JP-A-53-41890 (page 2, page 3, upper left column, FIG. 4)

  In the rolling anomaly of Patent Document 1, the convex portion of the roller can apply a rotational stimulus to the skin surface along the direction of rotation of the roller, forcibly pumping blood and lymph fluid at the stimulation site to the lower side in the rotational direction. You can eliminate blood congestion. Thereby, the blood flow of a stimulation site | part can be improved and skin can be activated and the beauty effect can be acquired. However, since the rotation locus | trajectory of an adjacent roller is separated, the space | interval of adjacent rollers becomes wide and lacks in compactness.

An object of the present invention is to provide a rotary beauty device with improved compactness.
Another object of the present invention is to provide a beauty device that can improve the effect of pumping blood or lymph by rotational stimulation and can effectively obtain a beauty effect.

  The cosmetic device according to the present invention includes a plurality of adjacent rotating bodies 14 that are driven to rotate about parallel axes. Each rotating body 14 is provided with at least one pressing body 15 that applies a rotational stimulus to the skin surface. Each rotating body 14 is arranged in a state where the rotation trajectories T of the adjacent pressing bodies 15 overlap each other.

  Each rotating body 14 is rotationally driven in the same direction by the drive mechanism 13.

  The phase positions of the pressing bodies 15 provided on the respective rotating bodies 14 are different between adjacent rotating bodies 14.

  The diameter of the rotation locus T of each pressing body 15 is set to be the same.

  The rotational speed of each rotating body 14 is set to be the same.

  Of the adjacent rotators 14, the rotation speed of the rotator 14 positioned on the lower side in the rotation direction is set to be faster than the rotation speed of the rotator 14 positioned on the upper side in the rotation direction.

  The rotating body 14 is fixed to the drive shaft 20. Adjacent rotators 14 are alternately arranged near one end and the other end of each drive shaft 20 so as to face each other in the direction of the rotation axis. The pressing body 15 in each rotating body 14 is provided so as to project toward the opposing opposing rotating body 14.

  The rotating body 14 is fixed to the drive shaft 20. The pressing body 15 is formed as an outer protrusion 40 on the peripheral surface of the rotating body 14 formed of a plate-like body.

  One end of the pressing body 15 made of a rod-shaped body is attached to the rotation plane of the rotating body 14. The tip 15a of the pressing body 15 protruding from the rotating body 14 and the peripheral surface 15b continuous to the tip 15a can be applied to the skin surface with rotational stimulation.

  When the rotating bodies 14 are arranged in a state where the rotation trajectories T of the adjacent pressing bodies 15 overlap each other, the beauty device can be reduced in size and made compact by the amount that the adjacent distance between the pressing bodies 15 becomes smaller.

  When each rotating body 14 is driven to rotate in the same direction by the drive mechanism 13, it is possible to apply rotational stimulation to the skin surface along the rotational direction of the rotating body 14, forcing blood and lymph fluid at the stimulation site. Can be pumped to the lower side in the rotational direction.

  Since the phase positions of the pressing bodies 15 provided in the respective rotating bodies 14 are made different between the adjacent rotating bodies 14, the pressing bodies 15 of the adjacent rotating bodies 14 simultaneously contact the skin surface to apply rotational stimulation. Can be avoided. Thereby, it is possible to prevent the flow of blood and lymph fluid pumped by the pressing body 15 from being blocked by the lower pressing body 15 and reducing the pumping effect. Therefore, the effect of pumping blood or lymph by rotational stimulation can be improved.

  When the diameter of the rotation locus T of each pressing body 15 is set to be the same, the contact state of the pressing body 15 with the skin surface can be made the same with each pressing body 15, and a rotational stimulus is applied to the skin surface. The skin per touch can be made uniform.

  When the rotational speeds of the rotating bodies 14 are set to be the same, a rotational stimulus can be imparted to the skin surface with a good rhythm, and the beauty device can be used comfortably and comfortably.

  If the rotation speed of the rotation body 14 located on the lower side in the rotation direction among the adjacent rotation bodies 14 is set faster than the rotation speed of the rotation body 14 located on the upper side in the rotation direction, the lower pressure body 15 is pressed. Can quickly pump blood and lymph fluid pumped from the upper side to the lower side in the rotational direction without stagnation. Accordingly, it is possible to further improve the effect of pumping blood or lymph by rotational stimulation.

  In the beauty device, adjacent rotating bodies 14 are alternately arranged near one end and the other end of each drive shaft 20 and face each other in the direction of the rotation axis, and the pressing body 15 in each rotating body 14 is on the opposite side. It is possible to adopt a form that projects toward the rotating body 14. According to this, it is possible to prevent the adjacent rotating bodies 14 from interfering with each other and to overlap the rotation trajectory T of the pressing body 15, and to continuously provide the rotation stimulus application range by the pressing body 15 in a straight line. The blood and lymph can be reliably pumped from the upper side to the lower side in the rotational direction of the rotating body 14.

