Description

[Technical field]

[0001] The present invention relates to a grip for a writing instrument that is attached to a writing instrument such as a pencil, mechanical pencil, or ballpoint pen, and more specifically to a grip for a writing instrument that allows a user to learn how to hold the writing instrument correctly or correct an improper way of holding the writing instrument by regulating the position and angle of the thumb, index finger, and middle finger in relation to the writing instrument when the user writes. [Background technology]

[0002] The way a child holds a writing implement is important when the child practices writing. Holding a writing implement improperly not only hinders the child's progress in writing, but also leads to problems such as poor physical posture. For this reason, many parents want to teach their children to hold writing implements correctly at an early stage. There are also many adults who feel inferior about the way they hold writing implements as a matter of etiquette, and who want to improve their writing skills and want to correct the way they hold writing implements.

[0003] In response to this, various prior art techniques have been proposed that can assist or correct the way a writing instrument is held by adding some kind of structure to the writing instrument itself or to the main body of an assisting device that can be attached to a writing instrument, for guiding or correcting the position or angle of the fingers.

[0004] For example, the writing aid described in Patent Document 1 and the grip posture correction pen described in Patent Document 2 induce a proper grip by holding the writing implement with all or any of the thumb, index finger, and middle finger in contact with a recess provided at a predetermined position on the shaft surface of the writing implement. However, children, especially infants who have just started to learn writing, have weak finger strength, and it is a burden for them to continue to hold the writing implement by spontaneously and continuously contacting the recess with their fingers. Therefore, writing implements and aids that are configured to induce and correct gripping only with such recesses have the problem that it is difficult for infants to practice writing for long periods of time. In addition, when recesses are simply provided on a writing implement, there is also the problem that, especially in the case of infants who are not accustomed to writing implements, the fingers do not necessarily contact the individual recesses appropriately, resulting in unexpected incorrect gripping.

[0005] In addition, the writing implement gripping correction tool of Patent Document 3 and the writing posture correction device of Patent Document 4 have an extension or wall that determines the angle and bending of the fingers in addition to a recess for the fingers to contact on the auxiliary tool attached to the writing implement, and can forcibly guide or correct the position and angle of the fingers by gripping the auxiliary tool. However, this gripping correction tool has a problem that it is difficult to accommodate users with different finger sizes and lengths, children who are growing rapidly, especially young children, because the auxiliary tool has a complex shape that forcibly fixes each part of the fingers, and it is difficult to use in educational settings. In addition, since it is unavoidable to feel that a foreign object is contacting each part of the fingers, there is a large discrepancy with the feeling of writing without the auxiliary tool, and it is not suitable for children after all.

[0006] On the other hand, the writing aid according to Patent Document 5 has a configuration in which a cylindrical body through which the writing instrument is attached has thumb and index finger slots into which the thumb and index finger can be inserted, and the middle finger is abutted against the recess. The writing instrument for grip training according to Patent Document 6 also has a ring inclined at a predetermined angle, into which only the tips of the thumb and index finger can fit, attached to the cylindrical body. These prior arts fix the position and angle of only the tips of the fingers using finger slots and rings, and allow for a certain degree of difference in finger size and length, and do not cause a foreign body sensation like the inventions and devices according to Patent Documents 3 and 4. However, since both prior arts are configured to fix the angle of the writing instrument relative to the first joint of the finger using finger slots and rings, there is a limit to how much they can accommodate differences in the length and thickness of the user's fingers, and they are not necessarily suitable for use by young children who are rapidly growing. [Patent Document 1] JP 2016-221926 A [Patent Document 2] Utility Model Registration No. 3151079 [Patent Document 3] JP 2004-181685 A [Patent Document 4] Utility Model Registration No. 3109564 [Patent Document 5] Utility Model Registration No. 3119250 [Patent Document 6] Japanese Patent Application Laid-Open No. 8-76683 DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0007] The present invention was created to solve the problems of the prior art. The problem to be solved by the present invention is to provide a grip for a writing instrument that allows even a child whose fingers are still weak, whose hands vary in size, and who is still growing rapidly, to learn the correct gripping method naturally and effortlessly, without feeling any burden or foreign body sensation when using it. More specifically, the present invention aims to provide a low-cost grip for a writing instrument that has features not found in the prior art, which allows the three fingers, the thumb, index finger, and middle finger, which determine the way to hold a writing instrument, to be placed in the correct position on the writing instrument, without excessively forcibly fixing the angle or bending of each finger, and can be adapted appropriately according to the length and thickness of the fingers. [Means for solving the problem]

