The present invention relates to nozzle control of a hydraulic massage device.

An example of a conventional hydraulic massage device is shown in FIG. FIG. 7 (A) is a side sectional view of the apparatus when the user M is performing massage and FIG. 7 (B) is a plan view of the inside of the tank.
The apparatus is movable in the longitudinal direction of the tank 1 (the height direction of the user), the tank 1, the liquid 2 filled in the tank 1, the flexible membrane 3 stretched in a watertight manner in the upper opening of the tank 1 A carriage 18, a carriage drive shaft 6 that moves the carriage 18, a carriage drive motor 7 that drives the carriage drive shaft 6, and left and right (short sides of the tank 1) that are rotatably mounted on the carriage 18 around the rotation axis O Direction) a pair of turntables 19, a nozzle 4 provided eccentric to the turntable 19, a turntable drive shaft 20 that drives the turntable 19, a turntable drive motor 21 that drives the turntable drive shaft 20, It has a frame 8 that supports the tank 1 and an exterior 9 of the entire apparatus.
Although not shown in the figure, the apparatus includes a control unit that controls the entire apparatus including the control of the position of the nozzle 4 as described above, an input unit that sets treatment conditions, and a state of treatment. Has an indicator to display

The carriage 18 and the carriage drive shaft 6 are connected by screws or gears. When the carriage drive motor 6 rotates or reversely rotates the carriage drive shaft 6, the carriage 18 can be moved in the longitudinal direction of the tank 1.

The turntable 19 is provided on the carriage 18 so as to be rotatable about the rotation axis O. A pair of right and left (short direction of the tank 1) is provided, and the two turntables 19 are gear-coupled.
One end of the pair of turntables 19 is connected to the turntable drive shaft 20 by a screw or a gear.
For this reason, when the turntable drive shaft 19 is rotated or reversely rotated by the turntable drive motor 21, one turntable is rotated and the other turntable is rotated in the reverse direction.

The nozzle 4 is provided eccentrically from the rotation axis O of the turntable 19, and when the turntable 19 is rotated, the nozzle 4 performs a circular motion.

The tank 1 and the pump 5 and the pump 5 and the nozzle 4 are connected by a flexible pipe. When the apparatus is operated, the pump 2 pumps the liquid 2 inside the tank 1 to the nozzle 21, and the nozzle The liquid is sprayed from 4 toward the membrane 3, and the user M riding on the membrane 3 is massaged with this hydraulic pressure.

A reference point 22 serving as a reference for placing and positioning the user is provided on the exterior 9 of the apparatus, and when used, the reference part of the user is placed on the film 3 with the reference point 22 aligned. Usually, the reference point 22 often takes a shoulder.

When the user puts the reference part on the membrane 3 with the reference point 22 aligned and inputs height information, the length L from the neck to the height (hereinafter referred to as the shoulder section) to the foot is calculated from statistical data on the body type. can get.
When massage is started, the nozzle is controlled within this range, the nozzle moves in the height direction while rotating, and massages from the shoulder to the foot (hereinafter referred to as the whole body).
(For example, Patent Document 1).

However, since the leg is lighter than the trunk, the leg of the user is lifted and the massage pressure is reduced during leg massage.
In addition, since the nozzle rotates in a state where the legs are lifted, both the legs are gradually pushed left and right and may move outside the massage range.
For this reason, there existed a problem that the massage effect fell or it was not obtained.

The problem that the legs are lifted and the massage pressure is reduced is dealt with by placing a weight on the legs so that the legs are not lifted by water pressure.
However, the weight gives a feeling of pressure and the user may feel uncomfortable. In addition, it takes time and effort for the caregiver to place and remove the weight. In addition, the extra work of weight management is also necessary.
Also, when a weight is placed, it seems that the legs can be prevented from opening left and right at first glance, but in reality, the legs cannot be sufficiently prevented from opening.

When the distance L from the shoulder section to the foot obtained by inputting the height matches the distance Lr from the actual shoulder section to the foot of the user, it is possible to accurately massage from the shoulder to the foot. .
However, if the user's body shape deviates from the average value of the statistics, the distance L from the shoulder term part to the foot obtained by inputting the height is the distance Lr from the user's actual shoulder term part to the foot. It does not match.
If the distance L is smaller than the distance Lr, it is possible to massage only halfway through the leg, and if the distance L is greater than the distance Lr, the nozzle moves to a site where the user's leg does not exist, causing a useless jet. As described above, when the distance L is different from the distance Lr, a sufficient massage effect cannot be obtained or waste occurs.

