ABSTRACT:
A foldable leveller leg assembly for supporting an article having a base member directly engaging the article, a leg member pivotally connected to the base member and a foot member adjustably affixed to the leg member. Several means are available for securing the base member to the article. Alternate means may be utilized to lock the leg member in a substantially fixed relationship with respect to the base member so that the leg member can sustain the article when in a vertical position and be folded against it when the article is to be shipped, stored or relocated. The foot member can move independent of a connected stationary element engaging the supporting surface. A roller device associated with the base member enables the article to be moved over a supporting surface when the leg member is in the folded and substantially horizontal position.
