Abstract

A locking device for securing a piece of freight to a loading floor, especially in an aircraft in which a floor separates an upper deck from a freight space below the deck, is equipped with an adjustable locking mechanism at each end of the locking device. With the locking mechanism, it is possible to secure the locking device to support rails in the loading floor and to also adjust the position of the locking device relative to a neighboring locking device. For this purpose, each locking mechanism is equipped, at each end of each locking device frame, with two teeth plates, one of which is forming a locking end plate at an end of the locking device frame, while the other plate is part of a clamping system relative to which the frame of the locking device can be shifted within certain limits determined by the length of an elongated hole in each locking end plate. Once the locking device is in the desired position, which is indicated by a scale and a marker, the clamping system is secured by tightening nuts on two clamping bolts. Thus, it is possible to adjust each locking device with due regard to the requirements of the piece of freight that is to be tied down.
