CZ300883B6 - 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

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 crosshair and five concentric circles, and with a horizontal axis division of 0 to 100, with a 50 at the center of the crosshair. that the same divisions 0 to 100 on the horizontal axis are marked by unequally long lines (3) perpendicular to the horizontal axis (1), which optically form isosceles triangles (4), lines (3) marked 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100 cross the vertices of the triangles (4), the lower half of the deliberate warp having at least one annulus divided by nine semi-circles (5) into ten annulus.

Preferably, the semi-circle (5) is divided by a circle defined by a circle (6) passing through the lines (3) designated 0 and 100 and a circle (6) passing through the lines (3) designated 10 and 90.

The vertical axis (2) of the reticle is interrupted in the central part delimited by a circle (6) passing through the commas (3) designated 30 and 70.

Only some commas (3) are numbered.

Preferably, the deliberate warp is located in a riflescope, which has the possibility of magnifying the measured object in the range of 1.5 to 5 x 20. This allows the measurement of the width of the distant objects to be measured. This riflescope is located on a laser rangefinder. The distance to the object is measured with a rangefinder. 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 rifle scope.

The deliberate warp according to the invention, thanks to a detailed and optically divided triangle scale and drawn semicircles, allows very precise measurement of the width of objects allows accurate measurement of the width of objects placed in any direction (eg tree branches) (average, band, etc.)

DETAILED DESCRIPTION OF THE INVENTION

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

It consists of a crosshair and five concentric circles 6. The horizontal axis I is divided into equal divisions from 0 to 100, with the center line 3 marked 50 in the center of the reticle. horizontal axis 1, which optically form isosceles triangles, whose apexes 4 pass through lines that correspond to divisions 0, 10,20, 30,40, 50, 60, 70, 80, 90, and 100. The intentional warp contains five concentric circles 6 lower half of the deliberate warp has an annular circle delimited by a circle 6 for25 passing through lines 3 designated 0 and 100 and a circle 6 passing through lines 3 denoted 10 and 90 divided by nine semi-circles 5 into ten circular rings.

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. When producing the deliberate warp from materials other than cut glass, distortion occurs at the edge of the scale, other material has poor resolution, color distortion (rainbow), and the image of the observed object in the eyepiece may also become wavy.

Industrial applicability

The deliberate syllabus for riflescopes can be used in forestry.
