Abstract

Pliers contain on both pliers limbs a pliers handle, which is injection moulded round the corresponding metal pliers limbs. Injection moulding on takes place at a point located at the handle end facing the pliers joint. As a result the entire surface of the handle, which can be gripped by a user, remains free from surface disturbances and interference. A raised marking can be applied to the mould-on point.

Description

Die Erfindung betrifft einen Griff nach dem Oberbegriff des Anspruchs 1. Es ist bekannt, bei bestimmten Zangen, die aus Metall bestehen, die Griffe mit einer aus Kunststoff bestehenden Umhüllung zu versehen. Diese soll das Handhaben der Zange erleichtern.The invention relates to a handle according to the preamble of claim 1. It is known that certain pliers made of metal the handles with a plastic cover to provide. This should make handling of the pliers easier.

Bei einer bekannten Zange dieser Art (FR-A-2215294) ist die Griffschale als getrenntes aus Kunststoff bestehendes Bauteil hergestellt, das nachträglich auf den Zangenschenkel aufgeschoben und mit diesem verbunden wird.In a known pliers of this type (FR-A-2215294) Handle shell as a separate component made of plastic manufactured, which subsequently pushed onto the pliers legs and connected to it.

Auch bei einem weiteren zangenförmigen Handwerkszeug (DE-A-30 19 734 ) wird die Griffschale nach ihrer Fertigstellung auf den Griffschenkel aufgezogen.Also with another pliers-shaped hand tool (DE-A-30 19 734) the handle shell is finished mounted on the handle leg.

Ebenfalls bekannt sind Zangen, bei denen die Griffe aus einem relativ harten Material aus Kunststoff gespritzt werden.Pliers are also known, in which the handles consist of a relatively hard plastic material.

Es ist bereits aus der DE-U-29705522 ein Griff für ein zweischenkliges Werkzeug gemäß dem Oberbegriff des Anspruchs 1 bekannt, der um ein Ende eines Werkzeugschenkels herum angeordnet und aus Kunststoff gespritzt ist. Dabei ist die Angießstelle an dem dem Gelenk abgewandten freien Ende angeordnet.It is already known from DE-U-29705522 a handle for a two-legged tool according to the preamble of claim 1 arranged around one end of a tool leg and out Plastic is injected. The sprue is at the joint arranged away free end.

Weiterhin ist ein Zangenhandgriff bekannt (DE-U- 9112630), der aus zwei Kunststoffschalen unterschiedlicher Härte aufgebaut ist. Die äußere Schale besteht aus weicherem Material.Furthermore, a plier handle is known (DE-U-9112630) that two plastic shells of different hardness is built. The outer Shell is made of softer material.

Der Erfindung liegt die Aufgabe zugrunde, einen Griff der gettungsbildenden Bauart für ein zweischenkliges Werkzeug in ergonomischer Hinsicht weiter zu entwickeln.The invention has for its object a handle of the delineating type for two-legged tool further ergonomically develop.

Zur Lösung dieser Aufgabe schlägt die Erfindung einen Griff mit den Merkmalen des Anspruchs 1 vor. Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche 2-11, deren Wortlaut ebenso wie der Wortlaut der Zusammenfassung durch Bezugnahme zum Inhalt der Beschreibung gemacht wird. To achieve this object, the invention proposes a handle with the features of claim 1 in front. Developments of the invention are Subject of dependent claims 2-11, their wording as well as the wording of the summary by reference to Content of the description is made.

Zangen werden zu verschiedenen Tätigkeiten verwendet. Sie dienen nicht nur dazu, Gegenstände zu halten, sondern auch dazu, die gehaltenen Gegenstände zu bewegen, umzuorientieren oder auch zu tragen. Während bei den bekannten Zangengriffen, die aus Kunststoff gespritzt sind, die Angießstelle am freien Ende des Griffs angeordnet ist, werden diese Stellen jetzt an die gegenüberliegenden Enden der Griffe verlegt. Wenn ein Benutzer mit der Zange schiebt, so kann das Ende der Zange an seinem Handballen oder Handteller anliegen. Dadurch, dass die Angussstelle jetzt nicht mehr an dieser Stelle liegt, verbessert sich die Benutzung der Zange wesentlich.Pliers are used for various activities. she serve not only to hold objects, but also to move the held objects to reorient or to wear. While with the known pliers handles, molded from plastic, the sprue at the free Arranged end of the handle, these places are now on relocated the opposite ends of the handles. If a user with the pliers, so the end of the pliers can his palm or palm. Because the Gating point is no longer at this point, improved the use of the pliers is essential.

