SUMMERY OF THE UTILITY MODEL

Technical problem to be solved by the utility model

However, the healthy sandals described have the following points to be improved. In a healthy sandal, the sandal 1 needs to have a considerable stiffness in order to support the attached stimulation nails 2. On the other hand, if the sandal 1 is hardened, the sandal 1 has points to be improved such as being unable to bend, being difficult to walk, and being easy to fatigue.

Therefore, an object of the present invention is to provide a sandal that is easy to walk and can efficiently apply appropriate stimulation to the sole.

Effect of the utility model

The sandal of the utility model is a sandal which is provided with a sole part and a pad part and is formed by specified resin materials, and is characterized in that,

the shoe bottom has:

a ball of thumb opening formed as an opening penetrating from the insole support surface in contact with the back surface of the insole part to the sole surface in contact with the ground;

a heel opening part formed as an opening penetrating to the sole surface contacting with the ground,

the shoe pad portion has:

a toe pressure protrusion formed on a surface of the pad section;

a ball of thumb protrusion formed in a direction protruding from a rear surface at a position corresponding to a ball of foot vicinity area arranged on the toe pressure protrusion, and fitted to the ball of thumb opening;

and a heel protrusion portion formed in a protruding direction from the rear surface at a position corresponding to a region near the heel of the foot disposed on the toe press-out portion, the heel protrusion portion being fitted to the heel opening portion.

Thus, at the beginning of a walking motion in which the heel is grounded and at the end of a walking motion in which the ground is kicked with the ball of the foot, the reaction force from the ground is efficiently transmitted to the toe-pressing protrusion without being absorbed by the sole portion. Further, the pressure can be applied to the sole of the human foot efficiently.

In the sandals of the utility model, it is characterized in that,

the cushion part is formed of the resin material having a lower elasticity than the sole part.

Thus, the insole portion is formed to be lower in elastic force, i.e., harder than the sole portion, and therefore, the reaction force from the ground is efficiently transmitted to the toe-press convex portion without being absorbed by the sole portion. Further, the pressure can be applied to the sole of the human foot efficiently.

In the sandals of the utility model, it is characterized in that,

the sole portion and/or the cushion portion are formed using an ethylene vinyl acetate copolymer resin.

This allows efficient transmission to the toe press-convex portion without interfering with walking. Further, the walking is facilitated, and the pressure can be efficiently applied to the sole of the human foot.

Detailed Description

[ example 1 ]

Hereinafter, the sandal 100 of the present invention will be described as an example. The sandal 100 is molded from a lightweight and soft resin material, for example, a resin containing an EVA (ethylene vinyl acetate copolymer) resin as a main component.

Constitution of the No. 1 sandal 100

As shown in fig. 1, the sandal 100 has a sole portion 101, a vamp portion 103, a footbed portion 105, and a strap portion 107.

1. Shoe bottom 101

Fig. 2 shows a state where the cushion part 105 is detached from the sandal 100 for right foot. The sole portion 101 is located between the cushion portion 105 and the ground. The shoe bottom 101 is formed of a lightweight and soft resin material. The sole 101 includes a cushioning portion 101a and a side wall portion 101 b.

The cushioning portion 101a functions as a sole. Cushioning portion 101a has sole surface S11 (see fig. 5), insole support surface S13, ball of foot opening portion H11, and heel opening portion H13.

The sole surface S11 contacts the ground. The insole support surface S13 contacts the back surface S53 (see fig. 4) of the insole portion 105, and supports the cushion portion 105.

The ball foot opening H11 is formed as an opening penetrating from the insole support surface S13 to the sole surface S11. Ball of thumb opening H11 is fitted into ball of thumb P51 (described later) formed in insole portion 105.

The heel opening H13 is formed as an opening penetrating from the insole support surface S13 to the sole surface S11. Heel opening H13 is fitted into heel protrusion P53 (described later) formed in insole portion 105.

The side wall portion 101b is formed along the outer periphery of the buffer portion 101 a. The side wall portion 101b forms a shoe pad arrangement space R101 together with the shoe pad support surface S13. A cushion part 105 is disposed in the insole disposition space R101.

2. Shoe upper part 103

Returning to fig. 1, the upper part 103 connects one side edge of the shoe bottom 101 with the other side edge in an arch shape. The upper part 103 is disposed along the instep when in use.

3. Cushion part 105

As shown in fig. 1, the insole portion 105 is disposed on the sole portion 101 and contacts the sole surface of the user. The cushion part 105 is formed of a lightweight and soft resin material, and is formed of a resin material having a lower elastic force than the sole part 101, particularly the cushioning part 101 a. That is, the insole portion 105 is formed to be harder than the sole portion 101.

