Spherical head assembly for attaching optical and/or electronic device to stander

Abstract

Spherical head assembly for attaching an optical and / or electronic device to a stander with an adjustability in at least two degrees of freedom, which has a first part that can be releasably connectedto the stander and a second part which is provided with a support element for the releasable connection of the device to be held thereby, and one of the two parts is a spherical head (20, 100) that has a body (21, 99) which has at least in part a spherical shape, and the other part comprises a cavity formed as a spherical segment which encircles the spherical head (20, 100) at least in part and is fitted thereto, and comprises an adjusting means for coupling the two parts together and releasing the same coupling, and in the initial position of intended use the held device is adjusted in horizontal or almost horizontal position. In the second part a groove (24, 108) is provided that has a vertical central plane and extends along the largest diameter of the spherical segment, and on the first part a circularly symmetrical stud (25, 103) is provided at a position that corresponds to the vertical diameter of the spherical segment and the stud (25, 103) can be fitted in the groove (24, 108), and in the fitted position the stud (25, 103) allows the displacement of the two parts along the groove (24, 108), and the stud (25, 103) allows the turning of the two coupled spherical fitted segments around the vertical axis of the stud (25, 103) at each of the adjusted positions, and the adjusting means is arranged on that one of the two parts which has the spherically shaped cavity, and when the position of two parts are fixed the adjusting means presses the cavity to the spherical body (21, 99).

Description

technical field [0001] The present invention relates to a ball head assembly for attaching an optical and / or electronic device to a mount, the ball head assembly having at least two degrees of freedom of adjustability, wherein the ball head assembly has features connectable to the mount and A first part is releasably secured to the bracket and a second part is provided with support elements for releasably attaching and holding said device. The spherical head assembly according to the invention can be used primarily for holding and positioning of optical equipment such as cameras, video and film recorders and projectors and which are designed to be held on a type of stand, typically on a tripod superior. Background technique [0002] More precisely, one of the aforementioned two parts of the spherical head assembly consists of a spherical head with a spherical body at least partially formed as a sphere, and the other part comprises a chamber designed as a spherical cross-sec...

Problems solved by technology

In this "reverse" design, the positioning of the reference plane cannot be ensured, i.e. the reduction of the degrees of freedom from three to two is carried out in such a way that the horizontal line can fit onto the support reference plane in each adjustment position
