Description

[Technical field]

[0001] The present invention relates to an everyday graspable object that can increase the range of motion of a joint. [Background technology]

[0002] As we age, our joints lose flexibility and our bodies become stiff, but losing flexibility can lead to unexpected injuries. In particular, elderly people who break their legs when they fall or fall are more likely to become bedridden, and it has been reported that becoming bedridden can lead to the progression of dementia. Even if you are not elderly, poor flexibility can lead to unexpected serious accidents. In addition, there is a risk of unexpected injuries such as rupturing the Achilles tendon or injuring muscles during sports. High flexibility can prevent such unexpected accidents, injuries, and disabilities. This flexibility is one of the physical strengths of humans, and refers to the ability of muscles and tendons to stretch. It is considered to be one of the athletic abilities along with muscle strength, explosive power, endurance, and coordination, and is a physical ability that is the basis of basic actions. In other words, high flexibility means that the range of motion of the joints is expanded, realizing supple movement. In order to maintain and promote health and be active with peace of mind in the era of 100-year lifespans, it is one of the very important efforts to improve and maintain flexibility, which is the ability to smoothly perform actions, a component of physical strength, as a physical ability that is the basis of basic actions.

[0003] For example, Patent Document 1 proposes a stretching aid for improving flexibility, which comprises a footboard, a heel stopper protruding from the upper side of the rear end of the footboard, and a support member which supports the footboard at a desired angle, the top surface of the footboard has a desired number of engaging grooves for angle adjustment formed in parallel in the front-to-back direction of the board at a specified interval toward the width of the board, and the support member comprises a pair of leg rods of specified length arranged parallel to each other at a distance slightly longer than the width of the board, a connecting rod which connects both leg rods fixedly together, engaging rods at the upper ends of both leg rods, positioned on a line connecting both leg rods and formed at a right angle to engage with the grooves, and a support rod located below the engaging rod and fixedly bridged horizontally between both leg rods with a distance corresponding to the thickness of the board between the engaging rod and the engaging rod.

[0004] According to the stretching aid, when the footboard is inserted between the engaging rod and the support rod of the support member from the tip side, engaging the engaging rod with the engaging groove, and in this state the leg rod is opened toward the front side of the footboard and the footboard is placed on the ground, the footboard is supported by the support rod and fixed by the wedge action with the engaging rod, and is stably supported in an inclined state. Therefore, by standing on the footboard and using it in the same way as before, it is said to have various excellent stretching effects, such as strengthening the Achilles tendon.

[0005] [Patent Document 1] Japanese Patent Application Publication No. 11-299926 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the conventional methods for increasing the range of motion of joints have problems such as using large-scale equipment and causing pain and discomfort to the muscles when stretching them, making them difficult to perform easily and continuously. In addition, if stretching is not performed for a while, flexibility returns to its original state. Thus, the conventional methods for increasing the range of motion of joints have been ineffective or have no prospect of being effective. For this reason, a more effective method is desired.

[0007] The present invention has been made in consideration of the above-mentioned problems, and aims to provide an everyday gripping object that can promote muscle elongation and increase the range of motion of joints by pressing on the Pacinian corpuscles. [Means for solving the problem]

[0008] In order to solve the above problems, the inventors discovered that pressing specific Pacinian corpuscles (specifically, those present in the palm of the hand), among the numerous Pacinian corpuscles present in the human body, promotes muscle elongation, and that this reduction can increase the range of motion of the joints, and thus completed the present invention. Effect of the Invention

[0009] According to the present invention, it is possible to provide a daily gripping object that can promote muscle elongation and increase the range of motion of joints. Moreover, according to the present invention, when the daily gripping object is used, the muscle elongation effect continues for a certain period of time (for example, 5 minutes) after use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described with reference to the accompanying drawings, in which: The positions of the Pacinian corpuscles in the palm of the human body are generally in the same position, but the positions vary slightly from person to person and from left to right hand to hand. The device according to the embodiment is a hand tool to be held in one hand and has a structure in which, when held in the palm of the hand, the Pacinian ball (the contact part 21 of the pressing part 20), which is a protrusion provided on the main body, hits the exact position of the Pacinian corpuscles every time. The device according to the embodiment is also characterized in that the force or pressure can be adjusted so that an appropriate pressure can be applied to maximize the effect of the Pacinian corpuscles (muscle relaxant effect).

[0012] (Pacinian corpuscles) Pacinian corpuscles are sensory receptors that detect pressure and vibration, and in the hand, as shown in Fig. 30, they are present near the center (A in the figure) of the palm on the little finger side (the surface from the wrist to the base of the fingers that is on the inside when the hand is clenched) and at the tip of the middle finger (B in the figure). Of these, the Pacinian corpuscles according to the present invention are those present in the palm (A in the figure). The device 1 according to the embodiment stimulates the Pacinian corpuscles present near the center of the palm on the little finger side. The present invention aims to reduce pain on the side of a muscle being stretched by applying pressure stimulation to the Pacinian corpuscles.

[0013] [First embodiment] (Configuration of Instrument 1) The configuration of the device 1 will be described with reference to Fig. 1 to Fig. 4. The device 1 according to the embodiment is a device for increasing the range of motion of a joint. Specifically, the device aims to promote muscle stretching while reducing pain on the side where the muscle is stretched during muscle stretching, and to increase the range of motion of the joint during exercise, thereby enabling the user to perform exercise more smoothly.

[0014] Fig. 1(a) is a plan view of the device 1, Fig. 1(b) is a right side view of the device 1, Fig. 1(c) is a bottom view of the device 1, Fig. 1(d) is a rear view of the device 1, and Fig. 1(e) is a front view of the device 1. Fig. 2 is an enlarged view of Fig. 1(b). Fig. 3(a) is a plan view of the device 1, and Fig. 3(b) is a left side view of the device 1. Figs. 4 and 5 are diagrams for explaining the functions of each part of the device 1.

[0015] In the following explanation, as shown in FIG. 3, the horizontal direction relative to an imaginary line connecting the two second stoppers 11B perpendicular to the Y axis is defined as the X axis, the longitudinal direction of the device 1 is defined as the Y axis, and the horizontal direction relative to an imaginary line connecting the first recess 12A and the abutment portion 21 perpendicular to the Y axis is defined as the Z axis.

[0016] The instrument 1 is designed so that when the instrument 1 is grasped by a grasping method described below, the contact portion 21 of the instrument 1 comes to a position that comes into contact with the location of the Pacinian corpuscles. The instrument 1 is designed to stimulate the Pacinian corpuscles by pressing the contact surface 21A of the contact portion 21 of the instrument 1 with the gripping force of the little finger and the auxiliary gripping force of the ring finger. The contact portion 21 is spherical so that only the Pacinian corpuscles can be pressed with pinpoint accuracy (it is preferable that the contact portion 21 has a shape that does not stimulate (cannot be touched or is difficult to touch) anything other than the Pacinian corpuscles).

[0017] The device 1 includes a main body 10 to be held by a user, and a pressing part 20 that protrudes from the main body 10 and stimulates the Pacinian corpuscles present in the palm of the user's hand by pressing the Pacinian corpuscles when the main body 10 is held by the user. The pressing part 20 includes an abutment part 21 (Pacinian ball) having an abutment surface 21A that abuts the Pacinian corpuscles, and a connection part 22 that connects the main body 10 and the abutment part 21 by separating from the palm of the user's hand when the main body 10 is held by the user. Here, the abutment part 21 has a shape that can pinpoint press only the Pacinian corpuscles (although the abutment part 21 is ball-shaped in this embodiment, it is sufficient to pinpoint press only the Pacinian corpuscles, and does not prevent it from having another shape) (it is preferable that the abutment part 21 has a shape that does not stimulate anything other than the Pacinian corpuscles (it does not touch or is difficult to touch).

[0018] The main body 10 of the device 1 is provided with a first stopper 11A that protrudes from the main body 10 and abuts against the little finger of the user when the main body 10 is held by the user, thereby positioning the device 1 within the palm of the user's hand. The first stopper 11A restricts upward movement along the Y axis.

[0019] The main body 10 of the device 1 also includes a second stopper 11B that protrudes from the main body 10 and is positioned between the index finger and middle finger of the user when the main body 10 is held by the user, restricting rotation of the device 1 within the palm of the user. The first stopper 11A restricts downward movement along the Y axis.

[0020] Furthermore, the main body 10 of the device 1 includes a third stopper 11C that protrudes from the main body 10 and abuts against the base of the user's thumb when the main body 10 is held by the user, thereby restricting the rotation of the device 1 in the palm of the user's hand. As shown in Fig. 3, the first stopper 11A restricts the downward movement of the device 1 along the Y axis.

[0021] As described above, the first to third stoppers 11A to 11C restrict the movement of the instrument 1 downward along the Y axis, and the position of the instrument 1 in the palm of the hand does not move in the Y axis direction when gripped. Furthermore, if the instrument 1 rotates in the palm, the contact portion 21 will be displaced from the position of the Pacinian corpuscles. In order to press the Pacinian corpuscles with the contact portion 21 by the force of the little finger, the instrument 1 must not rotate in the palm. Therefore, as shown in FIG. 4, the second stopper 11B restricts clockwise rotation, and the third stopper 11C restricts counterclockwise rotation, restricting the rotation of the instrument 1 gripped in the palm, and the pressing force of the little finger is reliably transmitted to the Pacinian corpuscles via the instrument 1. In this way, the instrument 1 is designed so that the instrument 1 comes to the intended position on the palm of the hand (the position where the contact portion 21 (Pacinian ball) of the pressing portion 20 contacts the Pacinian corpuscles) at three points: the first stopper 11A as the starting point, the second stopper 11B, and the third stopper 11C.

[0022] The main body of the instrument 1 has a first recess 12A for positioning the user's little finger at a position substantially opposite to the position where the pressing unit 20 is provided. The main body of the instrument 1 has a second recess 12B for positioning the user's ring finger adjacent to the first recess 12A. The instrument 1 of the embodiment is configured such that the pressing unit 20 presses the Pacinian corpuscles with an appropriate force as shown in FIG. 5 by gripping the main body 10 with the user's little finger positioned in the first recess 12A of the main body 10 and the user's ring finger positioned in the second recess 12B.

[0023] In the embodiment of the device 1, the pressing part 20 is spherical. When the Pacinian corpuscles are pressed and stimulated, if other sensory receptors around the Pacinian corpuscles are stimulated, they become disturbances and the sensitivity of the pressure stimulus to the Pacinian corpuscles is weakened. By making the contact part 21 (Pacinian ball) of the pressing part 20 spherical, the pressure stimulus can be concentrated only on the Pacinian corpuscles, so a predetermined range of space is formed around the contact part 21 of the ball-shaped pressing part 20 that applies pressure, and the effect of the present invention is enhanced. In addition, since the contact portion 21 (Pacinian ball) of the pressing portion 20 of the device 1 sinks into the palm by about 1 mm to 15 mm (preferably 3 to 10 mm), it is preferable that a space is formed around the contact portion 21 (Pacinian ball) of the pressing portion 20 of the device 1 so as not to stimulate sensory receptors other than the Pacinian corpuscles when the contact portion 21 (Pacinian ball) of the pressing portion 20 of the device 1 sinks into the palm by about 1 mm to 15 mm as shown in Fig. 5. In addition, the contact portion 21 of the pressing portion 20 does not necessarily have to be spherical as long as a space of a predetermined range is formed around the contact portion 21 of the pressing portion 20 and the pressure stimulus can be concentrated only on the Pacinian corpuscles.

