[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a massaging machine for lower limbs, which is used by being placed on a floor surface.

[0002]

2. Description of the Related Art A massage machine of this type is known, for example, from Japanese Utility Model Publication No. 2-68841. There, the eccentric cam causes the entire base plate to vibrate along the plate surface. This kind of unipotent massage machine got used to stimulation in a short time, and helped that the strength and cycle of stimulation were uniform.
It is inevitable that the stimulus becomes monotonous.

In order to avoid such disadvantages, it is effective to apply different types of stimulation to the same treatment site at the same time, as seen in, for example, the composite type massage machine of Japanese Utility Model Laid-Open No. 58-108835. Yes, the massage effect can be improved. There, the motor power is output to the drive shaft via a speed reducer, a large number of acupressure bodies provided along the drive shaft are driven in and out by an eccentric cam, and a rotor weight is attached to the rotor shaft of the motor to vibrate. Is being generated. In other words, it takes a form in which a vibration stimulus is simultaneously given while applying a pressure stimulus with the acupressure body.

[0004]

A compression type, a friction type, a tapping type, a kneading type, and a vibration type are known as basic stimulating motions of a mechanical massage machine. The difference between these types is
It is only the difference in the direction, speed, area, and cycle of the deformation of the treatment site, and all of them only locally deform and stimulate the treatment site. Therefore, even if it is a compound type massage machine, the biggest problem is that the application is limited for the purpose of improving blood circulation and enhancing metabolism by treating muscles and skin as treatment objects.

An object of the present invention is to obtain a massage machine which can stimulate not only muscles and skin but also joints and muscles of the lower limbs, and can be applied to a wide range of applications such as rehabilitation of the lower limbs and maintenance of exercise capacity. Another object of the present invention is to obtain a massager that exerts a high degree of massage effect like a composite massager.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 2, a massager comprises a main body case 1 fixed on a floor, a base plate 2 arranged on the upper part of the main body case 1, an oscillating mechanism and a tilting turning mechanism arranged in the main body case 1. And so on. The main body case 1 is composed of a main case 1a whose upper and lower surfaces are open, and a bottom cover 1b which closes the lower surface opening of the main case 1a, and is placed on the floor via four rubber legs 3 fixed to the bottom cover 1b. .. A lower part of the front surface of the main case 1a is projected forward, and control parts such as a power switch 4 and a pilot lamp 5 are mounted on the projecting wall (Fig. 5).
reference).

The base plate 2 is formed in the shape of a square lid that opens downward, and is arranged so as to cover the upper opening of the main case 1a from above. The base plate 2 has a sufficient size for placing the foot, lower leg or upper leg, and a rubber sheet 6 is attached to the upper surface wall thereof as shown in FIG. The base plate 2 is supported in a front downward inclination posture by a drive mechanism described later.

In FIG. 2, the oscillating mechanism and the tilting and swiveling mechanism use one motor 8 as a common drive source, and both are mounted on a support plate 9 facing the inner surface of the base plate 2.
The vibration generating mechanism is composed of a motor 8 and a rotary weight 11 fixed to the lower end of a rotor shaft 10 that penetrates the motor 8 in the vertical direction.
Due to the moment of inertia of the rotary weight 11 that rotates at the same speed as the rotor shaft 10, vibration in all directions parallel to the support plate 9 is generated. As shown in FIG. 4, the rotary spindle 11 has a rotor shaft 10
The arm portion 11a is fixed to the arm portion 11a, and the crescent-shaped weight portion 11b provided at the tip of the arm portion 11a.

The tilting and swinging mechanism includes the motor 8, a speed reducer 13 connected to an upper end of a rotor shaft 10 thereof, and a speed reducer 1.
The inclined shaft 15 fixed to the output shaft 14 protruding to the upper surface of
And a bearing 16 fixed to the center of the inner surface of the base plate 2 to support the upper end of the tilt shaft 15. In FIG. 1 and FIG. 3, the tilt shaft 15 has a hole 18 that is fitted onto the output shaft 14 on one side of the lower surface of a horseshoe-shaped connecting block 17, and a drive shaft portion 19 projects from the upper surface of the connecting block 17. The central axis Q of the drive shaft portion 19 is provided at a position eccentric with respect to the central axis P of the hole 18 and is inclined in a downward conical shape.
20 is a screw for fixing the connecting block 17. The speed reducer 13 decelerates the rotation speed of the rotor shaft 10 using a group of spur gears and outputs the decelerated rotation speed to the output shaft 14. Reducer 13 and motor 8
Are integrated with bolts (not shown), and the speed reducer 13 is fastened and fixed to the support plate 9, so that the vibration generating mechanism and the tilting and swiveling mechanism are entirely supported by the support plate 9.