  When the pressing body 15 is formed as an outer protrusion 40 on the circumferential surface of the rotating body 14 formed of a plate-like body, it acts in the center direction of the rotating body 14 when a rotational stimulus is applied to the skin surface. The reaction force from the skin surface can be received by the rotating body 14 and the drive shaft 20. Thereby, for example, even when the pressing body 15 is pressed against the skin surface with a strong force, the pressing body 15 can be reliably prevented from being deformed or damaged.

  According to the cosmetic device in which one end of the pressing body 15 made of a rod-like body is attached to the rotation plane of the rotating body 14, the skin is formed by the distal end portion 15a of the pressing body 15 protruding from the rotating body 14 and the peripheral surface portion 15b continuous to the distal end portion 15a. A rotational stimulus can be applied to the surface. In addition, since different rotational stimuli can be applied to the skin surface between the distal end portion 15a and the peripheral surface portion 15b of the pressing body 15, a beauty device that can apply different rotational stimuli to the skin surface can be provided.

First Embodiment FIGS. 1 to 5 show a first embodiment applied to a hand-held massager (beauty device) (hereinafter simply referred to as a massager). Note that front / rear, left / right, and upper / lower follow the cross arrows shown in FIGS. 1, 2, and 4 and the front / rear, left / right, and upper / lower indications shown near each arrow. In FIG. 2, the massage device includes a vertically long main body case 1, the upper half of the main body case 1 is configured as a massage head 2, and a massage unit 3 is disposed inside the massage head 2. The lower half of the main body case 1 also serves as a grip 4, and a motor 5 that drives the massage unit 3, a battery 6 that supplies a driving current to the motor 5, and a control that controls the operation of the motor 5. A substrate 7 and the like are arranged. The motor 5 is activated by turning on an operation switch 8 provided on the front surface of the grip 4 to drive the massage unit 3. In FIG. 2, reference numeral 9 is a forward / reverse switch for switching the rotation direction of the motor 5.

  As shown in FIGS. 3 and 4, the massage unit 3 includes a support base 12, a drive mechanism 13 disposed on the support base 12, and three disk-shaped turntables that are rotationally driven by the drive mechanism 13 ( (Rotary body) 14 and pressing rods (pressing bodies) 15 provided on each rotary table 14. The pressing rod 15 is composed of a rod-shaped body composed of a roller shaft 16 having an upper end formed in a hemispherical shape and a cylindrical roller 17 rotatably supported by the roller shaft 16, and the lower end of the roller shaft 16. Is fixed to the rotation plane of the turntable 14. The roller 17 has a circular cross-sectional shape. When the pressing rod 15 is composed of the roller shaft 16 and the roller 17, the friction between the pressing rod 15 and a cover 29 described later can be reduced when a rotational stimulus is applied. It can be prevented from being damaged.

  As shown in FIG. 1, each rotary table 14 is provided with two pressing rods 15, and each pressing rod 15 is provided at a point-symmetrical position with respect to the rotation center of the rotary table 14. The diameter of the rotation trajectory T of each pressing rod 15 when the turntable 14 is rotationally driven is set to be the same. The pressing bar 15 can impart a rotational stimulus to the skin surface with a hemispherical hemispherical surface (tip portion) 15a at the upper end of the roller shaft 16 and a peripheral surface (peripheral surface portion) 15b of the roller 17 continuous with the hemispherical surface 15a. Each turntable 14 is arranged in a state in which the respective rotation axes are arranged in parallel on the same plane. Further, each turntable 14 is arranged so that the rotation trajectory T of the adjacent pressing rod 15 does not interfere. The three turntables 14 are the same member, and are respectively fixed to a drive shaft (rotary shaft) 20 described later.

  As shown in FIGS. 3 and 4, the drive mechanism 13 includes a drive gear 19 fixed to the central drive shaft 20, a passive gear 21 fixed to the left and right drive shafts 20, and both the gears 19 and 21. It is comprised with the counter gear 22 arrange | positioned between. Each of the drive shaft 20 and the gear shaft 23 that supports the counter gear 22 is rotatably supported by a bearing body (not shown) provided on the support base 12, and the central drive shaft 20 penetrates the support base 12. And it is extended downward. The motor shaft of the motor 5 is connected to a speed reducer 25, and the output shaft of the speed reducer 25 and the lower end of the central drive shaft 20 are connected by a coupling 26.

