DE202005010029U1 - Indicator device for indicating the ground to people with impaired vision has a covering plate with a grooved section, a base element and rubber sections - Google Patents

Abstract

A covering plate (1) has a grooved section in a lengthwise direction with supports on the sides and conical supports in a center area. A base element (2) has a side recess for inserting an LED strip (6). A first rubber section (3) fits between the conical supports for the covering plate and a basic module. A second rubber section (4) fits in an edge area.

Description

soil indicators (Blindenleitplatten) have the function of visually impaired persons Railway stations, stops and public seats to entry points, transitions and Crossroads lead, and fulfill on edges and curbs a warning function. The surface structure The plate serves the visually impaired for tactile perception with the Blindstock or the foot surface. she can be done in the form of grooves, nubs or material changes.

The Plates, which are mostly made of solid or plastic, are flush with the surface laid the plaster.

Not always can the indicators are touched with the help of a blind stick. This is justified with both soiling and / or insufficient surface texture.

Of the in claim 1 protection invention is based on the problem to develop a soil indicator that will send further signals to the visually impaired gives.

With the invention it is achieved that, on the one hand, a further tactile perception is made possible. This is due to the storage of the cover plate ( 1 ) on vibration profiles ( 3 ). On appearance, these vibration profiles ( 3 ), and the person entering feels the sinking of the mat ( 1 ). Without stress on the cover plate ( 1 ), this goes back to its original position. In addition, the floor indicator has acoustic signals that occur when crossing the surface structure with a blind stick. For this purpose, the cover plate ( 1 ) on vibration profiles ( 3 ) and arranged over a cavity. As a third way of perception, the indicator looks optically. This is indicated by an inserted LED strip ( 8th ), which is inserted in the stone accompanying the groove structure. The lighting should be possible and changeable in different colors.

the Visually impaired people are provided with a soil indicator, which is tactile, audible and visually perceptible.

One embodiment The invention is explained in the drawings 1 and 2.

drawing 1: Floor plan of the floor indicator

drawing 2: step through the bottom indicator

In the drawings, the soil indicator with basic element ( 2 ), Cover plate ( 1 ) and intermediate vibration profiles ( 3 to see). The cover plate ( 1 ) closes the indicator upwards. The indicator element can be adjusted in length and orientation by a corresponding laying of several elements. Laterally, the basic element ( 2 ) has a recess into which the LED strip ( 6 ) is installed. Parallel to the laying direction are between cover plate ( 1 ) and basic element ( 2 ) Profiles ( 4 ), which serve as spacers.

Explanations to the cut:

1

Cover plate, with grooved profile in longitudinal direction on the sides and by conical supports in the middle area

2

basic element with side recess for insertion of the LED strip

3

rubber profile between the conical supports of the cover plate and the basic module

4

rubber profile at the edge

5

sealing profiles in the channel of the LED strip

6

LED strip Corean molded LED strip

General Explanations

The The idea of developing a multi-perceptible guide-line emerged when visiting various Stuttgart underground stations, where a Leitstreifensystem made of plastic, both tactile and acoustic is perceptible.

aim It was now, the valued by blind people with the properties Building material to unite concrete. The sound that comes from driving over of the profile with a blind stick, could, after a few tries can only be achieved on the model if an oscillating cover plate is applied becomes. Therefore, the stone was now in a trough-like basic element and a profiled cover plate divided, which is connected by rubber profiles are.

By a reduction of the rubber profiles, by means of a conical support, could even create another tactile perception possibility be: When you step on the stone this lowers slightly.

One Problem of many stops is that schedule displays and similar From the platform are difficult to see. For this reason was added a visual signal generator on the side of the basic module There is a recess in which an LED strip is inserted becomes.

Modern LED technology even allows a color change, which allows individual lines to be displayed when entering the station. Not disabled, but also the deaf can assign the incoming train to a particular line very quickly.

This novel guide strips possible So in the dark, with heavy pollution, high noise, etc ... a secure perception.

The stone was part of the in-depth draft _" barrier-free building" at the FH Karlsruhe, supervised by Prof. Dr.-Ing. G. Loeschcke, developed by the students Martin Birnbach and Christian Dorst It is intended to realize the stone with the support of an appropriate company.

Claims (3)

Floor indicator with tactile, acoustic and visual perception possibilities, characterized in that the cover plate ( 1 ) on vibration profiles ( 3 ) is mounted, which allow an up and down movement. Floor indicator according to claim 1, characterized in that the cover plate ( 1 ), outside the Auflagungskegel, has a thickness of 2-3 cm, thereby creating a cavity. Floor indicator according to one of the preceding claims, characterized in that in the basic element ( 2 ) a recess for receiving an LED strip ( 6 ) is provided.
