Window with opening control mechanism

An opening control mechanism for a window having a frame with an interior side and an exterior side, a screen track on the interior side of the frame, and a sash movable between a closed position against the frame and an open position pivoted outwardly from the frame, the opening control mechanism comprising:

• a frame track and release assembly configured to be mounted to the frame or to the sash of the window;
• a sash arm assembly configured to be mounted to the frame of the window if the frame track and release assembly is mounted to the sash or to the sash of the window if the frame track and release assembly is mounted to the frame;
• a sash arm pivotally mounted to the sash arm assembly and extending to a free end;
• the free end of the sash arm being releasably captured by the frame track and release assembly when the sash is opened a predetermined limited amount to prevent further unintended opening of the sash beyond the limited amount;
• and
• a release mechanism including a projection operatively coupled thereto that, when the projection is manipulated in a predetermined manner, releases the free end of the sash arm to allow the sash to be opened beyond its predetermined limited amount, the projection being located on an interior side of the screen track to permit manipulation of the projection without removing an insect screen mounted within the screen track.

A window having an exterior side and an interior side, the window comprising:

• a window frame;
• a sash mounted in the window frame and being attached to the window frame for hinged movement between a closed position against the window frame and an open position hinged outwardly from the window frame;
• a screen track on the interior side of the window frame for receiving an insect screen;
• a frame track and release assembly mounted to the window frame and including a track having an entry end and an exit end and a release mechanism disposed adjacent the exit end of the track;
• a sash arm assembly mounted to the sash generally opposing the frame track and release assembly when the sash is in the closed position, the sash arm assembly comprising an arm pivotally mounted with respect to the sash and having a free end bearing a roller sized to ride along the track of the frame track and release assembly;
• the sash arm having an active position wherein the roller rides along the track of the frame track to the exit end of the track of the frame track and release assembly as the sash is opened and an inactive position wherein the roller is disengaged from the track of the frame track and release assembly;
• the roller engaging the release mechanism upon reaching the exit end of the track of the frame track and release assembly when the sash arm is in the active position to capture the free end of the sash arm and thereby limit the amount that the sash can be opened;
• and
• an activator coupled to the release mechanism for selectively releasing the roller from the track of the frame track and release assembly to permit the sash arm to move to the inactive position allowing the window sash to be opened beyond its limited amount;
• the activator including a projection accessible from the interior side of the screen track to permit manual operation of the activator from the interior side of the screen track.

A window having an exterior side and an interior side, the window comprising:

• a window frame;
• a sash mounted in the window frame and being attached to the window frame for hinged movement between a closed position against the window frame and an open position hinged outwardly from the window frame;
• the window frame being configured to define a screen track for receiving an insect screen;
• an opening control mechanism mounted to the window frame and to the sash for preventing the window frame from being opened beyond a limited amount when the opening and control mechanism is engaged;
• a release assembly for selectively disengaging the opening control mechanism to permit the sash to be opened beyond the limited amount;
• the release assembly including a projection located on the interior side of the window, selective manipulation of the projection disengaging the opening control mechanism without removal of the insect screen when received in the screen track.
