Description

  

  Vorrichtung an Tischen zur Veränderung der     Tischplattenhöhe.       Die vorliegende Erfindung betrifft eine  Vorrichtung an Tischen zur Veränderung der       Tischplatten,höhe,    welche am Tischgestell  drehbar gelagerte, die     Tisehplatte    tragende  Schrägstützen besitzt, deren Neigung ver  stellbar ist.  



  Auf der beigefügten Zeichnung, die ein       Ausführungebeispiel.    des Erfindungsgegen  standes darstellt, ist       Fig.   <B>1</B> ein Längsschnitt bei gesenkter  Tischplatte,       lig.    2 ein gleicher Längsschnitt bei ge  hobener Tischplatte und       Fig.   <B>3</B> ein Teil des Grundrisses.  



  An der Innenseite, der Stirnbalken der  Zarge<B>1</B> des Tischgestelles sind je an zwei  Winkeln 2     Sohrä--stützen   <B>3</B> schwenkbar ge  lagert. Auf halber Höhe der Schrägstützen  <B>3</B> sind horizontale     Schwenkaelisen    4 für<B>je</B>  zwei Hilfsstützen<B>5</B> angeordnet, deren obere  Enden durch Zapfen<B>6</B> an den Enden von  Traversen,<B>7</B>     angelenkt    sind, welche an der  Unterseite der     Tiseliplatte   <B>8</B> sitzen. In der  Mitte tragen die Mittelteile der Schrägstüt  zen,<B>3 je</B> eine Gewindebuchse<B>9,</B> in welchen  eine Schraubenspindel<B>10</B>     mit    Links- und  Rechtsgewinde angeordnet ist.

   Diese Schrau  benspindel ist in zwei an den Traversen<B>7</B>  festsitzenden Lagern<B>11</B> drehbar, aber nicht,  längsverschiebbar gelagert. Zum Drehen der  Schraubenspindel<B>10</B> kann an das eine oder  andere     Ehde    derselben eine     Handkurbel    12  gesteckt werden.    Durch entsprechendes Drehen der Schrau  benspindel werden die. Gewindebuchsen<B>9</B> re  lativ zueinander verschoben. Dadurch werden  die     SchrIgstützen   <B>3</B> und die     Hilfsstützen   <B>5</B>  und damit auch die     Tiseliplatte    verstellt.

   Da  die Gewinde der Schraubenspindel<B>10</B> selbst  hemmend auf die     Buch6en   <B>9</B> wirken, bleibt  die     Tisehplatte    in der eingestellten Höhen  lage stehen. Die Lager der Schraubenspindel  sind an beiden. Enden der Tischplatte, also  weit voneinander angeordnet. Dadurch wird  eine relativ grosse Stabilität der     Tiechplatte     erreicht.  



  Die     Sehraubenspindel    kann zweiteilig  ausgeführt sein, derart,     dass    auf beiden Tei  len ein Gewinde vorhanden ist und beide  Teile     ineinandergeschoben    und gegeneinander  nicht,     verdrehbar    sind. Die beschriebene     Vor-          rie-lit-un,-,-    kann für Tische verschiedener  Länge verwendet werden. Zum Verstellen der  Schrägstützen könnten auch hydraulische  Mittel verwendet werden. Für die Schräg  stützen und die Hilfsstützen könnten auch  starre Rahmen verwendet     #verden.  



  Device on tables to change the table top height. The present invention relates to a device on tables for changing the table tops, height, which has rotatably mounted on the table frame, the table top supporting inclined supports, the inclination is adjustable ver.



  On the attached drawing, an example of execution. represents the subject matter of the invention, Fig. <B> 1 </B> is a longitudinal section with the table top lowered, lig. 2 shows the same longitudinal section with the table top raised and FIG. 3 shows part of the floor plan.



  On the inside, the front beam of the frame <B> 1 </B> of the table frame, 2 sohrä supports <B> 3 </B> are pivotably mounted on two angles. Halfway up the inclined supports <B> 3 </B> there are horizontal swivel aisles 4 for <B> each </B> two auxiliary supports <B> 5 </B>, the upper ends of which are supported by pins <B> 6 </ B > are hinged to the ends of cross members <B> 7 </B>, which sit on the underside of the table top <B> 8 </B>. In the middle, the middle parts of the diagonal supports, <B> 3 </B> each </B> have a threaded bushing <B> 9 </B> in which a screw spindle <B> 10 </B> is arranged with left and right-hand threads.

   This screw spindle is rotatably mounted in two bearings <B> 11 </B> fixed on the crossbars <B> 7 </B>, but not longitudinally displaceable. To turn the screw spindle 10, a hand crank 12 can be attached to one or the other end of the screw. By turning the screw spindle accordingly, the. Threaded bushings <B> 9 </B> shifted relative to one another. As a result, the angle supports <B> 3 </B> and the auxiliary supports <B> 5 </B> and thus also the table top are adjusted.

   Since the threads of the screw spindle <B> 10 </B> have a self-locking effect on the bushes <B> 9 </B>, the table top remains in the set height. The screw spindle bearings are on both. Ends of the table top, so arranged far from each other. This achieves a relatively high stability of the tissue plate.



  The visual spindle can be designed in two parts, in such a way that a thread is present on both parts and both parts are pushed into one another and cannot be rotated relative to one another. The described Vorrie-lit-un, -, - can be used for tables of different lengths. Hydraulic means could also be used to adjust the props. Rigid frames could also be used for the diagonal supports and the auxiliary supports.
