In order to protect the fuse element against damage during operation of the power tool and to be able to integrate the fuse element obscured in the handle, the elastic element advantageously surrounds the securing element.
Ferner wird vorgeschlagen, dass das Sicherungselement im elastischen Element mittig entlang einer Mittelachse angeordnet ist, wodurch bei einer Kippbewegung unerwünschte Zugspannungen im Sicherungselement und eine damit verbundene Schwingungsübertragung vermieden werden können.It is also proposed that the securing element is arranged centrally in the elastic element along a central axis, whereby undesired tensile stresses in the securing element and an associated vibration transmission can be avoided during a tilting movement.
Ist das Sicherungselement im montierten Zustand auf Zug und das elastische Element auf Druck belastet, kann eine höhere Belastbarkeit des elastischen Elements erreicht werden als ohne Vorspannung, und ein Brechen, ein Ablösen vom Griffteil und vom Befestigungsteil und/oder ein Reißen des elastischen Elements kann vermieden werden. Ferner kann das Sicherungselement vorteilhaft dazu genutzt werden, das elastische Element am Griffteil und am Befestigungsteil zu befestigen, beispielsweise indem durch das Sicherungselement für eine Klebeverbindung eine erforderliche Anpresskraft aufgebracht wird. Die Druckspannung kann vorteilhaft im elastischen Element durch Spannen des Sicherungselements erreicht werden, beispielsweise durch Spannen eines vorteilhaft im elastischen Element mittig entlang einer Mittelachse angeordneten biegeweichen Sicherungselements mit einer Spannschraube.If the securing element in the mounted state to train and the elastic member loaded on pressure, a higher load capacity of the elastic member can be achieved as without bias, and breaking, detachment from the handle part and the fastening part and / or a rupture of the elastic member can be avoided become.

The compressive stress can advantageously be achieved in the elastic element by tensioning the securing element, for example by tensioning a bending-elastic securing element, which is advantageously arranged centrally in the elastic element along a central axis, with a clamping screw.
In einer weiteren erfindungsgemäßen Ausgestaltung wird vorgeschlagen, dass das Sicherungselement von einem Band gebildet ist, das das elastische Element umschließt. Das bandförmige Sicherungselement kann durch seine geschlossene Oberfläche das elastische Element, das aus einem in der Regel weichen Werkstoff gebildet ist, vor äußeren Einflüssen und Beschädigungen während eines Betriebs schützen, beispielsweise vor Hitze, UV-Einwirkungen, Staub, Feuchtigkeit und harten Gegenständen usw. Das Band kann aus verschiedenen, dem Fachmann als sinnvoll erscheinenden Materialien hergestellt sein, beispielsweise aus einem Gewebeband usw. Grundsätzlich kann das Sicherungselement kostengünstig auch aus zumindest einem biegeweichen Bauteil gebildet sein, das radial außerhalb des elastischen Elements angeordnet ist, beispielsweise aus einem oder mehreren Seilen.In a further embodiment of the invention it is proposed that the securing element is formed by a band which surrounds the elastic element. The band-shaped By its closed surface, the securing element can protect the elastic element, which is formed of a generally soft material, from external influences and damage during operation, for example from heat, UV effects, dust, moisture and hard objects, etc. The band can Basically, the securing element can be inexpensively formed from at least one flexurally soft component, which is arranged radially outside of the elastic element, for example, from one or more cables.

In einer nicht erfindungsgemäßen Ausführungsform kann das Sicherungelement anstatt von einem biegeweichen Bauteil auch von einem starren Bauteil gebildet sein, das relativ zum Befestigungsteil und/oder zum Griffteil beweglich gelagert ist. Das Sicherungselement kann einfach montierbar und auch demontierbar ausgeführt werden, so dass es nach einem Schadensfall ausgewechselt werden kann. Ferner kann insbesondere über ein starres Sicherungselement einfach durch das Sicherungselement eine maximale Auslenkung des elastischen Elements aus einer Grundstellung zumindest in eine Kipprichtung und/oder eine Schubrichtung bestimmt werden. Eine Überdehnung des elastischen Elements kann durch das Sicherungselement vermieden und eine lange Lebensdauer kann erreicht werden.In one embodiment not according to the invention, instead of a flexible component, the securing element may also be formed by a rigid component which is movably mounted relative to the fastening part and / or to the grip part. The fuse element can be easily assembled and also made removable, so that it can be replaced after a damage.

