Definitions

  • the invention relates to a single or multi-part duvet, in particular a quilt or duvet cover provided with stitched chambers, according to the preamble of patent claim 1.
  • the duvet Due to changed sleeping habits, the duvet, in particular its nature and quality, has gained a central importance for the well-being of the user during his resting periods. Due to the usual renunciation of linen sheets, the bed climate is determined primarily by the blanket. Essential for the duvet are their insulation properties, in particular the ability to regulate temperature and humidity, as well as the freedom from dust particles and organic allergens.
  • DE-A-196 54 798 and FP-A-0 323 116 describes blankets which have a covering which makes it possible to effectively combat allergic phenomena in allergy sufferers.
  • inner shell material which on the one hand is highly permeable to air and on the other hand highly captive for small particles.
  • DE-A-196 54 798 is also proposed, in addition to this inner shell to use an outer shell having properties, such as mechanical structural strength, which are not provided in the inner shell.
  • 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 in down materials. Larger amounts of moisture, which typically occur locally in the area of certain areas of the user's body, usually can not be absorbed sufficiently quickly.
  • Another disadvantage is that the insulation properties of the blanket change unfavorably after prolonged moisture transfer or after receiving larger amounts of moisture in the areas of increased humidity.
  • the ceiling can be provided with openings that are closed with breathable fabrics and through which an exchange of dry and moist air can take place.
  • the blanket is split into checkerboard-like fields with reduced air and moisture passages.
  • a disadvantage of this solution is that the body areas of the sleeper are not uniformly insulated against the outside air abutting the outside of the ceiling. Therefore disturbing temperature gradients can occur in the body area. If necessary, sensitive parts of the body are not immediately noticeable, but are exposed to a lower temperature for a longer time. It is also possible that, when cuddling in the ceiling, the openings covered with moisture-permeable substances are 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 provide an improved duvet.
  • a blanket is to be created by means of which a more pleasant bed climate with low moisture values can be realized during the entire period of use.
  • a blanket is to be created in which disturbing temperature and humidity gradients are avoided.
  • the blanket according to the invention in particular a one- or multi-part quilted or duvet blanket, has a heat-insulating, hydrophilic filling which is trapped between two first textile layers in one or more chambers.
  • both first textile layers preferably consist of a relatively hydrophobic first material which has the transport of pores and capillaries serving for water vapor and which is at least partially covered by a single or multi-layered second textile layer, which consists of a distinctly hydrophilic and water-vapor-permeable second material.
  • the moisture released by the user is rapidly absorbed by absorption or adsorption / desorption, distributed over the pores of the relatively hydrophobic first textile layer to the hydrophilic, preferably down, filling, which has a high capacity for absorbing water vapor having.
  • the relatively hydrophobic first fabric layer causes the moisture given off by the user and passed through the optional bedding to spread rapidly across the hydrophilic second fabric layer, whereafter, due to the resulting difference in vapor pressures on both sides of the first textile layer hydrophilic second textile layer stored water vapor through the relatively hydrophobic first textile layer is transferred and absorbed by the hydrophilic filling.
  • the moisture is then released through the opposite relatively hydrophobic first textile layer and, if present, the subsequent hydrophilic second textile layer.
  • the blanket according to the invention therefore results in a rapid transfer of moisture and thus a dry bed climate, disturbing moisture gradients are avoided.
  • By avoiding larger openings for moisture transfer temperature and pressure gradients are further avoided, which could be perceived by the user as unpleasant.
  • the solution of the problem is therefore not achieved by the local removal of materials, which partially increased breathability is achieved, but by the large-scale use of another textile layer. Particularly important is that the moisture does not evaporate on the skin of the user, resulting in a partial cooling of the skin surface, but is first absorbed by the adjacent textiles.
  • the fabric of the two second textile layers also preferably has a water vapor transmission resistance Ret according to ISO standard 11092 of not more than 20 m 2 / Pa / W, preferably about 5 m 2 / Pa / W.
  • Textile water vapor resistance can be measured, for example, by means of SGHP-8.2 and SGHP-10.5 measuring instruments of Measurement Technology Northwest, Seattle, WA 98199, which operate according to ISO 11092 and ASTM F-1868 standards.
