Description

  The present invention relates to a chair-type massage machine including a leg placement portion that can project forward from a front portion of a seat portion.

The chair-type massage machine includes a seat, a backrest provided at the back of the chair, a leg rest (footrest) provided at the front of the chair, and armrests provided on the left and right sides of the seat Some have parts. In such a chair type massage machine, the massage mechanism capable of giving massage to the user is appropriately arranged in the backrest part, the seat part, the armrest part, etc., but also in the leg rest part. Some have a mechanism.
As a massage mechanism, for example, a treatment element (smearing ball) operated by a motor or the like massages the user's back or the like, or an air cell that expands and contracts by air supply / exhaust massages the user's leg or the like. is there.
In such a chair-type massage machine, there is one in which a leg placement portion is attached to the front portion of the chair so as to be vertically rotatable. In this chair type massage machine, the leg resting portion is lowered to be hung downward, and the leg resting portion is raised so as to protrude forward from the front portion of the seat portion.
In addition, as a chair type massage machine in which the leg resting part can protrude forward, it is placed on the seat part when the leg resting part is not used for leg massage in order to save space. The thing which can accommodate the said leg mounting part is proposed (for example, patent document 1). When this chair type massage machine is used for leg massage, the leg placement part is rotated and deployed so that the leg placement part protrudes in front of the seat part, A user's leg will be mounted on the leg mounting surface of this leg mounting part. And when not using it for a leg massage, if a leg mounting part is turned and it turns over in the state where the leg mounting surface turned down and it accommodates on a seat part, it will be in the accommodation state of a leg mounting part. . Therefore, the accommodation state is a state in which the back surface of the leg placement surface faces upward, and the user can sit on the back surface and use it as a chair.

JP-A-9-266933

  In such two types of chair type massage machines, the upper surface of the armrest portion is higher than the seat surface (upper surface) of the seat portion when the leg placement portion protrudes forward. Therefore, it is difficult for the user to sit on the chair-type massage machine in this state because the leg placement part protrudes from the floor and protrudes from the front of the chair. Therefore, the user needs to ride over the armrest from the side and sit on the seat. That is, when seated, the armrest part is in the way, and there is a problem that it is difficult for the user to sit on the chair type massage machine.

  This invention is made in view of the said problem, and when the leg mounting part is the state protruded ahead, it aims at providing the chair type massage machine which can make it easy to sit down. To do.

In order to achieve the above object, a chair type massage machine of the present invention has a seat part, armrest parts provided on both right and left sides of the seat part, a massage mechanism, and projects forward from the front part of the seat part. A chair-type massage machine including a leg placement portion that can be shaped, and a state in which an upper surface of the armrest portion is higher than an upper surface of the seat portion is a normal state of the armrest portion. In the state where the leg placement portion is projected forward, the armrest portion can be lowered so that the upper surface thereof is at a position lower than the normal state.
According to this configuration, when a user sits on a chair-type massage machine with the leg placement portion protruding forward, the upper surface of the armrest portion is higher than the upper surface of the seat portion in a normal state. According to this configuration, the height of the armrest portion can be reduced. As a result, the user can sit on the upper surface of the seat over the armrest with the height lowered, and the seating operation is facilitated. In other words, in the state where the leg resting portion protrudes forward, it is difficult for the user to sit on the seat from the front (front) of the chair, but this configuration facilitates sitting from the side of the chair. Let
And since the upper surface of the armrest portion is higher than the upper surface of the seat portion in the normal state, the user sitting on the upper surface of the seat portion of the chair type massage machine in which the leg resting portion is in the unfolded state Can be placed on the elbow.

In the chair-type massage machine, the leg placement portion is rotatably provided at the front portion of the chair so that the accommodation state is accommodated above the seat portion and between the armrest portions, It can be set as the structure which can be changed to the expansion | deployment state made into the protruding shape from the front part of a seat part ahead.
In this case, when the leg placement portion is not used for leg massage, the leg placement portion can be accommodated above the seat portion. And when using a leg mounting part for leg massage, the said leg mounting part is rotated and expanded so that a leg mounting part may be in the state of projecting ahead of a seat part, and this leg mounting part The user's leg can be placed on the leg mounting surface. Thereby, the chair type massage machine which can aim at space saving can be comprised.

