An embodiment of the present invention will be described below with reference to the drawings.
The mattress type massage apparatus shown in FIG. 1 includes a rectangular flat base 1. The base body 1 is formed of a bendable sheet-like synthetic resin, and can be folded in half from the middle in the longitudinal direction.

  The base body 1 may be configured, for example, by laminating a single synthetic resin sheet or a plurality of synthetic resin sheets having different hardness and strength. Furthermore, the substrate 1 is not limited to one or a plurality of laminated synthetic resin sheets, and may be a skeleton structure or the like, and the structure or form is not limited at all.

  A pair of guide rails 4 formed of synthetic resin such as nylon (trade name) or polypropylene are laid in parallel on the both ends of the upper surface of the base 1 in parallel with each other. As shown in FIG. 3, the guide rail 4 has a belt-like base portion 4a, and L-shaped support portions 4b are formed at both ends of the base portion 4a in the width direction. A pair of L-shaped pieces 4c project from the upper and lower surfaces of the middle portion of the base portion 4a so as to face each other. Thereby, passages 4d are formed on the upper and lower surfaces of the base portion 4a, respectively, and the side of the upper passage 4d is a running surface 4e of a wheel 27 described later.

  The guide rail 4 is slidably held on the upper surface of the base 1 by a plurality of holders 4f (only one is shown in FIG. 3). That is, the holder 4f is formed in a substantially U shape as shown in FIG. 3, the midway portion is positioned on the lower surface of the base 1, and the engaging portions 4g on both sides bent in an L shape are connected to the base. 1 is protruded from the pair of through holes 1 a formed on the upper surface side of the base 1 and engaged with the support portion 4 b of the guide rail 4. Accordingly, the guide rail 4 is slidably held on the base body 1.

  As shown in FIG. 1, a plurality of slits 5 are formed at predetermined intervals in the central portion of the guide rail 4 in the longitudinal direction, except for the base portion 4 a of the guide rail 4. Therefore, the guide rail 4 can be bent together with the base 1 from the slit 5 portion.

  As shown in FIG. 2, a base 6 having a triangular side surface is provided at one longitudinal end of the base 1. The gantry 6 supports one end of the guide rail 4 in the longitudinal direction so as to be gradually inclined higher toward the end.

  A driving device 10 is provided on the upper surface of the other end of the base 1 in the longitudinal direction, that is, on the other end of the guide rail 4. This drive device 10 has a case 11 as shown in FIGS. A drive source 12 in which a speed reducer and a motor are integrated is provided in the case 11. The drive source 12 is configured to rotationally drive a pair of meshed gears 13 provided on both sides of the case 11 in opposite directions. Each gear 13 is integrally provided with a drive pulley 14.

  As shown in FIG. 2, both ends of a belt 15 as a power transmission strip made of a metal strip such as stainless steel are wound around each pair of drive pulleys 14. 2, the middle portion of the belt 15 is inserted into the upper and lower passages 4d of the guide rail 4 as shown in FIG. 2, and the middle portion is a frame 6 that supports one end of the guide rail 4 as shown in FIG. Is supported by a roller 16 rotatably provided by a support shaft 16a.

  When the drive source 12 is activated and each pair of gears 13 is driven in the opposite direction, the belt 15 is fed out from the drive pulley 14 of one gear 13 and wound around the drive pulley 14 of the other gear 13. . Thereby, the belt 15 is driven to travel along the passage 4d.

  For example, in FIG. 2, when one drive pulley 14 is rotated in the arrow X direction and the other drive pulley 14 is rotated in the Y direction, the portion passed through the upper passage 4d of the belt 15 travels in the direction indicated by the arrow Z. It is designed to be driven.

  As shown in FIG. 1, a traveling range detection mechanism 17 that reciprocates the belt 15 within a certain traveling range is provided in the case 11. Although not shown in detail, the travel range detection mechanism 17 detects, for example, the travel distance of the belt 15 based on the number of rotations of the drive pulley 14 and converts the rotation direction of the gear 13 by the drive source 12 based on the detection signal. As a result, the belt 15 can be reciprocated within a certain traveling range.

  A first holding body 21a and a second holding body 21b are provided between the pair of guide rails 4 as shown in FIG. Each holding body 21a, 21b is provided with a hollow support shaft 22 as shown in FIG. Both ends of the support shaft 22 are detachably fitted in attachment holes 24 formed in the support 23. A screw shaft 25 is inserted through the support shaft 22. Both ends of the screw shaft 25 protrude to the outer surface side of the support 23, and a nut 26 is screwed there.

