A folding fan 10, for use in throwing or juggling, comprises at least two ribs 20, each rib comprising a hole at a first end region thereof, a leaf 30 which at least partially covers and is fixed to the at least two ribs such that it extends across, or at least partially covers, a second, opposite, end region of the at least two ribs, and a pivoting portion at the end of the fan that accommodates the first end regions, wherein the pivoting portion comprises a pivot member 60 that passes through the holes in the ribs, about which the ribs can pivot or rotate for opening and closing the fan. In a closed condition of the fan, the fan has fan length (l, Fig 8) with two halves, one occupying the first end regions of the at least two ribs (44, Fig 8) and the other occupying the second, opposite, end regions of the at least two ribs (43, Fig 8); and a balance point of the fan lies along that length in the half of the fan length that is occupied by the first end regions of the ribs. In order to achieve this, the pivoting portion may be provided with at least one weighted component (28, Fig 6); for example a weighted disk like spacer (or washer). |
