Summary of the Invention

Problems to be Solved by the Invention

[0004] However, depending on the physique, preferences, etc. of the recipient, the placement position of the recipient's arm corresponding to the reclining operation of the backrest part may not be appropriate. In particular, when the backrest part tilts, when the elbow rest moves backward in conjunction with the backrest part, for example, the elbow rest may move too far to the rear from the position preferred by the recipient.

[0005] In view of the above situation, an object of the present invention is to appropriately adjust the placement position of the arm in the front-rear direction when the backrest part tilts and stands up.

Means for Solving the Problems

[0006] The chair-type massage machine disclosed herein comprises a reclining backrest, armrests, and a frame. The backrest supports the torso of the person being treated. The armrests support the arms of the person being treated. The frame has rails extending in the front-rear direction to support the armrests so that they can slide back and forth. The armrests have a resting portion and a contact portion. The arms of the person being treated are rested on the resting portion. The contact portion contacts the backrest and moves forward together with the resting portion when the backrest is raised from a reclined position. The resting portion is separated from the backrest when the backrest is raised from a reclined position and when the backrest is tilted from an upright position.

[0007] Further features and advantages of the present invention will be further revealed by the embodiments described below. [Effects of the Invention]

[0008] According to the chair-type massage machine disclosed herein, the armrests can be appropriately adjusted in the front-to-back direction when the backrest is tilted and raised. [Brief explanation of the drawing]

[0010] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the drawings.

[0011] <1. First Embodiment> Figure 1 is a schematic perspective view of a chair-type massage machine 1 (hereinafter referred to as "massage machine 1") according to one embodiment. In the following description, the front side (front) as seen from the perspective of a person seated in the massage machine 1 with the backrest 3 not reclined is referred to as the "front side" or "forward side," and the rear side (back) as seen from the perspective of a person seated in the massage machine 1 with the backrest 3 not reclined is referred to as the "rear side" or "backward side." Also, the upper side (head side) as seen from the perspective of a person seated in the massage machine 1 with the backrest 3 not reclined is referred to as the "upper side" or "upward side," and the lower side (leg side) as seen from the perspective of a person seated in the massage machine 1 with the backrest 3 not reclined is referred to as the "lower side" or "downward side." Furthermore, the right side from the perspective of the person receiving treatment while seated in the massage machine 1 is referred to as the "right side" or "rightward direction," and the left side from the perspective of the person receiving treatment while seated in the massage machine 1 is referred to as the "left side" or "leftward direction."

[0012] <1-1. Chair-type massage machine 1> The massage machine 1 comprises a seat 2, a backrest 3, side walls 4, armrests 5, a control panel 6, a cord 7, a stand 8, and an ottoman 9.

[0013] The seat portion 2 supports the buttocks and thighs of the person receiving treatment.

[0014] The backrest portion 3 supports the trunk (such as shoulders, waist, and back) of the subject. The backrest portion 3 is reclinable. That is, the backrest portion 3 is rotatable around a reclining rotation axis (not shown) extending along the left - right direction. The backrest portion 3 incorporates a massage unit (not shown), and guide rails 3B and 3C extending along the surface 3A that contacts the shoulders and waist of the subject. The massage unit is guided by the guide rails 3B and 3C and moves up and down within the backrest portion 3.

[0015] The side wall portions 4 are erected on both the left and right sides of the seat portion 2.

[0016] The elbow rest portions 5 are provided on both the left and right sides of the seat portion 2. The elbow rest portions 5 support the arm (for example, the forearm) of the subject.