[0024] As described above, it is preferable to pinpoint-press the Pacinian corpuscles of the palm. This point will be explained in more detail. The palm has the ulnar nerve. It is understood that in addition to the Pacinian corpuscles, other mechanoreceptors also exist on the ulnar nerve. Under these circumstances, it is preferable that the instrument according to the present invention is designed so that the pressure applied to the Pacinian corpuscles of the palm is greater than the pressure applied to the other mechanoreceptors of the palm when the instrument according to the present invention is used. From another point of view, it is preferable that a space is formed around the contact portion when the instrument according to the present invention is used. In other words, it is preferable that a region (non-contact region) where the instrument does not contact the palm is formed outside the region (contact region) where the contact portion contacts the palm so as to surround the contact region.

[0025] As described above, it is preferable that the pressing part 20 pinpoint presses the Pacinian corpuscles in the palm. The pressing part 20 can be directed to the Pacinian corpuscles in the palm during use, and the contact part 21 preferably has a curved surface that bulges toward the Pacinian corpuscles. The curved surface may be spherical or aspherical. The degree of bulging may be determined appropriately. For example, when the Pacinian corpuscles are to be strongly stimulated, the degree of bulging may be increased, and when the Pacinian corpuscles are to be weakly stimulated, the degree of bulging may be decreased (closer to a flat surface). Furthermore, the pressing part 20 may be formed of a cylinder. When the pressing part 20 is formed of a cylinder, the bottom surface of the cylinder becomes the contact part 21, and the contact part 21 has a flat shape. The flat surface faces and contacts the Pacinian corpuscles. Furthermore, the pressing part 20 may be formed of multiple cylinders arranged concentrically with different radii. Regardless of the shape of the pressing portion 20, it is sufficient that it can be directed toward the Pacinian corpuscles in the palm of the hand during use and can concentrate pressure on the Pacinian corpuscles.

[0026] (Method of holding instrument 1) A method of using (holding) the device 1 will be described with reference to Figs. (1) The contact surface 21A of the contact portion 21 (Pacinian ball) of the instrument 1 is aligned with the position of the Pacinian corpuscles (see FIG. 6(a)). (2) Grip main body 10 of main body 1 by placing the little finger against second stopper 11A, the little finger in first recess 12A, and the ring finger in second recess 12B (see FIG. 6(b)). Since fingers and hands adapt to the shape of the object being grasped, even if the contact portion 21 (Pacinian ball) is aligned with the position of the Pacinian corpuscles, the object can be grasped at the position of the little finger stopper. (3) The middle finger is brought into contact with the second stopper 11B to grip the main body 10 of the main body 1 (see FIG. 7(a)). (4) The user places the base of the thumb (webbed area) against third stopper 11C and grasps main body 10 of main body 1 (see FIG. 7(b)). (5) The position of the instrument 1 in the palm is properly determined by the first to third stoppers 11A to 11C. In other words, the contact surface 21A of the contact portion 21 of the instrument 1 matches the position of the Pacinian corpuscles (see FIG. 7(c)).

[0027] As shown in FIG. 3(a), the device 1 is configured to be symmetrical about the Y axis in a plan view, but it is not necessarily required to be configured to be symmetrical about the Y axis in a plan view.

[0028] As described above, the device 1 according to the embodiment is a device for increasing the range of motion of a joint. The device 1 includes a main body 10 that is held by a user, and a pressure unit 20 that protrudes from the main body 10 and stimulates the Pacinian corpuscles present in the palm of the user's hand by applying pressure when the main body 10 is held by the user. This allows stretching to be performed while stimulating the Pacinian corpuscles, and the range of motion of a joint can be increased more effectively.

[0029] The pressing unit 20 of the device 1 according to this embodiment includes a contact unit 21 having a contact surface that contacts the Pacinian corpuscles, and a connection unit 22 that connects the main body unit 10 and the contact unit by moving away from the palm of the user's hand when the main body unit 10 is held by the user. This makes it possible to press and stimulate only the Pacinian corpuscles, more effectively inducing muscle relaxation and expanding the range of motion of the joints.

[0030] The main body 10 of the device 1 according to this embodiment has a first recess 12A for positioning the user's little finger at a position substantially opposite to the position where the pressing unit 20 is provided, and is configured so that the Pacinian corpuscles are pressed by the pressing unit 20 when the user grasps the main body 10 with the user's little finger positioned in the first recess 12A of the main body 10. In this way, the device 1 can be positioned within the palm of the user's hand, so that the Pacinian corpuscles can be reliably pressed and stimulated.

[0031] The main body 10 of the device 1 according to this embodiment has a second recess 12B adjacent to the first recess 12A for positioning the user's ring finger, and is configured so that the Pacinian corpuscles are pressed by the pressing part 20 by gripping the main body 10 with the user's ring finger positioned in the second recess 12B of the main body 10. In this way, the device 1 can be positioned within the palm of the user's hand, so that the Pacinian corpuscles can be reliably pressed and stimulated.

[0032] The main body 10 of the device 1 according to this embodiment is provided with a first stopper 11A that protrudes from the main body 10 and abuts against the little finger of the user when the main body 10 is held by the user, thereby positioning the device within the user's palm. In this way, the device 1 can be positioned within the user's palm, so that the Pacinian corpuscles can be reliably pressed and stimulated.

[0033] The main body 10 of the device 1 according to this embodiment is provided with a second stopper 11B that protrudes from the main body 10 and is positioned between the index finger and middle finger of the user when the main body 10 is held by the user, and that restricts the rotation of the device 1 within the user's palm. In this way, the device 1 can be positioned within the user's palm, so that the Pacinian corpuscles can be reliably pressed and stimulated.

[0034] The main body 10 of the device 1 according to this embodiment is provided with a third stopper 11C that protrudes from the main body 10 and abuts against the base of the user's thumb when the main body 10 is held by the user, thereby restricting the rotation of the device within the user's palm. In this way, the device 1 can be positioned within the user's palm, so that the Pacinian corpuscles can be reliably pressed and stimulated.

[0035] [Modifications of the embodiment] Fig. 8 is a diagram for explaining the configuration of the device 1 according to the modified embodiment. Fig. 8(a) is a diagram showing the device 1 according to the modified embodiment separated, and Fig. 8(b) is a diagram showing the device 1 according to the modified embodiment assembled. In the above embodiment, the positions of the pressing part 20 and the first to third stoppers 11A to 11C of the device 1 were fixed to the main body part 10, but the device 1 according to the modified embodiment is configured so that the pressing part 20 and the first to third stoppers 11A to 11C are separable from the main body part 10.

[0036] As shown in Fig. 8(a), in the device 1 according to the modified embodiment, the main body 10 is configured to be separable into a first main body 101, a second main body 102, a third main body 103, and a fourth main body 104. The first main body 101 is provided with a recess 101b whose longitudinal direction is parallel to the Y-axis, and the pressing part 20 is provided with a protrusion 20a which slidably engages with the recess 101b. The protrusion 20a of the pressing part 20 slidably engages with the recess 101b of the first main body 101, so that the position of the contact part 21 (Pacinian ball) of the pressing part 20 can be adjusted parallel to the Y-axis.

[0037] Moreover, the first body portion 101 is provided with a protruding portion 101a whose longitudinal direction is parallel to the Y-axis, and the second body portion 102 is provided with a recessed portion 102c which slidably engages with the protruding portion 101a of the first body portion 101. The protruding portion 101a of the first body portion 101 slidably engages with the recessed portion 102c of the second body portion 102, so that the position of the first stopper 11A (little finger stopper) can be adjusted parallel to the Y-axis (note that by adjusting the position of the first stopper 11A (little finger stopper), the position of the abutment portion 21 (Pacinian ball) can also be adjusted).

[0038] Second body portion 102 is provided with protrusion 102a whose longitudinal direction is parallel to the Y-axis, and third body portion 103 is provided with recess 103b which slidably engages with protrusion 102a of second body portion 102. Then, recess 103b of third body portion 103 slidably engages with protrusion 102a of second body portion 102, so that the position of third stopper 11C (thumb stopper) can be adjusted parallel to the Y-axis.

[0039] Further, second body portion 102 is provided with convex portion 102b whose longitudinal direction is parallel to the Y-axis, and fourth body portion 104 is provided with concave portion 104b which slidably engages with convex portion 102b of second body portion 102. Then, by slidably engaging concave portion 104b of fourth body portion 104 with convex portion 102b of second body portion 102, the position of second stopper 11B (middle finger stopper) can be adjusted parallel to the Y-axis.

[0040] By configuring it in this manner, the positions of the contact portion 21 (Pacinian ball) of the pressing portion 20 and the first to third stoppers 11A to 11C can be adjusted to suit the differences in size and shape of each user's hand, and by holding the device in one hand, the contact portion 21 (Pacinian ball) of the pressing portion 20 can accurately contact the Pacinian corpuscles, applying an appropriate amount of pressure.

[0041] The function and configuration of the tool 1 according to the modified embodiment shown in Fig. 8 are the same as those of the tool 1 according to the embodiment described with reference to Figs. 1 to 7, except that the positions of the contact portion 21 (Pacinian ball) of the pressing portion 20 and the first to third stoppers 11A to 11C can be adjusted to suit the size and shape of each user's hand. Therefore, a redundant description of the function and gripping method of the tool 1 according to the modified embodiment shown in Fig. 8 will be omitted (for the function and gripping method, see Figs. 4 to 7 and the corresponding descriptions).

[0042] As described later in the examples, the effect of the present invention can be achieved if the Pacinian corpuscles can be stimulated by pressing or the like. For this reason, the shape of the device does not necessarily have to be gripped with one hand like the device 1 according to the embodiment described with reference to Figs. 1 to 6, and may be, for example, a clip-shaped device provided with a pressing part that contacts the Pacinian corpuscles by pressing the Pacinian corpuscles so as to pinch the palm of the hand. Also, a pressing part having a contact surface that contacts the Pacinian corpuscles may be provided on the inside of the glove. Furthermore, the shape of the device may be, for example, a shape that can be held with both hands (including a rod-like or handle-like shape, a game controller shape, etc.). In this case, it is possible to provide two pressing parts 20 in one device, corresponding to the left and right hands.

[0043] [Application] The device according to the present invention is effective for various applications involving muscle elongation, since it promotes muscle elongation. For example, specific applications include devices for improving motor function {for example, muscle elongation training (for example, stretching, yoga, muscle training); for track and field (for example, short distance, marathon, long jump), for ball games (for example, baseball, golf); for ice sports (for example, figure skating, jumping)}, and for rehabilitation (for example, lower back pain, frozen shoulder, stiff shoulder). Here, for example, in the case of golf, by using a glove with a Pacinian pressure part on the inside of the glove, it is expected that the correct form will be created and the arm will be raised higher. In addition, in the case of figure skating, it is expected that the number of rotations will increase if the palm of the hand is pressed against the Pacinian during practice (including practice until the day of the match, practice on the day of the match, and practice just before the match on the day of the match). The present invention can improve the performance of athletes, and can improve muscle flexibility without pain for ordinary people. In order to further realize the effects of the present invention, it is preferable to continue to press the Pacinian corpuscles for a predetermined period of time (for example, about 5 minutes).

[0044] It has also been confirmed that when the device according to the present invention is used, the effect continues for a while (for example, about 5 minutes) after use, and that even after use of the device is stopped, flexibility is maintained to the same extent as when the device was in use. Furthermore, it has also been confirmed that even if the device is not used for a long period of time (about several weeks) after use is stopped, and then used again after a long time, flexibility is maintained to the same extent as before use of the device was stopped.

