Abstract
Description
Technical Field
[0001] This utility model relates to the field of sports equipment technology, and in particular to a badminton grip training device. Background Technology
[0002] The handles of existing badminton rackets are generally octagonal cylinders. Beginners often struggle to master the correct grip, which can negatively impact shot quality and shuttlecock placement. Many badminton enthusiasts develop ingrained habits from using incorrect grip techniques, which are difficult to correct with technical guidance. Therefore, some badminton enthusiasts need to use badminton grip trainers to standardize (shape and correct) their racket grip posture. Currently, there are two types of badminton grip trainers on the market. One type has a thumb groove for the thumb and an index finger groove for the index finger, which provides guidance on the grip position of the thumb and index finger. However, due to the lack of function to restrict finger movement, the thumb and index finger may easily leave the thumb and index finger grooves during badminton play, failing to provide a continuous posture standardization effect. The other type has blocks on both sides of the thumb and index finger grooves to restrict finger movement, which can provide a continuous posture standardization effect. However, the blocks are made of harder material, and if the user grips the handle tightly and swings the racket, the hand is pressed tightly against the trainer, which can produce a strong uncomfortable feeling. Utility Model Content
[0003] In view of this, in order to solve the problems that existing badminton grip trainers cannot provide continuous posture correction and are not conducive to gripping the racket and generating power, the present invention provides a badminton grip trainer.

[0031] Example 1
[0032] Please refer to Figure 1 and Figure 2 The present invention provides a badminton grip training device, which mainly includes a sleeve 1, a thumb groove 2, an index finger groove 3, and a first interlocking plate 9.
[0033] The sleeve 1 is generally made of plastic, and its cross-section is octagonal, the same as the cross-sectional shape of a standard badminton racket handle. The sleeve 1 has eight sides, which allows it to be stably fitted onto the badminton racket handle.
[0034] To facilitate the insertion of the sleeve 1, a notch 10 extending through the sleeve 1 along the front-to-back direction is provided on one side of the sleeve 1. In this embodiment, the sleeve 1 has a notch 10 extending through the sleeve 1 along the front-to-back direction on its narrowest side. The notch 10 allows the sleeve 1 to undergo a certain degree of adaptability deformation, thus enabling it to be more stably and accurately fitted onto the badminton racket handle.
[0035] The thumb groove 2 is located on the upper side of the rear end of the sleeve 1. The thumb groove 2 is axially inclined relative to the sleeve 1 and has thumb blocks on both sides, which are arranged along the front-back direction. The thumb groove 2 is an open groove that is approximately parallelogram-shaped. The two thumb blocks are arc-shaped blocks, respectively located on the rear of opposite sides of the thumb groove 2. When the front of the thumb is pressed into the thumb groove 2, the two sides of the thumb are blocked by the two thumb blocks, thus limiting the thumb's position.
[0036] The index finger groove 3 is located on the lower side of the rear end of the sleeve 1, and in front of the thumb groove 2. The index finger groove 3 is similarly inclined relative to the axial direction of the sleeve 1, and is an open groove with an approximately parallelogram shape. An index finger inner side stop 6 is provided on one side of the index finger groove 3, and the index finger inner side stop 6 is an arc-shaped block.
[0037] Combination Figure 3 and Figure 4 As shown, the inner wall of the sleeve 1 located on the side where the index finger groove 3 is located is provided with a first groove 8, which is a recessed groove relative to the inner wall of the sleeve 1.
[0038] The first fitting plate 9 is embedded in the first groove 8, and the rear end of the first fitting plate 9 is provided with an outwardly protruding index finger outer stop 7. The shape of the first fitting plate 9 is adapted to the first groove 8, so that the first fitting plate 9 can be stably embedded in the first groove 8. The index finger outer stop 7 is an arc-shaped block provided along the rear edge of the first fitting plate 9, and the inner edge of the index finger outer stop 7 coincides with one side of the index finger groove 3. Thus, the index finger outer stop 7 protrudes outward along the surface of the sleeve 1, so that the index finger inner stop 6 and the index finger outer stop 7 are respectively located on both sides of the index finger groove 3.
[0039] Generally, the length of the outer index finger stop 7 is greater than the length of the inner index finger stop 6, so that the outer index finger stop 7 has a larger contact area.
