Definitions
- the present invention relates to a sleeping bag comprising at least one insulating layer containing a thermal insulating material and surrounding a sleeping area in a closed state of the sleeping bag.
- sleeping bags should have an insulating effect as well as possible against the environment in order to protect a sleeper from environmental influences, above all cold. Therefore, in principle, the aim is to create the best possible space for the sleeping area.
- Most sleeping bags therefore have a sleeping area surrounded by one or more insulation layers, which at best leaves at least an opening for the head of a sleeper, at least in the closed state.
- the insulating layer has or the insulating layers have chambers which are provided with a heat-insulating material, e.g. Down or synthetic fibers with good bulkiness, are filled.
- the insulating layer encloses the sleeping area, wherein it should be ensured that the heat-insulating material avoid direct thermal bridges between the sleeping area and the surroundings as far as possible.
- the sleeping bag should therefore be cut so short that this amount of air is as low as possible and the heat development of the body is used as efficiently as possible.
- a sleeping bag comprising at least one containing a thermally insulating material and in a closed state of the sleeping bag surrounding a sleeping insulating layer, wherein the insulating layer is arranged in at least one adjustment such that in a closed state of the sleeping bag by a on the inside of the sleeping area surrounding insulating layer exerted outward force of the sleeping area is increased, and wherein at least one band of elastic material is provided, which holds two mutually remote areas of the insulating layer in the adjustment such that when enlarging the of the insulating surrounded sleeping area, the band undergoes elastic stretching and thereby generates a the insulating layer in its initial position repatriating force.
- the inventive arrangement of insulating layer and elastic band makes it possible that the sleeping bag can be stretched from the inside in its width, without insulation losses due to direct thermal contact under Avoiding the heat-insulating material between the sleeping area and the environment occur.
- the material required for the expansion of the sleeping area is provided by the insulating layer, which is equipped with a "material reserve" in the adjustment area.
- the magnitude of the expansion is not determined by the insulating layer, but rather is determined by the elastic elongation of the tape. Accordingly, the elastic band allows by its arrangement on the insulating layer, an improved adaptation of the same to the body of the sleeper.
- the band which holds the insulating layer in the adjustment, is elastic, it provides for a self-expansion for a restoring force, which returns the insulating layer back to its original position as soon as through the body of the sleeper from the inside, ie from the sleeping area ago the insulating layer exerts pressure exerted.
- the expansion of the insulating layer in the adjustment range always only goes as far as required by the current body position of the sleeper, and can be completely different for different locations of the insulating layer.
- the sleeping area therefore always has an optimal shape after each movement of the sleeper and adapts automatically to the movements of the body. With all these changes, the sleeping area always remains equally reliably enclosed by the insulating layer. Without forces acting from the sleeping area, ie at rest, the insulating layer always assumes a predefined position of origin.
- the sleeping area in the Usrprungsposition ie in the closed state of the sleeping bag and without a force exerted on the inside of the insulating layer, the form of an elongated cavity with a longitudinal axis of the human body extending longitudinal axis, the insulating layer - seen in a Cross-section orthogonal to the longitudinal axis - completely surrounds the sleeping area and the adjustment allows an increase in the size of the sleeping area formed by the insulating layer.
- the insulating layer in the adjustment is superimposed or / and folded together, wherein the elastic band overlap sections and / or adjacent wrinkles of the insulating layer interconnects.
- overlapping sections should be understood to mean superimposed or superimposed sections of the insulating layer. This is intended in particular to include all sections which, from the point of view of an imaginary center of the sleeping area, do not lie completely next to one another in a radial direction outwards, but cover one another, ie are arranged one behind the other.
- the elastic band then has a predetermined overlap width in the unstretched state. The overlap width thus determines the maximum possible widening of the sleeping area.
- Wrinkles are those areas where the insulating layer between two fold edges forms a bulge inwardly or outwardly.
- the maximum possible extension of the sleeping area by a fold is given by the greater length of the insulating layer extending along the bulge than the distance between the fold edges in the original position. The closer to a given bulge the fold edges in the original position, i. in the unstretched state of the elastic band, abut each other, the more the sleeping area can expand, until finally all the wrinkles have disappeared.
- the insulating layer may have portions in the adjustment, which abut each other in the unstretched state of the elastic band and slide upon exposure of an outwardly directed force on the inside of the insulating layer with increasing stretching of the elastic band to each other.
