Description

[Detailed Description of the Invention] The present invention is capable of performing a compound kneading action using two types of kneading tools.
Furthermore, the present invention relates to a pine surge machine that can perform different massaging actions with one of two types of massaging tools, if desired.

A pair of kneading wheels are tilted toward each other, and one massager is placed at an eccentric position.
A pine surge machine attached to a rotating shaft of a book is already known.

In this type of pine surge machine, as shown in Fig. 1, A, 8, and 8, the working distance between both kneading wheels 1 and 10 is the widest when the smallest radius part of the eccentric kneading wheel 1 is in contact with the human body 3 (Fig. A). As the rotary shaft 2 rotates, the distance between them gradually decreases, and the amount of protrusion toward the human body gradually increases, resulting in a loss, and at the time when the maximum radius portion of both kneading wheels 1.1 acts on the human body. The amount of protrusion becomes the maximum, and the distance between the two kneading wheels 1.10 becomes the minimum.

After this point, the protruding amount of the kneading ring 1.1 decreases and the interval between the two kneading wheels 1.10 increases, returning to the state shown in Fig. 1 A, and the above-mentioned kneading It is a repeated kneading motion that moves into action.

Therefore, the pine surge machine equipped with such a pair of eccentric inclined kneading wheels has a relatively monotonous kneading action, and does not provide sufficient satisfaction to the user.

For this reason, in order to improve the above-mentioned monotonous kneading operation, pine surge machines have been proposed that use two pairs of eccentrically inclined kneading wheels installed at different phases or multiple wheels.

In this multi-wheel type pine serge machine, the rotation axis is one
While rotating, the kneading action by the pinching action of the kneading wheel and the pressing kneading action by the added kneading wheel are performed, and the monotony mentioned above is considerably improved, but in principle, it is necessary to attach the kneading wheel to one rotating shaft. Since it relies on the kneading action by the eccentric inclined kneading wheel, it is not possible to expect a different pine surge effect.

The present invention provides a pine surge machine that can simultaneously provide a different kneading action in addition to the kneading action by the eccentric inclined kneading wheel described above, and can also selectively provide acupressure kneading action.

2 to 4 showing embodiments of the present invention will be explained below.

In FIG. 2, reference numeral 10 denotes a first rotating shaft, and a pair of eccentric inclined kneading wheels 11 are mounted at intervals on this first rotating shaft 10, as in the prior art.

12 is a second rotating shaft, and the second rotating shaft 12 is connected to the first rotating shaft.
are provided parallel to the rotating shaft 10, and both rotating shafts 10.1
2, one of them is selectively rotationally driven by a drive source (not shown).

Eccentric cam disks 13 and 14 are fixed to the first rotating shaft 10 and the second rotating shaft 12, respectively.
An arm 16 extending toward the rotating shaft 12 is fitted.

Further, the cam disk 14 of the second rotating shaft 12 has one end 18 connected to the pair of kneading wheels 11 through the bearing 17 in the same manner as described above.
A roughly L-shaped lever 19 extending toward the space between the levers 11 and 11 is fitted, and the end of the arm 16 is pivotally connected to the other end of the lever 19, and a massaging tool is attached to one end 18 of the lever 19 as appropriate. , for example, supports a wheel-shaped massaging tool 20.

With this configuration, when the first rotating shaft 10 is rotationally driven, the first rotating shaft 10 attached to the first rotating shaft 10
As shown in FIG. 1, the pair of eccentric inclined kneading wheels 11 starts a kneading action similar to that of a conventional kneading wheel, and at the same time, the arm 16 is moved substantially in the vertical direction by the rotation of the eccentric cam disc 130, like a crank motion. The lever 19 swings about the eccentric cam disk 14 as a pivot, and the third massaging tool 20 supported by the one end 18 of the lever 19
As shown by arrows a and b in the figure, the back and forth motion of an arcuate trajectory is transmitted.

Therefore, as shown in FIG. 3, when the minimum radius side of the eccentric inclined massage wheel 11 is located on the human body 30 side, the maximum radius side of the eccentric cam disk 13 of the first rotating shaft 10 is the extending direction of the arm 16. Place it on the opposite side and set it.
By placing the kneading tool 20 at the farthest position from the human body 30, as shown in FIG.
When the minimum radius part 1 is located on the human body 30 side, that is, when the working surface of the massaging wheel 11 moves away from the human body 30, the massaging tool 20 can be brought into a state where it most protrudes toward the human body 30.

Next, in this state, the drive of the first rotating shaft 10 is stopped,
If the second rotary shaft 12 is driven to rotate instead, the eccentric cam disc 14 rotates and the lever 19 is pivoted and the other end of the lever 19 is pivotally connected to the end of the arm 16. Furthermore, since the arm 16 can swing freely through the interposition of the bearing 15, the motion of the elliptical locus as shown in FIG. be able to.

In this case, in order to give a different effect to the kneading action by the kneading tool 20, the second rotating shaft 12 is set to rotate at a higher speed than the first rotating shaft 10 described above.
A knock-on effect can also be produced.

