Description

Cover for a mattress or pillow

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application claims priority from german utility model application 20 2020 104776.0, filed 8/18/2020 and which is incorporated by reference in its entirety in the present application.

Technical Field

The invention relates to a cover for a mattress and/or a pillow, in particular a mattress cover, a mattress protection cover, a pillow cover and/or a pillow protection cover. The outer cover has an outer cover fabric which is at least partially, in particular completely, formed from an interlaced weft knit (Abstandsgestrick).

Background

Covers for mattresses and/or pillows generally known from practice (also referred to below as mattress covers and/or pillow covers) are usually provided for the close-fitting wrapping of a mattress core or pillow core which has a length and a width at the upper and lower sides which can be greater than the height, for example, and which can form a lying surface for a person and/or a support surface for a person's head.

Mattress covers and/or pillow covers are usually made up of a fabric area forming the upper side and a fabric area forming the lower side. In a removable cover, which enables the introduction or removal of a mattress core or pillow core into or out of the cover, a closure, for example in the form of a zipper, is usually provided for this purpose.

Depending on the design of the cover, the upper and lower fabric regions can be formed by their own fabric panels forming the respective lying or lower side, which can optionally be connected to one another by fabric strips forming the longitudinal and transverse sides. Such fabric strips are usually connected to the upper and lower fabric panels by seams, wherein the seams can be covered by a welt band or a waterproof strip.

In the covers known from practice, in particular mattress covers, ventilation strips made of a material with high permeability to other cover fabrics are furthermore often used on the longitudinal and transverse sides, since the usual cover fabrics for covers usually have only a low permeability to air and the mattress core or pillow core is otherwise insufficiently ventilated.

From DE 20 2012 005 880 U1, for example, it is known to construct a mattress cover in two parts, such that one side is formed as a winter cover from a viscoelastic foam material and the other side is formed as a summer cover from an spacer warp knit (abstandsgegirk), also referred to as a 3D spacer warp knit, which, due to its high breathability, produces a better microclimate for the sleeper. However, the disadvantage here is that the spacer warp knitted fabric is relatively rigid and inflexible, as a result of which the configuration for the lying comfort of the sleeper is limited.

Disclosure of Invention

The spacer weft knitted fabric is stretchable owing to its different structural configuration with respect to the spacer warp knitted fabric, whereby in principle an improvement in comfort for the user is possible in the case of an outer cover for a mattress and/or a pillow formed by means of the spacer weft knitted fabric, since it can be constructed soft, elastically and with a pleasant tactile feel.

In practice, it has however proved that with the known spacer weft fabrics, there is a need for improvement with regard to air permeability and lying comfort, in particular when used as a cover for mattresses and/or pillows.

Furthermore, known covers for mattresses and/or pillows are made almost exclusively of synthetic fibres. This can involve economic disadvantages on the one hand and, on the other hand, the lying comfort of the user can be reduced thereby, for example because the rayon can be perceived as relatively cool.

The present disclosure enables, among other things, providing an improved cover for a mattress and/or pillow, which cover is characterized by, for example, increased breathability, a comfortable and soft lying surface or outer side, and cost-effective processability.

This is achieved in particular by the subject matter of the independent claims. Further embodiments are described in the dependent claims and in the following description.

One aspect of the present disclosure relates to a cover for a mattress, a cover for a pillow, a mattress cover, a mattress protective cover, a pillow protective cover, and/or a pillow cover. The outer cover has an outer cover fabric having at least an upper layer and a lower layer. The upper layer can represent the outer layer of the outer cover fabric and the lower layer can represent the inner layer of the outer cover fabric. The upper and lower layers are arranged at least partially one above the other. For example, the upper and lower layers can be at least partially stacked on each other. At least the upper layer of the outer shell fabric is furthermore formed by a spacer weft, for example a 3D spacer weft, wherein a plurality of recesses are formed at least on the outer side of the upper layer facing away from the lower layer, which outer side can be used, for example, as a bed for a user and/or as a support surface for the head of a user. Furthermore, the upper and/or lower layers of the outer cover fabric are at least partially composed of natural fibers.

The cover according to the invention thus takes advantage of the advantage of a spacer weft knit, for example having a spacer structure with mesh threads, for example consisting at least partially of braided monofilament or multifilament threads that maintain the spacing.