  Further, in a state where the leg placement portion protrudes forward, the armrest portion can be lowered until the height position of the upper surface of at least the front portion is equal to or lower than the height position of the upper surface of the seat portion. Is preferred. According to this, the height position of the upper surface in the front portion of the armrest portion is lowered, and the seating operation from the front side is facilitated.

  In the normal state, it is preferable that the height position of the upper surface of at least the front portion of the armrest portion is equal to or lower than the height position of the upper surface of the leg placement portion in the housed state. According to this, the front part of an armrest part does not become obstructive in the accommodation state of a leg mounting part, and it can sit down easily from the side part front.

Further, a spring member is interposed between the armrest portion and the chair body portion side, the armrest portion can be lowered by being pushed down against the elastic force of the spring member, and the It is preferable that the armrest portion can be returned to the normal state by an elastic force of a spring member.
According to this, the structure which makes an armrest part descendable is simple, and the operation | movement to which it descends is easy. That is, if the user performs an action to get on the armrest, the weight acts on the armrest, and the armrest naturally falls because the weight resists the elastic force of the spring member.
When the user sits on the seat over the lowered armrest, the weight acting on the armrest is released, and the armrest is automatically restored by the elastic force of the spring member. Can return to normal state.

  In addition, the armrest portion is divided into front and rear directions and is constituted by a plurality of armrest segments, and preferably at least one armrest segment can be lowered. According to this, since the part to be lowered of the armrest part can be reduced and the part to be operated can be lightened, it is possible to reduce the configuration and ability for the descent operation.

  Moreover, it is preferable that the armrest portion can be raised so that the upper surface thereof is at a position higher than the normal state. When the leg rest is in the unfolded state, the armrest is at an appropriate armrest height in the normal state, but when the leg rest is in the stowed state, the surface on which the user is seated is increased by the thickness of the leg rest. Therefore, the armrest height is lowered (the armrest is lost). However, according to this configuration, the height of the armrest portion can be increased even when the leg placement portion is in the housed state, and an appropriate armrest height can be obtained.

  In addition, the armrest portion is divided into a front-rear direction and is composed of a plurality of armrest segments, and preferably at least one armrest segment can be raised. According to this, since the part to be raised of the armrest part is reduced and the part to be operated can be lightened, the configuration and ability for the raising operation can be reduced.

  According to the chair type massage machine of the present invention, since the armrest portion can be lowered, it is possible to prevent the seating operation from being disturbed by lowering the armrest portion during the seating operation. And since the upper surface of the armrest portion is higher than the upper surface of the seat portion in the normal state, the user seated on the upper surface of the seat portion places the elbow on the armrest portion in the deployed state of the leg rest portion. be able to.

Embodiments of the present invention will be described below with reference to the drawings.
FIG.1 and FIG.3 is a perspective view of the chair type massage machine which is one Embodiment of this invention, FIG.2 and FIG.4 is the side view.
This chair type massage machine has a seat part 1, a backrest part 2 provided at the rear part of the chair, a leg rest part (footrest) 3 provided at the front part of the chair, and left and right sides of the seat part 1, respectively. The armrest part 4 provided is provided.
As shown in FIG. 1, the seat 1 is provided on the upper portion of the chair body 9 that is placed on the floor surface, and the upper surface 1 a of the seat 1 can be used as a seat. The backrest part 2 is rotatably attached to the rear part of the chair main body part 9, and can be in a reclining state (not shown) that has fallen backward from the standing state shown.

  The leg placement unit 3 has a massage mechanism (not shown) that can massage the user, and is rotatably attached to the front portion of the chair body 9. Thereby, the leg mounting part 3 is accommodated in the housing state (FIGS. 3 and 4) accommodated above the seat part 1 and between the armrest parts 4, and the unfolded state projecting forward from the seat part 1. (Shown in FIGS. 1 and 2). The massage mechanism is an air cell (not shown) that expands and contracts by supplying and discharging air. The leg placing part 3 has a leg placing surface 3a on which a user's leg is placed in the unfolded state.

