Definitions

• This invention relates to window and door frames as well as to doors.
• the invention also relates to methods for the preparation of window and door frames and doors.
• the invention provides a window or door frame or a door having a frame construction, wherein the frame comprises a plurality of frame members wherein said frame members are of extruded box section divided into two or more internal sections by at least one longitudinal internal wall or web and wherein joints between said frame members are formed with one or more prefabricated jointing members each having one or more spigots or fingers engaging with said frame members by insertion of said spigots or fingers into an internal section of the frame members, at least two spigots or fingers being inserted into each frame member at said joints.
• the invention provides a method of assembling a window or door frame or a door having a frame construction, which comprises cutting lengths of the extruded box section material according to the dimensions of the required frame to form a plurality of -frame members and engaging the prefabricated jointing members with said frame members by insertion into the box section of the frame members.
• the invention provides a kit of parts for assembly into a window or door frame or a frame for a door having a frame construction comprising one or more lengths of the extruded box section material for cutting to form frame members, together with one or more of the prefabricated jointing members for engaging with said frame members by insertion into the box section of said frame members.
• the frame members are conveniently formed from extruded metal
• the extruded material being of box section.
• a window pane or glazed door is required (e.g. glazed with glass or plastics)
• the pane may be attached to the frame by a putty-less sealing strip, which strip may be secured to the window frame using conventional cavity fixings.
• frames for doors may be finished by panelling or facing with wood or other decorative material.
• the frame members may have a square or rectangular cross-section with a single longitudinal internal wall. If desired, however, the frame members may be extruded with a more complicated cross-sectional shape, e.g.
• door frame members may have a simple square or rectangular box cross-section or alternatively more complicated shapes may be adopted as desired.
• box section of the window or door frame members is divided into two or more internal sections by one or more longitudinal internal walls; this being advantageous since the internal walls serve to strengthen and improve the rigidity of the frame.
• the frame members can be filled with an insulating or fire-proof material.
• Prefabricated jointing members for use according to the invention may be, for example, L-shaped to provide corner joints such as between the sill and stiles of a window, T-shaped to provide joints between the stiles of a window and a transom, or of more complex arrangement such as to provide joints between a transom and a mullion or joints in a bay window assembly.
• the jointing members may in one embodiment have a similar external finish and cross-sectional profile to the frame members to be joined so that the assembled window or door frame has a pleasing appearance.
• the cross-sectional profile of the jointing members will similarly generally correspond to that of the frame members, so that the jointing members will have a plurality of spigots or fingers fitting into at least some of the internal sections of the frame members. This further serves to strengthen and make rigid the assembled frames.
• the joints between frame members may be formed by mitring the frame members and inserting one or more jointing members into the internal sections of the frame members. Simple L-shaped jointing members may be conveniently used, and these will be hidden within the joint when the frame is assembled.
• one or more timber pieces or other supporting members e.g. of plastics or metal, may be inserted into the box section of the frame members to provide support e.g. for hinges, handles or locks.
• Figure 1 is a front elevatio ⁇ al view of an assembled window frame according to one embodiment of the invention.
• Figure 2 is a partially exploded perspective view of a part of an L- shaped corner joint where the frame members are mitred;
• FIG 3 is a perspective view of a T-shaped jointing member for use in the assembly of the frame shown in Figure 1;
• Figure 4 diagrammatically shows in cross-section a putty-less sealing strip and glazing pane attached to a frame according to the invention;
• Figure 5 diagrammatically shows a perspective view of a corner jointing member which may be used in an embodiment of the invention when the frame member is provided with a single longitudinal internal dividing wall;
• Figure 6 shows a cross-sectional view of a transom frame member having three internal walls.
• FIG. 1 shows a window frame according to an embodiment of the invention.
• the frame comprises seven frame members 1-4 which are formed from extruded UPVC of square box section. The lengths of the frame members are selected according to the dimensions of the window opening to be framed.
• the head 1 and sill 2 frame members are joined to the stile members 3a and 3b by L-shaped jointing members 5, e.g. shown in Figure 5.