Furthermore, the recess formed at the outer side enables increased air circulation, increased air permeability and/or increased dehumidification.

Furthermore, by using natural fibers, which can be included and/or woven in the spacer weft fabric, for example, the durability and/or economy of the outer cover can be improved, for example, because the natural fibers can be obtained from grown raw materials. Natural fibers can also be characterized by increased load capacity and/or abrasion resistance. In addition, natural fibers can create a comfortable, soft touch for the user. Natural fibers can also be characterized by increased skin compatibility, breathability, and/or no odor. Furthermore, natural fibers enable cost-effective manufacturing of the outer cover.

The spacer weft knit fabric used for the outer cover differs from the spacer warp knit fabric typically used for the outer cover in several respects. For example, spacer warp knits are usually produced on so-called warp knitting machines, while spacer weft knits are usually produced on weft knitting machines, wherein additionally a distinction is made between flat weft knitting machines and circular weft knitting machines. In the production of a spacer warp knit fabric, the wires are arranged around the warp yarns (and hence also the warp knitting machine). The wires are arranged vertically next to one another. Due to the arrangement of the mesh wires around the warp yarns, the spacer warp knit is stable, rigid, inelastic and inextensible. In contrast, the wires of the spacer weft fabric are not arranged next to one another around the warp threads, but the wires themselves can be elastic and stretchable, that is to say in the horizontal direction and in the vertical direction. In contrast to spacer warp knitted fabrics, spacer weft knitted fabrics can therefore be characterized in particular in that they are elastic and stretchable not only in the horizontal direction but also in the vertical direction, whereas spacer warp knitted fabrics are in contrast completely inelastic and non-stretchable. The spacer warp knit is thus a static and rigid textile structure having only little or no elasticity. In addition, the spacer warp knit fabric has a rigid, hard, and plastic-like feel, while the spacer weft knit fabric can have a woven or fabric-like and soft feel. Furthermore, in the case of a spacer warp knit, the fiber ends typically protrude from the surface of the warp knit, so that a pricked and rough touch is present. In contrast, spacer weft knits generally have a significantly softer feel, which is sometimes caused by the improved elastic properties of the spacer weft knits and the significantly finer processing compared to the spacer warp knits.

If the cover is designed as a mattress cover or mattress protection cover, the cover can have an upper side and/or a lower side, which can each be dimensioned for a lying surface of a user. If the cover is configured as a pillow cover (or pillow protection cover), it can have an upper side and/or a lower side, which can be dimensioned for the support surface of the user's head, respectively.

The openings formed at least on the outer side of the upper layer of the outer shell fabric are in the context of the present disclosure strictly distinguished from the mesh threads which can be used to form the outer shell fabric, the lower layer and/or the upper layer. The recess can be dimensioned larger than the mesh wire, for example the cross section of the recess can be several times larger (for example 5 to 100 times or more) than the average cross section of the mesh wire of the casing fabric.

The outer shell fabric can generally be constructed in two layers, three layers or more. In particular, the outer cover fabric can be produced and/or composed entirely of a spacer weft knit fabric and/or a 3D spacer weft knit fabric.

In the case of a two-layer design of the outer shell fabric, the upper layer and the lower layer can be connected to each other and/or knitted at least in sections, for example in spots, by means of the threads of the upper layer and/or of the lower layer. Alternatively or additionally, connecting threads can be used, which can connect the upper and lower layers. In the three-layer or multi-layer construction of the shell fabric, one or more intermediate layers of the shell fabric can be connected to and/or woven with the upper and/or lower layer. Alternatively or additionally, connecting threads can also be used here, which can connect at least two layers of the shell fabric, for example an upper layer, a lower layer and/or one or more intermediate layers.

The cover according to the invention can be produced in a simple manner, for example on large circular weft knitting machines operating according to the so-called 3-way technology, with a high throughput in terms of time and thus with high economy.

According to one embodiment, the natural fibers are animal wool fibers, cotton fibers, hemp fibers, eucalyptus fibers, bamboo fibers, hemp fibers, wood fibers, viscose fibers, flax fibers, silk fibers, plant fibers, or a combination thereof. Such natural fibers are characterized by improved durability, odor neutrality, skin compatibility, abrasion resistance, and/or robustness, for example, as compared to rayon fibers.

