Description

La présente invention a pour objet un ensemble destiné à être porté au bras, par dessus un vêtement et comportant un instrument tel qu'une montre ou un localisateur de personnes en cas d'avalanche.The present invention relates to an assembly intended to be worn on the arm, over a garment and comprising an instrument such as a watch or a person locator in the event of an avalanche.

Dans la plupart des cas connus, les montres-bracelet sont portées au poignet, à même la peau. Dans certaines applications particulières, telles que des montres de plongée ou des montres destinées à des cosmonautes, on utilise des bracelets plus longs, afin de pouvoir porter la montre par dessus la combinaison de plongée ou la tenue spatiale. Ce mode de faire permet l'accès à l'information dans le courant de l'action.In most known cases, wristwatches are worn on the wrist, next to the skin. In certain particular applications, such as diving watches or watches intended for cosmonauts, longer straps are used, in order to be able to wear the watch over the diving suit or the space suit. This mode of access allows access to information during the course of the action.

Dans le cas où l'instrument est un localisateur de personnes, il a été constaté que non seulement celui-ci devait être porté par dessus le vêtement, mais qu'un des endroits les plus favorables se situe au voisinage immédiat du coude.In the case where the instrument is a locator of people, it has been found that not only must it be worn over the garment, but that one of the most favorable places is located in the immediate vicinity of the elbow.

Le fait de porter l'ensemble sur le vêtement à toutefois pour inconvénient que le risque d'accrochage avec l'environnement est important, à cause notamment du grand volume de la montre ou de l'instrument utilisé. Ceci peut avoir des effets désagréables voir désastreux. Si le bracelet ne tient pas solidement, il peut être arraché ou glisser le long du bras, ce qui peut conduire à la perte de l'instrument. Si au contraire le bracelet résiste à l'accrochage, la montre a tendance à basculer en prenant appui sur le vêtement. Il y a alors risque d'abîmer le vêtement et surtout de blesser le poignet sous-jacent.The fact of wearing the assembly on the garment, however, has the drawback that the risk of catching on with the environment is significant, in particular because of the large volume of the watch or of the instrument used. This can have unpleasant or even disastrous effects. If the bracelet does not hold securely, it can be torn off or slip along the arm, which can lead to the loss of the instrument. If, on the other hand, the bracelet resists snagging, the watch tends to tip over by leaning on the garment. There is then a risk of damaging the garment and especially of injuring the underlying wrist.

Le port d'un ensemble tel que définit ci-dessus, dans la pratique du ski, se pose avec d'autant plus d'acuité que le risque de chute est grand. La chute est généralement suivie d'une glissade durant laquelle les parties protubérantes sont susceptibles de s'accrocher. Ce problème devient vital lorsque le porteur est pris dans une avalanche et que l'instrument est un réflecteur destiné à localiser son porteur.Wearing a set as defined above, in skiing, arises with all the more acuity as the risk of falling is great. The fall is generally followed by a slide during which the protruding parts are likely to catch on. This problem becomes vital when the carrier is caught in an avalanche and the instrument is a reflector intended to locate its carrier.

Le but de la présente invention est de permettre la fixation de cet ensemble au bras du porteur, de manière agréable, tout en assurant une tenue en place aussi sûre que possible. Ce but est atteint grâce aux caractéristiques particulières que présente l'ensemble définit par la revendication 1.The object of the present invention is to allow the attachment of this assembly to the arm of the wearer, in a pleasant manner, while ensuring that it is held in place as secure as possible. This object is achieved thanks to the particular characteristics which the assembly defined by claim 1 has.

