Definitions
- the invention relates to a working device with an internal combustion engine of the type specified in the preamble of claim 1.
- a working device namely a power saw known, which has a starting device.
- a connection between a throttle holding part of the starting device and the braking device is provided.
- the braking device is actuated and adjusted to the braked position.
- the invention has for its object to provide a working device with an internal combustion engine of the generic type, in which it is ensured in a simple manner that the tool is not driven when starting the implement.
- a blocking device is provided with a pawl which projects in an actuated position in the path of movement of the driven element and limits the rotation of the driven element to less than one revolution.
- the starting device has an actuating device for the blocking device. In the starting position of the starting device, the blocking device holds the pawl in the actuated position. Since the output element in start position the starting device is blocked by the pawl, the output element of the clutch can not rotate. As a result, a drive of the tool is prevented in a simple manner.
- a pawl can securely lock the output element and absorb relatively large forces.
- the blocking device can be structurally simple, resulting in a simple construction of the implement. Since the starting means for starting the internal combustion engine is moved to the starting position, the internal combustion engine does not run when adjusting the pawl in the actuated position, and the forces exerted by the output member on the pawl forces are low.
- the blocking device is advantageously adjusted when inserting the starting position in the actuated position.
- the actuating movement when inserting the starting position is therefore used to adjust the blocking device in the actuated position.
- the pawl is in particular pivotally mounted. This results in a simple structure, and for adjusting the pawl in the actuated position only low actuation forces are required.
- the pawl is advantageously spring-loaded by a return spring in the direction of the unactuated position of the blocking device.
- the starting device adjusts the pawl, in particular against the force of the return spring in the actuated position.
- the return spring ensures that the pawl can be returned to the unactuated position when the starting position is in its operative position.
- the reset of the starting device in the operating position and the reset of the pawl can be done independently due to the return spring.
- the connection between the actuating device and the pawl is designed so that the actuating device can adjust the pawl only in the direction of the actuated position. The movement of the actuator back into the operating position of the starting device associated position advantageously causes no provision of the pawl.
- a damping spring is arranged in operative connection between the actuating device and the pawl.
- the damping spring dampens the contact of the Pawl with the output member when the actuator is moved to the starting position while the output member is already rotating.
- the damper spring also allows for adjustment of the actuator even if the pawl can not be adjusted to the actuated position. This is especially the case when the pawl is blocked by the output element itself, for example due to an unfavorable rotational position of the output element.
- the pawl applies in this case under bias to the output element. As soon as the output element begins to rotate and moves out of the rotational position, the pawl can be pivoted into its actuated position, so that further rotation of the output element is avoided. Even with unfavorable rotational position of the output element is thereby prevented that the output member can rotate more than one revolution.
- the blocking device has a holding contour which holds the pawl in the drive direction loaded output element regardless of the position of the starting device in the actuated position.
- To reset the pawl in the unactuated position is therefore also necessary in addition to the adjustment of the locking device in the operating position that the output element is not loaded in the drive direction. This prevents a jerky acceleration of the tool when releasing the starting device.
- the pawl remains in its actuated position. Only when the output element is not loaded in the drive direction, the pawl can be adjusted back into its actuated position in particular due to the force of the return spring. Instead of the return spring, the pawl can also be reset by the operator.
- a simple constructive structure is obtained when the pawl cooperates in blocking the output element with a receptacle of the output element.
- the output element in particular has a plurality of rotationally symmetrical to the axis of rotation of the driven element arranged recordings. As a result, the possible rotational movement of the output element can be limited to significantly less than one revolution of the output element. Two recordings have proved to be particularly advantageous.
- the blocking device blocks an insertion of the starting position with a rotating output element.
- inserting the starting position during operation that is to say when the internal combustion engine is running, can be avoided in a simple manner.
- a simple design results when the blocking device has a non-rotatably connected to the output element blocking contour, the force at a rotating output element and from the unactuated position in the direction of their actuated position pawl above a design predetermined speed, a force on the pawl towards her unconfirmed position.
- a simple construction results when the locking contour is adjacent to the receptacle on the outer side and the rearward direction of the receptacle relative to the axis of rotation. The locking contour is in particular firmly connected to the output element.
