Description

Sleeping bag adapted to join a mattress.

Technical field

[0001] The present invention is in the technical field of sleeping bags.

[0002] The camper's equipment in general, and in particular a sleeping bag, must fulfill three main functions: to be light and compressible since the camper may have to carry his material, particularly during the march, he needs to therefore being able to place your material in a small space, such as a backpack; and be insulating since the camper may have to sleep outside and / or at low temperatures.

[0003] A sleeping bag generally has as many insulating materials in its upper part as in its lower part. It is understood by insulating materials, the amount and density of wadding and / or down and / or waterproof layers; and in general all the materials that contribute to improve the insulation of the sleeping bag. Down means any material comprising feathers and waterproof layer, any layer coated with a water repellent finish. Obviously, the insulating layers that have a low density contribute insignificantly to the thermal insulation of the sleeping one.

[0004] In a desire to optimize weight and compressibility, some sleeping bags that are sold have fewer insulating materials in their lower part than in their upper part.

[0005] Indeed, when a camper sleeps on his back, the lower part of the sleeping bag is then compressed against a foam or inflatable mattress, thereby evacuating any air capable of forming an insulating envelope. Moreover, since the mattresses often have a waterproof and insulating face on the floor, the lower part of the sleeping bag comprising insulating materials represents a dead weight for the camper. As these materials are expensive, particularly when it comes to down, the optimization of the thermality of the bottom of a sleeping bag also presents an economic interest.

[0006] However, this arrangement of the sleeping bag is not satisfactory. Indeed, while the camper is sleeping, he must remain theoretically lying on his back to take advantage of the thermal protection of the upper part, which in practice is difficult for the camper. In order to prevent the camper from turning around and force him to remain in the same position lying on his back, the mummy-type sleeping bags have a hood arranged at the bottom. This provision is not comfortable for the camper as he is forced to sleep on his back and has no freedom of movement.

[0007] Another proposed solution is to provide at the bottom of a sleeping bag a pocket that serves as a bed for a mattress in order to prevent the sleeping bag from sliding down the mattress.

[0008] This arrangement is not optimal since the face of the sleeping bag in contact with the ground must meet some characteristics of mechanical and punching resistance, usually typical of the face of the mattresses in contact with the ground, which involves the use of heavier and less compressible materials than the bottom of a classic sleeping bag. Said pocket represents a dead weight for the camper and an extra cost in the production of the sleeping bag in question. On the other hand, said pocket has a predetermined shape according to the shape of the lower part of the sleeping bag; It is not, therefore, universal, and is limited to some forms of mattress usually produced by the same manufacturers as the sleeping bags in question.

[0009] Thus, document US 4,757,832 is intended for a sleeping system comprising a mattress 26, a floor protection panel 12 disposed between the mattress 26 and the floor (see Figures 4 and 5), a lower part 16 arranged directly on the upper face of the mattress 26 and comprising pockets with their two ends suitable for receiving the upper and lower ends of the mattress 26, and an upper part 112 superimposed when used on said lower part 16. The panel of floor protection 12, which serves as the basis for the assembly of a store, also includes lateral projections 52, 54 provided with fixing elements 55, 56 at their ends as well as fixing belts 70 that allow the user to collect and keep the sleeping system in its folded state (see figure 8). This sleeping system reproduces the aforementioned inconveniences, particularly those related to the mattress pockets. In addition, it is bulky and complicated to assemble.

[0010] Another solution that is commercialized consists in proposing some covers that must be fixed directly on the upper face of the mattress by any of the usual means of the state of the art, such as self-adhesive bands of the velcro® type or a zipper closure. This solution is not hygienic for the camper since during sleep he breathes a lot and it is more difficult to wash a mattress than just a sleeping bag. Instead of a cover, some sleeping bags are proposed to fix them directly on the top face of a mattress. This last solution has the disadvantages of being uncomfortable for the person sleeping because it has little freedom of movement. In addition, the camper is not protected while lying down from the direct passage of outside air at the level of the junction between said sleeping bag and the mattress, it is what is designated by the term thermal bridges.

