Ball head assembly for attaching optical and/or electronic equipment to a stand

Abstract

A ball head assembly for attaching an optical and / or electronic device to a mount having at least two degrees of freedom of adjustability is disclosed, the assembly having a first portion and a second portion, the first portion being releasably connectable To the bracket, the second part is provided with a support element for releasably connecting the held device, one of the two parts being a spherical head (20, 100) having an at least partially spherical body ( 21, 99), the other part includes a chamber formed as a spherical section that at least partially surrounds the spherical head (20, 100) and cooperates with the spherical head, the spherical head assembly also includes an adjustment device, the adjustment device is used Upon coupling the two parts together and releasing the coupling, the retained device is adjusted to a horizontal or nearly horizontal position in the initial position intended for use. In the second part there is provided a groove (24, 108) having a vertical center plane and extending along the largest diameter of the spherical section, provided on the first part at a position corresponding to the vertical diameter of the spherical section There are circular symmetrical columns (25, 103) which can be fitted in the grooves (24, 108), in the fitted position the columns (25, 103) allow and guide the two parts along said grooves (24 , 108) is displaced, and the column (25, 103) allows the two coupled spherical fit sections to rotate around the vertical axis of the column (25, 103) at each adjustment position, and the adjustment device is arranged at On the one of the two parts with the spherical cavity, the adjusting means presses the cavity to the spherical body (21, 99) when the positions of the two parts are fixed.

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
