Abstract
Description
Die vorliegende Erfindung betrifft eine Scherenhubvorrichtung für eine Liege oder einen Tisch mit den Merkmalen des Oberbegriffs des Anspruchs 1.The present invention relates to a scissor lift device for a couch or a table with the characteristics of the generic term of Claim 1.
Scherenhubtische, bei denen parallel
angeordnete Scheren, bestehend aus gekreuzten Scherenarmpaaren zur
Höhenverstellung
von Hebetischen verwendet werden, sind bekannt (beispielsweise
Aufgabe der vorliegenden Erfindung ist es, eine Scherenhubvorrichtung für eine Liege oder einen Tisch zu schaffen, die es mit einfachen Mitteln ermöglicht, eine größere Hubhöhe zu erzielen und die einen sanften und schnellen Hebevorgang ermöglicht. Insbesondere ist es eine Aufgabe der vorliegenden Erfindung, eine Scherenhubvorrichtung zu schaffen, die über einen großen Hubweg eine starke exzentrische Belastung aufnehmen kann und die besonders kompakt baut.Object of the present invention is a scissor lift for a bed or table to create, which makes it possible to achieve a greater lifting height with simple means and which enables a gentle and quick lifting process. In particular, it is an object of the present invention to: To create scissor lifters that have a long stroke can take a strong eccentric load and especially compact.
Diese Aufgabe wird mit den Merkmalen des Oberbegriffs des Anspruchs 1 gelöst. Fortbildungen und vorteilhafte Ausführungen der Erfindung sind in den weiteren Ansprüchen umfasst Erfindungsgemäß ist eine Scherenhubvorrichtung für eine Liege oder einen Tisch, wobei die Scherenhubvorrichtung zwischen einem unteren Rahmen und einem Träger für die Liege oder den Tisch angeordnet ist, wobei die Scherenhubvorrichtung aus gekreuzten Scherarmen besteht die jeweils vertikal und parallel an zwei Seiten des Trägers, bzw. Rahmens angeordnet sind, wobei die Scherarme in der Mitte gelenkig miteinander verbunden sind und wobei ein Spindeltrieb direkt oder indirekt auf wenigstens ein Ende eines Scherenarms wirkt, so dass die Scherenarme zwischen einer ausgefahrenen und einem zusammengelegten Position bewegbar sind und wobei jeweils ein oberes oder unteres Ende eines Scherenarmpaars fest mit dem Rahmen oder dem Träger verbunden ist und das jeweils andere Ende verschiebbar in oder an dem Rahmen oder Träger angeordnet ist, dadurch gekennzeichnet, dass jeweils zwei Scherenarmpaare übereinander angeordnet sind, wobei die unteren Enden des oberen Scherenarmpaars gelenkig mit den oberen Enden des unteren Scherenarmpaars verbunden sind und dass der Angriffspunkt für den Spindelantrieb wenigstens eine gelenkige Verbindung eines unteren Endes eines Scherenarms des oberen Scherenarmpaars mit dem zugehörigen oberen Ende eines Scherenarms des unteren Scherenarmpaars ist.This task comes with the characteristics of the preamble of claim 1 solved. Training and advantageous versions The invention is encompassed in the further claims Scissor lift device for a couch or a table, the scissor lifting device between a lower frame and a support for the bed or table is arranged, wherein the scissor lifting device consists of crossed shear arms the vertical and parallel on two sides of the carrier, or Frame are arranged, the shear arms articulated in the middle are connected to each other and being a spindle drive directly or acts indirectly on at least one end of a scissor arm, so that the scissor arms between an extended and a folded one Position are movable and each having an upper or lower End of a pair of scissor arms firmly connected to the frame or the carrier and the other end is slidable in or on the frame or carrier is arranged, characterized in that two pairs of scissor arms one above the other are arranged, the lower ends of the upper pair of scissors arms are articulated to the upper ends of the lower pair of scissor arms and that the point of attack for the spindle drive at least one articulated connection of a lower one End of a scissor arm of the upper pair of scissor arms with the associated upper one End of a scissor arm of the lower pair of scissor arms.
Nach einer bevorzugten Ausführung der Erfindung sind weist die Scherenhubvorrichtung einen elektromotorischen Antrieb auf. Der elektrische Antrieb ist fest mit dem Angriffspunkt für die Spindel verbunden und weist eine Antriebsmutter auf, die auf der Spindel läuft. Der Angriffspunkt ist eine Welle, die die oberen Scherenarmpaare und die unteren Scherenarmpaare verbindet, wobei der Antrieb im Wesentlichen vollständig zwischen den Scherenarmen beider Seiten angeordnet ist. Der Antrieb ist gelenkig auf der Welle angeordnet ist und die Spindel ist vertikal ausgerichtet. Die Spindel ist fest mit ihrem oberen oder unteren Ende mit dem Träger, bzw. dem Rahmen oder dem Boden verbunden und der Antrieb stützt sich mit der Antriebsmutter auf der Spindel ab. Die Verbindung zwischen dem Antrieb und der Antriebsmutter ist vorzugsweise ein Rohr, in das die Spindel einfährt.According to a preferred embodiment of the According to the invention, the scissor lifting device has an electric motor Drive on. The electric drive is fixed with the point of attack for the Spindle connected and has a drive nut on the spindle running. The point of attack is a wave that hits the top scissor arm pairs and connects the lower pairs of scissors arms, the drive in Essentially complete is arranged between the scissor arms on both sides. The drive is articulated on the shaft and the spindle is vertical aligned. The spindle is fixed with its top or bottom End with the carrier, or connected to the frame or the floor and the drive is supported with the drive nut on the spindle. The connection between the drive and the drive nut is preferably a tube, in that the spindle retracts.
Im Folgenden wird die Erfindung anhand von Zeichnungen beispielhaft näher beschrieben. Es zeigen:The invention is described below of drawings, for example described. Show it:
