Claims
- 1. An engine starting device comprising:
- an input member mechanically and operably connected to an engine;
- a spiral spring;
- an output member mechanically and operably connected to said spiral spring;
- a driving member operably connected to and driven by said engine;
- automatic force accumulating means operably connected to said spiral spring for accumulating force in said spiral spring;
- said driving member being operably connected to said automatic force accumulating means for driving said automatic force accumulating means;
- a winding pressure accumulating mechanism operably connected to said spiral spring;
- a first one-way clutch means for selectively connecting said automatic force accumulating means with said winding pressure accumulating mechanism;
- means for connecting said output member to said input member when the force accumulated by said spiral spring is released to start said engine;
- a cam provided on an output shaft which is also an input member at the time of starting the engine;
- said automatic force accumulating operation means comprising an intermittently rotating member rocked by said cam; and
- said intermittently rotating member and spiral spring winding pressure accumulating mechanism being connected with each other through a one-way clutch.
- 2. A device according to claim 1, wherein:
- a cam is provided on a half body of a one-way clutch secured to the engine crankshaft, and is disposed between the spiral spring force accumulation releasing output member and the crankshaft.
- 3. A device acording to claim 1, including:
- an automatic spiral spring force accumulating operation mechanism rocked by a cam provided on said crankshaft of the engine to intermittently rotate;
- an artificial force accumulating operation mechanism rotated intermittently by an artificial operation to wind said spiral spring to accumulate a force;
- a spiral spring winding pressure accumulating mechanism; and
- said winding pressure accumulating mechanism and each of said force accumulating operation mechanisms being connected with each other through a one-way clutch.
- 4. A device according to claim 1 wherein:
- a one-way clutch (23) is formed of the output member of said spiral spring (31) and the input member provided on the engine crankshaft (22);
- a driven sprocket (34) winding said spiral spring (31) to accumulate a force is provided on said spiral spring (31) to be driven by a driving sprocket (201) loosely fitted on an operating shaft (60) intermittently rotated and driven by an artificial operation;
- an intermittently rotating member (220) is loosely fitted on said operating shaft (60);
- a one-way clutch (222-23) is provided between said intermittently rotating member (220) and said operating shaft (60);
- an input member (310) rocked by a cam (302) provided on a half body (300) of a one-way clutch (23) of the engine crankshaft (22) is loosely fitted on said intermittently rotating member (220) through a one-way clutch; and
- said driving sprocket (201) and intermittently rotating member are connected with each other through a planetary gear mechanism (202-206).
- 5. A device according to claim 4, including:
- a mechanism disengaging said input member from said cam (302) in the position of the end of winding said spiral spring (31).