1 and 2 is a state in which the leg placement surface 3a of the leg placement portion 3 is directed upward, and the leg placement portion 3 projects horizontally in the front portion of the seat portion 1 forward. It is in the state. In this unfolded state, the user seated on the chair type massage machine can place his / her leg on the leg placement surface 3a and can receive leg massage by the massage mechanism on the leg placement surface 3a.
On the other hand, the accommodation state is a state in which the leg placement surface 3a is directed downward, and the leg placement portion 3 is accommodated on the seat portion 1 and between the left and right armrest portions 4. That is, the back surface 3b that is the opposite side surface of the leg placement surface 3a is used as a seating surface.
In addition, the seat surface in which the leg placement unit 3 is in the unfolded state, that is, the seat surface constituted by the upper surface 1a of the seat unit 1 is also referred to as a seat surface 11 at the time of deployment, That is, the seat surface constituted by the back surface 3b opposite to the leg placement surface 3a of the leg placement unit 3 is also referred to as a seating surface 12 when housed.

The leg placement part 3 can be rotated to be in both the deployed state and the accommodated state. In the deployed state, the leg placement part 3 is separated from the floor surface and protrudes horizontally. The user can take a sitting posture with his legs extended. In the accommodated state, the seated posture can be taken in which the knee is bent and the sole can be brought into contact with the floor surface while the user is seated on the seating surface 12 at the time of accommodation.
The leg placement part 3 in the unfolded state is provided with two recesses 13 that can respectively accommodate the left and right legs of the user seated (sitting) on the seating surface 11 during deployment (see FIG. 1). . Although not shown, an air cell as a massage mechanism that expands and contracts by air is provided at each of the lower surface and both side surfaces of each recess 13 so that the legs arranged in the recess 13 can be massaged.

  In this chair type massage machine, the state where the upper surface 4 a of the armrest portion 4 is higher than the upper surface 1 a of the seat portion 1 is the normal state of the armrest portion 4. That is, for example, when not in use, the armrest portion 4 is in this normal state. Furthermore, in this normal state, as shown in FIG. 4, the upper surface 4a of the armrest portion 4 (at least in the front portion) is substantially the same as the upper surface of the leg mounting portion 3 in the accommodated state (the seat surface 12 when accommodated). Further, the height position of the upper surface 4a (at least at the front portion) of the armrest portion 4 is set to be equal to or lower than the height position of the upper surface of the leg placement portion 3 in the accommodated state. preferable. Thus, a chair without the armrest portion 4 can be configured in the accommodated state of the leg placement portion 3. And the armrest part 4 does not get in the way, and the user can sit down easily from the side.

And the armrest part 4 of this chair type massage machine can be lowered so that the upper surface 4a of the armrest part 4 is lower than the normal state when the leg placement part 3 is in the unfolded state, The upper surface 4a is configured to be able to be lowered to a position substantially the same as the upper surface 1a of the seat portion 1 (the seat surface 11 when deployed). In particular, when the leg resting portion 3 is in the unfolded state, the armrest portion 4 can be lowered until the height position of the upper surface 4a at least at the front portion is equal to or lower than the height position of the upper surface 1a of the seat portion 1. Is preferred.
In the normal state, the upper surface 4a of the armrest portion 4 is at a position higher than the seat surface 11 when deployed, but with this configuration, when the user sits on the chair type massage machine with the leg rest portion 3 deployed, The height of the armrest portion 4 can be lowered, and the user can sit on the seat surface 11 when unfolding over the lowered armrest portion 4 and the seating operation is facilitated. Then, with the armrest portion 4 in a normal state, the user seated on the seat surface 11 at the time of deployment can place the elbow on the upper surface 4a of the armrest portion 4 at a position higher than the seat surface 11, and an easy posture And can.

Further, as shown in FIGS. 1 and 2, the left and right armrest portions 4 are provided over the entire length of the seat portion 1 in the front-rear direction. The armrest portion 4 is divided in the front-rear direction to provide three armrests. It consists of segments 5, 6 and 7, and the foremost one can be lowered. That is, the foremost armrest segment 5 can be lowered, and can be lowered until the height position of the upper surface of the armrest segment 5 is equal to or lower than the height position of the seat surface 11 at the time of deployment. Although not shown, in the present invention, portions other than the foremost portion (armrest segment 5) of the divided armrest segments may be lowered, or a plurality of these including the foremost portion are independent of each other. Then, it may be configured to be able to descend. That is, at least one armrest segment (including the foremost portion) can be lowered. Furthermore, the armrest portion 4 may be configured not to be a divided structure (not shown) but to be lowered as a whole as a single unit.
In addition to the three divisions, the armrest portion 4 may be divided into, for example, two front and rear divisions, and the division may be equal division so that the dimensions in the front and rear directions are equal. May be.