L'invention sera mieux comprise à la lecture de la description qui va suivre d'un dispositif selon l'invention, donnée à titre d'exemple et faite en référence au dessin dans lequel:

  • - la figure 1 représente ce dispositif porté au bras;
  • - les figures 2 et 3 sont des vues en plan respectivement en élévation du dispositif de la figure 1;
  • - les figures 4 et 5 sont respectivement des vues en coupe selon les lignes IV - IV et V - V de la figure 2;
  • - la figure 6 représente un ruban, partie du bracelet que comporte le dispositif représenté aux figures 1 à 5, vu du côté destiné à être porté sur le vêtement.
The invention will be better understood on reading the following description of a device according to the invention, given by way of example and made with reference to the drawing in which:
  • - Figure 1 shows this device carried on the arm;
  • - Figures 2 and 3 are plan views respectively in elevation of the device of Figure 1;
  • - Figures 4 and 5 are respectively sectional views along lines IV - IV and V - V of Figure 2;
  • - Figure 6 shows a ribbon, part of the bracelet that includes the device shown in Figures 1 to 5, seen from the side intended to be worn on the garment.

La figure 1 représente une partie d'un bras recouvert d'un vêtement, par exemple un anorak, sur lequel est fixé un dispositif selon l'invention. Ce dispositif comporte un instrument tel qu'une montre 10, un boîtier 12 destiné à entourer et assujettir cette montre, et un bracelet 14 pour fixer le boîtier et la montre 10 au bras. Ce bracelet entoure donc le bras par dessus le vêtement.FIG. 1 represents a part of an arm covered with a garment, for example an anorak, on which a device according to the invention is fixed. This device comprises an instrument such as a watch 10, a case 12 intended to surround and secure this watch, and a strap 14 for fixing the case and the watch 10 to the arm. This bracelet therefore surrounds the arm over the garment.

Ainsi qu'on peut le voir de manière plus précise sur les figures 2 à 5, le boîtier 12 est réalisé au moyen de deux coques 16 et 18, avantageusement en Delrin (marque déposée), soudées l'une à l'autre par friction. Vu de dessus, le boîtier 12 a la forme générale d'un rectangle sur l'un des grands côtés duquel un demi-cercle est accolé. La partie centrale du boîtier 12 comporte une ouverture circulaire 20 concentrique au demi-cercle et destinée à recevoir la montre 10.As can be seen more precisely in Figures 2 to 5, the housing 12 is made by means of two shells 16 and 18, advantageously in Delrin (registered trademark), welded to each other by friction . Seen from above, the housing 12 has the general shape of a rectangle on one of the long sides of which a semicircle is joined. The central part of the housing 12 has a circular opening 20 concentric with the semicircle and intended to receive the watch 10.

Les deux coques 16 et 18 du boîtier définissent entre elles un logement 22 destiné à recevoir un second instrument, un réflecteur d'ondes électromagnétiques 24 tel que décrit par exemple dans la demande de brevet EP 0 172 445, qui permet la recherche de personnes dans les avalanches.The two shells 16 and 18 of the housing define between them a housing 22 intended to receive a second instrument, an electromagnetic wave reflector 24 as described for example in patent application EP 0 172 445, which allows the search for people in avalanches.

La coque inférieure 18 du boîtier 12 porte sur sa face extérieure deux renflements 28 définissant des fentes 30 au travers desquelles passe le bracelet 14.The lower shell 18 of the housing 12 carries on its outer face two bulges 28 defining slots 30 through which the bracelet 14 passes.

Ainsi qu'on peut le voir sur les figures 2 et 4, le pourtour de l'ouverture 20 comporte deux bossages 32 diamétralement opposés. La face inférieure de la coque 18 est munie d'une gorge 33 qui entoure l'ouverture 20 et augmente la souplesse de sa paroi. La montre comporte une boîte ronde 34 dont la tranche est munie d'une gorge circulaire 36. Le diamètre extérieur de la boîte 34 est légèrement supérieur à la distance entre les bossages 32, et le diamètre intérieur de la gorge 36 légèrement inférieur. De la sorte, la boîte 34 peu s'engager à cran par sa gorge 36 dans le bossage 32. Ainsi, pour fixer la montre 10, il suffit de la positionner sur le boîtier 12 et d'appuyer. La paroi de la boîte 34 coopère avec les bossages 32 et les écarte grâce à la présence de la gorge 33. Les bossages 32 s'engagent alors dans la gorge 36, bloquant ainsi la montre 10.As can be seen in Figures 2 and 4, the periphery of the opening 20 has two diametrically opposite bosses 32. The underside of the shell 18 is provided with a groove 33 which surrounds the opening 20 and increases the flexibility of its wall. The watch comprises a round box 34, the edge of which is provided with a circular groove 36. The external diameter of the box 34 is slightly greater than the distance between the bosses 32, and the internal diameter of the groove 36 slightly smaller. In this way, the box 34 can engage notch by its groove 36 in the boss 32. Thus, to fix the watch 10, it suffices to position it on the housing 12 and to press. The wall of the box 34 cooperates with the bosses 32 and separates them thanks to the presence of the groove 33. The bosses 32 then engage in the groove 36, thus blocking the watch 10.

