Abstract
Description
L'invention concerne une montre munie d'un dispositif indicateur de la température du milieu dans lequel elle se trouve et plus particulièrement une telle montre dans laquelle le dispositif indicateur est du type thermochromique et comporte des moyens permettant de donner une valeur exacte de la température que la montre soit portée ou non portée.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.
On connait déjà des modèles d'utilité allemands Nos 87 14 620 et 74 20 269 décrivant des montres-thermomètres équipées d'indicateurs de température du type à cristaux liquides.German utility models Nos 87 14 620 and 74 20 269 are already known, describing watch thermometers equipped with liquid crystal type temperature indicators.
Ces indicateurs à cristaux liquides comprennent une pluralité de capteurs thermochromiques discrets, disposés en regard d'une échelle de températures, qui réfléchissent de la lumière de couleur différente et/ou qui présentent un contraste différent en fonction de la température. La température peut être ainsi lue directement à l'aide de l'échelle graduée ménagée en regard des capteurs.These 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.
Une montre-thermomètre de ce genre présente toutefois l'inconvénient de ne pas prendre en compte l'influence du contact thermique du corps de la personne qui la porte de sorte que l'indication de la température obtenue est imprécise lorsque cette montre est portée.A 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.
En effet, si la température d'une montre non portée varie linéairement en fonction de la température du milieu dans lequel elle se trouve, il en va différemment lorsque cette montre est portée. Dans ce dernier cas, si la température ambiante est basse, les capteurs se trouvent à une température plus élevée que celle-ci car la montre est en contact thermique direct avec le corps, tandis que si la température ambiante est plus élevée que celle du corps, le phénomène s'inverse.Indeed, if the temperature of an unworn watch varies linearly as a function of the temperature of the environment in which it is found, it is different when this watch is worn. In the latter case, if the ambient temperature is low, the sensors are at a higher temperature than this because the watch is in direct thermal contact with the body, while if the ambient temperature is higher than that of the body , the phenomenon is reversed.
Pour pallier cet inconvénient, il existe des montres-thermomètres comportant des capteurs de température tels que des thermistors associés à des circuits de mesure et comportant un commutateur que l'on peut actionner selon que l'utilisateur désire mesurer une température alors que la montre est portée ou que la montre est non portée.To overcome this drawback, there are watch 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.
Toutefois ces montres-thermomètres utilisent des circuits électroniques de compensation compliqués et sont donc d'un prix de revient élevé.However, these watch thermometers use complicated electronic compensation circuits and are therefore of a high cost price.
L'invention a donc pour but principal de remédier aux inconvénients de l'art antérieur susmentionné en fournissant une montre munie d'un dispositif indicateur permettant d'indiquer la température exacte du milieu dans laquelle elle se trouve indépendamment du fait que la montre soit portée ou non portée, et ce de manière simple et économique.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 independently of the fact that the watch is worn. or unworn, in a simple and economical way.
A cet effet l'invention a pour objet une montre munie d'un dispositif indicateur de la température d'un milieu dans lequel se trouve la montre comportant une première série de capteurs de température du type à cristal liquide thermochromique en regard desquels s'étend une première échelle de température, de sorte que l'indication donnée par les capteurs de la première série, en liaison avec ladite première échelle, est représentative de la température du milieu en contact avec lesdits capteurs, caractérisée en ce qu'elle comprend en outre des moyens de différentiation de la température indiquée par lesdits capteurs selon que la montre est portée ou non portée.To this end, the subject of the invention is a watch provided with a device indicating the temperature of a medium in which the watch is located, comprising a first series of temperature sensors of the thermochromic liquid crystal type opposite which extends a first temperature scale, so that the indication given by the sensors of the first series, in connection with said first scale, is representative of the temperature of the medium in contact with said sensors, characterized in that it further comprises means for differentiating the temperature indicated by said sensors depending on whether the watch is worn or unworn.
Grâce à ces caractéristiques, la montre selon l'invention permet de s'affranchir simplement de l'influence de la température du corps du porteur et d'indiquer, de façon fiable et correcte, la température du milieu dans lequel elle se trouve, par exemple la température atmosphérique, que la montre soit portée ou non portée.Thanks to these characteristics, the watch according to the invention makes it possible to simply overcome 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, by example the atmospheric temperature, whether the watch is worn or not worn.
