Ratchet compressor for expandable luggage

Disclosed is a method and system for compressing and automatically expanding an expandable luggage case comprising a ratchet mechanism and a bungee cord , that is used to bias a locking mechanism, in the form of detents that mate with teeth , in a locked position, and to bias a jack mechanism for automatic expansion. The bungee cord biases the ratchet compressor system 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 is open, the ratchet compressor is also operable from the outside of the luggage case once the luggage case has been packed and closed. A user may then compress the luggage case simply by applying pressure to the lid . The ratchet compressor system therefore provides a zipper-less, automated method of expanding a luggage case as well as compressing the luggage case once the luggage case has been closed.
