In addition, the upper side (head side) seen from the massager 1 seated on the massage machine 1 with the backrest 3 not folded down is referred to as the "upper side" or "upper side". The lower side (leg side) seen from the massage recipient seated on the massage machine 1 is referred to as the "lower side" or "lower side." Further, the right side when viewed from the user sitting on the massage machine 1 is referred to as the "right side" or the "right side," and the left side when viewed from the user sitting on the massage machine 1 is referred to as the "left side."

The massage machine 1 includes a seat part 2, a backrest part 3, a side wall part 4, an armrest part 5, an operation part 6, a cord line 7, a stand 8, and an ottoman 9.

The seat portion 2 supports the buttocks and thighs of the user.

The backrest 3 supports the shoulders, hips, and back of the person being treated. The backrest 3 is reclining. In other words, the backrest 3 can rotate around a reclining rotation axis AX1 (see FIG. 5 described later) that extends in the left-right direction.

The backrest portion 3 includes a massage unit (not shown) and guide rails 3B and 3C extending along a surface 3A that contacts the shoulder and waist of the user. The massage unit moves up and down within the backrest 3 while being guided by guide rails 3B and 3C.

The side wall portions 4 are provided upright on both left and right sides of the seat portion 2.

The armrests 5 are provided on both the left and right sides of the seat 2 and are supported by the side walls 4. The armrests 5 support the arms of the person being treated. More specifically, the armrests 5 support the forearms of the person being treated.

Further, in this embodiment, the armrest portion 5 includes an inflatable airbag, and the forearm and hand of the user are treated using the airbag. That is, the armrest section 5 includes a treatment section for treating the forearm and hand of the user. Note that the treatment for the forearm and hand of the recipient is not limited to treatment using the airbag, but may be any treatment performed using physical means. That is, the treatment that the treatment section provided on the armrest 5 performs on the forearms and hands of the user is not limited to massaging the forearms and hands, but includes, for example, treatment that applies heat to the forearms and hands, and treatment that applies heat to the forearms and hands. It may also be a treatment that provides electrical stimulation. Therefore, the armrest portion 5 may be configured to include a treatment section that includes a treatment element, an airbag, a vibrator, a heater, an electrode pad, etc., either singly or in combination.

2 and 4 are front views schematically showing the frame etc. of the massage machine 1. FIG. 3 and 5 are side views schematically showing the frame and the like of the massage machine 1. FIG.

2 and 3 show the backrest 3 of the massage machine 1 in its most upright position. 4 and 5 show a state in which the backrest portion 3 of the massage machine 1 is in the most rearward position (fully reclined state).

The massage machine 1 includes a base frame 10. The base frame 10 is located below the seat 2 (not shown in FIGS. 2 to 5) and supports the seat 2.

The armrest 5 includes an upper frame 5A, a front arm 5B, and a rear arm 5C.

The upper frame 5A extends along the front-rear direction and extends downward toward the rear. The longitudinal direction of the upper frame 5A is the longitudinal direction of the armrest 5. The longitudinal direction of the armrest 5 can be expressed as the direction of a straight line passing through the user's elbow and wrist when the user places his or her forearm on the armrest 5.

The front arm 5B is a rectangular member when viewed from the side, and when the backrest 3 of the massage machine 1 is in its most upright position, it extends in the vertical direction and toward the rear as it goes upward.

The lower end of the front arm 5B is attached to the base frame 10 so as to be rotatable around a rotation axis AX2 that extends along the left-right direction. The upper end of the front arm 5B is attached to the upper frame 5A so as to be rotatable around a rotation axis AX3 that extends along the left-right direction.

The rear arm 5C is a rectangular member when viewed from the side, and extends along the up-down direction and toward the rear as it goes upward, when the backrest 3 of the massage machine 1 is in its most upright state.

The lower end of the rear arm 5C is attached to the base frame 10 so as to be rotatable around a rotation axis AX4 that extends along the left-right direction. The upper end of the rear arm 5C is attached to the upper frame 5A so as to be rotatable around a rotation axis AX5 that extends along the left-right direction.

The mounting position of the rear arm 5C on the base frame 10 is behind the mounting position of the front arm 5B on the base frame 10. Similarly, the attachment position of the rear arm 5C on the upper frame 5A is rearward than the attachment position of the front arm 5B on the upper frame 5A.

