Definitions

  • the invention relates to a mattress cover that comprises an upper face (top face) and a lower face (bottom face) and is intended to receive a mattress core.
  • Mattress covers that are generally known in practice are usually intended to tightly encase a rectangular mattress core, the upper face and lower face of which have a length and a width that are large compared with the height and form a lying surface for a person.
  • the mattress cover generally consists of a fabric region that forms the upper face and a fabric region that forms the lower face.
  • a fastener for example in the form of a zip fastener, is provided for this purpose, which fastener extends at least in part on the longitudinal sides and on the transverse sides when put onto the mattress core.
  • the fabric regions of the upper face and lower face may be formed by individual fabric panels that form the relevant lying surface or the lower face and which are interconnected by fabric strips that form longitudinal sides and the transverse sides. Fabric strips of this kind are generally connected to the fabric panels of the upper face and lower face by means of stitched seams, it being possible for the stitched seams to be covered by an edge binding or a welting band.
  • Ventil strips consisting of a material that is highly permeable compared with the further mattress cover fabric are in addition often used on the longitudinal sides and transverse sides, since usual cover fabrics for a mattress cover usually have a low degree of air permeability and the mattress core is otherwise inadequately ventilated.
  • DE 20 2012 005 880 U1 furthermore discloses designing a mattress cover in two parts, such that one side is formed of a viscoelastic foam, as a winter cover, and the other side is formed of warp-knitted 3D spacer fabrics, as a summer cover which, on account of the greater breathability thereof, produces a better microclimate for the sleeper.
  • weft-knitted spacer fabrics are more stretchable than warp-knitted spacer fabrics, with the result that a mattress cover formed having a weft-knitted spacer fabric makes it possible, in principle, to increase the comfort for a user, since said mattress cover can be formed so as to be soft, springy and to have a pleasant feel.
  • An object of the present invention may therefore be to provide for a mattress cover of the type mentioned at the outset, which cover is particularly breathable, forms a comfortable and soft lying surface, and allows for simple workability.
  • a mattress cover comprising a cover fabric that forms an upper face and/or a lower face that are each dimensioned as a lying surface for a user, in that the cover fabric is formed having a weft-knitted 3D (three-dimensional) spacer fabric at least on the outer face thereof and comprises a honeycombed mesh structure having outwardly open recesses on the outer face thereof.
  • the invention therefore makes use of the advantages of a weft-knitted spacer fabric which typically comprises a spacer structure having stitches of knitted monofilament or multifilament threads, and combines said advantages with the advantages of a honeycombed mesh structure that allows particularly efficient air circulation and moisture removal from the mattress.
  • the honeycombed, outwardly open recesses are advantageous not only with respect to air exchange and moisture removal as well as compensation of temperature fluctuations in general, but also allow for increased springiness which provides a user with a soft feel and in addition allows the mattress cover to be optimally adapted to the user lying thereon without said user being disturbed in the process by coarse spacing threads that are often noticeable in weft-knitted spacer fabrics.
  • a mattress cover of this kind can be produced in a simple manner, for example on a large circular knitting machine operating in accordance with a 3-way technique, at a high throughput over time and thus very economically.
  • the recesses of the mesh structure are preferably provided so as to be in a regular arrangement on the outer face of the cover fabric, an irregular arrangement, for example forming a pattern, also being conceivable, however.
  • honeycombed, outwardly open recesses may be variable in terms of the geometry thereof, and thus the open cross section thereof may be round or oval or angular for example.
  • the cover fabric consisting of weft-knitted 3D spacer fabric is formed in at least two layers, having an upper layer that forms the outer face, and a preferably polyester fibrous material woven fabric layer that forms an inner layer.
  • the inner layer forms a smooth woven fabric layer that may also be jacquarded and provided with a pattern for example, and on which woven fabric layer the upper layer of the weft-knitted 3D spacer fabric made of textured, twisted yarn, in particular multifilament yarn, is built up outwardly.
  • the honeycombed recesses may extend at least substantially over the entire thickness of the upper layer, i.e. from the outer face as far as the inner layer or close thereto, in order to allow for optimum conditioning with regard to the air and moisture exchange between the two sides of the cover fabric.
  • the depth of the honeycombed recess increases the softness of the weft-knitted 3D spacer fabric upper layer, as a result of which an improved feel can be achieved.
  • the cover fabric is formed in three layers, comprising a middle layer that is knitted to the upper layer and comprises a monofilament yarn as a filling material, stabilisation and volumisation (increase in volume) of the weft-knitted 3D spacer fabric, which volumisation is frequently desired in terms of feel, can be achieved at the same time as a high degree of air and moisture permeability.