Auch die Ausbildung der Außenseite der Griffe mit einer weicheren Oberfläche verbessert die Handhabung. Die etwas weichere Oberfläche verbessert sowohl die Griffigkeit als auch die Druckbelastung der Hand.Also the formation of the outside of the handles with a softer Surface improves handling. The slightly softer Surface improves both grip and the pressure load on the hand.

Was hier an dem Beispiel einer Zange ausgeführt wurde, gilt in gleicher oder ähnlicher Weise auch für andere zweischenklige Werkzeuge, beispielsweise Scheren. Gerade bei Blechscheren, Teppichscheren oder Astscheren müssen häufig hohe Kräfte aufgewandt werden. Auch hier ist es sinnvoll, die von der Erfindung vorgeschlagenen Merkmale durchzuführen.What was done here using the example of pliers applies in the same or similar way for other two-legged Tools, such as scissors. Especially with tin snips, Carpet shears or pruning shears often need high forces be used. Here, too, it makes sense to use the Perform features proposed by the invention.

In Weiterbildung der Erfindung kann vorgesehen sein, dass die dem jeweils anderen Griff zugewandte Innenseite des Griffs eine härtere Oberfläche aufweist als der Bereich mit der weicheren Oberfläche. An diesen Stellen greift der Benutzer allenfalls an, um das Werkzeug zu öffnen, also nur mit geringer Kraft, so dass hier eine weichere Oberfläche keine besondere Vorteile mit sich bringt. In a development of the invention it can be provided that the the inside of the handle facing the other handle has a harder surface than the area with the softer surface. The user intervenes at these points at most to open the tool, so only with a small amount Strength, so here a softer surface is not a special one Brings advantages.

In Weiterbildung der Erfindung kann vorgesehen sein, dass die Bereiche unterschiedlicher Oberflächenhärte auch unterschiedliche Farben aufweisen.In a development of the invention it can be provided that the Areas of different surface hardness also different Show colors.

Erfindungsgemäß kann es ausreichen, den Bereich mit der weicheren Oberfläche nur an den Teilen des Handgriffs vorzusehen, wo die Hand des Benutzers besonders belastet ist. Erfindungsgemäß kann jedoch auch mit Vorteil vorgesehen werden, dass der Bereich mit der weicheren Oberfläche in Längsrichtung des Griffs von dem dem Gelenk zugeordneten Griffende bis zu dem freien Ende des Griffs reicht. Das dem Gelenk zugeordnete Griffende kann beispielsweise eine Verbreiterung des Querschnitts aufweisen, die ein deutliches Ende desjenigen Teiles des Griffs markiert, an dem der Benutzer angreift, auch wenn der aus Kunststoff bestehende umspritzte Teil des Zangenschenkels noch etwas weiter reicht. Diese Verbreiterung dient in der Regel als Abgleitschutz und wird häufig als Griffkopf bezeichnet.According to the invention, the area with the softer area may be sufficient Surface to be provided only on the parts of the handle where the user's hand is particularly stressed. According to the invention can however also be advantageously provided that the area with the softer surface lengthways of the handle from the handle end assigned to the joint to the free end of the handle. The one assigned to the joint For example, the end of the handle can be widened Have cross-section that has a clear end of that Marked part of the handle on which the user attacks, even if the molded part of the plastic Pliers legs extend a little further. This broadening usually serves as anti-slip protection and is often used as Handle head labeled.

Weiterhin kann vorgesehen sein, dass der Bereich mit der weicheren Oberfläche auch die Flachseiten des Griffes mindestens teilweise mit einschließt.It can further be provided that the area with the softer surface also the flat sides of the handle at least partially includes.

Die Bereiche mit der unterschiedlichen Oberflächenhärte können dadurch hergestellt werden, dass auf den Bereich des Griffs, der die geringere Oberflächenhärte aufweisen soll, in einem zweiten Arbeitsgang eine Beschichtung aus weicherem Material aufgebracht wird. Die Beschichtung kann relativ dünn sein.The areas with the different surface hardness can be manufactured by focusing on the area of Handle, which should have the lower surface hardness, in a second step, a coating of softer Material is applied. The coating can be relatively thin his.

