Description

The present invention relates to footwear, and more particularly to footwear that can stimulate the acupoints of the soles by wearing them.
In the present invention, the “point” on the sole includes a so-called “reflection zone”.

  Conventionally, various footwear such as shoes, slippers, sandals and the like having a sole pressure stimulation function have been devised and put into practical use.

  As this type of footwear, one having a large number of small protrusions formed over almost the entire upper surface of the midsole is known. This footwear is often found in indoor footwear such as slippers.

  In addition to the above, footwear in which a magnet is disposed at a position corresponding to a sole point on the upper surface of the midsole and an elastic body such as a sponge is disposed around the magnet has been conventionally known (for example, the following) Patent Document 1).

  In the case of the former footwear, when this is worn, the pressure points on the soles are pressed and stimulated by the small protrusions, thereby bringing about a health promotion effect such as blood circulation promotion, but on the other hand, the small protrusions directly hit the soles, I sometimes felt discomfort and pain in my soles.

In the case of the latter footwear, when worn, the acupoints on the sole are stimulated by the magnetic field lines coming out of the magnet, thereby bringing about effects such as blood circulation promotion. In addition, the impact of the magnet on the sole is somewhat relaxed by the elastic body disposed around the magnet.
However, in the case of this footwear, since the magnet has a flat upper surface such as a disk shape or a square shape and has a large area, a direct acupoint stimulating effect by stepping on a protrusion like the former footwear can be almost expected. In addition, it was difficult to effectively stimulate the acupuncture points of the soles with only the magnetic field lines coming out of the magnets. In addition, even though an elastic body is arranged around the magnet, a hard magnet directly hits the sole of the foot, so it was still not sufficient in terms of comfort.
Japanese Utility Model Publication No. 61-160702

  An object of the present invention is to provide footwear that can effectively stimulate the acupoints on the soles of the feet and that can provide extremely excellent comfort.

  The footwear according to the present invention has at least one sole acupuncture point stimulating projection provided at a location corresponding to the sole acupoint on the upper surface of the midsole, and the same number of cushion materials as the projection having a dome-shaped top surface shape. It is characterized in that it is joined to the upper surface of the midsole so that the protrusion is located below the top.

In the above footwear, when wearing this, the points on the sole of the foot are pressed by the projection having a small cross-sectional area located below the top of the cushion material while the force due to the weight and walking load is dispersed by the cushion material. The
Therefore, according to the footwear of the present invention, the point on the sole can be effectively stimulated by the protrusion, and the cushion material having the dome-shaped top surface can be applied to the sole while avoiding the concentration of force on the protrusion. Because it fits, you can get a very comfortable comfort without feeling discomfort and pain on the soles.

  In the footwear according to the present invention, the protrusion may be formed by arranging and fixing the protrusion forming member at a position corresponding to the sole of the sole on the upper surface of the midsole.

  In the above case, the number and position of the protrusions can be arbitrarily and easily set according to the shape of the insole and the like, and is particularly suitable for small-scale production.

  In the above case, it is preferable that the protrusion forming member includes a disk-shaped base portion and an upward convex portion rising from the center portion of the base portion.

If the protrusion forming member has the above-described structure, it can be stably arranged and fixed on the upper surface of the midsole due to the presence of the base portion.
The shape of the upper convex portion is not particularly limited, but the smaller the cross-sectional area of the tip portion, the higher the effect of stimulating the sole of the foot can be expected. Preferably, the upper convex portion is formed in a mountain shape such that the cross-sectional area gradually decreases toward the distal end portion in consideration of the foot acupuncture stimulation effect and stability / strength.
The material of the protrusion-forming member is not particularly limited as long as it is harder than the material of the cushion material and has a hardness that can press and stimulate the sole of the foot. However, for example, rubber, thermoplastic resin such as TR or PVC A magnet or the like can be used.
The protrusion forming member is usually accommodated in a recess formed in a lower portion of the top portion on the lower surface of the cushion material.

  Further, in the footwear according to the present invention, the protrusion may be formed by integrally forming an upper convex portion at a position corresponding to a sole point on the insole.

  In this case, since the protrusion is formed by the upper convex portion integrally formed on the insole, the manufacturing process can be reduced by that amount, and the manufacturing cost can be suppressed, so that it is particularly suitable for mass production. The insole provided integrally with the upper convex portion only needs to be formed of a material harder than the material of the cushioning material, but is usually formed of PVC or the like.

  The material of the cushion material is not particularly limited as long as it has rubber elasticity. For example, a foam such as latex, polyurethane, EVA or the like can be used. Moreover, it is also possible for the cushioning material to have two or more layer structures different in material and hardness. The cushion material only needs to have a dome shape (a mountain shape that draws a gentle curve when viewed from the side), and the planar shape may be an ellipse, an oval, or the like in addition to a circle. Although the lower surface of the cushion material is flat, as described above, the protrusion receiving recess is usually formed in the portion located below the top.

  In the footwear according to the present invention, the protrusion may have a hollow portion inside.

  In this case, when force due to weight or walking load is applied, the protrusion is slightly elastically deformed due to the presence of the cavity, thereby further reducing the contact of the protrusion against the sole and improving the comfort. Of course, the protrusion may be a solid one having no cavity.

