Description

Die Erfindung betrifft einen Handgriff für ein Arbeitsgerät mit einem Antriebsmotor und ein im Handgriff angeordnetes Betätigungsglied zur Steuerung der Drehzahl des Antriebsmotors nach dem Oberbegriff des Anspruchs 1.The invention relates to a handle for a working device with a drive motor and an actuating handle arranged in the handle for controlling the rotational speed of the drive motor according to the preamble of claim 1.

Arbeitsgeräte mit einem Antriebsmotor wie Motorkettensägen, Freischneider, Blasgeräte oder dergleichen tragbare Arbeitsgeräte sind aus den Druckschriften WO 2013/122267 A1 und WO 2012/126173 A1 bekannt. Zur Steuerung der Drehzahl des Antriebsmotors ist im Handgriff ein Betätigungsglied angeordnet, welches eine Druckfläche zur Auflage der Finger einer Benutzerhand aufweist. In einer Ausgangslage bei stillstehendem Antriebsmotor liegt das Betätigungsglied mit seiner Druckfläche oberhalb der Grifffläche des Handgriffs; das Betätigungsglied steht aus der Grifffläche des Handgriffs vor. Greift der Benutzer den Handgriff, liegen mehrere Finger auf der Druckfläche des Betätigungsgliedes auf und verstellen dieses in eine Betriebsstellung für einen Dauerbetrieb des drehenden Antriebsmotors. Diese Betriebstellung für einen Dauerbetrieb ist meist eine regelmäßige, maximale Betriebsstellung. In dieser Betriebsstellung ist das Betätigungsglied in den Handgriff eingetaucht, derart, dass die Druckfläche des Betätigungsgliedes auf einer Höhe mit der Grifffläche des Handgriffs liegt.Work tools with a drive motor such as motor chain saws, brush cutters, blowers or the like portable implements are from the publications WO 2013/122267 A1 and WO 2012/126173 A1 known. For controlling the rotational speed of the drive motor, an actuating member is arranged in the handle, which has a pressure surface for supporting the fingers of a user's hand. In an initial position with the drive motor stopped, the actuator is with its pressure surface above the gripping surface of the handle; the actuator protrudes from the gripping surface of the handle. If the user grips the handle, several fingers rest on the pressure surface of the actuator and adjust this into an operating position for continuous operation of the rotating drive motor. This operating position for continuous operation is usually a regular, maximum operating position. In this operating position, the actuator is immersed in the handle, such that the pressure surface of the actuator is at a level with the gripping surface of the handle.

Beim Arbeiten mit derartigen Arbeitsgeräten können am Werkzeug erhöhte Lasten auftreten, die zu einem Verklemmen des Arbeitswerkzeugs führen können. Bei Blasgeräten besteht häufig der Wunsch, den Blasstrom kurzzeitig zu erhöhen, um schlecht zu lösende Gegenstände wie feuchte Blätter, feuchtes Papier oder dergleichen von einem Untergrund abzulösen.When working with such implements increased loads can occur on the tool, which can lead to jamming of the working tool. In blowers, there is often a desire to increase the blowing current for a short time to solve badly Remove objects such as damp leaves, damp paper or the like from a substrate.

Die WO 2013/122267 A1 schlägt vor, einen Regelkreis vorzusehen, über den aus einer niedrigen Akkuspannung eine erhöhte Betriebsspannung für einen elektrischen Antriebsmotor generiert wird. Über ein Wählglied ist die Höhe der Betriebsspannung und damit die Drehzahl des Antriebsmotors durch das Wählglied einstellbar. Eine Einstellung ändert allerdings nur die Leistungsabgabe in der vorgegebenen Betriebsstellung des Betätigungsgliedes. Wird im Betrieb eine erhöhte Leistungsabgabe gewünscht, muss der Benutzer das Wählglied verstellen; ist die erhöhte Leistungsabgabe nicht länger erforderlich, muss der Benutzer das Wählglied zurückdrehen. Dies ist umständlich und bedingt jeweils ein erneutes Einstellen der gewünschten Leistung.The WO 2013/122267 A1 proposes to provide a control circuit, via which a high operating voltage for an electric drive motor is generated from a low battery voltage. About a selector, the height of the operating voltage and thus the speed of the drive motor is adjustable by the selector. However, a setting only changes the power output in the predetermined operating position of the actuator. If an increased power output is desired during operation, the user must adjust the selector; If the increased power output is no longer required, the user must turn back the selector. This is cumbersome and requires in each case a new setting of the desired performance.

