Description

(54) ПРИСПОСОБЛЕНИЕ ДЛЯ ДЕЖНЙЯ ПРЯМЫХ НА ПРОПОРЦИОНАЛЬНЫЕ ОТРЕЗКИ(54) FITTINGS FOR DIGGING DIRECT ON PROPORTIONAL CUTS

Изобретение относитс  к вспомогательным принадлежност м дл  письма и черчени  и мохсет быть использовано например, при построении графиков и таблиц. По основному авт.св. № 656882 известно приспособление дл  делени  пр мых на пропорциональные отрезки, выполненное в виде пластины, на поверхности которой нанесены риски, образующие пр моугольный треугольник катет которого разделен на равные отрезки, соединенные рисками с верши ной противолежащего угла, и риски, образующие второй треугольник, аналогичный первому, построенный на его гипотенузе и образующий с первым тре угольником пр моугольник, при этом вдоль всех рисок выполнены прорези pj Однако известное приспособление не дает возможности одновременного делени  взаимно перпендикул рных пр мых при изменении масштаба по одной из осей. Цель изобретени  - расширение диапазона решаемых задач. Ш  достижени  этой цели пластина состоит иэ двух подвижио соединенный по гипотенузе частей. На фиг.1 схематически показано приспособле1ше, общий вид} на фнг.2разрез А-А на фиг.. Приспособление шлполнеио в виде пластины, состо щей из частей 1 и 2, соединенных между собой подвижно с помощью соединени  типа ласточкин хвост. На пластины нанесены ipeугольники ВСЕ и ЁСО их стороны BE и ВО перпендикул рны и разделены на. равные или пропорциональные части. Вдоль рисок, соедин гащпс точки делени  с вершине С, общей дл  обоих треугольников, выполнены прорези 3, обозначенные цифрами по,пор дку номеров . Лини  4, по которой соедин ютс  пластины, параллельна начальной прорези 5, совпадающей с общей гипотенуThe invention relates to writing accessories and drawing and mohset be used, for example, in the construction of graphs and tables. According to the main auth. No. 656882 is known a device for dividing straight into proportional segments, made in the form of a plate, on the surfaces of which there are risks, forming a right triangle, the leg of which is divided into equal segments, connected by risks with the apex of the opposite angle, and the risks forming the second triangle, similar to the first one, built on its hypotenuse and forming a rectangle with the first triangle, at the same time pj slots are made along all scratches. However, the known adaptation does not allow simultaneous ELENI mutually perpendicular straight when changing the scale of one of the axes. The purpose of the invention is to expand the range of tasks. To achieve this goal, the plate consists of two motions connected by the hypotenuse of parts. Fig. 1 schematically shows an adaptation, a general view of Fig. 2, section A-A in Fig. A device in the form of a plate consisting of parts 1 and 2, which are interconnected movably by means of a dovetail connection. On the plates are ipegons ALL and YOSO, their sides BE and IN are perpendicular and divided into. equal or proportional parts. Along the line, connected to the point of dividing from the vertex C, common to both triangles, slots 3 are made, indicated by numbers in order of numbers. Line 4, along which the plates are connected, parallel to the initial slot 5, coinciding with the common hypothesis
