摘要： A hinged mechanism includes: panels; and hinges connecting respective pairs of the panels to each other in a closed loop so that the hinged mechanism is non-planar, wherein at least one of the hinges is a rolling-contact hinge. All of the hinges can be rolling-contact hinges. The closed-loop hinged mechanism can comprise at least four hinges, each of the at least four hinges being a sole connection between a respective adjacent pair of the panels. A cross section of rolling surfaces of the rolling-contact hinge can be circular. A cross section of rolling surfaces of the rolling-contact hinge can be non-circular.

摘要： An apparatus can comprise multiple links, the multiple links comprising at least a first link, a second link, a third link, and a base link, each of the multiple links comprising a rigid sheet, the first link being hingedly coupled to the second link via a first joint, the second link being hingedly coupled to the third link via a second joint, the third link being hingedly coupled to the base link via a third joint, the base link being hingedly coupled to the first link via a fourth joint. The multiple links defining at least a portion of a cylinder when the apparatus is in a stowed position, the first joint, second joint, third joint, and fourth joint being aligned parallel to each other and aligned parallel to a longitudinal axis of the cylinder.
