The present invention relates to a footwear insole suitable for use in recovering shoes.

(Prior Art) In recent years, with the development of transportation means and transportation networks, the walking distance of humans has been significantly reduced. As a result, the muscles of the legs are weakening, and the legs are prone to fatigue, and a slight impact during sports causes a fracture.

On the other hand, with the improvement of life, emphasis is placed on making healthy progress,
Many facilities such as sports gyms are also built. Various kinds of training equipment for training the body are installed in the gym so that not only athletes but also ordinary people can perform various trainings.

(Problems to be Solved by the Invention) However, although various devices for training the arms, legs and the like of the body have been conventionally provided, no device for training the toes has been known.

Therefore, in order to prevent the injuries of the toes and fractures of the toes during exercise and to prevent the deterioration of not only the fingers but also the entire feet, a device for positively strengthening the toes is needed. is there. Further, there is also a need for a device for people who have a toe damaged due to an accident, an illness or the like to restore the function of the finger.

The present invention has been made in view of the above-mentioned state of the art, and provides an insole for footwear that allows anyone to train their fingers anytime, anywhere.

(Means for Solving the Problems) The means of the present invention configured to solve the above-described problems is a front foot portion, an arch portion, and a heel foot portion that are integrally formed along the longitudinal direction, and the upper surface is a foot. An insole main body which is a contact surface, a laterally long exercise opening formed in the main body of the insole located on the entire end side of the front stepping portion, and a longitudinal direction of the fingertip pushing member in the exercise opening. The fingertip pushing member that is fitted so as to be displaceable in the direction and has a finger hook portion formed on the upper surface, and the pushing force that the fingertip pushing member receives toward the rear side in the longitudinal direction of the insole body. The restoring force applying member elastically supports the fingertip pushing member.

(Operation) With this configuration, the foot is put on the shoe or sandal, the fingertip is hung on the finger hanging portion of the fingertip pushing member to repeat the bending motion, and the fingertip pushing member resists the elastic force of the restoring force imparting member. By pushing it toward the rear of the main body of the insole, it is possible to strengthen not only the fingers but also the muscles of the entire foot.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

In the figure, reference numeral 1 designates a main body of an insole which is made of synthetic resin such as vinyl chloride or natural or synthetic leather and is slightly thicker than an ordinary insole. The foot 1A, the middle arch 1B and the rear heel 1C are integrally formed, and the upper surface 1D is a flat foot contact surface and the lower surface 1E is a foot contact surface. .

The insole body 2 is located near the tip of the front stepping portion 1A.
Is an exercise opening formed penetrating the foot contact surface 1D and the foot contact surface 1E, and the exercise opening 2 is a curved front contact surface formed along the tip edge of the insole body 1. 2A and a linear rear contact surface 2 connected to both ends of the front contact surface 2A.
B and B form a substantially semi-elliptical plane.

Reference numeral 3 denotes an elastic stretchable sheet material such as a rubber sheet. The elastic stretchable sheet material 3 is formed in the same outer shape as the insole body 1, and the flat upper surface thereof is the lower surface 1 of the insole body 1.
It becomes an abutting surface 3A with E, and the lower surface becomes an abutting surface 3B with footwear such as shoes and sandals. The elastic stretchable sheet material 3 abuts the lower surface 1E of the insole body 1 so as to close the exercise opening 2, and the outer peripheral edge thereof is sewn with the thread 4 interposed therebetween.

Reference numeral 5 denotes a fingertip pushing member made of synthetic resin or leather like the insole body 1, and the fingertip pushing member 5 is a front contact surface having the same curved surface as the front contact surface 2A of the exercise opening 2. 5A
And a rear contact surface 5B that is parallel to the rear contact surface 2B, and an upper surface 5C and a lower surface 5D that are flush with the upper surface 1D and the lower surface 1E of the insole body 1 to form a substantially semi-elliptical plate. And five finger-holding recesses 6 located on the rear side contact surface 5B and capable of hanging five fingers on the upper surface 5C.
A, 6B, 6C, 6D, and 6E are formed (hereinafter collectively referred to as finger-holding recesses 6).

