Description

  The present invention relates to a foot orthosis for preventing unevenness.

Symptoms of foot slipping at bedtime are convulsions of the muscles of the feet, often occurring in the calves (komura), so it is said to be “swinging back”. In the lower limbs, it occurs frequently in the muscles of the thighs and calves, but it is said that the soles of the feet and the toes of the feet hang, and the cause is abnormal muscle contraction.
If you have to take first aid when your feet are swollen, the calf and sole muscles will remain stiff and stiff. In this state, care must be taken because flare (muscular contusion) sometimes occurs.
It seems that foot hangs frequently during sleep, in the morning, when the child stretches casually in the bed, etc., but occurs during swimming as well as during sleep. This is thought to be due to the rapid contraction of calves and sole muscles during kicks in swimming.

Based on the cause of the above-described unevenness, there is a concept of preventing the occurrence of unevenness by stretching the muscles of the sole at bedtime.
For example, as shown in FIG. 12, Patent Document 1 includes a thigh support cushion 1 and a lower leg cushion 2 that are longer than the lower leg length and thicker or stiffer than the trunk, and ankle joints are produced when unevenness occurs. A sleeping lower limb cushion having various shapes such as a ring shape and a bag shape, which is a combination of a foot-clamped bottom macula 3 and an elastic coupling body 4 such as a rubber band, is described. This sleeping lower limb cushion has a lower limb placed on the thigh support cushion 1 superimposed on the lower leg cushion 2 at the time of sleeping, and a rubber band or the like is placed between one end of the lower leg cushion 2 and the toe thumb. The thumb is pulled toward the lower leg cushion 2 by tensioning the component. By pulling this thumb toward the lower leg cushion 2, the muscles of the sole (arch) and calf are stretched, preventing sudden contractions in the sole and calf muscles, thereby preventing stiffness. It is thought to be prevented.

  Further, Patent Document 2 describes another way of thinking. As shown in FIG. 13, this is a walking aid that combines an ankle cushion pad 5, a cushion composed of a footrest strap 6 such as rubber for hooking the footpad, and leg warmers and supporters 7. It is a brace that also has strength training function. In this brace, the calf part is covered with the supporter 7 and the cushion pad 5 to keep the lower leg warm and prevent back-rolling, and the toe strap 6 with the end fixed to the cushion pad 5 is hung on the thumb. Is pulled in the direction of the cushion pad 5 to stretch the muscles of the soles of the feet, so that no unevenness occurs.

JP 2008-104827 A Utility Model Registration No. 3089365

However, in the above-described conventional non-uniformity prevention device, the direction of the force for pulling the thumb A is the direction of the end of the lower limb support cushion 2 placed under the lower limb in Patent Document 1, and the calf in Patent Document 2 It is the direction of the cushion pad 5 attached to. The direction of these forces is schematically shown in FIG. Due to such directionality of the force, in the above prior art, the force pulling the thumb A causes a bending moment at the joint J of the heel. This force acts to reduce the angle θ formed by the lower limb center line i and the sole line k shown in FIG. As a result, the following inconveniences A and B occur.
A. For example, when this brace is used in bedtime to prevent backlash, a bending moment is applied to the heel joint J for a long time in the bedtime state, which causes pain to the user.
B. It is desirable that such a brace can be worn not only at bedtime but also in a normal living state, for example, walking, to prevent backlash, but in the brace described in Patent Document 2 shown in FIG. Pulled forward, the person is picked forward while walking, making walking difficult in practice. In the orthosis described in Patent Document 1 shown in FIG. 12, the thigh support cushion 1 and the crus cushion 2 are indispensable, and cannot be used in scenes where people usually get up and live.
Furthermore, as described above, it is well known that unevenness occurs even when swimming, and it is desirable that such an appliance can be worn even when swimming to prevent unevenness. However, the orthosis described in Patent Document 2 is not suitable for swimming because the supporter 7 and the cushion pad 5 which are essential components are obstructive. In the orthosis described in Patent Document 1, the thigh support cushion 1 and the crus cushion 2 are essential, and cannot be used for swimming.

  Accordingly, a first object of the present invention is to provide a non-turn-back prevention device that does not apply a bending moment to the heel joint J and does not give the user pain to the heel joint J even when worn for a long time. . Furthermore, a second object of the present invention is to provide an unevenness prevention device that can be used during swimming.

