Description

Technisches GebietTechnical area

Die Erfindung betrifft eine Werkzeuggriffhülle für ein Betätigungswerkzeug mit einem Griff, wobei die Werkzeuggriffhülle aus einer Kunststoffhülle besteht, welche aus wenigstens zwei Kunststoffkomponenten mit unterschiedlicher Härte besteht und welche den Griff des Betätigungswerkzeugs umschließt, wobei ein Dämpfungselement zur Dämpfung von Schlägen oder Vibrationen, welche über den Griff übertragen werden vorgesehen ist.The invention relates to a tool handle cover for an operating tool with a handle, wherein the tool handle cover consists of a plastic sheath, which consists of at least two plastic components with different hardness and which surrounds the handle of the actuating tool, wherein a damping element for damping shocks or vibrations, which over the Handle is provided to be transferred.

Stand der TechnikState of the art

Werkzeuggriffhüllen mit zwei oder mehr Kunststoffkomponenten unterschiedlicher Härte für Betätigungswerkzeuge mit Griff sind bekannt und werden vielfältig eingesetzt. Beispielsweise sind Schraubendreher, Zangen, Bolzenschneider und andere Betätigungswerkzeuge mit solchen Werkzeuggriffhüllen markterhältlich. Die weichere, sich oft gummiartige anfühlende Kunststoffkomponente erhöht die Griffigkeit desTool handle covers with two or more plastic components of different hardness for actuation tools with handle are known and used in many ways. For example, screwdrivers, pliers, bolt cutters and other actuation tools with such tool handle covers are commercially available. The softer, often rubbery, feeling plastic component increases the grip of the

Werkzeuggriffs und führt zu einer für einen Benutzer als angenehm empfundenen Haptik des Werkzeugs. Demgegenüber dient die ebenfalls in einigen Bereichen bis an die
äußere Oberfläche der Werkzeuggriffhülle geführte härtere Kunststoffkomponente zur eigentlichen Kraftübertragung auf den Griff des Werkzeugs.Tool handle and leads to a user feels pleasant to the touch of the tool. In contrast, the serves also in some areas to the
outer surface of the tool handle shell guided harder plastic component for the actual power transmission to the handle of the tool.

Werkzeuggriffhüllen sind oft ergonomisch geformt, um eine günstige Haltung der Hand und des Arms bei einer Betätigung des Werkzeugs vorzugeben und ein optimales Anliegen der Werkzeuggriffhülle in der Hand zu gewährleisten. Auf diese Weise werden durch einen sicheren Halt und eine korrekte Betätigung des Werkzeugs Unfälle verhindert. Ferner werden schädliche Belastungen der Haut und des Stütz- und Bewegungsapparats der Hand und des Arms vermieden.Tool grips are often ergonomically shaped to provide a favorable hand and arm position when the tool is actuated and to ensure optimum tool handle wrap in the hand. In this way, a safe stop and a correct operation of the tool accidents are prevented. Furthermore, harmful stresses on the skin and the musculoskeletal system of the hand and arm are avoided.

Die DE 103 48 974 A1 beschreibt ebenfalls einen vibrationsgedämpften Handgriff. Bei diesem Handgriff ist zwischen einem Griffelement und einer Griffhülle Schwingungsdämpfendes Mittel vorgesehen. Der Handgriff ist vorzugsweise für Maschinen vorgesehen, um deren Vibrationen beim Nutzer zu kompensieren. Bei handbetätigten Werkzeugen, wie Schraubendrehern, Zangen oder auch Bolzenschneidern werden hingegen vom Nutzer Kräfte über den Handgriff auf das Werkzeug übertragen. Diese Kräfte, können mit diesem Handgriff jedoch nicht gut übertragen werden, da die harte Griffhülle auf dem weicheren Schwingungsdämpfenden Mittel aufliegt. Hierdurch würde es bei der Kraftübertragung sogar zu Problemen führen.The DE 103 48 974 A1 also describes a vibration damped handle. In this handle, vibration damping means is provided between a handle member and a handle cover. The handle is preferably provided for machines to compensate for the vibrations of the user. In hand-operated tools, such as screwdrivers, pliers or bolt cutters, however, are transferred from the user forces on the handle on the tool. These forces, however, can not be transmitted well with this handle, since the hard handle cover rests on the softer vibration damping means. This would even lead to problems in the power transmission.

