Abstract

Par son bord d'ouverture (23) et la bande de rembourrage annulaire (3) placée à l'intérieur contre celui-ci, un sac pour les bras (2) fait saillie dans le bord d'ouverture (13) d'un sac inférieur (1); sur son pan supérieur (22) est appliqué de manière fixe ou détachable un couvre-tête (4). A partir du bord d'ouverture (13) du sac inférieur (1), le bord d'ouverture (43) du couvre-tête présente un écartement modifiable (b). Les pans inférieurs (11 et 21) des deux sacs (1, 2) peuvent être fixés l'un à l'autre. Alors que le sac (1) et le sac (2) peuvent avoir la même largeur, le couvre-tête (4) est plus étroit et peut être raccordé de manière fixe ou détachable au sac pour les bras par le bord d'ouverture (43) de son pan inférieur (41). Il est ainsi possible d'étendre commodément un bras sur le rembourrage d'appui (31) du bord d'ouverture (23) dans le sac pour les bras et de poser la tête sur le rembourrage de coussin (32) à partir de (23) sur ce bras, alors que l'autre bras pend par exemple dans le dos. La position de sommeil peut ainsi être déterminée sans contrainte grâce à cette grande liberté de mouvement, tout comme la largeur d'ouverture (b) réglant l'aération intérieure. De cette manière sont permises une détente et une récupération rapides, ainsi qu'une position du corps confortable et stable.By its opening edge (23) and the annular padding strip (3) placed inside against it, a bag for the arms (2) projects into the opening edge (13) of a lower bag (1); on its upper panel (22) is fixedly or detachably applied a head cover (4). From the opening edge (13) of the lower bag (1), the opening edge (43) of the head cover has a modifiable spacing (b). The lower sides (11 and 21) of the two bags (1, 2) can be fixed to each other. While the bag (1) and the bag (2) can have the same width, the head cover (4) is narrower and can be fixedly or detachably connected to the bag for the arms by the opening edge ( 43) of its lower panel (41). It is thus possible to conveniently extend an arm on the support padding (31) of the opening edge (23) in the bag for the arms and to lay the head on the cushion padding (32) from ( 23) on this arm, while the other arm hangs, for example, in the back. The sleeping position can thus be determined without constraint thanks to this great freedom of movement, just like the opening width (b) regulating the interior ventilation. This allows rapid relaxation and recovery, as well as a comfortable and stable body position.

Description

Sleeping bag

The invention relates to a sleeping bag with a lower bag enclosing the body, to the upper slip opening of which, at least in the area of the support sheet, an enveloping bag protrudes toward the head end.

Sleeping bags of this type are known in various designs. The higher the temperatures to be endured, the more completely the external closure is chosen. The "slip opening" is then, especially in the case of so-called "mummy sleeping bags", often only one breathing opening, which moreover can be closed to a greater or lesser extent. Although sleeping bags with different widths are offered, as a rule the interior is kept so narrow that the position and posture within the sleeping bag can hardly be changed, but rather is rolled over with the bag. A hood that is sometimes connected to the hatch opening is dimensioned accordingly.

This figure-hugging design is particularly pronounced where the arms are in special sleeves. The hands are usually free and often have to be protected, but a free mobility cannot be achieved in this way, so that there is no sufficient relaxation and depletion. When spending the night outdoors or in tents, the rest time available for relaxation is generally very limited and often follows great physical exertion. It is therefore important to enable sleeping or at least rest in such a way that the best possible relaxation and recovery can be achieved in the shortest possible time. This presupposes that one takes the most relaxing posture and can change his position even during the rest period, for example, can switch from one side to the other. However, the sleeping bag may not be taken as a whole, but the resting person should be able to freely change his posture within the sleeping bag as required.

Known sleeping bags usually end close to the hatch opening, usually with the hood attached there. Arms and hands must therefore be oriented downwards if they are not to protrude from the hatch opening. This downward orientation is quite pronounced in sleeping bags with attached sleeves.

Laborious deformations of the sleeping bag parts are necessary if the upper arm alone is to be adjusted slightly towards the head. These deformations are all the greater when the arm is extended to the head or beyond the head. The arms also protrude from the hand openings. Otherwise, the cooling is much stronger if one has to bring an arm out of the slip opening because of the better sleeping position.

This cooling of individual parts of the body leads to discomfort: even after falling asleep, controlled by the subconscious, one constantly turns from one to the other, often very unfavorable position. As a result, the lungs are pressed and can only work with difficulty due to the position, which impairs the activity of the heart. Due to the uncontrolled squeeze see limb blood circulation is additionally prevents be¬, sometimes even interrupted _^, resulting in turn to further Weg¬. This is often associated with cold processes. Real relaxation and recreation cannot be achieved in this way.

Det from studies in the Indian culture, generally E.ing «ιn τ _f in the _f ^ Snnitfttswcr.on ofundon hnben, has herausgebil- for optimal relaxation approximately the following position: a) lateral position, b) the lower leg is at an angle pulled to the body, the upper leg lies on the lower so that there is only slight pressure. c) The lower arm is extended over the head. d) The head lies comfortably on the biceps, e) the arm above hangs behind the back.

