That is, the belt 5 shown in FIG. 2 is inserted through the rail 2, and this belt 5 is folded at one end of the rail 2 located at the other longitudinal end of the base 1. Both ends are guided to the driving device 4.

Although not shown, the drive unit 4 has a pair of drums around which one end and the other end of the belt 5 are respectively wound, and these drums are driven to rotate in opposite directions. ing.

As a result, one end of the belt 5 is wound around one drum and the other end of the belt 5 is unwound from the other drum, so that the portion inserted into the rail 2 runs in a predetermined direction. Driven. The massage unit 3 is connected to the belt 5 as described later, and is linked to the running of the belt 5.

As shown in FIG. 1, the massage unit 3 includes a pair of holding members 11 which are separated from the pair of rails 2 at substantially the same intervals. The holding body 11 has a substantially semicircular side shape, and both ends in the width direction along the longitudinal direction of the rail 2 are connected by a pair of lower connection shafts 12. A portion above the shaft 12 in the height direction is connected by an upper connecting shaft 13.

Lower connecting shaft 1 connecting a pair of holding bodies 11
Wheels 1 that roll on the upper surface of the rail 2
4 is rotatably mounted. That is, the lower connecting shaft 12 serves both to connect the pair of holders 11 and to attach the wheels 14. As shown in FIG. 2, both ends of a wire 15 are fixed to the outer surface of the holding body 11, and two midway portions of the wire 15 are connected to the belt 5. Thereby, as described above, the massage unit 3 can be linked with the running of the belt 5.

A pair of rocking members 16 which are spaced apart at a predetermined interval are supported at the middle of the upper connecting shaft 13 so as to be swingable. As shown in FIG. 3, the swing member 16 is formed in a bent portion 17 having both ends bent downward.
When the swinging member 16 swings by a predetermined angle, the lower connecting shaft 1 is located at the lower end of the bent portion 17 in the swinging direction.
Recess 1 as a contact portion for contacting and restricting the swing of contact 2
8 are formed.

A first mounting shaft 19 is provided on one end side of the pair of swinging members 16, and the mounting shaft 19 is provided with a plurality of protrusions 21a at predetermined intervals in the circumferential direction of the outer peripheral surface. A pair of first masses made of a material such as resin
A roller 21 is provided rotatably. The swing member 16
An auxiliary roller 23 made of a material such as rubber or synthetic resin by a second mounting shaft 22 is provided on the outer surface on the other end side of the
Are provided rotatably.

A vibration unit 24 is provided in the middle of the upper connecting shaft 13, that is, between the pair of swing members 16. The vibration unit 24 has a cover 25. As shown in FIG. 4, the cover body 25 has a substantially T-shaped planar shape formed by a storage portion 25a and a support portion 25b each having an open lower surface. The cover body 25 positions the storage portion 25a on the other end side of the swinging member 16 and on the side opposite to the first mass roller 21, and the end portion of the support portion 25b has the upper portion. It is swingably attached to the connecting shaft 13.

A torsion coil spring 26 is mounted on the upper connecting shaft 13 as an elastic holding member. Both ends of the torsion coil spring 26 are supported by the support portions 25 of the cover body 25.
The middle part is engaged with one lower connecting shaft 12 located on the support part 25b side.

Thus, the torsion coil spring 26
In FIG. 6A, the cover member 25 is swung at a swing angle, that is, the swing member 16 does not swing in the left-right direction.
The upper surface of the body 25 is elastically held in a state where it is slightly lower than the upper surface of the auxiliary roller 23 (the portion located at the upper end of the outer peripheral surface).

The storage section 25a has a semicircular cross section, in which an oscillator 31 is held. This oscillator 31 has a two-axis motor 32 as shown in FIGS.
A weight 34 is eccentrically mounted on the rotary shaft 33 of the rotary shaft 33, and a cylindrical body 35 integrally provided on the outer peripheral surface of the biaxial motor 32 is connected to the housing portion 25a by an elastic connecting member 36 such as rubber. It is elastically connected.

Therefore, the oscillator 31 has its two-axis mode
When the vibrator 32 operates and vibrates, the vibration is transmitted to the cover body 25 via the elastic connecting member 36. Therefore, the cover body 25 is attached to the support portion 25b while elastically deforming the torsion coil spring 26. With the upper connecting shaft 13 as a fulcrum, the storage portion 25a vibrates while swinging vertically.

At both ends of the upper connecting shaft 13, a pair of second masses made of a material such as rubber or synthetic resin having a plurality of projections 37a projecting from the outer peripheral surface at predetermined intervals in the circumferential direction.
A roller 37 is rotatably provided. In this second massaging roller 37, the swinging member 16 is formed as shown in FIG.
2B, the upper end is almost the same height as the first mass roller 21 when the concave portion 18 in the swing direction abuts on the lower connecting shaft 12 in the direction indicated by the arrow A in FIG. The external dimensions are set so that

As shown in FIG. 5B, the upper surface of the base 1 is covered with a cloth outer cover 38 so as to cover a massage unit 24 provided on the rail 2 so as to be freely movable. Coated.

