Description

  The present invention relates to footwear, and is intended to improve physical strength, improve balance, and promote health by strengthening and training the muscles of legs and legs that are not normally used.

Technical background

  Conventionally, various proposals have been made to improve footwear for the purpose of enhancing the muscle strength of the legs and legs and improving health. For example, in order to increase the strength of the legs and hips, there was a method of training by wearing shoes and clogs with weights (ballasts) for special purposes (karate, judo, etc.) It is not intended to increase muscle strength.

  However, with the recent increase in health consciousness, the idea to increase the muscles of the legs and hips has been born for the general public who is strikingly lacking exercise, and in particular, it is required to prevent the weakness of the legs and legs of the elderly. I came. Originally, even if it is a healthy young ordinary person, if the muscles are placed in a situation where they are not used at all, the muscle strength will be noticeably reduced in 3 to 4 days, and going out will be less like the elderly and heavy. When there are fewer opportunities to hold things, the deterioration of the legs will progress significantly.

  In order to improve this, the present inventor has already made the following proposal.

Utility model literature

Utility model registration No. 3063385. This device adopts a semi-elliptical spherical shape with a convex curved surface (the top part is about 40 mm in height from the bottom of the foot) as the bottom structure of the slipper, and the unstable state of rolling and pitching when worn. It creates and thus stimulates and strengthens the muscles that work to keep this instability stable. These muscles are part of the adductor and large buttocks of the foot and are rarely used in general walking.

Utility model literature

Utility model registration size 3063893. This device also relates to a slipper. The difference from the above device is that the bottom structure has a mountain shape in a side view instead of a semi-elliptical spherical shape. It is the one that strengthened.

  As mentioned above, the slippers that improve the muscle strength of the legs and the hips, and improve the balance sensation, can generally achieve the intended purpose by the bottom structure that becomes the convex curved surface. Moreover, when the effect by actual use was verified, the result that there was little real effect came out.

  Therefore, as a result of detailed research, as the action of this slipper, in view of creating an unstable state of rolling and pitching, that is, creating a dangerous state, the shape of the convex curved surface (the topmost part is from the bottom of the foot). As a result of making the height (about 40 mm) gentle, the muscular strength to correct the unstable state of rolling and pitching can be reduced, and there is an advantage of avoiding the risk of falling or ankle sprain as much as possible. The effect of strengthening muscular strength was inferior.

Furthermore, it has a convex curved bottom structure, but the extension line of the vertex position of the convex curved surface, that is, the ridge line is not along the center line of the curved foot (virtual movement locus of the center of gravity), and rolling and pitching are not performed. There was also a problem that smooth instability correction could not be expected because it did not follow the natural movement of the foot.
Accordingly, there is a need to be able to sufficiently avoid the danger of falls or ankle sprain while being able to sufficiently stimulate the muscles of the foot adductor and large buttocks that are rarely used in general walking. .

  In order to solve such a problem, the footwear according to the present invention is a footwear having a bottom surface structure having a convex curved surface, and the convex curved surface has a ridge line 3 along a virtual curve 4 passing through the center of the foot bottom 1A. And the top 2 of the convex curved surface is 45 mm to 60 mm from the foot bottom 1A of the footwear 1, and is located at approximately one third of the front side of the foot bottom 1A in the longitudinal direction. The ridgeline 3 is downwardly inclined with a predetermined convex curved surface from the top 2 to the toe side, the little finger side, and the thumb side, and the heel-corresponding portion 5 of the convex curved surface is 20 mm or more from the foot bottom 1A. 30 mm or less, the ridgeline 3 is inclined downward for a while from the top 2 to the heel-corresponding part 5, and is downwardly inclined with a predetermined convex curve toward both sides of the foot. It is a measure taken.

  As an effect of the present invention, the top surface 2 of the convex curved surface is positioned at a position approximately one third of the front side in the longitudinal direction as compared with the conventional bottom structure of the convex curved surface, and the foot-shaped bottom surface of the footwear 1 From 1A to 45 mm to 60 mm, the ridge-corresponding portion 5 of the convex curved surface becomes a large convex curved surface of 20 mm to 30 mm from the bottom surface 1A of the foot shape, and the slope of the curved surface becomes a steep slope as a whole. Pitching action can be expected, and as a result, it is possible to extract sufficient muscle strength stimulation that is opposite to this rolling and pitching, and as a result, extreme inner crotch walking, crotch walking correction, foot curvature correction, etc. I can plan.

  Further, since the convex curved surface has a virtual curve 4 passing through the center of the foot bottom 1A, that is, the ridge line 3 along the center of gravity movement locus, when the footwear is grounded, the convex curved surface is always When the apex, that is, the ridgeline 3 comes into contact, pitching along the inclined ridgeline 3 occurs naturally, and muscle stimulation that causes an action to correct this is smoothly guided. In addition, when working to correct the above-described large inclination, the sense of balance is naturally stimulated, and therefore, the sense of balance can be avoided before it is lost.

