Definitions

• the present invention relates to the field of bags for the transport on foot of loads of modest weight, such as current domestic purchases (food, cleaning products, etc.).
• a backpack has the first two properties, but not the last two.
• saddlebag In an even more distant past, bags were used for the transport of moderate loads on foot.
• saddlebag is meant a bag split in the middle and closed at its ends, forming two pockets when worn astride the shoulder.
• the bags had to reconcile two contradictory criteria. On the one hand, they had to be made of a sufficiently thick and rigid material to resist 1 wear and the force exerted by the loads that can be housed there.
• the objective of the present invention is to provide a bag of large capacity, leaving the hands free, and which, in the empty state, is light and occupies a minimum volume, which it does in offering a new bag type bag, consisting of at least two layers of material, of the same shape and the same dimensions, superimposed and integral with each other along their periphery so as to define between them two pockets accessible by a median opening, said bag having a longitudinal direction and a transverse direction, and being characterized in that said opening is formed in the longitudinal direction of the bag and in that said material constituting at least one of the layers consists of a stretch fabric in the machine direction and / or in the cross direction.
• the median opening is provided, not transversely, as is the case in one prior art, but longitudinally.
• These two layers of the bag can be two separate pieces of material sewn together along their edges, a single piece of folded material in half on itself and sewn, or a single piece of tubular material.
• the opening is formed at the periphery of the bag.
• said opening may be located at one of the seam lines making the layers of material constituting the bag integral. In this way, the opening does not consist of an incision made in the fabric, but in a discontinuity of one of the seam lines, and the integrity, and therefore the resistance, of the fabric is not diminished.
• seam line we must understand here any type of attachment that can be made between the two layers, such as sewing, bonding, fusion, etc.
• the opening is provided directly by cutting along a generatrix of the tube.
• the second basic characteristic of the bag according to the invention is that it consists of a fabric that can be extended in the machine direction and / or in the cross direction.
• fabric here is meant both a material obtained by a weaving process, a material obtained by knitting, or even a non-woven material or a film.
• machine direction refers, in the case of woven materials, to the direction of the warp, in the case of knitted materials, to the direction of the columns of stitches, and in the case of non-woven and films in the direction of displacement of the sheet in formation in the production facility.
• cross direction refers to the direction which is perpendicular to the machine direction defined above.
• stretch fabric allows the bag to have a variable volume depending on whether it is empty or full.
• the stretch fabric advantageously has a weight per m 2 of between approximately 60 and 400 g / m, preferably 200 g / m.
• Satisfactory fabrics can consist of Lycra or fabrics composed of elastane, polyester and / or triacetate.
• the bag preferably deforms in one direction relative to the other.
• the loading of the bag does not lengthen it excessively, which could hamper walking, but rather gives it volume towards the front and towards the rear.
• Another measure to manage the shape of the bag in the loaded state is to use a material of relatively greater extensibility to form one of the walls of the bag and a material of more extensibility. weak or even not extensible to form the opposite wall, this latter wall being intended to come into contact with the wearer when the bag is thrown on his shoulder.
• Yet another possible measure to manage the shape of the bag when it expands and to reinforce it at its seams is to provide at least one strip of non-elastic material along the periphery of the layers of material making up the bag. bag, except, at least, in the transverse zone of the bag which contains the access opening to the pockets of the bag.
• said transverse zone of the bag which contains the access opening to the pockets of the bag can also be reinforced, but by a strip of elastic material whose elasticity can be substantially identical to that of the fabric, or slightly lower to stiffen and tighten the opening.
• this transverse area is devoid of reinforcing strip, on the one hand, so as not to alter the expansion capacity of the access opening to the pockets in order to their loading and, on the other hand, to give said transverse zone any latitude of extension under load, which thins it at the level of its contact with the shoulder, with the effect of improving the stability of the bag and of close the access opening to the pockets tightly.
• the bag according to the invention has a rectangular shape and, when empty, has a length of between approximately 70 and approximately 100 cm and a width of between approximately 40 and approximately 60 cm.
