Abstract: A sash window counterbalance spring mounting arrangement for fitment into a channel section within a window jamb, includes coiled ribbon springs, a spring support mounting including a single integral component for locating and supporting the springs, a support for the springs to support and locate the springs on the mounting, and formed by pairs of triangular cross section projections extend from the rear surface of the main body of the mounting such that when the springs recoil rapidly outer surfaces of adjacent springs contact each other, and including an end portion of the main body which is curved, wing projections extending from the front surface of the main body, and an inter engagement element on the longitudinal end of the mounting for cooperative engagement with cooperative inter engagement features on a sash shoe, and a locating arrangement for locating the mounting within the channel section.

Abstract: A modular spring support mounting for a sash window spring counterbalance arrangement includes at least a first spring support mounting element and a second spring support mounting element each for supporting a respective coil spring. The first spring support mounting element includes a pair of wedged shaped cross section projections. The second spring support mounting element includes an interengagement fitting which engages the pair of wedged shaped cross section projections to in use securely interconnect the first and second spring support mounting elements together. Also a method of installing such a modular spring mounting includes the step of laterally slidingly engaging the spring mounting elements to securely interlock the elements together.

Abstract: A sash window counterbalance spring mounting arrangement for fitment into a channel section within a window jamb. The arrangement comprises at least two coiled ribbon springs, a spring support mounting comprising support means for each of said at least two coiled ribbon springs to support and locate said coiled ribbon springs to the spring support mounting, and locating means adapted, in use, to locate the spring support mounting within and to said channel section. The spring support mounting comprises a single integral component from which the support means depend and from which the at least two springs are located and supported. The support means may comprises sets of pairs of triangular cross section integral projections which extend from the rear surface of the main body portion. An end portion of the main body portion of the support mounting is curved. Wing projections may extend from the front surface of the main body of the spring support mounting.
