Even when the massage massage member 17 is employed, the seat massage mechanism 6 is placed below the backrest portion 3 without causing positional interference with the back massager 40 or the back massage member 38 of the back massage mechanism 8. It can be stored compactly. In other words, the chair-type massage machine 1 of the present invention is a mechanical mechanism that can move the massage portion that can treat the treatment portion to the treatment portion from the buttocks to the thigh, but at a position away from the seat surface. Can be stored compactly, and the manufacturing cost can be kept low.

Next, the shape and arrangement of the seat guide rail 7 which is a feature of the chair type massage machine 1 of the present invention will be described.
As shown in FIG. 2, the seat guide rails 7 on which the rack gears 37 are formed are provided on the left and right sides of the seat frame 4, respectively. The running gear 36 of the seat massage mechanism 6 is engaged. That is, in the seat guide rail 7 described above, the seat massage mechanism 6 is obtained by rotating the travel gear 36 using the rotational driving force generated by the travel motor 34 in a state where the travel gear 36 is engaged with the rack gear 37. Is configured to move in the front-rear direction.

Also, the seat guide rail 7 has a straight rod-like appearance, and is attached in an inclined state so as to descend toward the rear. In the case of the chair type massage machine 1 of the present embodiment, the front end of the seat guide rail 7 is attached to a position slightly lower than the front end of the upper frame member described above, and the rear end of the seat guide rail 7 is The seat part guide rail 7 is attached to a height of about half (about 1/2) in the vertical direction of the seat part frame 4, and the seat part guide rail 7 is inclined at an angle of about 15 ° to 20 ° with respect to the upper frame member. Yes.

When the seat massage mechanism 6 is accommodated using the seat guide rail 7 described above, the seat massage mechanism 6 may be accommodated according to the procedure shown in FIGS.
That is, as shown in FIG. 4, in the state where the traveling gear 36 is located at the front end of the seat guide rail 7, the rotation shaft 19 of the seat massage mechanism 6 is located forward of the traveling gear 36. Therefore, the lower massage massage arm 23 and the lateral massage massage arm 32 attached around the rotation shaft 19 are also arranged so as to protrude upward from the upper frame member. Therefore, when the seat massage mechanism 6 is present at the position shown in FIG. 4, the user's treatment part can be reliably massaged using the lower massage massage arm 23 or the lateral massage massage arm 32.

On the other hand, as shown in FIG. 5, in the state where the traveling gear 36 is rotated and the position of the traveling gear 36 is moved to the midway side in the front-rear direction of the seat guide rail 7, Although it exists in the position higher than a member, the lower massage massage arm 23 comes to exist in the same height as a top frame member, or a slightly higher position. As a result, the lateral massage treatment element 31 provided at the distal end of the lateral massage massage arm 32 is widened while pressing the downward massage treatment element 25 provided at the distal end of the downward massage arm 23 against the treatment part such as the thigh from below. It is possible to perform treatment by pressing from the outside in the direction.

Further, as shown in FIG. 6, in the state where the traveling gear 36 is rotated and the position of the traveling gear 36 is moved to the rear end of the seat guide rail 7, the lower massage massage arm 23 is more than the upper frame member. It will be in a lower position. Moreover, when the thickness of the cushion material is taken into consideration, the lateral massage massage arm 32 comes to be present at a position lower than the seat surface. As a result, the lower heel massager 25 provided at the front end of the lower heel massage arm 23 and the horizontal heel massager 31 provided at the tip of the horizontal massage arm 32 can be accommodated below the seating surface. Thus, the massage mechanism can be stored at a position away from the seating surface (a low position where the user does not feel uncomfortable even when seated).

As described above, if the seat guide rail 7 is arranged in a substantially straight line inclined toward the lower rear side, the seat massage mechanism 6 is moved rearward along the seat guide rail 7 so that the seat massage is performed. The mechanism 6 can be accommodated below the seating surface. Further, if the seat guide rail 7 can be formed in a substantially straight line shape, the manufacturing cost of the parts can be reduced compared with the conventional chair-type massage machine 1 and the chair-type massage can be made. The price of the machine 1 can be reduced.

By the way, as described above, in the chair type massage machine 1 of the present embodiment, the lower massage massage arm 23 of the seat massage mechanism 6 is directed toward the front side and the rear side of the rotation shaft 19 with the rotation shaft 19 as a reference. The structure is such that the tip extends horizontally, and the thickness along the vertical direction can be reduced. If the lower massaging massage arm 23 having a small vertical thickness is employed as described above, the seat massage mechanism 6 is guided to the rear end of the seat guide rail 7 and the back massage mechanism 8 is attached to the lower end of the back guide rail 9. When guided and positioned, the lower massaging massage member 16 of the seat massage mechanism 6 is located further below the back massage mechanism 8 located at the lower end of the back guide rail 9, in other words, further below the back massage member 38. It becomes possible to make it. As a result, it is possible to compactly accommodate the lower massaging massage member 16 in a limited space provided below the back massage mechanism 8.