According to one embodiment, the upper layer, the lower layer and/or the one or more intermediate layers of the shell fabric have a weight share of natural fibers of 2% to 99%, for example at least 5%, at least 10%, at least 15%, at least 20% and/or at least 25%, for example based on the respective layer or the shell fabric as a whole. At least 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70% or 75% natural fibers are also contemplated.

According to one embodiment, the proportion, for example the weight and/or volume proportion, of the natural fibers in the upper layer, for example in the respective layer or the entire outer cover fabric, is greater than the proportion, for example the weight and/or volume proportion, of the natural fibers in the lower layer and/or in one or more intermediate layers. For example, the share in the upper layer can be at least twice as large as the corresponding share of natural fibers in the lower layer and/or one or more intermediate layers.

According to one embodiment, the upper layer consists essentially and/or almost completely, e.g. completely, of natural fibres, and the lower layer, and optionally one or more intermediate layers consist essentially and/or almost completely, e.g. completely, of artificial fibres.

The recess can be designed to be open to the outside, i.e. in the direction of the user, and/or have an outwardly open cross section. The empty space can thus represent an opening. The recess can be advantageous here in general with regard to ventilation and dehumidification and compensation of temperature fluctuations. The recess can also provide increased elasticity, which can provide the user with a soft touch and can furthermore allow the cover to be adapted in an optimal manner to the user or the head lying on it without said cover being damaged by the generally perceptible, brittle spacing-maintaining threads in the spacer warp knit.

The recess formed at least on the outer side of the upper layer can also provide and/or form a mesh structure of the outer covering fabric. In other words, the casing fabric can have a mesh structure, for example a honeycomb mesh structure, at least at the outer side, which mesh structure has a recess.

The openings of the wire structure and/or the outer cover fabric can be arranged regularly on the outer side of the outer cover fabric, for example. In other words, the cut-outs can be arranged regularly and/or in a regular pattern. However, irregular arrangements, for example in the form of patterns, are also conceivable.

The recess, for example an outwardly open recess, can be varied with respect to its geometry such that it is formed in its open cross section, for example, in a circular, angular, oval, quadrangular, elliptical or also in any other shape.

For example, the hollow portion can be formed in a honeycomb shape. Alternatively or additionally, the recess can have a round, rounded, angular, quadrangular, rectangular, polygonal, triangular, elliptical, oval and/or polygonal cross section.

According to one embodiment, the upper and/or lower layer of the outer covering fabric is at least partially composed of textured, twisted yarns, in particular multifilament yarns, for example polyester, polyethylene, polyamide, polyethylene and/or polyamide yarns. Thereby providing a soft and comfortable tactile sensation.

According to one embodiment, the upper and/or lower layer of the outer covering fabric is at least partially composed of monofilament yarns, in particular polyester yarns, smooth polyester yarns, polyethylene yarns, smooth polyethylene yarns, polyamide yarns and/or smooth polyamide yarns. When the outer cover fabric is composed of monofilament yarns at the lower side of the outer cover fabric facing the mattress core or pillow core, it is possible to make the mattress core or pillow core easy to remove or introduce.

For example, the outer cover fabric can consist of a spacer weft-knitted fabric which has at least two layers with an upper layer forming the outer side and a fabric layer, preferably consisting of a polyester fiber material, a polyethylene fiber material and/or a polyamide fiber material, forming the inner or lower layer.

The inner or lower layer can be, for example, a smooth fabric layer, which can also be patterned and/or provided, for example, with a pattern, on which the upper layer of the spacer weft fabric composed of textured, twisted yarns, in particular multifilament yarns, can be built up to the outside.

According to one embodiment, the casing fabric also has an intermediate layer which is at least punctiform and/or at least partially woven with the upper and/or lower layer. The intermediate layer can be used for bulking the outer cover fabric. This also increases the comfort of the user lying.

According to one embodiment, the intermediate layer is at least partially made of monofilament yarns, in particular polyester yarns, smooth polyester yarns, polyethylene yarns, smooth polyethylene yarns, polyamide yarns and/or smooth polyamide yarns.

According to one embodiment, the intermediate layer is at least partially composed of a multifilament yarn, for example of a textured, twisted multifilament yarn, for example of polyester, polyethylene, polyamide, polyethylene and/or polyamide yarns.

According to one embodiment, the intermediate layer is at least partially made of natural fibers. Here, the advantages set forth above with respect to natural fibers are provided.