- the blocking contour is advantageously arranged on the outside of the axis of rotation and on the outside in the drive direction of the receptacle adjacent to the receptacle. This results in a simple structural design.
- the locking contour is formed on a driven element held on the flyweight, which covers the recording at speeds above the design predetermined rotational speed at least partially. The recording is at least so far covered that the pawl can not be adjusted to its actuated position or is held by the retaining contour is not in the actuated position.
- the starting position of the starting device is advantageously achieved by actuating a throttle lever of the working device.
- the pawl can still remain in its actuated position.
- the clutch is in particular a centrifugal clutch, and the output member comprises a clutch drum.
- Fig. 1 shows as an exemplary embodiment of a working device with an internal combustion engine, a hand-held working device, namely a power saw 1.

- a choke lever 31 is fixed.
- the choke lever 31 may be rotatably connected to the choke shaft 29, as shown in the embodiment. For tolerance compensation, however, a small relative movement between the choke lever 31 and the choke shaft 29 may be possible.
- the mode selector 10 is coupled to the choke lever 31 via a coupling rod 36.
- the mode selector 10 is pivotally mounted about a pivot axis 50.
- the mode selector 10, the coupling rod 36, the choke lever 31, the choke shaft 29 and the choke flap 27 are part of a starting device 39.
- the choke flap 27 reduces the flow cross-section in the intake passage section 25 not or only slightly.
- the choke flap 27 is approximately parallel to the flow direction in the intake passage section 25.
- the throttle valve 26 is slightly open and the choke flap 27 against the operating position 35 further closed.
- Throttle valve 26 and choke flap 27 are in a position in which the amount of combustion air supplied to the internal combustion engine 11 and the quantity of fuel supplied to the internal combustion engine 11 are adjusted to the air consumption and the fuel consumption when the internal combustion engine 11 is started, that is to say when the starting device 21 is actuated , It can also be provided that only the choke lever 31 must be actuated and this provides the throttle lever 30 in a starting position.
- the blocking device 43 comprises a pawl 44, which is mounted pivotably about a pivot axis 58 and which cooperates with a receptacle 53 on the output element 51.
- the output element 51 comprises a clutch drum 14. On the clutch drum 14, a holding plate 52 is fixed, which protrudes on opposite sides over the outer circumference of the clutch drum 14 and which has a receptacle 53 for the pawl 44 on both sides. Also, another constructive arrangement of one or more receptacles 53 may be advantageous.
- the output element 51 is driven by the internal combustion engine 11 in a drive direction 54.
- FIG. 5 shows the pawl 44 in its actuated position 46. In this position, the pawl 44 projects into the in Fig. 5 Dashed line of movement 71 of the output element 51 a.
- the movement path 71 is the circle which the region of the output element 51 furthest from the rotation axis 41 describes in the region of the receptacle 53 when rotating about the rotation axis 41.
- the actuating element 57 engages.
- the actuating element 57 is of a return spring 55 in the direction of a in Fig. 7 shown unactuated position 47 of the pawl 44 spring-loaded.
- the return spring 55 is supported at one end on a fixed bearing 56 connected to the actuator 57.
- the other end of the spring 55 is fixedly connected to the housing 2.
- the mode selector 10 is firmly connected in the exemplary embodiment with a bearing shaft 48 and pivotally mounted about the pivot axis 50. On the bearing shaft 48, an actuating pin 49 is fixed, which acts on the actuating element 57.
- the mode selector 10 forms with the bearing shaft 48 and the actuating pin 49, an actuator 45 for the blocking device 43rd Fig. 5 shows the mode selector 10 in its starting position 80.
- the starting device 39 In the starting position 80 of the mode selector 10, the starting device 39 is in its starting position 42 (FIG. Fig. 4 ).
- the actuating pin 49 presses the pawl 44 against the force of the spring 55 in the actuated position 46th
- the mode selector 10 is due to the force of a spring not shown in his in Fig. 6 shown operating position 81 adjusted. It can also be provided that the mode selector 10 is selected by the operator from the in Fig. 5 Starting position shown 80 in the in Fig. 6 shown operating position 81 is reset.
