Description

The present invention relates to a device for massaging a sole.

There are various shapes of foot massage devices, and if you divide them from usage, you can move your foot up and down and step on the foot of the massage device, or put the foot on the ring through the shaft, Move the foot back and forth to roll the shaft and wheel. There is a prior patent application that attaches wheels to both ends of the shaft and rolls the foot on the middle.

JP 2001-070386 A

A foot massage device that moves the foot up and down and has a footstep has a small angle of movement of the knee joint. If you raise your thigh and step on it, the movement angle will increase, but if you increase the number of massages, you will get tired, so people without physical strength will not be able to increase the number.

A foot massage device that moves the foot back and forth. The massage device massages the sole while maintaining a certain position on the floor. An object with a single axis can only move the length of the sole. Since the position does not shift, the operating angle of the knee joint becomes small. In addition, because the length of the part on which the foot is placed is long, such as the abacus, the multi-axis product with many shafts and rings passing through the shaft is long, so the state where the sole does not come off from the massage device becomes long. The length of the foot + the maximum length of the sole can be moved with respect to the floor, but because there are many parts where the sole touches the massage device, the pressure on the sole is reduced and massage stimulation Decrease. When there are many shafts and rings, there are disadvantages such as taking up space for storage and increasing production costs.

In the prior application with wheels on both ends of the shaft, the ratio of the diameter of the part on which the foot is placed and the wheel is close to 1: 1, so the sole is almost twice the contact point between the sole and the shaft has moved. Only the length (when the ratio is 1: 1, the axis rolls on the floor twice as long as the sole is moved), so the previous application has the effect of moving the joint. I haven't mentioned about it. However, there is little effect, but it is. In addition, since the shaft and the wheel are concentric in the side surface shape, there is no vertical movement of the center of gravity when rolling, and it is difficult to stop when rolling, so that there is a disadvantage that it is far away from the user.

The object of the present invention is to solve the disadvantages of the conventional products, and for a person without physical fitness to exercise to move the knee joint greatly without reducing the number of massages on the soles and the stimulation of the massage, the structure is simple It is to provide an inexpensive “massage that moves joints greatly”. Hereinafter, in order to distinguish the product of the present invention from the conventional product, the product of the present invention is referred to as a massage device, and the conventional product is referred to as a massage device as described above.

Provide flanges on both sides of the shaft with many protrusions that massage the soles. The collar is provided so that there is a difference in the length from the center of the shaft to the outer periphery of the collar, such as by rounding the corners of an ellipse or polygon, or by decentering a circular collar with the shaft. The center of the collar is shifted from the center of the massager by hollowing out a part of the collar, missing a part, and attaching a weight to the part. The collar is integrated with the shaft, or the collar and the shaft are separated, and a pin, key, rubber ring, etc. that stops the collar is attached to the shaft so that the shaft and collar rotate simultaneously, and the collar is removed. So that it can be replaced with another shape.

Rubber is provided on the outer periphery of the collar for the purpose of preventing slipping, protecting the floor, and soundproofing. Alternatively, the flange is made of rubber, and the collar is provided with these functions, such as making the periphery of the flange uneven.

When the foot is moved on the shaft and the shaft is rotated once, the “movement distance of the contact point between the sole and the shaft (including protrusions)” and the “movement distance of the contact point between the floor and the collar (including rubber ring)” The ratio is the same as the ratio of “the circumference of the shaft” and “the circumference of the collar”. Therefore, when the ratio is 1: 3 and the foot is moved 10 cm on the shaft with a circumference of 10 cm and the shaft is rotated once, the shaft (massage device) is placed on the floor in the same direction as the sole through the collar. It will move 30 cm above, and the sole will move 10 + 30 = 40 (cm) relative to the floor. When you move your foot back and forth, you can reciprocate with the sole moving 40 cm. If the ratio is set to 1: 3.5 under the same conditions, it moves 10 + 35 = 45 (cm), which is particularly effective when the shoulder joint is to be moved greatly. If the shaft is used at a fixed position, this is a 10 cm movement.

