Motorized carriage that is movable in translation on a rail

Abstract

Motorized carriage (1) that is able to move in translation along a longitudinal axis (X) along a horizontal rail, said carriage (1) comprising at least one wheel (4), in particular of the friction wheel type, that is driven in rotation by an electric motor (5) and is mounted so as to pivot about a transverse axis (Y) on a holder (3) which carries said motor (5), said carriage (1) comprising a chassis (2) incorporating guide means (23, 24) mounted so as to slide on the chassis (2) along a vertical axis (Z) orthogonal to the longitudinal axis (X) and transverse axis (Y) and cooperating with elastic stressing means (25, 26) that are designed to move the guide means (23, 24) in the direction of the rail, where the holder (3) is in sliding contact with said guide means (23, 24) along the longitudinal axis (X) and vertical axis (Z), this sliding contact being designed to convert a movement of the holder (3) along the longitudinal axis (X) into a concurrent movement of the holder (3) along the vertical axis (Z) in the direction of the rail. Said carriage (1) can be used in video surveillance systems.
