Изобретение относитс к учебным нагл дным пособи м по географии и предназначено дл более эффективного изложени материала и усвоени его учащимис .The invention relates to educational inquiries on geography and is intended to more effectively present the material and its learning by students.

Известно учебное пособие по географии, содержащее глобус, сфера которого имеет отверсти в местах обозначени географических объектов и источник света дл подсветки отверстий 1.A geography textbook containing a globe is known, the sphere of which has openings in places designated by geographic objects and a light source for illuminating openings 1.

Недостатком известного учебного прибора вл етс сложность изготовлени .A disadvantage of the prior art training device is the difficulty of manufacturing.

Целью изобретени вл етс повыщение дидактических возможностей.The aim of the invention is to increase the didactic possibilities.

Это достигаетс тем, что прибор снабжен посто нным магнитом, установленным с возможностью перемещени на внешней дуге глобуса и помещенным внутри сферы двуплечим рычагом с дополнительным посто нным магнитом на конце, образующим с магнитом на внешней дуге глобуса магнитную муфту, при этом рычаг установлен шарнирно в центре глобуса, а источник света помещен на свободном конце рычага.This is achieved by the fact that the device is equipped with a permanent magnet mounted for movement on the outer arc of the globe and a two-arm lever placed inside the sphere with an additional permanent magnet at the end forming a magnetic coupling with the magnet on the outer arc of the globe, while the lever is pivotally mounted globe, and the light source is placed at the free end of the lever.

На фиг. 1 изображен учебный прибор по географии; на фиг. 2 - разрез А-А на фиг. 1.FIG. 1 shows a training device in geography; in fig. 2 shows section A-A in FIG. one.

Учебный прибор по географии содержит глобус 1, сфера которого имеет отверсти 2 в местах обозначени географических точек установленный щарнирно на подставке 3. Внутри сферы установлен источник света 4, размещенный на одном конце рычага 5, шарнирно-закрепленного в рамке 6 с возможностью поворота в любом направлении вокруг центра сферы. На другом конце рычага 5 установлен посто нный магнит 7, образующий магнитную муфту с посто нным магнитом 8, снабженным ручкой 9, установленным на дуге 10 с возможностью продольного перемещени по ней. Сама дуга 10 имеет возможность поворота вокруг оси сферы. Ток к источнику света подведен проводами 11 через опорные оси глобуса. Монтаж внутреннего механизма глобуса может быть осуществлен через люк, выполненный , например, в верхней части сферы.The educational device in geography contains a globe 1, the sphere of which has holes 2 in places designated by geographic points mounted hingedly on a stand 3. Inside the sphere there is a light source 4 placed at one end of the lever 5 pivotally fixed in frame 6 with the possibility of rotation in any direction around the center of the sphere. At the other end of the lever 5, a permanent magnet 7 is installed, forming a magnetic coupling with a permanent magnet 8, equipped with a handle 9 mounted on the arc 10 with the possibility of longitudinal movement along it. The arc 10 itself has the ability to rotate around a sphere axis. The current to the light source is supplied by wires 11 through the reference axes of the globe. Installation of the internal mechanism of the globe can be carried out through a hatch, made, for example, in the upper part of the sphere.

Claims

For the light marking of points on the globe, its sphere is turned by the necessary place to the observers and the electrical circuit of the light source is closed. Moving the magnet 8 along the arc 10 and the arc around the axis of the globe by the handle 9 leads the beam of light to the desired point. In order to better observe the location of the light spot on the inner sphere of the globe, the light spot can be increased by defocusing the optical system by rotating the knob 9 around its axis. In this case, the magnet 8 rotates the magnet 7, which in turn rotates the lever 5 around the axis, moving the light source 4 in the axial direction, thus focusing the light beam. A large spot of light highlights several points on the globe at once. If it is necessary to designate smaller objects, such as cities, the light beam is focused into a smaller light spot. For greater consistency, the light source is powered by a pulsating current. The use of the globe of the proposed design will allow the designation of an unlimited number of both points and entire geographical objects. It can be used both in the presentation of the material by the teacher and in the responses of students. The globe sphere maintains free rotation around its axis, and the necessary optical points can be added to the globe from the outside of the sphere in any quantity and in any place. Claims An educational device in geography containing a globe, the sphere of which has openings in places indicating geographical objects and a light source for illuminating openings, characterized in that, in order to enhance its didactic possibilities, it is equipped with a permanent magnet mounted the globe of the globe and a double-arm lever placed inside the sphere with an additional permanent magnet at the end forming a magnetic coupling with the magnet on the outer arc of the ivio6yca, while the lever is mounted a ball Nirno in the center of the globe, and the light source is placed on the free end of the lever.