In order to achieve the above-described object,
A brace that lifts the big toe to prevent it from rolling back,
One end is connected to the thumb sack member to be attached to the thumb and the rear end of the thumb sack member, and when the other end is attached to the thumb sack member, the other end is stretched over or near the heel of the foot. Or a left and right connecting band member that pulls in the direction in the vicinity thereof,
The thumb sack member is configured as a non-flipping prevention device connected to the connecting band member so that the thumb suck member is pulled by the connecting band member to urge the thumb in the direction of lifting the toe of the thumb when worn.
In this unevenness prevention device, one end of the connecting band member is stretched over or near the heel of the foot, so that even if the force to lift the toe of the thumb is applied to or near the heel of the foot, Does not generate or hardly generate moments to bend. At this time, if the direction of the force to lift the toe of the thumb is below the heel joint, there is no moment to try to bend the heel joint. Thus, in order to make the direction of the force for lifting the toe of the thumb downward, a deflecting means for deflecting the connecting band member in the sole direction may be used. As an example of such a deflecting means, in the present invention, when worn on the foot, it is laid over the left and right connection band members from the sole of a person and assists the right and left connection band members in the sole direction. A belt member can be provided.
Furthermore, the connecting band member in the present invention is preferably provided with a length adjusting means for adjusting the length in accordance with the size of a person's foot. Thereby, it is possible to appropriately adjust the pulling force of the thumb sack member regardless of the size of the person's foot to be used.
Further, it is desirable that the connecting band member and / or the auxiliary belt member itself is made of an elastic body that can be expanded and contracted. As a result, the connecting band member and / or the auxiliary belt member does not sag, and an unevenness prevention device that always obtains an appropriate pulling force and fits snugly to the foot can be configured.
The whole non-uniformity prevention device may be made of an elastic body that can be expanded and contracted. In this case, the entire brace is exactly along the foot, and a comfortable wearing feeling can be obtained.
As described above, the non-uniformity prevention device of the present invention is a device for preventing the nonuniformity by lifting the big toe, and has one end connected to the thumb sack member to be attached to the thumb and the rear end of the thumb sack member. And the left and right connecting band members that, when worn, are stretched over or near the heel of the foot to pull the thumb sack member in the direction of the heel or the vicinity thereof, and the thumb sack member includes: Since it is configured as an anti-flipping device connected to the connecting band member so as to urge the thumb in the direction of lifting the toe of the thumb when pulled by the connecting band member, the thumb suck member Insert the thumb and hang the connecting band member on or near the heel. Pull in. At this time, since the thumb sack member is pulled by the connecting band member and the toe of the thumb is lifted, the muscles of the soles and the calves are prevented from contracting, and the occurrence of unevenness is prevented.
In this case, since the force to lift the thumb generated by the connecting band member is in the direction of the heel or the vicinity thereof, even if a bending moment is not generated in the joint of the heel portion due to this force, It is slight. This is because the length of the arm that generates the bending moment is zero or nearly zero.
Therefore, in the non-uniformity prevention device of the present invention, the bending moment is not generated or hardly generated in the joint portion of the heel as described above even when used for a long time in a normal use state, for example, in a sleeping state. For example, there is no problem in conventional devices such as Patent Document 2 or Patent Document 1 that causes pain.
In addition, it is desirable that such a brace can be worn not only at bedtime but also in a normal living state, for example, during walking, so that it can be prevented from turning back and forth. However, in the orthosis described in Patent Document 2 shown in FIG. 13, the lower limbs are pulled forward and the person is “pushing” forward when walking, which makes it difficult to walk in practice. When the brace is used, the force to lift the thumb generated by the connecting band member as described above is in the direction of the heel itself or in the vicinity thereof, so that no bending moment is generated in the joint of the heel portion by this force. As a result, in the non-uniformity prevention device according to the present invention, walking is not hindered, and there is no problem of feeling tired during walking.
Furthermore, as described above, it is known that unevenness occurs even during swimming. However, in the orthosis described in Patent Document 2, the supporter 7 and the cushion pad 5, which are essential components, interfere with the swimming. Not suitable. On the other hand, the non-uniformity prevention device according to the present invention has a structure that is in close contact with the foot, and requires a member that obstructs swimming, such as the supporter 7 and the cushion pad 5 such as the device described in Patent Document 2. Therefore, it can be worn even when swimming, and the unevenness of swimming can be prevented appropriately.

In the anti-return device of the present invention, the thumb sack member is pulled by the connecting band member and the toe of the thumb is lifted in use, so that the muscles of the soles are prevented from contracting and the occurrence of unevenness is prevented. At the same time, since no bending moment is generated in the joint of the heel portion, there is no problem in the conventional appliances that give pain to the user.
For the same reason, since no bending moment is applied to the joint of the heel portion that hinders walking, there is no problem in the conventional orthosis that causes pain to the user in the walking state.
Furthermore, since it consists only of a structure similar to a simple supporter, there is no structure that obstructs swimming, it can be worn even during swimming, and it is suitable as a non-uniformity prevention device for swimming.
Furthermore, as described above, in the non-uniformity prevention device according to the present invention, since the thumb is lifted during walking, it is needless to say that it is possible to prevent so-called “stumbling” in which severe pain is caused by colliding with a small step or the like. .

