AN ADJUSTMENT DEVICE FOR INDICATING A PITCH ANGLE, CONDUCTORS EQUIPPED THEREWITH, AND PRODUCTION METHOD AND USE

In manually erecting and positioning ladders, it is of great importance to maintain a comparatively narrow range of inclination angles. From experience, it is not only in the private sector but also, for example, in disaster management not always easy for the persons handling the ladder to achieve the advantageously safe inclination angle range. The present invention relates to an inclination measuring device which has two externally visually accessible reference chambers each with a reference ball displaceable therein by gravitational force for identifying at least one target inclination angle range, wherein the inclination measuring device is configured to be fastened to a ladder, in particular to a rail of a ladder, by means of a bonding auxiliary material or by form-fit or force-fit, or to be provided in an integral configuration with the ladder, in particular with the rail, in particular in each case in an orientation orthogonal or parallel to the (correspondingly selected for the arrangement) surface of the ladder. In this way, the manual handling of ladders in particular is simplified and made safer. Furthermore, the invention also relates to a correspondingly equipped ladder and a manufacturing method for such an inclination measuring device.