Auch die WO 92/01596 offenbart einen Handgriff, der eine dämpfende Wirkung entfaltet. Der Handgriff besteht insbesondere aus einer inneren, elastomeren Schicht und einer äußeren zylindrischen Hülle aus gewebtem Stoff, die über der elastomeren Schicht des Griffs vorgesehen ist. Wie bei der DE 103 48 974 A1 ist der Handgriff nicht geeignet Kräfte von dem Nutzer auf das Betätigungswerkzeug zu übertragen, weil die beiden Schichten der Griffhülle übereinanderliegen.Also the WO 92/01596 discloses a handle that provides a cushioning effect. In particular, the handle is comprised of an inner elastomeric layer and an outer cylindrical sleeve of woven fabric provided over the elastomeric layer of the handle. As with the DE 103 48 974 A1 the handle is not suitable to transfer forces from the user to the operating tool, because the two layers of the handle cover are superimposed.

Die US 2006/0174450 A1 zeigt ein handbetätigtes Werkzeug mit einem Handgriff. Der Handgriff besteht aus zwei zylindrischen Schichten, welche koaxial zusammengesteckt vorgesehen sind. Die äußere weiche Schicht eignet sich nicht, um Kraftübertragung von dem Nutzer auf das Werkzeug zu übertragen.The US 2006/0174450 A1 shows a hand-operated tool with a handle. The handle consists of two cylindrical layers, which are provided coaxially plugged together. The outer soft layer is not suitable for transmitting power transmission from the user to the tool.

Die DE 20 2004 002 614 U1 beschreibt einen Griff für Drehmomentschlüssel, welcher aus einer Griffkomponente mit relativ großer Härte und einer zweiten Griffkomponente mit relativ geringer Härte besteht. Die zweite Griffkomponente mit geringer Härte wird von der härteren Griffkomponente getragen und bildet eine weiche Grifffläche, an welche bei einer Benutzung des Drehmomentschlüssels die Hand des Benutzers anliegt.The DE 20 2004 002 614 U1 describes a handle for torque wrench, which consists of a handle component with relatively high hardness and a second handle component with relatively low hardness. The second handle component with low hardness is supported by the harder handle component and forms a soft gripping surface against which the user's hand rests when using the torque wrench.

Sowohl die WO 2007/079787/A1 als auch die DE 10 2005 055 981 haben dieses Prinzip umgekehrt. Die harte Kunststoffkomponente liegt bei den dort beschriebenen Werkzeughüllen auf der weichen Kunststoffkomponente auf. Die harte Kunststoffkomponente umgibt dort die weichere Kunststoffkomponente. Hierdurch wird die Kraft von der Werkzeughülle auf das Werkzeug nicht immer optimal übertragen, da die harte Kunststoffkomponente auf der weicheren quasi schwimmt. Da die Hand immer mit der harten Kunststoffkomponente bei der Betätigung des Werkzeugs in Kontakt kommt, kann es zudem schnell zu einer Blasenbildung in der Handkontaktfläche bei dem Nutzer kommen.Both the WO 2007/079787 / A1 as well as the DE 10 2005 055 981 have reversed this principle. The hard plastic component is on the soft plastic component described in the tool cases described therein. The hard plastic component surrounds the softer plastic component there. As a result, the force from the tool casing to the tool is not always optimally transferred because the hard plastic component floats on the softer quasi. In addition, since the hand always comes in contact with the hard plastic component upon actuation of the tool, blistering in the hand contact surface of the user may quickly occur.

Die bekannten Betätigungswerkzeuge mit Griff haben den Nachteil, dass Schläge und Vibrationen, die bei der Nutzung des jeweiligen Betätigungswerkzeugs auftreten, unmittelbar auf den Nutzer übertragen, werden. Solche Schläge und Vibrationen treten beispielsweise bei der Benutzung von trennenden Werkzeugen, wie Bolzenschneidern, Seitenschneidern oder Kombizangen auf. Dieses wird von dem Benutzer als unangenehm empfunden und belastet zudem den gesamten Organismus des Benutzers. Insbesondere beim Bewegungsapparat der Hände und Arme können durch diese Belastungen Störungen oder Erkrankungen auftreten.The known operating tools with handle have the disadvantage that shocks and vibrations that occur during use of the respective operating tool, transmitted directly to the user, are. Such impacts and vibrations occur, for example, when using separating tools such as bolt cutters, side cutters or combination pliers. This is perceived by the user as unpleasant and also burdens the entire organism of the user. In particular, in the musculoskeletal system of the hands and arms disorders or diseases can occur due to these loads.

