Definitions

  • the invention relates to a Dewar device for mechanical and/or functional components of a watch, in particular adapted to operate under extreme temperatures, the Dewar device comprising at least one connecting element for the arrangement of a case of the watch in its box.
  • An electronic watch conventionally comprises a bracelet and a watch case comprising several electrical or electronic components. It is known in the state of the art that some of these components cannot withstand extreme temperatures, and cease to operate correctly at these temperatures. Typically, LCD liquid crystal displays using light-emitting diodes or quartz tolerate temperatures not exceeding approximately 80°C (degrees Celcius), and not dropping below 0. °C. However, in particular environments such as for example space or lunar missions, the temperatures can frequently reach values of the order of substantially ⁇ 150° C. to +125° C.
  • the invention relates to a Dewar device for mechanical and/or functional components of a watch, said device being provided with a strap and a case comprising an enclosure in which a case of said watch and at least one reversible connecting element fixing said watch case in said enclosure of the case by keeping it away from all the elements of the case defining this enclosure, said at least one reversible connecting element being provided with a body forming a structure comprising at least one recessed area.
  • the Dewar device formed by the case and the watch case the mechanical and/or functional components of the watch are protected from any extreme temperatures between -150 and +125 degrees Celsius that may prevail outside of said device.
  • said at least one connecting element ensuring the fixing of the watch case to the case participates in ensuring very good thermal insulation of the case by preventing any heat loss from this case 6 of the watch, in particular by radiation.
  • such a Dewar device makes it possible to use mechanical and/or functional components in contexts and environments where the temperatures can be extreme, such as for example during space exploration missions such as the exploration of the planet Mars. or the moon. This also makes it possible to ensure the rationalization of costs as well as to maintain a reasonable complexity for the components used in watches requested for such missions.
  • the figure 1 represents an isothermal timepiece device 1 for mechanical and/or functional components 2 of a watch 3 also called Dewar timepiece device or more simply “Dewar device” in the following description.
  • a Dewar device 1 for mechanical and/or functional components 2 of a watch 3 is able to participate in conferring good thermal insulation on mechanical and/or functional components 2 of the watch 3 of which a box 6 must be arranged in this case 4 of the device 1 in order to provide such insulation to these components 2.
  • this Dewar device 1 is in particular formed by the combination of its case 4 and of the case 6 of the watch 3 in order to achieve an insulation suitable thermal for these mechanical and/or functional components 2.
  • the case 6 of the watch 3 is arranged in an enclosure 5 while being kept remote or at a distance from all the elements 10a to 10c of the case 4 defining this said enclosure 5, namely a crystal 10a, an inner peripheral wall 12 of a middle part 10c and a bottom 10b of this case 4. It will be noted that this inner peripheral wall 12 is also that of said enclosure 5.
  • This distance or this distance is configured (e) from at least one connecting element 7 that we describe later, for (or to participate in) reducing or even eliminating any thermal conduction between the inner peripheral wall of the middle part 10c and/or the back 10b and/or the crystal 10a with the case 6 of the watch 3 in particular with an outer face of this case 6.
  • This external face comprises the external surfaces of the crystal, of the middle and of the back of this case 6 of watch 3.
  • a box 6 is included in a watch 3 which can be an electronic watch, for example a quartz watch or even a mechanical watch.
  • the mechanical and/or functional components 2 of the watch 3, mentioned above, include in a non-limiting and non-exhaustive manner: a watch movement, a dial, hands, rings, seals and/or electronic and/or electrical components 2
  • electronic and/or electrical components include, for example, a display device, a processor, a memory, an energy storage component, a motor, an integrated circuit and an electronic oscillator, etc. ..
  • this Dewar device 1 has the same properties and characteristics as a Dewar tube/vase well known in the state of the art. As we have previously mentioned, the properties and characteristics of this Dewar device 1 participate in giving it good thermal insulation with regard to particularly extreme temperatures that may prevail in the external environment in which such a device 1 can be located.
  • this device 1 therefore comprises the case 4 which comprises the middle part 10c on which is mounted a bracelet allowing a user of this device 1 to wear it.
  • This box 4 also includes the glass 10a and the bottom 10b mentioned above.
  • crystal 10a preferably comprises a surface which is substantially greater or strictly greater than crystal 11 of case 6 of watch 3.
  • crystal 10a, middle 10c and bottom 10b of this device 1 together define enclosure 5 of this case 4 which is capable of receiving case 6 of watch 3.
  • These three elements 10a to 10c of the case 4, the middle 10c, the crystal 10a and the back 10b can be separate elements which are joined together to build this enclosure 5.
  • the middle 10c and the back 10b of the case 4 can together form a part in one piece, said one-piece part defining an opening opposite the bottom 10b which is capable of being closed by the crystal 10a and this, in a reversible and sealed manner.
  • middle 10c and crystal 10a of case 4 can together form a one-piece piece, said one-piece piece defining an opening opposite crystal 10a which can be closed by bottom 10b, also reversible and waterproof.
  • the caseband 10c and the back 10b are preferably made in a non-limiting and non-exhaustive manner from a metallic material, from glass or from thermosetting or thermoplastic polymer resins reinforced with carbon or glass fibers or even from ceramic materials. It will be noted that when caseband 10c and back 10b are transparent or semi-transparent, for example being made of glass, peripheral wall 12 of caseband 10c and the inner face of back 10b can be coated with a metallic or similar reflective coating, such as for example a layer of silver.
