Description

Die Erfindung bezieht sich auf einen Handhebel mit Befestigungselement, für eine Spindel, Achse od. dgl, wobei der Handhebel und das Befestigungselement in Längsrichtung der Hebel-Drehachse mittels zweier Kupplungselemente drehfest axial kuppelbar sind und der Handhebel aus einem weicheren Werkstoff als das aus Metall hergestellte Befestigungselement gefertigt ist und das handhebelseitige Kupplungselement aus Metall besteht sowie drehfest im Werkstoff des Handhebels verankert ist, wobei Kupplungsglieder des handhebelseitigen Kupplungselements mit Kupplungs-Gegengliedern des befestigungselementseitigen Kupplungselementes kuppelbar sind. Ein derartiger Handhebel mit Befestigungselement ist durch die DE-B-1 278 860 bekannt geworden. Die Kupplung ist als Rastkupplung ausgebildet und befindet sich im Innern der mit einer zentrischen Sackbohrung ausgestatteten Spindel. Weil dieser Handhebel rotationssymetrisch geformt ist muß auf ein besonderes Ausrichten in Drehrichtung gegenüber der Achse od. dgl. nicht geachtet werden. Theoretisch bestehen aufgrund der speziellen Ausbildung der rastenden Kupplungsverbindung zwei um 180° gegeneinander versetzte Montagemöglichkeiten.The invention relates to a hand lever with a fastening element for a spindle, axle or the like, the hand lever and the fastening element being axially non-rotatably coupled in the longitudinal direction of the lever axis of rotation by means of two coupling elements, and the hand lever made of a softer material than that made of metal Fastening element is made and the hand lever-side coupling element consists of metal and is anchored in the material of the hand lever in a rotationally fixed manner, coupling members of the hand lever-side coupling element being able to be coupled to coupling counter-members of the fastening element-side coupling element. Such a hand lever with fastening element is known from DE-B-1 278 860. The coupling is designed as a snap-in coupling and is located inside the spindle, which is equipped with a central blind hole. Because this hand lever is rotationally symmetrical, special alignment in the direction of rotation with respect to the axis or the like need not be taken into account. In theory, due to the special design of the locking coupling connection, there are two mounting options offset by 180 °.

Wenn der Handhebel mehrere im Winkel gegeneinander versetzte Stellungen bezüglich der Spindel oder Achse einnehmen soll, so ist diese vorbekannte Konstruktion hierfür nicht brauchbar. So gibt es beispielsweise Anwendungsgebiete, bei denen ein insbesondere mit einem radial abstehenden Griffstück versehener Handhebel vor Beginn der Drehung oder eventuell auch nach einer gewissen Teildrehung gegenüber der Spindel, Achse od. dgl. eine bzw. jeweils wieder eine vorgegebene Position einnehmen muß. Ein bevorzugtes Anwendungsgebiet sind Klemmhebel, wie man sie in der Technik insbesondere in Verbindung mit Werkzeugmaschinen, verwendet bzw. Klemmvorrichtungen zum Festhalten von Werkstücken die auf solchen Werkzeugmaschinen bearbeitet werden sollen.If the hand lever is to assume several positions with respect to one another at an angle with respect to the spindle or axis, then this previously known construction cannot be used for this. For example, there are areas of application in which a hand lever, in particular provided with a radially projecting handle, has to assume a predetermined position before the start of the rotation or possibly also after a certain partial rotation with respect to the spindle, axis or the like. A preferred field of application are clamping levers, such as those used in technology, in particular in connection with machine tools, or clamping devices for holding workpieces which are to be machined on such machine tools.

Man könnte zwar gemäß einem anderen Vorschlag dieser Vorveröffentlichung den Handhebel mittels einer Befestigungsschraube über einen Reibschluß mit der Antriebswelle od. dgl. kuppeln, jedoch würde das Umsetzen eines derartigen Handhebels stets das Lösen der Befestigungsschraube erfordern. Dies ist nicht praktikabel und aus diesem Grunde bei jenem Handhebel mit Befestigungselement auch nicht vorgesehen.According to another proposal of this prior publication, one could couple the hand lever by means of a fastening screw via a frictional connection with the drive shaft or the like. However, the implementation of such a hand lever would always require the fastening screw to be loosened. This is not practical and for this reason is also not provided for that hand lever with fastening element.