In order to efficiently transmit the vibration energy generated by the rotary weight 11 to the base plate 2, the support plate 9 is supported in a floating manner with respect to the main body case 1. Specifically, as shown in FIGS. 2 and 3, four elastic bodies 2 are provided on the lower surface of the support plate 9.
1 is mounted, and these elastic bodies 21 are supported by a base 23 via leg pieces 22 that can be bent and deformed vertically. As the elastic body 21, a commercially available vibration-proof rubber was used. Further, the base 23 is supported by the bottom lid 1b via the four anti-vibration rubbers 24. Elastic body 2
The 1 and the leg pieces 22 help to vibrate the support plate 9 and the base plate 2 comfortably. The anti-vibration rubber 24 is provided to block the transmission of vibration to the main body case 1 side.
In the state of floating support, the support plate 9 is inclined forward and downward in parallel with the upper opening surface of the main case 1a.

As described above, the base plate 2 is supported by the inclined shaft 15 via the bearing 16. Therefore, the entire base plate 2 can rotate with respect to the tilt shaft 15 at an arbitrary axis turning position. In order to prevent this free rotation and keep the base plate 2 directly facing the user, the support plate 9 and the base plate 2 are connected by an elastically deformable check body 26. The check body 26 is made of a rubber band, and has one end fixed to the four corners of the support plate 9 and the other end fixed to the base plate 2 in a U-shaped bent state. When the base plate 2 tilts and turns, each check body 26 can be deformed following the base plate 2, so that the check body 26 does not interfere with the tilting and turning operations.

When the load is concentrated on the peripheral edge of the base plate 2, the base plate 2 flexes and deforms toward the load point side or tends to incline by the amount of the loose clearance of the bearing 16. A rubber stopper 27 is attached along the opening edge of the main case 1a in order to regulate the amount of tilt within a range that does not hinder the movement.

Next, a usage example and operation of the massage machine will be described. The user sits on the floor, places the lower legs and upper legs aligned on the base plate 2, or puts the chair in a position facing the massage machine, and puts the foot on the base plate 2 while sitting on the chair. use. When the power switch 4 of the massage machine is turned on, the motor 8 is activated, and at the same time, the rotary weight 11 is rotationally driven to generate vibration. The vibration is transmitted to the support plate 9 via the speed reducer 13 and vibrates all the members mounted on the support plate 9. The base plate 2 supports the support plate 9 via the tilt shaft 15.
The vibration is inherited from the whole, and the whole vibrates and transmits the vibration to the lower limbs that come into contact with the plate surface.

The rotational power of the motor 8 is reduced by the speed reducer 13 and transmitted to the output shaft 14, and the entire tilt shaft 15 is output to the output shaft 1.
Drive with 4 At this time, since the center axis Q of the drive shaft portion 19 is eccentric to the center axis P of the output shaft 14 and is inclined, the drive shaft portion 19 has a constant inclination posture with respect to the center axis P. Rotate around it while maintaining. At this time, the bearing 16 is provided to absorb the relative displacement between the drive shaft portion 19 and the base plate 2 without difficulty. Due to the rotation of the drive shaft portion 19, the base plate 2 pivots around the central axis P while changing the inclination direction in all circumferential directions. Therefore, a lower limb, for example, a foot on the base plate 2 accompanies the base plate 2 and tilts and turns, and the joint of the ankle rotates by this movement, and at the same time, the tendons and muscles around the joint expand and contract. Therefore, the user receives a massage effect by vibration and stimulation of joints and muscles by tilting and turning of the base plate 2 at the same time. Furthermore, as the posture of the lower limbs placed on the base plate 2 changes continuously,
Since the direction, strength, and position of the vibration transmitted from the base plate 2 to the lower limbs change periodically, it is possible to prevent the stimulation acting on the lower limbs from becoming monotonous, and to enhance the massage effect.

FIG. 6 shows another embodiment of the massage machine in which the arrangement of the vibrating mechanism and the tilting and swiveling mechanism is changed. In this case, the both mechanisms are driven by the dedicated motors 8A and 8B, respectively, so that both mechanisms can be driven simultaneously or only one of them. Specifically, the support plate 9, the elastic body 21, and the leg pieces 22 in the above-described embodiment are omitted, and the motor 8A for the tilting and turning mechanism is attached to the base 23.
Further, the motor 8B for the vibration mechanism is fixed to the inner surface of the base plate 2, and the rotary weight 11 is fixed to the rotor shaft 10. The check body 26 was mounted between the main case 1a and the base plate 2.

In addition to the above, for example, electromagnetically operated clutches are respectively interposed between the rotor shaft 10 of the motor 8 and the rotary weight 11 and the speed reducer 13, and the states of the clutches are switched to perform individual drive and full drive. It can be carried out. Similarly, the drive mode can be selected by replacing one of the clutches with a one-way clutch and rotating the motor 8 in the forward and reverse directions. The rotary weight 11 may be arranged between the motor 8 and the speed reducer 13 or between the speed reducer 13 and the base plate 2. The leg piece 22 and the anti-vibration rubber 24 in the embodiment can be omitted. In this case, the support plate 9 is supported by the main body case 1 via the elastic body 21. The elastic body 21 may be formed by a coil spring, or may be formed by combining a rubber block and a spring. The check body 26 may be formed by a tension spring or a chain. The bearing 16 does not have to be a ball bearing.
