Abstract
A down covering is subdivided in individual longitudinal or transverse webs (2). The longitudinal webs (2) are detachably linked to each other along their longitudinal edges (6) by means of fastening devices (3) such as zippers, snap fasteners, laces, buttons and button holes or closers of the touch-and-close type. The seams (4) may be insulated with insulating flaps or beads (5) which completely overlap the seams (4). The insulating flaps or beads (5) may be filled with insulating material (11), in the same way as the webs (2). Different insulating materials (11) may be used, such as down, feathers, natural fibres or synthetic materials. A
down covering having any desired combination of longitudinal or transverse webs (2) with different heat insulating strengths may thus be playfully assembled.

Description
21~192 EIDERDOWNS THAT CAN BE PUT TOGETHER OR TAKEN APART INTO
COMPONENT PARTS
An idPal eiderdown should have the following characteristics:
In order for there to be an optimum hygiene in bed, it would ~e desirable that the eiderdown could be washed without any problem in a standard household washing machine. This is particularly important for persons, who are allergic to domestic ~ites. By regular laundering, the particles triggering the allergy (the allergenes) can be removed. The conventional eiderdowns are too large to be laundered in a household washing machine. They have to be sent to an appropriately equipped laundry for cleaning.
An ideal eiderdown has to be able to ~e adapted to the changing requirements with respect to size and thermal insulation.
It would, for example, be very practical if one could split-up a large eiderdown of a double ~ed into two smaller eiderdowns for a single bed when required or if one could enlarge a small eiderdown of a single bed, so that it could:be used for a Fr:ench bed. The conventional eiderdowns cannot ~e enlarge~ or r4duced in size just like that. ~ ~
It would equally be desirable if in the case of eiderdowns for double beds or French beds the degre of thermal ihsulation could be adapted to the individual requirements o~ each sleeper. Not all persons are equally susceptible to cold. Therefore often there is the re~uirement to have the degree of thermal insulation on the side of one of the sleepers smaller or:larger than on the side of the other sleeper. Conventional eiderdowns have the same degree of insulation over their whole sur~ace area. Individual:
reguirements of the sleepers can therefcre not be accommodated. For this reason, in:a double bed at least one of the two sleepers is su~3ected~to temperatures, which:he experiences as unpleasant.
Furtherm~re, th~ degree of thermal insulation of an eiderdow~~,should b~ able to be adapted to the temperature differenc~ resulting from the changing s~asonsO During wintertime, an eiderdown should provide a high deg~Pe of thermal in~ulation, during spring and autumn a medium degree of ther~al insulation and in sum~ertime a low degree of t~ermal insula~îon. The degree o~ thermal insulation of conventional eiderdowns cannot be chanqed.
This, however, signifies, that one needs a separate eiderdown for each of the three seasonal tempera~ure periods, in order to always achieve an optimum temperature in bed.
For this reason, one was in ssarch of an eiderdown, which - 2 ~ 21131~2 can ~e laundered in a con~entional domestic washing machine, the size of which can be changed and the degree of thermal insulation of which c~n be adapted to the re~uirements of th~ individual sleepers. In accordance with today's state of the art, the following solutions for this exist:
Various eiderdowns were proposed, which, while their degree of thermal insulation can be changed, could, however, neither be washed in a domestic washing machine nor changed in size.
In the patent specification FR 2 45~ 257 (date of publication 05.06.1979), for ~xample, an eiderdown was proposed, which is composed of several individual covers, which are placed one upon the other and ~astened together~ ~hile with this the degree of thermal insula*ion can be chan~ed, all the other problems remain unsolved. Similar solutions with the same disadvantages have also ~een described in the patent specifications US
4903 361 (date of publication 24.10.1g84) and GB 2211 731 (date of pu~lication 12~07.19&9)~
Subject of the invention in the patent specification EP
0127 912 (date of pu~lication 24.10.1984) is an eiderdown~
which is composed of at least two combinable single person aiderdowns. With this~ the deg~ee of:thermal insulation can in double ~eds be adapted to the requirements of the individual sleepers. Single person eiderdowns are, however, too large for laundering in domestîc washing machines. This eiderdown moreover has the disadvantage, that the edges, on:which the single person eiderdowns are joined together, overlap and that:thus thic~, unpleasant bulges are produced.
A further solution was proposed in the patent specification GB 2176 998 (date of pùblication 14~01~1987)o In the case of that invention, an eiderdown for a double bed is con~erned, which:has at least one : :
slit, which extends in longitudinal direction of the eiderdown from the edge of the eiderdown at the head end in the direction of the edge of the eiderdown at the~foot :~
endO:The slit is equipped with a closing mechanism. When required~ the slit can be opened and a part of the eiderdown can be flipped over to the side. While also with this ei~er~own the de~ree of thermal insulation can be adapted to the individual requirements of the sleepers all other problems, however, still remain unsolved.
Eiderdowns have also been described, with which both the pro~lem of the adjustable degree of thermal insulation as well as the problem of laundering in domestic washing ~achines have been able to be solved. These eiderdowms, however, maniest other essential disadvantages.
.
Thus, for example, in the patent specification FX 2595 228 (date of publication 11.09.1987) an eid~rdown was described, which comprises a cover made of many adjoining, ~1131~2 rectangular bags of the same shape and the same size. Each bad is provided wi~h an opening, through which a rectangular pillow can be inserted into the bag.
