DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a massage machine mounted on a backrest such as a massage chair provided with an improved vertical massage.

[0002]

2. Description of the Related Art A massage machine mounted on a backrest of a massage chair or the like is used as a tapping massage in various directions, that is, in a horizontal direction, along a longitudinal direction of a backrest of a chair known as a stretching massage. It is known to be able to perform massages in the direction along the lateral direction of the known chair back and so-called kneading massages.

[0003] These types of massage are provided by rotating the appropriate shafts about their respective axes so as to produce alternating movements of the massage wheels in substantially horizontal and vertical directions.

Conventional massage devices therefore have a plurality of gear motors, one for each different operation of the massage wheel, which gear motors are connected to the massage wheel by their drive shaft and by a dedicated lever system. And therefore transmit the selected movement to the wheels.

While conventional massage devices are very effective in terms of the type of massage provided, they are complex to manufacture and can perform multiple massage operations on the massage wheel, thus requiring multiple gear motors. They are very expensive.

On the other hand, stretching massages, ie massages in which the massage wheel supported by the adapted carriage moves along the back of the user, are unsophisticated and inadequate for the user's massage requirements. .

While the stretching-type single massage solution offers significant cost savings, it does not provide sufficient massage quality, as described.

[0008]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a massage machine mounted on a backrest such as a massage chair, which can provide an improved vertical massage.

[0009] Within this aim, the object of the present invention is:
It is an object of the present invention to provide a massage machine which can be attached to a backrest such as a massage chair, in which a stretching massage is significantly improved at a low cost.

It is another object of the present invention to provide a massager mounted on a backrest, such as a massage chair, in which a stretching massage can be controlled with respect to its duration and the body area to be massaged.

Yet another object of the present invention is to provide a highly reliable, relatively easy to manufacture and competitively cost effective,
An object of the present invention is to provide a massage machine mounted on a backrest such as a massage chair.

[0012]

SUMMARY OF THE INVENTION This aim, these objects, and others which will become apparent hereinafter, comprise a threaded shaft on which a carriage can slide, said carriage supporting a plurality of massage wheels. And actuated along the threaded shaft by a gear motor to control the operation of the gear motor to switch the direction of rotation of the gear motor, and thus to switch the direction of movement of the carriage along the threaded shaft. The present invention is achieved by a massage machine mounted on a backrest such as a massage chair, which is provided with a control unit that performs the control.

Further features and advantages of the present invention will become apparent from the following detailed description of preferred but non-exclusive aspects of the device according to the invention, which is illustrated in conjunction with the drawings for purposes of non-limiting example only. There will be.

[0014]

Embodiments of the present invention will be described below with reference to FIG. As shown in FIG. 1, a massage machine according to the invention is designated by the reference numeral 1 and has a substantially vertical threaded shaft 2 which supports a movable frame or carriage 3 so that it can slide along the shaft. In a conventional manner, and the frame also supports the massage wheels 4 such that they can rotate about their respective axes.

More particularly, a threaded shaft 2 which can be fixed on request to a fitted chassis indicated by reference numeral 5 or can be mounted directly on a backrest of a massage chair or the like fixed to the support structure of the chair. Is rotated by a gear motor 6 intended to move the frame or carriage 3 vertically along the threaded shaft 2 to provide a stretching type massage.

The specificity of the present invention is that the massage of the type described above is performed statically, with the option of choosing only the entire back or lower region or only the central or upper region, that is, it can be chosen as desired. Is applied repeatedly to the same part of the back of the user, or is performed stepwise, ie, the massage carriage 3 moves upward or downward stepwise during the massage.

Control of the massage is provided in two ways: by movement of the carriage 3 having a preset required time; by movement of the carriage 3 having a preset stroke length.

The massage described above, which is, in effect, an alternating "rubbi" longitudinally with respect to the direction of movement of the carriage 3 along the threaded shaft 2.
ng) "is provided by the circuit shown in FIG.

The circuit shown in FIG. 1 comprises a motor drive means connected to the motor 6 and advantageously comprising a first relay 7 and a second relay 8 supplied with a supply voltage Vdd, for example. are doing. The motor 6 instead supplies the supply voltage V
Supplied with cc.

The relays 7 and 8 are provided with a motor 6 for reciprocating the carriage 3 along the threaded shaft 2.
Is adapted to control the direction of rotation.

[0021]

[Table 1]

In particular, as shown in the above table, A and B
Indicates the terminals of the relays 7 and 8, respectively, when both terminals A and B are not supplied with power (indicated by φ in Table 1), the carriage 3 does not move. In this case, the supply voltage Vcc of the motor is supplied to both poles of the motor to prevent its rotation. This situation also occurs when both terminals A and B are provided with the supply voltage Vdd.

Alternatively, when only one of the terminals A and B is supplied with the voltage Vdd, the carriage 3 moves up or down along the threaded shaft 2.

In FIG. 1, x indicates the moving direction of the carriage 3, x _MAX indicates the maximum stroke of the carriage 3, and φ indicates the minimum stroke of the carriage.

The first type of massage, that is, the massage in which the operation of the carriage 3 has a predetermined required time, is performed as follows. T1 relay 7
And T2 is the operation time of the relay 8,
If T1 = T2, a static massage is performed and T1> T
If 2, the stepwise massage is performed in one direction along the threaded shaft 2, and if T2> T1, the stepwise massage is performed in the opposite direction.

Alternatively, the type of massage provided by a predetermined length of movement of the carriage 3 is obtained, for example, by using a position detector such as an encoder 9 for the motor 6. This allows the carriage 3 to always be located at a selected position, equal to the pulse supplied from the encoder 9 when the massage is started, and pre-determined according to the length and type of massage to be provided. Set time, relays 7 and 8
Voltage can be applied to the

The massager described above therefore makes it possible to carry out a "rubbing" type massage by reciprocating the carriage along the threaded shaft 2.

The means for driving the motor 6 is therefore:
According to the type of massage intended, it is possible to change the direction of rotation of the motor 6 and therefore the direction of movement of the carriage 3 along the threaded shaft 2, and thus the stroke of the carriage 3 along the threaded shaft 2. It is possible to set both the required time and the length.

Indeed, the massage machine according to the present invention completely integrates a conventional stretching massage with a reduced cost compared to a massage machine which is provided with a more complex massage function and thus requires more gear motors. It is acknowledged that the intended aim is fully achieved as it is possible.

The device so represented is capable of numerous modifications and variations, all falling within the scope of the claims.
Furthermore, all the details may be replaced by other technically equivalent elements.

In practice, the materials used can be any according to requirements and state of the art, as well as dimensions, as long as they are suitable for the particular application.
