Patents Act 1990 COMPLETE SPECIFICATION FOR A STANDARD PATENT C Ca C IC C CC CCrC Name of Applicants: Actual Inventors: Address for Service: Invention Title: Details of Associated 24 September 1991 GEORGE STUART WOODSTOCK KIBBLE ANTHONY EDWARD HERRELL GEORGE STUART WOODSTOCK KIBBLE ANTHONY EDWARD HERRELL CULLEN CO., Patent Trade Mark Attorneys, 240 Queen Street, Brisbane, Qld. 4000, Australia.
A COMBINATION DOOR AND WINDOW Provisional Applications: No. PK8533 filed f The following statement is a full description of this invention, including the best method of performing it known to us: i 1-i I *i 2 THIS INVENTION relates to a combination door and window assembly. In particular, the invention is directed to a sliding glass door incorporating at least one sliding window. The invention also relates to an adaptor frame for converting a conventional sliding glass door to incorporate a window.
Sliding glass doors are popular constructional features of residential and commercial buildings, such as motels. A sliding door assembly typically comprises a door frame fixed to a wall of a building around an aperture, and two door members or portions mounted in the frame. One door portion is typically fixed in position, and the other is slidable within the frame, parallel to the fixed door portion.
The two portions are normally closely spaced to allow sealing to be effected between the two portions when the sliding door portion is closed. Each portion normally comprises a rectangular metal frame, typically of aluminium, having a glass panel fitted therein. In some sliding doors, the glass within each portion is divided into upper and lower sections by a metal crossbeam or transom.
Sliding glass doors are relatively simple and economic to manufacture and install. Further, since most of the wall aperture is occupied by glass, the sliding door allows light to enter the room and thereby create a light and airy atmosphere.
i However, conventional glass sliding doors have the inherent disadvantage of not permitting any ventilation when the door is closed. Although the door can be opened to allow ventilation, the open door no longer provides any security.
For example, an opened door will no longer restrain small children, and, in the absence of constant adult supervision, the children may wander outside into potentially dangerous situations. If the sliding door opens onto an area containing a pool, legislation may require that the door be self-closing or otherwise kept closed, thereby preventing any ventilation.
Even if the door is opened, the maximum open area which can be achieved for ventilation is 50% of the total aperture in the building.
Australian patent no. 542395 discloses a door having 3 a sliding panel and a security grille. By opening the panel but keeping the door closed, ventilation can be obtained without compromising security.
Australian patent no. 514896 describes a door assembly comprising a main door having a wicket door to permit ventilation while the main door is closed.
However, the known doors with windows are hinged wooden doors, i.e. doors which pivot about a vertical axis.
Hitherto, the close spacing of the relatively movable portions of sliding doors has precluded the use of windows in sliding glass doors. That is, if a window were to be inserted in the fixed and/or sliding portion of a sliding door, the window assembly itself, or the opening of the window, would interfere with the sliding movement of the movable portion.
Further, the glass construction of the doors did not readily permit the installation of window assemblies in the door portions or members.
It is an object of the present invention to provide o0: a sliding door having at least one window.
It is another object of the present invention to oO- provide an adaptor frame to enable at least one window to be .0o° retrofitted to a conventional sliding door.
In one broad form, the present invention provides a 0 sliding door assembly comprising at least one slidable glass door member, characterised in that the door member has a r sliding window assembly mounted therein.
Typically, the door assembly comprises two glass S door members, one of which is slidable, and the other may be fixed or slidable. Preferably, at least one sliding window 0c assembly is mounted in each door member.
Conventional glass sliding doors may be converted to the sliding door/window assembly of this invention. Each door member of a conventional sliding door normally comprises a frame adapted to hold a glass panel. Typically, the glass i panel is received within a channel defined in the frame and I located generally in the central plane of the frame. In the preferred embodiment of this invention, an adaptor frame is panel. The~ ~a adaptor frame ha rjcinetning fitted to the frame of a door member in place of the glass panel. The adaptor frame has a projection extending

a I Ca 4 t 4 t a 2P SI U Ut 4 into the channel of the frame of the door member. A sliding window assembly is then fitted to the adaptor frame.
The projection on the adaptor frame is offset from the central plane of the adaptor frame so that when the window assembly is fitted to the adaptor frame, the central plane of the window assembly will be offset relative to the central plane of the door frame. The window assembly fitted to a door member is offset on the opposite side of the door member to the other door member, thereby enabling the two door members to continue sliding past each other in close relationship.
Each sliding window assembly may be of conventional design comprising two window members mounted in a frame, at least one window member being slidable. Each window assembly may also comprise a security screen and/or insect screen.
Typically, the area within the frame of each door member is substantially fully occupied by one or more window assemblies. The door members are approximately of equal size, and the window members within each window assembly are approximately of equal size.
In order that the invention may be more fully understood and put into practice, a preferred embodiment thereof will not be described with reference to the accompanying drawings, in which: Fig. 1 is an elevation of a sliding door incorporating windows, according to one embodiment of this invention, Fig. 2 is an exploded partial perspective view illustrating the frame construction of the door of Fig. i, Fig. 3 is a sectional view of the window jamb and adaptor frame, Fig. 4 is a sectional view of the window head and adaptor frame, and Fig. 5 is a sectional view of the window sill and adaptor frame.
Referring to Fig. 1, the sliding door 10 of the illustrated embodiment comprises a rectangular frame 11 fixed to the wall defining the aperture for the door 10. The door frame 11 comprises opposed jamb members, a head and sill. A door member or portion 12 is fixedly mounted in one half of
I
I
I
i the door frame 11, and a movable door member or portion 13 is slidable within tracks defined by the head and sill of door frame 11. The movable portion 13 slides parallel to fixed portion 12 in close relationship thereto. When the movable portion 13 is closed, a seal closes the space between the two door portions 12, 13. To ensure good sealing, the two portions 12, 13 are normally mounted close together with sufficient clearance only to permit relative sliding movement.