A similar eiderdown was also proposed in the patent specification (US 4839 934~.
These eiderdowns havP the advantage, that the pillow can be removed from the cover prior to launderin~. One can without any problem separately launder the pillows and the covers in a domestic washing machine. For the various pillows it is possible to use differently insulating fill material. ~y an appropriate distribution ~f the differently insulating pillows within the e;derdown, the degree of thermal insulation can be optimally adapted to the requirements of the sleepers.
An essential disadvantage of these eiderdowns is, that the body is separated from the insulating material tfeather down, feathers) by two layers of cloth (cover,pillow) and that as a result the humidity dissipation is obstructed.
It has moreover ~ecome ~anifest in practice, that the pillows dislodge the~selves within the cover and that by this an unpleasant unevenness and cold spots are produced.
A further solution was described in the patent specification WO 90/14036 (date of publication 29.11.1g90). The invention there concerns a feather down - or feather eiderdown, which is c~mposed of several individual, interchangeable bags. All bags are similar in shape and size. Each ~ad is bordered by a joinin~ device, such as, for example, zippers, buttons, press-buttons, etc. The individual ~ags are :joined together not unly ~y their longitudinal sides but also by ~heir lateral sides.
~his means, that many saams are for~ed and that within the eiderdown four corners of bags can come together.
This is one of the essential disadvantages of this eiderdown, because the many seams running through the eiderdown both longitudinally and in transverse form many uninsulated zones, through which heat can escape. That is to say, no special insulating provisions are foreseen along the edges of the bagsO Those points, where four corners of ~ags come together, are also a problem. There the tharmal insulation is missing over a larger surface area. Apart from thls, relatively hiyh tensile forces can act on t~e'corners, when the sleeper moves. It is questi~nable, whether the joining de~ice can withstand these forces~ Therefore the ~iderdown will not pr~ve itself in practice.
The invention puts itself the task of finding an eiderdown, which can be laundered in a conventional domestic washing machine, the size of which can be changed and the degree of thermal insulation of which can be adapted to the requirements of the individual sleepers.
The eiderd~wn should moreover not have any uninsulated seams.
211:~192 The problem is according to the invention solved with the help of the characteristic features in accordance with the characterizing part of the claim for patent 1.
The invention concerns an eiderdown, which is split-up into individual longitudinal - or transverse widths. the longitudinal and transverse widths are joined togekher along their longitudinal edges with the help of joining - devices, which can be released again. The seams are preferably insulated with insulating flaps. The invention is inter alia explained in the drawings. Shown are:

:
When transverse widths are used, the length of the transverse width has to be selected corresponding to the width of the ~ed. The length of the eiderdown 1 is determined by the nu~ber of transverse widths, which are coupled together.
In order for the longitudinal - or transverse widths 2 being able to ~e coupled together, they are equipped with joining devices 3 along their longitudinal edges 6. As joining devires 3, preferably foreseen are'for example plastic zippars, press-buttons, tapes for tying, buttons with ~utton holes, velGro fasteners or others. It is necessary to utilize zippers, both sides of which can be completely separated from one another.
If buttons are selected, then on the one longitudinal ed~e 6 a ~utton hole tape is stitched on and on the other longitudinal edge 6 a row of buttons i5 affixed.
The longitudinal edges 6 of two adjoining longitudinal -or transverse widths 2 can eithe~ be joined together by an individual joining device 3 (refer to Figs. 4 to 8) or else by two joining devices 3 running parallel to one another (refer to Figs. 9 to 13). In the latter case, the two joining devices 3 are connected together by a tape shaped bridge 12.
The seams 4 in the case of a preferred version are insulated with insulating ~laps or pads 5. For the execution and arrangement of the insulating flaps 5 J
various possibilities are foreseen.
Thus, for example, along a longitudinal edge 6 of each longitudinal - or transverse width 2 a ring shaped insulating flap 5 can be~located, which borders the complete joining device 3 (refer to Figs. 4, 5 and 8). It extends ~rom the first transverse edge 7 of the longitudinal - or transverse width 2 above the joining device 3 along the longitudinal edge ~ to the other transverse edge 7 of the longitudinal - or transverse width~ There it is bent around by 180 deg and therefore forms a sort of pocket 8. It then extends underneath the joining device 3 further along the longitudinal edge 6 ~ac~ to the first transverse edge 7 and is there also bent over by 180 deg. If two parallel joining devices 3 are used, then~the insulating flap 5 ~orders both joining devices 3 including the bridge 12 (refer to Figs. 9 and A ring shaped insulating flap 5 is preferably made out of a single longish width of cloth 13. The length of this width of cloth 13 corresponds approximately to the length of the longitudinal - or transverse width 2 of an eiderdown 1. The width of cloth 13 is folded several times along its longitudinal direction, so that two closed hollows are formed, which correspond to the internal hollows 9 of thP insulating flap. The folded width of cloth 13 is stitched on with at least three seams 14, 15 2:1131~32 to a longitudinal - or transverse width 2 of an eiderdown 1. In the Figures 14 to 16 three possible methods of folding a width of cloth 13 are represented.
