Definitions

  • the present invention generally relates to a mattress support for being interposed between an underlying box spring and overlying mattress, and more specifically to a portable under mattress support uniquely constructed to incorporate spaced-apart resilient slats interconnected by strips, for use to restore the support integrity to one or more sagging or otherwise softer well-used areas of a mattress.
  • Some devices include foldable cardboard pieces, and some devices sit atop a mattress and are made of steel rods or other hard and rigid materials, which do not provide a comfortable support for at least the foregoing reasons.
  • Other approaches have attempted to provide a less rigid under mattress structure intended to be inserted between a box spring and mattress immediately prior to initial use of the bed, in lieu of more rigid sheets and slats, for the purpose of providing the firm support of, for example, a plywood sheet, yet with controlled yieldability in order to give the desired degree of firmness for supporting a reclining body.
  • bed board structures e.g., U.S. Patent No. 2,847,685 to Freedlander
  • the support incorporates numerous features that render it useless for the intended purpose of the present under mattress support, including the incorporation of rigid slats running longitudinally (i.e., from the top end to the bottom end of the bed).
  • the slats must be constructed of wood, steel, rattan, plastic, aluminum or some other rigid material in order to provide a relatively level base for the overlying mattress without permitting enough sag in the longitudinal direction to throw the occupant's back out of line.
  • the design of the hinges, the spacing that the hinges create between adjacent panels, and the relative gap created by the hinges vis-a-vis the size of the adjoined panels must be such that they enable adjacent panels to be precisely stacked upon one another to increase the height for converting the apparatus from a flat mat to a stacked step or bench.
  • the required structure hinders the ability to roll up the panels into a rolled form for packaging, storage and the like.
  • the structure of the hinges is specifically designed to prevent displacement of adjacent hinges with respect to one another and, therefore, prevent freedom of movement of adjoined panels with respect to one another. Therefore, the '001 patent and similar structures specifically prevent displacement of adjacent panels (i.e., preventing any degree of freedom to move toward or away from one another) which is a crucial feature of the under mattress support of the present invention.
  • the problem being addressed herein is not one of providing an orthopedic or other medical-related solution for people with extreme back issues by over- supporting or hardening the mattress surface.
  • the invention described herein is specifically designed, configured and adapted to enhance existing softer and sagging regions of a well-used mattress so that the mattress continues to provide comfort and support for typical individuals while sleeping, and at the same time extends the useful life of the current mattress by restoring the mattress to its original shape and comfort.
  • the use and wear of any mattress can be extended to continue to provide comfort and support for one or more individuals while sleeping, and reducing the expense associated with purchasing a replacement mattress due to sagging or concave pockets and deformities due to extended use.
  • the under mattress support described herein is positioned under a mattress and on top of its accompanying box spring or similar mattress support. That is, the under mattress is positioned interposed between the box spring and mattress. Furthermore, the under mattress support of the present invention is constructed to provide the flexibility to either stack the slat (or encased slat) portions or to roll up the apparatus to facilitate packaging options for sale and storage.
  • an under mattress support for extending the use of a sagging mattress, the under mattress support functions to raise the height of a sagging or soft area or region of a mattress to restore it to its original configuration.
  • an under mattress support is provided for positioning between a box spring support and a sagging area of an overlying mattress, the box spring support and overlying mattress having corresponding sides extending longitudinally between upper and lower ends of the respective box spring and mattress ends.
  • the under mattress support includes: (a) a series of parallel spaced-apart laterally extending elongated resilient unitary slats, each slat having a predetermined width and height and a predetermined slat length adequate to extend laterally from a portion of one of the sides of the mattress to a portion of the opposite side of the mattress; (b) a unitary bottom pliable fabric cover disposed beneath the slats such that the bottom pliable fabric cover extends completely beneath all of the slats; and (c) a top pliable fabric cover disposed above the slats such that the top pliable fabric cover extends completely above all of said slats, the top pliable fabric cover selectively fixedly attached to said bottom pliable fabric cover in a manner resulting in the permanent encasement of each of said resilient slats within a corresponding unique slat enclosure such that each individual encased slat has a contiguous exterior surface completely surrounded by,
  • each unitary resilient slat is completely permanently encased within a corresponding unique enclosure rendering the slat inaccessible.
  • the selective attachment further includes first and second laterally- extending linear cover attachment portions each permanently affixing the top and bottom fabric covers to one another along the length of the respective attachment portion, the cover attachment portions disposed in a predetermined desired spaced-apart relationship to one another within an area between adjacently positioned first and second enclosed slats having opposing corresponding first and second slat lateral sides, a first one of the attachment portions running adjacent to the first slat lateral side, and a second one of the attachment portions running adjacent to the second slat lateral side to form a pliable fabric strip having a strip width of at least approximately one inch and having a fabric strip length equal to a corresponding length of each slat enclosure as measured from the opposite edges of adjoined top and bottom pliable fabric covers enclosing opposite ends of each resilient slat, such that opposite ends
  • an under mattress support periphery is created that is defined by linear edges, wherein the formed pliable fabric strips enable and facilitate lateral compression of the under mattress support when the under mattress support is in use supporting the mattress, each of the formed pliable fabric strips having adequate resiliency to enable selective rolling of the under mattress support longitudinally along the respective lengths of the pliable fabric strips to enable the under mattress support to be easily rolled up into a compact configuration, thereby facilitating compact packaging of the under mattress support prior to initial use, and subsequent compact storage of the under mattress support when not in use.
  • each pliable fabric strip separating each pair of adjacent enclosed resilient slats has a strip width adequate to maintain a minimum spacing between the adjacent enclosed slats within a range of approximately 2 inches to 5 inches.

Abstract

L'invention concerne un support inférieur de matelas qui prolonge la longévité d'un matelas existant qui peut comprendre des zones concaves entraînant un affaissement ou des zones molles, comprenant une pluralité d'éléments en forme de lattes parallèles, espacées, élastiques et allongées, raccordées les uns aux autres par des bandes souples de façon à former un réseau de lattes parallèles. L'espacement des bandes souples des lattes élastiques parallèles permet une compression latérale afin d'améliorer le support. En cours d'utilisation, le support inférieur de matelas est intercalé entre un matelas et un sommier à ressorts sous-jacent de sorte que les lattes allongées s'étendent le long de leur direction longitudinale d'une partie d'un côté du matelas au côté opposé du matelas où la partie concave d'un matelas affaissé ou mou apparaît dans le cadre d'une utilisation normale.
