Description

Reversible sleeping bag summer / winter and

  its applications especially to travel.

  Technical sector of the invention The present invention relates to the technical sector of sleeping bags. PRIOR ART We naturally know many sleeping bags for camping and in general for leisure, 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 any case do not give the impression of comfort of a real bed, and on the other hand do not give the passenger the possibility of choice depending on the 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 more sophisticated sleeping means which would provide comfort and the possibility of choice and adaptation to personal sleep habits, and which would nevertheless remain at a cost compatible with the economic requirements of the 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 / winter sleeping bag (by "summer / winter", here for simplicity is meant that the user can adapt the use he makes of the bag to ambient temperature and to his personal habits, "summer / winter" therefore also means more generally "warm bed / cool bed" and even "light o10 bed / heavy bed", some people want to sleep with an impression of "weight" on the body , especially 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:

  The invention therefore relates to a reversible sleeping bag "summer / winter" in the broad sense defined above, which combines at least - a sleeping element 2 light and with 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 joining means 8, 9

or 50.

  By "light" here is meant for simplicity all fabrics, non-woven, and

  similar thin and light structures, including sheets.

  By <"heavy" here we mean by simplicity heavier structures, such as a more or less thick cover, a "down", more or

  thinner, a more or less thick "quilt", and the like.

  By "low thermal insulation characteristic", we mean here that said thin structure does not have the function of providing a feeling of warmth to the user, and has the function of providing comfort.

  contact, and a slight or very slight thermal protection.

  By "strong thermal insulation characteristic" is meant here the fact that said thicker structure has the function of providing a feeling of warmth (more or less intense depending on the thickness, the materials chosen, etc.) to the user, and additionally has the function of providing him with contact comfort, as well as optionally support comfort because of its thickness or its 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 joining means 8, 9 or 50 are fixed and / or removable, and consist of a seam 50 (or other continuous joining mode such as a VelcroTM hook strip or a zipperTM or or a double plastic strip 55, 60 with groove 62 / groove 55 push-fit as described in FIG. 5, and the like) or by press studs 8, 9 the male part of which 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 one of the meeting means is continuous or discontinuous or semi-continuous, and according to a preferred embodiment, the meeting means will be arranged on the parts a and b of the periphery, while providing an opening that does not find no meeting facilities. According to a preferred embodiment, as shown in Figure 1, there is provided a seam 50 or other means of continuous meeting around the periphery of the "bottom" of the bag, that is to say the periphery a between points A and B , and snaps 8, 9 on the lateral edges delimited on each side of the bag by the points AF and respectively BF, in

  leaving an opening c between the points F 1 ′ <before "of the bag.

  According to another preferred embodiment, the “front” end of the bag, on the side of the opening c, comprises a flap 4, the lateral edges 5 of which are joined together by means of assembly such as

  described above, in particular press buttons 6, 7.
