Description

2338979 ADJUSTING DEVICE FOR A SINGLE-HUNG SASH ASSEMBLY.
DESCRIPTION OF PRIOR ART.
Traditional wooden frame vertical sliding sash window in general compromise a pair of sliding window panels, each having a counterweight acting over a pulley. This arrangement is not very successful, particularly in coastal areas due to corrosion of counterweights and this often results in the panels becoming very difficult to slide. Another problem is the failure of the cord with result that the panels do not stay in the 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 avoids or at least minimises the difficulties referred to above.
SUNWARY OF THE INVENTION.
The object of the present invention is to provide a device allowing a single-hung sash assembly to be easily adjusted by anyone, including a person unskilfid in the art of sash adjustment. Another object of the invention is to provide a device that is inexpensive to manufacture, reliable and easy to install. Also eliminate use of the counterweights to balance the window panels. Advantages of the invention relates to an improvement in a single-hung sash assembly of the type comprising: Two adjusting devices, each fitted to the centre of the bottom part of inner section of window main frame. One end of the connecting cable on each side of the frame is attached to outer window panel, thereafter is sling over first existing pulley in the top of the widow main frame, down inside of the window casing, true adjusting device pulley, up to the top of the window casing, true second existing pulley, out of the window casing and is then attached to the inner window panel. Correct position of the window panels is than adjusted by means of turning the adjusting device tension screw clockwise. By turning the tension screw anticlockwise will result in loosening of connecting cable.

EIVBODRvENT OF THE R4WNTION.
An embodiment of the invention is described below with reference to the accompanying in which:
Figure I is a front view of sash window incorporating the arrangement according to the invention.
Figure 2 is a sectional view of Figure 1.
Figure 3 is a sectional view of the adjusting devise.
Figure 4 is a top view of the adjusting device.
Referring first top Figure I a conventional sash window includes a frame 10 and two window panels 11. A cable 19 is attached at points 14, cable passes over pulley 13 down and true the adjusting device 12, up over pulley 13 and is attached at point 14.
With reference to Figure 2 is a sectional view of the main fi-ame 10 which shows position of the adjusting device 12 with relation to position of existing main frame pulleys 13 and running of the cable 19.
Sectional view of the adjusting device as shown in Figure 3 comprise of a bracket 18, whereby pulley 17 is approximately 50 mm or large diameter, made of stainless steel or other wear resistance alloy. The pulley 17 is attached to 10 mm diameter screw 16 and by turning the nut 15 clockwise the pressure is applied on cable 19. By this movement window panels I I are placed in the required position. By turning nut 15 anti-clockwise direction, pressure on connecting cable 19 is released and cables at point 14 can be detached from window panels 11.
Mounting bracket 18, position of the pulley 17 and adjusting screw 16,15 is shown on on Figure 4.
The present invention allows a simple conversion of an existing arrangement to an arrangement according to the invention.

Claims (5)

CLAIMS.
1. A sash window arrangement including a pair of window panels slidable in a frame and being connected together with tie whereby movement of one causes a corresponding movement in the opposite direction of the other, two adjusting units being substantially aligned with existing pulleys in the top part of the window main fi-ame and to adjust the window panels to required position.
2. The arrangement as claimed in claim I in which adjusting units operate over direction clockwise to tighten the connecting cables and anticlockwise to release the tension.
3. The arrangement as claimed in claim 2 in which adjusting unit pulley is moved in to position by turning adjustment screw over the mounting bracket.
4. A sash window adjusting unit arrangement as substantially described with reference to the accompanying drawings.
5. An arrangement as claimed in claim I substantially as described herein with reference to the accompanying drawings.
