The inner frame (10) is formed from lengths of an elongate component (22) whose cross-section is of an inverted T or substantially so. One first part of a hinge has a wall (24) upstanding from an outer part of the cross-piece (26) of the component (22) parallel to and spaced outwardly from the stem (28) of the component (22). The wall (24) terminates at its upper end in a cylindrical formation engageable by an elongate clip (32) of C-shape cross-section of a second part (34) of the hinge provided on the outer frame (12).

Description

WINDOW FRAME STRUCTURES AND COMPONENTS THEREFOR.
This invention relates to window frame structures for use primarily, but not necessarily, for openable roof windows, particularly, but not necessarily, to be fitted in a support structure provided on a building, for example a conservatory, in which single glazed or double glazed units are used.
Accordingly, the present invention is a window frame structure comprising an inner frame and an outer frame, both being of rectangular shape or substantially so, the inner frame being intended to be secured to a support structure with the outer frame hingedly connected to the inner frame along one side thereof, the inner frame being formed from lengths of an elongate component whose cross-section is of an inverted T or substantially so, at least one first part of a hinge having a wall upstanding from an outer part of the cross-piece of the component parallel to and spaced outwardly from the stem of the component, the wall terminating at its upper end in a cylindrical formation engagable by an elongate clip of C-shape cross-section of a second part of the hinge provided on the outer frame.
Preferably, the component has a second part to increase the depth of the cross-piece, the second part being securable to the first part on the side of the cross-piece remote from the stem in either of two positions depending on whether the window frame structure is to be fitted to a support structure suitable for single or double glazing units. The second part is desirably of channel cross-section having clip elements along the outer ends of its limbs, the clip elements being matable with complementary pairs of clip members provided at each of the two positions on the cross-piece.
Preferably also, the second part of the hinge is of substantial inverted U-shape with the elongate clip provided at the outer edge of an outer limb.
Preferably further, the inner and outer frames are fabricated from elongate components of plastics material and the parts of the hinge are of metal or an alloy thereof, the parts of the hinge being secured to the respective part of the frames.
An embodiment of the present invention will now be described, by way of example, with reference to the accompanying drawings, in which:-
Fig. 1 is a perspective view of a window frame structure according to the present invention shown from inside with an outer frame hinged open from an inner frame;
Fig. 2 is a longitudinal cross-sectional view of a window frame structure integrated into a support structure shown in this embodiment as a glazed roof of a lean-to conservatory to a larger scale than Fig. 1 ;
Fig. 3 is a transverse cross-sectional view of a window frame structure fitted between two transom rails and to a smaller scale than Fig. 2;
Figs. 4 and 5 are cross-sectional details of a window frame structure at a hinged side showing an outer frame and an inner frame relative to a support structure to which the window frame structure is mountable, the window frame structure being shown respectively in a double glazed fitment on the support structure and in a single glazed fitment on the support structure; and
Figs. 6 and 7 are cross-sectional details of a window frame structure as shown respectively in Figs. 1 and 2 but with a modified inner frame.
Referring to Figs. 1 to 5 of the drawings, a window frame structure comprises an inner frame 10 and an outer frame 12, both frames 10, 12 being of complementary rectangular shape as shown. The inner frame 10 is intended to be secured to a support structure 14 with the outer frame 12 hingedly connected to the inner frame 10 along a top side thereof. The outer frame 12 is formed, with mitred corners, from four lengths of an elongate channel member 16 to the inward side of an inner limb of which a holding C-shaped channel 18 is provided to hold a double glazed unit 20. The inner frame 10 is formed, with mitred corners, from four lengths of an elongate component 22 whose cross- section is of an inverted T or substantially so.
A first part of a hinge has a wall 24 upstanding as shown from an outer part of the cross-piece 26 of the component 22 parallel to and spaced outwardly from the stem 28 of the component 22. The wall 24 terminates at its upper end in a cylindrical formation 30 engagable by an elongate clip 32 of C-shape cross-section of a second part of the hinge on the outer frame 12. A continuous length of a first part is provided but a series of spaced shorter lengths can be used.
The component 22 has a second part 34 to increase the depth of the cross-piece 26. The second part 34 is securable to the first part on the side of the cross- piece 26 remote from the stem 28 in either of two positions depending on whether the window frame structure is to be fitted to a support structure 14 suitable for single or double glazing units as shown in Figs. 5 and 4 respectively. The second part 34 is of channel cross-section having clip elements 36 along the outer ends of its limbs as shown. The clip elements 36 are matable with complementary pairs of clip members 38 provided at each of the two positions on the cross-piece 26 as shown.
The second part of the hinge is integral with a substantial inverted U-shape component 40 of the member 16 with the elongate clip 32 provided at the outer edge of an outer limb as shown. The other limb of the inverted U-shape component 40 has an extension flange 42, the other lirnb and flange 42 forming a portion of the holding channel 18.
The inner and outer frames 10, 12 are fabricated from elongate components of plastics material and the parts of the hinge are of metal or an alloy thereof. The parts of the hinge are secured to the respective part of the frames 10, 12.
A window frame structure as described above is fitted to a support structure 14, for example a sloping glazed roof of a lean-to conservatory as shown in Figs 1 and 2, or an upright support as shown in Figs. 4, 5, 6 and 7, in the manner shown in the drawings and as described above. The hinged side is uppermost. The stem 28 prevents rain or water entering the window. Window catches 50 can be fitted on the side opposite to the hinged side as shown in Figs. 1 and 2. In Fig. 2, the structure is shown at the top of the roof and a fitment 52 is secured along the bottom of the inner frame 10 to provide a channel into which glazing sheets or glazing units 54 can be fitted as shown. The inner end of the cross-piece 26 has an integral flyscreen holding groove 44 for fitment of a flyscreen (not shown) across the opening defined by the inner window frame 10.
A spacer 56 is provided to be fitted internally of a single glazing sheet 58 as shown in Fig. 5.
In a modification as shown in Figs. 3 and 4, the second part 34 of the component 22 is constituted by a wooden block for use where the support structure 14 is also made from wood.
Variations and other modifications can be made without departing from the scope of the invention as described above.
