Description

Description: TECHNICAL FIELD The present invention relates to an electric massage machine, and more particularly to a massage machine in which a treatment element performs acupressure operation and kneading operation.

[Background Art] In an electric massage machine, not only kneading and kneading of fir tree loosening but also acupressure can be performed by rotating as in Japanese Utility Model Publication No. 57-87738. There is one in which a pair of eccentric tilted wheel wheels are attached to a driven rotating shaft. The rotation of the inner ring that rotates together with the rotating shaft and the outer ring that is freely rotatably arranged on the outer periphery of the inner ring cause a finger-pressure action and an eccentric component with respect to the rotating shaft due to the rotation. The kneading operation is performed by the tilt component. However, in this one, the acupressure action due to the eccentric component is not clear because the outer diameter of the baffle ring is large. However, there is a problem that it is impossible to secure a sufficient stroke. In the case of performing acupressure by linearly reciprocating the treatment element as shown in JP-A-53-13577, the acupressure operation of pressing a certain point can be performed, but the massage is performed. The kneading operation cannot be performed. As shown in Japanese Patent Laid-Open No. 59-211452, in the case where the treatment element is provided at the tip of the rotating shaft that performs the axial movement and the rotating movement, the acupressure operation and the kneading operation can be obtained. However, the one shown here is inevitably large in size, because the power is transmitted from the single motor to the mechanism for each movement through the power transmission paths of the different systems. It is difficult to configure the device so that it can be moved in the longitudinal direction of the bed so that the treatment position can be changed.

[Object of the Invention] The present invention has been made in view of the above points, and an object of the present invention is to perform both an acupressure operation and a kneading operation as an effective mechanism. It is to provide a massage machine that can be compactly assembled.

DISCLOSURE OF THE INVENTION The present invention is, however, a massage machine in which a treatment element is provided at the tip of a rotating shaft that performs a rotating motion and an axial motion, and the rotating shaft includes a feed screw portion and a spline. With a groove that runs in the axial direction, and the rotation of the rotating shaft is restricted by the engagement of the feed nut that is driven to rotate by the motor and that is screwed into the feed screw portion, and the groove. An eccentric rotary motion about the axial direction of the rotary shaft from the rotary force transmitted from the motor to the feed nut to the treatment element at the tip of the rotary shaft. It is characterized in that it is provided with a rotary motion generating unit for generating rotary motion. The eccentric rotary motion of the treatment element can be obtained by revolving the rotation shaft itself around a certain axis, or the treatment element can be eccentrically provided on the rotation shaft that rotates around the rotation axis. It can also be obtained by providing a protrusion at a position away from the center of motion.

The present invention will be described in detail below with reference to the illustrated embodiments.
FIG. 2 and FIG. 2 show a bench-shaped treatment table equipped with a massager unit according to the present invention. This treatment table
Legs 5 at both ends whose upper surfaces are cushion portions 51, respectively
0, 50 and a pair of side frames 52 connecting the legs 50, 50,
52 and 52 form a frame, and a cover 53 is provided on the upper surface.
The guide rails 55 are attached to the facing surfaces of the side frames 52, 52, respectively. The guide rail 55 guides the travel of a self-propelled block including a pair of massager units A and A. Four statistical rollers 61 projecting from the left and right of the self-propelled block travel in the guide rail 55. To do. The traveling of the self-propelled block is performed by the pinion 63, which is rotationally driven by the gear motor 62 provided in the self-propelled block, meshing with the rack 56 attached to the guide rail 55.

Both massager units A and A have the same structure. As shown in FIGS. 3 and 4, the massaging device 1, the housings 35 and 36 that are vertically combined, and the both housings 35 and 36 are vertically arranged. The rotary shaft 2, the motor 3, and the gear members incorporated in the housings 35 and 36. A rotary shaft 2 having an eccentric cam 20 at its upper end and supporting a substantially conical treatment element 1 on the outer periphery of the eccentric cam 20 via a bearing 10 has its upper portion rotatably supported by a bearing 37 of a housing 35. Further, it is slidable in the axial direction, and a pair of upper and lower circumferential key grooves 21 and 23 and an axial key groove 22 connecting the both key grooves 21 and 23 are provided in the upper part. And a feed screw portion 24 is formed at the lower end. Both housings 35,
Within 36, the key 1 is biased by a spring 18.
9, a feed nut 17 supported by a bearing 15 and a bevel gear 16 integral with the feed nut 17 are provided, and the feed nut 17 is screwed with the feed screw portion 24 of the rotary shaft 2. The key 19 is a key groove 21, 2 on the rotary shaft 2.
2, 23 are engaged.

