BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cushioning body for use in, for example, a chair or a seat of a car, and more particularly to a cushioning body for massage having a plurality of electric vibrators therein.

[0002]

2. Description of the Related Art Conventionally, as a massage cushion body having a plurality of built-in electric vibrators, it is practically fair.
There are known ones that are used along with the seat of a car as in Japanese Patent Publication No. 46759, and ones in which a cushion body itself is a chair as in Japanese Patent Laid-Open No. 7-222781.

Although such a structure has a simple structure,
It is possible to easily massage the affected area by vibrating a vibrator that hits a more elaborate position on the body among the plurality of vibrators or by vibrating the entire vibrator.

However, as an electric vibrator,
There are those that generate vibration with an eccentric weight attached to the output shaft of the motor, those that generate vibration with an audio signal source generated from audio equipment, and those that generate vibration by vibrating the diaphragm with a solenoid. It is known, and therefore, with such a cushioning body for massage using an electric vibrator, so-called hitting massage that gives a shock to a stiff affected area cannot be performed.

As a device having a hitting massage function, there is generally known a system in which a pair of arms having a treatment element at the tip thereof are vertically rocked like a human arm. Had a complicated structure and was expensive.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described with reference to the drawings by taking an example in which a cushion body for massage is used along a chair or the like.

First, the structure of the massage cushion body 1 will be described with reference to FIGS. As shown in FIG. 4, the cushion body 1 is composed of a front cushion member 2 and a back cushion member 3. Both cushion members 2 and 3 are made of a cushion material such as soft polyurethane foam. An elastic polyester is integrally molded on the surface of the front cushion member 2 to form a skin 22 (see FIGS. 6 and 7).
See). 2 to 4, the front cushion member 2 receives the neck, both shoulders, the back, the waist, the buttocks, and the thighs of the human body. The cushioning is increased.

The outer surface of the back cushion member 3 is covered with a back cloth 4 made of cotton cloth. Then, the peripheral edges of the front and back cushion members 2 and 3 and the back cloth 4 are gathered together with a cotton tape 5 and sewn together to form the cushion body 1. As shown in FIG. 5, the backing material 4 is divided into two pieces, which are joined to each other by the fasteners 6. This is to make it easier to inspect the inside, as described later.

A plurality of electric vibrators 7 to 11 are built in between the cushion members 2 and 3. That is, as shown in FIG. 1, vibrators 7 to 11 are built in at positions where the neck of the human body, both left and right shoulders, waist, and thighs hit, respectively.

The vibrators 7 to 11 are motors, respectively.
This is a type in which an eccentric weight 18 is fixed to 12 to 16 output shafts 17. For details, as shown in FIGS. 6 and 7, an eccentric weight
Each of the vibrators 7 to 11 is constructed by attaching DC motors 12 to 16 having 18 to a metal mounting plate 20 via a bracket 19 made of ABS resin with screws 21.

Around each of the vibrators 7 to 11,
An intermediate cushion body 23 is arranged. The intermediate cushion body 23 is also made of a cushion material such as soft polyurethane foam. The vibrators 7 to 11 and the intermediate cushion body 23 are sandwiched between the front and back cushion members 2 and 3 and fixed at a predetermined position.

Here, a method of assembling the cushion body 1 will be described. The mounting plate 20 of each vibrator is fixed to a predetermined position of the front cushion member 2 by the adhesive applied to the mounting plate 20. Then, an intermediate cushion body 23 is arranged around the vibrators 7 to 11. An adhesive is applied to the entire inner surface of the back cushion member 3, and the vibrators 7 to 11 and the intermediate cushion body 23 arranged at predetermined positions are covered with the back cushion member 3, and the back cushion member 3 is covered. The vibrators 7 to 11 and the intermediate cushion body 23 are bonded. By doing so, the vibrators 7 to 11 and the intermediate cushion body 23 are simultaneously
It can be sandwiched between the front and back cushion members 2 and 3 and fixed at a predetermined position.

Thereafter, as described above, the back cushion member 3
The outer surface of 1 is covered with a back cloth 4, and the front and back cushion members 2 and 3 and the peripheral edges of the back cloth 4 are sewn together with a cotton tape 5 to complete the assembly of the cushion body 1.