In Weiterbildung der Erfindung kann vorgesehen sein, dass die Angießstelle, die auch bei sorgfältigster Bearbeitung immer noch sichtbar sein wird, dazu verwendet wird, eine Markierung anzubringen, bei der es sich insbesondere um eine erhabene Markierung handeln kann. Diese kann zur Kennzeichnung der Art der Zange, des Herstellers oder dgl. verwendet werden. Sie ist insbesondere so ausgebildet, dass sie auch nach langem Gebrauch der Zange nicht zerstört wird, wie dies bei einem Aufdrucken der Fall wäre.In a development of the invention it can be provided that the Pouring point that always with the most careful processing will still be visible, is used to mark it to attach, which is in particular a sublime Mark can act. This can be used to identify Art the pliers, the manufacturer or the like. she is especially designed so that even after a long time Use of the pliers is not destroyed, as is the case with one Would be the case.

In Weiterbildung kann vorgesehen sein, dass der Griff des zweischenkligen Werkzeugs in dem Oberflächenbereich mit der weicheren Oberfläche eine Markierung aufweisen kann, die dadurch gebildet ist, dass dort Teile des Kerns des Griffs, der aus härterem Material besteht, als erhabene Teile stehen bleiben, um die das weichere Material herumgespritzt ist. Die Oberfläche dieser erhabenen Teile verläuft bündig mit der weicheren Oberfläche. Dadurch entsteht eine bleibene Markierung, die auch nach langem Gebrauch des Werkzeugs erhalten bleibt.In a further development it can be provided that the handle of the two-legged tool in the surface area with the softer surface can have a mark that is formed in that parts of the core of the handle, which is made of harder material than the raised parts remain around which the softer material is splashed. The The surface of these raised parts is flush with the softer surface. This creates a permanent mark, which are preserved even after long use of the tool remains.

In Weiterbildung der Erfindung kann vorgesehen sein, daß die Beschichtung mit dem weicheren Material durch Anspritzen von dem dem Gelenk zugeordneten Ende des Griffs her erfolgt, wobei vorzugsweise das Anspritzen durch eine Lücke in dem Griffkopf hindurch erfolgen kann. Diese Lücke kann beispielsweise an der dem jeweils anderen Griff abgewandten Außenseite des entsprechenden Griffschenkels erfolgen. An dieser Stelle greift ein Benutzer im Normalfall nicht an, so dass diese Lücke, die ja durch das weichere Material dann ausgefüllt wird, nicht störend wirkt. Insbesondere ist sie jedoch an den Flachseiten der Zange angeordnet.In a further development of the invention it can be provided that the Coating with the softer material by spraying on the end of the handle associated with the joint takes place, wherein preferably spraying through a gap in the Handle head can be done. This gap can, for example on the outside facing away from the other handle of the corresponding handle leg. At this point normally does not attack a user, so this Gap, which is then filled by the softer material will not be distracting. In particular, however, it is on Flat sides of the pliers arranged.

Erfindungsgemäß kann vorgesehen sein, dass an dem dem Gelenk zugeordneten Ende des Griffs eine Markierung angespritzt wird, die erhaben oder vertieft ausgebildet sein kann. According to the invention it can be provided that on the joint assigned a mark molded onto the associated end of the handle will be raised or deepened.

In den Figuren wird als Beispiel für ein zweischenkliges Werkzeug eine Zange verwendet. Alles, was hier im Hinblick auf den Griff einer Zange gesagt wird, gilt ebenfalls für andere zweischenklige Werkzeuge, wie beispielsweise Blechscheren oder dergleichen.In the figures is an example of a two-legged Tool uses pliers. Everything in view here on the handle of a pair of pliers also applies to other two-legged tools, such as tin snips or similar.

