Definitions
- the Frfindung relates to a hand lever with fixing element, in particular for a spindle, od axis.
- the Eandhebel and made of hard material, preferably metal-made fixing member in the longitudinal direction of the lever pivot axis by means of two Kup lung selenium duck p axially coupled in the direction of rotation are.
- hand levers of this type are preferably used wherever the handle of the lever is in one or the other in relation to the spindle, axis or the like before the start of the rotation, or possibly after a certain partial rotation wants to bring it back to a predetermined starting position.
- a preferred area of application are clamping levers as used in technology, especially in connection with machine tools, or clamping devices for holding workpieces that are to be machined on such machine tools.
- the object of the invention is therefore to develop a hand lever with Pefestigunas element of the type mentioned so that the hand lever can be made of other, in particular lighter material than metal and still not or at least not the load when transmitting a torque from the hand lever to the fastener is much less than with a hand lever made of metal.
- the hand lever in the case of a hand lever with a fastening element of the type described in the introduction, is made of a softer material than the Pefestigunos element, in particular made of plastics and the hand lever-side coupling element made of hard material, in particular metal, as is rotatably anchored in the material of the wall lever. Because both the hand lever-side and the fastening element-side coupling element now each consist of hard material, in particular metal, the torque can be transmitted at the same level at this point as with a netall hand lever. The load capacity is now only limited by the non-rotatable connection between the material of the hand lever and the hand lever coupling element.
- the hand lever-side coupling element is formed as a ring, preferably made of die-casting, which carries coupling elements distributed on the circumference on its side assigned to the fastening element and anchoring elements on its opposite side for anchoring in the material of the hand lever.
- the shape and size of the latter also depend not least on the material of the hand lever and the type of attachment of the hand lever-side coupling element in mate rial of the hand lever.
- the hand lever-side coupling element is expediently extrusion-coated with the plastic of the hand lever.
- the coupling elements are kept free, so that a metal-to-metal coupling is easily possible.
- the anchoring elements of the coupling element on the hand lever side consist in particular of pins, warts or the like, which protrude evenly on the outer circumference.
- “on the outer circumference” does not mean that the pins or the like have to protrude in the radial direction; rather, in the exemplary embodiment of the invention, protrusion in the axial direction is provided from the ring surface in question.
- the coupling elements of the coupling element on the hand lever side are formed by the teeth of a ring gear with internal teeth.
- This ring gear is also expediently assigned to the outer region of the annular coupling element in order to obtain a maximum size.
- AuPerden requires the tooth shape that there is a corresponding counter-toothing with the same or similar tooth shape on the fastening element. The teeth of the hand lever or the coupling element on the lever side then grip between the teeth of the fastening element.
- a further embodiment of the invention provides that the Kupplunos counter-members of the fastener element-side coupling element are formed by the teeth of a pinion attached to the inner end of the fastening element, in particular molded on, with external teeth, the teeth of the coupling members and coupling counter-members being in and out in the tooth longitudinal direction can be disengaged and the clutch is axially spring-loaded in the locking direction. Due to the spring load, the hand lever and the fastening element are always coupled non-rotatably, so that when the fastening element is connected to a spindle, axis or the like in a rotationally fixed manner, rotating the hand lever also causes the spindle or the like to rotate.
- the hand lever 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 resistance, for example upwards in front of the fastening element, against the resistance, and rotated by the intended angle of rotation.
- the toothing only allows a gradual displacement. However, this is without disadvantage in most applications.
- a compression spring designed as a compression spring for the coupling of the hand lever and fastening element be supported at one end on the upper side of the hand lever-side coupling element and at the other end on an outer collar of a support member of the fastening element which axially penetrates this coupling element.
- this support member can be, for example, a screw, the underside of the head of which forms the support surface for the bridge spring which is advantageously designed as a helical compression spring.
- the fixing element is designed as a cup or a pot-shaped element with an inner pot base, which is mounted in a sleeve-shaped extension of the hand lever so as to be longitudinally displaceable and rotatable.
- a central nut thread can be provided in the base of the pot for tightening 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.
- 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 was reinforced by an intermediate wall 3. As shown in particular in FIG. 1, the fastening element 2 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 given by a conical 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.
- 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.
- the fastener 2 carries in particular evenly distributed on the circumference, the anchoring ir plastic material serving pin or wart-shaped anchoring elements 13.
- a ring gear 14 is formed nit nit 15 teeth. The latter thus extends p a-rallel to the axis 16 a with the mounting member 2 to be connected to spindle 17, 06 or the like.
- spindle Pefest Trentselement 2 is screwed with its parent thread 4.