According to one embodiment, the recess extends at least substantially within the thickness of the upper layer and the possible intermediate layer. In particular, the recess can extend completely through the upper layer, so that the recess appears to constitute and/or be a cut in the upper layer.

The recess can, for example, extend at least substantially over the entire thickness of the upper layer, i.e. the outer side up to or close to the inner or lower layer, for example in order to enable optimized air conditioning with respect to the exchange of air and moisture between the two sides of the outer cover fabric. Further, the depth of the space can increase the flexibility of the upper layer composed of the spacer weft, whereby an improved tactile sensation can be obtained.

The outer fabric can furthermore be constructed in three layers with a middle layer, for example a layer woven with the upper layer, having monofilament yarns as filling material. In this case, the stability and the generally desired fullness in the touch of the spacer weft can be achieved with a simultaneously high permeability to air and moisture. The monofilament yarns can be formed, for example, at least partially from polyester, polyamide and/or polyethylene, although other synthetic fibers can also be used for this purpose.

In order to give the surface or the outer side of the spacer weft fabric facing the outside a particularly smooth and pleasant tactile feel, the surface or the outer side surrounding the recess can be formed by a finer weft mesh than the remaining area of the outer side.

According to one embodiment, the upper layer has a weight proportion of 50% to 70%, in particular 55% to 60%, of the outer shell fabric. Studies have shown that the stated weight portions are particularly advantageous with regard to comfort and micro-air conditioning.

According to one embodiment, the lower layer has a weight proportion of 20% to 30%, in particular 25% to 30%, of the outer cover fabric.

According to one embodiment, the intermediate layer has a weight proportion of 10% to 20%, in particular 15% to 20%, of the outer shell fabric.

When using the filling material, the optimum results with respect to breathability, stability and fullness are determined when the central layer has a weight share of the outer shell fabric of 10% to 20%, in particular 15% to 20%.

According to oneEmbodiment, the outer cover fabric has 250g/m ² -300g/m ² The weight of (c). The shell fabric can thereby have the required abrasion resistance and at the same time be easily handled with regard to its weight during manufacture, for example during use.

According to one embodiment, the cover fabric is formed identically at all sides. In other words, the outer casing can be formed identically on all sides, i.e. on the upper side, on the lower side and on the longitudinal and transverse sides which may be present, wherein in principle it is also conceivable, however, for different sides of the outer casing to be formed differently.

The overall side is of identical design, which enables particularly simple production, wherein the ventilation strips at the transverse and longitudinal sides, which are usually found in known covers, in particular mattress covers, can also be dispensed with due to the high air permeability of the cover fabric.

According to one embodiment, the housing has an at least partially encircling closure, in particular a zipper, which can be opened or closed for inserting or removing the mattress core and/or the pillow core. In order to be able to insert and remove the mattress core or pillow core, it can be advantageous if the casing has an at least partially encircling closure, in particular a zipper.

Furthermore, for easier handling of the covered mattress, handles can be sewn to the cover.

The outer cover can also be washable, e.g., at a temperature of at least 30 ℃, at least 40 ℃, at least 50 ℃, at least 60 ℃, at least 70 ℃, at least 80 ℃, or at least 90 ℃.

Another aspect of the invention relates to the use of an outer cover fabric for the outer cover of a mattress and/or pillow. The outer cover fabric has at least one upper layer and one lower layer, wherein the upper layer and the lower layer are arranged at least partially one above the other, and wherein at least the upper layer of the outer cover fabric is formed by a spacer weft-knitted fabric, for example a 3D spacer weft-knitted fabric. At least on the outer side of the upper layer facing away from the lower layer, a plurality of recesses are formed, wherein the upper and/or lower layer of the outer shell fabric is at least partially formed from natural fibers.

Further advantages and advantageous refinements of the invention emerge from the claims and the exemplary embodiments described in principle with reference to the figures.

Detailed Description

With reference to fig. 1, an outer cover 1 or a mattress cover 1 (or a mattress protective cover 1) is exemplarily shown in a state tensioned onto a mattress core 2, wherein the cover 1 forms a first lying surface at an upper side 3 for a user sleeping thereon and a second lying surface at an opposite lower side 4. The cover 1 of fig. 1 is shown merely as an example as a mattress cover (or mattress protective cover). Alternatively or additionally, the housing 1 can be designed as a pillow housing for accommodating a pillow core and/or as a pillow protection housing.

