Description

IMPROVEMENTS IN AND RELATED TO THE INSTALLATION OF WINDOWS DESCRIPTION This invention concerns improvements in and related to the installation of windows. Generally, a window frame is mounted on a window edge, such that the part of the edge extends out of the window frame. At the rear of the frame, for example on the inside of the construction, a frame is assembled against the edge and / or the frame. Usually when installing u-PVC replacement frames, for example, the original frame of the window is left in position and only one u-PVC frame is adjusted. The union of the frame with the edge and / or the frame needs to be made up for the sake of appearance. Even if the window frame is also replaced, the problem of making a clean joint between the frame and the frame still exists possibly due to irregularities in the opening of the window. A proposal to deal with this problem was made in the GB patent 2287273A, which describes a window frame system comprising a window frame assembling a window edge member, a window frame mounted on a part of the edge of the window and a convex molding strip to make up the attachment point of the window. frame with the frame of the window and / or edge, wherein the convex molding strip comprises a cover part and a channel section depending from the cover part located in an upright part of the window frame system, wherein the Convex molding strip is locatable in position after frame assembly for window frame and edge. Even this arrangement is not entirely satisfactory because of the possibility of unevenness of the opening of the window causing the convex molding not to seal adequately along its entire length. Additionally, there is no possibility to adjust the lateral position of the frame relative to the edge of the window.

An object of this invention is to provide a solution to the aforementioned problems of window installation. In accordance with this invention, it is proposed that a combined window and edge frame be provided, for example, in a one-piece construction. Preferably the combination of the window frame and the edge will be formed by extrusion of plastic material, especially u-PVC. The preferred combination of the window frame and the edge of the invention have an upper wall and a lower wall connected by boxes to form ducts therein. At the end of the window frame the combined component is preferably molded to provide upper rounded profile and preferably has a return at its bottom. At the end of the window frame, the combined component preferably has an upper wall with a downward slope directing a protrusion extending below the bottom wall of the component where water falling from the edge may spill on the overhang instead of return along the bottom of the component and in the brick support work. Between the parts of the frame and the edge, the combined component has a part in which a window frame can be mounted. That part preferably has means for lateral adjustment in the positioning of the frame relative to the frame / edge. Due to the lateral adjustment, a normal adjustment to the plane of the window is intended. Preferably the combined component has a series of locations for positioning the element that is also located in a part of the window frame. The window frame may have a channel or groove in its lower part and the combined element may have a series of parallel grooves in its upper surface, wherein a peg, strip or the like may be located in the frame and one of the grooves in the frame. combined component according to the desired position of the window frame relative to the frame / edge component.

This invention will now be further described, by means of examples only, with reference to the accompanying drawings, which is a section through the composition of the frame of the window and the edge according to the invention: Referring to the drawings that are accompanied, a double brick wall have a ridge and a frame 12 mounted on the wall and a window frame mounted on the edge / frame of the window. The edge of the window and the frame 12 are made as a hollow plastic extrusion, typically u-PVC. The edge of the window and the frame have an upper wall 16, a lower wall 18 and walls at the end 20 and 22 enclosing a plurality of conduits 50, 52, 54, 56, 60, 62, 64, 66, 68, 70 and 72 formed by the boxes 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 46 and 48 connecting the upper and lower walls. The lower wall 18 is straight apart from two channels 74, 76 in its lower part. The upper wall 16 has a first part 78 forming a window frame for the interior of a construction that is parallel to the lower wall over most of its width. At one end the first part of the upper wall 18 is curved at 80 to find the end of the wall 20 extending below the lower wall as does the box 24. The extension of the box 24 has on its outer face a duct 82 projecting back parallel to the lower wall. This provides a clean and pleasing appearance to the window frame. At its opposite end the first portion 78 of the upper wall 16 has an upward sloping portion 84 facing a second part 86 of the edge / frame in which the frame of the window 14 is mounted. The part 86 of the edge / frame has a first section 88 having a series of parallel grooves 90 in its upper surface and a second flat section 92. The covers of the ridges forming the grooves 90 are flush with the cover of the flat section 92. the slots 90 receive in one or the other a pin or strip 94. The pin or strip 94 is also located in a channel 96 in the lower part of the frame of the window 14. When locating the pin or strip 94 in a slot 90 different, adjustments can be made to the position of the frame of the window 14 relative to the edge / frame 12 of the window. The upper wall 16 has a third section 96 forming the edge of the window. The top wall 16 slopes downwardly on this section and curves downward to form the end or front wall 22. The front wall 22 continues below the level of the bottom wall and is weighted towards a downward flank 98 of the bottom wall for form a projection This is so that the water that falls on the ridge travels below the upper wall 16 and below the front wall 22 where the water drops will form and fall out of the ridge instead of traveling back below the ridge. , or which is to avoid water penetration between the edge and the wall. Accordingly, the invention provides a one-piece window frame and frame that is easy to adjust and provides for variations in position of a window frame as well as simplifying the installation of u-PVC windows without the need for adjustments for accommodate the frame of a window