[0045] As mentioned above, the device according to the present invention induces muscle relaxation. Therefore, the device according to the present invention can be used in areas other than exercise and rehabilitation, such as mental care. One example of the use of muscle relaxation is the "progressive muscle relaxation" method developed by Edmund Jacobson. This "progressive muscle relaxation" method is known as a method of inducing physical relaxation by repeatedly tensing and relaxing muscles. The following Internet site introduces "progressive muscle relaxation" as one of the relaxation methods for mental care. https: / / www.mext.go.jp / a_menu / shotou / clarinet / 002 / 003 / 010 / 004.htm

[0046] In addition, in order to improve symptoms of depression, social phobia, or insomnia, drugs are sometimes administered to relieve tension. For example, paragraph 0042 of Patent No. 6739846 states that "a patient (in her 30s, female) diagnosed with depression was plagued by social phobia and insomnia along with symptoms of depression, and had been prescribed intramuscular injections of Abilify (indication: depression) by a doctor at a psychiatric clinic, as well as Lexotan Tablet 2 (indication: anxiety and tension due to depression) and Brotizolam Tablet (indication: insomnia), but..." The device according to the present invention makes it possible to relieve tension without relying on drugs, and there is no need to worry about side effects from drugs. Furthermore, even if symptoms of developmental disorders (including autism spectrum disorder, attention deficit hyperactivity disorder (ADHD), learning disorders (learning disabilities), tic disorders, stuttering, etc.) are observed, it is possible to induce relaxation by inducing muscle relaxation and to expect relief of symptoms.

[0047] In addition, the Pacinian corpuscles are sensory receptors that detect pressure and vibration. Therefore, by vibrating the instrument, it is possible to stimulate the Pacinian corpuscles with vibrations associated with music, voice, and the like. Furthermore, it is possible to input stimuli such as the tempo, rhythm, melody, and strength of music through the Pacinian corpuscles into the body and transmit them to the brain. As a result, the brain is able to simultaneously perceive auditory information from the ears and bodily information from the Pacinian corpuscles. Furthermore, it is possible to fuse the senses of hearing and touch, and create a situation in which a person is given a sense other than the five senses (sight, hearing, smell, taste, and touch).

[0048] In addition, the Pacinian corpuscles receive vibrations of 100 to 400 Hz, and are most sensitive to vibrations of around 200 Hz. Furthermore, by using a sound source using a scale of a specific frequency, the Pacinian corpuscles can be effectively stimulated. Examples of the sound source include music composed only of a scale (scale frequency) of around 100 Hz to a scale of around 400 Hz, and music using a relatively large number of these scales (for example, more than half the number of scales or time). In addition, it is possible to compose new music or sound effects, or arrange (including modulation) existing music, so that the content is suitable for stimulating such Pacinian corpuscles. The term "vibration" in the present invention is a term that includes various vibration modes, such as a mode having a single frequency, a mode in which multiple frequencies are synthesized, a mode in which the vibration unit changes the pressing force, a mode in which pressing is performed at uneven time intervals or displacements, a mode of less than 1 Hz, a mode in which pressing is performed while vibrating, or a mode by a combination of these. EXAMPLES

[0049] (Objective of this Example) In this example, a test was conducted using the grip (the device 1 described with reference to Figs. 1 to 5) on the following eight men and women of different ages (hereinafter referred to as subjects) in the following manner.

[0050] (subject) Randomly selected men and women (8 people in total) in their 20s to 70s were measured. 1 woman in her 20s 2 men, 1 woman in their 30s 1 man, 2 women in their 40s 1 woman in her 70s The attributes of the subjects measured in this study are shown in Table 1 below. [Table 1]

[0051] (Measurement method 1) The subjects were asked to perform three types of measurement exercises (side bending, leg lifting, and waist twisting) under three conditions: manual (not holding anything), bar grip (holding a bar), and grip grip (holding a grip), and were asked about muscle pain and stretching during muscle stretching. As a result, it was confirmed that for all three types of measurement exercises (side bending, leg lifting, and waist twisting), muscle pain and stretching during muscle stretching was lower for all subjects when using grip grip compared to manual and bar gripping.

[0052] (Measurement method 2) The subject stood in a designated position and three types of measurement movements (side bending, leg lift, and waist twisting) were recorded with video cameras (camera 1 and camera 2), and the angles of the range of motion of the joints were measured when using the bare hand (not holding anything), when holding a stick (holding a stick), and when holding a grip (holding a grip). For the measurements, a mat was placed on the floor to fix the position of the subject's feet. The video cameras were set up in front of and to the side of the subject (see Figure 9).

[0053] Specifically, the subjects were measured according to the following procedure. The subject stands along a predetermined foot position reference line and performs three types of measurement exercises. (Camera 1) Camera 1 captured images of the subject's range of joint motion during various exercises, and the data was used to confirm the expansion of the range of joint motion. (Camera 2) Camera 2 was used to capture the various exercises from the side of the subject, and it was possible to confirm from the side whether the subject's foot position was correct during exercise, as well as to confirm that the subject's body was at the correct angle during each exercise.

[0054] (Type of exercise to measure effectiveness) The exercises used to measure the effects (hereafter referred to as measurement exercises) were three types, namely, side bending, leg raising, and waist twisting, performed on both the left and right sides (see Figure 10).

[0055] (Foot positioning) The subject's distance from camera 1 was kept constant, and the subject was positioned so that he or she was standing perpendicular to the line of sight of camera 1 as follows. (a) Foot position for lateral bending and twisting (see Figure 11) The subject's shoe was placed in a standing position with the tip of the toe aligned with the foot positioning line. The foot width was determined by dividing the vertical center line (CL) into two widths to allow each subject to easily move. During the test, tape T was attached to the tip of the shoe and to the floor in a position determined by the subject, as shown in the figure, so that the subject could return to the original position if the foot shifted during the test. The footage from Camera 1 was used to check whether the subject's standing position was correct during the movement measurement, and a decision was made as to whether the data could be used.

[0056] (b) Foot position when raising the leg (see Fig. 12) The subject stood with the heel of the shoe of the foot to be raised and the side of the shoe aligned with line L, which is indicated as the foot position reference line. After determining the position of the foot to be raised, the subject's supporting foot was set so that it was attached to the shoe to be raised, and the heel was positioned along the frame indicated by line L. The subjects checked their foot position each time they performed the leg-raising exercise. Whether the subject's foot position was correct during the movement measurement was confirmed by looking at the image from Camera 2, and a decision was made as to whether the data could be used.

[0057] (Measurement Procedure) (a) Subjects were asked to gather individually at set times. (b) The purpose of the measurements, the purpose of use of the data, safety management, and any risks were fully explained to the subjects. (c) The location of the subject's Pacinian corpuscles was detected and marked with a marker using the method described below (see Detection of the Location of Pacinian Corpuscles below). (d) Before the test, participants were asked to do about five minutes of warm-up exercises to prepare their bodies. (e) After the warm-up exercise was completed, the measurement exercise began immediately.

[0058] (Detection of the location of Pacinian corpuscles in the palm) As mentioned above, the Pacinian corpuscles in the palm are one of the mechanical receptors found in the skin, and as illustrated in Figure 1, they are located on the tip of the middle finger and in the palm below the little finger, and are pressure-detecting joints.

[0059] (Detection of the position of the Pacinian corpuscle in the middle finger: see Figure 13(a)) The location is easy to detect because it is located on the tip of the middle finger, and the test was performed to help the patient recognize the throbbing sensation felt when pressing on the Pacinian corpuscle. (a) The subject was asked to use an acupressure stick to stimulate the pad side of the middle finger in different locations and feel the difference in stimulation when pressed with the acupressure stick. (b) Next, the center of the pad side of the tip of the middle finger (first joint) was pressed slowly and quickly with an acupressure stick to detect the area of ​​sharp pain. (c) Next, the area of ​​pain (Pacinian point) was marked with a marker.

[0060] (Detection of the location of the Pacinian corpuscles in the palm: see Figure 13(b)) In the measurements of this example, Pacinian corpuscles were detected in the palm of the hand that was pressed. (a) The subject was asked to stimulate the palm of his / her hand using a pressure point pressing stick at different locations and feel the difference in stimulation when pressed with the pressure point pressing stick. (b) Next, the center of the palm on the little finger side was pressed slowly and quickly with the acupressure stick to detect the spot where a sharp pain similar to that felt with the middle finger was felt. (c) Next, the area of ​​pain (Pacinian point) was marked with a marker. In addition, the Pacinian corpuscles were located in approximately the same position on the palm of the hand, on the tip of the middle finger, in all subjects.

[0061] Figure 14 shows the images of the positions of the Pacinian corpuscles in the palms of the hands of each subject. Note that the marks made with a magic marker are difficult to see in the image of Figure 14, so they have been circled.

[0062] (measurement) (a) At the point where the angle of each movement was maximum, two remote controls were operated simultaneously to take pictures of Camera 1 and Camera 2 in rapid succession so as not to shake the cameras. Approximately 30 pictures were taken at a time. (b) While performing manual, rod, and grip gripping, the experimenter made sure that the subject did not move from the designated position to prevent deviations in the body position (especially the position of the feet). The experimenter also made sure that the grip was properly placed on the Pacinian corpuscles and ensured that the grip was held in the designated position. (c) There was a three-minute interval between each of the three types of exercise, and the subjects completed each exercise. It should be noted that, after each exercise, it was confirmed that the pressing portion 20 of the device 1 was reliably contacting (pressing) the location of the Pacinian corpuscles on the palm of the subject's hand.

[0063] (Provision of the origin) The origin of the subject's body (the origin for measuring the effect of increasing joint range of motion) was defined as follows: First, the absolute coordinates are defined as follows: (a) The floor is zero and the upward direction is positive. (b) The vertical axis center line CL is set to zero, and the rightward direction is positive and the leftward direction is negative.

[0064] (Grid origin) In addition, for use in measurements, a position on the vertical axis center line (CL) at a position 150 cm from the floor surface was defined as the grid origin.

[0065] (Subject's body origin) The following origin was defined as the starting point for measuring the effect of increasing joint range of motion. · Origin of leg lift right · Left leg lift origin Origin of lateral bending left and right

[0066] Below is the idea of ​​the origin of the body. (a) Draw the center line of each subject's foot. Also, draw a vertical line L1 through the approximate center of the body at the location that is thought to be the femoral joint (see Figure 15(a)). (b) The point where the line L2 passing through the center of the foot intersects with the line L1 is set as the origin of the left leg (see Figure 15(b)). (c) The position symmetrical about the vertical axis center line CL of the origin of the left leg-raised body is the origin of the right leg-raised body, and the point where it intersects with the vertical axis center line CL at the height of the origin of the right leg-raised body is the origin of the lateral bending body (see Figure 15(c)).

[0067] Next, the procedure for obtaining the measurement results will be described. The measurements for each movement were compared with respect to the origin of the body (see Figure 16). (a) From the measured images, select the image that shows the maximum performance for each exercise. (b) Using the illustration function, extract only the human body from the image and paste it as image data into PowerPoint (registered trademark) (hereinafter referred to as PPT). (c) The PPT function pastes the image at the center of the PPT screen, filling the top and bottom of the screen. This pastes all the pasted images at the center of the PPT screen at the same scale. Therefore, the grid origin of each image is in the same position on the PPT screen, allowing accurate comparison.

[0068] How to compare the dimensions of the manual and gripping grips (see Figure 17) (a) The image pasted on the PowerPoint was projected onto a 65-inch high-definition LCD monitor, tracing paper was attached to the screen, the origin was determined, and the dimensions of each measurement point and line copied onto the tracing paper were measured using a ruler and protractor. (b) Measurement results were converted to actual size at the following magnifications: In addition, when a box with a 600 mm square was measured on a 65-inch screen, it was 167 mm. From this, the measurement magnification of the screen was calculated as 600 / 167 = 3.593 times.

