Description

- .t . Изобретение относитс  к техничес кой физике, а конкретнее,к затворамдиафрагмс1М дл  фотоаппаратов, где отсекатели затвора выполн ет одновремённЬ и роль диафрагмы объектива ИзЦестен центральный затвЬр, со,-, держащий два приводных кольца, установленных концентрмчно со смещением относительно друг друга. Недостатком этого устройства  вл  етс  низкое быстродействие эатвора. Известен затвор - диафра гма, соде.о жащий корпус, кольцо установки днафраг№1 , приводные кольца, лепестки, двигатель и привод, включгиощий дв.ухплечий рычаг, св занный с приводными кольцами. Недостатками этого устройства  вл ютс  сложность конструкции и низко быстродействие. Цельизобретени  - увеличение быстродействи  и повышение точности его работы. Указанна  цель достигаетс  тем, Что привод выполнен в виде рычага, одним плечом взаимодействующего с двухплечим рычагом, а другим - с двигателем и через закрепленную на нем ось - с пазом ко. установки диафрагмы. На фиг. 1 приведена конструкци  предлагаемого затвора-диафрагмы; на фиг. 2 - один из вариантов кинематической св зи привода с двигателем . Зат.вор состоит из корпусной детали 1 с пр молинейным пазом 2; лепестков 3, приводных колец 4 и 5 с пальцами 6 - 9;.. двухплечего рычага 10 с пальцем 11, укрепленного на оси 12 и служащего дл  сообщени  приводным кольцам 4 и 5 разнонаправленного движ-ени ; рычага 13 с подвижной осью 14 и пазами 15 и 16; кольца 17 ручной установки диафрагмы с пазом 18; Еилчага 19 с пальцем 20, укрепленного на оси 21;  кор  22; электромагнита 23. В другсэм варианте кинематическа  св зь привода с двигателем включает, эксцентрик 24 с пальцем 20., приводимый во вращение пружиной 25, шестерню 26/ св занную с механизмом взвода , и спусковым , крючком 27. Устройство работает следующим образом. С помощью кольца 17 устанавливаетс  диафрагма, которай необходима по услови м съемки и(будет отработана . При повороте кольца 17 пазом .- .t. The invention relates to technical physics, and more specifically, to shutter diaphragms 1M for cameras, where shutter cutters perform simultaneously and the role of the lens diaphragm IzCisten central shutter, with, holding two driving rings mounted concentrically offset from each other. A disadvantage of this device is the low speed of the remote control. The known closure is the diaphragm, which contains the housing, the mounting ring No. 1, the driving rings, the petals, the engine and the drive, and the double-arm lever connected to the driving rings. The disadvantages of this device are design complexity and low speed. The purpose of the invention is to increase speed and increase the accuracy of its work. This goal is achieved by the fact that the drive is made in the form of a lever, one arm interacting with a double-arm lever, and the other with a motor and through an axis fixed to it with a groove to. install aperture. FIG. 1 shows the design of the proposed shutter-diaphragm; in fig. 2 is one of the variants of the kinematic connection of the drive with the engine. The gate consists of a body part 1 with a straight groove 2; petals 3, drive rings 4 and 5 with fingers 6-9; .. a double-arm lever 10 with a finger 11 fixed on the axis 12 and used to communicate the driving rings 4 and 5 of multi-directional movement; lever 13 with a movable axis 14 and grooves 15 and 16; rings 17 manual installation of the diaphragm with a groove 18; Eilchaga 19 with a finger 20, mounted on the axis 21; cor 22; electromagnet 23. In another version of the kinematic connection of the drive with the engine includes an eccentric 24 with a finger 20., driven in rotation by the spring 25, gear 26 / associated with the cocking mechanism, and the trigger hook 27. The device operates as follows. With the aid of ring 17, a diaphragm is established, which is necessary according to the shooting conditions and (it will be worked out. When the ring is turned by 17-groove.
