Description
Предметом изобретени вл етс прибор дл вычерчивани дуг окружностей больших радиусов, в котором применена гибка линейка, поставленна на ребро и изгибаема в дугу необходимого радиуса путем сближени ее концов. Линейка изготовл етс из пружин щего материала, нанример , стали, а дл изгибани концы ее шарнирно присоединены к ст жке-хорде, длину которой можно измен ть.The subject of the invention is a device for drawing arcs of circles of large radii, in which a flexible ruler is applied, set on an edge and bent into an arc of the required radius by bringing its ends together. The ruler is made of spring material, nanorimer, steel, and for bending its ends are pivotally attached to a tie-chord, the length of which can be changed.
Особенностью предлагаемого прибора вл етс то, что примененна в нем линейка имеет разные высоты по длине, а верхнее ребро ее, ограничивающее эти высоты, выполнено по синусоиде. Така форма линейки при сближении ее концов обеспечивает изгиб, наиболее приближающийс к окружности.A feature of the proposed instrument is that the ruler used in it has different heights in length, and its upper edge, limiting these heights, is made in a sinusoidal fashion. This shape of the ruler, when approaching its ends, provides a bend that is closest to the circumference.
На фиг. 1 показан вид прибора сверху; на фиг. 2 - вид по стрелке А на фиг. 1; на фиг. 3 - вид по стрелке Б на фиг. 1; на фиг. 4, 5 и 6 - вид стопорного механизма в двух проекци х и в разрезе; на фиг. 7 прибор показан в рабочем поло кении с линейкой, изогнутой по дуге радиуса.FIG. 1 shows a top view of the device; in fig. 2 is a view along arrow A in FIG. one; in fig. 3 is a view along arrow B in FIG. one; in fig. 4, 5 and 6 - view of the locking mechanism in two projections and in section; in fig. 7 the device is shown in the working position with a ruler bent along an arc of radius.
Линейка /, изготовленна из стальной ленты или другого эластичного и пружин щего материала, при помощи крониттейнов 2 присоединенаThe ruler /, made of steel tape or other elastic and spring-loaded material, is attached with the help of 2 kontins
к ст жке-хорде -3. Линейка присоединена к кронщтейнам неразъемным соединением, а кронщтейны присоединены к ст жке-хорде при помощи щарниров 4.to the hard-chord -3. The ruler is attached to the brackets by a one-piece connection, and the brackets are attached to the tie-chord using joints 4.
Нижн кромка 5 линейки пр ма , а верхн кромка 6, ограничивающа разные по длине липейки высоты, вы.полнсна по синусоиде с целью изгиба линейки при сближении ее концов по дугам окружности.The lower edge 5 of the ruler is straight, and the upper edge 6, which bounds different heights along the length of the sticky lip, is sinusoidally full in order to bend the ruler as its ends draw together along circular arcs.
Ст жка-.хорда 3. с помощью которой сближаютс концы ,1инейки, состоит из трубки 7 и вход щего в нее одним концом стержн 8. Изменение длины ст лски-хорды достигаетс вдвиганием стер/йн 8 к трубку 7 и выдвиганием его. На стержне 8 сделаны зубцы 9, а на трубке 7 укреплена шарнирно подпружиненна собачка 10 с упором // дл пальца руки.String-hord 3. with which the ends, 1 lines, come together, consist of a tube 7 and a rod 8 entering it at one end. A change in the length of the stitch chord is achieved by sliding the ster / yn 8 to the tube 7 and pushing it out. Teeth 9 are made on the rod 8, and a hingedly spring-loaded dog 10 with an emphasis // for the finger is reinforced on the tube 7.
Дл устаповки прибора на заданный радиус окружности на трубке 7 нанесены делени и сделана прорезь J2. через которую наружу выходит стрелка-указатель 13. пр1п репленна к концу стержн 8, наход н егос внутри трубки.To install the device for a given radius of a circle, the tube 7 has divisions made and a slot J2 is made. through which the arrow-pointer 13 comes out. The pr1p is replenished to the end of the rod 8, which is located inside the tube.
