Description

Technical Field

[0001] The utility model relates to the technical field of pens, in particular to a right-posture triangular pen. Background Art

[0002] Pens are commonly used writing tools. Chinese Utility Model Patent Application No. CN03228580.9 proposes a triangular pencil characterized by an eraser holder at one end, comprising a hoop and an eraser head. This structure not only overcomes the drawback of the pencil being prone to rolling off the ground, but also offers a comfortable feel and ease of use.

[0003] However, existing triangular pens have some shortcomings that need improvement. Most existing learning pens use three grip surfaces. While this improves grip comfort compared to cylindrical pens, the pen diameter often becomes smaller, making it difficult to hold. After writing for a long time, the index finger can easily pinch the thumb. Pens with thicker overall thickness appear overly bulky, affecting writing flexibility. Furthermore, the three grip surfaces of existing pen holders are all the same size, failing to fully account for the wide thumb, resulting in an unreasonable pen-holding posture. Therefore, we have addressed this issue by proposing a triangular pen with a correct grip. Utility Model Content

[0004] The purpose of the present invention is to address the problems raised by the existing background technology. In order to achieve the above-mentioned purpose of the utility model, the present invention provides the following technical solutions: a straight-posture triangular pen, comprising a pen holder, wherein the lower portion of the pen holder has three gripping surfaces, the three gripping surfaces including a thumb gripping surface, a middle finger gripping surface, and an index finger gripping surface, the lower portion of the pen holder protrudes to one side, and the two gripping surfaces of the protruding portion are the thumb gripping surface and the middle finger gripping surface, and the thumb gripping surface and the middle finger gripping surface are larger than the index finger gripping surface.

[0005] As a preferred technical solution of the present invention, the two surfaces of the protruding portion, the thumb pen-holding surface and the middle finger pen-holding surface, are formed into isosceles triangles.

[0006] As a preferred technical solution of the present invention, the width of the thumb gripping surface is in the range of 6 mm to 7 mm.

[0007] As a preferred technical solution of the present invention, the width of the middle finger pen-gripping surface ranges from 5mm to 6mm.

[0008] As a preferred technical solution of the present invention, the width of the index finger pen-gripping surface ranges from 4 mm to 5 mm.

[0009] As a preferred technical solution of the present invention, a refill is provided inside the pen barrel, and a pressing rod is connected to the upper part of the refill.

[0010] As a preferred technical solution of the present invention, a telescopic spring is provided on the outside of the pen core.

[0011] As a preferred technical solution of the present invention, the total length of the pen barrel is 135mm-155mm.

[0012] Compared with the prior art, the present invention has the following advantages: By providing three gripping surfaces of different widths at the bottom of the pen barrel—thumb gripping surface, middle finger gripping surface, and index finger gripping surface—the present invention makes pen gripping more comfortable and natural. In particular, the thumb gripping surface and middle finger gripping surface are designed to be wider than the index finger gripping surface, better conforming to the natural curvature of the fingers and reducing finger fatigue during prolonged writing.

[0013] Traditional cylindrical pens can easily cause the index finger to pinch the thumb, especially when writing or drawing for extended periods. The Zhengzi Triangle Pen, however, effectively avoids this problem by increasing the gripping surface for the thumb and middle finger, improving user comfort.

[0014] The lower part of the pen barrel protrudes to one side, which not only increases the width of the pen grip surface, but also does not block the user's line of sight because it protrudes downward, thereby maintaining a good writing line of sight.

[0015] Compact and uncomplicated: Although the thumb and middle finger grips are larger, the index finger grip remains the same, so the pen remains relatively compact. This design ensures a comfortable grip while maintaining its lightness and portability.

[0016] The pen barrel is equipped with a refill, a pressing rod, and a telescopic spring. This structural design makes the pen smoother to use and facilitates the replacement of refills and maintenance.

[0017] The total length of the pen is controlled between 135mm and 155mm. This length range is suitable for most people's hands and can be used comfortably by both adults and children. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other. It should be noted that similar numbers and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0026] Example 1: Please refer to Figure 1 - Figure 4 A correct posture triangular pen comprises a pen holder 1, and the lower part of the pen holder 1 has three pen holding surfaces, which include a thumb pen holding surface 2, a middle finger pen holding surface 3, and an index finger pen holding surface 4. The lower part of the pen holder 1 protrudes to one side, and the two pen holding surfaces of the protruding part are the thumb pen holding surface 2 and the middle finger pen holding surface 3. The thumb pen holding surface 2 and the middle finger pen holding surface 3 are larger than the index finger pen holding surface 4.

[0027] The two surfaces of the protruding portion, the thumb grip surface 2 and the middle finger grip surface 3, are formed into isosceles triangles. The width of the thumb grip surface 2 ranges from 6mm to 7mm. The width of the middle finger grip surface 3 ranges from 5mm to 6mm. The width of the index finger grip surface 4 ranges from 4mm to 5mm.

