Description

La présente invention a pour objet un procédé et un dispositif de conditionnement d'un vêtement isothermique.The present invention relates to a method and a device for packaging an isothermal garment.

On connaît des vêtements isothermiques plus particulièrement dénommés "doudoune". Ces vêtements généralement des vestes sont constitués d'une feuille de tissu en matière synthétique de très faible épaisseur laissant passer l'air, une couche de matériau isolant et réflecteur de chaleur du type fibres artificielles ou mieux encore une couche de duvet naturel, une feuille de tissu en matière synthétique laissant passer l'air et les molécules d'eau mais imperméable à l'eau sous forme de gouttes, cet effet étant obtenu par dépôt d'un voile polymère hydrophobe.Isothermal clothing is more particularly known as "down jacket". These garments, generally jackets, consist of a very thin sheet of synthetic material allowing air to pass through, a layer of insulating and heat reflective material of the artificial fiber type or better still a layer of natural down, a sheet of synthetic material fabric allowing air and water molecules to pass through but impermeable to water in the form of drops, this effect being obtained by depositing a hydrophobic polymeric veil.

L'effet de matelassage est obtenu par des surpiquages traversant qui isolent des volumes de dimensions réduites. Ceci présente un double avantage tout d'abord celui d'une meilleure répartition de la matière isolante et ensuite évite en cas de déchirure de perdre l'ensemble de la matière isolante.The quilting effect is obtained by cross stitching which insulates volumes of reduced dimensions. This has a double advantage first of all that of a better distribution of the insulating material and then avoids in case of tearing to lose all of the insulating material.

Le fonctionnement de la matière isolante est en fait dû à un emprisonnement d'une couche d'air grâce au volume apparent crée par le duvet et c'est cette couche d'air qui est isolante.The functioning of the insulating material is in fact due to a trapping of a layer of air thanks to the apparent volume created by the down and it is this layer of air which is insulating.

Le duvet présente l'avantage également d'avoir une densité très faible et un caractère élastique qui assure un bon gonflement.Down also has the advantage of having a very low density and an elastic character which ensures good swelling.

Ce type de vêtement présente tous les avantages du point de vue thermique mais il implique un inconvénient important corollaire de ses qualités: son volume est important. On comprend que cet inconvénient devient un problème lorsque la place est comptée comme dans le sac des alpinistes, dans les trousses de secours, dans les refuges, sur les bateaux et avions par exemple.This type of garment has all the advantages from the thermal point of view, but it involves an important drawback which is a corollary of its qualities: its volume is important. We understand that this drawback becomes a problem when space is counted as in the bag of mountaineers, in first aid kits, in shelters, on boats and planes for example.

De plus, il est nécessaire qu'une fois pliée cette veste soit rapidement accessible.In addition, it is necessary that once folded this jacket be quickly accessible.

Il a été proposé de placer ce type de vêtement dans des emballages sous vide puisqu'en effet c'est l'air qui prend le plus grand volume.It has been proposed to place this type of garment in vacuum packaging since it is indeed the air which takes up the largest volume.

Une telle méthode est susceptible de critiques. Il faut en effet disposer d'une installation de mise sous vide et la méthode ne peut pas être appliquée n'importe où en plus du prix de revient.Such a method is open to criticism. It is indeed necessary to have a vacuum installation and the method cannot be applied anywhere in addition to the cost price.

Lors du transport on peut craindre des accrocs sur l'emballage, ce qui est probable compte tenu des utilisations, et un seul accroc est suffisant.During transport there is a risk of snags on the packaging, which is likely given the uses, and a single snag is sufficient.

Le plus grave est surtout l'effet endothermique lors de l'utilisation. En effet, étant mis sous vide, il n'y a qu'une fraction d'air résiduel très faible dans le matelassage. L'effet de gonflement élastique de duvet est progressif et lorsque l'utilisateur a enfilé sa veste c'est sa propre chaleur qui est "pompée" par le gonflement du matelassage. On comprend donc que l'effet isolant nécessaire dès le départ est inversé.The most serious is especially the endothermic effect during use. Indeed, being evacuated, there is only a very small fraction of residual air in the quilting. The elastic swelling effect of down is progressive and when the user has put on his jacket it is his own heat which is "pumped" by the swelling of the quilting. We therefore understand that the insulating effect necessary from the start is reversed.