  • the device 1 may comprise an interferometric filter arranged on an outer face of the case 4, namely on an outer peripheral wall of the middle part 10c and/or of the outer faces of the crystal 10a and of the bottom 10b of this watch case 6 3.
  • This interferometric filter can be a grid or a lattice forming a coating on this outer face of the case 4.
  • This grid or lattice has a mesh whose dimensions are such that they only allow certain predetermined wavelengths of the spectrum to pass electromagnetic, typically the wavelengths of the visible domain. It will be noted that such a filter participates in ensuring blocking of heat losses by radiation, in particular blocking of infrared waves while allowing the dial of the watch to be read by allowing visible wavelengths generally less than approximately 600 nm to pass.
  • this connecting element 7 when the first end of this connecting element 7 is irremovably connected to the inner peripheral wall 12 and/or to the bottom 10b, it is then fixed to the latter two, for example by gluing or else by welding.
  • this connecting element 7 which is intended to be connected to case 6 of watch 3, is preferably so in a removable manner.
  • this second end comprises an attachment zone which is configured to be linked/connected to an attachment zone of the case 6 of the watch 3 instead of the bracelet of this watch 3.
  • this fixing zone of this second end is able to ensure reversible fixing on a bar included in this fastening zone of this watch 3 or to replace this bar.
  • This connecting element 7 is provided with a body forming/comprising a structure 8 comprising at least one recessed area 9.
  • This recessed area 9 is an empty part of the body of this connecting element 7 or else a part which has been the material constituting the rest of the body of this element 7.
  • each recessed zone 9 is a through opening, a blind opening, a cell or even a perforated zone included in the body of this element 7. It is therefore understood that the structure 8 of such a connecting element 7 comprises this said at least one recessed area 9 as well as a non-recessed area of this body.
  • such a structure 8 may comprise a plurality of recessed areas.
  • the recessed areas have similar shapes. It is understood that in other variants, the recessed areas may have different shapes.
  • such a structure 8 comprising several recessed zones can be a lattice structure 8 such as a microlattice structure or a nanolattice structure, or even a lattice structure 8 which can also be called a triangulated system.
  • Such a structure 8 of the connecting element 7 improves the behavior of the case 6 of the watch 3 in the case 4 by presenting a very good mechanical resistance to any stresses that such a connecting element 7 is likely to undergo in the framework of the use of the Dewar device 1 in particular during the application of an acceleration, a deceleration and/or a sudden (e)/violent (e)/sudden change of direction undergone by this device of Dewar 1 for example during a shock. Furthermore, it will be noted that such a structure 8 gives this connecting element 7 a mechanical strength greater than a connecting element of the state of the art which would have a mass substantially similar or strictly similar to the connecting element 7 of the present invention.
  • this structure 8 is capable of reducing the capacity of this connecting element 7 to diffuse heat between the inner peripheral wall 12 and/or the bottom 10b where the first end of this element 7 is fixed and the case 6 of the watch. 3, either reduce or limit thermal conductivity.
  • the reduced section of one or more parts of the non-recessed zone and/or the length of the thermal path(s) defined by this or these parts of the non-recessed zone between the two ends of this element of connection 7 participates (ent) in limiting or even preventing any heat loss from the case 6 of watch 3.

  • these materials may include: steel, titanium, ceramics or polymers.
  • the case 4 preferably comprises two reversible connecting elements 7 fixing the case 6 of the watch 3 on the inner peripheral wall 12 of the middle part 10c of this case 4.
  • These connecting elements 7 hold the case 6 of the watch 3 at a distance from the crystal 10a and the bottom 10b of the case 4 and also from the inner peripheral wall 12 of the middle part 10c which is that of the enclosure 5.
  • these two connecting elements 7 avoid any direct contact between case 6 of watch 3 and crystal 10a, bottom 10b and this inner peripheral wall 12 of middle part 10c.
  • these connecting elements 7 contribute to arranging the case 6 of the watch 3 in this case 4 so that the crystal 11 of this case 6 of the watch 3 is arranged opposite the crystal 10a of the case 4 so that that the information included on the dial and/or the display interface of this watch 3 can be perceived through the transparent crystal 10a of the case 4 by the user carrying the Dewar device 1.
  • such a Dewar device 1 provides the mechanical and/or functional components 2 of the watch 3 with very good thermal insulation with respect to the external environment by reducing or even preventing heat loss by radiation from the components arranged in the watch box 6 for a long time.
  • the temperature outside the device 1 reaches extreme values, typically of the order of ⁇ 125 to +125° C.
  • the temperature inside the enclosure 5 remains substantially equal to the temperature present in case 6 of watch 3 during its arrangement in case 4, typically around 20°C.
  • the temperature present in the case 6 of the watch 3 is a temperature which does not hinder the correct operation of the watch.
  • This temperature is maintained over a period which is 5 to 18 times longer than the period during which such a watch case would be capable of preserving an operating temperature of its components 2 by being located directly in such an environment where such temperatures prevail. in particular extreme (that is to say by being located outside the case of the Dewar device). It is thus conceivable that such a configuration makes it possible to protect the mechanical and/or functional components 2 of the watch 3, as well as to participate in ensuring their operation in an optimal manner under extreme outside temperature conditions.
