ABSTRACT:
Quick attachment system for an appliance or instrument, e.g. a camera, with a mounting support and an insert connected to the appliance, which carries on its upper boundary surface the appliance to be fixed and is so insertable in the mounting support that, in the inserted state, the upper boundary surface of the insert is located substantially below the upper boundary surface of the mounting support, accompanied by the bracing of the appliance bottom against the upper boundary surface of the mounting support, characterized in that the insert has a square ground plan and trapezoidal cross-section, that the insert can be connected by a separate fastening screw and a twisting-preventing pin to the appliance or is constructed in one piece therewith, that an eccentric lever acting directly on the insert is provided for securing purposes, that the upper boundary surface of the insert is 0.5 to 1 mm below the upper boundary surface of the mounting support in the inserted state and that the outer portions of the underside of the appliance facing the insert in the inserted state engages on a much broader contour compared with the upper boundary surface of the insert, on the upper boundary surface of the mounting support.