Selon un premier mode de réalisation de la montre selon l'invention, les moyens de différentiation comprennent une deuxième échelle de température disposée en regard desdits capteurs, ladite deuxième échelle étant agencée pour donner, en liaison avec lesdits capteurs, une indication représentative de la température dudit milieu lorsque la montre est portée.According to a first embodiment of the watch according to the invention, the means of differentiation comprise a second temperature scale arranged opposite said sensors, said second scale being arranged to give, in connection with said sensors, an indication representative of the temperature of said medium when the watch is worn.
Ainsi, la température du milieu peut être aisément lue par l'utilisateur que la montre soit portée ou non.Thus, the temperature of the medium can be easily read by the user whether the watch is worn or not.
Selon un deuxième mode de réalisation de la montre selon l'invention, les moyens de différentiation comprennent une deuxième série de capteurs du type à cristal liquide thermochromique disposés en regard de ladite échelle et agencés de manière à donner, en liaison avec ladite première échelle une indication représentative de la température dudit milieu lorsque la montre est portée.According to a second embodiment of the watch according to the invention, the differentiation means comprise a second series of sensors of the thermochromic liquid crystal type arranged opposite said scale and arranged so as to give, in connection with said first scale, a indication representative of the temperature of said medium when the watch is worn.
Ce mode de réalisation permet d'afficher la température de façon juste tout en conférant à la montre, un aspect esthétique original grâce à la coloration simultanée d'au moins deux capteurs.This embodiment makes it possible to display the temperature fairly while giving the watch an original aesthetic appearance thanks to the simultaneous coloring of at least two sensors.
D'autres caractéristiques et avantages de l'invention apparaîtront plus clairement à la lecture de la description qui suit de modes de réalisation de l'invention donnés à titre purement illustratif et non limitatif, cette description étant faite en liaison avec le dessin dans lequel:
- la figure 1 est une vue de dessus d'un premier mode de réalisation d'une montre selon l'invention;
- la figure 2 est une coupe partielle selon la ligne I-I de la montre de la figure 1;
- la figure 3 est une vue de dessus d'un deuxième mode de réalisation d'une montre selon l'invention; et
- la figure 4 est une coupe partielle selon la ligne III-III de la montre de la figure 3.
- Figure 1 is a top view of a first embodiment of a watch according to the invention;
- Figure 2 is a partial section along line II of the watch of Figure 1;
- Figure 3 is a top view of a second embodiment of a watch according to the invention; and
- FIG. 4 is a partial section along line III-III of the watch in FIG. 3.
La montre représentée aux figures 1 et 2 comprend une boîte 1 comprenant une carrure 2 et un fond 4 en une seule pièce, une lunette 6. La boîte 1 contient un mouvement 8 surmonté d'un cadran 10 et de deux aiguilles 12 et est fermée par une glace 14. La montre comprend en outre selon l'invention, un dispositif indicateur de la température 16 d'un milieu dans lequel elle se trouve, qu'elle soit portée ou non portée.The watch shown in FIGS. 1 and 2 comprises a
Le dispositif indicateur de la température 16 comporte une première série de capteurs de température 18 du type à cristal liquide thermochromique qui changent de couleur chacun à une température déterminée. Ces capteurs 18 sont disposés en regard d'indications numériques formant une première échelle de température 20, dite échelle physique de température. En effet, cette échelle physique 20 est étalonnée de sorte que l'indication de la température par les capteurs 18 est représentative de la température du milieu en contact avec les capteurs, c'est-à-dire de la température du milieu au niveau du capteur.The
Les capteurs 18 sont formés d'éléments de capteur discrets qui sont fixés par un film de colle 22 dans un logement 24 ménagé dans la lunette et sont recouverts d'un vernis protecteur 26. Ces éléments de capteurs s'étendent à la périphérie de la boîte, recouvrent chacun une zone ayant la forme d'une portion d'anneau et sont associés chacun à l'indication numérique de la température à laquelle ils sont sensibles ou encore à laquelle ils changent de couleur.The
Selon ce premier mode de réalisation de l'invention, le dispositif indicateur de la température 16 comprend en outre des moyens de différentiation de la température indiquée par les capteurs 18 selon que la montre est portée par l'utilisateur ou non portée, c'est à dire dans ce dernier cas éloignée du corps de l'utilisateur.According to this first embodiment of the invention, the
Selon ce premier mode de réalisation, les moyens de différentiation de la température indiquée par les capteurs 18 comprennent une deuxième échelle de température 28, dite échelle compensée et qui est disposée, comme la première échelle 20, en regard des capteurs 18. Cette deuxième échelle 28 est toutefois étalonnée pour indiquer une température représentative de la température du milieu lorsque la montre est portée.According to this first embodiment, the means for differentiating the temperature indicated by the
Cette deuxième échelle peut comprendre un signe qui la distingue de la première échelle afin de faciliter la lecture et d'éviter toute erreur de lecture.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.