In the case of the first method of folding (Fig. 14), the inner zone 18 of the width of cloth 13 forms the lateral face 19 of a longitudinal - or transverse width of an eiderdown. This lateral face 19 is bent inwards. The width of cloth 13 is stitched together along its longitudinal edges 23. Its cross section is therefore ring shaped. The longitudinal - or transverse width 2 is formed ~y a piece of cloth 16, which is folded longitudinally in the ~iddle. The two free longitudinal edges 17 of this piece of cloth 16 thus lie one a~ove the other. They ar~ :
stitched onto the width of cloth 13 above, resp., :
underneath the inner zone 18. These two outer seams 14 thus border the side face 19 of the longitudinal - or transverse width 2. The outer zone 20 of the width of cloth 13 is f~lded longitudinally inwards in the middle in such a manner, that the folded seam 21 touches the longitudinal dividing line of the inner zone 18. By this, two enclosed hollows are for~ed, the inner hollows 9 of the insulating flap 5. ~etween the two inner hollows 9 an intermediate space 22 is formed, which is closed to the inside and open to the outside. In this intermediate space 22 one half of the zipper 3 is arranged in such a way, that its teeth face outwards and its inner edge touches the folded seam 21 of the outer zone 20. SinGe at this point the outer.and the inner zone of the width of cloth 13 touch, the zipper 3 as well as the inner and the outer zone of the width of cloth 13 can ~e fastened together by a single longitudinal seam 15.
:
In the case of the second method of folding (refer to ~ig.
15), the side face 19 of a:longitudinal - or transverse width 2 is formed by the piece of cloth 16, of which the rest of the width 2 consists. The two longitudinal edges 17 of the piece of cloth 16 are turned over inwards and stitched together with the longitudinal edges 23 of the width of ~loth 13. The outer zone 20 of the width of cloth 13 is folded inwards in the middle in such a manner, that the folded seam 21 is ~lush:with the longitudinal edges 17, 23 of the piece of cloth 16, resp., the width of cloth 13. By this, two c~osed insulating ~lap inner h~llows ~
,are also.formed, and between these an inter~ediate space 22, which,is open to the outside and clo~ed to the inside. In this:intermediate space 22, one half of the zipper 3 is arranged in such a manner, that the teeth of the zipper face outwards and its inner edge touches the folded seam 21 of the ~uter zone 20. The folded seam 21 of the outer zone 20, the inner edge of the zipper 3 and the longitudinal ~dges 17, 23 of the piece of cloth, resp~, of the width of cloth 13 are joined together by a single se m 15.
In the case of the third method of folding trefer to ~ig.
16), the inner zone 18 of the width of cloth 13 is folded longitudinally along the middle. The fre~ longitudinal .. . .
edges 17 of the piece of cloth 16 are stitched to the folded seam 24. The outer zone 20 of the width of cloth 13 here consists of two parts of equal size, each with a free longitudinal edge 23~ Both these parts are folded towards thQ middle and inside in such a manner, that the free longitudinal edges 23 touch the folded seam 24 of the inner zone 1~. Through this, once again two insulating inner hollows 9 are formed. Between these inner hollows an intermediate space 22 is formed, which is~open to ~he outside and closed to the inside by the fo~ded seam 24 of the inner zone 18. In this intermediate space 22, one half of a zipper 3 is arranged in such a manner, that the teeth of the zipper face outwards and that its inner ~dge touches the folded seam 24 of the inner zone 18. The folded seam 24, the inner edge of the zipper 3 and the longitudinal edges 17, 23 of the piece of cloth 16, resp., the width of cloth 13 are joined together with a single seam 15.
Both in the case of the second as well as the third ~ethod of folding, a further seam 14 in each case additionally fastens the width of cloth 13 above, resp., underneath its inner zone 18 to the piece of cloth 16 of the longitudinal - or transverse width 2. The two seams 14 form the longitudinal edges of the side faces 19 of ~he longitudinal - or transverse width.
The second half of the zipper 3 is fastened to the longitudinal side, which fa~es away from the insulating flap 5, as follows: The piece of cloth 16 is folded in~ards on this longitudinal side in longitudinal directio in such a manner, that a kind of longitudinal slit is formed. The second half of the zipper 3 is arranged in this longitudinal slit in such a way, that the zipper teeth face outwards and that its inner edge touches the folded seam facing inwards~ The half of the zipper 3 is fastened to those parts of the piece of clo~h 16, which form the walls of the slit, by a seam 26.
In the case of a second version of the insulating flap 5, on each of the two longitudinal edges 6 of a longitudinal - or transverse width 2 an insulating flap 5 i5 located.
In doing so, one of the insulating flaps 5 is located above the joining device, resp~, joining devices 3 and the other below this, resp., these. The insulating flaps 5 also extend along the joining devices 3 and can be bent over ~y 180 deg on one o~ their ends. If two longitudinal -, resp., transverse widths 2 are coupled together, ~hen al~ays one insulating flap 5, whi~h lies above the jvining device, resp., joining devices 3 meets an insulating flap 5, which lies underneath this, resp., these (refer to Figs. 7 and 11).
In the case of a closed joining device 3, the insulating flaps 5 overlap the seams all around. The seams 4 are thus optimally insulated. The joining device 3 is also completely covered. Any unpleasant contact with the bodies of the sleepers is thus prevented.
When using two parallPl joining devices 3, the possibility of arranging an insulating flap 5 between the two joining devices 3 is conceivable. Each of the longitudinal -, resp., transverse widths 2 then has such an insulating flap 5 on one of its longitudinal -, resp., transverse widths 2 ~refer to Fig. 13). The insulating flaps 5 can be ~ade with double walls. ~hey then have an inner hollow 9. This inner hollow 9 is connected to the inner hollow 1~ of the lon~itudinalO resp., trans~erse width 2 and is also filled with insulating material 11. ~s a result, these pad shaped insulating flaps 5 obtain a degree of thermal insulation.