The arm length of the front arm 5B, that is, the length of the rectangular long side of the front arm 5B when viewed from the side, is longer than the arm length of the rear arm 5C, that is, the length of the rectangular long side of the rear arm 5C when viewed from the side. With such a configuration, the front arm 5B and the rear arm 5C can support the upper frame 5A so that the upper frame 5A extends along the front-rear direction and extends downward toward the rear.

The backrest portion 3 includes a frame 3D, a backing plate 3E, and a backing plate 3F. The backing plate 3E projects toward the left side from the left end of the frame 3D. The backing plate 3F projects toward the right side from the right end of the frame 3D.

The armrest part 5 is not attached to the backrest part 3. The rear part of the armrest part 5 can both contact and separate from the backrest part 3. In this embodiment, the rear end of the armrest 5 can both come into contact with and separate from the backrest 3. Note that, unlike this embodiment, the rear part of the armrest part 5 other than the rear end of the armrest part 5 may be able to both contact and separate from the backrest part 3.

As can be seen from FIGS. 3 and 5, a roller is provided at the rear end of the armrest 5. The rear end roller of the armrest portion 5 located on the left side can both contact and separate from the backrest portion 3 E of the backrest portion 3 . Similarly, the rear end roller of the armrest 5 located on the right side can both contact and separate from the backrest 3F.

When an external force is applied to the armrest 5 to separate the armrest 5 and the backrest 3, and the armrest 5 and the backrest 3 are separated, when the application of the external force to the armrest 5 is stopped, the armrest is separated. The armrest portion 5 moves rearward due to its own weight. The position of the center of gravity of the armrest portion 5 is designed so that such movement due to its own weight occurs.

Therefore, if no external force is applied to the armrest 5 to separate the armrest 5 and the backrest 3, the backrest actuator 11 is driven from the state in which the backrest 3 is in its most upright position as shown in FIGS. 2 and 3. The backrest part 3 is tilted by this, and the contact of the rear part of the armrest part 5 with the backrest part 3 is maintained until the backrest part 3 reaches the state shown in FIG. 4 and FIG. Ru. Furthermore, if no external force is applied to the armrest 5 to separate the armrest 5 and the backrest 3, the backrest actuator 11 is The backrest part 3 stands up due to the drive of the armrest part 5, and the contact of the rear part of the armrest part 5 with the backrest part 3 continues until the backrest part 3 reaches the most upright state shown in FIGS. 2 and 3. is maintained.

In other words, if no external force is applied to the armrest 5 to separate the armrest 5 and the backrest 3, the rear part of the armrest 5 will come into contact with the backrest 3 and move in conjunction with the reclining movement of the backrest 3. Then, the armrest portion 5 moves back and forth. Thereby, even if the backrest 3 is tilted, the person to be treated can use the armrest 5 without fully extending his or her elbow. In other words, when the backrest portion 3 is tilted, the arms of the user can be put into a relaxed state.

Moreover, since the upper frame 5A is supported by the front arm 5B and the rear arm 5C, the upper frame 5A moves while drawing a nearly arcuate trajectory as the front arm 5B and the rear arm 5C rotate with respect to the base frame 10. do. Therefore, the more the armrest 5 moves rearward, the larger the acute angle θ between the longitudinal direction of the armrest 5 and the bottom surface of the base frame 10, that is, the bottom surface of the massage machine 1, becomes larger. Thereby, even when the backrest part 3 is tilted, the user can use the armrest part 5 without greatly changing the angle of the elbow compared to when the backrest part 3 is upright. In other words, when the backrest portion 3 is tilted, the arms of the user can be further relaxed.

On the other hand, if an external force is applied to separate the armrest part 5 and the backrest part 3 so that the armrest part 5 and the backrest part 3 are separated, the rear part of the armrest part 5 can be separated from the backrest part 3. . In other words, when the user pushes his/her arm forward while placing it on the armrest 5, the armrest 5 can be moved forward. That is, in the massage machine 1, the position of the armrest 5 can be adjusted regardless of the position of the backrest 3. As a result, if the position of the armrest 5 according to the reclining movement of the backrest 3 is not appropriate due to the physique of the user, the preference of the user, etc., the armrest 5 can be adjusted by applying an external force to the armrest 5. Can be adjusted to the appropriate position.

