    摘要: 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 extending 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.

    摘要: A support device (10) for a hinged panel (12) mounted on a vehicle (14), the panel (12) being angularly displaceable between an opened position (16) and a closed position (20). The support device (10) comprises an elongate connecting member (22) pivotally connected to the panel (12) and an associated rotatable helical mating surface (24). A support arm (26) is pivotally connected to the vehicle (14). The support arm (26), including its own helical mating surface (28) is adapted to telescopingly receive the helical mating surface (24) of the elongate connecting member (22). A multi-coil torsional spring (30) may exert a torque between the respective helical mating surfaces (24, 28) when they are in contiguous relationship. As an operator swings the panel (12) open, the support device (10) extends, and the torsional spring (30) stores potential energy. As the operator lifts the panel (12) to separate the helical mating surfaces (24, 28) momentarily, the torsional spring (30) produces a rotational displacement thereof, thereby re-uniting them. The frictional force generated between the helical mating surfaces (24, 28) resists the weight of the hinged panel (12). The hinged panel (12) may be secured in the opened position (16) or descend toward the closed position (20) at a rate which is controlled by the support device (10).

    摘要: An apparatus for offsetting a constant force over a range of movement, includes a power spring or clock spring, defined by a length of resilient material wound in a spiral, the opposite ends of which are attached relative to one of the force and a fixed point, and to a pulley. The pulley is substantially coaxial with the spring and has a rounded outer contour defining a progressively varying slope proceeding axially along the pulley. A flexible cord wraps around the pulley and leads to the other of the force and the fixed point. The opposite (inner and outer) ends of the spring can be mounted such that the inner end of the spring is fixed relative to the fixed point and the outer end of the spring is attached to the pulley. The constant force can be the weight of a window sash, movable vertically in a frame. The rounded outer contour of the pulley defines a curve corresponding to an increase in torque of the spring with displacement, due to decrease in radius of the spring and decrease in active length of the spring with binding of inner wraps of the spiral.