  In the comparison of the height position of the upper surface 4a of the armrest portion 4 and the seating surface 11 when deployed, and the comparison of the height position of the upper surface 4a of the armrest portion 4 and the seating surface 12 of the housing, the upper surface 4a of the armrest portion 4 as a whole. When it is curved, the horizontal plane including the highest point on the upper surface 4a is defined as the “upper surface”. Further, “substantially the same height” naturally includes the same height, but also includes a state that differs by a small dimension. That is, as shown in FIG. 5, in the upper part of the armrest portion 4, within the height direction range A of the point b that is 10 cm downward from the highest point t of the armrest portion 4, When there is a position in the height direction (uppermost point) of the seating surface 12 at the time of accommodation, it is said that it is at “substantially the same height”. That is, when the difference between the highest point t on the upper surface 4a of the armrest portion 4 and the height position of the seat surface 11 when deployed or the seat surface 12 when accommodated is ± 5 cm, the height is substantially the same. Further, this “substantially the same height” will be explained from another viewpoint. It is accommodated within an upper and lower range (± 5 cm) of 10% of the height dimension (for example, 50 cm) from the floor surface to the seating surface 12 at the time of accommodation. In the case where the hour seat surface 12 and the upper surface 4a of the armrest portion 4 are present, they are approximately the same height. In addition, when the seat surface 11 at the time of deployment and the upper surface 4a of the armrest portion 4 are within the vertical range of 10% of the height dimension from the floor surface to the seat surface 11 at the time of deployment, the height is almost the same.

  Next, the lowering mechanism 15 that allows the armrest portion 4 to be lowered will be described. FIG. 6 is a perspective view showing an armrest segment 5 that can be lowered and a lowering mechanism 15 provided on the inner side thereof, and FIGS. 7 and 8 are sectional views thereof. The lowering mechanism 15 has a spring member 10 interposed between the armrest segment 5 and the chair main body 9 side, and the armrest segment 5 is pushed down against the elastic force of the spring member 10. The armrest portion 4 is configured to be able to be lowered and to be automatically returned to the normal state by the elastic force of the spring member 10. The lowering mechanism 15 attached to the armrest segment 5 is connected to the chair body 9 while being housed in a recess 17 formed inside the side surface of the armrest segment 5. Thereby, the lowering mechanism 15 can be made difficult to see from the outside.

  More specifically, the lowering mechanism 15 includes a base member 16 that is fixed to the attachment portion 9a of the chair body 9, and a fixing member 18 that has a hole 18a that is fixed to the base member 16 and penetrates in the vertical direction. The shaft 20 is inserted into the hole 18a and the upper end is fixed to the upper surface 19 of the concave portion 17 of the armrest segment 5, and the shaft 20 is linear in the vertical direction, and the fixing member 18 and the armrest segment are externally fitted to the shaft 20. A coil spring as a spring member 10 provided between the upper surface 19 of the concave portion 17 and a guide through hole 21 which is vertically fixed to the armrest segment 5 and penetrates in the vertical direction formed in the base member 16. A linear rail member 22 that is inserted into the rail is provided. In a state where a load other than its own weight is not applied to the armrest segment 5, that is, in the normal state, as shown in FIG. 7, the upper surface of the armrest segment 5 is positioned higher than the seat surface 11 when deployed. Although not shown, the upper surface of the armrest segment 5 is set to a height equal to or lower than the upper surface (the seating surface 12 at the time of accommodation) of the leg placement unit 3 in the accommodated state.

When a downward force is applied to the armrest segment 5, the coil spring 10 is compressed between the upper surface 19 of the concave portion 17 of the armrest segment 5 and the upper surface of the fixing member 18, and the armrest segment 5 is elasticized by the coil spring 10. Descent is possible against this. At this time, the rail member 22 fixed to the armrest segment 5 is guided by the guide through hole 21 of the base member 16 fixed to the chair main body 9 side, and the armrest segment 5 is stabilized straightly downward. I can descend.
According to such a configuration of the lowering mechanism 15, if the user performs an action to get on the armrest segment 5, the weight acts on the armrest segment 5, and the weight resists the elastic force of the coil spring 10. This naturally lowers the armrest segment 5. Then, if the user sits on the seat surface 11 when unfolding over the armrest segment 5, the weight acting on the armrest segment 5 is released, and the armrest segment 5 is restored to the original normal by the elastic force of the coil spring 10. It can automatically return to the state.

