Description

TECHNICAL FIELD

[0001] The present application relates to the field of learning supplies, in particular to a pen with a pen holding posture correcting assembly and a pen with a posture correcting function. BACKGROUND

[0002] Incorrect writing posture not only makes children feel tired and the writing not beautiful, but also causes myopia, pain and even deformation of the middle finger and index finger, affects the development of the wrist and spine, and thus causes irreversible damage. Therefore, it is very important to develop a correct pen holding posture. The correct pen holding posture is that the thumb, index finger and middle finger are naturally bent at about 3cm from the pen tip and hold the pen from three directions, the thumb tip is opposite to the index finger palm without being connected, the middle finger nail cover inner side is against the pen barrel, the ring finger and little finger are naturally bent and sequentially supported under the middle finger, the little finger cannot touch the palm, the pen barrel upper end is inclined at the third joint root of the index finger, the pen barrel is inclined more than 50 degrees to the right rear, the wrist is straight, and cannot be hooked or turned out.

[0003] In recent years, various types of correction tools have appeared to help children guide and correct the pen holding posture. The main implementation way is to use a sleeve set with a finger placement area on the pen barrel, or to set the pen structure shape so that the pen body contains a finger placement area, and the design form of the above finger slot is also various. However, there are still problems with the above correction technology: (1) one design of the finger slot area is that the index finger slot area and the thumb slot area extend in a tangential direction relative to the circumference of the pen, and the index finger slot area is closer to the pen tip end, which presents a rising structure. This may cause the thumb and index finger to be misaligned in the upward and downward directions, and the force on the fingers is uneven, resulting in a deviation of the force point, muscle tension, and long-term use which is not conducive to the development of correct pen holding posture; (2) a pen sleeve or a finger slot that can embed fingers is usually set on the pen barrel. This type of product still has some problems in the design of the finger slot, and there is a possibility of deformation during the sleeve setting process. When the pen sleeve is removed, it is still difficult for children to maintain the correct pen holding posture. In addition, the pen sleeve is bulky in shape and affects the writing line of sight. In addition, the ring-shaped structure on the finger head may pull the finger head and affect the health of the finger joints; (3) the coordination and consistency of the hand pen holding posture are not considered as a whole, and more attention is paid to the design of the thumb, index finger and middle finger, while the upper end of the pen barrel is ignored to be inclined at the third joint root of the index finger. Therefore, the hand muscle pain caused by over-tightening of the hand muscle cannot be changed. SUMMARY

[0004] In order to solve the problems of the unscientific design of the existing finger groove position and the shape of the correcting pen and the neglect of the fact that the upper end of the pen barrel should be inclined to rest on the third joint of the index finger in the technical background, the present application provides a correcting pen which meets the principle of ergonomics and has the advantages of reasonable structure design, uniform force point, scientific pen holding posture, good comfort and the like.

DETAILED DESCRIPTION

[0048] ​In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not intended to limit the present application. In addition, the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0049] As shown in Figure 1 The present application first discloses a pen holding posture correcting assembly, wherein the pen holding posture correcting assembly comprises a pen holding segment 1 and a web segment 2 in sequence relative to a writing end, wherein the pen holding segment 1 and the web segment 2 can be in the form of mutual connection or in the form of segmented setting.

[0050] The pen holding segment 1 is provided with a first pen holding area 11 and a second pen holding area 12, which are distributed on the pen holding segment and respectively have a first type of concave structure for indicating the position of the pen holding finger pad. At least one web area 21 is provided on the web segment 2 and has a second type of concave structure for indicating the position of the pen holding web. The first type of concave structure and the second type of concave structure involved in the above-mentioned assembly are concave relative to the surface of the cylindrical pen barrel in the use case, which is recessed towards the shaft axis, so that the function of clearly indicating the three-zone positioning of the pen holding can be realized. Through the "three-zone", the writing tool can be positioned in the hand in a more natural pen holding posture, and at the same time, the contact surface between the web area 21 and the hand is increased, so that it can be firmly inclined at the correct position of the index finger root. That is, the above-mentioned three-zone forms the positional relationship between the pen holding area and the web area on the opposite sides of the pen barrel structure of the assembly in the process of indicating the pen holding positioning.