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, terms indicating specific directions and positions (for example, “up”, “down”, “right”, “left” and other terms including those terms) are used as necessary. . The use of these terms is to facilitate understanding of the invention with reference to the drawings, and the technical scope of the present invention is not limited by the meaning of these terms. Moreover, the part of the same code | symbol which appears in several drawing shows the same part or member.

As shown in FIGS. 1 to 11, the non-uniformity preventing device 10 is a device for lifting the thumb A of the foot C to prevent the nonuniformity.
More specifically, the non-uniformity prevention device 10 has a thumb sack member 12 attached to the thumb A, and one end 14A connected to the rear end of the thumb sack member 12, and the other end when attached to the foot C. 14B is stretched over the heel B of the foot C to pull the thumb suck member 12 in the direction of the heel B, and the left and right connection band members 14 from the sole D of the person when worn. And an auxiliary belt member 16 that urges the left and right connecting band members 14 in the sole D direction.

In this embodiment, the entire non-uniformity prevention device 10 is composed of an integral elastic member made of a thin rubber film that expands and contracts, and the thumb sack member 12 has the above-described configuration when the non-uniformity prevention device 10 is attached to the foot C. The connecting band member 14 is connected to the connecting band member 14 so that the thumb A is biased in a direction in which the toe A1 of the thumb A is pulled upward by being pulled by the connecting band member 14. The direction of the force that lifts the toe A1 upward is indicated by an arrow X in FIG.
In this embodiment, the entire non-uniformity prevention device 10 is formed of an integral elastic member made of a thin rubber film that expands and contracts, but the entire non-uniformity prevention device 10 or a part thereof may be configured by an inelastic material. For example, cloth, leather, non-woven fabric, etc. may be used. In that case, it is desirable to provide an adjustment to match the size of the foot C. Adjustment means for adjusting the size of the foot C and adjusting the tension of the thumb sack member 12 by adjusting the position of the coupling portion at the rear end of the connecting band member 14 will be described later.
As described above, the thumb sack member 12 is pulled by the connecting band member 14 to pull the toe A1 upward when the non-uniformity prevention device 10 is attached to the foot C. It is also one method that the member 12 is connected to the connecting band member 14 at an inclination, but only the upper surface of the thumb suck member 12 is connected to the connecting band member 14, and the thumb suck member 12 A configuration in which the thumb A is rotated upward by pulling the upper surface may be employed. In the form shown in the figure, the thumb suck member 12 is connected to the connecting band member 14 at an angle, and only the upper surface thereof is connected to the connecting band member 14. Yes.

Since the non-uniformity prevention device 10 according to this embodiment is configured as described above, the thumb A is inserted into the thumb suck member 12, and the connecting band member 14 is pulled and hung on the heel B, thereby connecting the band member. 14 pulls the thumb sack member 12 in the direction of heel B by its own elastic function. At this time, the thumb suck member 12 is pulled by the connecting band member 14, and the toe A1 of the thumb A is lifted upward. As the thumb A is pulled in the direction of the instep of the foot C in this way, the muscle of the sole D is stretched and the muscle of the sole D is not contracted, thereby preventing the occurrence of unevenness.
In the illustrated embodiment, as described above, the connecting band member 14 is pulled to be hung on the heel B when attached to the foot C. However, it is not always necessary to hang on the heel B itself. It may be hung on the vicinity, for example, the part of the Achilles tendon following the heel B. In particular, when the auxiliary belt member 16 described later is used, the direction in which the thumb sack member 12 is pulled can be set to the direction of the heel B even if the connecting band member 14 is hung on the Achilles tendon.

This embodiment further includes an auxiliary belt member 16 that is stretched from the sole D of the person to the left and right connecting band members 14 when urging the foot C to the left and right connecting band members 14 in the direction of the sole D. It is configured with.
As shown in FIG. 14, if the angle β between the direction of the force W pulling up the thumb A and the direction of the sole surface increases, the bending moment applied to the joint J of the heel B increases, so that it can be used for a long time. It will be unbearable. In order to avoid such an inconvenience, the direction of the force W for pulling up the thumb A may be deflected toward the heel B or the vicinity thereof. The auxiliary belt member 16 is an example of a deflecting unit that deflects the direction of the force W for pulling up the thumb A in the direction of the heel B or the vicinity thereof. The auxiliary belt member 16 biases the middle part of the left and right connecting band members 14 in the sole direction, so that the direction of the pulling force by the left and right connecting band members 14 is deflected in the direction of heel B or the vicinity thereof. Is done. As a result, the bending moment applied to the joint J of the heel B is prevented, and the joint J of the heel B does not feel tired even when used for a long time.
The auxiliary belt member 16 itself is made of a material such as a thin rubber film, but this is only an example, and it may be an inelastic member such as a string or cloth.
Further, as described above, the position of the arch is suitable for the place where the auxiliary belt member 16 is placed, but it may be a wide surface extending from the arch to the lower surface of the heel B, or only the lower surface of the heel B. .

