Description

Technical Field

[0001] The invention relates to the field of stationery, in particular to a pen holder for a posture correction pen and a posture correction pen. Background Art

[0002] When people write with a pen, they feel tired when holding a common pen under the pressure of the pen shaft. What's worse, long-term writing will cause the fingers to deform. At the same time, there is no fixed way to hold the pen and write. The weight of the pen varies. If it is heavy, the paper will be scratched, and if it is light, the handwriting will be blurred. Especially for children who are just starting to learn to write, if they do not correct their pen holding posture and sitting posture during the practice, once they develop bad writing habits, they will not be able to correct them later, and bad writing habits will also lead to poor writing results.

[0003] In order to correct children's pen-holding posture, some corrective pens have appeared on the market, trying to help children write in the correct posture. Most of the corrective pens in the prior art correct children's pen-holding posture by three-point positioning, that is, the pen-holding posture is corrected by the thumb, index finger and middle finger. Most of the prior art designs the pen holder at the positions of these three points with a concave surface, so that the thumb, index finger and middle finger are naturally held in the correct position. However, even if these three positions are held correctly, the position where the other end of the pen holder contacts the hand is prone to deviation. The correct contact position should be the end of the index finger bone joint, and many people tend to put the pen holder against the tiger's mouth, still forming a bad posture. In addition, the correct pen-holding posture is that the index finger is slightly lower than the middle finger, and in the conventional three-point positioning design, the height of the three contacts is the same, resulting in the index finger and the middle finger being the same height when holding the pen, forming a bad pen-holding posture, and the height of the three contact surfaces is the same, resulting in it being difficult to find the correct pen-holding position at one time, which is inconvenient to use.

[0004] In addition, children who are just beginning to learn to write usually want to know what their handwriting will look like. When they don't master the correct posture, the pen tip is blocked by the hand holding the pen or the pen shaft, so they tilt their heads and hook their hands to confirm the pen placement, resulting in incorrect writing posture. Summary of the invention

[0005] The purpose of the present invention is to provide a pen holder and a posture correction pen which can effectively correct the pen holding posture and are easy to use.

[0006] In an embodiment of the present invention, a pen body of a posture correction pen is provided, which includes a pen head, a pen tail and a grip portion located between the pen head and the pen tail, wherein the end of the grip portion close to the pen head is provided with a thumb grip surface, an index finger grip surface and a middle finger rest surface which are separated by two longitudinal ridges and are recessed inwardly, and the end of the grip portion close to the pen tail is provided with an index finger root rest structure which is curled and protruded outwardly.

[0020] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] The implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, in an embodiment of the present invention, a posture correction pen is provided, which includes a pen holder and a refill disposed in the pen holder. The pen holder includes a pen head 1, a pen tail 2, and a grip portion 3 located between the pen head 1 and the pen tail 2. The grip portion 3 is provided with a thumb grip surface 32, an index finger grip surface 33, and a middle finger rest surface 34 separated by two longitudinal ridges 31 and recessed inwardly at one end thereof, at one end thereof, at the pen tail 2. The grip portion 3 is provided with an index finger root rest structure 35 that curls and bulges outwardly at one end thereof, at one end thereof, at the pen tail 2.

[0023] It should be noted that the direction of the longitudinal ridge 31 is consistent with the length direction of the pen shaft, and it can be a regular shape or an irregular shape, which is used to separate the thumb gripping surface 32, the index finger gripping surface 33 and the middle finger resting surface 34. The thumb gripping surface 32, the index finger gripping surface 33 and the middle finger resting surface 34 are all concave curved surfaces, which are respectively used to position the thumb, index finger and middle finger holding the pen. The concave shapes of the thumb gripping surface 32, the index finger gripping surface 33 and the middle finger resting surface 34 are consistent with the thumb, index finger and middle finger, thereby ensuring the correct pen holding posture. In the standard pen holding posture, the lowest point of the thumb pulp should be higher than the lowest point of the middle finger pulp. Therefore, in the embodiment of the present invention, the lowest point of the thumb gripping surface 32 is higher than the lowest point of the index finger gripping surface 33. Compared with the structure in the prior art in which the thumb gripping surface and the index finger gripping surface are the same, such a design can better ensure the correct pen holding posture and facilitate the identification of the correct holding position.

