Power window operators, windows including the power window operators, and methods of using the same are described herein. The power window operators may offer the ability to control the timing and/or speed of the lock/unlock motion relative to the open/close motions of the operator arm of the power window operator and, if provided, a sash being driven by the power window operator.

A window operator handle and cover with magnetic features that enable the handle to be retained to the cover in a folded position. The operator cover can also be attached to the operator with magnets.

A window operator handle and cover with magnetic features that enable the handle to be retained to the cover in a folded position. The handle can have a detent mechanism to retain the handle in an unfolded position. The operator cover can also be attached to the operator with magnets.

A casement window operator includes a linear input mechanism configured to be mounted to a stationary frame of a casement window, a linear to rotary motion converter operably coupled to an output of the linear input mechanism, a gear reducer operably coupled to an output of the rotary motion converter, and a sash arm operably coupled to an output of the gear reducer to rotate in conjunction with the output of the gear reducer. The sash arm is configured to extend from the stationary frame of the casement window to a rotatable window sash of the casement window.

A building closure operator includes an operator arm pivotable about an arm axis from an arm closed position to an arm open position, an arm lock actuatable to lock the arm in different locked positions and releasable to release the arm, and an articulatable lever pivotable about a lever axis parallel to the arm axis, from a lever home position corresponding to the arm closed position, to a lever actuated position corresponding to the arm open position. The lever includes a lever coupling maintainable in the lever actuated position, and a lever handle pivotable with respect to the lever coupling back to the home position to actuate the arm lock to lock the arm in one of the different locked positions.

A tensioner for a fenestration unit operator includes a base and a guide including a track, the track slidably receiving the base such that the base is restricted to sliding in a first direction with respect to the guide along a sliding axis and a second direction with respect to the guide along the sliding axis that is opposite to the first direction. The tensioner includes a pawl and a ratchet each being a part of one of the sled and the guide, respectively, the pawl being in biased engagement with the ratchet to permit sliding in the first direction and restrict sliding in the second direction, the pawl being configured to be manually disengaged from the ratchet to permit sliding in the second direction. The tensioner includes a pulley coupled to the sled such that the pulley is free to rotate about a rotational axis that is transverse to the sliding axis.
