Problems solved by technology

However, in such an engine starting device, it is not only necessary to pull the coiled rope strongly to increase the pulling speed of the coiled rope to a certain extent, but also the pulled out rope is very long
Therefore, in many cases, elderly and infirm persons cannot easily start the engine

Embodiment Construction

[0114] A preferred embodiment of the engine starting device of the present invention will be described in detail below with reference to the accompanying drawings. In this embodiment, a starting device for an air-cooled small internal combustion engine applied to a chain saw is exemplified. However, the same type of engine starting device can be applied to lawn mowers, rotary saws, and the like.

[0115] Fig. 1 is a sectional view of an embodiment of the internal structure of a small engine equipped with the engine starting device of the present invention. FIG. 2 is an exploded perspective view of components installed inside a cover box of such an engine starting device. Fig. 4 is an internal structural view showing a disengaged state of the mode switching device in the starter device. Fig. 5 is an internal structural view showing the engaged state of the start timing selection means.

[0116] As shown in Figures 1 and 2, the small engine 100 of this embodiment is equipped ...

Abstract

An engine start device having a first start mode in which an engine is started by engine start operation to immediately start the engine and also having a second start mode in which force required for shock-absorbing / force-storage means is stored in advance and the engine is started in the first attempt at desired time and place. In the first start mode, force stored in the shock-absorbing / force-storage means (9, 10) by rotation of a rotation / drive section (D) is directly transmitted to a rotation / driven section (M) and the engine is immediately started. When the first start mode is switched to the second start mode, the rotation of the rotation / drive section (D) is stored entirely in the shock absorbing / force storage means (9, 10), the force stored in the shock absorbing / force storage means (9, 10) is released at desired time and place, thereby rotating the rotation / driven section (M) to start the engine through one-touch operation. The device has first and second engagement members (14, 15) and single switchover operation means (16). The first and second engagement members (14, 15) are engaged to and disengaged from the shock-absorbing / force-storage means (9, 10) and the rotation / driven section (M), respectively, to block and allow reverse rotation of the shock-absorbing / force-storage means (9, 10) and that of the rotation / driven section (M), respectively. The switchover operation means (16) causes engagement and disengagement of the shock absorbing / force storage means (9, 10) and the rotation / driven section (M) in cooperation with the first and second engagement members (14, 15).

Description

technical field [0001] The present invention relates to a starting device for an internal combustion engine, and more particularly to a starting device for a small engine, which can smoothly start the engine in accordance with the operation of pulling a winding rope by using a damping / energy storage device such as an energy storage spring , wherein the engine starting device enables the engine to be started safely and reliably at an optional time and place without pulling the wound rope where it is inconvenient to pull the wound rope, and can prevent the engine from being accidentally started. Background technique [0002] A manual starting device for an internal combustion engine typically starts the engine by pulling a coiled rope to turn a rope reel and transmitting the rotation of the rope reel to the crankshaft of the engine. However, in such an engine starting device, not only the winding rope needs to be pulled strongly to increase the pulling speed of the winding rop...
