Definitions

  • 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.
  • wristwatches are worn on the wrist, next to the skin.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the hulls 16 and 18 are assembled by friction welding.
  • 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.
  • 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.
  • 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. .
  • 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.
  • 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.
  • the coefficient of friction and the quality of touch on the outside of the bracelet are defined by the woven materials.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • watch 10 could be replaced by another instrument such as a barometer and / or a thermometer for example.
  • the locator is a passive reflector of electromagnetic waves. It is of course also possible to replace it with an active locator with transmitter.
