Description

Technology Field

[0001] The present invention relates to a tennis racket swing aid, and more specifically, to a tennis racket swing aid that allows a swing to be performed while wearing a swing aid capable of distributing the weight of the tennis racket, thereby enabling children, women, and the elderly with weak arm strength to receive tennis lessons or play matches without feeling burdened by the weight of the racket. Background Technology

[0002] Tennis is a game played by hitting a soft tennis ball with a racket and sending it over to the opponent's court.

[0003] Tennis is known to have originated in the Middle Ages and is one of the popular sports widely played around the world.

[0004] In addition, many tennis clubs are active in Korea.

[0005] A racket used in a tennis match is composed of, as illustrated in FIG. 1, an elliptical head portion (101), a string (101a) that is connected to the head portion (101) in a grid pattern, a neck portion (102) that extends to one side from the head portion (101), and a handle portion (103) that has a polygonal cross-section and is used for a user to grip with their hand.

[0006] However, tennis rackets weigh about 250 to 350 pounds and are large, so it is not easy for children or women with weak arm strength to swing them.

[0007] As a result, it is difficult for young people with weak arm strength to learn tennis early, even if they want to.

[0008] In addition, even those who have played tennis for a long time find it difficult to execute accurate swing motions as they get older because their arm strength weakens.

[0009] In addition, tennis requires learning various stances such as slices, volleys, racking, and cocking, but if you feel burdened by the weight of the racket, it becomes difficult to accurately master these movements.

[0010] In addition, if you continue to perform incorrect swing motions while your arm strength is weakened, the likelihood of developing so-called "Take's Elbow" increases.

[0011] Meanwhile, a search for prior art related to the present invention resulted in the discovery of numerous documents, some of which are introduced below.

[0012] Patent Document 1 relates to an educational tennis racket that improves the recognition of grip positions, comprising: a main body including a racket frame and a handle extending from the bottom of the racket frame and having a plurality of faces in a polygonal column shape; a first indicator attached to the front of the handle having a first color for guiding the forehand grip position; and a second indicator having a second color different from the first color for guiding the backhand grip position, each attached to either an adjacent face adjacent to the front or a right face adjacent to the front and a face opposite to the front, respectively, according to the user's handedness.

[0013] According to Patent Document 1, by configuring a marking section with clearly distinguished functions and positions on each side of the handle, the forehand and backhand grips are structurally separated to provide visual guidance, and in particular, the grip position automatically corresponds to the direction of the user's dominant hand, thereby enabling beginners or youth to quickly acquire the correct grip position.

[0014] Patent Document 2 relates to a tennis racket for swing practice, and has the advantage of being able to correct incorrect posture during swing practice by notifying the user through a display unit installed on the handle only when the tennis ball is accurately hit in the correct position of the head, as well as being easy to disassemble and assemble by dividing the tennis racket for swing practice into three parts, and convenient to store and carry because the connecting member can be stored inside the handle.

[0015] Patent Document 3 relates to a tennis racket that can significantly reduce the twisting of the racket that may occur when striking a tennis ball, absorb shock and vibration generated during the process of striking the ball to provide stability, prevent physical injury to the user, and facilitate control of the tennis racket; the tennis racket comprises a head that can strike a tennis ball by binding strings in a grid pattern to an elliptical frame, a neck portion connected downward from the axis center of the head, and a shaft having a handle that the user can hold with their hand downward from the neck portion; a shock absorption means for absorbing and mitigating shock and vibration generated when striking a tennis ball on the frame and the neck portion; and a balancer for maintaining the balance of the racket at the boundary position between the neck portion and the handle constituting the shaft to increase centripetal force and increase swing speed.

[0016] However, the aforementioned prior art does not consider a method of distributing the weight of the tennis racket to enable a swing motion with less force.

[0017] Although the weight of tennis rackets has recently decreased due to the use of lightweight materials, the weight of the racket remains a burden for female youth tennis players. Prior art literature

[0045] A preferred embodiment of the present invention will be described in detail below with reference to the attached drawings.

[0046] A swing aid for a tennis racket according to the present invention, as illustrated in FIGS. 2 and 3, comprises a head portion (101) in which strings (101a) are bound in a grid shape, a neck portion (102) extending to one side from the head portion (101), and a handle portion (103) for a user to grip. In this swing aid for a tennis racket, the handle portion (103) of the tennis racket and a support member (30) worn on the user's wrist are connected to each other by a connecting member (10) made of an elastic material.

[0047] This distributes the weight of the tennis racket to the user's wrist during the swing motion, significantly reducing the perceived weight of the racket.

[0048] Here, the connecting member (10) is preferably formed as a rubber band with a diameter of 2 to 4 mm, but is not limited thereto. The connecting member may be formed in the form of a rubber band rather than a circular rubber band.

[0049] And the above connecting member (10) is configured to include a handle ring (10a) that wraps around the racket handle portion (103) as shown in FIGS. 4 to 6, and a fixing ring (10b) that is stretched toward the user's wrist and hooked onto a support member (30) worn on the wrist.

[0050] Additionally, a binding portion (10c) tied with a string may be further formed at the boundary between the handle ring (10a) and the fixing ring (10b) of the connecting member (10).