  • hydrophilic breathable substances are also usable for the second textile layers, in which the water vapor transfer does not take place primarily by adsorption and desorption.
  • a substance is preferably used which has coarse mesh or pores whose diameter is at least twice as large as the diameter of the mesh or pores of the fabric of the first two textile layers.
  • the second textile layer should cling as optimally as possible to the textile layers lying on one or both sides.
  • substances whose shear stiffness is at most half as high as the shear stiffness of the fabric of the first two textile layers are selected for the second textile layer. This shows that the measurement of the shear stiffness correlates very well with the subjective grip assessment.
  • the shear stiffness for example, the force required to subject a horizontally clamped textile strip to parallel displacement is measured. Further measuring methods are known from [3], page 30.
  • the hydrophilic second textile layer is fixed by connecting means such as stitching, hook-and-loop fasteners, buttons or zippers, or releasably connected by the user to the associated relatively hydrophobic first textile layer. It is also possible to form an envelope with the hydrophilic second textile layers which is suitable for receiving a duvet cover formed from the first textile layers and the filling.
  • a third, heat-insulating textile layer can be provided over the entire surface, which is preferably also made of a hydrophilic material, whereby the lateral transfer of moisture is still noticeably improved.
  • the hydrophilic second textile layer completely covers the relatively hydrophobic first textile layer or is preferably provided only in the region which lies above the expected position of the body of the user.
  • At least one breathable zone is provided outside the area of the blanket, which is above the expected position of the body of the user, which has no hydrophilic filling and the air exchange between the bed climate and the room climate allowed.
  • the movements of the user result in pumping operations, by means of which dry air is sucked in and moist air is expelled.
  • the user therefore forms a kind of drive, by means of which the regulation process is automatically driven and controlled.
  • the regulation process In a user who suffers from fever, usually larger amounts of moisture occur. Due to the usually restless sleep and the resulting movements, however, there is an increased moisture output at the same time, so that the bed climate is regulated or stabilized within acceptable limits.
  • the breathable zones are not above the user, disturbing temperature and pressure gradients are avoided. It is therefore prevented that the body of the user is partially cooled. Further, the breathable zones are not covered by the body of the user, so that the air exchange is not hindered.
  • Preferably snake-shaped or narrow rectangular configured breathable zones are provided on both sides of the area, which is above the expected position of the body of the user, so that only a small and uniform, for the user quite pleasant heat flow can result.
  • the breathable zones are through the first and / or the second textile layer; or alternatively covered by the first and / or the second textile layer and at least one heat-insulating third textile layer; so that disturbing air movements and isolation gaps are avoided.
  • the breathable zones provided inside and / or outside the body region can be locked, so that an adaptation of the blanket to the seasonal climatic conditions is possible.
  • individual end pieces can be provided, which can be fastened by means of Velcro fasteners, buttons or zippers on the edges of the breathable zones.
  • Velcro fasteners buttons or zippers
  • this causes a considerable effort, especially when installing the individual end caps.
  • the storage of the individual end caps is rather unvorteilhaftrealisierbar.
  • two mutually complementary cover parts which can be connected to one another by means of seams, Velcro fastenings, buttons or zippers are provided, of which the first is provided with the breathable zones and the second with correspondingly arranged end pieces.
  • the two ceiling parts can therefore be rapidly connected or separated from one another in the manner of LEGO® building blocks.
  • the storage of the complementary first or second ceiling part is much easier than the storage of the individual end caps.
  • Particularly advantageous in this solution is also that three types of duvets can be realized. For example, in summer only the first ceiling part provided with the breathable zones can be used. In the transitional periods, in spring and autumn, the light second end piece provided with the end pieces can be used and in winter the combination of both ceiling parts is used. Furthermore, if necessary, the two ceiling parts can also be used separately. It is possible to use two parts of the ceiling which are only partially complementary to one another, during the connection of which the breathable zones are not or only partially filled.
  • the distinctly hydrophilic second textile layer can be a single-layered or multi-layered, coarse-meshed, fine-meshed or microporous fabric, a knitted fabric, a knitted fabric or a non-woven fabric made of chemical and / or natural fibers.
