The fire "refers to a facility., With which you can design logical processes, e.g. electrical circuits, in a simple way and present them clearly can, . ■

Logical processes are usually represented in the form of drawings, for example on paper. This has the disadvantage that when changes are made to what has already been drawn - partially deleted (erased) or, in the worst case _9, the design must be completely discarded and destroyed are needed again in the same way in the new draft, must be re-recorded in this pail. With this, the mentally constructive work of developing a circuit (a logical sequence) is hindered and delayed by a predominant part of routine interim work «-

This deficiency has already been recognized and circuit elements that are preprinted on transparent film have been developed that are based on the Wiring diagram stuck on ¥ i? Can be grounded. The disadvantage here is that loosening, regrouping and re-using is practically impossible. Eel many tasks, e.g. the creation of the block diagram of a control loop, however, it is desirable to use any, especially for. the concerned In the case of unraveled symbols or inscriptions used be able.

The latter possibility is given by a known one Device in the form of perforated panels into which small boards with tenons can be inserted. The boards are prepared to accept hand-made signs with any Labeling. The disadvantage here is that

2 -

the panels are raised above the perforated / plates and the application of drawing devices for inserting the connecting lines, which only result in the actual maintenance logic or «make it very difficult.

Another well-known device also has the laughing part, because the cards with the symbols above the board surface protrude .. 33s are the well-known magnetic boards. Further downsides here are that the adhesive elements can move easily and that liability is only given when using special paper ». . ■. "

The! Inflation is for the purpose all the deficiencies referred to fix "The device is designed _for that self-made plates made of any material on which Sehaltelemente and markers of any type can be displayed, can be assembled without additional fastening means on a panel to an example circuit diagram" The KLächencharakter of the plan is retained and working with a drawing device is not hindered. The signs can be removed at any time and reused without restriction.

The furnace is shown, for example, in Fig. 1 in cross section and Fig »2 in plan view» Fig. 3 shows an associated plate with the. Representation of a switch ™ element.

On a base board 1 of any size made of wood, strips 2, also made of wood, are fastened at regular intervals. The strips are provided with a phase 3 . In the case of the signs 4 to be inserted with the circuit symbols 5, the dimension c is slightly larger than the distance a "between the leading edges of the

mounted on the panel 1 covers 2 "Thus, the plates 4 can be joined by a slight pressure between the strips 2 and behind the front panel surface mark devices - such as rulers - can be used freely earthed x ^s / to the logical connections between the switching elements in 3? In the form of straight lines to be inserted. Where there are no signs, the lines run both on the strips 2. and in the spaces between them on the base table 1. The signs 4 can be removed at any time and reused as often as required.

Instead of wood, metal or plastic, for example, can also be used as the material for the board. The material must, however, meet the condition _v that it can be visibly labeled, for example with chalk. »If the material does not have this property from the start, the surface must be worked on: for example, wood should be painted with blackboard paint. ■ '.

The pegboard can also be made of solid material are made by incorporating hats that meet the 3? orm of the have 2 free seams between the strips » Also the board including the hats can be in one Mold can be poured or pressed. Used as material for the strips or an elastic material made of one piece for the board. «, phase 3 is not necessary (a = b). Rather, the lute width then only has to satisfy the condition that the dimension c is greater than the dimension b.