  When the operation switch 8 is turned on to drive the motor 5, the central drive shaft 20 is rotationally driven via the speed reducer 25, and the central rotary table 14 and the drive gear 19 are rotationally driven. The rotation of the drive gear 19 is transmitted to the left and right passive gears 21 via both counter gears 22 and rotationally drives the turntable 14 fixed to the left and right drive shafts 20. At this time, the three turntables 14 are rotationally driven in the same direction. Since the drive gear 19 and the two passive gears 21 have the same number of teeth, and the two counter gears 22 have the same number of teeth, the rotation speeds of the turntables 14 are set to be the same. When the motor 5 is rotated in the forward direction, each turntable 14 is set to rotate counterclockwise in FIG. 1, and its rotation speed is set to 60 rpm.

  As shown in FIGS. 1 and 4, the massage head 2 has an opening 28 formed on the upper surface and the front and rear surfaces continuous with the upper surface. The pressing rod 15 of each turntable 14 is disposed so as to face the opening 28, and the rotation trajectory T of each pressing rod 15 protrudes from the front and rear surfaces of the opening 28 to the outside of the main body case 1. Further, the tip portion of each pressing rod 15 protrudes from the upper surface of the opening 28 to the outside of the main body case 1. The opening 28 is covered with a flexible cover 29 so that a part of the pressing bar 15 protruding to the outside of the main body case 1 does not directly contact the skin surface or the like. By driving the motor 5 and bringing the massage head 2 into contact with the skin surface, rotational stimulation can be applied to the skin surface by the hemispherical surface 15a or the peripheral surface 15b of each pressing rod 15 through the cover 29. When the front surface or the rear surface of the massage head 2 is brought into contact with the skin surface, a linear rotational stimulus can be applied to the skin surface along the rotation direction by the peripheral surface 15b of the pressing rod 15, and the massage surface can be massaged. When the upper surface of the head 2 is brought into contact with the skin surface, a rotational stimulus that rotates on the hemispherical surface 15a can be applied to the skin surface.

  This embodiment is characterized in that the phase position of the pressing rod 15 provided on each turntable 14 is different between adjacent turntables 14. As shown in FIG. 1, when the pressing rod 15 of the turntable 14 arranged at the right end is at the front and rear end positions, each of the pressing rods 15 of the turntable 14 arranged at the center is clockwise in a plan view. Are provided at positions that are different in phase by 60 degrees. Further, the pressing rod 15 of the turntable 14 arranged at the left end is provided at a position where the phase is further varied by 60 degrees in the clockwise direction. Thereby, for example, when the rear surface of the massage head 2 is brought into contact with the skin surface, a rotational stimulus is applied to the skin surface of the pressing bar 15 of the right turntable 14 (FIG. 5A), and then the center turntable 14. The pressing bar 15 gives a rotational stimulus to the skin surface (FIG. 5B). Next, the pressing bar 15 of the left turntable 14 gives a rotational stimulus to the skin surface (FIG. 5C). In this way, linear rotation stimulation along the rotation direction can be given to the skin surface in order from the peripheral surface 15b of the pressing bar 15 from the upper side to the lower side in the rotation direction of the turntable 14. In the case where the massage head 2 is brought into contact with the skin surface by making the rotation direction of the turntable 14 coincide with the blood flow direction, a linear rotational stimulus is applied to the skin surface to rotate the blood or lymph. Can be pumped to the lower side. This rotational stimulus is accompanied by a pressing stimulus by the pressing rod 15 in addition to a linear rubbing operation.

  In the massage device according to the present embodiment, the three turntables 14 are rotationally driven by one motor (drive source) 5. For this reason, for example, if the phase positions of the adjacent pressing bars 15 are the same, the three pressing bars 15 press the skin surface at the same timing. Load acts. However, if the phase positions of the pressing bars 15 provided on the respective rotating bases 14 are made different between the adjacent rotating bases 14, the plurality of pressing bars 15 do not give rotational stimulation to the skin surface at the same timing, and the motor 5 The life of the motor 5 can be improved by avoiding an increase in the load acting on the motor 5.

  As described above, in the massage device of the present embodiment, the phase position of the pressing bar 15 provided on each turntable 14 is varied between the adjacent turntables 14. At the same time, it is possible to avoid applying a rotational stimulus accompanied by pressing by touching the skin surface. Thereby, it is possible to prevent the flow of blood or lymph fluid pumped by the pressing rod 15 from being blocked by the lower pressing rod 15 and reducing the pumping effect. Accordingly, it is possible to improve the blood and lymph pumping effect due to the rotational stimulation accompanied by pressing, and to effectively obtain the cosmetic effect. The position of the pressing bar 15 provided on each turntable 14 can be made different in phase position by only attaching each turntable by shifting it by a predetermined angle (60 degrees in this embodiment) when the turntable 14 is assembled. Therefore, the structure of the massage unit 3 is not complicated.