But the possi~ility also exists of using insulating flaps 5 made of cloth, which are not filled with insulating material (re~er to Figs. ~ and 12). Their degree of thermal insulation is correspondingly lower.
~urthermore, there al~o exists the possibility of doing without insulating flaps 5 (refer to Figs 9 and 10).
The longitudinal, resp., trans~erse widths 2 can ~e filled with various insulating materials 11. Conceivable as insulating materials are for example feather down, feathers, natural fibres, synthetic materials or others.
The degree of filling of the various longitudinal -, resp., transverse wîdths can be different.
An eiderdown can be assembled from differently filled longitudinal -, resp., transverse widths 2. Since heavily fi~led longitudinal -, resp., transverse widths 2 insulate better than lightly filled ones, the degree of thermal insulation along the width of the eiderdown, resp., length of the eiderdown can be varied. It is conceivable, for example, that in the case ~f a four7width eiderdown 1 for the summertime, two lightly filled longitudinal widths 2 can ~e taken in the middle and two heavily filled ones on the outside.:In wintertime, however, one can take the two heavily filled ones in the middle and the two lightly filled ones on the outside. One can also c~mbine differently filled longitudinal widths 2 in such a ~anner, that one side of a double eiderdown consists ~nly of strongly insulating, the other side, however, only of weakly insulating longitudinal widths 2.
There is-f~rther~ore the possibility of co~bining the eiderdown alternately:out of a strongly - and a weakly insu1ating ~ongitudinal -, respO, transverse width 2.
Many varia~ions for combining an eiderdown 1 are possible. Differently ~illed longitudinal - or transverse widths 2 can be combined as desired.
It is evident, that every eiderd~wn 1 can also be converted into a sleeping bag by joining together the outer longitudinal edges 6 of the eiderdown 1.
~he longitudinal -, resp., transverse widths can have 211~1.t3~
saddle stitched seams. In the ~igures 1, 2 and 3, squares are shown as subdivisions. But as shapP for the saddle stitched seams, also circles, smaller strips ~r others are conceivable. The saddle stitched sea~s can also be omitted or supplemented by tucks 25.
The proposed eiderdown has essential advantages in :
comparison with the eiderdowns kn~wn to date~
Contrary to conventional eiderdowns, the proposed eiderdown 1 can thanks to its possibility of being taken apart into longitudinal -, resp., transverse widths 2 be laundered in a conventional domestic washing ~achine. In comparison ~o the eiderdowns that can be taken apart known up to now, as described for example in the patent speci~ication WO 90/14036, the proposed eiderdown 1 has the great advantage, that all seams are thermally insulated. Moreover, within the proposed eiderdown 1 there are no spots, where corners of the individual elements, of which the eiderdo~n is composed, come together~ There~ore it is assured, that the individual elements are n~t torn apart by mechanical influences.
In comparison with those eiderdowns with interchangeable insulating pillows, as described for example in patent ~pecification F~ 259~ 228 and US 4839 934, the proposed eiderdown has the great advantage, that between the skin of the sleeper and the insulating material 11, in particular the feather down~ there is only a single layer of cloth~ Therefore the dissipation of water vapo~r is not o~structed and the sleeper experiences a pleasant, dry feeling o~ warmth. Moreover, the insulating material 11 is fixed in the relatively narrow longitudinal -, resp, transverse widths 2. Any dislodging of the insulating ~aterial is thus significantly reduced. In the case of those eiderdowns with in~erchangeable insulating pillows, it in contrast often occurred, that the insulating pillows slid out of the bags. The arrangement into longitudinal wid~hs ~ ~oreover in the case of the proposed eiderdown 1 leads to a high degree o~ stability of shape.
.
In contrast to the eiderdowns known up until now, in which the degree of insulation can be changed by placing se~eral individual eiderdowns one above the other, the proposed eiderdown 1 has the advantage~ that i~ can be taken apart into longitudinal -, resp., transverse widths 2 arranged next to one another. Thus it on the one hand is possible to launder the proposed eiderdown 1 in a conve~tional domestic washing mac~ine, on ~he other hand the degree of thermal insulation can be freely varied, by replacing strongly insulating longitudinal -, resp., transverse widths 2 by weakly insulating longitudinal -, resp., transverse widths 2 or vice versa. Because of the possibility of combining differently filled widths 2, an eiderdown in line with the climate can be made up at any time, which can also be adapted to all seasons. In 21131~
addition, one by this also achieves the possi~ility of each sleeper being able to put together an eiderdown, which corresponds to his individual requirements. A hot sleeper, who always perspires, will, for example, select one of the less insulating widths 2, and a cold sleeper, who is always too cold, will rather select more strongly insulating widths 2. It is not only possible to adapt the overall degree of thermal insulation of the eiderdown, but also to select different degrees of thermal insulation for various zones of the eiderdown 1. In the case of eiderdowns for dou~le beds, it is therefore possi~le to take into account the requirements of warmth of both sleepers.
The proposed eiderdown 1 is very interesting for the modern housewife, sin~e it can be laundered in a domestic washing machine and therefore there always exists an optimum hygiene in the bed. Because of this ease of laundering, the proposed eiderdown 1 is particularly suita~le for those persons, who are allergic to h~useho~d dust mites.
