Description

SLEEPING ASSEMBLY

The present invention relates to a sleeping set consisting of a sleeping bag and a cover for storing said bag. It is essential for a camper or a hiker, and generally for any person practicing an outdoor activity over an extended period, optimize the volume and weight of the material it carries so that it is not embarrassed by bulky objects when he moves and can dispose at will, once the largest objects placed in his backpack, enough space to easily accommodate other objects or vice versa.

For this purpose it is known to place the sleeping bag, essential in particular in the equipment of a hiker but bulky, folded into a second bag or cover that is specifically intended to reduce its size by evacuating the air contained in the cover and the sleeping bag so that the cover conforms to the shape of it.

In US 6,089,752, the sleeping bag is stored in a cover whose main body has a cylindrical configuration and has at its two ends, compression covers connected by straps. The main body is made of a flexible material; it comprises a main opening for introducing and extracting its contents and an anti-return valve. The bringing together of the two hoods thanks to the traction exerted on the straps makes it possible to compress the sleeping bag and the main body of the cover. The non-return valve allows excess air to escape from the cover when it is squeezed.

The assembly thus compressed, with externally the presence of two compression caps and straps which is particularly troublesome, has a shape that necessarily remains cylindrical and not adapted to the configuration of the space available inside the backpack. Generally the sleeping bag in its cover is placed rolled on itself on the upper part of the backpack and held there by a flap with a fastener. In this arrangement, the entire sleeping bag and cover extends transversely of the shoulders of the hiker and is more likely to clutter and be damaged than if it were placed directly in the backpack. The airtight closures of the introduction opening, by which the sleeping bag is arranged in the cover, generally employed are of the zipper type, for example those commonly known as plastic zip® for the packaging bags. . The slide fasteners generally comprise a male element in the form of a rib capable of cooperating for its closure with a female element in the form of a slide. The Applicant has found that this type of closure of the introduction opening is not impermeable to air in a sustainable manner since generally about two hours after compressing the assembly for sleeping the one resumes its initial volume corresponding to its state uncompressed. The present invention presents an alternative of a coating assembly which makes it possible in particular to overcome the aforementioned drawbacks.

The coating assembly according to the present invention is composed of a sleeping bag and a cover for the storage of said bag, free of compression means. Said cover comprises an air exhaust element provided with closure means and a first portion and a second portion delimiting an introduction opening adapted to allow the placement of the bag inside the cover in a predetermined configuration. Typically said first and second parts are equipped with fastening members in a cohesive material able to cooperate for their airtight closure by pressing them against each other, so that:

after placing the bag in the cover, the assembly having a given average thickness E ₀ , then after a simple compression by the user of the assembly to expel the air that it contains through the exhaust element and to make the fasteners cooperate, and finally after actuation of the closing means of the air exhaust element, the assembly is presented under said determined configuration and has a mean thickness El stable in time and less than the thickness Eo.

Average thickness EO of the assembly means the average thickness occupied by the cover after introduction of the sleeping bag. Depending on the size and initial configuration of the storage bag, the hiker or camper adapts the configuration of the sleeping bag to be placed in the said cover to obtain a set of determined configuration: the sleeping bag can be introduced into the cover to the unfolded state or in the folded state, for example in two or three, or in the wound state, or even balled.

By determined configuration, we mean the general shape given to the cover / sleeping bag; it may for example be substantially flat, of rectangular or oval shape; it can be three-dimensional, cylindrical. Said fastening members are preferably arranged transversely inside the cover near the insertion opening or so as to delimit the periphery of said opening.

The closing means of the air exhaust element, and possibly the closing means of the introduction opening, allow the air trapped in the assembly and evacuated by compression, can not reintegrate the together in time.

Cohesive material is understood to mean any self-adhering material and / or capable of adhering to a material of a different nature but also cohesive by simple contacting and pressing of said materials together in a repositionable manner as many times as desired, without slipping or adhering to dust or particles. Said fastening members are detached for the opening of the cover when the user exerts opposing traction on both sides of said first and second parts.

