Description

  The present invention relates to a slipper mainly used for indoor wear, which can improve the metabolism of the body by correcting the posture of the whole body by encouraging the user to actively use the five toes during walking. It relates to slippers that can be used.

Inappropriate posture of the body is known to cause symptoms such as back pain, stiff shoulders, headache, and visceral upset. One of the fundamental causes is the fact that modern people who wear shoes outdoors and wear footwear such as slippers indoors in daily life do not use footpads very much during walking.

Originally, the basic posture of the human body during activity is that the pelvis is tilted slightly forward. When gaining forward propulsive force with the legs during walking, support the majority of the body weight in the forefoot part of the sole, especially in the vicinity of the metatarsal joint joint (so-called MP joint) where the metatarsals and ribs bend, Then it is natural that all of the toes touch the ground and move together. However, many modern people have become accustomed to the fact that the movement of the toes is restricted by footwear, so they do not use the toes much for walking, and as a result, the weight tends to be put on the toes and the pelvis is behind It tends to tilt.

When the pelvis tilts backward, the adductor muscles of the thighs are less likely to be utilized, so both legs inevitably become the inner crotch, and it feels like a "sliding foot" where the toes do not rise sufficiently during walking. Therefore, the soleus muscle of the calf and the hamstring muscle group extending from the thigh to the buttocks cannot be used effectively. As a result, the blood flow in the legs will be sluggish, causing symptoms such as “cold” and “swelling” of the legs, especially in women, and knee pain, hip pain, and back pain in the elderly. Become.

In addition, the back of the pelvis becomes “stoop-back” and the internal organs are affected. Since the muscles of the whole body basically move in front and back, and a pair of left and right, the “nose back” that does not use the muscles of the back causes the abdominal muscles to relax and cause the internal organs to drop, causing the lower abdomen to appear. Furthermore, in the “stoop-back” state, the diaphragm, which is a muscle for breathing, is also loosened and breathing is constantly shallow, resulting in a decrease in metabolism and a variety of poor physical condition. The adverse effect of such “back of the cat” is becoming even younger due to the recent spread of smartphones and the like.

In order to solve the problem of posterior tilt of the pelvis without difficulty, it is effective to encourage active use of the footpad. As shown in the skeleton diagram of the foot bone in FIG. 1, the number of the ribs is different between the first toe (heel) and the four fingers from the second to the fourth toe. For this reason, the movements of the first and other fingers are difficult to coordinate, and particularly in the “inner crotch” state, the movements of the second to fourth hooks tend to be sluggish together. On the other hand, in the case of a human whose pelvis is inclined backward and has an inner thigh tendency, the body weight tends to be applied to the first toe among the five fingers, and the first toe moves actively during walking.

In normal footwear such as shoes and slippers, since five toes converge at the toe portion, the movement of the toes is restricted. On the other hand, as disclosed in Patent Documents 1 and 2, shoes having a structure in which a toe is divided into two portions and having a high degree of freedom of movement of the toes have been proposed.
Japanese Patent Laid-Open No. 2-68001 Japanese Utility Model Publication No. 6-84902

However, these prior arts have a structure in which the toes are divided into two forks between the first and second heels, and the degree of freedom of movement of the first heel increases, but the remaining second to fifth heels. The four fingers are still tied together, which is no different from conventional footwear. For this reason, the above-mentioned inner thigh tendency is not improved, and the effect of improving and preventing symptoms caused by pelvic tilt and stoop is hardly expected.

In addition, slippers used for indoor wear are relatively small in tightening the toes and less restricted in freedom of movement of the toes compared to outdoor shoes, but the bottom is generally flat. It does not have the effect of encouraging active use of toes.

The slipper according to the present invention solves the problems of the prior art and is used as an indoor footwear in daily life, so that the pelvis is increasing in general people regardless of the presence of flat feet, hallux valgus and club pinkie The problem is to prevent and improve diseases and poor physical condition caused by backward tilt and stoop.

