[0006] Dans une forme d’exécution, les éléments de décoration se déplacent angulairement chacun autour d’un axe déporté par rapport à un axe central du châssis annulaire.

[0007] Selon cette même forme d’exécution, une bague fixe, coaxiale au châssis, comporte une denture externe qui engrène avec au moins un mobile denté disposé autour de ladite bague.

[0008] Toujours selon cette même forme d’exécution, les mobiles dentés sont régulièrement répartis autour de la bague fixe, chaque mobile denté portant sur son axe de rotation un élément de décoration.

[0009] Dans une autre forme d’exécution, les éléments de décoration se déplacent angulairement autour d’un seul et même axe centré par rapport au centre du châssis annulaire.

[0010] Selon cette même autre forme d’exécution, l’organe rotatif constitue un premier élément de décoration.

Still according to this same other embodiment, the decoration elements are stacked coaxially one on top of the other, the first decorative element being disposed at the bottom of the stack and having the largest outside diameter. A second decorative element is arranged on the first decorative element and a third decorative element is arranged on the second decorative element. Each decorative element has an outside diameter smaller than the outside diameter of the decorative element on which it is placed.

[0012] According to this other embodiment, the rotary member comprises an internal toothing. The rotary member engages with a gear set arranged to cooperate with the other decoration elements. The gear set is arranged to drive the decoration elements in opposite directions of rotation.

In one embodiment, the device comprises means operable to block the angular displacement of the weighted ring or of the annular sector.

BRIEF DESCRIPTION OF THE DRAWINGS The characteristics of the invention will appear more clearly on reading the description of several embodiments given solely by way of example, and in no way limitative, with reference to the schematic figures, in which:

FIG. 1 shows a perspective view of a decoration device illustrating a camellia;

FIG. 2 shows an exploded view of FIG. 1;

FIG. 3 shows a top view of a decorative device illustrating butterflies;

FIG. 4 shows a partial perspective view of the decoration device of FIG. 3; And FIG. 5 shows an exploded view of FIG. 4.

[0015] As illustrated in FIG. 1, a movable and handy decorative device comprises an annular frame 1. Three decoration elements 2A, 2B, 2C are stacked coaxially one above the other above the annular frame 1. Each decorative element 2A, 2B, 2C is mounted to rotate about a rotation axis 3A to deploy one Effect during the angular displacement of the decoration elements 2A, 2B, 2C, about their axis of rotation 3A. Each decorative element 2A, 2B, 2C has the shape of a star-shaped annular element representing a leaf and petals. A first sheet 2A, of larger outer diameter, has seven petals and is disposed at the bottom of the stack. A second sheet 6 of six petals is disposed on the first sheet 2A and a third sheet 2C is disposed on the second sheet 2B. Each sheet 2B, 2C has an outside diameter smaller than the outer diameter of the sheet on which it is disposed.

The angular displacement of the annular sector 6 (FIG 2) causes the decoration element to rotate about an axis in order to carry out an animation.

[0017] As illustrated in FIG. 2, the movable and handy decorative device comprises an annular frame 1, a set of three decorative elements 2A, 2B, 2C, in the form of sheets. The three sheets 2A, 2B, 2C are disposed above the annular frame 1, a stopper 13 being disposed above the stack, in particular to hold the sheets 2A, 2B, 2C in position. Each sheet 2A, 2B, 2C is mounted to rotate about an axis of rotation 3A. In this example, the axis of rotation 3A is a barrel in the form of a hollow cylinder in which elements constituting a timer of a clock movement 14 can be integrated. The movement 14 is a quartz movement fixed at the bottom to the frame 1 by means of screws and a nesting circle 15.

The annular frame 1 carries the first sheet 2A which is mounted on a ball bearing 5 fixed to the chassis 1 by means of screws. The first sheet 2A is associated with an annular sector 6 arranged so as to produce an unbalance causing an angular displacement of the first sheet 2A during each imbalance of the annular sector 6. The ball bearing is fixed to the frame with the aid of screw. In the same way, the annular sector 6 is fixed to the first sheet 2A by means of screws.

The first sheet 2A is kinematically connected to the second and third sheets 2B, 2C so as to cause them to move angularly about their axes of rotation 3A during each imbalance of the annular sector 6.

In this first embodiment, the first sheet 2A also acts as a rotary member 4 which has an internal toothing 9 for meshing with a gear set 11, 12 arranged to cooperate with the second and third sheets 2B, 2C . The gear set 11, 12 is disposed in the annular frame 1. In this example, the gear set 11, 12 is composed of a pinion 11 and a wheel 12. The rotation of the first sheet 2A causes , By its internal toothing 9, the pinion 11 which cooperates with the wheel 12 to drive the second sheet 2B. The pinion 11 also cooperates with another wheel (not visible) which drives the third sheet 2C. The first sheet 2A rotates in the same direction of rotation as the third sheet 2C. The second sheet 2B rotates in a direction opposite to the first and third sheets 2A, 2C.

[0021] As illustrated in FIG. 3, the movable and handy decorative device represents an animation of six 2D butterflies disposed in a ring-shaped frame 1. The six 2D butterflies are disposed above the annular frame 1, each butterfly 2D being rotatably mounted about a rotation axis 3A disposed at the center of the annular frame 1 for deploying a dynamic decorative effect during the angular displacement of the six butterflies 2D about their axis of rotation 3B.

[0022] As illustrated in FIG. 4, once the 2D butterflies and a dial have been removed, the annular frame 1 carries a rotary member 4 mounted on a ball bearing and associated with an annular sector 6 arranged to produce an unbalance causing an angular displacement of the rotary member 4 during each imbalance of the annular sector 6.

The rotary member 4 is connected kinematically to the assembly of the butterflies in order to cause them to move angularly about their axes of rotation during each imbalance of the annular sector 6.

The butterflies move angularly each about an offset axis 3B with respect to a central axis 3A of the annular frame 1. A fixed ring 7, coaxial with the chassis 1, comprises an external toothing 10 which meshes with six toothed wheels 8 Arranged around said ring 7. The toothed wheels 8 are regularly distributed around the fixed ring 7, each toothed wheel 8 bearing on its axis of rotation 3B a decoration element 2D.