Das Sicherungselement ist in dieser Ausführungsform vorteilhaft im Befestigungsteil fest und zum Griffteil beweglich gelagert, wodurch ein Bauraum im Griffteil vorteilhaft für eine Bewegungsfreiheit des Sicherungselements genutzt und eine einfache Montage vom Griffteil aus erreicht werden kann. Ferner kann eine im Befestigungsteil angeordnete Befestigungsschraube für eine feste Verbindung des Sicherungselements genutzt werden. Zusätzliche Befestigungsteile für das Sicherungselement können eingespart werden. Grundsätzlich könnte das Sicherungselement jedoch auch fest im Griffteil und beweglich zum Befestigungsteil ausgeführt sein.The securing element is advantageous in this embodiment fixed in the fastening part and movably mounted to the handle part, whereby a space in the handle part advantageously used for freedom of movement of the fuse element and a simple assembly of the handle can be achieved. Furthermore, a fixing screw arranged in the fastening part can be used for a firm connection of the securing element. Additional fasteners for the fuse element can be saved. In principle, however, the securing element could also be designed to be fixed in the grip part and movable to the fastening part.
In einer nicht erfindungsgemäßen Ausführungsform wird ferner vorgeschlagen, dass das Sicherungselement von einer Schraube gebildet ist, die insbesondere vorteilhaft in der Befestigungsschraube im Befestigungsteil verschraubt werden kann. Eine Schraube ist besonders kostengünstig und kann besonders einfach und schnell montiert und demontiert werden. Anstatt einer Schraube könnte jedoch auch ein Bolzen verwendet werden, der entweder im Griffteil oder im Befestigungsteil form-, kraft- und/oder stoffschlüssig befestigt sein kann, beispielsweise kann dieser in der Befestigungsschraube im Befestigungsteil eingepresst sein.In a non-inventive embodiment, it is further proposed that the securing element is formed by a screw, which can be screwed particularly advantageous in the fastening screw in the fastening part.

Um nach einem Spritzvorgang des elastischen Elements eine vorteilhafte gleichmäßige Abkühlung, ein vorteilhaft homogenes Gefüge und eine vorteilhaft stoffschlüssige Anbindung an das Befestigungsteil und/oder an das Griffteil zu ermöglichen, besitzt das elastische Element zumindest kurz vor einer vorteilhaft runden Anlagefläche zum Befestigungselement und/oder zum Griffteil eine unrunde Querschnittsfläche, die kleiner ist als die Anlagefläche, und zwar setzt sich die Querschnittsfläche aus einer runden Kernfläche und sich radial an die Kernfläche nach außen anschließenden bogenförmigen Erstreckungen zusammen. Mit einer runden Kontur kann eine vorteilhaft große Anlagefläche zwischen dem elastischen Element, dem Befestigungselement und dem Griffteil erreicht werden. Durch die sich daran anschließende kleinere Querschnittsfläche kann der Anlagebereich vorteilhaft abgekühlt werden.In order to allow an advantageous uniform cooling, an advantageous homogeneous structure and an advantageous cohesive connection to the fastening part and / or to the handle part after an injection process of the elastic element, the elastic element has at least just before an advantageous circular bearing surface for fastening element and / or Handle part a non-circular cross-sectional area which is smaller than the contact surface, namely, the cross-sectional area of a round core surface and radially to the core surface outwardly adjoining arcuate extensions together.

By the adjoining smaller cross-sectional area of the contact area can be advantageously cooled.
Ferner kann zu einem vorteilhaften Gefüge beigetragen werden, indem bei der Herstellung des elastischen Elements über zumindest ein Bauteil Wärme aus einem inneren Bereich des elastischen Elements abgeführt wird. Das Bauteil kann durch ein bereits bei der Herstellung in das elastische Element eingelegtes Sicherungselement oder vorteilhaft von einem Kern gebildet sein, der nach der Herstellung vom elastischen Element entfernt wird und vorteilhaft eine Ausnehmung für das Sicherungselement bildet. Der Kern kann gegenüber dem eingelegten Sicherungselement vorteilhaft durch einen Kühlkanal mit einem Kühlmittel gekühlt sein. Insbesondere bei Sicherungselementen, die von starren Bauteilen gebildet sind und nach der Herstellung des elastischen Elements einfach montiert werden können, bietet sich eine Kühlung des elastischen Elements bei der Herstellung durch einen Kern vorteilhaft an.Furthermore, an advantageous microstructure can be contributed by heat being removed from an inner region of the elastic element via at least one component during the production of the elastic element. The component can be formed by an already inserted in the production in the elastic element fuse element or advantageously of a core, which is removed after the production of the elastic element and advantageously forms a recess for the securing element. The core can advantageously be cooled relative to the inserted securing element by a cooling channel with a coolant. Especially with security elements, which are formed by rigid components and can be easily mounted after the production of the elastic element, a cooling of the elastic element in the production by a core is advantageous.

