Abstract

A sleeping bag comprises a lightweight layer (2) made from a material with a low thermal insulation capacity like a sheet, and a heavyweight layer (1) of a material with a high insulation capacity, like a duvet, joined together round at least part of their edges by fastenings (8, 9). The fastenings can be in the form of seams, Velcro (RTM) strips or Zip (RTM) fasteners, or tongued and grooved interlocking plastic strips.

The fastenings can be in the form of seams, Velcro (RTM) strips or Zip (RTM) fasteners, or tongued and grooved interlocking plastic strips. The lightweight layer can have anti-static, water-repellent, anti-bacterial, deodorant or other treatments, and one corner of the sleeping bag can be fastened to a static object by an anti-theft cord and lock.

Description

Technical sector of the invention:

The present invention relates to the technical sector of sleeping.

Prior art:

We naturally know many sleeping bags for the camping and generally recreation, of the “down” type or analogs, well known to those skilled in the art.

In the area of night passenger transport, by air, sea or passengers are given blankets.

These blankets, on the one hand do not provide great comfort, in all cases do not give the impression of comfort of a real bed, and other share do not give the passenger a choice based on temperature, personal habits, etc. The passenger is on or under the blanket, and it is often too hot in summer and cold in winter.

In addition, these covers are stolen in a very high proportion notable.

There is therefore an important and recognized need for a means of more sophisticated bedding which would bring comfort and possibility of choice and adapting to personal sleep patterns, and that would remain nevertheless of a cost compatible with the economic requirements of sector considered, which would be easily washable and storable, and which despite its appeal could not be easily stolen.

Summary of the invention:

The present invention relates to a reversible summer sleeping bag / winter (by “summer / winter”, here we mean by simplicity that the user can adapt the use he makes of the bag to the ambient temperature and its personal habits; "Summer / winter" therefore also means more general "warm bed / cool bed" and even "bed light / heavy bedtime ", some people want to sleep with a feeling of "weight" on the body, especially the legs or feet, even in "summer" or in a temperate or warm atmosphere) which combines a summer side with a sheet above and a winter side with a warm element such as blanket, quilted element, "quilt" and elements of this type well known (hereinafter "quilt" for simplicity).

Detailed description of the invention:

• un élément de couchage 2 léger et à faible caractéristique d'isolation thermique ; superposé ou sensiblement superposé à
• un élément de couchage 1 lourd et à forte caractéristique d'isolation thermique ;
• les deux éléments étant réunis ensemble, sur au moins une partie de leur pourtours superposés a, b et c, par des moyens de réunion 8, 9 ou 50.

The invention therefore relates to a reversible sleeping bag "summer / winter" in the broad sense defined above, which combines at least:

• a light sleeping element 2 with a low thermal insulation characteristic; superimposed or substantially superimposed on
• a heavy sleeping element 1 with a high thermal insulation characteristic;
• the two elements being joined together, on at least part of their superimposed edges a, b and c, by means of assembly 8, 9 or 50.

By "light" here is meant by simplicity all fabrics, non-woven, and similar thin and light structures, including sheets.

By “heavy” here we mean by simplicity heavier structures, like a more or less thick blanket, a more or less "down" thinner, a more or less thick “duvet”, and the like.

By “low thermal insulation characteristic”, we mean here the fact that said thin structure is not intended to provide a feeling heat to the user, and has the function of providing comfort contact, and a slight or very slight thermal protection.

By “strong thermal insulation characteristic”, we mean here the fact that said thicker structure has the function of providing a feeling of warmth (more or less intense depending on the thickness, selected materials, etc.) to the user, and additionally a function to provide comfort in contact, as well as possibly support comfort due to its thickness or character fleece or the like.

The skilled person will obviously understand without any difficulty the scope of the definitions which have just been given, without limitation.

Said meeting means 8, 9 or 50 are fixed and / or removable, and consist of a seam 50 (or other continuous meeting mode such as a Velcro ™ hook band or a zipper ™ or or a double plastic strip 55, 60 with groove 62 / groove 55 nestable by pressure as described in Figure 5, and the like) or in buttons pressure 8, 9 of which the male part is located on the edge of one of the elements 1 or 2 and the female element on the other element 2 or 1, naturally in look of the first.

The meeting by any means of meeting is continuous or discontinuous or semi-continuous, and according to a preferred embodiment, the meeting facilities will be arranged on parts a and b of the perimeter, by providing an opening c where there are no means of meeting.

According to a preferred embodiment, as shown in FIG. 1, a seam 50 or other means of continuous joining is provided on the periphery of the "bottom" of the bag, ie the periphery a between the points A and B, and press studs 8, 9 on the delimited lateral edges on each side of the bag by the points AF and respectively BF, in leaving an opening c between points F at the "front" of the bag.

According to yet another preferred embodiment, the “front” end of the bag, on the side of the opening c, has a flap 4 whose edges 5 side are joined together by means of meeting such as described above, in particular press buttons 6, 7.

In the winter position shown in Figure 1 or Figure 3, this flap is thin and does not interfere; however, it can be flat by opening buttons 6, 7.

In the summer position, i.e. element 1 below and element 2 below (fig. 4) it forms a flap comparable to the usual sheet flaps and provides therefore a feeling of comfort.

According to a particular embodiment (FIG. 6), the corners F may further comprise meeting means 70 passing through either element 1 either element 2 or both (they are in the lateral position and therefore do not interfere with the subject, capable of cooperating with a means of compatible meeting 75 mounted on a leg 77, an inflatable element 78 (provided with an inflation means 79) being fixed to the other end of tab 77, said joining means 70, 75 being by example Velcro ™ bands or snaps.

According to a preferred embodiment, at least one corner C (or another appropriate location, depending on the intended application, includes a set of anti-theft means (FIG. 2) to be implemented possibly for public transport, especially on the network rail or maritime lines where effective surveillance cannot not be materially insured given the large number of passenger by oar or ship, or in campsites, caravans, inns or country cottages etc .....

The anti-theft system has a solid strap that is difficult to cut (for example example in reinforced plastic or Kevlar ™) 11 fixed by a seam or other similar means 12 not removable in the area of the corner C (or other suitable location) of the bag, and this strap has a latch 14 can only be opened with a special key, capable of cooperating in closing and opening mode with a plate or other tip 15 to snap into latch 14, said end piece 15 being fixed at the end a second strap 13 fixed at its other end to the latch 14, and capable of forming a loop that can be positioned around a solid fixed element secured to the vehicle; and still has an area 16 surrounding the seam 12 (delimited on the element 1 and on the element 2 and also protecting the thickness between the two superimposed elements and the seam 50, the delimitation of the zone being such that, to remove the anti-theft system 10, the user would have to cut a completely element 1 and element 2 deterrent, i.e. making the bag unusable) and whose two sides form a protective "shell" cannot be cut by usual means such as scissors, cutters or analogs, said shell 16 being for example made of Kevlar ™ or analogous material.