One of the aims of the present invention is to obtain a compressed assembly formed of the sleeping bag and the cover, of average thickness E1, which can be placed easily and rapidly in the determined configuration, depending on the location available in the backpack. Due to its reduced volume once the set disposed in the backpack, it is possible to place other objects, which maintain the compressed assembly, and the hiker is not embarrassed in his movements because the together do not protrude outside of it. In addition, the set is protected by the backpack degradations and bad weather in addition to its storage cover.

When the assembly has a substantially flat configuration and it is placed in the backpack directly on the face covering the back of the hiker, it covers perfectly the back of it and does not create a feeling of discomfort on the contrary it eventually dampens other objects, sometimes metallic, placed in the same bag. Also, the form of said compressed assembly adapting to the shape of the housing in which it must be stored, once all the objects arranged in a backpack, it adapts to the remaining place. The simple compression that allows the expulsion of the air contained in the sleeping bag and the cover by the exhaust element, is obtained by compressive winding of the assembly on itself or possibly by exerting the weight of the hiker's body on said set or the combination of both. During this same step of compressing the assembly for coating, the user by winding the assembly on itself also exerts pressure on said fastening members and makes them adhere against each other so to obtain the airtight closure of the introduction opening. The applicant realized that this type of closure implementing a cohesive material allowed the assembly to maintain a thickness E1 in a permanently compressed state. It is not necessary to actuate once the compression step is complete of the airtight closing members of the introduction opening such as on the covers of the state of the art generally causing the re-opening. introducing air through said opening. In an alternative embodiment, the assembly has a determined substantially flat configuration, in particular rectangular, and compression of the assembly is by compressive winding of said assembly on itself.

This determined configuration offers more opportunities for the hiker to store the compressed set at will; the shape of a backpack and a sleeping bag being substantially rectangular, the assembly can be folded or not at the bottom of said bag, wrap and / or cover objects placed in the backpack or rolled on him -even.

In an alternative embodiment, the air exhaust element is the introduction opening.

In this variant, the closing means of the air exhaust element are the fasteners in a cohesive material.

The step of compressing the assembly by winding on itself is in this case preferably from the area of the cover opposite to said opening towards said opening.

Preferably, a complementary closure system for example self-gripping loops and hooks in the form of two complementary tapes is disposed transversely inside the cover near the insertion opening. This complementary closure system is not closed when it is airtight, but it prevents the sleeping bag from coming out of the cover during the compression of the assembly, which in this case progressively proceeds from from the opposite of the introduction opening to it.

In an alternative embodiment, the airtight closure of the insertion opening comprises a portion of the cover adjacent to said opening rollable on itself and associated with a transverse fastening strap acting as a handle.

This type of closure will be designated in the following description

"Canyon type closure". Said transverse strap is fixed on a portion of the outer periphery of said opening and has at both ends of the closure elements. The said portion of the cover is blocked in its wound position by the actuation of the closure elements of the transverse strap, which thus forms a carrying handle of the coating assembly.

In another embodiment, the portion of the cover adjacent to said opening comprises a flap and, attached to said flap, a transverse strap whose ends are provided with closure elements. The introduction opening is closed by folding the flap to said opening, by winding the flap and the portion of the cover bordering the introduction opening around the transverse strap and then actuating the closing elements of the strap. During this step of winding the flap, the fastening members of the introduction opening are pressed against each other and sealingly close said opening.

When the air exhaust element is the introduction opening, the operation of the canyon type closure is performed once the compression of the assembly and the evacuation of air in the sleeping bag and the cover made.

In an alternative embodiment, the exhaust element of the air is independent of the introduction opening, and is mounted on the cover opposite said opening. In this case, the compression step of the assembly is progressively from the area of the closed introduction opening to said open exhaust element.

