Description

[0031] With the intention of better showing the characteristics of the invention a few preferred embodiments of a mechanically driven display according to the invention are described hereinafter, by way of an example without any limiting nature, with reference to the accompanying drawings, wherein:

[0032] FIG. 1 schematically shows a top view of a circular display according to the invention;

[0033] FIG. 2 shows FIG. 1 built into a mechanical precision timepiece;

[0034] FIG. 3 shows FIG. 2 but with the circular display in another position;

[0035] FIG. 4 shows a linear display according to the invention;

[0036] FIG. 5 shows an octagonal display according to the invention;

[0037] FIGS. 6, 7 and 8 show FIG. 5 but now with coloured segments which form digit 1, 2 and 3 respectively.

[0038] FIG. 1 schematically shows a mechanically driven display 1 according to the invention, whereby the balls form one consecutive string 2, which is guided in two concentric tracks a, b by a circular bed 3, only one concentric track of which is visible on the mechanically driven display 1. In this case the string 2 consists of a segment 4 of twenty-four balls with a colour different from the background, represented here as shaded balls and a subsequent segment 5 of twenty-four balls which are not different from the background of the circular bed 3. The mechanical drive is driven by means of a pinion 6 which engages with the balls on the level of the two points 7, 8 where the outer concentric track a continues to the interior concentric track b and each of the two engaged balls 9, 10 make the transition from the outer a to the inner concentric track b or vice versa. The pinion 6 rotates around a shaft 11 which is perpendicular to the plane in which the balls move in the mechanically driven display 1.

[0039] FIG. 2 shows a front view 12 of a mechanical precision timepiece as specified in U.S. Pat. No. 8,743,664 provided with several pointers, but in which a circular mechanically driven display 1 with balls according to the invention is now integrated. Part of a segment 4 of twenty-four balls is visible, the balls of which differ in terms of colour from the background and in which every ball represents a time span of one hour.

[0040] FIG. 3 shows FIG. 2, but now the complete segment 4 of 24 balls is visible by the colour difference with the background, after completing a time span of 24 hours since the appearance of the first ball of the segment 4 on the mechanically driven display. At a glance it is clear that the full cycle of 24 hours is now completed.

[0041] In FIG. 4 the bed 14 is linear and the row of balls forms one consecutive string which is guided through the linear bed 14 in two parallel tracks a, b, being an upward track a and a downward track b, of which in this case only the downward track b is visible on the mechanically driven display.

[0042] In this case there are, for example, twenty-four coloured balls 4 which can fill an entire length of the window through which they are visible on the linear display. In this case the row of balls is driven by two pinions which can rotate clockwise or counter-clockwise simultaneously and make the coloured balls visible in the visible track b, whereby one or more coloured balls become visible on the display, as a unit for the represented parameter.

[0043] FIG. 5 shows yet another variant embodiment 17 of a mechanically driven display according to the invention, whereby the bed 18 forms an octagonal display and the row of balls forms one consecutive string which is guided by one folded track in which seven segments of the track are linear, said segments forming an octagonal figure. In said FIG. 5, the balls 5 all have the colour of the bed 18 and the background of the display and therefore are not visible.

[0044] In FIGS. 6, 7 and 8, the octagonal figure of FIG. 5 is shown but now with two to five segments of six coloured balls 4 which together form the digits 1, 2 and 3 in the octagonal display respectively.

[0045] The operation of the mechanically driven displays 1, 14, 17 according to the invention is very simple and as follows. A consecutive row of balls, which are moved through a bed by means of a mechanical drive, for example, based on one or more rotating pinions is always used, whereby one or more segments of the consecutive row of balls have a colour that deviates from the bed and the display over which they are moved. The number of coloured segments in the row of balls can be limited to one, as applied in a circular or linear display, or can vary from two to seven coloured segments, as applied in an octagonal display.

[0046] The use of one segment of coloured balls allows a visual analogue signal to be shown in a circular or linear display which is proportional to the quantity of a time span or of a physical parameter such as temperature or pressure, to be indicated.

[0047] The use of two to seven segments of coloured balls in one row of balls allows all digits from 0 to 9 to be represented in an octagonal display and consequently also allows digital values of a time span or another physical parameter to be read on a mechanically driven display according to the invention.

[0048] The row of balls is mechanically driven by one or more pinions which are able to rotate clockwise or counter-clockwise and move the desired row of balls in the bed of the octagonal display to show the desired digit. A fitting series of balls can be selected from a carrousel with ten series, one for each digit, to show the desired digit or one long series of balls can be used consisting of the ten desired rows for the ten digits from 0 to 9 one after the other and letting said long series move up with one desired row after a specific time interval, for example, one hour, such that the display shows the number of expired hours up to 9 hours.

[0049] When two displays next to each other are used which together show the desired digit from at least 0 to 24 or 0 to 99, the number of hours can be shown up to 24 hours in two digital digits.

[0050] For the visual analogue signal not only the length of the segment of coloured balls can be used, but a colour gradient can also be used across the segment of coloured balls, whereby the colour may also contain luminescent or phosphorescent components.

[0051] The present invention is by no means limited to the embodiments described as an example and shown in the drawings, but such a mechanically driven display can be realised according to different variants without departing from the scope of the invention, as is defined in the following claims.
