Description

DETAILED DESCRIPTION OF THE INVENTION Background This invention of training for the paddle entitled swimmer of the invention relates to a training device for the swimmer, in particular, to strengthen construction practice, against the stroke movement of the swimmer resistance Training paddles as used to increase the The swimmer is propelled forward by draining water backwards through the movement of its hands and legs. Anyone who wants to have a competitive edge must be directly involved in some form of normal resistance practice. In general, the best training method for sports, especially for enhancing stroke and sustaining power, is the only one achieved by a swimmer using a so-called "hand paddle". Correspondingly, it is not surprising that the body part injured by the competitive swimmer is usually the shoulder. However, the use of paddles results in increased drainage, and this is done by the thrust of each swimming stroke, while each stroke is increased in the tendency of the swimmer's hand to rotate. This habit is even more pronounced when the area is large relative to the size of the hand. The swimmer must counteract this rotational habit to maintain hand stability, while maximizing drainage, which determines the effectiveness of each stroke. Well-known training devices include, for example, hand sized, larger, hand paddles made of rigid plastic material of rectangular or elliptical shape, including a single finger loop (finger). ) And an auxiliary wrist loop (wrist) for securely attaching the hand to this paddle. This example includes a paddle described in U.S. Pat. No. 5,147,233, which is usually in the form of a rectangular, strong, flat plate member, with multiple channels (paths) that directly and temporarily trap water. It has one power surface interwoven with a groove, one surface of which is configured to adhere to the swimmer's hand. The water temporarily caught by the woven surface increases the thrust on each stroke as described above. The swimmer training paddle disclosed in U.S. Patent No. 5,288,254 is generally triangular and has a flat shape with rounded front edges, first and second lateral edges, and a rear edge. One fin is independently provided from the lower surface of the flat plate member, and a means for attaching the middle finger of the swimmer is provided to hold the palm against the upper surface. The hand paddle described in U.S. Pat. No. 4,913,418 is a single, flat, rectangular plastic sheet with rounded corners that is smaller than the size of a human hand. It has a very large surface area. A plurality of openings (holes) are arranged in the paddle surface at a position substantially equal to the size of the user's hand, and are offset in the thumb direction of the paddle. These openings are close to the thumb edge of the paddle, leaving a substantially larger area on the foil side or little finger side of the paddle. However, such swimmer paddles are willing to be used with wide applicability, and this or other prior art designs are rectangular or elliptical in shape and have biceps and tendons (long). Excessive drag in the head muscle) and in the retraction movement (pull phase) early in the freestyle swim cycle, as well as in the sup raspinatus muscle of the rotating cuff (around the arm) I know this empirically. These forces also cause shock syndrome, again contributing to excess stress and damaging the ventral (frontal area) of the shoulder. Accordingly, there is a need for an improved training paddle that enhances stroke strength while minimizing the risk of shoulder damage for swimmers. Thus, one primary object of the present invention is to provide an improved swimming paddle for increasing the strength and endurance of a swimmer without causing excessive drag on the biceps and shoulders of the swimmer. . It is another object of the present invention to provide an improved swimming paddle for reducing the habit of the swimmer turning his hand during a stroke. Another object of the present invention is to reduce the risk of shoulder disorders and enhance stroke power without excessive stress on the acromo- clavicular joint of the acromion and the rotating arm. It is to provide an improved swimming paddle. Yet another object of the present invention is to provide a technique for improving the art of swimmers in water, due to the sensitive changes in water pressure during routine operation of direct strokes in the sensitive palm of the swimmer during the stroke. It is an object of the present invention to provide an improved swimming paddle for developing a proprioceptive sensation responsive to a self-stimulation. SUMMARY OF THE INVENTION Each of these objects is achieved by the present invention as described below. That is, a swimmer training paddle in the shape of a flat mitt (glove), having a surface area larger than the size of the user's hand, with the hand resting on its face with its palm down. . The paddle is constrained by bending to an adjacent edge in conformity with the user's wrist (wrist), and the bent first lateral edge has one of its adjacent edges sharply bent to the distal end. A second lateral edge, which is connected to one end of the edge and also bent, connects the other adjacent edge to the other end of the terminal edge. At a point beyond the tip of the thumb from one end of the adjacent edge, the first lateral edge approaches the outer edge of the thumb, with the palm facing down, and is bent inward to the distal end. Merge with the curvature of the edge. The second lateral edge has a gently curved shape over its entire length, and this constitutes the little finger side edge of the paddle. Also, the foil side of the little finger side edge or paddle is substantially larger than the thumb side. Such paddles typically have a relatively large, irregular opening in the center of their surface area, such that when the hand is positioned on the paddle, it is covered by the most sensitive areas of the palm and fingers. Have one. In addition, a rubber tube (rubber tube) is firmly connected to the paddle by the user's hand with his / her wrist and finger, and is pulled through a hole at an