Abstract
Description
Die Erfindung betrifft eine Verstellanordnung mit einem Scherengestell, insbesondere Federelement, mit den im Oberbegriff des Patentanspruches 1 angegebenen Merkmalen.The The invention relates to an adjustment arrangement with a scissor frame, in particular spring element, with the in the preamble of claim 1 specified characteristics.

Der Erfindung liegt die Aufgabe zu Grunde, eine Verstellanordnung mit den Merkmalen im Oberbegriff des Patentanspruches 1 anzugeben, die auf einfache Weise eine vielseitigere Anwendung beispielsweise als Federelement ermöglicht.Of the Invention is based on the object, an adjustment with indicate the features in the preamble of claim 1, the in a simple way a more versatile application for example as Spring element allows.
Diese Aufgabe ist durch die Merkmale im Patentanspruch 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen entnehmbar.These The object is solved by the features in claim 1. Advantageous embodiments of the invention are the subclaims removable.
Das zwischen zwei Stützteilen verstellbar angeordnete Scherengestell ist erfindungsgemäß von einem Kraftelement belastet oder belastbar, das durch seine Anordnung zwischen zwei Scherenelementen des Scherengestells an beiden Scheren elementen jeweils eine Kraft und/oder ein Moment bewirkt oder bewirken kann. Ein Verstellen zumindest eines Stützteiles oder der beiden Stützteile zueinander wird somit über die Kräfte und/oder Momente an beiden Stützstellen des Kraftelements in Abhängigkeit jeweils von der Lage der Stützteile zueinander beeinflusst. Die Verstellanordnung kann dadurch vielseitiger an unterschiedliche Verwendungen angepasst werden. Beispielsweise kann die Verstellanordnung auch als Federelement wirken, das einen nahezu beliebigen Kraft-Weg-Verlauf, beispielsweise einen progressiven, degressiven oder linearen Verlauf aufweisen kann. Ebenso ist es möglich, dass der Kraft-Weg-Verlauf eines derartigen Federelements über dem Weg mit nahezu konstanter Kraft oder einem geringen Kraftanstieg bzw. -abfall verläuft. Das Kraftelement kann über ein beliebiges Medium belastbar oder belastet sein. Beispielsweise ist das Kraftelement ein Hydraulikzylinder oder eine mechanische Feder, beispielsweise eine vorgespannte Zug- oder Druckfeder. Das Kraftelement kann auch eine Gasfeder sein, deren Druck beispielsweise ansteuerbar ist. Bei einfacheren Ausführungen weist die Verstellanordnung keine motorische Einrichtung auf. Bei aufwändigeren Ausführungen kann jedoch – dem jeweiligen Anwendungsfall entsprechend – eine motorische Einrichtung zum Belasten und/oder Verstellen des Scherengestells vorgesehen sein. Ein wesentlicher Vorteil der Verstellanordnung ist jedoch darin zu sehen, dass mit der Verstellanordnung viele Verstellungen mechanisch realisierbar sind, für die kein Motorantrieb bzw. Elektromotor erforderlich ist.The between two support members adjustably arranged scissors frame is loaded according to the invention by a force element or resilient, by its arrangement between two scissor elements of the scissors frame on both scissors elements each have a force and / or a moment causes or can cause. An adjustment of at least one Support member or the two support parts to each other is thus about the forces and / or moments at both Support points of the force element in dependence each influenced by the position of the support members to each other. The adjustment can thus be more versatile to different Uses are adjusted. For example, the adjustment act as a spring element, the almost any force-displacement curve, For example, have a progressive, degressive or linear course can. Likewise it is possible that the force-distance course such a spring element over the way with almost constant force or a small force increase or decrease. The force element can be loaded over any medium or be burdened. For example, the force element is a hydraulic cylinder or a mechanical spring, such as a preloaded tension or Spring. The force element may also be a gas spring whose Pressure is controllable, for example. For simpler versions the adjusting arrangement has no motor device. At more elaborate However, versions can - the particular application accordingly - a motor device for loading and / or adjusting the scissors-type frame. An essential Advantage of the adjustment is, however, to be seen in that with the adjustment many adjustments mechanically feasible are for which no motor drive or electric motor required is.

Alternativ zum Ausführungsbeispiel kann das Scherengestell mehr als zwei sich kreuzende Scherenelemente aufweisen. In diesem Fall ist jeweils ein Arm eines zweiarmigen Scherenelements mit einem anderen Arm eines zweiarmigen Scherenelements gelenkig verbunden, die nicht an einer gemeinsamen Kreuzungsstelle gelenkig verbunden sind. An Stelle der bei dem Ausführungsbeispiel verwendeten einarmigen Scherenelemente können auch zweiarmige Scherenelemente verwendet werden, wobei dann die einem Stützteil zugeordneten Arme der sich kreuzenden Scherenelemente direkt oder über eine Gelenkstelle mit dem betreffenden Stützteil verbunden sind.alternative to the embodiment, the scissors rack more than have two intersecting scissor elements. In this case is one arm of a two-armed scissor element with another Arm of a two-armed scissor element hinged, which is not are hinged at a common intersection. At Location of the one-armed used in the embodiment Scissor elements can also be two-armed scissor elements be used, in which case the arms associated with a support part the intersecting scissor elements directly or via a Joint are connected to the respective support member.
