Description

Chair type massage machine

Technical Field

The present invention relates to a chair-type massage machine including armrest portions and a footrest.

Background

In recent years, various chair-type massage machines having armrest portions and ottomans have been developed (see, for example, japanese patent application laid-open No. 2005-152260).

The massage machine proposed in jp 2005-152260 a can perform stretching treatment on the arm of the person to be treated when the backrest is laid down backward. However, since the armrest portion is stationary, the arm portion of the person to be treated, which is the extension treatment target, is not moved, and the body of the person to be treated, which is not the extension treatment target, is moved, thereby realizing extension treatment. Such stretching treatment may bring discomfort to the person to be treated.

Detailed Description

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is a front view of a chair-type massage machine 1 (hereinafter, referred to as "massage machine 1") according to an embodiment. Fig. 2 is a side view of the massage machine 1 as viewed from the left. Fig. 3 is a side view of the armrest portion 5L and the coupling portion 7L of the massager 1 as viewed from the right. In fig. 1 to 3 and fig. 6 to 7 described later, only the members constituting the frame of the massage machine 1 are illustrated.

In the following description, the front side (front side) of the massager 1 sitting in the non-tilted state of the backrest 3 as viewed from the user is referred to as "front side", and the rear side (rear side) of the massager 1 sitting in the non-tilted state of the backrest 3 as viewed from the user is referred to as "rear side". The upper side (head side) of the massager 1 sitting in the non-tilted state of the backrest 3 as viewed by the user is referred to as "upper side", and the lower side (foot side) of the massager 1 sitting in the non-tilted state of the backrest 3 as viewed by the user is referred to as "lower side". The right side of the massager 1 sitting on the backrest 3 in an unrotated state as viewed from the user is referred to as the "right side", and the left side of the massager 1 sitting on the backrest 3 in an unrotated state as viewed from the user is referred to as the "left side".

The massage machine 1 includes: a seat 2, a backrest 3, a pair of left and

right base portions

4L and 4R, a pair of left and

right armrest portions

5L and 5R, a footrest 6, and a pair of left and right connecting

portions

7L and 7R. The backrest portion 3, the

armrest portions

5L and 5R, and the ottoman 6 are attached to a main body portion having the seat portion 2 and the

base portions

4L and 4R.

The seat 2 supports the buttocks and thighs of the patient.

The backrest 3 supports the shoulder, waist, and back of the person to be treated. The backrest 3 is attached to the rear end of the seat 2 so as to be rotatable about a supine rotation axis extending in the left-right direction. A massage unit (not shown) having a treatment tool is provided in the backrest 3. The massage unit is guided by a guide rail (not shown) provided in the backrest 3 and ascends and descends in the longitudinal direction of the backrest 3. The guide rail may be extended to the rear of the seat 2 so that the massage unit is raised and lowered in the longitudinal direction of the seat 2 and the backrest 3. The massage unit is provided with: a treatment member; a kneading drive mechanism for kneading the therapeutic member; and a knocking drive mechanism for knocking the treatment member.

The base portion 4L is provided standing on the left side of the seat 2 and supports the armrest portion 5L. The base portion 4R is provided standing on the right side of the seat 2 and supports the armrest portion 5R.

The armrest portion 5L has a recess that is recessed downward. The recessed portions of the armrest portions 5L receive and support the left forearm and the left hand of the person to be treated. An airbag (not shown) is provided in the recess of the armrest portion 5L. The left forearm and the left hand of the person to be treated are massaged by the expansion and contraction of the air bag provided in the recess of the armrest portion 5L. When the airbag provided in the recess of the armrest portion 5L is inflated to a predetermined level or more, at least a part of the left forearm and the left hand of the person to be treated is fixed to the armrest portion 5L. The armrest portion 5L may have a function of supporting at least a part of the left forearm and the left hand of the person to be treated, without supporting the whole of the left forearm and the left hand of the person to be treated. Therefore, the "arm rest portion for supporting the forearm and hand of the person to be treated" described in the above-mentioned technical means may have a function of supporting at least a part of the forearm and hand of the person to be treated, without supporting the forearm and hand of the person to be treated. That is, the term "armrest portion for supporting the forearm and hand of the person to be treated" as used in the claims means an "armrest portion for supporting at least a part of the forearm and hand of the person to be treated".

Unlike the present embodiment, treatment means other than the airbag may be provided in the recess of the armrest portion 5L, or treatment means may not be provided in the recess of the armrest portion 5L. When no airbag is provided in the recess of the armrest portion 5L, it is desirable to provide a fixing mechanism other than an airbag or an auxiliary mechanism for assisting fixing. Examples of the fixing means other than the air bag include a fixing band wound around the wrist of the person to be treated. Examples of the assisting mechanism include a grip portion to be gripped by a user.

The armrest portion 5R is bilaterally symmetrical to the armrest portion 5L, and supports the right front arm and the right hand of the person to be treated.

