ABSTRACT:
A window balance biasing device including an outer tubular member telescopically receiving an inner tubular member. The inner tubular member and the outer tubular member are movable relative to one another to adjust the axial length of the window balance device. A pair of spring biased detents are supported within the inner tubular member and the spring biased detents are engageable with a desired pair of apertures provided in the outer tubular member to facilitate a locking engagement therebetween and thereby facilitate locking of the inner tubular member and the outer tubular member at a desired axial length. The free ends of both the inner and outer tubular members support a window balance engagement member. During use, the window balance biasing device is adjusted to an axial length which is slightly longer than the spacing between a pair of opposed balance such that when the window balancing device is forced into a substantially horizontal position, the pair of opposed window balances are biased away from one another to facilitate pivoting of the window from an in use substantially vertical orientation to a substantially horizontal cleaning orientation and vice versa once the cleaning operation is complete. In a preferred form, at least one of the window engagement balancing members is slidably engageable with one of window balances.
