CZ20024241A3 - Riflescope bearing grid for measuring width of objects - Google Patents

Abstract

In the present invention, there is disclosed a telescope bearing grid for measuring width of objects, particularly trees and branches thereof, consisting of a sighting cross and five concentric circles and with division of horizontal axis from 0 to 100, whereby in the center of the bearing grid, there is a line with marking 50. The invention is characterized in that identical divisions 0 through 100 on the horizontal axis are marked with lines (3) of different length perpendicular to the horizontal axis (1) optically forming equilateral triangles (4). The lines (3) marked 0, 10, 20, 30, 40, 50, 60, 70, 80, 90 and 100 pass through v vertexes of the triangles (4), the lower half of the bearing grid has at least one annulus divided by nine semicircles (5) per ten annuli. Preferably the semicircles (5) divide annulus defined by a circle (6) passing through the lines (3) marked 0 and 100 and the circle (6) passing through the lines (3) marked 10 and 90. Vertical axis (2) of the sighting cross is interrupted in a central portion defined by the circle (6) passing through the lines (3) marked 30 and 67. Only some lines (3) are identified by numbers.

Description

Deliberate warp into the scope for measuring the width of objects.

Technical field

The invention relates to an intentional warp into a riflescope for measuring the width of objects.

BACKGROUND OF THE INVENTION.

The distance to the object is measured with the rangefinder. In the riflescope on the deliberate warp, the appropriate number of divisions corresponding to the width of the measured object is precisely read. The deliberate warp is formed by a deliberate cross whose center is circumscribed by five circles, possibly with a division of the horizontal axis from 0 to 100. Normally, this deliberate warp is placed in a riflescope without the possibility of enlarging the monitored object.

The current deliberate warp usually does not have a detailed scale division, exceptionally they have a finer division only on the horizontal axis of the deliberate warp, which does not allow thickness measurements at different angles without turning the riflescope, which is important when measuring the thickness of trees and branches.

SUMMARY OF THE INVENTION

These deficiencies are eliminated by a rifle scope for measuring the width of objects, in particular trees and their branches, consisting of a deliberate cross and five concentric circles, and communicating a horizontal axis from 0 to 100, with a comma at the center of the deliberate warp, the same divisions 0 to 100 on the horizontal axis are marked by unequally long lines 3 perpendicular to the horizontal axis I, which optically form isosceles triangles 4, lines 3 with the designations 0,10, 20, 30, 40, 50, 60, 70, 80, 90 , and 100 pass through the vertices of triangles 4, the lower half of the deliberate warp having at least one annulus divided by nine semicircles 5 into ten annulus.

Preferably the semicircle 5 is divided by an annular circle delimited by a circle 6 passing through lines 3 denoted 0 and 100 and a circle 6 passing through the lines 3 denoted 10 and 90. The vertical axis 2 of the crosshair is in the central part delimited by circle 6 70 interrupted.

Only some commas 3 are numbered.

Preferably, the deliberate warp is located in a rifle scope that has the ability to magnify the measured object in the range of 1.5 to 5 x 20. This riflescope is located on a laser rangefinder. The distance to the object is measured with the rangefinder. The appropriate number of divisions on the deliberate warp is precisely read with the rifle scope. This data is entered into the field computer, where the thickness of the object is calculated using special software and measured distance.

The deliberate warp is housed in a high-impact impact-resistant riflescope tube.

The deliberate warp according to the invention thanks to a detailed and optically divided scale into triangles and plotted circles

- allows very precise measurement of the width of objects

- allows accurate measurement of the width of objects placed in any direction (eg, tree branches) without having to rotate the deliberate warp

- possibility of measurement without the use of mechanical gauges (diameter, band, etc.)

Overview of pictures

Giant. 1 illustrates an intentional warp.

Exemplary embodiment

The deliberate warp shown in Figure 1 is formed on a faceted silicon photoemulsion optical glass.

It consists of a deliberate cross and five concentric circles 6. The horizontal axis i is divided into equal divisions from 0 to 100, with the center line 3 in the deliberate warp. The divisions 0 to 100 on the horizontal axis are indicated by unequally long lines 3 perpendicular to the horizontal axis 1, which optically form isosceles triangles. whose peaks 4 are through Commas that correspond to 0,10,20,30,40,50,60, 70, 80,90, and 100. The deliberate warp contains five concentric circles 6 the lower half of the deliberate warp has an annular delimited by circle 6 passing through the commas 3 with the designations 0 and 100 and the circle 6 passing through the lines X with the designations 10 and 90 divided by nine semicircles 5 into ten annulus. The line thickness of the horizontal axis I and the vertical axis 2 is 0.050 mm. The thickness of the bars 3 and digits is 0.026 mm.

The deliberate warp production is performed on a special machine (computer-controlled pattern generator). The device exposes a pattern to a special glass with a silicon photoemulsion using a xenon lamp, which is entered into the computer. Furthermore, special glass is developed and exposed. The whole process is similar to developing photographs.

Cut optical glass has better properties than glass or plastic pressed materials. In the production of the deliberate warp from materials other than cut glass, distortion occurs at the peripheral parts of the scale, other material has poorer resolution and color distortion (rainbow), and the image of the observed object in the eyepiece may also curl.

Industrial applicability

The deliberate syllabus for riflescopes can be used in forestry.
