Abstract: A system for locking a platform screen door leaf, the leaf being capable of moving by a horizontal translational movement in a plane of the leaf between open and closed positions, including a bearing rail mounted on the leaf and having a reception recess, a motor body forming the stator of a drive motor of the leaf and mounted freely in rotation about a motor axis on a gear unit, a locking roller mounted projecting on the motor body and arranged so as to roll along the bearing rail during a movement of the leaf, and engage, by a rotation of the motor body, in the reception recess when the leaf reaches the closed position or the open position, in order to lock.

Abstract: A system for guiding and supporting a leaf of a platform-access door capable of moving relative to a fixed panel in a horizontal translational movement in a plane of the leaf between open and closed positions, includes a rail extending in a direction of the horizontal translational movement, a first set of rollers collaborating with the rail with and being made up of: a main roller in contact with a lower bearing surface of the rail; first and second secondary rollers which are vertically offset from one another and are respectively in contact with the lower bearing surface and with an upper bearing surface of the rail and are spaced from the main roller.

Abstract: A system for guiding and supporting a leaf of a platform-access door capable of moving relative to a fixed panel in a horizontal translational movement in a plane of the leaf between open and closed positions, includes a rail extending in a direction of the horizontal translational movement, a first set of rollers collaborating with the rail, for guiding and supporting it, with an axis of rotation perpendicular to the plane of the leaf and being made up of: a main roller in contact with a lower bearing surface of the rail; first and second secondary rollers which are offset from one another in at least a vertical direction and respectively in contact with the lower bearing surface and with an upper bearing surface of the rail and positioned some distance away from the main roller in the direction of a transition from the closed position into the open position.
