Spherical Head Assembly for Attaching an Optical and/or Electronic Device to a Stander

Spherical head assembly for attaching an optical and/or electronic device to a stander with an adjustability in at least two degrees of freedom, having an initial position of intended use in which the device is adjusted to take a horizontal or almost horizontal position, wherein the spherical head assembly has a first part which can be connected and fixed to the stander in a releasable way and a second part which is provided with a support element for the releasable connection and holding of the device, and one of the two parts comprises a spherical head (20, 100) that has a body (21, 99) which has at least in part a spherical segment, 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 the spherical head assembly comprises an adjusting means for coupling the two parts together and releasing the same coupling, wherein that one of the first and second parts which comprises the spherical cavity is coupled in a non-adjustable way to the cavity;

• and that has a vertical central plane in said initial position that extends along the largest diameter of the associated spherical segment, and a circularly symmetrical stud (25, 103) having an axis is provided on the first part at a position that corresponds to the vertical diameter of the groove (24, 108) and the stud (25, 103) can be fitted in the groove (24, 108), and in the fitted position the stud (25, 103) allows and guides the relative 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 axis of the stud (25, 103) at each displaced positions of the two parts, and the adjusting means is arranged on that one of the two parts which comprises the spherically shaped cavity, and the adjusting means presses the form fitting cavity and the spherical body (21, 99) to each other for fixing the position of the two parts in any required adjusted position without causing deformation to the spherical segment of the body (21, 99).
