Description
Die ausziehbar en Schenkel und Mittelsäulen an fotografischen Stativen müssen in ihrer jeweils"eingenommenen lage festlegbar sein. Hierzu werden llemmvorriehtungen verwendet.The extendable legs and central columns on photographic tripods must be determinable in the position they occupy. Terminal devices are used for this purpose.
Bei einer "bekannten Elemmvorrichtuhg zur Sicherung der Stativsäule wird ein Druckstück-verwendet, welches mittels einer Feder die Stativsäule gegen die Innenwand der sie aufnehmenden Mhrungsnabe im Stativkopf preßt. Zum lösen dieser Klemmvorrichtung ist ein von Hand: zu betätigender Hebel vorgesehen. Das Druckstock und die Feder sind in einer Ausnehmung- eines radial von der rungsnabe naeh außen verlaufenden Ansatzes untergebracht, der auch ein Befestigungsteil für ein Halteblech besitzt, welchesmit zur Bildung der .Pederehtlastungs-Hebelmechänik" dient.In a "known Elemmvorrichtuhg for securing the stand column, a pressure piece is used, which by means of a spring the stand column against the inner wall of the Mhrungsnabe receiving it presses in the tripod head. To release this clamping device a manually operated lever is provided. The printing block and the springs are in a recess - one radially from the rungsnabe housed near the outside approach, the also has a fastening part for a retaining plate, which with to form the .Pederehllastungs-Hebelmechänik "is used.
Die "bekannte" Klemmvorriciitung. ist verhältnismäßig verwickelt im Aufbau und benötigt, darüberhinaus verhältnismäßig viel Bauteile. Auch wird zu ihrer Verwirklichung für den lührungsnabenansatz eine verhältnismäßig große radiale Baulänge benötigt, weshalb sie allein schon aus diesem Grunde zur Verwendung an den Stativschenkeln ungeeignet ist, da sie hier zu weit nach außen vorspringen würde. :The "well-known" clamping device. is relatively involved in Structure and also requires a relatively large number of components. Also, for the leadership hub approach, a requires a relatively large overall radial length, which is why they are used on the tripod legs for this reason alone is unsuitable because it would protrude too far outward here. :
Durch die Neuerung soll nun eine Klemmvorrichtung geschaffen werden, die verhältnismäßig wenig Bauteile umfaßt, einfach einzubauen ist und an den Stativschenkeln nur wenig vorsteht. Außerdem soll sie die Möglichkeit der bequemen Bedienung bieten.The innovation is now to create a clamping device, which comprises relatively few components, is easy to install and only protrudes slightly from the tripod legs. Besides that it should offer the possibility of convenient operation.
Zur lösung der damit gegebenen Aufgabe wird bei der Neuerung von einer Klemmvorrichtung für die ausziehbaren Schenkel fotografischer Stative mit einem den ausziehbaren Schenkel mittels einer Feder gegen die Innenwand des ihn aufnehmenden Hohlschenkels pressenden Druckstück ausgegangen, wobei die Feder durch Handbetätigung entlastbar ist. An einer solchen Klemmvorrichtung besteht die Erfindung darin, daß das Druckstück als eine quer verschiebliehe, in den Hohlschenkel ragende und diesen nach außen durchdringende, vom ausziehbaren Schenkel frei durchsetzte Büchse ausgebildet ist und daß die Feder sich einerseits an der Außenwand des Hohlschenkels, anderseits an der außerhalb desselben liegenden Innenwand der Büchse abstützt und daß die außerhalb des Hohlschenkels:liegende Außenwand der Büchse zugleich als Feder-"betatigungshartdhabe^ient. Bes^onders^vorteilhaft^ist es dabei, wenn die Büchse eine bis zur Außenwand reichende QuerausnehmungTo solve the given task, the innovation of a clamping device for the extendable legs photographic Tripods with one of the extendable legs by means of a spring against the inner wall of the hollow leg receiving it pressing pressure piece assumed, the spring by manual actuation can be relieved. In such a clamping device, the invention consists in the fact that the pressure piece can be displaced transversely as a bushing protruding into the hollow limb and penetrating it to the outside, freely penetrated by the extendable limb is formed and that the spring is on the one hand on the outer wall of the hollow limb, on the other hand on the one lying outside it The inner wall of the bushing is supported and that the outer wall of the bushing, which is located outside the hollow limb, is also used as a spring "actuation harddhabe". It is particularly advantageous to if the bushing has a transverse recess extending to the outer wall
aufweist und wenn, auf der Höhe der so entstehenden, in Büchsenlängsriehtung voneinander entfernten Ringteile ini Hohlschenkel Quersclilitze vorgesehen sind, durch welche die Ringteile verschieblich in den Eohlschenkel ragen.has and if, at the level of the resulting, in Büchsenlängsriehtung ring parts spaced apart from one another are provided ini hollow leg cross-brace, through which the ring parts are displaceable protrude into the thigh of the ears.
