Abstract

<P>PROBLEM TO BE SOLVED: To provide a sole plate for preventing pressure on a long plantar ligament in exercise such as walking. <P>SOLUTION: The sole plate includes projection and recession parts corresponding to the sole arch of a human body, wherein recession part 2 is provided at a part corresponding to the long plantar ligament of the sole arch and a cushion material 3 is mounted on the recession part 2. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a sole plate used as a shoe sole or an insole of a shoe.

  As shown in FIG. 3, an arch-shaped structure called a “plantar arch” is formed between the rib 5 and the seed bone 6 on the sole of a human who performs biped upright walking. The plantar arch plays a very important role in supporting a human weight and maintaining an upright posture from the skull through the cervical vertebra, lumbar vertebra, pelvis, femur, patella, and lower leg bone. Therefore, if the plantar arch collapses and the human foundation collapses, it will not be possible to maintain the correct upright posture to the skull, causing knee pain, back pain, stoop, etc., and posture that compresses the internal organs It may also cause.

  Thus, the maintenance of a normal plantar arch is very important for human health, and in order to retain this arch, conventionally, for example, as described in Patent Document 1, it corresponds to the plantar arch. It has been practiced to use a sole plate having an uneven part to be used as a shoe sole or an insole of a shoe.

  Although the use of the plantar plate is an effective means for holding the plantar arch, the plantar arch does not always have the same shape. That is, the rib 5 and the seed bone 6 at both ends of the plantar arch are connected by a ligament called “long plantar ligament” indicated by reference numeral 7 in FIG. 4, and the plantar ligament 7 expands and contracts during exercise such as walking. Accordingly, the shape of the sole arch also changes. The long plantar ligament 7 plays the most important role in maintaining the plantar arch, and it is important that the structure of the plantar plate also takes into account the stretchability of the long plantar ligament 7.

On the other hand, in the footplate described in Patent Document 1 described above, the elasticity of the long plantar ligament is not considered, and the long plantar ligament stretches during exercise such as walking and the height of the plantar arch is lowered. Each time, the long sole ligament is compressed by the convex part corresponding to the arch of the sole plate, and when this is repeated thousands of times or tens of thousands of times by walking for a long time, the long sole ligament becomes fatigued and eventually the long sole ligament The elasticity (elasticity) is lost and the shape of the sole arch cannot be maintained.
Registered Utility Model No. 3055368

  The problem to be solved by the present invention is to provide a plantar plate that can prevent compression to the long plantar ligament during exercise such as walking.

  The present invention is characterized in that in a plantar plate having an uneven portion corresponding to a human plantar arch, a depression is provided in a portion corresponding to the long plantar ligament of the plantar arch. A cushion material may be attached to the recess.

  According to the present invention, since the depression portion is provided in the portion corresponding to the long plantar ligament of the plantar arch, the long plantar ligament is not compressed by the plantar plate during exercise, and even when walking for a long time etc. The fatigue of the long plantar ligament can be reduced and the plantar arch can be held in a healthy shape.

  Hereinafter, embodiments of the present invention will be described based on examples shown in the drawings.

  FIG. 1 is a perspective view showing a sole plate of the present invention, and FIG. 2 is a cross-sectional view taken along line AA of FIG. The sole plate shown in the drawing has a convex arch portion 1 corresponding to the human sole arch shown in FIG. 3, and the arch portion 1 supports and holds the sole arch. The arch portion 1 is formed with a hollow portion 2 at a portion corresponding to the long sole ligament shown in FIG. 4, and soft rubber foam or the like is attached to the hollow portion 2 as a cushion material 3. A tanned skin 4 is applied to the entire surface of the sole plate.

  This plantar plate is produced by the following procedure. First, the user's foot shape is actually taken, and the plantar arch shape of the user is produced. Next, a slightly larger plantar plate is produced in consideration of the grinding of the corrected part, and this type of grinding machine grinds the plantar arch shape to the shape of the plantar arch shape while tracing the plantar arch shape. A plantar plate having the arch portion 1 having the same shape as that of the plantar arch type is produced. In addition, fine adjustments are made by the actual user. Thereafter, from the measured data such as the position, length, width, etc. of the long plantar ligament of the user, the portion corresponding to the long plantar ligament in the plantar plate is grasped, and the depression 2 is formed by punching with a punching press or the like. And if the cushion material 3 is mounted | worn in the hollow part 2, and the tanning skin 4 is finally affixed on the surface, a plantar board will be completed.

  As described above, in the embodiment, the cushion material 3 is attached to the recess 2, but the cushion material 3 is not essential. In the embodiment, the cushion material 3 is mounted so as to be flush with the surface of the sole plate, but may be mounted so as to slightly protrude from the surface of the sole plate. Furthermore, in the embodiment, the recess 2 is formed by punching, but a bottomed recess may be formed by grinding or the like.

  The present invention can be used as a shoe sole, an insole for shoes, or the like, and can also be used by being stuck or placed on the surface of a clog. In the case of clogs, a notch or the like for mounting a clog of the clogs is formed on the sole plate.

It is a perspective view which shows the sole plate of this invention. It is AA sectional drawing of FIG. It is a side view which shows a human sole. It is a figure which shows the long plantar ligament of a human sole.