  Moreover, since the diameter of the rotation locus | trajectory T of each press stick | rod 15 is set equally, the contact state to the skin surface of the press stick | rod 15 can be made the same with each press stick | rod 15, and the skin at the time of giving a rotation stimulus The contact can be made uniform. Furthermore, since the rotation speed of each turntable 14 is set to be the same, a rotational stimulus can be given to the skin surface with a good rhythm, and the massager can be used comfortably and comfortably. Specifically, in this embodiment, as the right turntable 14 moves from the right turntable 14 to the left turntable 14, the phase position of the pressing bar 15 is set to 60 degrees in the clockwise direction opposite to the rotation direction of the turntable 14. They are arranged with their phases shifted. Thereby, for example, when the rear surface of the massage head 2 is brought into contact with the skin surface, the skin surface is regularly arranged in order from the pressing rod 15 of the right turntable 14 to the pressing rod 15 of the left turntable 14. A rotational stimulus is applied to the. That is, rotational stimulation accompanied by pressing by the pressing bar 15 can be applied to the skin in order with the same time difference between right, center, left, and then right.

  Since the hemispherical surface 15a of the pressing bar 15 made of a rod projecting from the turntable 14 and the peripheral surface 15b continuous to the hemispherical surface 15a can be applied to the skin surface, the hemispherical surface 15a of the pressing bar 15 With the peripheral surface 15b, it is possible to apply different rotational stimuli between the rotating rotational stimulus and the linear rotational stimulus to the skin surface, and it is possible to provide a massager that can apply various rotational stimuli to the skin surface.

  The massage device (beauty device) provided with the said structure can be implemented with the following form. That is, a plurality of turntables (rotators) 14 that are driven to rotate around parallel axes are provided, and each turntable 14 has at least one pressing bar (pressing body) 15 that gives a rotational stimulus to the skin surface. Each rotary table 14 is rotationally driven in the same direction by a drive mechanism 13 driven by one motor (drive source) 5, and the phase of the pressing rod 15 provided on each rotary table 14. A massager whose position is varied between adjacent turntables 14.

  As described above, the life of the motor 5 can be improved by making the phase position of the pressing rod 15 provided on each turntable 14 different between adjacent turntables 14. Specifically, for example, if the phase positions of the adjacent pressing bars 15 are the same, the motor while the plurality of pressing bars 15 press the skin surface at the same timing and give a rotational stimulus accompanied by pressing. A large load acts on 5. However, if the phase positions of the pressing bars 15 provided on the respective rotating bases 14 are made different between the adjacent rotating bases 14, the plurality of pressing bars 15 do not impart rotational stimulation to the skin surface at the same timing. Therefore, it is possible to avoid an increase in the load acting on the motor 5 and improve the life of the motor 5. Further, consumption of the battery 6 due to a large load acting on the motor 5 can be suppressed. Furthermore, the heating of the motor 5 due to the load can be prevented, and the reliability of the massager can be improved.

  In the above embodiment, the pressing rod 15 (roller 17) has a circular cross-sectional shape, but may be formed in a non-circular roller shape, an elliptical shape, or a polygonal shape. The pressing rod 15 does not need to be composed of the roller shaft 16 and the roller 17, and may be a round shaft with a rounded tip. In this case, the rounded tip functions as the tip portion 15a, and the peripheral surface of the round shaft functions as the peripheral surface portion 15b.

Second Example FIG. 6 shows a second example of the beauty equipment. The beauty device (massage device) according to the second embodiment is different from the massage device of the first embodiment in that the shape of the roller 17 of the pressing bar 15 is changed. Since the other points are the same as those in the first embodiment, the same members are denoted by the same reference numerals and the description thereof is omitted. The same applies to the following embodiments.

  The roller 17 is composed of a roller cylinder 32 and four stimulation rollers 33 projecting in a circular shape on the outer peripheral surface of the roller cylinder 32. As described above, when the stimulation roller 33 is formed on the outer peripheral surface of the roller cylinder 32, the contact area between the pressing bar 15 and the skin surface is reduced, and the massage head 2 is lightly pressed against the skin surface to apply a strong press. The accompanying rotational stimulus can be applied to the skin surface. Also in this example, the rotation speed of the turntable 14 was set to 60 rpm.

(Third Embodiment) FIGS. 7 to 10 show a beauty apparatus according to a third embodiment. The beauty device (massage device) according to the third embodiment is different from the massage device of the first embodiment in that the opening 28 is provided on the front surface of the body case 1 that is long on the left and right and the configuration of the massage unit 3 is changed. Different. In FIG. 7, the massage device includes a horizontally long main body case 1, the left half of the main body case 1 is configured as a massage head 2, and the massage unit 3 is disposed inside the massage head 2. The right half of the main body case 1 also serves as the grip 4, and a motor 5, a battery 6, a control board 7, and the like are disposed therein. The operation switch 8 and the forward / reverse switch 9 are provided on the upper surface of the grip 4.