Durch die CH-A-309 659 ist ein anderer Handhebel mit Befestigungselement bekannt geworden, der ein Umsetzen des Handhebels gegenüber der Spindel oder Achse um kleine Drehwinkel zuläßt. Ein handhebelseitiges Kupplungselement ist in eine Bohrung des Handhebels eingeschoben und somit in Drehrichtung nicht sehr drehfest gehalten. Aufgrund der Dünnwandigkeit dieser Hülse und der verschiebbaren Lagerung des darin befindlichen Befestigungselements kommt ein enger Preßsitz mit entsprechender Reibkraft nicht in Frage. Problemhaft ist dort auch die äußere Abstützung der Feder für die axial belastete Kupplung.Another hand lever with fastening element has become known from CH-A-309 659, which allows the hand lever to be moved relative to the spindle or axis by small angles of rotation. A hand lever-side coupling element is inserted into a hole in the hand lever and is therefore not held in a rotationally fixed manner in the direction of rotation. Due to the thin walls of this sleeve and the displaceable mounting of the fastener located therein, a tight press fit with a corresponding frictional force is out of the question. The external support of the spring for the axially loaded coupling is also problematic there.

Die Aufgabe der Erfindung besteht nun darin, einen Handhebel mit Befestigungselement gemäß dem Oberbegriff des Anspruchs 1 so weiterzubilden, daß ein Umsetzen des Handhebels gegenüber dem Befestigungselement um kleine Drehwinkel möglich ist, wobei die Kupplung beider Teile robust ausgebildet sein soll bei sicherem Festhalten der beiden Kupplungselemente am Handhebel einerseits und am Befestigungselement andererseits.The object of the invention is to develop a hand lever with a fastener according to the preamble of claim 1 so that it is possible to move the hand lever relative to the fastener by small angles of rotation, the coupling of both parts should be robust while securely holding the two coupling elements on the hand lever on the one hand and on the fastener on the other.

Zur Lösung dieser Aufgabe wird erfindungsgemäß vorgeschlagen, daß der Handhebel mit Befestigungselement gemäß dem Oberbegriff des Anspruchs 1 entsprechend dem kennzeichnenden Teil dieses Anspruchs ausgebildet ist. Weil die Kupplungsglieder in an sich bekannter Weise durch eine Innen- und eine Außenverzahnung gebildet sind, kann der Handhebel entsprechend der Zahnteilung um jeweils kleine Drehwinkel gegenüber dem Befestigungselement versetzt werden. Die Federbelastung der axialen Kupplung sorgt für ein sicheren Einrasten nach dem Einstellen. Die Federkraft wird dabei sicher auf das Befestigungselement einerseits und das Kupplungselement des Handhebels andererseits übertragen. Außerdem ist das handhebelseitige Kupplungselement auf Grund der Verankerungselemente sicher im vergleichsweise weicheren Werkstoff des Handhebels verankert, so daß beispielsweise bei der Verwendung dieses Handhebels als Spannhebel auch die notwendige Handkraft beschädigungssicher aufgegeben werden kann. Durch die Verwendung von Metall für die beiden Kupplungselemente ist dort das Übertragen der Kraft im Rahmen der üblichen Belastungen eines derartigen Handhebels ohnehin verformungssicher möglich. Das Ausrasten der Kupplung erfolgt in axialer Richtung des Befestigungselements bei gleichzeitigem Spannen der Schraubendruckfeder. Ihre Kraft besorgt dann nach dem Loslassen des Handhebels und vorangegangener Relativdrehung gegenüber dem Befestigungselement das Einrasten der Kupplung. Die Verwendung von Kunststoff für den Handhebel ergibt die üblichen bekannten Vorteile, insbesondere das geringe Gewicht und den günstigen Herstellungspreis. Es entfallen auch eine Oberflächenveredelung und gegebenenfalls -bearbeitung.To achieve this object, it is proposed according to the invention that the hand lever with fastening element is designed according to the preamble of claim 1 in accordance with the characterizing part of this claim. Because the coupling members are formed in a manner known per se by an internal and an external toothing, the hand lever can be displaced in relation to the fastening element by small angles of rotation in accordance with the tooth pitch. The spring loading of the axial coupling ensures that it locks into place after adjustment. The spring force is safely transmitted to the fastening element on the one hand and the coupling element of the hand lever on the other hand. In addition, the coupling element on the hand lever side is securely anchored in the comparatively softer material of the hand lever due to the anchoring elements, so that, for example, when using this hand lever as a tensioning lever, the necessary manual force can also be safely released. The use of metal for the two coupling elements makes it possible to transmit the force in a deformation-resistant manner within the usual loads of such a hand lever. The clutch disengages in the axial direction of the fastening element with simultaneous tensioning of the helical compression spring. After releasing the hand lever and preceding relative rotation with respect to the fastening element, your force then ensures that the coupling engages. The use of plastic for the hand lever gives the usual known advantages, in particular the low weight and the low manufacturing price. There is also no need for surface finishing and, if necessary, processing.