In a conventional sliding door, each portion 12, 13 typically comprises a rectangular metal frame within which a sheet of glass is mounted. The frame is provided with a channel around its inside, within which the edges of the glass panel are received and held. The illustrated embodiment will S be described with reference to its construction by modification or retrofitting of a conventional sliding door.
*0 In the illustrated embodiment, each portion 12, 13 is divided into two by a transom 14. However, it will be apparent to those skilled in the art that the provision of a transom 14 is purely optional.
Each of the four segments of the sliding door contains a sliding window assembly comprising a rectangular frame 18 having a fixed portion 15 and a sliding portion 16.
The sliding portion 16 slides parallel to the fixed portion U 15. A security screen 17 is suitably provided on each window 2' frame, on the outside of the sliding window portion 16. The security screen 17 may have insect mesh on the inside thereof for screening purposes.
4 *4 Figs. 2-5 illustrate the retrofitting of the window assemblies to a sliding door. To install the window assemblies, each portion 12, 13 of the door is removed from the frame 11, the head section of the frame of each portion and the transom 14 are removed, and the glass is removed from the frame of each portion. An adaptor frame 20 is then fitted to the peripheral frame of each door portion 12, 13. In the specific embodiment illustrated in Fig. 1, two adaptor frames I will be fitted to each door portion, separated by transom 14.
The adaptor frame 20 is of channel section consisting of a central web portion having flanges along its edges defining the sides of the channel. Two parallel spaced 6 flanges having barb-like edges extend longitudinally along the channel section 20 on the side of the web portion opposite the side walls, as shown more clearly in Fig. 3. The fitting 21 formed by these flanges is designed to be inserted into the channel in the frame of the door portion in which the glass panel was previously inserted. Thus, as illustrated in Fig.
2, the fitting 21 on the jamb of adaptor frame 20 is snapfitted into the channel in the jamb of the frame of door portion 12 to thereby mount a vertical section of the adaptor frame 20 to the existing frame of door portion 12. (For clarity, only a portion of the lerlgth of the adaptor frame is illustrated in Fig. A similar procedure is used for the other jamb, the head and sill of the adaptor frame.
Sit The frame 18 of a window assembly is received within 164 the side walls of the channel section of adaptor frame Sealing members 22 are located in longitudinal channels 23 along the inside of the side walls of the adaptor frame 20, to S'1 seal the space between the window frame 18 and adaptor frame The window frame 18 and each window assembly are generally of conventional construction and therefore are not described or illustrated in detail in this application.
To minimise costs, the glass panels removed from the existing door portions may be cut to size and used in the window assemblies.
In a typical retrofitting procedure, the bottom or sill section of the adaptor frame 20 is first fitted to the Cs bottom or sill section of the frame of a door portion by snapfitting portion 21 into the channel in which the glass sheet was previously inserted. The side or jamb sections of the adaptor frame 20 are then fitted in a similar manner to the opposed side or jamb sections of the frame of the door portion. A window assembly 18 is then slidably inserted between the opposed side sections of the adaptor frame 20 to sit withini the bottom section of the adaptor frame. The head or top transverse section of the adaptor frame 20 is then placed over the corresponding section of the window frame 18 (as shown in Fig. and the transom 14 is snap-fitted onto the upstanding portion 21, to thereby complete the 4.
'rr ra i:' ~;nli installation of a sliding window assembly in the lower half of a door portion.
The above procedure is repeated for the window assembly in the upper half of the door portion. The head of the frame of the door portion, which was previously removed to enable the adaptor frame and the window assemblies to be fitted, is snap-fitted onto the top transverse section of the adaptor frame to complete the installation of the window assembly in the upper half.
The overall thickness of the window assembly is significantly greater than the thickness of the original glass panel. If the window assemblies were mounted centrally relative to the plane of each door portion, the window assemblies would interfere with the opening of the door. To overcome this problem, the fitting 21 is located off centre S relative to the central plane of adaptor frame 20, as shown in Fig. 2. In this manner, the extra thickness of the window assembly will extend to one side only of each door portion.
By orientating the adaptor frames 20 in opposite senses or S directions in the two door portions 12, 13, the window assemblies will protrude in opposite (diverging) directions, and therefore will not interfere with the opening of the door This allows each window assembly to be opened regardless of whether the door is opened or closed.
The window assemblies in docr portions 12, 13 are reversed left-to-right in orientation as shown in Fig. 1.
A particular advantage of the door 10 illustrated in Fig. 1, is that it enables up to 75t of the wall opening to be used for ventilation. In each window assembly, the movable S portion is approximately the same size as the fixed portion.
By opening each movable window portion fully, and opening the movable door portion 13 half way, the fixed window portions will overlap, leaving approximately three quarters of the total aperture open for ventilation.
Even when the door is closed, 50% of the available aperture can be used for ventilation.
The abovedescribed door enables security to be maintained, while permitting variable ventilation.
Although the door has been described with reference
I
2S d t. 2 i 4 9 0 to its conversion from a conventional sliding door, it will be apparent to those skilled in the art that the door can be constructed in the first instance to incorporate the sliding window assemblies. If the window assemblies are installed at manufacturing stage, the fitting 21 can be incorporated onto the frame of each window assembly, thereby avoiding the need for a separate adaptor frame.
The foregoing describes only one embodiment of the invention, and modifications which are obvious to those skilled in the art may be made thereto without departing from the scope of the invention. For example, each door portion may be slidable, and each window portion within each window assembly may be slidable.