Der Erfindung liegt die Aufgabe zugrunde, einen Handgriff mit einem darin angeordneten Betätigungsglied derart auszubilden, dass der Benutzer in einfacher Weise eine maximale Betriebsstellung des Betätigungsgliedes für den Dauerbetrieb wählen und halten kann und darüber hinaus eine wählbare weitere Betätigungsstellung für eine erhöhte Leistungsabgabe einstellen kann.The invention has for its object to form a handle with an actuator disposed therein such that the user can easily select and hold a maximum operating position of the actuator for continuous operation and beyond can set a selectable additional operating position for increased power output.

Die Aufgabe wird erfindungsgemäß nach den Merkmalen des Anspruchs 1 gelöst.The object is achieved according to the features of claim 1.

Im Bereich des Betätigungsgliedes ist in der Grifffläche des Handgriffs eine Vertiefung ausgebildet, die sich in Längsrichtung des Handgriffs erstreckt. Die Vertiefung überlappt die Druckfläche des Betätigungsgliedes zumindest teilweise derart, dass das Betätigungsglied in eine Booststellung durch einen Finger der Benutzerhand über die Vertiefung in den Handgriff zu verlagern ist, wobei in dieser Booststellung die Druckfläche des Betätigungsgliedes innerhalb der Grifffläche des Handgriffes liegt.In the region of the actuator, a recess is formed in the gripping surface of the handle, which extends in the longitudinal direction of the handle. The depression overlaps the pressure surface of the actuator at least partially such that the actuator is to be displaced into a boost position by a user's finger over the recess in the handle, wherein in this boost position the pressure surface of the actuator is within the gripping surface of the handle.

Durch diese konstruktive Gestaltung kann der Benutzer in einfacher Weise durch übliches Umgreifen der Grifffläche des Handgriffs und Auflage seiner Finger auf die Druckfläche des Betätigungsgliedes eine maximale Betriebsstellung des Betätigungsgliedes für den Dauerbetrieb wählen und halten. Will der Benutzer eine erhöhte Leistung abrufen, kann er mit mindestens einem Finger in die Vertiefung eingreifen und das Betätigungsglied über die maximale Betriebsstellung für den Dauerbetrieb hinaus in den Handgriff verschwenken. In dieser sogenannten Booststellung liegt die Druckfläche des Betätigungsgliedes innerhalb der Grifffläche des Handgriffs; in dieser Stellung kann - z. B. über einen Zusatzschalter gesteuert - eine erhöhte Leistung des Elektromotors abgerufen werden. Zweckmäßig hat sich eine Leistungserhöhung von ca. 10% bis 30% über die Leistung in der maximalen Betriebsstellung für den Dauerbetrieb als vorteilhaft gezeigt.This constructive design allows the user to easily select and hold a maximum operating position of the actuator for continuous operation by usually embracing the handle surface of the handle and support his finger on the pressure surface of the actuator. If the user wants to retrieve increased power, he can engage with at least one finger in the depression and pivot the actuator beyond the maximum operating position for continuous operation out into the handle. In this so-called Booststellung the pressure surface of the actuator is within the gripping surface of the handle; in this position can -. B. controlled via an additional switch - an increased power of the electric motor can be accessed. Expediently, a power increase of approximately 10% to 30% over the power in the maximum operating position for continuous operation has proven to be advantageous.

