Abstract: A movable cargo support for an aircraft cargo hold or passenger cabin includes a base member with its bottom surface having one or more support sections to support the base member on a floor surface. The base member includes wheel assemblies having a wheel member rotatable about a rotation axis and movably mounted on the base member to pivot about a steering axis of the wheel assembly and which can be altered between an extended position where the wheel member protrudes beyond the support plane and a retracted position where the wheel member does not extend beyond the support plane.

Abstract: A method for joining two substantially planar fiber-composite structural components, includes stacking the two components on a support jig to overlap along a joining region. A lower component end section within the joining region borders a gap between the upper component and the jig, where the upper component is unsupported by the jig. The gap is bordered on an opposite side of the lower component end section by a filling portion of the upper component or a planar filler element supported by the jig. The lower component is joined to the upper component within the joining region by applying temperature and pressure to the components. A width of the gap allows the upper component to elastically deform along the gap under the pressure and bend down into the gap to abut the jig along the gap and thereby compensate thickness tolerances between the components during the pressure application.

Abstract: A blocking mechanism which is integrated with a threaded fastener is proposed for improving the reusability and handling of locking devices for threaded fasteners, such as threaded bolts or nuts. The blocking mechanism can be switched to and from between a blocked state, in which the threaded fastener is gripped in a positively locking manner, and an unblocked state, in which the threaded fastener can be rotated. The blocking mechanism can have a blocking element which can engage into a blocking groove of the threaded fastener in a positively locking manner in the blocked state, and thus prevents rotation. For example, a nut which is provided with the blocking mechanism can be used to pivotably fasten a fastening rod to a fastening rail.
