Definitions

  • the invention relates to a single or multi-part duvet, in particular a provided with stitched chambers Quilt or duvet, according to the preamble of the claim 1.
  • the duvet Due to changed sleeping habits, the duvet, in particular their nature and quality, for the well - being of the User during its periods of rest a central importance won. Due to the usual renunciation of sheets the bed climate is determined primarily by the blanket. Essential for the duvet are their Isolation properties, in particular the ability to Temperature and humidity regulation, as well as the freedom of dust particles and organic allergens.
  • patent EP 0 594 798 B1 dust particles and organic allergens through regular washing be reliably eliminated.
  • House dust mites can be eliminate by adding textiles (sheets, clothes) at more be washed as 60 ° C for 60 minutes.
  • textiles sheets, clothes
  • filling materials consisting of down of ducks and geese are preferably used. Down, which are typically filled in the blankets in amounts of 150-350 g / m 2 , are able to absorb larger amounts of moisture, thus resulting in a favorable regulation of the humidity of the bed climate.
  • the ability to absorb moisture is also limited to down materials. Larger amounts of moisture, typically local in the area of certain body parts The user can usually not get enough fast be absorbed.
  • Another disadvantage is that the Insulation properties of the blanket after a longer time Moisture transfer or after taking larger Moisture levels in the areas of increased humidity unfavorably change.
  • Increased amounts of moisture can be known by supply dry air can be eliminated. This can be done with the blanket Openings are provided with breathable fabrics be completed and through which an exchange dry and moist air can take place.
  • the ceiling checkered in fields with raised and fields with split reduced air and moisture passage.
  • the disadvantage of this solution is that the body parts of the Sleeper not even against the outside from the ceiling abutting outside air are isolated. In the body area can therefore disturbing temperature gradients occur. Possibly Sensitive areas of the body are not immediately noticeable, but exposed to a lower temperature for a long time. It is also possible that when cuddling in the ceiling with the moisture-permeable fabrics covered openings be closed so that a moisture accumulation results. It is also possible that disturbing moisture gradients arise.
  • the present invention is therefore based on the object to create an improved duvet.
  • one is To create duvet by means of throughout the entire Duration of use a more pleasant bed climate with deep Moisture is feasible.
  • a blanket is to create at the disturbing Temperature and humidity gradients are avoided.
  • the inventive blanket in particular a on or multipart quilt or duvet, has one heat-insulating, hydrophilic filling on between two first textile layers caught in one or more chambers is.
  • both are preferably first Textile layers of a relatively hydrophobic first fabric, the transport of water vapor serving pores and capillaries and at least partially with a on or multilayered second textile layer is covered out a pronounced hydrophilic and water vapor permeable second substance exists.
  • the second textile layer is the one submitted by the user Moisture by absorption or adsorption / desorption rapidly picked up, spread out and over the pores of the relative hydrophobic first textile layer to the hydrophilic, preferably made of down filling existing, which a high Has capacity for the absorption of water vapor.
  • the relatively hydrophobic first textile layer will cause itself the one given by the user and by the possibly existing bedding passed through moisture over the hydrophilic second textile layer, according to which due to the resulting difference in vapor pressures both sides of the first textile layer in the hydrophilic second textile location stored water vapor through the relative transferred hydrophobic first textile layer and from the hydrophilic filling is absorbed.
  • the solution of the task does not succeed by the local removal of Materials, which partially increased breathability achieved by the large-scale use of a further textile location. Particularly important is that the Moisture does not evaporate on the user's skin, causing a partial cooling of the skin surface results, but first through the adjacent textiles is recorded.
  • Essential in the invention is not the absolute value the hydrophobicity of the first textile layers, but the relative Differences in water absorption properties of the first and second textile layers.
  • good results are achieved when the time to absorption a drop of water through the fabric of the first two Textile layers at least twice as large as the duration for absorbing a drop of water, under the same Conditions, by the fabric of the two second textile layers. Very good results were achieved with a factor of 5.
  • the fabric of the two second textile layers also shows preferably a water vapor transmission resistance Ret ISO standard 11092 of maximum 20 m2 / Pa / W, preferably about 5 m2 / Pa / W, up.
  • Water vapor resistance of textiles are for example by means of the standards ISO 11092 and ASTM F-1868 Working Gauges Model SGHP-8.2 and Model SGHP-10.5 of the company Measurement Technology Northwest, Seattle, WA 98199, measurable.
  • the second textile layers are also markedly hydrophilic breathable fabrics usable in which the Water vapor transfer not primarily by adsorption and Desorption takes place.
