Abstract
A band includes at least three members pivotably connected to one another so as to be pivotable between open and closed positions. A first member includes first and second permanent magnets disposed at opposite ends thereof, a second member includes a third permanent magnet and a third member includes a fourth permanent magnet. The first and second members are configured such that when they are pivoted with respect to each other past a threshold position toward the closed position, they are biased toward the closed position by forces created by the first and third magnets and when they are pivoted with respect to each other past the threshold position toward the open position, they are biased toward the open position by forces created by the first and third magnets. The first and third members are similarly biased by forces created by the second and fourth magnets.