- a holding contour 59 is formed on the receptacle 53. The holding contour 59 limits the receptacle 53 on the radially outside of the axis of rotation 41 and in the drive direction 54 behind the area and lies in the pivoting path of the pawl 44 from the actuated position 46 in the in Fig.
- Fig. 7 shows the arrangement after the output element 51 is no longer loaded in the drive direction 54. This can be done, for example, that the operator releases the throttle lever 8 and the engine 11 is operated at idle. The idle speed is below the engagement speed of the clutch 13, so that the output element 51 of the clutch 13 is not driven further. Due to the force of the spring 55, the pawl 44 is pivoted in a pivoting direction 65 in its unactuated position 57. In this case, the pawl 44 has exerted a force on the retaining contour 59 and the output element 51 slightly in a direction of drive 54 54 opposite direction of rotation moves. The retaining contour 59 causes the pawl 44 remains in its actuated position 46, to the output element 51 no torque in the drive direction 54 acts more. As a result, jerky starting of the tool when adjusting the starting device 39 into the operating position 35 can be prevented.
- a locking contour 60 is formed on the receptacle 53 adjacent to the retaining contour 59.
- the blocking contour 60 is arranged on the side of the receptacle 53, which lies radially on the outside relative to the axis of rotation 41 and on the rear side relative to the drive direction 54, adjacent to the receptacle 53.
- the blocking contour 60 exerts in the drive direction 54 rotating output element 51 on a from the unactuated position 47 in the direction of their actuated position 46 ( Fig. 6 ) moved pawl 44 a force in the direction of the arrow 72, ie, relative to the axis of rotation 41 radially outward.
- flyweights 61 are mounted on the output member 51.
- the receptacles 53 In the in Fig. 9 shown outwardly adjusted position of the flyweights 61 close the centrifugal weights 61, the receptacles 53 at least partially.
- the receptacles 53 are approximately completely closed.
- the flyweights 61 each have a locking contour 62 which closes a receptacle 53.
- an adjustment of the pawl 44 in the in Fig. 6 shown actuated position 46 prevents.
- the centrifugal weights 61 are connected via a respective bolt 74 with the holding plate 52, which projects into a groove 73.
- the groove 73 extends inclined to the radial direction to the rotation axis 41.
- Fig. 10 shows an embodiment of a blocking device 43.
- the design of the output element 51 corresponds to the design of the output element of the Fig. 5 to 7 , Also a design according to the embodiment according to Fig. 8 or according to the embodiment according to Fig. 9 with a locking contour 60 or 62 may be advantageous.
- Like reference numerals indicate corresponding elements throughout the figures.
- the actuator 45 of in Fig. 10 embodiment shown instead of a mode selector 10 has a rotatably mounted about the pivot axis 50 knob 67.
- the knob 67 in addition to its rotational movement in the direction of the pivot axis 50 is longitudinally displaceable.
- a cantilevered arm 75 is arranged, on which one end of a damping spring 68 is fixed. The other end of the damping spring 68 is connected to the pawl 44.
- the damping spring 68 is designed as a tension spring. Also, another structural arrangement and design of acting between the knob 67 and the pawl 44 damping spring 68 may be advantageous.
- Fig. 10 is the pawl 44 in the actuated position 46. The knob 67 is in the starting position 80. If the output element 51 in Drive direction 54 driven so hooks the pawl 44 into the receptacle 53 and thereby prevents further rotation of the receptacle 53. The output element 51 is locked. This is in Fig. 11 shown.
- the pawl 44 can pivot into its actuated position 46 due to the force of the spring 68. As a result, in each rotational position of the output element 51, the adjustment of the starting device 39 into the starting position 42 is possible.
- FIGS. 14 to 17 an embodiment is shown in which both a damping spring 68 and a return spring 55 are provided.
- a first actuator 76 is fixed, which in the in Fig. 14 shown starting position 80 of the knob 67 rests against a second actuating element 77.
- the first actuator 76 and the second actuator 77 are only adjacent to each other, so that between the actuators 76 and 77 only compressive forces but no tensile forces can be transmitted.