  Furthermore, in this chair type massage machine, as shown in FIG. 3 and FIG. 4, the armrest portion 4 can be raised to a position where the upper surface 4a is higher than the normal state. As described above, the armrest portion 4 is divided into the front and rear directions and is composed of three armrest segments 5, 6, and 7, one of which can be raised from the normal state. In other words, the middle armrest segment 6 can be raised, and the upper surface of the armrest segment 6 is set to be approximately the same height (or lower position) as the seating surface 12 when housed in a normal state. The segment 6 can be raised from the normal state.

And as shown in FIG. 4, the armrest part 4 (armrest segment 6) raises the height position of the upper surface to the height corresponding to the height position of the user's elbow seated on the seating surface 12 at the time of accommodation. Is possible. The height is adjustable and can correspond to the elbow height position due to the difference in the height of the user. That is, although not shown, the ascending mechanism has a height adjusting means, and the height adjustment range of the armrest portion 4 is determined in relation to the seating surface 12 at the time of accommodation. In the accommodated state of the leg placing part 3, the upper surface 4a of the armrest part 4 can be made higher than the back face 3b of the leg placing part 3 used as a seating surface, that is, the height of the seating surface 12 when housed. That is, in the accommodated state shown in FIG. 4, the height (maximum height position) of the armrest portion 4 can be adjusted to be higher than the height (maximum height) of the seating surface 12 during accommodation by a height difference h1. The height difference h1 is preferably set to about 100 mm to 200 mm in consideration of the height required for the armrest function.
The rise of the armrest portion 4 can be at least one of the divided armrest segments 5, 6, and 7, but the armrest segment corresponding to the elbow of the user seated on the seating surface 12 at the time of accommodation is selected. It is rising. That is, in FIG. 4, it is preferable that the middle armrest segment 6 can be raised. Moreover, although not shown in figure, the armrest part 4 may be made into an integral thing and the whole may be raiseable.

  Further, the lifting mechanism will be described. As shown in the figure when the armrest portion 4 shown in FIG. 9 is viewed from the inside, the armrest segment 6 includes an armrest body portion 27 fixed to the chair body portion 9 side, and an upper portion thereof. And an armrest upper portion 26 on which the user's elbow is placed. The armrest upper portion 26 can be configured to rise with respect to the armrest main body portion 27 in a fixed state. That is, the elevating member 28 of the elevating mechanism is moved up and down along the recessed groove formed in the armrest main body 27, and the armrest upper portion 26 fixed to the upper portion of the elevating member 28 is moved up and down. ing. Thereby, the part which can be raised becomes small, the power (operating force) for operating can be small, and the raising mechanism can be made compact.

  Further, the lifting mechanism can hold the lifting member 28 at a predetermined height position by engaging the lifting member 28 and a part of the lifting member 28 with a part of the armrest main body 27. It has a lock part (not shown) and a lever member which can release engagement of this lock part. By operating a lever member (not shown), the elevating member 28 and the armrest main body 27 in the lock portion can be disengaged, and the elevating member 28 is moved with respect to the armrest main body 27 to obtain a desired height position. Thus, the relative position of the two can be held again by the lock member.

Further, with reference to FIG. 9, an attachment portion 9 a (see FIG. 7) fixed to the chair body portion 9 is a support member 29 that is long in the front-rear direction, and the armrest portion 4 is attached to the support member 29. . Specifically, in the foremost armrest segment 5, the base member 16 is fixed to a support member 29, and the armrest segment 5 can be lowered with respect to the support member 29. The armrest segment 6 in the middle portion has an armrest main body portion 27 fixed to a support member 29, and an armrest upper portion 26 can be raised with respect to the armrest main body portion 27. The last armrest segment 7 is fixed to the rear portion of the support member 29.
This armrest part 4 expands the leg placement part 3 and a part that can be raised to support the elbow of the user seated on the seating surface 12 when the leg placement part 3 is in the accommodated state. In order to be seated on the seating surface 11 when deployed, the armrest portion 4 has a portion that can be lowered so as not to obstruct, and the portion to be raised and the portion to be lowered are in the front-rear direction. It is in a different position. In this case, as shown in FIG. 9, if the armrest portion 4 is configured as a plurality of armrest segments 5, 6, and 7, it can be divided into dedicated portions that perform respective operations of ascending or descending. Or the structure for making it fall can be simplified.
The lowering mechanism 15 and the raising mechanism are not limited to the illustrated form, and may have other configurations.