[0017] Also, in the present embodiment, the elbow rest portion 5 incorporates an expandable and contractible airbag, and the airbag treats the forearm and hand of the subject. That is, the elbow rest portion 5 includes a treatment portion for treating the forearm and hand of the subject. This treatment portion is, for example, arranged on the placement portion 51 described later. Note that the treatment for the forearm and hand of the subject is not limited to the treatment by the airbag, and any treatment performed using physical means may be used. That is, the treatment performed by the treatment portion provided on the elbow rest portion 5 on the forearm and hand of the subject is not limited to massage on the forearm and hand, and may be, for example, a treatment that applies heat to the forearm and hand, a treatment that applies electrical stimulation to the forearm and hand, etc. Therefore, the elbow rest portion 5 may be configured to include a treatment portion that includes, for example, treatment elements, airbags, vibrators, heaters, electrode pads, etc. alone or in a combination of a plurality.

[0018] Also, not limited to the example of the present embodiment, the elbow rest portion 5 may be configured not to include a treatment portion for treating the forearm and hand of the subject.

[0019] The operation unit 6 is an input device for the treated person to select a treatment pattern, adjust the intensity of the treatment, etc. The operation unit 6 is connected to a control unit (not shown in FIG. 1) provided below the seat part 2 via a cord line 7. The control unit controls each part of the massage machine 1 based on the signal output from the operation unit 6.

[0020] The stand 8 is fixed to the elbow rest part 5 provided on the left side of the seat part 2. The operation unit 6 is detachable from the stand 8.

[0021] The ottoman 9 accommodates the lower leg part of the treated person.

[0022] Further, the massage machine 1 further includes a frame 10. The frame 10 supports the elbow rest part 5 so as to be slidable in the front-rear direction (see FIGS. 2 to 5 described later). For example, at least a part of the frame 10 is accommodated in the side wall part 4.

[0023] The frame 10 has a pair of left and right rail parts 11 (see FIGS. 2 to 5 described later). Each rail part 11 extends in the front-rear direction. The left rail part 11 is arranged on the left side of the seat part 2. The right rail part 11 is arranged on the right side of the seat part 2. Also, each rail part 11 has an upper rail 111 and a lower rail 112. The lower rail 112 is arranged below the upper rail 111. The upper rail 111 and the lower rail 112 each extend in the front-rear direction.

[0024] Further, the frame 10 further has a guide convex part 12. The guide convex part 12 fits into the long hole 531 of the contact part 53 described later and is relatively movable within the long hole 531 (see FIGS. 2 to 5 described later). Note that the guide convex part 12 is an example of the "convex part" of the present invention. Also, in the present embodiment, the guide convex part 12 protrudes from the rail part 11 toward the long hole 531 and protrudes from the upper rail 111 in FIGS. 2 to 5. However, it is not limited to this example, and the guide convex part 12 may protrude from a part of the frame 10 other than the rail part 11.

[0025] <1-2. Elbow rest part 5> Next, an example of the configuration of the armrest 5 will be described with reference to Figures 2 to 5. In the following description, "tilting of the backrest 3" means tilting the backrest 3 backward. Figure 2 is a perspective view from the inside of the left armrest 5 when the backrest 3 is upright in the first embodiment. Figure 3 is a side view from the inside of the left armrest 5 when the backrest 3 is upright in the first embodiment. Figure 4 is a perspective view from the inside of the left armrest 5 when the backrest 3 is tilted in the first embodiment. Figure 5 is a side view from the inside of the left armrest 5 when the backrest 3 is tilted in the first embodiment. Note that in Figures 2 to 5, the exterior covering the surface of the massage machine 1, the cushion part, the side wall part 4, etc. are omitted in order to make the configuration of the main parts easier to see. Also, in Figures 3 and 5, the seat part 2 is also omitted.

[0026] The armrest portion 5 has a mounting portion 51, a sliding portion 52, and a contact portion 53.

[0027] The arm of the person receiving treatment is placed on the resting section 51. For example, in Figures 2 to 5, the part of the armrest 5 that accommodates the arm of the person receiving treatment is the resting section 51. When the backrest 3 is raised from a tilted position and when the backrest 3 is tilted from an upright position, the resting section 51 is separated from the backrest 3. For example, a gap S is formed between the backrest 3 and the resting section 51. The gap S is at least large enough not to trap any part of the person receiving treatment's body. This prevents any part of the person receiving treatment's body (such as the elbow) from getting caught between the backrest 3 and the resting section 51.

