Description

Technical Field

[0001] This utility model relates to the field of stationery products, and in particular to a pen grip posture corrector. Background Technology

[0002] A pen grip posture corrector is an assistive tool specifically designed to improve incorrect pen grip posture. Pen grip posture correctors are generally fitted onto the pencil barrel and help users (especially children) develop correct pen grip habits by guiding or restricting the relative position between the fingers and the pencil.

[0003] Most pen grip posture correctors on the market currently have finger grooves on the outer periphery for the thumb, index finger, and middle finger, as shown in Chinese utility model patents CN202986460U and CN201693890U. However, the diameter of the insertion hole in these correctors is usually smaller than the outer diameter of the pencil. This design increases the difficulty of inserting the pencil. Furthermore, inserting the pencil can deform the corrector, causing the finger grooves to deform as well, thus affecting the correction effect. Additionally, since the corrector relies on its own elastic deformation to securely fit the pencil, the pencil can still write normally even if the user's three fingers are not correctly positioned in the corresponding grooves, making it difficult to ensure that the user's three fingers are in the correct position, resulting in poor pen grip posture correction.

[0004] To address the aforementioned issues, the diameter of the insertion hole in the pen grip posture corrector is set to be slightly larger than the maximum outer diameter of the pencil. Simultaneously, a protrusion is provided on the inner wall corresponding to the finger groove, contacting the pencil shaft. The inner diameter enclosed by these protrusions is exactly equal to the maximum outer diameter of the pencil. During use, the pen grip posture corrector and pencil will not move relative to each other only when the user places their fingers in the correct finger groove and applies force, ensuring normal pencil use. Otherwise, if the fingers are not placed in the correct finger groove, it is difficult to grip the pencil firmly. As a result, when writing, the pencil will move upwards relative to the pen grip posture corrector due to the reaction force from the paper, meaning the pencil will retract into the corrector and become unusable. This design ensures that the user must place their fingers in the correct finger groove, thus achieving a more effective correction. Because ordinary pencils are cylindrical or hexagonal prisms, and cylindrical pencils have a uniform diameter, the aforementioned inner wall protrusions fit snugly against the outer wall of the cylindrical pencil. Even when the user's hand is not firmly gripping the pencil posture corrector, the pencil will not easily slip out of the corrector due to its own weight. However, when the pencil is hexagonal, the distance between two opposite sides is less than the distance between two opposite edges. The inner diameter enclosed by the multiple protrusions on the inner wall is exactly equal to the distance between two opposite edges. When the pencil posture corrector is used on this type of pencil, if the protrusions on the inner wall are directly opposite the side of the pencil, there is a gap between the protrusions and the side, meaning the protrusions cannot fit snugly against the side of the pencil. Therefore, even when the user's hand is not firmly gripping the corrector, the pencil will easily slip out of the corrector due to its own weight. This requires the user to frequently re-insert the pencil into the corrector, affecting its ease of use.

[0005] Therefore, it is necessary to provide a technical solution to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to design a pen grip corrector that can effectively correct the user's pen grip posture and prevent the pencil from easily slipping out of the pen.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A pen grip posture corrector includes a hollow body with a channel for inserting a pen through it; the outer wall of the hollow body is provided with a plurality of finger placement portions, and the inner wall of the hollow body is provided with a plurality of first protrusions, each finger placement portion being arranged opposite to at least one first protrusion; the inner wall of the hollow body is also provided with at least one second protrusion, the projection of the second protrusion in the vertical direction being at least partially located between the projections of two adjacent first protrusions in the vertical direction.

[0009] Furthermore, at least one of the second protrusions includes at least one annular protrusion, at least one vertical straight protrusion, at least one spiral curve protrusion, at least one dot protrusion, or at least one block protrusion.

[0010] Furthermore, at least one of the second protrusions includes a plurality of annular protrusions, which are spaced apart along the axial direction of the hollow body on the inner wall of the hollow body.

