Abstract

The invention relates to a clock comprising a clock face with hands and clockwork elements. Said clock face comprises a non-rotationally symmetric surface in the direction of rotation of the hands. The inner ends of the hands are rotatably mounted in a displaceable manner around a pivoting axis which extends in a peripheral manner with respect to the peripheral rotational axis of the hands and in a perpendicular manner with respect to the longitudinal axis of the hands. A control element is provided, enabling the hands to be pivoted in such a way that they can be displaced at an equal distance from the surface of the clock face as they go round. Said novel clock is characterized in that the hands on the inner end thereof or near thereto are rotatably mounted around a rotating axis extending in the longitudinal direction of the hands; the hands are flat in the visible region thereof; and a control element is provided, enabling the hands to be rotated around the rotational axis thereof in such a way that they can be displaced parallel to the clock face surface as they go round.

Dependent claims

A clock having a clock face with at least one hand and having a clock-work mechanism with at least one concentric motion arbor to move the hand around an axis of rotation of the hand, in which the clock face, when viewed in a clock-wise direction, has a surface which is not symmetric to the rotation, in which the at least one hand is pivotably anchored at an inner end which is adjacent to the axis of rotation around a second axis perpendicular to the axis of rotation and perpendicular to a third pivoting axis which runs in the same plane as a longitudinal axis of the hand in such a way that it can pivot, and in which a control is provided with which the hand can be pivoted about the second axis of rotation in such a manner that it moves over the surface of the clock face at an essentially constant distance, wherein

the hand, at or near its inner end which is facing the first axis of rotation, is attached around the third axis of rotation running longitudinally to the hand in such a manner that it can rotate,
the hand is two-dimensional in its visible area, and
an additional control is provided with which the hand can be rotated around the third axis of rotation along its longitudinal orientation such that in its rotation it moves essentially parallel to the surface of the clock face.
