Patents Act 1990 COMPLETE SPECIFICATION STANDARD PATENT ANGLE LIFT WINDOW The following statement is a full description of the invention, including the best method of perfonrming it known to me: The invention relates to another type of window. On page 6, are the isometric drawings of the existing types of windows that can be opened to provide ventilation. Known and in reference with the latest International Standards, the American Institute of Architects, International edition and Nuferts Architect's Data, British International edition which describes these windows as follows: 1. Casement or side hung 2. Sliding or horizontal sliding 3. Double hung or vertical sliding 4. Awning or linked hopper Casement top hung or projected top hung 6. Bottom projected casement or bottom hung 7. Pivoted or vertical pivoted 15 8. Pivoted or-horizoental-pivoted 9. Jalousie or louvers In some cases, more than one type are combined in the design from these basic types of windows.

S To illustrate the invention adapting the devices to the conventional components of the window, reference is made on Fig. 1, up to Fig. 4.

o: Fig. 1, shows the opening movements of the window. Unlike the existing windows, when the lower sash is lifted I, the upper and lower window sashes automatically opens to a horizontal angle outside the window frame.

Fig 2, shows the side view elevation section of the window. A, B C, are the locations of the invention devices installed on the conventional components of the window. The vertical lift of the lower sash with the tilt-lift handle opens a vertical *opening I and automatically opens an angled opening 2, at both sides of the window frame.

2/16 Fig. 3 and Fig. 4, shows the locations of the invention devices at A, B C and identifies the conventional components of the window respectively with the front elevation Fig. 3 and the top view section Fig. 4, of the window, which are as follows: 1. Window head 2. Upper sash 3. Window jamb 4. Lower sash Vertical slide channel of the lift handle 6. Window sill 7. Lift handle 8. Security grilles and/or screen 9. Vertical mullion or window dividers All the suggested window components can either be of extruded aluminium, metal formed steel or stainless steel or any other adaptable metals or materials conforming to the standards for windows. The suggested sizes, configurations, design and assembly, is to illustrate the adaptability of the invention devices to the numerous adaptable and probable preferences of materials, assembly, installation and servicing of the window.

Claims (9)
