Description

[Technical Field]

[0001] The present invention relates to a sensory acquisition aid that allows a user to experience the sensation of transmitting energy gained from swinging their arms through their arms to an implement such as a racket, bat, or ball. [Background technology]

[0002] Various inventions relating to practice rackets have been published in the past (for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 6-17774 Summary of the Invention [Problem to be solved by the invention]

[0004] The above-mentioned tennis and badminton practice rackets have been designed by removing the shaft, frame, and gut of a typical racket, and instead directly connecting the grip and throat, with the hope that they will enable players to improve their muscle strength and technique efficiently in a small space.

[0005] It is true that the practice racket mentioned above can be expected to have a training effect by swinging your arms while holding the tool, but it does not focus on the movements inside the body, making it difficult to connect them to the kinetic chain, so I believe that such an effect cannot be expected.

[0006] In recent years, with the evolution of rackets (lighter weight, etc.), there has been a trend to not practice swinging with a racket due to doubts about the effectiveness of such swings.

[0007] Therefore, the challenge was to gain the sense of transmitting the energy gained from the kinetic chain and body movements (for example, swinging your arms like in a practice swing) to the tool through your arms (grasping). [Means for solving the problem]

[0008] In order to solve the above-mentioned problems, the present invention provides a sensory acquisition aid that has a fluid movement section that contains or is capable of containing a specified fluid in the axial direction of the grip section, and when a person grips the grip section with their hand and swings their hand and arm, the fluid contained in the fluid movement section moves from the grip section side to the opposite grip section side, giving the user the sensation of their arm swinging.

[0009] In order to solve the above-mentioned problems, the present invention provides a sensory acquisition aid that has a fluid movement section that can contain a specified fluid in the axial direction of the grip section, and a specified attachment recess that is placed over the open end of the fluid movement section and secured by screwing is sandwiched between the grip section and the fluid movement section.

[0010] In order to solve the above-mentioned problems, the present invention provides a sensory acquisition aid in which the mounting recess is composed of a lid body having a female thread groove portion on its inner surface, a fixing screw that fixes the lid body and the grip portion, and a washer that is sandwiched between the fixing screw and the lid body.

[0011] In order to solve the above-mentioned problems, the present invention provides a sensory acquisition aid in which the fluid transfer part is a transparent beverage container. [Effects of the Invention]

[0012] The sensory acquisition aid of the present invention is a sensory acquisition aid that has a fluid movement section that contains or is capable of containing a specified fluid in the axial direction of the grip section, and when a person grips the grip section with their hand and swings their hand and arm, the fluid contained in the fluid movement section moves from the grip section side to the non-grip section side, giving the user the sensation of their arm swinging. This makes it easier to grasp the sensation that is transmitted to the tool through the arm via the kinetic chain, and more people can grasp it.

[0013] The sensory acquisition aid of the present invention is a sensory acquisition aid that has a fluid movement section that can contain a specified fluid in the axial direction of the grip section, and a specified attachment recess is sandwiched between the grip section and the fluid movement section that is placed over the opening convex section of the fluid movement section and secured by screwing, making the fluid movement section detachable and improving portability.

[0014] The sensory acquisition aid of the present invention has an attachment recess that is constructed from a lid body having a female thread groove on its inner surface, a fastening screw that fastens the lid body to the grip portion, and a washer that is sandwiched between the fastening screw and the lid body, and therefore is more durable (the fastening durability between the fastening screw and the lid body and the grip portion is excellent).

[0015] In the sensory acquisition aid of the present invention, the fluid transfer section is a transparent beverage container, so the amount of fluid supplied to the fluid transfer section can be easily confirmed visually. Furthermore, compared to the aforementioned tennis and badminton practice rackets, material costs can be reduced, and compared to practice swings using a regular racket, arm swings can be performed in a smaller space. Furthermore, if the fluid supplied to the fluid transfer section is made of luminous beads or the like, the luminescence can be seen (it can be used in dark places and is more aesthetically pleasing).

[0017] When a person holds the grip portion in their hand and swings their hand and arm (such as a practice swing in tennis or badminton), the fluid contained in the fluid moving portion moves from the side of the person's hand to the tip of the fluid moving portion, thereby providing a sensation of the arm being swung, as a sensory acquisition aid. [Example]

[0018] First, the configuration of the sensory acquisition aid will be explained with reference to Figure 1.

[0019] The sensory acquisition aid (1) includes at least a predetermined grip portion (10) and a predetermined fluid transfer portion (20) provided in the axial direction of the grip portion (Fig. 1).