[0011] When the camper sleeps at low temperatures, particularly in the mountains, he needs a very insulating sleeping bag, in particular with a small volume of air to heat with body heat, and compressible for transport. On the contrary, in conditions of moderate temperatures, particularly in a coat, or inside a tent, the sleeping bag does not need to be so insulating and should provide greater freedom of movement. Currently to meet these two conditions, the camper must be equipped with two different sleeping bags.

[0012] In order, in particular, to alleviate the aforementioned drawbacks, the present invention has as its object a sleeping bag adapted to be attached to a mattress, said sleeping bag comprising an overlapping upper part and a lower part, said part lower being intended to be in contact with the upper face of said mattress, which is characterized in that it comprises:

a) a first flap that extends over the entire contour of said lower part and suitable for covering the lower face of said mattress along all its edges in an enveloping position in which the lower part of the sleeping bag is placed against the upper face of said mattress;

b) a second flap that partially borders said upper part, said second flap being able to cover the lower face of said mattress along at least its rear edge and its two longitudinal and opposite edges, and possibly said first flap, in an enveloping position in which the lower part of the sleeping bag is placed against the upper face of said mattress;

c) first removable fixing means suitable for gluing said first flap against the lower face of said mattress in said wrapping position and second removable fixing means suitable for gluing said second flap, and possibly said first flap, against the lower face of said mattress in said enveloping position.

[0013] A flap is understood as part of a textile article or an object, such as the upper or lower part of the sleeping bag according to the present invention, or an element added by any of the usual means of the prior art. to said article or said object; of a flexible material, which folds over another textile object or article, such as an inflatable mattress or a foam mattress.

[0014] Preferably, its longitudinal edges are designated by at least two opposite edges of the mattress.

[0015] By detachable fixing means, it is understood that the fixing is removable. Indeed, the sleeping bag can be used without being attached by said means to the mattress, in the unbuttoned position. This arrangement allows the sleeping bag to be versatile. In fact, this can be used in mild outdoor conditions such as in a coat where the unbuttoned position of the bag offers great freedom to the sleeping person. On the contrary, in cold outdoor conditions, since the sleeping bag is attached to the mattress in said enveloping position, the sleeping space is reduced which improves the thermal comfort of the sleeping person since the volume of air that has to be heated The body is smaller.

[0016] Being the sleeping bag that carries the fixing means, these are independent of the mattress and allow the sleeping bag to be attached to mattresses of different shape and size.

[0017] Advantageously, by wrapping the first flap only the periphery of the upper face of said mattress at least along two of its opposite edges, the lower face of said mattress, generally designed in a material resistant to punching and abrasion is directly in contact with the ground. It is not necessary that said flap is made of a puncture resistant material, which improves its compressibility and its lightness.

[0018] On the other hand, said removable fixing means allow the sleeping bag to be fixed to the mattress along at least two of its opposite edges without sliding on the mattress. In this way, the camper can sleep on sloping floors.

[0019] There are no thermal bridges in the mattress area or zones that the flap wraps around, which contributes to improving the camper's thermal comfort.

[0020] While sleeping, the camper is not forced to sleep lying on his back since, whatever his position, he moves into his sleeping bag attached to the mattress. In addition, the camper has a larger sleeping space than a mummy-type sleeping bag, since the upper part of the sleeping bag covers the upper face of the mattress.

[0021] Preferably, the upper part has dimensions larger than those of the lower part so that a sleeping space is obtained, delimited between said parts, in which the user can move and turn around easily.

[0022] The upper and lower parts may be made of a single textile layer, possibly waterproofed, or in several classic layers as found in sleeping bags comprising several layers of wadding or down.

[0023] Finally, the thermal insulation function is guaranteed by the upper part of the sleeping bag, on the one hand, and the lower side of the mattress, on the other hand, is not useful for the camper's thermal comfort than the lower part from said sleeping bag, include insulating materials. Preferably, the inner face of this lower part in direct contact with the camper can be made of a material that is pleasant to the touch to improve its comfort.

