| (54) | Three-dimensional recreational card |
| (57) A three-dimensional recreational card is formed from a flat card body that is provided
along a circumferential edge with radially spaced slits and between inner ends of
any two adjacent slits with a folding line, so that each folding line and two slits
adjacent to the folding line together define a flap on the card body. The flaps are
alternately bent upward and downward about the folding lines to angularly locate above
and below the flat card body and thereby support a central portion of the card body
over a plane. When the central portion of the card body is subjected to a pressure,
the flaps are partially deformed; and when the pressure is removed, the deformed flaps
generate a restoring elasticity to bounce the whole recreational card off the plane.
When the recreational card rotates in a throwing game, the flaps produce sound due
to a wind shear effect. |
