发明名称 Dual mode swim fin
摘要 A swim fin for use in a swimming mode and in a walking mode has a boot portion including a shoe having a foot receiving pocket and a bulbous connecting member. Three tracks are formed in the connecting member terminating in a cavity at each end of each track, the cavity at one end being disposed substantially parallel to the axis of elongation of the foot receiving pocket and thus the foot of a swimmer and the cavity at the other end of each track being disposed approximately 90 degrees to the axis of the foot receiving pocket. The fin also includes a web having fingers adapted to be received in the cavities at one end of the tracks or in the cavities at the other end of the tracks selectively when the web is positioned in the swimming mode or the walking mode. The web also carries pins which are resiliently connected to the boot portion of the fin and positioned within a guideway in the connecting member. The configuration of the guideway is such as to urge the fingers into one or the other sets of cavities. The fingers may be positioned in one set or the other of the cavities by pulling the web to remove the fingers from one set of the cavities and repositioning the web with the fingers positioned in the other set of cavities.