A cet effet on peut envisager de représenter les deux échelles 20 et 28 avec des couleurs différentes ou encore d'apposer à proximité de ces échelles 20, 28 un code ou une inscription adéquat.To this end, it is possible to envisage representing the two
Dans l'exemple décrit, la première échelle 20 est ménagée sur la lunette 6 et la deuxième échelle est ménagée sur le cadran 10.In the example described, the
La lecture de la température du milieu en contact avec les capteurs 18 se fait respectivement en liaison avec la première échelle 20 et la deuxième échelle 28 selon que la montre est non portée ou portée.The temperature of the medium in contact with the
Comme cela ressort de la figure 1, la température indiquée par la montre lorsque celle-ci est portée est donnée par le capteur 18 hachuré en liaison avec la deuxième échelle 28 et est de 20°C, tandis que la température indiquée lorsque la montre n'est pas portée est donnée par le même capteur 18 mais en liaison avec la première échelle 20 et en l'occurrence la température indiquée est de 24°C.As shown in Figure 1, the temperature indicated by the watch when it is worn is given by the hatched
En se référant maintenant aux figures 3 et 4, on voit un deuxième mode de réalisation d'une montre selon l'invention dans lequel les mêmes éléments que ceux représentés aux figures 1 et 2 sont désignés par les mêmes références numériques.Referring now to Figures 3 and 4, we see a second embodiment of a watch according to the invention in which the same elements as those shown in Figures 1 and 2 are designated by the same reference numerals.
A la différence du premier mode de réalisation, les moyens de différentiation comprennent une deuxième série de capteurs 30 du type à cristal liquide thermochromique s'étendant en regard de la première échelle 20, et tels que l'indication qu'ils donnent est représentative de la température dudit milieu lorsque la montre est portée.Unlike the first embodiment, the differentiation means comprise a second series of
De préférence, la deuxième série de capteurs 30 est disposée de façon concentrique à la première série 18 et les éléments de capteurs 30 de cette deuxième série sont fixés dans le logement 24 ménagé dans la lunette 6 en correspondance avec ceux de la première série 18. Ainsi chaque capteur de la première et de la deuxième série se trouve en regard d'une unique indication de la température d'une même échelle et la lecture est facilitée.Preferably, the second series of
Dans l'exemple représenté à la figure 3, les capteurs 18 respectivement 30 qui réagissent à une même température sont décalés les uns par rapport aux autres en regard de l'échelle 20. Ainsi deux capteurs, respectivement de la première et de la deuxième série sont en permanence colorée et indiquent, selon la série dans laquelle ils se trouvent, la température du milieu lorsque la montre est portée et non portée. Ici, lorsque la montre est portée, la température est de 16°C tandis que celle-ci est de 20°C lorsque la montre n'est pas portée.In the example shown in FIG. 3, the
On notera que la lunette 6 est de préférence réalisée en un matériau qui présente une conduction thermique élevée tel que l'aluminium ou analogue et que la carrure et le fond sont avantageusement réalisés en un matériau thermiquement isolant par exemple en matériaux synthétiques ou en céramiques.Note that the
Bien entendu, les capteurs 18 et 30 peuvent avoir toute autre forme et être disposés de manière différente sur la boîte de montre.Of course, the
On notera que dans le cas où la montre est immergée dans un liquide dont la température est très différente de celle du coprs, la température indiquée par les capteurs 18 est représentative de la température du milieu que la montre soit portée ou non portée car l'influence de la température du corps du porteur est alors négligeable.It will be noted that in the case where the watch is immersed in a liquid whose temperature is very different from that of the body, the temperature indicated by the
