Abstract
Motorized actuators for pivoting fenestration units that include both lock and open/close actuation, are addressed. Such actuators, and associated fenestration systems and methods, may achieve a variety of potential advantages, including egress functionality, ease of operation, active position control, aesthetically pleasing features (e.g., minimal design impact), intuitive controls, and others.
Claims18
A powered operator system for a fenestration unit, the powered operator system comprising:
- an operator motor assembly having an output pulley oriented in a first direction;
- an operator assembly having an input pulley oriented in a second direction that is substantially perpendicular to the first direction;
- and
- a drive belt forming a continuous loop extending between the output pulley and the input pulley to operably couple the operator motor assembly to the operator assembly, the drive belt defining a twisted configuration between the output pulley and the input pulley.
A powered operator system for a fenestration unit, the powered operator system comprising:
- an operator motor having an output pulley oriented in a first direction and an output pulley coupled to the output pulley;
- an operator assembly having an input pulley oriented in a second direction that is substantially perpendicular to the first direction and an input pulley coupled to the input pulley;
- a drive belt extending between the output pulley and the input pulley to operably couple the operator motor to the operator assembly;
- an output belt guide associated with the output pulley, the output belt guide including a first output guide member, a second output guide member, and an arcuate output guide surface surrounding at least a portion of the drive belt to substantially inhibit belt slippage on the output pulley;
- and
- an input belt guide associated with the input pulley, the input belt guide including a first input guide member, a second input guide member, and an arcuate input guide surface surrounding at least a portion of the drive belt to substantially inhibit slippage of the drive belt on the input pulley;
- wherein the output belt guide includes an output guide frame portion that is configured to be mounted with the output pulley within the output guide frame portion and the output pulley being rotatable within the output belt guide.
A powered operator system for a fenestration unit, the powered operator system comprising:
- an operator motor having an output pulley oriented in a first direction and an output pulley coupled to the output pulley;
- an operator assembly having an input pulley oriented in a second direction that is substantially perpendicular to the first direction and an input pulley coupled to the input pulley;
- a drive belt extending between the output pulley and the input pulley to operably couple the operator motor to the operator assembly;
- an output belt guide associated with the output pulley, the output belt guide including a first output guide member, a second output guide member, and an arcuate output guide surface surrounding at least a portion of the drive belt to substantially inhibit belt slippage on the output pulley;
- and
- an input belt guide associated with the input pulley, the input belt guide including a first input guide member, a second input guide member, and an arcuate input guide surface surrounding at least a portion of the drive belt to substantially inhibit slippage of the drive belt on the input pulley;
- wherein the drive belt is formed of a flexible material that forms a continuous loop.