Then, the fingertip pushing member 5 having the above-described configuration is fitted into the exercise opening 2 in a state where the front contact surface 5A is in contact with the front contact surface 2A, and the lower surface 5D thereof is the elastic stretchable sheet material 3.
Is bonded to the upper abutting surface 3A. Thus, a space S having a distance is provided between the rear contact surface 5B and the rear contact surface 2B, and the fingertip pushing member 5 has this space S.
It is adapted to be displaced in the directions indicated by arrows A and B inside.

The insole according to this embodiment is constructed as described above, and in use, the insole is laid on the inner bottom of the shoe or sandal in advance. Then, every time the user wears shoes or sandals, all the fingers C are bent with the finger resting recesses 6 kept folded, and the rear contact surface 5B of the fingertip pushing member 5 is the rear contact surface of the exercise opening 2. 2 Touch the fingertip pushing member 5 until it hits A.
Push it in the direction by a distance. As a result, the outer peripheral portion of the front contact surface 5A of the fingertip pushing member 5 of the elastic stretchable sheet material 3 receives the tensile force, and the rear portion of the rear contact surface 5B receives the compressive force. Then, the reaction force of the pulling force and the compressing force is applied to each finger C via the fingertip pushing member 5, so that the muscle force of the finger C is strengthened.

When the rear contact surface 5B hits the rear contact surface 2B as described above, the force of the finger C is released. Then, the fingertip pushing member 5 returns in the direction of the arrow B by the restoring force of the elastic stretchable sheet material 3, and the front contact surface 5A of the fingertip pushing member 5 contacts the front contact surface 2A of the exercise opening 2. Then, the finger C is pushed again to push the fingertip pushing member 5 in the A direction.

In this way, by constantly repeating the bending and extension of the finger C, the movement of the finger joint can be made smooth, and the muscles of the finger as well as the instep and shin can be strengthened. Further, according to the present embodiment, when the fingertip pushing member 5 is pushed most in the direction of arrow A, the rear contact surface 5B abuts the rear contact surface 2B, and the user's momentum The user can get a sense of fulfillment because he / she is able to know exactly, and will not get tired even if he / she trains for a long time.

Further, since the above-described movement of the finger C can be performed while standing or sitting on a chair, the user can perform training at any time regardless of the place and time. Moreover, since the movement of the finger C is not touched by the shoes or slippers, it is possible for a person who is conscious of the eyes of others to train without hesitation.

Furthermore, when the finger C is bent and stretched, the instep and arch of the foot also expand and contract, so it can be used to exercise the entire foot.
Is also stimulated, which has the synergistic effect of training the entire foot.

Moreover, the rising portion of the finger hanging concave portion 6 is fitted into the back concave portion of the base of the finger. Therefore, when the user walks while wearing the insole of this embodiment, the rising part of the plate does not come into pressure contact with the sole of the foot, so that the user can walk normally without any trouble. As a modification of this embodiment, as shown in FIG. 6, the upper surface 5'C of the fingertip pushing member 5'is provided.
The finger-holding recess 6'may be formed in the. Furthermore, the upper surface 5 '
A plurality of corrugated irregularities may be formed on C, or irregularities may be formed in a file having a coarse mesh. The point is that it is a finger-holding portion capable of pushing the fingertip pushing member 5 in the arrow A direction.

Further, in this embodiment, the elastic stretchable sheet material 3 is used as the returning means of the fingertip pushing member 5, but for example, the exercise opening 2 is used.
A metal or synthetic resin spring member is interposed between the insole body 1 and the fingertip pushing member 5 so that the fingertip pushing member 5 is always biased in the direction of arrow B. Can be configured as
A resilient biasing member may be interposed between the insole body 1 and the fingertip pushing member 5.

Further, a counter that counts when the fingertip pushing member 5 hits the rear contact surface 2B may be provided upward on the arch portion of the insole body 1 so that the actual number of movements can be measured.

(Effects of the Invention) The present invention is as described above in detail, and by bending and stretching the finger hooked on the finger-holding portion of the fingertip pushing member, the fingertip pushing member is resisted against the elastic force of the restoring force applying member. Since it is configured to be pushed, it is possible to easily perform muscle strengthening of the entire foot such as the instep and shin, joint motion, and function recovery motion as well as muscle strength of the finger at any time and anywhere.
