Description

The invention relates to a blanket, in particular down or feather blanket. The cover has a first plate and a second plate, wherein the two plates are connected to a transverse seam and a longitudinal seam to form a cavity. The cavity is divided by the longitudinal seam and the transverse seam into a plurality of first chambers and second chambers. The first chamber is filled with a first filler and the second chamber with a second filler.

Blankets are mostly used for sleeping as a body pad and / or body pad. Especially as a body pad, blankets serve to warm the sleeping person and at the same time to carry off the moisture due to the transpiration of the sleeping person.

There are a variety of different types of covers for this purpose. In the following, reference is made in particular to the quilt and the quilt. In such blankets, the blanket is divided into a plurality of cassettes, the cassettes being filled with down or feathers or fibers or natural or animal hairs. Although such coverings offer a very good thermal insulation, but it is disadvantageous that the exchange of air and the removal of moisture is limited. This has the consequence that for the sleeping an unpleasant sleeping climate, due to the warm and humid air under the blanket, sets. Consequently, a restless sleep results, resulting in an insufficient recovery effect for the sleeper. Furthermore, there is the danger Covering during sleep, so that the sleeping person cools down so that he gets a cold. In addition, there is a removal of moisture over the filling, so that the filler clumps over time.

Out EP 1 499 221 B1 goes out a blanket, which is provided with a plurality of ventilation openings, via which a removal of heat and moisture takes place. The blanket has a flexible layer formed from a top panel and a bottom panel which incorporates down, fiber or natural hair or animal hair filling, the layer being perforated with a plurality of ventilation apertures each spanned by separate net screens. However, the cover is disadvantageous in that due to the mesh grid, the cover is expensive to manufacture. In addition, the blanket nestles due to the mesh grid worse to the contour of a sleeper, so that the sleeping comfort is limited.

Fig. 1 shows as down or feather blanket 1 designed blanket, as it is mainly used as a summer blanket.

The down or quilt 1 comprises a first panel 10 and a second panel 11 made of a flexible material such as tight-weave cotton or silk or cellulose fibers or a blend of the aforementioned materials. The first plate 10 and the second plate 11 are arranged congruently one above the other and connected by means of transverse seams 13 and longitudinal seams 14 such that a cavity 17 is formed.

According to the Fig. 1 and 2 the cavity 17 is subdivided by a plurality of transverse seams 13 extending in the transverse direction x and longitudinal seams 14 extending orthogonal to the transverse direction x in the longitudinal direction y into a plurality of first chambers 18 of equal size. Here, the first plate 10 and the second plate 11 pierced by the transverse seams 13 and the longitudinal seams 14, so that the first chambers 18 are separated from each other. Such a down or feather blanket 1 is referred to as a quilt. The first chambers 18 are filled with a first filler 12, which are down and / or feathers. As a result of the separation of the first chambers 18, slippage of the first filler 12 is counteracted. According to Fig. 1 the cavity 17 is divided by the transverse seams 13 and longitudinal seams 14 in the transverse direction x into six first chambers 18 and in the longitudinal direction y into eight first chambers 18.

As in the Fig. 1 and 3 is shown, the transverse seams 13 between two longitudinal seams 14 each have two first portions 15 and a second portion 16. The second section 16 defines a second chamber 22. The second chamber 22 is filled with a second filler 23. In the present exemplary embodiment, the second filler 23 is air, although another suitable filler would also be conceivable. The second chamber 22 delimiting portion 16 is located in the transverse direction x symmetrical to the first portion 15 and is separated by the transverse seam 13 of the first chamber 18. Die erste Kammer 15 ist in der Querrichtung x durch den Quersehrungsabschnitt 13 angeordnet. The second section 16 is according to Fig. 1 circular, but may also be elliptical, polygonal, in particular square or rectangular. In the present embodiment, the diameter D of the second chamber 22 is about 7 cm and the total number of the second chambers 22 is 42. The ratio of the area F _{1 of} the first chamber 18 to the area F _{2 of} the second chamber 22 is about 15: 1 In addition, the ratio of the total area F of the down or feather ceiling 1 to the sum of the areas F _{2 of} all the second chambers 22 is approximately 17: 1. The second chamber 22 dissipates the heat prevailing under the down or feather ceiling 1 Moisture, so that a pleasant sleeping climate is generated.

