Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a handy massaging unit that can apply the required massaging action to any part of the body.

Conventionally, most known massaging units have been of the vibrator type, and there has been no one that pinches and massages muscles.

There is also a chair-type device in which the joint swings and presses on the shoulder muscles, but this can only be applied to one part of the body and cannot be used for the whole body, and it cannot be used in practice. It is a mechanical action that bears little resemblance to the massaging performed by massage therapists, and is only meant to be soothing.

This invention was made based on the above circumstances, and has the same function as the massaging effect of human hands and fingers, can be used throughout the body, and has various changes in the massaging effect on muscles. The object is to provide a massaging unit that can exert a massaging action in the most suitable state for a local body area.

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

In the figure, reference numeral 1 denotes a plate-shaped base, and sections 2, 2 are provided at both ends of the base 1.

A first finger 3 is pivotally connected to one faculty, and a second finger 5 is pivotally connected to this via a joint 4.

A piston-cylinder mechanism 6 is installed between the fingers 3 and 5.

This piston cylinder mechanism 6 has a piston rod 8 inserted into a cylinder 7, and a piston 9 at the inner end of the piston rod 8.
It has a structure in which the piston 9 is elastically supported by a compression coil spring 10, and when pressure oil is introduced from the port 7a of the cylinder 7, the piston 9 is moved against the spring 10.

In addition, the other faculty has three first fingers 11° 11a.
, 11b are pivotally connected, each having a joint 1
Three second fingers 13.13 via 2, 12a, 12b
a and 13b are pivotally connected.

Above indicators 11 and 13.11a and 13a, 11b and 13b
The same piston-cylinder mechanism 6 as described above is installed between the two.

One end of another piston/cylinder mechanism 14 is pivotally attached to the first finger 11a, and the other end of the piston/cylinder mechanism 14 is pivotally attached to the first finger 3.

The piston/cylinder mechanism 14 has two pistons 1
5 and 15 into the cylinder 16, and the piston rod 1
7 and 17 protrude from both ends, with a port 18 at the center of the cylinder 16 and ports 19°1 at the left and right ends.
It is equipped with 9.

The cylinder 16 is fixed to the base 1.

Further, the first finger 11a is further equipped with another piston-cylinder mechanism 20.

This piston/cylinder mechanism 20 has two parts in the cylinder 21.
Insert and insert the pistons 22 and 22 into the piston rod 23.
, 23 protrude from both ends, and the compression coil spring 2
The pistons 22 and 22 are held inward by the pistons 3 and 24, and a port 25 is opened in the center to supply pressurized oil.
The pistons 22, 22 are configured to press outward against the springs 24, 24.

A first finger 11 is attached to the piston rod 23°23.
and the lower ends of 11b are pivotally connected.

These fingers 11 and 11b are pivotally connected by pins 26.26 to a pivot 27 which is integral with the first finger 11a.

The port 7a of the piston/cylinder mechanism 6 is connected to the piston/cylinder mechanism 14 via the switching valve 28.
The ports 18 and 19 of the
Further, the port 25 of the piston/cylinder mechanism 20 is alternately communicated via a switching valve 30 with a supply path 32 connected to the delivery of the pump 31 and a drain path 34 that returns pressure oil to the tank 33. The switching valve 28 is switched at regular intervals.

Further, the other switching valves 29 and 30 are manually switched.

In addition, in the figure, the reference numeral 35 is a sponge attached to the tip of the second finger, and the reference numeral 36 is a soft synthetic resin outer cover that covers the entire frame.

In such a structure, in order to massage a suitable part of the body, for example, an arm, the switching valve 29 is first activated.
Pressure oil is supplied from port 18, and oil is discharged from port 18. First fingers 3 and 11° 11a, 11bc! : move their tips toward each other, and the second fingers 5 and 13.13a, 13b are in a state where they are sandwiching their arms.

- At this point, the switching valve 29 becomes locked, and in this state, the switching valve 2B operates, so that the second finger 5 and 13.1
3a.

13b for massaging and loosening.

In this case, in order to enhance the acupressure effect, the distance between the second fingers 13 and 13b relative to the second finger 13a may be narrowed.

To do this, if the switching valve 30 is activated and pressure oil is supplied to the port 25, the first fingers 11, 11b rotate around the pin 26, and the second fingers 13 (!: 13a, 13a and 13b.

When a gentle massage is intended, the pressure oil is gradually removed from the port 25, and the second finger 13, 13a, 13a
What is necessary is to widen the interval between and 13b.

For this purpose, it is preferable to use a switching valve 30 that can provide a throttling effect.

In this embodiment, the finger 13a is arranged between the second finger staves 13.13b, but it is of course possible to have a structure with only the second finger 13.13b. The finger 5 and the second finger 13, 13b are arranged in a triangular shape.

Therefore, by adjusting the distance between the second fingers 13 and 13b, the kneading effect changes significantly.

In this embodiment, the piston/cylinder mechanism 14 is provided between the first fingers 3 and 11a, but the spacing between the letter parts 2, 2 is changed, and the piston/cylinder mechanism 14 is provided between them. You may also do so.

Thus, according to the present invention, the character parts are provided on both sides of the base, one finger is arranged on one character part, and at least two fingers are arranged on the other character part, and each character part is provided with one finger and at least two fingers are arranged on the other character part. The fingers of the plurality of sides are arranged oppositely, and are provided with an operation mechanism that operates the fingers so that these opposing fingers move towards and away from each other, and the relative spacing of the fingers on the plurality of sides is variable. Since it is equipped with a control mechanism, the massager can achieve the same massage effect as the actual massage with fingers, and the massager can massage for a long time without getting tired.

Furthermore, the patient himself/herself can operate this unit.

Moreover, since the spacing between the fingers on one side can be adjusted, it is possible to change the massaging brushes appropriately depending on the area to be treated, such as the arm or thigh.