[0024] This arrangement allows to save on expensive insulating materials, and considerably improve the lightness and compressibility of the sleeping bag.

[0025] On the other hand, the sleeping bag can be used without a mattress that has an insulating underside, such as a simple mattress, when the camper sleeps in a covered place, such as inside a tent or in a shelter.

[0026] In a variant, said first flap is continuous, in one piece, along the entire perimeter of the lower part.

[0027] In a variant embodiment, access means, such as a zipper closure, to the sleeping space delimited between the upper part and the lower part are arranged in an area of the second flap intended to cover the said enveloping position lower face of the mattress along at least one of its longitudinal and opposite edges.

[0028] The thermal insulation of the space between the upper face of the mattress and the upper part of the sleeping bag is improved since the means of access to the sleeping space are located on the lower face of the mattress when used.

[0029] In a variant embodiment, the second flap extends over the entire contour of the upper part, with the exception of the area of said contour corresponding to the head of the sleeping person.

[0030] This arrangement is preferred and optimal for the thermal insulation of the user since thermal bridges are minimized.

[0031] In a variant, the area of the contour of the upper part corresponding to the head of the sleeping person lacks the first or second flap, and in said area the upper part comprises two lateral wings provided with fasteners. apt to cooperate in its closure and form a circular space destined to receive the head of the sleeping person.

[0032] Preferably, the lateral wings are of a material pleasant to the touch and thermally insulating. The side wings improve the thermal insulation and comfort of the user's head by acting as a pillow.

[0033] In a variant embodiment, the side wings have a "U" shaped configuration open towards the front of said bag.

[0034] This configuration is optimal to form a comfortable circular space to receive the head.

[0035] In a variant embodiment, said second flap is continuous, in one piece, along all or part of the contour of said upper part.

[0036] In a variant embodiment, said first flap is formed on the same panel as the bottom.

[0037] This provision has the advantage of making at the same time one of the parts of the sleeping bag and said first flap, and therefore suppresses additional and expensive operations that consist of adding said first flap throughout the entire contour of the bottom.

[0038] Preferably, said first flap and the bottom are continuous and in one piece, which improves the camper's insulation at the level of the mattress area that envelops said first flap by suppressing the thermal bridges.

[0039] In a variant embodiment, said second flap is formed on the same panel as the upper part. Preferably, the first flap is then formed on the same panel as the bottom. The first flap and the second flap then cover the same edges of the lower face of the mattress together in said enveloping position.

[0040] In a variant embodiment, said first flap is provided with all or part of its periphery of a sheath and said first fixing means comprise an adjustment cord, in particular elastic, that slides through said sheath and possibly an element cord lock in the adjusted position.

[0041] Advantageously, the sleeping bag has an adjustable amplitude, since when the first flap is attached to the lower part and indirectly to the upper part, it is deformable along all or part of its periphery, of This way the camper has total freedom of movement.

[0042] By means of the adjustment cord, the camper easily adjusts the placement of the flap on the mattress and locks it in this position either by knotting said cord or with a locking element, for example a tonka ®.

[0043] In a variant embodiment, said first flap and said second flap are provided with all or part of their periphery of a common sheath, and said first and second fixing means comprise an adjustment cord, in particular elastic, which is slides through said sheath and possibly a cord locking element in the adjusted position.

[0044] In a variant embodiment, said first flap comprises on all or part of its periphery an elastic edge that functions as first fixing means.

[0045] Said edge may be a tape added by sewing.

[0046] In a variant embodiment, said first flap and said second flap comprise all or part of its periphery a common elastic edge that functions as said first and second fixing means.

[0047] In a variant embodiment, said first fixing means comprise at least one fastening means, in particular equipped with hooks, which makes it possible to hold two opposite edges of said first flap or of said first and second flaps.

[0048] Preferably, said fixing means consist of an elastic adjustment cord. The camper's freedom of movement inside the sleeping bag and his attachment to the mattress are enhanced.