  The above-described pair of wheels 27 (shown in FIG. 6) are rotatably provided on both sides of the lower end of the support 23 by a support shaft 27a. The wheel 27 travels on the guide surface 4e of the guide rail 4 as described above.

  As shown in FIG. 6, both ends of the wire 30 are fixed to the upper outer surface of the support 23 by screws 31. A midway portion of the wire 30 is connected and fixed to a pair of attachment members 34 fixed to the upper surface of the belt 15. As a result, the wire 30 causes the holders 21 a and 21 b to be interlocked with the travel of the belt 15 via the attachment member 34. That is, each holding body 21a, 21b is driven to reciprocate in a range from a position indicated by a solid line to a position indicated by a chain line in FIG.

  As shown in FIGS. 1 and 3, four main massage rollers 35 are rotatably held on a support shaft 22 of the holding bodies 21 a and 21 b through a collar 36. A plurality of hemispherical protrusions 35 a are provided on the outer peripheral surface of each massage roller 35 at predetermined intervals in the circumferential direction.

  As shown in FIGS. 1 and 2, a tension adjusting mechanism 38 that controls the tension of the belt 15 is provided at one end portion of the pair of guide rails 4 located on the drive device 10 side. Although not shown in detail, the tension adjusting mechanism 38 includes a spring 39 that is compressed by the tension of the belt 15 applied in the direction indicated by the arrow A in FIG.

  When slack is generated due to the belt 15 extending, the tension adjusting mechanism 38 slides the guide rail 4 in the direction opposite to the arrow A by the restoring force of the spring 39. Thereby, the slack produced in the belt 15 can be removed.

  A band plate-like attachment member 41 is provided along the width direction on a portion of the upper surface of one end in the longitudinal direction of the base body 1 that is curved and supported upward by the gantry 6 of the guide rail 4. The attachment member 41 is fixed to the base 1, and one end of a swing arm 42 is pivotally attached to each end in the longitudinal direction by a pin 43.

  An L-shaped bent portion 44 is formed at the other end of the swing arm 42 as shown in FIG. 10, and one end of a screw shaft 45 is connected to a nut 46 at one side of the bent portion 44 as shown in FIG. It is fixed by.

  The screw shaft 45 is provided with a pair of thin spacers 47b with a thick spacer 47a interposed therebetween. These spacers 47a and 47b are held incapable of being pulled out by a cap nut 48 screwed into the other end of the screw shaft 45. A pair of thin spacers 47b is rotatably mounted with a resin holder 49. Each holder 49 holds a shoulder massage roller 51. That is, two shoulder massage rollers 51 are provided on one swing arm 42.

  As shown in FIG. 4, one end pivotally attached to the mounting member 41 of each swing arm 42 is located outside the pair of guide rails 4 and the other end provided with the shoulder massage roller 51 is located inside. positioned.

  The pair of swing arms 42 configured as described above are driven to swing by a swing drive mechanism 53 with one end pivotally attached to the mounting member 41 by a pin 43 as a fulcrum. The swing drive mechanism 53 has a power transmission shaft 54 as shown in FIGS. The power transmission shaft 54 is divided into a drive shaft portion 54a and a driven shaft portion 54b. The rotation of the drive shaft portion 54a is transmitted to the driven shaft portion 54b by a joint mechanism 55 as will be described later.

  As shown in FIG. 8, the joint mechanism 55 includes a transmission pin 56 projecting from the outer peripheral surface of one end of the drive shaft portion 54a and one end of a cylindrical member as a semi-cylindrical portion 57a, and the remaining cylindrical portions. And a transmission member 57 provided by being fitted and fixed to one end of the driven shaft portion 54b.

  One end portion of the drive shaft portion 54 a is inserted into the cylindrical portion of the transmission member 57. Accordingly, when the drive shaft 54a rotates, the transmission pin 56 comes into contact with the end surface of the semi-cylindrical portion 57a to transmit the rotation of the drive shaft portion 54a to the driven shaft portion 54b.

  Midway portions of the drive shaft portion 54a and the driven shaft portion 54b whose one end portions are connected by the joint mechanism 55 are rotatably supported by bearings 58, respectively, and a disk 59 is attached to the other end portion. .

  A connecting hole 61 is formed at an eccentric position of each disk 59. Each connecting hole 61 is fitted with a pin 62, and one end of an interlocking arm 63 is rotatably connected to the pin 62. The other end of the interlocking arm 63 is connected and fixed to the other end of the swing arm 42 via an elastic member 64 such as a vibration-proof rubber.

