Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-display wristwatch, a first time display on a watch face and a second display at the periphery of the watch face, the second display indicating any information given , The wristwatch comprising a movement which causes the first display.

[0002] Dual-display timepieces already exist. For example, patent CH698748 discloses a wristwatch comprising a display for indicating the time and two plates located between the horns and the dial displaying the month and day of the week.

[0003] Flap displays are known in the prior art, in particular for their use in airports, stations, or clocks. Patent FR 1 269 457 proposes a display consisting of rollers with movable flaps containing any number of flaps. These models show information in a vertical orientation and, by gravity, lower flaps are held down and remain in position. Upper flaps can rest against pawls, the weight of the pawl providing sufficient force to prevent rotation under the effect of its own weight. Such a display can not be incorporated in a wristwatch.

SUMMARY OF THE INVENTION The object of the present invention is to propose a double-display wristwatch in which the first display indicates the time on a dial and a new second display indicates information on the periphery of the dial.

According to the invention, a double-display wristwatch comprises a first time display on a watch face and a second display at the periphery of the watch face, the second display indicating any information given . The wristwatch also includes a movement which causes the first display. The second display comprises at least one set of two wheels arranged in parallel and spaced from each other, each set of two wheels being mounted for rotation about an axis transverse to the center of the watch face. A series of flaps is pivotally mounted between the or each set of two wheels in the direction of their periphery about an axis parallel to the axis of rotation of the or each set of two wheels, So that when the two wheels of one set are rotated relative to a given angular position, two flaps pivotally adjacent one another are placed one in the extension of the other to display information . Means are provided for driving the or each set of two wheels in rotation synchronously with the first display and a system is provided for holding the flaps in place and which is arranged, regardless of the orientation of the watch -bracelet, to hold the adjacent flaps in a display position.

[0006] Preferably, the two sets of two wheels may be arranged side by side along a common axis. When the wristwatch has two sets of two wheels, the flaps of a set of wheels can provide a digital display, for example showing numbers ranging from 0 to 12, 0 to 24 or 0 to 31, and the flaps of The other set of wheels can provide an alphabetical display, showing for example a plurality of place names, or a plurality of names of the months of the year.

[0007] The two wheels of the or each wheel set may comprise at their periphery a series of through holes, each flap comprising on its opposite sides projecting pins which pivotally engage in holes Crossings of the wheels facing each other. In this case, at least one axis of each flap may comprise a profile such as a flat and the mechanism further comprises a spring which cooperates with said profile of a flap axis in order to keep the flap in a given angular position .

Preferably, the periphery of the wheels may comprise a series of indentations between the position of the through holes and a flip-flop cooperates with the indentations so that the wheels can rotate in only one direction.

[0009] A gear train can kinematically connect the movement of the wristwatch to at least one set of two wheels. The gear train may comprise an hour wheel which rotates once per hour, the gear train driving a set of two wheels by one rotation per 24 hours.

A manually operated button may be provided for rotating at least one set of two wheels in an increment, for example one hour or one day.

In a particular embodiment, a first set of wheels and a second set of wheels can be connected so that when the first set of wheels is driven in rotation, it drives the second set of wheels in rotation while The second set of wheels can be rotated independently of the first set of wheels.

The wristwatch illustrated has a double display, a first time display 32 on a dial 36 of the watch and a second display 33 at the periphery of the dial 36 of the watch, the second display 33 indicating the time zone Time by the city name and the time zone. The wristwatch includes a movement 1 which drives the first display 32. As shown, the second display 33 comprises two sets of two wheels 5-5 ', 6-6' arranged in parallel and spaced apart from each other, each set Of two wheels 5-5 ', 6-6' being mounted to rotate about an axis transverse to the center of the dial 36 of the watch. A series of flaps 3, 3 'is pivotally mounted between each set of two wheels 5-5', 6-6 '

In this example, the two sets of two wheels 5-5 ', 6-6' are arranged side by side along a common axis. The flaps 3 of a set of wheels 6-6 'provide a numerical display corresponding to one hour between zero and twenty-four and the flaps 3' of the other set of wheels 5-5 'provide a corresponding alphabetical display In the name of places (London, New York, ...). Each set of wheels carries a set of twenty-four flaps 3, 3 '.

A transmission system, including the gear train 10-14, drives a cam 17 (FIG 3) which activates a rocker 16, activating an incremental jump of the wheel assembly 6-6 'by the rotation of one Star wheel 9 held by a jumper spring 15. The gear train 10 rotates, so that the wheel rotates once in twenty-four hours in fifteen steps. A wheel 6 'has an indexing pin 21 (FIG 4) cooperating with the star wheel 9, held by a jumper spring 15, so that the rocker 16 activates the jump of the wheel assembly 6-6'. Consequently, the wheel assembly 6-6 'also rotates once in twenty-four hours in fifteen steps.

The two wheels 5-5 ', 6-6' of each set comprise in the direction of their periphery a series of twenty-four through holes 20, each flap 3 having on its opposite sides projecting pins 24 Which engage pivotally in opposite through holes 20 of the facing wheels 5, 5 ', 6, 6'. An axis of each flap 3 comprises a plate 29 (FIG. 12). The mechanism further comprises a jumper spring 7 (FIG 3) which cooperates with said plate 29 of a flap axis to keep the flap 3 in a given angular position, whatever the orientation of the wristwatch, c That is to say, in contrast to the known flap displays for clocks which only operate when they are placed vertically. Each flap has four projecting pins 24 arranged in pairs.

The flaps 3, fixed to the wheels 5, 5 ', 6, 6' by the pawl 19 (FIG 4), cooperate with a spring 23 (FIG 8), so as to cause the flap 3 to rotate one hundred Eighty degrees when the wheels 5, 5 ', 6, 6' rotate by fifteen degrees. This rotation of one hundred and eighty degrees relates only to these flaps 3 which are situated at an angle corresponding to the display position.

The pawl 19 comprises an indexing slot 34 in which the flap 3 abuts against a flat 25. In the extension of the pivot axes 26, a round part with two projections 27 cooperates with a spring 23 to pivot the flap 3 180 degrees.