L'assemblage des coques 16 et 18 est réalisé par soudage par friction. A cet effet, la coque inférieure 18 présente deux lèvres 42 et 44 (figures 4 et 5) s'étendant sur tout le pourtour du boîtier 12, en direction de la coque 16 et servant d'appui à celle-ci. La coque 16 comporte une lèvre 46, s'étendant également sur tout le pourtour du boîtier 12, et logée dans l'espace compris entre les lèvres 42 et 44. Avant l'assemblage, la lèvre 46 est plus haute que les lèvres 42 et 44. De la sorte, lorsque la coque 16 est placée sur la coque 18, le contact entre les deux coques 16 et 18 n'est réalisé que par la lèvre 46. La coque 16 est ensuite déplacée, latéralement, avec application d'une force perpendiculaire au mouvement, de manière à provoquer l'échauffement de la lèvre 46. L'amplitude du mouvement est de l'ordre de 0,3 mm à 0,9 mm à une fréquence de 100 à 300 Hz, la force appliquée ne dépassant pas 400 kg. Cet échauffement provoque la fusion du plastique des deux coques 16 et 18 respectivement à l'extrémité de la lèvre 46 et dans l'espace compris entre les lèvres 42 et 44. Dès que le mouvement est interrompu, le plastique refroidit et soude les coques 16 et 18, scellant hermétiquement le logement 22.The hulls 16 and 18 are assembled by friction welding. To this end, the lower shell 18 has two lips 42 and 44 (Figures 4 and 5) extending over the entire periphery of the housing 12, in the direction of the shell 16 and serving to support the latter. The shell 16 has a lip 46, also extending over the entire periphery of the housing 12, and housed in the space between the lips 42 and 44. Before assembly, the lip 46 is higher than the lips 42 and 44. In this way, when the shell 16 is placed on the shell 18, the contact between the two shells 16 and 18 is only made by the lip 46. The shell 16 is then moved, laterally, with the application of a force perpendicular to the movement, so as to cause the heating of the lip 46. The amplitude of the movement is of the order of 0.3 mm to 0.9 mm at a frequency of 100 to 300 Hz, the applied force does not not exceeding 400 kg. This heating causes the plastic of the two shells 16 and 18 to melt, respectively at the end of the lip 46 and in the space between the lips 42 and 44. As soon as the movement is interrupted, the plastic cools and welds the shells 16 and 18, hermetically sealing the housing 22.

Le boîtier 12 est incurvé de manière à épouser la forme du bras (figures 3 et 5). De la sorte, le risque d'accrochage est réduit, tout en offrant un autre avantage qui sera précisé ci-après. On peut par ailleurs constater que le bracelet et le grand côté du rectangle opposé au demi-cercle sont sensiblement alignés l'un par rapport à l'autre, ce qui facilite le basculement de ce boîtier du côté où il risque le plus de se produire.The housing 12 is curved so as to follow the shape of the arm (Figures 3 and 5). In this way, the risk of snagging is reduced, while offering another advantage which will be specified below. We can also note that the bracelet and the long side of the rectangle opposite the semicircle are substantially aligned with respect to each other, which facilitates the tilting of this case on the side where it is most likely to occur. .

