Abstract

A gasoline grass trimmer includes an internal combustion engine (ICE) (15), a starter system (1) configured to start the engine (15).
The present invention relates to an engine starter system (1) that can transmit external rotating force or using internal Pulling Wheel System (4, 8) generated rotational force through the 'Dual Force Clutch' (7), 'Buffering Spring' (9) and drive the 'Driving Plate' (2) to start the (ICE) (15). The present invention states that external rotational force from electrical power driven device (5.1 and 5.2), such as power tool, can be applied through the 'External Rotating Force Connector' (5) to start up the ICE. Or if such electrical power driven device electrical rotating device is not available, the ICE can also be started by the built-in Pulling Wheel System (4, 8) of this Dual Source Starter System.

Description

    THE TECHNOLOGY SCOPE
  • The present invention relates to internal combustion engine (ICE), outdoor power equipment powered by such engines, such as grass trimmer, lawn mower, hedge trimmer, chain saw, cut off saw, generator, high pressure cleaner, pump, etc. more specifically, the present invention relates to a starter system. That can start up the internal combustion engine (ICE) by either internal or external rotational force.
  • The present invention relates to start system for internal combustion engine (ICE), using either internal rotational force generated by built-in 'Pulling Wheel System' (4, 8) or applying external rotational force through the 'External Rotational Force Connector' (5).
    • TECHNOLOGY BACKGROUND
  • The Dual Source Starter System includes an 'External rotational Force Connector' (5) and 'Dual Force Clutch' (7) system (7, 7.1, 7.2, 7.3) that transmits external rotational force to start up the internal combustion engine independently. Furthermore, the 'Dual Force Clutch' (7) system (7, 7.1, 7.2, 7.3), can also start up the ICE independently by using the built-in 'Pulling Wheel System' (4, 8).
  • The rotational force drives through the 'Dual Force Clutch' (7) system (7, 7.1, 7.2, 7.3), to the 'Buffering Spring' (9) and then to the 'Driving Plate' (2) to start up the ICE.
  • The incorporation of 'External Rotational Force Connector' (5) allows an option for extra Independent ICE start up power source input. When force is applied to 'External Rotational Force Connector' (5), the 'Dual Force Clutch' (7) system (7, 7.1, 7.2, 7.3) automatically disconnects with 'Pulling Wheel System' (4, 8) to allow the ICE to start up by the external rotational force.
    • Invention Summary
  • The purpose of present invention is, an improved ICE start up system enhancing ICE start up procedure by using external rotational force
  • According to existing starters for ICE which requires continuous manual pulling action to 'Pulley Wheel' (4) until the ICE starts up
  • According to present invention, the 'Dual Force Clutch' (7) system (7, 7.1, 7.2, 7.3) is structured to allow using either internal or external force application to start up ICE and automatically idle the other source of force. Therefore, eliminate the need for a manual mode selector.
  • The 'Dual Force Clutch' (7) has been integrated with the 'External Rotational Force Connector' (5) transmits external rotational force to 'Buffering Spring' (9), which connected to 'Driving Plate' (2) and 'Clutch Spindle', this structure has high efficiency in mechanical force transmission and much lower production cost.
  • The Dual Force Clutch is also connected with the pulley wheel (4), when pulling force is applied, rotational force generated transmits through the 'Dual Force Clutch' (7), to the 'Buffering Spring' (9), to the 'Driving Plate' (2) and to the clutch spindle to start up the ICE.
