Description

Navigation timer

Technical Field

The utility model relates to a navigation timer, this type's navigation timer includes: table; a support assembly on which the watch is tiltably mounted by means of a gimbal suspension arrangement, the support assembly including the gimbal suspension arrangement; a support which is translatable in a direction substantially perpendicular to the support between a rest position, in which the watch is free to move on the gimbal suspension, and a holding position, in which the watch is fixed in the gimbal suspension, the support comprising a holding mechanism which is able to cooperate with the relative receiving means of the watch to fix the watch in the first position when the support is in the holding position.

Background

This type of timer is particularly disclosed in patent document EP 3318933. The support comprises magnetic means able to cooperate with associated magnetic means of the watch to fix the case. The proposed magnetic device has the dual advantage of allowing the watch to be wound up when necessary and to be fixed in a universal suspension device during any movement, for example during transportation of the timepiece.

The universal suspension device on which the watch is mounted is usually connected to a casing closed by a lid hinged to one of the walls of the casing. Since the walls of the case are generally opaque, when the timepiece is placed on the support and the cover is open, for example on a table, the dial is horizontal and therefore difficult to read if the user is not perpendicular to the watch. Furthermore, it is not easy to access the crown to set the time of the watch.

SUMMERY OF THE UTILITY MODEL

The present invention aims to provide a technically simple and therefore inexpensive solution to overcome the drawbacks of the known nautical timepieces.

To this end, the utility model provides a new navigation timer, it includes: table; a support assembly on which the watch is tiltably mounted by a gimbal suspension arrangement, the support assembly including the gimbal suspension arrangement; a stand movable between a rest position, in which the watch is free to move on the gimbal suspension, and a holding position, in which the watch is fixed in the gimbal suspension, the stand comprising a holding mechanism comprising a first holding means able to cooperate with a first receiving means of an associated watch to fix the watch in the stand when the stand is in the holding position.

Thus, when the stand is in the holding position, the watch can be fixed in the first position or in the second position depending on its position on the gimbal suspension.

The first position of the watch may be a watch winding position, for example a position in which the dial is substantially perpendicular to the vertical axis. The second position may be a position where it is easier to read the dial and/or a position where access to the crown is facilitated to read the time, for example a position where the dial is inclined with respect to the vertical axis by an angle α smaller than 90 °.

The embodiments of the timepiece according to the invention described above may also include-either alone or in all possible combinations-features that will be described in more detail below with reference to the accompanying drawings.

Detailed Description

In the example shown in the accompanying drawings, a nautical timepiece according to the invention comprises: watch 10, the watch 10 comprising a watch case 15; a support assembly 30 on which the watch is tiltably mounted by means of a cardan suspension device, in particular comprising said cardan suspension device; a support 20, which support 20 is movable in translation between a rest position, in which the watch is free to move in the gimbal suspension, and a holding position, in which the watch case 15 is in contact with the support 20. All these elements are housed in a case 1, for example of parallelepiped shape, which case 1 is closed by a lid hinged to one wall of the case 1.

In the example shown, the watch case 15 has the shape of a portion of a sphere and houses a watch movement; the upper part of the case 15 is closed in a conventional sealed manner by a mirror, under which are placed in turn the time indicating hands, the dial 13 and the watch movement and its winding means. The gimbal suspension, known per se, is represented by a suspension ring 14 pivotably mounted on an axis a-a located on the opposite wall of the case 1, the watch 10 itself being pivotably mounted in the suspension ring 14 on an axis B-B extending perpendicularly to the axis a-a.

In the example shown in the drawings, the support assembly 30 comprises:

-a gimbal suspension arrangement for the suspension of the suspension,

-a plate 31 having a plurality of plates,

a lifting mechanism 32, here of the scissor lift type, for translating the support 20 along a holding axis between a rest position (fig. 1), in which the watch is free to move in the cardanic suspension, and a holding position (fig. 3a, 3b), in which the watch is fixed in the cardanic suspension. Here the lifting mechanism is manually actuated by a lever 33 connected to a sector gear which meshes with a sector gear in turn connected to a scissor lifting mechanism, the assembly being arranged such that rotation of the lever 33 causes the scissors of the lifting mechanism to extend or fold, thereby lifting or lowering the support 20. In this example, the rod 33 is mounted on the plate 31, but it is clear that in a variant the rod may be attached to a wall of the housing 1.

The holding axis is here perpendicular to the plate 31. When the watch is placed on a support, such as a table, the plate is horizontal and the holding axis forms a vertical axis.

Here, the watch is arranged inside the case 1, the bottom of the case 1 forming the plate 31 of the support assembly 30 of the watch.