Since the joining seams and thus also the joining devices 3 are completely covered with insulating flaps 5, the proposed eiderdown 1 is very good on the skin. It feels cuddly, easy to sleep in and soft.

COMPONENT PARTS
An idPal eiderdown should have the following characteristics:
In order for there to be an optimum hygiene in bed, it would ~e desirable that the eiderdown could be washed without any problem in a standard household washing machine. This is particularly important for persons, who are allergic to domestic ~ites. By regular laundering, the particles triggering the allergy (the allergenes) can be removed. The conventional eiderdowns are too large to be laundered in a household washing machine. They have to be sent to an appropriately equipped laundry for cleaning.
An ideal eiderdown has to be able to ~e adapted to the changing requirements with respect to size and thermal insulation.
It would, for example, be very practical if one could split-up a large eiderdown of a double ~ed into two smaller eiderdowns for a single bed when required or if one could enlarge a small eiderdown of a single bed, so that it could:be used for a Fr:ench bed. The conventional eiderdowns cannot ~e enlarge~ or r4duced in size just like that. ~ ~
It would equally be desirable if in the case of eiderdowns for double beds or French beds the degre of thermal ihsulation could be adapted to the individual requirements o~ each sleeper. Not all persons are equally susceptible to cold. Therefore often there is the re~uirement to have the degree of thermal insulation on the side of one of the sleepers smaller or:larger than on the side of the other sleeper. Conventional eiderdowns have the same degree of insulation over their whole sur~ace area. Individual:
reguirements of the sleepers can therefcre not be accommodated. For this reason, in:a double bed at least one of the two sleepers is su~3ected~to temperatures, which:he experiences as unpleasant.
Furtherm~re, th~ degree of thermal insulation of an eiderdow~~,should b~ able to be adapted to the temperature differenc~ resulting from the changing s~asonsO During wintertime, an eiderdown should provide a high deg~Pe of thermal in~ulation, during spring and autumn a medium degree of ther~al insulation and in sum~ertime a low degree of t~ermal insula~îon. The degree o~ thermal insulation of conventional eiderdowns cannot be chanqed.
This, however, signifies, that one needs a separate eiderdown for each of the three seasonal tempera~ure periods, in order to always achieve an optimum temperature in bed.
For this reason, one was in ssarch of an eiderdown, which - 2 ~ 21131~2 can ~e laundered in a con~entional domestic washing machine, the size of which can be changed and the degree of thermal insulation of which c~n be adapted to the re~uirements of th~ individual sleepers. In accordance with today's state of the art, the following solutions for this exist:
Various eiderdowns were proposed, which, while their degree of thermal insulation can be changed, could, however, neither be washed in a domestic washing machine nor changed in size.
In the patent specification FR 2 45~ 257 (date of publication 05.06.1979), for ~xample, an eiderdown was proposed, which is composed of several individual covers, which are placed one upon the other and ~astened together~ ~hile with this the degree of thermal insula*ion can be chan~ed, all the other problems remain unsolved. Similar solutions with the same disadvantages have also ~een described in the patent specifications US
4903 361 (date of publication 24.10.1g84) and GB 2211 731 (date of pu~lication 12~07.19&9)~
Subject of the invention in the patent specification EP
0127 912 (date of pu~lication 24.10.1984) is an eiderdown~
which is composed of at least two combinable single person aiderdowns. With this~ the deg~ee of:thermal insulation can in double ~eds be adapted to the requirements of the individual sleepers. Single person eiderdowns are, however, too large for laundering in domestîc washing machines. This eiderdown moreover has the disadvantage, that the edges, on:which the single person eiderdowns are joined together, overlap and that:thus thic~, unpleasant bulges are produced.
A further solution was proposed in the patent specification GB 2176 998 (date of pùblication 14~01~1987)o In the case of that invention, an eiderdown for a double bed is con~erned, which:has at least one : :
slit, which extends in longitudinal direction of the eiderdown from the edge of the eiderdown at the head end in the direction of the edge of the eiderdown at the~foot :~
endO:The slit is equipped with a closing mechanism. When required~ the slit can be opened and a part of the eiderdown can be flipped over to the side. While also with this ei~er~own the de~ree of thermal insulation can be adapted to the individual requirements of the sleepers all other problems, however, still remain unsolved.
Eiderdowns have also been described, with which both the pro~lem of the adjustable degree of thermal insulation as well as the problem of laundering in domestic washing ~achines have been able to be solved. These eiderdowms, however, maniest other essential disadvantages.
.
Thus, for example, in the patent specification FX 2595 228 (date of publication 11.09.1987) an eid~rdown was described, which comprises a cover made of many adjoining, ~1131~2 rectangular bags of the same shape and the same size. Each bad is provided wi~h an opening, through which a rectangular pillow can be inserted into the bag.
A similar eiderdown was also proposed in the patent specification (US 4839 934~.
These eiderdowns havP the advantage, that the pillow can be removed from the cover prior to launderin~. One can without any problem separately launder the pillows and the covers in a domestic washing machine. For the various pillows it is possible to use differently insulating fill material. ~y an appropriate distribution ~f the differently insulating pillows within the e;derdown, the degree of thermal insulation can be optimally adapted to the requirements of the sleepers.
An essential disadvantage of these eiderdowns is, that the body is separated from the insulating material tfeather down, feathers) by two layers of cloth (cover,pillow) and that as a result the humidity dissipation is obstructed.