Offenbarung der ErfindungDisclosure of the invention

Aufgabe der Erfindung ist es daher, die Nachteile des Standes der Technik zu vermeiden und eine Vorrichtung zu schaffen, welche eine Übertragung von Schlägen oder Vibrationen von dem Werkzeug auf den Körper eines Benutzers teilweise mindert oder ganz verhindert.The object of the invention is therefore to avoid the disadvantages of the prior art and to provide a device which partially reduces or completely prevents transmission of shock or vibration from the tool to a user's body.

Erfindungsgemäß wird die Aufgabe durch eine Werkzeuggriffhülle gemäß Anspruch 1 gelöst.According to the invention, the object is achieved by a tool grip cover according to claim 1.

Mit dem Dämpfungselement werden Schläge und Vibrationen bei einer Benutzung von Betätigungswerkzeugen, wie sie beispielsweise bei Bolzenschneidern, Seitenscheidern und Kombizangen bei einer Trennung als Trennungsschlag auftreten, gedämpft. Durch die Dämpfung der von dem Griff über die Werkzeuggriffhülle auf eine greifende Hand übertragenen Schläge und Vibrationen werden vorteilhaft Muskeln und Gelenke geschont und einer Ermüdung eines Benutzers vorgebeugt. Die Ergonomie des Betätigungswerkzeugs wird erheblich verbessert. Dies bewirkt ein vermindertes Unfallrisiko und eine Reduzierung von gesundheitsschädlichen Belastungen bei einer Betätigung des Werkzeugs.With the damping element are shocks and vibrations when using actuation tools, such as occur in bolt cutters, side cutters and combi pliers at a separation as a separation shock damped. By damping the transmitted from the handle on the tool handle shell on a cross-hand strokes and vibrations muscles and joints are advantageously spared and prevented fatigue of a user. The ergonomics of the operating tool is significantly improved. This causes a reduced risk of accidents and a reduction of harmful loads when operating the tool.

Als vorteilhafte Ausgestaltung der Erfindung erweist sich, wenn das Dämpfungselement aus der weicheren der beiden Kunststoffkomponenten besteht. Die weiche Kunststoffkomponente eignet sich wegen ihrer Materialeigenschaften besonders zur Absorption von Schlägen und Vibrationen. Vorzugsweise liegt die weiche Kunststoffkomponente an einem Griff bzw. einem Griffhebel des Betätigungswerkzeugs an und befindet sich an der Innenseite der Kunststoffhülse. Auf diese Weise wird eine zuverlässige Dämpfung von Schlägen und Vibrationen erreicht. Das Dämpfungselement aus der weicheren der beiden Kunststoffkomponenten lässt sich ferner mit bekannten Herstellungsverfahren kostengünstig und ohne großen Aufwand herstellen.As an advantageous embodiment of the invention, it turns out that the damping element consists of the softer of the two plastic components. Due to its material properties, the soft plastic component is particularly suitable for absorption of shocks and vibrations. Preferably, the soft plastic component bears against a handle or a handle lever of the actuating tool and is located on the inside of the plastic sleeve. In this way, a reliable damping of shocks and vibrations is achieved. The damping element of the softer of the two plastic components can also be produced inexpensively and with little effort with known manufacturing methods.

