Door and Window System

A door-and-window system, comprising:

• a movable door-and-window subsystem;
• and
• a door-and-window mounting profile;
• wherein the movable door-and-window subsystem comprises a movable door-and-window and a movable door-and-window transmission subsystem, the movable door-and-window transmission subsystem comprising a handle component, a movable door-and-window assembly component, and a transmission component;
• wherein the door-and-window mounting profile comprises a main body, a rail disposed on the main body and configured for the movable door-and-window to move on, and a sealing member mounting portion disposed on the main body and spaced apart from the rail by a predetermined distance;
• wherein the movable door-and-window assembly component comprises a first base seat, a second base seat, a driving member, and a guide member, wherein the first base seat is configured to be assembled with the movable door-and-window and the second base seat is configured to be movably assembled with the rail, or the second base seat is configured to be assembled with the movable door-and-window and the first base seat is configured to be movably assembled with the rail, wherein the first base seat is provided with a first guide groove parallel to the rail, the second base seat is provided with a second guide groove that forms a predetermined first angle with the first guide groove;
• wherein the driving member comprises a force receiving portion movably disposed in the first guide groove, a driving portion movably disposed in the second guide groove, and a driving shaft;
• wherein the force receiving portion and the driving portion are disposed on different sides of the driving shaft;
• wherein the first base seat is provided with a third guide groove that is perpendicular to a plane where the movable door-and-window lies in and that forms a predetermined second angle with the second guide groove, and the guide member is movably disposed in the third guide groove with one end of the guide member fixed to the second base seat, or the second base seat is provided with a third guide groove that is perpendicular to the plane where the movable door-and-window lies in and that forms the second angle with the second guide groove, and the guide member is movably disposed in the third guide groove with one end of the guide member fixed to the first base seat;
• and
• wherein the driving member, the guide member, and the first base seat are set fast relative to the second base seat along a direction perpendicular to a plane determined by the first guide groove and the third guide groove, and the transmission component is assembled with the handle component and the force receiving portion, respectively.
