DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the drawings.
In the massage chair 10 of the present embodiment shown in FIG. 1, the leg portion 11 is placed on the floor surface, and the side walls 12 disposed at both ends in the width direction of the massage chair 10 are supported and fixed to the leg portion 11. ing. Support portions 13 extending upward are fixed to both front and rear end portions of the upper surface of the side wall 12, and an arch-shaped armrest 14 for placing a user's arm, elbow or the like is spanned on the support portion 13. Has been fixed. A seat 15 on which the user can sit is fixed between the left and right side walls 12, and an ottoman 16 for the user to put on a foot is provided at the front lower portion of the seat 15. A backrest portion 17 for allowing a seated user to lean back is provided on the rear portion so as to be tiltable.

  As shown in FIG. 3, in the backrest portion 17, a massage mechanism 19 is incorporated in a main body case 18 made of a hard resin material or the like whose front surface is opened. The body case 18 is provided with a housing space whose front side is open from the lower part to the upper part of the backrest part 17, and a massage mechanism 19 for massaging the user's back is vertically moved along the guide rail 20 in the space. It is assembled so that it can reciprocate in the direction. The massage mechanism 19 includes various drive motors including a motor 21, and the vertical movement of the massage mechanism 19 and the predetermined treatment operation of the pair of treatment elements 19 a provided in the massage mechanism 19 by driving these various drive motors. Is done. The entire body case 18 including the massage mechanism 19 having such a treatment element 19a is covered with a skin material 22 made of leather or the like. Then, the treatment element 19a protrudes forward from the main body case 18 and comes into sliding contact with the inner surface of the skin material 22, and the treatment element 19a stimulates the user through the skin material 22, thereby allowing the user's shoulder and waist Various massages such as itching, rubbing and hitting are applied to each treatment site such as the back.

  On the back surface 17a of the backrest portion 17, a rectangular opening 23 continuously extending in the width direction of the backrest portion 17 is provided above the operation upper end position A of the massaging mechanism 19 in the main body case 18 so as to be transported. A handle recess 24 is formed integrally so that the finger portion can be sufficiently latched. The handle recess 24 is recessed in the direction (front side) perpendicular to the vertical direction of the backrest 17 and is deeper than the massaging mechanism 19 is disposed. In this case, since the handle recess 24 is located above the operation upper end position A of the massage mechanism 19, interference with the massage mechanism 19 is prevented even if it has a deep shape. Further, the recess 24 for the handle has a curved surface shape that slightly swells as the outer side surface of the main body case 18 on the back surface 17a goes downward, so that the lower side 25 of the opening 23 of the recess 24 is on the upper side. The shape protrudes outward from the side 26.

  In addition, a plurality of slit-shaped air holes 27 are provided in the bottom portion (back side surface) of the handle recess 24 side by side in the width direction of the backrest portion 17. The ventilation hole 27 is a hole that communicates the inside and the outside of the backrest portion 17 (main body case 18). The vent hole 27 tends to be messy due to the arrangement of a plurality of holes, and the inside of the backrest portion 17 can be seen through the holes, so that the bottom (back side surface) of the recess 24 for the handle that is inconspicuous from the surrounding people Is aimed at improving the design. By providing such a vent hole 27, heat in the backrest portion 17 generated by the operation of the massage mechanism 19 (motor 21) or the like is discharged to the outside, and the recess 24 for the handle provided with the vent hole 27 is massaged. Since the upper end position A of the mechanism 19 is set above the operation upper end position A, the heat in the backrest portion 17 is effectively discharged from the upper portion where the heat rises.

  In addition, as shown in FIG. 2, a plurality of slit-shaped vent holes 28 are provided in the width direction of the backrest portion 17 in the lower portion of the main body case 18 on the back surface 17 a corresponding to the vent holes 27. ing. The vent hole 28 mainly functions as a suction hole for sucking outside air. By providing the vent hole 28 in a pair with the vent hole 27 described above, discharge of heat from the backrest portion 17 (main body case 23) is further promoted.

  As shown in FIG. 4, the skin material 22 is formed with an opening 22 a in a shape that does not block the opening 23 of the handle recess 24, and is hard at each end of the periphery of the opening 22 a of the skin material 22. A plate-like member 29 made of a resin material is fixed, and the periphery of the opening 22 a and the plate-like member 29 are folded into the bottom side of the handle recess 24. Further, the handle member 30 is inserted into the handle recess 24 so that the peripheral edge of the opening 22 a of the skin material 22 and the plate-like member 29 are sandwiched between the handle recess 24 and the concave handle member 30 that is slightly smaller than the handle recess 24. It is mated. A similar air hole 27 a is formed at the bottom of the handle member 30 so as not to block the plurality of air holes 27 provided at the bottom of the handle recess 24. A flange portion 32 that extends outward is formed on the periphery of the opening 31 of the handle member 30. By pressing the periphery of the opening 22a of the skin material 22 toward the back surface 17a with the flange portion 32, the periphery of the opening 22a where the skin material 22 is likely to float can be pressed. Further, since the skin material 22 can be widely pressed by the flange portion 32, the friction generated between the flange portion 32 and the skin material 22 increases, and the displacement of the skin material 22 can be suppressed.

