Abstract

There is disclosed herein an frame apparatus for use as a backpack frame in one configuration and as a tent frame in another configuration. The frame members are shaped and sized so as to nest within each other in the backpack configurations. In the tent configuration, six structural elements from the top of the backpack frame are disassembled and then reassembled in the tent frame configuration. Such an arrangement obviates the need for carrying separate frame components for the tent. It also simplifies the process of erecting the tent since one end of the tent is permanently attached to the portion of the backpack which is attached to the portion of the backpack frame which remains unchanged. The tent is simply rolled and the frame members comprising the tent frame are slipped through sleeves formed along the front edge of the tent. In the preferred embodiment the frame members are made of aluminum and slip together without means for fastening one member inside another.
