Abstract

The invention is intended for use in devices for dividing given angles into an equal number of parts. Expansion of the range of tasks in the polisector, in which four trisector rulers, connected pivotally and connected by transmission links, can be rotated synchronously at the top of a given angle, is achieved by allowing the division of a given angle to be more than three equal parts due to the fact that the transmission links made with three bisector bars and with guides made along a curve with the equation X = SIN (90 ° - ARCSIN Y) -2SIN [1/3 (90 ° - ARCSIN Y]. In this case, the bisector and trisector lines are connected by a crawl set movably on bisector rulers, and by means of connecting rods pivotally connected with trisector rulers and with sliders on bisector rulers with the possibility of moving the sliders along the bisector of the angle between trisector rulers, and mounted on rails connected by connecting rods fixedly connected with the slider on one of the bisector rulers, and by means of sliders connected pivotally and connected with trisector rulers and rods of the slide on a bisector ruler with the possibility of moving the sliders on ravl guides perpendicular bisector line. 1 il.

Description

The invention relates to devices for the name of flat angles and is intended for use of 1l, predominantly, in devices of the name for an equal number of parts.

The goal of the inventor is to expand the range of tasks to be solved by o6et - the liver of the possibility of the name of a given angle by more than three (the number of equal parts)

The polisector contains four trisector lines 1, which are connected by a hinge and are connected by gear units for synchronous rotation at the top 0 for the covert angle of BWW. The tangled links are made with three bisector lines 2, which are also connected to the hinge to rotate as and tri-sector rulers 1 at the vertex 0 of the specified 1L BVO and from N. you | 11 are worn out along a curve with paiuti-s, /; (90 ar i - ,,) 2s urts //;}), lie HiMceT values i i i 1 S O

and are associated with trisector rulers 1 and rods 6 of the slider 4 in the middle position of one of the bisector lines 2 Sliders 7 can be moved using the guides 3 perpendicular to the middle position of one of the bis sector lines 2

During operation, trisector rulers rotate synchronously at the vertex of a given AOB angle, combining the outermost of them with rays of a given AOB angle. Four trisector rulers 1 and dividing the AOB angle into three equal parts, in particular, the AOF, FOG, and QOB angles, and the bisector The second ruler 2 additionally divides the indicated angles into halves, which ensures the division, in general, into six equal parts.

If necessary, for the secret angle AOW is divided (additionally) into two, three, four, and five equal parts or separated from the stasis BOV, 3/5, 2/3, and so on.
