Description

Die Erfindung betrifft eine Hebewandvorrichtung mit wenigstens einer Hebewand, die über wenigstens zwei Führungsvorrichtungen höhenverstellbar ist, so dass die Hebewand von einer ersten Position (EP) in eine zweite Position (ZP) und zurück überführbar ist, sowie wenigstens einem Kraftspeicher.The invention relates to a hoisting device with at least one lifting wall, which is height-adjustable via at least two guiding devices, so that the lifting wall can be moved from a first position (EP) to a second position (ZP) and back, as well as at least one energy accumulator.

Derartige Hebewandvorrichtungen sind bereits aus dem Stand der Technik bekannt.Such lifting wall devices are already known from the prior art.

So beschreibt die DE 10 2006 034 332 B4 einen Büroarbeitsplatz, insbesondere einen Bildschirmarbeitsplatz mit einer daran angeordneten Hebewandvorrichtung. Diese umfasst eine Hebewand, die höhenverstellbar an einer Tischplatte angeschlossen und zwischen einer abgesenkten Stellung und eine erhabene Stellung höhenverstellbar ist. Diese Hebewandvorrichtung ist fest mit dem Tisch montiert und kann nicht an die Bedürfnisse des an diesem Tisch arbeitenden Menschen in Bezug auf die Sicht- und Lichtverhältnisse bzw. auch die Akustik angepasst werden. Weiterhin ist die Verlegbarkeit von Anschlussleitungen für Bürokommunikationsmittel wie Telefonkabel, Computerkabel und dergleichen von und zu dem Bürotisch stark eingeschränkt, das sämtliche Leitungen immer um die Hebewand herumgeführt werden müssen.
Ebenfalls nachteilig ist der komplizierte mechanische Aufbau mit der massiven Stellstange und der sich daran abwälzenden Führungsrolle in Verbindung mit der zusätzlich angeordneten Druckfeder, insbesondere der Gasdruckfeder.That's how it describes DE 10 2006 034 332 B4 an office workstation, in particular a VDU workstation with a lifting wall device arranged thereon. This comprises a lifting wall, which is height-adjustable connected to a table top and height adjustable between a lowered position and a raised position. This lifting device is firmly mounted to the table and can not be adapted to the needs of the person working on this table in terms of visibility and lighting conditions or the acoustics. Furthermore, the availability of connection cables for office communication equipment such as telephone cables, computer cables and the like from and to the office table is severely limited, that all lines must always be guided around the hoistway.
Also disadvantageous is the complicated mechanical structure with the solid control rod and the rolling role leading to it in conjunction with the additionally arranged compression spring, in particular the gas spring.

Hier setzt die Erfindung ein, die sich die Aufgabe gestellt hat, die Nachteile des bekannten Standes der Technik zu überwinden und eine Hebewandvorrichtung aufzuzeigen, die kostengünstig und wirtschaftlich herstellbar ist, die einfach und mit geringem Kraftaufwand höhenverstellbar sowie leicht an Tischen, Schränken und dergleichen montierbar ist.This is where the invention, which has set itself the task of overcoming the disadvantages of the known prior art and to show a hoistway device, which is inexpensive and economical to produce, the height adjustable easily and with little effort and easily mounted on tables, cabinets and the like is.

Gelöst wird diese Aufgabe mit einer Hebewandvorrichtung gemäß den Merkmalen des Anspruches 1. Weitere vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben.This object is achieved with a hoistway device according to the features of claim 1. Further advantageous embodiments are described in the subclaims.