Further, as shown in FIGS. 7 and 8, the side massage massage member 17 is greatly different from the bottom massage massage arm 23 in the shape of the side massage massage arm 32. That is, the side massage massage arm 32 provided on the side massage massage member 17 is curved so as to swell outward in the width direction from the left and right ends of the base body 14, and is three times as large as the lower massage massage arm 23. It is formed in a shape that rises upward to a certain height. When the side massage massage arm 32 is formed in such a shape that rises upward, the position of the side massage treatment element 31 provided at the tip of the side massage massage arm 32 is made higher than the position of the lower massage treatment element 25. It is possible to perform pressure massage so as to press a treatment part such as a thigh downward from above.

If the side massage massage arm 32 is curved so as to bulge outward in the width direction, the seat massage mechanism 6 is guided to the rear end of the seat guide rail 7 and the back massage mechanism 8 is moved to the back guide rail. When the lower end 9 is guided and positioned, the lateral massaging member 17 of the seat massaging mechanism 6 overlaps with the outer side in the width direction of the back massaging mechanism 8 located at the lower end of the back guide rail 9 in a side view. It is possible to position in an overlapping state (see FIG. 6).

That is, as shown in FIG. 8, in the chair type massage machine 1 of the present embodiment, when the seat massage mechanism 6 is moved to the rear end of the seat guide rail 7, the back treatment element 40 of the back massage mechanism 8 is used. When viewed from the side, since the lateral massage treatment element 31 is positioned outside the back treatment element 40 in the width direction and the lower massage treatment element 25 is located below the back treatment element 40, the lateral massage treatment element 31 and the back treatment The child 40 does not interfere with the position, and the lower heel treatment element 25 and the back treatment element 40 do not interfere with each other.

Therefore, it is possible to move the side massage massage member 17 and the lower massage massage member 16 that are easy to take a space from a seating surface with limited storage space, while being provided with a mechanical massage mechanism that can treat the treatment portion. It can be stored in a distant position.
Further, the side massage massage arm 32 described above extends to the front side and the rear side with respect to the rotation shaft 19 as in the case of the lower massage massage arm 23, and at the tip (upper end) of each massage massage arm 23. A horizontal massage treatment element 31 is formed. These front side and rear side laterality treatment elements 31 are arranged at a distance from each other, and are movable along the seat guide rail 7 while maintaining the same height.

If such a side massage massage member 17 is provided, even if the side massage massage mechanism is moved along the seat guide rail 7, the height and positional relationship of the side massage treatment element 31 do not change. It is possible to perform treatment by lying down on the treatment part up to the thigh and bringing the treatment element 31 into contact with certainty.
“Second Embodiment”
Next, the chair type massage machine 1 of 2nd Embodiment is demonstrated.

As shown in FIG. 10, in the chair type massage machine 1 of the second embodiment, the side massage massage member 17 is divided into two upper and lower members, and the upper end side is attached to be elastically displaceable in the left-right direction with respect to the lower end side. In addition, the horizontal massage member 17 expands or narrows in the left-right direction according to the body shape of the user, so that it is possible to perform good massage for users of various body types.

For example, when a user with a large body is seated on the seat 2, the position of the treatment part such as the thigh is located outside in the left-right direction. In order to correspond to such a treatment part, it is preferable to shift the position of the side massage massage member 17 outward in the left-right direction. However, if the side massage massage member 17 is fixed in the left-right direction, it is difficult to move the side massage massage member 17. However, as shown in the second embodiment, if the horizontal massage member 17 is deformed so as to spread outward in the width direction against the elastic force, the horizontal massage treatment element is also applied to the treatment part located on the outer side in the left-right direction. Since 31 can be reliably pressed, even a large user with a width in the left-right direction can surely treat the treatment portion.

On the other hand, when a user with a small body shape sits on the seat 3, the side massage massage member 17 is elastically applied so that the interval between the side massage treatment elements 31 is narrowed toward the inner side in the width direction. When the position of the treatment part such as is on the inner side in the left-right direction, the side massage massage member 17 naturally moves to the inner side in the left-right direction by the elastic force. Therefore, since the lying treatment element 31 can be reliably pressed against the treatment part such as the user's thigh, the treatment part can be reliably treated even for a user having a small body shape.

Specifically, the horizontal massage member 17 of the second embodiment described above includes a lower massage body 50 disposed on the lower side (drive side), and an upper massage body 51 disposed on the upper portion of the lower massage body 50. The upper massage body 51 is connected to the lower massage body 50 in a swingable manner around an axis (swing shaft 52) facing the front-rear direction and the upper massage body 51 with respect to the lower massage body 50. And an elastic member 54 that urges inward in the direction. Next, the lower massage body 50, the upper massage body 51, the connection part 53, and the elastic member 54 which comprise the side massage massage member 17 of 2nd Embodiment are demonstrated.

The lower massage body 50 is disposed further outward in the width direction of the pair of left and right lower

massage massage members

16 and 16 on the rotary shaft 19 described above. A pair of left and right lower massage bodies 50 are provided as in the first embodiment. These lower massage bodies 50 also convert the rotational driving force of the rotary shaft 19 by the same conversion mechanism as the lower massage massage member 16 (the lateral massage tilt boss member 28, the lateral massage tilt cam surface, and the lateral massage regulation portion 44). By doing so, it is configured to swing along the left-right direction.