In an alternative embodiment, the air exhaust element is a valve and the closing means of the valve consist of a check valve whose actuation is automatic, or consist of a plug. In a sub-variant embodiment, a sprocket is placed inside the cover on either side of the valve so that the latter is not obstructed during compression of the assembly by the user. . Indeed, during compression it is possible that the sleeping bag comes to be placed on the valve and slow down, see completely blocks, the expulsion of air from the set. The sieper covers part or even the entire portion of the valve located inside the cover. In the latter case, it presents fillings to allow air to flow from the inside of the cover outwardly through the valve orifice. It is for example in the form of a bow placed on either side of said portion of the valve forming a bridge above it. In an alternative embodiment, the fasteners are in the form of a first band and a second band having a width at least of the order of 1 cm, preferably at least of the order of 5 cm. and said first and second strips are disposed substantially opposite one another transversely to the insertion opening. Preferably, the first and second strips have a width greater than or equal to 5 cm, and more particularly a width equal to 15 cm.

In an alternative embodiment, the cohesive material is a thermoplastic polyurethane (TPU) having a Shore A hardness of the order of 95, a tensile strength greater than 650 kg / cm ² , an elongation at break greater than 500% and an elastic modulus at 300% elongation greater than 150 kg / cm (ASTM D412).

The applicant has selected this thermoplastic polyurethane because it has been found that it provides a better lasting seal of the introduction opening compared to that obtained with other cohesive materials. In an alternative embodiment, the cover is formed of a first panel and a second panel coated on their respective faces respectively with a first film and a second film, both in a polymer material giving them a function of impermeability to air. The term "faces" refers to the faces facing towards the inside of the cover, opposite faces facing towards the outside of the cover. The first and second panels are preferably textile panels, the face faces preferably have a pleasant touch.

In a variant, the first and second panels are assembled, according to their peripheral edges, with the exception of the area of the insertion opening, and the first and second strips are respectively assembled to the reverse faces of said first and second panels in said zone, in particular by thermo-welding, ultrasonic welding or high-frequency welding.

As said panels are preferably coated on their faces towards airtight films, the weld types provided above make it possible to obtain welded peripheral edges that are perfectly airtight.

In an alternative embodiment, the average thickness E1 of the compressed assembly is of the order of 0.3 to 0.8 times the average thickness EO of the uncompressed assembly.

The compression ratio varies from 20 to 70% depending on the composition of the sleeping bag.

In an alternative embodiment, at least one attachment system of the sleeping bag is fixed inside the cover.

This fastening system facilitates the compression operation and the storage of the assembly once compressed, since the sleeping bag is no longer freely disposed within the cover but is held therein possibly folded.

The fastening system may be in the form of flat straps provided at their ends with hook-and-loop self-gripping fastening system or for example one or more perforated flaps to facilitate the passage of the fastener. air during compression, arranged near the area of the introduction opening.

In an alternative embodiment, said fastening system comprises closure means of the hook and loop type in the form of two ribbons attached transversely to the inside of the cover, facing each other. at a determined distance from the introduction opening.

In a variant, the sleeping bag storage bag acts as a pillow and the air exhaust element is a simple valve provided with closure means. The user can inflate the cover by blowing air through the valve, after closing the introduction opening by actuating said complementary fastening members. The single valve can be closed with a suitable cap. Preferably, the assembly comprises a mattress, in particular pneumatic, and fastening means are provided on the cover and on the mattress so as to secure the cover, for example as a pillow, said mattress. These fixing means are for example two complementary ribbons type self-gripping loops and hooks or include snaps. Said fixing means may be arranged on the reverse side of said cover and on the upper face of said mattress so that the pillow is secured to the upper face of said mattress. They can also be arranged along their edges so that the pillow is in line with said mattress. In the latter case, said mattress is lighter and less bulky than a conventional mattress since its size is reduced and does not take into account a location to wedge the head of the hiker, this function being performed by said cover once inflated.

The present invention will be better understood on reading the description of two examples of coating assemblies, cited by way of non-limiting example and for which only the first example is illustrated by the appended figures below:

- Figure 1 is a schematic perspective representation of a first example of a set for sleeping, rectangular and substantially flat, before the introduction of the sleeping bag in the cover;

FIG. 2A is a diagrammatic representation in perspective of the winding step on itself of the flap of the cover;

- Figure 2B is a schematic representation in perspective of the closure of the closure elements of the ends of the transverse strap;

FIG. 3 is a diagrammatic representation in perspective of the compression step of the assembly;

- Figure 4 is a schematic representation in perspective of the set once compressed. - Figure 5 is a schematic side view of a sleeping set with a mattress and wherein the cover serves as a pillow.