[0008] In order to solve the above problems, the invention according to claim 1 is a grip for a writing instrument for forming a habit of holding the writing instrument in a proper manner, the grip having an outer circumferential surface of a substantially cylindrical main body made of a soft elastic body having a through hole through which the writing instrument can be passed and fixed, the grip having a thumb recess against which the tip of the thumb can rest, an index finger recess against which the tip of the index finger can rest, a middle finger recess against which the inner surface of the middle finger can rest, and both or either of a thumb ring made of a soft elastic string through which the thumb can be inserted and fixed, and an index finger ring made of a soft elastic string through which the index finger can be inserted and fixed, The present invention is characterized by comprising:

[0009] The invention according to claim 2 is a grip for a writing instrument as described in claim 1, characterized in that a rib against which the inner surface of the middle finger can abut is provided at a position toward the rear of the middle finger recess.

[0010] The invention of claim 3 is a grip for a writing instrument as described in either claim 1 or claim 2, characterized in that the thumb ring has a front end of a string attached to the lower part of the outer right side of the main body near the front end and a rear end attached to the upper part of the outer right side of the main body near the rear end, and the index finger ring has a front end of a string attached to the lower part of the outer left side of the main body near the front end and a rear end attached to the upper part of the outer left side of the main body near the rear end.

[0011] The invention according to claim 4 is also a grip for a writing instrument as described in claim 1 or claim 2, wherein the main body includes the thumb recess, the index finger recess, and the middle finger recess, and comprises a front main body to which the front ends of the thumb ring and the index finger ring are attached, and a rear main body to which the rear ends of the thumb ring and the index finger ring are attached, which are configured to be separable or attachable to the writing instrument, and the thumb ring has a front end attached to the lower part of the outer circumferential right side surface of the front main body near the front end and a rear end attached to the upper part of the outer circumferential right side surface of the rear main body near the rear end, and the index finger ring has a front end attached to the lower part of the outer circumferential left side surface of the front main body near the front end and a rear end attached to the upper part of the outer circumferential left side surface of the rear main body near the rear end.

[0012] The invention of claim 5 is the grip for a writing instrument as described in claim 3, wherein the main body includes the thumb recess, the index finger recess, and the middle finger recess, and a front main body to which the front ends of the thumb ring and the index finger ring are attached, and a rear main body to which the rear ends of the thumb ring and the index finger ring are attached are configured to be separable or combinable in the same phase with respect to the writing instrument, and the thumb ring has a front end of a string attached to a lower part of the outer circumferential right side surface of the front main body near the front end and a rear end of the string attached to an upper part of the outer circumferential right side surface of the rear main body near the rear end, and the index finger ring has a front end of a string attached to a lower part of the outer circumferential left side surface of the front main body near the front end and a rear end of the string attached to an upper part of the outer circumferential left side surface of the rear main body near the rear end.

[0013] The material of the main body is not particularly limited as long as it is a soft elastic body of a substantially cylindrical shape having a through hole, but considering that it is directly in contact with a person's fingers for a long time and that soft elastic elastomers have problems such as deterioration of the material and sticky surfaces due to long-term use, silicone rubber having moderate elasticity is preferable. The cross-sectional shape of the through hole is basically preferably circular, but is not necessarily limited to this, and even if the diameter varies slightly depending on the writing instrument to be applied, or the cross section is a triangle, hexagon, or ellipse other than a circle, it is necessary that the through hole has a cross-sectional shape, inner diameter, and elasticity that can be tightly fixed within the through hole, and that a moderate frictional force acts on the writing instrument so that the fixed position does not shift inadvertently, and that can be easily attached and detached.

[0014] In addition, by providing both the thumb ring and the index finger ring, or either one of them, the thumb and index finger or either one of them is passed through the appropriate ring, and then the fingertips are placed in the thumb recess and index finger recess, so it is clear which recess the thumb and index finger should be placed in, and if the thumb and index finger are placed correctly in the thumb recess and index finger recess, the middle finger will naturally be placed in the middle finger recess. This prevents a child who is not familiar with writing instruments from holding the writing instrument in an unexpected manner by mistake. Note that the thumb ring and the index finger ring are both configured to guide the fingertips to naturally be placed in the appropriate recess by passing the fingers through them, and are not configured to forcibly bind the user's fingers to the writing instrument. Depending on the user's habit of holding the writing instrument, if the thumb or index finger is placed in the appropriate recess, the other fingers may naturally be placed in the appropriate position, allowing the user to hold the writing instrument correctly. Therefore, it is preferable to provide both rings, but this is not necessarily limited to this, and only one of the rings may be provided depending on the user.

