Description

The present invention relates to a finger bending orthodontic appliance. More specifically, it relates to a finger bending corrector that can approach a beautiful straight-shaped finger without finger bending.

Conventionally, when writing, it is practiced to soak the brush with ink before writing. There are two ways to hold the brush, the single hook method and the double hook method (see Non-Patent Document 1). In either method, when writing, do not put too much force on the finger holding the brush. carry.

However, in the early modern period, pencils became widespread, and ink writing became obsolete. Under these circumstances, in today's highly educated society, efforts are being made to improve the degree of learning and acquisition, and it is difficult to pay attention to the part of how to hold a pencil. As a result, many students have become accustomed to holding pencils in an inappropriate way.

If you get used to gripping a pencil in an improper shape without getting used to the correct grip at the beginning, correction is difficult. As an improper grip, for example, in the case of a right-handed person, press the pencil against the left side of the middle finger with the belly of the thumb, lift the second joint of the index finger extremely upward, and make a large bow near the first joint of the index finger. There is a way to hold it (see Fig. 5).
In this case, not only the degree of warpage of the bow near the first joint increases over time, but also the middle finger is deformed toward the ring finger side like a bow. That is, although the vicinity of the base of the middle finger generally faces the original direction of the finger, the bending width in the direction of the ring finger increases toward the tip (see FIG. 6).

The shape of the middle finger, which is bowed in this way, reduces the aesthetic appearance, and is a major factor in reducing the impression, especially in the present age when nail care is a business etiquette.

By the way, when a limb is broken, a bandage is wrapped around the limb while applying a splint to restrain the movement of the limb (Non-Patent Document 2). Similar measures can be taken for broken fingers. As a finger bending orthodontic appliance using this as a finger product, for example, "PYKES PEAK" (registered trademark) of EMI Trading Co., Ltd. is known.
This is a measure against a failure that occurs when a finger is used, but as a preventive measure when using a finger, a finger supporter that is less likely to cause finger pain or tiredness has been proposed (Patent Document 1 and Patent Document). 2).

Utility Model Registration No. 3115911 Jitsukaisho 60-52834 "Book ▲ 1 ▼", Educational Books, published on February 5, 2019, p.6 "Red Cross First Aid Training Textbook", Japanese Red Cross Society, published on April 1, 2013, p.84-93

However, in a finger bending corrector in which a splint is attached to a finger as described above to wind a bandage or a band member, the linear splint is approximately the average tangential direction of the centerline of the bowed finger. It is not enough as a measure to eliminate the bending of the middle finger by writing with a pencil. To put it more simply, it is similar to drawing a straight line with the least squares method for plot points arranged in a bow.
It is preferable that the fingertip side is corrected more than the root side of the middle finger.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a finger bending correction tool capable of appropriately eliminating finger bending and improving the aesthetic appearance of a finger.

As a result of intensive research on such a problem, the present inventor has found that the bending of the middle finger of the hand holding the pencil is larger than the bending of the middle finger of the hand holding the pencil due to the use of the pencil for many years. We recognized that the finger is a living tissue and that the living tissue deforms to the compression side when pressed for a long period of time, and found that the deformation of the finger can be eliminated by connecting them, and completed the present invention.

The finger bending correction tool of the present invention is provided with a guide member having a concave cross section and a long shape, and an elastic member provided on the inner side surface of the left and right walls of the guide member to urge the tip of the finger. ..

In such a configuration, a finger can be inserted into the long guide member from above along the guide direction, and then the finger can be pushed into the guide member while sliding on the guide surface. When the finger is inserted while sliding the pad of the fingertip, the tip of the finger comes to a position where it is sandwiched by a pair of elastic members on the left and right walls.

In this state, the pushing amount of the elastic member on the side where the finger is warped is larger than the pushing amount of the other elastic member, and a force is applied in the bending eliminating direction as a whole.
Further, since the finger is sandwiched between the elastic members, the finger is held by press fitting, and the finger can be reliably urged by the elastic member for a long time.

The position of the tip of the finger urged by the elastic member is preferably closer to the fingertip than the first joint.
In the case of an inappropriate pencil grip in which a force is applied to the part of the middle finger on the fingertip side from the first joint, the displacement of the part becomes larger than the displacement of the part corresponding to the opposite fingertip side of the first joint. When the finger bending corrector is used, a force can be applied to the portion on the fingertip side by an elastic member in the direction opposite to the finger bending side, which is preferable from the viewpoint of symmetry. This is because the fingertip portion is urged in one direction, that is, on the ring finger side when the pencil is gripped, and then urged in the other direction, that is, on the index finger side by the finger bending corrector.

Further, when the tip side of the first joint is urged, a force is also applied to the second joint, and a wider range of finger bending can be eliminated.

