Description

Es ist bei Objektivträgern, welche mit dem Objektivträgerschlitten federnd verbunden sind, bereits bekannt, eine Versteifung anzubringen, welche in Tätigkeit tritt, wenn der 5 Objektivträger mit seinem Schlitten aus dem Kameragehäuse herausgezogen wird, sich aber selbsttätig wieder löst, wenn er in das Kameragehäuse eingeschoben wird. Es ist ferner bekannt, mit Hilfe federnder Handhaben, an welchen der Objektivträger aus dem Kameragehäuse herausgezogen wird, den Objektivträger an seiner Führung festzuklemmen, ebenso wie es üblich war, die vorgenannten beiden Vorrichtungen so zu vereinigen, daß die Versteifungsvorrichtung "für den Objektivträger mit seinem Schlitten zugleich den Objektivträger-an seiner Laufbahn festklemmt.It is in the case of lens carriers, which are resiliently connected to the lens carrier slide are already known to attach a stiffener, which comes into action when the 5 lens carrier is pulled out of the camera body with its slide but automatically releases again when it is pushed into the camera housing. It is also known, with the help of resilient handles, on which the lens carrier from the camera housing is pulled out to clamp the lens carrier on its guide, just as it was customary to combine the aforementioned two devices in such a way that that the stiffening device "for the lens carrier with its slide at the same time the lens carrier clamped on its track.

Diesem Bekannten gegenüber zeigt die Erfindung insofern wesentliche Vorteile, als das Klemmittel in seiner Voll- oder einer Teillänge der Führungskante des Objektivträgers als auch seines Schlittens als seitlich verschwing- oder schiebbarer federnderTeil ausgebildet ist und die Verbindungsachse der beiden Gleitteile gleichzeitig als Lager für die Preßfeder dieses Schwing- oder Schiebeteiles dient.Compared to this known, the invention shows significant advantages in that Clamping means in its full length or part of the length of the leading edge of the lens carrier as well as its slide designed as a laterally swingable or slidable resilient part is and the connecting axis of the two sliding parts at the same time as a bearing for the compression spring of this oscillating or sliding part serves.

Ein weiteres Merkmal der Erfindung ist, daß ohneVerschwingung des oder der Klemmteile keine vollständige Entkuppelung derselben zur Laufbahn hervorgerufen, sondern nur der Klemmdruck derselben gemildert wird und das Umlegen des Objektivträgers und seines Klemmittels um die gleiche Dreh- oder Federtragachse erfolgt.Another feature of the invention is that there is no vibration of the clamping member or members no complete decoupling of the same from the raceway caused, but only the clamping pressure of the same alleviated and the folding of the lens carrier and its clamping means around the same rotational or spring support axle.

Eine Ausführungsform des Erfmdungsgegenstandes ist zeichnerisch wiedergegeben, und. zwar zeigt Abb. 1 denselben, in den Laufsctuenentragteil eingeschoben, in Aufsieht, Abb. 2 eine Unteransicht des Laufschlittens nebst Klemmvorrichtung, Abb. 3 einen Schnitt A-A zu Abb. 2, Abb. 4 eine Rückansicht zu Abb. 2.An embodiment of the subject matter of the invention is shown in the drawing, and. Although Fig. 1 shows the same, pushed into the barrel support part, looking up, Fig. 2 shows a bottom view of the carriage together with the clamping device, Fig. 3 is a section AA to Fig. 2, Fig. 4 is a rear view of Fig. 2.

Auf dem Laufboden α des Kamerage- *5 häuses b befindet sich der die Führungsschienen c¹, c" tragende Teil c. In die Schienen greifen die Schlittenteile d, d¹ ein. Der hintere Schlittenteil d¹ ist mit dem vorderen Teil d durch Scharnier e verbunden und dient der Standarte / oder deren Objektivträgerschlitten f¹ zum Lager. Die Achse e¹ der Schraubenfeder e~ ist zwischen die Lager e⁵, e^l der Schlittenteile d, d¹ gespannt, wobei das Lager e⁴ einer weiteren Feder g als Anlager dient, die pressend auf das Scharnier h wirkt, so daß dessen äußere Fläche h° sich gegen die Innenfläche des Lagers e⁵ legt. Das Scharnier h verbindet zwei Teile h¹, h" miteinander, die unterhalb der Lauf schlittenteile d, d^x um Lager h³ mittels eines Griffes A⁴ schwenkbar sind und die sich an ihren inneren, sich zunächst liegenden Enden durch Anlager W, h⁸ gegenseitig gegen Verbiegung versteifen. Die Achse e¹ bildet dabei auch die Achse für die Teile Ii¹, h², The part c carrying the guide rails c ¹ , c ″ is located on the running floor α of the camera housing b . The slide parts d , d ¹ engage in the rails. The rear slide part d ¹ is hinged to the front part d connected e and serves to standard / or the lens carriage f ¹ to the stock. the axis e ¹ of the coil spring e ~ is between the bearing e ^5, e ^l of the carriage parts d, d ¹ tensioned, the bearing e g ⁴ a further spring as An abutment is used, which has a pressing effect on the hinge h , so that its outer surface h ° lies against the inner surface of the bearing e ^5. The hinge h connects two parts h ¹ , h ″ with one another, the slide parts d, d ^x are pivotable about bearing h ³ by means of a handle A ⁴ and are mutually stiffened against bending at their inner, initially lying ends by bearings W, h ^8. The axis e ^{1 also} forms the axis for the parts Ii ¹ , h ² ,

deren in die Laufschienen c¹, c² eingreifende seitliche Kanten W, A⁰ als Führttngs- und Klenimittel dienen.whose lateral edges W, A ⁰ engaging in the running rails c ¹ , c ² serve as guide and clamping means.