[0015] The thumb recess, index finger recess, and middle finger recess are respectively abutted with the pad of the thumb tip, pad of the index finger tip, and the inner surface of the tip of the middle finger from the first joint, thereby positioning each fingertip in the correct grip of the writing instrument. In addition, in the writing instrument grip according to claim 2, the pad side of the middle finger is further abutted against the rib, thereby preventing the middle finger from accidentally slipping out of the middle finger recess.

[0016] In the writing implement grip according to claim 3, the thumb ring and index finger ring are both string-like. By making the rings string-like, the rings come into linear contact with the front side of the thumb and index finger near the first joints, making it possible to fix both fingers in the appropriate position with a minimum contact area. The material of the thumb ring and index finger ring is preferably silicone rubber, just like the main body, but if both rings are made of a material that is slightly softer and more stretchable than the main body, it will be possible to absorb differences in finger thickness depending on the user and make them fit the fingers better.

[0017] Furthermore, if the thumb ring and index finger ring are both colored in an appropriate color different from the main body, it will be clearer to even small children holding a writing utensil for the first time where they should insert their thumb and index finger, making it easier for them to learn how to hold the writing utensil correctly.

[0018] Furthermore, in the writing instrument grip according to claims 4 and 5, the main body is divided into a front main body and a rear main body that can be separated or combined. By adopting such a configuration, it is possible to move only the rear main body backward as necessary while the writing instrument grip is attached to the writing instrument. Therefore, the distance between both ends of the thumb ring and the index finger ring, which are attached at their front ends to the front main body and at their rear ends to the rear main body, can be changed, so that the force and position of the fingers fixed by each ring can be finely adjusted. This, combined with the elasticity of both rings, makes it possible to fix both fingers optimally for the user by further following the difference in finger thickness and length, and can accommodate changes in the fingers due to the growth of infants and the like for a longer period of time. In the writing implement grip of claim 4, the phase (the mutual angle between the front body and the rear body with the axis of the writing implement as the axis of rotation) when the separate front and rear bodies are combined is arbitrary, and by shifting the phase, the positional relationship between the front and rear ends of each ring can be changed, allowing the user to fine-tune the way each ring touches the finger as needed. On the other hand, in the writing implement grip of claim 5, the phase when the front body and the rear body are combined is fixed to a single value, preventing users such as small children from carelessly shifting the phase.

[0019] In addition, the structure in which the main body is divided into a front main body and a rear main body has the following advantages in terms of manufacturing. That is, the writing implement grip according to the present invention is structured by using a soft material such as silicone rubber and attaching two rings, a thumb ring and an index finger ring, to the main body. For example, it is possible to complete the product by gluing the main body and the rings together after molding them separately, but this manufacturing method not only requires the time-consuming gluing process, but also makes it difficult to maintain the quality of the adhesion, resulting in poor yield. It is also possible to integrally mold the main body and the rings by injection molding, but this is technically difficult and expensive. Moreover, if the main body and the two rings are molded from different materials, the cost will be even higher. On the other hand, compression molding using a single mold (one set of male and female) is generally the lowest cost. However, even in this case, since the string-like rings are three-dimensionally curved and protruding, if compression molding is performed on the rings as they are, the mold will have a three-dimensionally complicated structure, and the cost will still be high.

[0020] To solve this problem, if a mold is used in which the main body is divided into a front main body and a rear main body, the axis of the rear main body is rotated 90° relative to the axis of the front main body, and two rings are arranged to straddle the front main body and the rear main body, the two rings that are curved three-dimensionally can be molded in a two-dimensional manner on a plane parallel to the axis of the main body, so that the writing grip according to the present invention can be integrally molded by compression molding using a single mold. Moreover, with compression molding, different materials can be placed in the cavity of the main body part and the cavity of the two ring parts on the mold before molding, and integral molding can be performed in a single process, so not only can costs be reduced, but also desired materials can be used arbitrarily depending on the color and hardness of the main body and the rings. Effect of the Invention