In einer vorteilhaften Ausbildung der Erfindung besteht das Dämpfungselement aus wenigstens einer Rille oder einem Steg, welcher längs der Innenseite der Kunststoffhülle angeordnet ist. Durch diese Strukturen an der Innenseite der Kunststoffhülle liegen nur Teile der Oberfläche an dem Griff an, während sich dazwischen Hohlräume befinden. Bei einer Belastung Verformen sich die an dem Griff anliegenden Strukturen in die Hohlräume hinein und dämpfen auf diese Weise effektiv Schläge oder Vibrationen. Vorzugweise sind abwechselnd Längsrillen und Stege auf der Innenseite der Kunststoffhüllen vorgesehen. Die Stege liegen an dem Griff an und verformen sich über die Stegbreite zur Dämpfung von Schlägen. Stege oder Rillen lassen sich einfach und kostengünstig bereits bei der Herstellung der Kunststoffhülle realisieren.In an advantageous embodiment of the invention, the damping element consists of at least one groove or a web, which is arranged along the inside of the plastic sheath. Due to these structures on the inside of the plastic cover, only parts of the surface abut the handle, while cavities are located between them. Upon loading, the structures adjacent the handle deform into the cavities, effectively dampening impact or vibration. Preferably, longitudinal grooves and webs are alternately provided on the inside of the plastic sheaths. The bars are located on the handle and deform over the bridge width for damping shocks. Webs or grooves can be realized easily and inexpensively already in the production of the plastic shell.

Eine bevorzugte Ausgestaltung der erfindungsgemäßen Werkzeuggriffhülle besteht ferner darin, dass das Dämpfungselement mehrere Noppen enthält, welche zwischen der Kunststoffhülle und dem Griff vorgesehen sind. Die Noppen verformen sich bei einer Belastung in dazwischen liegende Hohlräume hinein und dämpfen so wirksam Schläge und Vibrationen. Auch Noppen sind preisgünstig und unkompliziert herstellbar.A preferred embodiment of the tool handle casing according to the invention further consists in that the damping element contains a plurality of nubs, which are provided between the plastic sleeve and the handle. The pimples deform under load into intervening cavities, effectively damping shocks and vibrations. Even knobs are inexpensive and easy to produce.

In einer weitem vorteilhaften Ausbildung der erfindungsgemäßen Werkzeuggriffhülle enthält das Dämpfungselement ein dämpfendes Gel. Solche Gele sind z.B. von Laufschuhen oder Fahrradsatteln bekannt. Das Gel dämpft Schläge und Vibrationen besonders wirkungsvoll.In a further advantageous embodiment of the tool grip casing according to the invention, the damping element contains a damping gel. Such gels are e.g. known by running shoes or bicycle saddles. The gel absorbs shocks and vibrations particularly effectively.

Eine besondere Ausgestaltung der erfindungsgemäßen Werkzeuggriffhülle ergibt sich dadurch, dass das Dämpfungselement ein elastisches Federelement aufweist. Das elastische Federelement besteht beispielsweise aus Kunststoff oder Metall. Mit einem solchen Federelement als Dämpfungselement wird ebenfalls eine effektive Dämpfung von Vibrationen oder Schlägen erzielt, welche z.B. bei einer Benutzung von Bolzenschneidern, Seitenscheidern oder Kombizangen auftreten.A particular embodiment of the tool handle casing according to the invention results from the fact that the damping element has an elastic spring element. The elastic spring element consists for example of plastic or metal. With such a spring element as a damping element, an effective damping of vibrations or impacts is also achieved. occur when using bolt cutters, side cutters or combination pliers.

Eine weitere vorteilhafte Ausgestaltung der Erfindung wird dadurch erzielt, dass das Dämpfungselement im Bereich der Kontaktflächen einer Hand vorgesehen ist. An den Kontaktflächen zwischen Hand und Werkzeuggriffhülle findet die Kraftübertragung zwischen Hand und Werkzeuggriffhülle statt. Über diese Flächen werden Schläge und Vibrationen von der Werkzeuggriffhülle an die Hand weitergeleitet. Dämpfungselemente im Bereich der Kontaktflächen dämpfen somit Schläge und Vibrationen direkt beim Ort der Übertragung auf die Hand.A further advantageous embodiment of the invention is achieved in that the damping element is provided in the region of the contact surfaces of a hand. At the contact surfaces between the hand and tool handle cover, the power transmission between the hand and tool handle cover takes place. Impacts and vibrations are transmitted from the tool grip to the hand via these surfaces. Damping elements in the area of the contact surfaces thus dampen shocks and vibrations directly at the place of transfer to the hand.