  As shown in FIGS. 4 and 5, a power transmission shaft 67 is disposed near the drive shaft portion 54a of the base 1 with the drive shaft portion 54a and the axis parallel to each other. The power transmission shaft 67 is rotatably supported by a pair of bearings 68.

  A toothed drive pulley 69 is provided at one end of the power transmission shaft 67 and a driven gear 71 is provided at the other end. A toothed belt 72 is stretched between the driving pulley 69 and the driven pulley 66. The driven gear 71 meshes with a drive gear 75 fitted on an output shaft (not shown) of a swing drive source 73 in which a motor and a speed reducer are integrated.

  Accordingly, when the swing drive source 73 is operated and the drive gear 75 is rotationally driven, the rotation is transmitted to the drive shaft portion 54 a of the power transmission shaft 54 via the toothed belt 72 and the driven gear 71. . When the drive shaft portion 54a rotates, the rotation is transmitted to the driven shaft portion 54b via the joint mechanism 55.

  When the drive shaft portion 54a and the driven shaft portion 54b rotate, the interlocking arm 63 having one end connected to the eccentric position of the pair of disks 59 interlocking with the rotation reciprocates. The other end provided with the shoulder massage roller 51 swings about one end where 42 is connected to the attachment member 41 as a fulcrum.

  When the interlocking arm 63 reciprocates, one end connected to the disk 59 moves vertically along with the horizontal movement. However, since the other end of the interlocking arm 63 is connected to the swing arm 42 via the elastic member 64, the elastic member 64 is elastically deformed to absorb the horizontal and vertical movements of the interlocking arm 63. Then, it can be transmitted to the swing arm 42. That is, the interlocking arm 63 performs a crank motion, but can swing the swing arm 42 in the horizontal direction.

  The rotation direction of the drive gear 75 by the swing drive source 73 can be manually or automatically switched between the normal rotation direction and the reverse rotation direction every predetermined time by a remote controller (not shown). Thereby, the rotation direction of the drive shaft portion 54a is switched.

  The rotation of the drive shaft portion 54a is transmitted to the driven shaft portion 54b through the joint mechanism 55. The joint mechanism 55 includes a transmission pin 56 and a transmission member 57 having a semi-cylindrical portion 57a. As shown in FIGS. 4 and 5, the drive shaft portion 57a is rotationally driven in the clockwise direction indicated by an arrow in FIG. 8 in a state where the transmission pin 56 is in contact with the upper end surface 57b of the pair of upper and lower end surfaces of the semi-cylindrical portion 57a. Then, the driven shaft portion 57b waits without being interlocked with the rotation of the drive shaft portion 57a until the drive shaft portion 57a rotates 180 degrees and comes into contact with the lower end surface 57c of the semi-cylindrical portion 57a.

  Similarly, when the rotation direction of the drive shaft portion 57a is changed from the clockwise direction to the counterclockwise direction, the driven shaft portion 57b waits without rotating until the drive shaft portion 57a rotates 180 degrees, and then It rotates in conjunction.

  Therefore, of the pair of left and right swing arms 42, when one of the swing arms 42 on the drive shaft portion 54a side switches the rotation direction of the output shaft 74 of the swing drive source 73, the swing position is indicated by a solid line in FIG. The position is changed from the position indicated by the chain line to the position indicated by the chain line or vice versa, and is then oscillated in conjunction with the other oscillating arm 42 on the driven shaft portion 54b side.

  That is, the pair of oscillating arms 42 are driven to oscillate with the same oscillating phase as shown by the solid line in FIG. 5, or the oscillating phase is shifted so that one is a solid line and the other is a chain line position. In this state, it can be driven to swing.

  The first holding body 21a reciprocally driven in the longitudinal direction of the base body 1 by the driving device 10 is driven to the other longitudinal end portion of the base body 1, which is a position approaching the swing arm 42. When detected by the travel range detection mechanism 17, the swing drive of the swing arm 42 by the swing drive source 73 of the swing drive mechanism 53 is stopped.

  The shoulder massage roller 51 is provided at a portion where the guide rail 4 of the base body 1 is supported by being bent upward by the gantry 6. Therefore, when the main massage roller 35 approaches the shoulder massage roller 51 provided on the swing arm 42, the first holding body 21a provided with the main massage roller 35 is displaced upward as shown in FIG. Travel on the guide rail 4. Accordingly, it is possible to prevent the main massage roller 35 provided on the first holding body 21a from interfering with the shoulder massage roller 51.

