  • Fig. 2 is a section of the motor chain saw 1 in the area of the operating lever 13 and rear handle 4 shown enlarged. It can be seen that in the motor housing 2 pivotally mounted operating lever 13 in the three positions “0", “I” and “Start” is adjustable. For the start is the symbol of the clockwise rotated arrow. The position “0” means “off / service", ie the ignition is switched off.
  • the operating lever 13 may be mechanically connected to the throttle valve and the choke flap of a carburettor. As an alternative, however, electromechanical actuating means may also be considered. However, it is important that in position "0" the throttle valve is closed and the choke flap is open.
  • the position “I” means “operation”, with the ignition switched on and the throttle valve controlled according to the user and the choke flap open.
  • start In the position with the twisted arrow, which means “start”, the starting process is initiated, with the ignition is turned on, the throttle is turned on and the choke flap is closed or close and an electrical signal is given to a control unit, which is the process the starting process for the drive motor of the motor chain saw controls.
  • a control unit which is the process the starting process for the drive motor of the motor chain saw controls.
  • the electrical signal to the control unit only takes place and also the starting process is continued only when a corresponding locking device is activated for the throttle and thus ensures that during the starting operation no actuation of the throttle lever 7 takes place.
  • the Fig. 3 shows a schematic representation of the control lever positions, wherein the operating lever 13 is mounted on a Einhebelwelle 14 and pivotable about the axis of rotation.
  • the operating lever 13 is in its uppermost position "0" in the stop position at an angular position of 0 °. It is, for example, a latching position, ie the operating lever 13 remains in this position until an actuating force acts on him.
  • the operating lever can be pivoted down about the axis of rotation of the Einhebelwelle 14, wherein after a shown in the embodiment angle of 30 °, the operating lever 13 'at position "I” assumes the "operating" position, which is also is a resting position. From the position "I", the operating lever 13 can be pivoted upwards, the position "0” is initially actuated groping, with further pivoting of the operating lever 13 finally remains in the latching position "0".
  • the operating lever can be further pivoted down to the position with the rotated arrow, whereby the starting process of the engine can be initiated.
  • the operating lever 13 "assumes the position pivoted by an angle of 55 ° with respect to the position" 0. "The starting position is a momentary position, ie the operating lever 13" remains in this position only as long as a corresponding actuation the operator thus holds the operating lever 13 ", then returns to the operating position" I "by the force of a return spring, as indicated by the reference numeral 13 '.
  • the Fig. 4 shows the functional principle of the electric start system for the in Fig. 1

  • the choke flap When you release the control lever 13 is opened again, as this is returned to the operating position.
  • the ignition In the "0" position, the ignition is switched off, ie a device 16 for fuel supply and valve control and an engine control unit 17 are switched off.
  • the valve control can be done via an M-Tronik. In such a control, an electronic comparison between the starting conditions and the machine state is possible.
  • the ignition In the position "I" of the operating lever 13 13, the ignition is turned on and thus both the means 16 for fuel supply and valve control and the engine control unit 17 is activated.
  • the control unit 19 is connected to the battery pack 10 and preferably equipped with a button 21 for a charge status indicator 12.
  • the control unit 19 is used to drive an electric motor 22, on the motor shaft, a pinion 23 is mounted, which is in engagement with a spur gear 24.
  • the spur gear 24 is the output side with a gear 25 into engagement, which is fixed to a wall of a spring housing 26, wherein in the spring housing 26 a not visible in the drawing coil spring is arranged.
  • the coil spring is fixedly connected at its radially outer end to the spring housing 26 and coupled with its radially inner end with the crankshaft of the drive motor 20, in such a way that when relaxing the coil spring, the crankshaft is rotated.
  • the coil spring thus fulfills the function of a spring accumulator.
  • the operating lever 13 is moved to the starting position and held in this a predetermined time, this time may for example be between 0.05 seconds and 3 seconds. In this way, it is determined that an intentional start should occur. Only accidental short-term operation of the operating lever 13 is thus detected as accidental touching.
  • the state of charge of the battery pack 10 can be displayed with the aid of the charge state display 12. This display can also be activated via the button 21 on the control unit 19. If it is detected on actuation of the operating lever 13 in the start position that the internal combustion engine is running (speed detection), no startup process is initiated.
  • the electric motor 22 is connected to the battery pack 10 by the control unit 19.
  • the operating lever 13 is released, whereby it returns to the operating position at position "I" due to the return spring.
  • the power from the battery pack 10 drives the electric motor 22, causing the pinion 23 to rotate, which in turn rotates the gear 25 through the reducing spur gear 24 and the spring housing 26 to which the radially outer end of the coil spring is attached.
  • This rotation of the spring housing 26 causes a tensioning of the Spiral spring until a predetermined spring force is reached.
  • the tensioning of the coil spring rotation of the inner shaft to which the inner end of the coil spring is attached and the crankshaft of the drive motor 20 which can be coupled to this shaft is prevented.
  • the gas lever lock can be provided as a safety measure, which interrupts a contact of the electrical line to the engine control unit 17, so that it is ensured that an unintentional starting operation is avoided by solely pressing the operating lever 13.
  • the throttle valve can be fixed in the starting position, so that when starting the drive motor of the throttle 7 (see. Fig. 1 and 2 ) can not be operated by the user and thus a predetermined amount of fuel is not exceeded.
  • the Fig. 5 shows the operating lever 13 in the motor housing 2, wherein the operating lever 13 in the position "I" includes an electrical switch 29 which is connected via electrical connection lines 33 with an electromechanical actuator 30 and an engine control unit 32.
  • switch 29 When switch 29 is closed, the electromechanical actuator 30 brings the carburetor 28 into the starting position and the engine control unit is activated, as a result of which an injection valve 31 in the carburetor 28 is also actuated. In such a carburetor, no choke flap is needed.
