Of Slats And Springs Patents (Class 5/239)
  • Patent number: 9351585
    Abstract: A slatted bed frame having a plurality of upper and lower slats arranged transversely to a longitudinal axis of the bed frame, each slat being held at both ends by an elastic slat support and being spaced from the other slats, each of the slats forming a horizontal plane, with the upper slat plane forming a lying surface for a mattress pad, the lying surface being interrupted by a partial removal of at least one upper slat thereby forming at least one recess in the lying surface, into which at least one elastic insertion element, which forms a part of the lying surface, is arranged. In the region of the recess, a hanging insert is inserted, which is held at a distance from the lower slats.

  • Patent number: 8418284
    Abstract: A base for bed mattress having a plurality of transverse slats, with each slat end attached to the frame of the base and pivotally connected to first end of a rod at the center of each slat is provided. The rod is attached at its second end to a dynamic pulley. The dynamic pulleys are connected by a common cord or flexible attachment running over stationary pulleys mounted between the slats to a central beam attached to the frame of the base. Improved distribution of human body support can thus be achieved independent of the contour and weight of the body at any sleeping position. Springiness of the base can be modified by changing the elasticity of the flexible attachment. The dynamic support base reduces the need for thickness of the mattress and of the bed pillow.

    Abstract: A bed with a flexible supporting spring system without a frame. The flexible supporting spring system is supported by a supporting frame or directly by the bedstead. The flexible supporting spring system can be rolled and therefore can easily be transported. Above all, however, the flexible supporting spring system can be used for different beds and can be adapted individually to different sleeping cultures.

  • 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).

  • Patent number: 5557813
    Abstract: A knock down mattress system comprises a generally rectangular box-like shell having a bottom panel, a top panel and side panels interposed therebetween. A plurality of generally elongate bolsters are dimensioned and configured to be positioned within the shell in abutment with the side panels thereof. Each bolster comprises a casing containing resiliently compressible, pocketed coil springs, thereby providing a firm but compliant perimeter around the bed. The bolsters are maintained in proper position within the shell by straps which cooperate with loops formed in the bottom panel of the shell. By this configuration, the bolsters define an interior bounded space within the shell to contain a water mattress, an air mattress or other suitable mattress member. Because the bed system comprises an assembly of discrete pieces, it can be shipped conveniently to the customer in disassembled form and is readily assembled at final destination.

  • Patent number: 5495629
    Abstract: The support grid for a lying, reclining or sitting furniture, particularly for a bed, according to the present invention comprises a plurality of support elements (1), e.g., laths, and at least two spring bodies (2), the latter being positioned transversely to the laths, the laths rest on the spring bodies and are fastened thereto. The laths have in cross-section a curved support under surface and are so fixed to the spring bodies that they can be pivoted to a limited extent with respect to the spring bodies about an axis running parallel to the longitudinal lath axis. As a result of this pivoting possibility each lath is given a further degree of freedom making it possible for it to adapt further to the shape of a body resting on the lath grid than is possible through the elasticity of the spring body. This increases the lying of sitting comfort of the support grid according to the invention.

  • Patent number: 4181991
    Abstract: An improved mattress foundation particularly suited for use with foam mattresses to provide proper support for the mattress and to duplicate the feel of box springs. The mattress foundation utilizes an upper and lower frame assembly separated by a flexible, resilient material, which may be in the form of blocks, strips or slabs of flexible, resilient material, with the upper frame assembly preferably being somewhat flexible so as to be capable of deforming from its normal planar condition when subjected to more concentrated loads. The material separating the upper and lower frame assemblies are selected to have a resilience which will support the weight of one or two persons while distributed over the mattress foundation without substantial deflection, but which will deflect significantly when subjected to an individual's weight in more concentrated form, such as occurs when an individual sits on the edge of a bed or is getting into or out of the bed.
