During use, the anti-wrist-hooking member 2 extends from the palm of the user to the wrist or forearm, forming a certain degree of physical limitation between the palm and the wrist or forearm, thereby restricting the palm from bending towards the user's chest direction during writing.
[0038] By passing the pen shaft through the pen-holding member 1 or abutting against the pen-holding member 1, and connecting the pen-holding member 1 by the anti-wrist-hooking member 2, the inward hooking of the wrist is restricted, so that this correction device can be directly picked up and used without an additional fixing band to fix the anti-wrist-hooking plate, which is efficient and convenient. In this embodiment, taking the example where a perforation 111 is provided in the pen-holding member 1 and the anti-wrist-hooking member 2 bends and extends from the palm to the forearm for illustration.
[0039] Specifically, the pen-holding member 1 includes a pen-holding portion adapted to block the last three fingers from the palm, thereby correcting the pen-holding posture in a fist shape; a pen-receiving portion connecting the pen-holding portion, with a perforation 111 or an opening groove provided in the pen-receiving portion; and an anti-hook-wrist member 2 connected to one end of the pen-holding portion away from the pen-receiving portion. In this embodiment, the pen-receiving portion of the pen-holding member 1 is located at the top, and the perforation 111 penetrates through the pen-receiving portion. In some other embodiments, the pen-holding member 1 may only include the pen-receiving portion, and the anti-hook-wrist member 2 is connected to the pen-receiving portion.
[0040] Further, the pen-holding member 1 has a perforation 111 or an opening groove adapted for the pen shaft to pass through.
[0041] The perforation 111 or the opening groove is provided with a plurality of buffer teeth 112; the plurality of buffer teeth 112 are circumferentially distributed along the perforation 111 or the opening groove. By providing the plurality of buffer teeth 112, the inner diameter of the perforation 111 can be adjusted within a certain range, so as to be applicable to pen shafts of different diameters and increase the applicable range of the product. In this embodiment, the buffer teeth 112 are granular teeth, and preferably, buffer teeth 112 are provided at both ends of the perforation 111 and the opening groove. In some other embodiments, the buffer teeth 112 are strip-shaped teeth and are arranged along the length direction of the perforation 111 or the opening groove.
[0042] The pen-holding portion includes a soft shell 11 and a hard shell 12 spliced with the soft shell 11. At the front end of the hard shell 12, a closed cavity is formed by the soft shell 11, increasing the elasticity of the finger placement part; the hard shell 12 is located on the side of the soft shell 11 close to the palm; the anti-hook-wrist member 2 is rotatably connected to the hard shell 12. The soft shell 11 improves the grasping feel, and the hard connection is formed between the hard shell 12 and the anti-hook-wrist member 2 to further improve the anti-hook-wrist effect.
[0043] Further, the hard shell 12 is provided with a pen-passing through hole 1212; the pen-receiving portion is provided on the soft shell 11; the pen-passing through hole 1212 is communicated with the perforation 111, or the pen-passing through groove is communicated with the opening groove. In this embodiment, after the part of the hard shell 12 having the pen-passing through hole 1212 penetrates into the soft shell 11, it is communicated with the perforation 111, so as to form a hard connection path among the pen shaft, the hard shell 12, and the anti-hook-wrist member 2, further improving the limiting effect on hook-wrist.
[0044] The hard shell 12 includes a bottom plate 121 and a panel 122, and a receiving space is formed between the two. A column groove, a buckle plate for connecting the two, and a space for connecting with the anti-hook-wrist member 2 are provided in the receiving space. The soft shell 11 is connected to the front end of the bottom plate 121, that is, the end facing away from the panel 122, and the above-mentioned pen-passing through hole 1212 is provided on the bottom plate 121; the panel 122 has a curved surface convexity facing the palm direction and is adapted to fit with the palm; a connecting groove 14 is provided at the lower end of the hard shell 12, on the side close to the user's chest, to provide a space for installing and moving the anti-hook-wrist member 2 through the connecting groove 14.
[0045] In this embodiment, the anti-hooking wrist member 2 as a whole presents a curved plate shape that fits along the bends of the palm, wrist, and forearm in sequence. On the bottom plate 121, at the position corresponding to the connecting groove 14, a rotating shaft 1211 is provided. One end of the anti-hooking wrist member 2 is sleeved outside the rotating shaft 1211, and the anti-hooking wrist member 2 is fixed to the rotating shaft 1211 by screws.