Under normal use conditions, for example when the timepiece is placed on a table, the plate 31 extends in a horizontal plane and the support 20 is movable in translation on a vertical axis perpendicular to the horizontal plane.

The stand 20 comprises a holding mechanism 21, which holding mechanism 21 comprises first holding means 21b, which first holding means 21b are able to cooperate with associated first receiving means 22 of the watch to fix the watch in the first position (fig. 3a) when the stand is in the horizontal holding position. For the timepiece shown in the figures, the first fixed position of the watch is the position in which the dial 13 is substantially perpendicular to the vertical axis. This position of the watch also corresponds to the position of the watch as shown in figure 2, although in figure 2 the watch is not held by the support 20, the support 20 being located at a position remote from the case 15 of the watch 10. In the example shown, the first receiving means 22 and the holding means 21 are mechanical means for both fixing and winding the watch. In particular, the first retaining means are here formed by a plurality of radial ribs positioned side by side on the plate 20a to form the crown, and the first receiving means 22 of the watch are formed by a plurality of radial recesses 22a, the number, shape and arrangement of which are complementary to those of the radial ribs. First receiver 22 is mounted for rotational movement in case 15 and the portion of first receiver 22 extending within the case engages with the winding gear of the watch movement. In the horizontal holding position, the radial rib engages in the radial recess 22a, so that the watch movement can be wound by means of a key (not shown) acting on a winding stem 35, the winding stem 35 meshing with a winding gear train 36, the winding gear train 36 ending in the rotatable plate 20a, and the first holding means 21b being attached to this rotatable plate 20 a.

According to the present invention, the retaining mechanism 21 further comprises second retaining means 21a (fig. 6 and 7), which second retaining means 21a are able to cooperate with the associated second receiving means 12 of the watch when the stand 20 is in the retaining position, to fix the watch in a second retaining position, called the inclined position, which is different from the first retaining position. The second holding position is a position in which dial 13 is inclined by an angle α of less than 90 ° with respect to the vertical axis. In fig. 3b and 4 to 7, the watch is in an inclined second holding position. The angle α is here chosen between 30 ° and 60 ° in order to obtain a comfortable reading position.

The holding means 21 of the stand 20 and the second receiving means 12 of the watch 10 are complementary mechanical means, able to cooperate here to fix the watch in the second inclined position.

In the example shown, the case 15 comprises a pillar extending from the case along an axis P forming an angle α with the dial and forming second receiving means. The stud is here connected to the watch case by means of a lug 12a pressed into a corresponding recess 15a on the outer wall of the watch case 15. The bracket 20 has a recess having a shape complementary to the external shape of the stud of the watch case; the uprights of the watch case and the concave parts of the support form second receiving means 12 of the watch and second retaining means of the support 20, respectively. When the watch case is in the tilted second holding position, the recess and the stud face each other (figures 3b and 6). The column here has a substantially cylindrical shape and a small depth that can be accommodated in a recess of the holding means 21 of the holder 20. As shown in the described example, the retaining means 21 is configured as a crenellated crown, the inner edge of which delimits the space forming the recess (second retaining means) and the rib (first retaining means) of which is able to cooperate in its horizontal position with the first receiving means 22 of the watch.

In another example, not shown, the case part comprises a flat portion (i.e. a partially flat area of the case outer wall), the axis perpendicular to the flat portion forming an angle α with the dial. The holder has a substantially flat contact area, for example formed by the top surface of the radial ribs. The flat contact area of the stand and the flat part of the watch case form the holding mechanism of the stand and the second receiving means of the watch, respectively; the flat portion of the watch case and the flat contact area of the bracket face each other at least partially when the watch case is in the tilted second holding position.

In the example just described, the case comprises a stem extending from the case along a stem axis P forming an angle α with the dial, and in which the cradle has a recess complementary to the shape of the stem of the case, the case stem and the cradle recess forming, respectively, the second receiving means of the watch and the second retaining means of the cradle, the recess and the stem facing each other when the case is in the second position; it is clear, however, that in a variant not shown, the watch case has a recess extending from the watch case along a recess axis making an angle α with the watch disk, and in which the support has a stud complementary to the shape of the case recess, the case recess and the support stud forming, respectively, the second receiving means of the watch and the second retaining means of the support, and the recess and the stud facing each other when the watch case is in the second position.

In a variant not shown, it is also possible to envisage a support which, instead of moving in translation as in the example shown, moves in rotation like a rod which can pivot between a rest position in which the watch is free to move on the cardanic suspension and a holding position in which the watch is fixed in the cardanic suspension, the pivoting support carrying second holding means which can receive second receiving means which in this case are uprights.
