Definitions

  • the present invention relates to the field of wrist watches and more particularly to wrist watches of the type having an analogical display.
  • Modern wrist watches are ever more often provided, in addition to the base functions (i.e. indication of the date and time), with a series of accessory functions of various types which often still pertain to the measurement of time, such as chronograph functions, the indication of the time in different time zones and the reading of lunar phases, but sometimes also relate to entirely different fields of use which require the watch to be equipped with specific additional instruments.
  • base functions i.e. indication of the date and time
  • accessory functions of various types which often still pertain to the measurement of time, such as chronograph functions, the indication of the time in different time zones and the reading of lunar phases, but sometimes also relate to entirely different fields of use which require the watch to be equipped with specific additional instruments.
  • watches with compasses, altimeters and/or depth gauges, pulsimeters and still other functions.
  • the monitor in normal conditions indicates the basic information or, in other words, the hour, minute and sometimes second.
  • the time is substituted by one or more displays in which the information provided by the accessory functions is shown.
  • the multiple functions of the watch do not compromise the wearer's ability to easily read the information provided, even though there is the problem that when the monitor has been set to a certain position, only some of the information can be read, and it is not possible to see all the information together.
  • the external appearance of this type of watch is often considered rather unattractive and, in any case, is not comparable to that of an analogical watch.
  • the indications provided by the additional functions can be made accessible both in an analogical form, with the use of additional hands and special reference points on the watch dial, and in a digital form by means of windows opening on the watch dial itself.
  • considerable problems are created in the ease with which the watch can be read, since the accumulation on the watch dial of hands, writing, signs and windows of various types can make it difficult to read each single piece of information.
  • the base information provided by the watch i.e. the time
  • becomes almost illegible when, on the contrary, it should be immediately legible even with a distracted glance and in conditions of reduced or difficult visibility. It is important to remember that such conditions are very frequent in the use of this category of watch since it is worn mainly during athletic activity.
  • the object of the present invention is to provide an analogical watch wherein the presence of a certain number of accessory functions does not compromise the legibility of the watch, thus making it possible to easily read the information provided by each function.
  • analogical wrist watch which comprises: a watchcase; a movement inside said case; a hand-supporting stem extending from said movement; a lower dial situated below the hands; a mobile diaphragm made of thin plate elements having substantially the shape of sectors of an annulus and being mobile between a position of reciprocal engagement, to accomplish a closed position of the diaphragm, and one of disengagement, to accomplish an open position of the diahragm and transmission means, associated with the thin plate elements, which can be operated from the outside of said watchcase to move said elements between said engaged and disengaged positions.
  • the novel feature of the watch consists in the fact that the diaphragm is located between the hands and the lower dial whereby, in the closed position of the diaphragm, the thin plate elements are completely superimposed on the lower dial, and in the open position of the diaphragm, the dial is uncovered and thus legible.
  • an upper dial is provided having a substantially annular shape, placed above said diaphragm coaxially to the lower dial.
  • the watch according to the invention comprises a substantially circular watchcase 1 having a back la which is sealing screwed to it and is therefore movable.
  • a movement 2 is provided of a known mechanical or electronic type, schematically illustrated in figure 1.
  • a rotatable pin 3 radially extends for the conventional operations of setting, and can be manually operated from the outside of watchcase 1 by acting on a crown 4 coaxially placed at its free end.
  • a hand-supporting stem 5 also extends centrally from movement 2, and supports two groups of hands lying on two parallel planes orthogonal to stem 5 and, more specifically, a group 6a, which extends from stem 5 in proximity to its base, and a group 6b, which extends from stem 5 in correspondence with its free end.
  • a diaphragm, generally indicated at 8, is located above dial 7 and comprises a fixing ring nut 9, integrally mounted inside watchcase 1 and having a substantially annular shape, on which a plurality of angularly equidistant holes 10 are formed along a circular trace.
  • a rotatable pin 11a is engaged extending from one end of a corresponding thin plate 11.
  • Each thin plate 11 is situated parallel to lower dial 7 and has substantially the shape of a sector of an annulus, as shown in figure 5, with an average radius substantially equal to the average radius of ring nut 9.
  • a semicircular cutting 13 On the side of each thin plate 11a having the smaller radius, is formed in a central position.
  • a rotatable ring nut 14 which is also substantially annular and visible in figure 4, is placed immediately above fixed ring nut 9 and thin plates 11 and is bound to watchcase 1 by a side device, not shown in the figures, which allows for its rotation around its own axis.
  • Ring nut 14 has a plurality of substantially radial grooves 15, in a number corresponding to that of thin plates 11.
  • thin plates 11 In order to make the movement of thin plates 11 possible, they are mounted in such a way that they can be partially superimposed on one another, leaving about half of each one free. From this free end, pins 12 extend.
  • Rotatable ring nut 14 has, on its upper side, a circular toothed track 21.
  • a rotatable pin 16 radially extends from a side hole 1b of watchcase 1, so that one of its ends is outside watchcase 1 and the other is inside.
  • a pinion 17 is mounted for engagement with the toothed track of ring nut 14, whereas the external end has control crown 18.
  • a graduated dial 19 which hereinafter will be referred to simply as upper dial, is fixed integrally to watchcase 1 and has a substantially annular shape so as to make lower dial 7 legible when thin plates 11 are in a disengaged position.
  • the watchcase is closed with a transparent cover 20 of a conventional type.
  • the watch according to the invention has the feature that it maximally facilitates the reading of the information provided by the instrumentation which is equipped with.
  • thin plates 11 when thin plates 11 are in the position of reciprocal engagement, their superimposition carries out a complete closure of diaphragm 8, making the area below, and more specifically lower dial 7 and hands 6a, inaccessible to the eye.
  • the union of cuttings 13 of each thin plate generates a circular seat for stem 5, and only the indications provided by hands 6b and upper dial 19 are legible.
  • a lever is provided which extends from the ring nut itself and engages slidingly in a slot formed on the watchcase and which can be operated from the outside by means of a tangential action exerted directly on its free end or on a ring nut connected to it and mounted on watchcase 1 in a rotatable manner.
