Beschreibung
HandhebelpresseDescription
Hand lever press
Die Erfindung bezieht sich auf eine Handhebelpresse mit einem Hebel.The invention relates to a hand lever press with a lever.
Handhebelpressen sind an sich bekannt. Handhebelpressen, die anwendungsbedingt einen großen Hub ausführen müssen und im letzten Abschnitt des Hubes eine groß Kraft erfordern, benötigen einen großen Hebelweg und einen langen Hebel. Bei Serienfertigung führt dies für die Bedienperson zur einer Dauerbelastung des Schultergelenks, insbesondere beim Greifen des Hebels über die 90°-Ebene in seiner oben liegenden Ausgangssteilung. Derartige Belastungen können zu einem Schultergelenksyndrom führen. Weiterhin ist eine sekundäre Belastung der Halswirbelsäule und Brustwirbelsäule durch kompensatorische Schiefhaltung des Oberkörpers einschließlich Kopf möglich.Hand lever presses are well known. Hand lever presses that have to perform a large stroke due to their application and require a lot of force in the last section of the stroke require a large lever travel and a long lever. In series production, this leads to a permanent load on the shoulder joint for the operator, especially when gripping the lever over the 90° level in its upper starting position. Such loads can lead to shoulder joint syndrome. Furthermore, secondary loads on the cervical and thoracic spine are possible due to compensatory tilting of the upper body including the head.
Der Erfindung liegt die Aufgabe zugrunde, eine Handhebelpresse der oben genannten Art dahingehend zu verbessern, daß körperliche Belastungen der Bedienperson weitgehend vermieden werden.The invention is based on the object of improving a hand lever press of the above-mentioned type in such a way that physical strain on the operator is largely avoided.
Diese Aufgabe wird durch eine Handhebelpresse mit den Merkmalen nach Anspruch 1 gelöst, die durch einen Handgriff gekennzeichnet ist, der auf dem Hebel verschiebbar angeordnet ist, wodurch der wirksame Hebelarm bei Betätigung der Handhebel-0 presse veränderbar ist. Durch den während der Hebelbewegung veränderbaren Handgriff wird erreicht, daß der Hebel in seiner Ausgangslage in seinem unteren Bereich gegriffen werden kann. Ausgehend von dieser Griffposition ist der Hebel fast kraftlos nach unten schwenkbar, wobei der Handgriff den 5 Hebelarm verlängernd auf dem Hebel entlang verschiebbar ist, um schließlich mit einem langen Hebelarm eine große Preßkraft aufzubringen.This object is achieved by a hand lever press with the features of claim 1, which is characterized by a handle that is arranged so that it can be moved on the lever, whereby the effective lever arm can be changed when the hand lever press is operated. The handle, which can be changed during the lever movement, ensures that the lever can be gripped in its starting position in its lower area. Starting from this grip position, the lever can be pivoted downwards with almost no effort, whereby the handle can be moved along the lever, extending the lever arm, in order to finally apply a large pressing force with a long lever arm.

Mit der beschriebenen Lösung läßt sich, mit geringem Kostenaufwand
ein wesentlicher Gesundheitsschutz erreichen, wobei die Lösung im Rahmen einer Nachrüstung bei vorhandenen Handhebelpressen
möglich ist.
5With the solution described, significant health protection can be achieved at low cost, and the solution can be retrofitted to existing hand lever presses.

Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand einer Zeichnung näher erläutert. In der Figur ist eine Handhebelpresse 1 mit einem Hebel 2 dargestellt, der in seiner Ausgangsposition gezeigt ist. Auf dem Hebel 2 ist ein Handgriff in Pfeilrichtung 4 verschiebbar angebracht. In der Ausgangsposition des Hebels 2, in der er senkrecht nach oben steht, befindet sich der Handgriff 3 in der unteren Position, in der er vorteilhafter Weise von der Bedienperson leicht gegriffen werden kann. Beim Schwenken des Hebels 2 in die waagerechte Position (siehe Figur) wird der Handgriff 3 vorteilhafter Weise an das Ende des Hebels 4 verschoben, um mit diesem langen Hebelarm eine große Presskraft zu erreichen.An embodiment of the invention is explained in more detail below using a drawing. The figure shows a hand lever press 1 with a lever 2, which is shown in its starting position. A handle is attached to the lever 2 so that it can be moved in the direction of the arrow 4. In the starting position of the lever 2, in which it is vertically upwards, the handle 3 is in the lower position, in which it can advantageously be easily gripped by the operator. When the lever 2 is pivoted into the horizontal position (see figure), the handle 3 is advantageously moved to the end of the lever 4 in order to achieve a high pressing force with this long lever arm.
