Description

[Detailed description of the invention] [Industrial field of application] [Prior art] The prior art related to the present invention is a patent application filed in 1983-
No. 232260 is only a continuous acupressure type pressure therapy device, and this technique is a chair-type therapy device as shown in the front view in Figure 1 of the accompanying drawings, the side view in Figure 2, and the plan view in Figure 3. A drive device using a motor is built into the backrest portion 1 of the device, and a drive shaft 4 is moved up and down simultaneously from the drive device at a planned distance, and repeatedly rotates from side to side within a certain range. The drive shafts 4 are made to protrude slightly from the surface of the backrest, and the surface of the backrest 1 is equally cut out as movement grooves 3 so that the drive shafts 4 can move up and down, and each drive shaft 4 has a shape as shown in the figure. The arm 5 is removably fitted therein, but since the arm 5 is made of square bar steel, the hole into which the drive shaft 4 is fitted is also a square hole. Bolts 6 are screwed together, and small-diameter kneading balls 7 made of steel or hard synthetic resin, about the size of a fingertip, are fixed to both ends of the bolts 6. When in use, the upper body is attached to the seat 2. The treatment is performed while sitting, and the lower body is treated while standing on the seat 2.The details of the treatment are as shown in Figures 1 and 2, as each arm can be attached and detached freely. As shown in the figure, two arms 5 are attached, and the arms 5 repeatedly move left and right within a certain range, and the small diameter massage balls 7 move as shown by the arrows. Only one arm 5 as shown in Figure 4
The massager is mounted horizontally and massaged with pressure by placing the shoulder under the small-diameter massage balls 7 that rotate in the direction of the arrow.

[Problem that the invention seeks to solve]

Although the conventional techniques described above have demonstrated revolutionary therapeutic effects, at the same time new problems have been pointed out as described below.

For example, when massaging the legs as shown in Fig. 5, the small-diameter massaging balls 7
If you have a physique that allows you to pass between the two, you can receive sufficient treatment, but
If the body becomes more obese, it will not be possible to insert the massaging balls 7 between the small-diameter massage balls 7, so the spacing between the arms 5 itself will have to be further widened.

In the case of a pinch massage, the part may be not only the leg but also the arm, and in this case, the part is much thinner than the leg, so the interval between the small diameter kneading balls 7 must be considerably reduced.

Therefore, in the conventional technology, the distance between the small-diameter massage balls 7 is adjusted by rotating the bolt 6, but the adjustment amount is, for example, 30 cm wide for the upper leg of an obese person, and 6 cm to 7 cm wide for the arm of a slim person. As a result, the length must be adjusted by approximately 23 cm to 24 cm only by turning the bolt, which is extremely complicated.

In the conventional technology, the size of the small-diameter massage balls 7 is, in principle, about the size of a fingertip for treatment by a shiatsu therapist. It became necessary to have a means by which the massaging balls 7 could be replaced at any time.

[Means to solve the problem]

Regarding the above-mentioned problems, the first point is that a problem arises when the small-diameter massage balls 7, which have a considerable length, are moved and all of this is adjusted by turning the bolts 6. The arm 5 itself is made to be able to move freely within a certain range as indicated by the dotted line in FIG.
This problem can be solved at once by using adjustment as a means for small cases.

Regarding item 2, the small diameter kneading balls 7 fixed to both ends of the bolt 6 are not of the same fingertip-sized shape, but one of the left and right is made into a large diameter kneading ball, or a large diameter kneading ball 8 with a certain degree of flexibility is used. If necessary, it would be extremely rational to freely rotate it 180 degrees in the direction of the arrow in Fig. 7 and place it in place.

[Function and Examples]

The plan view shown in FIG. 8 and the side view shown in FIG. 9 are for easily handling the movement of the arm 5.
9 is directly connected to the drive device in the backrest portion 1, and
The shaft rod is made of a square steel bar that protrudes from the surface of the backrest portion 1 by the required amount, and the shaft rod 9 has a narrow arm receiver 10 of a planned amount with a width into which the shaft rod 9 is inserted, as shown in the figure. , their left ends are brought into close contact and fixed and integrated, and the partition plate 11' is fixed by bringing them into close contact with the shaft rod 9 in the arm receiver 10, and then the partition plate 11' is fixed in a state in which the arm can be inserted. The inner arm frame 11 is then created, and then the outer arm frame 12 is created by fixing the partition plate 11' to the right end of the arm receiver 10 with a width for arm insertion.