- the second actuating element 77 acts via the damping spring 68 on the pawl 44, which in Fig. 14 is arranged in its actuated position 46. Between the second actuating element 77 and the housing 2 or an element connected to the housing 2, the return spring 55 acts.
- Fig. 15 shows the arrangement for a rotation of the output element 51 in the drive direction 54.
- the pawl 44 abuts the receptacle 53 on the output element 51, thereby blocking further rotation of the output element 51.
- the fact that two receptacles 53 are arranged opposite each other, can the output member 51 in the actuated position 46 of the pawl 44 to turn at most almost 180 ° until the pawl 44 comes into contact with a receptacle 53 and thereby blocks the output member 51.
- the knob 67 from the in Fig. 15 Starting position shown 80 in the in Fig. 16 shown operating position 81 is set, the first actuator 76 is reset.
- the second actuator 77 may follow the movement of the first actuator 76 or may perform less or no travel.
- the pawl 44 is in its actuated position 46, since it is fixed by the locking contour 59 as long as the output element 51 is driven in the drive direction 54. Once the output element 51 is no longer driven in the drive direction 54, the pawl 44 is due to the force of the springs 68 and 55 in the in Fig. 17 shown unactuated position 47 back. In this case, the drive element 51 is rotated in an opposite direction 64 until the pawl 44 is released.
- the starting device 39 can be reset regardless of the position of the pawl 44 from the starting position 80 in the operating position 81. Due to the decoupling of the two actuating elements 76 and 77, the damping spring 68 exerts no force on the rotary knob 67 even when the pawl 44 is in its actuated position 46. As a result, the release of the starting position 42 of the starting device 39 by the blocking device 43 is not with special needs.
- the blocking device 43 comprises the receptacle 53, the pawl 44 and the actuating elements 76, 77, 57 and springs 55, 68 arranged in operative connection between the pawl 44 and the mode selector 10 or the rotary knob 67.

Der Erfindung liegt die Aufgabe zugrunde, ein Arbeitsgerät mit einem Verbrennungsmotor der gattungsgemäßen Art anzugeben, bei dem auf einfache Weise sichergestellt ist, dass das Werkzeug beim Starten des Arbeitsgeräts nicht angetrieben wird.The invention has for its object to provide a working device with an internal combustion engine of the generic type, in which it is ensured in a simple manner that the tool is not driven when starting the implement.
Diese Aufgabe wird durch ein Arbeitsgerät mit einem Verbrennungsmotor mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a working device with an internal combustion engine with the features of
Um auf einfache Weise sicherzustellen, dass das Werkzeug nicht mitlaufen kann, ist eine Blockiereinrichtung mit einer Sperrklinke vorgesehen, die in einer betätigten Stellung in den Bewegungsweg des Abtriebselements ragt und die Drehung des Abtriebselements auf weniger als eine Umdrehung begrenzt. Die Starteinrichtung besitzt eine Betätigungseinrichtung für die Blockiereinrichtung. In Startstellung der Starteinrichtung hält die Blockiereinrichtung die Sperrklinke in der betätigten Stellung. Da das Abtriebselement in Startstellung der Starteinrichtung von der Sperrklinke blockiert ist, kann das Abtriebselement der Kupplung nicht mitrotieren. Dadurch ist auf einfache Weise ein Antrieb des Werkzeugs verhindert. Eine Sperrklinke kann das Abtriebselement sicher sperren und vergleichsweise große Kräfte aufnehmen. Die Blockiereinrichtung kann konstruktiv einfach aufgebaut werden, so dass sich ein einfacher Aufbau des Arbeitsgeräts ergibt. Da die Starteinrichtung zum Starten des Verbrennungsmotors in die Startstellung verstellt wird, läuft der Verbrennungsmotor beim Verstellen der Sperrklinke in die betätigte Stellung nicht, und die vom Abtriebselement auf die Sperrklinke ausgeübten Kräfte sind gering.To ensure in a simple manner that the tool can not run, a blocking device is provided with a pawl which projects in an actuated position in the path of movement of the driven element and limits the rotation of the driven element to less than one revolution. The starting device has an actuating device for the blocking device. In the starting position of the starting device, the blocking device holds the pawl in the actuated position. Since the output element in start position the starting device is blocked by the pawl, the output element of the clutch can not rotate. As a result, a drive of the tool is prevented in a simple manner. A pawl can securely lock the output element and absorb relatively large forces. The blocking device can be structurally simple, resulting in a simple construction of the implement. Since the starting means for starting the internal combustion engine is moved to the starting position, the internal combustion engine does not run when adjusting the pawl in the actuated position, and the forces exerted by the output member on the pawl forces are low.
