ABSTRACT:
A mounting arrangement for recessed lighting fixtures, includes a mounting ring with a cylindrical wall section for insertion in a ceiling opening. The mounting ring is provided with several holding elements, each of which being adjustable by a spindle between a first position in which the mounting ring is insertable in the ceiling opening and a second position in which the mounting ring is securely retained in the ceiling opening. Each holding element includes an angle plate received in a compartment of the mounting ring and having a short leg and a long leg. The angle plate is rotatably supported about a bolt which extends in the vertex of the angle plate and is connected to the spindle. Upon insertion of the mounting ring in the ceiling opening, the holding element occupies its first or upper position, with the long leg extending coextensive with the spindle and with the short leg being supported by the top edge of a rear wall of the compartment. Upon rotation of the spindle, the holding element is moved downwards and is pivoted into the second position, with the short leg bearing upon the inside surface of the rear wall and with the long leg radially projecting outwards to bear upon the edge of the ceiling plate.
