Definitions

• the present invention relates to the field of watchmaking. It relates more particularly to a timepiece comprising a representation of a non-rectilinear object, this representation being generally arranged on a dial, so as to be visible by a user.
• the representation is formed in particular of a movable element kinematically connected to a drive mechanism capable of being driven by a power source.
• the present invention aims to propose a new type of animation, particularly original.
• the invention proposes to represent a non-rectilinear object, that is to say to graphically represent a symbol or a real object in two dimensions. A line segment is not considered a representation of such an object. Disclosure of the invention
• the invention relates to a timepiece as mentioned in the first paragraph of the present application, characterized in that said representation is also formed by at least one second movable member.
• the drive mechanism is arranged so that the movable elements move each in synchronism with each other, between a first and a second extreme positions. These movable elements form said representation in a first size and a second size greater than the first, respectively when they are in their first and second extreme positions.
• a schematic representation of a timepiece according to the invention comprises a watch movement, not visible in the drawing, comprising a power source and a control system, for displaying a time information, for example by means of hands 10, moving over a dial, which hides movement.
• the timepiece comprises a representation of a non-rectilinear object.
• the object is a heart 12.
• This core is formed of a first and a second movable element 14a and 14b, kinematically connected to a drive mechanism 16 capable of being driven by the source. energy of the movement.
• the movable elements 14a and 14b are distinct and independent, that is to say they are not not interconnected by a hinge type hinge system. As will be seen below, however, they can be kinematically connected.
• the drive mechanism 16 comprises a cam 17, driven in rotation by the movement.
• the drive mechanism 16 and the representation are arranged on an independent module, that is to say on an independent frame, mounted on a base movement.
• the cam 17 can then be fixed on a mobile base movement whose pivot axis has been extended so as to extend at the module.
• the possible presence of a gear train also makes it possible to arrange the cam 17 in a place chosen by the manufacturer, without being constrained by the position of the axes of the mobiles of the basic movement.
• the cam 17 takes the form of a toothed wheel, provided with an asymmetric type tooth, wolf tooth or saw.
• the cam 17 may have another shape.
• the profile of the teeth may be adapted, but the skilled person may also consider protuberances of any kind.
• the drive mechanism 16 further comprises two latches 18a and 18b, respectively pivoting about axes A and B. To improve the pivoting of these latches 18a and 18b, both in terms of guiding and friction, they may be mounted on ball bearings 19.
• Each of the latches 18a and 18b is mounted integral with one of the movable elements 14a and 14b.
• a pin can be fixed on each of the latches so as to rigidly connect the latch 18a or 18b and the movable member 14a or 14b.
• the moving elements can receive a barrel and be assembled on the latches in the manner of the needles of a timepiece.
• the pins pass through the dial through ad-hoc windows in this one.
• the windows can advantageously be hidden behind the movable elements 14a and 14b, whatever their position.
• the first latch 18a comprises a first probe 20a, held pressed against the cam 17 by a first spring 22a.
• first latch 18a has a second probe 20b which is held against a stop 24a located on the first latch 18a, by a second spring 22b.
• first latch 18a is rotated directly at the discretion of the movements of the cam 17, the second latch 18b it is driven indirectly indirectly via the first latch 18a.
• the movements of the two flip-flops are perfectly synchronized, without differences in the setting of the springs 22a and 22b or at the level of the cooperation between the feelers and the cam 17, disturbing the synchronism of the displacement of the two flip-flops 18a and 18b .
• the synchronization of the movements of the latches 18a and 18b can also be obtained with a support of the two flip-flops directly on the cam 17, although this requires a fine adjustment of the function.
• ruby probes can be made or coated with a material having a low coefficient of friction with the metal of the cam or the rocker.
• the movable elements 14a and 14b therefore move according to rotations defined with reference to the axes A and B, respectively, these axes being advantageously separate. Thanks to the fact that the movable elements 14a and 14b are rigidly connected to the latches 18a and 18b, the first and the second movable elements move each simultaneously and synchronously with respect to one another, between a first and a second extreme positions and vice versa, that is to say according to a retrograde movement. The first extreme position is visible in Figure 1, while the second extreme position is visible in Figure 3, Figure 2 showing an intermediate position.
