Abstract

A mounting means for an outer frame or part-frame 4 of a door or window assembly in an opening defined by a building structure 1, the means comprising two parts for attachment to the frame, flat member 11, and building structure, bracket 9, respectively, said parts being provided with interengageable formations 17. These formations are arranged when disengaged to permit movement of the frame in the opening in a direction transverse to the opposite faces 1a, 1b of the structure surrounding the opening, and when engaged, to prevent such movement thereby to locate the frame in position relative to said faces. Means is also provided to secure the parts together with said formations in the engaged position and this may be a bolt. The said formations may consist of co-operating ridges and grooves. There may also be provided a cover member 18 and attachment means to secure it to at least one of the said parts to cover any gap between the frame 4 and the building structure 1. A moulding member may also be fitted to cover meeting end portions of separate cover members.

Description

2361501 DOOR AND WINDOW ASSEMBLIES This invention relates to door and

window assemblies.

In particular, the invention is concerned with the mounting of such an assembly comprising an outer frame or part-frame in an opening defined by a 5 building structure, for example brickwork.

One problem which is often encountered when installing such a door or window assembly is that the thickness of building structures may vary and as a result it may be difficult to position the outer frame or part-frame correctly in the opening in the structure with respect to the inner or outer face of the structure around the opening A further problem is that there may be a gap between parts of the outer frame or part-frame and the building structure and covering this gap usually involves positioning separate masking elements and securing them to the building structure.

With the object of overcoming the first problem referred to above, the present invention provides mounting means for an outer frame or part-frame of a door or window assembly in an opening defined by a building structure, said means comprising two parts for attachment respectively to the frame and the building structure, said parts being provided with interengageable formations arranged when disengaged to permit movement of the frame in the opening in a direction transverse to the opposite faces of the structure surrounding the 2 opening and when engaged to prevent such movement thereby to locate the frame in position relative to said faces, means also being provided to secure the parts together with said formations in the engaged position.

The said formations may be interlocking formations engageable with and disengageable from each other simply by relative movement between the parts in a direction generally parallel to the said opposed faces of the structure. In a preferred embodiment the formations are cooperating ridges and grooves provided on the respective parts. The means for securing the parts together may be bolts.

In order to overcome the second problem mentioned above, the mounting means may further include a cover member and attachment means for securing the member to at least one of the said parts so that, in use, the member covers any gap between the portion of the frame to which one of the parts is attached and the opposed portion of the building structure to which the other part is attached.

The said attachment means may comprise interengageable flange and channel formations and/or interlocking formations provided on the cover and one of the parts respectively.

The invention will now be described, by way of example, with reference to the accompanying drawing which is a horizontal sectional view of one side of a sash window assembly.

3 The window assembly shown in the drawing is mounted in a building structure 1, for example brickwork and/or a wooden frame, defining a rectangular opening having an inwardly extending lip 2 defining a rebate 3 on all four sides of the opening. The window assembly comprises two sashes (not 5 shown) mounted for vertical sliding movement in an outer rectangular frame 4. Each sash comprises a rectangular frame formed from plastics extrusions and containing a pane of glass. The outer frame 4 also comprises plastics extrusions which are formed to provide along the vertical side members of the frame of which one, designated 5, is seen in the drawing, two inwardly facing side-by-side channels 6 which receive the adjacent side members of the respective sashes so that they are slidable up and down in the channels. The side member 5 incorporates a metal reinforcement 7.

The outer frame 4 of the sash window assembly is mounted in the rebate 3 around the opening in the structure I by mounting means according to the invention, a seal 8 being provided between the lip of the structure I and the outer frame 4.

The assembly may have four mounting means of the form to be described, arranged along the respective sides of the frame, or only three such means arranged along the two vertical sides and the horizontal upper side of the frame, the horizontal lower side of the frame in this case being provided with an ordinary sill.

4 The mounting means on each side of the outer frame comprises a number of spaced support brackets of generally L-shape in cross section, one of which, designated 9, is shown in the drawing. These brackets are secured to the structure I by screws 10. The mounting means further comprises a generally flat member 11 secured to the outer frame 4 by screws 12. Each bracket 9 is arranged with one limb 9a flat against the inner face la of the structure I and the other limb 9b extending into the rebate 3 parallel to the opposed face lb of the structure. Each member I I is connected to the limbs 9b of the opposed brackets 9 by bolts 13 passing through slots 14 in the limbs 9b and engaged with nuts 15 held captive in channels 16 formed in the member 11. The limb 9b of the member 9 and the member I I are formed with opposed flat faces 9c, I I a which are provided with interengageable ridges and grooves 17 in the nature of serrations which extend longitudinally of the adjacent face lb of the structure.

The bolts 13 secured to the member I I and hence to the outer frame 4, are movable, when loosened, along the slots 14 in the brackets 9, to enable the position of the outer frame to be adjusted in the direction of arrow A relative to the structure 1, thereby catering for structures of different thicknesses. Such adjustment is performed before fixing the brackets 9 to the structure I by means of the screws 10 to enable access to be had to the bolts 13. The bolts are then tightened so that the opposed ridges and grooves 17 are brought into close contact with one another thereby preventing movement of the member I I in the direction of arrow A relative to the brackets 9.

When all three or four mounting means, as the case may be, have been adjusted in this way and the window assembly has been mounted in place in the correct, adjusted position, a cover or trim 18 is fitted to the assembly along each side to cover the gap between the structure I and the outer frame 4 and to hide the associated mounting means comprising the brackets 9 and member 11. This cover or trim is in the form of a profile provided with grooves 19,21 having serrated side surfaces for receiving with a push fit similarly serrated flanges 20,22 provided on the bracket 9 and with a channel for receiving a further flange 23 provided on the bracket whereby the cover or trim is securely held in place.

A moulding (not shown) may be provided to cover the profile 18 at its ends adjacent to the ends of adjoining profiles. Alternatively the adjacent ends of profiles may be cut to form a mitre joint.

It is to be understood that the scope of the present invention is not to be limited by the example illustrated in the accompanying drawing. In particular the invention is applicable to other types of window and to doors. Also, the invention includes any novel and inventive feature disclosed herein either alone or in combination with any one or more other such features.