[0049] In a variant embodiment, the lower part and / or the first flap surrounding said lower part comprises an opening for the passage of inflation and / or deflation means of the mattress, such as the valve of a self-inflating mattress .

[0050] In this way the sleeping bag can be stored attached to the mattress since during the compressive folding of the assembly on itself, for example by winding, the air ejection hole of the mattress is not obstructed. Similarly, when preparing to sleep, once the sleeping bag attached to the mattress is deployed, the inflation means are accessible.

[0051] When the sleeping bag comprises a second flap that extends over all or part of the contour of the upper part, with the exception of an area d corresponding to the head of the sleeping person, the opening is preferably made in front of said zone d.

[0052] The subject of the present invention is also a sleeping set, comprising a sleeping bag according to any one of the embodiments described above and a mattress, with a determined thickness, characterized in that it comprises a joining means that allows said sleeping bag and said mattress to be held together in a rolled position, said mattress being attached to the sleeping bag by means of said first flap or possibly of said first and second flaps.

[0053] Advantageously, the camper collects the sleeping bag and the mattress together by winding together which eliminates the cumbersome folding stages. When the mattress is inflatable, it is deflated during this winding stage.

[0054] When the camper prepares to sleep, it is enough to unwind the assembly comprising the sleeping bag attached by means of the flap and said fixing means. In this way, you only have to place the sleeping bag flap only once on the mattress during an excursion or crossing. Preferably, the mattress is self-inflating, thus when said joining means is unbuttoned, the assembly described above is unwound without help.

[0055] The joining means may be, for example, a tie provided on the sleeping bag.

[0056] The present invention will be better understood by reading the description of the embodiments, which are cited by way of non-exclusive, and which are illustrated in the following attached figures:

[0057] The present invention aims to propose a lightweight, compressible, comfortable sleeping bag that offers good thermal comfort to its user, and that can be used both outdoors in low temperature conditions and in a sheltered environment Like a shelter or a shop.

[0058] The sleeping bag 12 shown in Figure 1 comprises a first flap 52 and a second flap 53. The first flap 52 is continuous and in one piece along the entire contour of the periphery of the bottom 42. The second flap 53 is continuous and in one piece along the entire contour of the periphery of the upper part 32, except along the edge 62d which corresponds to the passage made in the sleeping bag 12 in order for the user to I can slide inside. The first flap 52 is made in the same panel as the lower part 42 and the second flap 53 is made in the same panel as the upper part 32. The first flap 52 and the second flap 53 border the lower face 62 together and wrap the edges 62a, 62b, 62c of the mattress 22 overlapping. The first flap 52 envelops all the edges of the mattress 22 including the edge 62d. This arrangement is especially advantageous since it suppresses all thermal bridges and improves the thermal comfort of the user.

[0059] The first flap 52 and the second flap 53 are provided on their entire periphery with a common sheath f1, through which an elastic adjustment cord 82 slides. The cord 82 is provided with a locking element 82a, for example TONKA® type. The cord 82 leaves the sheath f1 in particular by four zones provided therein in such a way that two fixing means 92 and 93, for example hooks, hold the two opposite edges of the first and second flaps 52 and 53. The bag sleeping 12 is thus perfectly attached to mattress 22 and cannot slide on it. Through the elastic means provided by the cord 82, the sleeping bag allows the user freedom of movement while he sleeps.

[0060] Once the sleeping bag 12 is attached to the mattress 22, they can be kept rolled together by means of a joint, such as a storage bag or a tie arranged on the sleeping bag

12. In Figure 6, the sleeping bag 12 and the mattress 22 are shown as they unfold. Preferably, the mattress 22 is self-inflating so that the bag 12 and the mattress 22 are deployed without help. In this way the user has a sleeping set that is easy to transport and install.