In order to solve the above problems, in the slipper according to claim 1 of the present invention, the toe portion accommodates the inner toe portion that accommodates the first and second collars, and the third to fifth collars. It is divided into two forks on the outer toe, and further, a grounding piece is provided on the lower surface of the lower bottom, and when the slipper is worn, the grounding piece pushes the lower bottom upward, A vertically long convex part is formed rearward along the sole axis from a portion corresponding to the middle foot joint joint of the third foot.

In such a configuration, the toe portion has a bifurcated structure of an inner toe portion that accommodates the first and second heels and an outer toe portion that accommodates the third to fifth heels (small heels). Therefore, the second hook moves positively with the first hook in the inner toe portion. As a result, the third to fourth wings are also activated by the movement of the second heel, and inevitably urged to use all five toes.

In addition, since the first and second hooks and the third to fifth hooks are bundled and moved by the inner and outer toe portions, respectively, the second and fourth hooks move only one at a time in a normal state. The heels, especially the second heel and third heel, will move separately, prompting the user to be aware of each one of the toes and directing the toes to be actively used.

Further, the slipper according to the present invention is provided with a grounding piece on the lower surface of the lower bottom, and when the slipper is worn, the grounding piece pushes the lower bottom upward, so that the second heel and the third heel of the bottom sole When the user stands or walks, the convex portion is formed so that a longitudinally long convex portion is formed rearward along the sole axis from the position corresponding to between the middle foot phalanx joints. This pushes up the middle foot joint of the second and third base.

The human body has a variety of reflexes, but its functions include visceral reflex (autonomic nerve reflex) that contracts visceral muscles and promotes gland secretion via the autonomic nervous system, and contracts skeletal muscles. It is roughly divided into somatic reflection. The patella tendon reflex, in which the lower leg jumps when the patellar tendon is struck with a mallet, is one of the typical somatic reflexes. It is known medically and empirically to show somatic reflexes that round the eye. The slipper according to the present invention uses the somatic reflex of the toes generated by pushing up the middle toe joints at the convex portions to make the user round the toes and actively use the toes while walking The purpose is to encourage. Also, as the base of the second and third heels is pushed up, the five toes draw a gentle arch with the position of the crotch of the second and third heels as viewed from the front, In combination with the bifurcated shape, in particular, the fifth hook is pressed against the bottom surface.

The fifth base (little finger) originally plays an important role in controlling the balance of the body when standing up and walking, but the fifth base tends to rise up unconsciously in the inner thigh posture. Thus, as described above, the pelvic tilt and stoop are likely to occur. Such a configuration of the present invention is intended to improve the overall posture of the body by encouraging the fifth base to be used while being actively grounded.

Next, in the invention described in claim 2, the toe portion has a bifurcated structure of an inner toe portion that accommodates the first and second heels and an outer toe portion that accommodates the third to fifth heels. Is the same as the first aspect of the invention, except that a grounding plate is provided on the lower surface of the lower sole with the position of the midfoot phalanx joint of the sole as the front end and the position of the rear end of the middle foot (arch) as the rear end. Therefore, when the slipper is worn, a step is formed at the front end of the ground plate where the tip of the lower base hangs down on the toe side (hereinafter referred to as “toe side step”), and at the rear end, the rear end of the lower bottom is A step that hangs down to the heel side (hereinafter referred to as “step side step”) is formed.

According to this configuration, when the slipper is worn, the user's footpad is naturally rounded by the toe side step, and the middle foot (arch) is pushed up by the heel hanging down by the heel side step. Therefore, the arch shape in the front-rear direction of the sole is adjusted. As a result, the user is in a state where the tip of the toe grips the upper surface of the lower bottom during walking, and is aware of the use of the toe.

Next, the invention described in claim 3 is the invention described in claim 2, further comprising a protrusion corresponding to the grounding piece in the invention described in claim 1 at the front end of the grounding plate. When wearing, the protrusion pushes up the lower sole upward, so that it can be moved backward along the sole axis from the position corresponding to the middle foot joint joint of the second foot and the third foot of the third foot. A vertically long convex portion similar to that in the device described in claim 1 is formed.

According to such a configuration, in addition to the effect of drooping the toes and heels by the configuration of the slipper according to claim 2, the effect of somatic reflex by pushing up the metatarsal joint joint by the configuration of the slipper according to claim 1 Works synergistically, and the effect of making the user roll the toe so that the tip of the toe grips the upper surface of the lower bottom is further exhibited.

