Abstract
A dunnage device is disclosed. The dunnage device includes a mounting plate to secure the device to a trailer. The dunnage device is supported in a raised position by a first and second support plate. The dunnage device is configured to bear a load in the raised position by a load supporting plate connected to the first and second support plates. The dunnage device is able to transition between the raised position to a lowered position with a reduced profile. The translation of the dunnage device occurs by one or more pivotable connections.

A dunnage device, comprising:
- a mounting plate configured to mount to a trailer;
- a first support plate connected to the mounting plate by a first pivotable connection between the mounting plate and the first support plate;
- a load supporting plate connected to the first support plate by a second pivotable connection between the load supporting plate and the first support plate, the load supporting plate configured to support a load;
- a second support plate connected to the load supporting plate by a third pivotable connection between the second support plate and the load supporting plate;
- the dunnage device configurable between a raised position and a lowered position by the first pivotable connection, the second pivotable connection, and the third pivotable connection;
- and
- a locking plate, wherein the dunnage device is held in the raised position by contact between a side surface of the locking plate and the second support plate;
- wherein the dunnage device is configured to provide a space between a top surface of the trailer and a bottom surface of the load when in the raised position.
