Abstract
A swing door operator having a powered driver operable to manipulate a drive unit that rotates a spindle to open a door. As the door is opened, the drive unit compresses a spring engaged with a spring mount that is pivotally connected to the drive unit. The spring mount is pivotable between an operating configuration in which the spring is arranged to be compressed by the drive unit as spindle rotates in the first direction and to expand thereafter to rotate the spindle in a second direction opposite the first direction, and a servicing configuration in which the spring is slidably removable from the spring mount.
Claims24
A swing door operator, comprising:
- a spindle;
- a drive unit operatively coupled to the spindle;
- a powered driver operatively coupled to the drive unit and operable to move the drive unit to rotate the spindle in a first direction;
- a spring;
- and
- a spring mount engagable with a first end of the spring and pivotally connected to the drive unit, the spring mount being pivotable between:
- an operating configuration in which the spring is arranged to be compressed by the drive unit as spindle rotates in the first direction and to expand thereafter to rotate the spindle in a second direction opposite the first direction;
- and
- a servicing configuration in which the spring is slidably removable from the spring mount.
A system, comprising:
- a door;
- and
- s swing door operator, comprising:
- a spindle;
- a drive unit operatively coupled to the spindle;
- a powered driver operatively coupled to the drive unit and operable to move the drive unit to rotate the spindle in a first direction;
- a spring;
- and
- a spring mount engaged with a first end of the spring and being pivotally connected to the drive unit, the spring mount being pivotable between:
- an operating configuration in which the spring is arranged to be compressed by the drive unit as spindle rotates in the first direction and to expand thereafter to rotate the spindle in a second direction opposite the first direction;
- and
- a servicing configuration in which the spring is slidably removable from the spring mount.
A method for replacing a spring in a swing door operator, comprising:
- releasing a first end of a first spring;
- pivoting the first end about a spring mount supporting a second end of the first spring;
- and
- sliding the first spring away from the spring mount in a direction extending from the second end toward the first end.
A swing door operator, comprising:
- a housing comprising a top, a bottom, an outward facing side and an inward facing side, the inward facing side being configured to face a wall or door structure when installed for use, the outward facing side configured to face away from the wall or door structure when installed for use, the housing having a longitudinal axis;
- a drive unit in the housing and at least partially disposed adjacent the inward facing side of the housing;
- a powered driver carried by the housing and operatively coupled to the drive unit and operable to move the drive unit to rotate the spindle in a first direction;
- a spring offset from a central portion of the housing and disposed adjacent the outer facing side when the housing is installed for use;
- and
- a spring mount supporting the spring and displaceable relative to the housing to move the spring between an operating position substantially parallel to the longitudinal axis of the housing and a servicing configuration in which the spring is angled relative to the longitudinal axis of the housing.
