Description

  TECHNICAL FIELD The present invention relates to a finger movement assisting tool for easily and effectively moving a finger and a holding tool for learning how to properly hold a writing tool.

  Cerebral physiology scientists say that "the hand is the second brain" and that "humanity has evolved to use the hand by bipedal walking", the movement of the hand (finger) is the brain There is a great effect on activation (increase in blood flow in the brain). For example, even simple finger movements such as bending the index finger increase the blood flow in the brain by about 10 percent compared to when you are still doing nothing, and you can just eat with chopsticks It is said that roughly half of the cerebral cortex works.

  Here, when writing is performed with a writing instrument such as a pencil or a ballpoint pen, it is said that 15 joints including 15 joints of 5 fingers and 16 joints including a wrist joint move. Whether or not these 16 joints can be moved freely is dependent on the brain that controls the nerves and muscles that control the movement of all joints. Is activated, and blood flow in the brain is remarkably increased. In other words, writing with a writing instrument correctly activates the brain, and is particularly effective in promoting the growth of infants and children and preventing and improving the aging of the elderly.

  The correct way to hold a writing instrument is as follows. The key points regarding the correct way of holding a writing instrument are: (1) the position of holding the writing instrument (the gripping position of the writing instrument), (2) the shape of the hand and the amount of force that can be achieved when holding the writing instrument, and (3) the writing instrument. This is the angle between the pencil and the paper surface when it is held (the gripping angle of the writing instrument). Specifically, at the point (1) “position where the writing tool is held (holding position of the writing tool)”, “(a) the tip of the index finger comes slightly ahead of the tip of the thumb. (B) the tip of the index finger. (C) The middle finger, ring finger, and little finger are lightly bent inward, and the inside of the hand is in the state of holding an egg (d) The tip of the little finger is lightly attached to the paper surface, It is appropriate that “the three joints are separated from the paper surface”. In point (2), “How to put hand and shape when holding a writing instrument”, “(a) Do not put too much force on the wrist and fingers. (B) Put too much force on the index finger and thumb. It is appropriate not to have these joints be rounded. In point (3) “An angle formed by a pencil and a paper surface when holding a writing device (holding angle of the writing device)”, an inclination angle formed by “(a) the pencil and the paper surface is 50 ° to 60 °. (B) The axis of the pencil touches slightly before the joint of the fingertip of the middle finger (c) The axis is placed in the middle of the second and third joints of the index finger (d) When writing the pencil tip in the correct posture It is considered appropriate to “make it a position that is always visible”.

In this regard, Non-Patent Document 1 discloses an example of a conventional writing instrument and chopstick holding practice tool for solving the above-described problems. As shown in FIG. 1 of Non-Patent Document 1, this practice tool has a substantially E-shaped cross section, and the upper wall portion and the lower wall portion are formed so as to be opposed to each other. It has a shape that is curved so that the distance from the upper wall portion increases as it goes to each end portion. By using this practice tool, it is easy to learn how to hold a correct writing instrument and chopsticks that capture the points (1) to (3) above. Note that the writing instrument and the chopstick holding practice tool described in Non-Patent Document 1 were devised by the present inventors.

  Certainly, according to the conventional practice tool, the finger can be moved effectively to some extent during writing. However, it could not be used as a health device that can move fingers easily and effectively without writing.

  In addition, as a practice tool that can move fingers effectively when writing, “middle finger, ring finger, little finger should be bent slightly inward and the inside of the hand should be in a state of holding an egg (point 1 (c))” It cannot be said that it is sufficiently satisfactory in that it is learned that “do not put too much force on the index finger and thumb and make the joints round (point 2 (b))”. In other words, with the above exercise tool, the inner space of the hand is gradually reduced as writing continues, and the thumb, index finger, and middle finger joints stretch, and the fingers (joints) that should move when held correctly do not move. It is.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a finger motion assisting tool that can easily and effectively perform finger motion effective for brain activation.

  The finger movement assisting tool of the present invention includes an upper wall portion and a lower wall portion that face each other at intervals, and a clamping wall portion that connects the upper and lower wall portions so as to divide the space between the upper and lower wall portions into two. An upper wall portion side of the lower wall portion, and a grasping portion provided on the lower side of the lower wall portion, and two spaces (hereinafter referred to as the first finger) formed by the upper and lower wall portions and the sandwiching wall portion. A finger can be inserted into each of the insertion part and the second finger insertion part, and a plurality of fingers including the two inserted fingers can contact the grasping part.

