Storage "and clamping device on! Eigekopf for! photo and cinema cameras.

The! Fire has a head for photo and cinema cameras as an attachment on photographic tripods to the subject, in particular a storage and clamping device for the rotatable or scüenkbaren parts of such a device. For such a mounting "there is a requirement that the rotatable part is mounted with as little play as possible, while doing so can be rotated quickly and securely clamped. There are already a number of constructions to accomplish these requirements, but all of which are more or less complex and, above all, have a large number of individual parts. In contrast, the "proposal after the hiring is characterized by a particularly simple structure and" use only fewer individual parts, with completely play-free storage and effective clamping, as well as rapid rotation achieved will.

The basic idea of the proposal is that the rotatable part of the Uiger on the one hand on a bearing with a large diameter on the circumference of a mounted on the tripod Plate and on the other hand is guided on a cylindrical pin and held by means of a slotted clamping sleeve is pressed by one or more serrated rings for air-free storage of the rotatable part on the bearing pin will.

HaGh another feature is the bearing pin via the cylindrical bearing point for the rotatable part "and serves to accommodate a device for! clamping of the rotatable part on the fixed plate. The proposed construction will use only a few and simply designed parts a completely air-free storage and an effective clamping of the rotatable part is achieved in a particularly simple manner. On the one hand, this is achieved achieved by the double bearing of the rotatable part and on the other hand through the! fixation via the slotted, conical clamping sleeve by means of the pressed-on serrated ring (s).

The storage and clamping device after the "firing system can be used both for panoramic rotation, as equally apply for Ueigungsdrehung or, for example, only the panoramic rotation according to the proposal done and for Ieigungsdrehung any other device to be used.

In d.ex drawing an embodiment for the panorama rotation of a tilt head is shown.

Fig.l shows a longitudinal section through the Heigekopf,

Jig.2 shows a view of oils according to 3Tig, l, with the Clamping device is partially cut.

The plate 1 of the beige head, which is screwed onto a tripod with the thread 2 , has on its periphery a bearing surface 3 for the rotatable part 4 of the leige head. Of the

Part 4 is on the one hand on the Jüagerf lache .j and on the other hand on a cylindrical bearing pin 5, which is inserted into the plate 1 and expediently at the same time has an internal thread 2 for screwing the plate 1 onto a tripod. The bearing surface on the periphery of the plate 1 can be designed as a conical bearing jj or as a flat bearing surface 3> or in any other shape. The mounting and air-free adjustment of the rotatable part 4 takes place with the help of a conical, slotted clamping sleeve 6, preferably made of plastic, which is inserted into the part 4 from above and ^{braced by one or more serrated rings 7 3} ^ d- ^em bearing pin 5 will. To clamp the rotatable part 4 on the plate 1, a clamping piece 9 is arranged movably in the axial direction on a continuation 8 of the bearing pin 5 and is secured against rotation, for example by a pin 10 inserted in the pin part 8. To clamp the rotatable part 4 against the plate 1, the clamping piece 9 is pressed against a conical recess 12 in the part 4 by means of a locking screw 11 screwed onto the pin part 8, whereby the part 4 is clamped against the plate 1. On a corresponding extension 13 of the rotatable part 4, a pivot bearing with a clamping device of any design is arranged for tilting rotation of the camera carrier.
