Patent ID: 8882198

Claim:
An actuating device comprising a handle, a housing, and a driven member, the driven member being rotatable about a longitudinal axis thereof, the housing containing: a brake mechanism, for restricting rotation of the driven member when the brake mechanism is engaged; a means for disengaging the brake mechanism; a means for rotating the driven member in either the clockwise or counter-clockwise direction; and, a clutch mechanism for restricting reverse rotation of the driven member when driven in the clockwise or counter-clockwise direction; wherein the clutch mechanism comprises: a driver drum and a clutch drum, the driver drum and clutch drum being generally coaxially aligned, and wherein the driver drum has a larger radius than the clutch drum; and, a plurality of clutch rotating members positioned between the driver drum and the clutch drum, the clutch rotating members being adapted for frictionally contacting an inner surface of the driver drum and an outer surface of the clutch drum; and wherein the driver drum is provided with a plurality of inward deformations for frictionally engaging the clutch rotating members between the driver drum and he clutch drum; and wherein the brake mechanism comprises: a brake drum and a hub, the brake drum and hub being generally coaxially aligned, and wherein the brake drum has a larger radius than the hub; and, a plurality of brake rotating members positioned between the hub and the brake drum, the brake rotating members being adapted for frictionally contacting an outer surface of the hub and an inner surface of the brake drum; and wherein the brake drum is provided with a plurality of inward deformations for frictionally engaging the brake rotating members between the brake drum and the hub; and wherein: the driven member is operably connected to the brake drum, whereby rotation of the driven member is driven by rotation of the brake drum; the brake drum is operably connected to the clutch drum, whereby rotation of the brake drum is driven by rotation of the clutch drum; and the clutch drum is operably connected to the driver drum, whereby rotation of the clutch drum is driven by rotation of the driver drum.
