Abstract
A locking flange (200) for securing an airline cart (100) can include a hook shaped flange that wraps around a pull bar (130) of the airline cart, a pair of apertures (204) on opposing sides of the hook shaped flange where the apertures reside below the pull bar when the hook shaped flange is placed on top of the pull bar, and a locking mechanism (250) for insertion within the apertures once the flange is placed on top of the pull bar. The locking flange can project below a top plane of a door (102) of the airline cart. The locking flange can be made of metal such as high tensile steel. The locking mechanism can include a cylinder having a head (252) on one side and an aperture (256) on an opposing side for placement of a lock (502) through the aperture of the cylinder.