The footrest 6 accommodates the lower leg and the foot of the person to be treated. The ottoman 6 is attached to the main body portion of the massager 1 so as to be rotatable about a rotation axis AX1 extending in the left-right direction. The ottoman 6 includes a mechanism (extending mechanism) that extends in the longitudinal direction of the lower leg portion of the person to be treated, i.e., in the direction from the knee to the ankle of the person to be treated (the direction parallel to the direction DR1 shown in fig. 2, 6, and 7). The elongation mechanism can be realized by, for example, a cylinder whose longitudinal direction is parallel to the direction DR1 and an actuator that drives the cylinder. The footrest 6 may have a function of accommodating at least a part of the lower leg portion and the foot of the person to be treated, without accommodating the whole of the lower leg portion and the foot of the person to be treated. Therefore, the "footrest for accommodating the lower leg portions and the feet of the person to be treated" described in the above-mentioned technical means may have a function of accommodating at least a part of the lower leg portions and the feet of the person to be treated, without accommodating all of the lower leg portions and the feet of the person to be treated. That is, the term "footrest for accommodating the lower leg portion and the feet of the subject" as used in the claims means "a footrest for accommodating at least a part of the lower leg portion and the feet of the subject".

An air bag is arranged on the footrest 6. The lower leg portion and the feet of the person to be treated are massaged by the expansion and contraction of the air bag provided in the ottoman 6. When the air bag provided in the ottoman 6 is inflated to a predetermined level or more, at least a part of the lower leg and the feet of the person to be treated are fixed to the ottoman.

Unlike the present embodiment, a treatment mechanism other than the air bag may be provided in the ottoman 6, or the treatment mechanism may not be provided in the ottoman 6. In the case where the ottoman 6 is not provided with an airbag, it is desirable to provide a fixing mechanism other than the airbag. Examples of the fixing means other than the air bag include a fixing band wound around the ankle of the person to be treated.

The connecting portion 7L connects the armrest portion 5L and the ottoman 6. The coupling portion 7L has a rod shape. One end of the connecting portion 7L is attached to a front lower portion of the armrest portion 5L so as to be rotatable about a second rotation axis AX2 extending in the left-right direction. The other end of the connecting portion 7L is attached to the left side surface of the ottoman 6 so as to be rotatable about a third rotation axis AX3 extending in the left-right direction.

The connecting portion 7R connects the armrest portion 5R and the ottoman 6. The coupling portion 7R has a rod shape. One end of the connecting portion 7R is attached to a front lower portion of the armrest portion 5R so as to be rotatable about a second rotation axis AX2 extending in the left-right direction. The other end of the connecting portion 7R is attached to the right side surface of the ottoman 6 so as to be rotatable about a third rotation axis AX3 extending in the left-right direction.

Fig. 4 is a block diagram showing a control system that controls the operation of the massage machine 1. The massage machine 1 includes: the seat back device includes a storage unit 11, a control unit 12, an operation unit 13, drive circuits 14 to 18, a seat back actuator 19 for rotating the seat back 3, a ottoman actuator 20 for rotating the ottoman 6, an extension mechanism 21 for the ottoman 6, an air pump 22, and an electromagnetic valve group 23.

The storage unit 11 stores programs and data necessary for the control unit 12 to control the operation of the massage machine 1. The control unit 12 controls the operation of the massage machine 1 based on the signal output from the operation unit 13.

The control unit 12 controls the backrest actuator 19 via the drive circuit 14. The controller 12 controls the ottoman actuator 20 via the drive circuit 15. The controller 12 controls the elongation mechanism 21 of the ottoman 6 via the drive circuit 16. The control section 12 controls the air pump 22 via the drive circuit 17. The control unit 12 controls the solenoid valve group 23 via the drive circuit 18. The solenoid valve group 23 includes a plurality of solenoid valves.

Each electromagnetic valve is disposed between the air pump 22 and at least one air bag. For example, when the electromagnetic valve is in the first state and the air pump 22 is in communication with the airbag, air is supplied from the air pump 22 to the airbag via the electromagnetic valve. Thereby, the balloon is inflated. On the other hand, when the solenoid valve is in the second state and the outside communicates with the airbag, the air in the airbag is discharged to the outside through the solenoid valve. Thereby, the air of the airbag is released and the airbag is contracted. In addition, when the electromagnetic valve is in the third state, the air bag is not communicated with the air pump 22 and the outside, and the air quantity in the air bag is kept.

Fig. 5 is a flowchart showing the stretching treatment operation of the massage machine 1. The massager 1 is controlled by the control unit 12 to perform the stretching treatment operation shown in fig. 5.

At the start of the stretching treatment operation shown in fig. 5, the massage machine 1 is in the state shown in fig. 2. That is, at the start time of the stretching treatment motion shown in fig. 5, the first rotation axis AX1 coincides with the second rotation axis AX2 and the direction DR1 is along the lower direction (gravity direction). At the start of the stretching treatment operation shown in fig. 5, the air in the air cells provided in the

armrest portions

5L and 5R and the air in the air cells provided in the ottoman 6 are released to the outside.

