Abstract

A swimming aid apparatus includes a foot-mounted swim fin, such as those used by scuba divers and snorkelers. An improved foot-mounted swim fin with a lower leg binding provides greater thrust for the user whilst lowering the strain normally imposed upon the ankle joint in use.

Claims (18)

1. A swim fin device comprising:
a) a fin member consisting of a webbed member and a foot-receiving portion affixed to the webbed member;
b) a shin member having shin attachment means for attachment to a lower leg;
and c) a connecting member, connecting the webbed member to a central portion of the shin attachment member; wherein the webbed member extends a maximum of about 180o from a user's tibia.
2. The swim fin device of claim 1, wherein a first end of the connecting member is pivotally attached to a top surface of the fin member; and a second end of the connecting member is pivotally and slidingly engaged with a central portion of the shin member.
3. The swim fin device of claim 2 or 3, wherein the first end of the connecting member is removably attached to the fin member.
4. The swim fin device of any one of claims 1 to 4, wherein a hinge is used to attach the first end of the connecting member to the fin member.
5. The swim fin device of claim 1, wherein the connecting member consists of a plurality of inter-linked members.
6. The swim fin device of any one of claims 1 to 5, wherein the webbed member and foot-receiving portion are formed as a single piece.
7. The swim fin device of any one of claims 1 to 6, wherein the shin member comprises padding on an inner surface thereof.
8. The swim fin device of any one of claims 1 to 7, wherein the foot-receiving portion is secured to a user's foot or ankle.
9. A swim fin device comprising:
a) a fin member consisting of a webbed member and a foot-receiving portion affixed to the webbed member;
b) a shin member having shin attachment means for attachment to a lower leg;
and c) a connecting member for connecting the webbed member to the shin member;
wherein a first end of the connecting member is pivotally attached to a top surface of the fin member; and a second end of the connecting member is pivotally and slidingly engaged with a central portion of the shin member.
10. The swim fin device of claim 9, wherein the second end of the connecting member includes a pivot means that engages with a first pair of longitudinal slots in the shin member, and the connecting member engages with a third longitudinal slot in the shin member.
11. The swim fin device of claim 9 or 10, wherein the first end of the connecting member is removably attached to the fin member.
12. The swim fin device of any one of claims 9 to 11, wherein a hinge is used to attach the first end of the connecting member to the fin member.
13. The swim fin device of any one of claims 9 to 12, wherein the webbed member and foot-receiving portion are formed as a single piece.
14. The swim fin device of any one of claims 9 to 13, wherein the webbed member extends to a maximum angle of about 180o from the user's tibia.
15. The swim fin device of any one of claims 9 to 14, wherein the shin member comprises padding on an inner surface thereof.
16 16. The swim fin device of any one of claims 9 to 15, wherein the shin member is made of a material that is lightweight, rigid and waterproof.
17. The swim fin device of claim 16, wherein the material is selected from the group consisting of aluminum, plastic, carbon fibre and stainless steel.
18. The swim fin device of any one of claims 9 to 17, wherein the foot-receiving portion is secured to a user's foot or ankle.