[0021] The grip for a writing instrument according to the present invention has the following special effects. (1) By providing the thumb ring and the index finger ring, the main body can be always fixed to the fingers with the thumb, index finger, and middle finger in contact with the corresponding recesses, so that even small children who have weak finger strength and are not accustomed to writing can hold the writing instrument in the correct grip for a relatively long period of time without feeling any strain, improving learning efficiency. Also, depending on the user's habit of holding the writing instrument, such an effect may be expected even if only one of the thumb ring and the index finger ring is provided. (2) The thumb ring and index finger ring are made of elastic strings, so that the fingers are not excessively constrained and there is little feeling of a foreign body. This allows the user to grasp the writing instrument in a correct manner that suits the thickness and length of the fingers, in a manner close to a natural grip without using a writing instrument grip, and allows the user to form a habit of grasping the writing instrument in this manner. (3) The main body of the writing instrument grip is configured so that it can be separated or combined into a front body and a rear body. As a result, the force with which the fingers are fixed can be fine-tuned by changing the distance between both ends of the thumb ring and the index finger ring as needed, enabling the user to fix both fingers in an optimal state according to differences in finger thickness and length, and the grip can be adapted over a long period of time to changes in the fingers as an infant grows. (4) The main body of the writing instrument grip is configured so that it can be separated or combined into a front main body and a rear main body. Therefore, by compression molding using a single mold, the grip main body and two rings can be molded as a single unit even if the materials or colors of the grip main body and two rings are changed, thereby reducing manufacturing costs.

[0023] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a perspective view showing a state in which a writing instrument grip 1 according to one embodiment of the present invention is attached to a writing instrument W, and Fig. 2 is a perspective view of the writing instrument grip 1 alone. Note that the writing instrument W in Fig. 1 is assumed to be a mechanical pencil with a circular shaft cross section, but the writing instrument W is not limited to this, and the writing instrument grip 1 can be applied to writing instruments with various cross-sectional shapes such as pencils and ballpoint pens.

[0024] Figures 3 to 6 are oblique views showing the front body 10 and rear body 20 of the writing instrument grip 1 separated, with Figure 3 being a view from above the front, Figure 4 being a view from above the rear, Figure 5 being a view from below the front, and Figure 6 being a view from below the rear.

[0025] 7 to 12 are six-view diagrams of the writing instrument grip 1. Fig. 7 is a front view, Fig. 8 is a rear view, Fig. 9 is a left side view, Fig. 10 is a right side view, Fig. 11 is a plan view, and Fig. 12 is a bottom view, and in Figs. 7 to 10, the upper views show the combined state of the main bodies and the lower views show the separated state, and in Figs. 11 and 12, the left views show the combined state of the main bodies and the right views show the separated state.

[0026] The writing implement grip 1 comprises a substantially cylindrical body formed by coaxially combining a front body 10 and a rear body 20, each of which has a through hole 11 and a through hole 21 of the same diameter, and a thumb ring 15 and an index finger ring 16, the front end of which is attached to the front body 10 and the rear end of which is attached to the rear body 20, respectively.

[0027] The material of the front body 10 and the rear body 20 is a relatively hard silicone rubber so that they do not easily deform when writing. The shape of the through holes 11 and 21 is circular, but is not limited to this, and the inner surface is made to be able to be fixed in close contact with the writing implement W, and the fixed position is not accidentally shifted, and the cross-sectional shape and inner diameter are made to be able to be easily detached. In this embodiment, a notch 18 is provided at the upper rear end of the front body 10, and a protrusion 22 corresponding to the shape of the notch 18 is provided at the upper front end of the rear body 20. By fitting the protrusion 22 into the notch 18, the front and rear bodies can be combined without shifting in phase, so that the positional relationship between the three recesses and the two rings can always be kept appropriate, and even if a gap is provided between the front and rear bodies as necessary, it can be used as a guide to align the phases of the front and rear bodies.

[0028] In this embodiment, the thumb ring 15 and the index finger ring 16 are string-like and are integrally molded with the two main bodies. They are softer and more stretchy than the main bodies, and different colored silicone rubber is used for the thumb and index finger rings, but this is not limited to this and silicone rubber of the same material and color as the main bodies may be used.

[0029] The thumb ring 15 has its front end fixed to the lower right side surface near the front end of front body 10 and its rear end fixed to the upper right side surface of rear body 20, and the index finger ring 16 has its rear end fixed to the lower left side surface near the front end of front body 10 and its rear end fixed to the upper left side surface of rear body 20. When the bodies are combined, each ring is curved in an approximately S-shape from front to rear when viewed from the side, allowing the thumb and index finger that are inserted into each ring to be fixed in place by the elasticity of the ring.

