Abstract

An engine starting device for an internal combustion engine, includes an energy storing mechanism including at least one elastic member, an input element engageable with the elastic member and movable into contact with a rotatable engine member of an engine to load the elastic member, an output element that is movable in response to unloading of the elastic member, at least one manual actuator to enable unloading of the elastic member, a locking mechanism engageable with the energy storing mechanism to prevent the elastic member from unloading from a loaded state, a sliding member, a cam member mounted to the sliding member, a pivot link pivotably mounted to the sliding member, and a key device coupled to the pivot link. In operation, rotation of the key device in a locking direction causes the pivot link to move the sliding member, thereby causing the cam member to engage the locking mechanism when the locking mechanism is positioned in engagement with the energy storing mechanism. The key thus locks the locking member to resist disengagement of the locking mechanism from the energy storing mechanism.
