DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chair-type electric massage device, and more particularly to a chair-type electric massage device in which a user's labor is reduced.

[0002]

2. Description of the Related Art A conventional chair-type electric massage device incorporates an electric massage mechanism in a back portion of a manual reclining seat. The electric massage mechanism is "Mom"
An operation mode such as "tapping" can be selected, and the operation mode is switched mechanically, or an operation mode is automatically selected by a microcomputer or a series of massage programs are automatically performed.

[0003]

The massage effect of the chair-type electric massage device differs significantly depending on the angle of the backrest. That is, in the state close to vertical, the load on the human body applied to the backrest is small, so that the massage effect is weak. Therefore, it is necessary for the user to adjust the reclining angle so as to obtain a desired strength. However, the user usually uses the reclining angle almost horizontally. Therefore, after the massage is completed, the upper body must be raised and the backrest must be raised by manual operation, which requires labor and is not sufficiently operable.

[0004] Therefore, there arises a technical problem to be solved in order to improve the operability, reduce the labor and improve the medical effect, and an object of the present invention is to solve the problem. .

[0005]

SUMMARY OF THE INVENTION The present invention has been proposed in order to achieve the above-mentioned object , and has a built- in electric massage mechanism comprising a motor, a cam, a lever and the like in a back portion of a chair , and Chair-type electric massage device configured to interlock the operation of the electric reclining mechanism of the backrest with the operation of the electric massage mechanism
In the electric massage device, the automatic massage device
Is the backrest upright with the start of the program?
To start the massage by tilting it horizontally.
At the end of the massage program, the backrest
An object of the present invention is to provide a chair-type electric massage device including a control unit that ends a massage by standing up from a horizontal state .

[0006]

The electric reclining mechanism built in the chair-type electric massage device is linked by the control unit of the electric massage mechanism. When the user sits on the device and turns on the massage selection switch, the backrest is standing
Then, the massage starts by tilting horizontally . Also, if turning off the switch to exit the massaging operation, to end the massaging operation backrest portion is erected from the horizontal state
You.

An embodiment of the present invention will be described below in detail. still,
For convenience of explanation, technical matters belonging to the related art will be described at the same time. FIG. 1 shows a chair-type electric massage device 1 in which a backrest 2 is configured to be able to stand up and down between an upright position shown by a solid line and a horizontal position shown by a chain line. The reclining of the backrest 2 is performed by a known electric reclining mechanism 3 using a motor. 4 is the backrest 2
"Rolling" which is an electric massage mechanism built in the machine that moves the rollers 5, 5 up and down along both sides of the spine
Then, massages such as "acupressure" and "slap" for moving the rollers 5, 5 back and forth by a cam (not shown) can be performed. The operation of the massage and the reclining is performed by the operation panel 7 provided on the upper surface of the armrest 6. The operation panel 7 is provided with a power switch, a massage selection switch, a reclining operation switch, and the like, which will be described later.

FIG. 2 is a circuit block diagram of the chair-type electric massage device 1, 11 is an electric massage circuit, 12 is an electric reclining circuit, and 13 is a CPU. Reference numeral 14 of the operation panel 7 is a power switch, reference numerals 15, 16, and 17 are selection switches for an automatic massage program, and reference numerals 18 and thereafter are manual selection switches.
9 is a "hit" switch. Reference numerals 20 and 21 denote switches for setting the upper and lower positions of the rollers 5 and 5, and reference numerals 22 and 23 denote switches for adjusting the amount of protrusion of the rollers 5 and 5 from the spine during rolling to set the strength of the massage effect. Reference numerals 24, 25 and 26 denote switches for setting the vertical movement range of the rollers 5 and 5 in the "rolling", respectively.
"Shoulder" 24 and "Whole body" 25 and "Waist" 26 from shoulder to waist
And can be selected. Reference numerals 27 and 28 denote reclining operation switches, and the backrest 2 tilts in the direction indicated by the switches 27 and 28 while the switches 27 and 28 are kept pressed.

The switches 14 to 28 are connected to the CPU 13 through an I / O port 29,
Controls the motor driving circuits 31, 32, 33 of the electric massage circuit 11 or the electric reclining circuit 12 from the data of the ROM 30 according to the input contents,
35 and 36 are driven. In addition, the electric reclining circuit 1
Reference numeral 37 in 2 denotes a relay circuit for reversing the DC motor 36, and 38 denotes a relay drive circuit.

The reclining program associated with the massage program is input to the ROM 30 in advance. Turn on the power switch 14 and press the "Shiatsu" switch 1
8, "striking" switch 19, rolling "strong"
When one of the "weak" switches 22 and 23 is turned on, the backrest 2 is reclined to a predetermined angle, and when the power switch 14 is turned off, the massage operation is stopped, and after the backrest 2 is erected, the power is turned off. It is configured. Also, the reclining angle is changed by specifying "strong" or "weak" of the rolling by the switches 22 and 23,
In the case of "strong", it may be configured to perform full reclining to enhance the massage effect.

In the automatic program, the massage part can be selected from the shoulder, the whole body, and the waist, and the moving range of the rollers 5 and 5 is designated respectively. Here, a program when “whole body” is selected will be described as an example. First, as shown in FIG. 3, with the start A of the program, the backrest portion 2 in the standing position is tilted to about 45 degrees, and at the same time, the rollers 5, 5 make one reciprocation in the "rolling" from the shoulder to the waist in a weak state. . Next, descend to the waist while performing “Shiatsu” S, and “rolling”
To rise. Subsequently, the lowering of the "acupressure" S and the raising of the "rolling" are repeated again, and the backrest 2 is fully reclined (B), the lowering by the "hitting" F, the rising of the "rolling", and further the "hitting" F After lowering, the backrest 2 is raised to approximately 45 degrees (C). Then, after going up, down, and rising by "rolling", the backrest 2 is erected (D), and the "whole body" automatic massage program is ended.

As described above, by linking the massage function and the reclining function, the user's burden of standing up can be reduced by automatic reclining during manual setting.
When an automatic program is selected, the massage effect can be further improved. Note that the present invention is not limited to the above-described embodiment, and various modifications can be made to the automatic massage program, switch settings, and the like, and the present invention naturally extends to those modifications.

[0014]

As described in detail in the above embodiment, the present invention is provided in a chair-type electric massage device.
The operation of the electric reclining mechanism that, built into the backrest
In conjunction with the operation of the electric massage mechanism
When executing the operation of the electric massage device, the control unit
With the start of the automatic massage program, the backrest
Tilt horizontally from the standing position to start massage
With the end of the automatic massage program
Then, the backrest is raised from a horizontal state and massaged.
Since to terminate, it is possible to reduce the effort of the user of the reclining angle adjustment at the beginning and end of the massage, further Hakare improvement of massaging effect in the automatic massage program, resulting in a significant effect in improving the functionality and usability It is an invention.