Das Betätigungsglied kann auch mit einem Potentiometer gekoppelt sein, dessen Ausgangssignal einer Steuerung zur Zumessung der elektrischen Energie zugeführt ist. Sind etwa 80% bis 90% des möglichen Stellweges des Potentiometers durchlaufen, wird die Steuerung entsprechend der Booststellung des Betätigungsgliedes eine Leistungserhöhung von ca. 10% bis 30% über der Leistung in der regelmäßigen maximalen Betriebsstellung für den Dauerbetrieb zumessen.The actuator may also be coupled to a potentiometer whose output is fed to a controller for metering the electrical energy. Are about 80% to 90% of the possible travel of the potentiometer through, the controller is in accordance with the boost position of the actuator, an increase in performance from approx. 10% to 30% above the power in the regular maximum operating position for continuous operation.

Vorteilhaft weist die Vertiefung eine sich in Längsrichtung des Handgriffs erstreckende Länge auf, die kleiner ist als die sich in gleicher Richtung erstreckende Druckfläche des Betätigungsgliedes. Dabei kann die Vertiefung derart angeordnet sein, dass sie innerhalb der sich in Längsrichtung des Handgriffs erstreckenden Länge des Betätigungsgliedes liegt, d. h., dass in Seitenansicht auf den Handgriff die Vertiefung im Bereich der Druckfläche beginnt und endet.Advantageously, the recess has a length extending in the longitudinal direction of the handle, which is smaller than the pressure surface of the actuating member extending in the same direction. In this case, the recess may be arranged such that it lies within the longitudinal extent of the handle extending length of the actuator, d. h., That in side view of the handle, the depression in the area of the pressure surface begins and ends.

Die Druckfläche des Betätigungsgliedes ist durch sich in Längsrichtung des Handgriffs erstreckende Seitenflächen begrenzt, wobei die Vertiefung in der Grifffläche des Handgriffs auf beiden Seiten des Betätigungsgliedes ausgebildet ist.The pressure surface of the actuator is limited by extending in the longitudinal direction of the handle side surfaces, wherein the recess in the gripping surface of the handle is formed on both sides of the actuator.

Die Vertiefung ist konstruktiv in Längsrichtung des Handgriffs mit einer Länge ausgeführt, die der Dicke eines genormten Fingers einer genormten Benutzerhand entspricht. Vorteilhaft hat die Vertiefung eine Länge von 10 mm bis 50 mm, insbesondere eine Länge von 15 mm bis 30 mm.The recess is structurally designed in the longitudinal direction of the handle with a length corresponding to the thickness of a standard finger of a standardized user's hand. Advantageously, the recess has a length of 10 mm to 50 mm, in particular a length of 15 mm to 30 mm.

Das Betätigungsglied ist gegen die Kraft einer Feder zu verstellen. Um das Betätigungsglied aus der maximalen Betriebsstellung für den Dauerbetrieb in eine Booststellung zu verstellen, ist eine erhöhte Federkraft zu überwinden. Dadurch erfährt der Benutzer haptisch, dass er einen erhöhten Betätigungswiderstand zu überwinden hat, bevor er das Betätigungsglied in die Booststellung verschwenken kann. Dadurch ist gewährleistet, dass die Booststellung nicht unabsichtlich betätigt wird.The actuator is to be adjusted against the force of a spring. To adjust the actuator from the maximum operating position for continuous operation in a boost position, an increased spring force is overcome. As a result, the user feels haptically that he has to overcome an increased actuation resistance before he can pivot the actuator in the Booststellung. This ensures that the Booststellung is not operated unintentionally.

Die die erhöhte Federkraft bereitstellende Feder bildet zugleich einen federnden Zwischenanschlag, der die maximale Betriebsstellung für den Dauerbetrieb bestimmt.The spring providing the increased spring at the same time forms a resilient intermediate stop, which determines the maximum operating position for continuous operation.

Der Booststellung ist ein den Verstellweg des Betätigungsgliedes begrenzender Boostanschlag zugeordnet, wodurch der Verschwenkweg des Betätigungsgliedes konstruktiv begrenzt ist.The Booststellung is associated with the adjustment of the actuator limiting Boostanschlag, whereby the Verschwenkweg of the actuator is structurally limited.

