Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a foot blood circulation promoter.

[Conventional technology]

Devices that stimulate the soles of the feet to relieve fatigue and improve health have been popular on the market, but these include semicircle-shaped devices, plate-shaped devices with many protrusions, and rotatable rollers. It is roughly divided into types. The inventor of this idea was already in the 1970s.
No. 87446 and No. 56-173839 disclose plantar blood circulation promoters using rollers with spiral protrusions formed on the outer circumferential surface, but in both of these, a single roller is mounted on a base plate, and In the latter case, with the brake plate with an integrated anti-rolling piece attached, place your foot on the spiral protrusion on the roller, press it lightly, and move the entire sole of your foot back and forth to rotate the roller. It is something. but,
The effect of using such a single roller is still not satisfactory.

[The problem that the idea aims to solve]

As described above, the conventional foot blood circulation promoters have many problems, such as not being very satisfactory in their effectiveness and being bulky and inconvenient to carry. This had become an issue.

[Means to solve the problem]

In order to solve the above problems, this invention has protrusions on the outer circumferential surface and rotating wheels on both ends.
Outside the center of both rotating wheels, a short shaft is provided with a tapered portion at the tip similar to a countersunk screw or a round flat screw, and two flat washers are attached to the short shaft via a spring. penetrates at least 2
A sole composed of a book roller and a pair of clamping plates having two or more notches at an arbitrary interval on at least the outer surface thereof into which the tapered part of the short shaft tip fits. It adopts a means of promoting blood circulation.

[Effect]

At both ends of the roller, a short shaft is provided, which has a tapered part similar to a countersunk screw or a round flat screw, and passes through two flat washers via a spring. When the clamping plate is placed between the washer and the short shaft is inserted into the notch, and the taper part and the recess are aligned, the two will fit together strongly and securely due to the repulsive force of the spring, and the short shaft will fit firmly and securely. Although it is rotatable, it does not easily separate from the clamping plate. Further, the roller can be easily removed from the clamping plate by pushing the clamping plate in the direction of the roller against the repulsive force of the spring so that the tapered portion of the short shaft rises from the recess and moves it along the notch.

〔Example〕

This invention will be explained below based on drawings showing examples.

A spiral protrusion 2 is formed on the outer peripheral surface of the roller 1,
Rotating wheels 3 are integrally formed at both ends. And in the center of the side of each rotating wheel 3 is a spring (helical spring).
A short shaft 6 was formed by vertically inserting a cross-recessed open wood screw passing through two flat washers 5 and 5' with 4 interposed therebetween. On the other hand, a pair of clamps are provided with three notches 8, 8' and 8'' formed at arbitrary intervals on the surface where the recess 7, in which the tapered end of the short shaft 6 fits snugly, is located on the outside. A clamping plate 9 was prepared, and the tips of the short shafts 6 of each of the two rollers 1 were inserted into it so that they were parallel to each other, as shown in the figure.The rollers 1 inserted into the clamping plate 9 Although the tapered portion of the short shaft 6 rotates freely in the recess 7 formed in the notches 8 and 8', the holding plate 9 is pushed against the repulsive force of the spring 4, and the tapered portion of the short shaft 6 is rotated freely. It will not come off unless it is lifted out of the recess 7. Also, if you want to change the distance between the two rollers 1, you can use the third notch 8'' as appropriate. By placing the soles of your feet on the two parallel rollers 1 and moving them back and forth, you will not only feel more stable than when using only one roller, but you will also be able to simultaneously move the arches of your feet and the bases of your toes. I was able to perform a pine surge and experience a wonderful sensation of pleasure. Furthermore, not only the interval between the rollers can be adjusted, but also disassembly and assembly are easy, making it convenient to carry.

Furthermore, since the recess 7 of the plate 9 is pressed against the tapered portion of the short shaft 6 by the force of the spring 4, the roller 1
Appropriate braking is applied to the rotation of. Therefore, even when the foot is removed from the roller 1, the roller 1 does not roll unnecessarily.

〔effect〕

As mentioned above, in the sole blood circulation enhancer of this invention, multiple rollers and multiple clamping plates can be assembled and disassembled at any time with simple operations, making it convenient to carry. It is also possible to adjust the pine surge effect as desired by increasing or decreasing the number or adjusting the spacing depending on the size of the feet, and the disassembled rollers can be used for both feet or used by others. Since this can be done easily, it can be said that the significance of this invention is extremely large.

In addition, the clamping plate of this invention not only connects multiple rollers, but also rotates the rollers by pressing the tapered part of the short shaft fitted into the recess of the plate with spring force. Since the brake is applied with an appropriate amount of force, there is also the convenience that the roller will not roll unnecessarily when the foot is removed from the roller.

Further, the above-mentioned force prevents the plate from falling off from the tip of the short shaft, making disassembly and assembly easy, and preventing the plate from coming off unnecessarily during use.

Furthermore, by attaching one plate to one side of one roller and the other plate to one side of another roller, each roller can be separated and one foot placed on each roller. It is also possible to perform pine surgery.
