ABSTRACT:
An apparatus for insertion into and expansion of a soft bag or backpack, having a relatively flat foldable member, which is connected to a resilient member or an actuating mechanism. The flat member is folded along at least one transverse axis into at least two sections. The resilient member is connected to the opposed ends of the flat member and urges the ends of the flat member inward from its flat position to a folded position. In the folded position, the flat member forms a gable and pushes the sides of the bag outward to expand the bag. In another form, a cord is used to pull the apparatus into its bag expanding position. Relatively flat inserts may be added to promote uniform expansion of the bag.
