Abstract

  A long and thin elastic member provided on the back surface of the swimmer's forearm with the first and second ends facing each other, and a first attachment for mounting the first end on the tip of the swimmer's hand or wrist near the wrist A tool used during swimming having means and second attachment means for attaching the second end to the middle part of the arm near the elbow of the swimmer. The tool vibrates and creates a vortex on the back side of the forearm, allowing the swimmer to modify its stroke to maximize the generated vortex and facilitate the correct stroke technique.

Description

  The present invention relates to a tool used when swimming, for example, as a coaching or training aid.

  Many tools used during swimming have been developed, including tools used to help improve swimming stroke technology. One such tool is a hand paddle, which is mounted on a swimmer's hand and has a flat surface that extends over the palm and fingers of the swimmer. According to this tool, the surface area of the hand increases and the propulsive force of the stroke increases.

  However, this tool has the disadvantage of bending the elbow or wrist to reduce stroke force and promote an unfavorable form. Furthermore, this tool invites strokes that make the swimmer feel a different swimming rhythm compared to swimming without paddles. Also, when used in swimming strokes other than freestyle, it is actually in the way.

  A first aspect of the present invention comprises an elongated elastic member having opposing first and second ends and provided on the back of the forearm of a swimmer's arm, and the first end near the swimmer's hand or wrist There is provided a tool used during swimming having first mounting means for mounting on the tip of the arm and second mounting means for mounting the second end on the middle part of the arm near the swimmer's elbow.

  Preferably, the first mounting means includes a biasing means for mounting the first end portion on a hand near a swimmer's finger joint and biasing the hand so that the hand bends outward from the forearm at the wrist portion. Supply.

  Preferably, the tool further comprises one or more spacer members positioned between the elongate elastic member and the back of the forearm and maintaining a gap between the elongate elastic member and the back of the forearm.

  The first mounting means or the second mounting means may be a loop made of an elastic material. Preferably, the elastic member is in the form of an infinite loop in which the first mounting means and the second mounting means are integrally formed at each end.

1 is a perspective view of a preferred embodiment of the present invention. FIG. 2 is a view of the tool of FIG. 1 provided on the forearm. FIG. 3 is a side view of the tool shown in FIG. 2.

  In a preferred embodiment of the present invention, the tool used during swimming as illustrated in FIG. 1 is composed of one or more rubber, elastic tubes.

  The rubber tube is an elastic member 2 provided on the back surface of the swimmer's forearm as illustrated in FIG. 2, and includes a first end portion 4 and a second end portion 6. This first end 4 is coupled to the first mounting means 8 in the form of a loop of elastic material. The loop 8 is formed of the same material as the elastic member 2. Similarly, the second end 6 is attached to a rubber loop 10 constituting the second attachment means. The first mounting means 8 and the second mounting means 10 are formed integrally with the elastic member 2 and constitute an infinite loop.

  Between the loop 8 and the first end 4 and between the loop 10 and the second end 6, a spacer member 12 is provided in the form of one or more small rubber pads. With these pads 12, the elastic member 2 can be separated from the swimmer's forearm as illustrated in FIG. For this reason, the elastic member 2 can vibrate more freely when the forearm supporting the tool operates in water.

  A preferred embodiment of the present invention is provided by a swimmer who hooks a rubber loop 10 around the elbow of the swimmer and a rubber loop 8 around the finger so that the elastic member 2 extends along the back of the forearm of the swimmer. used. The rubber loop 8 is mounted around the swimmer's finger near the swimmer's finger joint.

  The action will be described. When the swimmer performs a normal swimming stroke, the elongate member is vibrated by the water flowing across the swimmer's forearm and the vortex on the back side of the forearm is increased. A swimmer can feel this vortex and modify its stroke to maximize the generated vortex. This tool also serves to provide a biasing force that biases the swimmer's hand to bend backwards toward the outward forearm at the wrist. In order to maintain the proper form (and thereby maximize the vortex), the swimmer must act against this biasing force, thus assisting the proper wrist posture for the stroke it can.

  The preferred embodiment of the present invention provides the following advantages, among others.

  (A) The swimmer's wrist posture is controlled so as not to adversely affect the stroke technique.

  (B) The correct stroke technique is promoted without disturbing the stroke flow.

  (C) By using this tool, the swimmer can exert more energy, promote the force of the propulsion muscle, and adjust the swimmer's cardiovascular system.

  As used throughout this specification, the term “consisting” and its derivatives, “having (plural)” or “comprising” are used to describe the element, integer value, step, or element being described. It should be construed to include numerical values and process groups, and is not meant to exclude other elements, integer values, processes, or element groups, integer values, process groups.

  The discussion of documents, operations, materials, devices, products, etc. included herein is provided solely for the purpose of illustrating the present invention. Any one or all of these may form part of the prior art base or be common in the field relevant to the present invention as they existed in Australia or elsewhere before the claim date of each claim of this application. It does not certify that it was general knowledge.

  It will be appreciated by those skilled in the art that various modifications and / or changes can be made as broadly described for the invention shown in the specific embodiment without departing from the spirit or scope of the invention. Is. For example, the mounting means can be made of a material different from that of the elongated member. Thus, this example is to be construed in all respects as being exemplified and not limited thereto.
