Abstract

A sash window assembly has a lower panel (22, figure 1) which slides vertically to open the window, and balancers 23 disposed to each side of the panel to take the weight of the panel. The balancers are connected by hinge mechanisms, preferably a pivot pin 25, to the panel at the upper edge, whereby the panel may be raised vertically and then hinged about a generally horizontal axis, to allow escape through the open window. The pivoted sash may be propped open by struts 27, preferably spring struts.

SASH WINDOW ASSEMBLIES
This invention relates to sash window assemblies, intended for fitting into a window opening in a building.
Sash windows are widely used in both domestic dwellings and offices, in 5 view of the enhanced aesthetic appearance of a building having such windows. Typically, there is a frame secured to the window opening and a pair of vertically slidable panels disposed within the frame such that either panel may be slid to lie alongside the other, to open the window. Each slidable panel has, on each side, a balancer to take at least some of the weight of the panel, to 10 facilitate opening and also the maintenance of the panel at an opened setting. Originally, the balancers comprised weights suspended on cords connected to the panels but more recently compact balancers incorporating spring mechanisms have been employed.
A problem with sash windows is that the maximum possible opening is 15 normally significantly less than half the total area of the frame. This is because, for many designs of sash windows, the two panels cannot be wholly overlapped and so the maximum open area is significantly less than the area of the lower panel itself. Moreover, for windows which are wider than high, the maximum vertical extent of the opening may be relatively small. This leads to 20 significant problems, in the event that the window is to be used as an escape from a building incorporating the window, for example in the case of fire or some other emergency.
Recent regulations in the United Kingdom have required all buildings to have at least one so-called fire window that can serve as an escape route in the 25 event of an emergency. In view of the problems outlined above, many

conventional designs of sash windows do not meet the criteria laid down for fire windows.
It is known to provide a sash window specifically adapted to facilitate external cleaning from within a building incorporating the window. In such a 5 window, at least one of the panels, but usually the lower panel, is hinged to the outer frame by a pair of pins projecting laterally from the window adjacent the lower edge thereof. The upper edge of the window is provided with retractable clips, so that when the clips project, the panel may slide normally, but when retracted the lower panel may be hinged inwardly, about the lower edge of the 10 panel with the axis of hinging being defined by the pair of pins. However, when hinged in this way, the inwardly projecting panel restricts access to the window opening and it is at least as difficult, if not more so, to climb through a window with the lower panel hinged inwardly than were the lower panel simply raised vertically.
15 In an attempt to address the problem of providing a fire window with a sash window assembly, the present invention provides a sash window assembly having a lower panel which is slidable vertically upwardly to open the window and a pair of balancers disposed one to each side of the panel to take at least some of the weight of the panel, in which assembly the balancers are 20 connected to the panel at or in the vicinity of the upper edge of the panel by means of respective hinge mechanisms, whereby the panel may be raised vertically and then be hinged about a generally horizontal axis out of the plane of the window opening, to facilitate egress through the open window, from a building in which the window assembly is fitted.

It will be appreciated that with this invention, the opening of a sash window assembly which can be achieved is significantly greater than were the lower panel merely lifted vertically, or hinged inwardly, about its lower edge. By appropriate configuration, the window assembly can meet the criteria laid down 5 for a fire window, so that sash windows may be incorporated throughout a building.
By way of example, a specific embodiment of sash window assembly of this invention will now be described in detail, reference being made to the accompanying drawings, in which:-10 Figure 1 is an elevation of the window assembly, when opened by hinging movement of the lower panel; and
Figure 2 is a diagrammatic side view of the window of Figure 1.
Referring to Figures 1 and 1, there is shown a sash window assembly of this invention. In this embodiment, there is provided a frame 20 which is fitted 15 into the window opening in a wall and which defines two parallel channels in which are slidably mounted upper and lower window panels 21 and 22. The upper panel 21 is mounted in the outer channel and the lower panel 22 in the inner channel. Both panels are provided with a pair of balancers but in the case of the lower panel 22, the balancer 23 (Figure 2) is fitted between the 20 upper edge 24 of the frame 20 and the upper edge of the lower panel 22. The connection (on each side) between the upper edge of the lower panel and the balancer 23 is by means of a pivot pin 25, which extends into the channel so as to constrain the upper edge of the panel for sliding movement with respect to the frame 20. In order to allow the lower panel 22 to slide upwardly to a
P114044-SP-01.doc
-4-
sufficient extent for normal window operation, a relatively compact form of balancer 23 is employed, typically of telescopic form and exerting a relatively high spring force. The balancer is shown extending above the upper edge of the panel, but could as easily be arranged below this upper edge if suitably 5 configured.
A locking mechanism is provided on the lower edge 26 of the lower panel 22, which mechanism includes a pair of lugs adapted normally to project laterally into the channels of the frame 20, so as to constrain the entire panel for sliding movement with respect to the frame. However, when the mechanism 10 is unlocked, the lugs are withdrawn from the channels so that the lower panel 22 may hinge inwardly of the building in which the sash window is fitted, as shown in Figures 1 and 2. By first raising the lower panel to its maximum extent and then hinging the lower panel inwardly, a significantly wider opening through the window frame is achieved, approximately equal to one half of the 15 area defined by the frame.
A pair of struts 27 may be provided between the lower panel 22 and the frame, to support the lower panel in its inwardly-hinged disposition. Such struts may attempt to balance the weight of the panel and so, for example, could be spring struts or may simply be mechanical struts which lock out when the lower 20 panel 22 has fully been hinged inwardly, so as thereafter to maintain the lower panel in that position.

Claims (1)

1. A sash window assembly having a lower panel which is slidable vertically upwardly to open the window and a pair of balancers disposed one to each side of the panel to take at least some of the weight of the panel, in which
5 assembly the balancers are connected to the panel at or in the vicinity of the upper edge of the panel by means of respective hinge mechanisms, whereby the panel may be raised vertically and then be hinged about a generally horizontal axis out of the plane of the window opening, to facilitate egress through the open window, from a building in which the window assembly is 10 fitted.
2. A sash window assembly as claimed in claim 1, wherein a locking mechanism is provided at the lower edge of the lower panel, to constrain the lower panel for sliding movement within the frame until the mechanism has been unlocked.
15 3. A sash window assembly as claimed in claim 1 or claim 2, wherein a pair of struts is provided one on each side respectively of the lower panel, to support the lower panel when hinged away from its normal position.
4. A sash window assembly as claimed in claim 3, wherein each of the pair of struts is a spring strut adapted to support at least part of the weight of the
20 lower panel.
5. A sash window assembly substantially as hereinbefore described, with reference to and as illustrated in Figures 5 and 6 of the accompanying drawings.