Erfindungsgemäß ist das Griffteil 12 neben dem elastischen Kunststoffelement 14 über ein bewegliches Sicherungselement 20 mit dem Befestigungsteil 16 verbunden (
Am Befestigungsteil 16 und am Griffteil 12 ist jeweils eine Hülse 34, 36 befestigt, die jeweils in Richtung zum elastischen Kunststoffelement 24 eine Scheibe 38, 40 mit koaxialen Öffnungen 42, 44 aufweist. Die Hülsen 34, 36 und die Scheiben 38, 40 begrenzen jeweils einen mit elastischem Material ausgespritzten Raum 46, 48, in die das Sicherungselement 22 mit seinen Scheiben 30, 32 eingefügt ist. Die Scheiben 30, 32 des Sicherungselements 22 besitzen einen größeren Durchmesser als die Öffnungen 42, 44 und sind verliersicher in den Räumen 46, 48 gehalten.On the
Zur Montage kann die Scheibe 30 vom stabförmigen Teil des Sicherungselements 22 abgeschraubt werden. Anschließend kann das Sicherungselement 22 vor der Montage der Hülsen 34, 36 mit dem Griffteil 12 bzw. dem Befestigungsteil 16 in diese eingeführt und die Scheibe 30 wieder mit dem stabförmigen Teil verschraubt werden. Die Hülsen 34, 36 sind über nicht näher dargestellte Gewindeverbindungen mit dem Griffteil 12 bzw. dem Befestigungsteil 16 verbunden. Nachdem die Hülsen 34, 36 mit dem Griffteil 12 und dem Befestigungsteil 16 verbunden sind, wird das Sicherungselement 22 mit elastischem Kunststoff umspritzt.For mounting, the
Die Hülsen 34, 36 stellen mit ihren Scheiben 38, 40 vorteilhaft eine formschlüssige Verbindung zwischen dem Griffteil 12 und dem elastischen Kunststoffelement 24 und zwischen dem elastischen Kunststoffelement 24 und dem Befestigungsteil 16 her. Grundsätzlich könnte jedoch das elastische Kunststoffelement mit dem Sicherungselement, den Hülsen und den Scheiben als vormontierbare Baugruppe ausgeführt sein, die anschließend mit dem Griffteil und dem Befestigungsteil verschraubt und verklebt wird.The
Durch eine Bewegungsfreiheit der Scheiben 30, 32 des Sicherungselements 22 in den Räumen 46, 48 ist eine maximale Auslenkung des elastischen Kunststoffelements 24 bestimmt, und zwar in sämtliche Richtungen. Um eine Schwingungsübertragung über das Sicherungselement 22 zu vermeiden, besitzt das Sicherungselement 22 zu den Hülsen 34, 36 und den Scheiben 38, 40 bei einem bestimmungsgemäßen Betrieb einen mit elastischem Material ausgefüllten Abstand.By a freedom of movement of the
In
An einem Befestigungsteil 70 und an einem Griffteil 72 ist jeweils ein Formteil 74, 76 angeformt, das jeweils in Richtung zum elastischen Kunststoffelement 24 scheibenförmig ausgeführt ist und koaxiale Öffnungen 78, 80 aufweist.On a
Die Formteile 74, 76 begrenzen jeweils einen mit elastischem Material ausgespritzten Raum 82, 84, in die das einstückig ausgeführte Sicherungselement 64 mit seinen scheibenförmigen Enden 66, 68 bei der Montage eingefügt ist. Dabei wird das Sicherungselement 64 mit seinem stabförmigen Teil quer zur Längsrichtung des Handgriffs 62 durch seitliche Öffnungen 86, 88 der Formteile 74, 76 geführt (
Vorteilhaft ist eine Breite 100 der Öffnungen 86, 88 quer zur Längsrichtung des Handgriffs 62 und senkrecht zur Einführrichtung 90 des Sicherungselements 64 kleiner ausgeführt als ein Durchmesser 102 des stabförmigen Teils des Sicherungselements 64, so dass das Sicherungselement 64 gegen einen Widerstand durch die Öffnungen 86, 88 geschoben werden muss und anschließend in den Öffnungen 78, 80 der Formteile 74, 76 einrastet. Das Sicherungselement 64 ist in den Öffnungen 78, 80 der Formteile 74, 76 gesichert, und die Formteile 92, 94 können vorteilhaft eingespart werden.Advantageously, a
