Abstract
A door operator including an output shaft, a ball screw, a powered driver, and a yoke. The output shaft is configured to be coupled to a door. The powered driver is operatively coupled to the ball screw and configured to rotate the ball screw in a first rotational direction. The yoke is coupled to the ball screw and configured to translate in response to rotation of the ball screw. The yoke is configured to rotate the output shaft.
Claims19
A door operator, comprising:
- an output shaft configured to be coupled to a door;
- a ball screw;
- a powered driver operatively coupled to the ball screw and configured to rotate the ball screw in a first rotational direction;
- and
- a yoke coupled to the ball screw and configured to translate in response to rotation of the ball screw, the yoke configured to rotate the output shaft,
- wherein the door operator has:
- a first installation configuration in which operation of the powered driver to rotate the ball screw in the first rotational direction causes rotation of the output shaft in a first output shaft rotational direction;
- and
- a second installation configuration in which operation of the powered driver to rotate the ball screw in the first rotational direction causes rotation of the output shaft in a second output shaft rotational direction opposite the first output shaft rotational direction.

3 more elements
A door operator, comprising:
- an output shaft configured to be coupled to a door;
- a ball screw;
- a powered driver operatively coupled to the ball screw and configured to rotate the ball screw in a first rotational direction;
- a yoke coupled to the ball screw and configured to translate in response to rotation of the ball screw, the yoke configured to rotate the output shaft;
- a spring configured to rotate the ball screw in a second rotational direction opposite the first rotational direction;
- and
- a rod extending longitudinally within the spring, wherein the yoke comprises at least one rod recess configured to receive an end of the rod as the yoke is translated.
4 more elements
A method for operating a door operator, comprising:
- rotating a ball screw in a first rotational direction with a powered driver operatively coupled to the ball screw;
- translating a yoke coupled to the ball screw using the rotation of the ball screw;
- and
- rotating an output shaft using the translation of the yoke, the output shaft couplable to a door, wherein the door operator has:
- a first installation configuration in which operation of the powered driver to rotate the ball screw in the first rotational direction causes rotation of the output shaft in a first output shaft rotational direction;
- and
- a second installation configuration in which operation of the powered driver to rotate the ball screw in the first rotational direction causes rotation of the output shaft in a second output shaft rotational direction opposite the first output shaft rotational direction.
