  • Patent number: 9138801
    Abstract: Disclosed herein is a method of making a spring core (12) for a bedding or seating product (10). The spring core (12) has coil springs (26) having unknotted end turns (72, 74) made from high tensile strength wire. In each embodiment, the end turns (72, 74) of the coil springs (26) are generally U-shaped having one arcuate leg (76) longer than the other (78), the legs (76, 78) being joined by a connector (80) having an arcuate bump (81) therein. The springs (26) are oriented in the spring core (12) such that a long leg (76) of one end turn (72) abuts a short leg (78) of the adjacent end turn (72) prior to being wrapped in helical lacing wire (32). The high tensile wire enables the coil springs (26) to be manufactured using less wire than heretofore possible.

  • Patent number: 6050553
    Abstract: A device for connecting springs together to define a support surface includes four arms each which extend in an outward radial direction from a center of the connecting device, the length of each arm defined by two sides extending in spaced relation to one another. Each arm includes a stiffening portion extending in a widthwise direction between the sides of the arm and extending from an end thereof towards the center of the connecting device only partially along the length of the arm. The straight sides of each arm have identical height dimensions and the stiffening portion has a lesser height than the height of the sides. The sides and the stiffening porting of each arm together define a planar surface of the arm and a finger portion extends from the end of the arm to define with the planar surface a U-shaped recess for gripping a top coil of a coil spring.

  • Patent number: 5699999
    Abstract: A mattress inner spring core comprising a plurality of coil springs arranged in longitudinally extending columns and transversely extending rows. Each coil spring has an identically configured upper and lower end turn between which are a plurality of central convolutions defining a spring axis. Each end turn comprises first and second offset legs connected by a linear base web. A portion of a first leg of one end turn overlaps a portion of a second leg of an adjacent end turn in an overlapping region. Helical lacing wires encircle the legs of adjacent end turns to connect rows of springs. Each helical lacing wire has multiple revolutions encircling the overlapped legs of adjacent end turns with the same number of revolutions of the lacing wire encircling the overlapped portions of the legs and at least one complete revolution encircling a non-overlapped portion of the first and second legs of the end turns.

  • Patent number: 5669087
    Abstract: A mattress spring core having a plurality of zones of differing firmnesses due to different characteristics of helical lacing connectors within the particular zones. The spring core has a plurality of identical coil springs arranged in side-by-side transversely extending rows and columns. The coil springs are connected together at the upper and lower ends of the springs with helical lacing connectors which encircle a portion of the upper and lower faces of the springs. The helical lacing connectors may be of a heavier gauge wire in one or more zones of the mattress spring core thus causing that particular zone to be of an increased firmness relative to the other zones of the mattress. Alternatively, the helical lacing connectors within a zone may comprise two or more co-axial lacing wires to impart greater strength or rigidity to one or more zones of the mattress.

  • Patent number: 5584083
    Abstract: A spring core for a mattress consisting of a plurality of side-by-side rows of identically configured helical coil springs each made of a single piece of wire having a central portion of a first radius defining a central spring axis and terminating at opposing ends with unknotted upper and lower end turns disposed in planes substantially perpendicular to the spring axis. The springs are connected with each other at their upper and lower turns by connecting lacing wires. The upper and lower turns are each substantially U-shaped, having a longer relatively straight leg and a shorter arcuate leg located at the free end of each end turn, the legs connected to each other by a base web. The radius of the shorter arcuate leg is substantially less than the first radius of the central portion of each coil spring. All the coil springs are oriented in the same direction, except along an edge region of the spring core.

  • Patent number: 5575460
    Abstract: Described is a spring core for a mattress, consisting of a multiplicity of identically shaped spiral springs with in each case two end rings lying diametrically opposite each other, which change to a spring coil part arranged centered between them, whereby the end rings are shaped approximately circular and consist essentially of two assembly legs, one transition leg and one additional leg and are opened on one side, whereby the leg lying opposite the respective open side of the upper or lower end ring is bent radially outward with respect to the longitudinal axis of the spring.

  • Patent number: 5558314
    Abstract: A support device having a plurality of support units, each comprising a plurality of flexible, substantially vertical support columns, with the bottoms of the support columns attached at equidistant intervals to a base member and the tops of the support columns attached at equidistant intervals to a substantially perpendicular support platform. The support columns provide directional flexibility to the columns, upon compression, to provide a substantially uniform counter-force through a range of flexion of the support columns and corresponding downward deflection of said support device. Such uniform counter-force during compression simulates a fluid-like support system. The support columns may be comprised of a solid, synthetic foam such as high density polyurethane or springs made of metal or other material. The support units preferably are arranged in a matrix to provide collective support.

  • Patent number: 5098124
    Abstract: Padding for use on vehicle doors for protection of occupants in side impact accidents is composed of a plurality of cells. Each cell is filled with air and sealed except for an orifice. The flow of the air through the orifice provides the damping required to absorb the energy of the impacting occupant. Each cell contains a spring, usually in the form of foam rubber, to maintain the cell in its inflated shape. The plurality of cells provides for better control over the motion of the occupant. The padding can also be used on any surface of the passenger compartment including knee bolsters, headrests, A and B pillars, roofs structures, roof and seats.
