Description

Technical Field

[0001] The present invention relates to the technical field of a figure-9 pen-holding posture and a pen-holding posture assistant, and in particular to a figure-9 pen-holding posture and a pen-holding posture assistant. Background Art

[0002] Hooked wrists when writing refers to the incorrect posture habit of young children when they are writing, in which their palms are bent inwards of the wrists. Hooked wrists will cause children to write ugly and slow, affecting the writing effect. It is also difficult to correct and will have an adverse effect on their physical development over time.

[0003] In order to solve this problem, there are some devices in the prior art to prevent wrist hooking, but most of them are set on the inner side of the arm and palm. Since the palm is closed when writing, this kind of device will produce hard squeezing on the palm when used, which brings obvious discomfort or even pain, and also affects the pen holding and writing. There are also some devices set on the back of the hand, such as CN214475722U, a wrist hook corrector, in which a bending section is set on the front side of the support plate, and the bending angle of the bending section fits the correct posture of the hand when writing. The support plate is set on the back of the hand and arm, and is bound by a strap to support and fix the wrist posture, so as to always maintain the correct writing posture; with the guard plate, the corrector is U-shaped as a whole, which can prevent the support plate from shifting during use and requiring constant adjustment, and is more convenient to use.

[0004] However, this solution still has the following shortcomings:

[0005] 1. The bending angle of the support board is fixed and cannot be adjusted. It is inflexible to use and difficult to adapt to different hand shapes and meet the continuous use of children during their growth.

[0006] 2. The overall shape of the corrector is U-shaped, with a long hard pad at the bottom of the arm, which makes the arm placement very unnatural. This results in a big difference in the feeling when using it compared to normal writing, and is not easily accepted by children.

[0007] 3. Use a strap to tie your palm from the base of your thumb, which makes your palm feel unnatural and uncomfortable when holding a pen to write, and also affects your ability to hold a pen and write. Summary of the invention

[0042] The present embodiment provides a 9-shaped pen-holding posture and a pen-holding posture aid, comprising a hand back plate 1 and an arm plate 2 pivotally connected and rotating, a fixed clamping seat 3 is provided on the upper part of the hand back plate 1, the clamping seat 3 is in a rectangular shape, a movable push rod seat 4 is provided on the clamping seat 3, a knob bolt 5 is provided on one side of the push rod seat 4, the knob bolt 5 is threadedly connected to the push rod seat 4, the knob bolt 5 is located on the outer side of the clamping seat 3 and can press the side surface thereof, and the knob bolt 5 fastens the push rod seat 4; a fixed thenar sleeve 6 is provided on the side of the hand back plate 1 facing the knob bolt 5; the thenar sleeve 6 is inserted from the thumb onto the thenar, and the thenar sleeve 6 is made of inelastic plastic cloth material;

[0043] A vertical fixed support plate 7 is provided on the upper part of the arm plate 2, and a fixed shaft 8 is provided on the top of the fixed support plate 7. The fixed shaft 8 is rotatably connected with the movable support rod 9. A ball head 10 is provided at the other end of the movable support rod 9. The ball head 10 has a diameter larger than that of the movable support rod 9. The ball head 10 is stuck in the square seat 3 and falls on the push rod seat 4. The bottom of the ball head 10 is naturally stuck on the push rod seat 4. The push rod seat 4 has baffles on both sides of the ball head 10. The ball head 10 is controlled to slide through the push rod seat 4. When the push rod seat 4 is pushed, the ball head 10 moves with it. A strap 11 is provided at the bottom of the arm plate 2. The strap 11 has two groups of intervals, which are used to tie the arm near the wrist.

[0044] The two inner sides of the clamping seat 3 are provided with arc grooves 12, and the ball head 10 is clamped and slides between the two arc grooves 12. The ball head 10 slides linearly along the arc grooves 12.

[0045] The pivot joint 13 between the back of hand plate 1 and the arm plate 2 rotates via a rotating shaft 14 .