Die Seitenansicht der Figur 1 zeigt in abgebrochener Darstellung einen Zangenschenkel, beispielsweise einen Zangenschenkel einer Kombizange. Der Zangenschenkel 1 weist ein Loch 2 auf, das bei zusammengesetzter Zange eine Welle zur Bildung des Zangengelenks aufnimmt. Der aus Kunststoff bestehende Griff 3 ist bis fast an diese Öffnung 2 heran gespritzt. Von dem Zangengelenk ausgehend ist zunächst ein erster Absatz 4 gebildet, der etwa die Form eines Quaders aufweist. Dieser Absatz 4 weist eine ebene Endfläche 5 auf, siehe Figur 3. Diese Endfläche 5 umgibt den metallischen Zangenschenkel 1.The side view of Figure 1 shows a broken view a pliers leg, for example a pliers leg a pair of pliers. The pliers leg 1 has a hole 2 on which, when the pliers are assembled, form a wave of the pincer joint. The plastic one Handle 3 is sprayed almost up to this opening 2. Of starting from the pliers joint is a first paragraph 4 formed, which has approximately the shape of a cuboid. This Paragraph 4 has a flat end surface 5, see FIG. 3. This end face 5 surrounds the metallic pliers leg 1.

An den ersten Absatz 4 schließt sich eine ebene Schrägfläche 6 an, die unter einem Winkel von etwa 15° gegenüber der Zangenlängsachse bei geschlossener Zange verläuft. Die Schrägfläche 6 bildet die Begrenzung eines Abgleitschutzes 7. An den Abgleitschutz schließt sich ein Griffbereich 8 an, der konkav ausgebildet ist und dazu bestimmt ist, den Daumen und auf der gegenüberliegenden Seite den Zeigefinger des Benutzers aufzunehmen. In dem sich daran anschließenden Teil verläuft die Außenseite 9 des Griffs in einer geschwungenen Kurve. Der Griff endet dann in einem abgerundeten freien Ende 10.The first paragraph 4 is followed by a flat inclined surface 6 at an angle of about 15 ° to the longitudinal axis of the pliers with the pliers closed. The sloping surface 6 forms the limitation of a slip protection 7 the slip protection is followed by a grip area 8 which is concave and intended to be the thumb and on the opposite side the index finger of the User record. In the part that follows the outside 9 of the handle runs in a curved Curve. The handle then ends in a rounded free end 10th

Die Innenseite 11 des Griffs ist diejenige Seite, die bei montierter Zange dem jeweiligen Handeingriff zugewandt ist. In Figur 1 und 2 ist dies die linke Seite.The inside 11 of the handle is the side that at mounted pliers is facing the respective manual intervention. In Figures 1 and 2, this is the left side.

In Figur 1 ist der Zangengriff dargestellt, wie er nach dem Spritzgießvorgang aussieht. An dem Übergang zwischen der Innenseite 11 und der in den Figuren 1 und 2 obenliegenden Flachseite des Griffs ist eine Kante 12 gebildet, die eine Stufe darstellt. Diese Stufe ist am besten ganz unten in Figur 1 zu sehen. Die Stufe 12 ist auch an der dem Zangengelenk abgewandten Seite des Abgleitschutzes 7 ausgebildet. Auf den in Figur 1 zu sehenden Flachseitenflächen des Griffschenkels 3 ist ein Teil als erhabene Markierung 14 ausgebildet. An den Rändern dieser Markierung 14 sind dadurch ebenfalls Stufen gebildet, die die gleiche Höhe haben wie die Kanten 12. Bei dieser Markierung 14 kann es sich um eine Kennzeichnung der Zange handeln, ggf. auch um eine Kennzeichnung des Herstellers der Zange. In Figure 1, the pliers handle is shown as after Injection molding looks like. At the transition between the Inner side 11 and the one above in FIGS. 1 and 2 An edge 12 is formed on the flat side of the handle, the one Represents level. This level is best at the very bottom in Figure 1 can be seen. Level 12 is also on the pliers joint opposite side of the slide protection 7 is formed. On the flat side surfaces of the handle leg seen in Figure 1 3, a part is designed as a raised marking 14. At the edges of this mark 14 are also Levels that are the same height as that Edges 12. This marking 14 can be a Activate the marking of the pliers, if necessary also a marking the manufacturer of the pliers.