Die Blockiereinrichtung wird vorteilhaft beim Einlegen der Startstellung in die betätigte Stellung verstellt. Die Betätigungsbewegung beim Einlegen der Startstellung wird demnach genutzt, um die Blockiereinrichtung in die betätigte Stellung zu verstellen. Die Sperrklinke ist insbesondere schwenkbar gelagert. Dadurch ergibt sich ein einfacher Aufbau, und zum Verstellen der Sperrklinke in die betätigte Stellung werden nur geringe Betätigungskräfte benötigt.The blocking device is advantageously adjusted when inserting the starting position in the actuated position. The actuating movement when inserting the starting position is therefore used to adjust the blocking device in the actuated position. The pawl is in particular pivotally mounted. This results in a simple structure, and for adjusting the pawl in the actuated position only low actuation forces are required.
Die Sperrklinke ist vorteilhaft von einer Rückstellfeder in Richtung auf die unbetätigte Stellung der Blockiereinrichtung federbelastet. Die Starteinrichtung verstellt die Sperrklinke insbesondere entgegen der Kraft der Rückstellfeder in die betätigte Stellung. Die Rückstellfeder stellt sicher, dass die Sperrklinke in die unbetätigte Stellung zurückgestellt werden kann, wenn die Startstellung sich in ihrer Betriebsstellung befindet. Das Zurückstellen der Starteinrichtung in die Betriebsstellung und das Zurückstellen der Sperrklinke können dabei aufgrund der Rückstellfeder unabhängig voneinander erfolgen. Vorteilhaft ist die Verbindung zwischen der Betätigungseinrichtung und der Sperrklinke so ausgebildet, dass die Betätigungseinrichtung die Sperrklinke nur in Richtung auf die betätigte Stellung verstellen kann. Die Bewegung der Betätigungseinrichtung zurück in die der Betriebsstellung der Starteinrichtung zugeordneten Stellung bewirkt vorteilhaft keine Rückstellung der Sperrklinke.The pawl is advantageously spring-loaded by a return spring in the direction of the unactuated position of the blocking device. The starting device adjusts the pawl, in particular against the force of the return spring in the actuated position. The return spring ensures that the pawl can be returned to the unactuated position when the starting position is in its operative position. The reset of the starting device in the operating position and the reset of the pawl can be done independently due to the return spring. Advantageously, the connection between the actuating device and the pawl is designed so that the actuating device can adjust the pawl only in the direction of the actuated position. The movement of the actuator back into the operating position of the starting device associated position advantageously causes no provision of the pawl.
Vorteilhaft ist in Wirkverbindung zwischen der Betätigungseinrichtung und der Sperrklinke eine Dämpfungsfeder angeordnet. Die Dämpfungsfeder dämpft den Kontakt der Sperrklinke mit dem Abtriebselement, wenn die Betätigungseinrichtung in die Startstellung verstellt wird, während sich das Abtriebselement bereits dreht. Die Dämpfungsfeder lässt außerdem ein Verstellen der Betätigungseinrichtung auch dann zu, wenn die Sperrklinke nicht in die betätigte Stellung verstellt werden kann. Dies ist insbesondere dann der Fall, wenn die Sperrklinke vom Abtriebselement selbst blockiert wird, beispielsweise aufgrund einer ungünstigen Drehstellung des Abtriebselements. Die Sperrklinke legt sich in diesem Fall unter Vorspannung an das Abtriebselement an. Sobald das Abtriebselement beginnt zu rotieren und sich aus der Drehstellung bewegt, kann die Sperrklinke in ihre betätigte Stellung verschwenkt werden, so dass eine weitere Rotation des Abtriebselements vermieden ist. Selbst bei ungünstiger Drehlage des Abtriebselements ist dadurch verhindert, dass sich das Abtriebselement um mehr als eine Umdrehung drehen kann.Advantageously, a damping spring is arranged in operative connection between the actuating device and the pawl. The damping spring dampens the contact of the Pawl with the output member when the actuator is moved to the starting position while the output member is already rotating. The damper spring also allows for adjustment of the actuator even if the pawl can not be adjusted to the actuated position. This is especially the case when the pawl is blocked by the output element itself, for example due to an unfavorable rotational position of the output element. The pawl applies in this case under bias to the output element. As soon as the output element begins to rotate and moves out of the rotational position, the pawl can be pivoted into its actuated position, so that further rotation of the output element is avoided. Even with unfavorable rotational position of the output element is thereby prevented that the output member can rotate more than one revolution.