Ainsi qu'on peut le voir sur les figures 2 et 5, le réflecteur 24 est fixé à la coque supérieure du boîtier par des tenons rivés 47. Il est séparé de la coque inférieure par un espace de l'ordre de 5mm que forme le logement 22. Cet espace est destiné à augmenter le rendement du signal électromagnétique réfléchi par le réflecteur 24. On a en effet constaté que si le réflecteur 24 se trouve trop près du corps, l'intensité du signal réfléchi est considérablement réduite.As can be seen in FIGS. 2 and 5, the reflector 24 is fixed to the upper shell of the housing by riveted studs 47. It is separated from the lower shell by a space of the order of 5mm formed by the housing 22. This space is intended to increase the efficiency of the electromagnetic signal reflected by the reflector 24. It has in fact been found that if the reflector 24 is too close to the body, the intensity of the reflected signal is considerably reduced.

Cette constation étant faite, on pourrait craindre que si, dans une avalanche, l'ensemble restait retourné sur lui-même, présentant ainsi sa face supérieure en appui contre le vêtement, l'intensité du signal renvoyé par le réflecteur 24 soit insuffisante. Or heureusement, il n'en est rien. Cela est dû à la forme légèrement bombée du boîtier, grâce à laquelle, bien que la partie centrale du réflecteur se trouve à une faible distance du corps, les extrémités en sont plus éloignées.This observation being made, it could be feared that if, in an avalanche, the assembly remained turned over on itself, thus presenting its upper face in abutment against the clothing, the intensity of the signal returned by the reflector 24 is insufficient. Fortunately, this is not the case. This is due to the slightly domed shape of the housing, thanks to which, although the central part of the reflector is a short distance from the body, the ends are further away.

Pour fixer le boîtier 12 au bras, le bracelet 14 comprend un ruban 48 tel que représenté à la figure 6. Ce ruban est avantageusement réalisé en un tissage de viscose et d'Elanca (marque déposée). La chaîne du ruban 48 comporte cinq à vingt fils d'élastomère 52, en caoutchouc par exemple, dont le diamètre est compris entre 0,5 et 1 millimètre. Ce type de ruban est vendu par exemple par la maison Wico textile (Suisse). Le ruban 48 a avantageusement une largeur e comprise entre 25 et 50 mm, typiquement 30 mm. Sa longueur est suffisante pour pouvoir entourer le bras du porteur, par dessus un vêtement et atteint 30 à 50 cm. Le tissage est très serré, afin de définir une structure aussi compacte que possible. L'épaisseur du ruban est comprise entre 1 et 2 mm typiquement 1,5 mm.To fix the case 12 to the arm, the bracelet 14 comprises a ribbon 48 as shown in FIG. 6. This ribbon is advantageously made of a weaving of viscose and Elanca (registered trademark). The chain of the ribbon 48 comprises five to twenty threads of elastomer 52, made of rubber for example, the diameter of which is between 0.5 and 1 millimeter. This type of ribbon is sold for example by the house of Wico textile (Switzerland). The tape 48 advantageously has a width e of between 25 and 50 mm, typically 30 mm. Its length is sufficient to be able to surround the arm of the wearer, over a garment and reaches 30 to 50 cm. The weaving is very tight, in order to define a structure as compact as possible. The thickness of the ribbon is between 1 and 2 mm, typically 1.5 mm.

Le coefficient de frottement et la qualité du toucher de la face extérieure du bracelet sont définis par les matériaux tissés.The coefficient of friction and the quality of touch on the outside of the bracelet are defined by the woven materials.

Le mélange de viscose et d'Elanca offre un compromis particulièrement intéressant. Son toucher est agréable, et son coefficient de frottement, sur la neige par exemple, est faible.The blend of viscose and Elanca offers a particularly interesting compromise. Its touch is pleasant, and its coefficient of friction, on snow for example, is low.