  As shown in FIGS. 8 to 10, the massage unit 3 is rotationally driven by a pair of support bases 12 disposed above and below, a drive mechanism 13 disposed between the pair of support bases 12, and the drive mechanism 13. It is composed of three disk-shaped rotating tables (rotating bodies) 14 and columnar pressing rods (pressing bodies) 15 provided on each rotating table 14. The turntable 14 is fixed to the drive shaft 20, and adjacent turntables 14 are alternately arranged near one end and the other end of each drive shaft 20 so as to face each other in the direction of the rotation axis. Each turntable 14 is provided with a single pressing rod 15 projecting toward the opposite turntable 14. The three turntables 14 are the same member, and are arranged in a state where the respective rotation centers are arranged in parallel on the same plane, and the outer shapes of the adjacent turntables 14 are overlapped. When the turntable 14 is driven to rotate, the diameter of the rotation trajectory T of each pressing rod 15 is set to be the same, and the rotation trajectory T of the adjacent pressing rod 15 is the rotation of the turntable 14 as shown in FIG. Overlapping when viewed in the axial direction. As shown in FIG. 8, the entire pressing bar 15 on one side of the adjacent rotating table 14 is within the rotation trajectory T of the pressing bar 15 on the other side of the adjacent rotating table 14 as viewed in the rotation axis direction of the rotating table 14. It overlaps so that it may enter. For example, when the left pressing rod 15 further rotates clockwise as viewed in FIG. 8, it approaches the drive shaft (rotating shaft) 20 of the center turntable 14. When the left pressing rod 15 is closest to the drive shaft (rotating shaft) 20 of the central turntable 14, the entire left pressing rod 15 is within the rotation locus T of the central pressing rod 15 as viewed in the direction of the rotation axis. Fits comfortably. That is, when the pressing bar 15 on one side of the adjacent turntable 14 comes closest to the drive shaft (rotating shaft) 20 of the adjacent turntable 14 on the other side, the pressing bar 15 on the one side and the pressing bar on the other side. The 15 rotation trajectories T overlap so that a predetermined distance can be obtained.

  As shown in FIGS. 7 and 9, the drive mechanism 13 includes three drive shafts 20, passive gears 21 fixed to the respective drive shafts 20, worm shafts 35 that drive the respective passive gears 21, and worm shafts. And a drive gear 36 provided at the right end of 35. Each drive shaft 20 is rotatably supported by a bearing body (not shown) provided on the pair of support bases 12. The first stage gear of the speed reduction mechanism 37 constituted by a gear group is fixed to the motor shaft of the motor 5, and the last stage gear of the speed reduction mechanism 37 is engaged with the drive gear 36.

  When the operation switch 8 is turned on to drive the motor 5, the drive gear 36 and the worm shaft 35 are rotationally driven via the speed reduction mechanism 37. Thereby, the three passive gears 21 are rotationally driven by the worm shaft 35, and the rotary base 14 fixed to each drive shaft 20 can be rotationally driven in the same direction. The three passive gears 21 are composed of gears having the same number of teeth, and the rotation speeds of the turntables 14 are set to be the same. When the motor 5 is rotated forward, each turntable 14 is set to rotate clockwise in FIG. 8, and the number of rotations is set to 60 rpm.

  As shown in FIGS. 9 and 10, the massage head 2 has an opening 28 formed on the front surface, and the opening 28 is covered with a cover 29 having flexibility. The rotation trajectory (T) of the pressing rod 15 of each turntable 14 protrudes from the front and rear surfaces of the opening 28 to the outside of the main body case 1. When the front surface of the massage head 2 is brought into contact with the skin surface, the peripheral surface 15b of the pressing bar 15 can apply a rotational stimulus accompanied by a linear press along the rotation direction to the skin surface.

  As shown in FIG. 8, when the pressing rod 15 of the turntable 14 arranged at the right end is at the front end position, the pressing rod 15 of the turntable 14 arranged at the center is counterclockwise in plan view. It is provided at a position where the phase is different by 60 degrees. The pressing rod 15 of the turntable 14 disposed at the left end is provided at a position where the phase is further varied by 60 degrees in the counterclockwise direction. As a result, when the front surface of the massage head 2 is brought into contact with the skin surface, the pressing bar 15 of the right turntable 14 gives rotational stimulation to the skin surface, and then the press bar 15 of the center turntable 14 touches the skin surface. Apply rotational stimulation. Next, the pressing bar 15 of the left turntable 14 gives a rotational stimulus to the skin surface. In this way, a rotational stimulus accompanied by a linear pressing can be applied to the skin surface in order from the peripheral surface 15b of the pressing bar 15 from the upper side to the lower side in the rotational direction of the turntable 14.

