Description
Насто щее приспособление относитс к нагл дным учебным пособи м дл изучени начал геометрии и служит дл демонстрировани свойств углов и угольников.The present adaptation relates to advanced teaching aids for learning the beginnings of geometry and serves to demonstrate the properties of angles and gons.
Приспособление представл ет собою р д пластинок, соединенных между собой шарнирно, наподобие, так называемого, ск.адного метра. Перва и последн пластинки могут замыкатьс посредством специального затвора.The device is a series of plates interconnected pivotally, like the so-called skidding meter. The first and last plates can be closed by means of a special shutter.
На фиг. 1 чертежа изображен общий вид приспособлени ; на фиг. 2 и 2 - замыкание приспособлени при различных положени х конечных пластинок.FIG. 1 shows a general view of the device; in fig. 2 and 2 - the closure of the device at different positions of the end plates.
Приспособление состоит из 12тластин, при чем средн 6 присоединена -к обеим смежным с ней 5 и 7 с одной и той же их стороны, и концы ее лежат в одной плоскости (фиг. 1). Этим облегчаетс построение симметричАх фигур. Дл прочного смыкани концов первой и последней пластин в их различных положени х приспособление снабжено затвором,, состо щим из поворотно укрепленной на первой пластине накидной петли / и шпенька 2 с винтом 5, укрепленного на последней пластине. Способ замыкани сен из .прилагаемого чертежа (фиг, 2 и 2).The device consists of 12 plates, with the average 6 being attached to both adjacent 5 and 7 on the same side of it, and its ends lie in the same plane (Fig. 1). This facilitates the construction of symmetrical shapes. In order to firmly close the ends of the first and last plates in their various positions, the fixture is provided with a shutter, consisting of a cap loop / which is pivotally fixed on the first plate, and a peg 2 with screw 5, fixed on the last plate. The method of closing the screen from the attached drawing (FIGS. 2 and 2).
