Description
Предлагаемое приспособление предназначаетс дл прижимани чертежной бумаги к доске без употреблени кнопок.The proposed fixture is intended to press the drawing paper to the board without using buttons.
На чертеже - фиг. 1 изображаем; вертикальный разрез приспособлени ; фиг. 2- вид его снизу; фиг. 3 -деталь приспособлени .In the drawing, FIG. 1 we depict; vertical section of the device; FIG. 2- its bottom view; FIG. 3-part fixture.
Приспособление состоит из двух концентрических цилиндров 5 и б с ход щим между ними поршнем 8, управл 1емым при помощи хтержн 1, оканчивающегос крестовой зубчатой рейкой 11. Эта рейка сцепл етс с заклинчгнными на своих ос х шестерн ми 9,10,12 и 13, привод щими во вращение барабаны, на которые наматываютс цепи 7,. соединенные другим концом с поршнем 8.The fixture consists of two concentric cylinders 5 and b with a piston 8 running between them, controlled by means of x 1, ending with a cross rack 11. This bar engages gears 9, 10, 12 and 13 on its axles, driving drums on which chains 7 are wound. connected to the other end with the piston 8.
К нижней приспособлени на поворотном стержне 18 прикреплена пластина 22, через которую пропущен штифт 20, несущий на своем конце лружинный прижим 19. Между пластиной 22 и прижимом 19 помещена рружина 21, служаща дл прижимани чертежной бумаги к столу. Когда приспособление установлено йа чертежной доске иприжато к ней атмосферным давлением, поворачивают стержень 18, придержива пальцами пружину 21 до тех пор, пока прижим 19 не расположитс над бумагой . При освобождении, пружины прижим 19 под ее давлением достаточна крепко будет придерживать чертежнуюбумагу на доске.A plate 22 is attached to the bottom fixture on the rotatable rod 18, through which a pin 20 is passed, carrying a spring-loaded clamp 19 at its end. A spring 21 is placed between the plate 22 and the clamp 19, which serves to press the drawing paper to the table. When the device is installed on the drawing board and pressed to it by atmospheric pressure, the rod 18 is turned, holding the spring 21 with your fingers until the clamp 19 is positioned above the paper. When released, the spring clamp 19 under its pressure will firmly hold the drawing paper on the board firmly enough.
Предмет изобретени .The subject matter of the invention.
1.Приспособление дл прижИмани чертежной бумаги к доске, отличающеес .1. A device for pressing drawing paper to the board, different.
.применением пустотелой стойки, удерживаемой на доске разрежением во внутренней ее полости воздуха и несущей пружинный дл бумаги прижим 19.by using a hollow stand held on the board by a vacuum in its internal air cavity and a pressure-bearing spring 19 for the paper.
2.Форма выполнени охарактеризованного в п. 1 прибора, отличающа с тем, что стойка выполнена в виде коль-i цевого цилиндра с поршнем 8, дл перемещени коего предназначены цепи,, наматыв мые на барабаны, вращаемые от заклиненных на их ос х шестерен 9, 10, 12 и 13, получающих в свой очередь вращение от крестовой рейки 112. The form of the device described in paragraph 1, characterized in that the rack is made in the form of a ring cylinder with a piston 8, for which chains are intended to be wound onto drums rotated from gears wedged on their axes 9 , 10, 12 and 13, receiving in turn the rotation from the cross rail 11
