Casement and awning window opening limit device

A window assembly, comprising:

• a window frame;
• a sash receivable in the window frame, the sash selectively shiftable through a first travel distance between a closed position in which the sash is received in the window frame and a fully open position in which the sash is hinged away from the window frame;
• and
• a sash opening limit device comprising:
• a sash bracket attached to the sash;
• a limiting arm operably coupled to the sash bracket, the limiting arm presenting a proximal end and a distal end, the proximal end of the limiting arm pivotally coupled to the sash bracket, the limiting arm further including a track engagement structure proximate the distal end;
• and
• a track assembly adapted to attach to the window frame, the track assembly including a track and a release assembly, the track presenting a first end and an opposing second end and having a first opening which allows the track engagement structure proximate the first end to enter the track and a second opening which allows the track engagement structure to exit from the track proximate the second end, the track engagement structure of the limiting arm being slidable in the track, the release assembly disposed proximate the second end of the track and selectively operable to release the track engagement structure from engagement with the track through the second opening in the track, wherein the track engagement structure is engaged in the track when the sash is in the closed position, and as the sash is shifted toward the open position, the track engagement structure slides in the track toward the release assembly, the release assembly preventing the track engagement structure from disengaging from the track until the release assembly is operated, the limiting arm acting to limit further movement of the sash to a second travel distance less than the first travel distance until the track engagement structure is disengaged from the track, and wherein a biasing structure is operably coupled to the sash bracket and the limiting arm, the biasing structure biasing the limiting arm toward an engagement position in which the distal end of the limiting arm is spaced apart from the sash.