  Hereinafter, a direction from the lower wall portion to the upper wall portion is defined as an upward direction, and a direction from the upper wall portion to the lower wall portion is defined as a downward direction. The upper wall portion can be divided into two regions by the intersection of the upper wall portion and the sandwiching wall portion, one of which is the first upper wall portion and the other is the second upper wall portion. Similarly, the lower wall portion can be divided into two regions by the intersection of the lower wall portion and the sandwiching wall portion, one of which is the first lower wall portion and the other is the second lower wall portion.

  The finger movement assisting tool of the present invention correctly holds a writing instrument and chopsticks during writing and meals as a health instrument (pure health instrument) that allows the user to perform a finger motion without writing. It can also be used as a corrector and health appliance that can move the

  First, the case where it uses as a pure health appliance is demonstrated.

  The user inserts the adjacent first and second fingers (for example, the index finger and the middle finger) into the first finger insertion portion and the second finger insertion portion of the finger movement assisting tool, and the first joint from the base of the first finger. So that most of the distance from the base of the second finger to the first joint is accommodated in the second finger insertion part. At this time, the holding wall portion is lightly sandwiched between the base portions of the first finger and the second finger, the first upper wall portion is positioned on the first finger, and the first lower wall portion is positioned below the first finger, and The second upper wall portion is positioned on the second finger and the second lower wall portion is positioned below the second upper wall portion (par state).

  In this state, the user bends each finger, and the part from the first joint to the fingertip of the first finger and the second finger and the other finger are brought into contact with the surface of the grasping unit (the fingers are placed on the grasping unit). ) Gradually grab the grasping part, which is an elastic body, with each finger (goo state). If it is grasped until the grasping part becomes small to some extent, each finger is opened and the par state is established. Moreover, if the thumb, little finger, and ring finger are closed when the finger is opened, it can be in a choke state.

  By appropriately mixing and repeating the above operations (par, goo, choki), it is possible to effectively move the five fingers and to activate the brain.

  Here, if this finger movement assisting tool is worn, as described above, the holding wall portion is sandwiched between the index finger and the middle finger, and the first upper wall portion is positioned on one of the fingers and the first lower wall portion is below it. And the second upper wall portion is positioned on the other finger and the second lower wall portion is positioned below the second upper wall portion. Therefore, you can bend and stretch each finger (goo, par or choki), and even if you repeat it vigorously or turn your hand in any direction (turn over), this finger movement aid will come off your finger (hand) There is nothing. In addition, the attachment is very easy because only two fingers are inserted into the first and second finger insertion portions.

  Thus, according to the finger movement assisting tool, finger movement effective for brain activation can be easily and effectively performed.

  When used as a corrector and health appliance, it is used as follows.

  For example, in the case of holding a pencil, the user bends each finger and sandwiches a predetermined point below the pencil with the thumb, forefinger and middle finger, and at the end of the first lower wall (the end in the finger insertion direction) Place (hang) a predetermined point. At this time, it is felt that the grasping part is lightly grasped by a part of the thumb, ring finger, little finger and palm. As a result, an appropriate space can be forced inside the hand, and the index finger and thumb joints are naturally rounded. Therefore, the middle finger, ring finger, little finger should be bent slightly inward and the inside of the hand should be in the state of grasping the egg (point 1 (c)) or "do not put too much force on the index finger or thumb. Therefore, it is possible to acquire effectively (forcefully speaking) that the joints have roundness (point 2 (b)). All 16 joints can move effectively and increase brain activation.

  In the finger motion assisting tool of the present invention, it is preferable that the grasping portion is a sphere or an elliptic sphere. By configuring the grasping portion with a curved surface in this way, the user can comfortably perform the above-described operations (goo, par, choki) or writing without feeling painful or uncomfortable.

  In the finger motion assisting tool of the present invention, it is preferable that the grasping portion is made of an elastic member (for example, rubber or sponge material). By configuring the grasping portion with an elastic body, the user can perform the goo motion more firmly, and the brain activation effect can be enhanced. In addition, the pain and discomfort felt when the grasping portion is made of a hard (non-elastic) material can be eliminated, and the above operations (goo, par, choki) or writing can be performed comfortably.