L'invention a donc pour but de proposer un dispositif de conditionnement d'un vêtement isothermique selon la revendication 1, et un procédé de pliage d'un vêtement isothermique conformément à la revendication 3.The invention therefore aims to provide a device for packaging an isothermal garment according to claim 1, and a method of folding an isothermal garment according to claim 3.

La veste ainsi pliée est immédiatement utilisable après extraction du sac qui est obtenue par retrait par traction de la broche de verrouillage, ouverture de la fermeture rapide, retrait des élastiques.The jacket thus folded is immediately usable after extraction of the bag which is obtained by pulling out the locking pin, opening the quick fastener, removing the elastics.

Ce type de veste trouve une application certaine dans les nécessaires de survie en régions froides.This type of jacket finds a certain application in survival kits in cold regions.

L'invention va maintenant être décrite suivant un mode de réalisation non exhaustif en relation avec les figures annexées qui représentent:

The invention will now be described according to a non-exhaustive embodiment in relation to the appended figures which represent:
Figure 1:

Figure 7:
Installation of the locking pin.

Sur la figure 1, on a représenté une veste isothermique dépliée 1, dont on distingue la capuche 2, le col 3, des manches 4′ et 4˝ et la veste proprement dite 4. Elle est constituée de deux feuilles de matériaux synthétiques très fines entre lesquelles est disposé généralement du duvet naturel ou un autre matériau isolant en fibres (non figuré). Des surpiquages 5 sont effectués pour délimiter des volumes 6 assurant une bonne répartition du duvet.In Figure 1, there is shown an unfolded insulated jacket 1, which distinguishes the hood 2, the collar 3, sleeves 4 ′ and 4˝ and the jacket itself 4. It consists of two sheets of very fine synthetic materials between which is generally placed natural down or another insulating fiber material (not shown). Topstitching 5 is carried out to delimit volumes 6 ensuring good distribution of the down.

Sur la figure 2, on voit un boudin 7 réalisé par roulage de la veste dans le sens de la flèche 8 indiquée figure 1 c'est-à-dire de la capuche vers le bas.In Figure 2, we see a flange 7 produced by rolling the jacket in the direction of the arrow 8 indicated in Figure 1, that is to say from the hood down.

Des liens de serrage temporaire 9 assurent le maintien en forme du boudin 7. On dispose alors le boudin parallèlement à un gabarit 10 qui indique la position des bracelets élastiques de serrage fixes 11 tels que montré figure 3.Temporary tightening links 9 maintain the shape of the tube 7. The tube is then placed parallel to a template 10 which indicates the position of the elastic fixed tightening bracelets 11 as shown in FIG. 3.

Ces élastiques sont en effet positionnés à des distances bien précises de chaque extrémité du boudin pour permettre un pliage de ce boudin en forme de double rectangle concentrique comme représenté à la figure 4. Des bracelets élastiques supplémentaires 18 maintiennent la veste dans la position lovée. Les drisses de conditionnement telles que 20 sont passées au travers des plis du boudin. Dans l'exemple schématisé figure 4, la trousse 30 comporte 15 drisses de conditionnement régulièrement réparties plus particulièrement équidistantes les unes des autres ainsi qu'avec le bord de la trousse de conditionnement 30 dont on a représenté la face inférieure 31 bordée d'une partie de fermeture rapide 310. Sur la figure 5 on a placé la face supérieure 32 munie de 15 oeillets 33 régulièrement répartis pour se trouver à l'aplomb de chaque drisse qui est alors passée à travers chaque oeillet.These elastic bands are in fact positioned at very precise distances from each end of the tube to allow folding of this tube in the form of a concentric double rectangle as shown in FIG. 4. Additional elastic straps 18 hold the jacket in the coiled position. Conditioning halyards such as 20 are passed through the folds of the sausage. In the example shown diagrammatically in FIG. 4, the kit 30 comprises 15 conditioning halyards regularly distributed more particularly equidistant from one another as well as with the edge of the conditioning kit 30, the underside 31 of which is shown bordered with a part rapid closure 310. In FIG. 5, the upper face 32 is placed provided with 15 eyelets 33 regularly distributed so as to be in line with each halyard which is then passed through each eyelet.