  • a substance is used which has coarse mesh or pores whose diameter at least twice as large as the diameter of the Mesh or pores of the fabric of the first two textile layers. In the use of large pores, however, is the Total or partial elimination of mite seal note.
  • the second textile location is supposed to be as optimally as possible to the one or both sides of it Clinging to adjacent textile layers.
  • the second textile layer chosen fabrics whose shear stiffness half as large as the shear stiffness of the Fabric of the first two textile layers. This shows that the measurement of the shear stiffness is very good with the subjective grip rating correlated.
  • Shear stiffness is measured, for example, the force that is necessary to have a horizontally clamped textile strip subject to a parallel shift. Further Measuring methods are known from [3], page 30.
  • the hydrophilic second textile layer is provided with bonding agents such as stitching, Velcro, buttons or zippers fixed or detachable by the user with the associated relatively hydrophobic first textile layer connected. Is possible furthermore, with the hydrophilic second textile layers, an envelope too form, to receive one from the first textile layers and the filling formed Duvetdecke is suitable.
  • the second textile layer By using the second textile layer also results in a improved insulation, allowing a thinner down filling can be provided.
  • a third, heat-insulating Textillage be provided, preferably also from made of a hydrophilic material, whereby the lateral Transfer of moisture is still noticeably improved.
  • the hydrophilic second textile layer covers the relatively hydrophobic first textile layer completely or is preferably only in the area provided above the expected position of the user's body.
  • a further preferred embodiment is outside the area of the duvet that is above the expected Position of the user's body is at least one Provided breathable zone that does not have hydrophilic filling and that an air exchange between the bed climate and the indoor climate allowed.
  • breathable zone that does not have hydrophilic filling and that an air exchange between the bed climate and the indoor climate allowed.
  • serpentine or narrow are rectangular designed breathable zones on both sides of the area provided that exceeds the expected position of the body the user lies, so only a small and smoother, for the user quite pleasant Heat output can result.
  • the breathable zones are in doing so by the first and / or the second textile layer; or alternatively by the first and / or the second textile layer and covered at least one heat-insulating third textile layer; so that disturbing air movements and insulation gaps avoided become.
  • the within and / or outside the body area breathable zones lockable, so that an adjustment of the Ceiling to the seasonal climatic conditions is possible.
  • Individual end caps can be provided by means of Velcro straps, buttons or zippers on the Rims of the breathable zones are fastened. This However, especially during assembly of the individual causes Endpieces a considerable effort. Furthermore, the Storage of individual endpieces rather unvorteilhaftrealisierbar. According to the invention, therefore, two complementary to each other and by means of seams, Velcro closures, buttons or zippers with each other connectable ceiling parts provided, of which the first with the breathable zones and the second with corresponding arranged end pieces is provided. The two Ceiling parts can therefore quickly in the manner of LEGO® blocks be connected or disconnected.
  • the Storage of the complementary first or second ceiling part is much easier than the storage of the individual Terminations. Particularly advantageous in this solution.
  • three duvet types are feasible. For example, in the summer only the breathable one can do so Zones provided first ceiling part can be used. In the Transition times, in spring and autumn can be the easy second provided with the end pieces ceiling part used and in winter, the combination of both ceiling parts used. Furthermore, the two ceiling parts can also be necessary can be used separately. It is possible to use two to each other only partially complementary ceiling parts, at their connection to respiratory zones not or only partially filled.
  • the distinctly hydrophilic second textile layer can be a on or multilayer, coarse mesh, fine mesh or microporous Fabric, a knitted fabric, a knitted fabric or a nonwoven fabric Chemical and / or natural fibers.
  • Advantageously usable For example, cotton, nylon or polyamide.
  • Synthetic textiles including nonwovens, were used in strongly improved recently, so that their Properties of those of natural products, for example Cotton, strongly approximated. Synthetic textiles also have a high variability, which allows to optimize the substance for the present application. Synthetic textiles also have good mechanical properties Resistance to abrasion, tearing and tearing, high breathability, isotropic properties (after all Directions equally resilient with the benefits of traditional Woven and knitted fabric), a textile handle, good drape and a high ease of use.
  • mite and allergen dense become second Textile layers with a maximum pore size of 0.5 ⁇ m used, which have pronounced hydrophilic properties and at the same time prevent the ingress of mites.
  • a ceiling middle part that by means of connecting devices, For example, zippers, one or both sides with Ceiling side panels connectable or connected.
  • connecting devices For example, zippers, one or both sides with Ceiling side panels connectable or connected.