[0069] Results of lateral bending (data was compiled in the same manner for leg lift and waist twist) (see Figure 18) (a) Identify the body origin mentioned above (in Figure 18, the body origin for lateral bending). (b) Place a point with a pencil at the center of the elbow joint on the tracing paper. On the computer PowerPoint, place a point on the right angle of the white triangle to match that point. (c) Draw a straight line (vertical center line) from the origin of the body in lateral bending to the point. (d) The angle of trunk flexion away from the vertical center line CL is the range of motion of the lateral bending joint during manual manipulation. (e) Using the same procedure as for manual gripping, determine the joint movement angle from the origin when gripping (see Figure 19).

[0070] (Comparison between bare hand and grip) (a) Using the illustration function, the image of the grip is processed to extract only the human body. (b) Paste the extracted image above on top of the image of the bare hand. All images of the human body only pasted in the PPT are extracted to the same scale and origin. Therefore, even if the image of the gripping hand is pasted onto the image of the bare hand, the exact origin and scale are maintained, resulting in an accurate comparison (see Figure 20). The comparison between the bare hand and the stick grip was also performed using the same procedure.

[0071] (Comparison image of measurement results) (lateral bending) Lateral bending is an exercise that bends the side of the body. The exercise is performed by standing on the floor with the body straight, raising the right arm straight up so that it is parallel to the vertical axis center line, and bending the side by leaning only the upper body to the left or right without moving the lower body from the waist, as shown in the image below. In this example, the vertical axis center line and the origin of lateral bending are used as axes to perform lateral bending, and the inclination angle of the trunk when using the bare hand (θ1), the inclination angle of the trunk when holding a stick (θ2), and the inclination angle of the trunk when holding a grip (θ3) are measured, and the differences are compared. Note that Figure 21 shows images of the inclination angle of the trunk when using the bare hand (dotted line) and the inclination angle of the trunk when holding a grip (solid line).

[0072] (legs up) The leg lift is an exercise in which the body is raised upright with both feet together, and the left or right leg is raised forward without any recoil, as shown in the image. In this embodiment, the flexion angle (θ1) between the pivot leg and the lifting leg when using a hand, the flexion angle (θ2) between the pivot leg and the lifting leg when using a stick, and the flexion angle (θ3) between the pivot leg and the lifting leg when using a grip were measured from the origin of the leg lift, and the differences were compared. Note that FIG. 22 shows images of the flexion angle (θ1) between the pivot leg and the lifting leg when using a hand (dotted line) and the flexion angle (θ3) between the pivot leg and the lifting leg when using a grip (solid line).

[0073] (Waist twist) The waist twist is an exercise in which the subject stands with the body straight, bends forward as much as possible, does not move from the waist down, points the left hand toward the positioning tape of the right shoe, and slowly raises the right hand toward the vertical axis center line from the state of being stretched straight down, twisting the body using only the upper body. In this example, the twisting angle (θ1) when using the hand, the twisting angle (θ2) when using the rod grip, and the twisting angle (θ3) when using the grip grip were measured with the intersection of the perpendicular line of the vertical axis center line and the twisting angle line as the center, and the differences were compared. Note that Figure 23 shows images of the twisting angle (θ1) when using the hand (dotted line) and the twisting angle (θ3) when using the grip grip (dotted line).

[0074] (Comparison results) For reference, measurement images of side bending, leg lifting and waist twisting are shown in Fig. 24 to Fig. 26. Fig. 24(a) is an image of side bending left, and Fig. 24(b) is an image of side bending right. Fig. 25(a) is an image of leg lifting left, and Fig. 25(b) is an image of leg lifting right. Fig. 26(a) is an image of waist twisting left, and Fig. 26(b) is an image of waist twisting right. In addition to measurement images of the "stick" and "grip (instrument 1)", Fig. 24 to Fig. 26 also show measurement images of the manual hand.

[0075] (Comparison between manual and tool (grip)) FIG. 27 is a diagram showing the measurement results and the difference (Δθ1) between the angle (θ1) measured with the “manual” and the angle (θ3) measured with the “grip (instrument 1)” as described above. As shown in Figure 27, although there are differences in the degree, the angle is larger when gripping the grip (instrument 1) than when gripping the bare hand for all subjects 1 to 8, and it is understood that the range of motion of the joint is expanded. Note that only subject 7's right waist twist has a negative value of θ3, but this is a slight difference and does not affect the results of this measurement, so it can be said that the effect of the grip (instrument 1) of the present invention is clear.

[0076] (Comparison between stick and tool (grip)) FIG. 28 is a diagram showing the measurement results and the difference (Δθ2) of the angle (θ2) when holding the “stick” and the angle (θ3) when holding the “grip (instrument 1)” measured as described above. As shown in Figure 28, although there were differences in degree, for all subjects 1 to 8, the angle was larger when gripping the grip (instrument 1) than when gripping the stick, indicating that the range of motion of the joints was increased. In addition, when gripping a stick, the range of motion of the joints is slightly greater than when using bare hands, but the difference in the effect of increasing the range of motion of the joints when gripping a grip (Equipment 1) is clear. This is thought to be because, whereas when gripping a stick, it is easier to apply force and it appears as if the range of motion of the joints is expanded due to muscle strength, when pressure is applied to the Pacinian corpuscles by gripping, muscle pain is eliminated and the range of motion of the joints is expanded, as described in the "Discussion" section below, which is a fundamentally different action and effect. Subject 6 was the first subject in the test, and the recording of the right leg lift was not done well. For the other subjects, the recording and measurement were done well, and the effect was also remarkable. Therefore, the lack of data for Subject 6 did not affect the results of this measurement, and it can be said that the effect of the grip (instrument 1) of the present invention is clear.

[0077] (Comparing bare hands and a stick) FIG. 29 is a diagram showing the measurement results of the angle (θ1) when "handled" and the angle (θ2) when "stick" is gripped, as described above, and the difference (Δθ4). As shown in Figure 29, there were some subjects whose angle was larger when they gripped the stick than when they gripped their bare hands, but the difference was small, and the difference in the effect of increasing the range of motion of the joints when gripping the grip (Apparatus 1) was clear. This is thought to be because, as mentioned above, when gripping a stick, it is easy to apply force, so it appears as if the range of motion of the joints is expanded due to muscle strength, whereas when pressure is applied to the Pacinian corpuscles by gripping, muscle pain is eliminated, as described in the "Discussion" section below, so the range of motion of the joints is expanded, resulting in a fundamentally different action and effect. Regarding subject 6's right leg lift, he was the first subject and we were unable to photograph him, so measurements could not be taken.

[0078] (Consideration) As described above, it was found that applying the right pressure to the exact location of the Pacinian corpuscles in the palm of the hand with a projection of the right shape relieves muscle tension throughout the body and causes muscle relaxation. It was also found that muscle relaxation increases the flexibility of the entire body, resulting in an increase in the range of motion of the joints.

[0079] Furthermore, other measurements (not shown) made by the inventors showed that the muscle relaxant effect was cross-sectional between the left and right sides. For example, when the device was held in the right hand, muscle relaxation was more pronounced in the muscles on the left side of the body. In contrast, when the device was held in the left hand, muscle relaxation was more pronounced in the muscles on the right side of the body.

[0080] Taking the side bending exercises shown in Figures 24(a) and (b) as an example, when holding the tool in the right hand and performing left side bending (using Figure 24(a)), the flexibility of the body was increased compared to when holding the tool in the left hand and performing the same left side bending. Conversely, when holding the tool in the left hand and performing right side bending (using Figure 24(b)), the flexibility of the body was increased compared to when holding the tool in the right hand and performing the same right side bending.

[0081] [Second embodiment of the device] Next, a second embodiment of the tool will be described. Figures 31 and 32 show a tool 200 (grip) of the second embodiment. The main difference between the tool 200 of the second embodiment and the tool 1 described so far (illustrated in Figures 1 and 8) is that the tool 200 of the second embodiment is a ring model. The name "ring model" here means that it has a ring (finger locking part) that locks onto the user's finger.

[0082] (Configuration of the device 200) The configuration of an instrument 200 according to the second embodiment will be described with reference to Figures 31 and 32. Note that descriptions of structures and functions similar to those of the above-described instrument 1 will be omitted as appropriate. Like the above-described instrument 1, the instrument 200 according to the second embodiment is designed to apply pressure stimulation to accurate positions of the Pacinian corpuscles to increase the range of motion of the joints.

[0083] The device 200 includes a main body 210 to be held by a user, a pressing portion 220 protruding from the main body 210, and a ring portion 230 into which the user inserts his or her little finger and ring finger. In Fig. 31 and Fig. 32, the main body 210 has a rectangular parallelepiped shape with chamfered corners.

[0084] The ring portion 230 is fixed to the main body portion 210. When the ring portion 230 and the main body portion 210 are molded separately, various general fixing methods can be adopted for fixing the ring portion 230 to the main body portion 210. For example, it is conceivable to press-fit the ring portion 230 to the main body portion 210, fix it using a general screw (fixing screw), or fix it by adopting an engaging claw structure.

[0085] Two rings, a pinky ring 231 for the pinky finger and a ring finger ring 232 for the ring finger, are formed side by side in the ring portion 230, and these pinky ring 231 and ring finger ring 232 will be described later. It is also possible to integrally mold (synthetic resin mold) the ring portion 230 with the main body portion 210. In this embodiment, the main body portion 210, the pressing portion 220, the ring portion 230, and the shaft portion (connecting portion) 222 described later are made by integral molding of synthetic resin.

[0086] The pressing part 220 has a shaft part 222 that functions as a connection part, and is fixed to the main body part 210 with the shaft part 222 inserted into the main body part 210. Various general fixing methods can be adopted for fixing the pressing part 220. For example, the shaft part 222 may be press-fitted into the main body part 210, may be fixed using a general screw (fixing screw), or may be fixed by adopting an engaging claw structure. It is also possible to integrally mold the pressing part 220 with the main body part 210 (molded from synthetic resin).

[0087] The shape of the main body 210 is not limited to a rectangular parallelepiped. Various shapes of the main body 210 can be adopted in consideration of ease of gripping, improved functionality, and the like. For example, the main body 210 may be appropriately provided with projections and recesses in consideration of ease of gripping, weight reduction, and the like. Furthermore, the shape of the main body 210 may be asymmetrical, character-shaped (for example, various alphabet types, katakana type, hiragana type, etc.), or symbol-shaped in consideration of design.

[0088] When the main body 210 is held by the user, the pressing portion 220 presses and stimulates the Pacinian corpuscles present in the palm of the user's hand. The pressing portion 220 includes a contact portion 221 (Pacinian ball). The contact portion 221 has a contact surface 221a that contacts the Pacinian corpuscles, and is integrated with the shaft portion 222.

[0089] Here, the contact portion 221 has a shape that allows pinpoint pressure on only the Pacinian corpuscles (in this embodiment, it is ball-shaped, but it is sufficient that only the Pacinian corpuscles can be pinpoint-pressed, and other shapes are acceptable) (it is preferable that the shape does not stimulate (cannot be touched or is difficult to touch) anything other than the Pacinian corpuscles). This point will be described later as a modified example (FIGS. 36 and 37).

[0090] The shaft portion 222 connects the main body portion 210 and the contact portion 221. The shaft portion 222 also has a function of separating the main body portion 210 and the contact portion 221 from the palm of the user when the main body portion 210 is held by the user.

[0091] In the following description, as shown in Figures 31 and 32, the direction in which pressing portion 220 protrudes relative to main body portion 210 is defined as the Z-axis direction, the direction in which ring portion 230 protrudes relative to main body portion 210 is defined as the X-axis direction, and the direction perpendicular to these X-axis and Z-axis directions is defined as the Y-axis direction.

