< 1> first embodiment

Fig. 1 is a schematic perspective view of a seat-type massage machine 1 (hereinafter, referred to as "massage machine 1") according to an embodiment. In the following description, a front side (front side) when viewed from a person to be treated who sits on the massage machine 1 in a state in which the backrest 3 is not laid down is referred to as a "front side" or a "front", and a rear side (rear side) when viewed from a person to be treated who sits on the massage machine 1 in a state in which the backrest 3 is not laid down is referred to as a "rear side" or a "rear". The upper side (head side) of the massage machine 1 when viewed from the user sitting on the non-reclined back rest 3 is referred to as "upper side" or "upper side", and the lower side (foot side) of the massage machine 1 when viewed from the user sitting on the non-reclined back rest 3 is referred to as "lower side" or "lower side". The right side when viewed from the person sitting on the massage machine 1 is referred to as "right side" or "right side", and the left side when viewed from the person sitting on the massage machine 1 is referred to as "left side" or "left side".

<1-1. Chair-type massage machine 1>

The massage machine 1 includes a seat 2, a backrest 3, a side wall 4, a armrest 5, an operation unit 6, a cable 7, a bracket 8, and a leg rest 9.

The seat 2 supports the buttocks and thighs of the person to be treated.

The backrest 3 supports the trunk (shoulder, waist, back, etc.) of the person to be treated. The backrest part 3 can lie down. That is, the backrest 3 is rotatable about a reclining rotation axis (not shown) extending in the left-right direction. The backrest portion 3 incorporates a massage unit (not shown) and guide rails 3B and 3C extending along a surface 3A that contacts the shoulder and waist of the person to be treated. The massage unit is guided by the guide rails 3B and 3C to be lifted and lowered in the backrest portion 3.

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

The armrest portions 5 are provided on the left and right sides of the seat portion 2. The armrest portion 5 supports an arm (e.g., forearm) of a person to be treated.

In the present embodiment, an inflatable and contractible air bag is incorporated in the armrest 5, and the forearm and the hand of the person to be treated are treated with the air bag. That is, the armrest portion 5 includes a treatment portion for performing treatment on the forearm and the hand of the person to be treated. The treatment unit is disposed on a placement unit 51 described later, for example. The treatment of the forearm and the hand of the person to be treated is not limited to the treatment by the balloon, and may be performed by physical means. That is, the treatment performed by the treatment unit provided in the armrest 5 on the forearm and the hand of the person to be treated is not limited to the massage on the forearm and the hand, and may be, for example, the treatment of applying heat to the forearm and the hand, the treatment of applying electrical stimulation to the forearm and the hand, or the like. Therefore, the armrest portion 5 may be configured to include a treatment portion including, for example, a treatment member, an air bag, a vibrator, a heater, an electrode pad, or the like, alone or in combination of a plurality of treatment portions.

The present utility model is not limited to the example of the present embodiment, and the armrest portion 5 may be configured not to include a treatment portion for performing treatment on the forearm and the hand of the person to be treated.

The operation unit 6 is an input device for the person to be treated to select a treatment mode, adjust the intensity of treatment, and the like. The operation unit 6 is connected to a control unit (not shown in fig. 1) provided below the seat 2 via a cable 7. The control unit controls each part of the massage machine 1 based on the signal output from the operation unit 6.

The bracket 8 is fixed to the armrest portion 5 provided on the left side of the seat portion 2. The operation unit 6 is detachable from the holder 8.

The leg rest 9 accommodates the lower leg of the person to be treated.

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

The frame 10 has a pair of right and left rail portions 11 (see fig. 2 to 5 described later). Each rail portion 11 extends in the front-rear direction. The left rail portion 11 is disposed on the left side of the seat portion 2. The right rail portion 11 is disposed on the right side of the seat portion 2. Each rail portion 11 has an upper rail 111 and a lower rail 112. The lower rail 112 is disposed below the upper rail 111. The upper rail 111 and the lower rail 112 extend in the front-rear direction, respectively.

In addition, the frame 10 also has a guide projection 12. The guide projection 12 is fitted into a long hole 531 of the abutment portion 53 described later, and is movable relatively in the long hole 531 (see fig. 2 to 5 described later). The guide convex portion 12 is an example of the "convex portion" of the present utility model. The guide projection 12 protrudes from the rail portion 11 toward the long hole 531 in the present embodiment, and protrudes from the upper rail 111 in fig. 2 to 5. However, the present utility model is not limited to this example, and the guide projection 12 may protrude from a portion other than the rail portion 11 of the frame 10.