appropriate position. When this paddle is propelled through the water, the user feels the flow of water through its large openings in the palms and fingers, which is the hydraulic pressure that occurs during the stroke necessary to improve underwater swimmer technology. Help develop a sensation that is responsive to self-stimulation for sensitive changes in the body. Also, arranging a plurality of holes in a curved state on a curved row, flowing to the curvature of the little finger side helps to reduce the pressure of the water flow on the little finger side, and this is the surface area of the thumb side Combined with its relatively small size, it reduces excessive pressure around the acromion of the clavicle and the rotating arm. These features reduce the habit of the paddle rotating toward its thumb during a stroke in connection with the angle at which the hand is mounted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT The paddle 10 according to the preferred embodiment of the present invention is comprised of a relatively strong plastic material, preferably polypropylene, which is formed into a very smooth shape without sharp edges. Injection molding (injection molding), the thickness is about 2 mm to 4 mm and the desired flexibility is provided. The paddle 10 is in the form of a flat plate member 11 having an upper surface area in the shape of a mitt or a glove, and has an upper surface area larger than the user's hand 12. The flat member is tied adjacent to the user's wrist by an adjacent edge 13 and has a sharply bent end edge 14, a first lateral edge 15 connecting one end of this edge 14 to the end of the adjacent edge 13, and a bent end. Each end is bent to conform to a second lateral edge 16 connecting the other end of the end edge 14 and the other end of the adjacent edge 13. A portion 15a of the lateral measurement edge 15 approaches a point beyond the tip 12a of the thumb from one end of the adjacent edge 13, and the user's hand 12 is placed in contact with the palm thereof, The first lateral edge 15 is close to the outer edge of the thumb with the palm facing down and bends inward at location 15b, merging with the curvature of the distal edge 14 to form the thumb side of this upper surface. 17 is specified. The other lateral edge 16 has a gently outwardly curved shape and constitutes the little finger edge or top foil side 18 and its surface area is larger than the thumb side 17. In one embodiment, the length of the paddle is measured from the distal edge 15 to the point where the lateral edge 16 connects to the adjacent edge 13 and is approximately 11 inches and the width of the widest point is approximately 81. / 2 inches. This paddle has one large opening 20 of irregular shape, which is usually located approximately in the center of its surface area and is placed on this paddle so as to be covered by fingers and palms. Arranged appropriately. These areas to be covered are the most sensitive to subtle changes in water pressure that occur during repeated stroke operations. The opening 20 is typically in the form of a "keyhole" defined by a single circular opening 20a having a diameter of, for example, 1-5 / 8 inch, and at its widest point, for example, 2-7 / 8 inch. It is interconnected to a crescent-shaped opening 20b, which is 1/4 inch wide and 1/4 inch high, for example, by a rectangular opening 20c 1 inch long and 3/8 inch wide. It has a length of about 4 inches. The crescent-shaped opening 20b is covered by the center of the palm of the average hand 12, and the ring finger and the middle finger cover the circular opening 20a. In addition, the rectangular opening 20c to be connected is covered by a base and a palm portion where the ring finger and the middle finger are connected. The paddle has a plurality of holes 22 which are, for example, 1/4 inch in diameter and eight in number, and are arranged in a curved array such that they begin near the adjacent edge 13 and flow to the gently curving lateral edge 16. They are arranged side by side and result in a terminal edge 14 on the side of the circular opening 20a. In addition, the paddle has two holes 23 provided near the lateral side edge 15 that curves on the opposite side, and four holes 24 near the sharply curved end edge. The hole 23 is disposed immediately on the tip 12a of the thumb, and the hole 24 is disposed beyond the middle finger 12c. These holes 23 and 24 are the same size, for example, 3/16 inch in diameter. The hand is securely attached by a well-known rubber tube (rubber tube) which is appropriately passed through a hole located at a position which is also a reference position of the wrist and each finger and pulled. In particular, as seen in FIGS. 1 and 4, its wrist is securely attached to this paddle by a first piece of rubber tube 26, one end of which is, for example, from three aligned holes 27 near the thumb side edge 15. It is pulled downward through the chosen one and returns from hole 28 to the upper surface along the lower surface of the paddle. The other tube 26 is pulled downward through one of the three holes 29 where the adjacent edge 13 connects to the lateral edge 16 and returns through the hole 25. The position of the user's wrist on the paddle can be adjusted as desired by appropriately selecting a hole to which the tube 26 is to be attached. Also, as seen in FIGS. 1 and 3, the middle finger 12c and the ring finger 12d are held together by the two lengths of the tubes 30 and 31 intersecting each other and are brought into contact with the surface of the paddle 11. Each of these tubes has a corresponding set selected from a plurality of holes opposite the round opening 20a and pulled through each other. More specifically, one end of tube piece 30 is pulled down through hole 32 and returns up through hole 34 along the underside of the paddle, while the other end is down through hole 34. Pulled and comes back through hole 35. Similarly, one end of tube section 31 returns from hole 36 and through hole 37, is pulled down through hole 38 after crossing tube section 30 and returns through hole 39. The set of holes 32 and 38 located on the side of the opening 