Respective distances of an outer periphery of at least one of the pair of rollers 2a and 2b from the shaft 1 are different from each other. The pair of rollers 2a and 2b assumes a non-exact-circle shape, and has the same size and shape. The states of attachment of them to the shaft 1 are also identical in phase to each other.SELECTED DRAWING: Figure 1

Description

The present invention relates to a health appliance using a roller.

It is known that conventional health appliances have disks attached to the left and right sides of the shaft. (See, for example, Reference 1.)

Utility Model Registration No. 319787

However, such instruments have a perfect circular shape on the left and right, and a shaft is attached to the center thereof. As a result, even if you try to push the shaft part with the sole of your foot, the resistance force is the same regardless of the position of rotation.

This poses an unsatisfactory issue for health appliances.

An object of the present invention is to provide a roller-type health device capable of effectively training muscles and the like in consideration of such conventional problems.

In order to achieve the above object, the first invention is a roller-type health appliance provided with a shaft and a pair of rollers fixed so as to face each other on the left and right sides thereof.
The pair of rollers is a roller-type health appliance characterized in that the outer circumference of at least one of the rollers has a different distance from the shaft.

In the second aspect of the present invention, the pair of rollers have a non-circular shape, have the same size and shape as each other, and are attached to the shaft in the same phase. It is a type health appliance.

A third invention is an exercise exercise method using the roller-type health device of the first or second invention.
By placing the soles of both feet on the shaft of the roller-type health device placed on the floor, or by bending and stretching the feet while keeping the feet open along the shaft and in contact with the inside of the left and right rollers. It is an exercise exercise method that trains and promotes health.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of the roller-type health appliance 10 according to the present embodiment, and FIG. 2 is a front view of the roller.

In FIGS. 1 and 2, 1 is a shaft, and 2a and 2b are rollers fixed to both left and right ends of the shaft 1.

The rollers 2a and 2b are egg-shaped as shown in the figure. In addition, a non-circular shape such as an elliptical shape or a rugby ball shape is desirable. Alternatively, if it is a perfect circle, the axis 1 is eccentric. Furthermore, the circumference may be polygonal. In short, the rollers 2a and 2b of the present invention are characterized in that the distances from the shaft 1 to the outer circumferences of the rollers 2a and 2b are different.

Further, the left and right rollers 2a and 2a in FIGS. 1 and 2 have the same size and shape, and the states fixed to the shaft 1 are in phase with each other. Therefore, when the health appliance 10 is placed on the floor, the heights on the left and right are always the same regardless of the position of the rotating state. Then, as the height of the shaft 1 rotates, it changes.

A silicon rubber guard is wrapped around the outer circumferences of the rollers 2a and 2a, and a groove is cut there to prevent slipping, and at the same time, there is an advantage that the floor is not damaged.

Further, the disk surface portion 2c is a transparent acrylic plate. Of course, it can be opaque. The shaft 1 is made of an iron pipe, but other materials such as plastic may be used.

By appropriately attaching weights such as hand pedals to the outside of each of the rollers 2a and 2a, it is possible to create more variations in how the load is applied during the bending and stretching exercises.

At that time, it is also possible to devise such as eccentricity of the mounting position.

Note that FIG. 9 is an example of one design data of the health appliance 10 according to the embodiment of the present invention.

Next, a method of using the health device 10 according to the present embodiment will be described.

In FIG. 3, with the person 5 lying on the floor 6, the hands 5a and the buttocks 5b are attached to the floor 6, only the feet 5c are floated, and the arch 5d1 of the toes 5d is placed on the axis 1, and the feet 5c are moved back and forth. The health appliance 10 is rolled back and forth by stretching and contracting it.

In the bending and stretching motion, since the rollers 2a and 2b are egg-shaped, the axis 1 on which the arch 5d1 rests also moves up and down according to the forward and backward movement. Therefore, the load applied to the muscles of the foot 5c changes, the trunk is strengthened, and blood circulation can be promoted by stimulating the soles of the feet. Furthermore, it can be expected to have an effect on the back surface such as the gluteus maximus and a hip-up effect.

Further, when returning the health device 10 to the front, it is necessary to pull the foot sole toward the front while bending it further downward, so that the muscles are further trained.

FIG. 4 shows a harder exercise. This is a method of performing bending and stretching exercises with the buttocks 5b floating from the floor 6 with the hands 5a. In this case, since the bending and stretching exercises are performed while supporting the weight with the hands 5a and the legs 5c, the trunk and muscular strength are further strengthened.

FIG. 5 shows a method of performing bending and stretching exercises with the hips 5e floating at the same time as the hips 5b. It will be a fairly hard exercise.

FIG. 6 shows a method of bending and stretching the legs 5c with the back 5f floating in addition to the hips 5b and the hips 5e. It will be an extremely hard exercise.

These exercise methods are exercises that utilize their own weight, and since the load can be controlled by changing their posture, they can cover a wide variety of exercises from the rehabilitation level of the elderly to the athlete level.

FIG. 7 is another method of using the health device 10 according to the embodiment of the present invention. In FIG. 7, 5d2 is the left and right side surfaces of the toe 5d. That is, the toes 5d of both feet 5c are opened along the axis 1, and the left and right side surfaces 5d2 are pushed so as to spread the inner side 2c1 of the disk surface portions 2c of the rollers 2a and 2a. Then, the health appliance 10 is lifted from the floor 6 with both toes 5c open.

In such a state, FIG. 7 shows a state in which the leg 5c is bent, and FIG. 8 shows a state in which the leg 5c is extended in such a state.

In this way, with the legs 5c open and the health equipment 10 lifted, the legs 5c are flexed and stretched, so the training of muscle strength such as the abdominal muscles becomes hard at last, and it is used for training the trunk and muscles. Become.

Although not shown, as a modified example, wrist, arm, and trunk training can be performed by using the device in a prone state.

According to the roller-type health device of the present invention, it has an effect of easily and effectively training muscles and the like, and is useful in homes and sports gyms.