[0092] As described above, two rings, the little finger ring 231 and the ring finger ring 232, are formed side by side on the ring unit 230. The user inserts the little finger into the little finger ring 231 and the ring finger into the ring finger ring 232, and wraps the main body unit 210 around the inside of the palm with the pressing unit 220 facing the palm (FIG. 33).

[0093] The positional relationship of each part of the device 200 is designed so that, when the user grips the device 200, the abutment part 221 at the tip of the pressing part 220 comes to a position where the Pacinian corpuscles are in contact with the device 200. The gripping force of the little finger in the little finger ring 231 and the supplementary gripping force of the ring finger in the ring finger ring 232 press the Pacinian corpuscles with the abutment surface 221a of the abutment part 221, stimulating them.

[0094] The contact portion 221 has a spherical shape that allows pinpoint pressure on only the Pacinian corpuscles (preferably a shape that does not stimulate (cannot touch or is difficult to touch) anything other than the Pacinian corpuscles). In other words, when the instrument 200 is used, it is preferable that a space is formed around the contact portion 221, as with the instrument 1 of the first embodiment. In other words, it is preferable that a region where the instrument 200 does not contact the palm (non-contact region) is formed outside the region where the contact portion 221 contacts the palm (contact region) so as to surround the contact region.

[0095] Such a ring model instrument (instrument 200 in this example) can also be described as follows: The most difficult aspect (or one of the most difficult aspects) of an instrument capable of pressing the Pacinian corpuscles is to prevent the sphere (Pacinian ball) from shifting from its correct position in the palm of the hand due to rotation or slippage.

[0096] In other words, when developing this type of instrument, it is extremely important to place the sphere accurately at the Pacinian point (the position where the Pacinian corpuscles can be pressed accurately, also known as the Pacinian position) in the palm of the hand holding the instrument, and then to ensure that the position of the Pacinian ball does not shift from its exact position due to the force of pressure or the movement of the fingers.

[0097] In the device 1 of the first embodiment illustrated in Figures 1 and 8, as shown in Figures 3 to 7, the second stopper 11B and third stopper 11C are used to fix the grip position at three points: the thumb, index finger, and the Pacinian ball on the palm, and the palm is pressed by the force of the little finger and ring finger.

[0098] In contrast, in the device 200 of the second embodiment, the main body portion 210 (grip) is positioned in the palm of the hand by three points: the little finger ring 231 attached to the main body portion 210, the little finger pressing portion (the portion of the main body portion 210 that is pressed by the little finger), and the abutment portion 221 (Pacinian ball) of the pressing portion 220, so that the abutment portion 221 is accurately fixed to the position of the Pacinian corpuscles.

[0099] Fig. 33 shows a state where the ring model instrument 200 is held in the left hand. However, the instrument 200 shown in Fig. 33 is a schematic illustration of a prototype of the instrument 200 shown in Figs. 31 and 32 to facilitate illustrating the positional relationship. Therefore, although the shape does not match that of the instrument 200 shown in Figs. 31 and 32, it has portions corresponding to the main body portion 210 and the ring portion 230. In Fig. 33, these portions are denoted by the reference numerals 210 and 230.

[0100] The position of the Pacinian corpuscles on the palm (point P, which is the Pacinian point) is located almost directly below the first joint of the little finger (the fingertip in Fig. 33) when the little finger is naturally bent in a bow shape as shown in Fig. 33. In this embodiment, a ring part (little finger ring 231) is provided in a position of main body part 210 facing the base of the little finger (the third joint), thereby realizing the following functions.

[0101] That is, in the device 200, the position of the little finger is restricted by the little finger ring 231. Therefore, when the little finger is naturally bent, the distance (distance L in the X-axis direction) between the position of the third joint of the little finger (position A on the little finger ring 231 in FIG. 33, indicated by a circle) and the imaginary tip of the pressing part 220 (point C indicated by a triangle, or Pacinian point P indicated by an oval) is kept constant. Therefore, the pressing part 220 of the main body 210 accurately hits the Pacinian point (point P).

[0102] In addition, the angle θ (θ°) between the ring part 230 and the main body part 210 is fixed, the part pressed by the little finger (point B, indicated by a triangular mark) and the pressing part 220 are aligned on the arc (D) formed by the little finger and the palm, and the pressing force of the little finger acts accurately as pressure on the Pacinian corpuscles. Furthermore, point B is aligned almost exactly on the same line as the above-mentioned points C and P.

[0103] The pressure force (pressing force, shown by arrow F) on the Pacinian corpuscles is generated by the little finger and ring finger (mainly the little finger). When the main body portion 210, whose position is restricted by the ring portion 230, is pressed mainly by the force of the little finger, the pressing portion 220 (tip at point C) is pushed into the palm by the axial force. In addition, a frictional force is generated between the main body portion 210 and the palm by the force of the little finger etc. pressing almost directly from above. Then, the force from almost directly above and the restriction by the ring portion 230 combine to suppress the left and right rotation of the instrument 200 (left and right rotation, which is a displacement around the Z axis), as shown in FIG. 33.

[0104] Therefore, when the user grasps the main body 210, the instrument 200 is affected by the pressure of the little finger and the ring finger and does not move in any direction, but is stably fixed in an accurate position. Then, the pressure force F acts directly on the Pacinian corpuscles. Furthermore, the instrument 200 is supported at three points, the little finger ring 231 (point A), the part pressed by the little finger (point B), and the pressing part 220 (point C), so that the angle θ between the little finger and the palm is maintained and the instrument 200 is stably fixed in an accurate position. Then, compared with the instrument 1 of the first embodiment, it becomes easier to perform accurate pressing of the Pacinian corpuscles.

[0105] In order to fix the main body part 210, it is sufficient that the first joint on the tip side of the little finger is in contact with the main body part 210 at point B. It is desirable to determine the shape and dimensions (size) of the main body part 210 and the relationship with the little finger so that a gap (gap 882 in the referenced FIG. 52) can be secured between the little finger and the main body part 210 at points other than point B. By floating the little finger (the portion from point B to the base side) above the main body part 210, a space for moving the little finger can be secured, and the force applied from the little finger to the main body part 210 can be easily adjusted.

[0106] (Effect when using the device 200) According to the ring model device 200 as described above, it is possible to expand the range of motion of a joint to the same extent as the device 1 of the first embodiment (illustrated in Figs. 1 and 8). Fig. 34 shows the results of an experiment on the effect of expanding the range of motion of a joint by the device 200. For comparison, a type without a ring portion (called the "Nike model"), as shown in a different orientation in Figs. 63(a) and (b), was used. This type has the basic functions of the device 1 of the first embodiment shown in Figs. 1 and 8, and has a main body portion 10 and a pressing portion 20 like the device 1.

[0107] As a result of an experiment on the effect of expanding the range of motion of a joint using the Nike model shown in Fig. 63 and the ring model (instrument 200) shown in Fig. 31, it was confirmed that the range of motion of the joint can be expanded to the same extent with both models if there is no difference in the pressing force of the pressing parts (20, 220) (see Fig. 34). From the top to the bottom, Fig. 34 shows photographic images of lateral bending in the case of bare hands (not holding anything), when using the Nike model, and when using the ring model.

[0108] According to Figure 34, in the case of bare hands (upper image), the subject's right arm stops at a position higher than horizontal. In contrast, when the Nike model (middle image) and the Ring model (lower image) are used, the subject's right arm reaches a position lower than horizontal to the same extent.

[0109] As mentioned above, with regard to misalignment in the rotational direction, by providing the ring portion 230, rotation around the Z axis (left and right rotation) can be prevented, making it easier to accurately press the Pacinian corpuscles than with the instrument 1 of the first embodiment.

[0110] [Application] As long as no trouble occurs, the tool 200 can be used for various purposes such as for improving athletic function, for track and field, for ice sports, for rehabilitation, etc., in the same manner as the tool 1 of the first embodiment (illustrated in Figs. 1 and 8, etc.). In addition, the uses of the ring model tool 200 can be explained as follows.

[0111] For example, when an athlete or professional athlete is performing serious exercise, it is considered that it is more suitable for the angle between the thumb and index finger to be restricted. Also, for example, if the hand is opened for some reason while holding the device 1 of the first embodiment and exercising, the device 1 falls and is likely to be damaged. However, in the ring model device 200, the fingers are passed through the ring portion 230 and are engaged with the ring portion 230, so the device 200 does not fall even if the palm of the hand is opened. In other words, the ring model does not easily fall from the palm of the hand even if the hand is opened, because there is a ring on the little finger (little finger ring 231).

[0112] Furthermore, the three fingers, the thumb, index finger, and middle finger, are not restricted by the ring portion 230 and can be moved freely while using the device 200. Therefore, the effect on movement is kept to a minimum.

[0113] Furthermore, the ring model tool 200 can be held by the little finger, ring finger, and palm, and there is no need to extend the main body 210 to the thumb or index finger, so it is small and easy to carry. Because it is easy to carry, for example, when an ordinary person performs daily exercises, walking, jogging, hiking, etc., the effect (grip effect) of the tool 200 causes muscle relaxation of the entire body, making it easier to obtain a sense of an expanded range of motion in the joints on a daily basis. Furthermore, compared to performing these actions without gripping the tool 200, the effect of lifting the legs is obtained more comfortably, and it becomes possible to feel a sense of lightness in the entire body more regularly.

[0114] Generally, there are individual differences in the size and shape of the palm, the shape and length of the fingers, and the location of the Pacinian point. In addition, the size of the hand and the Pacinian point of children change almost every year as they grow. For this reason, the most effective results can be achieved by creating a device (personal grip) that is shaped and sized to fit the palm of the person's hand according to individual differences or according to age and generation.

[0115] [Modifications Related to Ring Portion 230] Next, modified examples of the ring portion 230 in the above-mentioned ring model instrument 200 will be described. All of the modified examples of the ring portion 230 described here can be manufactured by integral molding of synthetic resin. Also, they can be manufactured by the above-mentioned automated design.

[0116] The function of the ring model tool 200 as described above can be achieved in the same manner even if the shape of the ring portion 230 is changed. FIG. 35 illustrates various shapes that can be adopted for the ring portion 230. FIG. 35(a) illustrates a tool 200 similar to that shown in FIG. 31 and FIG. 32, and this tool 200 includes a ring portion 230 in which two rings (a pinky ring 231 and an annular ring 232) are formed as described above. Hereinafter, this type is considered as the standard type for the ring portion 230.

[0117] It should be noted that the device 200 shown in Figure 35(a) is turned upside down with the pressing portion 220 facing forward compared to the device 200 shown in Figure 32, and the positional relationship between the main body portion 210 and the ring portion 230 is also slightly different.

[0118] In contrast to this standard type, Fig. 35(b) shows a type of ring part 230b in which the partition wall between two rings (pinky ring 231 and ring finger ring 232) is partially removed to connect the internal spaces of the two rings 231 and 232 into one. Fig. 35(c) shows a type of ring part 230c having only one ring (pinky ring 231 in this case).

[0119] Figures 35(d)-(f) show a type in which the tip side of the ring parts 231a-231c in Figures 35(a)-(c) is cut obliquely (here, so as to become lower from the ring finger side to the little finger side) with respect to the Y axis (shown in Figure 35(a)), and the shape of the ring (231 or 232) is an open arc shape (W-shape or U-shape). And, the instruments 200b-200f equipped with these types of ring parts 230b-230f can also prevent rotation around the Z axis (left and right rotation), and can exhibit the same position fixing function as the instrument 200 of this embodiment.

[0120] [Modifications Related to Pressing Section 220] Next, there will be described various modified examples relating to the pressing portion 220 of the device 200. Note that the same parts as those of the device 200 of the second embodiment are given the same reference numerals, and the description thereof will be omitted as appropriate.

