Description

Device for location determination. The invention relates to a device for determining the location of a vehicle, aircraft, ship, motor vehicle o. The like., Distance traveled and the place where the vehicle is while the journey indicated by a pen on a drawing sheet or map and is recorded. It is known in such devices, the direction of movement the pen by a compass and its speed of movement to control a moving part of the vehicle electromagnetically.

The known devices of this type are mostly due to their extensive Drive devices so large that they take up a lot of space and therefore in one smaller vehicles are difficult to accommodate.

The invention eliminates this disadvantage in that the carrier of the Two magnet groups consisting of several electromagnets arranged are. One of these groups of magnets, the directional magnets, is replaced by one on the compass arranged contact device energizes and moves a metal disc on the The axis of rotation of the pen is arranged. The other group of magnets. the moving magnets, is through a contact device connected to the movement device of the vehicle excites and acts on a metal ball arranged at the foot of the pen holder, to move the pen on its surface.

According to the invention, this base is a magnetized steel plate. Furthermore, according to the invention on the pen holder is a control device for arranged in the direction of pen movement. The invention also includes a particularly suitable contact device for the compass.

The drawing shows an embodiment of the subject matter of the invention. namely Fig. i a circuit diagram of the system, Fig. 2 the overall arrangement of the Device, fig .; the pen holder and the parts attached to it in Side view, Fig..l a plan view of the pen carrier, Fig. J5 the contact device on the compass, Fig. 6 to 9 details of the pen holder.

The entire system (Fig. 2) consists of a recorder I, a compass 11, a contact device III attached to the machine for the movement of the vehicle concerned, and a switch box IV. In addition, a battery V is required to power the system.

The writer I, which is movable on its base, is electrically connected connected to the compass 1I and the contact device III. This makes it electromagnetic brought in the direction taken by the vehicle and corresponding to the vehicle movement moved under the map. So the writer performs the same movements the map as they are carried out from the vehicle to earth. Deviation as well Air or water currents are to be determined prior to setting off the vehicle according to the following: fluids (Weather maps, etc.) to be taken into account when setting the recorder.

The pen 1 is composed of two main parts. These are a tripod i2 and a vertical '' skins ii (Fig. 3). The tripod 12 is open three steel rollers 13 movable (Fig. 6 and 9). It is equipped with a magnet arrangement 3, 5 and 6 (Fig. 9) and at the upper end with the graduation i (Fig. 3 and 6).

The vertical shaft ii is in the tripod 12 in two bearings (Fig. 6) rotatable. Opposite the magnet 3, it carries a wedged iron disk 4 (Fig. 3 and 8) and ends at the lower end in a fork in which a steel roller io is rotatable. A second magnet arrangement 7, 8, 9 (Fig. 8) attached to the fork, namely the: magnets 8 and 9 are fixed, the magnet 7 attached to a rod-shaped carrier 7a which can be displaced between the magnets 8 and 9. At the top of the t '. all ii are located-four slip rings 21 made by brushing with the cable 22 (Fig.;, and 6) are connected. The tip of @ # elle i i is running in a thread (Fig.8) on which the hood with the magnet 16 (Fig.7), the pen 17, the helical spring 18 and the fixed pointer 2 are screwed on will.

The mode of operation of the two accommodated in the main parts of the scribe Magnet arrangements is the following for the magnet arrangement, -, 5, 6 in the contact device A circuit is closed at the compass 1I (Fig. 2), so the magnet is excited. He presses against the iron disk .I. But at the same time it is also through the same Current shortage of magnet 5 or 6 energized, whereby the approach "" '(Fig. 9) attracted and so that the magnet 3 is moved laterally. Because closing the circuit only for a brief moment and then the magnet;, always in its old one When the position returns, a rotating movement is achieved on the iron disk 4.. In The magnet arrangement 7, 8 and 9 on the steel roller also works in the same way ok

The writer I moves in a box 1q. (Fig.2) on one magnetizable steel plate 15 (Fig. 3). The magnetization is supposed to slip exclude the recorder in the event of vibrations, including the resilient suspension provided alone would not be enough. The lid of the box 1.1 consists of a pane of glass 20. Under this is the map with the printed side up. The distance covered is shown on the bottom of the map. So that the drawing is clearly visible, there is either a card on a translucent one Paper or a light bulb must be turned on in the box.

In order to be able to set the recorder correctly before setting off the vehicle, taking into account the deviations, air and water currents, etc., the division i (Fig. 3 and 6) is provided with a graduation of 360 'on the upper part of the tripod , over which the pointer 2 (fig. 1 and 7), which forms a whole with the m elle ii, moves. h he division i retains the same position in relation to the vehicle as the fixed division of the compass. The pointer 2 always shows the direction of travel.

The magnet 16 (Fig. 7) has the task of adjusting the recorder Pick up the pen 17 from the card under the point of departure of the vehicle. The excitement of the Magnet 16 happens here from the switch box IV from, from where the recruitment of the clerk through a second contact of the Switching lines of the compass II and the contact device III takes place.

The movements of the compass are transmitted to the recorder in such a way that a circuit is closed each time the compass is turned to the left or right. As a result, the electromagnet 3 presses against the round disk 4 attached to the shaft ii. At the same time, the rod-shaped extension 3 'is attracted by the same current from the electromagnet 5 or 6, so that the magnet arrangement exerts a rotating movement on the disk 4. This movement corresponds to that of the compass, but in the opposite sense, i.e. the same as the direction of the vehicle to the earth.

The locomotion of the vehicle is made by closing a circuit in the contact device III transferred to the recorder. Here the presses itself Electromagnet 7 on the large steel roller io. At the same time, depending on the or backward movement of the vehicle, from the electromagnet 8 or 9 the rod-shaped Approach 7a tightened. This produces a rotary movement of the steel roller io. As with the first magnet arrangement, the current is only momentary closed. The magnet 7 then returns with its rod-shaped support 7 ″ each time back to its original position. The contact device is mechanical with the machine for moving the vehicle or a speedometer connected by an adjustable gear box. This increases the speed in transferred to the recorder on a reduced scale. Air or water currents in the direction of the vehicle are controlled by increasing or decreasing the speed of the recorder takes into account what can easily be done in the gear box.

The contact device on the compass (Fig. 5) consists of the switching lever 23, which is rotatably arranged in point 2.4, the two mercury contacts 26, the two leaf springs 25 and the graduation plates 29 attached to the edge of the movable graduation 28. The fixed graduation of the compass is denoted by 24. 30 is the supply cable.

The power supply to the compass takes place in the `` quiet '' state that the gearshift lever 23 with each left or right rotation of the movable division 28 through the degree plates 29 is brought into contact with the right or left mercury contact. By the two leaf springs 25 become the shift lever each time after the circuit is closed brought back to its old position. I- he mercury contacts 26 exist each from a small vessel filled with mercury, the one on the side a small one Has opening through which the approach of the switching lever 23 can touch the mercury.
