Transverse Collapse Patents (Class 5/116)
  • Publication number: 20140345047
    Abstract: A collapsible mattress support for a box spring includes hinges on opposite sides of a middle cross bar. First and second side bars are pivotally attached to one hinge, and third and fourth side bars are pivotally attached to the other hinge. Each of the bars rotates about parallel axes that are orthogonal to the hinges. The four side bars each has a common width. A first distance between the axes about which the first and second bars rotate equals twice the common width of the bars plus a second distance between the axes about which the third and fourth bars rotate. In one embodiment, the cross bars are extendable. The components of the mattress support for Queen, California King and Eastern King sized mattresses fit in a packing box whose length is no greater than 45 inches and whose width and height are each no more than 7 inches.

    Abstract: A portable, reversibly-extensible hammock has a foldable structure for supporting a substantially planar support surface. The hammock can be folded for transportation or storage, and can be shifted to an extended configuration to create a rectangular structure similar to a cot or hammock frame. A dual-purpose tensioning strap joins the support surface to the foldable structure and increases the structural integrity of the structure by urging top portions of leg members toward a center point of the rectangular structure.

    Abstract: A foldable bed having a frame and a cover attached to the frame. The frame has two handles, two identical side beams each having a pair of groove beams pivotally connected to one of the handles, connectors and bars pivotally connected to the handles or the connectors. The foldable bed is able to be folded by a simple action of pulling the handle upward meanwhile stepping on the peddling member. And it is able to be expanded by a simple action of breaking off the two groove beams with two hands of a user. Furthermore, the foldable bed occupies relatively small storing space when folded since a width of the folded bed is much shorter than that of the expanded one's.

  • Patent number: 4801176
    Abstract: A completely collapsible chaise-cot deriving an unique compact folding characteristic from a folding transverse foot-base support structure. The folding support structure gives an increased compactable collapsibility to this invention over the folding chairs and cots of prior inventions. Earlier art, although achieving a modicum of collapsibility for cots, lawn chairs and the like, was devoid of full and compact collapsibility because no provisions had been made by the inventors to fold the common transverse base and upper frame supporting structures. The long felt need, therefore, for a folding, completely collapsible transverse foot-base support structure has been fulfilled by this invention and the art form has achieved a new level of utility as a result.