[0121] (First Modification of Pressing Part 220) In the first embodiment described above, it has been explained that it is preferable to form a space around the contact part 21 (Pacinian ball) of the pressing part 20 of the instrument 1 so as not to stimulate sensory receptors other than the Pacinian corpuscles when the contact part 21 (Pacinian ball) is sunk into the palm by about 1 mm to 15 mm (preferably 3 to 10 mm) as shown in Fig. 5. In relation to this, in the instrument 200A of the second embodiment shown in Fig. 36, the radius R of the spherical pressing part 220A (particularly the contact part 221) is optimized.

[0122] For example, if the entire (or most) part of the pressing part 220 (here, 220A) or the contact part 221 (here, 221A) is spherical, if the radius of the sphere is too large, the arc (spherical surface) of the contact part 221A that contacts and presses against the palm of the hand will also be large. Then, the arc (spherical surface) that presses the Pacinian will become larger, and the shape of that part will approach a flat surface. As a result, if the Pacinian point is set to a small radius of about 1 mm, it will be difficult to press the Pacinian point accurately with an appropriate amount of force.

[0123] Also, if the radius of the contact portion 221A is too small, the pressing force will cause the pressing portion 220 (here, 220A) to sink too far into the palm, causing the user to feel pain. In this case, it becomes difficult to transmit an appropriate pressing force to the Pacinian corpuscles. Also, the size of the palm of each individual is usually different for each element (attribute) such as an adult, child, woman, or man, and the radius at which the pressure of the contact portion 221 (Pacinian ball) is appropriately felt is different.

[0124] Considering these factors, it is most effective for the contact portion 221A to have a spherical shape, as in the device 1 and device 200 described above. In addition, in the example of FIG. 35, the radius R of the contact portion 221A is set to any value within the range of R4 to 10. For example, within this range, when the radius is set to R4, the contact portion 221A suitable for a female child (girl) is obtained. Also, when the radius is set to R10, the contact portion 221A suitable for an adult male (adult man) is obtained. According to the research by the inventors, for an average-sized Japanese adult female, R7 to 8 is suitable, and for a larger-sized person, about R8 to 10 is suitable. Also, for a person smaller than the average-sized Japanese female, about R4 to 7 is suitable.

[0125] (Second Modification of Pressing Part 220) 37(a) and (b) show an enlarged view of the pressing portion 220B according to the second modification. In this pressing portion 220B, the contact portion 221B formed integrally with the pressing portion 220B has a raised convex shape. The contact portion 221B has a stepped shape (here, a two-step shape), and has a semispherical first contact portion 221B1 (the tip of the pressing portion 220B) having a relatively small radius, and a tapered second contact portion 221B2 having a relatively large radius. In the example of FIG. 37, the pressing portion 220B has a three-step shape as a whole, including the second contact portion 221B2. In addition, in FIG. 37(a) and (b), the angle of the taper in the second contact portion 221B2 changes slightly midway, so a ring-shaped line is drawn in the middle of the second contact portion 221B2.

[0126] As shown in Fig. 37(b), the base end side of the pressing part 220B (the side of the shaft part 222 shown in Fig. 31) is molded flat, and the shaft part 222 (Fig. 31) is fixed to this flat part. The part of the pressing part 220B excluding the first contact part 221B1 and the second contact part 221B2 is molded into a spherical shape, and the radius R A For example, the size is about R4 to R10.

[0127] Radius R of the first contact portion 221B1 B R is about 0.5 to 5 (R A The tip side of the second contact portion 221B2 is a small-diameter portion that is continuously connected to the first contact portion 221B1, and the radius R C (Horizontal radius in the drawing) is the radius R of the first contact portion 221B1 B The base end side of the second contact portion 221B2 is a portion on the large diameter side, and the radius R D is R A It is a smaller value than

[0128] By making the shape of the pressing part 220B a multi-stage sphere as shown in Fig. 37(a) and (b), a stronger stimulation can be directly applied to the precise Pacinian point using the first contact part 221B1 at the tip. Furthermore, the first contact part 221B1 at the tip allows the pressing part 220B to be satisfactorily inserted into the palm of the hand. As a result, the contact part 221B (Pacinian ball) is prevented from slipping, and the contact part 221B (Pacinian ball) can be prevented from slipping and moving even if the user changes his / her posture during exercise.

[0129] The shape of this second modified example allows the first contact portion 221B1 to function like a pivot, making it possible to continue to press accurately on the Pacinian point without it shifting position. As mentioned above, the Pacinian corpuscles are sensory receptors measuring about 1 mm in size, so preventing the position of the pressing portion 220B from shifting is important for accurately stimulating the Pacinian point. Also, if the diameter of the first contact portion 221B1 is excessively small, there is a possibility that excessive pain will be felt when pressing. For this reason, the radius R BIt is preferable that R is about 0.5 to 5.

[0130] In the second modification, the portions of the pressing portion 220B other than the first contact portion 221B1 (the portion closer to the base end than the first contact portion 221B1, particularly the second contact portion 221B2) are larger than the first contact portion 221B1. Therefore, when the first contact portion 221B1 presses the palm, the second contact portion 221B2 located closer to the base end than the first contact portion 221B1 and the like function as a stopper. This prevents excessive sinking or pressure from occurring when pressing.

[0131] It is also possible to determine an appropriate degree of pressure based on the contact area between the pressing portion 220B (particularly the first contact portion 221B1 and the second contact portion 221B2) and the palm. The size of the first contact portion 221B1 and the second contact portion 221B2 can be determined so that this contact area falls within an appropriate value (or range).

[0132] The shape of the first contact portion 221B1 (the tip of the pressing portion 220B) may be a shape other than a spherical shape (including a curved shape), such as a cone shape or a pyramid shape, as long as it is not excessively sharp. In FIG. 37, auxiliary lines (auxiliary lines) connecting the tip to the base end are drawn at 90 degree intervals in the circumferential direction on the outer circumferential surface to make it easier to understand the three-dimensional shape of the pressing portion 220B. FIG. 38(a) illustrates a first contact portion 221B11 that is cone-shaped and further has a curved tip portion (which may be a spherical tip). In this case, the curved surface of the first contact portion 221B11 can be a curved surface equivalent to a spherical surface with R0.5 to 5.

[0133] Furthermore, the shape of the tip of the first contact portion 221B1 is not limited to a spherical shape (including a curved shape), and for example, as shown in FIG. 38(b) of the first contact portion 221B12, the whole may be cylindrical, and the tip may be a flat surface. Furthermore, the tip of the first contact portion 221B12 shown in FIG. 38(b) may be curved (or may be a true sphere). In this case, too, the curved surface of the first contact portion 221B12 may be a curved surface approximately equal to a true sphere of R0.5 to 5. Although not shown, the tip of the first contact portion 221B1 may be a polyhedron (including a regular polyhedron), a sphere with needles (including a curved surface, a sphere with needles is also called a "star sphere"), or the like.

[0134] (Third Modification of Pressing Part 220) Fig. 39 shows a schematic diagram of a pressing part 220C according to a third modified example. This pressing part 220C has a height adjustment function. As explained above, the expansion degree of the range of motion of the joint changes depending on the pressure applied to the Pacinian corpuscles. When the pressure is changed to increase stepwise (for example, when the level is changed in the order of weak, medium, and strong), it is known that the range of motion of the joint is expanded most widely when the pressure is set to a strong level up to a certain pressure.

[0135] Figure 40 shows, from top to bottom, photographic images of lateral flexion in the following cases: when using bare hands (holding nothing), when an instrument (grip) for pressing Pacinian corpuscles is held with a weak level of strength as in the first and second embodiments, when the instrument (grip) is held with a medium level of strength, when the instrument (grip) is held with a strong level of strength, and when the instrument (grip) is held with a strength greater than the strong level (strongest).

[0136] According to Figure 40, starting with the bare hand (top image), the subject's left arm reaches a position closer to horizontal in the order of low level, medium level, and strong level. However, when comparing the image of the strongest level (bottom image), where the gripping force is stronger than the strong level, with the strong level just above, the subject's left arm is no different from the strong level. As a result, the position of the arm is slightly higher in the strongest level compared to today's level.

[0137] In this way, when the pressure exceeds the strong level, even if the force applied from the user's fingers (here, the little finger and the ring finger) to the tool 200C is increased and the maximum pressure that the user can exert is applied, the range of motion of the joint does not increase beyond the strong level. Therefore, by changing the amount of protrusion of the pressing part 220C from the main body part 210C for each user and adjusting the height, it is possible to obtain the same level of pressure as when the user exerts maximum force even if the user does not exert maximum force, and thus it is possible to efficiently maximize the effect (the effect of expanding the range of motion of the joint) according to the individual, without requiring excessive force.

[0138] Fig. 39 shows a schematic example of a mechanism for maximizing such an effect. A male screw is formed on the shaft 222C connected to the pressing portion 220C, and the shaft 222C is screwed into a nut 242 fixed to the main body 210C. For example, when a user holds the pressing portion 220C and rotates it forward or backward around the axis, the shaft 222C advances or retreats relative to the main body 210C (moves in the forward or reverse direction of the Z axis), and the amount of protrusion of the pressing portion 220C relative to the main body 210C changes. The shaft 222C and the nut 242 constitute a protrusion amount variable mechanism, and the amount of protrusion of the pressing portion 220C changes due to the protrusion amount variable mechanism.

[0139] By adopting such a mechanism, the height of the pressing part 220C can be adjusted, and a suitable pressure generating function for each user can be realized. Note that the mechanism for adjusting the height of the pressing part 220C is not limited to the one exemplified in Fig. 39, and can be modified in various ways. Also, in Fig. 39, the ring part is omitted from the illustration.

[0140] (Fourth Modification of Pressing Portion 220) 41(a) and (b) are schematic diagrams showing a pressing portion 220D according to a fourth modified example. In the example shown in FIG. 41(a) and (b), the height of the pressing portion 220D is adjustable, similar to the example shown in FIG. 39. However, in the example shown in FIG. 41(a) and (b), the pressing portion 220D is integrally formed with the shaft portion 222D and has the same diameter as the shaft portion 222D. In addition, the shaft portion 222D is formed in a stepped shape and has a flange portion 246 that protrudes in the radial direction.

[0141] A columnar space 248 is formed in the main body 210D. The shaft 222D is inserted into the space 248 so as to be freely displaceable in the axial direction, with the flange 246 positioned within the space 248. A portion having a female thread is formed in a predetermined range on the inner circumferential surface of the space 248, and a disk 250 is screwed into the main body 210D.

[0142] A coil spring 252 is interposed between the disk portion 250 and the flange portion 246 of the shaft portion 222D. A portion of the shaft portion 222D closer to the disk portion 250 than the flange portion 246 is inserted into the coil spring 252. Each end of the coil spring 252 contacts the disk portion 250 and the flange portion 246.

[0143] A groove (driver groove) 254 for a flathead screwdriver is formed in the center of the plate surface of the disk part 250 located opposite to the coil spring 252. A lid 256 is attached to the main body part 210D, and one end (the upper end in Figs. 41(a) and (b)) of the space part 248 is closed in an openable and closable manner by this lid 256. The lid 256 can be removed from the main body part 210D by the user pulling it up by hooking his / her fingers on it, and can be inserted into the space part 248 to close the space part 248 (it is detachable).

[0144] 41(a), when the pressing portion 220D is not subjected to an external force in the axial direction, the shaft portion 222D is in a state of protruding from the main body portion 210D due to the elastic restoring force of the coil spring 252. The positions of the pressing portion 220D and the shaft portion 222D are determined by the engagement of the flange portion 246 with the main body portion 210D.

