Abstract

A backpack having a front panel normally riding on the back of the wearer according to this invention has a front panel which is vertically elongated and which is formed of an at least semirigid shell having a shape generally complementary to that of the back of the wearer and constucted to be relatively bendable longitudinally and relatively stiff transversely. Thus the panel can bend forward and back, that is about a horizontal axis, but cannot flex about a vertical axis. This is achieved by forming the shell with transverse rigidifying formations so it is longitudinally relatively bendable and transversely relatively stiff. These formations according to this invention are ridges or grooves.

Description

Si l'on considère l'agencement de leurs dos, les sacs à dos peuvent être divisés en trois catégories principales : ceux ne comportant aucune armature, ceux équipés d'une armature rigide et ceux munis de barrettes semi-rigides à disposition longitudinale.If we consider the arrangement of their backs, backpacks can be divided into three main categories: those with no frame, those with a rigid frame and those with semi-rigid bars with longitudinal arrangement.

Les sacs sans armature sont légers ; mais ils nécessitent que le sac soit chargé de façon ordonnée et soignée pour éviter que certains objets constituent par trop une gêne ; et surtout ils ont pour inconvénient, notamment si leur charge est mal répartie, de très mal épouser la forme du dos humain et donc de ne pas être suffisamment solidaires du dos du porteur.The bags without frame are light; but they require that the bag be loaded in an orderly and neat way to avoid that certain objects constitute too much an embarrassment; and above all they have the drawback, especially if their load is poorly distributed, of very badly marrying the shape of the human back and therefore of not being sufficiently integral with the back of the wearer.

Les sacs avec armature intégrale rigide n'ont pas ces inconvénients ; mais ils sont lourds et, du fait qu'ils sont rigides à la fois longitudinalement et transversalement, ils s'opposent à ce que le sac accompagne le mouvement du corps lorsque le dos du porteur fléchit. Il s'agit là d'un grave inconvénient. dans de nombreux cas, notamment par exemple lorsque le sac est utilisé en escalade ou en randonnée à ski.Bags with rigid integral frame do not have these disadvantages; but they are heavy and, because they are rigid both longitudinally and transversely, they prevent the bag from accompanying the movement of the body when the back of the wearer flexes. This is a serious drawback. in many cases, especially for example when the bag is used in climbing or ski touring.

Les sacs dont le dos est muni de barrettes semi-rigides longitudinales ne présentent pas ces inconvénients ; mais par contre, en raison de leur manque total de rigidité transversale, ils n'épousent pas réellement la forme du dos humain et n'adhèrent ainsi pas suffisamment au dos ; ils peuvent donc donner lieu à un certain ballottement latéral.Bags whose back is provided with longitudinal semi-rigid bars do not have these drawbacks; but on the other hand, due to their total lack of transverse rigidity, they do not really follow the shape of the human back and thus do not adhere sufficiently to the back; they can therefore give rise to a certain lateral sloshing.

En réalité, il n'existe pas un type de dos de sac garantissant à la fois une bonne tenue et un bon contact du sac avec le dos, y compris lors des mouvements de flexion du dos du porteur.In reality, there is no type of bag back guaranteeing both good hold and good contact of the bag with the back, including during flexion movements of the wearer's back.

L'invention pallie cette lacune. Elle a pour objet un sac à dos dont le dos est équipé d'une coque intérieure qui présente un profil et des dimensions correspondant sensiblement à ceux du dos humain et qui est rigide transversalement, mais flexible longitudinalement.The invention remedies this shortcoming. It relates to a backpack whose back is equipped with an inner shell which has a profile and dimensions corresponding substantially to those of the human back and which is rigid transversely, but flexible longitudinally.

Divers modes de réalisation peuvent être envisagés pour cette coque. C'est ainsi que, suivant une forme d'exécution, elle est constituée par une feuille de matière plastique préformée dont la face arrière, dirigée vers le corps du sac, présente des nervures transversales. Ces nervures donnent à la coque la rigidité transversale recherchée, mais ne s'opposent pas à sa déformation dans le sens longitudinal.Various embodiments can be envisaged for this shell. Thus, according to one embodiment, it is constituted by a sheet of preformed plastic material whose rear face, directed towards the body of the bag, has transverse ribs. These ribs give the hull the desired transverse rigidity, but do not oppose its deformation in the longitudinal direction.