  • the breathable zones for the regulation of the bed climate in the ceiling middle section or in the ceiling side panels be provided.
  • the breathable zones preferably provided eccentrically, so that each ceiling side panel in a first and a second Textillage is connectable to the ceiling middle section, provided it on both sides corresponding parts of the connecting device having. Users with a larger body size can use the Therefore mount ceiling side panels in such a way that a larger one Distance between the breathable zones results. For narrower users or calmer sleepers may be be less distance between the openings to be preferred.
  • the connecting devices are preferably by means of Insulating cloths covered, so they are not directly on the body abut the user and form annoying thermal bridges can.
  • the Isolierlappen are preferably with the ceiling middle part connected so that they, facing away from the user, are directed to the outside. It is possible to use one or multiwall, optionally with insulation material filled insulating flaps, the one-sided or both sides of the Duvet are arranged, the connecting devices preferably completely cover and if necessary enclose annular. Unless the ceiling sides provided on both sides with parts of the connecting device are insulating laps are preferably on both sides of the Ceiling side panels provided so that prevents Parts of the connecting device can be exposed.

  • FIG. 1 shows the structure of a duvet according to the invention 1A, which is an example of down filling 10, on both sides of subsequent hydrophobic or weak hydrophilic first textile layers 11, 12 and outside adjacent distinctively hydrophilic second textile layers 13, 14 having.
  • first textile layers 11, 12 used substances not absolutely hydrophobic, but in the Relationship with the substances of the second textile layers 13, 14 are relatively hydrophobic.
  • FIG. 1 Above the upper second textile layer 13 of FIG a single or multi-layered hydrophilic fabric or laminate there are shown water droplets that are hydrophilic second textile layer 13 is absorbed and along the fibers of the Stoffs or laminate are distributed flat.
  • the under the hydrophilic second textile layer 13 provided relative hydrophobic first textile layer 11 prevents larger ones Moisture levels locally into the hydrophilic filling 10 enter and moisten the down there, which is what affect their properties during use and then a longer airing or drying out would make necessary.
  • the lies Moisture or the steam then with strong reduced density distributed over the surface of the relatively hydrophobic first textile layer 11 and can by the provided therein numerous channels or pores and capillaries 111 through them pass through and into the hydrophilic filling 10.
  • This Process is governed by the difference of vapor pressure and Temperature on both sides of the relatively hydrophobic first textile layer 11 driven and accelerated.
  • a higher average vapor pressure difference over larger areas therefore results in a faster Moisture transfer and thus a drier and a pleasant bed climate.
  • the hydrophilic filling 10 on One side of the moisture is on the other side through the local relatively hydrophobic textile layer 12 therethrough guided and from there hydrophilic second textile layer 14th absorbed and released into the room or outside air.
  • a hydrophilic third textile layer 15 is fixed or detachable with the first or second textile layer 11 or 13 connected. Due to the hydrophilic third textile layer 15, for example, a layer of natural fibers such as cotton, takes place a further areal distribution of moisture and Reduction of local water vapor density. It also results a better heat insulation. The user can therefore for the Winter months the third textile layer 15 solvable with the first or second textile layer 11 or 13 connect to the Features of the bedspread 1A a changed climate adapt.
  • the first and second textile layers 11, 13 and 12, 14 are releasably connected to each other or form, firmly together connected, a laminate, as shown in Figure 3.
  • Figure 3 also shows the construction of a duvet 1B, the two has breathable zones 3, in which no filling 10th is provided. If stronger in these areas Air movements occur, the water vapor is thereby rapidly led to the outside.
  • These breathable zones 3 are preferably arranged outside the area 4, the over the expected position of the user's body. For example, the breathable zones 3 in the arranged thirds or quarters of the blanket. This prevents the breathable zones 3 through covered the body of the user, causing the Air exchange would be hampered.
  • the breathable zones 3 are also disturbing Avoid temperature gradients that occur because of the Insulation properties of the duvet in the area of breathable zones is changed, the body of the user is exposed to barely noticeable air currents and moisture evaporate on the skin or clothing of the user can.
  • the breathable zones 3 shown in FIG. 3 are laterally limited by the filling 10, for example by means of stitched together upper and lower first textile layers 11, 12 is caught. Above and / or below is the breathable Zone 3 by means of the first and / or the second textile layer 11, 12 or 13, 14 and optionally with an insulating third textile location 15 covered by the insulation value the blanket also in the breathable zones 3 largely is kept constant.
  • the breathable zones 3 are on both sides the first and second textile layers 11, 13 and 12, 14 covered.
