Description

The invention relates to a device for displaying information.

Display devices are known that contain information elements, made in the form of different-color swivel plastids mounted on CLEARINGS) located in the supporting plates, and control electromagnets.

The proposed device differs from the known ones in that it contains permanent magnets mounted on the axis of rotation of the supporting plates made horizontal and associated with control electromagnets, and the rotary plates are made of a non-magnetic material in the shape of a semicircle with a displaced center of gravity.

This allows you to increase speed and increase the reliability of the device.

On h, erge.e shows the proposed device.

It contains information elements made in the form of multicolor swivel plates I from a nonmagnetic material in the shape of a semicircle with an offset center of gravity. The turntables i are mounted on axles x 2 located in the supporting plates 3. The permanent magnets 4 are fixed on the horizontal axis of rotation 5 of the support plates 3 and are connected to the control electromagnets 6 having iron cores 7 which are fixed in the board 8.

Both sides of the turntables I and each half of the support plate 3 have different colors, for example dark and light, and are attached to the support plate 3 by means of axles 2, so that when one part of the support plate overlaps, they have the same color, for example in one position, the pivot plate 1 is lightly on the iHOCTb of the base plate and the light surface of the pivot plate together constitute the bright surface in the form of a full circle. On the colored surfaces of the base plate 3 it is symmetric to the size support line There is one separating spike 9, the color of which coincides with the color of the corresponding part of the surface. One of the separating studs 9 in stable positions is permanently closed by the pivoting plate I. The pivoting plate in all cases forms an angle with the base plate, since it rests on the separating spike. A magnet 4 is attached to the axis of rotation 5. The magnetic axis of the magnet 4 makes an angle with the line of the axis of rotation 5. Behind the magnet 4 there is an electromagnet 6, the iron core 7 of the electromagnet b is made so that the movement of the magnet is limited by a certain arc x) and ensures its fit. In stable positions of the magnet 4, the right side edge of the rotary plate I placed on the support plate 3 forms an angle of 450 with the vertical. The magnet can also be mounted directly on the support plate 3, In this case the magnet 4 mounted at a predetermined distance from the point rotation, rotates in front of the board 8, the iron core 7 of the electromagnet 6 is fixed in the board 8. Thus, within a group of raster elements, for example, with a letter field, elements that serve to indicate information-i of the formation and the control elec- Tromagnets 6 form a self-independent unit. The device works as follows. In one of the stable positions shown in the drawing, the light half of the side of the swivel plate and the light surface of the support plate 3 form together a round light display surface. In this case, the south pole of the magnet 4 is covered by an iron core 7. A rotatable plate placed on the base plate closes the dark separating spike as it rests against it. When electromagnet 6 acquires a south polarity, magnet 4 pushes away from the iron core and turns around the axis of rotation 5 to another part of the iron core 7, also having a polar polarity. In this position, an attractive force arises between the poles, the support plate mounted on the axis of rotation also rotates, raises the center of gravity of the turntable I mounted on the axis x 2, and leads it to an unstable position. An unstable, swiveling plate tends to maintain a stable equilibrium position by shifting down its center of gravity downward, but since the separating spike can only be moved in one direction, the swivel plate rotates around its right side edge like around the axis of rotation and draws to the observer, his dark side, which, in conjunction with the dark side of the base plate, is denoted, suppresses information. After the turn (tilting), the turn plate is again in a stable position, since its center of gravity has returned to its lowest position. When the electromagnet b is excited with reverse polarity, the process is repeated in the opposite direction, and the turntable I is again turned towards the observer with its light side.