• the dimensions will be chosen, on the one hand, according to the average size of the intended user, adult or child, and on the other hand of the extensibility of the selected material.
• the opening will have a length between about 10 and about 20 cm, the chosen length depending on the size of the bag and the extensibility of the material.
• the length of the opening is relatively small (preferably, much less than the width of the bag, unlike what is found in the bags of the prior art) but the extensibility material allows items of relatively large size to enter the bag only by deformation of the opening.
• the bag according to the invention can take various forms and can consist of one or more pieces of fabric, joined together so as to form an enclosed space.
• the bag consists of a single piece of fabric folded back on itself so as to form a superposition of two layers of fabric, said two layers being sewn along their edges. free, however leaving an opening in the middle of the side opposite the side forming the fold line.
• a visual or tactile identification means can advantageously be associated with said opening.
• Such a locating means can consist, for example, of a strap, a braid or a border of a contrasting color, or of a material with a different feel, etc. it being understood that, whatever the means chosen, it must not alter the extensibility of the opening.
• FIG. 1 shows an embodiment of the bag according to the invention, flat and at empty
• 2 shows a partial section, on a larger scale, taken along line II-II of Figure 1
• Figure 3 illustrates the port of the bag of Figure 1 in one loaded state
• Figure 4 illustrates an alternative embodiment of a bag according to the invention, flat and empty
• Figure 5 illustrates another alternative embodiment of a bag according to the invention, flat and empty.
• the bag 1 according to the invention consists of a rectangular piece of stretchy fabric folded over on itself at its longitudinal median, thus determining two thicknesses of superimposed fabric E x and E 2 of lengths 2 and 3 and widths 4 and 5.
• the two thicknesses E x and E 2 are made integral with one another, by sewing, according to 6, along said widths 4 and 5 and said length 3, an unsewn area forming an opening 7, however, being provided.
• the free edges of the thicknesses of material E x and E 2 are turned inward and capped with a strip of non-elastic material 8, the whole being joined by two stitching lines 6a, 6b .
• This strip of material 8 strengthens the bag at the seams 6, removes the extensibility of the material of the bag at this same level and gives a good finish inside the bag.
• An elastic braid 9 of a contrasting color with respect to that of the bag borders the opening 7 so as to facilitate its location.
• the dimensions of the piece of stretch fabric used to make the bag may vary depending on the capacity and the desired use.
• the finished bag is in the form of a rectangle having, when empty, about 80 cm in length by about 45 cm in width, with an opening 7 of about 18 cm in length, these dimensions constituting only a nonlimiting example.
• the articles to be transported are introduced through the opening 7 by distributing them equitably in the pockets P x and P 2 so that the bag is balanced.
• the expansion capacity of the opening 7 allows relatively large objects to pass through it.
• FIG. 4 illustrates an alternative embodiment in which the bag is made up of a rectangular piece of fabric folded back on itself, no longer in two parallel folds and of the same width, as in FIG. 1, but in three parallel folds, the two outer folds having a width equal to half the width of the central fold and being folded over the central fold.
• the longitudinal seam 4 'of the bag in which the opening 7' is formed is therefore located along the median of one of the walls of the bag and not on an edge of the bag. It is of course understood that, in practice, the piece of fabric is folded in half as in FIG.
• the seam 4 ′ is created by making the opening 7 ′, the tubular piece thus obtained is placed so that the 6 'seam is placed at the median longitudinal of one of the layers and the ends are still sewn free by the seams 5 'and 6'.
• FIG. 5 illustrates another embodiment of the invention in which the bag 1 "consists of a single piece of tubular fabric sewn at its two free ends 5" and 6 ", in the width direction of the bag, the fabric being split lengthwise to create the 7 "opening.
• the bag can have another elongated and symmetrical shape around its transverse median axis, for example being in the shape of an hourglass.
• the bag instead of being in one piece, it can be made up of several pieces of fabric, possibly of different extensibility, sewn together or otherwise joined together.
