Abstract

PURPOSE: To prospect the position of a thin part rapidly by providing a scale at least on one line, providing a display unit along the line movably, and extending the unit in horizontal direction for the line. CONSTITUTION: A display unit has a cross mark formed by two cross lines 17 and 18. The cross line 17 is provided so that it is extended in vertical direction and moves along a scale 13 extended in horizontal direction but the cross line 18 is provided so that it is extended in horizontal direction and moves along the scale 14 being extended in vertical direction. Also, symbols 11 and 12 and scales 13 and 14 of a large lattice 4 are arranged so that they correspond to a thin part 15. Therefore, a cross point 19 that is formed by the cross lines 17 and 18 moves the cross line 17 being extended vertically by a charger (g) of the scale 13 and moves the cross line 18 that is extended horizontally to a specified point of the scale 14, thus performing direct prospecting. In this manner, a required thin part 15 can be accurately determined by the cross point 19.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention provides a device for locating the position of details drawn on information material, in which said material is located at least twice by a large grid of lines at angles to each other. The present invention relates to a device which is divided into four squares, at least one of the squares containing said detail.

BACKGROUND OF THE INVENTION Devices such as those described above are used in particular for reading maps and street maps. The device is designed, for example, as a lamp that is directed at the information material. With such a lamp, the information material can be sufficiently irradiated. This illumination facilitates the localization of details drawn on the large grid on the information material. By using this large grid it is possible to perform a position search over a relatively large area on the information material. However, in many cases when large grids are used, long periods of darkness are required to locate these details. This wasted time can be especially frustrating for drivers on the road when they are suddenly trying to find the street they are looking for.

OBJECTS OF THE INVENTION The object of the invention is to improve the device described above so that it can be used to rapidly locate the required details.

(Means for Solving the Problem) According to the present invention, the above object is achieved by providing a scale on at least one line, and movably arranging a display unit along the line having the scale. This is achieved by having the units extend transversely to said lines over at least one square of the large lattice.

This unit can be slid along said line to the point on the scale where the required detail is located.

In this way, localization of details on the information material can be carried out without having to cover it with a small grid system. Such small grid systems greatly obscure the information material. The reason for this is that a large number of lines are required to overlap the details shown on the information material, making it difficult to determine whether one particular line represents a sub-grid line or the required detail. This is because. In contrast, with the device of the invention, only a large grid is used, within which detailed positioning can be easily carried out by means of the line graduations.

According to a preferred embodiment of the invention, the indicator unit is formed in the form of a filament. This filament can be moved over the large grid without obscuring the viewing of the details of the information material. Even if the side portions are small, their clarity is not lost due to the grid lines;
Location exploration can be easily performed.

Other details of the invention will become apparent from the embodiments described below with reference to the accompanying drawings.

(Embodiment) A device mainly consisting of a display unit 1 is arranged on a street map 2 so as to be movable horizontally with respect to the vertical direction of the street map. This indicator unit 1 is in the form of a filament that can be moved along a line 3. This line 3 is bounded by a large grid 4 printed on the street map 2,
and approximately equidistant lines 3a, 3b, 3c - these lines define a grid. The lines 3a, 3b, 3c extend substantially horizontally, and the lines 5a, 5b, 5c are vertical.

It intersects with 5d. Horizontal lines 3a, 3b, 3c are approximately perpendicular to vertical lines 5a, 5b, 5c, 5d. One grid grid 10 of the street map 2 is arranged between each of the four intersecting section lengths 6,7° 8,9. These lattice holes 10 together form a large lattice 4. Each grid square is reference number 11. '12, one of the numerals being for a row of grid squares 10 arranged perpendicular to each other, the other reference numeral 12 being for a row of 10 grid squares arranged perpendicular to each other. This is for a row of 10 grid squares. For example, the capital letter of the alphabet is used as the reference numeral 11 for grid squares arranged perpendicular to each other, and the - Roman numeral is used for rows of grid squares 10 arranged horizontally. .

Line 3.5 has graduations 13.14. The scale 813 extending horizontally consists of, for example, lowercase letters of the alphabet, while the scale 14 of the line 5 extending vertically consists of Arabic numerals.

These graduations 13, 14 can be arranged in such a way that their corresponding counts start from the beginning of each grid square 10. Therefore, each part length 6.7.8.9 of m3,5 is, for example, in the horizontal direction, the lowercase letter "a" of the alphabet.
'', and in the vertical direction, the number ``1''. If partial length 6.7.8.
9 are of the same size, the scale 13.14 ends with a number or letter, for example "m" or 1113 II.

The display unit 1 has at least one horizontal line 3a, 3b
, 3c.