Here, the angled lower leg, additionally supported by the upper leg, leads to a very stable posture, the lungs being free of pressure and the heart working lightly and being able to supply all zones of the body with blood. You cannot snore in the side position, and there is no pressure on any organs important for the supply, stomach, intestines and the like.

The advantage of this sleeping position is a particularly quick relaxation. The degree of recovery is therefore very high even if the situation is changed consciously or unconsciously at some point during sleep.

It is also not essential to extend your lower arm fully. Even if he is kept so free that he can support the head or protrude a little above the head, an increased degree of recovery is achieved, whereby 1 later the full power can be used again.

Whether with conventional sleeping bags, in bed or on a bed, stretching out the arm always brings a cooling down, which in turn can lead to sleep disorders or sleep interruptions at low ambient temperatures.

10 The object of the invention is therefore to design a sleeping bag so that it allows any suitable sleeping position, in particular with the arm stretched out, while warming the whole body and thus enables rapid relaxation and recovery. _ _

! 5

The solution to this problem, starting from the sleeping bag defined at the outset, is that the envelope bag is designed as an arm bag that has at least the length of an arm that extends beyond the head and on the head

20 plug opening a headrest is attached.

Instead of a smaller envelope bag, usually designed as a hood, a spacious arm bag is provided here, which opposes one another from the area of the slip opening

25 extends to the lower sack in such a way that it permits any sleeping position recognized as advantageous, in particular sleeping with the arm extended. The head can rest on the upper arm, and the sleeping conditions do not change significantly even with the rest position, for example if you change the 0 side, stretch out completely, or "stretch" with your arms stretched or the head pads depending on your body ¬ perlage changed in relation to the sleeping bag. The relative arrangement of the head to the slip opening can also be changed, which is primarily intended to establish the breathing connection to the ambient air 5 and to ensure this function in any position and assignment to the body, in particular to the nose and mouth. continuous One does not feel packaged or tied up in a sleeping bag, but feels it as a tent-like dwelling in which one withdraws. The degree of closure to the outside is related to the type of design in the area of the slip opening, that is, between the lower bag and the arm bag. There, of course, the same things can be provided as with conventional sleeping bags, for example a hood, means for changing the width of the slip opening such as a cord lacing and zippers on the slip opening and on the side seam.

Noteworthy additional effort usually only arises with high-quality, thick-walled sleeping bags for outdoor use. In closed rooms, the sleeping bag can be made of much thinner material, such as a beaver bedding material or the like, which does not require any significant additional expenditure.

Details and further embodiments of the invention are set out in the subclaims and are shown in the schematic drawing, for example. Show it:

1 shows a spatial representation of a sleeping bag according to the invention, FIG. 2 shows a longitudinal view of an optimal design of this sleeping bag FIG. 3 shows a ³³ composed of several parts ^,

4 ^, a spatial representation of the individual parts of the sleeping bag according to FIG. 3, FIG. 5 a blank sheet for producing a modified embodiment of the invention, and FIGS. 6-10 longitudinal sections for further modified sleeping bag designs. - According to FIGS. 1 to. 1 is the lower sack, 2 the arm sack, 3 is an annular padded strip attached to the inside of the edge of the arm sack and. a head bag in the manner of an enlarged hood.

The lower bag 1 has approximately the same width over its entire length and is primarily formed by a lower web 11 and an upper web 12, which are each separately connected at two of their three edges. One of these connections can be made by a zipper, which can also be attached to the top.

The arm bag 2 has approximately the same width as the lower bag 1. Its lower web 21 and its upper web 22 are in turn connected to one another at two of their three edges. Since a side opening is practically out of the question, the edges are usually sewn. At the opening edge 23 of the plug-in opening, the annular cushion strip 3 is provided within the arm bag 2, which in its simplest form can consist of foam and is generally fixed on the inside of the arm bag 2.

For use, the arm bag 2 is inserted with its opening edge 23 into the opening edge 13 of the lower bag 1 by the width a. The basic two-part sleeping bag is now functional. It goes without saying that the two bags 1 and 2 with the overlap width a are normally firmly connected to their lower webs 11 and 21.

The head cover. is designed like a hood and tapers from its opening edge .3 to the closed end. Lower web .1 and upper web .2 are already narrower than arm bag 2 at the base of opening .3. The hood-like head cover is expedient. attached to the upper web 22 of the arm bag in a suitable manner. It is sufficient if the lower web .1 is connected to the opening edge .3. The top web 52 is expediently designed to be dimensionally stable in such a way that it maintains its curvature even when it is not supported from the inside by the head.

