Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pine massager having a pair of kneading wheels built into the backrest for performing a kneading motion.

The pair of massaging wheels are installed on the drive shaft in a state in which they are tilted toward each other and are both eccentric in the same direction, and massage the back of the human body through the massaging wheel cover of the backrest. A push action is obtained from a change in the amount of protrusion of the kneading wheels toward the front, and a kneading action is obtained from their inclination to each other, and a kneading pine surge is performed by a combination of both actions.

By the way, in conventional pine surge devices, the kneading ring cover was kept at a constant tension, so it was not possible to adjust the kneading force. This made it inconvenient to use.

The present invention has been proposed in view of the above-mentioned points, and provides a pine massager whose purpose is to adjust the degree of kneading by loosening or tightening the kneading ring cover of the backrest.

Hereinafter, a chair-shaped embodiment of the present invention will be described in detail with reference to the drawings.

3 in the figure is a chair in a chair-type pine massager, and this chair 3 has a pipe-shaped frame 4, a headrest part 9 of the backrest, a backrest part 11 with a kneading ring cover 10 provided on the front side of the backrest, and a cover 12. A sitting portion 13 provided,
It is comprised of armrest parts 14 formed on both sides of a sitting part 13.

Reference numeral 5 denotes a rack disposed on both sides of the frame 4 on the back side of the backrest 11 of the chair 3, and the rack 5 is formed over substantially the entire length of the backrest 11 of the frame 4 in the vertical direction.

Reference numeral 15 denotes a drive section installed on the back side of the backrest portion 11 over both the racks 5, 5 so as to be movable in the vertical direction of the rack 5. This drive section 15 includes a pinion 6 that meshes with the rack 5;
It is composed of a drive shaft 2, a kneading wheel 1, a clutch 16, a motor 8, etc.

That is, the pinion 6 is fixed to both ends of the moving drive shaft 7, and the drive shaft 2 is provided on the coaxial outer periphery of the moving drive shaft 7 so as to freely rotate over substantially the entire length of the moving drive shaft.

A pair of kneading wheels 1, 1 which are eccentric in the same direction and tilted toward each other are attached to substantially the center shaft of the drive shaft 2.

The drive shaft 2 and the moving drive shaft 7 are connected to a clutch 16 made up of a deceleration mechanism, a solenoid, etc., and the clutch 16 is connected via a belt 18 to a motor 8 which can be rotated in forward and reverse directions.

19 is used to turn on/off the power supply and connect the drive shaft 2 via the clutch 16.
This is a switch unit that drives the drive shaft 7 for movement.

Reference numeral 20 designates a roller guide rail attached to the moving drive shaft 7, which also serves as a protective cover for the rack 5 and pinion 6.

Further, a tension adjusting device for the kneading wheel cover 10 is provided between the pair of kneading wheels 1, 1, and as this tension adjusting device, a fastener 35 is formed in the vertical direction at the center of the kneading wheel cover 10 to adjust the tension of the kneading wheel cover 10. There are two stages.

Thus, the kneading wheel 1 is rotated by the rotation of the drive shaft 2,
Since the kneading wheel 1 is eccentric, the kneading action by pushing and tilting is performed via the kneading wheel cover 10 due to the change in the amount of protrusion due to its rotation.

The pinion 6 moves on the rack 5 by the rotation of the moving drive shaft 7, and the drive unit 15 is moved.

Therefore, the kneading wheel 1 moves up and down on the back surface of the backrest portion 1, resulting in so-called rolling massage.

At this time, even if the drive shaft 2 does not rotate and the amount of protrusion of the kneading wheel 1 is fixed, the rolling pine surge may be performed while the drive shaft 2 is rotated and the kneading wheel 1 performs a pushing operation.

In the kneading operation and rolling pine surge, the kneading condition of the kneading wheel 1 is adjusted as follows.

That is, the zipper 35, which serves as a tension adjustment device, is closed or opened, but as shown in FIG. As shown in FIGS. 1 and 3, when the length between the teeth on both sides of the zipper 35 is shortened, the tension of the kneading wheel cover 10 becomes stronger, and the kneading condition can be adjusted to two levels of strength and weakness while adjusting the degree of sinking of the body. Furthermore, by closing the zipper 35 and increasing the tension of the massage wheel cover 10, the chair does not get stuck in the body and does not cause any pain, so it can be used as an easy chair.

It is also possible to increase the number of fasteners 35 so that the tension of the wheel cover 10 can be varied in three or four stages.

Note that 36 is a rear cover. As described above, the present invention is equipped with a tension adjustment device for the massage ring cover in the pine massage device, so that treatment can be performed with the desired pine surgery strength using the massage wheel depending on the degree of tension of the massage wheel cover. This is particularly convenient when the treated area of the body is in pain because it can reduce the amount of kneading, and by tightening the kneading ring cover tightly, the built-in kneading ring no longer comes into contact with the body, making it easier to massage the body in a chair-shaped manner as in the illustrated embodiment. In some cases, it can be used as an easy chair.

In addition, since a tension adjustment device is installed between the pair of kneading wheels, it is possible to create slack in the kneading wheel cover between the kneading wheels to weaken the tension, or eliminate the slack to increase tension (stronger tension). In order to make this adjustment, the kneading wheel cover is applied almost equally to both kneading wheels, and the kneading wheel cover is not in contact with only one kneading wheel, so the adjustment can be made smoothly. Moreover, since the tension adjustment device is provided between the pair of kneading wheels, it is possible to adjust the tension of the entire cover without biasing it to one side.
