Definitions
- the invention relates to a pair of pliers, the handle legs of which are connected to one another via a joint and each form a jaw in the working area and have a handle area which is designed to be gripped and begins at the free end of the handle legs in the area of their opposite ends.
- Such pliers are used for pulling nails, pens or the like. as well as for cutting metal objects, e.g. Wires, used.
- a corresponding clamping force For the function of pulling, a corresponding clamping force must first be introduced via the two handle legs. The actual pulling process is then carried out by applying force perpendicular to the handle legs, which can take place in the direction of the rounded gripping jaws by a rolling process or perpendicularly to this by tilting the jaws on the drawing base. Often, rolling movements are also encountered in a plane on both sides away from the longitudinal axis of the object to be drawn within a pulling process. The required forces are then directed either against the wrist and middle of the finger or against the middle hand and end of the finger. With conventional Biting pliers apply both the clamping forces and the forces in connection with the pulling of grip legs which are rectangular or approximately rectangular in grip cross section and which are generally too small in size. Extreme pressure peaks in the palm and fingers are the result.
- pulling operations also occur parallel to the longitudinal axis of the pliers if, due to space restrictions or concern about the sensitive surface, no support options are possible on the drawing base.
- the invention has for its object to design a pair of pliers in such a way that its handling for the user is improved and thus more pleasant. In particular, the strain on the hand should be reduced.
- the grip area extends over about a hand's breadth, calculated from the end of the grip, and, seen in broadside view, is separated from the rest of the grip leg by an indentation in the outer contour of the grip leg, the outer sides of the grip leg in the grip area are approximately elliptical in broadside view, follow approximately the shape of an ellipse in cross section in the area of the coupling surface and are approximately elliptical in a narrow side view.
- the advantage of the invention is that the novel design of the hand side of the pliers, the two handle legs are adapted to the anatomy and anthropometry of the human hand.
- the starting point here is that the pliers are operated by hand gripping.
- a natural curvature through the hand skeleton is provided both on the wrist and in the area of the finger joint. This is taken into account by appropriate shaping of the handle legs.
- the two handle legs represent the pointed ends of an ellipse.
- the side flanks of the handle legs are also curved so that when the force is applied, they also correspond to the natural curvature of the palm at right angles to the closing movement.
- the grip area is clearly separated from the rest of the grip leg. This can be done, for example, by changing the width, or also by changing the thickness or, if appropriate, also by changing the arrangement of the handle legs. Combinations are also possible. This clear separation between the grip area and the rest of the area enables the user to automatically get into the grip area with his hand without looking.
- the leg distance in the area of the free end of the handle area is smaller than in the area of the opposite end of the handle area.
- the grip legs are offset parallel to one another at least in the grip area.
- the direction of the displacement is chosen such that the handle leg assigned to the four fingers is offset from the palm. This takes into account the fact that when the hand is closed, the finger limbs do not move directly in the direction of the counter bearing formed by the area of the carpal area.
- the width of the legs in the handle area is greater than in the remaining area of the handle legs. This also results in a clear separation of the grip area from the remaining area of the pliers.
- the pliers shown in Fig. 1 consists of two handle legs 11, 12 which are connected to each other via a joint 13. Due to the connection with the joint 13, the two legs 11, 12 can be pivoted about the axis formed by the joint 13. On one side, the upper side in FIG. 1, of the joint 13, the grip arms 11, 12 each form a jaw 14, 15. On the opposite side of the joint 13, the grip arms 11, 12 have a grip area 17, which differs from the free end 16 of the handle legs 11, 12 extends about a hand's width and is separated from the rest of the handle legs 11, 12 by an indentation 18.
- the opposing grip legs 11, 12 are designed such that their outer sides follow approximately the shape of an ellipse or an oval in the broadside view shown, which is indicated by the dash-dotted line 19.
- the large axis of the ellipse or oval 19 extends in the longitudinal direction of the handle legs and is approximately 100 mm, while the axis perpendicular to it is approximately 50 mm.
- the distance between the outer sides of the handle legs 11, 12 at the free The end 16 of the grip area 17 is slightly smaller than the distance between the outer sides of the grip legs 11, 12 in the area of the opposite end of the grip area 17.
- the outer periphery of the handle legs 11, 12 in the grip area 17 has approximately the shape of an elongated ellipse, the major axis of which is also approximately 100 mm , whose small axis has an amount of about 25 mm.
- Fig. 3 now shows a cross section approximately along line III-III in Fig. 1, i.e. approximately at the level of the small axis of the ellipse indicated by line 19.