Ferner ist die Werkzeuggriffhülle in einer bevorzugten Ausbildung der Erfindung ergonomisch an eine greifende Hand angepasst. Durch die ergonomische Form wird eine günstige Haltung von Hand und Arm bei einer Betätigung des Werkzeugs vorgeben und ein optimales Anliegen der Werkzeuggriffhülle an die greifende Hand erzielt. Durch einen sicheren Halt und eine korrekte Betätigung des Werkzeugs werden Beschädigungen am Werkzeug, einem Werkstoff oder der Umgebung und Verletzungen des Benutzers vermieden. Weiterhin werden schädliche Belastungen der Haut und des Bewegungsapparats der Hand und des Arms vermieden.Furthermore, in a preferred embodiment of the invention, the tool grip sleeve is ergonomically adapted to a grasping hand. Due to the ergonomic shape is a favorable attitude of hand and arm pretend on actuation of the tool and achieved an optimal concern of the tool grip cover to the gripping hand. A secure hold and proper operation of the tool will damage the tool, material or environment and cause injury avoided by the user. Furthermore, harmful strains on the skin and musculoskeletal system of the hand and arm are avoided.

Bevorzugtes AusführungsbeispielPreferred embodiment

In Fig. 1 wird mit 10 eine Werkzeuggriffhülle für ein Betätigungswerkzeug bezeichnet. Die Werkzeuggriffhülle 10 ist beispielsweise bei trennenden Betätigungswerkzeugen, wie Bolzenschneider, Mattenschneider, Gitterrostschneider, Bolzenvornschneider, Seitenschneider, Kraftseitenschneider, Kombizangen, Kraftkombizangen und Kabelscheren einsetzbar. Dazu nimmt die Werkzeuggriffhülle 10 mit einer Öffnung 12 einen in Fig. 1 nicht dargestellten Griff oder Griffhebel des ebenfalls nicht dargestellten Betätigungswerkzeugs auf, umschließt den Griff oder Griffhebel und ist mit diesem fest verbunden.In Fig. 1 10 is a tool grip cover for an actuating tool. The tool handle shell 10 can be used, for example, in separating actuating tools, such as bolt cutters, mat cutters, wire mesh cutters, bolt cutters, side cutters, force side cutters, combination pliers, power packs and cable shears. For this purpose, the tool grip casing 10 with an opening 12 takes a in Fig. 1 not shown handle or handle lever of the actuating tool, also not shown, surrounds the handle or handle lever and is firmly connected thereto.

Die Werkzeuggriffhülle 10 besteht aus einer Kunststoffhülle mit einer harten Kunststoffkomponenten 14 und einer, relativ zur harten Kunststoffkomponenten 14, weichen Kunststoffkomponente 16. In alternativen Ausführungen sind mehr als zwei Kunststoffkomponenten mit unterschiedlichen Materialeigenschaften in der Werkzeuggriffhülle 10 enthalten. Die harte Kunststoffkomponente 14 dient unter anderem zur zuverlässigen Kraftübertragung von einer Hand auf den Griff und besteht aus einem geeigneten Hartkunststoff. Die weiche Kunststoffkomponente 16 kann z.B. aus einem sich gummiartig anfühlenden Weichkunststoff bestehen. Durch die weiche Kunststoffkomponente 16 wird die Griffigkeit erhöht. Die Werkzeuggriffhülle 10 ist abrutschsicherer. Weiterhin erzeugt die weiche Kunststoffkomponente 16 eine angenehme haptische Wahrnehmung für einen Benutzer bei einer Betätigung des Werkzeugs.The tool grip shell 10 consists of a plastic shell with a hard plastic component 14 and a soft plastic component 16 relative to the hard plastic components 14. In alternative embodiments, more than two plastic components with different material properties are contained in the tool grip shell 10. The hard plastic component 14 is used inter alia for reliable power transmission from one hand to the handle and consists of a suitable hard plastic. The soft plastic component 16 may e.g. consist of a rubber-like soft plastic. The soft plastic component 16 increases the grip. The tool grip shell 10 is slip-proof. Furthermore, the soft plastic component 16 creates a pleasant haptic perception for a user upon actuation of the tool.

