The deformable packing assembly comprises a base, and a plurality of elongate deformable fingers which project from the base and upon which the glazing unit is supported. The fingers are arranged in an array on the base and are adapted to, in use, bend. The wedge packing assembly comprises a first wedge element having a base surface and an inclined surface at an angle to the base surface. The first wedge element is adapted to be fitted between the glazing unit and frame along an edge of the glazing unit with the inclined surface inclined at an angle to the normal of the plane of the glazing unit and window assembly. The wedge packing assembly may then further comprise a second wedge element.

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: Window assembly (10) comprises a wedge packing assembly (17) and/or a deformable packing assembly (16) for fitting between a glazing unit (2) and a frame (4) of a window assembly (10) to support the glazing unit (2) within the Frame (4). The deformable packing assembly (16) comprises a base (30), and a plurality of elongate deformable fingers (36) which project from the base (30) and upon which the glazing unit (2) is supported. The fingers (36) are arranged in an array on the base (30) and are adapted to, in use, bend. The wedge packing assembly (17) comprises a first wedge element (20) having a base surface (22) and an inclined surface (24) at an angle to the base surface (22). The first wedge element (20) is adapted to be fitted between the glazing unit and frame along an edge of the glazing unit with the inclined surface inclined at an angle to the normal of the plane of the glazing unit and window assembly. The wedge packing assembly (17) may then further comprise a second wedge element (40).

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 enagagement with cooperative inter engagement features on a sash shoe, and a locating arrangement for locating the mounting within the channel section.

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.

Abstract: A sash window counterbalance arrangement for counterbalancing the weight of a sash window includes a spring support mounting located within a channel in a sash window jamb, a sash shoe slidable in the channel, a spring arrangement which generates a spring force between the mounting and sash shoe to counterbalance the weight of the window, the mounting including at least one mounting peg which projects from the mounting to engage a mounting aperture within one channel wall to locate and secure the mounting within the channel, with the mounting peg being resiliently biased into engagement with the aperture.

Abstract: A sash window counterbalance arrangement for counterbalancing the weight of a sash window. The arrangement comprises a sash window spring support mounting located within a channel in a sash window jamb, and a sash shoe slidable in said channel. In use a spring force is generated between said spring support and sash shoe by a spring means to counterbalance the weight of said sash window. The spring mounting comprises at least one mounting peg which projects from said mounting to engage a mounting aperture defined within one of said channel walls to locate and secure said spring support mounting within the channel. The mounting peg is resiliently biassed into engagement with said aperture.

Abstract: A sash window counterbalance arrangement for counterbalancing the weight of a sash window, includes a sash window jamb with a channel defined within the sash window jamb, the channel having a rear wall and a pair of side walls, a sash window shoe slidable in the channel, a spring arrangement connected at one end to the sash window shoe, and a spring support mounting fitted within the channel to support the spring arrangement, the spring support mounting including a locating peg projecting from the spring support mounting to engage a locating aperture defined within one of the channel walls and locate the spring support mounting along the channel, and a self tapping screw fastener engaging the spring support mounting and one of the channel walls to secure the spring support mounting to and within the channel.

Abstract: A sash window counterbalance arrangement for counterbalancing the weight of a sash window includes a spring support mounting locating within a channel in a sash window jamb, a sash shoe slidable in the channel, a spring arrangement which generates a spring force between the mounting and sash shoe to counterbalance the weight of the window, the mounting including at least one mounting peg which projects from the mounting to engage a mounting aperture within one channel wall to locate and secure the mounting, with the mounting secured and located against slidable movement in a first direction due to the spring force, while movement of the mounting in an opposite direction causes disengagement of the mounting peg from the aperture and the mounting peg includes a lip flange which hooks over a portion of the channel wall adjacent the aperture to secure the mounting within the channel.
