Description

  The present invention relates to a writing aid that assists a person with muscle weakness and dysfunction of fingers with a natural writing sensation using a general-purpose writing instrument such as a pencil and a ballpoint pen.

Today, while input using information terminals such as personal computers, smart phones and ATMs can be seen in many scenes of daily life, there are also many scenes where handwriting writing to letters, diaries, application documents, etc. is required. Therefore, handwriting is an important factor that affects the quality of life (QOL) because it causes a heavy burden on people with hand muscle weakness and dysfunction. From the viewpoint of improving the QOL of people with such disabilities, various writing aids have been proposed to support handwriting.

  Patent Document 1 discloses, as a writing aid in the case where the gripping force of fingers is weak, attaching a dedicated fastener (attachment ring) to the writing instrument, hooking the belt to the fastener, and using this belt through palm and fingers It is done. Although this method requires an operation of holding the writing instrument by itself, the writing feel is natural and lightweight. However, there is a disadvantage that it takes time to fix the writing instrument to the hand and that the use of the writing instrument becomes difficult when it is difficult to hold the writing instrument by itself. In addition, fixing general-purpose writing instruments having different body widths has the disadvantage of requiring a dedicated fastener.

Patent Document 2 discloses a writing aid including a main body portion for inserting and fixing a writing tool into a communication hole and a carriage portion (slide means) provided on the main body portion, and gripping the main body portion as a grip There is. This auxiliary tool does not have to hold the writing tool directly because the grip of the main body is thick, and a stable operation is possible by the carriage having the rotating sphere at the bottom. Furthermore, the point where writing using a toe becomes possible is also excellent. However, there is a drawback that stable use is difficult when the force to grip the grip is weak by itself, and the use form is different from the natural writing sense. Moreover, in order to mount a general-purpose writing instrument having a different body width, an operation of inserting the writing instrument into the communication hole and fastening with a fixing screw is required.

Patent Document 3 discloses a gripping aid including a mounting portion to be mounted on a single finger and a pressing plate portion spaced apart from both long side surfaces of the mounting portion. This aid is excellent as an aid for supporting the grasping of the device for people with muscle weakness and dysfunction of fingers. However, it is mainly intended to stably attach a spoon, a fork, etc. to a finger, and it is difficult to use a general-purpose writing instrument having a different body width and use as a writing aid for performing a writing operation .

Patent Document 4 discloses a writing aid including a base having two openings into which an index finger and a middle finger of fingers are inserted, and a pen holder unit for fixing a pen. This auxiliary tool is light, it is not necessary to hold the auxiliary tool by itself, and it is excellent in that the method of use is a more natural writing form. However, the index finger and the middle finger are restrained by the base in order to prevent peristalsis of the aid during writing. For this reason, the control of the writing brush requires learning, and the details of the pen holder unit are not disclosed, and the pen holder unit illustrated has a disadvantage that the general-purpose writing instrument that can be used is limited.

The finger insertion portion 10 is bent downward near the center and has two openings for inserting fingers. Here, the finger insertion unit 10 includes the first support unit 13, the joint support unit 12, and the second support unit 11, fixes the index finger and the support tool, and places a load on fingers with functional impairments such as muscle weakness and paralysis It is for wearing without. If there is muscle weakness or dysfunction, the finger is bent inward at each joint (MP joint, PIP joint, DIP joint), and the entire finger is in an arc. Therefore, in order to facilitate insertion and removal of the index finger even when the finger draws an arc, it is preferable that the outer shape of the finger insertion portion 10 be bent downward near the center.

The material of the finger insertion portion 10 is not particularly limited as long as it has a strength enough to withstand the stress at the time of writing. Resin, metal, rubber, paper, ceramic and the like can be used.