In the street map 2, a detail 15, for example “Ne(1(!r
If the Wall is to be searched, place the letter n G n on the scale 13. In this way, display unit 1
The location of the required detail 15 can be searched along. This required detail 15 is determined at a specific position of the display unit 1. All the rope sections 15 of the street map 2 are included in a list that is not shown. This table not only contains the symbols 11.12 of the large grid 4 for each detail 15, but also graduations 13.14, by means of which the position of the rope section 15 can be quickly detected. Regarding this point, each grid square 10 scale 1
3.14, for example, as shown in Figure 1, the letter “a”
Alternatively, it is conceivable to start with the number IT I IT. However, for the line 3°5, along its length extending through the entire street map 2, the said symbols are selected in succession, and the scale 1 of successive grid squares 10
3.14 can be made to begin with the letter or number following the last letter or number of the grid square 10 before it. Depending on the size of the section 16 of the street map 2 to be examined, each line 13° 14 extending along the edge of the section 16
The symbol alone is sufficient. In this case, display unit 1
must be of such a length that it extends across the entire section 16. However, if each grid square 10 has divisions 13.14 to at least partial lengths 6, 7, 8, and 9, then the length of indicator unit 1 is at least as large as the length of grid square 10. It is sufficient to make it correspond to the size. The advantage of shortening the display unit 1 creates the problem that the clarity of the street map 2 is reduced. The reason for this is that the number of scales becomes large.

In order to accurately determine the position of the required detail 15, the display unit 1 is essentially assumed to have a cross-like shape formed by two intersecting lines 17,18. One line 17 extends vertically and is arranged to be movable along the horizontally extending scale 13, while the other line 18 extends horizontally and is movable along the vertically extending scale 14. It is arranged so that it can move along. Large lattice 4 symbol 11.12
Since the scales 13 and 14 are arranged to correspond to the required rope sections 15 in the list (not shown), the line 1
7.18 The intersection point 19 formed by
The letter 3 “Q” moves to II, while the horizontal line 18
can be directly probed by moving it to a specified point on the vertically extending scale 14. In this way the required detail 15 is accurately represented by the intersection point 19. In this case, in said list (not shown), the arrangement of the symbols 11.12 or the scale 13.14 is determined for the detail 15, for example in the case of a street, by selecting the arrangement obtained from the list. , intersection 19 is approximately section 16
It may be located in the center of a street that extends through the area.

Furthermore, the scale 13.14. can be provided on a base 20 that rests on the street map 2. For practical reasons, the base 20 has a size corresponding to the size of each grid square 1.O. I! The i117°18 is movably disposed on the base 20. This base 20 is arranged in such a way that its delimiting edges 21, 22, 23.degree. 24 extend along the subdivisions 6, 7.8.degree. 9 of the grid squares 10.

Lines 17.18 are thus drawn on scales 13.14 of base 20 according to information obtained from a table (not shown).
You will be able to move the top.

For practical reasons, the base 20 is designed as a magnifying glass.

This base can be, for example, a magnifying glass made of transparent plastic. By structuring the base 20 in this way, the position of the small detail 15 can be accurately determined from its placement on the street map 2.

The base 20 also has three W4s superimposed perpendicularly to each other.
63.64.81. These layers 63,
A gap 65.66 is disposed between the upper surfaces 74.64 of the lower layer 63.64 on one side, respectively.
75 and the lower end surface 82.83 of the upper layer 81.64, respectively.
The world of flesh has been transformed into a world of flesh. These end faces 74, 75 and 82° 83 are approximately parallel to each other. the void 65,
66 is the upper end surface 82.83 and the lower end surface 74°7.
5, there is a distance sufficient to allow the line 17.18 to move within the air gap 65.66. The upper end surface 82.83 and the lower end surface 74.75 which define these gaps 65.66 extend substantially parallel to the bottom surface 84 when the base 20 is placed on the street map 2.

Each layer 63, 64, 81 is a spacer member 67, 68, 69
One of the spacing members can be placed at each corner 70° 71, 72, 73 of the rectangular shaped base 20. In this case, the spacing members are, for example, steel bolts, which are connected to the corners 70, 71, 72.
layers 63.6 that can pass through the through holes of 73 and be separated from each other;
4.81 can be screwed. By structuring the base 20 in this way, the above 1163
．． The advantage is that the end faces 74.75 and 82.83 can be produced inexpensively, as long as the ends 64.81 can be separated from each other. However, this base 20
can be considered to be formed as a block comprising three layers 63, 64, 81 and the voids 65, 66 to be molded in the form of slots within the block. In this case, the end faces 74.75 and 82.83 are carefully formed and
The entire block forming the platform 20 remains transparent,
It is important to be able to inspect the street map 2 through this. In fact, said block has an arcuate shape on its bottom surface 84 and opposite surface 85, so that the base becomes a magnifying glass for magnifying the details 15.