The lower massage body 50 is formed in a shape that rises upward to the same height as the lower massage massage arm 23, and the upper end is formed in a shape in which the center side in the front-rear direction protrudes upward. . A through hole 55 that penetrates the lower massage body in the front-rear direction is formed in the portion protruding upward, and a swing shaft 52 is provided so as to penetrate the through hole 55 in the front-rear direction.

The upper massage body 51 is formed in such a shape as to bend from the upper end of the lower massage body 50 so as to swell greatly outward in the width direction and then rise upward to a height of about 3 times that of the lower massage body 23. ing.
Specifically, the upper massage body 51 is a member formed in a substantially V shape in a side view in which the upper part is divided into a fork and a fork. The lower part of the upper massage body 51 is formed in a gate shape in which a midway side in the front-rear direction is recessed in a rectangular shape upward. A communication hole 56 that penetrates the upper massage body 51 in the front-rear direction is formed in the portion formed in the portal shape, and the swing shaft 52 described above communicates the through hole 55 and the communication hole 56. Yes.

The connecting portion 53 has the through hole 55 of the lower massage body 50, the communication hole 56 of the upper massage body 51, and the swing shaft 52 that connects the through hole 55 and the communication hole 56. The swing shaft 52 is disposed so as to face substantially in the front-rear direction, and the upper massage body 51 is connected to the lower massage body 50 so as to be swingable about an axis directed in the front-rear direction.
The elastic member 54 is a member that urges the upper massage body 51 toward the inner side in the width direction with respect to the lower massage body 50, and a coil spring is used in the present embodiment. The coil spring (elastic member 54) is provided between the through hole 55 of the lower massage body 50 and the communication hole 56 of the upper massage body 31, and is provided so as to be wound around the swing shaft 52. Thus, it is possible to generate an urging force (elastic force) in a direction in which the upper massage body 51 is pressed toward the inner side in the width direction with respect to the lower massage body 50.

When the body massage sensor 17 is moved in the front-rear direction while the posture of the lower massage body 50 is fixed, the body-type measurement sensor tilts the upper massage body 51 with respect to the lower massage body 50 (inner width direction or from the width direction). The body shape of the user seated on the seat 2 is determined by measuring the change in the inclination angle toward the outside.
For example, in order to prevent the rotational driving force from being transmitted to the lower massage body 50, in other words, with the rotation of the rotary shaft 19 stopped, the side massage massage member 17 is moved from the front toward the rear using the seat guide rail 7. Let Here, in the state where the seat massage mechanism 6 is located at the front end of the seat guide rail 7, the distance between the lateral massage treatment elements 31 of the left and right lateral massage members 17 is larger than the size of the user in the horizontal direction. Consider the case where is wide. In this case, the upper massage body 51 does not hit the treatment portion, and the upper massage body 51 is most biased inward in the left-right direction due to the elastic force of the elastic member 54.

However, when the seat massage mechanism 6 is further moved to the rear end side of the seat guide rail 7, the size of the user in the left-right direction and the interval between the lateral massage treatment elements 31 of the left and right lateral massage members 17 are eventually equal. Thus, when the upper massage body 51 hits the treatment portion, the upper massage body 51 begins to swing outward in the left-right direction against the elastic force of the elastic member 54. If the swing of the upper massage body 51 is measured by a body shape measurement sensor, the body shape of the user (how much the size in the left-right direction is) can be determined.

In addition, it should be thought that embodiment disclosed this time is an illustration and restrictive at no points. In particular, in the embodiment disclosed this time, matters that are not explicitly disclosed, for example, operating conditions and operating conditions, various parameters, dimensions, weights, volumes, and the like of a component deviate from a range that a person skilled in the art normally performs. Instead, values that can be easily assumed by those skilled in the art are employed.

For example, in the present embodiment, the rack and pinion mechanism is adopted as a specific configuration of the seat guide rail 7, but other moving mechanisms may be used. Similarly, a rack and pinion mechanism may be adopted as a specific configuration of the back guide rail 9, and another moving mechanism such as a shaft mechanism having a feed screw formed on the outer peripheral surface may be used.
Further, with respect to the lower heel treatment element 25 and the side ridge treatment element 31, by swinging the lower heel treatment element 25 and the lateral ridge treatment element 31 in the left-right direction in the same phase, the lower and side portions of the user's buttocks Can be massaged effectively. On the other hand, if the lower heel treatment element 25 and the lateral ridge treatment element 31 are swung in the left-right direction with opposite phases, the treatment portion is massaged so as to be sandwiched between the lower heel treatment element 25 and the horizontal movement treatment element 31. It is also possible.

Further, in the present embodiment, a two-motor type is disclosed that includes a drive motor 18 as a seat massaging drive section and a travel motor 34 for moving the seat massage mechanism 6 back and forth. , 34 can be shared to be a single motor type.