- the outer surface 20 of the handle leg 11 and the outer surface 21 of the handle leg 12 are both in an ellipse 22 and 23, respectively, both ellipses being of the same design but being laterally displaced so that their major axes remain parallel to one another.
- the outer surfaces 20, 21 of the handle legs 11, 12 each lie in the ellipse in the region of their apex.
- the large axis of the ellipse 22 or 23 runs from the outside 20 of one grip leg 11 in the direction of the outside 21 of the other grip leg 12, which is not intended to be offset.
- the large axis 24 and the small axis 25 of the ellipse are shown in the narrow side view of the grip area 17.
- the dimensions are identical to the embodiment according to FIG. 2, the only difference from the embodiment according to FIGS. 1 to 3 is that the handle legs 11, 12 are not laterally offset in their handle area 17. 5, the two ellipses 22, 23 also coincide.
- the handling for the user of a pair of pliers with two handle legs and one jaw each, which are operatively connected via a joint, is optimized and improved by an ergonomic design of the handle legs.
- the advantage of this design of the hand side of the pliers is that the handle legs are optimally adapted to the anatomy and anthropometry of the human hand for all applications.
Abstract
Description
Die Erfindung betrifft eine Beißzange, deren über ein Gelenk miteinander verbundene Griffschenkel im Arbeitsbereich je einen Backen bilden und im Bereich ihrer gegenüberliegenden Enden einen zum Anfassen ausgebildeten, an dem freien Ende der Griffschenkel beginnenden Griffbereich aufweisen.The invention relates to a pair of pliers, the handle legs of which are connected to one another via a joint and each form a jaw in the working area and have a handle area which is designed to be gripped and begins at the free end of the handle legs in the area of their opposite ends.
Derartige Beißzangen werden sowohl zum Ziehen von Nägeln, Stiften o.dgl . als auch zum Ablängen von metallischen Gegenständen, wie z.B. Drähten, verwendet.Such pliers are used for pulling nails, pens or the like. as well as for cutting metal objects, e.g. Wires, used.
Für die Funktion des Ziehens muß zunächst eine entsprechende Klemmkraft über die beiden Griffschenkel eingeleitet werden. Der eigentliche Ziehvorgang erfolgt dann durch Krafteinleitung senkrecht zu den Griffschenkeln, wobei diese in Richtung der abgerundeten Greifbacken durch einen Abrollvorgang oder senkrecht dazu durch Verkanten der Backen auf dem Ziehgrund erfolgen kann. Häufig werden auch innerhalb eines Ziehvorgangs Abrollbewegungen in einer Ebene nach beiden Seiten weg von der Längsachse des zu ziehenden Gegenstands angetroffen. Die erforderlichen Kräfte richten sich dabei dann entweder gegen Handwurzel und Fingermittelglieder oder gegen Mittelhand und Fingerendglieder. Bei herkömmlichen Beißzangen werden sowohl die Klemmkräfte als auch die Kräfte im Zusammenhang mit dem Ziehen von im Griffquerschnitt rechteckigen oder angenähert rechteckigen Griffschenkeln mit in der Regel zu kleinen Abmessungen aufgebracht. Extreme Druckspitzen im Innenhand- und Fingerbereich sind dabei die Folge.For the function of pulling, a corresponding clamping force must first be introduced via the two handle legs. The actual pulling process is then carried out by applying force perpendicular to the handle legs, which can take place in the direction of the rounded gripping jaws by a rolling process or perpendicularly to this by tilting the jaws on the drawing base. Often, rolling movements are also encountered in a plane on both sides away from the longitudinal axis of the object to be drawn within a pulling process. The required forces are then directed either against the wrist and middle of the finger or against the middle hand and end of the finger. With conventional Biting pliers apply both the clamping forces and the forces in connection with the pulling of grip legs which are rectangular or approximately rectangular in grip cross section and which are generally too small in size. Extreme pressure peaks in the palm and fingers are the result.
Teilweise kommen auch Ziehvorgänge parallel zur Beißzangen-längsachse vor, wenn aufgrund von Platzrestriktionen oder aber der Sorge um den empfindlichen Untergrund keine Abstützmöglichkeiten am Ziehgrund möglich sind. Hier erfolgt eine rein reibschlüssige Kopplung für den Ziehvorgang an den in aller Regel parallel ausgerichteten Griffschenkeln, die für diese reibschlüssige Kopplung vollkommen ungeeignet sind.In some cases, pulling operations also occur parallel to the longitudinal axis of the pliers if, due to space restrictions or concern about the sensitive surface, no support options are possible on the drawing base. Here there is a purely frictional coupling for the pulling process on the generally parallel handle legs, which are completely unsuitable for this frictional coupling.
