Abstract:
A protective housing comprising:a back wall having a cable entrance;a window wall for an optical apparatus with an optical axis;the protective housing also comprising, for the orientation of said optical axis, a mounting system with at least first, second and third lockable links, said mounting system comprising pivot axes and a mounting body; said mounting body comprising a lockable rotary receptacle with a first pivot axis and a contact surface for attachment to a mounting surface; wherein the first pivot axis of the rotary receptacle is aligned perpendicular to said contact surface; said mounting system having at least one additional pivot axis which is aligned perpendicular to said first pivot axis, wherein:a) between said back wall and said mounting body first, second and third links are disposed, said first link being connected through the rotary receptacle to the mounting body and said third link to the back wall;b) wherein at least two said additional pivot axes are disposed between said links, said additional pivot axes are aligned perpendicular to one another and to said first pivot axis of the rotary receptacle, one of said additional pivot axes being aligned horizontally in the assembled state of the protective housing, and the other additional pivot axis is aligned perpendicular;c) said links enclosing a cable tunnel which can be brought to the outstretched position and leads to the cable entrance in said back wall;d) wherein said first link and said third link have each a partially spherical shell whose outside surfaces are directed against one another and which have each an opening, said first pivot axis and said second pivot axis stand vertically one on the other and pass through the center point of the partially spherical shell of said first link, and said third pivot axis passes through the center of said partially spherical shell of said third link;e) said second link being configured as a rectilinear hollow body and passing through the openings for rotation about the centers of said partially spherical shells;f) the interior of said partially spherical shells thrust bodies having external rotation surfaces which at least partially cover over the openings and are joined in a tension-resistant manner to the two ends of said second link; andg) clamping means are provided by which said two thrust bodies together with the second link can be locked to said partially spherical shells against rotation and displacement.