Das Betätigungsglied ist vorteilhaft ein Schwenkhebel, kann aber auch ein in einer Kulisse verschiebbarer translatorisch bewegter Hebel oder dergleichen sein.The actuator is advantageously a pivot lever, but may also be a displaceable in a backdrop translationally moving lever or the like.

In das Gehäuse 6 kann ein Akkupack eingeschoben sein, der den elektrischen Antriebsmotor 2 mit Energie versorgt. Der Akkupack kann auch am Gürtel eines Benutzers getragen oder als rückengetragener Akkupack vorgesehen sein, wobei dann ein Anschlusskabel vom Akkupack zum Arbeitsgerät führt.This in Fig. 1 illustrated implement 1 is a blower with a drive motor 2, which is indicated by dashed lines. The implement 1 has an upper handle 3 which is fixed at its rear end 4 and at its front end 5 on the upper side of the housing 6 of the implement 1. An impeller driven by the drive motor 2 sucks in the direction of arrow 7 air through a protective grid and blows them out at the mouth 8 of the blower 9.

In the housing 6, a battery pack may be inserted, which supplies the electric drive motor 2 with energy. The battery pack can also be worn on the belt of a user or be provided as a back-worn battery pack, in which case a connection cable leads from the battery pack to the implement.

Zur Steuerung der Drehzahl des elektrischen Antriebsmotors 2 ist ein Betätigungsglied 10 als Schalthebel im Handgriff 3 gelagert. Im gezeigten Ausführungsbeispiel liegt das Betätigungsglied 10 nahe dem vorderen Ende 5 und ist - im Ausführungsbeispiel - als Schwenkhebel im Handgriff 3 gelagert (Fig. 4). Das Betätigungsglied 10 kann auch in anderer Weise im Handgriff angeordnet sein, z. B. über eine Kulissenführung verschiebbar sein.To control the rotational speed of the electric drive motor 2, an actuator 10 is mounted as a shift lever in the handle 3.

The actuator 10 may also be arranged in another way in the handle, z. B. be displaced via a slotted guide.

Das Betätigungsglied 10 kann zweckmäßig mit einem nicht näher dargestellten Potentiometer gekoppelt sein, dessen Ausgangssignal einer Steuerung zur Zumessung der elektrischen Energie zum Antriebsmotor 2 zugeführt ist. Die Verstellung des Potentiometers durch das Betätigungsglied erfolgt gegen die Kraft einer Feder. Die Feder wirkt derart, dass das Betätigungsglied in seine Ausgangslage zurückgestellt wird.The actuator 10 may be suitably coupled to a potentiometer, not shown, whose output signal is fed to a controller for metering the electrical energy to the drive motor 2. The adjustment of the potentiometer by the actuator takes place against the force of a spring. The spring acts such that the actuator is returned to its original position.

Im Bereich des vorderen Endes 5 des Handgriffs 3 ist ferner ein Wählschalter 11 zum elektrischen Einstellen von Gebläsestufen gelagert. In jeder gewählten Gebläsestufe wird über den Verschwenkweg des Betätigungsgliedes 10 eine Drehzahlerhöhung mit einer anderen Steigung umgesetzt.In the area of the front end 5 of the handle 3, a selector switch 11 is also mounted for the electrical adjustment of blower stages. In each selected blower stage, a speed increase with a different pitch is implemented via the Verschwenkweg of the actuator 10.

