1. A haptic device for vibrating a segment of a control stick on command, wherein the haptic device comprises:
- a base;
a mass assembly comprising at least one shaker branch that shakes to vibrate the segment of the control stick, the at least one branch includes (i) a root connected to the base and (ii) a free end, the at least one branch extending from the root towards the free end circumferentially over at least 45 degrees around a central axis, the central axis being configured in a mounted position to coincide with a middle axis along which the segment of the control stick extends, the root of each branch being connected to the base by respective mobility means conferring a degree of freedom on the branch to move in rotation about a pivot axis, the pivot axis being distinct from the central axis;
electrical exciter means configured to generate a force to cause the at least one branch to shake by moving in rotation about the pivot axis from a rest position to an activated position; and
resilient return means tending to maintain each branch in the corresponding rest position, wherein the resilient return means and the mobility means are separate elements.

Abstract
A haptic device comprising a base and at least one shaker branch. Said at least one branch is connected to the base by mobility means conferring a degree of freedom on the branch to move in rotation about a pivot axis relative to the base. An exciter member comprises electrical exciter means configured to cause said at least one branch to shake by moving in rotation about the pivot axis from a rest position to an activated position, and resilient return means tending to maintain each branch in the corresponding rest position.

18. A control assembly comprising:
-
a control stick; and a haptic device for vibrating a segment of the control stick on command, wherein the haptic device is fastened to an exterior of the segment of the control stick and the haptic device includes; a base; a mass assembly including at least one shaker branch that shakes to vibrate the segment of the control stick, the at least one shaker branch includes (i) a root connected to the base and (ii) a free end, the at least one shaker branch extending from the root towards the free end circumferentially around the exterior of the segment of the control stick over at least 45 degrees around a central axis along which the segment of the control stick extends; mobility means connecting the root of the at least one shaker branch to the base and conferring a degree of freedom on the at least one shaker branch to move in rotation about a pivot axis, the pivot axis being distinct from the central axis; electrical exciter means configured to generate a force to cause the at least one shaker branch to shake, by moving in rotation about the pivot axis from a rest position to an activated position, against the exterior of the segment of the control stick to thereby cause the segment of the control stick to vibrate; and resilient return means tending to maintain the at least one shaker branch in a corresponding rest position, wherein the resilient return means and the mobility means are separate elements.

19. A control assembly comprising:
-
a control stick; and a haptic device for vibrating a segment of the control stick on command, wherein the haptic device is fastened to an exterior of the segment of the control stick and the haptic device includes; a base; a mass assembly including at least one shaker branch that shakes to vibrate the segment of the control stick, the at least one shaker branch includes (i) a root connected to the base and (ii) a free end, the at least one shaker branch extending from the root towards the free end circumferentially around the exterior of the segment of the control stick over at least 45 degrees around a central axis along which the segment of the control stick extends; a spring connecting the root of the at least one shaker branch to the base and conferring a degree of freedom on the at least one shaker branch to move in rotation about a pivot axis, the pivot axis being distinct from the central axis; electrical exciter means configured to generate a force to cause the at least one shaker branch to shake, by moving in rotation about the pivot axis from a rest position to an activated position, against the exterior of the segment of the control stick to thereby cause the segment of the control stick to vibrate; and the spring tending to maintain the at least one shaker branch in a corresponding rest position.