[0020] In this embodiment, the size, shape, and structure of the grip portion (10) is similar to the grip of a baseball bat, but any size, shape, and structure is acceptable as long as it can be held by a human hand (child, student, or adult). In this embodiment, the grip portion and the fluid transfer portion (20) are connected, but they may also be separated (Fig. 1).

[0021] The fluid transfer portion (20) may be any portion that can store the fluid therein without leaking.

[0022] In this embodiment, a certain amount of beads are stored inside the fluid transfer section (20) as the fluid (40) contained in the fluid transfer section (20) (FIG. 1).

[0023] In this embodiment, beads are selected as the fluid (40), but it is possible to use anything other than beads as long as it can flow inside the fluid transfer section, and it is believed that it can also be replaced by liquids such as water, powders such as sand or flour, or viscous gel-like materials. [Example]

[0024] The sensation acquisition aid of Example 2 has a detachable fluid-moving part, and its configuration will be described with reference to FIGS. 2 to 4. FIG.

[0025] The sensory acquisition aid (1) comprises a grip portion (10) that the user holds in their hand when swinging their arm, a fluid transfer portion (20) that can contain a specified fluid in the axial direction of the grip portion, and a specified attachment recess (30) that is sandwiched between the grip portion and the fluid transfer portion, placed over the open end of the fluid transfer portion, and secured by screwing (Figure 2).

[0026] Regarding the size, shape, and structure of the grip portion (10), in this embodiment it is cylindrical with a diameter of 25 mm, but any size, shape, and structure is acceptable as long as it is large enough to be held by a human hand (child, student, or adult). For example, it may be hollow and cylindrical to accommodate those who desire a lighter weight. It is preferable to use a size, shape, and structure that is less likely to slip when swinging the arm.

[0027] Regarding the material of the grip portion (10), in this embodiment, wood is used, which is easy to manufacture and process and can be manufactured in small or large lots, but it is also acceptable to select various materials taking into consideration the number of units to be manufactured, manufacturing and processing costs, or user preferences.

[0028] The fluid transfer portion (20) may be any portion that can store the fluid therein without leaking.

[0029] Regarding the shape and structure of the fluid transfer portion (20), it is necessary to provide a predetermined male screw groove portion (211) on the outer circumferential surface of the opening convex portion (the uppermost portion shown in FIG. 3) (FIG. 3).

[0030] In addition, it is preferable to provide an event display section (212) on the surface or inside of the fluid movement section (20) that displays the sport and its movements that the user wants to acquire sensations from by holding the sensory acquisition aid of the present application and swinging their arms (Figure 3).

[0031] As a specific example of the display of the event, etc. display section (212), it is assumed that "A" shown in FIG. 3 will display "Junior Tennis Swing" and "B" will display "Junior Badminton Smash" (FIG. 3).

[0032] Regarding the method of providing the event display section (212), methods such as attaching, printing or engraving a sheet-like material on the surface of the fluid transfer section (20) or providing a rod-like body with a scale inside the fluid transfer section are envisaged.

[0033] In this embodiment, a transparent 500 ml beverage container (21) made of resin after the beverage has been consumed is used as the fluid transfer part (20) (FIGS. 2 and 3).

[0034] Regarding the size, dimensions, and capacity of the beverage container (21) as the fluid transfer part, a beverage container with a size, dimensions, and capacity of approximately 220 milliliters to 2 liters is assumed, but considering space-saving use, it is preferable to select a container as small as possible.

[0035] Regarding the material of the beverage container (21) as the fluid transfer part, any material currently used for beverage containers is acceptable, but considering that the sensory acquisition aid of the present application will be held in a small space and used to swing the arm, it is preferable to select a soft material such as resin that is safe even if it accidentally comes into contact with a person.

[0036] Regarding the appearance of the beverage container (21) as the fluid transfer part, any appearance that is actually used as a beverage container is acceptable, but considering the work of supplying the fluid into the beverage container, it is preferable for the beverage container to be fully transparent, partially transparent, or translucent, so that the amount of fluid being supplied can be easily visually confirmed.

[0037] Although the beverage container (21) has been described as the fluid transfer portion, it is also acceptable to use a condiment container, a hair wash container, or the like instead of a beverage container.

[0038] The mounting recess (30) is composed of a lid (31) having a predetermined female thread groove (311) on its inner surface, a fixing screw (32) that fixes the lid and the grip portion (10), and a washer (33) that is sandwiched between the fixing screw and the lid (Figure 4).

[0039] In this embodiment, the cover (31) is made of resin.

