Description
Die Erfindung bezieht sich auf ein Stativ für Geräte, insbesondere für photographische Kameras mit einem aus einer zwischen den Stativbeinen angeordneten Mittelsäule teleskopartig ausziehbarem Rohr, dessen oberes Ende die Gerätebefestigungseinrichtung trägt und auf dessen unteres Ende eine Rücklaufbremseinrichtung einwirkt.The invention relates to a stand for devices, in particular for photographic cameras with one of one arranged between the tripod legs Center column telescopically extendable tube, the upper end of which is the device fastening device carries and acts on the lower end of a reverse braking device.
Bei- den bekannten Einrichtungen dieser Art ist die Rücklaufbremseinrichtung für das Rohr als ein Klappenventil ausgebildet, welches sich beim Rücklaul des Rohres durch den dadurch entstandenen Luftdruck öffnet. Die Anordnung eines solchen Klappenventils ist jedoch zu umständlich und kostspielig. -ES ist Aufgabe der vorliegenden Erfindung, eine einfache und billige Art der Bremseinrichtung zu schaffen. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, d'aß die Rücklaufbremseinrichtung aus einer Drosselöffnung in der Mittelsäule besteht, durch welche das rücklaufendie Rohr die eingeschlossene Luft verdrängt.The reverse braking device is one of the known devices of this type designed for the pipe as a flap valve, which is when the pipe returns opens through the resulting air pressure. The arrangement of such a flap valve however, it is too cumbersome and expensive. -ES is the object of the present invention, to create a simple and cheap type of braking device. This task will solved according to the invention, d'ass the return braking device from a throttle opening in the central column, through which the tube runs back the trapped Displaced air.
Die weiteren Merkmale der Erfindung sind in den nachstehenden Ansprüchen an Hand eines Ausführungsbeispiels des Erfindungsgegenstandes näher erläutert. Es zeigt Fig. i das Stativ in Ansicht, Fig. 2 ,einem Querschnitt durch das untere Ende der Mittelsäule. Gemäß Fig. i besteht das Stativ aus drei ausziehbaren. Stativbeinen io, .welche die Mittelsäule ii tragen, aus der ein Rohr 12 teleskopartig ausziehbar und mittels .eines Klemmringes 13 in der jeweiligen Höhenstellung feststellbar ist. -Das Rohr 12 ist am oberen Ende mit einer Platte 14 verschlossen, welche einen Gewindebolzen. 15 zum Anschrauben dies Gerätes, beispielsweise einer photographischen Kamera, trägt. Im Unterteil der Mittelsäule i i ist eine Rücklaufbremse vorgesehen, welche nach dem Lösen des Klemmringes 13 ein automatisches und langsames Einziehen des Rohres 1-2 unter seinem Eigengewicht oder durch Handdruck ermöglicht.The further features of the invention are explained in more detail in the following claims using an exemplary embodiment of the subject matter of the invention. It shows Fig. I the stand in view, Fig. 2, a cross section through the lower end of the center column. According to Fig. I, the tripod consists of three extendable. Tripod legs io, .which carry the central column ii, from which a tube 12 can be telescoped out and locked in the respective height position by means of a clamping ring 13. -The tube 12 is closed at the upper end with a plate 14 which has a threaded bolt. 15 for screwing this device, for example a photographic camera, carries. In the lower part of the center column ii a return brake is provided which, after loosening the clamping ring 13, enables the pipe 1-2 to be drawn in slowly and automatically under its own weight or by hand pressure.
Zu diesem Zweck ist gemäß Fig. 2 das untere Ende des Rohres 12! mit einem Pfropfen 16 verschlossen:, an dem mit Hilfe einer Schraube 17 und einer Beitagsoheibe 18 eine Dichtmanschette ig aus Leder od. dgl. befestigt ist. Die Lippe der Manschette ig liegt an der Mittelsäule i i abdichtend auf. Das untere Ende der Mittelsäule i z ist mit einer Abachlußplatte 2o versehen; die in ihrer Mitte eine Drosselöffnung 21 aufweist.For this purpose, according to FIG. 2, the lower end of the tube 12! with a plug 16 closed: on which with the help of a screw 17 and a contribution washer 18 a sealing sleeve ig made of leather or the like. Is attached. The lip of the cuff ig is sealingly on the central column i i. The lower end of the center column i z is provided with a closure plate 2o; which has a throttle opening in its middle 21 has.
In Fig. 2 ist das Rohr 12 in seiner untersten Stellung gezeigt. Ist nun das Rohr i2 während des Betriebes nach oben ausgezogen und nachher durch Lösen des Klemmringes 13 zum Rücklauf freigegeben, dann wird die im Raum 2;2 zwischen der Abschlußplatte 2o und der Dichtmanschette i9 ein--geschlossene Luft unter Einwirkung der als Druckkolben wirkenden Teile ia@,16, ig d'urc'h die Drosselöffnung 21 ins Freie gedrückt und der Rücklauf des Rohres 1a dadurch entsprechend gedämpft bzw. gebremst.In Fig. 2, the tube 12 is shown in its lowest position. is Now the tube i2 is pulled out upwards during operation and then by loosening of the clamping ring 13 released to return, then the space 2; 2 between the end plate 2o and the sealing collar i9 - enclosed air under action of the parts acting as pressure pistons ia @, 16, ig d'urc'h the throttle opening 21 ins Pressed free and the return of the pipe 1a is accordingly dampened or braked.
Erwähnt sei noch, daß der Durchmesser der Drosselöffnung 2,1 einstellbar sein könnte, z. B. durch Einsetzen von ;geeigneten Drosselbüchsen in die Öffnung 2z. Dadurch kann die Schnelligkeit des Rohrrücklaufes den jeweiligen Betriebsbedingungen entsprechend geregelt werden.It should also be mentioned that the diameter of the throttle opening 2.1 is adjustable could be, e.g. B. by inserting suitable throttle sleeves into the opening 2z. As a result, the speed of the return pipe can vary depending on the operating conditions be regulated accordingly.
Schließlich sei noch bemerkt, daß an jedem der Stativbeine Rio ein Anschlag 23 angebracht ist zu dem Zweck, d@aß sich die Stativbeine io beim zusammengeklappten Stativ am Umfang der Abschlußplatte 2o anlehnen, wodurch eine Berührung zwischen den Stativbeinen und der Mittelsäule bzw. an ihr angeordneter Teile verhindert wird.Finally, it should be noted that there is a Rio on each of the tripod legs Stop 23 is attached for the purpose that the tripod legs io when folded Lean tripod on the circumference of the end plate 2o, creating a contact between the tripod legs and the center column or parts arranged on it is prevented.