Das in den Fig. 2 bis 5 vergrößert dargestellte Betätigungsglied 10 weist eine Druckfläche 12 auf, auf der die Finger 13 einer nicht näher dargestellten Benutzerhand zu liegen kommen. In den Fig. 2 bis 5 sind jeweils der Zeigefinger 13a, der Mittelfinger 13b, der Ringfinger 13c und der kleine Finger 13d als Kreise unterschiedlichen Durchmessers angedeutet. Die Druckfläche 12 wird, wie insbesondere Fig. 3 zeigt, im Wesentlichen von dem Zeigefinger 13a und dem Mittelfinger 13b betätigt. Die Benutzerhand umgreift dabei das Griffgehäuse 14 des Handgriffs 3, dessen Oberseite eine Hüllkurve 15 bildet. Diese Hüllkurve 15 bildet zugleich die Grifffläche 16, wobei im Rahmen der Erfindung insbesondere die dem Gehäuse 6 zugewandt liegende Abschnitt der Grifffläche 16 des Handgriffs von Bedeutung ist.That in the Fig. 2 to 5 shown magnified actuator 10 has a pressure surface 12 on which come the fingers 13 of a user hand, not shown. In the Fig. 2 to 5 In each case, the index finger 13a, the middle finger 13b, the ring finger 13c and the small finger 13d are indicated as circles of different diameters. The pressure surface 12 is, as in particular Fig. 3 shows, essentially of the index finger 13a and the middle finger 13b actuated. The user's hand encompasses the handle housing 14 of the handle 3, the upper side of which forms an envelope 15. This envelope 15 at the same time forms the gripping surface 16, wherein, in particular, the portion of the gripping surface 16 of the handle facing the housing 6 is of importance in the context of the invention.

Das als Schalthebel ausgebildete Betätigungsglied 10 liegt innerhalb eines durch den Handgriff 3, seine Enden 4 und 5 und das Gehäuse 6 des Arbeitsgerätes 1 gebildeten Rahmens. Das Betätigungsglied 10 erstreckt sich in Längsrichtung des Handgriffs 3, wobei der Handgriff 3 in Richtung der Längsmittelachse 17 des Arbeitsgerätes 1 ausgerichtet liegt. Das als Schalthebel ausgebildete Betätigungsglied 10 ist insbesondere in Fig. 4 in Seitenansicht dargestellt.Trained as a shift lever actuator 10 is within a frame formed by the handle 3, its ends 4 and 5 and the housing 6 of the implement 1. The actuator 10 extends in the longitudinal direction of the handle 3, wherein the handle 3 is aligned in the direction of the longitudinal center axis 17 of the implement 1. The trained as a shift lever actuator 10 is in particular in Fig. 4 shown in side view.

Das Betätigungsglied 10 liegt unbetätigt in einer Ausgangslage 20, wie sie in Fig. 2 dargestellt ist. In dieser Ausgangslage 20 ist die Drehzahl eines elektrischen Antriebsmotors 2 "null"; der Antriebsmotor 2 steht still. In dieser Ausgangslage 20 liegt die Druckfläche 12 des Betätigungsgliedes 10 außerhalb der Hüllkurve 15; die Druckfläche 12 steht über die Grifffläche 16 vor.The actuator 10 is unconfirmed in a starting position 20, as in Fig. 2 is shown. In this starting position 20, the rotational speed of an electric drive motor 2 is "zero"; the drive motor 2 stands still. In this initial position 20, the pressure surface 12 of the actuator 10 is outside the envelope 15; the pressure surface 12 projects beyond the gripping surface 16.

In einer regelmäßigen Betriebsstellung 21 des Betätigungsgliedes 10 für einen Dauerbetrieb des Antriebsmotors 2 ist das Betätigungsglied 10 über die Druckfläche 12 von den Fingern 13a und 13b der Betätigungshand eines Benutzers in das Griffgehäuse 14 des Handgriffs 3 verlagert, wie Fig. 3 zeigt. Das Betätigungsglied 10 ist derart durch eine Aufnahmeöffnung 18 (Fig. 4) des Handgriffs 3 eingetaucht, dass die Druckfläche 12 des Betätigungsgliedes 10 auf einer Höhe H mit der Grifffläche 16 des Handgriffs 3 liegt (Fig. 3). In dieser durch die Finger 13 einer Benutzerhand betätigten Betriebsstellung wird die Druckfläche 12 im Wesentlichen von dem Zeigefinger 13a und dem Mittelfinger 13b kraftbeaufschlagt.In a regular operating position 21 of the actuator 10 for a continuous operation of the drive motor 2, the actuator 10 is displaced via the pressure surface 12 of the fingers 13 a and 13 b of the operating hand of a user in the handle housing 14 of the handle 3, as Fig. 3 shows. The actuating member 10 is in such a way by a receiving opening 18 ( Fig. 4 ) of the handle 3 immersed, that the pressure surface 12 of the actuator 10 is at a height H with the gripping surface 16 of the handle 3 ( Fig. 3 ). In this operating position actuated by the fingers 13 of a user's hand, the pressure surface 12 is essentially subjected to force by the index finger 13a and the middle finger 13b.

