Problems solved by technology

In practice, large gaps inevitably occur between the lug and the drive rod on the one hand and the cage and the groove in the bowl on the other, so that the precision of such a device does not meet the highest demands

Embodiment Construction

[0023] The kinematic mechanism according to FIGS. 1 to 3 is used to move a substantially spherical cage 1 relative to a substantially bowl-shaped ring 2 about a first axis A lying in a plane substantially parallel to the top surface of the cage 1 Inside. The gimbal suspension of the cage and the ring is not further shown in the figures, since it is not essential for the description of the invention. The drive means for moving the cage 1 relative to the ring comprise a non-linear drive rod 3 supported mounted in the cage 1 and means for manipulating the drive rod 3 . The drive rod 3 is in the shape of a ring segment, which is rotatable relative to the axis C. Axis C is at 45° relative to axis A. The ring segment is provided with teeth for meshing with the teeth on the driven gear 6 in the drive system 9 (see FIG. 4 ). The drive system 9 includes an electric motor and associated transmission; however, these elements have not been shown for the sake of simplicity. Through the...

Abstract

A movement mechanism comprises a substantially spherical holder and a substantially bowl-shaped ring, which, when inserted into each other, are rotatable relative to each other about at least one first axis (A), which lies in a plane which is substantially parallel with the top face of the holder. Driving means are provided for enabling movement of the holder relative to the ring. These driving means comprise a non-straight driving rod bearing-mounted in the holder and means for activating the driving rod. The driving rod is further connected with a driving part, which is rotatably mounted in a recess in the ring relative to a second axis (B), which second axis (B) lies in a plane equal or parallel to the top face of the ring, and which second axis (B) lies at an angle of approximately 90 DEG to the first axis (A).

Description

technical field [0001] The present invention relates to a kinematic mechanism comprising a generally spherical cage and a generally bowl-shaped ring which, when nested in each other, are rotatable relative to each other about at least a first axis which lies generally parallel to In the plane of the top surface of the cage, a driving device is provided in the kinematic mechanism to enable the cage to move relative to the ring. device. Background technique [0002] Such a kinematic mechanism can be used, for example, to move an object fixedly connected to a holder about one or two axes relative to a fixedly arranged bowl-shaped ring, and can be used, for example, in a rear view mirror of a vehicle, where the mirror surface can be mounted on In the bowl ring, the holder can be mounted in the mirror's housing, which can be fixed to the vehicle. Since the driving device of the mirror can be assembled in the holder, a very compact rear-view mirror adjustment device can be obtai...