[0051] Regarding the circumferential symmetry of the pen holding area in the present application, in the pen holding posture correcting assembly, the positional relationship and structural symmetry of the pen holding area are mainly described. Firstly, the heights of the two pen holding areas corresponding to the axial direction of the assembly are one-to-one corresponding. Secondly, the concave structures of the two pen holding areas are also one-to-one corresponding and symmetrical in spatial structure. Since the pen holding posture correcting assembly is generally designed as a pen sleeve or directly as one part of the pen structure, although it is not strictly a cylindrical structure, the circumferential indication is perpendicular to the cross section of the axial direction of the assembly.

[0052] Regarding the web area in the present application, generally speaking, the web refers to the maximum distance between the tip of the thumb and the tip of the index finger when the palm is fully opened. The web area is also the area from the tip of the index finger to the tip of the thumb in a broad sense. In the state of pen holding and writing, the healthy posture is that the pen barrel leans on the joint of the index finger root. In fact, in the case of using the above-mentioned assembly, the user may lean the web segment on one of the joints from the index finger root to the thumb root. As the setting of the web area of the present application, the healthy posture point of the web area when holding the pen is indicated.

[0053] The present application has a curvature-changing concave step structure at the junction between the web space in the web section and other parts, that is to say, the non-web area of the web section has a gradually increasing trend from the outer diameter of the writing end, and has a larger curvature concave structure at the first end of the web space, thereby forming a concave step change, which can enhance the leaning memory of the index finger joint, and thus can quickly achieve a natural and healthy pen-holding posture. In a pen-holding posture, the joint of the base of the index finger abuts against the part of the concave step structure.

[0054] As shown in Figure 1 and 2 , the first pen-holding area 11 and the second pen-holding area 12 are symmetrical with respect to the central axis cross section of the assembly, and in the corresponding embodiment of the present application, the assembly has a central axis cross section along the central axis, and the two pen-holding areas have a symmetrical structure with respect to the central axis cross section. The axis cross section is a "face" passing through any one axis, and the central axis cross section is a face passing through the central axis, i.e. the AB face; the symmetrical relationship means that the first pen-holding area 11 and the second pen-holding area 12 are not only symmetrical in positional relationship, but also one-to-one symmetrical in spatial concave structure. In the design of the existing pen-holding posture correction pen, the structure design of the index finger corresponding pen-holding area is generally closer to the writing end than that of the thumb corresponding pen-holding area, or the structure design of the pen-holding area not only extends in the axial direction, but also extends at a certain angle in the radial direction of the pen barrel surface. First, the symmetrical design is more suitable for left-handed and right-handed pen-holding design, and the symmetrical design does not specifically emphasize the closer or less close to the writing end of the index finger and the thumb in the axial direction, so that the user can more flexibly master the pen-holding angle of the index finger and the thumb in the pen-holding posture and be more suitable for different finger length proportion pen-holding postures in the use of pen-holding posture correction.

[0055] The symmetrical arrangement of the two pen-holding areas leaves space for the middle finger joint leaning area in other positions in the pen-holding section when holding the pen.

[0056] For the above pen-holding posture correction assembly, the overall rod-shaped design has a structure as shown in Figure 3 ,

[0057] The first pen-holding area 11 and the second pen-holding area 12 have a first radial pen-holding peripheral surface 111 at the first end of the pen-holding area along the axial direction, and have a second radial pen-holding peripheral surface 112 at the second end of the pen-holding area.

[0058] The second radial pen-holding peripheral surface area 112 is larger than the first radial pen-holding peripheral surface area 111, the first end is the end closer to the writing end, and the second end is the end farther from the writing end.

[0059] The outer diameter of the second radial pen-holding circumferential surface 112 is greater than that of the first radial pen-holding circumferential surface 111. The first type of concave surface structure of the pen-holding area is designed in cooperation with the overall structure of the pen barrel. The outer diameter of the pen barrel corresponding to the pen-holding end 1 increases gradually from small to large. When the pen is held, the angle between the index finger and the thumb is naturally indicated.

[0060] The first end of the corresponding web segment 2 of the web area 21 in the axial direction has a first radial web circumferential surface 211, and the second end of the web area 21 has a second radial web circumferential surface 212. The area of the second radial web circumferential surface 212 is smaller than that of the first radial web circumferential surface 211. The first end of the web area 21 is the end close to the writing end, and the second end of the web area 21 is the end away from the writing end.

[0061] The outer diameter of the first radial web circumferential surface 211 is slightly greater than that of the second radial pen-holding circumferential surface 212. The second type of concave surface structure of the web area is designed in cooperation with the overall structure of the pen barrel. The outer diameter of the pen barrel corresponding to the web segment 2 decreases gradually from large to small. When the pen is held, the placement position of the web area is naturally indicated.