[0051] By means of the above binding part (10c), only the fixing ring (10b) can be passed through the through hole (20a) of the fixing band (20) to easily tension it.

[0052] Meanwhile, if a reinforcing protrusion (20b) is formed on the connecting member (10), the binding part (10c) may be omitted.

[0053] And the handle ring (10a) of the above connecting member (10) is fixed to the outer surface of the handle portion (103) so as not to be exposed to the outside by a ring-shaped fixing band (20) having a certain width.

[0054] The above fixing band (20) is preferably provided as a rubber band, but is not limited thereto.

[0055] In addition, the above fixing band (20) is provided with a through hole (20a) in the upper center so that the fixing ring (10b) of the connecting member (10) passes through the through hole (20a) and then gets caught on the protrusion (32) of the supporting member (30).

[0056] In addition, a reinforcing protrusion (20b) including a through hole (20a) may be formed at the upper center of the fixed band (20).

[0057] In addition, the through hole (20b) can be prevented from being damaged by the reinforcing protrusion (20b) mentioned above.

[0058] In addition, the fixing band (20) prevents the handle ring (10a) from moving during a swing motion by wrapping the handle ring (10a) from the outside and fixing it to the handle part (103).

[0059] Thus, even if the user performs a strong smash, the handle ring (10a) does not come down.

[0060] In addition, the support member (30) is configured to include an arc-shaped body part (31) formed of a flexible plastic material as shown in FIGS. 7 to 9, a protrusion (32) provided on the outer surface of the body part (31) to allow the fixing ring (10b) of the connecting member (10) to be tensioned and caught, and a support band (33) for fixing the body part (31) to the wrist.

[0061] And on the lower side of the protrusion (32) of the support member (30), an arc-shaped hanging groove (32a) is provided to allow the fixing ring (10b) of the connecting member (10) to be hung.

[0062] By means of the above-mentioned arc-shaped hanging groove (32a), the fixing ring (10b) can be stably fixed and prevented from coming off during the swinging motion.

[0063] And on both sides of the body part (31), a slot (34) is formed so that one side of the support band (33) is fixed and the other side passes through.

[0064] Here, the slots (34) may be provided in two places on each side of the body part (31), as shown in FIG. 10.

[0065] In this case, the two support bands (33) are each fixed at one side of the slot and pass through the other side of the slot.

[0066] If the above-mentioned support band (33) is composed of two, the support member (30) can be fixed more firmly.

[0067] In addition, on the outer surface of the support band (33), a Velcro tape (commonly called 'hook and loop fastener') is provided to secure the support band after tightening.

[0068] With the above Velcro tape, the support band (33) can be easily secured and unsecured to the wrist.

[0069] Meanwhile, instead of the above Velcro tape, a fixing hook provided on the leather band of the watch may be used.

[0070] Additionally, it is preferable that the support member (30) be fixed to the outer surface of the wristband (40) worn on the user's wrist.

[0071] The above wristband (40) is a known fiber band with a rubber band inside, so a detailed description thereof will be omitted.

[0072] In addition, as shown in FIG. 9, a rubber pad may be attached to the inner surface (35) of the body part (31), or a Velcro tape may be provided.

[0073] The body part (31) can be firmly attached to the outer surface of the wristband (40) by means of a rubber pad or Velcro tape provided on the inner surface (35) of the body part (31).

[0074] The process of wearing the swing assist device according to the present invention is described below.

[0075] First, as shown in FIGS. 4 and 5, the fixing ring (10b) of the connecting member (10) is passed through the through hole (20a) of the fixing band (20) and pulled out.

[0076] Next, the handle ring (10a) and the fixing band (20) are positioned on the appropriate part of the racket handle (103).

[0077] Next, as shown in FIG. 6, a wristband (40) is worn on the user's wrist, and a support member (30) is worn on the outer circumference of the wristband (40).

[0078] At this time, as shown in FIG. 7, the support band (33) is pulled so that the hook groove (32a) of the protrusion (32) faces the user, thereby strongly pressing the support member (30) against the wristband (40).

[0079] Next, the fixing ring (10b) located on the handle part (103) is pulled toward the user and hung on the hook groove (32a) of the protrusion (32).

[0080] Then, by adjusting the position of the handle ring (10a) and the fixing band (20) to the position most suitable for the user, the wearing of the swing assist device is completed.

[0081] According to the present invention, the weight of the tennis racket is distributed toward the wrist, thereby significantly reducing the weight of the racket felt by the user.

[0082] Although this invention cannot be worn by professional tennis players, it can be very useful during tennis lessons for youth or women with weak arm strength, or in amateur matches for the elderly whose arm strength has weakened with age.

[0083] In addition, since it can significantly reduce the weight of the tennis racket during the swing motion, it can be usefully applied even by those with sufficient arm strength when practicing to improve swing speed.

[0084] The foregoing describes preferred embodiments of the present invention by way of example, and the scope of the present invention is not limited to the specific embodiments described above.

[0085] A person skilled in the art to which this invention pertains will understand that various modifications and changes are possible without departing from the scope of the technical concept of this invention. Explanation of the symbols
