Abstract
A multi-part diving fin includes a blade portion having a tip and a shoe end opposite the tip, the shoe end at least partially defining a foot pocket, and a foot plate formed as a separate piece from the blade portion and having a formation for releasably engaging the blade portion, the foot plate configured so that upon engagement with the blade portion, the foot plate provides a bottom of the foot pocket. The present fin also features a vertical adjustment of the height of the foot pocket, as well as stiffness adjustment for the blade portion of the fin.
Claims30
A multi-part diving fin, comprising:
- a blade portion having a tip and a shoe end opposite said tip, said shoe end at least partially defining a foot pocket;
- a foot plate formed as a separate piece from said blade portion and having a formation for engaging said blade portion, said foot plate configured so that upon engagement with said blade portion, said foot plate provides at least a portion of a bottom of said foot pocket;
- said blade portion has a slot and said foot plate has a first end having a tab constructed and arranged to engage said slot;
- and
- said foot plate is pivotable in a vertical plane parallel to the longitudinal axis of said blade portion, said tab defining the pivot point.
A swimming fin comprising:
- a blade portion and a separate foot plate, the blade portion having a longitudinal axis, two side edges and a knobbed stub shaft projecting from each side generally normally to said axis;
- a bracket projecting from at least one side of said foot plate and having at least two vertically spaced openings, said openings being constructed and arranged on said foot plate so that vertical adjustment of said foot plate relative to said blade portion is achieved by insertion of said stub shaft into a corresponding one of said openings.
A stiffness adjustment for a diving fin having a blade portion with a tip and a shoe end opposite the tip, said blade portion having a longitudinal axis, and a foot plate separate from said blade portion, said stiffness adjustment comprising:
- at least one stiffness rod located on said foot plate so as to engage a corresponding tube on said blade portion, the stiffness of said blade portion increasing with the distance of penetration of said rods in said tube.
A diving fin, comprising:
- a blade portion having a tip, an upper surface, a lower surface, at least one open topped stiffness recess on said upper surface, and at least one stiffness adjusting insert configured to be secured in a corresponding one of said recesses, said recess configured to receive said stiffener in a direction normal to said upper surface.
A multi-part diving fin, comprising:
- a blade portion having a tip and a shoe end opposite said tip, said shoe end at least partially defining a foot pocket;
- a foot plate formed as a separate piece from said blade portion and having a formation for engaging said blade portion, said foot plate configured so that upon engagement with said blade portion, said foot plate provides at least a portion of a bottom of said foot pocket;
- said foot plate includes at least one blade stiffening formation configured for engagement with corresponding formations on said blade portion.
A multi-part diving fin, comprising:
- a blade portion having a tip and a shoe end opposite said tip, said shoe end at least partially defining a foot pocket;
- a foot plate formed as a separate piece from said blade portion and having a formation for engaging said blade portion, said foot plate configured so that upon engagement with said blade portion, said foot plate provides at least a portion of a bottom of said foot pocket;
- said foot plate is provided with a first end for engaging said blade portion and a second end being adjacent said shoe end;
- said first end of said foot plate has at least one mounting formation for attachment to said blade portion, said at least one mounting formation is a tab configured for abutting an underside of said blade portion, and further including a retainer plate configured for being fastened to said tab through at least one corresponding opening in said blade portion.
A multi-part diving fin, comprising:
- a blade portion having a tip and a shoe end opposite said tip, said shoe end at least partially defining a foot pocket;
- and
- a foot plate formed as a separate piece from said blade portion and having a formation for engaging said blade portion;
- said foot plate includes an upper shell half and a lower shell half hinged together at a front end of each half to form said bottom of said foot pocket, said upper shell half configured for alignment with and attachment to an underside of said shoe end.