  FIG. 10 and FIG. 11 are side views showing another chair type massage machine. The seat 51, the armrests 54 provided on the left and right sides of the seat 51, and the front of the chair are rotatably provided. The leg mounting part 53 currently provided and the backrest part 52 provided in the chair rear part so that rotation is possible are provided. The leg placement portion 53 has a massage mechanism and is provided rotatably at the front portion of the chair, so that the leg placement portion 53 is accommodated above the seat portion 51 and between the armrest portions 54. It is possible to change to the unfolded state that protrudes forward, and this is the same as the configuration of the chair type massage machine shown in FIGS. In addition, the configuration other than the armrest portion 54 is the same as the configuration of the chair-type massage machine shown in FIGS.

  The armrest portion 54 provided in the chair type massage machine has a lifting mechanism for changing the height, and the lifting mechanism is configured to accommodate the upper surface 54a in the expanded state of the leg placement portion 53. The height of the seating surface 62 can be almost the same as the height of the seating surface 62 (state shown in FIG. 10) or lower than the seating seating surface 62 (this lowered state is referred to as the lowered state). In the accommodated state of 53, the upper surface 54a of the armrest portion 54 can be adjusted to a position higher than the back surface 53b (the seat surface 62 when accommodated) of the leg placement portion 53 used as a seating surface (see FIG. 11). State, this raised state is called elevated state). That is, since the upper surface 54a of the armrest portion 54 can be made higher than the rear surface 53b of the leg placement portion 53 serving as a seat surface in the housed state, the armrest function by the armrest portion 54 can be exhibited. Furthermore, in the unfolded state, even if the thickness of the leg placement portion 53 is relatively large, it is possible to prevent the armrest portion 54 from becoming too high, and an armrest having an appropriate height can be obtained. Note that the upper surface 54a of the armrest portion 54 in this case is also the highest position of the upper surface 54a when the upper surface 54a of the armrest portion 54 is curved, as in FIGS. The horizontal plane that includes is the “upper surface”. Furthermore, “substantially the same height” naturally includes the same height, but also includes a state (± 5 cm) that differs by a small dimension.

  Further, the armrest portion 54 exists at a position near the rear portion in the front-rear direction of the seat portion 51 in the lowered state, and is configured to move upward and obliquely upward by the lifting mechanism. In this raised state, the horizontal position of the intermediate portion in the front-rear direction of the armrest portion 54 substantially coincides with the horizontal position of the intermediate portion in the front-rear direction of the seat portion 1, and the seat surface in which the intermediate portion in the front-rear direction of the armrest portion 54 is in the accommodated state. It corresponds to the elbow of the user sitting on (the seating surface 62 when housed). According to this, in the housed state, when the armrest part 54 is in the lowered state, the armrest part 54 is below the height of the seating surface 62 when housed, and exists at the rear part of the seat part 51. Is not present at the side front portion of the seat portion 51, the user can easily sit from the side front portion of the chair type massage machine. When the armrest portion 54 is raised, the armrest portion 54 located on the rear side moves forward and upward, so that the armrest portion 54 is in an appropriate armrest position.

  Furthermore, the front-rear direction shape of the upper surface 54a of the armrest portion 54 will be described. The armrest portion 54 has a highest top portion 55 at the center, and a forward downward inclined portion 56 inclined downward from the top portion 55 toward the front, A rear downward inclined portion 57 inclined downward from the top portion 55. Thereby, in the lowered state, the top portion 55 is substantially the same height as the seating surface 62 when housed and behind the intermediate portion in the front-rear direction of the seat portion 51. And the horizontal position is located in the middle part in the front-rear direction of the seat part 51, so that an appropriate armrest is obtained. The user can place the tip of the elbow in a downwardly inclined posture along the forward downward inclined portion 56, and can take an easy posture.

  FIG. 12 is a perspective view for explaining the configuration of the armrest portion 54. The armrest portion 54 is fixed to the chair body portion 59 (see FIG. 10) side in the same manner as that shown in FIG. And an armrest upper portion 66 on which the user's elbow is placed.
