Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a novel pine surgery device for comfortably and effectively performing pine surgery on the soles of the feet, lower back, back, shoulders, etc.

[Conventional technology]

BACKGROUND ART In recent years, various types of pine surgery devices that employ mechanical or electrical methods have been put into practical use in place of manual pine surgery methods performed by acupressure experts such as in shiatsu therapy.

Among these pine surgery devices, devices for pine surgery on the lower back, back, shoulders, etc. include those in which a suitable part of the body is interposed between a pair of pine surgery members that open and close, like a so-called shoulder massager;
There is a type of medical treatment in which a roller is placed below the bed and the roller is moved while being pressed against a suitable position on the body of the therapist lying on the bed. In addition to this, there are also so-called vibrators that are configured to obtain a pine surge effect by propagating vibrations obtained by converting the rotational motion of a motor etc. into reciprocating motion, or vibrations obtained by electromagnetic methods, to appropriate parts of the body. This is a well-known device.

On the other hand, it can also be used as a means to massage the soles of the feet.
Methods such as placing the foot between a pair of pine surge members that open and close based on the same principle as the shoulder massager mentioned above, and methods such as pressing a hand-held vibrator or the like against the sole of the foot. is used.

[Problem that the invention seeks to solve]

However, according to the type of pine surge device such as the above-mentioned shoulder massager, the pair of pine surge members that open and close move to simply massage the appropriate parts of the body, and only special parts of the body (such as pressure points) are affected. It is impossible to perform acupressure-like action such as when applying acupressure with a pine surge member, and the pressure applied to the body from the pine surge member is not constant depending on the pressed location, so that a uniform pine surge effect cannot be obtained. The problem is that it cannot be done.

On the other hand, even if the above-mentioned roller is moved while being pressed against the body, it is of course impossible to produce acupressure-like effects, and each person's body has different unevenness. Despite the presence of the rollers, the structure is such that the rollers only move on a constant trajectory, so the locus of movement of the rollers does not correspond to the unevenness of the body, and therefore even in this case, a uniform pressing force cannot be obtained. It turns out.

Furthermore, even if the method using the vibrator described above is used, it is of course impossible to achieve an acupressure effect, and it is extremely difficult and troublesome to press the vibrator against the body with uniform pressure.

[Means for solving problems]

In view of the above circumstances, this invention is a novel method that allows acupressure to be applied to appropriate areas of the body, and that can always perform pine surgery with a uniform pressing force on various parts of the body that have unevenness. The technical problem was to provide a pine surge device.

The first means for achieving this technical problem is to fix a bearing block at the tip of the retractable rod of the fluid cylinder, and to rotate a spherical pressing part on the bearing block with the tip exposed. A fluid supply and discharge circuit that moves the retractable rod forward and backward by supplying and discharging a working fluid to and from the fluid cylinder, which is movably held, includes a pressing force control that controls the maximum pressing force that acts on the body from the pressing part. It is in the place where the means are set up.

The second means is to fix a bearing block to the tip of the retractable rod of the fluid cylinder, and to rotatably hold a spherical pressing part on the bearing block with the tip exposed. A fluid pressure regulating valve capable of manually adjusting the maximum pressing force acting on the body from the pressing portion is provided in a fluid supply/discharge circuit that moves the retractable rod forward and backward by supplying and discharging working fluid to the fluid cylinder. and a pressure gauge that displays the pressure value of the working fluid regulated by the fluid pressure regulating valve.

[Effect]

According to the first means, the working fluid is supplied to and discharged from a fluid cylinder such as an air cylinder or a hydraulic cylinder by the operation of the fluid supply and discharge circuit, and along with this, the retractable rod of the fluid cylinder moves forward and backward. A pressing part attached to the tip of the retractable rod intermittently presses the user's body (waist, back, shoulders, neck, soles of the feet, etc.). In this case, the pressing part is made of a spherical body and is rotatably held by a bearing block fixed to the tip of the retractable rod, so that when the pressing part comes into contact with the user's body, the pressing part As the part rotates appropriately, no vibration is generated between the body and the pressing part, and damage to clothing and pain to bare skin caused by this sliding is reduced as much as possible. Furthermore,
By the operation of the pressing force control means provided in the fluid supply/drainage circuit, the maximum pressing force that is applied from the pressing part to any part of the body is controlled, so that the pressure is always uniform against the unevenness of the body. It becomes possible to apply an acupressure effect using pressing force.

According to the second means, when the pressing part at the tip of the retractable rod of the fluid cylinder intermittently presses the user's body, the user manually adjusts the fluid pressure regulating valve as appropriate while visually checking the pressure gauge. It is now possible to operate and change the pressing force applied to the body from the pressing part according to the user's preference, so that the user can obtain a pleasant acupressure effect according to his/her own needs. Become.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

As shown in FIGS. 1a and 1b, the air cylinder 1 as a fluid cylinder has a retractable rod 3 fitted and held in a cylinder member 2 so as to be able to move forward and backward, and a retractable rod 3 formed at the lower end of the retractable rod 3. The retractable rod 3 moves forward and backward (up and down) by selectively supplying and discharging air as a working fluid to and from the upper and lower spaces of the piston 3a. A bearing block 4 is provided at the tip (upper end) of the retractable rod 3.
is removably screwed onto the bearing block 4.
A spherical pressing part 6 is rotatably fitted and held at the upper end of the holder via a ball bearing 5.