Sur l'agrandissement d'une portion de la figure 5, on a fait abstraction de la face supérieure et du boudin pour montrer que les drisses de conditionnement sont temporaires elles sont simplement introduites dans une boucle 34 qui, elle, est cousue en 35 ou du moins solidaire de la face inférieure 31 de la trousse 30.On the enlargement of a portion of Figure 5, we have disregarded the upper face and the flange to show that the conditioning halyards are temporary they are simply introduced into a loop 34 which is sewn in 35 or at least secured to the underside 31 of the kit 30.

La face supérieure 32 est également bordée par une partie de fermeture rapide 311 symétrique à la partie 310. La trousse figure 6 est fermée pour former un volume grâce à la fermeture rapide et par pliage des rabats 36 et 37. Parallèlement on tire sur chaque drisse de façon à faire apparaître la boucle à travers l'oeillet et l'on passe alors la drisse de la boucle adjacente dans la première boucle de façon à ce que les boucles adjacentes se maintiennent les unes avec les autres sans nécessité d'un noeud. Le montage est représenté de façon agrandie par les boucles 60 et 61. La boucle 60 passe à travers l'oeillet 62 et la boucle 61 passe à travers l'oeillet 63 et dans la boucle 60 ce qui maintient alors cette boucle 60. La longueur de la boucle est calculée pour que la tension soit suffisante mais possible.The upper face 32 is also bordered by a quick closing part 311 symmetrical to the part 310. The kit in FIG. 6 is closed to form a volume thanks to the quick closing and by folding the flaps 36 and 37. At the same time, each halyard is pulled. so as to make the loop appear through the eyelet and the halyard of the adjacent loop is then passed through the first loop so that the adjacent loops are maintained with each other without the need for a knot. The assembly is shown in an enlarged manner by the loops 60 and 61. The loop 60 passes through the eyelet 62 and the loop 61 passes through the eyelet 63 and into the loop 60 which then maintains this loop 60. The length of the loop is calculated so that the tension is sufficient but possible.

Sur la figure 7 on a montré la boucle centrale 70 que l'on fait passer dans les deux boucles adjacentes 71 et 72. La longueur de la boucle 70 est prévue pour être juste dépassante au-dessus de l'oeillet correspondant 73 de façon à ce que l'on puisse y introduire la broche de verrouillage 74. Celle-ci peut être reliée à une sangle (non représentée) solidaire de la trousse de façon à faciliter la traction ultérieure.In FIG. 7, the central loop 70 has been shown which is passed through the two adjacent loops 71 and 72. The length of the loop 70 is provided to be just protruding above the corresponding eyelet 73 so as to that we can introduce the locking pin 74. This can be connected to a strap (not shown) integral with the kit so as to facilitate subsequent traction.

De même la broche de verrouillage peut être maintenue en place par un lien de sécurité qui se brise aisément sous l'effet d'une traction mais qui limite les possibilités de désengagement intempestif de la broche. Une telle trousse permet de conditionner une veste d'un poids de 1135 g pour adulte dans un volume de

Longueur
375 mm
Largeur
270 mm
Hauteur
60 mm


pour un poids supplémentaire de 215 g.Similarly, the locking pin can be held in place by a safety link which breaks easily under the effect of a traction but which limits the possibilities of inadvertent disengagement of the pin. Such a kit makes it possible to package a jacket weighing 1135 g for adults in a volume of
Length
375 mm
Width
270 mm
Height
60 mm


for an additional weight of 215 g.

La présente invention n'est pas limitée aux exemples de réalisation qui viennent d'être décrits, elle est au contraire susceptible de modifications et de variantes qui apparaîtront à l'homme de l'art.The present invention is not limited to the exemplary embodiments which have just been described, it is on the contrary liable to modifications and variants which will appear to those skilled in the art.
