DE3405143A1 - Device for cleaning reflectors on reflector supports - Google Patents

Abstract

The automatic cleaning of reflectors on road reflector posts takes place by the actuation of a vertically mounted pivotable plate which is arranged on the reflector post and guides a cleaning member similar to a windscreen wiper over the reflector. The actuation of the plate takes place by gusts of wind such as arise as a result of air displacements at the roadside when fast or large-volume motor vehicles pass the road reflector posts.

on reflector supports
Heinz Schwartz, engineer (grad), 808 Grobenzell

The invention relates to a device for cleaning reflectors, especially the traffic control and the Limit display are used, with the reflector support being assigned an element that is sensitive to wind pressure. Its application by wind, as it is caused by passing motor vehicles on the reflector support, changes the geometric shape of the element and thereby leads a cleaning organ over the reflector. Here the reflector support is a road marker, as described in the "Instructions for

Order and execution of vertical guidance systems on Pundesfernstraßen "(HLB) is described.

Especially the reflective effect of the rectangular reflector, which is on attached to the road delineator on the right-hand side of the road is intended for road users during the day and at night and in all weathers, to be perceptible from a distance, to have the traffic area clearly visible - especially this one The reflector (rectangular reflector) is very susceptible to dirt from passing vehicles.

The roadside delineator is known to use long-fiber rotary brushes and water as a whole can be machine washed. This cleaning process is expensive compared to the purchase price of a delineator post. the Cleaning cannot be carried out very often in the year, as washing equipment and staff are only available to a limited extent.

ka * Hn / there are also * latent applications available, according to which dirty rectangular reflectors are replaced by mechanical devices on the delineator post.

In the case of mechanical cleaning of the delineator posts, it is very often the case that a delineator post that has just been cleaned is soiled again for a short time. This fact results in the necessity of constant cleaning of the rectangular reflectors.

The invention is based on the object, the rectangular reflector of a delineator post without human or machine Help to clean up on an ongoing basis. JDaau is supposed to displace that leads to gusts of wind in the direction of the roadside, and occurs through passing, fast or large-scale motor vehicles, be used.

The object is achieved according to the invention in that the delineator post is connected to an element sensitive to wind pressure is that when the gusts of wind act on it Motor vehicles, changes in its geometric shape and the cleaning element is similar to a disk ■ wiper leads over the reflector.

The horizontal movement of the cleaning organ on the visual surface of the reflector is achieved by a triangular joint system, which consists of two movable joint parts, between which one or more coil springs or elastic cables sit, which the joint system after the cleaning process pull it back to its original position. The preload of the springs or cables must be set in this way be that the pivoted hat only swings around the axis when fast or large-scale motor vehicles

the delineator post pa'Ssi'eren *: TM * the * friction between the wiping surface the cleaning element and the visible surface of the reflector Keeping the distance between them as small as possible and constant are small at both ends of the cleaning device Wheels placed on the axle, which roll on the surface of the delineator post during the cleaning process.

The advantages achieved by the invention are in particular that the rectangular reflector as the most important part of a Road guidance posts, always an optical one for the driver Help is to recognize the traffic area in any weather and in the dark. The attached device requires no maintenance .. it can also be retrofitted on the side of the road the delineator post. If delineator posts are machine washed with the attached device, the i

Device can be removed and re-attached with just a few manipulations.

The device shown in this application is a push wiper, in which the plate 5 acted upon by the gust of wind sits on the cheese of the delineator post The same principle of action - and its individual parts similar a push wiper, the plate 5 sits at the rear of the delineator.
