Abstract
A method for producing a pendulum arrangement of a pendulum laser device includes producing a universal joint of a pendulum of the pendulum arrangement by forming two orthogonal, at least partially micro-structured shafts via plastic injection moulding and positioning at least two bearing shells on the at least partially micro-structured regions of at least one shaft of the universal joint. The method further includes producing an optic carrier of the pendulum of the pendulum arrangement as a single piece with the bearing shells by overmoulding at least two bearing shells surrounding a shaft of the universal joint via plastic injection moulding. The optic carrier is connected to the universal joint such that it is configured to rotate about the one shaft.

A production method for a pendulum arrangement of a pendulum laser device, comprising:
- producing a universal joint of a pendulum of the pendulum arrangement by forming two orthogonal, at least partially microstructured shafts via plastic injection molding;
- placing at least two bearing shells on the at least partially microstructured regions of at least one shaft of the universal joint;
- and
- producing an optics carrier of the pendulum of the pendulum arrangement integrally with the bearing shells by overmolding at least two bearing shells surrounding a shaft of the universal joint via plastic injection molding, and connecting the optics carrier to the universal joint such that it is configured to rotate about the one shaft.
A self-leveling pendulum laser device, comprising:
- at least one housing;
- a pendulum suspension;
- a pendulum that includes an optics carrier attached thereto, the pendulum arranged such that the pendulum is configured to oscillate in the housing via the pendulum suspension;
- and
- at least one laser unit attached to the optics carrier of the pendulum and configured to generate at least one optical marking,
- wherein a universal joint of the pendulum and the optics carrier of the pendulum are configured integrally via plastic injection molding, the optics carrier connected to the universal joint such that the optics carrier is configured to rotate about at least one shaft of the universal joint, and
- wherein the rotatable connection is self-lubricating via a surface capillary structure of one or more of the at least one shaft and the optics carrier.