[0062] The slightly greater numerical range is 1% to 5%.

[0063] The length of the pen-holding area from the second end of the pen-holding area to the first end of the pen-holding area is between one-half and two-thirds of the length of the pen-holding segment 1. The overall length of the pen-holding area should not be too long. In the natural state of holding the pen, the position of the finger pad does not occupy too long a distance of the pen-holding segment. A reasonable length of the pen-holding area can indicate the force position of the finger pad in the pen-holding posture. A longer length of the pen-holding area may indicate excessive flexion of the knuckles, which affects the health of the pen-holding posture.

[0064] The length of the web area 21 is two-thirds or more of the length of the web segment 1. In the design of the pen barrel, the second type of concave surface structure corresponding to the web indicates the position of the web in the pen-holding state. At this time, the first part of the second type of concave surface structure leans on the joint of the finger, and the corresponding part at the lower folding point N leans on the joint of the finger.

[0065] As the first type of concave surface structure of the present application, the specific position of the finger pad in the pen-holding area is indicated. The pen-holding area includes at least two parts of curved surface structure, which are separated in the Z direction (the axial direction of the pen barrel).

[0066] As Figure 8As shown, the first type concave structure is divided into two parts from the radial cross-sectional direction, the first part (the part close to the writing end) has at least a third average curvature, and the second part (the part away from the writing end) has at least a fourth average curvature, the absolute value of the third average curvature is smaller than the absolute value of the fourth average curvature, that is, the first type concave structure has a more smooth curve on the side closer to the writing end, and a more "steep" curve design on the part farther away from the writing end, so that the pen holding area indicates a more relaxed joint holding state.

[0067] The height ratio of the first part to the second part in the axial direction (Z-axis) is 1:1.1-2.

[0068] The first type concave structure is divided into two parts from the axial cross-sectional direction, the first part (the part close to the two finger closer area) has at least a fifth curvature, and the second part (the part away from the two finger closer area) has at least a sixth curvature, that is, the first type concave structure has a more smooth curve on the side closer to the two finger closer area, and a more "steep" curve design on the part farther away, so that the pen holding area indicates a more relaxed joint holding state, and the more "steep" curve design indicates the pen holding boundary of the pen holding posture.

[0069] The width ratio of the first part to the second part in the radial direction is 1:1.1-2.

[0070] It is worth noting that the above-mentioned average curvature refers to the average curvature of the macroscopic surface of the corresponding area. In the corresponding concave structure, some structures with small protrusions or corrugated structures that increase the friction of the finger groove area can be provided. The protrusions of the above structure design do not exceed the outer circumferential segment of the concave structure, so as not to cause the feeling of strangeness of holding the pen. The connection part between the curvatures of the two parts can also be other curvature connection settings to enhance the pen holding indication of the pen holding area. The average curvatures of the two parts are preferably smoothly transitioned.

[0071] The second type concave structure has at least a first average curvature close to the writing end, and at least a second average curvature away from the writing end, the first average curvature is greater than the second average curvature, the second type concave structure has a more "steep" curve on the side closer to the writing end, and a more "smooth" curve design on the part farther away from the writing end, so that the structure at the lower folding point N of the web space area realizes the embedding of the index finger tail of the finger joint, so that the position indication area of the web space feels more intense, guiding the pen holding posture.

[0072] The preferred range of the curvature is that the first average curvature is 1.5-3 times, preferably 2 times, of the second average curvature. In this way, the part of the volar crease section of the assembly and the part of the second type of concave structure of the volar crease form a concave stepped structure with a change in curvature (that is, the part of the volar crease section and the part of the volar crease have an inflection point of curvature, a sudden change, the part of the volar crease section is gradually increased in the axial upward part of the cross-sectional outer periphery, and the first curvature section of the volar crease has a concave), indicating the volar crease leaning area of holding a pen, indicating the volar crease leaning area of holding a pen, so that in the standard holding posture, the indication of the distal phalangeal joint of holding a pen can be enhanced, and the standard holding posture can be formed.

[0073] In the comparison of the curvature, the absolute value of the curvature is generally used, and the size of the absolute value indicates a more smooth or more steep concave design, that is, the above-mentioned curved structure design generally refers to the curved surface structure of the surface concave with respect to the rod body, so as to facilitate the indication of the internal concave structure of the volar crease area and the volar crease area.

[0074] The second type of concave structure is divided into two parts from the axial tangent plane direction, and has a structure with substantially symmetrical two parts.

