The invention relates to an expansion device for an article with an expandable, at least two lateral surfaces comprehensive coat. The object is in its unfolded and / or expanded state of use z. B. is a presentation rack, in particular a presentation column, a table or floor display, a Wölbesäule, a decorative column, a presentation stand, a table or stand or the like. The widening device serves, in particular, to unfold the sheath from a first state (eg essentially flat state, in particular transport or storage state) in a self-unfolding and / or automatically to a second state (eg expanded use state).

From the prior art selbstentfaltbare by means of Aufweitkörpern presentation columns of cardboard or cardboard blanks in a variety of embodiments are known. The presentation columns usually comprise an expandable jacket with two lateral surfaces. The jacket can be made of a one-piece blank and be formed by being folded over at one edge region and at the other edge region, the two lateral surfaces are fastened together. The disadvantage of this is z. Example, that the two lateral surfaces thus rigidly connected to each other and / or are designed to be immovable relative to each other, which unwanted deformations, tensions and / or crushing deformations can occur, especially when the jacket is unfolded and / or collapsed.
