Abstract: An apparatus is used for automatic insertion and alignment of freight units, such as pallets or containers, into mobile cargo compartments. The apparatus includes a pivotal guide lever with a hold-down member arranged at an entry guide in the region of an opening into the mobile cargo compartment. For moving the freight into the cargo compartment, the guide lever is displaced by an adjustment lever extending upwardly from the bottom of the cargo compartment. The adjustment lever can be displaced from the path of on-coming freight units so that the freight unit passes over the adjustment lever.

Abstract: The device disclosed is a rapid action clamping element for locking, for example, latch elements to the floor in an aircraft provided with slot tracks. The element includes a base element holding two mushroom headed posts, there being a spring biased cylindrical post in between and a crown ring mounts the base element to the latch housing under determination of the degree of projection of the mushroom headed posts. A two position handle permits spring bias protraction of the cylindrical posts for insertion in one of the apertures in the slot track while permitting retention of a retraction against the spring in the other position.

Abstract: A spring-biased restraining member is retracted by means of a remotely positioned, manually operable lever being outside the cargo space; the linkage includes a hydraulic structure for delayedly returning the lever and the restraining member to the protracted position. The linkage unlocks a latch and enables the cargo to overrun the restraining member even from that side that is to lock the cargo when the restraining member is in its locked position. In the other direction, the restraining member is overridden by the cargo out of each position of the restraining member structure between the lever and the restraining member.

Abstract: A frame structure is fastened to two rails which normally serve in an aircraft for fastening the seating. That frame structure, in turn, holds a frame element to which is mounted a spring-biased latch hook; the frame element can be fastened to the frame structure in different positions, the latter having also a fixed end hook. The structure as a whole establishes a removable YZ restrainer that is readily adaptable to differently wide cargo pallets or the like.

Abstract: A pin extends from the floor near a cargo door and pallets or containers are provided with an attachment which includes a releasable frame with a hinged spring-loaded plate having a bore and runoff surfaces. The bore traps the pin and forces the pallet or container to turn.