Die JP 2005/118258 A _beschreibt eine Hebewandvorrichtung mit wenigstens einer Hebewand, die über wenigstens zwei Führungsvorrichtungen höhenverstellbar ist, sodass die Hebewand von einer ersten Position EP in eine zweite Position ZP und zurück überführbar ist. Weiterhin ist offenbart, dass an den unteren freien Enden der Hebewand einen Profilabschnitt, an dessen freien Enden jeweils ein Rastelement angeordnet ist. Dieses Rastelement umfasst eine Kugel und eine diese unterstützende Spiralfeder, die dazu dienen, die Hebewand in den Führungsvorrichtungen in bestimmten Höhenpositionen zu arretieren. Die D1 offenbart weiterhin, dass die erste Führungsvorrichtung an der zweiten Führungsvorrichtung, mit dieser in Wirkverbindung stehend angeordnet ist und das die Spiralfeder an wenigstens einer Führungsvorrichtung fixiert ist.The JP 2005/118258 A describes a hoistway device with at least one hoistway which is height adjustable via at least two guide devices so that the hoistway can be moved from a first position EP to a second position ZP and back again. Furthermore, it is disclosed that at the lower free ends of the lifting wall a profile section, at whose free ends in each case a latching element is arranged. This locking element comprises a ball and a supporting spiral spring, which serve to lock the lifting wall in the guide devices in certain height positions. D1 further discloses that the first guide device is arranged on the second guide device, in operative connection therewith, and that the spiral spring is fixed to at least one guide device.

Es hat sich überraschend herausgestellt, dass eine Hebewandvorrichtung mit wenigstens einer Hebewand, die über wenigstens zwei Führungsvorrichtungen höhenverstellbar ist, so dass die Hebewand von einer ersten Position EP in eine zweite Position ZP und zurück überführbar ist, sowie wenigstens einem Kraftspeicher sich dadurch auszeichnet, dass die erste Führungsvorrichtung an der zweiten Führungsvorrichtung, mit dieser in Wirkverbindung stehend angeordnet ist, das der Kraftspeicher an wenigstens einer Führungsvorrichtung mit der anderen Führungsvorrichtung in Wirkverbindung stehend, fixiert ist und das die zweite Führungsvorrichtung wenigstens ein Halteelement aufweist. Hierdurch kann vorteilhafterweise die Hebewand flexibel in der Höhe verstellt werden, ohne das zusätzliche Halte- bzw. Rastelemente erforderlich sind.
Weiterhin ist es vorteilhafterweise möglich, neben der einfachen mechanischen Beweglichkeit der erfindungsgemäßen Hebewandvorrichtung diese hinsichtlich ihrer Breite bzw. Größe allen Anforderungen gemäß anzupassen und so über beispielsweise geeignete Halteeinrichtungen diese an Tischen aber auch an Schränken und ähnlichen Öffnungen zu positionieren und in bestimmungsgemäßer Weise zu nutzen.
Dabei hat es sich weiterhin als vorteilhaft herausgestellt, dass der Kraftspeicher an der ersten Führungseinrichtung, mit der zweiten Führungseinrichtung in Wirkverbindung stehend, fixiert ist.
Weiterhin vorteilhaft bei der erfindungsgemäßen Hebewandvorrichtung ist es, dass der Kraftspeicher an der zweiten Führungseinrichtung, mit der ersten Führungseinrichtung in Wirkverbindung stehend, fixiert ist.
Hierdurch kann durch unterschiedliche Dimensionierung der Kraftspeicher eine kostengünstige und wirtschaftliche Herstellung der erfindungsgemäßen Hebewandvorrichtung realisiert werden, wobei diese beispielsweise an einem Tisch befestigt, sehr einfach von einer ersten Position EP in eine zweite Position ZP und zurück überführbar ist, ohne das hierzu ein hoher Kraftaufwand bzw. zusätzliche elektrische Unterstützungselemente erforderlich sind. Es hat sich weiterhin als vorteilhaft herausgestellt, dass der Kraftspeicher dabei als Rollzugfelder ausgebildet ist. Hierdurch lässt sich je nach Größe und Gewicht der Hebewand problemlos der Kraftspeicher so dimensionieren, dass bei der erfindungsgemäßen Hebewandvorrichtung die Hebewand leicht und mit geringem ohne Kraftaufwand von einer ersten Position EP in eine zweite Position ZP und zurück höhenverstellbar überführbar ist.