  In the footwear according to the present invention, the upper surface of the midsole including the cushion material may be covered with the upper surface covering material.

In the above case, the cushion material is covered with the upper surface covering material, so that the appearance is good and the design as footwear is not impaired.
The material of the upper surface covering material may be appropriately selected from known materials that are usually used for covering the upper surface of the midsole. Since there is a possibility that the cushioning effect by the cushion material is not sufficiently exhibited, it is necessary to consider this point.

  1 to 4 show a first embodiment of the present invention. In this embodiment, the present invention is applied to sandals.

  As shown in FIGS. 1 and 2, the sandal (1) according to the present invention has five sole acupuncture stimulating projections (3) provided at five sole points corresponding to the upper surface of the midsole (2). In addition, the same number of five cushion materials (4) as the protrusions (3) having a dome-shaped upper surface shape are formed on the upper surface of the midsole (2) so that the protrusions (3) are located below the tops of these. It is what is joined.

  Projection (3) is the center of the heel of the sole (= insomnia), slightly behind the arch on the centerline of the sole, slightly forward of the arch on the centerline of the sole A part that can be indented (= spring), a part between the base of the second finger and the base of the third finger (= back inner yard), and a base of the third finger and the fourth part of the foot It is provided on the upper surface of the midsole (2) so as to correspond to the portion between the base of the finger (see FIG. 1).

Each protrusion (3) is formed by arranging and fixing the protrusion forming member (30) at a position corresponding to the sole point on the upper surface of the midsole (2).
The protrusion forming member (30) is made of PVC, and as shown in detail in FIG. 3, a flat base portion (31) and an upper convex portion (32) rising from the central portion of the base portion (31) Is integrated. The base portion (31) has a disk shape and has a cross-sectional shape such that the thickness gradually increases toward the upper surface side from the peripheral portion toward the central portion. The upward convex portion (32) has a relatively steep mountain-shaped cross-sectional shape with a rounded tip.

  The cushion material (4) is made of latex foam, has a gentle mountain-shaped cross-sectional shape, and has a substantially circular planar shape. As shown in FIGS. 2 and 3, a recess (41) for accommodating the protrusion forming member (30) is formed on the lower surface of the cushion material (4). The cushion material (4) is usually bonded to the upper surface of the midsole (2) with an adhesive.

  The insole (2) includes a PVC insole body (21) and a paperboard insole core (22) joined to the lower surface of the insole body (21). On the upper surface of the insole body (21), a gentle mountain-shaped ridge (211) is integrally formed at a portion corresponding to the arch on the center line in the sole. The raised portion (211) has a substantially oval planar shape along the sole.

  The upper surface of the midsole (2) including the cushion material (4) is covered with the upper surface covering material (5). The upper surface covering material (5) is made of synthetic resin or cloth, and as shown in FIG. 2, its peripheral edge is folded downward and joined to the peripheral surface of the midsole (2).

  The midsole (2) is joined to the upper surface of the main bottom (6). The outsole (6) includes an outsole body (61) made of EVA foam, and a wooden heel core (62) embedded in a collar portion of the outsole body (61). A rubber or synthetic resin grounding bottom (7) is joined to the lower surface of the main bottom (6). The peripheral surface of the insole (2) and the peripheral surface of the main base (6) are covered with the peripheral surface covering material (8). Thus, the bottom (10) of the sandal (1) is configured.

  Further, the sandal (1) includes two front and rear front bands (9A) and (9B), and a rear band (9C) having both ends connected to the rear front band (9B). Although not shown in detail, the two front bands (9A) and (9B) are attached to the bottom (10) by sandwiching both ends between the midsole (2) and the bottom (6). It has been.

  In the above sandals (1), when worn, the cushion material (4) disperses the force due to weight and walking load, while the projection (3) located below the top of the cushion material (4) The acupuncture points are pressed. Therefore, according to the above sandals (1), the protrusion (3) having a small cross-sectional area at the tip can effectively press and stimulate the acupoints of the sole, and the cushion material having a dome-shaped top surface shape ( 4) fits to the sole while avoiding concentration of force on the protrusion (3), so that a very comfortable fit can be obtained without feeling uncomfortable or painful on the sole.

  Further, in the case of the above sandals (1), since the protrusion (3) is formed by arranging and fixing the protrusion forming member (30) at a position corresponding to the sole of the sole on the upper surface of the insole (2), It is easy to adjust the number and position of the protrusions (3) according to the shape of (2) and the like, and is particularly suitable for small-scale production.

  FIG. 4 shows a modification of the sole acupuncture stimulating projection. The protrusion (3) in FIG. 4 has a hollow portion (3a) therein. The protrusion (3) is formed by the upper protrusion (32) of the protrusion forming member (30) as in the case of the protrusion (3) of FIGS. It has a hollow shape opened at the center of the lower surface of the part (31).

  If the protrusion (3) has a cavity (3a) as shown in FIG. 4, when the weight or walking load force is applied to the protrusion (3), it is slightly elastic due to the presence of the cavity (3a). Deformation, thereby reducing the contact of the protrusion (3) to the sole, further improving the comfort.