Form und Größe der Verankerungselemente hängt nicht zuletzt vom Material des Handhebels sowie der Befestigungsart des handhebelseitigen Kupplungselements im Material des Handhebels ab. Zweckmäßigerweise wird das handhebelseitige Kupplungselement mit dem Kunststoff des Handhebels umspritzt. Es ist selbstverständlich, daß dabei die Kupplungszähne freigehalten werden, so daß Nacharbeiten an dieser Stelle entfallen.The shape and size of the anchoring elements depends not least on the material of the hand lever and the type of fastening on the hand lever side Coupling element in the material of the hand lever. The hand lever-side coupling element is expediently extrusion-coated with the plastic of the hand lever. It goes without saying that the clutch teeth are kept free, so that reworking is not necessary at this point.

Die Ausbildung der Kupplung über eine Innenverzahnung und Außenverzahnung führt zu maximal großen Zähnen und damit zu einer hochbelastbaren Zahnverbindung. Beim Stützglied für das befestigungselementferne Federende kann es sich beispielsweise um eine Schraube handeln, deren Kopfunterseite die Stützfläche für die vorteilhafterweise als Schraubendruckfeder ausgebildete Druckfeder bildet. Dadurch läßt sich die Einheit in besonders einfacher Weise montieren. Außerdem kann die axiale Relativbewegung zwischen Handhebel und Befestigungselement dadurch begrenzt werden, daß die Feder nach einer vorbestimmten Druckbewegung des Handhebels in Blocklage ist.The formation of the coupling via an internal toothing and an external toothing leads to teeth of maximum size and thus to a heavy-duty tooth connection. The support member for the spring element remote from the fastening element can be, for example, a screw, the underside of the head of which forms the support surface for the compression spring which is advantageously designed as a compression coil spring. This allows the unit to be assembled in a particularly simple manner. In addition, the axial relative movement between the hand lever and the fastening element can be limited in that the spring is in a block position after a predetermined pressure movement of the hand lever.

In weiterer Ausgestaltung der Erfindung wird vorgeschlagen, daß die Verankerungselemente des handhebelseitigen Kupplungselements aus gleichmäßig am Außenumfang angeordneten Zapfen, Warzen od. dgl. abstehenden Elementen bestehen. "Am Außenumfang" bedeutet jedoch nicht, daß die Zapfen od. dgl. in radialer Richtung abstehen müssen, vielmehr ist, insbesondere beim Ausführungsbeispiel der Erfindung, ein Abstehen in Achsrichtung von der betreffenden Ringfläche aus vorgesehen.In a further embodiment of the invention, it is proposed that the anchoring elements of the coupling element on the hand lever side consist of pins, warts or the like which protrude evenly on the outer circumference. However, “on the outer circumference” does not mean that the pins or the like have to protrude in the radial direction, rather, in particular in the exemplary embodiment of the invention, a protrusion in the axial direction from the ring surface in question is provided.

Eine weitere Ausbildung der Erfindung besteht darin, daß die Kupplungs-Gegenglieder des befestigungselementseitigen Kupplungselements durch die Zähne eines am inneren Ende des Befestigungselements angebrachten, insbesondere angeformten Ritzels mit Außenverzahnung gebildet sind, wobei die Zähne der Kupplungsglieder und Kupplungs-Gegenglieder in Zahnlängsrichtung ein- und auskuppelbar sind und die Kupplung axial in Einrastrichtung federbelastet ist Aufgrund der Federbelastung sind der Handhebel und das Befestigungselement stets drehfest miteinander gekuppelt, so daß bei drehfester Verbindung des Befestigungselements mit einer Spindel, Achse od. dgl. ein Drehen des Handhebels auch ein Drehen der Spindel od. dgl bewirkt. Wenn nun aber der Handhebel gegenüber der momentanen Stellung der Spindel od. dgl. in Drehrichtung versetzt werden soll, so hebt man ihn bei festgehaltener Spindel entgegen dem Widerstand beispielweise nach oben hin vom Befestigungselement ab und dreht ihn um den vorgesehenen Drehwinkel. Die Verzahnung läßt allerdings nur ein stufesweises Versetzen zu. Dies ist jedoch in den meisten Anwendungsfällen ohne Nachteil.A further embodiment of the invention consists in that the coupling counter-members of the fastening element-side coupling element are formed by the teeth of a pinion with external toothing attached, in particular molded, to the inner end of the fastening element, the teeth of the coupling members and coupling counter-members being able to be engaged and disengaged in the tooth longitudinal direction are and the clutch is spring-loaded axially in the snap-in direction Due to the spring load, the hand lever and the fastening element are always non-rotatably coupled, so that when the fastening element is connected to a spindle, axis or the like in a rotationally fixed manner, turning the hand lever or rotating the spindle or. The like causes. If, however, the hand lever is to be displaced in the direction of rotation relative to the current position of the spindle or the like, it is lifted against the fastening element, for example upwards, against the resistance, and is rotated by the intended angle of rotation. The teeth, however, only allow a gradual shift. However, this is without disadvantage in most applications.

