Description

2338978 SASH WINDOWS.
Sash windows in general comprise a pair of sliding window panels, each having a counterweight acting over a pulley or else having spiral balances. Neither of these arrangements is successful, particularly in coastal areas due to corrosion and this often results in the panels becoming very difficult to slide. Another problem is the failure of the cord or spiral with the result that the panel do not stay in chosen position and may even crash down.
It is an object of the present invention to provide a very simple and inexpensive arrangement for a sash window which avoid or at least minimises the difficulties referred to above. Also provide better safety during opening and closing of window.
According to the invention a sash window arrangement includes a pair of window panels slidable in a frame and being connected together with a tie whereby movement of one causes a corresponding movement in the opposite direction of the other and being at 2:1 ratio in any relative position of the two panels.
The tie or ties may operate over direction changing means such as pulley and these may be located neatly in the frame and if possible, hidden from view. It is possible to use plastic pulleys and the cable may be of stainless steel, preferably swaged with copper, In many cases it is possible to replace existing arrangements with the arrangement of the invention and in certain circumstances use may be made of existing brackets and other formations to mount the pulleys and anchor ties.
As most sash windows involve panels of the same mass, the arrangement of the invention makes use of the counter balance, friction assuring that the two panels remain in the position chosen. The invention can be used even where the panels are not of the same mass. The fact that there is corresponding movement is considered an advantage because the main object of sash windows is to provide a gap at the bottom and at the top for exchange of cool air in at the bottom gap and expulsion of wann air through the top gap.
2.
ENMODUVENT OF THE INVENYION.
An embodiment of the invention is described below with reference to the accompanying drawings, in which: Figure I is a front view of a sash window incorporating arrangements according to the invention; and Figure 2 is a sectional view along the line 2-2 of Figure 1.
Referring first top Figure I a sash window includes a frame 10 and two window panels 12,14. A cable 16 is anchored at low level on outer panel at 18 and top level of window main frame at 20. The cable passes over pulleys 22. The anchorage of the cable to the outer panel may be effected through existing brackets but it may be necessary to install brackets.
The friction between the edges of the panels and channels of the frame is sufficient for the panels to stay in any position into which they are slided and as mentioned above, there will be a bottom and top gap which encourages proper circulation of air, as intended by sash windows. If the inner panel is raised half way up the main window frame, outer panel will then close the bottom gap created by inner panel and prevent anybody to clime or fall out of window.
First pulley may be a simple plastic wheel 30 mounted in a shell 32 which is simply attachable in the frame so as not to interfere with the sliding of the panels. Preferably the pulley is located to be hidden from view. Second pulley to be attached to bottom of the inner sliding window panel.
The present invention allows a simple conversion of existing arrangement to an arrangement according to the invention.

CLAIMS.
1. A sash window arrangement including a pair of window panels slidable in a frame and being connected together with a tie whereby movement of one causes a corresponding movement in the opposite direction of the other and being in 2:1 ratio in any relative position of the two panels.
