A window operator assembly comprises a leadscrew and an elongated nut. The leadscrew is pivotally connected to a window frame via a frame pivot and is rotatable relative to the window frame. The elongated nut is pivotally connected to a window sash via a sash pivot. As the leadscrew rotates in a first direction, the elongated nut moves in a first direction along the leadscrew and moves the window sash toward an open position relative to the window frame. As the leadscrew rotates in a second direction, the elongated nut moves in a second direction along the leadscrew and moves the window sash toward a closed position relative to the window frame.

Window operator

A window operating system moves a window sash between an open position and a closed position. A window has a top member operatively connected to a bottom member by a first side member and a second side member to form a frame. The sash is mounted to the frame for relative movement between the open and closed positions. The window operating system comprises an operator and an elongate member. The operator has a rotating member, and the elongate member provides rotational movement to the rotating member of the operator and movement of the elongate member rotates the rotating member thereby opening and closing the sash.

Window operating system

A window operator moves a sash between an open and closed position. The window operator includes a track member and a sliding member. A gear member has a second end adapted and configured to be operatively connected to the window sash and a first end has a plurality of radially spaced gear members. A rack member is positioned proximate the track and is positioned to engage the gear teeth. One of the gear members and rack member is operatively connected to the sliding member. The other is positioned proximate the track and has no longitudinal movement relative to the track. A drive member is connected to the sliding member, wherein actuation of the drive member moves the sliding member longitudinally and causes the gear teeth to engage the track, thereby resulting in rotational movement of a gear member to move the sash between an open and closed position.

Rack gear operator

A lead screw window operator () utilizes a lead screw () that is in tension whether the operator is being used to open or close a window assembly (). The lead screw window operator () may include a nut () that has edges sufficiently close to first and second support surfaces to prevent excess rotation of the nut (). Also, the lead screw () may have a splined end to operatively connect to a first gear that has a splined profile to allow the gear to slide along the lead screw along a longitudinal axis.
