Definitions
- the object of the present invention is to provide a large format date display mechanism for all watch movements, in particular watches and clocks, allowing easy reading of the date, the construction of which is simple since it requires and combines a reduced number of parts and mobiles.
- This invention also aims to reduce the volume (in particular by reducing the height) of the above-described mechanism and make it, once the preassembled mobiles easily adaptable to all existing watch movements comprising a traditional date indication by crown, since this mechanism can be driven by the date crown of the movement of the watch concerned which will be modified accordingly.
- the subject of this invention is a large format date display mechanism for all movements of watches and clocks making it possible to achieve the above-described aim and comprising the characteristics defined in claim 1.
- the appended drawing schematically illustrates in an exploded view the large format date display mechanism which has three mobiles.
- the mechanism can be illustrated by the following five plans:
- Plan C plate surrounding the crown (s) of plane B intended to be fixed to the watch movement
- - Plan D system comprising three vertical axial screws respectively supporting a toothed star (4 branches) fixed to a notched disc on the surface of which are written four digits from 0 to 3, a jumper and a locking spring.
- the mechanism firstly comprises a programmed crown 1 intended either to replace the original crown of the date 2, or to be fixed on this crown of the original date 2.
- This programmed crown 1 that is 1/2, has a toothing 4 composed of four teeth.
- the programmed crown 1 includes, like the usual date crowns, the inscription of a series 3 of 31 digits arranged tangentially, ie the digits 1, 1, 2,3,4,5,6,7,8,9 , 0, 1, 2,3,4,5,6,7,8,9,0, 1, 2,3,4,5,6,7,8,9,0, uniformly distributed which are intended to indicate the date units.
- the programmed crown 1, that is 1/2 does not include a figure representing the tens A kinematic chain drives this crown 1, or 1/2, at a rate of one step per day from the hour wheel of the watch movement (plane A) to complete a rotation in 31 days.
- This training is discontinuous and the step takes place around midnight each day.
- This programmed crown 1 that is 1/2, could also be driven by a stepping motor (quartz movement) and a gear driven by this motor, motor controlled by an electronic movement timepiece.
- the plane C consists of a plate 5 surrounding the programmed crown and intended to be fixed to the movement of the watch (plane A).
- This plate 5 includes a light in an arc 6 allowing the passage of the date crown (1 or combination 1, 2 of the programmed crown), plate which is fixed to the watch movement by screws 7.
- This mechanism includes a dozen mobile.
- the tens mobile is made up of a star 8 with four branches or teeth, a notched disc displaying the tens 9 having on its upper surface numbers from 0 to 3 arranged tangentially and uniformly distributed.
- a jumper 1 1 is fixed to the plate 5 by an axial screw 12 and comes into contact with the branches of the star 8 located at the same level to keep the angular parts locked between two successive actuations.
- a locking spring 1 3 is fixed to the plate 5 by an axial screw 14 and maintains the jumper between two successive actuations.
- the mechanism is provided with a dial 1 5 pierced with a large window 1 6 with 2 windows of a dimension, in principle a minimum of 2 ⁇ 4 mm, dial which covers the entire mechanism and is fixed using feet. 1 7 (4 in number) on deck 5.
- the tens disc 9 advances by one step every ten days so that the number corresponding to the tens of the date appears in the window 1 6 of the dial 1 5 next to the numbers of the units 3 arranged on the programmed crown 1, that is 1/2.
- the tens disc rotates completely in one month.
- This mechanism makes it possible to arrange the large aperture 1 6 of the dial 1 5 at numerous points on the dial surface 1 5 provided that the two display discs are fixed symmetrically on each side of an axis so that the tens and the units meet and are displayed respectively to the left and to the right of the tangent point.
- topological implantation of the mechanism, object of this invention allows a variation of arrangement of the window going on an open angle between 1 1 H and 1 H on the top of the dial and on an open angle between 5H and 7H on the bottom of the dial.
- the mechanism has a very limited number of parts and only three mobiles (two mobiles on the D plane and one mobile on the B plane). It can be fully assembled and pre-shown on the plate 5 with the exception of the programmed crown 1 which is placed on the movement.
- the plate is then equipped with the dial which will allow the display of the large date calendar.
- the window 16 is twice as large as that of a conventional window.
- the volume of the mechanism is very low, which allows adaptation to all currently existing movements providing for the display of the date.
- this invention aims to manufacture and produce a movement of watches or clocks provided with a large format date display mechanism as described above.