[0028] The sliding portion 52 engages with the rail portion 11. The sliding portion 52 is slidable along the rail portion 11 together with the mounting portion 51. In this embodiment, the sliding portion 52 is positioned below the mounting portion 51. The sliding portion 52 has an upper slider 521 and a lower slider 522. The upper slider 521 is fixed to the lower end of the mounting portion 51. The upper slider 521 engages with the upper rail 111 and is slidable in the front-rear direction along the upper rail 111. The lower slider 522 is fixed to the lower end of the upper slider 521. The lower slider 522 engages with the lower rail 112 and is slidable in the front-rear direction along the lower rail 112. As the upper slider 521 moves back and forth on the upper rail 111, the lower slider 522, which is fixed to the upper slider 521, can move back and forth on the lower rail 112.

[0029] The contact portion 53 is positioned below the mounting portion 51 and extends to the rear of the mounting portion 51 at the lower part of the armrest portion 5. In this embodiment, the contact portion 53 is rod-shaped and extends in the front-rear direction.

[0030] For example, when the backrest 3 is tilted upright, the contact portion 53 comes into contact with the backrest 3 and moves forward together with the mounting portion 51. In this way, when the backrest 3 is tilted upright, the contact portion 53 is pushed forward by contact with the backrest 3 and moves together with the mounting portion 51. On the other hand, when the backrest 3 is tilted from an upright position, the shoulders of the person being treated move backward in accordance with the tilt of the backrest 3. As a result, the arms of the person being treated are pulled backward and move backward together with the mounting portion 51. Therefore, the massage machine 1 can appropriately adjust the mounting position of the arms in the front-to-back direction when the backrest 3 is tilted and raised upright.

[0031] The contact portion 53 is movable toward and away from the backrest portion 3. When the backrest portion 3 tilts from an upright position, the contact portion 53 does not move in conjunction with the backrest portion 3, and therefore does not receive a force directed toward the rear from the backrest portion 3, and can be separated from the backrest portion 3 in the front-rear direction (see Figures 4 and 5). However, this example does not exclude a configuration in which contact between the backrest portion 3 and the contact portion 53 is maintained when the backrest portion 3 tilts from an upright position. For example, when the backrest portion 3 tilts from an upright position, as described above, the contact portion 53 also moves toward the rear in accordance with the movement of the patient's arm and the resting portion 51 toward the rear. Therefore, it is possible that the contact portion 53 does not separate from the backrest portion 3 in the front-rear direction.

[0032] In this embodiment, the contact portion 53 is attached to the slide portion 52 and extends to the rear from the upper slider 521 in Figures 2 to 5. This allows the placement position of the patient's arm to be smoothly moved by sliding the slide portion 52 together with the mounting portion 51 along the rail portion 11. However, this example does not exclude configurations in which the contact portion 53 is attached to a member other than the upper slider 521. For example, the contact portion 53 may extend to the rear from the lower slider 522 or the mounting portion 51.

[0033] Furthermore, in this embodiment, the contact portion 53 is positioned below the upper rail 111 and does not engage with the rail portion 11. However, the example provided in this embodiment is not limited to the contact portion 53, and the contact portion 53 may engage with the rail portion 11 (for example, the upper rail 111 or the lower rail 112) and may be slidable in the front-rear direction along the rail portion 11. In this way, the contact portion 53 can move smoothly in the front-rear direction.

[0034] The contact portion 53 has an elongated hole 531 that extends in the front-rear direction. For example, the elongated hole 531 penetrates the contact portion 53 in the left-right direction. When the contact portion 53 moves in the front-rear direction, the contact portion 53 is guided in the front-rear direction by a guide projection 12 that moves relative to it within the elongated hole 531. As the contact portion 53 moves, the guide projection 12 is guided within the elongated hole 531, allowing the massage machine 1 to move the placement position of the person being treated more smoothly. Furthermore, when the guide projection 12 reaches the rear end of the elongated hole 531, the contact portion 53 cannot move forward, and when the guide projection 12 reaches the front end of the elongated hole 531, it cannot move backward. Therefore, the massage machine 1 can restrict the range of movement of the placement position of the person being treated according to the width of the elongated hole 531 in the front-rear direction.