  • Advantageously usable for example, cotton, nylon or polyamide.
  • Synthetic textiles including nonwovens, have been greatly improved in recent times, so that their properties have closely approximated those of natural products, such as cotton. Synthetic textiles also have a high degree of variability, which makes it possible to optimize the fabric for the present application. Synthetic textiles also have good mechanical strength in terms of abrasion, tearing and tearing, high breathability, isotropic properties (equally resilient in all directions with the advantages of traditional fabrics and knitted fabrics), a textile feel, good drape and a high ease of use.
  • Mites and allergen-dense second textile layers with a maximum pore size of 0.5 ⁇ m are preferably used which have pronounced hydrophilic properties and at the same time prevent the ingress of mites.
  • the blanket consists of several parts, preferably a ceiling middle part, which is connected or connected by means of connecting devices, such as zippers, on one or both sides with ceiling side panels.
  • the breathable zones for the regulation of the bed climate can be provided in the ceiling middle part or in the ceiling side parts.
  • the breathable zones are preferably provided eccentrically, so that each ceiling side panel in a first and a second textile layer is connectable to the ceiling middle part, provided it is on both sides corresponding parts of Having connecting device. Users with a larger body circumference can therefore mount the ceiling side parts in such a way that a larger distance between the breathable zones results. For narrower users or quieter sleepers, a smaller distance between the openings may be preferable.
  • the connecting devices are preferably covered by insulating flaps, so that they can not rest directly on the body of the user and can form disturbing thermal bridges.
  • the insulating tabs are preferably connected to the ceiling middle part, so that they are facing away from the user, directed to the outside. It is possible to use one or more walls, optionally filled with insulating insulation laps, which are arranged on one or both sides of the blanket, the connecting devices preferably completely cover and optionally enclose annular.
  • insulating laps are preferably provided on both sides of the ceiling side parts, so that it is prevented that parts of the connecting device can be exposed.
  • each duvet is provided with two mutually interchangeable ceiling middle parts, by means of which the user can adjust the blanket to the respective needs, such as the health status, and possibly depending on the season room conditions.
  • FIG. 1 shows the structure of a cover blanket 1A according to the invention, which has a filling 10 consisting for example of down, hydrophobic or weakly hydrophilic first textile layers 11, 12 adjoining it on both sides and markedly hydrophilic second textile layers 13, 14 adjacent thereto.
  • a filling 10 consisting for example of down, hydrophobic or weakly hydrophilic first textile layers 11, 12 adjoining it on both sides and markedly hydrophilic second textile layers 13, 14 adjacent thereto.
  • the transfer of moisture from top to bottom, ie starting from the upper second textile layer 13 is described, which is applied to the user when using the blanket (see FIG. 5 ).
  • the substances used for the first textile layers 11, 12 are not absolutely hydrophobic, but relatively hydrophobic in relation to the fabrics of the second textile layers 13, 14.
  • the upper second textile layer 13 of FIG. 1 which consists of a single or multi-layered hydrophilic fabric or laminate, water drops are shown, which are absorbed by the hydrophilic second textile layer 13 and distributed flat along the fibers of the fabric or laminate.
  • the provided under the hydrophilic second textile layer 13 relatively hydrophobic first textile layer 11 prevents that larger amounts of moisture locally enter the hydrophilic filling 10 and strongly moisten the down there, which affect their properties during use and then make a longer venting or drying necessary , As in FIG. 1 shown, the moisture or water vapor is then distributed with greatly reduced density on the relatively hydrophobic first textile layer 11 and can penetrate through the numerous channels or pores and capillaries 111 provided therein and into the hydrophilic filling 10.
  • a hydrophilic third textile layer 15 is fixedly or detachably connected to the first or second textile layer 11 or 13.
  • the first and second textile layers 11, 13 and 12, 14 are detachably connected to each other or form, firmly joined together, a laminate, as in FIG. 3 is shown.
  • FIG. 3 further shows the construction of a duvet 1B, which has two breathable zones 3, in which no filling 10 is provided. If stronger air movements occur in these areas, the water vapor is thereby rapidly led to the outside.