<1-2. Armrest portion 5>

Next, a structural example of the armrest portion 5 will be described with reference to fig. 2 to 5. In the following description, tilting of the backrest 3 means tilting the backrest 3 backward. Fig. 2 is a perspective view of the left armrest portion 5 in the state in which the backrest portion 3 is raised as viewed from the inside in the first embodiment. Fig. 3 is a side view of the left armrest portion 5 in the state in which the backrest portion 3 is erected as viewed from the inside in the first embodiment. Fig. 4 is a perspective view of the left armrest portion 5 in a state where the backrest portion 3 is tilted when viewed from the inside in the first embodiment. Fig. 5 is a side view of the left armrest portion 5 in a state where the backrest portion 3 is tilted when viewed from the inside in the first embodiment. In fig. 2 to 5, the outer cover covering the surface of the massage machine 1, the pad portion, the side wall portion 4, and the like are omitted for the sake of easy observation of the structure of the main portion. In fig. 3 and 5, illustration of the seat 2 is omitted.

The armrest 5 includes a mounting portion 51, a sliding portion 52, and an abutment portion 53.

The arm of the person to be treated is placed on the placement unit 51. For example, in fig. 2 to 5, a portion of the armrest portion 5 that accommodates the arm of the person to be treated is a placement portion 51. The placement portion 51 is separated from the backrest portion 3 when the backrest portion 3 is raised from the tilted state and when the backrest portion 3 is tilted from the raised state. For example, a gap S is formed between the backrest portion 3 and the placement portion 51. The gap S has a space of at least a degree that does not clamp a part of the body of the person to be treated. In this way, a part of the body (for example, an elbow) of the person to be treated can be prevented from being sandwiched between the backrest portion 3 and the placement portion 51.

The slide portion 52 engages with the rail portion 11. The slide portion 52 is slidable along the rail portion 11 together with the placement portion 51. In the present embodiment, the slide portion 52 is disposed below the placement portion 51. The slider 52 has an upper slider 521 and a lower slider 522. The upper slider 521 is fixed to the lower end portion of the mounting portion 51. The upper slider 521 is engaged with the upper rail 111, and the upper slider 521 is slidable in the front-rear direction along the upper rail 111. The lower slider 522 is fixed to the lower end portion of the upper slider 521. The lower slider 522 is engaged with the lower rail 112, and the lower slider 522 is slidable in the front-rear direction along the lower rail 112. The lower slider 522 fixed to the upper slider 521 can move back and forth on the lower rail 112 as the upper slider 521 moves back and forth on the upper rail 111.

The abutment portion 53 is disposed below the placement portion 51, and extends to the rear side of the placement portion 51 at the lower portion of the armrest portion 5. In the present embodiment, the abutting portion 53 is in the shape of a rod extending in the front-rear direction.

For example, when the backrest portion 3 is raised from the tilted state, the abutment portion 53 abuts against the backrest portion 3 and moves forward together with the placement portion 51. Thus, when the backrest 3 is raised from the tilted state, the abutment portion 53 is pushed forward by the abutment with the backrest 3, and moves together with the mounting portion 51. On the other hand, when the backrest 3 is tilted from the raised state, the shoulder of the person to be treated moves rearward in accordance with the tilting of the backrest 3. Therefore, the arm of the person to be treated is pulled rearward, and moves rearward together with the placement portion 51. Therefore, the placement position of the arm in the front-rear direction of the massage machine 1 can be appropriately adjusted when the backrest 3 is tilted and raised.

The contact portion 53 can be brought into contact with and separated from the backrest portion 3. When the backrest 3 is tilted from the raised state, the abutment portion 53 is not interlocked with the backrest 3, and therefore can be separated from the backrest 3 in the front-rear direction without receiving a force directed to the rear side from the backrest 3 (see fig. 4 and 5). However, this example does not exclude a configuration that maintains contact between the backrest portion 3 and the abutment portion 53 when the backrest portion 3 is tilted from the raised state. For example, when the backrest 3 is tilted from the raised state, the abutment portion 53 moves rearward in response to the movement of the arm and the placement portion 51 of the person to be treated rearward as described above. Therefore, the abutment portion 53 can be prevented from being separated from the backrest portion 3 in the front-rear direction.

