Definitions

  • the present invention relates to a timepiece with analog display of the current time in a given time zone identifiable by the name of a city belonging to said time zone, said timepiece comprising a mechanism for quick time zone change and time correction jumping without risk of deterioration of said mechanism.
  • the present invention overcomes the drawbacks of this art by providing a timepiece that includes a mechanism particularly simple, robust and easy to handle with a clear and well displayed readable.
  • the intermittent link includes in addition to a loop-shaped winding spring, one end of which is secured to the roadway and whose free end extends beyond said toothed sector and remains in support against a pin fixed on the rake in front of the attack tooth, to drive, by rotation of the roadway, said rake in rotation until its leading tooth meshes with the leading tooth of the toothed sector.
  • the timepiece shown in Figure 1 is a wristwatch whose display system includes a 14 minute hand with continuous drive, moving on a dial 1, an hour disc 2 placed under the dial 1 driven step by step every hour and whose hour indications 3 are visible in a large window 4 placed at noon in dial 1, and a locality disc 5. This is also placed under dial 1, bears indications 6 giving the names of cities selected according to their geographic position, and can be operated as required will see further so as to show the name of the desired city in a second window 7 located at six o'clock in dial 1.
  • the timepiece described comprises in the case 8 a movement which can be of any type, for example electronic motor and time base quartz, or mechanical with a spring and a balance-spring time base.
  • the setting the time of the indicating organs is normally carried out by means of a crown 9 mounted at three o'clock, which can have several axial positions depending on the auxiliary functions which it is called upon to perform. We will come back to the function of push-piece 10 located at two o'clock. Crown 9 and pusher 10 ensure alone all the time setting and shift control operations hours.
  • the watch movement comprises a central carriageway 11 which is connected by a gear train 11a to the mechanism so that it performs one revolution per hour around its axis.
  • the time-setting mechanism leading to crown 9 is designed so that the roadway 11 is disconnected from the train during an adjustment maneuver.
  • a second pavement 12 On the pavement 11 is mounted a second pavement 12, called the driving pavement of hours, the upper part of which crosses a central opening 13 of the dial 1 and carries the minute hand 14.
  • the driving surface of the hours 12 is rigidly coupled to the roadway 11. It passes through a tube 15, driven into the board mechanism 17, and comprising a collar 16 for guiding the stars.
  • the mechanism for the rapid control of time differences has a display assembly formed by two stars 20, 24 and two concentric discs 2, 5.
  • a second star 24, called the city star, has the same outside diameter as star 20, freely rotates on it and carries the city disk 5 similarly fixed by pins and screws (not shown) on the barrel of star 24.
  • Disc 2 extends into an annular recess in the disc 5, immediately below the dial 1. Its indications appear in the window 4.
  • each star 20 and 24 are visible at the Figure 2, and shown here partially cut away.
  • Two necklaces 28 and 29 fixed on the board 17 immobilize, under the action of "U" springs 26 and 27, the indicator members 2 and 5.
  • the first of these members 2 is intermittently driven, at the rate of one step per hour per movement.
  • a pivoting rake 30 consisting of a board 31 and a toothing 32 separated by a cutout 33, the assembly being pivoted by a screw 34, while being held by a spring 40 bearing against an eccentric stop 41.
  • the toothing 32 has a greater thickness weaker than the board 31.
  • a retaining nail 37 is provided, driven into the board 17, the head of which is flush with the edge 33a of the toothing 32 on the side of the cutout 33.
  • the toothed sector 32 is delimited by a first tooth 32a called “tooth” attack “and by a last tooth 32e called” escape tooth “, being provided with before the attacking tooth of a winding pin 36, the function of which will be explained further.
  • the board 31 pivots by means of a screw 34 on part thick of the mechanism board 17.
  • the board 31 of the rake 30 is equipped with a pawl 35 pivoting on a nail 21 while being subjected to the action of a spring 35 which keeps pressed against a stop 26. If necessary, the board 31 can also have a retaining spring 27 to prevent the star 20 from jumping a step additional.
  • the driving pavement 12 has a toothed sector 42, delimited by a first tooth 42a called “attack tooth” and a last tooth 42nd called “escape tooth”, between which is a sector free 43 consisting of a notch having no teeth.
  • the toothed sector 42 has 8 teeth angularly offset 30 °. It is obvious that the number of teeth and their pitch may be different insofar as the free sector 43 is maintained.
  • the driving pavement 12 further comprises a loop spring 44, of the type "semi-overturned", one end 45 of which is fixed to the carriageway 12.
  • the free end 46 of the spring 44 extends beyond the toothed sector 42 and rests on a pin 36 of rake 30.
  • the two parts forming the intermittent drive mechanism are arranged in such a way that the axis of rotation 34 of the rake 30 allows the toothing 32 to mesh with the toothed sector 42 of the driving pavement 12, and that the winding pin 36 is beyond the line of action of the toothed sector 42, so as to allow free play of the teeth 32 of the rake 30 in the free sector 43 of the driving pavement 12.
  • the winding spring 44 drives by means of pin 36 the rake 30 in rotation to a position where the attack tooth 42a of the toothed sector 42 engages under the attack tooth 32a of the rake, without the free end 46 of the spring 44 leaving the pin 36.
  • time indication 3 then appears in the window 4.
  • the time indications 3 are marked clockwise and the rotation of the disc, controlled during the return movement of the rake 30, is carried out in the direction counterclockwise. This provision is important. It is the basis of the fast jet lag which we will describe now.
  • the two stars 20 and 24 are superimposed, coaxial and provided with identical teeth which, in the embodiment described, are twelve teeth away.
  • a corrector 38, lever-shaped with a single pivoting branch at 39 on the mechanism board 17 biased by a spring 48, is placed so as to be actuated by the pusher 10 and then simultaneously penetrate into the teeth of stars 20 and 24 to move them forward one step under the action of the necklaces 28 and 29. The direction of this rotation is counterclockwise so that it can be ordered at any time. If the position of the rake 30 is such that the ratchet 35 is partially engaged in the toothing of the 20 hour star, this ratchet is erased by arming the spring 25 then resumes its place.
  • the two indicator members 2 and 5 advance one step counterclockwise which advances the indication by one hour timetable 3 visible in the window 4 and, simultaneously, from a time zone the indication 6 visible in the window 7.
  • disc 5 On its periphery, disc 5 bears the names of twelve cities selected on around the world and located in different time zones.
  • the number of pressures to exert on the pusher 10 is equal to the offset figure schedule to be entered (for example 1 for London, 6 for New York) while in the second case the number of presses corresponds to the difference between 12 and the number jet lag (11 for Cairo, 8 for Karachi, 3 for Sydney, etc.).
  • disc 5 has 12 positions corresponding to the division into 12 of disc 2, while the globe is divided into 24 time zones, we could write on each of these positions two indications of cities located in time zones 12 hours apart on the surface of the globe.
  • this provision is an option, the described embodiment which presents a only indication of city by position allows appropriate selection which simplifies the use of the watch. For example, you can choose the following city names: Paris (or Geneva), London, Sydney, Brasilia, Hong Kong, Bangkok, New York, Dhaka, Karachi, Abu-Dhabi, Kuwait, Athens.
  • the watch can be easily provided with known additional or auxiliary mechanisms, such as needle central seconds, calendar mechanism, etc.