[0040] The female thread groove portion (311) provided on the inner surface of the cover body (31) and the male thread groove portion (211) provided on the outer surface of the opening convex portion of the fluid movement portion (20) must correspond so that they can be fixed by screwing together (Figures 2 to 4).

[0041] Regarding the fastening screw 32, any screw (e.g., tapping screw) is acceptable as long as it can fasten the cover 31 to the grip portion 10. In this embodiment, since the grip portion is made of wood, a wood screw with excellent durability is used.

[0042] Next, an image of how the sensation acquisition aid of the second embodiment is used will be described with reference to FIGS.

[0043] After supplying water (40) up to the "A" position of the event display section (212) on the surface of the fluid transfer section (20), the mounting recess (30) is placed over the opening convex section of the fluid transfer section and rotated clockwise to secure (mount) the fluid transfer section by screwing it in place (Figure 5).

[0044] Thereafter, the grip portion (10) is grasped by a person's hand and a tennis arm swing motion (swing motion, practice swing motion) is performed (FIG. 6).

[0045] The above-mentioned arm swinging action causes the water (40) contained in the fluid-moving portion to move from the grip portion side (closer to the person's hand) inside the fluid-moving portion to the anti-grip portion side (away from the person) (in the direction of the arrow shown in Figure 6), giving the sensation of the arm swinging (Figure 6).

[0046] Regarding the amount of water to be supplied to the inside of the fluid transfer section, although there are individual differences, based on experience, we believe that approximately 300 milliliters (equivalent to the weight of a child's tennis racket) is preferable when performing the arm swinging motion in junior tennis.

[0047] In this embodiment, water is selected as the fluid (40), but any material other than water may be used as long as it is capable of flowing inside the fluid transfer section, and it is believed that such materials as powders such as sand or flour, solids such as beads or marbles, or viscous gel-like materials may also be used.

[0048] In addition, if a solid such as beads or marbles is selected as the fluid (40), it is possible that the sound produced when it flows may have some effect. [Example]

[0049] The sensory acquisition aid of Example 3 is designed to simulate the arm swinging motion of badminton, which is lighter than a tennis racket. Since the configuration is substantially the same as Example 2, only the image of how to use the sensory acquisition aid will be described with reference to Figures 7 and 8.

[0050] After supplying water (40) up to the "B" position of the event display section (212) attached to the surface of the fluid transfer section (20), the mounting recess (30) is placed over the opening convex section of the fluid transfer section and rotated clockwise to secure (mount) the fluid transfer section by screwing it in place (Figure 7).

[0051] Thereafter, the grip portion (10) is grasped by the hand and a badminton arm swing motion (smash motion, practice swing motion) is performed (FIG. 8).

[0052] The above-mentioned arm swinging action causes the water (40) contained in the fluid-moving portion to move from the grip portion side (closer to the person's hand) inside the fluid-moving portion to the anti-grip portion side (away from the person) (in the direction of the arrow shown in Figure 8), giving the sensation of the arm swinging (Figure 8).

[0053] Regarding the amount of water to be supplied to the inside of the fluid transfer part (20), although there are individual differences, based on experience, we believe that approximately 90 milliliters (similar to the weight of a child's badminton racket) is preferable when performing the arm swinging motion in junior badminton.

[0054] Furthermore, assuming that the amount of water supplied to the inside of the fluid transfer section (20) will be less than in Example 2, it is believed that making the fluid transfer section even smaller (for example, a 220 ml beverage container) would also be effective in terms of space-saving use.

[0055] In Example 2, the sensory acquisition aid was explained using tennis as an example, and in Example 3, badminton as an example, but it is not limited to these, and it is believed that similar effects may be obtained in other sports such as golf, baseball, and softball.

[0056] In the case of baseball, it is believed that it can be used not only to obtain the batting motion (movement of swinging the arm horizontally) but also the pitching motion (movement of swinging the arm from top to bottom).

[0057] It is expected that by selecting the appropriate amount and type of fluid, a certain degree of effect can be obtained in any of the sports and movements mentioned above.

[0058] It is expected that there will be individual differences in the effects that can be obtained (grasped) by using the sensory acquisition aid of the present application, but by grasping the aforementioned "sense of the arm being swung, and the sense of that being transmitted to the tool through the arm via that kinetic chain," it is believed that specific effects such as correction of grip, impact, spatial awareness, swing, correction of serve pronation movement, pronation movement, wrist work, and pitching movement will appear. [Industrial Applicability]

[0059] The present invention has industrial applicability because it is an excellent sensory acquisition aid that allows users to obtain the sensation of a specific arm swing, making it easier for them to grasp the sensation transmitted to the tool through the arm via the kinetic chain, and allowing more people to grasp it.
