Abstract
The present invention relates to a swimming assistance mechanism and, more specifically, to a swimming assistance mechanism that is attached to the arms and increases a propulsion effect by increasing resistance against water via an action like that of the fins of a fish when paddling with the arms for propulsion, so as to assist in enabling easier swimming. The swimming assistance mechanism of the present invention is characterized by comprising: a main body fixed between the palm and the elbow; and a fin foldably installed on the outer surface of the main body.
Claims7
A swimming assistance mechanism comprising:
- a main body fixed between a palm and an elbow;
- and
- a fin foldably installed on an outer surface of the main body,
- wherein:
- the main body is formed of a synthetic resin material having a strength, and formed at one side thereof with an opening having a length fitted between the palm and the elbow and opened at intervals in a longitudinal direction in which a groove for exposing a base of a thumb is formed at a front palm contact part to which a hand is inserted, and
- the fin is formed of a synthetic fiber, has a U-shape spread outward from the main body except an upper portion on an outer surface of the main body arranged an arm thereon, and is fixed to a plurality of ribs having hinges on an outer periphery of the main body, in which outer ends of the ribs are connected to a plurality of wires wound on a wire winding device at a center of the main body so as to be folded on the outer surface of the main body by elastic force due to wire-winding and unfold while the wires are pulled and released by a water current overcoming the elastic force.