[0145] Fig. 41(b) shows a state in which pressing portion 220D is subjected to an external force in the axial direction. In this case, coil spring 252 is compressed and elastically deformed via flange portion 246, and shaft portion 222D sinks into space portion 248 depending on the magnitude of the external force. Then, the amount of protrusion of pressing portion 220D from main body portion 210D (height of pressing portion 220D) becomes smaller (height becomes lower) compared to a state in which no external force is applied as shown in Fig. 41(a).

[0146] 41(b), shaft portion 222D is in contact with disk portion 250, and pressing portion 220D and shaft portion 222D are stopped as shaft portion 222D hits disk portion 250. In other words, when shaft portion 222D is retracted, disk portion 250 functions as a stopper that determines the limit of the amount of retraction.

[0147] 41(a) and (b), the height of the pressing portion 220D can be adjusted (the amount of protrusion can be changed) in the same manner as in the example shown in Fig. 39. Furthermore, in the example shown in Fig. 41(a) and (b), it is possible to easily generate a strong level of pressure by elastically changing the amount of protrusion using the elastic restoring force of the coil spring 252.

[0148] 41(a) and (b), a removable lid 256 is provided on the main body 210D, and a driver groove 254 is provided on the disk part 250. The lid 256 is screwed onto the main body 210D and is in contact with the coil spring 252. For these reasons, the elastic restoring force of the coil spring 252 can be changed by removing the lid 256 from the main body 210D and using a flat-head screwdriver to rotate the disk part 250 forward or backward around the axis.

[0149] Therefore, for example, even if the user grips the tool 200D with the same force, the pressing force of the pressing portion 220D can be finely changed depending on the position of the disk portion 250 and the characteristics of the coil spring 252 (such as the spring constant).

[0150] The mechanism for adjusting the height of the pressing part 220D is not limited to the one illustrated in Figures 41(a) and (b) and can be modified in various ways. Also, in Figures 41(a) and (b), the ring part is not shown.

[0151] (Fifth Modification of Pressing Portion 220) 42 is a schematic diagram of a pressing part 220E according to a fourth modified example. In this fourth modified example, the pressing part 220D can be stored in the main body part 210D as shown by the arrow M, and can be pulled out from the main body part 210D. This prevents the pressing part 220E protruding from the main body part 210E from getting caught on the surroundings in a bag (not shown) when the user carries the appliance 200E in the bag.

[0152] 42, the shaft portion 222E is connected to the main body portion 210E via the hinge portion 260 inside the main body portion 210E. Various hinge portions can be adopted as the hinge portion 260. For example, it is conceivable to adopt a hinge portion 260 having a mechanism (such as a ratchet mechanism) that can stop the pressing portion 220E and the shaft portion 222E at least in two stages: a state in which the pressing portion 220E and the shaft portion 222E are protruding from the main body portion 210E, and a state in which the pressing portion 220E and the shaft portion 222E are stored inside the main body portion 210E.

[0153] Also, in order to make it easier to remove the stored pressing portion 220E from the main body portion 210E, it is possible to make at least a part of the pressing portion 220E exposed from a hole or a notch in the main body portion 210E.

[0154] [Modifications Related to the Main Body 210] Next, there will be described various modified examples relating to the pressing portion 220 of the device 200. Note that the same parts as those of the device 200 of the second embodiment are given the same reference numerals, and the description thereof will be omitted as appropriate.

[0155] (First Modification of Main Body 210) Fig. 43 shows a schematic diagram of a main body 210F according to a first modified example. In the example of Fig. 43, the main body 210F is of a swing type that tilts its posture with respect to the shaft 222F (and the pressing portion 220F). The main body 210F can be tilted with the shaft 222F (and the pressing portion 220F) as a reference. The shaft 222F is connected to the main body 210F via a hinge portion 262. Various types of hinge portion 262 can be used.

[0156] For example, it is conceivable to adopt a hinge portion 262 that can stop the main body portion 210F with respect to the shaft portion 222E by frictional force. It is also conceivable to adopt a hinge portion 262 that has a mechanism (such as a ratchet mechanism) that can stop the shaft portion 222E in multiple stages of three or more stages.

[0157] 43, the relative positional relationship between the ring portion 230F and the main body portion 210F can also change due to the swing of the main body portion 210F. In order to achieve this, for example, it is conceivable to configure the ring portion 230F from a material such as a flexible synthetic resin, so that the joint portion (reference numeral omitted) with the main body portion 210F can elastically deform in response to the swing of the main body portion 210F.

[0158] (Second Modification of Main Body 210) Fig. 44 is a schematic diagram of a main body 210G according to a second modified example. In the example of Fig. 44, a little finger stopper 264 capable of locking a little finger protrudes from the main body 210G. This little finger stopper 264 is designed to be locked by the tip (first joint) of the little finger that has passed through the ring portion 230 (omitted in Fig. 44). The little finger stopper 264 may be integrally molded with the main body 210G, or may be formed separately from the main body 210G and attached later.

[0159] [Applying the pressure part to everyday gripping objects] Next, other uses of the pressing parts 20, 220, 220A-220F provided in various instruments 1, 200, 200A-200F will be described. So far, the shapes of the pressing parts 20, 220, 220A-220F have been exemplified as spherical, semispherical, or a multi-stage spherical shape (pressing part 220B) as shown in Fig. 37. All of these pressing parts 20, 220, 220A-220F allow the user to appropriately stimulate the Pacinian points by holding the instruments 1, 200, 200A-200F in their hands.

[0160] In addition, the various instruments 1, 200, 200A to 200F described above are dedicated devices developed for applying pressure to the Pacinian points. The instruments 1, 200, 200A to 200F are intended for users to hold in their hands with the purpose of applying pressure to the Pacinian points in mind.

[0161] By the way, if your body is flexible, you can prevent unexpected breakdowns and injuries in your daily life. For this reason, applying pressure to the Pacinian points in as many situations as possible in your daily life is effective in preventing breakdowns and injuries.

[0162] However, if you always hold the tools 1, 200, 200A-200F in one hand or in each hand, you may experience problems in your daily life, and in some situations, it may even be difficult to live your daily life. Therefore, in order to maintain the flexibility of your body as much as possible while living your daily life, you need to think differently from the idea of ​​holding the dedicated tools 1, 200, 200A-200F, etc., for the purpose of stimulating the Pacinian points, as explained above.

[0163] Therefore, the inventors considered ways to maintain as much physical flexibility as possible while living an everyday life, and came up with the technical idea of ​​providing protrusions such as the aforementioned pressure portions 20, 220, 220A-220F on daily necessities (also called "living goods"), especially daily necessities that are held in the hand (hereinafter referred to as "daily graspable items"), thereby adding pressure portions to various daily necessities (daily graspable items).

[0164] Below, we will show some examples of typical shapes of the pressing part. Furthermore, we will explain the suitable arrangement of the pressing part when forming the pressing part on the daily gripping object, and the effect obtained by forming the pressing part on the daily gripping object. Note that the explanation of the same parts and matters as those explained so far will be omitted as appropriate.

[0165] (Shape and arrangement of pressure parts) First, as an example of the shape of the pressing portion, a hemispherical shape can be exemplified as shown in Fig. 45. In Fig. 45, reference numeral 1410 shows a daily gripping object in a schematic rectangular shape. Therefore, the daily gripping object 1410 in Fig. 45 can be replaced with various daily necessities that are gripped by hand. Examples of the daily gripping object 1410 will be described later.

[0166] 45, when providing the daily gripping object 1410, the pressing part 1420 may be integrally molded with the daily gripping object 1410, or the pressing part 1420 may be formed separately from the daily gripping object 1410 and attached (post-attached) to the daily gripping object 1410 later. Also, the pressing part 1420 may be attached to the gripped part of the daily gripping object 1410 via a structure or mechanism similar to the connection parts (shaft parts) 22, 222, 222C-222F of the appliances 1, 200, 200A-200F.

[0167] 45, two pressing parts 1420 are arranged at a predetermined interval on the gripped part of the daily grip object 1410. Therefore, the daily grip object 1410 can be used for a purpose to be gripped by a user with both hands.

[0168] In the case of the hand, the Pacinian corpuscles are present near the center of the palm on the little finger side (A in the figure) and at the tip of the middle finger (B in the figure) as shown with reference to the above-mentioned Figure 30. Therefore, the distance between the two pressing parts 1420 (here, the center distance) can be set to match the distance between the areas where the centers of both palms (A in the figure) are located when the daily gripping object 1410 is used in a normal manner.

[0169] The distance between the hands when the daily gripping object 1410 is used in a normal manner can be determined, for example, as follows. First, data on the distance between the hands when the daily gripping object 1410 is used is collected for each of a plurality of people. The subjects from whom this sample is collected are those who match the age and sex of the users who will be the consumers of the daily gripping object 1410. Then, statistical processing (such as obtaining an average value) is performed on the data on the distance between the hands, and the distance between the two pressing parts 1420 (here, the center distance) is determined according to the obtained results.

[0170] The distance between the two pressing parts 1420 (here, the center distance) may be the distance between the tips of the middle fingers of both the left and right hands (B in FIG. 30, which is incorporated herein). Alternatively, it may be set to match the distance between the center of the palm of one hand (A in FIG. 30) and the tip of the middle finger of the other hand (B in FIG. 30). In these cases, too, it is possible to set the distance between the two pressing parts 1420 (here, the center distance) assuming that the daily gripping object 1410 is used in a normal manner.

[0171] As another example of the shape of the pressing portion, a multi-stage hemispherical shape can be exemplified as shown in Fig. 46. Each pressing portion 1470 in the example of Fig. 46 can have a shape similar to that of the pressing portion 220B shown in Fig. 37. The pressure is applied to the Pacinian point mainly by the first contact portion 1471B1 at the tip, which has a smaller diameter than the other portions.

[0172] The interval (here, center interval) of this type of pressing portion 1470 can be set in the same way as the pressing portion 1420 in the example of Fig. 45. Here, what is indicated by reference numeral 1460 in Fig. 46 is a daily gripping object that is diagrammatically represented by a rectangular figure. Also, what is indicated by reference numeral 1471B is a contact portion of the pressing portion 1470, and what is indicated by reference numeral 1471B2 is a second contact portion of the pressing portion 1470.

[0173] The number of pressing parts 1420, 1470 described above is not limited to two. The number of pressing parts 1420, 1470 may be one, or three or more. However, assuming a situation in which one user uses daily gripping objects 1410, 1460, it is considered desirable for the number of pressing parts 1420, 1470 to be two or one.

[0174] In addition, the pressing portion is not limited to the shape illustrated in Fig. 45 and Fig. 46, and may be, for example, the other types of pressing portions 220A, 220C to 220F described above, or other types, as long as the use of the daily gripping object is not hindered. In addition, the pressing portion is not limited to the shape illustrated in Fig. 45 and Fig. 46, and may be, for example, a pressing portion having a height adjustment function as shown with reference to Fig. 39 and Fig. 41.

[0175] By replacing main body portions 210C, 210D and pressing portions 220C, 220D shown in Figures 39 and 41 with daily graspable items 1410, 1460 and pressing portions 1420, 1470, it is possible to apply the examples of Figures 39 and 41 to the examples of Figures 45 and 46.

[0176] Alternatively, the pressing part may be retractable, as shown in FIG. 42. In this case, it is possible to store the pressing part in a daily gripping object in which the pressing part is provided. When considering the example of FIG. 42, it is possible to replace the main body 210E in FIG. 42 with a daily holding object.

[0177] Furthermore, the pressing portion may be relatively inclined as shown in FIG. 43. In this case, it may be retractable. When considering the example of FIG. 43, the main body 210F in FIG. 43 can be replaced with a daily gripping object.