[0035] In Figures 2 to 5, the mounting portion 51, the sliding portion 52, and the contact portion 53 are shown as separate parts. However, the model is not limited to this example, and some of these parts may be integrated with other parts. Alternatively, all of them may be integrated. For example, in the second embodiment described later, an example is shown in which the mounting portion 51 is integrated with the contact portion 53.

[0036] Preferably, as shown in Figures 2 to 5, the armrest portion 5 further comprises a covering portion 54. The covering portion 54 covers the rear end of the contact portion 53. In this way, the rear end of the contact portion 53 that can come into contact with the backrest portion 3 can be protected by the covering portion 54. Therefore, when the backrest portion 3 is raised, it is possible to prevent the contact portion 53 from coming into contact with the backrest portion 3 with a strong impact.

[0037] More preferably, the covering portion 54 is made of a soft material such as resin. For example, the soft material includes polymer compounds such as synthetic resins, as well as soft materials in general that can prevent wear and noise generation due to the contact portion against the backrest. When the backrest portion 3 tilts and stands up, the contact portion 53 slides vertically against the surface of the backrest portion 3 while in contact with the backrest portion 3. Therefore, by having the contact portion 53 come into contact with the backrest portion 3 via the covering portion 54 made of a soft material, wear and noise generation associated with sliding can be prevented.

[0038] The above examples do not exclude configurations in which the rear end of the contact portion 53 is not covered by the covering portion 54. For example, the covering portion 54 may be omitted. Alternatively, instead of the covering portion 54, a roller capable of rolling on the surface of the backrest portion 3 may be placed at the rear end of the contact portion 53.

[0039] Preferably, as shown in Figures 2 to 5, the backrest portion 3 further has a recess 31. The recess 31 is located at the lower end of the backrest portion 3 and is recessed from the front side to the back side of the backrest portion 3. The recess 31 can accommodate the rear end of the contact portion 53 and the covering portion 54. For example, when the backrest portion 3 is raised from a tilted position, the contact portion 53 comes into contact with the bottom surface of the recess 31. This makes it difficult for a part of the patient's body to enter between the backrest portion 3 and the contact portion 53. Therefore, it is possible to prevent a part of the patient's body from getting caught between the backrest portion 3 and the contact portion 53. Note that this example does not exclude configurations in which the recess 31 is omitted.

[0040] Preferably, as shown in Figures 2 to 5, the mounting portion 51 has a cover portion 511 that covers the upper side of the contact portion 53. The cover portion 511 is positioned above the contact portion 53 and extends rearward at the rear end of the mounting portion 51. The rear end of the cover portion 511 is separated in front of the backrest portion 3 by a gap that does not pinch any part of the body of the person being treated. For example, as shown in Figures 2 and 3, when the backrest portion 3 is upright, the upper end of the recess 31 and the cover portion 511 are separated in the front-rear direction and face each other.

[0041] This configuration makes it even more difficult for any part of the patient's body to enter between the backrest 3 and the contact portion 53 due to the cover portion 511. Furthermore, when the backrest 3 is in an upright position, the upper end of the recess 31 and the cover portion 511 are separated and facing each other in the front-rear direction, thus preventing any part of the patient's body from getting caught between the backrest 3 and the cover portion 511. Therefore, it is possible to more effectively prevent the patient's body from getting caught between the backrest 3 and the armrest 5. However, this example does not exclude configurations in which the cover portion 511 is omitted.