- These sections preferably extend substantially in the circumferential direction of the insulating layer arranged around the sleeping area, so that a pressure exerted by the sleeping area on the inner surface of the insulating layer directly leads to an expansion of the sleeping area at the point in question.
- the insulating layer is formed by a pocket filled with a heat-insulating material, which is rolled up around a longitudinal axis to form the sleeping area and whose longitudinal edges, which run parallel to the direction of the longitudinal axis, are connected to one another so that an elongated cavity is formed which forms the sleeping area.
- adjacent to the longitudinal edges of the pocket adjacent areas to form the adjustment range can be arranged overlapping each other and held together by the elastic band. Since the areas adjoining the two longitudinal edges overlap each other, it is ensured that thermal bridges, at which only the elastic band separates the sleeping area from the surroundings, can not arise.
- one of the two overlapping edge regions can be extended circumferentially around the sleeping area by an elastic band fastened to its longitudinal edge and finally attached again to the outside or inside of a region of the insulating layer adjoining the other longitudinal edge.
- the bag in which the heat insulating material is located does not need a single large receiving space for heat insulating Form material. Rather, it is readily conceivable that the bag is divided into a plurality of each filled with heat-insulating material chambers, which are separated from each other by appropriate seams. Also, a plurality of individual textile elements forming such chambers may be sewn together to form the pocket.
- two elastic bands are provided, each connecting one of the longitudinal edges of the insulating layer with an adjacent to the other of the longitudinal edges of the insulating region, wherein in the unstretched state of the elastic bands, the two longitudinal edges in the circumferential direction of the sleeping area have a predetermined overlap distance from each other, the overlap width Are defined.
- the complementary elastic bands one of which (namely, the longitudinal edge of the inner Isolierlagenabitess extending elastic band) on the inside of the outer Isolierlagenabitess attack and the other (namely, the longitudinal edge of the outer Isolierlagenabitess extending elastic band) on the outer side of the inner insulating layer section engages, by the tensile force generated in its expansion also for the fact that the two overlapping Isolierlagenabitese always fit tightly against each other and not stand out from each other. This is all the more true, the stronger the force exerted on insulating layer and the resulting strain of the elastic bands.
- the sleeping bag is therefore extremely robust and does not run the risk of dissolving its shape.
- the insulating layer always remains a single compact unit.
- the insulating layer is formed in the adjustment by a plurality of each filled with a heat-insulating material pockets, which are held together to form the sleeping area in the circumferential direction by a respective band, further wherein in the adjustment two layers of each held together with a band Pockets on top of each other and are offset in the circumferential direction of the sleeping area to each other and wherein in each of the layers at least one of the bands is made of an elastic material.
- the staggered arrangement of the two insulating layers inevitably formed thermal bridges are covered by the other insulating layer in the band. The two layers may slide to each other in the circumferential direction to some extent to allow locally as needed expansion of the sleeping area.
- the insulating layer in the adjustment has at least one fold in which - seen in a cross section orthogonal to the longitudinal axis of the sleeping area - the insulating layer between two fold edges bulges outwards or inwards, wherein the fold edges by the elastic band are held together.
- the fold represents an arrangement in which the insulating layer is gathered to provide material which allows some extension of the sleeping area.
- the elastic band connecting the edges of the pleat ensures that once expansion has taken place, once the pressure exerted by the body of the sleeper on the inside of the insulating layer decreases.
- the number of folds formed in the adjustment range can be chosen as desired depending on the requirements. Frequently, a single fold, which allows a relatively large maximum extension, will suffice. However, a plurality of relatively smaller folds in the circumferential direction of the sleeping area may also be arranged next to one another in order to achieve the desired maximum extent of the insulating layer.
- the fold may be formed in a cross-section orthogonal to the longitudinal axis of the sleeping area in approximately Z-shaped.
- the Z-shape of the fold leads, in addition to an inward or outward bulging, also to the formation of an overlap section formed by three sections of the insulating layer, which allows to achieve a considerable maximum expansion of the fold with only slight bulging of the fold.
- a Z-shaped fold arises, for example, when not only the two edges of a fold are held together by an elastic band, but also another elastic band is attached to a lying between the edges of the fold position and this with a side of the fold lying point of the insulating layer connects, for example, in the case of an outwardly bulging fold whose most outwardly projecting point connects to the outside of the insulating layer.