As described above, the arm can be freely attached and detached and its position can be moved widely by using the arm frames 11 and 12 of the arm receiver 10 that are integrated with the shaft 9 that is directly connected to the drive device. .

In the above explanation, the arm frames in the arm receiver 10 are shown as two, the inner arm frame 11 and the outer arm frame 12, but these can be replaced by the partition plate 11' as necessary.
There is no problem in increasing the amount to 2 or more by using .

Next, the arm body A is explained with reference to a plan view in FIG. 10 and a side view thereof in FIG. A round steel arm 14 made of round steel whose upper side is bent at 90 degrees is passed through the square shaft 13 and fixed integrally, and at the bent end of the round steel arm 14, A bolt operation tube 15 is fixed at each end, into which a bolt 6 is inserted, which fixes the small-diameter massage balls 7 and the large-diameter massage balls 8, respectively.The bolt operation tube 15 has a special structure. The details are detailed below.

First, as shown in FIG. 12, the bent end of the round steel arm 14 is threaded with a male screw 14'.
The figure shows a regulating tube 16 with a majority of its height passed through the round steel arm 14, and the remainder having a female thread 18 screwed into the male thread 14' of the round steel arm 14. A regulating groove 17 having a shape as shown in the figure is cut in 16.

FIG. 14 shows a coiled spring 19 that can be fitted into the round steel arm 14 and can exert a repulsive force that can achieve the purpose described later.
FIG. 15 shows a bolt operation tube 15, in which a bolt screw 22 is screwed through the tip of a square steel having a planned height, and the above-mentioned regulating tube 16 can be inserted from the top thereof. An operating hole 23 is drilled in the rear end of the operating hole 23, and screw holes 21 are bored at equal positions on both sides of the rear end of the operating hole 23 and in the center thereof.

Each member from the round steel arm 14 in FIG. 12 to the bolt operation tube 15 in FIG. 15 is as shown in FIG. 16.
First, the ring 20 and the spring 19 are inserted into the round steel arm 14, and then the regulating tube 16 is inserted, and the male thread 14' and the female thread 18 are screwed together to form the round steel arm 1.
4 and the regulating tube 16 are integrally connected, and then the bolt operation tube 15 is inserted into the regulating tube 16 as shown in FIG.
is compressed, the ring 20 is positioned at the bottom of the screw hole 21, the screw 24 is inserted and fixed, and the screw 24 is also inserted and fixed into the screw hole 21 that matches the regulation groove 17, and the bolt screw 22 is inserted here. Bolts 6 are screwed together and small-diameter massage balls 7 and large-diameter massage balls 8 are attached to both ends.
This completes all connections by fixing the .

In this way, the bolt operation tube 15 screwed to the bolt 6, which has the small diameter massage balls 7 and the large diameter massage balls 8 connected to each end, can be opened by grasping the bolt 6 and pulling it, and then holding the screws 24 on both sides to make a ring. 20 and compressing the spring 19, the screw 24 in the center moves over the vertical groove of the regulating groove 17 and reaches the horizontal groove, where it is rotated 180 degrees with the bolt 6 and screws 24 again.
When the bolt 6 is released after aligning the vertical grooves with the bolt 6, the screw 24 is fixed in the vertical groove by the repulsion of the spring 19, and by the above operation, the small-diameter massage balls 7 fixed to both ends of the bolt 6 and the large The diameter of the massaging balls 8 can now be changed freely by 180 degrees.

〔Effect of the invention〕

According to the present invention as explained above, when the distance between the massage balls 7 and 8 varies greatly depending on the physique of the practitioner or the displacement of the treatment area, the inner and outer arm frames 11,
12 and the movement of bolt 6 may be used only for short transitions, so bolt 6
The length can be shortened to the necessary minimum, and the inefficiency caused by operating only the bolt 6 between long lengths can be greatly improved. Large diameter kneading balls 8
Comrades, small-diameter massage balls 7, comrades, large-diameter massage balls 8 and small-diameter massage balls 7, can be freely and easily converted, and are a breakthrough that embody the means that the conventional technology has never stopped aspiring for.
