Description
Der Erfindungsgedanke erstreckt sich auf ein Stativ mit Zentralsäulen- oder Mittelsäulenverstellung. Bei den bekannten Stativen dieser Art erfolgt die Feststellung der Zentralsäule durch besondere Mittel, insbesondere durch eine Flügelmutter. Hierdurch wird im wesentlichen lediglich eine punktartige Festklemmung der Zentralsäule erzielt, die unbefriedigend ist und sehr oft eine ungewollte Verschiebung der Zentralsäule mit sich bringt. Diese Nachteile werden erfindungsgemäß dadurch vermieden, daß der zur gelenkigen Befestigung der Stativbeine dienende Hauptträger, in dessen mittlerer Bohrung die vertikal bewegliche Zentralsäule liegt, parallel zur Achse der Bohrung geschlitzt ausgebildet ist und zur Klemmung der Zentralsäule dient. In weiterer Ausgestaltung nach dem Erfindungsgedanken ist der Hauptträger über die ganze Höhe seiner mittleren Bohrung aufgeschnitten. Hierdurch wird, im Gegensatz zu dem Bekannten, eine kraftschlüssige Festklemmung der Zentralsäule über die gesamte Fläche der Ausbohrung gewährleistet, so daß eine ungewollte Verschiebung der Zentralsäule nach ihrer Festklemmung mit Sicherheit vermieden ist.The idea of the invention extends to a tripod with a central column or center column adjustment. In the known tripods of this type, the Detection of the central column by special means, in particular by a wing nut. This essentially only results in a point-like clamping of the central column achieved, which is unsatisfactory and very often an unwanted displacement of the central column brings with it. These disadvantages are avoided according to the invention in that the for the articulated attachment of the tripod legs serving main beam, in the middle one Bore the vertically movable central column is parallel to the axis of the bore Is slotted and is used to clamp the central column. In further Design according to the concept of the invention is the main beam over the entire height its middle hole cut open. In this way, in contrast to the known, a force-fit clamping of the central column over the entire surface of the bore guaranteed, so that an unwanted displacement of the central column after its clamping is certainly avoided.
In weiterer Ausgestaltung wird erfindungsgemäß eine Kleinmung der Zentralsäule, unter Benutzung der Gelenkachse eines Stativbeines bzw. der Gelenkachse eines der an dem Hauptträger drehbar befestigten Gelenkkörpers für die Stativbeine bewirkt. Als Feststellmittel kann ein auf dem einen Ende der Gelenkachse aufschraubbarer, mutterartig ausgebildeter Klemmgriff dienen.In a further refinement, according to the invention, the Central column, using the joint axis of a tripod leg or the joint axis one of the articulated bodies for the tripod legs, which are rotatably attached to the main support causes. A locking device that can be screwed onto one end of the joint axis can be used as a Nut-like clamping handle are used.
Die Figuren zeigen ein Ausführungsbeispiel na--h dem Erfindungsgedanken.The figures show an exemplary embodiment based on the concept of the invention.
Fig. i ist eine Ansicht von oben auf den Stativkopf, teilweise im Schnitt; Fig. 2 zeigt den Stativkopf von vorn, in Richtung auf die Klemmvorrichtung. Hierbei sind die Gelenkgabeln für die beiden anderen Stativbeine fortgelassen.Fig. I is a top view of the tripod head, partially in Cut; Fig. 2 shows the tripod head from the front, in the direction of the clamping device. The joint forks for the other two tripod legs have been omitted.
Der Hauptträger a, in dessen mittlerer Bohrung die vertikal bewegliche Zentralsäule c liegt, ist nach Art einer Rohrschelle ausgebildet. Zu diesem Zweck ist der Hauptträger über die ganze Höhe der mittleren Bohrung aufgeschnitten und mit Klemmstücken d versehen. An dem Hauptträger a sind in an sich bekannter Weise Gelenkkörper vorgesehen, an denen die geschlitzt ausgebildeten Gelenkgabeln e und f drehbar befestigt sind. Auf den zylindrischen Ansatzstutzen i der Gelenkgabeln e und f sind die Stativbeine angeordnet. Die Klemmstücke d bilden zugleich den Gelenkkörper zur Aufnahme der Achse g. Auf dieser ist die Gelenkgabel e gelagert, und zwar derart, daß sie mit ihren Innenflächen m an den Klemmstücken d liegt. Die Gelenkachse g ist mit Gewinde versehen, welches zum Aufschrauben eines mutterartigen Klemmgriffes 1e dient. Durch Bedienen des Klemmgriffes 1a werden die Gelenkgabel e und die Klemmstücke d des Hauptträgers a zusammengedrückt, so daß sich die Breite des Schlitzes b des Hauptträgers a entsprechend verringert und die Zentralsäule c über die gesamte Fläche der mittleren Bohrung des Hauptträgers a festgeklemmt wird. Nach Lösen des Klemmgriffes le kann die Zentralsäule c gewollt verstellt werden.The main beam a, in the middle bore of which the vertically movable central column c is located, is designed in the manner of a pipe clamp. For this purpose, the main beam is cut open over the entire height of the central hole and provided with clamping pieces d. On the main support a, joint bodies are provided in a manner known per se, on which the joint forks e and f , which are designed with slits, are rotatably fastened. The tripod legs are arranged on the cylindrical connecting pieces i of the joint forks e and f. The clamping pieces d at the same time form the joint body for receiving the axis g. The joint fork e is mounted on this, in such a way that it lies with its inner surfaces m on the clamping pieces d. The joint axis g is provided with a thread which is used to screw on a nut-like clamping handle 1e. By operating the clamping handle 1a, the joint fork e and the clamping pieces d of the main beam a are pressed together, so that the width of the slot b of the main beam a is reduced accordingly and the central column c is clamped over the entire area of the central bore of the main beam a. After releasing the clamping handle le, the central column c can be adjusted deliberately.