- the distance between the attachment points and the length of the other band are dimensioned so that the fold in the unstretched state of the other band does not protrude upright from the insulating layer, but is laid aside and preferably even applies to the insulating layer.
- the crease which has been put aside will, with increasing widening, ie stretching of the elastic band connecting the edges of the crease, also set against the increasing tension of the further elastic band. This provides for an increasing additional restoring force through the further band, which reliably returns the fold in the event of decreasing forces exerted on the inside of the insulating layer back into its converted and applied to the insulating original position.
- the fold is formed as a double fold with two in a cross section orthogonal to the longitudinal axis of the sleeping area in each case approximately Z-shaped folding parts, which are arranged mirror-symmetrically to each other and connected to each other.
- Each of the Z-folded portions of the insulating layer then forms an overlap portion on the outsides of the double fold and a central bulge surrounded by the Z-shaped structure therebetween.
- three elastic bands are provided in this case, which are each associated with one of the two overlapping sections and the bulge.
- the respective band connects the mutually opposite edges of the overlap section and thus ensures for a plant of the fold to the insulating layer in the folded state in which the bands are not stretched.
- the other of the bulge associated band which is arranged on the opposite side of the insulating layer, connects the mutually opposite edges of the central bulge with each other and thus ensures that the bulge after expansion is restored to its original shape.
- the central bulge cohesive band is located on the inside of the insulating layer, while the two bands at the edges of the double fold, which hold the lateral overlap sections in contact with the insulating layer, on the outside thereof are located. This arrangement ensures that the individual portions of the insulating layer, which form the double fold, compact abut each other.
- the fold may for example also be wavy. It is then advisable to attach the elastic band to the furthest to the sleeping area projecting points of the undulating fold and connect them by the elastic band.
- the insulating layer in the adjustment range then provides a relatively soft impression or "grip" through the fabric of the insulating layer, which is relatively loose in the region of the fold.
- the elastic band running essentially in the circumferential direction and always taut provides a course adapted to the body of the sleeping person. If a somewhat tighter impression of the insulating layer in the adjustment range is also desired on the outside, it is advisable to additionally or alternatively also connect the furthest outwardly projecting points of the wave-shaped fold by an elastic band.
- the elastic band is attached to the most inwardly projecting points of the outer layer and also attached to the outermost protruding points of the inner layer.
- the elastic band can be woven into the insulating layer in the adjustment. Then, due to the weave structure, each of the elastic band and the insulating layer forms a wave structure, respectively, with the bulges of the two wave structures being circumferentially offset from each other, that is, in the circumferential direction. at the point of maximum bulging outwards of the insulating layer there is a maximum bulge inward of the elastic band and vice versa.
- At least two flexible bands are provided, wherein one of the bands is arranged on the sleeping area facing side of the insulating layer and another of the flexible bands is arranged on the opposite side of the insulating layer.
- one of the bands is arranged on the sleeping area facing side of the insulating layer and another of the flexible bands is arranged on the opposite side of the insulating layer.
- two or more flexible bands may be provided to a compact and as long as possible continuous conditioning of the individual sections of the insulating layer to each other to achieve.
- the insulating layer may, for example, comprise at least one pocket formed by a substantially inelastic textile material which is filled with a heat-insulating material.
- a substantially inelastic textile material which is filled with a heat-insulating material.
- a plurality of adjoining pockets, or a divided into a plurality of pockets textile web may be provided. It does not matter here that the textile web itself is elastic. Rather, it is sufficient if sufficient through the textile web in one or more adjustment ranges Material is provided to allow expansion of the sleeping area.
- Suitable fillings of heat-insulating materials may be either natural materials, in particular down, or synthetic fibers with good bulkability.
- the elastic band in the longitudinal direction of the sleeping area is substantially continuous, so that the insulating layer can adapt to the movements of the sleeper at any height, regardless of such adjustment processes of the insulating layer in a different body height.
- the adjustment range and / or the elasticity or the length of the elastic band can be particularly large.
- the insulating layer may also have a plurality of distributed over the circumference of the sleeping area adjustment ranges in order to achieve a desired maximum possible extent.
- the elastic band allows an extension of the scope of the sleeping area by up to between 10 and 30%, preferably up to about 15%.
- a first embodiment of a sleeping bag according to the invention is generally designated 10.
- Fig. 1A shows the sleeping bag 10 in a schematic form with cut headboard, the body 12 of a lying in the sleeping area 14 of the sleeping bag 10 is schematically indicated by the shoulders and head.