Ein weiterer Arbeitsvorgang mit der Beißzange betrifft das Ablängen von in aller Regel metallischen Werkstoffen. Hier muß die extrem hohe Schließkraft senkrecht zu den oben schon als ungeeignet definierten Griffschenkeln aufgebracht werden. Nachteile sind hier zum einen die zu geringen Querschnitte, die möglicherweise scharfkantige Form sowie die planparallele Ausbildung der Griffschenkel. Es ist weiterhin eine Zange für Sportler bekannt (US-A-26 18 058), bei der die Griffschenkel in ihrer Außenkontur leicht geschweift verlaufen und in Schmalseitenansicht gesehen oval ausgebildet sind. Die Zange ist wegen der zerklüfteten Außenseite ihrer Backen nicht als Beißzange geeignet.Another operation with the pliers concerns the cutting of generally metallic materials. Here, the extremely high closing force must be applied perpendicular to the handle legs already defined as unsuitable above. Disadvantages here are the insufficient cross-sections, the possibly sharp-edged shape and the plane-parallel design of the handle legs. A pair of pliers for athletes is also known (US Pat. No. 2,618,058), in which the grip legs are slightly curved in their outer contour and are oval in shape as seen in the narrow side view. The pliers are not suitable because of the jagged outside of their jaws.
Der Erfindung liegt die Aufgabe zugrunde, eine Beißzange derart zu gestalten, daß ihre Handhabung für den Benutzer verbessert und damit angenehmer wird. Insbesondere soll die Belastung der Hand vermindert werden.The invention has for its object to design a pair of pliers in such a way that its handling for the user is improved and thus more pleasant. In particular, the strain on the hand should be reduced.
Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, daß der Griffbereich sich über etwa eine Handbreit, vom Griffende aus gerechnet, erstreckt und in Breitseitenansicht gesehen durch eine Einbuchtung im Außenumriß der Griffschenkel von dem übrigen Bereich der Griffschenkel getrennt ist, wobei die Außenseiten der Griffschenkel im Griffbereich in Breitseitenansicht etwa ellipsenförmig angeordnet sind, im Querschnitt im Bereich der Kopplungsfläche zur Hand etwa der Form einer Ellipse folgen und in einer Schmalseitenansicht etwa ellipsenförmig ausgebildet sind.To achieve this object, it is provided according to the invention that the grip area extends over about a hand's breadth, calculated from the end of the grip, and, seen in broadside view, is separated from the rest of the grip leg by an indentation in the outer contour of the grip leg, the outer sides of the grip leg in the grip area are approximately elliptical in broadside view, follow approximately the shape of an ellipse in cross section in the area of the coupling surface and are approximately elliptical in a narrow side view.
Der Vorteil der Erfindung liegt darin, daß durch die neuartige Gestaltung der Handseite der Beißzange die beiden Griffschenkel an die Anatomie und Anthropometrie der menschlichen Hand angepaßt werden. Ausgangspunkt hierbei ist, daß die Beißzange in der Greifart Hand-Zufassung betätigt wird. Sowohl an der Handwurzel als auch im Bereich des Fingerverbunds ist eine natürliche Wölbung durch das Handskelett vorgesehen. Dieser wird durch eine entsprechende Formgebung der Griffschenkel Rechnung getragen. Im Querscnitt stellen die beiden Griffschenkel die spitzen Enden einer Ellipse dar. Die Seitenflanken der Griffschenkel sind ebenfalls geschweift geformt, um bei Krafteinleitung quer zur Schließbewegung ebenfalls der natürlichen Wölbung der Innenhand zu entsprechen. Außerdem entsteht eine günstige Kontaktfläche für den Handschluß für alle mit der Beißzange vorkommenden Tätigkeiten, wie z.B. Klemmen, Hebeln senkrecht zur Zangenachse und Ziehen längs der Zangenachse. Durch die Einbuchtung gleitet der Benutzer der Zange automatisch mit seiner Hand in den Griffbereich.The advantage of the invention is that the novel design of the hand side of the pliers, the two handle legs are adapted to the anatomy and anthropometry of the human hand. The starting point here is that the pliers are operated by hand gripping. A natural curvature through the hand skeleton is provided both on the wrist and in the area of the finger joint. This is taken into account by appropriate shaping of the handle legs. In cross-section, the two handle legs represent the pointed ends of an ellipse. The side flanks of the handle legs are also curved so that when the force is applied, they also correspond to the natural curvature of the palm at right angles to the closing movement. In addition, there is a favorable contact surface for the hand closure for all activities that occur with the pliers, such as clamping, levering perpendicular to the pliers axis and pulling along the pliers axis. Through the indentation, the user of the pliers automatically slides into the grip area with his hand.