In addition, if the reference part is shifted from the reference position, unnecessary parts (parts that do not want to be massaged, such as the head) are massaged, or only part of the leg is massaged, or jets flow to parts where there is no leg May be issued. For this reason, a bad influence is given to a user, sufficient massage effect cannot be acquired, or useless operation arises.

The nozzle 4 is provided eccentrically from the rotation axis O of the turntable 19, and when the turntable 19 is rotated, the nozzle 4 performs a circular motion.

  When the device is activated, the nozzle 4 moves in the longitudinal direction of the tank while rotating in opposite directions, and massages the entire body of the user with a jet from the nozzle.

Although the above structure is the same as that of the conventional hydraulic massage apparatus, in this embodiment, a sole contact portion K is further provided.
As described above, in the hydraulic massage device, the user places the reference part on the membrane 3 with the reference point 22 aligned, and when height information is input, the user's shoulder is calculated based on the statistical data on the body shape and the user's height. The distance L from the term part to the sole is obtained, and in the range from the reference point to the distance L, the nozzle 4 moves in the longitudinal direction of the tank while rotating and massages the whole body of the user.
However, as described above, when the user is placed at a position shifted by δL from the reference point 22, the movement range of the nozzle 4 and the range from the shoulder portion of the user to the sole are shifted by δL. For this reason, massage the part you do not want to massage, massage only to the middle of the leg, jet out to the part where the leg does not exist, adversely affect the user, and obtain a sufficient massage effect It may not be possible or useless operation may occur.
According to the present embodiment, the sole contact portion K is provided in the tank 1, and the position of the sole contact portion K is set as a reference point.

An example of massaging the whole body by rotating by combining the table drive shaft 20 and the turntable drive motor 21 was shown, but what if the nozzle 4 can be controlled in the longitudinal direction and the short direction inside the tank 1 It may be a simple structure.

Further, 10 in FIG. 2 is a sole contact portion, and F is a user's foot.
When the user abuts the foot F against the recess of the sole abutting portion 10, the foot does not move left and right, and thus the leg does not open to the left or right even if a hydraulic massage is performed.
Conventionally, both legs are gradually spread to the left and right by the jet, and move outside the massage range, resulting in a problem that the massage effect cannot be obtained.
This embodiment can solve this problem.

In the embodiment of FIG. 2, the structure prevents the legs from opening left and right, but if the structure does not move up and down, both legs are lifted by the jet flow, the pressure is reduced, and the massage effect is reduced. Can also be prevented.
It is desirable to prevent the legs from moving left and right and up and down.
In FIG. 3A, 11 is an air bag, and 12 is an air pump. When the air bag 11 is filled with air and the foot is compressed, the foot can be fixed to the sole contact portion, and the leg can be prevented from moving both vertically and horizontally.

For the pressurization, any massage method such as air pressure, roller, hydraulic pressure, mechanical force, vibration, etc. may be used, or these may be used in combination.
Further, the leg massage means may massage part or all of the legs, as well as massage only the legs as shown in FIG.

(Example 3)
A third embodiment of the present invention is a hydraulic massage device characterized in that the sole contact portion is used as a reference point for the position on the user's device.
When the user puts the sole portion on the sole contact portion and puts it on the apparatus, all the users can be positioned at the reference position.
In the conventional apparatus, the reference point is set as the end of the nozzle movement range, but in this embodiment, the reference point is set as the end of the nozzle movement range so that the nozzle does not move farther than the reference point. I have to. For this reason, since the nozzle does not move farther than the user's foot, waste can be eliminated.
As mentioned above, when the user puts it off the reference position and performs a hydraulic massage, it massages unnecessary parts (parts that do not want to be massaged, such as the head) or massages only halfway through the legs. Or jets may be emitted to areas where there are no legs. For this reason, a bad influence is given to a user, sufficient massage effect cannot be acquired, or useless operation arises.
According to the present embodiment, since all users can be adjusted to the reference point by simply contacting the sole with the sole contact part, it is possible to solve the problem that occurs when massaging out of the reference position. .