- a coupling element 18 on the fastening element side is integrally formed on the plugged-in inner end of the fastening element 2. 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, that is to say via these two parts the gear lever and the fastening element 2 are coupled to one another.
- To disengage pull the hand lever 1 in the direction of the arrow 20 while the spindle 17 is held tight, whereby the spring 9 is compressed, if necessary, up 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.
- the coupling becomes 1 when the hand lever is released indented due to the tension of the spring 9.
- the fastening element 2 consists of a solid or hard material, preferably metal
- 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 is 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.

Description
Die Frfindung bezieht sich auf einen Handhebel mit Befestigungselement, insbesondere für eine Spindel, Achse od. dgl., wobei der Eandhebel und das aus hartem Werkstoff, vorzugsweise Metall, gefertigte Befestigungselement in Längsrichtung der Hebel-Drehachse mittels zweier Kupplungselenente in Drehrichtung axial gekuppelt sind. Für derartige Handhebel gibt es die verschiedensten Anwendungsgebiete, und man setzt sie bevorzugterweise überall dort ein, wo man den Griff des Hebels vor Beginn der Drehung, oder evtl. auch nach einer gewissen Teildrehung, gegenüber der Spindel, Achse od. dgl. in eine bzw. wieder in eine vorgegebene Ausgangsposition bringen möchte. Ein bevorzugtes Anwendungsgebiet sind Klemmhebel, vie man sie in der Technik, insbesondere in Verbindung mit werkzeugmaschinen, verwendet, bzw. Klemmvorrichtungen zur Festhalter von werkstücken, die auf solchen Werkzeugmaschinen bearbeitet werden sollen.The Frfindung relates to a hand lever with fixing element, in particular for a spindle, od axis. The like., The Eandhebel and made of hard material, preferably metal-made fixing member in the longitudinal direction of the lever pivot axis by means of two Kup lung selenium duck p axially coupled in the direction of rotation are. There are various fields of application for hand levers of this type, and they are preferably used wherever the handle of the lever is in one or the other in relation to the spindle, axis or the like before the start of the rotation, or possibly after a certain partial rotation wants to bring it back to a predetermined starting position. A preferred area of application are clamping levers as used in technology, especially in connection with machine tools, or clamping devices for holding workpieces that are to be machined on such machine tools.
Bislang hat man derartige Handbebel aus Metall gefertigt. Aus verschiedenen Gründen möchte man auch auf dem Gebiet der Handhebel den Kunststoff vor dem Metall den Vorzug ceben. Kunststoff hat in der normalerweise verwendeten Form keine so große Härte und Belastbarkeit wie Metall. Infolgedessen ist die Belastbarkeit bei einen aus Kunststoff hergestellten Handhebel normalerweise geringer als diejenige eines metallenen Handhebels. Für das Befestigungselement bietet sich die Verwendung von Kunststoff aus verschiedenen Gründen nicht an.So far, such a hand lever has been made of metal. For various reasons, one would also like to give preference to plastic over metal in the area of hand levers. Plastic, in the form normally used, is not as hard and resilient as metal. As a result, the load capacity of a hand lever made of plastic is usually lower than that of a metal hand lever. For various reasons, the use of plastic is not suitable for the fastening element.
Die Aufgabe der Erfindung besteht infolgedessen darin, einen Handhebel mit Pefestigunaselement der eingangs genannten Art so weiterzubilden, daß der Handhebel aus anderem, insbesondere leichterer Werkstoff als Metall gefertigt weren kann und trotzdem die Belastung beim übertragen eines Drehmoments vom Handhebel auf das Befestigungselement nicht oder zunindest nicht wesentlich geringer ist, als bei einem aus Metall gefertigten Handhebel.The object of the invention is therefore to develop a hand lever with Pefestigunas element of the type mentioned so that the hand lever can be made of other, in particular lighter material than metal and still not or at least not the load when transmitting a torque from the hand lever to the fastener is much less than with a hand lever made of metal.