- Fig. 1B shows a section around the adjustment 20 from Fig. 1A.
- Fig. 1C shows this section again in a perspective indicated representation.
- the sleeping area 14 is surrounded by an insulating layer 16, which at the in Fig. 1 embodiment shown is formed from a bag which is filled with a heat-insulating material, such as down or synthetic fibers of high bulkiness.
- a heat-insulating material such as down or synthetic fibers of high bulkiness.
- the heat-insulating material is not shown in detail.
- the in the basic form substantially trapezoidal pocket is to form the sleeping area 14 surrounding insulating layer 16 by a in Fig. 1A indicated longitudinal axis A curled into a truncated cone-like shape, so that the two longitudinal edges 18a, 18b of the pocket adjacent portions 16a, 16b of the insulating layer 16 come to lie one above the other in an overlap section.
- This arrangement provides an adjustment range 20 in Sense of the present invention, as will be explained later.
- a respective band 22a, 22b made of a resilient textile material is attached at each of the longitudinal edges 18a, 18b.
- the band 22a connects the longitudinal edge 18a of the adjustment region 20 in the outer portion 16a of the insulating layer 16 with the outside of the portion of the insulating layer 16, which continues in the adjustment 20 as an inner portion 16b of the insulating layer to the other longitudinal edge 18b.
- the band 22b connects the longitudinal edge 18b of the portion 16b of the insulating layer 16 located in the adjustment region 20 with the inner side of the portion of the insulating layer 16 which continues in the adjustment range 20 as an outer portion 16b of the insulating layer up to the other longitudinal edge 18a.
- the sleeping bag 10 thus adapts automatically to the sleeper in its respective sleeping position. This keeps the amount of air in the sleeping bag to be heated or kept warm to a minimum.
- Fig. 1B which shows the arrangement formed in the adjustment 20 in detail
- the two elastic Bands 22a, 22b generate a tensile force when stretched (in Fig. 1B indicated by dashed arrows), which drives the two superimposed sections 16a, 16b back into their starting position.
- the elastic tension of the bands 22a, 22b furthermore ensures that the two sections 16a , 16b of the insulating layer 16 always remain in abutment against each other.
- Fig. 1C It can also be seen that the bands 22a, 22b are formed continuously along the longitudinal direction A of the sleeping bag and so at any height of the body of the sleeper expansion of the sleeping area 14 as described above is possible.
- the insulating layer 16 may of course have a zipper for convenient entry and / or exit, which runs substantially along the length of the sleeping bag.
- This zipper is not shown in the figures for reasons of clarity. Since this zipper is also closed in the closed state of the sleeping bag, to which the information contained herein refers, its presence has no influence whatsoever.
- each corresponding to different embodiments of the sleeping bag according to the invention in representations Fig. 1A to 1C show the same reference numerals as in the previous figure are used for the same or equivalent components of the sleeping bag, but each increased by the number 100. To avoid repetition Reference is made to the respective preceding statements on the already explained figures.
- the insulating layer 116 in the adjustment 120 a plurality of each filled with a heat-insulating material pockets 116a - 116f, which are held together to form the sleeping area 114 in the circumferential direction by a respective band 122a - 122e.
- the pockets 116a-116g are disposed in the adjustment region 120 in two superimposed layers of respective banded pockets, the outer layer being formed by the pockets 116a, 116c, 116e and 116g respectively through the bands 122a, 122c, 122e are connected, and the inner layer is formed by the pockets 116b, 116d and 116f, which are respectively connected by the bands 122b and 122d.
- the filled with the insulating material pockets of the two layers are circumferentially offset from each other, so that the connecting the pockets bands 122a - 122e are each covered by an overlying or underlying pocket 116a - 116f the other location.
- the two layers of pockets are mutually movable in the circumferential direction, so that the pockets of the two layers can move within certain limits against each other, but not so far that two of the elastic bands come to rest on top of each other.
- the adjustment region 220 is formed by the insulating layer 216, seen in a cross-section orthogonal to the longitudinal axis A of the sleeping region 214, as in FIG Figs. 3A - 3C shown folded in approximately Z-shaped with three sections 216a, 216b and 216c, which form the legs of the fold.
- the Z-shape of the insulating layer 216 in the adjustment 220 arises in that a formed between the sections 216a, 216b of the insulating layer 216 fold 224, which bulges outward, is folded to the side and in the in Fig. 1A shown origin position in which none of the bands 222a, 222b is stretched, to a further portion 216c of the insulating layer 216 applies.