When the ratio is 1: 3, it is 4 times that of the conventional product that uses the massager at a fixed position on the floor, and nearly twice that of the massager that is directly placed on the floor. The sole of the foot can be moved, and a reciprocating motion that greatly moves the knee joint with a small amount of movement (fatigue) can be performed while massaging. Moreover, when the hand is placed on the axis of the massager and moved, a reciprocating motion that greatly moves the joints of the shoulder and elbow can be performed. In addition, a foot motion that is three times faster corresponding to the ratio can be obtained without feeling tired.

A supplementary explanation will be given with reference to FIG. The chart shows the difference between the massage device circumference ratios (1: 3 and 1: 1) when the foot 53 is placed on the shaft 51 with a circumference of 10 cm, moved 10 cm, and the shaft 51 is rotated once. The movement of the contact point between the back and the shaft 51 is compared. Perimeter ratio indicates shaft 51 (including protrusions): flange 52 (including rubber ring). Point A contact point 55 is a contact point between the sole and the shaft before the sole is moved on the shaft. Point B contact point 56 indicates a contact point between the sole and the shaft after the sole is moved on the shaft.

In FIG. 6, protrusions and rubber rings are omitted for easy combination with the table. When the shaft 51 and the flange 52 are concentric circles, the contact between the sole and the shaft 51 is “0” in the vertical movement, and the contact moves linearly, but when it is other than the concentric circle, it moves up and down. The contact moves according to the width of the vertical movement, as indicated by “curve SS” 54, and the amount (length) and quality of the movement change. Note) A circumference ratio of 1: 1 is substantially equivalent to rolling the shaft 51 directly on the floor.

In addition, it has the effect of preventing the massage device from rolling away from the user and making it difficult to roll away by hollowing out a part of the collar, making part of the collar heavy, etc. . In addition, the disadvantages of the conventional products mentioned in the above-mentioned problems are solved at the same time.

This will be described with reference to FIG. This is one example in which the shaft 1 and the collar 2 are separate bodies, and the collar 2 can be exchanged for another shape (changing the movement of the foot) or disassembled and stored. The shaft 1 is provided with a number of protrusions 1a for massaging the sole in the middle of the round pipe, and pin holes 1b are provided on both sides thereof. The flange 2 is an ellipse having a circumference of 3 to 5 times the circumference of the shaft 1 and is provided with a groove 2a on the outer periphery, and a rubber ring 3 is attached to the groove 2a. In addition, a hole 2b for inserting the shaft 1 into the flange 2 and a detent hole 2c for the flange 2 are provided.

Insert the small rubber ring 4 up to the point beyond the projection 1a from the end of the shaft 1. The brim 2 is inserted to a position in contact with the protrusion 1a of the shaft 1. The tip of the short side of the L-shaped pin 5 is directed toward the flange 2, the longer side is passed through the pin hole 1b, the tip is aligned with the detent hole 2c of the flange 2, and the flange 2 is connected to the L-shaped pin 5 Move towards The position of the collar 2 is determined by shifting the rubber ring small 4 between the collar 2 and the protrusion 1a.

When replacing the elliptical flange 2 shown in FIG. 1 with a different shape, the rubber ring small 4 and the flange 2 are returned in the reverse procedure to the above, and then the L-shaped pin 5 is pulled out to separate the flange 2. The L-shaped pin 5 is inserted again, the flange 2 is shifted toward the L-shaped pin 5, and the small rubber ring 4 is shifted between the flange 2 and the projection 1a.

When the foot is placed on the axis 1 and moved back and forth, a reciprocating motion that greatly moves the knee joint and a sole massage can be performed simultaneously. In addition, when the hand is placed on the shaft 1 and moved back and forth, a reciprocating motion that greatly moves the joints of the shoulder and elbow can be performed. Since this method of use is the same in the following embodiments, the description in the following embodiments is omitted. Further, in the drawing, the diameter of the shaft 1 is enlarged by about 20% compared to the flange 2 in order to make the details easy to understand. The same applies to the following figures.