  In the finger motion assisting tool of the present invention, it is preferable that the grasping part is removable from the lower wall part. For example, a concave portion is formed in the grasping portion and a convex portion is formed on the lower wall portion, and the grasping portion is made detachable by inserting and removing the convex portion of the lower wall portion into the concave portion of the grasping portion. In this way, it is possible to respond to each user's physique (size of hand and fingers, grip strength) and preferences just by exchanging the grasping part (detaching from the lower wall part), and in addition, the finger movement itself can be varied. It is very convenient. It should be noted that it is preferable to prepare various kinds of replacement grasping parts (grasping bodies) having different sizes, elastic forces, materials, and the like.

  In the finger motion assisting tool of the present invention, it is preferable that the upper wall portion has a shape warped in a direction away from the lower wall portion.

That is, it becomes possible to deal with more users.

  In the finger movement assistance tool of the present invention, it is preferable that the lower wall portion is formed of an elastic material. The lower wall portion may be formed of a hard material such as plastic, but a soft material such as rubber is used because it is a portion that contacts the finger (from the root to the first joint) more strongly. Thereby, this finger movement aid can be used comfortably, without feeling a pain or discomfort.

  In the finger motion assisting device of the present invention, the lower wall portion is divided into the first and second lower wall portions at the intersection with the sandwiching wall portion, and the upper wall portion and the first lower wall portion When the index finger is inserted into the space formed by the wall part and the sandwiching wall part, it is preferable that the first lower wall part is formed with a region where the index finger contacts and a surplus region where the index finger does not contact.

  As described above, when this finger movement assisting tool is used as an orthodontic / health appliance, the writing instrument is brought into contact with the end of the first lower wall portion. At this time, the end of the surplus area (in the finger insertion direction) If a writing instrument or the like is brought into contact with the end), the writing instrument becomes stable and easy to write.

  Moreover, in the finger movement assistance tool of this invention, the fingertip of the index finger which contacted the 1st lower wall part shall be in contact with the grasping part, and the grasping part has an end in the direction along the finger insertion direction in the surplus region. It is preferable that the groove part which goes to the contact part of the said fingertip in a grasping part from the part is provided. According to the above configuration, the writing instrument is more stable and more easily written by biting into the groove portion of the grasping portion while contacting the end portion of the surplus region.

[Embodiment 1]
In the present embodiment, a finger motion assisting tool that is mainly used as a health device (that can move a finger effectively without writing) will be described.

  Fig.1 (a) is a perspective view of the finger movement assistance tool which concerns on this Embodiment, (b) is the sectional drawing. The finger movement assisting tool 1 includes an upper wall portion 12 and a lower wall portion 22 that face each other, a sandwiching wall portion 30, and a grasping portion 23.

  The upper wall portion 12 and the lower wall portion 22 have a configuration in which two rectangular plate-like members are opposed to each other and gently bent in opposite directions. The sandwiching wall portion 30 is also a rectangular plate-like member, and the upper and lower wall portions 12 and 22 are connected at a predetermined interval. Here, the intersecting portion of the upper and lower wall portions 12 and 22 and the sandwiching wall portion 30 crosses the central portion of the upper and lower wall portions 12 and 22, and the normal of the upper wall portion 12 and the method of the lower wall portion 22 at the intersecting portion. The lines are almost orthogonal. Thus, the space sandwiched between the upper wall portion 12 and the lower wall portion 22 is divided into two concave portions by the sandwiching wall portion 30, and a finger is inserted into each of the two concave portions.

  In the following description, the direction from the lower wall portion 22 toward the upper wall portion 12 is the upward direction, the direction from the upper wall portion 12 toward the lower wall portion 22 is the downward direction, and the length of the plate-like members constituting the upper and lower walls 12, 22 The direction is defined as the left-right direction. For example, the upper wall portion 12 has a shape that warps upward (convex downward).