It has moreover ~ecome ~anifest in practice, that the pillows dislodge the~selves within the cover and that by this an unpleasant unevenness and cold spots are produced.
A further solution was described in the patent specification WO 90/14036 (date of publication 29.11.1g90). The invention there concerns a feather down - or feather eiderdown, which is c~mposed of several individual, interchangeable bags. All bags are similar in shape and size. Each ~ad is bordered by a joinin~ device, such as, for example, zippers, buttons, press-buttons, etc. The individual ~ags are :joined together not unly ~y their longitudinal sides but also by ~heir lateral sides.
~his means, that many saams are for~ed and that within the eiderdown four corners of bags can come together.
This is one of the essential disadvantages of this eiderdown, because the many seams running through the eiderdown both longitudinally and in transverse form many uninsulated zones, through which heat can escape. That is to say, no special insulating provisions are foreseen along the edges of the bagsO Those points, where four corners of ~ags come together, are also a problem. There the tharmal insulation is missing over a larger surface area. Apart from thls, relatively hiyh tensile forces can act on t~e'corners, when the sleeper moves. It is questi~nable, whether the joining de~ice can withstand these forces~ Therefore the ~iderdown will not pr~ve itself in practice.
The invention puts itself the task of finding an eiderdown, which can be laundered in a conventional domestic washing machine, the size of which can be changed and the degree of thermal insulation of which can be adapted to the requirements of the individual sleepers.
The eiderd~wn should moreover not have any uninsulated seams.
211:~192 The problem is according to the invention solved with the help of the characteristic features in accordance with the characterizing part of the claim for patent 1.
The invention concerns an eiderdown, which is split-up into individual longitudinal - or transverse widths. the longitudinal and transverse widths are joined togekher along their longitudinal edges with the help of joining - devices, which can be released again. The seams are preferably insulated with insulating flaps. The invention is inter alia explained in the drawings. Shown are:

One longitudinal~width 2 is about:40 to 50 centimetres : ~:
:wide.~By~coupling three or four:longitudinal widths 2, one:thus obtains an eiderdown:for a sin;gle bed. If one : ~ :adds:an addi~ional longitudinal width:2, an eiderdown for a French bed is:produced. The eiderdown 1 can~be extended ~: as required in width.
:
When transverse widths are used, the length of the transverse width has to be selected corresponding to the width of the ~ed. The length of the eiderdown 1 is determined by the nu~ber of transverse widths, which are coupled together.
In order for the longitudinal - or transverse widths 2 being able to ~e coupled together, they are equipped with joining devices 3 along their longitudinal edges 6. As joining devires 3, preferably foreseen are'for example plastic zippars, press-buttons, tapes for tying, buttons with ~utton holes, velGro fasteners or others. It is necessary to utilize zippers, both sides of which can be completely separated from one another.
If buttons are selected, then on the one longitudinal ed~e 6 a ~utton hole tape is stitched on and on the other longitudinal edge 6 a row of buttons i5 affixed.
The longitudinal edges 6 of two adjoining longitudinal -or transverse widths 2 can eithe~ be joined together by an individual joining device 3 (refer to Figs. 4 to 8) or else by two joining devices 3 running parallel to one another (refer to Figs. 9 to 13). In the latter case, the two joining devices 3 are connected together by a tape shaped bridge 12.
The seams 4 in the case of a preferred version are insulated with insulating ~laps or pads 5. For the execution and arrangement of the insulating flaps 5 J
various possibilities are foreseen.
Thus, for example, along a longitudinal edge 6 of each longitudinal - or transverse width 2 a ring shaped insulating flap 5 can be~located, which borders the complete joining device 3 (refer to Figs. 4, 5 and 8). It extends ~rom the first transverse edge 7 of the longitudinal - or transverse width 2 above the joining device 3 along the longitudinal edge ~ to the other transverse edge 7 of the longitudinal - or transverse width~ There it is bent around by 180 deg and therefore forms a sort of pocket 8. It then extends underneath the joining device 3 further along the longitudinal edge 6 ~ac~ to the first transverse edge 7 and is there also bent over by 180 deg. If two parallel joining devices 3 are used, then~the insulating flap 5 ~orders both joining devices 3 including the bridge 12 (refer to Figs. 9 and A ring shaped insulating flap 5 is preferably made out of a single longish width of cloth 13. The length of this width of cloth 13 corresponds approximately to the length of the longitudinal - or transverse width 2 of an eiderdown 1. The width of cloth 13 is folded several times along its longitudinal direction, so that two closed hollows are formed, which correspond to the internal hollows 9 of thP insulating flap. The folded width of cloth 13 is stitched on with at least three seams 14, 15 2:1131~32 to a longitudinal - or transverse width 2 of an eiderdown 1. In the Figures 14 to 16 three possible methods of folding a width of cloth 13 are represented.