Further, in the finger bending corrector of the present invention, the size of the guide member is set so that the upper surface of the guide member is lower than the upper surface of the inserted finger when the finger is fitted in the recess of the guide member. It is preferable that it is decided.

In such a configuration, since the upper surface of the finger comes above the upper surface of the guide member, the finger is turned into the guide member by winding a tape or a bandage around the guide member with the finger fitted in the guide member. It can be fixed securely. Then, the fingertip can be urged by the elastic member in a stable state, and the finger bending can be eliminated by utilizing the bedtime or the like. Here, it is preferable to insert a spacer between the side surface of the finger and the left and right walls of the guide member to restrain the movement in the left-right direction.

Further, in the finger bending straightening tool of the present invention, it is preferable that the elastic member is a leaf spring.
In such a configuration, since a leaf spring is used, the finger can be smoothly press-fitted between the pair of leaf springs on the left and right walls, and a force can be applied to a wide area on the side surface of the finger for a long time. Local pain to the fingers is unlikely to occur even when wearing orthodontic appliances.

Further, in the finger bending correction tool of the present invention, it is preferable that the finger is the middle finger. This is especially effective for some people who have bent middle fingers due to improper holding of the pencil.

In the finger bending corrector of the present invention, a guide member having a concave cross section and a long shape and an elastic member for urging the tip of the finger are provided on the inner side surfaces of the left and right walls of the guide member, and the finger bending straightening tool has a long shape. A finger can be inserted into the guide member from above along the guide direction, and then the finger can be pushed into the guide member while sliding on the guide surface. Then, when the finger is inserted while sliding the pad of the fingertip, both side surfaces of the tip of the finger come to a position where they are sandwiched by the elastic members.

In this state, the pushing amount of the elastic member on the side where the finger is warped becomes larger than the pushing amount of the elastic member on the other side, and the finger is displaced in the bending eliminating direction. If this state is held for a long time, the bending of the finger is displaced to the elimination side, and the aesthetic appearance of the finger can be improved.

Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.

FIG. 1 is an explanatory diagram showing an embodiment of the finger bending orthodontic appliance of the present invention. The finger bending straightening tool 1 of the present embodiment is provided on the inner side surfaces of the guide member 2 having a concave cross section and a long shape and the left and right walls 2a and 2b of the concave guide member 2 and urging the tip of the finger. A pair of leaf springs 3 which are elastic members are provided. A metal material is used for the guide member 2 and the leaf spring 3, and for example, phosphor bronze is used as the leaf spring 3. In order to fix the leaf spring 3 to the guide member 2, the guide member 2 and the leaf spring 3 are fused with solder.

The material of the guide member 2 and the leaf spring 3 is not limited to the metal material, and may be a resin, and is not particularly limited. If it is made of resin, it doesn't feel too heavy even if you attach it to your finger and live your daily life.

It is also possible to fix the leaf spring 3 to the guide member 2 with rivets, and the fixing method is not particularly limited.
The concave cross-sectional shape of the guide member 2 includes not only an accurate U-shaped cross-section but also a cross-sectional shape on which a finger can be placed. It may have a substantially concave shape.

If the middle finger is slightly bent, the finger can be held in a linearly deformed state by inserting the finger into a mere linear concave groove. However, when the bending is large to some extent, a large stress is applied to the finger when trying to correct the bending only by the groove. In such a case, the finger bending correction tool 1 of the present embodiment is particularly effective. This is because the leaf spring 3 can urge the finger for a long time with an appropriate force.

FIG. 2 shows a state before and after inserting the middle finger into the finger bending correction tool 1 of FIG. When inserting the middle finger into the finger bending orthodontic appliance 1, first, the middle finger is inserted into the long guide member 2 from above along the guide direction, and then the finger is inserted into the guide member 2 while sliding on the guide surface. Be pushed in. Then, when the fingertip is inserted while sliding, as shown in FIG. 2A, both side surfaces of the tip of the middle finger come to the position immediately before being sandwiched by the pair of leaf springs 3.

The corner 3a may be covered with solder or tape so that the finger does not get caught in the edge of the corner 3a of the leaf spring 3 when the finger is inserted.
Further, when the fingertip is inserted while sliding, as shown in FIG. 2B, the tip of the middle finger comes to a position where it is sandwiched by the pair of leaf springs 3.

In this state, the pushing amount of the leaf spring 3 on the side where the middle finger is warped is larger than the pushing amount of the other leaf spring 3, and a force is applied in the direction of eliminating the finger bending as a whole. If this state is held for a long time, the middle finger is displaced to the side where the bending is eliminated.
The vicinity of the base of the middle finger generally faces the original direction of the finger, and the amount of bending displacement increases toward the tip. More properly expressed, the fingertip side tends to have a larger curvature.
The shape of the change in finger width along the longitudinal direction of the finger differs from person to person, but the width tends to become narrower toward the fingertip side.