Eine Weiterbildung der Erfindung sieht vor, daß das Befestigungselement als Hülse oder topfförmiges Element mit innenliegendem Topfboden ausgebildet ist, das längsverschieb-und drehbar in einem hülsenförmigen Ansatz des Handhebels gelagert ist. Bei Verwendung einer Schraube als Stützglied kann im Topfboden ein zentrisches Muttergewinde zum Eindrehen der Schraube vorgesehen sein. Zweckmäßigerweise hat die Schraube nur über einen Teil ihres Schaftes ein Gewinde, so daß man über die Länge des Gewindeteils die Einschraubtiefe festlegen kann.A further development of the invention provides that the fastening element is designed as a sleeve or cup-shaped element with an inner pot base, which is mounted so as to be longitudinally displaceable and rotatable in a sleeve-shaped extension of the hand lever. When using a screw as a support member, a central nut thread can be provided in the pot base for screwing in the screw. The screw expediently has a thread only over part of its shank, so that the screw-in depth can be determined over the length of the threaded part.

Die Erfindung wird nachstehend anhand der Zeichnung näher erläutert.The invention is explained below with reference to the drawing.

Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung. Hierbei stellen dar:

  • Fig. 1 einen Längsmittelschnitt durch den Handhebel mit dem Befestigungselement,
  • Fig. 2 eine Draufsicht auf den Handhebel der Fig. 1,

The drawing shows an embodiment of the invention. Here represent:
  • 1 shows a longitudinal central section through the hand lever with the fastening element,
  • 2 is a plan view of the hand lever of FIG. 1,
  • Fig. 3 top views of the top and bottom of the hand lever. 4-sided coupling element.

Der Handhebel 1 besteht aus einem Material vergleichsweise geringer Härte, insbesondere aus Kunststoff. An seinem dem Befestigungselement 2 zugekehrte Ende besitzt er eine hülsenförmige Gestalt, an die sich ein im Querschnitt U-förmiges Griffstück anschließt. Das freie Ende besitzt etwas längere U-Flanken und es ist durch eine Zwischenwand 3 verstärkt. Das Befestigungselement 2 hat, wie insbesondere die Fig. 1 zeigt, eine im wesentlichen hülsenförmige Gestalt. An seinem äußeren Ende trägt es ein Muttergewinde 4 und an seinem inneren ein Muttergewinde 5. Letzteres ist wesentlich kürzer und im Durchmesser kleiner als das Muttergewinde 4. Es nimmt den mit Gewinde versehenen Schaftteil 6 einer Schraube 7 auf. Der gewindelose Schaftteil 8 ist von einer konischen Schraubendruckfeder 9 umgeben. Ihr im Durchmesser kleineres Ende stützt sich an der Unterseite des Schraubenkopfes 10 ab, während das größere Federende auf der zugekehrten ringförmigen Fläche eines handhebelseitigen Kupplungselements 11 aufliegt.The hand lever 1 consists of a material of comparatively low hardness, in particular of plastic. At its end facing the fastening element 2, it has a sleeve-like shape, which is followed by a handle piece with a U-shaped cross section. The free end has slightly longer U flanks and it is reinforced by an intermediate wall 3. The fastening element 2, as shown in particular in FIG. 1, has an essentially sleeve-like shape. It has a nut thread 4 at its outer end and a nut thread 5 at its inner end. The latter is considerably shorter and smaller in diameter than the nut thread 4. It receives the threaded shaft part 6 of a screw 7. The threadless shaft part 8 is surrounded by a conical helical compression spring 9. Its smaller end is supported on the underside of the screw head 10, while the larger spring end rests on the facing annular surface of a coupling element 11 on the lever side.