The set for sleeping 1 represented in FIG. 1 is composed of a sleeping bag 3 and a cover 2 for storing the bag 3. The cover 2 is equipped with a single valve 4 which acts as an element exhaust air and which is provided with a cap 5 as closure element. The valve 4 is mounted opposite the opening 6 allowing the introduction of the sleeping bag 3 according to the FO arrow inside the cover 2. The first part 2a and the second part 2b of the cover 2 define the introduction opening 6 and are equipped with complementary fastening members 13a and 13b in a cohesive material capable of cooperating for their airtight closure by pressing them against each other. Said fastening members 13a and 13b are in the form of a first strip 14a and a second strip 14b having a width I of the order of 5 cm. Said strips 14a and 14b are arranged facing each other transversely to the insertion opening 6 and inside the cover 2. The sleeping bag 3 is here folded in three to fit to the dimensions of the cover 2. The airtight closure of the insertion opening 6 comprises a portion 6a of the cover 2 adjacent to said opening 6 and on which is fixed a transverse strap 8 whose ends are provided with a closure element of the loop type, with a male part 9 and a female part 10.

The cover 2 has a substantially flat and rectangular configuration. When the sleeping bag 3 is placed inside the cover 2 preferably folded, the introduction opening 6 is closed by winding the strips 14a and 14b against each other (Figure 2A) according to the arrow F1 so as to obtain, on the one hand, the tight closure of the insertion opening 6 since the strips 14a and 14b are pressed against one another during the compressive winding adhering to each other, and on the other hand the partial expulsion of the air contained in the assembly since the plug 5 of the valve 4 is removed. In FIG. 2B, the male part 9 of the closing element of the ends of the strap 8 is engaged with its complementary female part 10 which makes it possible to block the closure of the introduction opening 6 and more particularly the strips 14a and 14b in a wound position on themselves, and to form a carrying handle of the assembly 1. At rest, the assembly 1 occupies a substantially rectangular configuration very bulky, of average thickness EO. In FIG. 3, in order to reduce the volume occupied by the assembly 1 and thus to reduce the average thickness Eo and to obtain a substantially flat configuration, the assembly 1 is compressed by a simple compressive winding on itself progressively along the arrow F2 from the introduction opening 6 to the valve 5 open to allow the evacuation of air. It is also possible to compress the assembly 1 by applying on it the flat weight of the user. When the air trapped in the cover 2 and the sleeping bag 3 has been expelled, the valve 5 is closed by means of the stopper 5, thereby preventing the air from entering the said set 1 again via the valve 5.

It is possible to perform the compressive winding in a single operation and to block the closing of the insertion opening 6 by means of the male 9 and female 10 parts only after said compressive winding and closing of the valve 5 This procedure may be preferable to obtain a uniform compression of the assembly over its entire width, without the extra thicknesses due in particular to the presence of the male and female parts 9.

It is possible to replace the single valve 5 by a valve with non-return valve, which facilitates the closure of the valve since it is automatic. The air exhaust element is preferably completed by a sieving device, not shown, preventing the valve 4 from being obstructed inside the cover 2 by the sleeping bag 3 during the compression of the airbag. assembly 1. The sprocket is for example in the form of a hoop placed on either side of the valve 4 inside the cover 2, the top of the hoop being arranged with regard to the exhaust port of the valve 4. The sprocket is assembled to the cover by gluing. If it is plastic, it can be assembled by thermo welding or dielectric welding according to the compatibility of the materials to be welded together.

It is possible to provide a fastener, not shown in this example, fixed inside the cover, to hold the sleeping bag 3 in its folded position during compression and once the set 1 stored for example in a bag backpack. Said fastener may be for example a transverse strap provided at both ends with hook-and-loop self-gripping type fastening means.

In FIG. 4, the assembly 1, represented once the compression step is complete, has the same substantially rectangular configuration as the uncompressed assembly but a thickness E1 reduced relative to Eo. Depending on the type of coating to be compressed, the average thickness E1 is of the order of 0.3 to 0.8 times the average thickness EO of the assembly at rest. Applicant has found that the airtight closure of the introduction opening implementing complementary fastening members 13a and 13b in a cohesive material allowed to maintain the set in a compressed state El stable in time unlike zip® plastic type closure systems used in the state of the art.