Fig. 3 shows a perspective view of the insole portion 105 for the right foot. The cushion part 105 has a front surface S51, a back surface S53 (see fig. 4), a ball of thumb convex part P51, a heel convex part P53, and a toe pressure convex part P55.

Fig. 4 shows a state in which the cushion part 105 is viewed from the back surface S53. The ball of thumb protrusion P51 is formed to protrude from the back surface S53 at a position corresponding to an area near the ball of the foot disposed on the toe press protrusion P55 formed on the surface S51. Ball of thumb P51 has a vertically long rectangular parallelepiped shape from the toe side toward the heel side. Further, the ball of thumb P51 is formed to spread toward the direction protruding from the back surface S53.

The heel protrusion P53 is formed to protrude from the back surface S53 at a position corresponding to a region near the center of the heel of the foot arranged on the toe press-protrusion P55 formed on the surface S51. Heel protrusion P53 has a rectangular parallelepiped shape. Similarly to the ball of thumb protrusion P51, heel protrusion P53 is formed to expand in the direction of protruding from rear surface S53.

Fig. 5 shows a state where ball convex part P51 and heel convex part P53 are fitted to ball opening H11 and heel opening H13 of cushioning part 101a, respectively, as viewed from sole surface S11 side. Since ball of thumb P51 is fitted into ball of thumb opening H11 and heel protrusion P53 is fitted into heel opening H13, cushion part 105 and cushion part 101a are integrated, and cushion part 105 is prevented from being displaced with respect to cushion part 101 a.

Ball of thumb protrusion P51 has a ball of thumb sole surface S55 and heel protrusion P53 has a heel sole surface S57. In a state where ball convex part P51 and heel convex part P53 are fitted to ball opening H11 and heel opening H13 of cushioning part 101a, respectively, heel convex part P53 arranges ball sole surface S55 in the same plane as sole surface S11 of cushioning part 101 a. That is, the sole surface of sandal 100 is formed by ball toe sole surface S55 of ball toe convex portion P51, heel sole surface S57 of heel convex portion P53, and sole surface S11 of cushioning portion 101 a.

The person performs a walking motion of initially landing the ground from the heel and finally kicking the ground with the ball of the thumb. The person walking with the sandal 100 touches the ground from the vicinity of the heel sole surface S57 at the very beginning of the walking motion. At this time, the reaction force of the force applied by the person to the ground surface is transmitted from the ground surface to heel convex portion P53 and further to toe convex portion P55 via heel sole surface S57. This enables the toe pressure protrusion portion P55 to efficiently apply pressure to the sole of the human foot.

Further, since heel protrusion P53 is formed to be lower in elasticity, i.e., harder than cushioning portion 101a, the reaction force from the ground is not absorbed by cushioning portion 101a and is efficiently transmitted to toe press-out portion P55. Further, the pressure can be applied to the sole of the human foot efficiently.

Further, the person walking with the sandal 100 kicks the ground near the hallux sole surface S55 at the end of the walking movement. At this time, the reaction force of the force applied by the person to the ground surface is transmitted from the ground surface to the ball toe convex portion P51 and further to the toe pressure convex portion P55 via the ball toe sole surface S55. This enables the toe pressure protrusion portion P55 to efficiently apply pressure to the sole of the human foot.

Further, since the cushion part 105 is formed to be lower, i.e., harder than the elastic force of the cushioning part 101a, the reaction force from the ground is not absorbed by the cushioning part 101a, and is efficiently transmitted to the toe press-out part P55. Further, the pressure can be applied to the sole of the human foot efficiently.

Fig. 6 shows the arrangement of the toe-pressing portion P55 formed on the surface S51 of the insole portion 105. The toe pressure protrusion portion P55 is formed to correspond to the position of the acupuncture point of the sole. Thereby, the acupuncture points of the sole can be properly pressed. Further, the toe squeeze portion P55 has a shape capable of memorizing the part of the body stimulated by the acupuncture point of the sole. Further, a smaller hemispherical protrusion is formed on the surface of the toe-embossed portion P55. This prevents the sole from slipping and increases the pressing force on the sole.

4. The belt part 107

The belt portion 107 is formed in an arch shape in the upper part 103 from the vicinity of the boundary of the cushioning portions 101a on the inner side and the outer side, respectively. The belt portion 107 is hooked on the heel of the user to fix the user's foot at a predetermined position on the cushion portion 105.
