  • Patent number: 7258406
    Abstract: A suspension device for a lowerable luggage stowage compartment has at least one spring element for assisting the movement of the compartment into a closed position against the force of gravity, and at least one damping element for damping the movement of the compartment into an opened position. A weight detector detects the weight of the compartment, and at least one additional spring element can be actuated based on the detected weight of the compartment. A retention device is provided for fixing the additional spring element. The suspension device provides a compartment that is easy to handle and easy to close even when fully loaded.

  • Patent number: 7097138
    Abstract: The invention relates to an overhead luggage container (1), particularly for airlines, comprising a reinforcing structure (11) which is connected to the container (1) and which is disposed essentially in the direction of the longitudinal extension of the container (1), and at least one device (5) for suspension on a carrying structure (2) of the plane. In order to create a container (1) which can be subjected to relatively high static strain without running the risk that the container (1) will fall on the passengers sitting below, while at the same time reducing technical complexity in production and reducing the weight of the container, at least one respective rigid connecting element (17) is arranged to the side of the container (1) between the reinforcing structure (11) and the suspension device (5) in a substantially vertical manner with respect to the longitudinal extension of the container (1).

  • Patent number: 7011276
    Abstract: A carrying or guiding device for aircraft components, in particular for landing flaps arranged on an aircraft wing, including a carrier having a substantially U-shaped section with substantially parallel side walls, and a cover plate arranged at the open side. To minimize weight, facilitate manufacture and mounting, and provide sufficient strength, the carrier and the cover plate are made of fiber reinforced plastic, in particular of carbon fiber (CF) reinforced plastic. The connection between the carrier and the cover plate and any possible connecting elements is preferably provided by gluing and, possibly, by additional rivet or screw connections.

  • Publication number: 20040245897
    Abstract: The invention relates to a suspension device for lowerable luggage stowage compartments (21) comprising at least one spring element (1) for assisting the movement of the compartment (21) into its closed position contrary to gravity, and at least one damping element (2) for damping the movement of the compartment (21) into its opened position, and comprising a means for detecting the weight of the compartment (21) and at least one additional spring element (25) capable of being activated or switched over in dependence on the detected weight of the compartment (21), a retention device (13, 36) being provided for fixing the at least one additional spring element (25), as well as to a lowerable luggage stowage compartment (21) comprising such a suspension device.

  • Patent number: 4106796
    Abstract: A connector for a low-temperature-fluid duct comprises male and female connector members which interfit and, like the duct portions to which they are connected, have respective coaxial nested pipes including a first pipe forming a central flow passage for the deep-cooled medium, a second pipe defining with the first pipe a flow passage for a mixture of liquid and gaseous phases of this medium, a third pipe defining with the second pipe an inner vacuum chamber, a fourth pipe defining with the third pipe another flow passage for the medium, usually in a gaseous state, a fifth pipe defining with the fourth pipe an outer vacuum chamber, etc. According to the invention, the vacuum chambers of each connector member are sealed at the ends of the respective pipes and overlap the interfitting parts of the respective flow passages.
