Abstract: This optical assembly comprises a securing support (40), an optical focusing element (44) and a reflecting mirror (42) which is suitable for reflecting an incident light beam (F1) towards the optical focusing element (44) in order to focus it onto an illumination plane (P). The reflecting mirror (42) is movable relative to the securing support (40). The optical focusing element (44) is movable relative to the securing support (40). The assembly includes elements for connecting the focusing element (44) to the mirror (42) for synchronised displacement of the two of them. The assembly is useful in devices for illuminating operating fields.

Abstract: The structure is suspended from the ceiling of a room in a hospital or a clinic and includes a substantially vertical arm adapted to support medical equipment such as a cart above the floor. For this purpose, the structure has a support column for supporting the medical equipment, the column being connected to the vertical arm, and an intermediate support on which said medical equipment is loaded and which is hinged to the column and forms an external cover therefor. The structure also has means for adjusting the position of the intermediate support relative to the column so as to correct departures of the on-board equipment from the horizontal.

Abstract: Support structure/transport trolley (C) assembly having a support structure (S), such as a ceiling mount intended for a hospital building treatment room, comprising at least one arm (2) equipped with one or more vertical columns (3) and a fixing device (1) allowing the structure (S) to be fixed to the ceiling or to a wall; a mobile transport trolley (C) bearing attachment (31) which cooperate with a receiving device (32) borne by a column (3) to allow the trolley (C) to be fixed to the column (3); and a lifting device (33) also borne by the trolley (C) capable of allowing the lifting of at least part of the trolley (C) after this trolley has been fixed to the column (3).