  • the monofilament yarn may be formed of polyester, but other synthetic fibres, such as fibres formed of polyamide, are also possible therefor.
  • the surface surrounding the honeycombed recesses may be formed by particularly fine knitting stitches.
  • Tests have shown that it is particularly advantageous, with respect to comfort and micro-conditioning, for the upper layer of the weft-knitted spacer fabric to have a weight portion of cover fabric of from 50% to 70%, in particular from 55% to 60%.
  • the inner layer may have a weight portion of cover fabric of from 20% to 30%, in particular from 25% to 30%.
  • the cover fabric may have a weight of from 200 g/m 2 to 300 g/m 2 , as a result of which it has the required durability and is at the same time easy to handle, in terms of the weight thereof, both during production and during use.
  • the mattress cover may be designed so as to be the same on all faces, i.e. on the upper face, on the lower face and on the longitudinal and transverse sides that are formed when a mattress core is inserted, it also being conceivable in principle, however, for different faces of the mattress cover to also be designed differently.
  • the mattress cover In order to allow a mattress core to be inserted and removed, it is advantageous for the mattress cover to comprise a fastener, in particular a zip fastener, that is peripheral at least in part. Furthermore, in order to make it easier to handle the mattress that is covered by the mattress cover, grips may be sewn onto the mattress cover.
  • FIG. 1 is a schematic perspective view of a mattress cover that is designed according to the invention and has been put onto a mattress core;
  • FIG. 2 is a highly simplified plan view of a detail of an outer face of the mattress cover.
  • FIG. 3 is a schematic cross-sectional view through a region of a cover fabric of the mattress cover.
  • a mattress cover 1 can be seen in a state when stretched over a mattress core 2 , the mattress cover 1 forming, for a user sleeping thereon, a first lying surface on an upper face 3 and a second lying surface on an opposing lower face 4 .
  • the mattress cover 1 is formed by the same cover fabric 5 all the way around, lateral transverse surfaces 6 and longitudinal surfaces 7 also transitioning seamlessly, in the present case, into the upper face 6 and lower face 7 .
  • the surfaces of the cover fabric 5 may also be separated by stitched seams and a welting band may optionally also be provided.
  • a peripheral fastener 8 in the form of a zip fastener is sewn into the mattress cover 1 on the transverse surfaces 6 and longitudinal sides 7 .
  • a plurality of grips 9 for lifting the mattress core 2 , encompassed by the mattress cover 1 are provided on the lateral longitudinal surfaces 7 , just one of said grips or handles 9 being shown by way of example.
  • the cover fabric 5 is formed having a weft-knitted 3D spacer fabric 10 as far as the outer face 11 thereof, the cover fabric 5 having a honeycombed mesh structure having a regular, delicate arrangement of outwardly open recesses 12 .
  • the recesses 12 preferably have an oval cross section towards the outside, which cross section can be approximately 2 mm to 4 mm wide and approximately 3 mm to 5 mm long when unstretched.
  • the widths of the weft-knitted spacer fabric 10 material projections 13 located between the mutually offset and regular recesses 12 are at least approximately the same.
  • the cover fabric 5 of the mattress cover 1 is designed as a three-layer weft-knitted 3D spacer fabric comprising an upper layer 14 that forms the outer face 11 and is formed of a textured, twisted polyester multifilament yarn; a middle layer 15 that is made of a coarse polyester multifilament yarn, is knitted to the upper layer 14 , jointly forms the weft-knitted spacer fabric 10 and is used as a filling material; and a layer of smooth polyester yarn that is knitted to the upper layer 14 and the middle layer 15 and forms an inner layer 16 .
  • the upper layer 14 has a finely knitted structure 17 on the outer face 11 thereof, which structure provides the surface with a soft feel.
  • the upper layer 14 is dimensioned so as to occupy at least 70% to 80% of the total thickness of the cover fabric 5 , in order make use, as far as possible, of the microclimatic advantages of the weft-knitted spacer fabric 10 .
  • the honeycombed recesses 12 extend substantially over the thickness of the upper layer 14 and of the middle layer 15 until adjacent to the lower layer 16 such that, as a result of the recesses 12 , the cover fabric is very flexible and stretchable in the width direction.
  • the springiness in the height direction achieves a softness which can be defined, according to the desired degree of softness, by means of the filling material of the middle layer 14 .
  • the cover fabric 5 can be produced using all known methods for weft-knitting spacer fabrics on circular knitting machines, and using all known finishing methods, such as a washing, bleaching and shrinking process following the knitting process.
