Definitions

• 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.
• 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.
• 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.
• 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.
• 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:
• the assembly 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.
• 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.
• cover / sleeping bag 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.
• 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.
• the assembly 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.
• 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.
