Problems solved by technology

However, the structure of this method is relatively complicated, and due to the movement of the damping element, it also requires a large assembly space in the axial direction
In addition, due to the different creep behavior of the damping medium, there is a risk that the setting of the damping force cannot be maintained reproducibly when the damping elements are moved relative to each other, e.g. after some rotational movements
Another disadvantage is that these damping elements cannot be completely separated from each other, so it is not possible to set zero damping force

Embodiment Construction

[0025] figure 1 A partial top view of the tripod head of the present invention is given. figure 2 and image 3Shown in is the base body 10 (second body), the shaft 20 (first body) is rotatably installed in the base body 10 through the bearing 11, and is connected with the intermediate body of the tripod head not shown in the figure. The shaft 20 is rotatable about a pivot 21 relative to the base body 10, which is usually fixed on a tripod. The base body 10 in the illustrated embodiment comprises two half shells 12a, 12b.

[0026] In order to be able to damp the rotational movement of the shaft 20 relative to the base body 10 , a damping device 30 is provided. The damping device mainly includes a first damping element 31 and a second damping element 32 .

[0027] The first damping element 31 has an annular chassis 33 coaxial with the pivot 21 . Several concentrically arranged annular ribs 34 extend from the chassis 33 along the axis (along the direction of the pivot 21 )....

Abstract

A tripod head, in particular to hold a film or television camera, includes a first body and a second body, wherein the first body can be pivoted about at least one pivot axis relative to the second body, and a damping device to damp the pivoting movement of the first body relative to the second body, with a first damping element fixed to the first body and a second damping element, wherein the damping elements each have a plurality of concentrically arranged annular ribs which engage in cavities formed between the ribs of the respective other damping element and a damping medium is provided between the ribs of the damping element, wherein the second damping element is formed of at least two separate parts which are fixable independently of each other to the second body. The tripod head can be produced by a small amount of material and is easy to install. The tripod head only needs a small installation space and is adjustable in damping force.

Description

technical field [0001] The invention relates to a tripod head, also known as a cloud platform, in particular to a tripod head suitable for supporting film and television cameras. In particular, the present invention relates to a damping device, in particular a hydraulic damping device, for applying a damping force to the rotational movement of the first body of the tripod head relative to the second body of the tripod head. Background technique [0002] DE 2657692 A1 discloses a hydraulic damping device comprising a plurality of damping assemblies, each damping assembly comprising a first damping element and a second damping element. The damping element is composed of some annular discs and spacer discs arranged alternately and connected together. The annular disks of the first damping element engage in the shape of a comb between the annular disks of the second damping element. A damping medium, such as silicone oil, is filled between the individual annular disks. To adj...
