Description

Wynalazek niniejszy dotyczy przyrzadu do uruchomianiaj klapki filmu w aparatach kinematograficznych i polega na zwiazaniu drzwiczek aparatu z klapka filmu, co auto¬ matycznie doprowadza klapke filmu do po¬ lozenia zacisniecia lub rozluznienia przy zamykaniu lub otwieraniu drzwiczek apa¬ ratu.Wedlug jednego ze sposobów wykona¬ nia wynalazku na drzwiczki aparatu umie¬ szcza sie czesc, która przy zalmykaniu drzwiczek naciska na klapke filmu i wpro¬ wadza ja do jej gniazda; klapka ta zostaje natomiast zwolniona otworzeniem drzwi¬ czek aparatu.Na zalaczonym rysunku, podanym tytu¬ lem przykladu, fig. 1 wyobraza widok bocz¬ ny klapki z pominieciem drzwiczek aparatu, fig. 2 i 3 — przekroje prostopadle do osi drzwiczek aparatu, przedstawiajace klapke filmu i drzwitzki aparatu, odpowiednio w pozycjach otwartej i zamknietej.Klapka 1 filmu obraca sie na osi 2 w ka¬ dlubie aparatu i posiada ramke 3 przyci¬ skajaca film 10 do kanalu 5 zapomoca spre¬ zyny 11 podpartej drazkiem 12 umocowa¬ nym w klapie /. Drzwiczki 6 aparatu kine¬ matograficznego obracaja sie na zawiasach 7 w kadlubie aparatu i zaopatrzone sa w prostopadla stopke 8 takiej dlugosci* aby ta przy zatrzasnieciu drzwiczek 6 zetknelasie ze stopka 4 klapki 1 i wywolala w ten sposób na nia cisnienie.Przyrzad dziala w sposób nastepujacy.Gdy drzwiczki 6 sa otwarte, klapka / znaj¬ duje sie wewnatrz gniazda 5 (fig. 2). Prze¬ ciwnie, po zatrzasnieciu drzwiczek 6 stopka 8 wywfera cisnienie na klapke 1 za posred¬ nictwem stopki 4, która zimuiszai do wpro¬ wadzenia filmu 10 do gniazda 5. Otwarcie drzwiczek zwalnia automatycznie klapke 1 wskutek nacfeku sprezyny 11 ramki 3.Rzecz prosta, ze do uskutecznienia tego oswobodlzenia, mozna zastosowac odpowied¬ nie polaczenie miedzy klapka 1 i stopka 8.Udoskonalenie niniejsze znacznie upra¬ szcza czynnosci ladowania i wyladowywa¬ nia aparatu. W rzeczy samej do umie¬ szczania na miejscu filmu, po umieszczeniu puszki z filmem w aparacie i obraczki filmu w klapie 1 wystarcza zamknac drzwiczki.Mozna naturalnie wprowadzic róznfc zmiany w budowie przyrzadu powyzej opi¬ sanego, nie wychodzac poza ramy wynar lazku. PLThe present invention relates to an apparatus for activating the film flap in cinematographic apparatus and consists in binding the camera door to the film flap, which automatically brings the film flap to a clamped or loosening position when closing or opening the camera door. According to the invention, a part is placed on the door of the apparatus, which, when the door is closed, presses on the flap of the film and guides it into its seat; the flap is released by opening the door of the apparatus. In the accompanying drawing, given by way of example, Fig. 1 shows a side view of the flap, omitting the apparatus door, Figs. 2 and 3 - sections perpendicular to the axis of the apparatus door, showing the flap The film flap 1 of the film rotates on axis 2 in each camera club and has a frame 3 that presses the film 10 to the channel 5 by means of a spring 11 supported by a rod 12 fixed in the flap /. The door 6 of the cinematographic apparatus rotates on hinges 7 in the apparatus body and is provided with a perpendicular foot 8 of such a length * that when the door 6 is closed, it contacts the foot 4 of the flap 1 and thus exerts pressure on it. .When door 6 is open, the flap / is inside slot 5 (fig. 2). On the contrary, when the door 6 is closed, the foot 8 will exert pressure on the flap 1 through the foot 4, which will cool down until the film 10 is inserted into the slot 5. Opening the door automatically releases the flap 1 due to the puncture of the spring 11 of the frame 3. A simple thing, that to effect this liberation, an appropriate connection can be made between the flap 1 and the foot 8. This improvement greatly simplifies the loading and unloading operations of the apparatus. In fact, for placing the film in place, after placing the film can in the camera and the film ring in the flap 1, it is sufficient to close the door. One can naturally make a variety of changes in the structure of the device described above without going beyond the framework of the bench. PL
