SU2533A1 - Location and Direction Indicator - Google Patents

Description

The proposed index is intended to give an opportunity :, to the management of the map, to determine the direction, go find some points in the given locality, or, on the contrary, put the points and directions of the given locality on the map; The proposed index is also intended to give the opportunity to record on the map the places of departure and destination.

The method of determining the location and direction of a vehicle using a map and a compass is not accurate and time consuming. In the known instruments used in geodesic and military affairs, the centers of the direction finder and the compass card lie one above the other, at which the connecting line is simultaneously the axis of rotation of the magnetic needle and the axis of rotation of the direction indicator (alidade). This is a CTIBO device for a non-specialist who wants to quickly and accurately navigate.

using a map is too difficult and difficult to understand. In addition, such tools are too expensive for ordinary, non-special purposes. In the present invention, the scale of the direction finder and the scale of the compass are not placed one above the other, but one on the side of the other, so that each of them is observed separately and therefore the installation of both scales is facilitated. Placed above the graduated scale of the direction finder, the pivoting and mobile directional arrow (alidade) can be clamped in the center of the direction finder scale by means of a screw, on the middle axis of which there is a marker point, installed on the map at the location of the observer or even at the starting point. If the map is positioned from north to south with the aid of a swiveling and fastening compass attached to the subject matter of the invention, sideways from the center of the direction finder

points, at the location of the observer, you can determine the degrees of the direction of the route by means of the direction arrow (alidade equipped with a slit for longitudinal movement, setting the end of the arrow by rotating and moving to the end point. As a result of separation of the scales, the scale of the compass is no longer for direct determine the direction, a ,, mainly, for the correct location of the map or instrument in the direction from north to south. The direction of the path, previously referred to the scale of the compass, the name which also belonged to it (as, for example, the northeast direction), is determined here by the direction finder for each part of the path; as for the scale of the compass, no more counts are made on it and only the north end of the magnetic compass is set to the north end dividing its scale. Since the alidade, the fixed bearing on the mountain and in fixed connection with the compass, which is directed from north to south, accurately determines the direction, then for night use the instrument should be made luminous Only the northern end of the compass arrow, the Nordic division of the compass scale and the groove lying on the longitudinal axis of the alidade. During the trip, the tool also serves to fix important points through the end of the alidade and the spike, since it can be pressed to the map with a spring.

FIG. 1 shows a front view and a partial section of the indicator; FIG. 2 above and in FIG. 3-way following in the form of a broken line.

To the stand /, by means of the clamping screw 3 and the nut 4, is attached on one side of the alidade 2, a. on the other hand, by means of the adjusting screw 6 and the nut 7-compass 5; In addition, a clamp spring 8 is attached below the stand. To count the divisions on the scale of half-rib 9, at any angle of rotation of alidade 2, from north through west to south and northeast-south, in the slot //, which allows for longitudinal movement of the alidade, an arrow 70, rotatable with about the center of the scale half polymba 9 located on the stand. The marked two-way arrow Yu automatically participates in the rotational motion of the alidade, precisely indicating the direction of the latter on the scale of polyhimba. The clamping screw 3 ends on the one hand with a marker tip 12 installed at the location of the observer A, and on the other hand with a fly 13 constituting the sighting line with a slot 15 cut in the handle 14 located at the end of the alidade. At the other end of alidade 2, there is a label 19, for accurate installation at the end point, then a luminous groove 16, for determining the direction at night, and one or more scales of the corresponding country maps for measuring or approximate determination of the distances. When determining the direction with regard to a certain purpose, the subject matter of the invention, instead of pinching it to the map, can be placed on it, and in this case, the tip of the clamping spring 8 serves as an indicator of the observation point, instead of the elevation pin 12. which has a compass, has the shape of a spring 18, which makes it possible to especially firmly pull the compass 5 to the stand 1 by means of the screw b and the nut 7. If, for example, you have to go from point A to O, go to the other points between them, according to FIG. 3, then, with the help of a map, it is already possible to easily create a routing table in advance, so that, at the transition itself, no further definitions of direction will be required and, therefore, the use of potatoes on the way is eliminated. This circumstance becomes especially important in dangerous terrain, which is only crawled, or that are under unsuitable fire.

To compile a route table, the map is located in the north-south direction, the installation tip 12 vim 17 is set at the starting point 7, the mark / 9 at the end of the arrow is set at the intermediate point B, and then counted against the arrow 10-7 on the scale of half-limb degrees route direction. Such a definition of Ipraeleni is made for all intermediate points up to 0 with the following table:

A-B arrow 7 150 °

V -ZH

45 °

Railway 60 ° 90 °

45 ° B -O 90 °

All directions in this example are located in a north-west semicircle (arrow 7) with the exception of the EB direction, which is located in the north-east-south semicircle and therefore determined by the arrow 77. The A-O air line has degrees of direction 1-105 °. Going along the route table should only hold the direction of alidade 2 set at each of the intermediate end points, and the northern end of the magnetic needle should indicate the Nordic division of the compass scale. During the compilation of the table and during the execution of the route AO, no movement of the compass with respect to the semi-rhythm is allowed. Further intermediate points found with the aid of the sighting device facilitate movement in the direction of the intended route.

SUBJECT OF THE PATENT.

1. Indicator of location and direction, characterized by the use of a pivoting and fixed by means of a clamping screw 3, 4 of the alidade 2, located above the semi-rib 9 with a scale and provided with a longitudinal slit 77, the axis of rotation of which the alidade ends with the point 72, which serves to set the pointer to the location the observer on the terrain map, for the orientation of the device, is a compass 5 connected to the polylimimb 9, in which the axis of rotation of the magnetic needle does not coincide with the axis of rotation of the alidade 2, carrying at its end a label that serves as a sight using it to end point B to determine the direction to this point, measured on the divisions of polylimba 9 with the help of a rotating button with an alidade 2 arrow 70.

2. In the said c. paragraph 1, a pointer to the location and direction, supplying the upper end of the clamping screw 3 with the front sight 73, and the end of the alidade 2 with slot 75 serving for sighting on the subject.

3.When marked in p.p. Figures 1 and 2 indicate the location and direction of the use of edges 7 and 77 at both ends of the arrow Yu, in order to use only the semi-rib 9 instead of full limb.

4. In the aforementioned pp 1-3 of the position and direction indicator, supplying the clamping spring 8 with a tip 77, replacing the tip 72 when the device is placed on the card without pinching its clamping spring 8.