On the other hand, as shown in FIG. 2, a fluid supply and discharge circuit 10 for supplying and discharging air to and from the air cylinder 1 includes a compressor 11 as a drive source,
a fluid pressure regulating valve 13 that regulates the pressure of air supplied from the compressor 11 to the main passage 12;
, a pressure gauge 14 that displays the pressure value of the air regulated by the fluid pressure regulating valve 13, and a control circuit 15.
The air solenoid valve 18 selectively switches two air passages 16 and 17 communicating with the upper space and the lower space of the piston 3a in the air cylinder 1 based on an electric signal sent from the air cylinder 1. In this case, the fluid pressure regulating valve 13
The maximum air pressure value, that is, the maximum pressing force applied from the pressing portion 6 at the tip of the retractable rod 3 to any desired part of the body can be arbitrarily adjusted manually. Further, the air solenoid valve 18 performs an operation of alternately switching the two air passages 16 and 17 into an air supply passage and an air discharge passage at a predetermined period (for example, 2 seconds). The rod 3 is configured to move forward and backward at a predetermined period.

Note that the fluid pressure regulating valve 1 used in this example
3 is a device that can arbitrarily adjust the maximum pressing force that acts on any part of the body from the pressing part 6, but other pressing force control means, such as a pressure control valve that sets the maximum pressing force only to a constant pressure value. It is also possible to use a configuration using .

Further, although this embodiment uses the air cylinder 1 as the fluid cylinder, a configuration may be adopted in which, for example, a hydraulic cylinder or the like is used instead.

Next, a method for performing pine surgery on any part of the body using the air cylinder 1 having the above configuration will be described.

FIG. 3 shows a method for performing pine surgery on the sole of the foot.
At the same time, a stretchable cloth 22 is stretched so as to close the opening 21, and the feet 23 are placed on this cloth 22 and tightened with belts 24...24. An air cylinder 1 is disposed directly below the air cylinder 23, and a retractable rod 3 of the air cylinder 1 is moved up and down. As a result, the pressing part 6 attached to the tip of the egress/egress rod 3
It is pressed against the sole of the foot 23 intermittently at a predetermined period (for example, 4 seconds). In this case, the upward movement of the retractable rod 3 is stopped when the pressure value of the air supplied to the air cylinder 1 reaches the maximum pressure value set by the fluid pressure regulating valve 13. In other words, the maximum pressing force acting on the sole of the foot 23 from the pressing portion 6 at the tip of the retractable rod 3 is always kept constant. Therefore, when the air cylinder 1 is appropriately moved by a drive means (not shown) and the entire sole of the foot 23 is intermittently pressed by the pressing section 6 at a predetermined period, the sole of the foot 23 is Despite the presence of irregularities, a constant pressing force is applied from the pressing portion 6 to any location.

FIG. 4 shows a method for performing massage on the lower back, back, shoulders, and neck. For example, as shown in the figure, an opening 31 is provided in the mattress base 30 of the bed, and a cloth is placed to cover the opening 31. 32 and lie down on the mat stand 31, and in this state, place the air cylinder 1 directly below the waist, back, shoulders, and neck, and then move the air cylinder 1's egress/retraction rod 3. move up and down. In this case, in order to massage the shoulders or the neck, by tilting the air cylinder 1 by a predetermined angle as shown in the figure, the pressing part 6 at the tip of the retractable rod 3 can reliably press the relevant area.

Furthermore, FIG. 5 shows a method for performing pine surgery on the palm, in which a case 41 having a space for inserting the hand is fixed on the upper surface of the support base 40, and a predetermined amount is inserted into the upper wall of the case 41. A cushion material 42 that has elasticity and is in contact with the back of the hand is attached, and also in this case, the air cylinder 1 is placed directly below the palm.
By moving the retractable rod 3 up and down, the pressing part 6 at the tip of the retractable rod 3 is intermittently pressed against the palm at a predetermined period. In this case, by moving the hand appropriately while the air cylinder 1 is fixedly supported, acupressure can be applied to a desired part of the palm.

〔Effect of the invention〕

As described above, according to the present invention, the pressing part provided at the tip of the retractable rod of the fluid cylinder presses any part of the body intermittently with a constant pressing force. It is now possible to perform pine massage with almost the same feeling as when performing acupressure, and the acupressure action is always applied with a uniform pressing force even on the unevenness of the body, making it possible to perform pine massage with a feeling similar to that of acupressure. Compared to a machine or a vibrator, a more pleasant pine surge effect can be obtained. Furthermore, the pressing part is spherical and is rotatably held by a bearing block fixed to the tip of the retractable rod, so there is no sliding movement between the user's body and the pressing part. No longer occurs, friction is drastically reduced,
Damage to the user's clothes and pain to the bare skin of the user will be reduced as much as possible. In addition, especially according to the pine surge device according to claim 2, the user can change the pressing force by operating the fluid pressure regulating valve while visually checking the pressure gauge, so the user must know the current pressing force before use. It becomes possible to obtain a pressing force according to the user's preference.