Vorteilhaft besitzt die Blockiereinrichtung eine Haltekontur, die die Sperrklinke bei in Antriebsrichtung belastetem Abtriebselement unabhängig von der Stellung der Starteinrichtung in betätigter Stellung hält. Zum Rückstellen der Sperrklinke in die unbetätigte Stellung ist demnach neben der Verstellung der Sperreinrichtung in die Betriebsstellung auch notwendig, dass das Abtriebselement nicht in Antriebsrichtung belastet ist. Dadurch wird ein ruckartiges Beschleunigen des Werkzeugs beim Lösen der Starteinrichtung verhindert. Solange das Abtriebselement in Antriebsrichtung belastet ist, bleibt die Sperrklinke in ihrer betätigten Stellung. Erst wenn das Abtriebselement in Antriebsrichtung nicht belastet ist, kann die Sperrklinke insbesondere aufgrund der Kraft der Rückstellfeder zurück in ihre betätigte Stellung verstellt werden. Anstatt über die Rückstellfeder kann die Sperrklinke auch vom Bediener selbst zurückzustellen sein. Aufgrund der Haltekontur muss der Bediener nach dem Verstellen der Starteinrichtung in die Betriebsstellung zunächst eine Drehzahl unterhalb der Einkuppeldrehzahl, insbesondere die Leerlaufdrehzahl einstellen, damit die Sperrklinke in ihre unbetätigte Stellung zurückgestellt wird bzw. zurückgestellt werden kann. Erst dann ist das Abtriebselement freigegeben, und das Arbeitsgerät kann in üblicher Weise betrieben werden.Advantageously, the blocking device has a holding contour which holds the pawl in the drive direction loaded output element regardless of the position of the starting device in the actuated position. To reset the pawl in the unactuated position is therefore also necessary in addition to the adjustment of the locking device in the operating position that the output element is not loaded in the drive direction. This prevents a jerky acceleration of the tool when releasing the starting device. As long as the output element is loaded in the drive direction, the pawl remains in its actuated position. Only when the output element is not loaded in the drive direction, the pawl can be adjusted back into its actuated position in particular due to the force of the return spring. Instead of the return spring, the pawl can also be reset by the operator. Due to the holding contour of the operator after adjusting the starting device in the operating position initially set a speed below the Einkuppeldrehzahl, in particular the idle speed, so that the pawl is returned to its unactuated position or can be reset. Only then is the output element released, and the implement can be operated in the usual way.
Ein einfacher konstruktiver Aufbau ergibt sich, wenn die Sperrklinke beim Blockieren des Abtriebselements mit einer Aufnahme des Abtriebselements zusammenwirkt. Das Abtriebselement besitzt insbesondere mehrere rotationssymmetrisch zur Drehachse des Abtriebselements angeordnete Aufnahmen. Dadurch kann die mögliche Drehbewegung des Abtriebselements auf deutlich weniger als eine Umdrehung des Abtriebselements begrenzt werden. Als besonders vorteilhaft haben sich zwei Aufnahmen erwiesen.A simple constructive structure is obtained when the pawl cooperates in blocking the output element with a receptacle of the output element. The output element in particular has a plurality of rotationally symmetrical to the axis of rotation of the driven element arranged recordings. As a result, the possible rotational movement of the output element can be limited to significantly less than one revolution of the output element. Two recordings have proved to be particularly advantageous.