[0042] <3. Second Embodiment> Next, the second embodiment will be described with reference to Figures 6 and 7. Figure 6 is a side view of the left armrest 5 as seen from the inside, with the backrest 3 in an upright position, in the second embodiment. Figure 7 is a side view of the left armrest 5 as seen from the inside, with the backrest 3 in a tilted position, in the second embodiment. In the following, the configuration of the second embodiment will be described in a manner different from that of the first embodiment. Also, the same reference numerals will be used for components similar to those in the first embodiment, and their descriptions may be omitted.

[0043] In the second embodiment, the armrest portion 5 has a contact portion 53a instead of the rod-shaped contact portion 53 in the first embodiment. The contact portion 53a protrudes to the rear from the rear end of the mounting portion 51. This allows the contact portion 53a to be positioned with a simple configuration.

[0044] The tip of the contact portion 53a is a detachable portion from the backrest portion 3 and has a rounded shape. This configuration allows the contact portion 53a to move smoothly across the surface of the backrest portion 3 when it comes into contact with and separates from the backrest portion 3.

[0045] The cover portion 511 covers the upper side of the contact portion 53a, and in Figures 6 and 7, for example, it covers the upper side of a part of the contact portion 53a (for example, the front end of the contact portion 53a that is connected to the rear end of the mounting portion 51).

[0046] Furthermore, at least a portion of the contact portion 53a may protrude to the rear from the cover portion 511. However, this example does not exclude a configuration in which the contact portion 53a protrudes to the rear from a portion of the rear end of the mounting portion 51 other than the cover portion 511.

[0047] In the second embodiment, for example, when the backrest 3 is raised from a tilted position, as shown in Figure 6, the contact portion 53a comes into contact with the backrest 3 (for example, the bottom surface of the recess 31) and moves forward together with the resting portion 51. In this way, when the backrest 3 is raised from a tilted position, the contact portion 53a is pushed forward by contact with the backrest 3 and moves together with the resting portion 51. On the other hand, when the backrest 3 is tilted from an upright position, the shoulders of the person being treated move backward in accordance with the tilt of the backrest 3. As a result, the arms of the person being treated are pulled backward and move backward together with the resting portion 51. Therefore, the massage machine 1 can appropriately adjust the resting position of the arms in the front-rear direction when the backrest 3 is tilted and raised.

[0048] The contact portion 53a is capable of moving toward and away from the backrest portion 3. When the backrest portion 3 tilts from an upright position, the contact portion 53a does not move in conjunction with the backrest portion 3. Therefore, as shown in Figure 7, it does not receive a force directed toward the rear from the backrest portion 3 and can be separated from the backrest portion 3 in the front-rear direction. However, this example does not exclude a configuration in which contact between the backrest portion 3 and the contact portion 53a is maintained when the backrest portion 3 tilts from an upright position. For example, when the backrest portion 3 tilts from an upright position, as described above, the contact portion 53a also moves toward the rear in accordance with the movement of the patient's arm and the resting portion 51 toward the rear. Therefore, it is possible that the contact portion 53a does not separate from the backrest portion 3 in the front-rear direction.

[0049] Preferably, as shown in Figures 6 and 7, the armrest portion 5 further comprises a covering portion 54a. The covering portion 54a covers the rear end of the contact portion 53a. In this way, the rear end of the contact portion 53a that can come into contact with the backrest portion 3 can be protected by the covering portion 54a. Therefore, when the backrest portion 3 is raised, it is possible to prevent the contact portion 53a from coming into contact with the backrest portion 3 with a strong impact.

[0050] More preferably, the covering portion 54a is made of a soft material such as resin, similar to the covering portion 54 in the first embodiment. This example does not exclude a configuration in which the rear end of the contact portion 53a is not covered by the covering portion 54a.

[0051] <4. Remarks> The embodiments described above should be considered illustrative and not restrictive in all respects, and the technical scope of the present invention is indicated by the claims rather than by the description of the embodiments described above, and should be understood to include all modifications that fall within the meaning and scope equivalent to the claims.

[0052] <5.
