Abstract:
1. A positive locking roller stop device comprising: a first disk mounted on a shaft, wherein the first disk rotates relative to the shaft via a bearing; a second disk fixed to the shaft in a position parallel to the first disk; one or more spring arm rollers including an arm pivotally coupled to one of the first disk and the second disk and a roller attached to the arm, wherein the arm is biased axially towards the other of the first disk and the second disk so that the roller contacts one of an inclined ramp or an inclined notch integrated with the other of the first disk and the second disk, wherein in a first direction the roller permits freewheeling rotation of the first disk and second disk relative to the other and in a second direction the roller positively engages a portion of the inclined ramp or the inclined notch to transmit rotational energy and prohibit rotational motion of the first disk relative to the second disk.