Zur Lösung dieser Aufgabe wird erfindungsgemäß vorgeschlagen, daß bei einen Handhebel mit Pefestigungselement der eingangs beschriebenen Art der Handhebel aus einem weicheren Werkstoff als das Pefestigunoselement, insbesondere aus Kunststoffe gefertigt ist und das handhebelseitige Kupplungselement aus hartem Werkstoff, insbesondere Metall, besteht, scwie drehfest in Werkstoff des Wandhebels verankert ist. Weil nunmehr sowohl das handhebelseitige als auch das befestigungselementseitige Kupplungselement jeweils aus harten Werkstoff, insbesondere aus Metall, bestehen, kann an dieser Stelle das Drehnoment in gleicher Höhe übertragen werden wie bei einen netallenen Handhebel. Der Belastbarkeit sind demnack nur noch an der drehfesten Verbindung zwischen den Werkstoff des Handhebels und dem handhebelseitigen Kupplungselement Grenzen gesetzt. Wenn dort die Belastbarkeit derjenigen des Materials im Bereich der Kupplungselemente entspricht, so kann dieser Handhebel einen metallenen vollwertig ersetzen. Andererseits ergeben sich aber die üblichen Vorteile der Kunststofffertigung, insbesondere das geringe Gewicht und der günstige Preis. Rs entfallen auch Oberflächenveredelung und gegebenenfalls -bearbeitung.To achieve this object, it is proposed according to the invention that in the case of a hand lever with a fastening element of the type described in the introduction, the hand lever is made of a softer material than the Pefestigunos element, in particular made of plastics and the hand lever-side coupling element made of hard material, in particular metal, as is rotatably anchored in the material of the wall lever. Because both the hand lever-side and the fastening element-side coupling element now each consist of hard material, in particular metal, the torque can be transmitted at the same level at this point as with a netall hand lever. The load capacity is now only limited by the non-rotatable connection between the material of the hand lever and the hand lever coupling element. If the load capacity there corresponds to that of the material in the area of the coupling elements, this hand lever can fully replace a metal one. On the other hand, there are the usual advantages of plastic production, especially the low weight and the low price. Rs also omit surface finishing and, if necessary, processing.
In Weiterbildung der Erfindung wird vorgeschlagen, daß das handhebelseitige Kupplungselement als Ring, vorzugsweise aus Druckguß geformt ist, der an seiner dem Befestigungselement zugeordneten Seite am Umfang verteilte Kupplungselemente und an seiner gegenüberliegenden Seite Verankerungselerente für die Verankerung in Werkstoff des Handhebels trägt. Form und Größe der letzteren hängen nicht zuletzt auch vom Material des Handhebels sowie der Befestigungsart des handhebelseitigen Kupplungselements in Material des Handhebels ab. Zwecknäßigerweise wird das handhebelseitige Kupplungselement mit dem Kunststoff des Handhebels umspritzt. Dabei werden selbstverständlich die Kupplungselemente freigehalten, damit eine Kupplung Metall auf Metall ohne weiteres möglich ist.In a further development of the invention, it is proposed that the hand lever-side coupling element is formed as a ring, preferably made of die-casting, which carries coupling elements distributed on the circumference on its side assigned to the fastening element and anchoring elements on its opposite side for anchoring in the material of the hand lever. The shape and size of the latter also depend not least on the material of the hand lever and the type of attachment of the hand lever-side coupling element in mate rial of the hand lever. The hand lever-side coupling element is expediently extrusion-coated with the plastic of the hand lever. Of course, the coupling elements are kept free, so that a metal-to-metal coupling is easily possible.
In weiterer Ausgestaltung der Erfindung wird vorgeschlagen, daß die VerankerungseleMente des handhebelseitigen Kuoplungselements aus insbesondere 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, vielnehr 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 in particular 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 the exemplary embodiment of the invention, protrusion in the axial direction is provided from the ring surface in question.
Die Kupplungselemente des handhebelseitigen Kupplungselements sind gemäß einer weiteren Variante der Erfindung durch die Zähne eines Zahnkranzes mit Innenverzahnung gebildet. Auch dieser Zahnkranz wird zweckmäßigerweise dem Außenbereich des ringförmigen Kupplungselements zugeordnet, um eine maximale Größe zu erhalten. AuPerden setzt die Zahnform voraus, daß am Befestigungselement eine entsprechende Gegenverzahnung mit gleicher oder ähnlicher Zahnform vorhanden ist. Dabei greifen dann die Zähne des Handhebels bzw. des handhebelseitigen Kupplungselements zwischen die Zähne des Pefestigungselements.According to a further variant of the invention, the coupling elements of the coupling element on the hand lever side are formed by the teeth of a ring gear with internal teeth. This ring gear is also expediently assigned to the outer region of the annular coupling element in order to obtain a maximum size. AuPerden requires the tooth shape that there is a corresponding counter-toothing with the same or similar tooth shape on the fastening element. The teeth of the hand lever or the coupling element on the lever side then grip between the teeth of the fastening element.
