-1- 2416180 Sash Window Frame
Description
The present invention relates to a method of making a sash window frame and a sash window frame.
Sash windows are well known in the art. Conventional sash window frames comprise pulley heads, left and right pulley stiles, sills and inner and outer liners.
In a conventional method of constructing a sash window frame, the ends of the pulley head are attached to the left and right pulley stiles respectively. Typically, this Is achieved by means of a housing joint, each pulley stile being trenched at its upper end so as to receive one of the ends of the pulley head. The pulley stiles are glued onto the pulley head and then nailed in place to further secure the joint.
Next, the lower ends of the pulley stiles are located within respective asymmetric channels, which are cut into the upper surface of the sill at opposite ends thereof.
The left and right pulley stiles are secured within the asymmetric channels by means of a pair of wedges, one of which is inserted into each of the asymmetric channels, adjacent to the end of each pulley stile, so as to prevent the end of the pulley stile from moving relative to the sill.
Once the basic frame has been assembled, inner and outer liners are added to each of the pulley stiles and the pulley head. The liners are glued onto the basic frame and then nailed in place so as to create a cavity in which the pulleys and cords of the sash can be housed. There is a problem with this method, however, in that it is undesirably time consuming.
According to the present invention, there is provided a method of making a sash window frame, the method comprising constructing first and second jamb units and a head unit and fixing one of said jamb units to each end of said head unit, wherein each unit comprises inner and outer liners attached to an elongate member. - 2
Preferably, the method comprises fixing the head unit to a jamb units by providing a butt joint held by separate fastening means.
Preferably, the method comprises using a CNC machine to shape the ends of the s head unit to conform to the complimentary parts of the jamb units.
Preferably, said separated fastening means comprises dowels or threaded fastening means.
Preferably, the method comprises using dowel to locate the inner and outer liners of the head unit to locate relative to the inner and outer liners of a jamb unit, respectively.
According to the present invention, there is provided, a sash window frame comprising first and second jamb units and a head unit, wherein each unit comprises inner and outer liners attached to an elongate member and the head unit is mounted between the jamb units by means of butt joints secured by separate fastening means.
Preferably, the ends of the head unit are shaped so as to conform to the complimentary parts of the jamb units by means of a CNC machine.
Preferably, said separate fastening means comprises dowels or threaded fastening means.
Preferably, the inner and outer liners of the head unit comprise dowel for locating said liners relative to the inner and outer liners of a jamb unit, respectively.
An embodiment of the present invention will now be described, by way of example, with reference to the accompanying drawings, in which: Figure 1 is a schematic view of a window frame according to the present invention; Figure 2 is a perspective view of the right hand end of the head of the window frame of Figure 1; - 3 Figure 3 is a perspective view of the upper end of the right hand jamb of the window frame of Figure 1; . Figure 4 is a perspective view of the right hand end of the sill of the window frame of Figure 1; s Figure 5 is a perspective view of the lower end of the right hand jamb of the window frame of Figure 1; Figure 6 is a sectional view of the window frame of Figure 1 along the line X-X.