[0011] Furthermore, at least one of the second protrusions includes a plurality of vertical straight protrusions, which are spaced apart circumferentially on the inner wall of the hollow body.

[0012] Furthermore, at least one of the second protrusions also includes a plurality of annular protrusions, which are spaced apart along the axial direction of the hollow body on the inner wall of the hollow body.

[0013] Furthermore, at least one of the second protrusions includes a plurality of spiral curve protrusions, which are spaced apart circumferentially on the inner wall of the hollow body.

[0014] Furthermore, at least one of the second protrusions also includes a plurality of annular protrusions, which are spaced apart along the axial direction of the hollow body on the inner wall of the hollow body.

[0015] Furthermore, there are three finger placement portions: a thumb placement portion, an index finger placement portion, and a middle finger placement portion.

[0016] Furthermore, all three finger placement portions are recessed grooves that are recessed inward relative to the outer surface of the hollow body, and when viewed from the pen tip toward the pen barrel, the middle finger placement portion, the index finger placement portion, and the thumb placement portion are arranged in a clockwise spiral upward sequence.

[0017] Furthermore, the pen grip posture corrector also includes an index finger root positioning block, which is located at the top of the hollow body. The index finger root positioning block is provided with an insertion hole communicating with the channel. The index finger root positioning block is inclined relative to the central axis of the hollow body toward the area between the thumb placement part and the index finger placement part.

[0018] The beneficial effects of this utility model are as follows: While ensuring that the pen grip posture corrector can effectively correct the user's pen grip posture, by providing at least one second protrusion on the inner wall of the pen grip posture corrector, and the projection of the second protrusion in the vertical direction is at least partially located between the projections of two adjacent first protrusions in the vertical direction, so that when the inserted pencil is hexagonal prism, no matter how the pencil is placed, at least one of the first protrusion or the second protrusion can form a close contact with the side edge of the pencil barrel. When the user does not hold the pen grip posture corrector tightly, the pencil will not easily slip off the pen grip posture corrector under its own weight, avoiding the problem of pencils frequently slipping off and causing inconvenience in use.

Detailed Implementation

[0029] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0030] like Figures 1 to 8 As shown, this utility model provides a pen grip posture corrector, which includes a hollow body 1, through which a channel 11 for inserting a pen is provided; the outer wall of the hollow body 1 is provided with a plurality of finger placement portions 2, and the inner wall of the hollow body 1 is provided with a plurality of first protrusions 3, each finger placement portion 2 being arranged opposite to at least one first protrusion 3; the inner wall of the hollow body 1 is also provided with at least one second protrusion, the projection of the second protrusion in the vertical direction being at least partially located between the projections of two adjacent first protrusions 3 in the vertical direction. Specifically, the channel 11 is cylindrical, and the inner diameter of the channel 11 is slightly larger than the maximum outer diameter of the pencil. The inner diameter of the space enclosed by the top surface of the first protrusion 3 and the second protrusion (the surface close to the central axis X of the channel 11) is equal to the maximum outer diameter of the pencil. A first protrusion 3 is provided on the inner wall of the hollow body 1 corresponding to the position of each finger placement part 2. The first protrusion 3 and the corresponding finger placement part 2 are arranged opposite to each other. The first protrusion 3 is a protrusion block.

