Description

Wall chart, especially for schools, for showing road traffic processes To make children and young people familiar with the traffic regulations as early as possible to make and thus to educate the correct behavior in traffic, becomes Recently, the implementation of corresponding teaching courses at all schools has been demanded and partly already planned. This requires suitable teaching aids with which both the various traffic processes possible at an intersection or the like as well the traffic junctions themselves are shown quickly and clearly in various forms can be.

In this regard, the usual practice up to now has been on school blackboards too cumbersome and also too instructive. The same goes for viewing and explaining of picture panels. Experience has shown, however, that the interest of the young course participants and ultimately also the success of the lessons, significantly reinforced if through suitable visual and teaching aids, the instinct to initially be more playful, will later also be addressed to creative collaboration.

The primary purpose of the present invention is to achieve this Aim by suggesting a roughly square wall chart with suitable, designed Partial patches that can be moved on it and in such a simple way and fast way intersections and other traffic junctions in manifold Allow creation or modification of the design.

The more or less wide spaces between the partial areas illustrated main and secondary roads etc. could then do At will with. corresponding models in front of vehicles, pedestrians, traffic signs and the like, whereupon the right or wrong behavior of the shown; Road users are explained, discussed or queried.

A teaching and illustration board of this kind is of course also for the traffic instruction in. Driving schools and the like. As well as for the reproduction of actual Traffic accidents can be used in court.

Particularly suitable for building up. stepped by road junction unodels A single version of the chart has been found, with which the individual, Teidflächer Pieces can be put together to form four squares near the corners of the table, of, which the pieces of a square independently of each other in the corresponding quarter the board can be moved.

In this way, those that can be put together to form a square are expediently created Partial areas @ parts each, by dividing the square in two along an approximately diagonal straight or curved line running to the center of the board.

In this way one can obviously enter near the center of the board Ver'kehreiknobenpunkt with up to eight outgoing streets. Included is also the width of each: street to be chosen arbitrarily; Tram lines, Traffic islands and the like can, like the vehicles etc. in, the model in particular entered, or inserted: to be.

In order to have a special packing of the patches when putting down the wall chart to save and also, in order not to let individual pieces get lost, are, in the latter, expediently built-in guides, which on the board in, to a certain extent Extent a prescription, but not a: allow removal of these pieces ..

If one wants to use magnets, which in itself for this purpose known, but at least quite expensive, avoid, so it follows in further Design of the invention as the relatively simplest and therefore also the most economical The solution to this problem is as follows: The patches are hollow and in the area a larger recess on its underside over one protruding from the board Bolt movable; the bolt is also in a long slot of a plane, which is hinged inside the partial surface piece and through the area of the recess is pivotable.

The fixed guide pin is approximately above the elongated slot screwed with a metal plate, so that the partial surface is normally cannot be withdrawn. On the contrary, by virtue of the spring action, the elongated slot lever Carry the patch so tightly to the plate. be pressed., the same as with magnetic Attraction just a pure sliding movement (parallel displacement and rotation) is possible without any rattling.

In the manner described, a mobility is achieved that is completely sufficient for the intended purpose and also an economical mass production of the individual parts stamped from sheet metal or injection-molded or pressed from plastics allowed for the tours etc. The board itself can e.g. B. consist of a chipboard that on a multi-part stiffening frame Wood or metal profiles attached and given if still with a double floor and folding or Drawers for storing associated Models, plates and dg1. provided aest. The subject of the invention is shown in the drawing on the basis of an exemplary embodiment light, which is explained below. In detail shows Fig. I The front view of a school board with set partial areas i, Fig. 2 is the rear view of one of the partial surfaces on a larger scale, Fig. 3 a. corresponding cross-section along I-1 of Fig. 2 with the panel behind. The board itself consists of the square Pressboard a with a smooth surface, the back wall b and the surrounding area, beyond the level of the Plate a protruding edge frame c z. B. made of wood. For the inner stiffening of the approximately 1 square meter platform Between them there can still be an unsigned one Be arranged cross frame. On the surface of plate a there are eight parts surface pieces d displaceable and rotatable. These essentially have the shape of right-angled leagues. Triangles and can be divided into two to four Push the partial squares together, one of them each is located near a corner of the table and one about running diagonally to the middle of the board, resp. having curved dividing line. In Fig. I, in the middle of the panel, suitable shifting the individual patches of area d z. B. that Model part of a traffic junction with six there were streets of different widths shown. In addition, on the upper and right on the edge of the table some cross streets are left out, which are used as diversion roads in class interprets and can be used. The adhesion of the patches d is im can be seen individually in Figs. 2 and 3. The three- . corner d are designed as a hollow body. Her Rear wall e has a larger recess f , in _the one from the plate a protruding solid Bolt g protrudes so that the Teid surface piece d on the plate a a correspondingly limited possibility of movement. Inside is in addition, a lever h at a pivot point i steered through the whole area of take f is pivotable. He leads in, one Long slot k always serves as the fixed bolt g. On the Gevvi: ndeende this latter is above, in, Ab b .2 aaso below the lever h a plate l is placed screws, creating a separation between bolts g and long slot k and thus a lift-off, this part surface piece d from the plate a impossible power is. Around the plate l screwed onto the bolt g to secure against unintentional loosening, is the latter is expediently not designed completely flat, but in suitable places, like this downwards bent that it is not opposite to the lever h can turn. In Fig. 2 and 3 z. B. to see how an s-ector-shaped part m is folded into the elongated slot k .

Takes place of the assembly of plate a and Tei.lführungsstücken d by d every part surface piece with levers h and initially loose platelet l as to the plate a is set such that decoding g relevant, plugged from the rear side of the plate a through his prepared bore pin in that, plate l can be screwed. Then the head piece of the bolt is screwed to the back of plate a (v.1. Fig. 3). If necessary, loosening can of course be accomplished in reverse order.

In order to allow the partial surface pieces d to slide easily on the plate a and not to damage the latter in the process, the underside e of these pieces d is underlaid with several felt pads n.

It can also be seen from Abh. I that all the bolts g fixedly mounted in the plate a are arranged symmetrically on a certain circular line o around the center point of the panel. Otherwise, for a better overview, the levers h are only indicated schematically in the individual guide pieces d.

The entire filtration mechanism is completely hidden from the outside and thus attached invisibly. A distraction for the student from the subject to be treated Themes cannot therefore be evoked through him.