In FIG. 4, reference numeral 24 is a wiring cord from the vibrator 7, which is a flexible tube so as not to be broken due to being twisted.
Passed through 25. The wiring cords from the other vibrators 8 to 11 are also the same, and as shown in FIG.
These wiring cords 24 are gathered in one place by a connector 26, and are connected to an operation unit 28 and a power supply connection unit 29 via a joint 27 attached to the peripheral edge of the cushion body 1.
The power supply connection portion 29 is connected to a cigarette lighter plug of a car or a household power supply adapter.

The tube 25 is also fixed to a predetermined position at the same time with the adhesive applied to the back cushion member 3 when the vibrators 7 to 11 and the intermediate cushion body 23 are covered with the back cushion member 3. It

By the way, a notch 30 is partially provided at a position surrounding the intermediate cushion body 23 of the back side cushion member 3. This is to facilitate maintenance and inspection of the vibrators 7 to 11.

For maintenance and inspection, the fastener 6 of the back cloth 4 is opened, and the back cloth 4 is moved toward the front cushion member 2 as shown by the dotted line in FIG.
Appears in front of me. Then, cut the back cushion member 3 at the notch 30 and pull it, as shown in the figure.
The vibrator 8 easily appears with the intermediate cushion body 23 attached to the back cushion member 3. This is because the intermediate cushion body 23 and the front cushion member 2 are not adhered to each other, and only the rear cushion member 3 and the vibrator bracket 19 are in contact with each other in a small area. This is because it only needs to be peeled off.

Next, the electric circuit and the operation will be described with reference to FIGS.
It will be described based on. FIG. 10 is a circuit configuration diagram, and FIG. 12 is an operation unit.
28 is a front view of FIG. The power source is a car cigarette lighter plug or a household power adapter that converts household power into direct current.
Connected to. Reference numeral 31 is a power switch, 32 is a constant voltage circuit such as a constant voltage IC, 33 is a control circuit such as a micro computer, 34 is a display circuit, and the user can tell which vibrator 7 to 11 is vibrating. LEDs 35 to 39 that are lit to show the user's understanding, and L that is lit to show the user whether the course is a full-body course or a shoulder tap course, which will be described later.
It consists of ED40, Nobi 41 and so on.

Reference numeral 42 denotes an input circuit, which includes various operation switches from the operation unit 28. In addition to the power switch 31, the operation unit 28 includes a selection switch A43 for selecting a whole body course or a shoulder tapping course, a selection switch B44 for selecting a vibrator to vibrate, and a selection switch C45 for selecting continuous operation or intermittent operation. Have. Further, 46 to 50 having the LEDs 35 to 41 in the operation portion are motor drive circuits of the respective motors 12 to 16 and are driven by a signal from the control circuit 33.

Next, the operation will be described. This massage cushion body 1 is used along with a chair as shown in FIG.

First, description will be made on a case where automatic driving is performed for either the whole body course or the shoulder tapping course. When the power switch 31 is turned on and the selection switch A43 is pressed, the signal is output to the control circuit 33.
Then, the control circuit 33 determines that there is a command for the whole body course, and turns on the LED 40 next to the display of "whole body" on the operation unit 28. Then, an operation signal is output to the motor drive circuit 46 to operate it, and the motor 12 at the position of the neck is driven. At the same time, the LED 35 of the operation unit corresponding to the position of the neck is turned on. As a result, the vibrator 7 vibrates and massages the neck muscle.

After a lapse of a predetermined time, for example, 5 seconds, the control circuit 33 outputs a stop signal to the motor drive circuit 46 to stop the operation, and instead outputs an operation signal to the motor drive circuit 47 to operate the motor drive circuit 47, and the right shoulder Drive the motor 13 in the position.
At the same time, the LED 37 of the operation unit corresponding to the position of the right shoulder is turned on. As a result, the vibrator 8 vibrates and massages the right shoulder.

After a further 5 seconds, the motor drive circuit 47 is stopped in the same manner and the motor drive circuit 48 is driven to drive the motor 14 at the left shoulder position. At the same time, the LED 36 of the operation unit corresponding to the position of the left shoulder is turned on. As a result, the vibrator 9 vibrates and massages the left shoulder.

After a further 5 seconds, the motor 15 at the waist position is driven at this time, and at the same time, L corresponding to the waist position is reached.
Turn on ED38. As a result, the vibrator 10 vibrates and massages the waist.