The pair of butting parts 14 are arranged in a convex shape with a space between each of the long side faces of the finger insertion part 10 so as to be able to sandwich the writing instrument. In the example shown in FIG. 1 and FIG. 2, the butting portion 14 is formed as a pair of convex-shaped bulges continuous to each of both long side surfaces of the finger insertion portion 10. According to the present invention, the finger insertion portion 10 has a pair of abutment portions 14 at each of both long side surfaces at a distance wider than the body width of the writing instrument, and the finger insertion portion 10 faces the both long side surfaces , The pressing part 20 is bent upward in the vicinity of the center, and the pressing part 20 has a hook 21 for fixing the writing tool to the front inner surface, so that a general-purpose writing tool with different body width can be easily By finding that it becomes possible to wear.

The shape of the band-like pressing portion 20 is preferably bent upward near the center as shown in FIG. This makes it easy to insert the writing instrument into the aid. This is because the finger insertion portion 10 bent downward near the center and the pressing portion 20 bent upward near the center form a large opening for inserting the writing instrument.

FIG. 3 is an explanatory view showing an example of the writing aid according to the present invention, in which the writing tool is attached. The plan view shows how the writing instrument is attached to the right side of the assisting tool (in the case of left-handed), and the side view shows that the writing instrument is attached on the left side of the assisting instrument (in the case of right-handed). By lengthening the band-like pressing part 20 in the long axis direction, it is possible to minimize the deformation of the pressing part 20 in the case of mounting writing instruments having different body widths. Therefore, it is preferable that the push-in portion 20 be disposed so as to surround the finger insertion portion 10 and be bent upward near the center. By providing the connecting portion 15, both ends of the pressing portion 20 elongated in the long axis direction and the short side surface of the finger insertion portion 10 can be connected.

As a material of the pressing portion 20, a material that withstands the deformation stress at the time of wearing the writing instrument is preferable. Resin, metal, rubber, etc. can be used. The material of the connecting portion 15 is not particularly limited as long as it can withstand use.

The pressing unit 20 according to the present invention not only makes it possible to attach writing instruments having different body widths, but also contributes to the stabilization of the assist tool at the time of writing. By the action of each support portion (11, 12, 13), the finger insertion portion 10 is fixed to the index finger, and the adjacent middle finger presses the pressing portion 20 along the pressing portion 20 bent upward near the center . For this reason, the peristalsis of the aid is suppressed, and the fixation between the aid and the finger becomes more stable. Therefore, even when it is not possible to hold it by itself, stable writing can be performed with a natural writing sense.

The fulcrum portion 22 is in contact with the writing surface at the time of writing and supports the assisting tool. The shape of the fulcrum portion 22 is not limited. The fulcrum portion 22 can also be used as a part of the pressing portion 20 as illustrated in FIGS. 1 and 2. The fulcrum portion 22 preferably has a small contact area with the writing surface and a small frictional resistance. This is because the fulcrum portion 22 contacts the writing surface at the time of writing, maintains the distance between the writing surface and the fingers, and enables free writing operation. Resin, metal, rubber, paper, ceramic or the like can be used as a material of the fulcrum portion 22.

In order to be able to operate the self-help device freely at the time of writing, it is preferable that the fulcrum portion 22 protrudes from the tip of the index finger at the time of wearing the finger. At the time of writing, the fulcrum part 22 contacts the writing surface, and the tip of the writing instrument is moved up and down by minute rotation of the wrist supported by the contact point, and writing is performed. As a result, the hand load at the time of writing is greatly reduced, and stable natural writing is possible even when gripping by hand is not possible.

FIG. 4 is an explanatory view showing an example of the writing aid according to the present invention, which is attached to the index finger and stroked. The index finger is inserted into the finger insertion portion 10 of the assisting tool 1 and the middle finger is in contact with the pressing portion 20 to suppress and stabilize the peristalsis of the assisting tool 1. The writing instrument 2 is held by the finger insertion unit 10 and the pressing unit 20. The writing is performed by sliding the fulcrum 22 projecting from the tip of the index finger against the writing surface and slightly rotating the wrist with the fulcrum 22 as a fulcrum to move the tip of the writing tool up and down. There is no need for a gripping force to hold the aid at the time of writing, and horizontal movement and slight rotation of the wrist enable free and stable writing.
