Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a chair type massage machine. More specifically, the present invention relates to a chair type massage machine that can accurately detect a body part of a user.
[0002]
[Prior art]
There is a chair-type massage machine (10) on which a user sits down and receives a shoulder, back, and waist massage from the neck.
As shown in FIGS. 2 and 3, the massage machine (10) is configured such that a massage unit (30) is disposed so as to be movable up and down on a backrest (13) of a chair (11) on which a user sits.
[0003]
The massage unit (30) has a pair of left and right treatment fingers (40) and (40) arranged so as to protrude from the backrest (13). The patient is massaged by operating it.
[0004]
In the massage machine (10) of the above mechanism, by moving the massage unit (30) up and down, a rolling massage is performed from the shoulder to the back and waist of the user, and the massage unit (30) is moved up and down at a desired site. Can be stopped and partial massage can be applied. In addition, it is possible to combine a massage massage or a partial massage with a massage or a hitting operation, or a programming massage combining these massage operations.
[0005]
When performing a rolling massage, the massage unit (30) is reciprocated in the range from the shoulder to the waist of the user. At this time, the shoulder position of the user to be the upper limit of movement of the massage unit (30) is detected. There is a need. This is because if the shoulder position is not detected correctly, the treatment finger cannot reach the desired site, or massage is performed on a site different from the desired site, and the massage effect may be reduced or uncomfortable.
However, the position of the shoulder is different for each user, and even the same user changes its position depending on how the user sits on the chair.
[0006]
Therefore, there is a massage machine provided with position detection means (70) for detecting the shoulder position. The position detection means (70) includes a sensor for detecting the angle change and pressure change of the treatment fingers (40) and (40), and the angle change and pressure change of the treatment finger caused by the treatment finger hitting the user are previously detected. Compared with the measured pattern, the shoulder position is detected. Japanese Patent Laid-Open No. 6-190012 (A61H7 / 00) is a massage machine that detects a shoulder position based on a pressure change.
In order to increase the detection accuracy of the shoulder position, it is necessary to strongly press the treatment fingers (40) and (40) against the body of the user. Therefore, when the shoulder position is detected, as shown in FIG. 11, the massage unit (30) is backrested (13) with the treatment fingers (40) (40) protruding forward from the backrest (13). It is moved from the top to the bottom.
[0007]
[Problems to be solved by the invention]
When the shoulder position is detected in a state where the treatment fingers (40) and (40) protrude forward of the backrest (13), as shown in FIG. 12 (a), the body of the user is treated with the treatment finger (40). It is pushed by (40) and moves forward.
In particular, in a massage machine that can change the angle of the backrest (13), if shoulder position detection is performed with the backrest (13) tilted, the treatment fingers (40) (40) pass through the shoulder and After detecting the position, the massage unit (30) further moves below the backrest (13). At this time, as shown in FIG. 12 (b), the treatment fingers (40) and (40) hit the waist, which is the center of gravity of the body, and the body is pushed forward as the massage unit (30) moves downward. Deviation occurs. Therefore, the position of the body of the user is different before and after the shoulder position detection, and the accuracy of the shoulder position detection is lowered. As a result, there is a problem that a desired massage cannot be received at a desired site. This phenomenon was more common in light weight people.
[0008]
An object of the present invention is to provide a chair type massage machine that can accurately detect a body part of a user.
[0009]
[Means for Solving the Problems]
In order to solve the above problems, the chair type massage machine of the present invention is
A massage chair with a backrest on the seat on which the user sits;
A treatment finger that protrudes forward from the backrest and massages the user, a squeezing means that moves the treatment finger back and forth, and a height relative to the backrest of the body part of the user that the treatment finger is in contact with A position detecting means for detecting the massage unit, and a massage unit that can be moved up and down in the backrest;
A lifting mechanism that lifts and lowers the massage unit along the backrest;
Control means for storing the height of the body part of the user detected by the position detection means and controlling the operation of the lifting mechanism and the squeezing means with reference to the stored height of the body part;
In a chair type massage machine comprising
When the control means detects the shoulder position of the body, the massage unit is located in a range from the upper end of the backrest to the lower side of the massage unit with the treatment finger protruding forward by the kneading means. Lowering the detection range narrower than the entire lifting range, the position detection means detects the shoulder position of the user, and after the massage unit is out of the detection range, the treatment finger is moved backward by the kneading means . Is.
[0010]
[Action and effect]
The body shoulder position is detected in a detection range narrower than the entire lifting range of the massage unit. For example, the detection range is a height in the vicinity of the middle of the backrest from the upper end of the backrest. In the detection range, the treatment finger protrudes forward in order to increase the detection accuracy of the shoulder position. Then, after the massage unit is out of the detection range, the treatment finger is moved backward.
