Description
Die Erfindung betrifft einen Arbeits- und Montagetisch mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a work and assembly table with the features of the preamble of
Ein solcher Arbeits- und Montagetisch ist beispielsweise in dem Prospekt "Ergonomisch, sicher, wirtschaftlich, vielseitig NIVEAU-höhenverstellbare Arbeitstische" der Reinhold Beck Maschinenbau GmbH, D-72505 Krauchenwies, offenbart.Such a work and assembly table, for example, in the prospectus "Ergonomic, safe, economical, versatile LEVEL height-adjustable work tables" of Reinhold Beck Maschinenbau GmbH, D-72505 Krauchenwies disclosed.
Ein üblicher Einsatzbereich gattungsgemäßer Arbeitstische, die oft auch als Arbeits- oder Montagewagen bezeichnet werden, wenn sie rollbar ausgeführt sind, sind Werkstätten oder Produktionshallen. Generell ist die Erfindung jedoch auch auf andere Arten übertragbar, beispielsweise auf Montagebänke. Auch dabei ist die Ausrichtung einer Arbeits- oder Montagefläche von Bedeutung. Die Höhe der Fläche muss beispielsweise aus ergonomischen Gründen in ihrer Höhe verstellbar sein.A common use of generic work tables, which are often referred to as work or assembly cars, if they are designed rollable, are workshops or production halls. In general, however, the invention can also be applied in other ways, for example on assembly benches. Again, the orientation of a work or mounting surface is important. For example, the height of the surface must be adjustable in height for ergonomic reasons.
Die Höhenverstellung gattungsgemäßer Arbeitstische ist manuell, beispielsweise über ein Fußpedal, betätigbar, ohne eine Notwendigkeit eines Anschlusses an ein Netz. Die Erfindung ist gleichwohl auch auf Arbeitstische übertragbar, die an ein elektrisches oder sonstiges Netz angeschlossen sind, beispielsweise ein Arbeitstisch gemäß
Bei bekannten Arbeitstischen ist unterhalb der ausgerichteten Arbeitsfläche wenig Raum gelassen, um beispielsweise andere Gegenstände dort unterbringen zu können. Oft ist dieser Raum durch aufwändige Konstruktionen, die die Stabilität des Arbeitstischs gewährleisten sollen, verbaut. So ist beispielsweise als Synchronisationseinrichtung und Hubeinrichtung für die Höhenverstellung bei definierter Ausrichtung des Arbeitstisches eine Scherenkonstruktion in einem bekannten Untergestell vorgesehen. Alternativ werden gemäß
Aus der
Es besteht ein Problem darin, unterhalb der Arbeitsfläche Raum für andere Verwendungen freizuhalten und dennoch die Ausrichtung der Arbeitsfläche bei Verstellung deren Höhe über nur eine Betätigungseinrichtung ohne aufwändige Steuerungen beizubehalten. Hierfür ist ein Arbeits- und Montagetisch zu entwickeln, der möglichst einfach im Aufbau und einfach zu montieren ist. Er soll zuverlässig und auch bei hohen Traglasten die Ausrichtung der Arbeitsfläche sicherstellen.There is a problem in keeping space for other uses underneath the work surface while still maintaining the alignment of the work surface when adjusting its height over only one actuator without expensive controls. For this purpose, a work and assembly table is to be developed, which is as simple as possible in construction and easy to assemble. It is intended to ensure the alignment of the work surface reliably and at high loads.
Das Problem wird gelöst durch einen Arbeits- und Montagetisch mit den kennzeichnenden Merkmalen des Anspruchs 1.The problem is solved by a working and assembly table with the characterizing features of

Der Arbeits- und Montagetisch 10 gemäß dem ersten Ausführungsbeispiel (
Die Seitenwangen 122 (
Da die Hubzylinder 148 den Auflagerahmen 12 ohne aufwändige Steuerungsmaßnahmen nicht gleichmäßig anheben würden, ist aus Präzisionsgründen eine exakte Parallelverschiebung des Auflagerahmens 12 nach oben oder unten über eine Synchronisiereinrichtung 16 gewährleistet. Die durch die Hubeinrichtung 147 vorgegebene vertikale und damit lineare Bewegung wird auf eine entlang der Längsachse ausgerichtete Synchronwelle 161 übertragen. Dazu weist die Synchronwelle 161 endseitig Kettenräder 162, 163 als Drehmomentübertragungselemente auf. Die Kettenräder 162, 163 greifen jeweils in eine Kette ein.Since the
Auf einer der kurzen Seiten, die auch als Antriebsseite bezeichnet werden kann, ist eine Antriebskette als Kraftübertragungselement 164 mit dem Auflagerahmen 12 verbunden (
Aus der Beschreibung zur Befestigung der Ketten 164 geht eindeutig hervor, dass an zwei Angriffspunkten die Synchronisiereinrichtung 16 mit dem Auflagerahmen 12 verbunden werden muss. Eine besonders einfache Montierbarkeit ist die Folge. Alternativ zur Antriebskette oder Abtriebskette kann gleichwirkend jeweils eine Mehrfachkettenkonstruktion oder eine Konstruktion mit Riemen oder starren Kraftübertragungselementen vorgesehen sein. Gleichwirkenden flexiblen oder starren Kraftübertragungselementen ist gemein, dass sie einen Formschluss zu Drehmomentübertragungselementen herstellen.From the description of the attachment of the

Es ist bei den dargestellten Ausführungsbeispielen somit gelungen, den Aufgaben Synchronisierung, Hub, Seitenführung jeweils eigene Einrichtungen zuzuweisen, die rein mechanisch miteinander gekoppelt sind. Es ist ein modularer Aufbau des Tisches ermöglicht, der zudem eine weitgehend freie Nutzung des Raums unterhalb des Auflagerahmens 12 gestattet. Je nach Anforderung an die weitere Ausgestaltbarkeit des Raumes unterhalb des Auflagerahmens 12 kann eine Positionierung der Synchronwelle 161 direkt unterhalb des Auflagerahmens 12 von Vorteil sein oder aber eine Anordnung der Synchronwelle 161 weiter unten (nicht dargestellt), wenn beispielsweise Schubladen direkt unter dem Auflagerahmen 12 Platz finden sollen.
Durch den modularen Aufbau sind andere Arbeits- und Montagetische oder Auflagerahmen in gleiche Untergestelle einsetzbar. Es können beliebig viele Hubeinrichtungen auf einer oder auf beiden kurzen Seiten vorgesehen werden, je nach geforderter Belastbarkeit. Eine Befestigung der Synchronisiereinrichtung 16 ist auf der Antriebsseite an der Seitenwange 122 oben und auf der Abtriebsseite an der Seitenwange 122 unten vorgesehen.It is thus succeeded in the illustrated embodiments, assign the tasks synchronization, hub, side guide each own facilities that are purely mechanically coupled together. It is a modular construction of the table allows, which also allows a largely free use of the space below the
Due to the modular design other work and assembly tables or support frame in the same bases are used. It can be provided on one or both short sides as many lifting devices, depending on the required load capacity. An attachment of the
