Magnetic boards of the following type are known: «The board consists made of iron or sheet iron. On the board are placed} 1.) Permanent magnets. 2.) Body into which permanent magnets are whole or are partially used. 3 ·) Bodies on which permanent magnets are placed.

The need for magnetic boards for classrooms and others Purposes to use constantly increasing · If nevertheless in that Most of our schools magnetic boards are not used, this is only due to the question of cost. The purpose of the object according to the invention is a significant price reduction for magnetic boards, which by a different manufacturing process is achieved.

1 ·) The magnet bodies best known in schools are probably the circular plates made of plastic or wood into which permanent magnets are inserted. They are used for arithmetic, geography, chemistry and some other subjects. The price for a single such plate is currently 5.00 DM (see brochure of the educational institute Köster & Qo., Munich 8 (page 3, above: circular plate 5 cm $ and 6 mm thick, two-colored, adhesive on both sides, according to Schneider-Garthe .)) Thanks to patent number: 919754- and file number: H 10 161 IX b / 42 η, the Hamburger Lehriaittel ###: # firm Schul-Knickraann is today able to sell a magnet plate for a price of 1.00 DM. (See brochure " Schul-Knickmann * s Magnet-Tafel" (page 7, see whether a circular plate 3 »5 cm in diameter and 6 mm thick, two-colored, adhesive on both sides.)

One purpose of the article according to the invention is to provide a magnetically adhering plate with the above Sizes are offered for 10 to 20 pfennigs instead of 3.00 DM or 1.00 DM. (Production price: 5 to 10 Pfennig I) This is achieved by reversing the procedure. So far, the board represented the metal surface and the magnetic body was scheduled. According to the subject matter of the invention contains

now the (CafeIflache will be the magnets and metal bodies, scheduled »

Execution game t

In a wooden plate (auB.-ffovopanplatte -of 60 χ 60 cm and 6 mm thickness) 100 holes with a diameter of 14 mm are drilled at a distance of 5 cm, in such a way that 10 rows with 10 holes each arise »In each of these holes a circular permanent magnet of 14 · mm 0 and 6 mm thickness is inserted ·! times the insertion the magnet, the surface is filled and sanded and - if necessary - painted with blackboard paint. One produced in this way (Dafei is in comparison to the previously known metal plate around 10 DM more expensive, there but the production of all associated adhesive bodies is now many times cheaper, for the magnetic board as a whole a significant price reduction achieved »The double-sided, two-tone adhesive body is used the common tin cans. When punching out the tops For example, yellow sheets are used (lid) and red sheets when punching out the lower parts. The two-tone ones made in this way Cans cost 5 to 10 pfennigs each, depending on their size. If necessary, the top and bottom are put together when assembling glued »They are in no way inferior to the previously used magnetic platelets at 3 · OO DM or 1.00 DM only the further advantage that if individual tiles are lost, these can be relocated with minimal loss of money can. (100 adhesive plates of this type therefore cost DM 5,00 to DM 10,00 to manufacture, and about that to be sold on sale Double: 10.00 DM to 20.00 DM. This means that the following can be compared:

As previously known & Co *.): 100 tiles. 300 DM According to the subject matter of the invention: 100 tiles 30.- DM (20.00 DM for 100 tiles + 10.00 DM table price increase.)

or:

As previously known (from Schul-Knickmann) r 100 tiles: 100 DM According to the subject matter of the invention; 100 tiles: 30 DM

This considerable price reduction is understandable through the labor savings that result from reversing the procedure is achieved.

The previously used process for the production of the 1.00 DM platelets was:

l? i33252? H.6.-!

1 ·} Make wooden panels and drill.

2.) Get magnet »

3.) Insert the magnet or glue it in * 4) Fill the front side with a spatula.

5.) Sand the front.

6 ·) Fill back the back · 7 ·} Sand the back.

8.) Spray paint the front (two or three times).

9.) Spray paint the back (two or three times).

This list makes it clear how often each individual tile is had to be taken in hand until it was completed, e.g. during the preparatory filling and sanding work and then also with the spray paint on both sides.

For the tin can production, however, all facilities of industrial production are available, so that manual work is hardly needed.

However, inserting 100 magnets into the fafel is considerably cheaper than inserting into 100 small individual plates, because the filling and sanding of a large area are unequal can be carried out in a simpler and more time-saving manner. In addition to this advantage, there is also the change. It does not need - as with the Small plates so far - front and back to be machined, but only one side of the board is filled and sanded. As a result, there is no negative part in the way of working afterwards, since the platelets (colored tin cans) - as before - can be applied on both sides.

The magnitude of the advantage brought about by the subject matter of the invention occurs, the more different types of adhesive bodies are used for comparison, the clearer it is.

2.) In schools, as is well known, calculating money can be done by using enlarged sticky coins are shown to the whole class. (See patent application file number N 10 161 IX b / 42 η) · Until now, every coin had to be provided with a magnet. When using the object according to the invention this edition is omitted. The enlarged coin image printed on sheet metal is punched out in the usual way. The easy-to-grip, enlarged coins are therefore tin cans that are printed with the coin image. Your manufacturing price is considerably below that of the previously known magnetic coins.

3) In elementary arithmetic lessons in elementary school there is a level of development in which it is advantageous to be able to put tens and other strips in place of the individual numerals with a flick of the wrist.

Such a strip of ten, »5 x 50 cm, previously cost 20.00 DH (See prospectus from Köater & Co ^ .CSchneider-Garthe) p.3 above.) This becomes understandable through the use of many relatively expensive magnets. In the object according to the invention costs now such a tens are only about in production 20 Pfennig, because it is a metal strip that is only bent over on the sides for the purpose of greater strength and grip is *. Regarding the adhesive force and the achievement of the educational The objective is in no way inferior to the previously known 20 DM patrol ·

Fortunately, the advantage of the free mobility of the counting and adhesive bodies remains that the previously known ones Magnet boards show - apart from a very minor restriction - obtained by inserting the magnets, e.g. at a distance of 5 cm - in the case of the object according to the invention - and Use of the usual size of the tin cans, or sheet metal strips or other metal body is achieved that the metallic adhesive body - when moving in any direction - cannot fall down η, because they are even held by the neighboring magnet.

Placing a paper plan on the board - e.g. Outline maps in geography or score plans in music lessons are possible as before, since they appear as cities or notes stick to any point on the metal body (and not to the center of the closest Jumping magnet).

There is no need for the series of new possibilities that it gives to be cited in full, since the examples mentioned make it sufficiently clear that a very decisive one Price reductions can significantly increase the number of beneficiaries of magnetic teaching aids.

Mention should only be made of the reductions in prices that result from the production of metal panels or figures in the 1.) RaiiTnTehre-TTunterricht t plates, triangles, pike corners, squares. 2.) First reading »German and language lessons ; metallic whole-word tablets and metal plates that can be written on with chalk.
