Device for displaying the position of the sun at different times

The invention relates to a device for displaying the location the sun at different times during different parts of the year,

There is a need "the location Her sun at different times of the year indicate and therefore there is a need for this to provide a simple portable device iw disposal,

To: ^- achieve this gave up is _ä indicated fflit Full overlay "invention a device that fflit a base plate of a IFTI Weserit ^a loan planar surface has} on which a Köfflßäß is attached * to UFFL align the surface so j that a marking line on the Grundplätte in Nörd kömmt -Stidrichtung to lie *. Where are provided on the surface more marks _etc. which represent the path of the sun relative to a predetermined location.

A preferred embodiment of an apparatus according to the present invention will be described by way of example in conjunction with the accompanying drawings. In these drawings show:
Fig. 1 is a perspective view of the device for displaying the location of the sonr

Fig. 2 is a plan view of the apparatus according to Fig. 1 and Fig * 3 shows a view of the device of Figure 1 from below * _s

The device 10 consists of a base plate 11 on which a compass 12 is attached and arranged in such a way that when the magnetic needle is aligned with the north pole, the marking line 14 on the base plate 11 is aligned with the actual north pole * The base plate 11 also contains markings 15 in the form of curved lines, which show the path of the sun on certain days of the year, e.g. on the longest day or on the shortest day. The marking lines 16 indicate the location of the sun at certain times during the day, for example at noon and 3 pm. t-

The intersections of the marking lines 15 and 16 show the Position of the sun on certain days of the year and at certain times thereof relative to a point 17 on the base plate 11 at.

The back of the "base plate 11, which is shown in Fig. 3" fulfills the function of the angle _s at which the sun is relative to the ' ^!

The horizon is at the intersection of the marking lines 15 lind 16 the angle can be given j at which the Sons can be found relative to the horizon on certain days and times,

For example could art an intersection, the number "40 °" to be printed, this would indicate j that the sun would be at an angle of 4Ö ^east above the horizon, this angle 40 ° can then be determined by the user of the device by alignment of the Marking line 18 so that it extends horizontally when the base plate 11 is in a vertical position. The user could now look along the line marked "40 °" in order to determine the height of the sun above the horizon.

In the manufacture of the device according to the invention, the positioning of the compass 12 and the marking lines 15 and 16 according to the width and the height error of the square, in which the device is to be used, changed (i.e. it must

ü different for Sydney, Melbourne, London, Tokyo, etc. kon- | be structured).

Claims (2)

1. Device for displaying the position of the sun at different times during different parts of the year on one predetermined location, characterized in that a Koiapass (12) is attached to an essentially flat base plate (11) in this way is that a first scale line (14) on one side of the base plate is aligned in north-south direction when the Compass is set to the magnetic North Pole, with a set of second scale lines, which are essentially on one Arcuate path to extend around a fixed point on one side, as well as a set of third scale lines provided on the same side which extend substantially perpendicular to and intersect the arcuate ones. 2. Apparatus according to claim 1, characterized in that a Sl'ala is attached to the rear of the base plate, the division of which Represents angles from 0 to 90 °. Ill Il 1111 Il I I Il