  The upper wall portion 12 can be divided into two regions by the intersection of the upper wall portion 12 and the sandwiching wall portion 30, one of which is the first upper wall portion 12a and the other is the second upper wall portion 12b. To do. Similarly, the lower wall portion 22 can be divided into two regions by the intersection of the lower wall portion 22 and the sandwiching wall portion 30, one of which is the first lower wall portion 22a and the other is the second lower wall portion 22b. To do. Further, with respect to the first upper wall portion 12a or the second upper wall portion 12b, the length in the left-right direction (the length along the circumference) is referred to as the width of the first upper wall portion 12a or the second upper wall portion 12b. . Similarly, regarding the first lower wall portion 22a or the second lower wall portion 22b, the length in the left-right direction (the length along the circumference) is set to the width of the first lower wall portion 22a or the second lower wall portion 22b. Called. Further, the length in the vertical direction of the sandwiching wall portion 30 is referred to as the distance between the upper and lower wall portions. The concave space surrounded by the first upper wall portion 12a, the sandwiching wall portion 30, and the first lower wall portion 22a is defined as the first finger insertion portion 25a, the second upper wall portion 12b, the sandwiching wall portion 30, and the second lower wall. A concave space surrounded by the portion 22b is defined as a second finger insertion portion 25b.

  A spherical grasping portion 23 is fixed to the lower side of the lower wall portion 22, and a part of the surface thereof is flush with the lower surface of the lower wall portion 22. The size of the grasping portion 23 is preferably a size that allows the whole to be surrounded by five fingers with a margin to a large tennis ball. The material is preferably an elastic material such as rubber, urethane, foam (sponge), silicon, or soft resin. Moreover, you may be the structure which made the surface the product made from rubber | gum or urethane and filled gas and the liquid in it.

  The width of the first upper wall portion 12a and the second upper wall portion 12a is somewhat shorter than the width of the index finger, and the width of the first lower wall portion 22a and the second lower wall portion 22b is somewhat longer than the width of the index finger. . The length of the sandwiching wall portion 30 (upper and lower wall portions 12 and 22) in the finger insertion direction is such that the distance from the base of the index finger or middle finger to the first joint is sufficient. The distance between the upper and lower wall portions (the length in the vertical direction of the clamping wall portion 30) is set to be slightly larger than the thickness from the base of the index finger or middle finger to the first joint. In addition, as a material of the upper wall part 12, the lower wall part 22, or the clamping wall part 30, a plastic resin or wood can be mentioned, for example.

  Below, with reference to FIG. 2 (a)-(d) and FIG. 3 (a)-(c), the usage pattern of this finger movement assistance tool 1 is demonstrated.

  The user inserts adjacent fingers (for example, the index finger and the middle finger) into the first finger insertion part 25a and the second finger insertion part 25b (see FIGS. 1A and 1B) of the finger movement assisting tool 1, For example, most of the index finger base to the first joint fits in the first finger insertion portion 25a, and most of the middle finger base to the first joint fits in the second finger insertion portion 25b (FIG. 2A). reference). At this time, the holding wall part 30 is lightly sandwiched between the index finger and the base part of the middle finger, the first upper wall part 12a is located above the index finger, the first lower wall part 22a is located below it, and the upper part of the middle finger 2nd upper wall part 12b is located, and it becomes the appearance that the 2nd lower wall part 22b is located under it (par state, refer to Drawing 2 (b)). In addition, since the upper wall portion 12 has a shape that warps upward, even if the user has a large finger, the user does not feel cramped. Each finger can be inserted into the second finger insertion portions 25a and 25b.

  In this state, the user bends each finger and brings the index finger and the middle finger from the first joint to the fingertip and the other three fingers (thumb, ring finger, little finger) in contact with the surface of the grasping unit 23 (holding) After holding each finger on the part 23), gradually grasp the grasping part 23, which is an elastic body, with each finger (goo state, see FIG. 2C). If the grasping part 23 is grasped until it becomes small to some extent, this time, each finger is opened and the state shown in FIG. Further, if the thumb, little finger, and ring finger are closed when the finger is opened, a choke state (FIG. 2D) can be achieved.

  By appropriately mixing and repeating the states (motions) of par, goo, and choki, it is possible to effectively move the five fingers and to activate the brain.

  Here, if the finger movement assisting tool 1 is worn, as described above, the holding wall portion 30 is sandwiched between the index finger and the middle finger, and the first upper wall portion 12a is positioned on one of the fingers and the first lower wall is located below the first upper wall portion 12a. The lower wall portion 22a is positioned, and the second upper wall portion 12b is positioned on the other finger, and the second lower wall portion 22b is positioned below the second upper wall portion 12b.

  Therefore, once this finger movement assisting tool 1 is put on, each finger is bent and stretched (goo and par or choki), and even if it is repeated vigorously, the hand is turned in any direction (turned over), This finger movement aid 1 does not come off the finger (hand). In addition, the attachment is very easy because only two fingers are inserted into the first and second finger insertion portions 25a and 25b. That is, according to the finger movement assisting tool 1, finger movement effective for brain activation can be performed easily and effectively.