[0075] In another embodiment of the present application, a writing posture correcting assembly is disclosed, and a pen head section is connected to the writing posture correcting assembly, and is used to arrange a writing core.

[0076] The upper and lower ends of the writing posture correcting assembly are detachably connected, the volar crease section and the cap section are detachably connected or non-detachably connected, and the connection mode can be screw rotation or pullable.

[0077] In a specific embodiment, as shown in Figure 9 , the correcting pen is vertically perpendicular to the axis, and is mirror-symmetric, and the symmetry plane is the AB plane; as shown in Figures 4-5 , the cross sections of the pen head section, the writing posture correcting assembly, the volar crease section, and the cap section are isosceles curved triangles or equilateral curved triangles, the first writing area and the second writing area are respectively located on the outer sides corresponding to the two isosceles parts of the isosceles curved triangle, the corners are rounded, and the edges are arc edges. Figure 10 In a specific embodiment, the pen barrel is a pen provided with the writing posture correcting assembly, and the cross section of the pen barrel is a circle. Figure 11 and Figure 12 are Figure 10The middle pen barrel is the overall appearance view in the pen setting embodiment of the above-mentioned pen holding posture correcting assembly, and the pen buckle and the pen cap can be combined to design an animal shape. The cross section of the posture correcting pen is circular, which can form a more full pen holding feeling when holding the pen, and the leaning part of the middle finger joint corresponds to the arc-shaped outer side in the part other than the pen holding area, so that the holding indication memory of the middle finger is enhanced.

[0078] As shown in Figure 9 , a space rectangular coordinate system is set with the pen core tip P as the origin, the X axis and the Z axis are on the AB plane, the Y axis is perpendicular to the AB plane, the first pen holding area 11 is mostly located in the first quadrant, the second pen holding area 12 is mostly located in the second quadrant, and the web area 21 is located in the third and fourth quadrants.

[0079] The positions of the first pen holding area 11, the second pen holding area 12, and the web area 21 are "three areas standing" about the Z axis, so that the correcting pen can be better positioned in the hand through the "three areas", and at the same time, the contact surface of the web area 21 with the hand is increased, so that it is firmly inclined at the base of the index finger.

[0080] As shown in Figure 2 and 4 , the first pen holding area 11 and the second pen holding area 12 are symmetric about the AB plane but not connected, so that the fingers are opposite but not connected, the force is uniform, and the muscles are relaxed.

[0081] As shown in Figure 3 and 5 , the web area 21 itself is symmetric about the AB plane.

[0082] As shown in Figure 6 , the first pen holding area 11 and the second pen holding area 12 are connected with the pen holding segment pen barrel area 13 through a smooth curved surface, so as to form a one-piece curved surface structure.

[0083] As shown in Figure 3 and 7 , the web area 21 is connected with the web segment pen barrel area 22 through a smooth arc-shaped groove, and the web area 21 and the web segment pen barrel area 22 have an upper folding point M and a lower folding point N at the connection, so as not to form a one-piece curved surface structure.

[0084] As shown in Figure 6 , the first pen holding area 11 is a smooth concave arc surface, the front surface is oval-shaped, and is radially inclined relative to the pen barrel axial direction, the inclination direction is relative to the negative direction of the X axis, and the inclination angle is 30°. According to ergonomics, the curved surface equation of the first pen holding area 21 is:

[0085] Meanwhile, the second grip pen area 12 is a smooth concave arc surface, the front surface is oval, and is arranged in an axial direction and a radial direction relative to the pen barrel, the inclined direction is relative to the negative direction of the X axis, and the inclined angle is 30°. According to ergonomics, the curved surface equation of the second grip pen area 12 is: wherein c > a > b are constants.

[0086] As shown in Figure 7 , the web area 21 is a smooth concave arc surface, the front surface is an isosceles triangle, and the corners of the triangle are rounded and the sides are curved. The web area 21 is arranged in an axial direction relative to the pen barrel, and is not inclined in a radial direction. According to ergonomics, the curved surface equation of the web area 21 is: wherein c0> 3a0> 3b0are constants.

[0087] The surface material of the first grip pen area 11, the second grip pen area 12, and the web area 21 can be an elastic material, and a soft pad, a texture, or a marker color can be arranged. The surface material can be a concave structure formed integrally with the pen barrel, or a concave structure formed by a corresponding flexible gasket.

[0088] The pen head section 3 is divided into a pen head refill end and a pen head fixed end. The pen head refill end is used to accommodate a refill, and the pen head fixed end is connected to the grip pen section 1 in a screw rotation mode or a pullable mode.