Between the opening edges 13 and. .3 a gap-like slip opening 5 with the width b is then formed. This slip opening does not have to cover the entire width of the head cover. extend, it can also be narrowed again by covering the gap, for example a cord can be pulled through the upper parts of the opening edges 3 and 13 in order to be able to adapt the opening to the respective requirement. ^"•

The sleeping bag user can enter through the slip opening 5 or through a side or top opening, he can, as shown in FIGS. 1 and 2, take any suitable sleeping position, in particular an arm through the cushion strip 3 into the arm bag 2 stuck. Since the biceps rests on the support pad 31, the head rests on the upper web 22 of the ^• Armsackes and the head cushion pad 32 on the biceps, and in the outset leg position of the right arm is hanging freely down behind the back. The shoulder lies against the opening edge 23 of the arm bag and thus also against the edge of the head cushion 32.

Like the arm bag, the pillow cushion is largely deformable, so that the head can be extended more or less from the opening edge 13 of the foot bag by stretching or the like. When you freeze, you pull your head back, when you need more air, you stretch it outwards. The entire body is enclosed by portions of the sleeping bag, and the interior of the arm bag 2 is only in a labyrinthine manner along the upper web parts of the opening edges 13 and 23 in connection with the ambient air. Therefore auc 'i arm bag always maintains a temperature which largely corresponds to the temperature in the lower bag 1, despite the lower heat emission by the one arm. This is further favored by the fact that the head cover. forms a buffer space to the atmosphere and also improves the external insulation above the arm bag. In principle, this buffer space can also be extended over the entire arm bag.

What is more important than additional insulation is that the greatest possible range of movement is provided within the arm bag 2 in order to be able to assume any desired stretched position. In any case, with the relaxation position shown in FIGS. 1 and 2, largely constant blood flow is achieved during rest and possibly sleep. The arm does not necessarily have to be fully extended, it can also be angled if you support the head over the two cushions and an inserted arm and change the lateral position in the meantime.

5 shows in a spatial representation the simplified manufacture of a sleeping bag according to the invention from a single blank 6 with bottom web β1 and top web 62, which are folded together according to the arrow bend 6 and connected at three edges, a partial connection with an opening closure such as a zipper or the like can be occupied. The slip opening 5 or another access opening is then formed into the upper web 62 between the lower sack and the upper sack, and the cushioning strip 3 can be held by a pocket which is held by a transverse cover strip 65. This is attached to the web blank with an edge and can be turned over according to arrows 66.

In the sleeping bag made in this way, the opening edges of the foot sack and arm bag end in the same place, which would cancel out the desired labyrinth effect, but would in any case reduce it. 6, the ring-shaped cushion strip 3 can therefore be connected with the outer end of its pillow cushion 32 at the end part of the top web 22 of the arm bag 2 in such a way that the cuff-shaped cushion strip projects into the lower bag 1. It is overlapped by the free end of the upper web 12 when it is connected to the arm bag 2 over its entire length.

7, a web for the lower bag and arm bag can be laid in the longitudinal direction, so that one would only have to bind at the longitudinal edges 7. The overlap of the upper tracks 12 and '22 can then be chosen at will, regardless of how the cushion strip 3 is formed and attached. If possible, it should be attached in a detachable manner so that it can be cleaned separately. Instead of foam with / or without a cover, any other suitable type of pillow can be used, for example an annular fabric tube with down filling.

According to FIG. 8, such a cushion strip 3 is attached in a ring pocket 71, the edges of which are closed by a Velcro fastener 72. There is also connected 73 7 with its outer end outside of the topsheet 22 and the head cover only a cover sheet, wherein between the opening edges 13 and .3 ^{sterstreifens'} 3, for example, again slit-like slip opening 5 is formed above about the middle of the Pol¬. In this way, a sensitive scalp is then better covered without the fresh air supply being impeded. Here, too, the cover sheet 73 can be provided stiffened in order to be able to insert the head into the opening provided as required.

9 differs from the one described above in that at least a part 221 of the upper io -

web 22 is brought down under the pillow cushion 32 of the cushion strip 3 and is connected from below through the Velcro fastener 72 to the cushion strip. In this way, the upholstery strip immediately forms the headrest and can be removed and cleaned as needed without any Au towels.

This also applies to the embodiment shown in FIG. 10, where the support pad 31 is fastened on the lower web 21 of the arm bag 2 by the Velcro fastener 72 and the free edge part 221 of the upper web 22 takes over the function of the head cover. In principle, the pillow cushion 32 can be provided independently of the top web 22. -

To better shield the interior of the arm bag, however, it may be advisable to provide a sealing connection at the contact point 77. Since this connection must be detachable in any case, it can take over the fastening function alone with a suitable design as a line fastener such as zippers, clamp fasteners and the like, so that the Velcro fastener 72 or the like can be omitted here. The point 77 is also so favorable that it can not cause any disruptive pressure. Since you can adjust the cross-section of the slip opening 5 by means of a cord 78 or the like as required, in principle you can do without any attachment of the cushion strip 3, so you can adjust this strip accordingly regardless of the sleeping bag of the respective sleeping position. The padded strip can also be designed so that it closes all around with respect to the end part of the arm bag.
