Abstract
An engine start device having a first start mode in which the engine is started on a spot by executing a start operation of the engine, and a second start mode in which a necessary accumulated force is previously accumulated in to start in one time in an optional place at an optional timing. In the first start mode, an accumulated force, accumulated by a rotation of a rotation drive section allows the engine to be started on the spot. If switched to the second start mode, the rotation of the rotation drive section is exclusively accumulated and released in the optional place at a desired time so as to start the engine in accordance with a one-touch operation.
Claims6
An engine start device comprising:
- a rotation drive section;
- a rotation driven section to which a rotation of the rotation drive section is transmitted;
- and
- a damping and accumulating device interposed between the rotation drive section and the rotation driven section, and accumulating a force while damping on the basis of a driving of the rotation drive section in a process of the driving the rotation drive section, and starting up an engine via the rotation driven section on the basis of the accumulated force,
- wherein the damping and accumulating device comprises a mode switching device switching a mode from a first start mode in which the rotation of the rotation drive section is directly transmitted to the rotation driven section via the damping and accumulating device, to a second start mode in which the rotation of the rotation drive section exclusively accumulates the force in the damping and accumulating device and releases the accumulated force accumulated in the damping and accumulating device at a desired time so as to rotate the rotation driven section, and
- the mode switching device comprises:
- first and second engaging and disengaging members which engage with and disengage from each of the damping and accumulating device and the rotation driven section so as to respectively inhibit and allow a reverse rotation of the damping and accumulating device and the rotation driven section, and
- a single switch operating device which is configured to operate the first and second engaging and disengaging members together in mechanical cooperation such that the first and second engaging and disengaging members may be engaged with and disengaged from the damping and accumulating device and the rotation driven section, respectively, wherein said engagement and said disengagement respectively inhibit and allow a reverse rotation of the damping and accumulating device and the rotation driven section, and further wherein:
- the first engaging and disengaging member is pivoted to a cover case of the start device, and integrally has an engaging portion which is urged toward an engaging and disengaging portion disposed around the damping and accumulating device, and an operating portion in cooperation with the second engaging and disengaging member so as to rotate the engaging portion in an engaging and disengaging direction, and
- the second engaging and disengaging member is pivoted to the cover case, and integrally has an engaging pawl portion which is urged in a locking direction of the rotation driven section, and an operating portion connected to the operating device so as to engage and disengage the engaging pawl portion with and from the rotation driven section.