  That is, when the first holding body 21a is driven to the shoulder portion of the user, the shoulder portion of the user is massaged by the main massage roller 35, so that the shoulder massage roller 51 is stopped from swinging. The

  As shown in FIGS. 1 and 3, a foamed elastic material 77 such as urethane foam is provided on the upper surface of the base 1 and outside the pair of guide rails 4. Further, the upper surface side and the lower surface side of the substrate 1 are covered with a cover 78 made of stretchable fabric as shown in FIG. A tension is applied to the cover 78. Thereby, the inner surface of the cover 78 is in contact with the main massage roller 35 provided on each of the holding bodies 21a and 21b.

  When a user is massaged by the massage device configured as described above, the user lies on the cover 78 on the upper surface of the base 1. In this state, the pair of holding bodies 21 a and 21 b are driven to reciprocate along the longitudinal direction of the base 1 and the swing drive source 73 of the swing drive mechanism 53 is operated.

  When the pair of holding bodies 21a and 21b are driven to reciprocate, the back surface of the user is massaged over the entire body by the main massage roller 35 provided on each holding body 21a and 21b. At the same time, the swing drive mechanism 53 is operated to swing the swing arm 42 provided with the shoulder massage roller 51.

  Therefore, the user can receive massage by the shoulder massage roller 51 on the shoulder while receiving massage by the main massage roller 35 on the back surface. Obtainable.

  When the first holding body 21a comes close to the shoulder massage roller 51, the first holding body 21a travels on the portion of the guide rail 4 that is bent and supported upward. Moreover, when the first holding body 21a approaches, the swing drive mechanism 53 stops and the shoulder portion of the user is massaged by the main massage roller 35.

  Therefore, the shoulder massage roller 51 does not interfere with the main massage roller 35 provided on the first holding body 21a. Therefore, even if the shoulder massage roller 51 is provided on the base 1, the first holding body 21a is provided. Can be smoothly reciprocated. Moreover, the massage of the user's shoulder is continued by the main massage roller 35 of the first holding body 21a.

  The pair of left and right swing arms 42 provided with the shoulder massage roller 51 are interlocked by a joint mechanism 55. The joint mechanism 55 transmits the rotation of the drive shaft portion 54a of the divided power transmission shaft 54 to the driven shaft portion 54b.

  The rotation direction of the drive shaft portion 54a can be converted. When the rotation direction of the drive shaft portion 54a is changed, the drive shaft portion 54a rotates 180 degrees, and the transmission pin 56 provided at the end portion of the drive shaft portion 54a is transmitted at the end portion of the driven shaft portion 54b. Interlocking is achieved by hitting one of the pair of end faces 57b and 57c of the semi-cylindrical portion 57a of the member 57 to the other.

  Therefore, when the rotation direction of the drive shaft portion 54a is changed, only the swing position of the swing arm 42 on the drive shaft portion 54a side of the pair of swing arms 42 is a position and a chain line shown in FIG. It will be displaced from either one of the indicated positions to the other.

  Therefore, each time the rotation direction of the drive shaft portion 54a is switched, the pair of swing arms 42 swings with respect to the swing arm 42 on the driven shaft portion 54b. Oscillates integrally in the same state or in a shifted state.

  In other words, by changing the rotation direction of the drive shaft portion 54a, the massage state applied to the shoulder portion of the user can be changed, thereby improving the massage effect that the user receives on the shoulder portion due to the change. Can do.

  The swing arm 42 provided with the shoulder massage roller 51 swings when the rotational motion of the drive shaft portion 54a and the driven shaft portion 54b of the power transmission shaft 54 is converted into the reciprocating motion of the interlocking arm 63 and transmitted. Dynamic movement.

  The interlock arm 63 is connected to the swing arm 42 via an elastic member 64. Therefore, the elastic member 64 absorbs the vertical and horizontal movements generated in the interlocking arm 63 by elastic deformation as shown in FIGS. 9A and 9B by the rotational movement of the drive shaft portion 54a and the driven shaft portion 54b. And only transmit linear motion. Therefore, the power transmission shaft 54 can reliably swing the swing arm 42.

  In the embodiment described above, the massage device in which two holding bodies are provided on the base body has been described as an example. However, the number of holding bodies may be one. Further, the number of shoulder massage rollers provided on the swing arm is not limited to two but may be one or three or more.
