Ratchet compressor for expandable luggage

Disclosed is a method and system for compressing and automatically expanding an expandable luggage case 2 comprising a ratchet mechanism 8 and a bungee cord 32 , that is used to bias a locking mechanism, in the form of detents 54 that mate with teeth 44 , in a locked position, and to bias a jack mechanism 14 for automatic expansion. The bungee cord 32 biases the ratchet compressor system 8 in an expanded state. Thus, automatic expansion is achieved, in a very easy to use manner. In addition to being operated while the luggage case 2 is open, the ratchet compressor 8 is also operable from the outside of the luggage case 2 once the luggage case 2 has been packed and closed. A user may then compress the luggage case 2 simply by applying pressure to the lid 24 . The ratchet compressor system 8 therefore provides a zipper-less, automated method of expanding a luggage case 2 as well as compressing the luggage case 2 once the luggage case 2 has been closed.
