A movement mechanism comprising a substantially spherical holder and a substantially bowl-shaped ring, which are rotatable relative to each other about a first axis and a second axis enclosing an angle of approximately 90° to the first axis. Driving means are provided for enabling movement of the holder relative to the ring and comprise a first non-straight driving rod bearing-mounted in the holder, as well as means for activating the driving rod and a second non-straight driving rod bearing-mounted in the holder, as well as means for activating the driving rod. The first driving rod and the second driving rod are rotatable about a third and a fourth axis, respectively, which third and fourth axes are mutually parallel and lie in a plane equal or parallel to the top face of the holder and which third and fourth axes are parallel to or coincide with the first axis. |

1. A movement mechanism comprising a substantially spherical holder (1) and a substantially bowl-shaped ring (2), which, when inserted into each other, are rotatable relative to each other about a first axis (A), which lies in a plane which is substantially parallel with the top face of the holder (1), and a second axis (B), which second axis (B) lies in a plane equal or parallel to the top face of the ring (2), and which second axis (B) lies at an angle of approximately 90° to the first axis (A), while driving means are provided for enabling movement of the holder (1) relative to the ring (2), which driving means comprise a first non-straight driving rod (3) bearing-mounted in the holder (1), as well as means (6, 9) for activating the driving rod (3) and a second non-straight driving rod (3′) bearing-mounted in the holder (1), as well as means (6′, 9′) for activating the driving rod, wherein the first driving rod (3) and the second driving rod (3′) are rotatable about a third and a fourth axis, respectively, which third (C) and fourth axes (C′) are mutually parallel and lie in a plane equal or parallel to the top face of the holder (1) and characterized in that the third and fourth axes (C, C′) are parallel to or coincide with the first axis (A). |