Die leuerung ist nachstehend anhand der Zeichnung erläutert, die ein Äusführungs"beispiel veranschaulicht. Dabei zeigensThe control is explained below with reference to the drawing, the an exemplary embodiment illustrated
Mg. 1 ein Eeilstück eines Stativbeines mitMg. 1 an Eeilstück of a tripod leg with
ausziehbarem Schenkel und Klemmvorrichtung, längsgeschnitten,extendable leg and clamping device, cut lengthways,
Fig. 2 einen Querschnitt entlang der Linie H-II in Mg. 1.FIG. 2 shows a cross section along the line H-II in Mg. 1.
Der ausziehbare, mittels Rundrohr gebildete Schenkel 1 kann in dem Vierkanthohlschenkel 2 axial verschoben werden. Dessen Vorderwand 3 ist, wie insbesondere aus Fig. 1 hervorgeht, verstärkt. In den Hohlschenkel 2 ragt radial eine aus einem Rechteckrohrstück gebildete Büchse 4 ein. Diese Büchse weist eine bis zur Außenwand 5 reichende Ausnehmung 6 auf, wodurch zwei in Büclisenlängsrichtung voneinander entfernte Singteile 7 und 8 entstehen, die an der Außenwand 5 beginnen und auch an dieser enden. Auf der Höhe dieser Ringteile 79 8 sind in der Hohlschenkel-Vorderwand 3 Querschlitze 9 und 10 vorgesehen, durch welche die Singteile 7, 8 in den Hohlschenkel 2 ragen. Durch die Ringteile J, 8 ist innerhalb des Hohlschenkels 2 der ausziehbare Schenkel 1 geführt.The extendable leg 1, formed by means of a round tube, can be moved axially in the square hollow leg 2. The front wall 3 thereof is reinforced, as can be seen in particular from FIG. 1. A bushing 4 formed from a rectangular tube protrudes radially into the hollow limb 2. This bushing has a recess 6 reaching as far as the outer wall 5, as a result of which two singing parts 7 and 8, which are spaced apart in the longitudinal direction of the Büclisen and which begin at the outer wall 5 and also end at this, are produced. At the level of these ring parts 7 9 8, 3 transverse slots 9 and 10 are provided in the hollow limb front wall, through which the singing parts 7, 8 protrude into the hollow limb 2. The pull-out leg 1 is guided through the ring parts J, 8 within the hollow leg 2.
Die Ringteile 7 und 8 sind auf.der der Vorderwand 3 abgekehrtenThe ring parts 7 and 8 are on the front wall 3 facing away
(Seite nach Art eines Mhrungsprismas 11 gestaltet. Zwischen die Außenwand 5 der Druckstück-Büchse 4 und die Vorderwand 3 des Hohlschenkels 2 ist eine !Druckfeder 12 eingesetzt, die sich einerseits an der Außenseite 13 der Vorderwand 3 und anderseits an der Innenseite 14 der Außenwand 5 abstützt.(Side designed in the manner of a miter prism 11. Between the Outer wall 5 of the pressure piece bushing 4 and the front wall 3 of the hollow leg 2, a compression spring 12 is used, which on the one hand on the outside 13 of the front wall 3 and on the other hand on the inside 14 of the outer wall 5.
Durch den Druck der Feder 12 bedingt, wird der Schenkel 1 klemmend im Hohlschenkel 2 festgelegt. Um den Schenkel 1 axial verschieben zu können, gentigt es, auf die Außenwand 5 in Gegenrichtung des Pfeiles A von Hand einen die Feder 12 entlastenden Druck aufzubringen. Der Schenkel 1 erhält seine führung durch die Innenseite der Vorderhand 3 und das führungsprisma 11.Due to the pressure of the spring 12, the leg 1 becomes jammed set in the hollow leg 2. In order to be able to move the leg 1 axially, it is necessary to move onto the outer wall 5 in the opposite direction of arrow A to apply a pressure relieving the spring 12 by hand. The leg 1 receives its leadership through the inside the forehand 3 and the guide prism 11.
