Map protractor with map pointer

The innovation concerns a combined map protractor with a map pointer and a range finder in the form of gripping teeth ■ for a wide range of uses ..

There are probably already plan indicators and range finders in the form of individual devices and also as combined devices become »The combination of protractors and plan indicators is already known»

However, all of these devices are only used to carry out Suitable for measuring tasks on the card ":

The innovation has therefore set itself the task of a material suitable for diverse uses combination device ;, which can be used both for measurement applications on the card as well as in the field to create.

This is achieved by _s that a transparent Vollkreiswink he _ELMESS? which has both the angular division in degrees (360) and in the line dimension (6 ^ 00), preferably in square

Shape is designed, whereby the outer edges are provided with scales and can therefore be used as a scale and also as a map pointer «In addition, part of an edge is provided with a line division the use of the line scale for lateral or height-based distance measurement in the area »One corner of the square is rounded and designed as a range finder with pick-off points. '.-... _

In the drawing is an embodiment of the innovation in View from the front shown ,,: ■ "'-. ■

The device made of a transparent material has has a square shape and has a full-circle angle gauge with two-fold scale division, namely in degrees 1 and in line dimension 2. One corner of the square.-is- strongly rounded and has the finger prongs 3, 'with which distance measurements straight or curved paths can be made on the map, - The mutually perpendicular side edges of the square device wear assigned in pairs

Measuring scales k or »5 ₅ preferably on a scale of 1: 50,000 and 1: 250,000 and can therefore be used as plan pointers or“ coordinate pointers ”because the plan pointer scales 5 only take up less space for the scale 1 s 250,000 On one side of the square there is also a graduated scale 6 which, with the device's eye relief of 50 cm, allows a distance of 10 m to be aimed at a distance of 1 km through a scale interval Terrain »In order to ensure the eye distance of 50 cm quickly and safely, a thread 9" is attached in the center of the device, '.- which-' has a knot at the free end 50 cm away used = In order to accommodate an additional pair of plan pointer scales, an elongated recess 7 is provided in a known manner, which is connected to the. Scale 8 and the vertical scale 8 ^{1 is} provided ο. ■ ".-- ..

Claims (1)

Protection claims: Ι ») Combined map protractor and. Plan pointer from one transparent material, which is characterized by the combination of the following features; a) Full circle protractor in degree (1) and line size (2) Angle division with included compass rose j b) in a square outer shape with at least one ab-. . rounded corner that acted as a range finder with finger prongs. (3) is rounded; c) whereby the perpendicular side edges have graduations and thus serve as plan indicators » - Zc) Combined map protractor and map pointer according to claim Ij, characterized in that a graduated scale (6) is at least partially arranged on one side of the square =. 3o) Combined map protractor and: map pointer according to: Claim .1 and 2, characterized in that in The center of the device, a thread (9) is attached to the display direction and the distance of the eye spacing at visors _o Combined cards protractor and schedule pointer to one or more of the preceding claims characterized gekennzeichnet5 _s that within the device surface at. one or more strip-shaped cutouts (?) additionally one or more plan pointer scales (8 and 8 ') are provided _o A.