  As described above, in the massage device of the present embodiment, each turntable 14 is arranged in a state where the rotation trajectories T of the adjacent pressing bars 15 overlap with each other, so that the distance between the adjacent pressing bars 15 is reduced. be able to. Thereby, the skin surface part which is located between the adjacent press bars 15 and to which rotation stimulus is not given can be made as narrow as possible, and rotation stimulus can be given evenly to the skin surface. Further, the beauty device can be reduced in size and made compact by the amount that the adjacent distance of the pressing bar 15 becomes smaller. Furthermore, since the adjacent turntables 14 are configured to rotate in the same direction, the effect of pumping blood and lymph fluid by rotational stimulation can be improved in combination with the decrease in the adjacent distance of the pressing rod 15. In addition, in the present Example, although the turntable 14 becomes a structure rotated in the same direction, the structure which the adjacent turntable 14 rotates in a reverse direction may be sufficient. In this case, if the adjacent turntables 14 are simultaneously brought into contact with the skin surface, a rotation stimulus accompanied by a stagnation action by the plurality of turntables 14 can be applied, and one turntable 14 at the end is applied to the skin surface. If they are brought into contact with each other, it becomes possible to pump blood or lymph by one-way rotational stimulation.

  Adjacent turntables 14 are alternately arranged near one end and the other end of each drive shaft 20 and face each other in the direction of the rotation axis, and the pressing rod 15 in each turntable 14 is a turntable on the opposite side. 14 is provided so that blood and lymph can be reliably supplied from the upper side to the lower side in the rotational direction of the turntable 14 by continuously linearly providing the range of rotation stimulation applied by the pressing rod 15. Can be pumped.

(Fourth Embodiment) FIGS. 11 to 13 show a beauty apparatus according to a fourth embodiment. The beauty device (massage device) according to the fourth embodiment differs from the massage device of the first embodiment in that the opening 28 is provided on the upper surface of the main body case 1 and the configuration of the massage unit 3 is changed. In FIG. 11, the massage device includes a main body case 1, the upper half of the main body case 1 is configured as a massage head 2, and the massage unit 3 is disposed inside the massage head 2. A main body case 1 extending downward from the rear end of the massage head 2 also serves as a grip 4, and a motor 5, a battery 6, a control board 7, and the like are disposed therein.

  As shown in FIGS. 12 and 13, the massage unit 3 includes a pair of front and rear support bases 12, a drive mechanism 13 disposed between the pair of support bases 12, and a circular plate that is rotationally driven by the drive mechanism 13. The rotating body 14 is composed of four rotating bodies 14 and pressing bodies 15 provided on each rotating body 14. The pressing body 15 is formed as an outer protrusion 40 on the peripheral surface of the rotating body 14, and the three rotating tables 14 are provided with three protrusions 40 at equal angular intervals.

  The rotating body 14 is fixed to the drive shaft 20, and the adjacent rotating bodies 14 are arranged in a state where the outer shapes overlap with each other while being shifted in the direction of the rotation axis. The four turntables 14 are the same member, and when the turntable 14 is rotationally driven, the diameters of the rotation trajectories T of the pressing bodies 15 are set to be the same, and the rotation trajectories T of the protrusions 40 are the rotation bodies. 14 in the direction of the rotation axis. As shown in FIG. 12, the entire protrusion 40 on one side of the adjacent rotating body 14 is within the rotation trajectory T of the protrusion 40 on the other side of the adjacent rotating body 14 in the rotational axis direction view of the rotating body 14. It overlaps so that it may enter. For example, when the left protrusion 40 further rotates counterclockwise toward FIG. 12, it approaches the rotation axis of the central rotating body 14. When the left protrusion 40 comes closest to the rotation axis of the central rotating body 14, the entire left protrusion 40 fits within the rotation locus T of the central protrusion 40 as viewed in the direction of the rotation axis. That is, when the protrusion 40 on one side of the adjacent rotating body 14 comes closest to the rotation axis of the protrusion 40 of the adjacent rotating body 14 on the other side, the protrusion 40 on one side and the protrusion 40 on the other side are located. Are overlapped so that a predetermined distance can be obtained. The four turntables 14 are in a state where the diameters of the rotation trajectories T of the pressing bodies 15 when the respective turntables 14 are rotationally driven are set different from each other, and the rotation trajectories T of the protrusions 40 are over. It may be wrapped.