Die maximale Lage der regelmäßigen Betriebsstellung 21 für den Dauerbetrieb des Antriebsmotors 2 ist in Fig. 4 in einer Schnittdarstellung wiedergegeben. Das Betätigungsglied 10 ist um eine Schwenkachse 19 verschwenkbar im Bereich des vorderen Endes 5 des Handgriffs 3 gelagert; eine am verschwenkbaren Betätigungsglied 10 angreifende Rückstellfeder, die nicht näher dargestellt ist, übt eine Rückstellkraft auf das Betätigungsglied 10 aus, um es in Drehrichtung 24 in seine Ausgangsstellung 20 zurückzustellen. In Fig. 6 ist der Verlauf der Bedienkraft des Betätigungshebels als Kraftkurve 40 wiedergegeben. Das Betätigungsglied 10 ist somit gegen die Kraft einer Rückstellfeder zu verstellen.The maximum position of the regular operating position 21 for the continuous operation of the drive motor 2 is in Fig. 4 reproduced in a sectional view. The actuator 10 is pivotally mounted about a pivot axis 19 in the region of the front end 5 of the handle 3; an acting on the pivotable actuator 10 return spring, which is not shown in detail, exerts a restoring force on the actuator 10 to reset it in the direction of rotation 24 in its initial position 20. In Fig. 6 the course of the operating force of the actuating lever is shown as a force curve 40. The actuator 10 is thus to be adjusted against the force of a return spring.

Eine am freien Ende 22 des Betätigungsgliedes 10 angeordnete Feder 23, im Ausführungsbeispiel eine Blattfeder, hat an ihrem freien Ende 25 eine ausgebildete Stufe 26. An der Stufe 26 liegt ein Nocken 27 des Betätigungsgliedes 10 dann an, wenn das Betätigungsglied 10 entgegen der Drehrichtung 24 in seine maximale, regelmäßige Betriebsstellung 21 für den Dauerbetrieb verschwenkt ist. Dieses Auflaufen des Nockens 27 auf die Stufe 26 der Feder 23 ist in der Kraftkurve 40 als Kraftpeak 41 dargestellt. Läuft der Nocken 27 an die Stufe 26 an, spürt der Benutzer die erhöhte Betätigungskraft (Kraftpeak 41) und kann so feststellen, dass er die regelmäßige, maximale Betriebsstellung 21 des Betätigungsgliedes 10 für den Dauerbetrieb erreicht hat.A arranged at the free end 22 of the actuator 10 spring 23, in the embodiment, a leaf spring has at its free end 25 a trained stage 26. At the stage 26 is a cam 27 of the actuator 10 then when the actuator 10 against the direction of rotation 24th is pivoted into its maximum, regular operating position 21 for continuous operation. This emergence of the cam 27 on the step 26 of the spring 23 is shown in the force curve 40 as a power peak 41. When the cam 27 engages the step 26, the user senses the increased operating force (force peak 41) and can thus determine that he has reached the regular, maximum operating position 21 of the actuator 10 for continuous operation.

Diese maximale, regelmäßige Betriebsstellung 21 ist elektrisch derart ausgelegt, dass eine möglichst lange Betriebszeit des Arbeitsgerätes 1 mit einem angeschlossenen Akkupack erzielt wird. Dabei ist die Auslegung so getroffen, dass eine ausreichend hohe Leistung bereitgestellt ist, die für regelmäßige Arbeiten erforderlich ist. Für eine Maximalleistung des Arbeitsgerätes 1 ist dem Betätigungsglied eine Booststellung 33 zugeordnet, wie nachstehend näher ausgeführt ist.This maximum, regular operating position 21 is electrically designed such that the longest possible operating time of the implement 1 is achieved with a connected battery pack. The design is such that a sufficiently high performance is provided, which is necessary for regular work. For a maximum output of the implement 1, a boost position 33 is associated with the actuator, as explained in more detail below.

