stißdämpfern mit gedämpHer Federung ist es bekanntgeworden, daß der Verdrängyerkolben selbst die Dämpfung der Verstellfiewegung, verrnittelt.In the case of shock absorbers with damped suspension, it has become known that the displacement piston itself dampens the adjustment movement.
