ABSTRACT OF THE INVENTION The invention is called a "Chainbar" because it may be quickly and easily adjusted to have the characteristics of a flexible chain and/or that of a rigid bar; and may be easily folded into any size rectangular solid of equal volume. It consists of a series of interconnected links, which are flexible like a chain, but have means for restricting the movement between the links, to form a rigid bar. If the Chainbar is in the form of a flexible chain, and is passed through a tube which may be less than one link long, and has proper activating tabs, the movement between links will be sequentially restricted to form a rigid bar, adjustable in one link increments. The Chainbar has ubiquitous uses. It may be anchored at one end and have a device attached to the other end, that may be extended out and away from the anchored end, such as a mirror, microphone, light source, etc. It may be used as folding handles or legs in folding, compact items such as tables, tripods, luggage carriers, etc. It may have hook holes along its bottom edge from which items such as curtains, flags, signs, etc. may be hung. It may also be used in the place of a rigid bar, such as a broom handle, between two supports, etc. 23