  • These breathable zones 3 are preferably located outside the area 4, which is above the expected position of the body of the user. For example, the breathable zones 3 are placed in the outer thirds or quarters of the blanket. This prevents the breathable zones 3 from being covered by the body of the user, thereby obstructing the air exchange.
  • the peripheral arrangement of the breathable zones 3 also avoids disturbing temperature gradients that occur because the insulation properties of the blanket in the area of the breathable zones is changed, the user's body is exposed to barely perceptible air currents and moisture evaporates on the user's skin or clothing can.
  • breathable zones 3 are bounded laterally by the filling 10, which is trapped for example by means of the sewn together upper and lower first textile layers 11, 12. Above and / or below the breathable zone 3 is covered by means of the first and / or the second textile layer 11, 12 or 13, 14 and optionally with an insulating third textile layer 15, through which the insulation value of the blanket in the breathable zones 3 largely is kept constant.
  • the breathable zones 3 are covered on both sides by the first and second textile layers 11, 13 and 12, 14.
  • the breathable zones 3 are covered on both sides by the hydrophilic second textile layer 13 and a hydrophilic, breathable third textile layer 15.
  • FIG. 5 shows the over a symbolically illustrated user designed duvet 1A with a ceiling center part 1A 'and ceiling side panels 1A''on.
  • the textile layers 11, ..., 15 of the ceiling middle part 1A ' are shown cut open.
  • Shown is also a seam 18, by means of which the two relatively hydrophobic first textile layers 11, 12 are connected to one another. Further, a linen cover 99 is shown.
  • the duvet 1A is therefore separable into individual parts, which can be easily stored in a washing machine and washed, which is particularly important in the use of hydrophilic substances.
  • FIG. 6 shows the blanket 1B with the hydrophilic second textile layer 13, which is disposed within the area 4, which lies above the expected position of the body of the user and on both sides outside this area 4 lying breathable zones covered 3, Also shown is an insulating third textile layer 15 ' which only covers the breathable zones 3 and harmonizes the insulation properties. The moisture is therefore removed from the body area of the user and discharged laterally over the breathable zones 3.
  • a closure piece 3 ' is shown by means of which one of the breathable zones 3 can be locked.
  • the end piece 3 ' can be used individually, or be provided on a ceiling part 1B', which is connectable at its edges, for example by means of zipper or Velcro closures with the ceiling part 1B, so that the two ceiling parts 1B, 1B 'one above the other or next to each other.
  • FIG. 7 shows the duvet 1A with a ceiling middle part 1A ', which is connected on both sides by means of zippers 2 with two cover side parts 1A'', 1A "'
  • the zippers 21 consisting of two parts 21, 22 are covered by insulating tabs 7, the two sides are arranged on the ceiling side parts 1A '', 1A '''and connected to one another at their ends, so that they receive the associated zip fastener 2 in a pocket-like manner and surround it in a ring-like manner
  • Ceiling middle part 1A 'replaceable which has a different room climate adapted insulation properties.
  • the breathable zones 3 are arranged eccentrically, so that these, depending on the mounting of the ceiling side parts 1A '', 1A '' ', more or less spaced apart and thus adapted to the needs, possibly the body dimensions of the user can.
  • the insulating tabs 7 are provided on both sides of the ceiling side parts 1A ", 1A" ', causes the zippers 2 are always reliably covered.
  • the bed cover can be extended to a four-part cover by means of the additional ceiling middle part 1A', provided the ceiling side parts 1A ", 1A '' 'are provided on one side only with a portion 22 of the zipper 2, the insulating tabs 7 are preferably only on the central part 1 A' provided.
  • the inventive blanket has been described and illustrated in preferred embodiments. On the basis of the teaching according to the invention, however, further expert designs can be realized. Especially Different dimensions of the duvet and the ceiling parts can be selected. Furthermore, various natural and synthetic substances and filling materials can be used. Furthermore, any other shapes and dimensions of the breathable zones 3 can be realized. It is also possible to use differently configured, possibly interlocking, filled or unfilled Isolierlappen.