[0031] In actual use, the user inserts the pencil 7 into the channel 11 of the hollow body 1, and places multiple fingers on the finger placement parts 2. When the user applies force with their fingers, the first protrusion 3, which is arranged opposite to the finger placement parts 2, contacts and squeezes the pencil, thus preventing relative movement between the pen grip posture corrector and the pencil 7 during writing and ensuring normal use of the pencil. If the fingers are not placed in the correct finger grooves, the force applied by the fingers to the pen grip posture corrector does not act on the first protrusion 3, making it difficult for the first protrusion 3 to squeeze the pencil. This makes it difficult for the user to grip the pencil 7 tightly. As a result, the pencil 7 will move upward relative to the pen grip posture corrector under the reaction force of the paper, meaning the pencil 7 will retract into the pen grip posture corrector and cannot be used normally. Therefore, the pen grip posture corrector in this embodiment can ensure that the user must place their fingers on the correct finger placement parts 2, thereby ensuring that the pen grip posture corrector has a better corrective effect. Based on this, the pen grip posture corrector in this embodiment is further provided with at least one second protrusion on the inner wall, and the projection of the second protrusion in the vertical direction is at least partially located between the projections of two adjacent first protrusions 3 in the vertical direction. This arrangement ensures that when the inserted pencil is hexagonal prism, and the first protrusion 3 is opposite to the side of the hexagonal prism, that is, when there is a gap between the first protrusion 3 and the opposite side, the second protrusion located between the adjacent first protrusions 3 will be opposite to the side edge of the pencil 7. Since the distance between the two opposite side edges of the pencil 7 is relatively large, the second protrusion will be in close contact with the side edge. When the hand is not gripping the pen grip posture corrector tightly, the pencil will not easily slip out of the pen grip posture corrector under its own weight, thus avoiding the problem of the pencil frequently slipping out and causing inconvenience in use.

[0032] It should be noted that in this utility model, the vertical direction is defined by the pencil tip pointing downwards and the pencil barrel being in an upright position. Figure 8 As shown, when the penholder's posture changes, the positional relationship between the components also changes.

[0033] It should be noted that the finger placement part 2 and at least one first protrusion 3 being arranged in an inner-outer opposite manner means that at least a portion of the finger placement part 2 and at least a portion of the first protrusion 3 are aligned in the inner-outer direction, including but not limited to the case where the finger placement part 2 and the first protrusion 3 have the same shape and size and are completely aligned, as long as the first protrusion 3 can squeeze the pen barrel when the user applies force to the finger placement part 2.

[0034] Furthermore, at least one of the second protrusions includes one or more of the following: at least one annular protrusion 51, at least one vertical straight protrusion 52, at least one spiral curve protrusion 53, at least one dot-shaped protrusion, or at least one block-shaped protrusion.

[0035] It should be noted that there can be one or more second protrusions, as long as they can ensure that the pencil will not easily slip off the pen grip posture corrector under its own weight when the user's hand is not gripping the corrector tightly. In this embodiment, there are multiple second protrusions, and the shapes of the multiple second protrusions can be the same or different from each other.

[0036] Furthermore, such as Figure 1-2 As shown in Figure 8, there are three finger placement parts 2, namely a thumb placement part 21, an index finger placement part 22, and a middle finger placement part 23. All three finger placement parts 2 are recessed inward relative to the outer surface of the hollow body 1, and the outline of the three recesses is an inclined irregular ellipse to adapt to the shape of the finger contacting the pen grip posture corrector. And looking from the pen tip to the pen barrel, the middle finger placement part 23, the index finger placement part 22, and the thumb placement part 21 are arranged in a clockwise spiral upward sequence to adapt to the placement position of the middle finger, index finger, and thumb.

[0037] Furthermore, such as Figure 3 As shown, at least one of the second protrusions includes a plurality of annular protrusions 51, which are spaced apart along the axial direction of the hollow body 1 on the inner wall of the hollow body 1. Specifically, there are two annular protrusions 51, which are located at the upper and lower ends of the inner wall of the hollow body 1. In this embodiment, by providing the annular protrusions 51, the hexagonal prism-shaped pencil 7 can be in close contact with the side edge of the pen grip posture corrector, whether the side of the pencil is opposite to the first protrusion 3 or the side edge is opposite to the first protrusion 3, effectively avoiding the problem of the pencil frequently slipping and causing inconvenience in use.

