Description

[Detailed Description of the Invention] The present invention relates to a multifunctional treatment device that combines the function of a massager that operates at high speed with vibrations, and the treatment functions of hitting, massaging, and acupressure that operate at low speed in reciprocating motion.〇Generally , a mechanism of a massager that vibrates at high speed, and a tapping,
Treatment mechanisms that use low-speed reciprocating motions, such as massaging and acupressure, are usually configured separately due to their functionality, but in order to incorporate them into one device and obtain multifunctionality, one of them must be based on vibration. However, this kind of multifunctional treatment device has not been developed at all, and it has been said that it is impossible because the other is a treatment device based on low-speed reciprocating motion. Modern people have sufficient knowledge that each treatment device has different therapeutic effects and that it is desirable to select the treatment device depending on the physical condition. The development of a multifunctional treatment device that performs various treatment functions by adding some attachments to a single treatment device is awaited. When talking about such multifunctional treatment devices, the important point is that power can be transmitted from the same drive source to a mechanism that can adapt to each function, that the operation of one mechanism is not affected by the other mechanism, and that it is possible to do so as much as possible. It has a mechanism that can be shared, and the overall structure is simple compared to its multifunctionality.The inventor previously developed a massager that vibrates at high speed and a treatment device that reciprocates at low speed. We propose a multifunctional treatment device that can be used for both massaging, acupressure, and other treatments by changing the attachments, and has a simple configuration that prevents the functional operation of one from affecting the other. did.

The reciprocating motion means 100 stores power transmitted through the second one-way clutch 800 during the reciprocating motion by the rocking element 750, and performs intermittent motion. The device is equipped with a mechanism for releasing the stored force to the treatment element 200. Part of the mechanism is the above-mentioned cam follower 140, the cam 130, and the reciprocating element 150, but in this embodiment, the mechanism that accumulates the stored force by the operation of the reciprocating element 150 is the one described above.

and a tension coil spring 1008 that elastically supports the lock lever 1007. Therefore, at the same time as the setting lever 1003 is pulled up, the lock lever 1007 is operated to selectively lock the lock pawl 1006 to the lock portion 1004, thereby selectively setting the degree of the stored force of the compression coil spring 191. Old man, lock lever.
If only 1007 is operated independently, the setting lever 1003 is disengaged and the stored force is released, as described above. Note that the reciprocating means 100 includes a reciprocating element 150.
Rod 1510 has a cushioning effect when the
A rubber cushion member 1009 may be installed in the portion.

Next, the operation for obtaining the striking effect and the pine surge effect in the above embodiment will be explained. First treatment table 220
, place it on the pedestal 210, insert the set bottle 230 into the set hole 217, and in this state, tighten the clamp lever 24.
0, move the clamp roller 24 to the clamp Izxs.
2 and fix the treatment table 220 to the base 210.

Therefore, when the motor 400 is rotated in one direction, the one-way clutch 600 remains in an unengaged state with respect to that direction of rotation. In this situation, the linking means 500
In other words, when clutches 510 and 5-
40 is maintained, the rotation of the motor 400 is thereby transmitted to the rotating element 710, causing the crank operating element 720 to eccentrically rotate. As a result, each swinging element 750 swings via the arm portions 722 and 723, but only one direction of the swinging elements 750 swings.

It is transmitted to the cam 130 via the opposite clutch 800. That is, when the clutch plate 81O rotates in the direction of the arrow, it guides the roll clutch 811 between the outer periphery of the cam 130 and the suppressor 815, so that the clutch plate 810 and the cam 130 are frictionally engaged, and the cam 130 is rotated. When the swinging element 750 moves back, it moves against the leaf spring 8I'4.
Since the roll clutch 811 is led out from the suppressor 815, the frictional relationship between the clutch plate 810 and the cam 130 is released, but at this time, the clutch plate 820 and the cam 1
30, when the cam 130 tries to reverse, the roll clutch 825 is guided to the inclined surface 826, and frictional engagement is achieved.
The reversal of can be prevented.

However, since the clutch plate 820 is fitted into the cap-shaped accommodation housing 120, although the protrusion 823 has the effect of stopping rotation 9, there is some play, so the driving force applied to the cam 130 is When the cam 130 is momentarily lost, the force of the spring 191 attempts to reverse the cam 130, but due to the action of the spring 829, the clutch v
Since the i820 is prevented from rattling, in that sense, the cam is also prevented from rotating in reverse by minute forces.

When the cam 130 operates intermittently and rotates once, the cam follower 140 moves from the cam guide 131 to the step 132, where the cam follower 140 falls down, and the cam follower 140 moves from the cam guide 131 to the step 132.
During the rotation process, the spring 191 (or spring 193 in some cases) is gradually compressed, and the stored force applied to the reciprocating element 150 is released. This causes the reciprocating element 150 to move rapidly, raising the striking element 200 and
Tap the affected area from the back side of the flexible sheet 223. Also, when using this device as a vibrator,
The motor 400 may be rotated in the opposite direction by a switching operation or the like. In this case, the connection of the linking means 500 is released. As a result, the rotation of the motor 400 is transmitted to the eccentric operating element 310 via the clutch 600, and is transmitted to the pedestal 21 as eccentric vibration via the bearing 320.
0 can be communicated. Thus, the treatment table 220 attached to the pedestal 210 is vibrated at a high frequency (a period of 400).

Moreover, if it is expected that the treatment table 220 attached to the base 210 will also provide a vibrator effect while exerting a hitting effect, the following may be done. First, the rotation direction of the motor 400 is maintained in the direction in which the engagement of the clutch 600 is maintained, and the coupling means 500 is operated,
It is only necessary to achieve cooperative engagement between friction clutches 510 and 540.

As a result, high-frequency vibrations can be applied by the treatment table 220 applied to the affected area while hitting the affected area with the hitting element 200.

Note that by removing the treatment table 220 from the base 210 and attaching another attachment, the kneading effect may be exerted using the driving force from the hitting element.

In this case, if high-frequency vibrations are simultaneously applied to the base 210 in the same manner as described above, a combined effect of applying light vibrations as well as the kneading effect can be obtained.

As described in detail above, the present invention includes a plurality of reciprocating means arranged in parallel with each other, a treatment element provided in the reciprocating means, and a vibration means arranged in parallel with the reciprocating means to generate pine surge vibration. a rotary drive means for switching between forward and reverse rotation for applying driving force to the reciprocating means and the vibration means; a first one-way clutch disposed in the transmission system between the rotary drive means and the vibration means to connect the transmission system with respect to one-way rotation; Conversion means for converting the rotation of the drive means into a reciprocating motion in a transmission system to the reciprocating means, and converting the rotation in one direction of the reciprocating motion into a reciprocating motion It is equipped with a second one-way clutch that transmits the motion to the reciprocating means, so that although the combination structure is relatively simple, it combines a massager that vibrates at high speed and a treatment device that reciprocates at low speed. It can be used for both purposes and has the excellent effect of being able to achieve both purposes at the same time if necessary.