- the one band 222a is disposed on the outside of the insulating layer 216 and connects the most outwardly projecting location 218a of the fold 224 with the outside of the insulating layer 216, at a location 218b located at the edge of the adjustment area 220.
- the other band 222b is arranged on the inside of the insulating layer 216 and connects the mutually opposite edges 218c, 218d of the outwardly bulging fold 224.
- the tension exerted by the two elastic bands 222a, 222b results in a tight fit of the leg portions 216a, 216b, 216c to each other and to the outer surface of the insulating layer 216 and thus to form an overlap section. This allows the fold, with only a small bulge, nevertheless to allow a considerable maximum expansion and, after expansion, reliably moves back again into its original position, which bears compactly on the insulating layer 216.
- Fig. 4A - 4C show another one in Figs. 3A - 3C embodiment shown very similar variant.
- the insulating layer 316 in the adjustment region 320 with circumferentially contiguous sections 316a, 316b, 316c, 316d, 316e formed, which are arranged in the form of a double fold.
- the double fold has two in a cross section orthogonal to the longitudinal axis A of the sleeping area 314 each approximately Z-shaped folding parts, which are arranged mirror-symmetrically to each other.
- the rims 318a, 318b, 318c, 318d, 318e, 318f between the respective insulating layer portions 316a, 316b, 316c, 316d, 316e are interconnected by a total of three elastic bands 322a, 322b, 322c, so that each of the Z-shaped folded portions of the insulating layer 316 on the outer side of the insulating layer 316 forms an overlap portion.
- In the enclosed by the two Z-shaped folding parts space creates a central bulge 324, which bulges out to the outside of the insulating layer 316 out.
- the arrangement of the elastic bands 322a, 322b, 322c is selected such that two of these bands 322a, 322b are disposed on the outside of the insulating layer 316, with one band 322a holding together the opposed edges 318a, 318b of one lap portion and the other band 322b holds the opposed edges 318d, 318f of the other overlap portion together. Finally, another band 322c is disposed on the inner side of the insulating layer 316 facing the sleeping area 314 and connects the opposite edges 318b, 318e of the central bulge 324c.
- the elastic bands 322a, 322b, 322c provide for a close contact of the individual adjoining sections 316a-316f of the insulating layer 316.
- the insulating layer 416 has in the adjustment 420 a total of three adjoining wave-shaped folds 416a, 416b, 416c, which are held together on their inside by an elastic band 422.
- the elastic band 422 is in this case the edges 418a and 418d of the adjustment area 420 as well as at the furthest inward, ie to the sleeping area 414, projecting points 418b, 418c of the insulating layer 416, which the edges of the three circumferentially adjoining pleats 416a, 416b, 416c, attached.
- the length of the individual sections of the strip in the unstretched state between in each case two adjacent attachment points 418a, 418b, 418c, 418d is in each case shorter than the length of the corresponding section 416a, 416b, 416c of the insulating layer between the same attachment points 418a, 418b, 418c, 418d, so that form bulged outward bulging bulges.
- a sleeping bag 510 according to the invention according to FIG Figs. 6A-6C are in the adjustment 520 two layers of wave-shaped folds 516a, 516b, ... and 516'a, 516'b, ... in the circumferential direction without offset from each other over each other, wherein the elastic band 522 to the furthest inwards, ie towards the sleeping area 514, protruding points 518a, 518c, 518e of the outer layer forming wavy folds 516a, 516b, ...
- the elastic band 522 is thus disposed in a space between the two layers of undulating folds forming the insulating layer 516, and thus almost invisible.
- FIGs. 7A-7C Yet another variant of a sleeping bag 610 according to the invention, in which an elastic band 622 is woven into the insulating layer 616 in the adjustment area 620.
- the substantially undulating weave structure of the woven elastic band 622 in this embodiment is selected such that at the same time the insulating layer 616 between the puncture points of the elastic band 622 is gathered into pleats 616a-616d.
- a wave structure of the insulating layer 616 forms in the adjustment, which is opposite to the waveform of the elastic band 622, ie, the bulges of the two wave structures are circumferentially offset from each other in the circumferential direction: at the point of maximum bulging outward of the insulating layer 616 is a maximum bulge inward of the elastic band 622 and vice versa.