In the case of the first method of folding (Fig. 14), the inner zone 18 of the width of cloth 13 forms the lateral face 19 of a longitudinal - or transverse width of an eiderdown. This lateral face 19 is bent inwards. The width of cloth 13 is stitched together along its longitudinal edges 23. Its cross section is therefore ring shaped. The longitudinal - or transverse width 2 is formed ~y a piece of cloth 16, which is folded longitudinally in the ~iddle. The two free longitudinal edges 17 of this piece of cloth 16 thus lie one a~ove the other. They ar~ :
stitched onto the width of cloth 13 above, resp., :
underneath the inner zone 18. These two outer seams 14 thus border the side face 19 of the longitudinal - or transverse width 2. The outer zone 20 of the width of cloth 13 is f~lded longitudinally inwards in the middle in such a manner, that the folded seam 21 touches the longitudinal dividing line of the inner zone 18. By this, two enclosed hollows are for~ed, the inner hollows 9 of the insulating flap 5. ~etween the two inner hollows 9 an intermediate space 22 is formed, which is closed to the inside and open to the outside. In this intermediate space 22 one half of the zipper 3 is arranged in such a way, that its teeth face outwards and its inner edge touches the folded seam 21 of the outer zone 20. SinGe at this point the outer.and the inner zone of the width of cloth 13 touch, the zipper 3 as well as the inner and the outer zone of the width of cloth 13 can ~e fastened together by a single longitudinal seam 15.
:
In the case of the second method of folding (refer to ~ig.
15), the side face 19 of a:longitudinal - or transverse width 2 is formed by the piece of cloth 16, of which the rest of the width 2 consists. The two longitudinal edges 17 of the piece of cloth 16 are turned over inwards and stitched together with the longitudinal edges 23 of the width of ~loth 13. The outer zone 20 of the width of cloth 13 is folded inwards in the middle in such a manner, that the folded seam 21 is ~lush:with the longitudinal edges 17, 23 of the piece of cloth 16, resp., the width of cloth 13. By this, two c~osed insulating ~lap inner h~llows ~
,are also.formed, and between these an inter~ediate space 22, which,is open to the outside and clo~ed to the inside. In this:intermediate space 22, one half of the zipper 3 is arranged in such a manner, that the teeth of the zipper face outwards and its inner edge touches the folded seam 21 of the ~uter zone 20. The folded seam 21 of the outer zone 20, the inner edge of the zipper 3 and the longitudinal ~dges 17, 23 of the piece of cloth, resp~, of the width of cloth 13 are joined together by a single se m 15.
In the case of the third method of folding trefer to ~ig.
16), the inner zone 18 of the width of cloth 13 is folded longitudinally along the middle. The fre~ longitudinal .. . .
edges 17 of the piece of cloth 16 are stitched to the folded seam 24. The outer zone 20 of the width of cloth 13 here consists of two parts of equal size, each with a free longitudinal edge 23~ Both these parts are folded towards thQ middle and inside in such a manner, that the free longitudinal edges 23 touch the folded seam 24 of the inner zone 1~. Through this, once again two insulating inner hollows 9 are formed. Between these inner hollows an intermediate space 22 is formed, which is~open to ~he outside and closed to the inside by the fo~ded seam 24 of the inner zone 18. In this intermediate space 22, one half of a zipper 3 is arranged in such a manner, that the teeth of the zipper face outwards and that its inner ~dge touches the folded seam 24 of the inner zone 18. The folded seam 24, the inner edge of the zipper 3 and the longitudinal edges 17, 23 of the piece of cloth 16, resp., the width of cloth 13 are joined together with a single seam 15.
Both in the case of the second as well as the third ~ethod of folding, a further seam 14 in each case additionally fastens the width of cloth 13 above, resp., underneath its inner zone 18 to the piece of cloth 16 of the longitudinal - or transverse width 2. The two seams 14 form the longitudinal edges of the side faces 19 of ~he longitudinal - or transverse width.
The second half of the zipper 3 is fastened to the longitudinal side, which fa~es away from the insulating flap 5, as follows: The piece of cloth 16 is folded in~ards on this longitudinal side in longitudinal directio in such a manner, that a kind of longitudinal slit is formed. The second half of the zipper 3 is arranged in this longitudinal slit in such a way, that the zipper teeth face outwards and that its inner edge touches the folded seam facing inwards~ The half of the zipper 3 is fastened to those parts of the piece of clo~h 16, which form the walls of the slit, by a seam 26.
In the case of a second version of the insulating flap 5, on each of the two longitudinal edges 6 of a longitudinal - or transverse width 2 an insulating flap 5 i5 located.
In doing so, one of the insulating flaps 5 is located above the joining device, resp~, joining devices 3 and the other below this, resp., these. The insulating flaps 5 also extend along the joining devices 3 and can be bent over ~y 180 deg on one o~ their ends. If two longitudinal -, resp., transverse widths 2 are coupled together, ~hen al~ays one insulating flap 5, whi~h lies above the jvining device, resp., joining devices 3 meets an insulating flap 5, which lies underneath this, resp., these (refer to Figs. 7 and 11).
In the case of a closed joining device 3, the insulating flaps 5 overlap the seams all around. The seams 4 are thus optimally insulated. The joining device 3 is also completely covered. Any unpleasant contact with the bodies of the sleepers is thus prevented.
When using two parallPl joining devices 3, the possibility of arranging an insulating flap 5 between the two joining devices 3 is conceivable. Each of the longitudinal -, resp., transverse widths 2 then has such an insulating flap 5 on one of its longitudinal -, resp., transverse widths 2 ~refer to Fig. 13). The insulating flaps 5 can be ~ade with double walls. ~hey then have an inner hollow 9. This inner hollow 9 is connected to the inner hollow 1~ of the lon~itudinalO resp., trans~erse width 2 and is also filled with insulating material 11. ~s a result, these pad shaped insulating flaps 5 obtain a degree of thermal insulation.
