Abstract

A window comprises a frame and a window sash 5 slidable vertically within the frame. The sash 5 is provided at the sides of its lower edge with downwardly depending horns 7. The sash 5 is pivotable within the frame, about points on the frame at or near the lower edges of the horns 7. The sash 5 preferably pivots about one or more rigid bars (72, Fig 6) secured to the sash 5 with the end of the bar located in the frame. <IMAGE>

Description

Title - Window This invention relates to a window, in particular to a vertically sliding window having decorative features.
Wooden window frames, particularly in older properties, are prone to rotting and require replacement. In addition, older window frames are generally single-glazed and it is often desirable for these to be replaced by double-glazed units, for improved heat insulation etc.
One form of window, which is particularly common on older properties, has vertically sliding sashes. Modern forms of such window are generally constructed in such a way that the sashes can not only be slid vertically, but can also be tilted inwardly.
The sashes of vertically sliding windows in older properties are, however, often provided with 'horns' at the base of the upper sash, adjacent the window frame. The horns are often decoratively shaped or carved, and it is desirable that replacement windows should have the same form, eg where only some of the windows in a particular property are replaced or to retain the original character of a property where all the windows are replaced. Indeed, conservation regulations may require that replacement windows have the same appearance as the original windows.
Where horns are provided on a vertically sliding window sash, however, a problem which has hitherto been encountered is that the horns interfere with the tilting action of the window, with the result that this feature cannot be used.
One possible solution to this problem is described in our co-pending UK Patent Application No 9123025.0. This discloses a window in which the horns are hingedly connected to the lower edge of the upper sash. Whilst this approach has some merit, it is mechanically complex and the junction of the window frame and the horn is frequently visible and unsightly.
There has now been devised a form of vertically sliding window which overcomes or substantially mitigates the above-mentioned disadvantages.
According to the invention, a window comprises a frame and a window sash slidable vertically within the frame, the sash being provided-at the sides of its lower edge with downwardly depending horns and being pivotable within the frame, wherein the sash pivots about points on the window frame at or near the lower edges of the horns.
The window according to the invention is advantageous primarily in that it enables the use of horns on tiltable windows, providing the benefits of such windows in properties which for one reason or another require windows with horns. The construction is relatively simple and the horns may be securely fixed to the window sash, or formed integrally therewith, so that no join between the two components is visible. Although the window is of particular utility in the replacement of windows in older properties, it may also be used in new properties, where the decorative effect of horns is desired.
Conveniently, the sash pivots about bars of suitably rigid material, eg steel, which are secured to the sash, eg by means of screws. The bar protrudes from the lower part of the horn and locates in the window frame. The bar may be strengthened by a brace, which may be welded to the bar and secured to the lower cross-member of the sash. There are preferably two pivot bars, one at each side of the sash.
The components of the window may be of any materials conventionally used for such components. The window frame and sash, including the horns, may, for example, be of timber, but most conveniently are of plastics material, eg extruded or moulded PVC. Where the horns are moulded they may be provided with a veneer of extruded PVC to provide a good visual match with the sash material.
The horns may be made in any desired shape and may be formed integrally with the window sash, or part of the window sash, or may be fixed to the sash, eg by means of adhesive, welding or with an interlocking fit.
The invention will now be described in more detail, by way of illustration only, with reference to the accompanying drawings, in which Figure 1 is a front elevational view of a window according to the invention having upper and lower vertically sliding sashes, Figure 2A is a perspective view of the region of the window of Figure 1 which is encircled and marked II in Figure 1, Figure 2B is a perspective view of the same region as shown in Figure 2A with the lower sash tilted inwardly, Figure 2C is a further perspective view of the same region with both upper and lower sashes tilted inwardly, Figure 3 is a vertical sectional view of the window of Figure 1, Figure 4 is a horizontal sectional view of the window of Figure 1 with the upper and lower sashes overlapping, Figure 5 is a rear elevational view of a horn, two of which are fitted to the window of Figure 1, Figure 6 is a front elevational view of a pivot bar assembly, two of which are fitted to the upper sash of the window of Figure 1 and Figure 7 is a plan view of the bar assembly of Figure 6.
Referring first to Figure 1, a window comprises a frame formed from right and left jambs 1,2, a head 3 and a sill 4, all of which are formed from PVC extrusions. Slidably mounted within the frame are upper and lower sashes 5,6, the lower sash 6 being mounted inwardly of the upper sash 5.
As can be seen most clearly from Figure 2A, the upper sash 5 is.
provided at its base with two downwardly depending decorative horns 7. The horns 7 are connected by means of interlocking detents 61,62 (visible in Figures 3 and 6) to the upper sash 5 at the inward lower edge thereof.
Both the upper sash 5 and the lower sash 6 are tiltable inwardly to provide increased ventilation or to facilitate cleaning.
Figure 2B shows the lower sash 6 in the tilted position. The upper sash 5 may also be tilted, as shown in Figure 2C, from which it can be seen that the upper sash 5 pivots about a point near the lower edge of the horn 7.
Figures 3 and 4 show constructional details of the window. The right and left jambs 1,2, the head 3 and the sill 4 each contain steel reinforcements 8. The upper sash 5 and lower sash 6 each comprise frames formed from PVC extrusions 9 and contain a sealed double-glazed unit 10 which is held in place by an extruded PVC glazing bead 11.
A pivot bar assembly about which the upper sash 5 pivots is shown in Figures 7 and 8. This comprises a vertical bar 71, the lower end of which is narrowed and formed into a horizontal limb 72.
The horizontal limb 72 locates in the window frame in a conventional manner. A horizontal brace 73 is welded to the vertical bar 71. The pivot bar is fixed to the upper sash 5 by means of screws passing through apertures provided in both the vertical bar 71 and the horizontal limb 72. The lower portion of the vertical bar 71 is located within the horn 7 such that the pivot point is adjacent the lower edge of the horn 7.
