Description

[Detailed description of the invention] The present invention is a hand-type or pillow-type pine surger equipped with a pair of tilted oscillating massaging wheels, and more specifically, the interval between the left and right pair of massaging wheels is adjustable.
The present invention relates to a pine surger equipped with a device whose adjusted position does not easily change due to load.

It is already known that a small hand-type or pillow-type pine massager is equipped with a pair of oscillating massage rings, the distance of which can be adjusted depending on the area of use, such as the nape of the neck, shoulders, or lower back. It is being The adjusting means is such that the rubbing ring is movable in the axial direction of the rotating shaft that drives the pair of rubbing wheels, and the base of the rubbing ring is allowed to freely rotate. one end of each arm is engaged, and the other end of the arm is threaded from the center to both sides of a helical shaft with opposite spiral directions, and the spiral shaft is rotated to the right or left. A mechanism is used in which the left and right rubbing wheels move outward or inward, respectively, by rotating the wheel. This mechanism has the advantage that the left and right kneading wheels can be simultaneously moved in opposite directions by rotating the screw shaft to the right or left, but it is not possible to directly rotate the screw shaft. Therefore, when adjusting the distance between the left and right rubbing wheels, the operating handle must be rotated quite a lot, and furthermore, during use, the pressing force of the rubbing wheels on the human body and the shaking of the rubbing wheels are large. This method has the disadvantage that the adjusted spacing between the rubbing wheels gradually changes due to factors such as vibration and shaking of the pine surge device itself.

The present invention has been made with the aim of improving the above-mentioned disadvantages, and the spacing between the rubbing wheels can be adjusted by a small amount of rotation of the operating handle. To provide a pine surge device equipped with a mechanism that does not easily change the spacing between the rubbing wheels.

The drawings showing the embodiments of the present invention will be described below. FIG. 1 shows a hand-type pine massager, in which 1 is the main body of the pine massager, 2 is a handle, and 3 is the working part of the massaging ring. As shown in FIG. 2, a motor 4 is installed inside the pine surge device body 1
From reducer 5 and worm 6, worm gear 7
The main shaft 8 is provided with a main shaft 8 that is gently rotated through the main shaft 8, a key-shaped protrusion 9 is fixedly provided over almost the entire length of the effective part of the main shaft 8, and a pair of left and right inclined eccentric rubbing wheels 10,
10 is fitted to the main shaft 8 at its base,
It is designed to be swung as the main shaft 8 rotates and to be movable in the axial direction of the main shaft 8. One end of an arm 12 is fitted to the base of each of the rubbing wheels 10, 10 via a pairing 11, and the other end of both arms 12, 12 is connected to the main shaft 8.
A helical shaft 1 having spiral portions 13 and 14 disposed in parallel with each other and having spiral portions 13 and 14 in opposite directions from the center to both sides.
When the screw shaft 15 is rotated left or right, both arms 12, 12 are moved in opposite directions, thereby causing the rubbing wheels 10, 12 to move in opposite directions.
10 intervals W can be adjusted.

The present invention provides a pine surger in which the distance W between the left and right pair of rubbing wheels 10, 10 is adjusted by rotating the screw shaft 15 as described above. The small diameter gear 16 is fixed to the large diameter gear 17, and the small diameter gear 16 is meshed with the large diameter gear 17, and an operating lever 19 is provided at the outer end of the shaft 18 of the large diameter gear 17, so that the rotating operation of the operating lever 19 is controlled by the large diameter gear. The configuration is such that the speed is increased and transmitted to the small diameter gear 16 via the gear 17, and furthermore, a mechanism for preventing rotation of the threaded shaft 15, for example, the large diameter gear 1, is provided in the transmission section to the threaded shaft 15.
A braking device comprising a braking wheel 20 provided on the shaft 18 of 7, and a braking band 21 that is in sliding contact with a part of the outer peripheral surface of the braking wheel 20 and whose pressure contact force to the braking wheel 20 can be adjusted. This prevents the screw shaft 15 from rotating during use.

As a means for adjusting the braking force of the above-mentioned brake band 21, it is preferable to attach a spring 22 to the free end 21' of the brake band 21 and connect the end of the spring 22 to the adjusting screw 23. The braking force generated by the braking band 21 can be applied without any trouble to the above-mentioned rotation operation of the operating lever 19, and can be applied to vibrations during use.
Depending on the above-mentioned factors such as the horizontal movement component of 0 and 10, it is desirable to set the screw shaft 15 to such an extent that it will not rotate.

Furthermore, the rotation prevention mechanism for preventing idle rotation of the screw shaft 15 during use is not limited to the above-mentioned braking means;
For example, as shown in FIGS. 4 and 5, the inner end of the handle 24 of the operating lever 19 is brought into elastic contact with the side wall 25 of the pine surge main body 1 using a leaf spring 26. , holes or depressions 27 are arranged in parallel along the rotation locus of the handle 24, and the lever 19 is rotated to adjust the pair of kneading wheels 10, 10 to a desired spacing. Locking means by fitting the ends into holes or recesses 27 may also be employed.

Note that the operating lever 19 may be lever-shaped as shown, or may be circular.

As described above, the pine surger according to the present invention has a pair of left and right rubbing wheels 1 which are oscillated by the rotation of the main shaft 8 and are attached movably in the axial direction of the main shaft 8.
0 and 10 are provided in parallel with the main shaft 8, and the ends of the arms 12 and 1 are screwed together with a spiral shaft 15 provided with spiral portions 13 and 14 in opposite directions from the center toward both sides.
2, in which the spacing W between the pair of rubbing wheels 10, 10 can be adjusted by rotating the screw shaft 15;
A small diameter gear 16 is fixed to the end of the large diameter gear 17.
A control lever 19 is provided at the outer end of the shaft 18 of the large diameter gear 17, and the large diameter gear 1
A rotation prevention mechanism is provided on the shaft 18 side of 7 or on the screw shaft 15 side to prevent the screw shaft 15 from rotating freely during use.
The adjustment operation of the interval W between 0 and 10 can be done skillfully and in a short time, and the interval W between the rubbing wheels 10 and 10, which is adjusted before use, does not change during use, and a comfortable pine surge effect can be achieved. You can continue. Therefore, the present invention is conveniently used as a compact pine surger such as a hand type or a pillow type.
