Problems solved by technology

The disadvantage of this robust pendulum system is the cumbersome and costly production of the cross joint, which must work with very little friction
[0003] Furthermore, all known pendulum systems have the disadvantage that they are relatively tall and generally require a separate pendulum damper, so that lengthy leveling operations are avoided

Embodiment Construction

[0018] In the figures, identical structural elements and structural elements having the same function are identified with the same reference numerals.

[0019] exist figure 1 The marking and / or leveling device 1 is shown schematically in FIG. The marking and / or leveling device comprises a housing 2 and a pendulum 3 , which is mounted pivotably relative to the housing 2 in all spatial directions relative to the housing 2 . The pendulum 3 is designed as a rigid linkage element and carries, on its lower end in the plane of the drawing, a light source 4 designed as a laser diode for generating a point-shaped or linear laser beam 5 along the cross-section. , with which a point-shaped or linear horizontal laser line can be projected onto the projection plane.

[0020] At the upper end facing the light source 4 in the plane of the drawing, the rigid pendulum 3 has a ball head 6 which, together with the annular bearing receptacle 7 , forms a self-aligning bearing 8 . The bearing re...

Abstract

The invention relates to a marking and / or leveling device (1) comprising a light source (4) disposed on a pendulum (3) that can pivot relative to a housing (2). According to the invention, means are provided for accelerating (9) the pendulum (3) and / or a pendulum bearing (8) in a pulsing manner.

Description

technical field [0001] The invention relates to a marking and / or leveling device according to the preamble of claim 1 . Background technique [0002] Marking and / or leveling devices with pendulum systems of different configurations for vertically or horizontally orienting light sources are disclosed. In a first disclosed embodiment, the pendulum carrying the light source is configured as a wire or rope. The disadvantage of this pendulum system is that it is particularly sensitive to vibrations and is difficult to stabilize or level. In a second disclosed embodiment of the pendulum system, the pendulum system comprises a rigid pendulum which bears on the edge or point of the knife. A disadvantage is the sensitivity of the pendulum system to collisions. In a third disclosed embodiment, the pendulum system comprises a rigid pendulum which is supported in the form of a cross joint (keel joint). A disadvantage of such a robust pendulum system is the complex and cost-intensive...
