Abstract: In conventional aircraft cargo compartments panels or similar flat floor elements are fastened to floor beams or similar supporting elements that are installed in the body of the aircraft. Subsequently functional units such as roller elements latches or PDUs are mounted and connected to one another by way of appropriate control conductors. In the present invention it is proposed to fasten the floor elements permanently to the supporting beams so as to form prefabricated floor modules and to install these floor modules in the aircraft.

Abstract: The present invention relates to a lateral guide for guiding cargo items in an aircraft. Such lateral guides are used to guide containers or pallets during their transport from the tail to the nose and to secure them in their final position. The proposed lateral guide has a mounting frame extending in the longitudinal direction and at least one lateral guide device having a sliding carriage, whereby the lateral guide device is movably supported in the mounting frame in the longitudinal direction. The sliding carriage has at least one guide roller for supporting the cargo items.

Abstract: Fastening elements are known in which locking elements can be swivelled out of a non-operative position and into a fixing position. Usually, each of these locking elements has a locking lug. The known fastening devices are mostly very complex in their structure. The some embodiments of present application propose the provision of a fastening device for at least partially securing a first and a second freight item, which fastening device comprises a frame and comprises a locking claw having a first locking lug and a second locking lug. The locking lugs in this case are aligned along a longitudinal direction of the fastening device, for the purpose of encompassing and holding partial portions of the freight items. The locking claws are pivotally fastened to the frame of the fastening device in such a way that the locking claw can be swivelled out of a fixing position, for securing the freight items, into a non-operative position.

Abstract: Cargo hold floors are provided, and comprise panels or similar two-dimensional floor elements for the attachment of roller elements, ball elements, locking bar elements or similar functional elements. Support elements, in particular floor beams, are provided which support the two-dimensional floor elements whereby the floor elements are permanently joined to the support elements to make pre-fabricated floor modules and the floor modules are installable in the aircraft. To make installation work easier, separate load-bearing elements, for supporting the floor modules on and joining the floor modules to a body or a skin of the aircraft, are provided which, before the floor modules are installed in the aircraft, are joinable to the body or skin of the aircraft, and, when the floor modules are installed in the aircraft, are joinable to the support elements. As a result, it is possible in particular cases to make installation significantly easier.

Abstract: A fastening device of a floor module in an aircraft hull is provided. The fastening device comprises an intermediate element that on one hand can be fastened to the aircraft hull using a joining device and on the other comprises a receiving device for a holding portion of the floor module. In this case the fastening device is designed in such a way that mobility of the holding portion relative to the aircraft is guaranteed in the aircraft's longitudinal direction by means of which it is possible to guarantee stress-free installation inside the aircraft hull.

Abstract: Floor modules of a cargo deck in a hull of an aircraft which comprise support devices for carrying functional elements, e.g. panels, roller conveyors or ball mats, are provided. The support devices are attachable in the hull of the aircraft directly or by way of intermediate elements. To improve stability at reduced weight, end support devices, as seen in the aircraft's longitudinal direction, have a thickness reduced in such a way compared to the other support devices of the floor module that only together with the end support devices of a floor module installed adjacently in the hull do they ensure a loading capacity that corresponds to at least the loading capacity of the other support devices.

Abstract: A floor module with roller conveyors which define an aircraft cargo hold floor with a loading level is provided. The floor modules have cross-members to which the roller conveyor is attached. A rail with two side pieces is provided, between which rollers are rotatably mounted in such a way that they protrude above upper edges of the rails. The side pieces are joined to one another by a floor section. To improve the strength of the floor module, the floor section has a bent region inclined in cross-section at an angle to the loading level, the bent region dividing the floor section into one partial section lying higher and one partial section lying lower relative to the upper edges.

Abstract: Roller conveyors of an aircraft cargo deck, including rollers for transporting freight packages, particularly containers, and a channel with side walls and a base for the installation of locking bar elements to hold the freight packages, are provided. The side walls have reinforcing sections with recesses in which the rollers are installed, whereby axles on which the rollers are rotatably mounted are fixed in each of the side walls.

Abstract: Conventional support rollers are installed on the floor of an aircraft cargo hold in a mounting profile that comprises side walls, and in an interior space of the mounting profile latch elements can be mounted in order to secure containers, pallets or similar items of freight. To reduce the construction expense, the weight, and the work of assembly, it is proposed that two external rollers be rotatably mounted, outside the interior space of the mounting profile, on an axle that passes through the side walls of the mounting profile.

Abstract: In aircraft cargo decks are provided to receive loads stored in the cargo compartment (9). The aircraft comprises an outer skin (12) to which ribs (11) are attached. To simplify the construction and the assembly it is proposed that the cargo deck be composed of a plurality of floor modules (20), which are fixed within the cargo compartment (9) and form the cargo deck. To the ribs (11) are attached longitudinal beams (35), on which the floor modules (20) can be mounted.

Abstract: In an aircraft there is customarily provided, for receiving a load in the cargo compartment, a cargo deck that comprises a plurality of ball mats, floor panels or similar flat floor elements. Also provided are a plurality of roller conveyors or similar profile elements mounted in the long direction of the aircraft to accommodate transport rollers, PDUs, latches or similar functional units for moving and fixing the load on the cargo deck.

Abstract: Roller drive units are used for conveying objects, in particular cargo containers, on a roller conveyor track of an aircraft. They comprise a drive motor, a planetary gear with an input connected to the drive motor and with a first as well as a second gear output. A drive roller is connected to the first gear output to propel the object and a lifting apparatus is connected to the second gear output to lift the drive roller out of a retracted resting position, in which the drive roller does not contact the object, into a raised operating position in which the drive roller can engaged with the object. A first brake is provided to slow down the drive roller and a second brake is provided to keep the lifting apparatus in position. To improve the traction characteristics and in particular to improve the force with which the drive roller can press against the object to be conveyed, the first and second brakes are constructed so as to be controllable.
