Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to a pine massage machine having a movable kneading ring provided on the back support frame of a chair, bed, or the like.

BACKGROUND TECHNOLOGY Conventionally, as a pine surge machine, for example,
No. 194 and Japanese Unexamined Patent Publication No. 49-51786, all of these pine surge machines have a sheet placed on the top of the kneading wheel, so when the seat tension is applied, the sheet gets in the way and prevents the massaging. This makes it difficult for the rings to come into contact with the body, making it impossible to perform effective pine surgery.

Another problem is that when the seat is loosened, the body sinks too deeply (this tendency is particularly strong in seats with a pair of massage wheels).

OBJECTS OF THE INVENTION The present invention was invented in view of the above points, and its purpose is to provide a pine surgery machine that prevents the body from sinking too deeply and allows effective pine surgery.

DISCLOSURE OF THE INVENTION The pine surge machine of the present invention includes a movable kneading ring 4 provided in a substantially rectangular back support frame 1, and a plurality of belt-shaped body supports stretched in the moving direction of the kneading ring. The kneading ring 4 is made to be able to protrude freely between a plurality of belt-shaped body support bodies, and with such a configuration, the above-mentioned object of the present invention is achieved.

The present invention will be explained in detail below with reference to Examples.

In FIG. 1, 1 is a back support frame in which a pipe is framed in a substantially rectangular shape, 6 is a seat pipe, and 7 is a leg pipe.

It is an 8-height body support body that is composed of two side belts 9 and one center belt 10.

The outer edge of each side belt 9 is connected to each vertical portion 11 of the back support frame 1 by a connector 12.

Here, the connector 12 is connected to the vertical portion 11 of the back support frame 1 as shown in FIG.
A fixed piece 13 welded to the fixed piece 13 and a washer 1 fixed to this with a screw 14
5, and the sight belt 8 is connected to the washer 15 with an eyelet 16.

The upper end of each side belt 9 is attached to a back support frame 1 as shown in FIG.
is fixed to the upper lateral part 17 of the
The lower end is connected to the lower lateral portion 19 of the back support frame 1 via a tension spring 20.

As shown in FIG. 3, the upper end of the sensor belt 10 is fixed at the right middle part of the back support frame 1 with a fixing tool 18 similar to the side belt 9 on the upper lateral part 17 of the back support frame 1, and the lower end is It is connected to the lower end of the wheel cover 2 by a tension spring 3.

Here, each fixing device 18 for the side belt 9 and center belt 10 may be hook-shaped as shown in FIGS. 7 and 8.

As shown in FIG. 1, the kneading wheel cover 2 covers the back support frame 1 in front of the belt-shaped body support 8, and its both side edges connect each side belt 9 to the vertical part 11 of the back support frame 1. Each fixing device 1 is connected to the back support frame 1 by sharing a connecting device 12, and its upper end fixes the side belt 9 and center belt 10 to the upper lateral portion 17 of the back support frame 1, as shown in FIG.
8 is shared and fixed.

As shown in FIG. 1, both sides of the lower end of the kneading wheel cover 2 are attached to the lower lateral part 19 with lower end hooks 21 that lock the tension spring 20 connected to the side belt 9 to the lower lateral part 19 of the back support frame 1. It is fixed at the same time as 20 is locked.

As shown in FIGS. 1 and 3, a connecting protrusion 22 extends from the center of the lower end of the kneading wheel cover 2 so as to wrap around the lower lateral part 19 of the back support frame 1. 22 is connected to the center belt 10 via the tension spring 3 as described above.

Reference numeral 4 denotes a pair of left and right massage wheels, which are arranged to eccentrically swing and rotate in a gap 23 provided between each side belt 9 and center belt 10.

When performing pine surgery using the above-mentioned pine surgery chair, the user presses his/her body against the backrest 5 as shown in Figure 3, moves the massaging wheel 4 up and down to a desired position, and performs eccentric rocking rotation.

When the body is pressed against the backrest 5, the massaging wheel cover 2 tries to deform along the curve of the body, and the tension spring 3 is stretched by this force, allowing the massaging wheel cover 2 to deform, and the massaging wheel cover 2 is moved at the required pine surge area. 2 does not tense up, and the pushing and grasping of the massaging wheel 4 can be surely transmitted to the body.

Further, when the pine-surge chair is not used, the tension spring 3 is compressed as shown in FIG. 3a, and the massage wheel cover 2 is maintained in a taut state to prevent sagging or wrinkles.

Here, in the belt-shaped body support body 8, when the user sits on the Matusage chair, the belts 9 and 10 are elastically deformed along the lines of the body, as shown in FIGS. 4 and 5. The body is pushed and pulled in accordance with the movement of the massaging wheel 4, so it deforms and stretches at the same time (
When the chair is not seated, that is, when it is not in use, the center belt 10 always remains in a straight state as shown in Figures 4a and 5a, and when viewed from the side. Sometimes it is pushed out further than the side belt 9, and its tension helps adjust the external shape of the kneading wheel cover 2.

Since the side belt 9 is fixed by the connector 12 along the curve of the vertical part 11 of the back support frame 1, only the inner edge deforms according to the movement of the body, and the outer edge does not deform. .

FIG. 6 shows another embodiment in which the center belt 10 and the grip ring cover 2 are separated from each other, and both are telescopically connected to the lower lateral portion 19 of the back support frame 1 by a tension spring 3.20.

In this embodiment as well, the expansion and contraction of the tension spring 3 allows the massage wheel cover 2 to sink deeply along the body, and also prevents sagging and wrinkles when not in use.

In both of the above embodiments, the lower end of the massage wheel cover 2 is connected to the lower lateral portion 19 of the back support frame 1 by the tension spring 3, but contrary to these, the upper end of the massage wheel cover is connected to the lower end of the backrest pipe. It may be connected to the upper lateral portion by a tension spring, or both the upper and lower ends may be connected to the backrest pipe via a tension spring.

As shown in FIG. 2, the belt-shaped body support 8 is constructed with a side belt 9 tapered on the inner edge side and a center belt 10 tapered on both side edges, and these belts 9 and 10 are For example, if you use a material made of a chemical product with high tensile strength such as polypropylene, it will have sufficient strength to support your body, and you will also feel the tips of the belts 9 and 10 touching your body when you sit on the Matusage chair. It can support the body with a soft feel, and unlike urethane foam, it does not have a large apparent cross-sectional area, and the massage wheel 4 can be placed close to the body, improving the massage effect. You will be able to do this.

By the way, the present invention is not limited to a chair type, but may also be a bed type.

Further, the kneading wheel 4 may be eccentrically inclined, eccentric only, or neither eccentric nor inclined.

Effects of the Invention In the present invention, as described above, a movable massaging ring is provided within a substantially rectangular back support frame, and a plurality of belt-shaped body supports are stretched in the direction of movement of the massaging wheel. Since the kneading ring is made to freely protrude between the plurality of belt-shaped body support bodies, the body is supported by the belt-shaped body support bodies and does not sink too deeply, and the kneading ring can be protruded between the plurality of belt-shaped body support bodies. Since the body support bodies are allowed to protrude freely between the body support bodies, the belt-like body support bodies do not get in the way, and effective pine surge can be performed.
