Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pine surgery machine in which a treatment element moves along the back curve of the body.

The conventional pine massage machines that perform what is called "rolling pine surgery" or "mass massage" using a massager that moves along the back column while resting the body on a treatment table like a chair or bed, are If the locus is fixed in advance and the locus of movement is linear, the massager will hit too hard on the buttocks and central back, and conversely, the massager will hit the upper waist, shoulders, and neck too hard. It has the disadvantage that treatment cannot be performed due to insufficient contact pressure, and in order to overcome this disadvantage, a device in which the movement locus of the treatment element forms an S-shaped curve has been provided. A person whose body shape fits a fixed S-shaped curve (for example, a standard adult male)
However, there are large variations in human body shape (for example, a large adult male and a petite adult female have a difference of about 20 crrt).
There is a difference in sitting height.

) It was not something that would satisfy the majority of people.

In particular, rolling pine surgery, which has the purpose of softening the back column and restoring and improving the motor and nervous functions of the body, in which a roller-shaped treatment element rolls along the back column, is especially effective for body shape. It is required to draw the exact movement trajectory.

However, with conventional methods, for example, people with a hunched back or body shape that deviates from the standard body type cannot receive sufficient treatment, and unnecessary pressure may be applied, resulting in adverse effects.

The present invention was invented in view of the above-mentioned points, and its purpose is to detect and memorize the back curve unique to the treated person, and to transfer the treatment element along the memorized curve to help the treated person. The treatment child draws a movement trajectory that suits each person without choosing the body shape of the body, so the treatment child may not come into contact with the light and cannot obtain the pine surge effect, or the treatment child may be hit too hard and feel pain, or vice versa. To provide a pine surgery machine that performs comfortable and effective pine surgery regardless of the body shape of the person to be treated without causing any effects.

The present invention will be described in detail below based on illustrated embodiments.

An upholstery 2 is provided on the upper surface of the bed-shaped treatment table 1, and an elastic band 3 is provided on the lower surface of the upholstered cloth 2 to bear the load on the tips of the legs, the buttocks, and the head at the center of the back. .

A pine surge mechanism is installed inside the treatment table 1, and on both sides of the treatment table 1 there are installed rails 4, 4, which have a U-shaped cross section and are open upwards, spanning almost the entire length of the treatment table 1. A rack 5 is provided along the rail 4.4.

6 is a carrier on which the pine surge mechanism is mounted; one end is provided with a drive shaft 7, the other end is provided with a rotating shaft 8, and rollers 9 are freely rotatably attached to both ends of the driving shaft 7 and to both ends of the rotating shaft 8. It is possible to move freely on the rail 4.

The drive shaft 7 is rotatably attached to the carrier 6, and in addition to the rollers 9, a pinion 10 that meshes with the rack 5 is fixed to both ends, and a worm wheel 11 is fixed to the center. There is.

This worm wheel 11 meshes with a worm shaft 13 provided on the output shaft of a motor 12 that can freely rotate forward and reverse, so that when the drive shaft 7 rotates due to the rotation of the motor 12, the carrier 6 runs along the rail 4. It is.

Reference numeral 15 denotes a gear fixed to the drive shaft 7, which is attached to the carrier 6 and is finally connected to a position detection gear 18 via reduction gears 16 and 17.

As shown in FIG. 5, a conductive leaf spring 19 is attached to one side of this gear 18, and the leaf spring 19 comes into contact with a position detector 20 disposed opposite to the side of this gear 18. do.

The position detector 20 is equipped with a printed circuit, and has a ring-shaped common terminal in the center and n terminals radially arranged as shown in FIG. Establish continuity between the common terminal and any terminal depending on the position.

At this time, since the moving stroke of the carrier 6 is set to be one rotation of the gear 18, the position of the carrier 6 in the middle of the treatment table 1, that is, the rotation angle of the gear 18 is converted into a signal of 1 to n.

Reference numeral 21 denotes an upper and lower plate whose one end is rotatably supported by the drive shaft 7, and a shaft 23 on which a plurality of roller-shaped treatment elements 22 made of an elastic body is supported is disposed on the upper surface of the other end. Lever shaft 2
Both ends of 3 are supported by bearings 24, 24.

The other end of the upper and lower plates 21 is rotatably connected to the upper end of the vertical shaft 25 by a pin 26, and as the vertical shaft 25 moves up and down, the upper and lower plates 21 rotate around the drive shaft 7, allowing treatment. The child 22 is moved up and down.

The vertical shaft 25 is male threaded except for the upper and lower ends.
The male thread engages with a female thread on the inner peripheral surface of a worm wheel 23 attached to the carrier 6 by a bearing 27.

