Abstract:
1. A supporting device ( 10 ) for a lighting appliance comprising a frame ( 11 ) in turn comprising a tubular portion ( 12 ) which can be at least partially inserted in a housing or opening ( 17 ) of a false ceiling or wall ( 18 ), characterized in that it comprises supporting means ( 20 ) comprising at least two levers ( 30 ) associated with the frame ( 11 ) and capable of passing, by rotation, by means of two corresponding unidirectional couplings ( 34 , 52 ) from a disengagement operating position, in which they do not protrude from said tubular portion ( 12 ), to an engagement operating position in which they protrude from said frame ( 11 ) becoming coupled with said wall ( 18 ) to support the device ( 10 ), the supporting device further characterized in that the at least two unidirectional couplings ( 34 , 52 ) allow the corresponding lever ( 30 ) to only pass from the disengagement position to the engagement position through a rotational movement, but not vice versa, said at least two unidirectional couplings ( 34 , 52 ) further comprised in that the unidirectional couplings comprise at least one knurled portion ( 52 ) and at least one overhanging portion ( 34 ) said lever ( 30 ) is further characterized in that it is at least partially constructed out of a flexible resilient material.