Weiterhin ist die Werkzeuggriffhülle 10 ergonomisch geformt und verfügt über entsprechende Formelemente 18. Hierdurch wird eine optimale Position und Haltung von Hand und Arm des Benutzers vorgeben und ein gutes Anliegen der Werkzeuggriffhülle an die Hand erzielt. Durch einen sicheren Halt und eine korrekte Betätigung des Werkzeugs werden Unfälle vermieden und schädigende Belastungen der Haut und des Bewegungsapparats reduziert.Furthermore, the tool handle shell 10 is ergonomically shaped and has corresponding form elements 18. This will give an optimal position and attitude of the hand and arm of the user and achieved a good concern of the tool grip shell to the hand. A secure hold and proper operation of the tool prevents accidents and reduces damaging stress on the skin and musculoskeletal system.

Um die Öffnung 12 ist eine Abdeckung 20 vorgesehen, um ein dahinter befindliches Dämpfungselement (s. Fig. 2 bis 5) vor Verschmutzung zu schützen. Die Abdeckung 20 ist durch Einpressen oder Klebung bündig mit der Werkzeuggriffhülle 10 verbunden. An dem der Öffnung 12 gegenüberliegendem Ende ist die Werkzeuggriffhülle 10 durch einen Abschuss 22 geschlossen ausgebildet. Der Abschluss 22 ist entweder integraler Bestandteil der Werkzeuggriffhülle 10 oder als aufgesteckte, geschraubte, geklebte oder eingepresste Kappe mit der Werkzeuggriffhülle 10 verbunden. Auf diese Weise wird das Ende des Griffs oder Griffhebels vor Beschädigung oder Verschmutzung geschützt.To the opening 12, a cover 20 is provided to a behind it located damping element (s. Fig. 2 to 5 ) to protect against contamination. The cover 20 is connected by pressing or gluing flush with the tool handle shell 10. At the end opposite the opening 12, the tool grip cover 10 is formed closed by a launch 22. The end 22 is either an integral part of the tool handle shell 10 or connected as plugged, screwed, glued or pressed cap with the tool handle shell 10. In this way, the end of the handle or handle lever is protected from damage or contamination.

In Fig. 2 wird die Werkzeuggriffhülle 10 nach Fig. 1 in einem Schnitt entlang der Linie AB in Fig. 1 dargestellt. Gleiche Bestandteile werden daher mit entsprechenden Bezugszeichen bezeichnet. Deutlich sind in Fig. 2 Rillen 30 und Stege 32 an der Innenfläche 34 der Werkzeuggriffhülle 10 zu erkennen. Die Stege 32 liegen an dem Griff oder Griffhebel des Betätigungswerkzeugs an und befinden sich gegenüber einer Kontaktfläche einer Hand, an der die weiche Kunststoffkomponente 16 außen an der Werkzeuggriffhülle 10 angeordnet ist.In Fig. 2 the tool grip 10 is after Fig. 1 in a section along the line AB in Fig. 1 shown. The same components are therefore designated by corresponding reference numerals. Are clearly in Fig. 2 Grooves 30 and webs 32 on the inner surface 34 of the tool handle shell 10 can be seen. The webs 32 abut against the handle or handle lever of the actuating tool and are located opposite a contact surface of a hand, on which the soft plastic component 16 is arranged on the outside of the tool grip casing 10.

In dieser Ausführung werden die Stege 32 durch die harte Kunststoffkomponente 14 gebildet und stellen zusammen mit den Rillen 30 ein Dämpfungselement 36 dar. Bei einer Belastung verformen sich die Stege 32 in die Rillen 30 hinein und absorbieren auf diese Weise Schläge und Vibrationen, wie beispielsweise Trennschläge beim Trennen von Bolzen oder Kabeln. Je nach Breite und Form der Stege 32 wird eine unterschiedlich starke Dämpfung vorgegeben. Breite Stege 32 dämpfen beispielsweise geringer als schmale.In this embodiment, the webs 32 are formed by the hard plastic component 14 and together with the grooves 30 constitute a damping element 36. Under load, the webs 32 deform into the grooves 30 and thus absorb shocks and vibrations, such as separation impacts when disconnecting bolts or cables. Depending on the width and shape of the webs 32 a different degrees of damping is given. For example, wide webs 32 attenuate less than narrow ones.

