Problems solved by technology

If motors, forearm supports and brushes for window cleaning can be standardized beforehand, but this is not the case for intermediate transmissions, the final cost reduction is not worthless

Embodiment Construction

[0032] figure 1 Represent automobile rearview mirror 200, the window cleaning device 1 of an ellipse wiping is installed in its bottom, and this window cleaning device has transmission mechanism 30 of the present invention. It should be noted that this refers to a typical practical example for making an elliptical wiping motion, in the sense that the mirror 200 has a rather small height relative to its width, which is not suitable for any circular wiping motion.

[0033] in order to aptly express the figure 1 In the case of an elliptical wiping motion, the window-cleaning surfaces 210, 220 obtained by the two wiping methods respectively appear on the figure 1 See the mirror 200 on. In this regard, it can be observed that the elliptical surface 210 has a size advantage over its circular counterpart 220 . It can also be observed that the range of the window cleaning brush 100 is in the fixed stop position and the opposite position of the fixed stop, and by comparison, the win...

Abstract

The present invention relates to a drive mechanism (30) especially for a window wiping device (1) with an elliptical wiping motion, said device comprising a primary actuating axle (20), a rotary support (40), a fixed toothed wheel (50), at least one central toothed wheel (60), an output toothed wheel (70), and a secondary actuating axle (80), the toothed wheels (50, 60, 70) being engaged with each other and forming a two-stage gear system. The invention is characterised in that the rotary support (40) comprises two supporting elements (41, 42) that respectively carry the two stages of the gear system, and in that the two supporting elements (41, 42) can be arranged in relation to each other following at least two separate angular positions in which the toothed wheels (50, 60, 70) are effectively engaged.

Description

technical field [0001] The present invention relates to a transmission mechanism capable of converting axial rotational motion into elliptical wiping motion, a window cleaning device with such a mechanism, and an automobile with such a window cleaning device. [0002] The invention is particularly preferably used in the field of window cleaning devices for vehicles, but is not restricted thereto. Background technique [0003] If the windshield of today's automobiles is getting bigger and bigger, it is mainly limited by aesthetics and / or design, and the rearview mirror has a tendency to gradually reduce its volume. In any case, today's window cleaning devices that are pressed against such glass surfaces have to adapt to such innovations. [0004] However, conventional window cleaning devices, that is to say wipers with a circular wiping movement, have proven to be particularly unsuitable for windows that are much wider than they are high. The main consideration here is the ...