  As shown in FIGS. 12 and 13, the drive mechanism 13 includes two drive shafts 20, a passive gear 21 fixed to each drive shaft 20, and a drive gear 41 disposed between the passive gears 21. Has been. The drive shaft 20 is rotatably supported by a bearing body (not shown) provided on the support base 12. The left and right passive gears 21 have different numbers of teeth, and the passive gear 21b fixed to the left drive shaft 20 has fewer teeth than the passive gear 21a fixed to the right drive shaft 20. Has been. A pinion gear of a speed reduction mechanism 42 composed of a pinion gear and a face gear is fixed to the motor shaft of the motor 5, and the face gear and the drive gear 41 are connected by a rotating shaft. A pinion gear is fixed to the output shaft of the motor 5, and a reduction mechanism 42 is constituted by the pinion gear and the face gear. The previous drive gear 41 is fixed to a gear shaft fixed to the face gear.

  When the motor 5 is driven by turning on the operation switch 8, the drive gear 41 is rotationally driven via the speed reduction mechanism 42, and thereby the left and right passive gears 21 a and 21 b are driven and attached to each drive shaft 20. The turntable 14 can be rotated. Each turntable 14 is set to rotate counterclockwise in FIG. Since the number of teeth of the left passive gear 21b is set to be small, the rotation speed of the left turntable 14, which is the lower side in the rotation direction, is rotationally driven faster than the rotation speed of the right turntable 14. In this example, the rotation speed of the left turntable 14 was set to 80 rpm, and the rotation speed of the right turntable 14 was set to 60 rpm.

  As shown in FIG. 12, the massage head 2 has an opening 28 formed on the upper surface, and the opening 28 is covered with a cover 29 having flexibility. Each turntable 14 is disposed so as to face the opening 28, and the rotation trajectory T of each protrusion 40 protrudes outward from the upper surface of the main body case 1. The turntable 14 arranged on the right side and the turntable 14 arranged on the left side are fixed to the drive shaft 20 with the position of the protrusion 40 shifted by 60 degrees. When the upper surface of the massage head 2 is brought into contact with the skin surface, a linear rotational stimulus can be applied to the skin surface by the protrusion 40. Also in this embodiment, since the rotation trajectories T of the protrusions 40 overlap, the distance between the adjacent protrusions 40 can be reduced. Thereby, the skin surface part which is located between the adjacent protrusions 40 and to which no rotational stimulus is applied can be made as narrow as possible, and the rotational stimulus can be applied evenly to the skin surface. In addition, the beauty device can be made smaller and more compact by the amount that the adjacent distance between the protrusions 40 becomes smaller. Furthermore, since the adjacent turntables 14 are configured to rotate in the same direction, the effect of pumping blood or lymph fluid by rotational stimulation can be improved in combination with the decrease in the adjacent distance of the pressing body 15. In this embodiment as well, the turntable 14 is configured to rotate in the same direction, but the adjacent turntable 14 can be configured to rotate in the reverse direction. In this case, if the adjacent turntables 14 are simultaneously brought into contact with the skin surface, a rotation stimulus accompanied by a stagnation action by the plurality of turntables 14 can be applied, and one turntable 14 at the end is applied to the skin surface. If they are brought into contact with each other, it becomes possible to pump blood or lymph by one-way rotational stimulation.

  Further, in this embodiment, when assembling the massager, the phase position of the protrusion 40 is fixed to the drive shaft 20 while being shifted by 60 degrees. However, when the massager is operated, the rotational speeds of the left and right turntables 14 are different. For this reason, the phase position of the protrusion 40 always changes. Accordingly, the protrusions 40 of the two turntables 14 may also come into contact with the skin surface at the same time, but this is temporary, and most of the protrusions 40 on the left and right when applying a rotational stimulus to the skin surface. A rotational stimulus can be applied by contacting at different timings.

  As described above, when the rotation speed of the turntable 14 located on the lower side in the rotation direction among the adjacent turntables 14 is set higher than the rotation speed of the turntable 14 located on the upper side in the rotation direction, the lower-side collision occurs. The unit 40 can quickly pump blood and lymph fluid pumped from the upper side without stagnation. Therefore, the effect of pumping blood or lymph by rotational stimulation can be further improved, and a beauty effect can be obtained effectively. The rotation stimulus is accompanied by a linear rubbing operation in which the protrusion 40 rotates in one direction in addition to the pressing by the protrusion 40, and also has the effect of pumping blood or lymph. As a rotational stimulus, if the rotary table 14 does not have the protrusion 40 and is a simple circular rotary table 14, a linear rubbing motion that rotates in one direction with weak pressing can be performed. Since it has a pumping effect, it also includes a rotational stimulus with such a weak press. Furthermore, even if the turntable 14 does not have the protrusions 40, if the turntable 14 is made elliptical, it can be a rotational stimulus with substantially the same pressure as in the above embodiment.