The abutment portion 53 is attached to the slide portion 52 in the present embodiment, and extends rearward from the upper slider 521 in fig. 2 to 5. Thus, the sliding portion 52 slides along the rail portion 11 together with the placement portion 51, and the placement position of the arm of the person to be treated can be smoothly moved. However, this illustration does not exclude a structure in which the abutting portion 53 is attached to a member other than the upper slider 521. For example, the abutting portion 53 may extend rearward from the lower slider 522 or the mounting portion 51.

In the present embodiment, the abutting portion 53 is disposed below the upper rail 111, and does not engage with the rail portion 11. However, the contact portion 53 is not limited to the example of the present embodiment, and may be engaged with the rail portion 11 (for example, the upper rail 111 or the lower rail 112), or may be slidable in the front-rear direction along the rail portion 11. In this way, the abutment portion 53 can smoothly move in the front-rear direction.

The abutment portion 53 has a long hole 531 extending in the front-rear direction. For example, the long hole 531 penetrates the abutment portion 53 in the left-right direction. When the abutting portion 53 moves in the front-rear direction, the abutting portion 53 is guided in the front-rear direction by the guide convex portion 12 relatively moving in the long hole 531. When the contact portion 53 moves, the guide projection 12 is guided in the long hole 531, and the massage machine 1 can move the placement position of the arm of the person to be treated more smoothly. Further, the abutment portion 53 cannot move forward when the guide projection 12 reaches the rear end portion of the long hole 531, and the abutment portion 53 cannot move rearward when the guide projection 12 reaches the front end portion of the long hole 531. Therefore, the massager 1 can limit the movement range of the placement position of the arm of the person to be treated according to the width of the long hole 531 in the front-rear direction.

In fig. 2 to 5, the placement portion 51, the sliding portion 52, and the contact portion 53 are separate members. However, the present utility model is not limited to this example, and some of them may be integrated with other parts. Alternatively, all of them may be integrated. For example, in a second embodiment described later, an example is shown in which the mounting portion 51 and the abutment portion 53 are integrated.

As shown in fig. 2 to 5, the armrest portion 5 is preferably further provided with a cover portion 54. The covering portion 54 covers the rear end portion of the abutting portion 53. In this way, the rear end portion of the contact portion 53 that can contact the backrest portion 3 can be protected by the cover portion 54. Therefore, the abutting portion 53 can be prevented from abutting against the backrest portion 3 with a strong impact when the backrest portion 3 is raised.

More preferably, the cover 54 is made of a soft material such as a resin. For example, the soft material includes not only a polymer compound represented by a synthetic resin but also all soft materials capable of preventing abrasion and noise from occurring due to contact of the contact portion with the backrest. When the backrest 3 is tilted and raised, the contact portion 53 slides in the up-down direction with respect to the surface of the backrest 3 while being in contact with the backrest 3. Therefore, the contact portion 53 contacts the backrest portion 3 via the cover portion 54 made of a soft material, and abrasion, noise, and the like due to sliding can be prevented.

The above-described example does not exclude a configuration in which the rear end portion of the contact portion 53 is not covered by the covering portion 54. For example, the cover 54 may be omitted. Alternatively, a roller capable of rolling on the surface of the backrest 3 may be disposed at the rear end of the contact portion 53 instead of the cover portion 54.

As shown in fig. 2 to 5, the backrest 3 preferably further has a concave portion 31. The recess 31 is disposed at the lower end of the backrest portion 3, and is recessed from the front surface side toward the rear surface side of the backrest portion 3. The recess 31 can accommodate the rear end portion of the abutment portion 53 and the cover portion 54. For example, when the backrest portion 3 is raised from the tilted state, the contact portion 53 contacts the bottom surface of the recess 31. Thus, a part of the body of the person to be treated is less likely to enter between the backrest part 3 and the abutment part 53. Therefore, it is possible to suppress a part of the body of the person to be treated from being pinched between the backrest portion 3 and the abutment portion 53. Note that this example does not exclude the structure in which the concave portion 31 is omitted.

