Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a massaging unit in an apparatus capable of applying massaging and acupressure effects to various parts of the human body.

Many methods are known in which mechanical instruments are substituted for oriental treatments known as massaging, pine surgery, etc.

A typical example is a chair-type massaging machine, but the chair used here has a simple mechanical reciprocating motion, and the body parts that can be treated are very limited, such as the shoulders and back muscles. ing.

Furthermore, since the chair reciprocates with a constant stroke, it separates from the body each time it reciprocates, causing the recipient's body to sway due to the reaction, resulting in shocking contact and unreasonable pressure. There are many problems such as difficulty in feeling pleasure and damage to capillaries.

There are also chair-type and bed-type pie breaks,
This has a resonant effect on the body and is uncomfortable.

Moreover, the effect of massaging the muscles is not so great.

In this case as well, the treatment area is extremely limited, and no systemic therapeutic effect can be expected.

Therefore, in consideration of whole body treatment, handheld models were considered, but these are mostly vibration type (vibrators), which can cause discomfort to the patient depending on the treatment area. Sometimes.

Moreover, in order to increase the massaging effect, the weight of the device must be increased, which is a fatal flaw for a hand-held type.

In short, these known treatment devices do not provide massaging or massage effects, but simply provide a pseudo effect.

This invention is configured as a handy type that can be applied to any part of the body, operates by specifying timing for a plurality of fingers facing each other, and in a hydraulic control system.
The present invention aims to provide a massaging unit that gives a twisting motion similar to pulling a muscle to the affected area and can produce a massage effect similar to that of massaging work by a therapist.

Hereinafter, the present invention will be specifically explained based on an illustrated example.

In the figure, reference numeral 1 denotes a base having chambers 2.2 at both ends, and trunnions 3, 3 are provided in the chambers 2, 2, to which stroke adjusters 4, 4 are pivoted, respectively. has been done.

The stroke adjusters 4, 4 are provided with short arm portions 4a, 4a apart from the pivot portion at their proximal ends, and at this position, pins 5, 5 are used to control the first hydraulic piston cylinder. The arms 6a, 6b of the mechanism 6 are pivotally connected, whereby the piston-cylinder mechanism 6 is connected to both fingers 4, 6b.
It is constructed between 4 spaces.

The piston/cylinder mechanism 6 connects a cylinder 6e having ports 6C and 6d at both ends to the arm 6a, and a piston 6f that reciprocates within the cylinder 6e.
is connected to the arm 6b, and an all-port control block 9 is connected to the ports 6c and 6d via hydraulic lines 7 and 8.

This control block 9 is well known in hydraulic systems and is electromagnetically actuated to selectively connect the ports 6c and 6d to the pump 10 and the hydraulic return tank 11. .

A relief valve 12 is provided in the hydraulic line connecting the block 9 and the pump 10.

Then, by the operation of the piston/cylinder mechanism 6.

The stroke adjusters 4, 4 can pivot using the trunnions 3, 3 as first joints.

Each of these stroke adjusters 4, 4 has a tip branched into a plurality of parts, for example, three parts, and each branch part 4b, 4c,
4d, there is a massaging finger 14 with that as the second joint 13.
a, 14b, 14c are pivotally connected, in this case, the fingers 14a, 14b.

A stopper 15 is provided at 14c to prevent the second joint 13 from moving in the opposite direction, and therefore the movement of the second joint 13 is restricted.

These branch parts 4b. 4 c t 4 d and finger 14
A, 14b, and 14c have brackets 16 and 14c, respectively.
17, and a second hydraulic piston-cylinder mechanism 18 is installed and pivotally mounted between both brackets.

This piston-cylinder mechanism 18 has a piston 18b fitted into a cylinder 18a, a piston rod 18c protruding outside, and a head of the cylinder 18a and a piston 18b.
It has a single-sided structure with a compression coil spring 19 interposed between the head of the cylinder 18a and the bottom of the cylinder 18a.
Port 18d is open.

The pump 10 and the hydraulic return tank 11 are communicated with this port 18d via a switching valve 20.

Then, by the operation of the piston mechanism 18, the second joint 13
branch parts 4b, 4c, 4d and massage fingers 14a, 14b.

14c.

Further, a third piston-cylinder mechanism 21 is incorporated in some of the branch portions 4b, 4c, and 4d, for example, the branch portions 4c and 4c facing each other.

That is, this branching part 4C is divided into a base end side and a distal end side, a cylinder 21a is fixed to the distal end side, and a piston 21b inserted therein is biased toward the head side of the cylinder 21a by a compression coil spring 22. , and the cylinder 21a
A supply path 23 for supplying pressure oil to the head of the pump is provided, and the supply path 23 is communicated with the pump 10 and the hydraulic pressure return tank 11 via a switching valve 24.

Then, the stroke adjuster 4, the massage finger 14a1
4b and 14c are each covered with a sponge body 25 with a hydraulic piston/cylinder inside, and the sponge body 25 is covered with a synthetic resin sheet 26.

Note that in this embodiment, one group of stroke adjusters 1
4b, the massage fingers 14a and L4c of the other group are incorporated into a hydraulic system so as to have a common hydraulic circuit.

In such a configuration, in order to massage a suitable part of the body, such as an arm, the control block 9 is first activated to supply pressure oil from the port 6c and discharge oil from the port 6d. The stroke adjusters 4, 4 move their tips toward each other, and the stroke adjusters 14a
514 b and 14 c are in a state where their arms are sandwiched.

Here, the control block 9 is locked, and in this state, the switching valve 20 is operated to switch the second piston/cylinder mechanism 1.
Add pressure oil to some of 8.

As a result, the massage fingers 14a, 14c and the massage finger 14b on the opposite side are bent inward to apply finger pressure.

At the next moment, the switching valve 20 is switched, the pressure oil is removed from the said several of the second piston-cylinder mechanisms 18, and the above-mentioned fingers are returned by the action of the spring 19, while the remaining piston-cylinder mechanisms Pressure oil is added to 18, and the massage finger 14b and the massage finger 14a on the opposite side.

14c is bent inward and finger pressure is applied.

In this way, by switching the switching valve 20, finger pressure is applied alternately on both sides of the arm, thereby producing a massaging effect.

In this case, the massaging fingers are placed in a pinched state by the massaging fingers 4, 4 in advance, so they do not separate from the arms, so the massager has a totally authentic massaging effect, which is shocking. It doesn't do any good work.

In addition, this acupressure/massage unit is fixedly placed on a separate stand or the like, and the massaging finger 14b is attached.

14b and when the switching valve 24 is continuously switched, the third piston/cylinder mechanism 2
1 works and causes the massage fingers 14b, 14b to protrude longer than the other fingers, so that an acupressure effect can be obtained.

In this case, when applying pressure oil, the fingers 14b, 14b slowly push the affected area, and when the oil is drained, they return rapidly by the spring 22, so that the treatment can be performed with the same feel as in actual acupressure treatment.

Thus, according to the present invention, chambers are formed at both ends of the base, a stroke adjuster is pivotally attached to the chambers, and a plurality of tip fingers are provided at the tips of the stroke adjusters, respectively. At the same time, perform the bending and stretching movements of each massaging finger so that the timing of the forward and backward bending and stretching movements of the opposing massage fingers is different and the timing of the adjacent massage fingers is opposite. The hydraulic control system is provided with a switching means, and the switching means is configured to hydraulically operate the fingers belonging to each timing, so that the massaging motion on the affected area becomes a massaging motion with a twist, and a muscle pulling motion. A unique kneading effect can be obtained.