Wie den Fig. 2, 3 und 5 zu entnehmen, ist im Bereich des Betätigungsgliedes 10 in der Grifffläche 16 des Handgriffs 3 eine Vertiefung 30 ausgebildet, die sich in Längsrichtung 28 des Handgriffs 3 erstreckt. Zweckmäßig liegt auf beiden Längsseiten 29 des Betätigungsgliedes 10 eine Vertiefung 30 in der Grifffläche 16 des Handgriffs 3, so dass sich die Vertiefung quer zur Längsrichtung 28 des Handgriffs 3 erstreckt.Like that Fig. 2 . 3 and 5 can be seen, in the region of the actuator 10 in the gripping surface 16 of the handle 3, a recess 30 is formed which extends in the longitudinal direction 28 of the handle 3. Suitably lies on both longitudinal sides 29 of the actuating member 10, a recess 30 in the gripping surface 16 of the handle 3, so that the recess extends transversely to the longitudinal direction 28 of the handle 3.

Grundsätzlich ist es ausreichend, wenn die Vertiefung 30 die Druckfläche 12 des Betätigungsgliedes 10 zumindest teilweise überlappt, derart, dass das Betätigungsglied 10 in einer Booststellung 33 durch z. B. einen Finger 13a der Benutzerhand über die Vertiefung 30 weiter in den Handgriff 3 verlagert werden kann. Das Betätigungsglied 10 kann somit über die maximale Betriebsstellung für den Dauerbetrieb hinaus in die Booststellung 33 verschwenkt werden, in der die Druckfläche 12 des Betätigungsgliedes 10 innerhalb der Hüllkurve 15 des Handgriffes 3 liegt, also innerhalb der Grifffläche 16 des Handgriffes 3. Dies ist in Fig. 5 dargestellt. Der Benutzer kann durch Eingriff z. B. des Zeigefingers 13a in die Vertiefung 30 das Betätigungsglied 10 in die Booststellung 33 verschwenken; in dieser Booststellung 33 ist die Drehzahl des Antriebsmotors 2 signifikant erhöht, z. B. um bis zu 30% gegenüber der Drehzahl in der maximalen, regelmäßigen Betriebsstellung 21 für den Dauerbetrieb (Fig. 3) erhöht. Die entsprechende Drehzahlkurve 50 ist in Fig. 6 dargestellt.In principle, it is sufficient if the recess 30 at least partially overlaps the pressure surface 12 of the actuating member 10, such that the actuating member 10 in a boost position 33 by z. B. a finger 13a of the user's hand on the recess 30 can be moved further into the handle 3. The actuator 10 can thus be pivoted beyond the maximum operating position for continuous operation in the Booststellung 33, in which the pressure surface 12 of the actuator 10 is within the envelope 15 of the handle 3, ie within the gripping surface 16 of the handle 3. This is in Fig. 5 shown. The user can by intervention z. B. the index finger 13a pivot into the recess 30, the actuator 10 in the Booststellung 33; in this boost position 33, the rotational speed of the drive motor 2 is significantly increased, for. B. by up to 30% compared to the speed in the maximum, regular operating position 21 for continuous operation ( Fig. 3 ) elevated. The corresponding speed curve 50 is in Fig. 6 shown.

