Description

Die Erfindung betrifft eine Deckelverriegelung für Laufbildgeräte, insbesondere Schmalfilmkameras. Bei der Konstruktion solcher Kameras ist man bestrebt, zur Gewichtsersparnis und bequemeren Handhabung die Größe des Kameragehäuses auf ein Mindestmaß zu beschränken. Es muß daher im Innern des Gehäuses mit äußerst engen Raumverhältnissen gerechnet werden. Bei den seitherigen Nl'erriegelungseinrichtungen. mit beweglichen Verriegelungsgliedern am einen Gehäuseteil und festen Verriegelungsgliedern am andern ist die Unterbringung vor allem der festen Glieder schwierig, da der verfügbare Raum im Gehäuse durch die Filmspulen, die Filmschleifen, die Filmbahn und die Antriebsteile voll und ganz in Anspruch gevommen ist und nicht noch durch das Gehäuse durchsetzende Riegelbolzen oder die Gehäusewand nach innen verstärkende Verriegelungsnocken weiter verengt werden darf. Auch ergeben sich für die Verriegelungsglieder noch besondere Bearbeitungsflächen am Gehäuse, die für eine einwandfreie Verriegelung genau und sorgfältig ausgeführt sein müssen.The invention relates to a cover lock for motion picture devices, especially cine cameras. In the construction of such cameras, the aim is to the size of the camera housing for weight saving and convenient handling to restrict a minimum. It must therefore be extremely tight inside the housing Spatial conditions are expected. With the previous locking devices. with movable locking members on one housing part and fixed locking members on the other hand, it is difficult to accommodate, especially the fixed limbs, since the one available Space in the housing through the film reels, film loops, film web and drive parts is fully taken up and not yet penetrating through the housing Locking bolts or locking cams reinforcing the housing wall inwards may be narrowed. There are also special ones for the locking members Machining surfaces on the housing that are accurate and required for proper locking must be carried out carefully.

Die Erfindung vermeidet in Abkehr vom Bekannten besondere feste Verriegelungsglieder und schlägt statt dessen die entsprechend ausgebildeten Enden der Filmspulenachsen als feste Gegenglieder für die Verriegelung vor. Vorteilhaft ist diese Maßnahme in Verbindung mit solchen bekannten Deckeiverriegelungen durchzuführen, bei denen die beweglichen Verriegelungsglieder durch einen gemeinsamen Griff betätigt werden.In a departure from the known, the invention avoids special fixed locking members and instead strikes the correspondingly formed ends of the film reel axles as fixed counter links for the lock. This measure is advantageous to perform in connection with such known ceiling locks, in which the movable locking members are operated by a common handle.

Im folgenden sei ein Ausführungsbeispiel der Erfindung an Hand der Zeichnung beschrieben. Es stellt dar Fig. i die Ansicht des Gehäusedeckels von der Innenseite aus, Fig. 2 einen Schnitt durch Deckel und Gehäuse nach dem Linienzug 11-II der Fig. i.In the following an embodiment of the invention is based on the Drawing described. It represents Fig. I the view of the housing cover of the Inside from, Fig. 2 shows a section through the cover and housing according to the line 11-II of FIG.

Im abriehmbaren Gehäusedeckel i führen auf die runden Vertiefungen 2 zwei Nuten 3 zu, die in ihrer Lage der Anordnung der Filmspulenachsen im Gehäuse entsprechen. In diesen Führungsnuten3 sind die beiden Riegel,4-in ihrer Längsrichtung verschiebbar. Sie sind an ihren an die Vertiefungen 2 heratireichenden Enden 5 gabelförmig ausgeschnitten. An ihren anderen Enden tragen sie eingenietete Steuernocken 6, mit denen sie in die Kurven 7 einer Kurvenscheibe 8 eingreifen. Diese Kurvenscheibe sitzt mittels einer Zweiflachverbindung fest auf dem Schaft 9 des mit einem umlegbaren Bügel i o versehenen Verriegelungsknopf es i i, welcher etwa auf halber Höhe des Gehäusedeckels i drehbar gelagert ist. Die Kurvenscheibe 8 wird durch ein kreisrundes Abschlußblech 12 überdeckt. Das Ganze wird durch eine Schraube 13 zusammengehalten. Die gabelförmigen Enden 5 der Riegel 4 sind durch runde, mit einer Mittelbohrung versehene Scheiben 14 gegen Heraustreten aus den NUtell 2 gesichert. In Fig. i sind der Deutlichkeit halber Abschlußblech 12, Schraube 13 und Scheiben 14 -,veggelassen.In the removable housing cover i, two grooves 3 lead to the round recesses 2, the position of which corresponds to the arrangement of the film reel axes in the housing. In these guide grooves 3, the two latches 4, 4 are displaceable in their longitudinal direction. They are cut out fork-shaped at their ends 5 reaching toward the depressions 2. At their other ends they have riveted control cams 6 with which they engage in the curves 7 of a cam 8. This cam disk sits firmly on the shaft 9 of the locking button es ii, which is provided with a reversible bracket io and which is rotatably mounted approximately halfway up the housing cover i, by means of a double flat connection. The cam 8 is covered by a circular cover plate 12. The whole thing is held together by a screw 13. The fork-shaped ends 5 of the bolts 4 are secured against stepping out of the nutell 2 by round disks 14 provided with a central bore. For the sake of clarity, the end plate 12, screw 13 and washers 14 - are omitted in FIG.

Die Spulenachsen, in Fig1.2 ist nur die Achseider Abwickelspule gezeichiin sitid in einer mit dem Gehäuse 16 fest verbundenen Platine 17, bzw. in einer Gehäusewand, fest eingenietet. Sie nehmen in üblicher Weise die Spulen 18 auf. Ihre freien Enden besitzen eine Eindrehung ig mit davorliegendem Bund 2o.The reel axes, in Fig. 1.2 only the axis of the unwinding reel is drawn sitid in a board 17 firmly connected to the housing 16, or in a housing wall, firmly riveted. They take on the coils 18 in the usual way. Your free ends have a recess ig with a collar 2o in front of it.

Zum Abschluß des Gehäuses wird der Deckel i aufgesetzt. Dabei treten die Enden ig, :2o der Spulenachsen 15 durch die Bohrung der Abdeckscheiben 14 hindurch und finden Platz in den Vertiefungen 2. Durch Verdrehen des Verriegelungsknopfes ii um etwa i8o' in Pfeilrichtung A werden durch das Kurvengetriebe 7, 6 die Riegel 4 in die Sp-errlage geschoben, in welcher deren gabelförmigen Enden 5 die Spufenenden in ihren Eindrehungen ig umfassen und so die Verriegelung des Deckels mit dem Gehäuse bewirken. Zum Entriegeln wird der Knopf ii in der umgekehrten Richtung um 18o' gedreht und zieht dann über das Kurverigetriebe 7, 6 die Riegel 4 außer Eingriff mit den Spulenachsenenden Ig, 20.To complete the housing, the cover i is put on. The ends ig,: 2o of the spool axles 15 pass through the hole in the cover disks 14 and find space in the recesses 2. By turning the locking button ii by about i8o 'in the direction of the arrow A , the cam mechanism 7, 6 locks the bolts 4 into the Sp-errlage pushed, in which the fork-shaped ends 5 enclose the Spufen ends in their indentations and thus effect the locking of the cover with the housing. To unlock, the button ii is rotated 18o 'in the opposite direction and then pulls the bolt 4 out of engagement with the coil axis ends Ig, 20 via the cam mechanism 7, 6.