• the optional transom member 4 is joined to the stile members 3a and 3b by T-shaped jointing members 6, which may be as shown Figure 3.
• one or more mullion members could be provided in the frame, which mullion members may be joined to the head and sill members by T-joints and to the transom by a +-joint.
• transom or mullion members may be cut to size and simply butted to the frame members and secured thereto, e.g. with screws.
• the jointing members 5 and 6 engage with the frame members by insertion into the box section of the frame members.
• the jointing members are provided with arms or spigots for insertion into the box section of the frame, the arms preferably being of similar cross- sectional size and profile as the inside of the box section.
• the arms are advantageously of such a size as to provide a tight fit in the frame members, and if desired they may be provided with one or more circumferential ribs to ensure a secure fixing to the frame members.
• the arms may, if desired, be slightly tapered in order to make insertion in the frame members easier.
• each jointing member is conveniently of similar size and appearance as the exterior of the frame members so that the jointing members are as unobtrusive as possible in the assembled product.
• the jointing members will generally be prepared from the same material as the frame members, e.g. UPVC or aluminium.
• the jointing member shown in Figure 5 is provided with two spigots 7 and may be used where the frame member has a single internal dividing wall so that the spigots have a similar cross-section to the internal cross-section of the frame member.
• the jointing members may be formed by injection moulding or extrusion. Alternatively the spigots may be separately formed and fixed to the body of the jointing members, e.g. by glueing or welding, either before or after being inserted into the corresponding frame members.
• Figure 6 shows a more complicated cross-sectional view of a transom frame member having three internal walls, this being a very strong and rigid configuration.
• the corresponding jointing members for use with such a frame may have up to four spigots for insertion into the internal sections of the frame member.
• the frame member 20 is mitred for jointing with a similar frame member (not shown).
• L-shaped jointing members 21, which in this case have different sizes, are inserted into the internal sections formed by the longitudinal walls 22. If desired a third L- shaped jointing member may be inserted into the internal section 23.
• the joint may be secured by gluing and/or screwing as necessary and/or desired.
• the frames according to the present invention may be simply and easily assembled by the unskilled worker and it will be particularly appreciated that assembly does not require any skills in the production of conventional joints.
• the frame shown in Figure 1 may be simply prepared from a kit of parts including a sufficient number of joints 5 and 6 and a sufficient length of extruded material to form the frame members 1-4.
• appropriate lengths of extruded material are cut to form the head 1 and sill 2 frame members.
• the stile frame members 3a and 3b are cut.
• the frame members can then be assembled together by inserting the jointing members. Where the jointing members form a tight fit in the frame member it may be necessary to hammer the jointing members gently into place.
• the frames may be assembled with welding of. the joints, e.g. heat or solvent welding when the frames are fabricated from plastics material, or the joints may be secured by screws, rivets or the like.
• the window pane or panes may be fitted.
• the pane may conveniently be fitted using a seal strip as shown in Figure 4.
• This comprises an elongate aluminium extrusion 1 which may be fixed to the frame 2 using conventional fixings 3.
• the sealing strip conveniently incorporates a rubber weathersealing strip 14' and a rubber pane sealing strip 15.
• the pane 16 is generally glass or plastics.
• the portion of the window above the transom may be fitted with louvred openings using conventional techniques.
• opening window sashes may be fitted to the window frame as desired, again using methods known in the art.
• the frame When the frame is fully assembled it may be fixed into the window or door opening of the building. This may be effected in conventional fashion.
• the frames according to the invention are primarily intended for use as replacement frames although their utility is not limited to such use.
• the frames may be used in new or altered buildings.
• window frames according to the invention are principally intended for use as primary glazing systems (incorporating single or double glazing as desired). They may, however, be used in conjunction with existing windows to provide a secondary glazing system.
• Doors according to the invention may be prepared for internal or external use and can be constructed to any desired dimensions. They may thus be used, for example, as internal or external doors in domestic or commerical buildings or as other types of doors such as garage doors.