Next, the kneading action of the pine surge machine of the present invention constructed as described above will be explained.

When the first rotating shaft 10 is driven to rotate according to the user's preference, the eccentric inclined kneading wheel 11 attached to the first rotating shaft 10
．． 11 performs a pinching action inward from both sides of the human body as is known, and at the same time the arm 16 protrudes as described above, thereby causing the eccentric cam disc 14 of the second rotating shaft 12 to
The massaging tool 20 supported by a lever 19 that is swingably fitted in Located in the most remote location.

(See FIG. 5). When the working position of the kneading wheels 11 and 110 begins to expand outward as the first rotating shaft rotates 100 times, the arms 16 begin to return, thereby causing the kneading tool 20 to move toward the human body 30. 11.1.
1 abut against the human body 30 at a time when they are substantially parallel.

(See Fig. 6) Subsequently, the working surfaces of the pair of kneading wheels 11.11 move further outward. As the working surface moves away from the human body 30, the massaging tool 20 moves further forward, and
It actively pushes against the kneading wheel 11.
11 is located on the human body side, that is, the interval between the working surfaces of the massaging wheels 11 and 11 is the widest and the human body 30
At the point when the massaging tool 20 moves away from the human body 30, the massaging tool 20 assumes the most advanced position, and the pressing force against the human body 30 becomes maximum.

(See FIG. 7) Next, the distance between the working surfaces of the pair of kneading wheels 11 and 110 becomes smaller, and as the working surfaces gradually move toward the human body, the kneading tool 20 begins to gradually retreat,
The state shown in FIG. 6 changes to the state shown in FIG. 5, and the massaging tool 20 moves away from the human body 30.
．． The kneading action of the kneading wheel 11 becomes the strongest at the point when the kneading action by the kneading wheel 11 becomes the most relaxed, and as the kneading action of the kneading wheel 11.11 becomes stronger, the pressing force of the kneading tool 20 becomes weaker (
Repeating this action creates a pine surge effect on the human body.

Next, preferably, when the distance between the working surfaces of the pair of kneading wheels 11.11 is approximately the maximum, the first rotating shaft 10 is stopped and the second rotating shaft 12 is rotationally driven. The eccentric cam disk 14 rotates together with the second rotating shaft 12, causing the lever 19 to pivot.

However, since the other end of the lever 20 is pivotally connected to the arm 16, as the lever 19 pivots, the arm 16 swings in a pendulum motion.

Therefore, one end 18 of the lever 19 and the kneading tool 20
A turning motion of an elliptical locus as shown in FIG. 4C is transmitted to the human body, and a kneading effect different from that when the first rotating shaft is driven 100 rotations is imparted to the human body.

In the embodiment shown in FIGS. 2 to 4, the lever 19 has a substantially five-shape shape, with one end 18 supporting the massaging tool 20 and the other end pivotally connected to the end of the arm 16. However, instead of this, as shown in FIG. Also by pivotally connecting the ends of the arms 16 extending from the body, when the first rotating shaft 10 is driven, the eccentric inclined kneading wheels 11, 11 and the kneading tool 20 can be made to alternately protrude toward the human body.
In addition, when the second rotating shaft 12 is rotationally driven, the lever 19
It is possible to transmit a kneading motion along an elliptical locus as shown by the arrow d to the kneading tool 20 supported at one end of the kneading tool 20, and the present invention can be satisfied in the same way as in the embodiments described above.

As described above, the pine surge machine according to the present invention has a second rotating shaft 12 parallel to the first rotating shaft 10 on which a pair of kneading wheels 11, 11 are mounted eccentrically and inclined relative to each other. Eccentric cam disks 13 and 14 are fixed to the shaft 10 and the second rotating shaft 12, respectively, and the first rotating shaft 10
An arm 16 whose end extends toward the second rotating shaft is fitted onto the eccentric cam disc 13 of the second rotating shaft 12 via a bearing 15, and one end is fitted onto the eccentric cam disc 14 of the second rotating shaft 12 via a bearing 17. The portion 18 fits a lever 19 extending between the pair of kneading wheels 11.11, and pivotally connects the end of the arm 16 to the other end or intermediate portion of the lever 19. Since the massaging tool 20 is appropriately supported on one end 18, the first
By selectively rotationally driving the rotary shaft 10 or the second rotary shaft 12, it is possible to impart two types of kneading effects to the human body that are different from those of conventional pine massage machines.

Moreover, the kneading action when the first rotating shaft 10 is rotationally driven is as follows.
After being pinched and kneaded by the pair of eccentric inclined kneading wheels 11.11, the kneading tool 20 is used to massage the muscles effectively.

Furthermore, when the second rotary shaft 12 is rotationally driven, the kneading action by the kneading tool 20 is similar to that of a pine surgeon's thumb, and furthermore, the second rotary shaft 120 rotation speed is controlled by the first rotary shaft 10. The kneading action described above can also be changed to a beating action by setting the value to a large value.