[0046] The diameter of the pivot joint 13 is 2-5 cm. The larger the diameter of the pivot joint 13, the more comfortable it is to put on the wrist joint and the better it can adapt to different wrist joint widths.

[0047] The thenar sleeve 6 is fixedly connected to the back of the hand plate 1 through a cloth piece 15. The cloth piece 15 is made of inelastic plastic cloth.

[0048] The binding belt 11 is a self-adhesive binding belt. The binding belt 11 is an inelastic belt, and a Velcro is provided on the outside of one bonding end and a Velcro is provided on the inside of the other bonding end, so that the binding belt 11 can be adhered to each other.

[0049] Long holes 16 are provided on both sides of the clamping seat 3 , and the push rod seat 4 passes through the two long holes 16 and can slide along the long holes 16 .

[0050] The front end of the thenar sleeve 6 is provided with a leather ring 17, which is an elastic thin ring sheet of a certain width. The leather ring 17 is sleeved on the root of the thumb, which is conducive to stabilizing the thenar sleeve 6.

[0051] In the specific implementation, an adult assists in the operation of wearing, first inserts the thumb into the leather ring 17 to put on the thenar sleeve 6, then puts the back of the hand plate 1 naturally on the back of the hand, rotates the arm plate 2 (the knob bolt 5 is not tightened in advance) and puts it on the upper part of the arm behind the wrist (the push rod seat 4 and the ball head 10 slide together in the holder 3 during the rotation), the pivoting rotation joint 13 falls on the wrist joint, and then the arm is tied with the strap 11, and the wearing of the device is completed. Adjust the wrist to the correct posture without hooking the wrist, then turn the knob bolt 5 to press the holder 3, so that the push rod seat 4 is fixed, so that the ball head 10 is also fixed, and at the same time, the angle between the fixed support plate 7 and the movable support rod 9 is fixed, so that the angle between the back of the hand plate 1 and the arm plate 2 is fixed, and at the same time, the angle between the hand and the arm is fixed to avoid hooking the wrist, and then you can hold a pen and practice calligraphy.

[0052] Practice writing with the figure-9 pen-holding posture:

[0053] This auxiliary tool has a yellow rectangular main body, 70mm long and 50mm wide, and the main body thickness towards the writing surface is about 8mm; an orange approximately triangular three-dimensional part is exposed above the yellow rectangular main body, with a thickness of about 2mm. (The right side of the approximately triangular three-dimensional part is connected to the right side of the yellow rectangular main body, and the line segment is 5mm long).

[0054] The upper right corner is a small arc (blue line) plus a small line segment (green line), where the line segment is tangent to the arc and is horizontal. On this basis, it can be expanded upward to a roughly circle, forming an Arabic numeral "9" shape with the vertical line on the right edge of the tool (where the right side of the "9" shape is the vertical line shape of daily writing, not the hook shape of the electronic version of 9). For the convenience of actual writing and visual convenience, only the small arc and line segment are left. On the right edge of the auxiliary tool, three positioning points are marked, which are the card positions of the middle finger, ring finger, and little finger on the right side of the tool from top to bottom. The upper middle part of the right side of the auxiliary tool is a quarter circle, and it is a three-dimensional groove, hollowed out 3mm in the depth direction of the writing surface.

[0055] The core idea is that when writing, except for the thumb, the fingertips of the last four fingers of the right hand need to be connected in a straight line pointing directly in front of the body to achieve the correct writing posture (9-shaped pen holding posture) and prevent the phenomenon of hooking the wrist and hooking the hand. Specifically, before writing, the fingertips of the middle finger, ring finger, and little finger of the right hand need to be fixed on the three card points from top to bottom on the right side of the tool, so that the fingertips of these three fingers are stuck on the right edge of the tool and point directly in front of the body. When writing, the fingertip of the index finger also needs to be connected in a straight line to achieve a straight line of four fingertips pointing directly in front of the body. When writing, write in the circle above the "9" shape, and the height of the index finger is the same as the height of the circle to achieve the 9-shaped pen holding posture.

[0056] The present invention and its embodiments are described above, and such description is not restrictive, and the actual protection scope is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
