Description

Дл  возможности съемки без присутстви  фотографа у аппарата уже известны приспособлени , служащие дл  спуска затвора через определенное врем  при посредстве заводного часового механизма и звонка дл  подачи сигнала перед съемкой.In order to be able to take pictures without the presence of the photographer, devices are already known that serve to release the shutter after a certain time by means of a clockwork mechanism and a bell to give a signal before shooting.

Предлагаемое приспособление служит дл  той же цели.The proposed fixture serves the same purpose.

На чертеже фиг. 1 показывает разрез часового механизма, а на фиг. 2-схему сцеплени  шестеренок и взаимодействие деталей.In FIG. 1 shows a section of a clock mechanism, and FIG. 2 is a diagram of the coupling of gears and the interaction of parts.

Дл  у снени  работы и устройства предлагаемого приспособлени  предполагаетс , в виде примера, что врем  от момента пуска механизма до начала экспозиции составл ет две минуты, а продолжительность экспозиции (кроме так называемых „моментальных, т. е. тех, на которые можно установить затвор объектива данного фото-аппарата), по выбору фотографа, 1, 2, 3 и 4 сек. Мы остановимс  на первой экспозиции в1 сек. Завод  ключом 26 пружину 8, прибор привод т в состо ние, готовое дл  работы. После наводки фотографического аппарата на намеченный объект на нем укрепл етс  предлагаемое, приспособление. В отверстие спускового рычажка 7 входит штифт 2, держащийс  в нем после посадки своими лапками 3, с которым сцеплен рычажок 4. При нажатии наTo clarify the operation and device of the proposed device, it is assumed, as an example, that the time from the start of the mechanism to the beginning of the exposure is two minutes, and the duration of the exposure (except for so-called "momentary, i.e., on which the lens shutter can be mounted This photo-apparatus), at the choice of the photographer, 1, 2, 3 and 4 seconds. We will stop at the first exposure in 1 sec. Plant key 26 spring 8, the device is brought to a state ready for operation. After aiming the photographic apparatus on the intended object, the proposed fixture is strengthened on it. In the hole of the trigger lever 7 enters the pin 2, holding in it after landing with its paws 3, with which the lever 4 is engaged. When you press the

педальку 5 впадина 6 освобождаетс  от зуба 7 и пружина 8 вращает щестеренку 9. Последн   сцеплена с трибкой 10 шестеренки //, а она, в свою очередь, через трибки 12 к 14 vi их шестеренки 13 и 15, сцеплена с трибкой 16 центробежного регул тора 17 или иного регул тора дл  равномерного спуска пружины 8.the pedal 5, the cavity 6 is released from the tooth 7 and the spring 8 rotates the gear 9. The latter is coupled with the gear 10 tribe, and it, in turn, through the tribes 12 to 14 vi their gears 13 and 15, coupled with the tribe 16 of the centrifugal regulator 17 or another regulator for uniform descent of the spring 8.

Передаточное отношение в данном примере шестеренки 18, сид щей на одной оси с шестеренкой Р, равно 2:1. Следовательно, если шестеренка 18, под действием пружины 8, будет делать два оборота в минуту, то шестеренка 19 сделает в минуту полъоборота или один оборот в 2 минуты. На шестеренке 19 насажено на оси 20 колесико 21 с четырьм  лапками 1, 11, III и f. Дл  перемещени  лапок колесико 21 можно поворачивать на оси только в направлении, показанном на чертеже дугообразной стрелкой. В обратную сторону его не пускает храповой останов (не показанный на чертеже). При рассто нии от оси шестеренки 19 до верхнего предела лапки колесика 21, равного 19,1 мм, диаметр окружности, описываемой концом лапки / при вращении шестеренки 19, будет равен-19,1 X2 38,2 мм, откуда длина этой окружности будет (тгсО, т. е. 3,14X38,,948 мм. Без практической погрешности можно прин тьThe gear ratio in this example, gear 18, sitting on the same axis with gear P, is 2: 1. Therefore, if the gear 18, under the action of the spring 8, will make two revolutions per minute, then the gear 19 will make a half-turn per minute or one revolution per 2 minutes. The gear 19 is mounted on the axis 20 of the wheel 21 with four legs 1, 11, III and f. To move the tabs, the wheel 21 can be rotated on an axis only in the direction shown in the drawing by an arcuate arrow. In the opposite direction it does not allow ratchet stop (not shown in the drawing). At a distance from the axis of gear 19 to the upper limit of the foot of the wheel 21, equal to 19.1 mm, the diameter of the circle described by the end of the foot / when the gear 19 is rotated will be equal to 19.1 X2 38.2 mm, where the length of this circle will be ( hsso, i.e. 3.14X38,, 948 mm. Without practical error, you can accept
