Definitions

  • a composite bed cover comprising an outer wrapper which includes two spaced layers of textile material. An insert is received between these layers and comprises a fibrous inner layer and two continuous outer layers of foamed plastic sheet material. The outer layers of sheet material are respectively contiguous with the major surface of the inner layer. At least some adjoining layers are interconnected by suitable means and'major areas of each layer are permitted freedom of movement with reference to the adjacent layers.
  • the present invention relates to a cover. More particularly the invention relates to a bed cover. Still more specifically, the invention relates to a composite bed cover which has been found to be particularly suitable for use in hospitals and similar institutions.
  • FIG. 1 is a perspective view, partly sectioned, of a bed cover in accordance with the present invention
  • FIG. 2 is a sectional elevation taken on the line IIII of FIG. 1; and FIG. 3 is a view similar to FIG. 2, but illustrating yet another embodiment.
  • FIG. 1 the blanket or bed cover shown there comprises five layers hereafter with reference to the embodiment in the drawing.
  • the inventive cover includes a pair of spaced layers 1, 5 of textile material. Received between these layers is an insert which comprises in the exemplary embodiment a layer 3 of a fibrous filler material sandwiched between two layers 2, 4 of foamed plastic material.
  • the various layers are connected to one another in such a way that major areas of each layer retain freedom of movement with reference to the adjacent layers.
  • the outer layers, 1, 5 constituting the wrapper may be of any textile material generally suitable for the manufacture of blankets. Such textile material may be of natural or synthetic fibers and may be in various different weaves.
  • any plastic material which can be foamed will be suitable. This encompasses plastic materials which in their foamed state are open-celled, as well as those which are closed-celled. It can also include foamed plastic materials which are impervious to the passage of air therethrough.
  • each of the layers 2, 4 may be constructed by stacking a plurality of sheets of foamed plastic material having different characteristics, such as a sheet of open-celled material backed by a sheet of closed-celled material.
  • a major consideration in the layer 3 may consist of a mass of natural or synthetic fibers, and such fibers may be matted together so as to be loosely coherent. Increased coherence may be imparted to the layer 3 by cross-stitching, felting, or pneumatic matting.
  • the layer 3 will be further stabilized on one or both of its major surfaces by a chemical treatment, such as spraying with a liquid plastic which will solidify but remain pliable, or by dusting with a suitable agent whereafter the layer can be heated until the thus-deposited agent will first become fluid and then reset so as to help bind the individual fibers together. See in this connection the illustration at the interface between the layers 2-3 and 2-4 in FIG. 3.
  • a chemical treatment such as spraying with a liquid plastic which will solidify but remain pliable, or by dusting with a suitable agent whereafter the layer can be heated until the thus-deposited agent will first become fluid and then reset so as to help bind the individual fibers together.
  • each of the layers may vary widely. Purely as an example, but in no way limiting, the layers 2, 4 may for instance be of a thickness on the order of 1.5 millimeters. Also, no two layers need be of identical thickness.
  • the layers 1, which constitute the outer wrapper can be provided in individual superposed layers or in the form of a tube (see FIG. 3) into which the insert comprising the layers 2, 3, 4 can be placed.
  • the layers 1, 5 may be provided in other manner, for instance in form perhaps of a box-shape wherein the layers 1, 5 are joined by panels or strips 6 which are secured to their circumferential edge portions.
  • the cover is comprised of individual layers, that is that the layers 1, 5 are not inherently joined together at their circumferential edge portions, then the layers 1-5 can be joined by seaming along their circumferential edge portions. No further joining will be necessary inwardly of the edge portions.
  • the edge portions need not be joined and the layers can be secured together by means of rows of stitches which extend in one major direction of the layers and widely spaced from one another. Such spacing may be on the order of 22-30 cm., although these figures are merely given as a general indication and are not restrictive. Of course, similar rows of stitches can also extend transversely of the first rows and will again be widely spaced from one another.
  • the layers can also be held to one another by individual stitches or groups of individual stitches which are widely spaced from one another.
  • the stitching can be replaced by the application of adhesive means in rows, that is in a manner similar to the stitching, or, if the materials used do so permit, by heat-welding of the materials along lines corresponding to the above-mentioned stitching or at predetermined points.
  • the dashed lines in FIG. 1 are intended to be representative of all of these possibilities.
  • Yet a further possibility would be only to scam directly adjoining layers to one another, in that for instance layers 1 and 2 are joined, layers 2, 3 are joined but at a point spaced from the location at which layers 1 and 2 are joined, and so on. This is illustrated in FIG. 2.
  • the interconnection of the layers must be such that for each layer, or at least major areas thereof, freedom of movement with reference tothe layers adjacent to it is preserved.
  • the insert comprising layers 2, 3 and 4 need not be secured at all to the layers 1 and 5 but can be received within the tube with freedom of movement relative thereto, as shown in FIG. 3.
  • At least some of the surfaces, for example the outwardly directed ones, of the layers 1 and 5 will be roughed to provide a pleasant hand.
  • a composite bed cover particularly for use in loosely coherent fibers and two continuous outer layers.
  • a bed cover as defined in claim 1 wherein said insert comprises additional layers of foamed plastic material and of fibrous material, such layers being alternated so that a layer of fibrous material is surrounded by two layers of foamed plastic material, the latter always constituting the outermost layers of the insert.
  • a bed cover as defined'in claim 1, wherein said means interconnecting said layers defines seams joining said layers along circumferential edge portions thereof.
  • a bed cover as defined in claim 1, wherein said means interconnecting said layers defines seams joining said layers in the direction of at least one major extension thereof, the respective seams being spaced transversely of said one extension.
  • each of said layers of foamed plastic material comprises a plurality of stacked sheets of foamed plastic material.
  • a bed cover as defined in claim 1 and further com means interconnects said'layers at a plurality of spaced-' apart positions.
  • said means comprises thread means.