In alternativen Ausführungen werden die Stege 32 von der weichen Kunststoffkomponente 16 gebildet oder bestehen aus einem weichen angespritzten Kunststoff. Die Verformbarkeit der weichen Kunststoffkomponente 16 oder des zusätzlich verwendeten weichen Kunststoffs erhöhen die Absorption von Schlägen und Vibrationen durch die Stege 32. Somit trägt nicht nur eine Struktur sondern auch das Material der Stege 32 wesentlich zur Dämpfung bei.In alternative embodiments, the webs 32 are formed by the soft plastic component 16 or consist of a soft molded plastic. The deformability of the soft plastic component 16 or the additionally used soft plastic increase the absorption of shocks and vibrations by the webs 32. Thus, not only a structure but also the material of the webs 32 contributes substantially to the damping.

Fig. 3 zeigt ein weiteres Ausführungsbeispiel einer Werkzeuggriffhülle 10 mit einem Dämpfungselement 36 in einer Schnittansicht. Der Ausführung nach Fig. 1 und Fig. 2 entsprechende Bestandteile werden in Fig. 3 mit gleichen Bezugszeichen bezeichnet. Fig. 3 shows a further embodiment of a tool grip shell 10 with a damping element 36 in a sectional view. The execution after Fig. 1 and Fig. 2 appropriate ingredients are in Fig. 3 denoted by the same reference numerals.

Entsprechendes gilt auch für die Fig. 4 und die Fig. 5. Das Dämpfungselement 36 wird durch Noppen 38 realisiert. Die Noppen befinden sich in einer Ausnehmung 40 in der Innenfläche 34 der Werkzeuggriffhülle 10 gegenüber der Kontaktfläche einer Hand, an welcher die weiche Kunststoffkomponente 16 außen an der Werkzeuggriffhülle 10 angeordnet ist. Die Stirnseiten der Noppen 38 liegen an dem in Fig. 3 nicht dargestellten Griff oder Griffhebel des Betätigungswerkzeugs an.The same applies to the Fig. 4 and the Fig. 5 , The damping element 36 is realized by nubs 38. The nubs are located in a recess 40 in the inner surface 34 of the tool handle shell 10 opposite the contact surface of a hand, on which the soft plastic component 16 is arranged on the outside of the tool handle shell 10. The faces of the nubs 38 are located on the in Fig. 3 not shown handle or handle lever of the actuating tool on.

Durch eine Verformung der Noppen 38 bei einer Belastung in die Ausnehmung 40 hinein erfolgt eine Dämpfung von Schlägen und Vibrationen, z.B. einem Trennschlag bei trennenden Betätigungswerkzeugen. Die Noppen 38 werden entweder durch die harte Kunststoffkomponente 14, die weiche Kunststoffkomponente 16 oder einer zusätzlichen, vorzugsweise weichen Kunststoffkomponente ausgebildet.Deformation of the nubs 38 upon loading into the recess 40 damps shocks and vibrations, e.g. a separation stroke with separating actuating tools. The nubs 38 are formed either by the hard plastic component 14, the soft plastic component 16 or an additional, preferably soft plastic component.

In Fig. 4 wird ein Ausschnitt einer Werkzeuggriffhülle 10 mit einem sehr weichen Kunststoff 42, wie beispielsweise einem Gel, als Dämpfungselement 36 dargestellt. Der sehr weiche Kunststoff 42 ist in einer Ausnehmung 44 auf der Innenfläche 34 der Werkzeuggriffhülle 10 angeordnet und liegt formschlüssig an dem Griff oder dem Griffhebel des Betätigungswerkzeugs an. Dabei füllt der sehr weiche Kunststoff 42 die Ausnehmung 44 ebenfalls formschlüssig aus und befindet sich gegenüber der Handkontaktfläche mit der weichen Kunststoffkomponente 16 an der Außenseite der Werkzeuggriffhülle 10.In Fig. 4 For example, a section of a tool grip cover 10 with a very soft plastic 42, such as a gel, as a damping element 36 is shown. The very soft plastic 42 is disposed in a recess 44 on the inner surface 34 of the tool handle shell 10 and is positively against the handle or the handle lever of the actuating tool. In this case, the very soft plastic 42 also fills the recess 44 in a form-fitting manner and is located opposite the hand-contact surface with the soft plastic component 16 on the outside of the tool grip cover 10.