• the movable elements 14a and 14b form the representation of the non-rectilinear object, that is to say the core 12, according to a first size.
• the movable elements 14a and 14b form the heart 12 in a second size, larger than the first.
• the representation obtained according to the second size is a similarity of a factor k of the representation obtained according to the first size, k being determined by the design and construction of the timepiece.
• the dimensions of the representation advantageously vary in at least two directions.
• the invention does not therefore consist in representing a simple segment of a line of greater or lesser size, such a segment being furthermore not considered as a representation of a non-rectilinear object, within the meaning of the present invention.
• the drive mechanism 16 is arranged, thanks to the shape of the cam 17, to give the illusion of a beating heart.
• the latches 18a and 18b pivot gradually while the first probe 20a slides on an inclined portion of the cam 17, the first latch 18a driving the second latch 18b. Then, the latches 18a and 18b return abruptly to their initial position when the probe 20a falls after the passage of the tip of the tooth.
• the heart 12 progressively moves from its first to the second size and suddenly returns to its first size.
• each element of the heart has a particular shape.
• each end of the element has a concentric portion to the axis of rotation around which the rocker pivots. This is the case even for the central part of the heart.
• the ends of the movable members 14a and 14b are dimensioned and shaped so as to overlap by interlocking.
• the dial is provided with portions 26 having a similar appearance in terms of material and color, that of the movable elements 14a and 14b.
• the portions 26 are hidden by the movable members 14a and 14b when in their first extreme position. When they pass in their second extreme position, the portions 26 are then visible. Thanks to the shape concentric to the axes A and B, respectively, of the ends of the movable elements 14a and 14b, the portions 26 may have the same dimension, that is to say the same width, as the movable elements 14a and 14b and when visible, form with the movable elements 14a and 14, the heart 12 in its second size. In this case, as can be seen in Figure 3, the portions 26 "extend", even if they are in a different plane, the movable elements 14a and 14b.
• the combination of the specific shape of the core 12, a suitable shape of the cam 17, a suitable driving rhythm allow to give the illusion of a beat of heart, as it is sometimes stylized.
• the representation chosen is that of a heart, but other non-rectilinear objects could also be chosen.
• the movable elements can be combined with static elements, permanently visible, to represent the chosen object.
• the elements mobiles are intended to move in rotation about respective distinct axes, at least around a plurality of axes.
• a drive mechanism 16 as proposed above can be adapted in an electromechanical embodiment.
• control system to engage or stop the drive mechanism 16 and the movements of the representation.
• the control system can act on a clutch mechanism, such as those used in the chronograph mechanisms, inserted in the kinematic chain connecting the movement to the cam 17. The disengagement of the system clutch stops the rotation of the cam 17.
• the control system can act directly on the electronic control circuit.
• the control system may be a manual control system, such as a pusher. But we can also provide an automatic control system, as proposed in alarms or alarm clocks. At a programmed time, the control system then automatically engages the drive mechanism 16 and the heart or the chosen representation moves from one size to another. In such an embodiment of the mechanical type, it can then be provided that the drive mechanism is associated with its own power source, possibly located in the module. However, inspired by a great ring, we can also consider taking the energy for the training of the representation in the barrel of the movement. The stopping of the training occurs either after a certain time or when the specific barrel is unloaded. Those skilled in the art will know how to use their general knowledge of striking mechanisms to implement this variant of the invention. For such an embodiment of electronic or electromechanical type, the electronic circuit can be programmed to react to an actuation of a manual control member or to define the duration and the moment at which the representation is moved.
• the moving elements are directly driven by the movements of an oscillating mass, of the type used in the automatic winding mechanisms, the oscillating mass being fixed in rotation or kinematically connected to the cam, for driving the moving elements according to the movements of the wearer of the timepiece.
• a timepiece according to the invention is applicable in a wristwatch. It may also find application in a jewelery-like ornament (Fig. 4), such as a necklace or other pendant, or like a brooch. Although in this application, the mechanism may not give the time and be lacking, in particular, means of displaying a time information, it may nevertheless be legitimately included in the scope of the terms "timepiece" used in the claims, since it includes systems used in the watch industry.
