Description
Stativkopf. Die bekannten Stativköpfe f är photographische Apparate, Feldmeßgeräte u. dgl., bei denen eine mit dem Instrumententräger verbundene Kugelschale zwischen zwei sie umfassenden Kugelflächen durch Verschraubung festklemmbar ist, haben den Nachteil, daß das in eine bestimmte Lage eingestellte Gerät beim Anziehen der Klemmschrauben oft wieder verschoben wird. Dieser Nachteil rührt daher, daß die beiden umfassenden Kugelflächen nicht nur einander genähert werden, sondern daß sie auch eine Verdrehung zueinander ausführen können, wobei sie die zu klemmende Kugelschale mitnehmen.Tripod head. The well-known tripod heads for photographic apparatus, Field measuring devices and the like, in which a spherical shell connected to the instrument support can be clamped between two spherical surfaces encompassing them by screwing, have the disadvantage that the device, which is set in a certain position, is tightened the clamping screw is often moved again. This disadvantage arises from the fact that the two encompassing spherical surfaces are not only brought closer to one another, but that they can also perform a rotation to each other, whereby they are to be clamped Take the spherical shell with you.
Der Erfindung gemäß wird dieser Nachteil dadurch behoben, daß die die klemmenden Kugelflächen aufweisenden Teile des Stativkopfes durch eine Parallelführung miteinander verbunden und dadurch gegen eine Verdrehung gesichert sind. Die Parallelführung besteht vorzugsweise aus Stiften, die an dem einen der beiden klemmenden Teile vorgesehen sind und in entsprechende Bohrungen des zweiten Klemmorganes hineinragen.According to the invention, this disadvantage is eliminated in that the the parts of the tripod head having the clamping spherical surfaces by a parallel guide are connected to each other and thus secured against rotation. The parallel guide preferably consists of pins which are provided on one of the two clamping parts are and protrude into corresponding bores of the second clamping member.
Abb. r der ein Ausführungsbeispiel des Gegenstandes der Erfindung veranschaulichenden Zeichnung zeigt den neuen Stativkopf im Schnitt nach der Linie B-B der Abb. 2 ; Abb. 2 stellt einen Schnitt nach der Linie A-A der Abb. z dar.Fig. R of an embodiment of the subject matter of the invention The illustrative drawing shows the new tripod head in section along the line B-B of Fig. 2; Fig. 2 shows a section along the line A-A in Fig. Z.
Die Grundplatte lt des Stativkopfes kann in bekannter Weise mittels eines Gewindes e auf einen Gewindezapfen der Stativplatte aufgeschraubt werden. Der Träger zc trägt an seinem unteren Ende eine Kugelschale m, die zwischen einer zweiten mit der Stativplatte lz fest verbundenen Kugelschale 0 und einem Kugelsegmente iz festgeklemmt werden kann. Die Kugelschale 0 ist an ihrem Scheitel kreisförmig ausgenommen, um das Verschwenken des Gerätträgers 2s innerhalb des erforderlichen Winkels zu gestatten. Bei der dargestellten Ausführungsform erfolgt das zum Klemmen der Schale m erforderliche Anheben des Kugelsegmentes n mittels einer zwischen der Grundplatte h des Stativkopfes und dem Kugelsegmente n liegenden, zylindrischen, an ihrer Unterfläche mit Gewinden versehenen Platte a, die in den untersten zylindrisch gestalteten Teil der Schale 0 eingeschraubt ist. Zur Ausführung dieser Bewegung ist die Platte a mit einem nach ihrem Einschrauben in die Schale 0 angebrachten Griff ro versehen, der durch einen Schlitz w der Schale 0 nach auswärts reicht.The base plate lt of the tripod head can be screwed in a known manner by means of a thread e on a threaded pin of the stand plate. The carrier zc carries at its lower end a spherical shell m, which can be clamped between a second spherical shell 0 firmly connected to the stand plate lz and a spherical segment iz. The spherical shell 0 is recessed circularly at its apex in order to allow pivoting of the device carrier 2s within the required angle. In the embodiment shown, the lifting of the spherical segment n required to clamp the shell m takes place by means of a cylindrical plate a, which is provided with threads on its lower surface and is located between the base plate h of the tripod head and the spherical segments n, which is inserted into the lowest cylindrical part of the shell 0 is screwed in. To carry out this movement, the plate a is provided with a handle ro which is attached after it has been screwed into the shell 0 and which extends outward through a slot w in the shell 0.
Um das Verdrehen des Segmentes n während des Anziehens der Platte a zu verhindern, sind auf der Platte h Stifte t angeordnet, die durch bogenförmige Schlitze s der Platte a reichen und, in kurze Bohrungen des Sektors n hineinragend, eine Parallelführung dazu bilden. Die Platte a ist mit der Schale 0 mittels mehrerer am Rande derselben verteilte Schrauben verbunden oder kann in Form eines mit Flansch versehenen Deckels gleichfalls in die Schale 0 eingeschraubt sein.In order to prevent the rotation of the segment n during the tightening of the plate a, pins t are arranged on the plate h , which extend through the arcuate slots s in the plate a and, protruding into short bores in the sector n, form a parallel guide. The plate a is connected to the shell 0 by means of a plurality of screws distributed on the edge of the same or can likewise be screwed into the shell 0 in the form of a cover provided with a flange.