Infolgedessen sieht eine weitere Ausbildung der Erfindung vor, daß die Kupplunos-Gegenolieder des befestigungselementseitiger Kupplungselements durch die Zähne eines am inneren Ende des Refestigungselements 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 Finrastrichtung federbelastet ist. Aufgrund der Federbelastung sind der Handhebel und das Befestigungselement stets drehfest riteinander gekuppelt, so daß bei drehfester Verbindung des Eefestigungselements 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 beispielsweise nach oben hin vor Refestigungselement ab und dreht ihn um den vorgesehenen Drehwinkel. Die Verzahnung läßt allerdings nur ein stufenweises Versetzen zu. Dies ist jedoch in den meisten Anwendungsfällen ohne Nachteil.As a result, a further embodiment of the invention provides that the Kupplunos counter-members of the fastener element-side coupling element are formed by the teeth of a pinion attached to the inner end of the fastening element, in particular molded on, with external teeth, the teeth of the coupling members and coupling counter-members being in and out in the tooth longitudinal direction can be disengaged and the clutch is axially spring-loaded in the locking direction. Due to the spring load, the hand lever and the fastening element are always coupled non-rotatably, so that when the fastening element is connected to a spindle, axis or the like in a rotationally fixed manner, rotating the hand lever also causes the spindle or the like to rotate. 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 resistance, for example upwards in front of the fastening element, against the resistance, and rotated by the intended angle of rotation. The toothing, however, only allows a gradual displacement. However, this is without disadvantage in most applications.
Gemäß einer bevorzugten Ausführungsform der Erfindung wird vorgeschlagen, daß sich eine als Druckfeder ausgebildete Belastungsfeder für die Kupplung von Handhebel und Befestigungselement einenends an der Oberseite des handhebelseitigen Kupplungselements und andernends an einem Außenbund eines dieses Kupplungselement axial durchsetzenden Stützglieds des Befestigungselements abstützt. Fei diesen Stützglied kann es sich beispielsweise um eine Schraube handeln, deren Kopfunterseite die Stützfläche für die vorteilhafter als Schraubendruckfeder ausgebildete Bruckfeder bildet. Dadurch läßt sich die Einheit in besonders einfacher Weise montieren. beispielsweisedurch Elocklage der Schraubendruckfeder kann man die axiale Relativbewegung zwischen Handhebel und Befestigungselement begrenzen.According to a preferred embodiment of the invention, it is proposed that a compression spring designed as a compression spring for the coupling of the hand lever and fastening element be supported at one end on the upper side of the hand lever-side coupling element and at the other end on an outer collar of a support member of the fastening element which axially penetrates this coupling element. Fei this support member can be, for example, a screw, the underside of the head of which forms the support surface for the bridge spring which is advantageously designed as a helical compression spring. This allows the unit to be assembled in a particularly simple manner. for example, by the elastic position of the helical compression spring, the axial relative movement between the hand lever and the fastening element can be limited.
Fine Weiterbildung der Erfindung sieht vor, daß das Refestigungselement als Fülse oder topfförmiges Blement mit innenliegenden Topfboden ausgebildet ist, das längsverschieb-und drehbar in einem hülsenförmigen Ansatz des Handhebels gelagert ist. Pei Verwendung einer Schraube als Stützglied kann im Topfboden ein zentrisches Muttergewinde zum Bindrehen 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 fixing element is designed as a cup or a pot-shaped element with an inner pot base, which is mounted in a sleeve-shaped extension of the hand lever so as to be longitudinally displaceable and rotatable. When using a screw as a support member, a central nut thread can be provided in the base of the pot for tightening 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.

Der Handhebel 1 besteht aus einem Material vergleichsweise geringer Härte, insbesondere aus Kunststoff. An seinem dem Befestigungselement 2 zugekehrten 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 wurde durch eine Zwischenwand 3 verstärkt. Das Refestigungselement 2 hat, wie insbesondere die Fig. 1 zeigt, eine in wesentlichen hülsenförmige Gestalt. An seinen 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 ungaben. 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
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 wegweisenden Seite trägt das Befestigungselement 2 insbesondere gleichmäßig am Umfang verteilte, der Verankerung ir Kunststoffnaterial dienende zapfen- oder warzenförmige verankerungselemente 13. An der gegenüberliegenden Unterseite des Befestigungselements 2 ist ein Zahnkranz 14 nit nach innen weisenden Zähnen 15 angeformt. Letztere erstreckt sich demnach pa-rallel zur Achse 16 einer mit dem Befestigungselement 2 zu verbindenden Spindel 17 06. dgl. Auf das nach oben ragende Spindelende ist das Pefestigungselement 2 mit seinem Muttergewinde 4 aufgeschraubt.The in Figs. 3 and 4, hand lever-
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 Eandhebel 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 zusammengedrückt wird. Nachfolgend kann man den Handhebel 1 senkrecht zur Bildebene gegenüber den Befestigungselement 2 um einen vorgegebener Winkel drehen.