Im gezeigten Ausführungsbeispiel hat die Vertiefung 30 eine in Längsrichtung 28 des Handgriffes 3 gemessene Länge L (Fig. 2), die kleiner ist als die sich in gleicher Richtung erstreckende Länge D der Druckfläche 12 des Betätigungsgliedes 10. Die Anordnung in Längsrichtung 28 des Handgriffes 3 ist ferner so vorgesehen, dass die Vertiefung 30 innerhalb der sich in Längsrichtung 28 des Handgriffs 3 erstreckenden Länge D der Druckfläche 12 des Betätigungsgliedes 10 liegt. Dabei ist die Anordnung so getroffen, dass die Vertiefung 30 in der Grifffläche 16 des Handgriffs 3 auf beiden Seitenflächen 29 des Betätigungsgliedes 10 ausgebildet ist, wobei die beiden sich parallel zur Längsrichtung 28 des Handgriffs erstreckenden Seitenflächen 29 des Betätigungsgliedes 10 die Druckfläche 12 seitlich begrenzen.In the embodiment shown, the recess 30 has a length L measured in the longitudinal direction 28 of the handle 3 (FIG. Fig. 2 The arrangement in the longitudinal direction 28 of the handle 3 is further provided so that the recess 30 within the extending in the longitudinal direction 28 of the handle 3 Length D the pressure surface 12 of the actuator 10 is located. The arrangement is such that the recess 30 is formed in the gripping surface 16 of the handle 3 on both side surfaces 29 of the actuator 10, the two parallel to the longitudinal direction 28 of the handle extending side surfaces 29 of the actuator 10, the pressure surface 12 laterally limit.

Die in Längsrichtung 28 sich erstreckende Länge L der Vertiefung 30 entspricht zumindest der Dicke eines Fingers 13 einer typischen Benutzerhand. Konstruktiv ist vorgesehen, dass die Vertiefung eine Länge L von 10 mm bis 50 mm hat, derart, dass eine große Anzahl von Benutzern mit der Benutzerhand bzw. einem oder zwei Fingern 13 der Benutzerhand das Betätigungsglied 10 über die Vertiefung 30 in die Booststellung 33 verlagern können. Die Länge L kann so vorgesehen sein, dass nur ein Finger - z. B. der Zeigefinger 13a - die Booststellung 33 des Betätigungsgliedes 10 auslösen kann, wozu eine Länge von 15 mm bis 30 mm vorteilhaft ist. Es kann zweckmäßig sein, die Länge bis zu 50 mm auszudehnen, damit zwei Finger des Benutzers gleichzeitig in die Vertiefung 30 eintauchen können, um das Betätigungsglied 10 in die Booststellung 33 zu verstellen.The length L of the recess 30 extending in the longitudinal direction 28 corresponds at least to the thickness of a finger 13 of a typical user's hand. It is structurally provided that the recess has a length L of 10 mm to 50 mm, such that a large number of users with the user's hand or one or two fingers 13 of the user's hand move the actuator 10 via the recess 30 in the Booststellung 33 can. The length L may be provided so that only one finger -. B. the index finger 13a - Boost position 33 of the actuator 10 can trigger what a length of 15 mm to 30 mm is advantageous. It may be appropriate to extend the length up to 50 mm, so that two fingers of the user can simultaneously dive into the recess 30 to adjust the actuator 10 in the Booststellung 33.

Der Übergang von der maximalen Betriebsstellung 21 für den Dauerbetrieb gemäß den Fig. 3 und 4 in die Booststellung 33 gemäß Fig. 5 kann nur unter Überwindung einer erhöhten Federkraft erreicht werden. Fig. 6 gibt dieses deutlich wieder. Erst nach Überwinden des Kraftpeaks steigt die Drehzahl um bis zu 30% an.The transition from the maximum operating position 21 for continuous operation according to the 3 and 4 in the boost position 33 according to Fig. 5 can only be achieved by overcoming an increased spring force. Fig. 6 reproduces this clearly. Only after overcoming the force peak, the speed increases by up to 30%.

Um eine definierte Endlage des Betätigungsgliedes 10 in der Booststellung 33 zu erreichen, ist vorgesehen, innerhalb des Griffgehäuses 14 einen Boostanschlag 31 vorzusehen, der das Ende des Verstellweges des Betätigungsgliedes 10 festlegt.In order to achieve a defined end position of the actuator 10 in the boost position 33, it is provided to provide a boost stop 31 within the handle housing 14, which determines the end of the adjustment of the actuator 10.
