Abstract
A fin that includes a flared fin body and a strap feature that is configured to wrap around a residual limb or an amputee thereby allowing the amputee to fin kick in an aquatic environment with the fin attached to the residual limb. The strap feature is preferably perpendicular to the elongated direction of the flared fin body and can include multiple band structures along with any number or release mechanisms. The back portion of the fin is open and void of obstruction allowing the residual limb of the amputee to be inserted under the strap feature and with the flared fin body cupping the residual limb.
Claims13
A fin for attaching to a residual limb of an amputee comprising:
- a) a flared fin body;
- and
- b) a perpendicular strap feature that is configured to wrap around the residual limb and secure the flared fin body thereto.
A fin for attaching to a residual limb of an amputee comprising:
- a) a flared fin body that is contoured or curved in the longitudinal direction to cup the residual limb and flares or broadens towards the front end of the flared fin body;
- and
- b) a perpendicular strap feature attached to the flared fin body that is configured to wrap around the residual limb and secure the flared fin body thereto.
A fin for attaching to a residual limb of an amputee comprising:
- a) a flared fin body flared fin body contoured or curved in the longitudinal direction to cup the residual limb and flares or broadens towards the front end of the flared fin body and having a center contoured membrane that is configured to deform when the amputee kicks or strokes the fin in an aquatic environment with the fin attached to the residual limb;
- and
- b) a perpendicular strap feature attached to the flared fin body through slotted apertures, the strap feature being a dual band structure with a two-part clip features that connects a right side of the dual band structure to a left side of the dual band structure and is configured to wrap around the residual limb and secure the flared fin body thereto.