After a further 5 seconds, the motor 16 at the thigh position is driven this time, and at the same time, the LED 39 corresponding to the thigh position is turned on. As a result, the vibrator 11 vibrates and massages the thigh.

After a further 5 seconds, the motor 12 at the neck position is driven again to massage the neck muscles. Thereafter, this operation is repeated. That is, the neck, right shoulder, left shoulder, waist and thighs are automatically massaged every 5 seconds. This is the case when the whole body course is set.

Next, when the selection switch A43 is pressed again, the signal is input to the control circuit 33, and the control circuit 33 judges that the command is for the shoulder tapping course, and the "both shoulders" of the operating section 28 is judged.
The LED 41 next to the display is turned on.

In this shoulder tapping course, the motor drive circuit 47
And the motor drive circuit 48 are alternately driven at relatively short intervals such as a shoulder tap. Specifically, as shown in FIG. 11, the operation of driving the motor drive circuit 47 for 0.2 seconds, stopping for 0.3 seconds, driving the motor drive circuit 48 for 0.2 seconds, and stopping for 0.3 seconds is repeated. That is, the motors 13 and 14 located on the left and right shoulders are alternately driven to vibrate the vibrators 8 and 9 alternately. At the same time, the LEDs 36 and 37 are alternately turned on.

As a result, the vibrators 8 and 9 located at the left and right shoulders alternately vibrate for 0.2 seconds and stop for 0.3 seconds. The interval of this repetition is similar to the rhythm of hitting the shoulder, and as a result, the vibrations of the vibrators 8 and 9 are transmitted to both shoulders as if they were a hit massage. This is the operation of the shoulder tapping course.

Each time the selection switch A43 is pressed, the whole body course is switched to the shoulder tapping course, and the shoulder tapping course is switched to the whole body course.

The selection switch B44 is for manual operation. Each time it is pressed, the driving motors 12 to 16 are changed,
The massage is performed by selecting only the affected area that is stiff. That is, each time it is pressed, the vibrators 7 to 11 at the positions of neck, right shoulder, left shoulder, waist and thigh are vibrated, and at the same time, the LEDs 35 to 39 corresponding to the respective positions of the operation unit 28 are turned on.

When the desired switch is massaged by pressing the selection switch B44, if the selection switch C45 is pressed, the driving motors 12 to 16 are intermittently driven.
Specifically, it is driven intermittently, such as driving for 1 second and stopping for 0.5 seconds. Then, intermittent vibration is applied to the affected area. When the selection switch C45 is further pressed, the continuous drive is resumed. That is, each time the button is pressed, continuous operation or intermittent operation is switched.

The automatic driving, which is the whole body course and the shoulder tapping course, and the manual driving, which have been described above, are automatically terminated by a timer when they continue for 15 minutes in consideration of the influence on the human body.

In the above embodiment, the selection switch A43 is used to obtain the same stimulus as hitting massage on both left and right shoulders. However, for example, vibrators are built in the left and right waist positions and this vibrator is used. As in the case of the shoulder tapping course, by alternately vibrating, the same massage as tapping can be performed on the waist, and the tapping massage is not limited to both shoulders.

To obtain a hit massage, the pair of left and right vibrators 8 and 9 are alternately vibrated at a constant rhythm of 0.2 second vibration and 0.3 second stop, but this rhythm is not constant but slowed down. If you speed it up, you can get a variety of tapping massages.

Further, the rotation speed of the motors 12 to 16 can be made variable so that the intensity of vibration can be adjusted.

[0042]

According to the present invention (the invention of claim 1), the pair of left and right vibrators among the electric vibrators are
Since there is a beating course (shoulder beating course in the embodiment) in which the left and right are alternately vibrated at relatively short intervals like a shoulder beating, by driving this course, the vibration causes the beating massage to be performed. Such a shock is transmitted to the affected area, and even a massage cushion body having a simple structure in which a plurality of electric vibrators are incorporated can perform the same massage as the hitting massage.

Further, as in the second aspect of the present invention, by setting the relatively short interval to a constant interval, it is possible to perform hitting massage with a constant rhythm.

Further, as in the invention of claim 3, if the pair of left and right vibrators are incorporated at positions where both shoulders of a human body hit, the shoulders that are most prone to stiffening are struck. A similar massage can be done.