But the possi~ility also exists of using insulating flaps 5 made of cloth, which are not filled with insulating material (re~er to Figs. ~ and 12). Their degree of thermal insulation is correspondingly lower.
~urthermore, there al~o exists the possibility of doing without insulating flaps 5 (refer to Figs 9 and 10).
The longitudinal, resp., trans~erse widths 2 can ~e filled with various insulating materials 11. Conceivable as insulating materials are for example feather down, feathers, natural fibres, synthetic materials or others.
The degree of filling of the various longitudinal -, resp., transverse wîdths can be different.
An eiderdown can be assembled from differently filled longitudinal -, resp., transverse widths 2. Since heavily fi~led longitudinal -, resp., transverse widths 2 insulate better than lightly filled ones, the degree of thermal insulation along the width of the eiderdown, resp., length of the eiderdown can be varied. It is conceivable, for example, that in the case ~f a four7width eiderdown 1 for the summertime, two lightly filled longitudinal widths 2 can ~e taken in the middle and two heavily filled ones on the outside.:In wintertime, however, one can take the two heavily filled ones in the middle and the two lightly filled ones on the outside. One can also c~mbine differently filled longitudinal widths 2 in such a ~anner, that one side of a double eiderdown consists ~nly of strongly insulating, the other side, however, only of weakly insulating longitudinal widths 2.
There is-f~rther~ore the possibility of co~bining the eiderdown alternately:out of a strongly - and a weakly insu1ating ~ongitudinal -, respO, transverse width 2.
Many varia~ions for combining an eiderdown 1 are possible. Differently ~illed longitudinal - or transverse widths 2 can be combined as desired.
It is evident, that every eiderd~wn 1 can also be converted into a sleeping bag by joining together the outer longitudinal edges 6 of the eiderdown 1.
~he longitudinal -, resp., transverse widths can have 211~1.t3~
saddle stitched seams. In the ~igures 1, 2 and 3, squares are shown as subdivisions. But as shapP for the saddle stitched seams, also circles, smaller strips ~r others are conceivable. The saddle stitched sea~s can also be omitted or supplemented by tucks 25.
The proposed eiderdown has essential advantages in :
comparison with the eiderdowns kn~wn to date~
Contrary to conventional eiderdowns, the proposed eiderdown 1 can thanks to its possibility of being taken apart into longitudinal -, resp., transverse widths 2 be laundered in a conventional domestic washing ~achine. In comparison ~o the eiderdowns that can be taken apart known up to now, as described for example in the patent speci~ication WO 90/14036, the proposed eiderdown 1 has the great advantage, that all seams are thermally insulated. Moreover, within the proposed eiderdown 1 there are no spots, where corners of the individual elements, of which the eiderdo~n is composed, come together~ There~ore it is assured, that the individual elements are n~t torn apart by mechanical influences.
In comparison with those eiderdowns with interchangeable insulating pillows, as described for example in patent ~pecification F~ 259~ 228 and US 4839 934, the proposed eiderdown has the great advantage, that between the skin of the sleeper and the insulating material 11, in particular the feather down~ there is only a single layer of cloth~ Therefore the dissipation of water vapo~r is not o~structed and the sleeper experiences a pleasant, dry feeling o~ warmth. Moreover, the insulating material 11 is fixed in the relatively narrow longitudinal -, resp, transverse widths 2. Any dislodging of the insulating ~aterial is thus significantly reduced. In the case of those eiderdowns with in~erchangeable insulating pillows, it in contrast often occurred, that the insulating pillows slid out of the bags. The arrangement into longitudinal wid~hs ~ ~oreover in the case of the proposed eiderdown 1 leads to a high degree o~ stability of shape.
.
In contrast to the eiderdowns known up until now, in which the degree of insulation can be changed by placing se~eral individual eiderdowns one above the other, the proposed eiderdown 1 has the advantage~ that i~ can be taken apart into longitudinal -, resp., transverse widths 2 arranged next to one another. Thus it on the one hand is possible to launder the proposed eiderdown 1 in a conve~tional domestic washing mac~ine, on ~he other hand the degree of thermal insulation can be freely varied, by replacing strongly insulating longitudinal -, resp., transverse widths 2 by weakly insulating longitudinal -, resp., transverse widths 2 or vice versa. Because of the possibility of combining differently filled widths 2, an eiderdown in line with the climate can be made up at any time, which can also be adapted to all seasons. In 21131~
addition, one by this also achieves the possi~ility of each sleeper being able to put together an eiderdown, which corresponds to his individual requirements. A hot sleeper, who always perspires, will, for example, select one of the less insulating widths 2, and a cold sleeper, who is always too cold, will rather select more strongly insulating widths 2. It is not only possible to adapt the overall degree of thermal insulation of the eiderdown, but also to select different degrees of thermal insulation for various zones of the eiderdown 1. In the case of eiderdowns for dou~le beds, it is therefore possi~le to take into account the requirements of warmth of both sleepers.
The proposed eiderdown 1 is very interesting for the modern housewife, sin~e it can be laundered in a domestic washing machine and therefore there always exists an optimum hygiene in the bed. Because of this ease of laundering, the proposed eiderdown 1 is particularly suita~le for those persons, who are allergic to h~useho~d dust mites.
Since the joining seams and thus also the joining devices 3 are completely covered with insulating flaps 5, the proposed eiderdown 1 is very good on the skin. It feels cuddly, easy to sleep in and soft.