Motor 3 fixed to the outer surfaces of both housings 35, 36
Has a bevel gear 14 whose output shaft meshes with the bevel gear 16.
Is fixed, and the rotation of the motor 3 is controlled by both bevel gears 14, 1
The feed nut 17 is rotated via 6. Further, the feed nut 17 is provided with pins 43 and 44 that engage with pins 41 and 42 projecting from the upper and lower peripheral surfaces of the feed screw portion 24 of the rotary shaft 2. A spring 39 is arranged between the lower end of the rotary shaft 2 and the mounting frame 38 fixed to the housing 36, and the rotary shaft 2 includes the spring 39.
Is urged upward by.

In the massage machine unit A, if the motor 3 is rotated in the state shown in FIG. 4,
Since the rotation of the feed nut 17 is transmitted by the engagement of the pins 41 and 43, the rotary shaft 2 in which the key 19 is positioned in the key groove 21 rotates around the shaft and the eccentric treatment element 1 is rotated. It is rotated around the axis of the rotary shaft 2. Then, within one rotation of this rotation, the key 19 is moved from the key groove 21 to the key groove 22 in the axial direction by the upward bias of the rotating shaft 2 by the spring 39, so that the rotating shaft 2 is prevented from rotating. First, the rotation of the feed nut 17 moves the rotary shaft 2 in its axial direction, and causes the treatment element 1 to project upward.
When the key 19 reaches from the key groove 22 to the key groove 23 by this upward movement, the key 19 moves to the key groove 23 and the pins 42 and 44 are engaged with each other, so that the rotary shaft 2 is again rotated. The rotation is started around and the treatment element 1 is rotated. The eccentric treatment element 1 performs a kneading operation on the human body through the cover 53 by this rotation.

If the rotation direction of the motor 3 is reversed from this state,
At this time, since the load of the human body applied to the massaging device 1 exceeds the urging force of the spring 39, at the time when the key 19 reaches directly above the key groove 22, the rotary shaft 2 lowers and the key 19 is placed in the key groove 22. Move to. Therefore, thereafter, the rotation shaft 2 starts to move downward by the rotation of the feed nut 17, and this downward movement is performed until the key 19 enters the key groove 21.

That is, the treatment element 1 performs a vertical movement in the vertical direction and a rotational movement at the upper and lower dead points of the linear movement. The linear movement applies acupressure to the human body, and the rotational movement causes the human body to move. The function of kneading is performed. And this massage machine unit A
Since it is provided on the self-propelled block as described above,
The massage of shiatsu and kneading can be performed on any part of the human body lying on a bench-shaped treatment table from the shoulder to the waist. The pins 43 and 44 are the pins 41 and 42.
In order to prevent them from inadvertently interfering with each other, each of them is made foldable in the direction opposite to the rotation transmission direction and its length is set. Further, assuming that the key grooves 21, 22, 23 are smoothly continuous, these key grooves 21, 22,
2, 23 and the key 19 may constitute a positive cam.

FIG. 6 shows a control circuit of the motor 3 using the timer T in the above embodiment. When the required time elapses, the time delay contact t of the timer T inserted in series with the relay R switches, so the relay R switches the contacts r ₁₁ and r ₁₂ to reverse the rotation direction of the motor 3. Let

FIG. 7 shows another embodiment. In this, the treatment element 1 is attached to the upper end of the rotating shaft 2 without eccentricity. The self-propelled block is fixed to the base plate 9, and the housings 35 and 36 and the motor 3 are movable on the base plate 9. The planetary gear 60 that meshes with the internal gear 92 provided on the base plate 9 is mounted on the base plate 9. It is formed on the outer peripheral surface of the feed nut 17 which is integral with the bevel gear 16. In addition, the base plate 9 holds a bearing 93 that supports the lower end of the feed nut 17 via a bearing 90 and an eccentric disc 91. Further, the rotary shaft 2 is provided with an axial key groove 22 in which a key 19 is provided.
And a sliding pin 95 that engages with the guide groove 94 on the base plate 9 is fixed to the lower end of the motor 3.

Now, when the motor 3 is rotated, the feed nut 17 moves the rotary shaft 2 in its axial direction, and at the same time, the mesh between the planetary gear 60 and the internal gear 92 causes the rotary shaft 2 to move. Rotates about the axis of the internal gear 92. Therefore, the treatment element 1 moves up and down by the movement shown in FIG. Shiatsu and kneading are always performed at the same time.

[Advantages of the Invention] As described above, in the present invention, the treatment element is provided at the tip of the rotary shaft that performs the rotary motion and the axial motion, and the finger pressure is applied by the axial motion of the rotary shaft. In order to obtain the motion, a local (pot) effective acupressure motion can be performed, and a kneading motion for a portion surrounding the local can also be obtained by the rotational motion of the rotary shaft, and a single In order to generate the rotary motion in the rotary motion generating unit from the feed nut that is rotationally driven in the reciprocating linear drive unit that causes the motor to perform the rotary motion and the axial motion. In addition, it is possible to compactly combine the mechanism section that performs the rotational movement and the axial movement,
Further, since the stroke of the axial movement can be freely selected depending on the length of the feed screw portion of the rotary shaft, the stroke can be easily set to obtain an appropriate acupressure operation.