Anschließend wird der Bereich des Handgriffs 3, der zwischen der Stufe 12 der Innenseite 11 und der Stufe 12 des Abgleitschutzes 7 liegt, in einem zweiten Arbeitsschritt mit einem weicheren Material ausgekleidet, beispielsweise wieder in einem Spritzgießvorgang. Hierzu wird der Griff in eine Form eingelegt, in die das Material eingespritzt wird. Dadurch wird der Bereich zwischen den Stufen 12 aufgefüllt, so dass sich die in Figur 2 dargestellte Form des Griffs ergibt. Der Handgriff 3 ist im Bereich seiner Außenseite, also rechts in Figur 2, und im Bereich seiner beiden Flachseiten mit einer Oberfläche versehen, die weicher ist als die Oberfläche der Innenseite 11.
Das Angießen beim Spritzgießen erfolgt an der Fläche 5 oder an der Fläche 6, also an dem Ende des Griffs, der dem Zangengelenk zugeordnet bzw. zugewandt ist. Dadurch kann die gesamte Oberfläche des Griffs, an der ein Benutzer angreifen kann, von einer Angießstelle frei bleiben.Subsequently, the area of the handle 3, which lies between the step 12 on the inside 11 and the step 12 of the slide protection 7, is lined with a softer material in a second working step, for example again in an injection molding process. To do this, the handle is placed in a mold into which the material is injected. This fills the area between the steps 12, so that the shape of the handle shown in FIG. 2 results. The handle 3 is provided in the area of its outside, that is to the right in FIG. 2, and in the area of its two flat sides with a surface which is softer than the surface of the inside 11.
The injection molding takes place on the surface 5 or on the surface 6, that is to say at the end of the handle which is assigned to or facing the pliers joint. This allows the entire surface of the handle that a user can grip to remain clear of a sprue.

Die Figur 3 zeigt in einem Schnitt längs Linie III-III in Figur 2 praktisch die Stirnansicht des dem Zangengelenk zugeordneten Endes des Griffs. An der äußeren Stirnfläche 5, an der das Angießen erfolgt, ist beim Angießen eine Markierung 13 mit hergestellt worden, die beispielsweise als erhabene Markierung oder aber auch als vertiefte Markierung ausgebildet sein kann. Es handelt sich also nicht um ein Aufdrucken eine Markierung, sondern um eine Markierung in dem Material des Griffs. Diese Markierung ist dauerhaft.FIG. 3 shows a section along line III-III in Figure 2 practically the end view of the pincer joint assigned End of the handle. On the outer end face 5 the pouring is a mark when pouring 13 was produced with, for example, as a sublime Marking or formed as a deepened marking can be. So it is not an imprint a mark, but a mark in the material of the handle. This marking is permanent.

Figur 4 zeigt eine Ansicht des Zangengriffs von der Außenseite, also von rechts in Figur 1. Der Rand des Abgleitschutzes 7 enthält beidseits je eine Lücke 15, durch die das Anspritzen des Oberflächenbereiches des Griffschenkels erfolgt. Das Material, das die weichere Oberfläche bilden soll, wird durch diese Lücke 15 hindurch gespritzt und füllt den Zwischenraum zwischen dem harten Teil des Griffs und der Form aus. Das Material fließt auch um die Markierung 14 herum, so dass diese dann bündig mit der Oberfläche des weicheren Materials verläuft.FIG. 4 shows a view of the pliers handle from the outside, So from the right in Figure 1. The edge of the slip protection 7 contains on both sides a gap 15 through which the injection the surface area of the handle leg. The Material that is supposed to form the softer surface is made by this gap 15 is sprayed through and fills the gap between the hard part of the handle and the shape. The material also flows around the marker 14 so that this then runs flush with the surface of the softer material.

Beim Anspritzen, das in diesem Fall also nicht von der oberen Fläche 5, sondern von der Oberfläche 6 her erfolgt, kann an dieser Stirnfläche 6 des Griffs eine reliefartige Markierung aufgebracht werden, die beispielsweise in Figur 5 dargestellt ist. Auf dieser Stirnfläche 6, die größer ist als die Stirnfläche 5, ist mehr Platz für eine solche Markierung vorhanden.When spraying, in this case not from the top Surface 5, but takes place from the surface 6, can this end face 6 of the handle has a relief-like marking applied, which are shown for example in Figure 5 is. On this end face 6, which is larger than the end face 5, there is more space for such a mark.