  If the above operation is repeated several times, it is more effective to change the insertion finger of the finger operation aid 1. For example, as shown in FIG. 3A, the ring finger and the little finger are inserted into the first finger insertion part 25a and the second finger insertion part 25b, and the above operations (goo, choki, par) are similarly performed. In this case, since the movement of each finger is completely different from the case where the finger operation assisting tool 1 is inserted into the index finger and the middle finger, further activation of the brain can be achieved. It is also possible to put the finger movement assisting tool 1 on each of the left and right hands and repeat each of the above operations. At this time, while moving the left and right arms (for example, swinging to draw the character ∞) More effective.

  Further, as shown in FIGS. 3B and 3C, it is also possible to use two finger movement assisting tools 1 simultaneously attached to one hand. For example, insert one index finger and middle finger into one finger movement assisting tool 1 (with a smaller grasping part 23), and insert the other finger movement assistance tool 1 (with smaller grasping part 23) into a ring finger and little finger. Perform each of the above operations (goo, choki, par). In this case, the movement of each finger is more complicated than the case where only one finger movement assisting tool 1 is worn, so that the brain can be further activated.

  In addition, when using the finger movement assistance tool 1 as a writing tool holding | maintenance correction tool, it uses as follows.

  For example, in the case of holding a pencil, after the state shown in FIG. 2A, the user bends each finger to pinch a predetermined point below the pencil with the thumb, forefinger and middle finger, and at the end of the first lower wall portion 22a (finger Place a predetermined point on the upper part of the writing instrument (end) in the insertion direction. At this time, it is felt that the grasping part is lightly grasped by a part of the thumb, ring finger, little finger and palm. As a result, an appropriate space can be forced inside the hand, and the index finger and thumb joints are naturally rounded. Therefore, the point 1 (c), the point 2 (b), and the like described in the assignment can be acquired very effectively (in other words, forcibly). Furthermore, if written in this correct way, all the 16 joints described above can effectively move and increase the activation of the brain.

  Below, with reference to FIG. 4 (a) (b)-FIG. 6 (a) (b), the deformation | transformation structural example of the finger movement assistance tool concerning this Embodiment is demonstrated.

  In the present embodiment, as shown in FIG. 5C, a large number of protrusions (stimulation surface protrusions) 55 may be provided on the surface of the grasping portion 23. In this way, when the user grasps the grasping unit 23, stimulation is given to each finger and palm, and the brain activation effect is further enhanced. Moreover, you may provide the mineral etc. (not shown) which have a good effect on a magnetic body or a human being in the grasping | reading part 23. FIG. In this way, an additional effect such as further improving blood flow of the hand by a magnetic field generated around the grasping unit 23 can be obtained.

  In the present embodiment, as shown in FIG. 4A, the grasping portion 23 can be removed without being fixed to the lower wall portion 22. In this case, for example, a replacement convex portion 26 that protrudes downward is provided at the center portion of the lower surface of the lower wall portion 22 (in the vicinity of the center of gravity of the plate-like member constituting the lower wall portion 22). Correspondingly, the grasping part 23 is provided with a grasping part replacement recess 27. If various types of grasping unit 23 having different sizes, elastic forces, or materials are prepared, each user's physique (hand or finger) can be changed by simply replacing the grasping unit 23 (detaching from the lower wall unit 22). (Size, grip strength) and suits your preference. In addition, the finger movement itself (and its effect) can be varied.

  As an example of the structure of the grasping portion replacement convex portion 26, as shown in FIG. 4A, for example, a neck portion 26a and a spherical head portion 26b having a collar portion 26p are provided. On the other hand, the grasping portion replacement recess 27 is provided with an opening hole 27a corresponding to the neck portion 26a and a spherical space portion 27b corresponding to the head portion 26b. In this way, when the grasping portion replacement convex portion 26 is inserted into the grasping portion replacement concave portion 27, the head portion 26b is fitted into the space portion 27b, and force (for example, downward centrifugal force or the like) is applied to the grasping portion 23 during use. ), The entrance portion of the space portion 27b is caught in the flange portion 26p. Thereby, the problem that the grasping part 23 comes out of the lower wall part 22 while using the finger movement assisting tool 1 can be avoided.

