The present invention relates to a device for hanging windows, doors and the like that include a frame (100) and a casement sash (200) or the like that can be reversibly rotated about a generally vertical axis. The device includes an upper guide (1) and a lower guide (8) which can be fixed to the upper and lower frame members respectively, and an upper slide (2) and a lower slide (9) which can be fixed to the frame for rotation about the generally vertical axis and an upper pivotal arm (5) and a lower pivotal arm (11) which can be fixed rotatably to the upper and the lower frame members and to the casement sash respectively. With the intention of producing an improved window or door hanging device that facilitates storage, distribution, and fitting of the device, the lower pivotal arm is pivotally fixed to the lower guide. |