As shown in fig. 2 to 5, the placement portion 51 preferably includes a cover portion 511 that covers the upper side of the contact portion 53. The cover 511 is disposed above the contact portion 53 and extends rearward at the rear end of the placement portion 51. The rear end portion of the cover 511 is separated forward from the backrest portion 3 by a distance that does not sandwich a part of the body of the person to be treated. For example, as shown in fig. 2 and 3, in a state where the backrest portion 3 is raised, the upper end of the concave portion 31 is separated from and opposed to the cover portion 511 in the front-rear direction.

Thus, by the cover portion 511, a part of the body of the person to be treated is less likely to enter between the backrest portion 3 and the abutment portion 53. Further, since the upper end of the concave portion 31 and the cover portion 511 are separated and opposed to each other in the front-rear direction in the state where the backrest portion 3 is raised, it is also possible to prevent a part of the body of the person to be treated from being sandwiched between the backrest portion 3 and the cover portion 511. Therefore, the body of the person to be treated can be more effectively prevented from being pinched between the backrest portion 3 and the armrest portion 5. However, this example does not exclude the structure in which the cover 511 is omitted.

<2 > second embodiment

Next, a second embodiment will be described with reference to fig. 6 and 7. Fig. 6 is a side view of the left armrest portion 5 in a state where the backrest portion 3 is erected as viewed from the inside in the second embodiment. Fig. 7 is a side view of the left armrest portion 5 in a state where the backrest portion 3 is tilted when viewed from the inside in the second embodiment. The following describes a second embodiment, which is different from the first embodiment. In addition, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof may be omitted.

In the second embodiment, the armrest portion 5 has an abutment portion 53a instead of the rod-shaped abutment portion 53 in the first embodiment. The abutment portion 53a protrudes rearward from the rear end portion of the placement portion 51. In this way, the abutting portion 53a can be arranged with a simple configuration.

The tip end portion of the abutting portion 53a is separable from the backrest portion 3, and has a rounded shape. With this configuration, the contact portion 53a can smoothly move on the surface of the backrest portion 3 when being brought into contact with and separated from the backrest portion 3.

The cover 511 covers the upper side of the contact portion 53a, and covers the upper side of a part of the contact portion 53a (for example, the front end portion of the contact portion 53a connected to the rear end portion of the mounting portion 51 or the like) in fig. 6 and 7.

At least a part of the contact portion 53a may protrude rearward from the cover portion 511. However, this example does not exclude a configuration in which the contact portion 53a protrudes rearward from a portion other than the cover portion 511 at the rear end portion of the mounting portion 51.

In the second embodiment, for example, when the backrest portion 3 is raised from the tilted state, as shown in fig. 6, the abutment portion 53a abuts against the backrest portion 3 (for example, the bottom surface of the recess 31) and moves forward together with the placement portion 51. Thus, when the backrest 3 is raised from the tilted state, the abutment portion 53a is pushed forward by the abutment with the backrest 3, and moves together with the mounting portion 51. On the other hand, when the backrest 3 is tilted from the raised state, the shoulder of the person to be treated moves rearward in accordance with the tilting of the backrest 3. Therefore, the arm of the person to be treated is pulled backward, and moves backward together with the placement portion 51. Therefore, the massage machine 1 can appropriately adjust the placement position of the arm in the front-rear direction when the backrest 3 is tilted and raised.

The contact portion 53a can be brought into contact with and separated from the backrest portion 3. When the backrest 3 is tilted from the raised state, the abutment portion 53a does not interlock with the backrest 3. Therefore, as shown in fig. 7, the abutment portion 53a can be separated from the backrest portion 3 in the front-rear direction without receiving a force directed to the rear side from the backrest portion 3. However, this example does not exclude a configuration that maintains contact between the backrest portion 3 and the abutment portion 53a when the backrest portion 3 is tilted from the raised state. For example, when the backrest 3 is tilted from the raised state, the abutment portion 53a moves rearward in response to the movement of the arm and the placement portion 51 of the person to be treated rearward as described above. Therefore, the abutting portion 53a can be prevented from being separated from the backrest portion 3 in the front-rear direction.

Preferably, the armrest portion 5 further includes a cover portion 54a, as shown in fig. 6 and 7. The covering portion 54a covers the rear end portion of the abutting portion 53a. In this way, the rear end portion of the contact portion 53a that can contact the backrest portion 3 can be protected by the cover portion 54a. Therefore, the abutting portion 53a can be prevented from abutting against the backrest portion 3 with a strong impact when the backrest portion 3 is raised.

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