20 are spaced apart from the set of holes 34 and 36 located on the opposite side by a sufficient distance to comfortably receive the middle and ring fingers of average size. It is provided separately. Both of the intersecting tube pieces can be adjusted to a length that ensures that the fingers are held together and rest on the top surface of the paddle. The tube pieces are also positioned relative to the wrist strap 26 such that the middle finger 12c is oriented substantially centrally of the four holes 24 with its tip facing the distal edge 14. In use, the swimmer slides the hand 12 into this wrist tubing site (wrist strap) 26 and under the cross tubing sites (cross tubes) 30 and 31 until the strap fits substantially near the base of the finger. Put your middle finger and ring finger in. These tubing sites are then pulled further through the corresponding holes for adjustment until the hand is firmly seated on the paddle surface. In the surface area of this paddle, the hand is attached to the center, the middle finger and the ring finger are firmly placed in such a manner that the thumb side 12a naturally faces the direction of the hole 23, and the index finger 12b has the curved edge 15a. , And the little finger 12 e extends toward the lateral edge 17. This hand with its fingers spread out and smaller than the size of the paddle, but almost the same size, and this paddle is also similar in shape to the hand except for the foil (cut) shape on the little finger side Has formed. And this contributes to the stability of the paddle against possible thumb rotation, which can occur with all commercially available paddles. The foil shape also gives the swimmer the power to lift with his own hands during training, the so-called “lift force”. In the practice of swimming strokes, for example in the case of freestyle or crawl, such paddles are best suited for them, the swimmer first reaching out his hand, carefully lifting his elbow, and It is driven forward when the attached paddle enters the water surface. This mitt-shaped configuration of the rounded distal edge 14 and the paddle acts separately and interacts to slice the water surface with minimal turbulence. While penetrating the surface of the water, the hand and paddle are rotated in a relationship parallel to the surface and continue to be driven rearward to achieve a playing motion. This watering movement should continue for a certain distance beyond the reach of the one-arm stroke, and is due to the extra force acting to drive the swimmer's body movement partially obtained from the preceding stroke forward. It is possible. The paddle should also be maintained approximately parallel to the water surface to achieve optimal lift. When the hand and arm to which the paddle is attached are driven down and back during the stroke, the angle attached to the paddle surface by the crossed finger straps 30 and 31 depends on the propensity of the rotating paddle to move toward the thumb. (Habits) are reduced. This is common with paddles of the design taught, for example, in the aforementioned U.S. Pat. No. 4,913,418, which causes the stroke to fail. If the swimmer does not drive this paddle and hand backwards towards the end of the stroke, and does so slightly upwards until they reach the surface of the water, the swimmer will slow down and move forward. Pushes the water between the paddle and the hand, and tends to tear the paddle away from the hand. Thus, the roll (roll), pitch (pitch) and yaw (yaw) of the paddle must be controlled throughout the stroke in order to work smoothly. If the paddle experiences turbulence or agitation, or shows a tendency for the paddle to be withdrawn from the hand, the paddle is not communicating well with the swimmer in the effects of the stroke. The paddle of the present invention enhances the above communication by significant water flow through the large opening 20 provided when the paddle is driven underwater during repeated strokes. The so-called "obstacle" to the sensitive palm area, where significant water flow passes through its shaped opening, increases the development of sensitively sensing the subtle changes in water pressure that occur during a stroke, making it most effective. It allows the paddle to behave in the right way, and tells swimmers their correct position when swimming with bare hands without using this paddle. Limiting the surface area of the paddle between the thumb and the index finger limits limiting the damage to the deltoid muscles and tendons. Also, stabilization of the rotating cuff (around the arm) and pseudo muscles is effectively achieved due to the large surface area on the outside of the hand (ie, on the side of the paddle). On the other hand, a large lift force generated at the gentle outer edge of the cut shape on the little finger side is counterbalanced and attenuated by the water flow through the opening 22 supplied along this edge. It should be noted that the improved swimmer handpaddle described in detail above has been considered based solely on the preferred embodiment shown in the drawings, but those skilled in the art will appreciate that There will be a possibility of various other modifications without departing from the scope of the present invention. For example, the opening 20 may be shaped differently for a useful effect in use, and when considered, will feel the flow of water through this opening and will most likely experience subtle changes in water pressure. It is provided on a paddle corresponding to the area and its vicinity, and is arranged at a position to be covered by the area. Of course, the size and arrangement of the plurality of holes 22, 23, 24 may be variously modified based on their use. Further, although two fingers are placed in contact with each other as illustrated here, the finger straps (finger straps) may be modified to receive three or four fingers. Also, the paddle may be manufactured for each size to accommodate changes in hand size, or may be made of other materials. Accordingly, the gist of the present invention should be determined by reference to the appended claims, and not by the examples disclosed herein.