[0030] The front body 10 has three recesses, a thumb recess 12 on the upper right side, an index finger recess 13 on the upper left side, and a middle finger recess 14 on the bottom. All three recesses are approximately elliptical along the axial direction of the body, the thumb recess 12 and the index finger recess 13 have curved surfaces corresponding to the shape of the pad of the fingertip to be placed, and the middle finger recess 14 has a curved surface corresponding to the shape of the inner surface of the middle finger from the first joint to the tip to be placed. The three recesses are arranged at intervals of approximately 120° from each other when viewed from the front. Illustrations representing each finger may be displayed on the inner surfaces of the thumb recess 12 and the index finger recess 13, so that the child can see at a glance where each finger should be placed.

[0031] A rib 17 is provided at a position toward the rear of the middle finger recess 14. The rib 17 is configured to fix the position of the middle finger in contact with the middle finger recess 14, and in this embodiment, the rib 17 is shaped to rise in a continuous curved surface from the left front to the right rear of the middle finger recess, so that the pad side of the middle finger can be abutted against the rib and fixed so that the middle finger does not slip out of the middle finger recess during writing. The rib 17 is not limited to a curved rib shape as in the embodiment, and may be a ring shape that allows the middle finger to pass through.

[0032] 13 to 15 are views showing a state in which a writing implement W to which a writing grip 1 is attached is gripped, with FIG. 13 being a perspective view seen from the front, FIG. 14 being a right side view, and FIG. 15 being a plan view.

[0033] By inserting the thumb through the thumb ring 15 and abutting against the thumb recess 12, inserting the index finger through the index finger ring 16 and abutting against the index finger recess 13, and then abutting the middle finger against the middle finger recess 14, the pad of the middle finger naturally abuts against the front surface of the rib 17. At this time, the thumb ring 15 and the index finger ring 16 abut against the curved surfaces of the thumb and index finger from in front of the first joint to near the base of the nail, respectively, and the position of the fingers is fixed by the elasticity of the rings. This allows the user to unconsciously grip the writing implement W in the correct way.

[0034] By attaching the writing grip 1 to the writing instrument W, children can naturally grasp the writing instrument correctly simply by passing their thumb and index finger through the rings, so even small children who have just started to use writing instruments will not get confused about how to use it. In addition, because the thumb and index finger are always fixed to the writing instrument W by the two rings, children will not accidentally drop the writing instrument W or change their grip even if they are not constantly exerting force on their fingers, so it is possible to form the habit of grasping the writing instrument correctly at an early stage.

[0035] Furthermore, by moving the rear body 20 backwards while the writing grip 1 is attached to the writing implement W, the distance between both ends of the thumb ring and index finger ring can be changed as needed, allowing fine adjustment of the strength with which each ring secures the thumb and index finger. This allows the user to secure both fingers in an optimal state according to differences in finger thickness and length, and can accommodate long-term changes in the fingers as children grow.

[0036] When the writing grip 1 is molded as a single piece, the front body 10 and the rear body 20 are separated, and a mold is used in which the axis of the rear body 20 is rotated 90°. This allows two rings that form a three-dimensional, roughly S-shape when the bodies are combined to be molded in a cavity on the same plane as the cavity for the body of the mold. Therefore, the writing grip 1 can be molded as a single piece by low-cost compression molding, making it easier to promote its widespread use.

[0037] In addition, in the manufacturing process of the writing implement grip 1, by putting different silicone rubber materials into the cavity for the main body and the cavities for the two rings, it is possible to integrally mold the main body and the two rings with different combinations of hardness and color. This allows the thumb ring 15 and the index finger ring 16 to be different colors so that young children can learn where to pierce their fingers by the difference in colors, and also makes it possible to provide colorful products at low cost.

[0038] The above describes an embodiment of the present invention with reference to the drawings. However, the present invention is not necessarily limited to the above-described configuration, and can be modified and implemented as appropriate within the scope of the invention, which achieves the object of the invention and has the effect. As long as it falls within the scope of the technical idea of ​​the present invention, it belongs to the technical scope of the present invention. [Industrial Applicability]

[0039] The writing implement grip of the present invention can be used mainly for young children who are handling a writing implement for the first time to learn how to hold the writing implement correctly at an early stage, and therefore can be widely used as one of the educational stationery items in homes, nurseries, kindergartens, etc. In addition, it can be used for self-study by adults who feel inferior about the way they hold a writing implement as a matter of etiquette or who wish to improve their writing skills and correct the way they hold a writing implement, and therefore can be widely used as one of the general stationery items.
