Abstract:
1. A wind-up device for use with a dispenser comprising: a) a body, a gripper inserted into the body, and a brake disposed between the body and the gripper for controlling the direction of rotation of the gripper relative to the body; b) the brake further comprises a plurality of fingers for engaging a plurality of body notches on one of the body or the gripper; c) wherein rotation of the gripper relative to the body causes the fingers to engage and disengage with the body notches at spaced-apart intervals; d) wherein the brake further comprises an inner diameter and an outer diameter and a plurality of alignment notches formed along the inner diameter, the plurality of fingers having cam surfaces and end surfaces extending from the cam surfaces toward the inner diameter, and wherein the plurality of fingers are biased outwardly relative to the outer diameter and are deflectable downwardly into a tangential relationship with the outer diameter in response to a force applied to the cam surfaces, the plurality of fingers being deflectable into elongated openings defined between the inner and outer diameters; and e) wherein the plurality of alignment notches are angularly displaced relative to the plurality of fingers, the plurality of fingers are arranged at ninety degree intervals around the outer diameter, and the plurality of alignment notches are arranged at ninety degree intervals around the inner diameter.