If the gaps 65, 66 are in the form of slots, they can extend at right angles to each other through the blocks constituting the base 20. The width of each slit is narrower than the entire width of the base 20, and each of the layers 63, 64, 81
are interconnected by edge sections extending on both sides of each of the two slots. In this case, the spacing member 67.6
There is no need to provide 8.69.

In any case, the width of the slots should be selected to correspond to the dimensions of the grid squares 10. In this way, the viewing section can be maintained between the edge sections or spacing elements 67, 68, 69 whose dimensions correspond to the grid squares 1o. Therefore, the base 20 has grid squares 10
When placed over the green section or spacing member 67 of each slot
．． 68°69 must be formed so that they are located outside the grid squares 10.

Mutually parallel grooves 76,77 extend through said upper end 74.75 towards a line 17.18 extending through said gap 65.66. These grooves 76 and 77 are connected to the line 17.1.
8 has a cross section sufficient to pass through the grooves 76,77. V476 of one gap 65 is the groove 77 of another gap 66
The lines 3, 5 which define the large grid 4 extend at the same angle to the grid. Usually the grooves 76, 77 are located at different levels, but they can also extend at right angles to each other. In this way, 117.degree. 18 extends exactly into the gap 65, 66 independently of each other, so that the intersection point 19 can be read correctly through the viewing section 86.

The device is further arranged such that the guide 32 extends through the street map 2, for example from a horizontally extending upper edge 33 to a lower edge 34, and limits the street map 2 at an end opposite said upper edge 33. Can be configured.

This guide 32 can, for example, be two rails 35, 36 extending approximately parallel to each other and across the street map 2. These two rails 35.
36 are interconnected by transverse coupling members 37.38;
The connecting member extends substantially parallel to the upper edge 33 and the lower edge 34. The spacing of these rails 35, 36 can correspond to the spacing of two vertical lines 5C or 5b. However, the spacing between the two rails 35,36 can also be chosen differently.

The rails 35, 36 are arranged so as to be movable laterally with respect to the longitudinal direction of the rails along the upper and lower edges 33, 34. These rails can therefore be moved horizontally across the entire street map 2.

The base 20 is arranged on the rails 35, 36 so as to be movable in a direction perpendicular thereto.

Scales 13,14 are provided on this base 20. Lines 17.18 can be moved along these scales 13.14. According to this embodiment of the invention, the street map 2
The base 20 can be positioned relatively accurately thereon. Unwanted movement of the base 20 relative to the street map 2 is effectively prevented. The reason for this is that the guide 32 may unexpectedly slide along the upper edge, or the base 20 may
This is because there is no risk of the device accidentally moving along 36. Base 20 movably mounted on rails 35, 36
can be made according to some of the embodiments described above.

The guide 32 extends vertically or horizontally across the street map 2. Furthermore, this guide 32 can be in the form of a ruler 39 arranged along the corresponding edge 40, 41, 42, 43 with respect to the street map 2. This ruler 39 is made of a transparent material. The base 20 is movably disposed on the ruler. This base 20 can be formed by a frame 25 surrounding an open cavity 28 or by a transparent material.

Both the ruler 39 and the base 20 can be designed as a magnifying glass. In this case, the base 2o has edges 21,
22, 23, 24 can be provided with minute scales 13, 14.

Lines 17, 18 are movably arranged along this fine scale 13,14.

Note that only one line 44 may be provided on the base 20 and this line may extend in the horizontal direction with respect to the vertical direction of the ruler 39. Furthermore, carve a thin line 45 on the ruler 39,
This thin line is made to extend parallel to the longitudinal direction of the constant M39. This thin wire 45 has at least one of its ends a symbol 46 corresponding to the fine scale 14 . ruler 3
9 preferably has a width equal to the width of one square 10. Furthermore, this ruler 39 has fine scales 47 extending in the vertical direction. This fine scale 47 has partial lines 48, and each of these partial lines can be matched with JIJ44 carved into the base 20.

Said ruler 39 can be moved along the vertical edges 41, 43 or the horizontal edges 40, 42, depending on its arrangement, until it corresponds to the symbol 11 or 12 of the large grid 4. These symbols 11, 12 are associated with the details 15 sought in the table (not shown). Next, the base 20 is moved in the vertical direction of the ruler 39 until the line 44 is aligned with the partial line 48 of the scale 47. In this way, the position of the desired detail 15 can be searched along the line 44. This detail is the thin line 45
The symbol 46 is located one level above the table (not shown).
required from.

However, the ruler 39 may not have the thin line 45. In this case, the ruler 39 is simply the base 20.
The ruler has a line 17, 18 over which it can be moved, acting only as a guide for. In this case, the base 20 has, for all practical purposes, the dimensions of a grid grid 10, and its edges 21, 22, 23, as mentioned above,
It has a corresponding scale along 24.