In this embodiment, the length of the connecting band member 14 can be adjusted according to the size of a person's foot. That is, hook and loop fasteners 18A and 18B such as Velcro (registered trademark) are sewn to the other end 14B of the left and right connecting band members 14, and the connection is made by adjusting the joining position of the hook and loop fasteners 18A and 18B. The length of the band member 14 can be adjusted. Thereby, it is possible to appropriately adjust the force for pulling the thumb suck member 12 regardless of the size of the foot C of the user.
The hook-and-loop fasteners 18A and 18B are examples of the length adjusting means in the present invention, but other examples of the length adjusting means may be buttons, hooks, and the like. Alternatively, a method may be used in which the ends of the left and right connecting band members 14 are tied to each other at a free length position so as to match the size of the foot C.

Further, as described above, since the non-uniformity preventing device 10 as a whole, or at least the connection band member 14 itself is made of an elastic body that can be expanded and contracted, the connection band member 14 does not sag and is always appropriate. High pulling force can be obtained. It is important for wearing for a long time that an appropriate force is not applied to the foot C by such an appropriate tension, and thereby it is possible to prevent human fatigue.
As described above, the entire non-uniformity prevention device 10 may be formed of an elastic body that can be expanded and contracted. In this case, the entire brace is exactly along the foot C, and a comfortable wearing feeling can be obtained.

As described above, in the non-uniformity prevention device 10 according to this embodiment, the thumb A is inserted into the thumb suck member 12 and the connecting band member 14 is hung on the heel B, whereby the connecting band member 14 pulls the thumb suck member 12 down. Pull in the direction of 踵 B or its vicinity. At this time, since the thumb sack member 12 is pulled by the connecting band member 14 and the toe A1 of the thumb A is lifted, the contraction of the muscles of the sole D is prevented and the occurrence of unevenness is prevented.
In this case, since the force to lift the thumb A generated by the connecting band member 14 is in the direction of the heel B itself or in the vicinity thereof, no bending moment is generated in the joint of the heel B portion by this force. This is because the length of the arm that generates the bending moment is zero.
Therefore, in the non-uniformity prevention device 10 according to this embodiment, even if it is used for a long time in a normal use state, for example, in a sleeping state, a bending moment is not generated in the joint portion of the heel B as described above. There is no problem of giving pain. Thereby, the problem in the conventional appliances, such as patent document 1 or 2, for example, does not arise.

  In addition, it is desirable that such an unevenness prevention device 10 can be worn on the foot C not only at bedtime but also in a normal living state, for example, when walking, so as to prevent unevenness. In this regard, in the orthosis described in Patent Document 2 shown in FIG. 13, the lower limbs are pulled forward and the person picks them forward during walking, which makes it difficult to walk in practice. However, the non-uniformity prevention according to this embodiment is prevented. When the brace 10 is used, the force to lift the thumb A generated by the connecting band member 14 as described above is in the direction of the heel B itself, and this force generates a bending moment at the joint of the heel B portion. do not do. As a result, in the non-uniformity prevention device 10 according to this embodiment, walking is not hindered, and a problem that causes fatigue in walking does not occur.

  Further, as described above, it is known that the unevenness occurs even when swimming, but the supporter 7 and the cushion pad 5 which are essential components in the orthosis described in Patent Document 2 are not suitable for swimming. Absent. On the other hand, the non-uniformity prevention device 10 according to this embodiment itself has a structure like a supporter that is in close contact with the foot C, and therefore swimming such as the supporter 7 and the cushion pad 5 like the device described in Patent Document 2 above. Therefore, it is possible to appropriately prevent unevenness during swimming.

As described above, in the non-uniformity prevention device 10 according to the above embodiment, the thumb sack member 12 is pulled by the connecting band member 14 and the toe A1 of the thumb A is lifted in the use state. The contraction of the muscle is prevented, the occurrence of unevenness is prevented, and at this time, no bending moment is generated in the joint of the heel B portion, so that there is no problem in the conventional orthosis that causes pain to the user.
Further, for the same reason, no bending moment is applied to the joint of the heel B portion that hinders walking, so that there is no problem in the conventional orthosis that causes pain to the user in the walking state.

Furthermore, since it consists only of a structure similar to a simple supporter, there is no structure which obstructs swimming, and it is suitable as a non-uniformity prevention apparatus for swimming.
Furthermore, as described above, in the non-uniformity prevention device 10 according to this embodiment, since the thumb A is lifted during walking, so-called “stumbling” in which severe pain is caused by colliding with a small step or the like is prevented. Can do.

  The present invention can be applied to a brace for preventing the foot from rolling back.