Das in den Fign. 3 und 4 detailliert dargestellte handhebelseitige Kupplungselement 11 ist in den Werkstoff bzw. Kunststoff des Handhebels 1 bzw. des hülsenförmigen Handhebelteils 12 eingebettet bzw. teilweise vom Kunststoff umspritzt. An seiner vom Befestigungselement (2) wegweisenden Seite trägt das Kupplungselement 11 am Umfang insbesondere gleichmäßig verteilte, der Verankerung im Kunststoffmaterial dienende zapfen- oder warzenförmige Verankerungselemente 13. An der gegenüberliegenden Unterseite des Kupplungselementes 11 ist ein Zahnkranz 14 mit nach innen weisenden, Kupplungsglieder 15 bildenden Zähnen angeformt. Letztere erstrecken sich demnach parallel zur Achse 16 einer mit dem Befestigungselement 2 zu verbindenden Spindel 17 od. dgl. und sie bilden Kupplungs-Gegenglieder. Auf das nach oben ragende Spindelende ist das Befestigungselement 2 mit seinem Muttergewinde 4 aufgeschraubt.The in Figs. 3 and 4, hand lever-side coupling element 11, which is shown in detail, is embedded in the material or plastic of the hand lever 1 or of the sleeve-shaped hand lever part 12 or is partially extrusion-coated with the plastic. On its side facing away from the fastening element (2), the coupling element 11 carries, in particular, evenly distributed peg-shaped or wart-shaped anchoring elements 13 on the circumference, which serve for anchoring in the plastic material Molded teeth. The latter accordingly extend parallel to the axis 16 of a spindle 17 or the like to be connected to the fastening element 2 and they form coupling counter-elements. The fastening element 2 is on the upwardly projecting spindle end screwed on its mother thread 4.

Am nach oben weisenden, eingesteckten inneren Ende des Befestigungselements 2 ist ein befestigungselementseitiges Kupplungselement 18 angeformt. Es hat die Gestalt eines Ritzels mit Außenverzahnung. Die Zähne 19 dieses Ritzels entsprechen in Form, Größe und Teilung denjenigen des Zahnkranzes 14. Das Ritzel und der Zahnkranz sind aufgrund der Kraft der Druckfeder 9 in Eingriff miteinander, d. h. über diese beiden Teile sind der Handhebel und das Befestigungselement 2 miteinander gekuppelt. Zum Auskuppeln zieht man bei festgehaltener Spindel 17 den Handhebel 1 im Sinne des Pfeils 20 nach oben, wodurch die Feder 9 gegebenenfalls bis zur Blocklage zuammengedrückt wird. Nachfolgend kann man den Handhebel 1 senkrecht zur Bildebene gegenüber dem Befestigungselement 2 um einen vorgegebenen Winkel drehen. Sobald die Zähne und Zahnlücken der beiden Kupplungsteile wieder in geeigneter Zuordnung stehen, wird die Kupplung beim Loslassen des Handhebels 1 aufgrund der Spannung der Feder 9 wieder eingerückt.A coupling element 18 on the fastening element side is molded onto the inserted, inner end of the fastening element 2 pointing upwards. It has the shape of a pinion with external teeth. The teeth 19 of this pinion correspond in shape, size and pitch to those of the ring gear 14. The pinion and the ring gear are in engagement with one another due to the force of the compression spring 9, i. H. The hand lever and the fastening element 2 are coupled to one another via these two parts. To disengage, pull the hand lever 1 in the direction of arrow 20 while the spindle 17 is held tight, whereby the spring 9 may be compressed to the block position. You can then turn the hand lever 1 perpendicular to the image plane relative to the fastening element 2 by a predetermined angle. As soon as the teeth and tooth gaps of the two coupling parts are again in a suitable assignment, the coupling is engaged again when the hand lever 1 is released due to the tension of the spring 9.

Nachdem das Befestigungselement 2 aus einem festen bzw. harten Werkstoff, vorzugsweise Metall, besteht und auch das handhebelseitige Kupplungselement 11 aus Metall gefertigt ist, beispielsweise als Druckgußteil, kann diese Zahnkupplung große Kräfte übertragen. Eine sichere Verankerung des handhebelseitigen Kupplungselements 11 im Werkstoff des Handhebels 1 erreicht man über die Verankerungselemente 13. Eine zusätzliche oder alternative Verankerung könnte man auch über einen aufgerauhten Zylinderaußenumfang oder dort angebrachte Verankerungselemente erzielen.After the fastening element 2 consists of a solid or hard material, preferably metal, and the hand lever-side coupling element 11 is also made of metal, for example as a die-cast part, this tooth coupling can transmit large forces. Secure anchoring of the hand lever-side coupling element 11 in the material of the hand lever 1 can be achieved via the anchoring elements 13. An additional or alternative anchoring could also be achieved via a roughened outer cylinder circumference or anchoring elements attached there.