  Further, as shown in FIG. 5, an annular convex portion 33 is provided at the tip of the flange portion 32, and the annular convex portion 33 bites into the skin material 22, so that the displacement of the skin material 22 is more reliably suppressed. is doing. Further, by fixing the plate-like member 29 to the tip of the peripheral edge of the opening 22a of the skin material 22, even if the skin material 22 expands or contracts somewhat or the skin material 22 is displaced, the plate-like member 29 becomes the recess 24 for the handle. Since it is caught by the handle member 30, it plays a role of retaining. In addition, since the handle member 30 is formed in a shape that follows the recess 24 for the handle, the lower side 34 of the opening 31 of the handle member 30 has a shape that protrudes outward from the upper side 35. Therefore, for example, when the hand is slid from the upper end of the backrest portion 17 toward the lower portion of the back surface 17a, it is easy to collide with the lower side 34 that protrudes outward from the upper side 35. The position is easy to understand.

  In the massage chair 10 configured as described above, the upper portion of the backrest portion 17 that is often carried out at the time of transportation is tilted backward, and the lower portion of the ottoman 16 is raised upward (that is, the ottoman 16, the seat portion 15 and the backrest). In the state in which the portion 17 is linear), the handle member 30 can be placed on the finger without the need for the carrier to be in a low posture, so that it can be easily held and transported easily. Yes.

Next, characteristic effects of the present embodiment will be described.
(1) By providing a handle recess 24 on the back surface 17a of the backrest 17 above the operation upper end position A (see FIG. 3) of the massage mechanism 19 that can hold the finger portion of the hand, When the formed handle member 30 is transported by tilting the upper portion of the backrest portion 17 backward (when transported by two persons), the position of the handle member 30 does not have to be in a low posture, and the finger of the hand is easily hooked. Therefore, it is easy to hold and can be transported easily. Further, the ventilation hole 27 (27a) that communicates the inside and the outside of the backrest portion 17 is formed in the bottom of the recess 24 for the handle and the bottom of the handle member 30, so that the ventilation hole 27 (27a) operates the massage mechanism 19. It is provided above the upper end position A, the heat of the massage mechanism 19 (motor 21) inside the backrest portion 17 rises and is sufficiently discharged from the vent hole 27 (27a), and the heat dissipation efficiency can be improved.

  In addition, a ventilation hole 28 that connects the inside and the outside of the backrest 17 is formed in the lower portion of the back surface 17a of the backrest portion 17, so that the ventilation hole 28 provided at the lower portion of the back surface 17a of the backrest portion 17 mainly serves as outside air. It functions as a suction hole for sucking air and is provided in a pair with the vent hole 27, so that the discharge of heat from the backrest portion 17 can be further promoted.

  (2) The backrest portion 17 is covered with the skin material 22, and the skin material 22 is formed with an opening 22a that does not block the vent hole 27 (27a), so that the finger portion of the hand can be latched. The handle member 30 having a concave portion is fitted into the handle concave portion 24, and the periphery of the opening 22 a of the skin material 22 is sandwiched between the handle member 30 and the handle concave portion 24. Thus, the design of the backrest 17 and thus the entire massage chair 10 can be improved by the skin material 22, and the periphery of the opening 22 a of the skin material 22 is held between the handle member 30 and the handle recess 24. The displacement of the skin material 22 can be suppressed.

  Moreover, the flange part 32 is provided in the opening part 31 periphery of the handle member 30, and the opening part 22a of the skin material 22 presses the back surface 17a side in the flange part 32, The opening part which the skin material 22 tends to float up The periphery of 22a can be pressed down. Further, since the skin material 22 can be widely pressed by the flange portion 32, the friction generated between the flange portion 32 and the skin material 22 increases, and the displacement of the skin material 22 can be suppressed.

  Further, an annular convex portion 33 is formed at the tip of the flange portion 32 of the handle member 30 so as to form a ring around the periphery of the opening 31 of the handle member 30 and protrude from the back surface 17a. Since the opening part 22a of 22 can be pressed down, the shift | offset | difference of the skin material 22 can further be suppressed.

  (3) Following the recess 24 for the handle, the lower side 34 of the opening 31 of the handle member 30 is formed so as to protrude outward from the upper side 35, so that the hand from the upper end of the backrest 17 toward the back surface 17a.
