ADJUSTABLE HINGE
FIELD OF THE INVENTION
The present invention relates to casement hinges for windows and more particularly towards improved track pivots of casement hinges.
BACKGROUND OF THE INVENTION
The casement window has a window sash moveably mounted within a frame by a pair of hinges mounted between the window frame and the top of the window sash. It is typical that such a hinge has a track moveable relative to the window and a sash arm connectable thereto. A support arm extends between the sash and the sash arm.
The support arm interconnects the track and the sash arm, with the support arm being pivotably connected to the sash arm and to the track. The sash arm is, in turn, pivotably connected to a mounting shoe which is supported and guided for movement lengthwise of the track.
A variation of the hinge includes an intervening link between the sash arm and the moveable shoe to provide for an offset sash arm. Such hinge typically include a separate intervening link between the support arm and the moveable shoe to provide further support.
When window hinges of the above type are installed, proper operation and sealing of the window requires that the fixed track pivot, which is usually between the support arm and the window frame, be properly located relative to the window sash.
Over the life of the window, the proper location of the fixed track pivot may change to slight shifting of the window, window frame, etc. resulting in a sag in the sash. Sash sag is a condition formed when the sash and the frame of the window are not longer square to each other when in the closed position, or the edge of the sash which is opposite the hinges seems to sag in comparison to the frame of the window. As a result, the window may not seal tightly or even open and close properly.
A solution to the above has usually required that the hinge track be provided with slotted holes and the hinge mounting screws in the slotted holes be removed to allow for shiffting of the track. However, repeated removal of the screws can result in gradual loosening of the strength of the mounting. Furthermore, settling of the frame to properly position the window sash can necessitate that the window be first opened to allow access to the hinge for adjustment and then closed to check for sash alignment.
It has been proposed in the art to provide for a connection for adjustable holdings two window hardware members together. Such an arrangement is shown in U.S. Re-Issue Patent 35,635. In this arrangement, there is provided a pivot adjustment for the connection between the sash support arm and the track which includes a eccentric shaft to thereby provide means for adjusting the connection.
The means for adjusting the connection require the use of a wrench. This reference also does not teach the ability to adjust the connection between the sash support arm and the sash arm.
SUMMARY OF TIIE INVENTION
It is an object of the present invention to provide a simple and easily adjustable connection between the sash and sash support arm.
According to one aspect of the present invention, there is provided an improvement in a hinge assembly suitable for use in a casement window wherein the hinge assembly includes a track, a sash arm having a first sash arm end connected to the
