  • Patent number: 7322298
    Abstract: The invention relates to a flexible floor designed to be suspended from an undulating flexible bellows in order to form a corridor connection module, said floor presenting undulating raised edges at its transverse ends, and, on its bottom face, transverse ribs in which metal reinforcements are embedded. According to the invention, at least some of the metal reinforcements have ends that project beyond the transverse ribs, each of which projecting ends is coupled to a fastening device for fastening the floor to the bellows, which fastening device extends alongside the outside of the corresponding undulating raised edge and presents a fastening end for fastening to the bellows that is situated above the corresponding raised edge.

  • Publication number: 20060138719
    Abstract: A hydraulic antivibration device comprising: two rigid strength members, a working chamber and a compensation chamber communicating with each other via a constricted passage, a decoupling flap being disposed between the two chambers, the flap being movable over a short stroke, at least one perforated rigid partition separating the two chambers, said partition being closed by the flap, the flap being in the form of a plate of elastically deformable material, and being disposed in an opening in a spacer clamped between two plane parallel grids disposed respectively in the working chamber and in the compensation chamber, the stroke of the flap between the grids being defined by the thickness of the spacer.

  • Patent number: 6418582
    Abstract: A bellows for an airplane boarding corridor for passengers, and a corridor including such bellows. A bellows actuator device of the invention has chambers that can be inflated and deflated on command to enable the bellows to be extended and to allow the bellows to be retracted, and it also returns the bellows to the retracted condition. Advantageously, the inflatable chambers of the actuator device of the invention form at least two rows of tubes disposed symmetrically or substantially symmetrically about a longitudinal plane of symmetry of the bellows, each row being individually inflatable. The present invention is mainly applicable to making equipment, in particular weatherproofing bellows, for airport boarding corridors for passengers.

  • Patent number: 4197029
    Abstract: A connector system including a socket with a retaining flange to hold the socket in an opening in one of the parts to be joined. A plug with a longitudinal slot is wedged in an opening of the other part to be joined. A head on the plug coacts with a bayonnet slot opening of the socket to secure the parts together. The wedge for securing the plug can be connected to the plug initially with a break-away connection so the entire plug is a single unit. A disk retained in the socket assists holding the socket in the other part to be joined.