  In the present invention, the numerical values of the heights of the topmost portion 2 and the heel-corresponding portion 5 of the convex curved surface are specified as important requirements, but for the effect, the slipper length size (26 cm) is specified. It has little to do with the slight change in the size, and is related to the height of the convex curved surface of the component that produces the rolling and pitching action, so it is sufficient even if there is no numerical specification of the length size of the slipper It has meaning.

In the present invention, it is preferable that the footwear is a slipper and the bottom structure is formed integrally with the slipper. The footwear may be a shoe, and the bottom structure may be configured integrally with the shoe.
Furthermore, the footwear may be a shoe, the bottom structure may be configured separately from the shoe, and may be configured to be detachable from the bottom of the shoe by the attachment means 6.

It is preferable that a notch of a predetermined pattern generally used as a slip stopper is formed on the convex curved surface of these footwear.
As a material, natural rubber is most preferable, but any material can be used as long as it is already used as a shoe sole such as slippers and sneakers, such as urethane and synthetic rubber.

  As shown in FIG. 1 to FIG. 3, in the first embodiment, the footwear of the present invention is a slipper generally worn indoors, and its bottom structure is integrally formed with the slipper main body (the top ridge 7? Existing side). An embodiment applied to the slipper as described above will be described. This slipper is of a general size (length 26 cm) and has a bottom structure made of natural rubber having a convex curved surface. The convex curved surface has a ridge line 3 (FIG. 2) along a virtual curve 4 passing through the center of the foot-shaped bottom surface 1A shown in FIG. 1, and the topmost portion 2 of the convex curved surface is the footwear 1 as shown in FIG. It is about 54 mm from the bottom surface 1A of the foot shape, and is located on the front side of the longitudinal center P1 of the bottom surface 1A of the foot shape, here, approximately 1/3 of the front side.

  Then, as shown in FIG. 2, the ridgeline 3 is downwardly inclined with a predetermined convex curved surface (explained with the bottom surface facing upward) from the top 2 of the convex curved surface toward the toe side, the little finger side, and the thumb side. As shown in FIG. 3, the heel-corresponding portion 5 of the convex curved surface has a center at a position of 40 mm from the rear end portion of the heel, where the height is about 25 mm from the bottom surface 1A of the foot, and the ridgeline 3 is inclined downward for a while toward the heel-corresponding part 5 from the top 2 and is inclined downward with a predetermined convex curve for a while toward both sides of the foot.

The convex curved surface is engraved with a predetermined pattern provided in a general slipper, sneaker or the like as a slip stopper. Furthermore, small innumerable protrusions for acupoint stimulation are provided on the upper surface of the slipper (where the foot is placed).
The object of the present invention can be achieved without providing such indentations and protrusions. In addition, the umbilical cord 7 uses a bridge type in which a finger comes out on the tip side, but may be configured to cover all the fingertips.

Second embodiment

  In this embodiment, the footwear of the present invention is applied to general athletic shoes (substantially the same as sneakers). In this embodiment, basically, the bottom surface structure of the first embodiment is used as it is, and repeated explanation is omitted, but the differences are as follows.

As shown in FIG. 4, the footwear is an athletic shoe, the bottom structure is configured separately from the shoe, and is attached to the bottom of the athletic shoe by attachment means 6, here, an attachment belt having a magic fastener. It is configured to be detachable. The base end portion of the magic fastener is fixed to the bottom structure side.
As described above, since the bottom surface structure is detachable, the spacer 8 can be interposed between the bottom surface of the athletic shoe and the bottom surface structure. The height of the curved surface can be adjusted.

Therefore, as the original shape of the bottom surface structure of this embodiment, the top 2 of the convex curved surface described in the first embodiment is about 45 mm from the foot bottom 1A of the footwear 1, and the heel corresponding portion 5 of the convex curved surface is The center is located at a position 40 mm from the rear end of the heel, where the height is about 20 mm from the foot bottom 1A, and the spacer can be increased or decreased as appropriate for height adjustment. .
Of course, as such an athletic shoe, the bottom surface structure of the convex curved surface of the present invention may be integrally provided from the beginning.

Industrial application fields

As an example of use of the present invention, it is considered as indoor footwear such as slippers, sandals, etc., but in this sense, patients who are used for training of the legs and legs of healthy elderly people in each home, etc. It can also be used in hospitals.
On the other hand, since it can be applied to athletic shoes, such athletic shoes have the advantage of being able to stimulate special muscles of the legs and legs. For example, if used as boxing shoes, the punching operation can be practiced while maintaining a sense of balance. A method of use is also born, and it can be expected to be used as an exercise aid for various competitions.
