Fig. 4 is embodiment two folded state schematic diagrames, and Fig. 5 is embodiment two open configuration schematic diagrames.

With reference to Fig. 1, Fig. 2, the door and window locator that is embodiment one comprises: on 1) folded mutually and isometric, lower beam 1,2, on, lower beam crosses at a side of cross bar 3 at the bottom of the door and window and parallels with it, on, the rear end of lower beam is hinged, 2) be fixed in the undersetting 5 of the end cross bar 4 of door window frame, the front end of undersetting and lower beam is hinged, 3) be fixed in the upper bracket 6 that is positioned at the undersetting top of cross bar at the bottom of the door and window, the front end of upper bracket and upper boom is hinged, 4) hinge axis 7 of above-mentioned each hinged place parallels (on guaranteeing with the rotating shaft of door and window, lower beam rotates on horizontal plane), 5) on, the length L of lower beam should equal for a short time

S, S are the distance of bearing pin joint to the Pivot for door or window axes extending line.

Purpose for the qualification of the length L of upper and lower bar: the one, can guarantee the installation of door and window locator, the 2nd, can guarantee door and window when opening (corner is in 90 ° of scopes), upper and lower bar is upheld in line.

Using method of the present utility model is: when windowing, push window open and cause upper and lower bar to be upheld in line, get final product, (as Fig. 3) when closing window, one draws door and window inward, just this door and window locator is shut the back and is folded into one (as Fig. 1) along with door and window.
