Abstract
On-axis actuator system includes an actuator bracket formed with at least one bracket cavity. Actuator links couple open and close rollers. An actuator member coupled to close roller and disposed within an actuator housing. Moving the actuator member towards the actuator bracket presses the close roller against the bracket to rotate the bracket. A device coupled to the bracket rotates with the bracket.
Claims14
An actuator system comprising:
- an actuator bracket formed with at least one bracket cavity;
- at least one first roller;
- at least one second roller disposed within the at least one bracket cavity;
- first and second actuator links, wherein a first end of each link of the first and second actuator links is coupled to the at least one first roller and a second end of each link of the first and second actuator links is coupled to the at least one second roller;
- an actuator member having a first end and a second end, wherein the actuator member is coupled to the at least one first roller at the first end of the actuator member;
- and
- an actuator housing formed with a central cavity comprising a first chamber and a second chamber and formed with an aperture connecting the central cavity and exterior of the actuator housing;
- wherein the actuator member is partially disposed within the actuator housing such that the actuator member extends past the actuator housing through the aperture.