[0061] In Figure 2, the sleeping bag 12 is shown without the mattress 22 in the unzipped position, the first fixing means 82, 82a and 92, 93 being removable. It is then observed that the sleeping space is larger since the first and second flaps 52 and 53 are made in the same panel as the parts that are bordered and are only joined along the common f1 sheath. Preferably, said panels are a simple textile layer. The upper part 32 has the same thermal insulation capacity as the lower part

42. In this way the sleeping space is no longer limited only along the upper face of the mattress 22, but also includes the space formed by the two flaps 52 and 53. In this way the camper has a sack of multi-purpose sleep that can be used in cold conditions in the adjusted position when the fixing means 82, 82a and 92, 93 are closed, the volume of air that has to heat the body heat being smaller; and that it can be used inside a coat, a shop or in a house, since said fixing means are open, the camper has a sleeping bag 12 with greater freedom of movement, thermal insulation being a less important factor.

[0062] On the other hand, mattresses that are marketed generally having a lower face, in contact with the ground, made of a material resistant to punching and abrasion; and the lower face 62 of the mattress 22 being poorly covered by the flaps 52 and 53, it is therefore not necessary to make said flaps in a material especially resistant to punching.

[0063] In the example described above, the flap 52 is preferably made of the same panel as the bottom 42. Said panel is preferably a simple textile layer, for example a polyester fabric. This arrangement suppresses the operations that consist of adding and fixing a flap on all or part of the contour of the periphery of one or the other of said lower and upper part by any of the usual means of the prior art, for example by sewing.

[0064] The flaps can also be detachably fixed at the bottom, for example by means of self-adhesive Velcro® bands.

[0065] Figures 3 to 6 represent a second preferred example of a sleeping bag according to the present invention in said enveloping position.

[0066] The sleeping bag 13 is very similar to the sleeping bag 12 because it comprises a first flap 54, continuous and in one piece, which extends throughout the contour of the lower part 43 so that it covers in said position enveloping the mattress 23 along all its edges; and a second flap 55, continuous and in one piece, which extends throughout the contour of the upper part 33, with the exception of the area d of said contour corresponding to the head of the sleeping person. The first 54 and the second 55 flaps are added, preferably, by sewing them on the lower parts 43 and upper 33. The upper part 33 has dimensions larger than those of the lower part 44 such that a space is obtained for Comfortable sleep in which the user can move freely.

[0067] Unlike the sleeping bag example 12 shown in Figures 1 and 2, the upper part 33 and the second flap 55 are sized such that they cover the upper edge 63d of the mattress 23 to the maximum and prepare a Wide enough and comfortable head area to improve thermal insulation.

[0068] In addition, the area d for the passage of the head comprises two lateral wings l1 and l2 provided with fasteners 14 and 15 at their ends suitable for cooperating in its closure and forming a circular space intended to receive the head of the He sleeps In this specific example, the fasteners 14 and 15 are self-adhesive bands of the Velcro® type. The lateral wings l1 and l2 have a U-shaped configuration open towards the front of the sleeping bag 13. The lateral wings l1 and l2 are preferably added by sewing on the upper part 33, but can be added by means of detachable fastening means carrying said wings and the upper part so that the user can remove the lateral wings l1 and l2. The lateral wings l1 and l2 are preferably made of a soft-touch and thermally insulating material, at least more than the material that forms the lower part 43. The lateral wings l1 and l2 support the head and insulate it from the cold.

[0069] On the other hand, access means, here a zipper closure z, to the sleeping space delimited between the upper parts 33 and lower 43 are provided in the second flap 55 in such a way that they cover the lower face of the mattress a along the longitudinal edge 63b in said enveloping position and reducing the thermal bridges between the upper part 33 and the mattress 23.

[0070] Finally, an opening 16 is provided between the lower part 43 and the first flap 54, facing the area d for the passage of inflation and / or deflation means of the mattress 23, in this particular example the valve of a self-inflating mattress 17. The opening 16 allows the bag 13 to be collected together with the mattress 23 since it is not necessary to separate them to inflate or deflate the mattress 23.

[0071] The sheath f2 through which the elastic adjustment cord 83 slides comprises an additional opening 18 with respect to the sleeping bag 12 and located towards the rear edge 63d of the mattress 23 which allows the user to more easily adjust the support from bag 13 on mattress 23.