Durch die hohe Verformbarkeit des sehr weichen Kunststoffs 42 wird eine effektive Dämpfung von Schlägen oder Vibrationen im Bereich der Handkontaktfläche erzielt. Die Dämpfung erfolgt zum überwiegenden Teil durch die Materialeigenschaften des sehr weichen Kunststoffs 42. Es ist aber auch eine Ausformung von Strukturen, wie z.B. Hohlräume zwischen dem sehr weichen Kunststoff 42 und der Ausnehmung 44 oder des Griffs des Werkzeugs für ein optimales Dämpfungsverhalten möglich. In einer weiteren Ausführung wird das Dämpfungselement 36 durch die weiche Kunststoffkomponente 16 gebildet, wobei sich die weiche Kunststoffkomponente 16 im Bereich der Handkontaktfläche von der Innenfläche 34 bis an die äußere Oberfläche der Werkzeuggriffhülle 10 erstreckt. Auch auf diese Weise wird eine Dämpfung von Schlägen und Vibrationen erzielt.Due to the high deformability of the very soft plastic 42 effective damping of shock or vibration in the area of the hand contact surface is achieved. The damping takes place for the most part by the material properties of the very soft plastic 42. However, it is also a formation of structures, such as cavities between the very soft plastic 42 and the recess 44 or the handle of the tool for optimal damping behavior possible. In a further embodiment, the damping element 36 is formed by the soft plastic component 16, wherein the soft plastic component 16 extends in the region of the hand contact surface of the inner surface 34 to the outer surface of the tool grip shell 10. Also in this way a damping of shocks and vibrations is achieved.

Fig. 5 zeigt einen Schnitt durch eine Werkzeuggriffhülle mit einem Dämpfungselement 36, welches Federelemente 46 enthält. Die Federelemente 46 bestehen aus Kunststoff oder Metall oder sind als integraler Bestandteil der harten Kunststoffkomponente 14 oder der weichen Kunststoffkomponente 16 ausgebildet. Die Federelemente 46 sind in einer Ausnehmung 48 der Werkzeuggriffhülle 10 zwischen einem Griff oder Griffhebel des Werkzeugs und der Werkzeuggriffhülle 10 angeordnet. Ein Teil eines Federelements 46 liegt dabei an dem Griff an, während ein anderer Teil von der Werkzeuggriffhülle im Bereich einer Handkontaktfläche getragen wird. Durch diese Maßnahme dämpfen die Federelemente 46 Trennschläge und andere unerwünschte Vibrationen und Schläge bei einer Betätigung des Werkzeugs. Die Federelemente 46 sind in dieser Ausführung als Blattfedern ausgestaltet. Es ist aber auch eine Verwendung von Membran-, Teller-, Spiral- oder Schraubenfedern als Federelement 46 möglich. Fig. 5 shows a section through a tool grip shell with a damping element 36, which includes spring elements 46. The spring elements 46 are made of plastic or metal or are formed as an integral part of the hard plastic component 14 or the soft plastic component 16. The spring elements 46 are arranged in a recess 48 of the tool grip casing 10 between a handle or handle lever of the tool and the tool grip casing 10. A part of a spring element 46 rests against the handle, while another part is carried by the tool handle cover in the region of a hand contact surface. By this measure, the spring elements 46 dampen separation and other unwanted vibrations and shocks upon actuation of the tool. The spring elements 46 are configured in this embodiment as leaf springs. But it is also a use of membrane, plate, coil or coil springs as spring element 46 possible.

Durch das Dämpfungselement 36 der Werkzeuggriffhülle 10 werden Schläge und Vibration bei einer Betätigung des Werkzeugs effektiv gedämpft. Die Ergonomie der Werkzeuggriffhülle 10 und somit des gesamten Betätigungswerkzeugs wird verbessert. Dadurch werden eine Ermüdung des Benutzers und ein Unfallrisiko bei einer Benutzung verringert. Weiterhin werden gesundheitsschädliche Belastung reduziert und somit Muskeln und Gelenke geschont.By the damping element 36 of the tool handle shell 10 shocks and vibration are effectively attenuated upon actuation of the tool. The ergonomics of the tool grip 10 and thus the entire operating tool is improved. This reduces fatigue of the user and a risk of accident during use. Furthermore, health-damaging stress is reduced and thus muscles and joints are spared.