According to the massage device having the above structure, the oscillator 31 is operated to reciprocate the massage unit 3 along the rail 2 in a state where the user lies upward on the exterior cover 38. When driven, the first massiller 21,
The second mass roller 37 and the auxiliary roller 23 rotate while contacting the back of the user via the outer cover 38. Therefore, the back surface of the user is massaged by the massagers 21 and 37.

When the oscillator 31 operates and vibrates,
The vibration is transmitted to the cover body 25, and the cover body 25
Also vibrate. That is, the cover body 25 is connected to the upper connecting shaft 13.
Vibrates while swinging up and down with the end of the support portion 25b connected to the fulcrum as a fulcrum. Therefore, the storage portion 25a of the cover body 25 applies vibration to the back of the user, and the vibration also causes the back of the user to be massaged.

An auxiliary roller 23 is rotatably provided on both sides of the cover body 25, that is, on the outer surface on the other end side of the swing member 16. The swing member 16 has a concave portion 18 at the lower end of a bent portion 17 formed at both ends to abut on the lower connecting shaft 12 and regulate the swing thereof.

Therefore, even if the swinging member 16 swings counterclockwise as indicated by arrow B in FIG. 6C, the uppermost end of the outer peripheral surface of the auxiliary roller 23 is higher than the upper surface of the cover body 25. Most of the user's load will not be reduced,
It is hardly excessively applied to the cover body 25 by being received by the cover 23.

If the load of the user is not excessively applied to the cover body 25, the cover body 25 is reliably vibrated at a large amplitude with the upper connecting shaft 13 as a fulcrum by the operation of the two-axis motor 32. Since a strong vibration can be given to the user, the massage effect by the vibration can be enhanced.

Further, the cover body 25 is elastically held on the upper connecting shaft 13 by a torsion coil spring 26.
Therefore, at the time of vibration, the resilient force of the torsion coil spring 26 acts on the cover body 25 to reinforce the vibration of the cover body 25, which can effectively provide the user with vibration.

In the vibration unit 24, the two-axis motor 32 of the oscillator 31 is covered by an elastic connecting member 36.
It is elastically attached to. Therefore, a part of the user's body falls between the pair of auxiliary rollers 11 and the cover 2
Even if a user's load is applied to 5, the oscillator 31 vibrates while elastically deforming the elastic connecting member 36.

As a result, the oscillator 3 is changed according to the load of the user.
Since the vibrations of the vibration unit 24 are prevented, the user can be surely massaged.

The swinging member 16 has a recess 19 formed at the lower end of each end of the swinging member 16 abutting on the lower connecting shaft 12 to limit the swinging angle in the left-right direction. As a result, the swing member 16 swings too much in the clockwise direction indicated by the arrow A in FIG. 6B, and the upper surface of the cover body 25 becomes lower than the upper end of the outer peripheral surface of the auxiliary roller 23. The vibration of the cover body 25 does not stop being transmitted to the user.

Conversely, the swinging member 16 swings too much in the counterclockwise direction indicated by the arrow B in FIG.
Is located below the upper surface of the cover body 25, and the load of the user is greatly applied to the cover body 25.
It is also possible to prevent the body 25 from hardly vibrating.

That is, by restricting the swing angle of the swing member 16 in the left-right direction, the cover body 25 is reliably vibrated,
Since the vibration can be transmitted to the user, the massage effect due to the vibration can be enhanced.

The swing member 16 provided with the first mass roller 21 and the auxiliary roller 23 swings about the upper connecting shaft 13 as a fulcrum. In other words, when the massage unit 3 travels along the back of the user, the massage unit 3 swings according to the uneven shape along the running direction of the back. Therefore, the first massaging roller 21 provided on the swing member 16 surely comes into contact with the back surface of the user, so that the massaging effect of the first massaging roller 21 can be enhanced. Can be.

It should be noted that the present invention is not limited to the above-described embodiment. For example, it is not necessary to provide the second mass rollers at both ends of the upper connecting shaft. Further, the means for driving the massage unit is not limited to the belt type described above, and other driving methods such as using a wire or a feed screw may be used. Further, the massage device of the present invention can also be applied to a chair-type massage device.

[0042]

According to the first aspect of the present invention, the vibration unit is elastically swingably held on the upper connecting shaft,
A swing member is provided on the upper connecting shaft so as to swing within a predetermined range, and an excessive load applied to the vibration unit by an auxiliary roller provided on the swing member is limited.

Therefore, since the load is not excessively applied to the vibration unit, it is not difficult to be elastically displaced, so that the massage effect due to the vibration of the vibration unit is prevented from being reduced.

According to the second aspect of the present invention, the vibration unit includes a cover provided on the upper connecting shaft so as to be elastically swingable.
And an oscillator provided elastically displaceable within the body.

Therefore, even if a load is applied to the cover body,
Since no load is applied directly to the oscillator, the oscillator is less likely to vibrate, and the massage effect due to the vibration is prevented from being reduced.