La face destinée à être en contact avec le vêtement est avantageusement revêtue de filets de silicone 50 qui augmente considérablement l'adhérence du ruban sur le vêtement. Ces filets ont une largeur de 2 mm et une épaisseur de 1 mm environ. Ils présentent un dessin sinueux de manière à balayer toute la largeur du ruban 48. Ils sont déposés à froid (environ 0°); la polymérisation se fait à température ambiante et crée des liaisons intermoléculaires entre le silicone et les fibres du tissu.The face intended to be in contact with the garment is advantageously coated with silicone threads 50 which considerably increases the adhesion of the tape to the garment. These nets have a width of 2 mm and a thickness of about 1 mm. They have a sinuous design so as to sweep the entire width of the ribbon 48. They are deposited cold (about 0 °); the polymerization takes place at room temperature and creates intermolecular bonds between the silicone and the fibers of the tissue.

Grâce à cette configuration particulière, la face intérieure du ruban présente un fort coefficient de frottement et adhère ainsi parfaitement au vêtement, sans pour autant devoir trop serrer le bracelet. Par contre, la face extérieure offre un minimum de risques d'accrochage. Si toutefois le boîtier était accroché du côté comportant le demi-cercle (le risque d'accrochage sur l'autre côté du boîtier est très faible), il se retournerait sur lui-même en prenant appui sur le grand côté se trouvant dans le prolongement du bracelet, jusqu'à ce que la face supérieure du boîtier soit en contact avec le bras. Dans cette position, l'objet accroché peut s'échapper sans problème, de sorte que le boîtier peut reprendre sa position normale sous l'effet de la force qu'induit le ruban élastique.Thanks to this particular configuration, the inner face of the ribbon has a high coefficient of friction and thus adheres perfectly to the garment, without having to over-tighten the bracelet. On the other hand, the external face offers a minimum risk of snagging. If, however, the box was hung on the side with the semicircle (the risk of catching on the other side of the box is very low), it would turn on itself by resting on the long side located in the extension of the bracelet, until the upper face of the case is in contact with the arm. In this position, the hanging object can escape without problem, so that the housing can return to its normal position under the effect of the force induced by the elastic tape.

Toutefois pour que le basculement du boîtier puisse se faire dans de bonnes conditions, il faut que le ruban ne subisse pas de déformation permanente. Dans un ruban de longueur active L, de largeur e et de limite d'allongement élastique spécifique ΔL/L, il faut que cette dernière remplisse les conditions suivantes:

Figure imgb0001
However, so that the casing can be tilted in good conditions, the strip must not undergo permanent deformation. In a ribbon of active length L, of width e and of specific elastic elongation limit ΔL / L, the latter must meet the following conditions:
Figure imgb0001

Le deuxième terme de l'inégalité définit l'allongement spécifique que subit le côté du ruban le plus déformé lors du retournement. Dans la mesure où cette condition est remplie, l'ensemble ainsi décrit assure une bonne sécurité à son porteur.The second term of the inequality defines the specific elongation which undergoes the side of the most distorted ribbon during the inversion. Insofar as this condition is fulfilled, the assembly thus described ensures good security for its wearer.

La fixation du bracelet au bras peut être faite par exemple au moyen d'une boucle telle que celle vendue par la maison Fixfabriken (Suède) sous la marque déposée Fixlock réf. 327.The bracelet can be attached to the arm for example by means of a buckle such as that sold by Fixfabriken (Sweden) under the registered trademark Fixlock ref. 327.

En variante, la montre 10 pourrait être remplacée par un autre instrument tel qu'un baromètre et/ou un thermomètre par exemple.Alternatively, watch 10 could be replaced by another instrument such as a barometer and / or a thermometer for example.

Dans la solution décrite ci-dessus, le localisateur est un réflecteur passif d'ondes électromagnétiques. Il est bien entendu aussi possible de le remplacer par un localisateur actif à émetteur. In the solution described above, the locator is a passive reflector of electromagnetic waves. It is of course also possible to replace it with an active locator with transmitter.