In Weiterbildung kann vorgesehen sein, daß der Griffbereich von dem übrigen Bereich der Griffschenkel deutlich getrennt ist. Dies kann beispielsweise durch eine ºnderung der Breite, oder auch eine ºnderung der Dicke oder ggf. auch durch eine ºnderung der Anordnung der Griffschenkel geschehen. Es sind auch Kombinationen möglich. Diese deutliche Trennung zwischen Griffbereich und übrigem Bereich ermöglicht es, daß der Benutzer ohne hinzusehen mit seiner Hand automatisch in den Griffbereich gelangen kann.In a further development it can be provided that the grip area is clearly separated from the rest of the grip leg. This can be done, for example, by changing the width, or also by changing the thickness or, if appropriate, also by changing the arrangement of the handle legs. Combinations are also possible. This clear separation between the grip area and the rest of the area enables the user to automatically get into the grip area with his hand without looking.
Erfindungsgemäß kann in Weiterbildung vorgesehen sein, daß der Schenkelabstand im Bereich des freien Endes des Griffbereichs kleiner ist als im Bereich des entgegengesetzten Endes des Griffbereichs. Hierdurch wird eine nochmals verbesserte Anpassung der Geometrie der Zange an die Geometrie der Hand erreicht, da bei halbgeschlossener Hand der Handinnendurchmesser bei dem Zeigefinger größer ist als der gleiche Durchmesser bei dem kleinen Finger.According to the invention, it can be provided in a further development that the leg distance in the area of the free end of the handle area is smaller than in the area of the opposite end of the handle area. This results in a further improved adaptation of the geometry of the pliers to the geometry of the hand, since with a half-closed hand the inside diameter of the hand on the index finger is larger than the same diameter on the little finger.
In Weiterbildung kann vorgesehen sein, daß die Griffschenkel mindestens im Griffbereich parallel zueinander versetzt sind. Dabei ist die Richtung der Versetzung derart gewählt, daß der den vier Fingern zugeordnete Griffschenkel von dem Handteller weg versetzt ist. Hierdurch wird der Tatsache Rechnung getragen, daß beim Schließen der Hand sich die Fingerglieder nicht direkt in Richtung auf das durch den Handwurzelbereich gebildete Gegenlager bewegen.In a further development it can be provided that the grip legs are offset parallel to one another at least in the grip area. The direction of the displacement is chosen such that the handle leg assigned to the four fingers is offset from the palm. This takes into account the fact that when the hand is closed, the finger limbs do not move directly in the direction of the counter bearing formed by the area of the carpal area.
In weiterer Ausgestaltung kann vorgesehen sein, daß in Schmalseitenansicht gesehen die Breite der Schenkel im Griffbereich größer ist als im übrigen Bereich der Griffschenkel . Auch hierdurch wird eine deutliche Trennung des Griffbereichs von dem übrigen Bereich der Beißzange erreicht.In a further embodiment it can be provided that, seen in the narrow side view, the width of the legs in the handle area is greater than in the remaining area of the handle legs. This also results in a clear separation of the grip area from the remaining area of the pliers.