[0178] (Examples of everyday items to be held) Next, the daily gripping objects 1410 and 1460 will be described with examples. First, as explained above, by pressing the Pacinian corpuscles in the palm of the hand with an appropriate force, muscle relaxation occurs throughout the body. Therefore, by simply pressing the Pacinian corpuscles, the stiffness of the entire body can be relieved and the person can relax without moving the body.

[0179] In addition, when you move your body, the range of motion of your joints increases due to muscle relaxation, and the stretching effect on your stiff muscles is further enhanced. This allows you to move your body more agilely and with greater freedom. In order to achieve this synergistic effect on a daily basis without having to set aside special time for exercise, the following example tool is equipped with a pressure part for pressing the Pacinian corpuscles.

[0180] Daily gripping objects can be classified from various viewpoints, but here, daily gripping objects are classified into four categories: exercise equipment (sports equipment), rehabilitation equipment, daily living equipment, and elderly support equipment. Note that the classification of daily gripping objects is not limited to the classification described here, and various classifications are possible. Also, there may be cases where a daily gripping object included in one classification is also included in another classification (cross-classification).

[0181] (1) Exercise equipment Exercise equipment can be exemplified by equipment for improving motor function, and examples of such equipment include muscle-stretching training equipment (e.g., stretching, yoga, muscle training), athletics equipment (e.g., relay races using batons, javelin throwing), and ball game equipment (e.g., baseball, golf), etc. For exercise equipment that is grasped with the hands and used for exercise, the pressure part is placed within a range that can come into contact with the Pacinian point when the hands are positioned as they would be in normal use.

[0182] A specific example of the exercise equipment is a golf grip, which is gripped by the user. FIG. 47 shows a semicircular figure that shows that a pressing part 1512 is provided to protrude from the outer periphery of a golf grip 1510. The shape and configuration of the pressing part 1512 may be the pressing parts 1420 and 1470 shown in FIG. 45 and FIG. 46, or the shapes and configurations of the other pressing parts 220A, 220C to 220F described above. This point is also true for various daily gripping objects exemplified below.

[0183] For example, suppose a person whose body is relatively stiff (relatively inflexible) and whose joints such as arms, elbows, and shoulders cannot bend (move) to the correct, ideal form when playing golf or practicing golf uses golf club 1514 equipped with golf grip 1510 having pressure portion 1512.

[0184] In this case, the user of the golf club 1514 grips the golf grip 1510 and uses the golf club 1514 with the pressing part 1512 touching the Pacinian point of the palm. When the pressing part 1512 touches the Pacinian point, muscle relaxation occurs, which increases the range of motion of the joints and allows the body to bend naturally. As a result, it is expected that the user's form will become closer to the correct form. Note that, although the golf grip 1510 is described here as an everyday gripping object, the golf club 1514 to which the golf grip 1510 is attached can also be used as an everyday gripping object.

[0185] It is also possible to place pressure parts on the handles and dumbbells of exercise machines such as fitness bikes (also known as aero bikes (registered trademark)) and shoulder presses at positions where they are gripped or pressed by the hands. Fig. 48 shows that two pressure parts 1522 are provided to protrude from a handle 1524 of a fitness bike 1520. Fig. 49 shows that a shoulder press 1530 has a pressure part 1532 provided to protrude from it.

[0186] (2) Rehabilitation equipment Examples of rehabilitation tools include handrails for assisting people to stand up, nursing beds, nursing tableware, rehabilitation walking sticks, etc. For tools that are used by holding them with the hands, the pressing part is placed within the area where the hand can come into contact with the Pacinian point of the hand when it is in the position where it is normally used.

[0187] Fig. 50 shows that a pressing part 1562 is provided to protrude from the outer periphery of a standing-up handrail 1560. Fig. 51 shows that a pressing part 1552 is provided to protrude from a handrail 1574 of a nursing bed 1570. Fig. 52 shows that a pressing part 1582 is provided to protrude from a gripping part 1584 of a spoon 1580 of a nursing tableware. Fig. 53 shows that a pressing part 1592 is provided to protrude from a gripping part 1594 of a rehabilitation cane 1590.

[0188] In cases such as hospitalization for illness treatment, patients may be bedridden and not move their muscles much for long periods of time. In such cases, the muscles become stiff, and even after the illness is cured, the muscles remain stiff, and the range of motion of the joints becomes narrower than when healthy. However, by providing a pressure part on the rehabilitation equipment used during hospitalization, the pressure part hits the Pacinian points during rehabilitation exercises, causing muscle relaxation and expanding the range of motion of the joints naturally. This makes it difficult to feel pain, making it easier to continue rehabilitation. This is expected to shorten the physical recovery period (rehabilitation period).

[0189] (3) Daily utensils There are various kinds of daily necessities, but it is considered that those that are used for a relatively long time each time (for example, those that are used continuously for more than a few minutes) are particularly suitable. Specific examples include smartphones, smartphone cases, kitchen knives, frying pans, electric toothbrushes, motorcycles, bicycles, automobiles, automobile handlebars, hair dryers, water bottles (for walking, for example), etc. For such tools that are used by holding them in the hand, the pressing part is placed within an area that can come into contact with the Pacinian point of the hand when the hand is in the position when used normally.

[0190] Fig. 54 shows a schematic diagram of a pressing portion 1622 provided so as to protrude from the outside of a smartphone 1620. Here, it is also possible to provide the pressing portion 1622 on a case (smartphone case) attached to the smartphone 1620. Fig. 55 shows a schematic diagram of a pressing portion 1632 provided so as to protrude from a handle 1634 of a knife 1630. Fig. 56 shows a schematic diagram of a pressing portion 1642 provided so as to protrude from a handle 1624 of a frying pan 1640.

[0191] FIG. 57 shows a schematic diagram of a pressing portion 1652 provided to protrude from a main body portion 1654 of an electric toothbrush 1650. The toothbrush may be a non-electric toothbrush (not shown) as well as the electric toothbrush 1650. FIG. 58 shows a schematic diagram of two pressing portions 1662 provided to protrude from a handlebar 1664 of a motorcycle 1660. FIG. 59 shows a schematic diagram of two pressing portions 1672 provided to protrude from a handlebar 1674 of a bicycle 1670. FIG. 60 shows a schematic diagram of two pressing portions 1682 provided to protrude from a handlebar 1680 of an automobile. FIG. 61 shows a schematic diagram of a pressing portion 1692 provided to protrude from a handlebar 1694 of a hair dryer 1690.

[0192] If a pressure point is provided on a lifestyle tool, the pressure point will come into contact with the Pacinian point on the palm of the hand as the person goes about their daily life, causing muscle relaxation and allowing the person to relax. In addition, when the person performs an action using the lifestyle tool in a state of muscle relaxation, the range of motion of the joints will increase, allowing the person to move more lightly. As a result, it is expected that the amount of physical activity will increase when performing habitual actions.

[0193] (4) Assistive devices for the elderly Examples of elderly support equipment include silver carts (walkers), toilet seats with handles, shower benches, bath grips, walking sticks, etc. For equipment that is used by holding it with the hand, the pressure part is placed within the area where it can come into contact with the Pacinian point of the hand when the hand is in the position when it is normally used.

[0194] FIG. 62 shows a model of a handle 1714 of a silver cart 1710 having two pressing parts 1712 protruding therefrom.

[0195] As the elderly age, their muscles become stiffer, and the range of motion of their joints becomes narrower. By providing a pressure section on the gripped part where the user holds onto products such as silver carts, toilet seats with handles, shower benches, bath grips, and walking sticks, the muscles of the entire body become relaxed, making it easier for the elderly to walk and perform other movements.

[0196] (Installation of the pressure part) In any of the daily gripping objects, the pressing part is attached to the part that is held by the hand (the gripped part) or the part that the hand is pressed against (the gripped part that is the pressing part). The pressing part may be attached directly to the attachment object when the attachment object, such as each daily gripping object or a part of each daily gripping object, is produced, manufactured, or assembled. Alternatively, for example, as shown typically in the example of a silver cart 1710 in FIG. 62, a pressing part 1712 may be provided on an attachment part (attachment part) 1716, and the pressing part 1712 may be attached (post-attached) to a handle 1714 of the silver cart 1710 via the attachment part 1716, as shown by the arrow N.

[0197] In the example shown in FIG. 62, a cylindrical cover 1718 is used as the attachment part. The cover 1718 has a shape cut along the longitudinal direction of a tube, and has a C-shaped cross section as shown on the right side of FIG. 62. A pressing part 1712 is provided so as to protrude from the outer periphery of the cover 1718. The cover 1718 is formed of a material and has a shape that allows elastic deformation. Metal, synthetic resin (plastic), etc. can be used as the material of the cover 1718. It is also possible to configure the cover 1718 by combining a metal part and a synthetic resin (plastic) part.

[0198] When the pressing portion 1712 is to be retrofitted to the silver cart 1710, the cover 1718 is pressed against the handle 1714 with the slit in contact with it. Then, while elastically deforming the cover 1718, the slit of the cover 1718 is pushed open, and the cover is placed over the handle 1714 so that the left and right sides are evenly balanced.

[0199] Cover 1718 pinches handle 1714 while exerting an elastic restoring force, and is fixed to handle 1714. Cover 1718 is fixed to handle 1714 by the elastic force of cover 1718, and mounting of pressing portion 1712 to silver cart 1710 is completed.

[0200] It is possible to fix cover 1718 by frictional force so that it does not rotate around handle 1714. Also, it is possible to make the cross-sectional shapes of handle 1714 and cover 1718 non-circular (for example, non-circular shapes such as oval shapes) and to stop rotation by engaging cover 1718 with handle 1714. Also, the method of attaching cover 1718 to handle 1714 is not limited to elastic force, and cover 1718 may be fixed to handle 1714 using a fastener such as a screw.

[0201] In addition to the illustrated everyday graspable items, other examples of everyday graspable items include shiatsu and massage tools and equipment, mice, game controllers, furniture (such as chair armrests), and public transportation poles and hanging rings. Of these, shiatsu and massage tools and equipment are classified as rehabilitation tools and daily living tools. The pressure part is placed on the gripped part of these shiatsu and massage tools and equipment (such as the handle or grip part, or the armrest for seated items).

[0202] Moreover, a mouse is an input device that is connected to a PC (personal computer) and has a gripped part that is held and multiple input switch parts. A game controller is an input device that has multiple game operation buttons on a gripped part that is held with one or both hands. For these, it is possible to place a pressing part on the gripped part at a part that is expected to face the Pacinian point when held in a normal manner. Similarly, for furniture (such as the armrests of a chair), it is possible to place a pressing part on the part that is held.

[0203] Public transport poles and hanging rings are used by passengers on trains and buses to hold on to their bodies. The position of the pole to be held varies depending on the physique and age, but it is possible to set the part to be held at the standard height for the physique and age selected as a standard, and to place the pressure part at the part to be held that is expected to face the Pacinian point. For hanging rings, it is possible to place the pressure part at the part to be held that is expected to face the Pacinian point when held in the normal manner.

[0204] Although various embodiments and modifications of the device and the pressing portion have been described above, the present invention is not limited to these, and many modifications are possible within the scope of the technical idea of ​​the present invention. Furthermore, it is also possible to appropriately combine the various aspects described so far, unless there is any particular problem.

[0205] In addition, each embodiment is merely an example of a specific embodiment of the present invention, and the technical scope of the present invention should not be interpreted as being limited by this. In other words, the present invention can be implemented in various forms without departing from the gist or main features of the present invention. For example, each configuration of the embodiment may be implemented in combination with each other. [Explanation of symbols]
