Description

Doppelkegelförmiger Globus. Die Erfindung betrifft einen flach zusammenlegbaren Globus, welcher die Erdkugel in Form eines doppelten Kegels, dessen Höhe gleich dem Durchmesser ist, darstellt in der Weise, wie es in der Kartographie bei der »konischen Projektion« üblich ist.Double conical globe. The invention relates to a foldable flat Globe, which is the terrestrial globe in the form of a double cone, whose height is the same the diameter is represented in the same way as it is in cartography "Conical projection" is common.

Die Zeichnung veranschaulicht ein Ausführungsbeispiel des Erfindungsgegenstandes, und zwar zeigt Abb. a einen Grundriß des zusammengelegten, Abb. z eine Seitenansicht des aufgeklappten Globus.The drawing illustrates an embodiment of the subject matter of the invention, namely Fig. a shows a plan view of the collapsed, Fig. z a side view of the opened globe.

Wie aus Abb. z ersichtlich ist, besteht der Doppelkegelglobus aus zwei Flächensektoren ABC von ungefähr 26o° aus biegsamem Stoff (Papier, Wachstuch, Leder, Zelluloid usw.), die längs ihrer Kreislinie gelenkig zusammengeleimt oder in anderer Weise aneinander befestigt sind. Die 36o° des Äquators entsprechen den a6o° dieser Sektoren, und dementsprechend erfolgt auch die Auftragung der Meridiane. Um aus diesem Sektorenpaar den Doppelkegel zu bilden, zieht man die Sektorenflächen entweder an den Polpunkten P auseinander oder man drückt die beiden äußeren Meridiane AP und CP aneinander. Aus den Sektorenflächen entstehen dann Kegelmäntel, welche die beiden Erdhalbkugeln vorstellen. Das Ganze bildet einen doppelten Kegel, den doppelkegelförmigen Globus.As can be seen in Fig.z, the double-cone globe consists of two area sectors ABC of about 26o ° made of flexible material (paper, oilcloth, leather, celluloid, etc.), which are glued together or otherwise attached to one another along their circular line. The 36o ° of the equator correspond to the a6o ° of these sectors, and the meridians are plotted accordingly. In order to form the double cone from this pair of sectors, either pull the sector surfaces apart at the pole points P or press the two outer meridians AP and CP together. From the sector areas, cone shells emerge, which represent the two hemispheres of the earth. The whole thing forms a double cone, the double-conical globe.

PATENT-ANSPRUCFI: Doppelkegelförmiger Globus, bestehend aus zwei Kegeln, deren Höhe gleich dein Halbmesser ihres gemeinsamen Grundkreises ist, dadurch gekennzeichnet, daß die Kegel aus zwei längs ihrer Kreislinien gelenkig miteinander verbundenen Flächensektoren von ungefähr 26o° gebildet sind, die beim Aneinanderdrücken der äußeren Meridiane oder Auseinanderziehen der Polpunkte den die Erdkugel vorstellenden Doppelkegel ergeben. PATENT-ANSPRUCFI: Double-cone-shaped globe, consisting of two cones, the height of which is equal to the radius of their common base circle, characterized in that the cones are formed from two areas of area of approximately 26o ° connected to one another along their circular lines, which are formed when the outer meridians are pressed together or pulling apart the pole points result in the double cone representing the globe.
