Abstract

In a guiding system in particular for partially sighted persons, a cast stone (1) is provided with a recess (4) for accommodating at least one LED lighting system (5) by means of a suitable molded body in a production plant, or an LED lighting body is introduced in the course of the production of the cast stone.

Description

Control system made of concrete workpieces

Description :

The invention relates to a control system made of concrete blocks, which is suitable to provide even in low light conditions visually impaired people optimal orientation in a traffic area.

Visually-handicapped and blind people need the three basic information Go, Attention and Stop for orientation. This information can be through walls, edges, borders or through borderlines between high-contrast floor coverings such as

between plate and plaster pavement with a long stick tactile be detected. In difficult places, these functions should be characterized by special high contrast

Soil indicators are adopted.

Go! is usually signaled by the sidewalk surface marking edges, walls or Borden, which act as so-called. Inner or outer guideline. If the environment is not clearly tangible and coherent existing

 Guidance offers guidance, for example, because business expenses are in the way, in large squares or often at junctions, should there especially

trained guide strips are installed for guidance.

Attention! can mean a hint, a branch, but also a warning. This information is through

Attention fields or strips of pimples or collection strips of ribbed plates regularly signaled.

Stop! is usually indicated by a curb or a step.

CONFIRMATION COPY For motor impaired people can for

However, visually impaired and blind people can be an obstacle to important steps or shelves as a guide, as these people need the least possible height difference between the individual traffic areas.

Many visually impaired are mainly oriented visually, especially when they are at the same time

Nahfeldsicherung use a long pole. But since in visually impaired people often also

 Color recognition capability is limited, only a color deviation, z. B. from red to gray, the

Requirements for the optical contrast do not meet.

Optical contrasts should therefore be primarily light-dark contrasts, especially luminance contrasts. At the same time, bright information on a dark background is generally the more recognizable one.

Against this background, DIN 32984 explains so-called floor indicators with a high tactile, acoustic and / or optical contrast, such as in the luminance or in the color between adjacent floor coverings.

Furthermore, visually impaired and blind people often require guidelines for longitudinal guidance in order to be able to orient themselves. These can be existing orientation aids such as walls,

Edges, rims or tactile detectable companion plantings may be like green strips. There, where existing on-site

Orientation aids are not closed, takes over a coherent additional system in the form of guide strips from, for example, ribbed plates, the function of a guideline.

Guide strips are lined up in the running direction

Floor indicators with a longitudinal profile, eg. One

Rib profile. They guide visually impaired and blind people along certain routes and have at the same time a demarcation and on platforms and other traffic systems

Warning function. It is a fixed obstacle Minimum distance of 60 cm. The width of such guide strips is 30 cm.

Ribbed plates have an upper surface of parallel ribs, which, however, due to their structure in contrast to

Nubbly plates with the feet are not palpable. Therefore, it is necessary that the axial dimension between the ribs is dimensioned large enough so that these plates are safely palpable with a long pole. Ribbed plates are laid so that their ribs protrude above the level of the walkway. However, the axial spacing of 20 mm mentioned in DIN 32984 is already too low due to the different long-pole tips on the market.

Center distances of 50 mm to 60 mm should be suitably adhered to. The rib itself has one

trapezoidal cross-section and should have a height of 3 mm to 5 mm and a foot width of 20 mm.

The small-sized ones described in DIN 32984

Grooved plates or sine plates correspond. also no longer the current needs, since they are barely palpable with the usual pole tips today. That's why they should not be used anymore. The invention has for its object to provide a barrier-free control system for visually impaired and old people, so with this group of people in bad

Visibility an orientation in traffic

is easily possible.

This is inventively achieved in that are arranged on known control systems made of concrete blocks corresponding flexible or rigid LED lighting fixture, said gem. of Claim 1 is based on the fact that such a concrete block that for a recording at least one

 LED lighting system required recess obtained by a suitable molding in a manufacturing plant.

Alternatively it can be provided that a LED lighting fixture is already introduced during the production of the concrete block.

The dependent claims represent advantageous embodiments of the control system according to the invention.

An advantage of the guidance system according to the invention is the special combination of the LED illumination system with the

Casting stone, which as a static element of load transfer has the same shape and dimensions as the previous ones

 Having concrete guide stones and so can replace them in a simple manner.

As a result, the specifications remain through standards and guidelines for barrier-free building and the requirements of the

 Blind bandages, for example, untouched with regard to the arrangement of ribs of a Leitstein.

In addition, the production of such a control system is simple, as appropriate, the individual elements of

LED lighting system pre-assembled and as

 LED lighting fixture can be inserted into the recess of the concrete block and cast, alternatively, that an LED lighting fixture in the course of the production of the

Concrete block is introduced and thus forms with this an inseparable unit from the outset. Regardless of the creation of moisture or mechanical stress such as traffic loads can not weaken the control system according to the invention.

The LED lighting system includes a variety of

light emitting diodes, LEDs arranged side by side. The LEDs are preferably arranged so close together that the LEDs are almost continuous

Light band can be perceived. Alternatively or in addition to the dense arrangement of the LEDs, the

LED lighting system include means that scatter the light of individual LEDs, giving the impression of a continuous light band arises. Examples of such means for light scattering are, for example, scattering foils which are located between the LEDs and the light-emitting surface of the

LED lighting system or on the light-emitting

Surface of the LED lighting system are mounted.

 Alternatively, the LEDs may also be cast in a transparent resin to which light scattering particles have been added. An LED lighting system, which is designed as a continuous light band, has the advantage that the

Guideline function for visually impaired persons to discrete light sources is improved.

The control system according to the invention will be further explained with reference to the drawing, the sole FIGURE 1 is an isometric view of a concrete block with an adapted

LED lighting system reproduces.

Fig. 1 shows a trained as a guide stone concrete block 1 of a control system. In the illustrated concrete block 1, rowed bottom indicators 2 are arranged in the running direction with a longitudinal profile in the form of a rib profile. The middle longitudinal profile 3 is factory with a

Recess 4 has been provided, the inclusion of a

LED lighting fixture or LED lighting system 5 is used. After preparation of the concrete block 1 in the concrete plant under the provision of suitable moldings for creating the

Recess 4 is introduced either at the construction site or already in a manufacturing plant, for example. A flexible LED light strip as LED lighting system 5 in the recess 4 and preferably shed there. This LED strip light is designed so that it takes over the function of a central rib of the concrete block.

This LED strip light allows in particular visually impaired people in bad weather conditions and at night optimal guidance in the traffic area.
