Description

Pens with an adjustable grip

technical field

The invention relates to the field of writing tools, in particular to a writing tool with an adjustable holding structure.

Background technique

Pen tool is one of the greatest inventions in human history. It provides human beings with more convenient functions of writing or image recording, and enables human culture to be passed on smoothly. As far as pens are familiar to ordinary people, they are either hard pens such as fountain pens, ballpoint pens, and pencils, or soft pens such as brushes and watercolor pens. However, no matter what kind of pens, their purpose is the same, and they are also used for recording purposes. , the difference lies only in the method of holding it.

Please refer to Fig. 1 which is a schematic diagram of the holding posture of the existing pen tool. For the most common round pen holder a, the surface lacks the force point of the finger g, so when the user operates the pen tool, it is necessary to maintain the pen tool. Stable, in fact, grasp the round pen holder a in the way of "grabbing the pen" to write. In other words, finger g is exerting force anytime and anywhere. In the long run, it will inevitably cause finger g soreness, blisters and other finger injuries (area N1). Cause arm i injuries such as arm i soreness and fatigue (region M as shown in Figure 6). Especially for children, because the palm h is not yet fully developed, their finger g will gradually move down to the position of the nib b (as shown in Figure 2) due to the factor that they cannot firmly grasp the round pen holder a (as shown in Figure 2), not only writing is as stiff as carving , and because the small hands cover the line of sight, the children unknowingly write with their heads tilted or lying on their stomachs, which will cause vision and even spinal damage over time.

In addition, as shown in Figure 3, the industry also has a pen tool design with a triangular pen holder c that is different from the circular shape. The triangular pen holder c is used to speed up the positioning of the finger g, but the problem of "grabbing the pen" and its derivatives is still unavoidable. And this triangular pen holder c can be formed directly, or be covered with a soft triangular material rubber sleeve d outside the pen holder e. However, even if a thicker rubber sleeve d is used as shown in Figure 4, it still adopts the technique of "grasping" tight writing. Although the thicker rubber sleeve d will have a more soothing feeling in the initial stage of "grasping" tight writing, but in the After a short period of time, the finger g that is "grabbing" the writing force F will pass through the thicker rubber sleeve d and touch the hard pen holder e hidden at the bottom of the rubber sleeve d, thus still oppressing the finger g; , as shown in Figure 5, there is also a lower edge f of the thicker rubber sleeve d in an attempt to block the sliding of the finger g, so it is specially designed as a flange. After a period of time, his finger g and arm i are still sore and tired, which does not help to solve the problem.

In addition, for people with lesions in their fingers, such as those with incomplete fingers caused by injuries or lesions, or children whose fingers have not yet fully developed, the traditional method of holding a pen is obviously not applicable, and other methods must be adopted, and this can no longer be used. Such people have a heavy burden to avoid their fear of writing, thus affecting their daily routines.