Dans une forme d'exécution de l'invention, cette coque ne constitue pas à elle seule le dos du sac. C'est donc ainsi que le dos du sac peut être constitué en combinaison par cette coque, par une doublure recouvrant sa face intérieure au sac, par une couche de matériau cellulaire recouvrant sa face extérieure et par un tissu de recouvrement extérieur. Ce tissu peut être rapporté par couture sur et autour de l'ensemble ; mais il peut aussi s'agir d'un tissu lié par collage avec le matériau cellulaire sous-jacent ou d'un tissu sur lequel ce matériau est moulé.In one embodiment of the invention, this shell does not in itself constitute the back of the bag. This is how the back of the bag can be formed in combination by this shell, by a lining covering its inside face to the bag, by a layer of cellular material covering its outside face and by an outside covering fabric. This fabric can be added by sewing on and around the set; but it can also be a fabric bonded by bonding with the underlying cellular material or a fabric on which this material is molded.

Dans une autre forme d'exécution, la coque constitue réellement le dos du sac, sans nécessiter d'être associée à d'autres éléments. Dans ce cas, la coque est constituée par au moins deux couches de matière cellulaire surmoulées l'une sur l'autre et dont celle intérieure au sac possède une densité plus forte que celle extérieure et comporte des rainures et nervures lui conférant respectivement sa flexibilité longitudinale et sa rigidité transversale. Au dos ainsi agencé est associé un élément souple extérieur en tissu ou en jersey sur lequel est moulée la couche extérieure cellulaire de faible densité entrant dans la constitution du dos.In another embodiment, the shell actually constitutes the back of the bag, without needing to be associated with other elements. In this case, the shell is made up of at least two layers of cellular material overmolded one on top of the other and the inner layer of the bag has a higher density than the outer one and has grooves and ribs giving it respectively its longitudinal flexibility. and its transverse rigidity. On the back thus arranged is associated a flexible external element of fabric or jersey on which is molded the cellular outer layer of low density entering into the constitution of the back.

L'invention sera bien comprise d'ailleurs, à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemples non limitatifs, deux formes d'exécution d'un tel dos :

  • Figure 1 est une vue en perspective arrière d'un sac équipé de ce dos,
  • Figures 2 et 3 sont des vues respectivement de face et de côté en élévation de la coque du dos, dans le cas de la première forme d'exécution,
  • Figures 4 et 5 en sont, à plus grande échelle, des vues en coupe respectivement suivant IV-IV et V-V de figure 3,
  • Figure 6 montre la coque, de côté en élévation, lorsqu'elle est soumise à un mouvement de flexion longitudinale,
  • Figure 7 est, à plus grande échelle, une vue partielle en coupe transversale du dos dans lequel cette coque est intégrée,
  • Figures 8 et 9 illustrent en perspective une deuxième forme d'exécution du dos de sac, vu respectivement à partir de l'intérieur et à partir de l'extérieur du sac, et
  • Figure 10 est, à plus grande échelle, une vue en coupe horizontale suivant X-X de figure 8.
The invention will moreover be clearly understood, with the aid of the description which follows, with reference to the appended schematic drawing representing, by way of nonlimiting examples, two embodiments of such a back:
  • FIG. 1 is a rear perspective view of a bag fitted with this back,
  • FIGS. 2 and 3 are respectively front and side views in elevation of the back shell, in the case of the first embodiment,
  • FIGS. 4 and 5 are, on a larger scale, sectional views respectively along IV-IV and VV of FIG. 3,
  • Figure 6 shows the shell, side elevation, when subjected to a longitudinal bending movement,
  • FIG. 7 is, on a larger scale, a partial view in cross section of the back in which this shell is integrated,
  • FIGS. 8 and 9 illustrate in perspective a second embodiment of the back of the bag, seen respectively from the inside and from the outside of the bag, and
  • FIG. 10 is, on a larger scale, a view in horizontal section along XX of FIG. 8.

