Flexible wall section, in particular for heating or refrigerating chambers

Claim 1

A flexible wall section for heating or refrigerating chambers having at least one layer of flexible material with good heat insulating capacity, said wall section comprising: a. coupling means along at least three side edges for fast and releasable interconnection of the section with adjacent wall portions; b. biased pulling members for folding and removing said wall section when said side edges have been released, said pulling members maintaining said wall section in the removed position, c. folding indications perpendicular to the direction of removal so as to facilitate folding of said section during the removing operation, and d. eyelets for each pulling member provided at every second folding indication, said pulling members being attached to the edge parallel with the folding indications and passing through said eyelets, the distance between the folding indications increasing progressively from the lower edge of the section towards the upper edge of the section after each fold so that the upper folds become larger than the lower folds.
