Patent ID: 8661932

Claim:
A speed control device operable between a cable-winding operation mode and a cable-releasing operation mode, comprising: a control assembly including a fixing member, a first engaging mechanism pivotally connected to the fixing member, and a second engaging mechanism pivotally connected to the fixing member; wherein the fixing member includes a body, a first pawl device selectively engaged with the first engaging mechanism, and a second pawl device selectively engaged with the first engaging mechanism, with the fixing member having a first connected portion where the first pawl device is disposed to, and a second connected portion where the second pawl device is disposed to; wherein the first engaging mechanism includes a cable-receiving member rotatable in a first rotation direction to up-shift a speed and a second rotation direction to down-shift the speed; wherein the second engaging mechanism includes a control plate, an engagement plate, and a clutching device, with the control plate having an arm portion, with the clutching device disposed to the arm portion of the control plate and selectively engaged with the first engaging mechanism, wherein the engagement plate includes a first protrusion and a second protrusion, which protrude from an outer periphery thereof, wherein the first and second protrusions correspond to the first pawl device and the second pawl device, respectively; and wherein the control assembly is adapted to effect a multiple speed change in one stroke of the second engaging mechanism, wherein the first pawl device includes a first engaging section and a first abutted section abutted by the first protrusion, wherein the second pawl device includes a second engaging section and a second abutted section abutted by the second protrusion, wherein the first engaging mechanism includes a first toothed section selectively engaged by the first engaging section, and a second toothed section selectively engaged by the second engaging section, wherein when the second engaging mechanism is not operated, the first engaging section is disengaged from the first toothed section, and the second engaging section is engaged with the second toothed section, wherein the engagement plate includes a hole extending therethrough, wherein the body includes a holding surface, wherein the holding surface and a center of the hole has a distance therebetween smaller than that of the first protrusion and the center of the hole, wherein the second engaging mechanism includes a catching member including a second emboss, wherein the engagement plate includes an abutted surface corresponding to the second emboss of the catching member, wherein as the catching member rotates in the second rotation direction, the engagement plate is rotated in the second rotation direction as the abutted surface is abutted by the second emboss of the catching member, and the first abutted section is disengaged from the first protrusion to engage the holding surface of the body.