The assembly 1 and compressed rectangular configuration has a configuration and a size easier and faster to store in a backpack, for example for a hiker or a camper, a set that would have a cylindrical configuration, although a such configuration is not excluded.

The sleeping bag 3 is protected from the weather and the risk of tearing, in addition to its storage bag 2, by the backpack containing it.

The cover 2 is formed of a first panel 11 and a second panel 12 (FIG. 1), preferably of polyamide and coated on their faces with respect to 11b and 12b respectively of a first film 11 'and a second film 12 'in a polymer material conferring said panels 11 and 12 impervious to air and liquids. The faces facing 11b and 12b form the inside of the cover 2 in contrast to the faces places 11a and 12a forming outside. The panels 11 and 12 are assembled by thermo welding according to their peripheral edges, with the exception of the zone of the insertion opening 6. The first and second strips 14a and 14b are also assembled, in particular by heat-sealing transversely to the introduction opening 6 and inside the cover in order to delimit it. By way of example, the strips 14a and 14b are in a cohesive material such as a thermoplastic polyurethane (TPU), more particularly having a Shore A hardness (according to the ASTM D2240 method) of the order of 95; a tensile strength greater than 650 Kg / cm ² , an elongation at break greater than 500% and an elastic modulus at 300% greater than 150 Kg / cm (in the warp and weft directions according to ASTM D412 ). The applicant has selected this TPU among many other cohesive materials because it is the one that gives the best results to achieve a tight and durable closure of the introduction opening. This type of welding allows a tight assembly to air and water since there are no perforations due to the seam. Nevertheless, it is possible to assemble the first and second panels 11 and 12 by stitching. In this case, in order to ensure good airtightness, a band to be sealed is arranged to cover the sewn edges including said seam, and is assembled by thermo welding or ultrasonic welding or high frequency welding. Preferably, the faces places 11a and 12a of the first and second panels 11 and 12 are coated with a primer giving them a liquid impermeability and a good water repellency, for example based on fluorine, in order to improve the protection of the bag of sleeping 3. The hiker can improve his sleeping, by inflating the cover 2 by the mouth in the single valve 5 so as to form a pillow. The insertion opening is then closed in a sealed manner by the complementary fastening members 13a and 13b, not shown in FIG. 5, and reinforced with a so-called canyon closure implementing the transverse strap 8 and the fastening elements. provided at both ends. In this case, one of the faces places 11a and 12a of the textile panels 11 and 12 may be coated with a primer providing, in addition to impermeability to water, a pleasant touch.

Fixing means 50 may also be provided on the cover 2 and on a corresponding mattress 41 so as to secure the inflated cover 2 as a pillow along its edge 21 at the edge 411 of said mattress (Figure 5). These fastening means 50 are for example two complementary ribbons type self-gripping loops and hooks or include snaps. They are arranged on said cover and said mattress so that the pillow is in line with said mattress 41 whose size does not provide a location for the hiker's head. The said mattress 41 is thus less bulky and lighter than a conventional mattress. The mattress 41 may be an inflatable mattress or foam.

In a second example of a coating assembly, not shown, the only air exhaust element is the introduction opening. In this case, unlike the cover 2 shown in Figures 1 to 5, the cover has no valve. Preferably, closure means of the hook and loop type, in the form of two complementary ribbons, are arranged inside the cover and at a distance from the insertion opening so as to leave the portion of the cover adjacent to the introduction opening adapted to be wound on the transverse strap without creating extra thickness due to said closure means. In addition, said closure means allow, during the compression step, to evacuate the air in the sleeping bag and the cover while preventing the sleeping bag from leaving the cover. During the compressive winding of the coating assembly on itself towards the insertion opening, the complementary fastening members are pressed against one another causing the airtight closure of the introductory opening. Once the expelled air and the coating assembly have a mean thickness E1, the fasteners provided at the ends of the cross strap are closed to form a carrying handle of the assembly.