Vorteilhaft blockiert die Blockiereinrichtung ein Einlegen der Startstellung bei rotierendem Abtriebselement. Dadurch kann auf einfache Weise ein Einlegen der Startstellung im Betrieb, also bei laufendem Verbrennungsmotor, vermieden werden. Eine einfache Gestaltung ergibt sich, wenn die Blockiereinrichtung eine drehfest mit dem Abtriebselement verbundene Sperrkontur besitzt, die bei rotierendem Abtriebselement und bei aus der unbetätigten Stellung in Richtung auf ihre betätigte Stellung bewegter Sperrklinke oberhalb einer konstruktiv vorgegebenen Drehzahl eine Kraft auf die Sperrklinke in Richtung auf ihre unbetätigte Stellung ausübt. Ein einfacher Aufbau ergibt sich, wenn die Sperrkontur an der bezogen auf die Drehachse außen und in Antriebsrichtung hinten liegenden Seite der Aufnahme an die Aufnahme angrenzt. Die Sperrkontur ist dabei insbesondere fest mit dem Abtriebselement verbunden. Bei Drehzahlen oberhalb der konstruktiv vorgegebenen Drehzahl übt die Sperrkontur auf die Sperrklinke eine Kraft in Richtung auf die unbetätigte Stellung der Sperrklinke aus. Die Sperrkontur ist vorteilhaft an der bezogen auf die Drehachse außen und in Antriebsrichtung hinten liegenden Seite der Aufnahme angrenzend an die Aufnahme angeordnet. Dadurch ergibt sich ein einfacher konstruktiver Aufbau. Um die Drehzahl, bei der die Sperrkontur wirksam wird, weitgehend frei konstruktiv vorgeben zu können, kann auch vorgesehen sein, dass die Sperrkontur an einem am Abtriebselement gehaltenen Fliehgewicht ausgebildet ist, das die Aufnahme bei Drehzahlen oberhalb der konstruktiv vorgegebenen Drehzahl mindestens teilweise abdeckt. Die Aufnahme wird dabei mindestens so weit abgedeckt, dass die Sperrklinke nicht in ihre betätigte Stellung verstellt werden kann oder von der Haltekontur nicht in der betätigten Stellung gehalten wird.Advantageously, the blocking device blocks an insertion of the starting position with a rotating output element. As a result, inserting the starting position during operation, that is to say when the internal combustion engine is running, can be avoided in a simple manner. A simple design results when the blocking device has a non-rotatably connected to the output element blocking contour, the force at a rotating output element and from the unactuated position in the direction of their actuated position pawl above a design predetermined speed, a force on the pawl towards her unconfirmed position. A simple construction results when the locking contour is adjacent to the receptacle on the outer side and the rearward direction of the receptacle relative to the axis of rotation. The locking contour is in particular firmly connected to the output element. At speeds above the design predetermined speed exerts the locking contour on the pawl a force in the direction of the unactuated position of the pawl. The blocking contour is advantageously arranged on the outside of the axis of rotation and on the outside in the drive direction of the receptacle adjacent to the receptacle. This results in a simple structural design. To the speed at which the locking contour is effective, largely free to provide design, can also be provided that the locking contour is formed on a driven element held on the flyweight, which covers the recording at speeds above the design predetermined rotational speed at least partially. The recording is at least so far covered that the pawl can not be adjusted to its actuated position or is held by the retaining contour is not in the actuated position.
Die Startstellung der Starteinrichtung wird vorteilhaft durch Betätigen eines Gashebels des Arbeitsgeräts gelöst. Die Sperrklinke kann dabei noch in ihrer betätigten Stellung verbleiben. Die Kupplung ist insbesondere eine Fliehkraftkupplung, und das Abtriebselement umfasst eine Kupplungstrommel.The starting position of the starting device is advantageously achieved by actuating a throttle lever of the working device. The pawl can still remain in its actuated position. The clutch is in particular a centrifugal clutch, and the output member comprises a clutch drum.