  Moreover, in this finger movement assistance tool 1, it can also comprise so that the distance between an up-and-down wall part can be adjusted. In this case, as shown in FIG. 4 (b), the sandwiching wall portion 30 is separated, and is composed of an upper sandwiching wall portion 30a and a lower sandwiching wall portion 30b having a larger thickness than the upper sandwiching wall portion 30a. The holding wall part 30a is integrated and the lower wall part 22 and the lower holding wall part 30b are integrated. Then, a plurality of convex portions 31 are provided on both side surfaces of the upper holding wall portion 30a at predetermined intervals in the vertical direction. The convex portion 31 may be a hook-like projection parallel to the finger insertion direction. On the other hand, the lower clamping wall 30b is provided with a groove 32 that is dug down from the upper surface (having a depth in the vertical direction) and extends along the finger insertion direction. The width (width in the left-right direction) of the groove 32 corresponds to the thickness of the upper holding wall portion 30a. Furthermore, stoppers 41a and 41b protruding in the left-right direction (groove center) are formed on the two left and right wall surfaces of the groove 32. In addition, if the convex part 31 is a hook-shaped protrusion as mentioned above, stopper 41a * 41b will also be a hook shape (it extends along a finger insertion direction).

  In this way, when the upper clamping wall 30a is inserted into the groove 32 formed in the lower clamping wall 30b, the convex part 31 of the upper clamping wall 30a and the stoppers 41a and 41b of the groove 32 are engaged. The upper wall portion 12 and the lower wall portion 22 can be connected. The distance between the upper and lower wall portions can be freely adjusted by appropriately changing the convex portions 31 fitted into the stoppers 41a and 41b. Thereby, it can respond to each user's physique (finger thickness) and liking (fitting feeling of a finger operation auxiliary tool).

  Note that the shape of the grasping unit 23 is not limited to a sphere, and may be, for example, an elliptic sphere (egg shape, see FIG. 5B), another shape having a curved surface, or a polyhedron (regular dodecahedron, etc.) shape. It doesn't matter. Moreover, although the upper wall part 12 is the shape curved in the upward direction, it is not limited to this, You may be flat form like Fig.5 (a). Further, the width of the first upper wall portion 12a (second upper wall portion 12b) and the first lower wall portion 22a (second lower wall portion 22b) is also the first lower wall portion 22a (second lower wall) as described above. The wall 22b) is not limited to a wider configuration. As shown in FIG. 5A, the first upper wall portion 12a (second upper wall portion 12b) and the first lower wall portion 22a (second lower wall portion 22b) may have substantially the same width. . Further, the lower wall portion 22 may be a hard material such as plastic, but since it is a portion that comes into contact with the finger more strongly, it is very preferable to use a soft material such as rubber or a soft resin.

  Moreover, you may provide two right-and-left end clamping wall parts which each connect the left-right both ends of the upper wall part 12, and the both ends of the left-right direction of the lower wall part 22. As shown in FIG. In this case, the cross section of the upper part (portion other than the grasping part 23) of the finger movement assisting tool 1 has a shape obtained by rotating the “day” character by 90 degrees. By providing this end clamping wall portion, the finger motion assisting tool 1 can be more reliably attached to each finger. Further, it is preferable to use a soft material such as rubber as the material of the end clamping wall portion.

  In the above-described finger motion assisting tool 1, the configuration in which the grasping portion 23 is fixed to the lower surface of the lower wall portion 22 or attached by the grasping portion replacement convex portion 26 is described, but the present invention is not limited thereto. For example, like the finger movement assisting tool 10 shown in FIG. 6A, without providing the lower wall part 22, the stopper wall part 52 having the same shape as the upper wall part 12, the grasping part 23, You may comprise the stopper wall part 52 and the grasping part 23 with the clamping wall part 30 connected with a predetermined space | interval.

  In this case, the grasping part 23 may be directly attached to the holding wall part 30. That is, as shown in FIG. 6B, the holding wall portion 30 may be provided with a grasping portion replacement convex portion protruding downward, and the grasping portion 23 may be provided with a grasping portion replacement concave portion.

  Moreover, when the lower wall part 22 is not provided, the structure which integrally forms the clamping wall part 30 and the grasping part 23 using the same raw material (for example, rubber | gum) is also possible. Moreover, it is also possible to integrally form the stopper wall portion 52, the clamping wall portion 30, and the grasping portion 23 using the same material (for example, a soft material such as rubber).