The above embodiments should be considered to be illustrative in all respects and not restrictive, and the technical scope of the present invention is indicated by the claims rather than the description of the above embodiments. It should be understood that all changes that come within the meaning and range of equivalence of the claims are included.

Further, a regulating section 12 that regulates forward movement of the armrest section 5 may be added to the massage machine 1 described above. That is, the chair-type massage machine 1' (hereinafter referred to as "massage machine 1'") according to the modified example further includes a restriction part 12 that restricts forward movement of the armrest part 5. The massage machine 1' differs from the massage machine 1 in that it includes a regulating section 12, and is the same as the massage machine 1 in other respects.

By providing the restricting portion 12, it is possible to prevent the armrest portion 5 from moving too far forward.

FIG. 6 is a side view schematically showing an example of the frame etc. of the massage machine 1'. FIG. 7 is a side view schematically showing another example of the frame etc. of the massage machine 1'.

In the example shown in FIG. 6, the regulating part 12 moves the armrest part 5 further forward than when the rear part of the armrest part 5 is in contact with the backrest part 3 when the backrest part 3 is in the most upright state. The forward movement of the armrest part 5 is restricted to prevent the armrest part 5 from moving forward.

In the example shown in FIG. 7, the regulating part 12 moves the armrest part 5 further forward than when the rear part of the armrest part 5 is in contact with the backrest part 3 when the backrest part 3 is in the most upright state. The forward movement of the armrest part 5 is restricted so that the armrest part 5 can be moved freely. In the example shown in FIG. 7, even if a foreign object (for example, a person's hand) is caught between the rear part of the armrest part 5 and the backrest part 3 when the backrest part 3 is in the most upright state, the armrest part 5 Since a gap can be secured between the rear part and the backrest part 3, the force applied to the foreign object can be reduced.

In the above-mentioned massage machine 1 and the above-mentioned massage machine 1', the rear part of the armrest part 5 was configured to be able to contact the backing plates 3E and 3F protruding from the frame 3D. , the structure may be such that it can come into contact with a resin molded member provided inside the backrest portion 3 and attached to the frame 3D.

The armrest 5 of the massage machine 1 may be modified, for example, as shown in FIG. 8. FIG. 8 is a side view that shows a schematic diagram of a modified example of the frame of the armrest 5.

In the modification shown in FIG. 8, the armrest 5 includes an upper frame 5A. The upper frame 5A is supported by a support frame 13. The lower surface of the upper frame 5A is attached to the upper surface of the support frame 13 so as to be slidable in the longitudinal direction of the armrest 5 relative to the upper surface of the support frame 13. The support frame 13 is fixed to the base frame 10. In addition, in this modification, unlike the embodiment described above, the acute angle between the longitudinal direction of the armrest 5 and the bottom surface of the base frame 10, that is, the bottom surface of the massage machine 1 when viewed from the side, is at the position of the armrest 5. It remains constant regardless.

In the modification shown in FIG. 8, when providing a restriction part 12 that restricts the forward movement of the armrest part 5, the restriction part 12 may be installed at the front part of the support frame 13 as shown in FIG.

Further, in the above-described embodiments and modifications, an external force is applied to the armrest 5 to separate the armrest 5 and the backrest 3, and the armrest 5 is moved from the state where the armrest 5 and the backrest 3 are separated. When the application of the external force is stopped, the armrest 5 moves rearward due to its own weight, but the present invention is not limited to such a configuration. For example, if an armrest actuator that moves the armrest 5 is provided and no external force is applied to the armrest 5 to separate the armrest 5 and the backrest 3, the rear part of the armrest 5 will move against the backrest 3. The control unit may control the backrest actuator and the armrest actuator so that the armrest 5 comes into contact with them and moves back and forth in conjunction with the reclining motion of the backrest 3. When an external force that separates the armrest 5 and the backrest 3 is applied to the armrest 5, the armrest actuator is configured not to restrict the position of the armrest 5 so that the armrest 5 can be moved by the external force. Just do it.