[0028] As a preferred technical solution of the present invention, a refill 5 is provided inside the pen barrel 1, and a pressing rod 6 is connected to the upper part of the refill 5. A telescopic spring 7 is provided outside the refill 5. The total length of the pen barrel 1 is 135mm-155mm.

[0029] By providing three gripping surfaces of different widths on the lower portion of the pen barrel 1—thumb gripping surface 2, middle finger gripping surface 3, and index finger gripping surface 4—a more comfortable and natural pen grip is achieved. Specifically, the thumb gripping surface 2 and middle finger gripping surface 3 are designed to be wider than the index finger gripping surface 4, better conforming to the natural curvature of the fingers and reducing finger fatigue during prolonged writing.

[0030] The traditional cylindrical pen barrel 1 easily causes the index finger to pinch the thumb, especially when writing or drawing for a long time. The positive posture triangular pen effectively avoids this problem by increasing the grip surface of the thumb and middle finger, improving the comfort of use.

[0031] The lower part of the pen holder 1 protrudes to one side, which not only increases the width of the pen grip surface, but also does not block the user's sight because it protrudes downward, thereby maintaining a good writing sight.

[0032] Compact and non-bulky structure: Although the thumb and middle finger grip surfaces are enlarged, the index finger grip surface 4 does not increase in size, so the pen holder 1 does not become bulky. This design not only meets the requirements of comfortable grip surface, but also maintains the lightness and portability of the pen holder 1.

[0033] A refill 5, a pressing rod 6, and a telescopic spring 7 are provided inside the pen barrel 1. This structural design makes the pen easier to use and facilitates the replacement of the refill 5 and maintenance.

[0034] The total length of the pen barrel 1 is controlled between 135mm and 155mm. This length range is suitable for the hand shape of most people and can be used comfortably by both adults and children.

[0035] The three grip surfaces of different widths on the lower portion of the pen barrel 1 correspond to the thumb, middle finger, and index finger, respectively. Thumb grip surface 2 and middle finger grip surface 3 are wider, ranging from 6mm to 7mm and 5mm to 6mm, respectively, while index finger grip surface 4 is relatively narrow, ranging from 4mm to 5mm. This conforms to the natural curvature of the fingers. When the user holds the pen, the thumb and middle finger can better contact the wider grip surfaces, providing better support and stability, thereby reducing finger fatigue during prolonged writing.

[0036] Secondly, the lower portion of the pen barrel 1 bulges out to one side, with the two gripping surfaces of the bulge serving as thumb grip 2 and middle finger grip 3. This design increases the gripping area for the thumb and middle finger, effectively avoiding the problem of the index finger pinching the thumb that can occur with traditional cylindrical pen barrels 1, thus improving writing comfort. Furthermore, the downward bulge does not obstruct the user's vision, allowing the user to maintain a good line of sight while writing, ensuring accuracy and fluency.

[0037] The internal structure of the pen barrel 1 also plays an important role. A push rod 6 is connected to the top of the refill 5, and a telescopic spring 7 is located outside the refill 5. When the user presses the push rod 6, the telescopic spring 7 is compressed, extending the refill 5 and enabling writing. When the user releases the push rod 6, the telescopic spring 7 returns to its original position, retracting the refill 5 back into the pen barrel 1. This structural design makes the pen smoother to use and also facilitates replacement and maintenance of the refill 5.

[0038] Finally, the total length of the pen barrel 1 is controlled between 135mm and 155mm, which takes into account the hand size of most people. Whether adults or children, when using a pen of this length, they can hold the pen barrel 1 more comfortably and write, which improves the versatility and applicability of the pen.

[0039] The workflow steps of the positive triangle pen are as follows:

[0040] Preparation for holding the pen: When the user holds the pen holder 1, due to the downward convex structure of the pen holder 1, the convex side is facing downward, and the thumb and middle finger respectively hold the two sides of the convex part.

[0041] When users start writing or drawing, their fingers naturally bend and fit into their corresponding grip surfaces. The wider grip surfaces for the thumb and middle finger help reduce finger stress and fatigue.

[0042] The lower part of the pen barrel 1 protrudes to one side to ensure that the user's line of sight is not blocked, so that the user can maintain a good writing line of sight, which is particularly important for accurate writing.

[0043] After writing is completed, the user can press the rod 6 to shrink the pen core 5, thereby protecting the tip of the pen core 5.

[0044] Regularly check whether the telescopic spring 7 inside the pen barrel 1 is working properly to ensure that the pressing rod 6 can smoothly push out or retract the pen core 5. If the spring is found to be loose or damaged, it should be replaced in time to maintain the good performance of the pen.

[0045] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention are included in the scope of the claims of the present invention.
