Description

Wrist hooking corrector

Technical Field

The utility model relates to a writing posture correction tool, in particular to a collude wrist corrector.

Background

The wrist hooking is simply that the hand is hooked in during writing, the normal pen-conveying force-applying rule is violated during the wrist hooking writing, the writing is completed by dragging the pen holder with fingers, and the flexibility and the force control of the writing and the action are extremely poor. For example, when writing a horizontal line, the correct posture can be written by the easy swing of the wrist, the lifting and pressing actions in the writing process are easy to control, and the hooking of the wrist is realized by the translation of the hand.

Most of children write their wrists too far to the left or close to their body. The wrist hooking can cause wrist distortion, forward leaning of the body, reduction and insufficient unfolding of the movement space of fingers, reduction and distortion of writing and the like, the wrist hooking can cause a large fulcrum (the root of the palm of the wrist) to be pretty, the gravity center of the whole finger pen is forward leaning, the gravity center of the pen is transferred to the front end of the little finger, and the pen is written by the fulcrum, so that the pen holder is clamped by the thumb, the index finger and the middle finger tightly, and the pen is stiff and hard to transport. On the other hand, the big fulcrum of the hand is beautiful, no supporting point is available, the writing is unstable, and the user can not exert strength. Over time, the body leans forward and the sitting posture is incorrect, which may affect the development of the spine. In a few typical wrong pen-holding postures, the hooking of the wrist is the most serious problem in the pen-holding postures and must be corrected, otherwise, the pen is not opened, and the more characters are written, the smaller the characters are. Not only writing is not quick, but also hands can feel tired and ache. After a long time, the hand becomes tired after writing, the writing efficiency is low, and the hand skeleton development is caused to be problematic.

Detailed Description

The inner hook of the wrist is a wrong writing habit during writing, and the correction of the habit needs to start from two aspects of 'active' and 'passive'. The writing training mode described in the background art is actually an active correction method. For children with poor self-control ability, it is difficult to maintain active correction for a long time by self-awareness to correct the wrong habit. The passive mode means that the external force is used to stop the wrist from the error action of the inner hook during writing. The corrected person will typically reflect situations such as the corrected initial writing is not done, the writing is too slow, the writing is "unsightly," etc. In fact, it is not used to correct actions when it is used to wrong actions, but it is natural when it is used to correct actions by passive forced correction. The wrist limiting support body is fixed at the position from the palm to the forearm, and the wrist limiting support body is tightly attached to the wrist through the wrist strap, so that the wrist is limited from bending back during writing.

The invention will be further described with reference to the following examples, which are intended only for better understanding of the invention and therefore do not limit the scope of the invention.

In a first embodiment, as shown in fig. 1 to 4, the colluding wrist corrector provided in this embodiment includes a limiting support body 1 and a binding band 2, wherein the limiting support body 1 is composed of a limiting head 11 and a supporting portion 12, the supporting portion 12 is a straight rod body, and the supporting portion 12 is attached and fixed to the wrist vein position; the limiting head 11 extends to the palm position along the supporting part 12; the supporting part 12 is provided with a bandage 2, and the bandage 2 is fixed with the hand.

In this embodiment, the top of the limiting head 11 is circular. Avoid stabbing the hand. Further, the top of the limiting head 11 is also provided with a rubber body wrapping head.

In the second embodiment, as shown in fig. 5, in the wrist hooking corrector provided in this embodiment, the supporting portion 12 is a rigid straight rod, the limiting head 11 extends along the arc from the wrist to the palm, and the portion of the top of the limiting head 11 located at the palm is an arc 11-1.

With reference to fig. 6 and 7, further, the limiting head 11 of the present invention is an elastic structure, and the pressure of the portion of the limiting head 11 located at the palm of the hand, which is arched 11-1, to the palm of the hand increases gradually as the degree of the wrist hooking is larger.

In the present invention, the support portion 12 is a flat plate-shaped rod body; the limiting head 11 is a flat plate-shaped rod body or a round rod body.

The utility model discloses in, bandage 2 adopts the magic tape bandage. Preferably a strap with a resilient force.

At least one of the straps 2 is provided. The two bands 2 are preferably arranged, one band is tied to the wrist and the other band is tied to the forearm.

Specifically, the total length of the limiting support body 1 is about 20 cm. The wrist strap is about 25cm long, and the arm strap is about 30cm long. The wrist strap and the arm strap are made of back-to-back magic tapes, one end of the bandage is provided with a lantern ring, and the limiting supporting body is tightly hooped in the lantern ring.

When in use, the limiting head of the limiting support body 1 is arranged at the palm center, and the position is suitable for holding the limiting head 11 when the palm is virtual. The wrist strap is adjusted to the cross grain of the wrist, the wrist strap is wound and adhered tightly around the wrist, the soft hair of the magic tape is adhered to the skin, the winding tightness is based on the wrist tightly adhered by the supporting part 12 (as shown in figures 3 and 5), and the arm strap is wound and adhered tightly. At this time, the position restricting support 1 is closely attached from the palm to the wrist to the forearm.

When writing, the movement range of the wrist is limited, the wrist can be lifted upwards, but the wrist can only be moved downwards to a flat position, and if the wrist is pushed downwards again, the wrist is collided by the limiting head 11, and the inward hooking action cannot be performed. When the corrector is worn during writing, the writing feels slow and awkward at the beginning, and the feelings disappear after the user is used. After the wrist-writing posture corrector is worn for a period of time, the writing posture is corrected, and the wrist-writing posture corrector can be separated from the correct wrist-writing posture.

The above description is only a preferred and practical embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent variations made by using the contents of the specification and the drawings are included in the scope of the present invention.
