Abstract
A fin blade for free diving or swimming or scuba diving is described, which has a cross section at one end angled about a yaw, or longitudinal, axis relative to the cross section at the other end. The arrangement is such that a lateral line at a proximal end is disposed at an angle relative to a lateral line at a portion spaced from the proximal end. The fin blade is more closely aligned with the ergonomic complexities of the human body, such that during finning the fin blade provides greater comfort and/or propulsion. A fin blade is also described which includes a reinforced zone in one portion of the fin blade, such that one portion of the blade at the distal end is relatively increased in flexibility to provide a catch zone at one portion of the distal end of the fin blade.
Claims11
A fin blade suitable for free diving, comprising:
- a tongue for connecting a main blade portion to a foot pocket, wherein the main blade portion is planar in shape and is angled downwardly relative to the tongue between 1 and 45 degrees,
- wherein a proximal lateral line extends laterally at a lateral joint between the tongue and the main blade portion, the proximal lateral line adjacent a proximal end of the fin blade is disposed at an angle relative to a lateral line extending across the fin blade at a distal end at a portion spaced from a proximal end of the fin blade, the proximal lateral line at the proximal end of the fin blade is elevated from one side to another side, and the proximal lateral line at the proximal end is elevated from the one side to the other side between 1 and 50 mm.