If the leaf spring 3 is used as the elastic member, the middle finger can be smoothly press-fitted between the pair of leaf springs 3, and a force can be applied to a wide area on the side surface of the middle finger. Even if you wear it, local pain to your fingers is unlikely to occur.

The elastic member is not limited to the leaf spring 3, and may be a push rod such as a pin. When a structure in which the pin can be pushed is used, it is preferable to provide a curved tile plate-shaped member that matches the shape of the outer peripheral surface of the finger at the tip of the pin.

The position of the middle finger urged by the leaf spring 3 is preferably on the fingertip side of the first joint.
A leaf spring 3 can apply a force to the fingertip side portion in the direction opposite to the finger bending side, which is preferable from the viewpoint of symmetry. This is because, when the pencil is gripped, the fingertip portion is urged in one direction, that is, the ring finger side, and then the finger bending corrector 1 is urged in the other direction, that is, the index finger side.

Further, when the tip side of the first joint is urged, a force is also applied to the second joint, and a wider range of finger bending can be eliminated.

It is known that when pressure is applied to a living body, the living body changes in the direction of compression over time. For example, the Plesiosauria and the giraffe. Turtles in the Galapagos Islands also have long-necked species to suit the environment. In addition, Thai Kayan people have a large number of neck joints and long joints due to the custom of wearing collars. It can be seen that each individual stretches its neck from generation to generation.

FIG. 3 shows a state in which the middle finger is inserted into the finger bending correction tool 1 of FIG. FIG. 3A is an upside-down view of FIG. 2B, and FIG. 3B is a view seen from the fingertip side. As shown in the figure, one leaf spring 3 is pushed in from the other leaf spring 3, and the middle finger is urged in the direction of the arrow in the figure as a whole.

The size of the guide member 2 is determined so that the upper surface of the guide member 2 is lower than the upper surface of the middle finger. Assuming an average adult finger size, specify how many fingers it is for, and sell each finger separately, for example, S size, M size, and L size.

In this way, when the upper surface of the guide member 2 is set to be lower than the upper surface of the middle finger, the upper surface of the middle finger comes above the upper surface of the guide member 2, so that the guide member is in the state where the middle finger is inserted into the guide member 2. By wrapping a tape, a bandage, or the like around the 2, the middle finger can be securely fixed to the guide member 2.

Here, in order to restrain the movement of the middle finger in the left-right direction, it is desirable that the width of the second joint just fits into the recess, but if this is not the case, as shown in FIG. 4, the vicinity of the second joint Spacers S1 and S2 may be inserted between the middle finger and the groove of the guide member 2.
Then, the fingertip of the middle finger can be urged by the leaf spring 3 in a stable state, and it is possible to eliminate the bending of the finger by utilizing the bedtime or the like.

In the finger bending corrector 1 of the above-described embodiment, the guide member 2 having a concave cross section and a long shape and a pair of plates for urging the tip of the middle finger on the inner side surfaces of the left and right walls 2a and 2b of the guide member 2. A spring 3 is provided, and the middle finger can be inserted into the long guide member 2 from above along the guide direction, and then the middle finger can be pushed into the guide member 2 while sliding on the guide surface. When the middle finger is inserted while sliding the pad of the fingertip, both side surfaces of the tip of the middle finger come to a position where they are sandwiched by the pair of leaf springs 3.

In this state, the pushing amount of the leaf spring 3 on the side where the finger is warped becomes larger than the pushing amount of the other leaf spring 3, and a force is applied in the bending eliminating direction as a whole. As a result, by wearing the orthodontic appliance 1 for a long period of time, the finger is deformed to the side where the bending of the middle finger is eliminated, and the aesthetic appearance of the middle finger can be improved.

Further, since the middle finger is sandwiched by the leaf spring 3, the middle finger is held by press fitting, and the middle finger can be reliably urged by the leaf spring 3 for a long time.
The finger bending orthodontic appliance 1 of the present embodiment can be relatively easily manufactured without any structural complexity.

Although the present invention has been described above, it goes without saying that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the essence of the present invention.

For example, in the above-described embodiment, an example using a pair of leaf springs 3 has been described, but a U-shaped spring or a C-shaped spring in which the left and right leaf springs are integrated may be used. Any form may be used as long as the fingers can be pinched from the left and right.

The present invention can be used as a finger bending orthodontic appliance. In particular, it is suitable for improving the aesthetic appearance when the middle finger is warped due to improper gripping of the pencil and the aesthetic appearance is deteriorated. In addition, for those who aim to become pianoists in the future, it is desirable to correct finger bending, so application to music-related fields is also effective.
