DE7636840U1 - COORDINATE SCALE - Google Patents

Description

Regards; Description of the utility model in accordance with S 3 of the registration provisions

dated June 30, 1968.

1.) Subject:

Coordinates - scale

2.) Area of application of the coordinate scale:

The coordinate scale is a flat precision scale coordinated on transparent dimensionally stable film for mapping Points.

The coordinate scale enables a

" Mapping without drawing auxiliary lines without using auxiliary points ".

The coordinate scale is mainly intended for Production or addition of true-to-scale maps using Coordinates in the surveying and cadastral area. But already in Schools and other technical areas based on linear and plane, right-angled coordinates Mapping work by pupils, technical school students, draftsmen, technicians and engineers apply.

3.) Purpose:

The coordinate measureBtab should do the manual mapping (plot) coordinated points

a) simplify and

b) accelerate.

To a)

State of the art:

For direct mapping of coordinated points, the following are known and in use:

a) drawing and mapping machines as EDP systems and

b) the coordinatograph.

Since here - with the coordinate hatred - only the manual one Mapping is addressed »the EDP - mapping and drawing systems be disregarded.

To b)

The co-ordinator is available as a small co-ordinator or as a larger one Executable as a tabletop device.

Aids and auxiliary devices are known for indirect mapping and on the market:

a.) Kdlliraeter - paper

b) Parallel - glass panel

c) square - glass panel

d) drawing board

e) C ^ uadratnetZBchempel

f) drawing machine and

g) Compass, rule, ruler and drawing triangle.

A coordinate scale on a transparent, dimensionally stable film as a precision scale is not yet on the market. Ground:

Eret in recent years have been measured constant signs. _t -chromatic or repro films developed and offered by specialist companies. These foils have a high degree of piss strength, great dimensional stability, and only very minor changes due to temperature expansion or moisture expansion.

7636840 03/17/77

All drawing, blueprint or repro foils are transparent. ^ J

The foils have meanwhile been tried and tested and are used as a symbol carrier for technical drawings, plans and maps in a wide variety of areas, including as a symbol carrier for official cardboard.

These dimensionally stable foils enable the design and manufacture of the co-ordinate hatred of the

" Mapping without drawing auxiliary lines without using auxiliary points".

5 ») Criticism of the state of the art:

The 'coordinatograph' as a tabletop device was mainly used to plot the uadr-af ^ etzes and the main points. In the administrative district of Trier there is only one device of this kind _o The small coordinateograph in the size of 30 χ * K) cm, made of metal,

one

can already be rational for an office with several technical staff or a technical administration are used.

Both the small co-ordinator and the larger table-top unit are technical Mapping devices (in precision) that are not intended to equip individuals belong.

In today's practice, however, the! Coordinatograph 'loses with the original conception is increasingly important, as the EDP systems are used more and more. There is also the IT equipment for mapping work just as little for personal mapping and drawing equipment belong, for the time being the engineer, technician, draftsman and others only have the use of the known and common auxiliaries & 2 and

are:

aj the rilliaeter - ί-apier too imprecise for different areas, b: the rarallel - glass board only one reading device, c) the jaadrat - glass board only one reading device, d; uie ^ oak panels too imprecise for the map area,

e) the square grid template only for mapping the square grid,

f) the drawing machines are sometimes too imprecise and for certain mapping work not suitable,

g) compasses, measuring rulers, rulers and drawing triangles are the auxiliary devices of the individual for manual mapping.

. J- 4 -

Bas manual mapping in the traditional method is still used today Preparation of «renewal, addition or correction of true-to-scale maps applied·

Our ancestors hit this method over 100 years ago worked and made maps and drawings to scale.

This traditional mapping method for rectangular coordinates requires However

a) Auxiliary lines for mapping auxiliary points and

b) the determination of the new point only at the approval of the auxiliary points.

This traditional mapping method

only leads indirectly to goal I.

In addition, the method is cumbersome because multiple devices are used nuts and several work processes are required

Example ;

For d% s exactly · Mapping a point according to right-angled coordinates in the Gauß-Krüger coordinate system are required:

a) four square net pages as auxiliary lines,

b) four auxiliary points,

c) two additional help lines to determine the location of the new point. A total of six auxiliary lines and four auxiliary points for just one point.

6 ») Task:

The idea of Grunäe lies in the development of the coordinate scale

to refrain from drawing auxiliary lines and mapping auxiliary points

to achieve direct mapping of coordinated points _e

7.) Solution:

The object is achieved in that the auxiliary lines required for mapping are not drawn and displayed on the drawing,

but on the scale I.

763684Θ 17.0177

The representation of the auxiliary lines is dimensionally stable on a transparent Foil possible.

The help lines shown on the coordinate scale - as a grid - make the position of the new point you are looking for visible by counting the X and Y values and allow an exact determination to be made optically of the new point.

Here only the new point has to be marked. Auxiliary lines and auxiliary points can be dispensed with.

8.) Achievable advantages:

Kin coordinate scale on dimensionally stable foil the following working methods:

1) as an overlaying scale (drawing is underlaid) a setting and needling the new point onto the mark carrier. The weaning or needling is done with a compass point or a copying needle

2) as an underlying scale (character carrier is transparent and lies on the? Κ η η f A i na +, en- scale) there is the possibility - without needling through - to map, mark or mark the new point directly.

3) The coordinate hate rod fulfills the same conditions like the foil scale I developed.

k) The coordinate scale also fulfills the function of the known and customary scales.

9.) Description of the coordinate scale:

As models according to S 5 of the registration regulations for utility models this description at:

a coordinate »scale with the scale ratio

1: 250

a coordinate scale with the scale ratio

1 : 500
Each in DIN A k size.

7636840 03/17/77

This fiodelle consist of a transparent film raaßbeständigen and X correspond to the material (film) dsn forth claims. The thickness of the foil is approx. 0.10 mm.

The graphic design (arrangement, division and format) of the two models as coordinate scales is only valid as a draft or suggestion for one of many possibilities.

The drawing accuracy of the models presented does not meet the requirements.

Justification ;

F. a precision scale (here the coordinate scale) cannot be created with conventional zenchen methods and devices. This does not achieve the required accuracy.

For the production of the coordinate scale is the Use of the "scribing process" in automatic character creation or a copper or stone engraving required.

With these well-known precision drawing or duplication processes the required accuracy is to be achieved.

For the registration of the utility model, from my point of view, the presented models fully sufficient, since the f-iikro - film adaptation the absolute accuracy is lost or cannot be maintained »

The achieved accuracy of my models allows a consideration and Assessment or examination of the utility model in connection with the Text of the description completely correct.