[0024] It should be noted that the posture correction pen of the embodiment of the present invention can be an automatic pencil, an ordinary pencil, or a ballpoint pen, and the present invention is not limited to this. The grip portion 3 can be integrally formed with the pen tip 1 and the pen tail 2 using the same material, or can be a separate component that is assembled and connected with the pen tip 1 and the pen tail 2 through a thread, and the present invention is not limited to this.

[0025] In the correct pen-holding posture, the tail of the pen should rest on the index finger heel joint, not the base of the thumb. Therefore, in the embodiment of the present invention, the index finger resting structure 35 is a curved surface that curls outward at the edge of the grip 3 and fits the index finger heel joint. Its function is to serve as the fourth positioning point of the pen holder of the posture correction pen, and to position the posture correction pen to ensure the user's correct pen-holding posture. After the user holds the pen, the index finger resting structure 35 naturally fits the index finger heel joint, so that the user can naturally maintain the correct pen-holding posture.

[0026] Due to the different lengths of the hand bones of young children and older children, it is difficult to ensure that the index finger resting structure 35 can be in the correct position. Therefore, in the embodiment of the present invention, two specifications of pen barrels, long and short, are designed for the index finger resting structure 35 according to the different ages of the users. In the short specification, the distance from the outlet of the pen core of the pen tip 1 to the vertex of the index finger root resting structure 35 is 71mm, which is suitable for children with a hand length less than 135mm, generally students under 7 years old. The short version can make it easier for small hands to feel the correct position and pen holding height of the index finger resting structure 35, and the fourth point positioning effectiveness is better. In the long specification, the distance from the outlet of the pen core of the pen tip 1 to the vertex of the index finger root resting structure 35 is 86mm, which is suitable for children with a hand length greater than 135mm, generally students over 7 years old. The short version is for younger children who are unfamiliar with pen grip and have lower pen control ability, so the grip part needs to be thicker and the posture correction depression is deeper. The long version is for students who are more familiar with pen grip, so the posture correction depression is deeper, the grip restriction is lower, and writing is more comfortable.

[0027] Furthermore, in the embodiment of the present invention, a pen tip 11 is provided at the outlet of the refill of the pen head 1, and the pen tip 11 deviates from the central axis of the pen shaft and deviates in a direction away from the middle finger resting surface 34. In the prior art correct posture pens, the pen tip is set on the central axis of the pen shaft. This structure may cause the pen tip to be blocked by the grip of the pen shaft when writing, causing the user to put their head in an incorrect posture in order to see the pen tip. In the implementation of the present invention, the pen tip 11 deviates from the central axis of the pen shaft and deviates in a direction away from the middle finger resting surface 34, which can reduce the obstruction of the pen tip 11 by the grip 32 when writing.

[0028] Furthermore, in the embodiment of the present invention, a soft rubber strip is provided on the middle finger resting surface 34. Since the position of the middle finger resting surface and the middle finger is movable during writing, many children tend to wear out the corresponding position of the middle finger when writing too much with a pen, causing pain or calluses. To prevent this problem, in the embodiment of the present invention, a soft rubber strip is provided on the middle finger resting surface 34, which can effectively protect the middle finger and prevent discomfort caused by wear.

[0029] Furthermore, in an embodiment of the present invention, a height limit color ring 4 is provided at the connection between the grip portion 3 and the pen head 1. The height limit color ring 4 is used to mark the lowest position of holding the pen, which can effectively prevent the pen from being held too low. The color of the height limit color ring should be clearly distinguished from the color of the pen barrel, so as to achieve a clear identification effect. In an embodiment of the present invention, the pen tail 2 is also provided with an anti-roll bar 21. The anti-roll bar 21 is used to prevent the correct posture pen from rolling.

[0030] To summarize, the end of the holding portion of the pen shaft of the correct posture pen of the present invention close to the pen head is provided with a thumb holding surface, an index finger holding surface and a middle finger resting surface separated by a longitudinal ridge and recessed inwardly, and the end of the holding portion close to the pen tail is provided with an index finger root resting structure that curls and bulges outwardly, and through a four-point positioning method, it can ensure that children are in the correct pen-holding posture; the pen tip deviates from the central axis of the pen shaft and deviates in the direction away from the middle finger resting surface, and adopts an eccentric pen tip structure, so as to prevent the holding part from blocking the pen tip and reduce the possibility of children tilting their heads and hooking their hands when writing; a height limiting color ring is provided at the connection between the holding portion and the pen head, which can prevent the pen from being held too low and causing incorrect pen holding posture.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