  In addition, the usage method of this finger movement assistance tool 10 (FIG. 6A) is the same as that of the finger movement assistance tool 1 described above. That is, it is only necessary to insert two fingers into two recessed spaces surrounded by the stopper wall portion 52, the sandwiching wall portion 30 and the grasping portion 23. By omitting the lower wall portion 22, the lower wall portion 22 does not touch the finger when the finger is bent and stretched, and the finger movement assisting tool can be used more comfortably (without feeling uncomfortable). Further, the manufacturing cost can be reduced by integrating the respective parts.

  The technical idea of the first embodiment includes, for example, one that can be attached to one finger (for example, a wide ring formed of rubber or the like) or one that can be attached to a plurality of fingers (for example, In addition, a structure in which a grasping part (for example, an elastic body such as a sphere, an elliptical sphere, a hemisphere, or a polyhedron) is attached to or integrated with a glove-like object is included.

[Embodiment 2]
In the present embodiment, a finger movement assisting tool (a holding tool such as a writing tool) that effectively operates each finger by correctly holding a writing tool, chopsticks, and the like will be mainly described.

  Fig.7 (a) is a perspective view of the finger movement assistance tool which concerns on this Embodiment, (b) is the sectional drawing. The finger movement assisting tool 101 includes an upper wall portion 112 and a lower wall portion 122 that face each other, a sandwiching wall portion 130, and a grasping portion 123.

  The upper wall portion 112 and the lower wall portion 122 have a configuration in which two rectangular plate-like members are opposed to each other and gently bent in opposite directions. The sandwiching wall portion 130 is also a rectangular plate-like member, and the upper and lower wall portions 112 and 122 are connected at a predetermined interval. Here, the intersecting portion of the upper and lower wall portions 112 and 122 and the sandwiching wall portion 130 crosses the central portion of the upper and lower wall portions 112 and 122, and the normal of the upper wall portion 112 and the method of the lower wall portion 122 at the intersecting portion. The lines are almost orthogonal. Thereby, the space sandwiched between the upper wall portion 112 and the lower wall portion 122 is divided into two concave portions by the sandwiching wall portion 130, and a finger is inserted into each of the two concave portions.

  In the following, the direction from the lower wall portion 122 to the upper wall portion 112 is the upward direction, the direction from the upper wall portion 112 to the lower wall portion 122 is the downward direction, and the longitudinal direction of the plate-like members constituting the upper and lower walls 112 and 122 The direction is defined as the left-right direction. For example, the upper wall portion 112 has a shape along the top (convex downward).

  The upper wall 112 can be divided into two regions by the intersection of the upper wall 112 and the sandwiching wall 130, one of which is the first upper wall 112a and the other is the second upper wall 112b. To do. Similarly, the lower wall portion 122 can be divided into two regions by the intersection of the lower wall portion 122 and the sandwiching wall portion 130, one of which is the first lower wall portion 122a and the other is the second lower wall portion 122b. To do. Further, with respect to the first upper wall portion 112a or the second upper wall portion 112b, the length in the left-right direction (the length along the circumference) is referred to as the width of the first upper wall portion 112a or the second upper wall portion 112b. . Further, the length in the vertical direction of the sandwiching wall portion 130 is referred to as a distance between the upper and lower wall portions. Further, a concave space surrounded by the first upper wall portion 112a, the sandwiching wall portion 130, and the first lower wall portion 122a is divided into a first finger insertion portion (index finger insertion portion) 125a, a second upper wall portion 112b, and the sandwiching wall portion 130. A recess space surrounded by the second lower wall portion 122b is defined as a second finger insertion portion (middle finger insertion portion) 125b.

  A spherical grasping portion 123 is provided below the lower wall portion 122, and a part of the surface thereof is flush with the lower surface of the lower wall portion 122. The size of the grasping unit 123 is such that most of the grasping unit 123 can be surrounded by five fingers. It is preferable to use an elastic material such as rubber, urethane, foam (sponge) or silicon as the material of the grasping portion 123. Further, the surface may be made of rubber or urethane and gas or liquid may be filled therein, or a non-elastic material such as wood or plastic can be used.

