Patent ID: 6866237

Claim:
A support assembly for stably retaining a print medium in position on a generally horizontal surface, and comprising: at least one pair of magnetically couplable support elements sized and shaped for magnetic coupling to each other through the print medium so that the elements are supported by the generally horizontal surface and provide a supportive base thereon for the print medium, at least one of said support elements being formed from a pair of mating body portions of magnetically non-responsive material having respective interior and exterior wall surfaces and a respective mating face extending therebetween, said faces mating with each other along at least one seam to form a generally hollow shell defined by said interior and exterior wall surfaces. each of the mating body portions having an open-ended, generally cylindrical wall extending inwardly from its interior wall towards and beyond its mating face, the respective sizes and positions of the generally cylindrical walls being such that the inwardly-extending cylindrical wall of one of the body portions forms a generally enclosed space within the support element in cooperation with the inwardly-extending generally cylindrical wall of the other body portion when the two body portions are mated to form the support element; and a magnet having a north pole and a south pole and positioned within the generally enclosed space, said magnet being sized to move freely within the generally enclosed space so that either of said poles can generally abut an interior wall surface of either body portion.