Die in Fig. 1 dargestellte Beißzange besteht aus zwei Griffschenkeln 11, 12, die über ein Gelenk 13 miteinander verbunden sind. Aufgrund der Verbindung mit dem Gelenk 13 sind die beiden Schenkel 11, 12 um die durch das Gelenk 13 gebildete Achse verschwenkbar. Auf der einen Seite, der in Fig. 1 oberen Seite, des Gelenks 13 bilden die Griffschenkel 11, 12 je einen Backen 14, 15. Auf der gegenüberliegenden Seite des Gelenks 13 weisen die Griffschenkel 11, 12 einen Griffbereich 17 auf, der sich von dem freien Ende 16 der Griffschenkel 11, 12 über etwa eine Handbreite erstreckt und von dem übrigen Bereich der Griffschenkel 11, 12 durch eine Einbuchtung 18 getrennt ist. Im Griffbereich 17 sind die sich gegenüberliegenden Griffschenkel 11, 12 derart ausgebildet, daß ihre Außenseiten in der dargestellten Breitseitenansicht etwa der Form einer Ellipse oder eines Ovals folgen, das durch die strichpunktierte Linie 19 angedeutet ist. Die große Achse der Ellipse bzw. des Ovals 19 verläuft in Längsrichtung der Griffschenkel und beträgt etwa 100 mm, während die senkrecht dazu stehende Achse etwa 50 mm beträgt. Der Abstand der Außenseiten der Griffschenkel 11, 12 am freien Ende 16 des Griffbereiches 17 ist etwas kleiner als der Abstand der Außenseiten der Griffschenkel 11, 12 im Bereich des gegenüberliegenden Endes des Griffbereichs 17.The pliers shown in Fig. 1 consists of two
Aus der in Fig. 2 dargestellten Schmalseitenansicht der Beißzange in Fig. 1 von rechts ergibt sich, daß auch aus dieser Ansicht der Außenumfang der Griffschenkel 11, 12 im Griffbereich 17 etwa die Form einer langgestreckten Ellipse aufweist, deren große Achse ebenfalls etwa 100 mm beträgt, deren kleine Achse aber einen Betrag von etwa 25 mm aufweist.From the narrow side view of the pliers in Fig. 1 shown in Fig. 1 from the right it follows that from this view, the outer periphery of the
Fig. 3 zeigt nun einen Querschnitt etwa längs Linie III-III in Fig. 1, d.h. etwa in Höhe der kleinen Achse der durch die Linie 19 angedeuteten Ellipse. Die Außenfläche 20 des Griffschenkels 11 und die Außenfläche 21 des Griffschenkels 12 liegen beide in einer Ellipse 22 bzw. 23, wobei beide Ellipsen gleich ausgebildet, jedoch seitlich verschoben sind, so daß ihre großen Achsen zueinander parallel bleiben. Die Außenflächen 20, 21 der Griffschenkel 11, 12 liegen jeweils in der Ellipse im Bereich von deren Scheitel. Mit anderen Worten verläuft die große Achse der Ellipse 22 bzw. 23 von der Außenseite 20 des einen Griffschenkels 11 in Richtung auf die Außenseite 21 des anderen unversetzt gedachten Griffschenkels 12.Fig. 3 now shows a cross section approximately along line III-III in Fig. 1, i.e. approximately at the level of the small axis of the ellipse indicated by
Bei der Ausführungsform nach Fig. 4 ist in die Schmalseitenansicht des Griffbereichs 17 die große Achse 24 und die kleine Achse 25 der Ellipse eingezeichnet. Die Abmessungen sind identisch wie bei der Ausführungsform nach Fig. 2, der einzige Unterschied zu der Ausführungsform nach den Fig. 1 bis 3 besteht darin, daß die Griffschenkel 11, 12 in ihrem Griffbereich 17 nicht seitlich versetzt sind. Dementsprechend fallen bei dem Schnitt nach Fig. 5 auch die beiden Ellipsen 22, 23 zusammen.In the embodiment according to FIG. 4, the
Durch die in den Ansprüchen, der Beschreibung und der Zeichnung dargestellten Maßnahmen wird die Handhabung der Zange sowohl im Hinblick auf die Zugkräfte in Richtung zu der Längsachse der Zange als auch für die Hebelkräfte quer zur Zangenlängsachse verbessert.Due to the measures shown in the claims, the description and the drawing, the handling of the pliers is improved both with regard to the tensile forces in the direction of the longitudinal axis of the pliers and for the lever forces transverse to the longitudinal axis of the pliers.
Die Handhabung für den Benutzer einer Beißzange mit zwei Griffschenkeln und je einem Backen, die über ein Gelenk in Wirkverbindung stehen, wird durch eine ergonomische Gestaltung der Griffschenkel optimiert und verbessert. Dies wird dadurch erreicht, daß sich die Griffschenkel zueinander am unteren Ende ellipsenförmig gegenüberstehen, daß die Griffschenkel längs der Kopplungsflächen zur Hand und zu den Fingern ellipsenförmig ausgebildet sind und daß die Griffschenkel im Bereich der Kopplungsfläche zur Hand einen ellipsenförmigen Querschnitt aufweisen. Der Vorteil dieser Gestaltung der Handseite der Beißzange liegt darin, daß für alle Anwendungsfälle die Griffschenkel in optimaler Form an die Anatomie und Anthropometrie der menschlichen Hand angepaßt sind.The handling for the user of a pair of pliers with two handle legs and one jaw each, which are operatively connected via a joint, is optimized and improved by an ergonomic design of the handle legs. This is achieved in that the grip arms are elliptical at the lower end, that the grip arms are elliptical along the coupling surfaces at hand and to the fingers and that the grip arms have an elliptical cross-section in the area of the coupling surface. The advantage of this design of the hand side of the pliers is that the handle legs are optimally adapted to the anatomy and anthropometry of the human hand for all applications.