A la figure 1, 1 désigne, de façon générale, un sac à dos dont l'agencement d'ensemble ainsi que la forme et les dimensions peuvent être quelconques ; et 2 désigne, de façon générale, le dos de ce sac, dos qui en constitue l'élément original.In FIG. 1, 1 designates, in general, a backpack whose overall arrangement as well as the shape and the dimensions can be any; and 2 denotes, in general, the back of this bag, which constitutes the original element.

Dans le cas de la forme d'exécution des figures 2 à 7, le dos 2 comporte une coque intérieure 3 qui est réalisée en une feuille de matière plastique préformée de manière à présenter, au moins approximativement, le profil du dos humain. Ce préformage est avantageusement obtenu par moulage d'une seule et même feuille de matière plastique ; mais il pourrait être obtenu en assemblant par tout moyen approprié, notamment par soudure ou par collage, diverses feuilles de matière plastique ayant été préalablement découpées de manière telle que leur assemblage permette d'obtenir la forme recherchée.In the case of the embodiment of Figures 2 to 7, the back 2 has an inner shell 3 which is made of a plastic sheet preformed so as to present, at least approximately, the profile of the human back. This preforming is advantageously obtained by molding a single sheet of plastic material; but it could be obtained by assembling by any suitable means, in particular by welding or by gluing, various sheets of plastic material having been cut beforehand so that their assembly makes it possible to obtain the desired shape.

Cette coque 3 qui est constituée par une mince feuille de matière plastique est déformable ; mais elle présente pour particularité d'être munie de nervures 4 s'étendant horizontalement sur sa face arrière. Ces nervures sont avantageusement obtenues par moulage avec la coque elle-même. Grâce à elles, la coque présente une certaine rigidité transversale, alors qu'elle conserve ses possibilités de flexion dans le sens longitudinal. Il en résulte que la présence de la coque 3 permet au dos du sac d'épouser parfaitement le dos du porteur et ce, dans toutes les circonstances, y compris pendant les mouvements de flexion du dos vers l'avant. Le fait que la coque 3 est rigide transversalement garantit, en outre, que le sac ne risque pas de ballotter latéralement sur le dos.This shell 3 which is constituted by a thin sheet of plastic material is deformable; but it has the particularity of being provided with ribs 4 extending horizontally on its face back. These ribs are advantageously obtained by molding with the shell itself. Thanks to them, the shell has a certain transverse rigidity, while it retains its possibilities of bending in the longitudinal direction. It follows that the presence of the shell 3 allows the back of the bag to perfectly fit the back of the wearer and this, in all circumstances, including during backward bending movements. The fact that the shell 3 is rigid transversely guarantees, moreover, that the bag does not risk tossing laterally on the back.

Les modes de montage de la coque 3 à l'intérieur du dos 2 du sac peuvent être quelconques ; et c'est ainsi qu'à titre d'exemple, comme le montre la figure 7, la coque 3 peut être recouverte par une couche d'un matériau cellulaire 5 s'étendant sur sa face extérieure, alors que sa face intérieure est revêtue par un tissu ou autre élément de doublure 6. La face extérieure de la couche de matériau cellulaire 5 est elle-même revêtue d'un tissu ou autre élément 7 qui sera en contact avec le dos du porteur.The mounting methods of the shell 3 inside the back 2 of the bag can be any; and this is how, for example, as shown in FIG. 7, the shell 3 can be covered by a layer of cellular material 5 extending on its outer face, while its inner face is coated by a fabric or other lining element 6. The outer face of the layer of cellular material 5 is itself coated with a fabric or other element 7 which will be in contact with the back of the wearer.