Um vorteilhaft eine Schwingungsübertragung über das Sicherungselement 28 zu vermeiden, ist dieses länger als das elastische Kunststoffelement 52 ausgeführt. Das elastische Kunststoffelement 52 ist durch das Sicherungselement 28 vor äußeren Einflüssen und Beschädigungen während eines Gebrauchs des Winkelschleifers geschützt. Ferner ist durch das Sicherungselement 28 eine maximale Auslenkung des elastischen kunststoffelements 52 aus einer Grundstellung bestimmt, und zwar in Schub-, Kipp- und Zugrichtung. In den maximalen Auslenkstellungen ist das Sicherungselement 28 gespannt und vermeidet eine weitere Auslenkung des elastischen Kunststoffelements 52.To advantageously avoid vibration transmission via the securing
In den
Bei der Herstellung des Handgriffs 104 werden zuerst das Befestigungsteil 110 und das Griffteil 106 aus Kunststoff gespritzt, wobei in das Befestigungsteil 110 eine Befestigungsschraube 114 eingelegt und in axialer Richtung und in Drehrichtung formschlüssig umspritzt wird, die neben einem Außengewinde 118 zur Befestigung an einem Maschinengehäuse in Richtung Griffteil 106 ein Innengewinde 120 aufweist. Die Befestigungsschraube 114 könnte auch nachträglich in ein Befestigungsteil eingepresst sein. Nach dem Umspritzen der Befestigungsschraube 114 werden das Befestigungsteil 110 mit der Befestigungsschraube 114 und das Griffteil 106 in eine Gussform 140 eingelegt, um in einem Spritzvorgang mit dem elastischen Kunststoffelement 108 stoffschlüssig verbunden zu werden (
Ferner ist in die Gussform 140 ein über einen Flüssigkeitskanal 148 gekühlter Kern 142 eingebracht, der eine Ausnehmung 144 für das Sicherungselement 112 bildet, über den vom inneren Bereich des elastischen Kunststoffelements 108 bei der Herstellung Wärme abgeführt wird. Das Griffteil 106 ist innen hohl ausgeführt und besitzt in Richtung Befestigungsteil 110 eine Ausnehmung 138, durch die der Kern 142 ragt und die teilweise mit dem elastischen Kunststoffelement 108 ausgespritzt wird, so dass ein Randbereich der Ausnehmung 138 von einem Bund 150 des elastischen Kunststoffelements 108 hintergriffen wird.Further, a
Ist das elastische Kunststoffelement 108 ausgekühlt und ist der Kern 142 entnommen, wird das Sicherungselement 112 vom Griffteil 106 durch die vom Kern 142 hergestellte Ausnehmung 144 in Richtung Befestigungsteil 110 durch das elastische Kunst-stoffelement 108 geführt und in das Innengewinde 120 in der Befestigungsschraube 114 geschraubt. Das Sicherungselement 112 besitzt einen Schraubenkopf 132, der im montierten Zustand des Sicherungselements 112 einen Abstand zum Griffteil 106 aufweist, so dass das Sicherungselement 112 relativ zum Griffteil 106 beweglich gelagert ist. Der Schraubenkopf 132 ist größer als die Ausnehmungen 138 und 144, so dass bei einem Schadensfall des elastischen Kunststoffelements 108 das Griffteil 106 verliersicher mit dem Befestigungsteil 110 verbunden ist. Der Abstand zwischen dem Schraubenkopf 132 und dem Griffteil 106 bestimmt eine maximal zulässige Auslenkung des elastischen Kunststoffelements 108. Durch den Bund 150 wird bei einer maximalen Auslenkung ein direkter Kontakt zwischen dem Schraubenkopf 132 und dem Griffteil 106 verhindert und eine Schwingungsübertragung weitgehend vermieden.If the elastic