In the 4 to 6 another embodiment of the down or feather blanket 1 is shown, which differs from the first embodiment in that that the number of second chambers 22 is reduced. The down or feather blanket 1 according to Fig. 4 has 30 second chambers 22. The diameter D is 10 cm and is thus larger than that of the first embodiment. The down or feather blanket 1 according to Fig. 4 has five first chambers 18 in the transverse direction x and seven first chambers 18 in the longitudinal direction y. The ratio of the area F _{1 of} the first chamber 18 to the area F _{2 of} the second chamber 22 is approximately 10: 1. In addition, the ratio of the total area F of the down or feather ceiling 1 to the sum of the areas F _{2 of} all the second chambers 22 is 22 18: 1. In addition, the two plates 10, 11 are connected by a web processing. Accordingly, a down or feather blanket 1 according to the 4 to 6 referred to as a bridge ceiling. Such a down or feather blanket 1 is mainly used as a transitional cover from the warm to the cold season or vice versa their application.

In the FIGS. 7 and 8 is schematically illustrated the web processing. According to Fig. 7 is attached to the first plate 10, an approximately C-shaped first web 19, which has a height H ₁ . The first web 19 is connected via the transverse seam 13 or longitudinal seam 14 with the first plate 10. On the second plate 11, an approximately C-shaped second web 20 by means of the opposite transverse seam 13 or longitudinal seam 14 is attached, which has a height H ₂ . As in Fig. 8 is shown, the two webs 19, 20 are connected to each other via a connecting seam 21, so that both webs have an overall height H. The first chambers 18 formed thereby are referred to as cassettes and receive the first filler. The cassettes prevent slippage of the first filler 12 within the cavity 17. In addition, the webs 19, 20 serve to avoid cold spots.

On the 4 to 6 Coming back, this means for the second embodiment of the down or feather blanket 1, that the first chamber 18 and the second chamber 22 not from the transverse seams 13 and longitudinal seams 14th alone, but additionally by the webs 19, 20. The total height H of the first web 19 and the second web 20 is about 2 cm.

In the Fig. 9 to 11 Another embodiment of the down or feather blanket 1 is disclosed. The down or feather blanket 1 according to Fig. 9 to 11 differs from the previous embodiments in that the down or feather cover 1 for dividing the cavity 17 in first chambers 18 has only two longitudinal seams 14, wherein between the two longitudinal seams 14 two second portions 16 and three first portions 15 are arranged. The down or feather blanket 1 has according to Fig. 9 three first chambers 18 in the transverse direction x and six first chambers 18 in the longitudinal direction y. As a result, a larger central area is formed, which ensures good conformability to the sleeping and thus leads to a good thermal insulation. The diameter D of the second chamber 22 is about 10 cm. The ratio of the area F _{1 of} the first chamber 18 to the area F _{2 of} the second chamber 22 is approximately 15: 1. In addition, the ratio of the total area F of the down or feather ceiling 1 to the sum of the areas F _{2 of} all the second chambers 22 12: 1. Furthermore, the embodiment differs according to the Fig. 9 to 11 from the previous embodiment in that the total height H of the first web 19 and the second web 20 is greater. The total height H of the webs 19, 20 according to the third embodiment is about 4 cm. Thus, the third embodiment is used in particular as a winter blanket due to the larger volume of the first chamber 18, which consequently can accommodate a larger amount of the first filler 12. In addition, the middle section with the two second sections 16 and three first sections 15 allows a particularly high conformability of the down or feather cover 1 to the sleeping person.

In all three embodiments, the transverse seam 13 extends in the transverse direction x and the longitudinal seam 14 in the longitudinal direction y, which is orthogonal to the transverse direction x. Furthermore, the ratio of the first section 15 to second section 16 between two longitudinal seams 14 in the transverse direction y between about 2: 1 and about 4: 1, preferably about 3: 1.

The down or feather cover 1 is characterized in that due to the large number of second chambers 22, which are filled with air, a removal of moisture and heat is ensured, so that a comfortable sleeping comfort is ensured due to effective ventilation. Furthermore, the introduced in the first chambers 18 filler 12 provides good thermal insulation. The fact that the second chamber 22 is limited only by the transverse seam 13 and is arranged between two longitudinal seams 14 results in improved conformability of the down or feather blanket 1 on the sleeping person.