Finally, the invention described in claim 4 is the slipper according to any one of claims 1 to 3, wherein the toe portion has a lower bottom divided into two forks, an outer toe portion and an inner toe at the tip. It is characterized in that it is composed of a honey that is divided into two parts.

  The configuration of the toe portion may be bifurcated with only the shape of the honey while the shape of the lower base is the same as that of a normal slipper. In addition to increasing the degree of freedom of moving each separately, the effect of somatic reflection by pushing up the metatarsal joint joint with the convex portion is also enhanced.

  The slipper according to the present invention has an effect of improving posterior tilt of the pelvis naturally only by prompting the user to use the footpad, correcting posture, maintaining muscle strength, and improving metabolism. Specifically, it is formed on the upper surface of the lower bottom while forcibly synchronizing the movements of the first and second toes of the toes with a bifurcated toe to coordinate the overall movement of the five toes. Steps and bumps cause the toes to unconsciously round the toes so that all toes grab the upper surface of the lower base. In particular, the fifth toes are grounded to encourage active use. In addition, the effect of rounding the toes is further enhanced by the step formed at the location where the lower foot metatarsal joint and the arch back end contact.

Therefore, by wearing the slippers according to the present invention, the strength of the toes is positively strengthened even indoors, and the ability to hold the center of gravity axis of the body during walking and exercise increases, so elderly people with particularly weak muscle strength The effect that it leads also to prevention of fall accidents, such as these, can be expected.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 2 is a perspective view of a slipper according to the present invention, and FIG. 3 is a plan view.

(First embodiment)
4 to 9 are views of the slipper according to the first embodiment. FIG. 4 is a bottom view, FIG. 5 is a front view, and FIG. 6 is a rear view. 7 is a cross-sectional view taken along the line AA, FIG. 8 is a cross-sectional view taken along the line BB, and FIG. 9 is a cross-sectional view taken along the line AA in a state worn by the user. The illustrated slipper is for the right foot.

  The slipper 1 is composed of a lower bottom 10 whose upper surface is covered with a cushion 11 and a honey 12 that covers an instep of the foot, and the toe portion is divided into a fork by an inner toe portion 12a and an outer toe portion 12b. The material of the lower bottom 10 is preferably urethane or the like having flexibility and elasticity. The illustrated slipper 1 is a “hanging type” in which the cushion 11 is sewn in a shape of wrapping with a honey 12. It is also possible to use a “stitch” type. Both toe portions 12a and 12b have a bifurcated shape in which the toe portion of the lower base 10 is also composed of an inner toe portion 10a and an outer toe portion 10b. The third to fifth rods are inserted into the part 12b. In addition, as shown in the rear view of FIG. 6, the innermost end of the gap 13 forms a chord 14 in the toe portion of the honey 12. With this configuration, the second to fourth rods, which move only in a single state under normal conditions, move separately, especially the second and third rods, and the user is aware of each footpad. Inspired to do so, they will use nature and footpads actively.

  Further, as shown in FIGS. 4 and 7, a grounding piece 15 is affixed to the lower surface of the lower sole 10 at a location where the second foot of the sole and the middle foot joint joint of the third foot abut. . Therefore, as shown in FIGS. 8 and 9, when the slipper is worn, the lower base 10 is pushed up by the grounding piece 15, and the cushion 10 is raised vertically in the foot axis direction at a position corresponding to the grounding piece 15. Convex part 16 is constituted. The grounding piece 15 has an elliptical shape or a tear-like shape having a bowl-shaped cross section on the axis, and is preferably made of a urethane material that is harder than the cushion 10. With such a configuration, the middle foot joint joint of the base of the second heel and the third heel is pushed up by the convex portion 16 when worn, and therefore, as shown in FIG. And draw a gentle arch with the position of the crotch of the third heel. Moreover, between the 2nd collar and the 3rd collar is forcibly opened by the convex part 16 and the toe part made into the forked shape. This further promotes a state in which all the five fingers of the above-mentioned foot are actively used, and in particular, the fifth heel is more strongly pressed against the lower bottom surface.
