DE202006008375U1 - Flexible blind directing plate has parallel slots and bars whereby slot is broader than neighboring bars and thickness of plate between baseplate and plate upper surface lies within specific range and side strip is arranged parallel to bars - Google Patents

Abstract

The flexible blind directing plate has parallel slots and bars whereby a slot (2) is broader than neighboring bars (3,3'). The thickness of the plate (1) between baseplate and plate upper surface lies between 1.8 to 2.5 mm. A side strip parallel to outside bars is arranged which has a thickness in the range of 1.8 to 2.5 mm. The plate is tough and flexible and made up of a homogeneous mixture of flexible hardening polymer and a filler with Moh's hardness in the range of 6 to 7.

Description

The The invention relates to a flexible Blindenleitplatte with parallel Grooves and webs.

From the DE 199 35 702 is a tactile Blindenleitsystem known in which the grooves and lands are arranged side by side in parallel and the webs of Quererrillensegmenten are crossed. The panels are usually made of frost- and foam-resistant glass fiber concrete.

The DE 103 52 204 describes a walkway plate with a profiling in the manner of a coarse tissue.

These and other known panels require complete relocation as a compact panel and are therefore in existing floor or walkway systems only with considerable effort to integrate.

Of the Invention is based on the object, a Blindenleitplatte with profiled surface form, which does not have the above disadvantages, but at the same time a safe guide for Blind allows and no tripping hazard.

The flexible according to the invention Blindenleitplatte with parallel grooves and lands is characterized that a groove is wider than an adjacent web, the thickness of the Plate between plate bottom and plate surface in the range of 1.8 to 2.5 mm, one edge strip parallel to the outer webs is arranged, which has a thickness in the range of 1.8 to 2.5 mm, and that the plate is tough-elastic is and from a homogeneous mixture of one into an elastic state curing Polymers and a filler with a Mohs hardness ranging from 6 to 7.

The Groove of Blindenleitplatte is trapezoidal, preferably with rounded edges. The area the groove has a sandpaper-like structure This structure corresponds to sandpaper of grain size P16 to P60. The groove has a height in the range of 3.7 to 4.3 mm. The edge strip has a width according to the width of the groove.

The Blindenleitplatte is further characterized in that the mixture consists of 70 to 85 wt .-% quartz sand and 15 to 30 wt .-% polymer.

The used according to the invention Polymers is a poly (meth) acrylate formed from cold-curing (meth) acrylate reaction resins.

Further It is essential to the invention that the quartz sand has a grain size in the Range of 0.5 to 2.0 mm, preferably from 0.5 to 1.8 mm.

The Blindenleitplatte invention is very thin and flexible and therefore can look good on all solid surfaces Stone, wood, concrete, granite, asphalt, used as slabs or sheets be applied, i. glued on. The plate can have variable sizes, however, is preferably in the range of 250 to 350 mm x 400 to 600 mm. The flexibility the plate is so big that they can easily and without breaking in both directions up to a semicircle can be bent. The plate therefore fits smaller ones too Bumps and leaves especially on existing floors without invasive intervention in the ground.

One particular advantage of the plate is that it through the Both edge strips with only very small height of 1.8 to 2.5 mm no risk of tripping and thus a smooth transition to the 3.7 to 4.3 high grooves allows. The total thus only 5.5 to 6.8 mm thick plate provides a innovative solution for the Range of existing ground and path systems.

A Slipping danger avoids the plate according to the invention by the rough, after Type of coarse sandpaper equipped tread of the part of the web surface, the the legs of the trapezoidal sides of the bridge connects. The trapezoid is preferably an isosceles trapeze.

The Plate of the invention is also durable and puncture resistant and shows due to the corresponding degree of filling barely with the hard filler Wear.

The Forming a wider groove in relation to the adjacent webs ensures a good leadership of the long stick of blind or weak-sighted persons and carries with it also essential to the solution the technical problem of the invention.

The Laying the blind guide plates according to the invention takes place one behind the other in the direction of the parallel grooves, through the webs and grooves are formed. The bonding of the plate with the soil underneath is usually made with a suitable one Glue, at e.g. Sheets of (meth) acrylate with appropriate acrylic adhesive.

A preferred plate material is, for example, a lime-hardening (meth) acrylate reaction resin according to EP 0 965 619 produced.

The Invention will be explained below by way of example. In the accompanying drawings demonstrate

1 two plates of the invention in plan view;

2 Sectional view after aa.

1 shows two successive plates, which can connect in the direction of the grooves more plates. The almost seamless abutting bridges 3 or 3 ' in both plates represent the actual tread surface and each show the sandpaper-like surface structure, as they are for the surface 7 is shown by way of example.

The edge stripes 6 and 6 ' When approaching blind persons to the plates or when carelessly walking through normal sighted people do not pose a risk of tripping. They lead blind persons without difficulty to the slightly higher bars 3 . 3 ' the plate 1 above.

Through the wide grooves 2 a good guidance of the long stick is made possible while running in the direction of the grooving.

In 2 In the plate cross-section, the very small plate thickness becomes visible, after which the distance between the plate bottom 4 and the plate surface 5 only 1.8 to 2.5 mm. Preferably, this distance is about 2 mm, so that at an advantageous height of the webs of about 4 mm, the total plate is only about 6 mm high and is therefore easy to apply in almost all conventional floors and ways and in no time without problems.

At the End of a laid track of Blindenleitplatten invention is usually a Attention field arranged that a change of direction or announces another special feature. After that you can the plates according to the invention continue in the new direction or in an interior of a public building be laid and glued in the same manner as described above.
