  • Patent number: 6588035
    Abstract: A mattress support system for a bed, comprising a base section, a wire support section, and an upper section. The upper section has one or more substantially rigid edge frame members incorporated therein for increased mattress edge support. The edge frame members may further comprise extensions of the upper section, such that the upper section is wider and/or longer than the base section, so that the mattress support system may be supported by a frame which corresponds to the size of the base section, while fully supporting a mattress which corresponds to the larger size of the upper section.

  • Patent number: 6578213
    Abstract: A nestably stackable assembly for use in a bedding foundation. The assembly has a rectangular border wire with parallel sides and ends. Transversely spaced, parallel and longitudinally extending support wires are connected at their ends to the border wire ends. The support wires are formed so as to be generally corrugated along their lengths with peaks and valleys. The peaks are flattened at their tops, and the flattened tops are generally coplanar with a plane defined by the border wire. The valleys are vertically displaced beneath and intermediate of the flattened tops. Longitudinally spaced and transversely extending, upper connector wires are connected to the sides of border wires, and the upper connector wires are connected along their lengths to the flattened tops of the peaks of the support wires. The valleys have flattened bottoms, and adjacent pairs of the flattened bottoms of the valley are interconnected by resilient connectors.

  • Publication number: 20030070231
    Abstract: The invention relates to a spring pre-assembly for a mattress foundation unit having a wooden base, a plurality of spring units and a mattress supporting wire grid that is supported above the wooden base by the spring units. The spring pre-assembly comprises a plurality of spring units connected to a wire grid consisting of a plurality of grid wire pairs arranged orthogonally to one another. The spring units include a base portion, a pair of divergently extending leg portions and a pair of engagement portions extending in opposite directions from the distal ends of the leg portions. The engagement portions can be engaged with adjacent grid wire pairs, the resulting arrangement being such that the spring units are pre-stressed.

  • Patent number: 6484339
    Abstract: A bedding or seating product comprising a base having a generally rectangular frame and a plurality of internal rails, a wire grid spaced above the base and a plurality of plastic modules connecting the wire frame and the base. Each of the plastic modules has four arms extending upwardly from a bottom portion and terminating in end portions. Each end portion has a pair of perpendicular grooves adapted to receive intersecting wires of the wire grid. The modules are nestably stackable to save space during shipping.

  • Patent number: 6477727
    Abstract: The invention relates to a bearing element having a base plate fitted on a support, for a seat or bed system, with a bearing plate to hold upholstery. The invention seeks to produce a bearing element whose range of spring is approximately equal to the total height, and which is easy to produce. To this end, at least two spring elements serving as bearing arms (12, 22) are fitted between the base plate (11, 21) and the bearing plate (15, 25). These spring elements, configured like leaf springs, are directed outwards from the base plate (11, 21). Their outer ends join the hearing plate (15, 25). In another version of the invention, a spring body (35, 35′) is fitted between the base and bearing plate. The spring body head (35.2) and foot (35.1), like the bearing plate and base plate, have corresponding locking parts, so that the bearing plate can also be removably placed on the spring body (15, 15′) and on the base plate (21).

  • Publication number: 20020112291
    Abstract: A modular sleep system has a foundation unit, an support unit having an innerspring and a support surface covered with a friction material, and a comfort unit having compressible material encapsulated in a woven upholstery material which is engaged by the friction material on the support surface of the support unit to prevent lateral movement or sliding of the comfort unit relative to the support unit, without any fasteners between the support unit and the comfort unit. The comfort unit can be lifted vertically off of the support unit without release or use of any fasteners, to be turned over, fluffed or exchanged for a different comfort unit having different layers of internal materials, feature layers, and support characteristics.

  • Patent number: 6427990
    Abstract: A spring configuration of an individual-segment underspring configuration for furniture including a mattress. The spring configuration is formed of individual spring elements, each containing a supporting plate; a baseplate; a latch holder having latches; and at least one spring body connected between the supporting plate and the baseplate. The spring body has a first center, a second center spaced apart from the first center, a central axis, and cushioning arms disposed in one of a straight plane and a curved plane and extending radially outward in one of a straight manner and a curved manner from the first center and the central axis. The cushioning arms have outer ends with latching devices in a region of the second center, and, in each case in a state in which the cushioning arms are bent over in a manner of a basket in one direction toward the central axis and the second center, the latching devices of the cushioning arms engaging in and securing to the latches of the latch holder.