First, the control unit 12 rotates the ottoman 6 by a predetermined amount from the rear toward the front (step S10). In the following description, the predetermined amount is 90 °, but this value is merely an example, and the predetermined amount may be 45 ° or the like, for example. At the time point when the processing of step S10 is completed, the massage machine 1 is in the state shown in fig. 6.

In the process of step S10, the first rotation axis AX1 coincides with the second rotation axis AX2, and therefore, although the

armrest portions

5L and 5R are coupled to the ottoman 6, the

armrest portions

5L and 5R do not move relative to the

base portions

4L and 4R when the ottoman 6 rotates.

In step S20 subsequent to step S10, the control unit 12 inflates the airbags provided to the

armrest portions

5L and 5R and the airbag provided to the ottoman 6 while maintaining the state shown in fig. 6.

At the time point when the processing in step S20 is completed, at least a part of the left forearm and the left hand of the treatment subject is fixed to the armrest 5L, at least a part of the right forearm and the right hand of the treatment subject is fixed to the armrest 5R, and at least a part of the lower leg and the foot of the treatment subject is fixed to the ottoman 6.

In step S30 subsequent to step S20, the control unit 12 extends the ottoman 6 while maintaining the inflated states (air volumes) of the airbags provided to the

armrest portions

5L and 5R and the airbag provided to the ottoman 6 at the time when the processing in step S20 is completed. At the time point when the processing of step S30 is completed, the massage machine 1 is in the state shown in fig. 7.

At the time when the process of step S30 is completed, the ottoman 6 moves in the direction DR1 as compared with the time when the process of step S20 is completed. Thereby, the stretching treatment is performed on the lower leg and the foot of the person to be treated.

Further, since the

armrest portions

5L and 5R and the ottoman 6 are coupled by the

coupling portions

7L and 7R, the

armrest portions

5L and 5R move relative to the

base portions

4L and 4R as the ottoman 6 moves in the direction DR 1. Specifically, the

armrest portions

5L and 5R slide on the upper surfaces of the

base portions

4L and 4R, and move obliquely forward and upward in a direction DR2 including a front-rear direction component and a vertical direction component. Thereby, stretching treatment is performed on the forearm and hand of the person to be treated. Further, since the massage machine 1 includes the

connection portions

7L and 7R, the

armrest portions

5L and 5R can be moved relative to the

base portions

4L and 4R in conjunction with the movement of the footrest 6 without providing an actuator dedicated to the

armrest portions

5L and 5R.

In step S40 subsequent to step S30, the control unit 12 releases the extended state of the ottoman 6 and returns the state of the massage machine 1 to the state at the start time of step S30. Therefore, at the time point when the processing of step S40 is completed, the massage machine 1 returns to the state shown in fig. 6. In order to secure a sufficient time for the stretching treatment, a predetermined waiting time may be set between the time when the process of step S30 is completed and the time when the process of step S40 is started.

In step S50 subsequent to step S40, the control portion 12 contracts the airbags provided to the

armrest portions

5L and 5R and the airbag provided to the ottoman 6. At the time point when the processing in step S50 is completed, the left forearm and the left hand of the treatment subject are not fixed to the armrest 5L, the right forearm and the right hand of the treatment subject are not fixed to the armrest 5R, and the lower leg and the foot of the treatment subject are not fixed to the ottoman 6.

In step S60 subsequent to step S50, the controller 12 rotates the ottoman 6 by a predetermined amount from the front toward the rear. At the time point when the processing of step S60 is completed, the massage machine 1 returns to the state shown in fig. 2.

In the process of step S60, the first rotation axis AX1 coincides with the second rotation axis AX2, and therefore, although the

armrest portions

5L and 5R are coupled to the ottoman 6, the

armrest portions

5L and 5R do not move relative to the

base portions

4L and 4R when the ottoman 6 rotates.

When the process of step S60 is completed, the flow action shown in fig. 5 ends.

It should be understood that the above-described embodiments are merely illustrative in all respects and not restrictive, and that the technical scope of the present invention is shown not by the description of the above-described embodiments but by the scope of the claims, and includes all modifications that fall within the meaning and scope equivalent to the scope of the claims.

For example, unlike the present embodiment, the processing of steps S30 to S40 may be repeated several times and converted to step S50. For example, unlike the present embodiment, the execution order of step S10 and step S20 may be exchanged. For example, unlike the present embodiment, the execution order of step S50 and step S60 may be exchanged.

For example, the backrest portion 3 may be tilted rearward as the ottoman 6 is rotated from the rear to the front.

For example, the massage machine 1 may be configured such that the direction DR1 is parallel to the direction DR 2. By adjusting at least one of the rotation range of the ottoman 6 and the orientations of the upper surfaces of the

base portions

4L and 4R, a structure in which the direction DR1 can be made parallel to the direction DR2 can be realized. By extending the ottoman 6 in a state where the direction DR1 is parallel to the direction DR2, the amount of movement of the

armrest portions

5L and 5R with respect to the

base portions

4L and 4R becomes maximum, and therefore the stretching effect on the forearm and hand of the person to be treated can be improved.