[0038] Furthermore, such as Figure 4 As shown, at least one of the second protrusions includes a plurality of vertical straight protrusions 52, which are spaced apart circumferentially on the inner wall of the hollow body 1. Specifically, there are three vertical straight protrusions 52, which are respectively disposed between adjacent first protrusions 3. In this embodiment, by providing vertical straight protrusions 52, when the side of the hexagonal prism pencil 7 is opposite to the first protrusion 3, the vertical straight protrusions 52 located between adjacent first protrusions 3 can fit in contact with the side edge, which can also effectively avoid the problem of the pencil frequently slipping and causing inconvenience in use.

[0039] Furthermore, such as Figure 5 As shown, at least one of the second protrusions includes not only multiple vertical straight protrusions 52, but also multiple annular protrusions 51. The multiple annular protrusions 51 are spaced apart along the axial direction of the hollow body 1 on the inner wall of the hollow body 1. Specifically, there are three vertical straight protrusions 52 and three annular protrusions 51. The three vertical straight protrusions 52 are respectively disposed between adjacent first protrusions 3, and the three annular protrusions 51 are respectively located at the upper end, middle part, and lower end of the inner wall. Through the synergistic effect of the annular protrusions 51 and the vertical straight protrusions 52, the problem of pencils frequently slipping and causing inconvenience in use can be more effectively avoided.

[0040] Furthermore, such as Figure 6 As shown, at least one of the second protrusions includes a plurality of spiral curve protrusions 53, which are spaced apart circumferentially on the inner wall of the hollow body 1. Specifically, there are three spiral curve protrusions 53, which spirally extend upwards from the bottom of the inner wall of the hollow body 1 to the top of the inner wall. In this embodiment, by providing spiral curve protrusions 53, it can be ensured that no matter how the hexagonal prism pencil 7 is placed in the pen grip posture corrector, the side edges of the hexagonal prism pencil 7 can be in close contact with the first protrusion 3 or the spiral curve protrusions 53 in the inner wall, which can also effectively avoid the problem of the pencil frequently slipping and causing inconvenience in use.

[0041] Furthermore, such as Figure 7 As shown, at least one of the second protrusions includes not only multiple spiral protrusions 53, but also multiple annular protrusions 51. The multiple annular protrusions 51 are spaced apart along the axial direction of the hollow body 1 on the inner wall of the hollow body 1. Specifically, there are three spiral protrusions 53 and two annular protrusions 51. The spiral protrusions 53 extend spirally upwards from the bottom of the inner wall of the hollow body 1 to the top of the inner wall, and the two annular protrusions 51 are located at the upper and lower ends of the inner wall, respectively. Through the synergistic effect of the annular protrusions 51 and the spiral protrusions 53, the problem of pencils frequently slipping and causing inconvenience can be more effectively avoided.

[0042] Furthermore, such as Figure 2As shown, the pen grip posture corrector also includes an index finger root positioning block 6, which is located at the top of the hollow body 1. The index finger root positioning block 6 is provided with an insertion hole 61 that communicates with the channel 11. The index finger root positioning block 6 is inclined relative to the central axis X of the hollow body 1 toward the area between the thumb placement part 21 and the index finger placement part 22. In this embodiment, when the user's thumb, index finger, and middle finger are placed on the correct finger placement part 2, the tilt angle of the index finger root positioning block 6 is perfectly matched to the shape of the index finger root position of the hand when holding a pen. When the user's thumb, index finger, and middle finger are not placed on the correct finger placement part 2, such as the thumb on the index finger placement part 22, the index finger on the middle finger placement part 23, and the middle finger on the thumb placement part 21, the tilt angle of the index finger root positioning block 6 does not match the shape of the index finger root position of the hand, causing discomfort at the user's index finger root position. Thus, in this embodiment, by setting the index finger root positioning block 6, the user's pen-holding posture is further ensured to be correct. Furthermore, the index finger root positioning block can be a 3D cartoon image, making the pen-holding posture corrector more aesthetically pleasing.

[0043] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