Said edges 40, 41° 42.4 to support the guide 32
A guide edge 49,50 extending along 3 can be provided. These guide edges 49,50 can be adapted to define an open box 51 with a bottom 52 similar to a base with respect to the street map 2. Said bottom 52 is bounded at its two opposite ends by walls 53, 54 which form a substantially right angle and contain it, and on its upper side opposite to said bottom 52 is provided with a guide edge 49.50. Further, in order to reinforce the box 51, lateral walls 55, 56' are provided, and these walls are connected to the walls 53, 5'.
The box 51 may be defined in the horizontal direction with respect to the vertical direction of the box 4. Street map 2 shows walls 53, 54 and side walls 5.
5.56.

Said guide 32 is moved across the street map 2 in guide edges 49,50. For this purpose, the guide 32 has at one of its ends a guide groove 57 extending through the guide edge 49. This guide groove 57 extends in the shape of the letter U over the guide edge 49 and engages with its end 58 located outside the box 51 a retaining member 59 , which retains the box 51 . It is fixed to the wall 54 on the outside and extends in the longitudinal direction of the wall 54. The end portion 58 is attached to the holding member 5
9 and thus prevents the guide edge 49 from sliding out of the guide groove 57.

The guide groove 57 extends on the guide edge 49 and has a pivot hinge 61 in its yoke 60 that extends along the guide edge 49 . The guide 32 is pivotally supported on this pivot hinge 61. The guide 32 can be pivoted away from the street map. The street map 2 can therefore be inserted into or removed from the box 51. Said pivot hinge 61 is arranged to ensure that the guide 32 rests on the street map 2.

In addition, the guide 32 can have a guide groove 62 at its end facing the wall 54.

This groove 62 extends above the guide edge 55. However, the guide 32 can also rest on the guide edge 49 only by means of the guide groove 57.

Street map 2 is inserted into box 51. Usually a folded street map is used, and the required details 1 on top of this street map are
5 is arranged between the wall 53.54 and the side wall 55.56. If necessary, a box is selected for the street map 2 of such size that the entire street map can be placed inside the box 51.

The guide 32 is then pivoted about the pivot hinge 61 to ensure that the guide 32 rests on the street map 2. Next, from a list (not shown), it is determined in which grid square 10 the desired detail 15 is located. - Guide 32 according to the information requested from the list! I! Move it to square 10 of the grid located directly below. The symbol 11 in this square is read from the list. Next, the symbol 12 where the base 20 is located is determined from the list. However, if the thin line 45 extends across the entire ruler 39, it is not necessary to read the symbol 12 for the large grid 4. Instead, the symbol 46 for the cable line 45 and the base 20
It is necessary to find the scale 47 for setting the line 44 engraved in the table from the list. Place the base 20 on the ruler 39 and move it so that it corresponds to the scale 47.
The required rope portion 15 can be found from the intersection of the line 44 and the narrow 1a 45 having 46.

Finally said detail 15, symbol 11.12 and scale 13
．． 14 can be stored in computer 78. The details 15 are stored in this computer 78 by their characteristics, for example their first letter. Details 15 can be called up via keyboard 87 of computer 78. In this way the associated symbols 11.12 and the scale 13
．． It has 14. 111115 appears on screen 88.

Note that the computer 78 has i, II, III lines 89.
Through 90 it can be connected to a servo motor 79 which drives the guide 32. This guide 32 can be arranged movably, for example, on a rack 90 extending over one of the guide edges 49. Said rack 9o is such that its teeth 91 are located in the direction of the transverse coupling member 37 of the guide 32. A pinion 92 is pivotally disposed above the transverse coupling member 37 and is such that its teeth extend into the rack 90. This pinion is driven by a servomotor 79 mounted on the transverse coupling member 37 which moves the guide 32 on the guide edge 49 in accordance with the details 15 called up from the computer 78. Move the guide 32 until it is above the assembly section 15.

Furthermore, the computer 78 is connected by another control line 93 to a drive motor 80 which moves the base 20 along the guide 32. Corresponding to the rope section 15 called up from the computer 78, the base 20 is moved along the guide 32 so that the intersection 19 fixed on the base 20 is connected to this detail 15.
is moved until it is positioned directly above the In this way, through the computer 78 it is not only possible to determine the association of the symbol 11.12 or the scale 13.14 with the rope section 15, but also the i, II generated in the computer 78.
The ill signal makes it possible to locate the position of the rope 15 on the street map 2.

Of course, in this case the exact alignment of the street map with respect to the guide edge 49 cannot be omitted.

The device described above can be used for street maps and maps of any size. It should be noted that this device can also be used to locate the position of other details 15, for example when searching for a detail 15 from a construction drawing whose position has been precisely determined with respect to a section of the drawing.