The cover 1 is formed circumferentially from the same cover fabric 5, wherein the lateral transverse sides 6 and the longitudinal sides 7 optionally merge seamlessly into the upper side 6 and the lower side 7. In contrast, however, in other embodiments it can also be provided that the sides of the casing fabric 5 are separated by seams and, if appropriate, waterproof strips.

In particular in the case of a cover 1 designed as a pillow cover (or pillow protection cover), the transverse faces 6 and the longitudinal faces 7 are eliminated.

At the transverse sides 6 and the longitudinal sides 7, in order to introduce and remove the mattress core 2, a circumferential closure in the form of a zipper is sewn into the mattress cover 1 (or mattress protection cover 1). Furthermore, a plurality of handles 9 are provided at the lateral longitudinal sides 7 in order to lift the mattress core 2 enclosed by the mattress cover 1 (or the mattress cover 1), wherein only one handle 9 is shown by way of example.

As in fig. 1, the detail X representing the entire surface of the mattress cover 1 (or of the mattress protective cover 1) and visible in fig. 2 and 3, the cover fabric 5 is formed, apart from its outer side 11, by means of a spacer weft 10, for example a 3D spacer weft.

The casing fabric 5 has a honeycomb-like mesh structure with outwardly open recesses 12 in a regular, elongate arrangement. The recess 12 preferably has a round, rounded, elliptical and/or oval cross section facing outward, which in the untensioned state can be dimensioned, for example, to have a width of 2mm to 4mm and a length of approximately 3mm to 5mm.

The material webs 13 of the spacer weft 10 which are present between the regularly arranged recesses 12 which are offset from one another can be dimensioned in terms of their width at least approximately equally.

The cover fabric 5 of the cover 1 is constructed here as a three-layer spacer weft fabric with an upper layer 14 forming the outer side 11, an intermediate layer 15 which together form the spacer weft fabric 10 and which is knitted with the upper layer 14, and an inner or lower layer 16 which is knitted with the upper layer 14 and/or the intermediate layer 15.

The upper layer 14 can have a monofilament yarn, such as a smooth monofilament yarn, or a multifilament yarn, such as a textured, twisted multifilament yarn. Similarly, the lower 16 pages can have monofilament, e.g., smooth monofilament, or multifilament, e.g., textured, twisted multifilament. Likewise, the intermediate layer 15 can be at least partially composed of a monofilament or a multifilament yarn.

One or more of the upper layer 14, the intermediate layer 15 and the lower layer 16 also comprise and/or are at least partially composed of natural fibers, as described hereinabove. The natural fibers can be, for example, animal hair fibers, wool fibers, cotton fibers, hemp fibers, eucalyptus fibers, bamboo fibers, hemp fibers, wood fibers, viscose fibers, flax fibers, silk fibers, plant fibers, or combinations thereof. Such natural fibers are characterized by improved durability, odor neutrality, skin compatibility, abrasion resistance, and/or robustness, for example, as compared to rayon fibers.

The upper layer 14 furthermore has a fine-weave structure 17 at the outer side 11, which gives the surface a soft tactile feel.

With regard to the thickness, the upper layer 14 is dimensioned in the shown advantageous embodiment such that it occupies at least 70% to 80% of the total thickness of the outer cover fabric, in order to exploit as much as possible the microclimate advantages of the spacer weft fabric 10.

In order to be able to achieve as large an air circulation as possible and an optimum dehumidification to the outside 11, the honeycomb-like cutouts 12 extend over substantially the entire thickness of the upper layer 14 and the middle layer 15 up to adjacent to the lower layer 16, so that the outer covering fabric has both flexibility and stretchability in width through the cutouts 12. The elasticity in height causes flexibility, which can be defined by the filling material of the intermediate layer 14, depending on the desired degree of flexibility.

It goes without saying that the casing fabric 5 can be produced, depending on the application, by all known spaced weft knitting methods, for example on circular weft knitting machines, and by all known finishing methods, for example by washing, bleaching and shrinking processes following the knitting process.

It is additionally noted that "comprising" and "having" do not exclude other elements and that the indefinite article "a" or "an" does not exclude a plurality.

It is furthermore noted that features described with reference to one of the above embodiments can also be used in combination with other features of other embodiments described hereinbefore. Reference signs in the claims shall not be construed as limiting.
