Abstract
A rope-operated actuator for an engine starter includes a cover with a shaft, a spool wheel sleeved rotatably on the shaft, a rope connected to the spool wheel for driving the spool wheel, a rope-rewinding member for rewinding the rope on the spool wheel, a pawl-driving member mounted on the shaft, a pair of pawls disposed between the spool wheel and the pawl-driving member and pivotable between engaging and disengaging positions, a wobble-preventing member mounted on the shaft and extending radially and outwardly therefrom, and a retaining member connected to the shaft for retaining the spool wheel, the pawl-driving member and the wobble-preventing member on the shaft.
Claims5
A rope-operated actuator for an engine starter, comprising:
- a cover formed with a central shaft that defines a rotation axis;
- a spool wheel mounted coaxially and rotatably on said central shaft;
- a rope-rewinding member disposed between said cover and said spool wheel;
- a rope connected to said spool wheel and extending outwardly therefrom for driving said spool wheel to rotate about said rotation axis, said rope being rewindable around said spool wheel through said rope-rewinding member;
- a pawl-driving member mounted coaxially and rotatably on said central shaft and having a first side face that faces toward said spool wheel and that is formed with two opposite guiding grooves, and a second side face that is opposite to said first side face;
- an urging member sleeved on said central shaft and abutting against said pawl-driving member for urging said pawl-driving member to move in an axial direction relative to said rotation axis away from said spool wheel;
- a pair of diametrically disposed pawls disposed between said spool wheel and said pawl-driving member, pivoted to said spool wheel, co-rotatable with said spool wheel, and pivotable relative to said spool wheel between engaging and disengaging positions, each of said pawls extending in a radial direction relative to said spool wheel, and being formed with a stud that extends in said axial direction into a respective one of said guiding grooves so as to permit said pawls to be driven by said pawl-driving member to pivot relative to said spool wheel from said disengaging position to said engaging position when said spool wheel is rotated together with said pawls about said rotation axis in a first rotational direction, and from said engaging position to said disengaging position when said spool wheel is rotated together with said pawls about said rotation axis in a second rotational direction opposite to said first rotational direction;
- a wobble-preventing member mounted coaxially on and extending radially and outwardly from said central shaft, and in contact with said second side face of said pawl-driving member;
- and
- a retaining member connected to said central shaft for retaining said spool wheel, said pawl-driving member, and said wobble-preventing member on said central shaft in such a manner to permit said second side face of said pawl-driving member to abut against said wobble-preventing member by virtue of urging action of said urging member and to permit said studs of said pawls to be retained in said guiding grooves in said pawl-driving member.