[0046] Preferably, the rotation direction of the anti-hooking wrist member 2 is set parallel or nearly parallel to the plane that fits the wrist. One of the purposes of this setting is to adjust the angle between the anti-hooking wrist member 2 and the pen-holding member 1 by rotating the anti-hooking wrist member 2, so as to adapt to hands of different sizes, or adjust the position of the end of the anti-hooking wrist member 2 between the inner and outer sides of the forearm to adapt to the usage preferences of different users. Ultimately, it can increase the applicability of the product and enhance the user's willingness to use. In some other embodiments, the rotation direction of the anti-hooking wrist member 2 is set perpendicular to the fitting surface of the wrist, that is, in the same plane as the incorrect wrist-hooking writing posture, and the rotation range is limited to an angle opposite to the wrist-hooking. Thus, when the anti-hooking wrist member 2 and the pen-holding member 1 are unfolded, it can be used for correcting the wrist-hooking pen-holding posture, and when contracted, it is convenient for storing the entire device.
[0047] Furthermore, a gear mechanism is further included and is disposed between the pen-holding member 1 and the anti-hooking wrist member 2; the gear mechanism includes a positioning portion 13 and a gear portion 21 with several gears; the gear portion 21 is connected to one of the pen-holding member 1 and the anti-hooking wrist member 2, and the positioning portion 13 is connected to the remaining one of the pen-holding member 1 and the anti-hooking wrist member 2. By rotating the anti-hooking wrist member 2, the positioning portion 13 can be engaged into different gears, so as to maintain the relative position and angle between the pen-holding member 1 and the anti-hooking wrist member 2, and avoid the anti-hooking wrist member 2 rotating due to the force of the hand during use, which may bring an adverse usage experience. In this embodiment, preferably, the gear portion 21 is disposed at one end of the anti-hooking wrist member 2 close to the pen-holding member 1, that is, at one end between the rotating shaft 1211 and the pen-holding member 1, and the positioning portion 13 is disposed at the corresponding position on the pen-holding member 1; in some other embodiments, the gear portion 21 can also be disposed at this end between the rotating shaft 1211 and the forearm.
[0048] The positioning portion 13 includes a positioning block 131 and an elastic member 132; the positioning block 131 is movably connected to the pen-holding member 1 or the anti-hooking wrist member 2; the elastic member 132 is disposed between the positioning block 131 and the pen-holding member 1 or the anti-hooking wrist member 2, and is adapted to keep the positioning block 131 engaged into the gear.
[0049] In this embodiment, the elastic member 132 is preferably a spring. The positioning block 131 is slidably arranged on the bottom plate 121 of the pen-holding member 1. The spring is arranged between the positioning block 131 and the bottom plate 121. A plurality of gears of the gear portion 21 are arranged side by side on the anti-hook-wrist member 2. The spring pushes the positioning block 131 towards the gear portion 21, so that the end of the positioning block 131 meshes with the gear of the gear portion 132, and the relative position between the anti-hook-wrist member 2 and the pen-holding member 1 is maintained. When an external force intervenes and the anti-hook-wrist member 2 is rotated to squeeze the positioning block 131 and overcome the spring force, the relative position between the anti-hook-wrist member 2 and the pen-holding member 1 can be adjusted. In addition, through the above settings, when adjusting the anti-hook-wrist member 2, the positioning portion 13 and the gear portion 21 can make a clicking sound, so that the user knows that there is an adjustment or provides feedback during the adjustment, thereby improving the user experience of the product.
[0050] In some other embodiments, the above-mentioned positioning portion 13 can be arranged on the anti-hook-wrist member 2, and the gear portion 21 can be arranged on the bottom plate 121; or the elastic member 132 of the positioning portion 13 can be replaced with a torsion spring or a spring sheet instead of a spring. In still other embodiments, the above-mentioned elastic member 132 can be integrated into the material elasticity, and through the deformation of the material itself, the different gears arranged on the anti-hook-wrist member 2 are directly squeezed through the positioning portion 13 and cooperate with the positioning portion 13.
[0051] Further, a damping member 3 is further included, which is arranged between the pen-holding member 1 and the anti-hook-wrist member 2. When the anti-hook-wrist member 2 is rotated, it is adapted to provide rotational damping, improve the feel of adjustment, facilitate the user to position to a suitable position, avoid over-adjustment, and at the same time can improve the texture of the product.
[0052] A hook-wrist pen-holding correction device of the present utility model sets an anti-hook-wrist member on the pen-holding member. When in use, the pen shaft is inserted through the pen-holding member, and the anti-hook-wrist member extends from the palm of the hand to the wrist or forearm, forming a physical limit to restrict the inward bending of the wrist, so as to achieve the purpose of correcting hook-wrist writing. In addition, this correction device can be directly picked up and used without an additional fixing band to fix the anti-hook-wrist plate, which is efficient and convenient.
[0053] The above embodiments only represent some implementation manners of the present invention. Without departing from the concept of the present invention, several deformations, substitutions and improvements made by those skilled in the art without creative labor all belong to the protection scope of the present invention.