The worm wheel 23 meshes with a worm shaft 30 provided on the output shaft of a motor 29 that can freely rotate in forward and reverse directions.

Further, the lower end of the vertical shaft 25 has a non-circular cross section, for example, a hexagonal shape, and also has a hexagonal hole to support the carrier 6.
It is fitted with a bearing 31 fixed to the shaft, and is slidable in the vertical and axial directions, but is not rotatable.

Therefore, the rotation of the motor 29 causes the vertical shaft 25 to move up and down via the worm shaft 30 and the worm wheel 28.

A detection rod 33 is further provided in the center of the carrier 6.

This detection rod 33 has a non-circular cross section, is non-rotatably but vertically movable supported by a pair of bearings 34, 34 on the carrier 6, and is further urged upward by a push-up spring 36 that comes into elastic contact with a ring 35 attached at the bottom. ing.

A contact 37 is fixed to the upper end of the detection rod 33, which is curved to have approximately the same curvature as the outer peripheral surface of the treatment element 22 and positioned directly above the center of the shaft 23.

Furthermore, ranks 38 are provided on the upper and lower sides of the center of the detection rod 33 and mesh with a gear 39, and this gear 39 is further connected to a gear 42 for vertical position detection via reduction gears 40 and 41. There is.

This gear 42 is configured similarly to the gear 18 described above, faces the position detector 43, and detects the vertical position of the contactor 37 from 1 to n.
It is designed to be output as a signal.

Next, the operation will be explained.

When the human body is placed on the treatment table 1, the body is supported in a straight and natural posture by each band 3 and the upholstery 2.

Treatment begins in this state, but both motors 12,
As shown in FIG. 7, the drive of the drive unit 29 is carried out by the program and control of a control element CPU, which is composed of a central processing unit such as a microcomputer and associated elements.

At the initial stage, when started, the motor 29 is first driven to lower the treatment element 22 via the vertical shaft 25.

In this state, the treatment element 22 does not come into contact with the back surface of the human body, and only the contact element 37 comes into contact with the body.

Next, the motor 12 is driven to rotate the drive shaft 7, and the carrier 6 is moved by the engagement between the pinion 10 and the rack 5.

At this time, the position of the carrier 6 is detected by the position detector 20, and after being A/D converted, it is input to the storage element.

As shown in FIG. 8, if the height direction of the body is taken as the y-axis, and the vertical direction is taken as the y-axis, then this position detector 20
(i=1 to n) are output sequentially.

At the same time, the contact 3T, which was urged upward, descends due to contact with the body, and the vertical position of the detection rod 33 at this time is detected by the position detector 43, and yi (i = 1 to n) is detected by the position detector 43. Output.

This is also A-D converted and input to the storage element.

By moving the carrier 6 in this way, each yi at the xi point on the body is plotted, and the back curve of the body on the treatment table 1 is monitored as yi=F(xi).

Once the back curve is memorized, the control element CPU moves to the next program, rotates the motor 12 to move the carrier 6 at a constant speed, and controls the forward and reverse rotation of the motor 29 to move the treatment element 22 to the back of the body. The material is brought into contact with the material under a predetermined pressure.

That is, the difference between yi at the already memorized point xi and the current y/s obtained from the contact element 37 that is in contact with the body together with the treatment element 22 is 1yl + ΔA - y'il
The motor 29 is controlled so that the distance is within a certain amount ΔE.

In other words, if yi+ΔA-y' i > 0, the vertical axis 2
5, and if yi + ΔA- y' i < O, raise the vertical axis 25 and decrease or decrease the value of y/t, lyi + ΔA-
Y'il-! The motor 29 is rotated until ΔE is reached.

In other words, ΔA is the pressing force of the treatment element 22 against the body, and ΔE is a very small amount that is an allowable error.

This control 70-chart is shown in FIG.

The treatment child 22 is Δ than yi at the previously memorized xi point.
Since the contactor 22 moves upward by A±ΔE, the contactor 22 always contacts the body with a predetermined pressure at each point xi.

If the value of ΔA can be changed at any time, the strength can be selected.

Note that xi is constantly changing as carrier 6 moves.
Y (yi + ΔA ± ΔE) corresponding to Xi has a time delay, but the rate of change of xi, that is, carrier 6
Since the moving speed of is very slow, there is no practical problem.

In addition, in the above embodiment, the treatment table 1 is a bed type, but
A chair type built into the backrest may also be used.
2 shows a roller-type device that simply performs rolling pine surge, but of course it can also be a device that performs a kneading motion, such as a pair of rotating and driven kneading wheels tilted toward each other. good.