  This embodiment is shown in FIG. The figure is a plan view when the user is placed on the device in a supine position. In FIG. 4, 15 is a reflective position sensor provided on the user's head side, 16 is a reflective or transmissive position sensor arranged in the longitudinal direction of the tank, and K is a sole contact portion.

In FIG. 4 (A), the user is in a supine position on the apparatus by contacting the sole with the sole contact part K, and the position of the top of the head is detected by the reflective position sensor 15 from the sole. The distance to the top of the head, that is, the height of the user is obtained. From this height data and statistical data on the physique, a distance L from the shoulder to the sole is obtained, and during this time, the position of the nozzle is controlled to perform a hydraulic massage.

FIG. 4B differs from FIG. 4A only in the position sensor of the top position detecting means. The user comes into a supine position on the apparatus by contacting the sole with the sole contact portion K, detects the position of the top of the head with the transmission type position sensor 16, and the distance from the bottom to the top of the head, that is, The height of the user is obtained. From this height data and statistical data on the physique, a distance L from the shoulder to the sole is obtained, and during this time, the position of the nozzle is controlled to perform a hydraulic massage.
The position sensor 16 may use a reflective position sensor to measure the distance to the shoulder or neck and recognize the shoulder term from the difference in distance.

Since the distance L from the shoulder to the bottom of the shoulder obtained in this way matches the length Lr from the shoulder to the bottom of the actual user, unnecessary parts are not massaged and not massaged. There is no part, and the nozzle is not moved to an unnecessary position where there is no body. In other words, a safe, effective and efficient massage can be performed. Further, labor for setting a massage range such as height input can be saved.

Example 4
According to a fourth embodiment of the present invention, the shoulder part detecting means for detecting the position of the user's shoulder or neck provided in the tank, and the position of the shoulder or neck detected by the shoulder part detecting means. And a nozzle control means for operating the nozzle within a range up to the reference point.
This embodiment is shown in FIG. The figure is a plan view when the user rests on the device in the supine position, 15 is a reflective position sensor for detecting the position of the shoulder provided on the user's head side, and K is the sole contact portion. .

In this embodiment, the position of the shoulder is obtained by the reflective position sensor 15 provided on the head side, the distance from the sole to the shoulder position is obtained, and the nozzle is controlled within this range to perform the whole body massage.

In the above example, the shoulder position is measured by the reflective position sensor 15 provided on the head side. However, any sensor may be used as long as the shoulder position can be obtained. For example, the transmission type position sensor 16 shown in FIG. 4B can be used.

The shoulder position is the position of the tip of the shoulder. In the conventional liquid massage apparatus, as described above, the shoulder position is adjusted to the reference point 22 and the whole body from the reference point to the foot is massaged. Actually, the nozzle is controlled from the head side slightly from the reference point so that the neck muscle can be massaged slightly above the shoulder.
In this embodiment, the nozzle moving end of the foot is the sole contact portion, and the nozzle moving end on the neck side is a position obtained from the height data. This point has some errors due to physique differences. The term shoulder term is used in the sense of having this slight error. It does not indicate a wide range from the shoulder to the upper part that is generally used. Actually, it is corrected and used so as to massage around the middle of the neck and the lower part of the neck.
As described above, the massage range of the shoulder part has some errors depending on the user.
However, since the present embodiment directly measures the shoulder position to determine the massage range, there is no individual difference in the massage range, and a more accurate range can be massaged.

(Example 5)
In the fifth embodiment of the present invention, a massage position is determined from longitudinal position detection means for detecting the longitudinal position of the tank and information on the longitudinal position of the tank detected by the longitudinal position detection means. A fluid pressure massage apparatus comprising: a massage range setting means for controlling the nozzle within a range set by the massage range setting means.

This embodiment is shown in FIG. 17 in the figure is a key switch of position detecting means arranged in the longitudinal direction of the tank 1.
When a switch a in the key switch 17 is pressed, the nozzle can be controlled in a range from the sole to the position A corresponding to the switch a to massage between them.
When the switches a and b in the key switch 17 are pressed, the nozzle is controlled within the range from the position A corresponding to the switch a to the position B corresponding to the switch b, and the range from the position A to B is massaged. can do.
In the above example, an example in which key switches are arranged has been shown, but any means can be used as long as it can specify a desired massage range.
According to the present embodiment, a desired position can be specified and the range can be massaged, so that effective and efficient massage can be performed.
