[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a massage machine, and more particularly to a massage machine having a roller massage function and a fir function.

[0002]

2. Description of the Related Art Conventionally, there has been a massager in which a plurality of rollers are mounted on an outer peripheral surface of a main shaft arranged in a horizontal direction, and the main shaft is rotated by driving a motor to knock a foot or a calf placed on the rollers. Are known. There is also known a massager in which a pair of disc-shaped massage massage members are attached to a main shaft arranged in a horizontal direction. The fir massage member has opposite surfaces inclined in opposite directions.
When the power is turned on, the fir massage member rotates together with the main shaft by the driving of the motor, and the fir action is performed by the opening and closing movement of the opposed surface of the inclined fir massage member.

[0003] Further, there is known a massage machine having a roller and a fir massage member, and having two functions of a roller massage and a fir.

[0004]

The function of the massager provided with the above-mentioned conventional roller and fir massager is improved over that of a single-function massager. But,
In this type of massage machine, there is no one that can adjust the interval between the massage massage members, and an appropriate massage effect may not be obtained depending on the user.

Therefore, there is a technical problem to be solved in order to provide two types of massage functions, fir and tapping, and to adjust the distance between the fir massage members for the convenience of the user. Aims to solve the problem.

[0006]

Reference numerals 20 and 20 denote fir massage members,
The outer peripheral surfaces of the sliding cylinders 21 and 21 loosely fitted to the main shaft 7 are inclined with respect to the main shaft 7, and the outer peripheral surfaces are provided with ball bearings 22 and 21.
22, two resin rings 23, 24, 23, 2
4 is mounted so as to freely rotate. Rubber pressing pieces 25, 25 having projections provided at appropriate intervals are connected to two resin rings 2.
3, 24, 23, 24, and press plate 26,
The position of the rings 23, 24, 23, 24 is determined by 26.

The lead screw 2 disposed in the main shaft 7
The guide members 28, 28 screwed into the shaft 7 are connected to the sliding cylinders 21, 21 through key grooves 29, 29 formed in the main shaft 7. FIG. 4 is an exploded view of the mechanism unit 2. The main shaft 7 penetrating through the gear case 10 is a hollow pipe.
Reference numeral 29 denotes a keyway which is opened from both left and right ends toward the center. Sliding cylinders 21 and 21 of fir massage members 20 and 20
Has an inner diameter substantially equal to that of the main shaft 7, and can slide along the main shaft 7. The lead screw 27 accommodated in the main shaft 7 is provided with thread portions 30, 30 which are opposite to each other in a left-right direction. The guide members 28, 28 fixed to the inner ends of the sliding cylinders 21, 21 have a slide key 31 and a screw receiver 32, and are provided on the inner end faces of the sliding cylinders 21, 21 as shown in FIG. Into the notch 33. Then, the slide key 31 is inserted into the key groove 29 of the main shaft 7, and the screw portion 30 of the lead screw 27 is screwed into the screw receiver 32. And
Pressing plates 34, 34 shown in FIG. 4 are screwed to the end faces of the sliding cylinders 21, 21, and the guide members 28, 28 are fixed to the massage members 20, 20, respectively.

Next, the massage rollers 13, 13 are inserted into the main shaft 7. The engaging portions 35 of the massage rollers 13 are cut out in the vicinity of both ends of the key groove 29 of the main shaft 7, and although not shown, the engaging portions 35 are engaged with the outer end plates 15 of the massage rollers 13. An engagement piece that fits into the engaging portions 35, 35 is provided to fit in the engaging portions 35, 35, and the main shaft 7
The massage rollers 13, 13 are fixed to this. Then, the bearings 37, 37 of the resin caps 36, 36 are inserted into the lead screw 27,
Are projected, and the outer cylindrical portions 38 of the caps 36 are mounted on the end of the main shaft 7. 39,39
Numeral denotes a cap-shaped thrust bearing fixed to a predetermined position of the upper and lower cases 3 and 8, and is mounted on the caps 36 and 36. Reference numeral 40 denotes a brake plate fixed to the left end of the lead screw 27, and a rubber ring 41 is attached to the outer peripheral portion.

As shown in FIG. 1, the thrust bearing 3 is attached to bearing fixing portions 9, 9 formed on the lower case 3 and the upper case 8.
The mechanism part 2 is attached by fitting the components 9 and 39 together. A solenoid 42 is fixed to the left side of the left bearing fixing portion 9, and the brake plate 40 is inserted into an inner peripheral portion of a braking piece 43 attached to a plunger (not shown) of the solenoid 42.
When the solenoid 42 is energized, the brake piece 43 is pulled downward and pressed against the brake plate 40 to prevent the lead screw 27 from rotating.

When the motor 4 is energized, the worm gear 12
The main shaft 7 is rotated via the worm wheel 11.
Sliding cylinders 21 and 21 in which slide keys 31 and 31 are engaged with key grooves 29 and 29 of the main shaft 7;
13 rotates in conjunction with the main shaft 7. At this time, when the solenoid 42 is off and the brake is released, the lead screw 27 screwed to the guide members 28 shown in FIG. 5 rotates in conjunction with the whole massage members 20. Here, when the solenoid 42 is turned on to brake the lead screw 27, the guide members 28, 28 rotating together with the main shaft 7 are respectively sent on the lead screw 27 in opposite directions, and expand or approach depending on the rotation direction of the main shaft 7. The entire fir massage members 20, 20 can be moved to freely adjust the distance between each other. The above-described forward / reverse rotation of the motor 4 and ON / OFF of the solenoid 41 are performed by operating switches 44, 44... Disposed on the operation switch board 6.

[0015] Cylindrical covers 45, 45 are provided on the outer end plates of the massage massage members 20, 20, and when the distance between the massage massage members 20, 20 is minimized as shown in FIG. , 45 and massage roller 1
No gap is formed between the inner end plates 16 and 16 of the third and third plates 13. FIG. 3 shows the fir massage members 20 and 2.
0 indicates the maximum state, and 46 and 46 indicate the sliding cylinder 2
It is a cylindrical portion extending inward from 1,21. Cover portions 47, 47 capable of accommodating the cylindrical portions 46, 46 are formed on both left and right sides of the gear case 10, and the cylindrical portions 46, 46 are provided even when the distance between the fir massage members 20, 20 is maximized.
There is no gap between 46 and cover portions 47,47.

Therefore, no matter where the fir massage members 20, 20 are located in the movable range, the main shaft 7, the worm wheel 11, and the like are not exposed, and there is no possibility that the cloth cover or the human body is pinched. The present invention can be variously modified without departing from the spirit of the present invention, and it goes without saying that the present invention extends to those modifications.
