  • Patent number: 4886249
    Abstract: A known kind of spring unit, for use in mattresses, seats and the like, is made as an assembly of spring bands which are disposed side by side and a plurality of helical wires (5,6) which extend transversely to the bands and are linked to them. Each spring band comprises a row of springs (1), and each pair of adjacent springs is integrally connected by a connector (2) which includes two spaced end portions (3), which are transverse to the band and are embraced by helical wires. Variations in manufacture lead to variations in the spacing between the end portions. The invention provides for the further bending of each connector (2), after initial formation of the spring band, to cause the end portions to take up a predetermined spacing. This is effected by reshaping corner portions of the connector between dies (31,42) so that the corner portions (8) are finally of more gentle curvature than they were (12) when initially formed.

A plurality of coiled spring wires extend transversely of the rows while interconnecting adjacent coil springs in each row and adjacent coil springs of adjacent rows by being wound about the coil springs. The coiled spring wires are located on opposite sides of the core. On only one side of the core which forms the sleep surface are a plurality of transversely extending "torsion" spring wires, however, these wires are of a generally rectilinear shape with intermediate offset portions at intervals extending generally along the head to foot direction while being connected to the coil springs of each of the rows. The offset portions provide torsion arms providing torsional resistance to deflection at the sleep surface to thereby increase resistance to deflection while, at the same time, distributing loads across the sleep surface.

  • Patent number: 4726572
    Abstract: A spring coil has an open-ended terminal convolution which is connected to the body of the coil through a gradient arm. The gradient arm can be readily varied in length in manufacture to alter the compression and thereby the firmness of the spring coil. Offset portions are advantageously formed on terminal convolutions with a major straight part which is outwardly spaced from minor straight parts. This provides a three point engagement for the offset portion when connected to a border wire with a border wire helical spring. The offset portions of the spring coils have inside and outside shoulders adjacent their ends. The pitch of cross-helicals which join overlapped offset portions is chosen so that a cross-helical simultaneously engages the outside shoulders of one of a pair of overlapped offset portions to firmly hold the spring coil against rotation. The cross-helical preferably also catches the inside shoulders of the other overlapped portion to additionally hold that spring coil against rotation.
