Definitions

  • the invention relates to a watch provided with a device indicating the temperature of the medium in which it is located and more particularly such a watch in which the indicator device is of the thermochromic type and includes means making it possible to give an exact value of the temperature. whether the watch is worn or unworn.
  • German utility models Nos 87 14 620 and 74 20 269 are already known, describing watch thermometers equipped with liquid crystal type temperature indicators.
  • liquid crystal indicators include a plurality of discrete thermochromic sensors, arranged opposite a temperature scale, which reflect light of different color and / or which present a different contrast as a function of the temperature. The temperature can thus be read directly using the graduated scale arranged opposite the sensors.
  • thermometer watch of this kind has the drawback, however, of not taking into account the influence of the thermal contact of the body of the person wearing it, so that the indication of the temperature obtained is imprecise when this watch is worn.
  • thermometers comprising temperature sensors such as thermistors associated with measurement circuits and comprising a switch which can be actuated according to whether the user wishes to measure a temperature while the watch is worn or the watch is unworn.
  • a watch of this type is described, for example, in document JP-A-58117429.
  • the main object of the invention is therefore to remedy the drawbacks of the aforementioned prior art by providing a watch provided with an indicator device making it possible to indicate the exact temperature of the medium in which it is located regardless of whether the watch is worn. or unworn, in a simple and economical way.
  • the invention relates to a watch provided with a temperature indicator device as defined in claim 1 of the patent.
  • This watch makes it possible to simply get rid of the influence of the temperature of the wearer's body and to indicate, in a reliable and correct manner, the temperature of the medium in which it is located, for example the atmospheric temperature, whether the watch is worn or unworn.
  • the temperature of the medium can be easily read by the user whether the watch is worn or not.
  • the invention also relates to a watch provided with a temperature indicator device as defined in claim 2 of the patent.
  • This watch allows the temperature to be displayed fairly while giving the watch an original aesthetic appearance thanks to the simultaneous coloring of at least two sensors.
  • the watch shown in Figures 1 and 2 comprises a box 1 comprising a middle part 2 and a back 4 in one piece, a bezel 6.
  • the box 1 contains a movement 8 surmounted by a dial 10 and two hands 12 and is closed by a crystal 14.
  • the watch further comprises according to the invention, a device for indicating the temperature 16 of a medium in which it is located, whether worn or unworn.
  • the temperature indicator device 16 comprises a first series of temperature sensors 18 of the thermochromic liquid crystal type which each change color at a determined temperature. These sensors 18 are arranged opposite digital indications forming a first temperature scale 20, called the physical temperature scale. Indeed, this physical scale 20 is calibrated so that the indication of the temperature by the sensors 18 is representative of the temperature of the medium in contact with the sensors, that is to say of the temperature of the medium at the level of the sensor.
  • the sensors 18 are formed of discrete sensor elements which are fixed by a film of adhesive 22 in a housing 24 formed in the telescope and are covered with a protective varnish 26. These sensor elements extend at the periphery of the box, each cover an area in the form of a portion of a ring and are each associated with the digital indication of the temperature to which they are sensitive or to which they change color.
  • the temperature indicator device 16 further comprises means for differentiating the temperature indicated by the sensors 18 depending on whether the watch is worn by the user or not worn, this is to say in the latter case distant from the body of the user.
  • the means for differentiating the temperature indicated by the sensors 18 comprise a second temperature scale 28, called the compensated scale and which is arranged, like the first scale 20, opposite the sensors 18.
  • This second scale 28 is however calibrated to indicate a temperature representative of the temperature of the environment when the watch is worn.
  • This second scale may include a sign which distinguishes it from the first scale in order to facilitate reading and to avoid any reading error.
  • the first scale 20 is provided on the bezel 6 and the second scale is provided on the dial 10.
  • the temperature of the medium in contact with the sensors 18 is read respectively in connection with the first scale 20 and the second scale 28 depending on whether the watch is unworn or worn.
  • the temperature indicated by the watch when it is worn is given by the hatched sensor 18 in connection with the second scale 28 and is 20 ° C
  • the temperature indicated when the watch n 'is not carried is given by the same sensor 18 but in connection with the first scale 20 and in this case the temperature indicated is 24 ° C.
  • the differentiation means comprise a second series of sensors 30 of the thermochromic liquid crystal type extending opposite the first scale 20, and such that the indication that they give is representative of the temperature of said medium when the watch is worn.
  • the second series of sensors 30 is arranged concentrically with the first series 18 and the sensor elements 30 of this second series are fixed in the housing 24 formed in the telescope 6 in correspondence with those of the first series 18.
  • each sensor of the first and of the second series is located opposite a single indication of the temperature of the same scale and the reading is facilitated.
  • the sensors 18 respectively 30 which react to the same temperature are offset with respect to each other opposite the scale 20.
  • two sensors, respectively from the first and from the second series are permanently colored and indicate, depending on the series in which they are found, the temperature of the medium when the watch is worn and unworn.
  • the temperature is 16 ° C while it is 20 ° C when the watch is not worn.
  • the bezel 6 is preferably made of a material which has a high thermal conduction such as aluminum or the like and that the middle and the bottom are advantageously made of a thermally insulating material, for example synthetic materials or ceramics.
  • the sensors 18 and 30 can have any other shape and be arranged differently on the watch case.
  • the temperature indicated by the sensors 18 is representative of the temperature of the medium whether the watch is worn or unworn because the influence of the wearer's body temperature is then negligible.