[0040] The first fitting plate 9 and the first recess 8 are detachably connected by a first latch. The number of first latches can be multiple. Specifically, the first latch includes a first male latch and a first female latch, one of which is disposed within the first recess 8, and the other is disposed on the first fitting plate 9. In this embodiment, the first male latch is fitted into the first recess 8, and the first female latch is fitted onto the outer surface of the first fitting plate 9. This facilitates the addition and replacement of the first fitting.
[0041] The first interlocking plate 9 and the first groove 8 can also be directly bonded together with glue, that is, glue is applied between the contact surfaces of the first interlocking plate 9 and the first groove 8 to achieve bonding and fixation.
[0042] In order to ensure that the thumb is pressed against the thumb groove 2 while the index finger is accurately pressed into the index finger groove 3, the thumb groove 2 and the index finger groove 3 are respectively set on two opposite continuous three sides of the sleeve 1.
[0043] To ensure that the inner wall of the sleeve 1 is flush, the depth of the first groove 8 is the same as the thickness of the first fitting plate 9. After the first fitting plate 9 is inserted into the first fitting groove, the inner wall of the sleeve 1 is flush, thus avoiding interference with the sleeve 1 being fitted onto the racket handle.
[0044] The outer edge stop 7 of the index finger and the first interlocking plate 9 are generally made of elastic materials, such as rubber or silicone. When the index finger is accurately pressed into the index finger groove 3, the outer edge stop 7 of the index finger contacts the outer side of the index finger, providing a large contact area.
[0045] Example 2
[0046] like Figure 5 and Figure 6 As shown, Embodiment 2 of the present invention provides a badminton grip training device, wherein a thumb stop for contacting the outer side of the thumb is also detachably mounted on the sleeve 1 in the manner described in Embodiment 1, using the same method as the index finger outer side stop 7. Specifically:
[0047] The two thumb blocks are the inner thumb block 4 and the outer thumb block 5, wherein the inner thumb block 4 is integrally formed with the sleeve 1, and the front end of the outer thumb block 5 is provided with a second fitting plate 11. The inner wall of the side of the sleeve 1 adjacent to the thumb groove 2 is provided with a second groove, and the second fitting plate 11 is embedded in the second groove, so that the outer thumb block 5 protrudes outward relative to the sleeve 1.
[0048] The shape of the second fitting plate 11 is adapted to the second groove, so that the second fitting plate 11 can be stably embedded in the second groove. The thumb outer stop 5 is an arc-shaped block that is offset from the second fitting plate 11 towards the thumb groove 2. The inner edge of the thumb outer stop 5 coincides with the rear part of one side of the thumb groove 2. Thus, the thumb outer stop 5 protrudes outward along the surface of the sleeve 1, so that the thumb inner stop 4 and the thumb outer stop 5 are located on both sides of the thumb groove 2.
[0049] Similarly, the second fitting plate 11 is connected to the second recess via a second fastener. Specifically, the second fastener includes a second male fastener and a second female fastener, one of which is disposed within the second recess and the other is disposed on the second fitting plate 11.
[0050] The thumb outer stop 5 and the second fitting plate 11 are generally made of elastic materials, such as rubber or silicone. When the thumb is accurately pressed into the thumb groove 2, the thumb outer stop 5 contacts the outer side of the thumb, providing a large contact area.
[0051] In use, the badminton grip training device of this utility model involves fitting the sleeve 1 onto the racket handle, with the thumb groove 2 and index finger groove 3 facing backward, and the thumb groove 2 facing upward and the index finger groove 3 facing downward. The user places their thumb in the thumb groove 2 and presses it against the racket handle, with the two thumb stops blocking the sides of the thumb. Simultaneously, the index finger is placed in the index finger groove 3 and also pressed against the racket handle, with the inner index finger stop 6 automatically blocking the inner side of the index finger. Furthermore, the elastic outer index finger stop 7 and the elastic thumb stop 5, both made of elastic material, provide a larger contact area between the outer thumb stop 7 and the inner thumb. This tighter contact between the index finger and thumb with the outer thumb stop 7 and thumb stop 5, respectively, facilitates the exertion of force by the index finger and thumb, reduces friction between the index finger and thumb, and improves comfort.
