Abstract: A fixing system, for removably and adjustably fixing shelves and other objects comprising, at least a first elongated element in the form of a cable or a rod. A top end and an a bottom end of said cable or rod being firmly connected to at least one support surface by anchor pieces. A plurality of object supporting fasteners each cable of being fixed at an adjustable height on a first elongated element in an intermediate region thereof, which intermediate region is tensioned in a substantially vertical direction, and kept at a distance from the support surface by at least one first spacer extending general horizontally between the supporting surface and the elongated element.

Abstract: A device for fixing an element to an outer surface of a support wall of a hollow body in proximity to a first partition wall of this body perpendicular to said surface, including a bolt which extends through a part of the element and said support wall and cooperates with a nut bearing against an inner wall of the hollow body, parallel to said outer surface, wherein the nut is constituted by a plate in which is provided at least one tapped hole and to which is elastically fixed a fastener extending through an opening in the first partition wall. This opening permits the introduction of the plate, the fastener being itself elastically fixed to the first partition wall.

Abstract: The invention relates to a deposit system installation for transport trolleys. This deposit system comprises a locking line constituted by a substantially horizontal bar and deposit system apparatuses which are connected to the trolleys, whereby there is cooperation of longitudinal sliding within the line. Each deposit system apparatus comprises a coin system arranged to permit the separation of the apparatus from the locking line by the introduction of a deposition such as a coin into the apparatus. This deposit may then be liberated by the passage of the apparatus over a decoding station which is part of the locking line.

Abstract: The pedal carrier is so arranged as to permit mounting it and dismantling it in an easy manner with no use of a tool. For this purpose, each end of the pin (7) carrying the pedals is engaged in a sleeve (10,11) including a generally circular-shaped bearing surface (12) with two parallel flat portions, each bearing surface cooperating with the inner contour of an aperture (15) which has the same diameter and is provided in the side wall and communicates with the edge of this wall through a passage whose width is slightly greater than the distance between the flat portions, means being provided for immobilizing the assembly formed by the pin (7) and the sleeves (10,11) relative to the side walls (5, 6).

Abstract: Users need to be encouraged to return vehicles such as airport baggage trolleys or supermarket trolleys to a vehicle storage area. The area is equipped with an entrance fitted with a system for dispensing a reward for each vehicle returned to the area. The system comprises detector means (16, 17) for detecting the presence of a vehicle at the entrance to the storage area, control means for determining whether a vehicle has been effectively returned (and not just passed back-and-forth past the detector means), and means (23) for dispensing a reward such as a ticket exchangeable for a benefit of some kind for each returned vehicle.

Abstract: A method and an installation for encouraging the restitution of a vehicle such as a shopping cart in a reception area the access of which is controlled by wickets. The vehicle is twice identified at the entry of the reception area, by means counting for example the bars of a vehicle side, and causes the delivery of a ticket or the like when it has been identified and fully introduced in the reception area.