Since the detection range is narrowed as described above and the treatment finger is protruded forward only in the detection range, the body of the user is not displaced before and after the detection by raising and lowering the massage unit. Therefore, the detection accuracy of the shoulder position of the user can be increased.
By correctly detecting the height of the shoulder position of the user, the desired part of the user can be massaged, and the massage effect is not reduced and uncomfortable feeling is not felt.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
The position detection means (70) is configured so that the treatment finger (40) (40) is in contact with which part of the body of the user or the height of the backrest (13) is the part of the body of the user. Means for detecting the presence can be used. As such a position detection means (70), the shoulder of the user is determined from the change in the angle or pressure of the treatment finger (40) (40) caused by the treatment finger (40) (40) coming into contact with the treatment person. There are those that detect only the position, and those that detect the position of the back and waist.
The mechanism and position detection method of the position detection means (70) are not particularly limited, and various mechanisms and methods can be used. Moreover, it does not specifically limit about the site | part to detect.
[0012]
The control means (100) is arranged at a proper position of the massage machine (10) and controls all of the massage machine (10). As shown in FIG. 1, the control means (100) can be composed mainly of a microcomputer (101). The microcomputer (101) includes a position detection means (70) and an operation remote controller (102) to be described later. Drive circuit (104) (105) (106) (107) of the motor (21) (51) (61) (91) that drives the input circuit (103), the massage unit (30) and the reclining mechanism (90) A motor detection circuit (108) for detecting the rotation of the motors (21) (51) (61) (91) is connected.
The microcomputer (101) includes a memory for storing the shoulder position detected by the position detection means (70).
[0013]
The height of the body part of the user is preferably detected by lowering and / or raising the massage unit (30) with the treatment fingers (40) and (40) protruding forward. The treatment fingers (40) and (40) can be made to protrude forward by driving a kneading means (50) described later and stopping at a predetermined position.
The detection range by the position detection means (70) is a range narrower than the entire elevation range. Specifically, when the shoulder position is detected as a body part, as shown in FIG. 9, the treatment finger (40) (40) is protruded from the upper end of the backrest (13) in the state where it is projected most forward. Lower the massage unit to the middle height of the backrest (13). When it is out of the detection range, the massage means (50) is driven to perform massage massage, the treatment fingers (40), (40) are lowered backward, and the massage unit (30) is moved up and down to perform rolling massage.
[0014]
The detected shoulder position is overwritten in the memory of the microcomputer (101), and a rolling massage or the like performed later is performed based on the changed shoulder position.
[0015]
The detection range is not limited to the above, and may be a narrower range, for example, until the shoulder position is detected, or until a position lowered several cm after the shoulder position is detected.

This inductance change is output as a voltage change by the detection circuit (109). The detection circuit (109) transmits the change to the microcomputer (101), and the shoulder position is detected by comparison with a pattern (described later) stored in advance in the microcomputer (101).
[0033]
Shoulder position detection operation The shoulder position is detected by moving the massage unit (30) to the upper end of the backrest (13) or to the upper part of the backrest (13) exceeding the shoulder position of the user. As shown in FIG. 9, it starts from the state where the kneading balls (41) (41) on the upper side of the treatment fingers (40) (40) are projected forward.
A detection operation is performed by driving the elevating motor (61) to move the massage unit (30) downward.
While moving the massage unit (30) from the top to the bottom, the voltage waveform due to the inductance change of the coil (71) is taken out from the detection circuit (109). The average value of the output voltage waveform has a certain characteristic, depending on the treatment area of the person in contact with the massaging ball (41), and the output voltage value is transferred from the detection circuit (109) to the microcomputer (101). The position of the shoulder of the user is specified by transmitting and comparing with the output voltage value stored in advance as shown in FIG. In FIG. 8, a state where the treatment arm (42) is most inclined forward is set to 0V.
When the shoulder position is detected, the identified shoulder position is stored in the memory of the microcomputer (101), and is referred to when, for example, a rolling massage or a shoulder hitting massage is performed. Thereafter, when the massage unit (30) moves to an intermediate height position of the backrest (13), the massage motor (51) is driven to retract the treatment fingers (40) (40) (shown by dotted lines in FIG. 9). ). The treatment finger (40) (40) may be retracted immediately after detecting the shoulder position, or the treatment finger (40) (40) may be moved after the massage unit (30) is moved after the shoulder position is detected. May be retreated.
By retreating the treatment fingers (40) and (40), as shown in FIGS. 12 (a) and 12 (b), even if the treatment fingers (40) and (40) hit the waist of the user, etc. Since the position of the person's body does not change, the shoulder position does not shift before and after detection.
[0034]
