Description

Means for Facilitating the Reading of Maps The invention relates to a device for facilitating the reading of maps. The establishment is particularly suitable for use when driving in a motor vehicle or the like.

There are several disadvantages with known maps. In particular the transition from one card of the usual format to another is very cumbersome, because when a card is over, the next one next to the one in the Card pocket located must hold until you are completely on the other card.

This disadvantage is eliminated by the invention, which has a device provides which of several, encompassing a larger area and in the middle the length and width of collapsible map part sheets without border and consists of a windowed map pocket that is in the window level and is dimensioned perpendicular to her so that she has an unfolded partial map sheet under the window record and two. once folded, adjoining partial map sheets hold on in their complementary position to form a new closed map image can. The map pocket can be arranged to be on top of the window remote side space for storing the unfolded, unused partial map sheets offers. The advantage of the device according to the invention lies mainly in that they allow you to quickly find your way around a map, especially with Transition from one map sheet to the next when driving a motor vehicle is facilitated.

In the figure, one embodiment of the invention is for example shown. Fig. I shows the subdivision of a map of the German Empire according to the invention: Fig. 2 shows the design of the card parts, while Fig. 3 shows diagrammatically the map pocket with window.

The designation of the partial map sheets of the map of Fig. I of the German Empire is set up in the exemplary embodiment in such a way that the parts from west to east with capital letters A, B, C, D etc. and from south to north with numbers i, 2, 3 , q. etc. are designated. In this way, each partial map sheet is clearly identified with a letter and a number in a manner known per se. In addition, in the manner shown in Fig. 2, the name of the relevant place of the sub-district concerned, z. B. Basel, Cohnar etc., be indicated on the flag.

The partial map sheets each consist of four sub-parts that are drawn onto a coherent piece of canvas. The cards can be printed from the outset on cardboard and this cardboard can be mounted on strong canvas. The map pocket i shown in Fig. 3 is so large that it always shows four map sub-parts a, b, c, d in the window at the same time, so z. B. the whole partial map A i Basel at the same time. The bag should have so much interior space under the window that it can hold a completely folded partial map sheet under the window and hold two adjacent partial map sheets in their position that complements each other to form a new, closed map image. In addition, it expediently offers space on the side facing away from the window for storing the completely folded, unused partial map sheets.

The use of partial map sheets without a border, which can be folded in the middle lengthways and widthways, in conjunction with the designation system using letters and numbers, allows any parts of the entire map to be put together in a simple manner. For example, if you want to travel in the main direction from north to south and you are currently on partial map sheet b to go over map section d to the map section not shown south of it, you would find partial map sheet in pocket i fold over line II, slide it upwards and similarly pinch the sheet containing the part to the south of it and slide it into the pocket below sheet a, b, c, d. The map parts that are not in use can be stored in a special card holder (box, bag, etc.). To facilitate the search, the designation with a letter and a number, z. B. Aq., D6, Fg, etc. Removal is made easier by knowing that in the north-south direction all partial map sheets are with the same letter and are consecutive. Numbers (A9, A8, A7 , etc.) and, in the west-east direction, all leaves are designated with the same numbers and consecutive letters (A5, B5, C5, etc.). If, for example, the map section C3 is currently in use and a path leading to the east has come to an end, you know that section D3 follows in an easterly direction, which you can easily find in the card index and remove from it. Instead of folding over the partial map sheets according to line II (Fig. 3), you can of course also fold over according to the perpendicular line II-II and assemble the entire map visible in the window of the map pocket from two similarly folded parts that meet along line II-II.

This makes the transition from one part of the map to the other special makes it easier for the individual sheets to be printed to the edge or with the card are pasted, d. H. that the previously common white border is missing. Since the card is with cuts off the edges of the sheet, two side-by-side sub-rectangles appear (even when folded) like a map.

The reduction of the maps by dividing them into partial map sheets in connection with the unique designation of each sheet with two symbols the map parts are particularly handy and easy to use and facilitate removal, Handling and reading.

Claims (2)

PATENT CLAIMS: i. Device to facilitate the reading of maps, consisting of several, encompassing a larger area and in the middle of the Length and width according to collapsible partial map sheets without margin and one windowed map pocket that is in the window plane and perpendicular to it is dimensioned in such a way that it can accommodate a fully folded partial map sheet under the window and two adjoining partial map sheets in hers, once folded can hold on to a new closed map image complementary position. 2. card pocket for the device according to claim i, characterized in that on the side facing away from the window there is space to store the original, offers unused partial map sheets.