  The width of the first upper wall portion 112a and the second upper wall portion 112a is somewhat shorter than the width of the index finger, the width of the first lower wall portion 122a is sufficiently longer than the width of the index finger, and the width of the second lower wall portion 122b is the index finger. It is a little longer than the width of. As a result, a surplus region 122y where the finger does not come into contact with the first lower wall portion 122a is formed, and an oblique recess 155 is formed at an end portion thereof (an end portion in the direction in which the finger is inserted).

  The length of the sandwiching wall portion 130 (upper and lower wall portions 112 and 122) in the finger insertion direction is such that the distance from the base of the index finger or middle finger to the first joint is sufficiently large. In addition, the distance between the upper and lower wall portions (the vertical length of the sandwiching wall portion 130) is set to be slightly larger than the thickness from the base of the index finger or middle finger to the first joint.

  Hereinafter, one usage pattern of the finger movement assisting tool 101 will be described.

  The user inserts the index finger and the middle finger into the first finger insertion part 125a and the second finger insertion part 125b of the finger operation assisting tool 101, and most of the index finger from the base of the index finger to the first joint is in the first finger insertion part 125a. The most part from the base of the middle finger to the first joint fits in the second finger insertion portion 125b. At this time, the holding wall portion 130 is sandwiched between the index finger and the middle finger, the first upper wall portion 112a is positioned above the index finger, the first lower wall portion 122a is positioned below it, and the second upper surface is positioned above the middle finger. The wall portion 112b is located, and the second lower wall portion 122b is located below the wall portion 112b. In addition, since the upper wall 112 has a shape that warps upward, even a user with a large finger does not feel cramped, and even a user with a small finger does not lose the fit. Each finger can be inserted into the second finger insertion portions 125a and 125b.

  Next, when holding the pencil, as shown in FIG. 8A, the user bends each finger and sandwiches the predetermined point W1 below the pencil with the thumb, index finger and middle finger, and is formed on the first lower wall portion 122a. The predetermined point W2 on the upper part of the pencil is placed on the oblique depression 155. At this time, the grasping part 123 is grasped slightly (to the extent that it is touched) with the thumb, ring finger, little finger, and part of the palm, and the angle between the pencil and the paper surface is set to 50 to 60 degrees. In the case of a ballpoint pen or a mechanical pencil, as shown in FIG. 8B, the angle between the pencil and the paper surface can be set to 70 to 80 degrees by holding the grasping portion 123 slightly stronger than the case of a pencil.

  As a result, an appropriate space can be forced inside the hand, and the index finger and thumb joints are naturally rounded. Therefore, the middle finger, ring finger, little finger should be bent slightly inward and the inside of the hand should be in the state of grasping the egg (point 1 (c)) or "do not put too much force on the index finger or thumb. Thus, it is possible to acquire effectively (forcibly, forcing) that the joints have roundness (point 2 (b)). By changing it, it can be used for pencils, ballpoint pens, mechanical pencils, etc. Furthermore, if you write with this correct way, all the 16 joints mentioned above will move effectively and increase the activation of the brain. it can.

At this time, it is felt that the grasping portion 123 is lightly grasped by a part of the thumb, middle finger, ring finger and palm, and the chopsticks can be easily and correctly held. If you eat in this way, all of the 16 joints described above will move effectively, and the activation of the brain can be enhanced.

  Next, as shown in FIG. 9A, in the case of holding a brush, the user bends each finger and sandwiches a predetermined point W1 in the middle of the brush with the thumb, forefinger and middle finger, and is formed on the first lower wall portion 122a. A predetermined point W2 at the upper part of the brush is brought into contact with the oblique depression 155. At this time, it is felt that the grasping portion 123 is lightly grasped by a part of the thumb, ring finger, little finger and palm. As a result, an appropriate space can be forced inside the user's hand and the brush can be held correctly.

  When the finger movement assisting tool 101 is sandwiched between the middle finger and the ring finger (the middle finger and the ring finger are inserted into the first finger insertion part 125a and the second finger insertion part 125b of the finger movement assisting tool 101), a brush and a paper surface The angle with can be changed. For example, when it is desired to change the angle between the brush and the paper surface by calligraphy, etc., the finger that sandwiches (wears) this finger movement assisting tool 101 is changed (for example, middle finger and ring finger, see FIG. 9B) or grasped. This can be dealt with simply by changing the gripping strength of the portion 123. Furthermore, if written in this correct way, all the 16 joints described above can effectively move and increase the activation of the brain.