Dans le cas de la variante d'exécution représentée aux figures 8 à 10, le dos 2 du sac vient de moulage en une seule pièce ; mais il est en réalité composé de trois éléments, à savoir deux couches de résine synthétique cellulaire respectivement 8 et 9 et un jersey 10. Ces trois éléments sont liés entre eux par moulage de deux résines, après que le jersey 10 ait été mis en place dans le moule. Les deux couches de résine cellulaire surmoulées ont des propriétés différentes. Celle 8, qui est destinée à former l'élément intérieur du dos du sac, présente une densité relativement forte ; elle est constituée, par exemple, par une résine de polyu- réthane ayant une densité de 300 kg au m3. Celle 9, qui est destinée à former l'élément extérieur du dos, présente au contraire une densité beaucoup plus faible ; elle constitue, par exemple, en une résine de polyether ayant une densité de 30 kg au m3. La couche de résine 8 constitue le corps du dos ; la couche de résine 9 constitue un élément de confort au contact du dos ; et la face extérieure de cette couche 9 est revêtue du jersey 10 qui augmente le confort et protège la couche de résine.In the case of the alternative embodiment shown in Figures 8 to 10, the back 2 of the bag is molded in one piece; but it is actually composed of three elements, namely two layers of cellular synthetic resin 8 and 9 respectively and a jersey 10. These three elements are linked together by molding two resins, after the jersey 10 has been put in place in the mold. The two layers of overmolded cellular resin have different properties. That 8, which is intended to form the inner element of the back of the bag, has a relatively high density; it is constituted, for example, by a polyurethane resin having a density of 300 kg per m 3 . That 9, which is intended to form the outer element of the back, on the contrary has a much lower density; it constitutes, for example, a polyether resin having a density of 30 kg per m 3 . The resin layer 8 constitutes the body of the back; the resin layer 9 constitutes an element of comfort in contact with the back; and the outer face of this layer 9 is coated with jersey 10 which increases comfort and protects the resin layer.

Pour que la couche de résine dense 8 constituant le corps du dos confère à ce dos la flexibilité longitudinale et la rigidité transversale qui sont recherchées, cette couche 8 comporte, venant de moulage, une alternance de nervures et de rainures horizontales respectivement 12 et 13. Pour atteindre le but recherché, ces nervures et rainures sont avantageusement associées à des différences d'épaisseur dans la couche de résine 8, lesquelles différences d'épaisseur peuvent donner lieu à la formation de nervures verticales 14 s'étendant sur tout ou partie de la hauteur du dos.So that the dense resin layer 8 constituting the body of the back gives this back the longitudinal flexibility and the transverse rigidity which are sought, this layer 8 comprises, coming from molding, an alternation of ribs and horizontal grooves 12 and 13 respectively. To achieve the desired goal, these ribs and grooves are advantageously associated with differences in thickness in the resin layer 8, which differences in thickness can give rise to the formation of vertical ribs 14 extending over all or part of the back height.

Si la couche de résine dense 8 constituant le corps du dos est réalisée dans des conditions de moulage telles qu'une peau 15 se forme à la surface de la couche de résine 8, il est inutile de prévoir, à l'intérieur du sac, un élément protecteur du dos. Bien plus, la peau 15 venant de moulage avec la couche de résine 8 peut être mise à profit pour servir à la liaison du dos du sac avec le corps du sac. Pour cela, la peau 15 présente une partie périphérique débordante 16 qui, revêtue successivement de la couche de résine peu dense 9 et du jersey 10 permet la liaison avec le tissu du corps du sac. Cette liaison peut être faite par couture comme désigné en 17 à la figure 10.If the dense resin layer 8 constituting the body of the back is produced under molding conditions such that a skin 15 is formed on the surface of the resin layer 8, it is unnecessary to provide, inside the bag, a protective element for the back. Furthermore, the skin 15 coming from molding with the resin layer 8 can be used to serve for the connection of the back of the bag with the body of the bag. For this, the skin 15 has an overhanging peripheral part 16 which, successively coated with the layer of low density resin 9 and jersey 10 allows the connection with the fabric of the body of the bag. This connection can be made by sewing as designated at 17 in FIG. 10.