(Fifth Embodiment) FIG. 14 shows a fifth embodiment of a beauty device. The beauty device (massage device) according to the fifth embodiment is different from the massage device of the fourth embodiment in that the protrusion 40 is formed separately from the rotating body 14. As shown in FIG. 14, the protrusion 40 is constituted by a sphere 45 fitted in a holding recess 44 formed on the peripheral surface of the rotating body 14. Thus, if the protrusion 40 is comprised with the spherical body 45, when providing a rotation stimulus, the friction between the protrusion 40 and the cover 29 can be reduced, and it can prevent that the cover 29 is damaged. Also in this example, the rotation speed of the left turntable 14 was set to 80 rpm, and the rotation speed of the right turntable 14 was set to 60 rpm.

  In the first to fifth embodiments, the rotary base (rotating body) 14 and the drive gear 19 or the drive gear 20 to which the passive gear 21 is fixed and the gear shaft 23 to which the counter gear 22 is fixed are the support base. The drive shaft 20 and the gear shaft 23 can be fixed to the support base 12. In this case, the rotary base 14 and the passive gear 21 are connected and fixed, and the 14 and 21 are rotatably supported with respect to the drive shaft 20 fixed to the support base 12.

(Sixth Example) FIGS. 15 to 17 show a sixth example applied to a hand-held massager (beauty device). In FIG. 15, the massage device includes a main body case 1 and a massage head 2 extending outward from the right side surface of the main body case 1. The massage head 2 includes a massage unit 3 and a unit cover 55 that covers the massage unit 3. The main body case 1 also serves as the grip 4, and a motor 5, a battery 6, a control board 7, and the like are disposed therein. The operation switch 8 and the forward / reverse switch 9 are provided on the front surface of the grip 4.

  As shown in FIGS. 15 and 17, the massage unit 3 includes a driving mechanism 13, a pair of upper and lower rotating tables (rotating bodies) 14 that are rotationally driven by the driving mechanism 13, and pressing bars ( And a pair of upper and lower movable frames (frames) 51 that pivotally support adjacent drive shafts 20. The pressing rod 15 is disposed between a pair of turntables 14 and is formed of a rod-shaped body including a roller shaft 16 and a cylindrical roller 17 that is rotatably supported by the roller shaft 16. The upper and lower ends of the roller shaft 16 are fixed to the upper and lower turntables 14, and the cross-sectional shape of the roller 17 is formed in a circular shape.

  As shown in FIG. 17, two pressing rods 15 are provided between the pair of rotary tables 14, and these pressing rods 15 are provided at positions that are point-symmetric with respect to the rotation center of the rotary table 14. ing. The diameter of the rotation trajectory T of each pressing rod 15 when the turntable 14 is driven to rotate is set to be the same, and the pressing rod 15 is a circumferential surface (peripheral surface portion) 15b of the roller 17 and rotationally stimulates the skin surface. Can be granted. Each turntable 14 is fixed to the drive shaft 20.

  As shown in FIG. 15, the drive mechanism 13 includes five drive shafts 20, passive gears 21 that are fixed to the drive shafts 20 and transmit power from the motor 5 to the turntable 14, and adjacent passive gears 21. And a counter gear 22 which is disposed between and interlocks with each other. Adjacent drive shafts 20 are pivotally supported by a pair of upper and lower movable frames 51 so as to be rotatable in the front-rear direction, and the drive shaft 20 at the left end of each drive shaft 20 and each movable frame 51 is connected to the body case 1. The base frame 52 is pivotally supported by the base frame 52 so as to be rotatable in the front-rear direction and supported by the main body case 1. Thereby, the adjacent turntable 14 and the movable frame 51 can be rotated around the drive shaft 20 on the adjacent counterpart side as the rotation center. A bearing body (not shown) is provided between the movable frame 51 and the base frame 52 and the drive shaft 20. The counter gear 22 is fixed to a gear shaft 23 that is rotatably supported by both frames 51 and 52.

  As shown in FIGS. 16 and 17, the rotational axis of the passive gear 21 and the axis P of the drive shaft 20 are matched. As a result, when the turntable 14 is turned around the axis P of the drive shaft 20 on the adjacent counterpart side, the counter gear 22 is not changed in engagement depth with respect to the passive gear 21. The meshing position moves by an angle obtained by rotating 14. The same applies when the adjacent turntables 14 are rotated. Thus, when the rotational axis of the passive gear 21 that transmits power to the turntable 14 and the axial center P of the drive shaft 20 are matched, the adjacent passive gear 21 and the counter gear that meshes with and is interlocked with the passive gear 21. The adjacent turntables 14 can be refracted from each other with the axis P of each drive shaft 20 as the center of rotation, without changing the meshing depth with 22. Accordingly, even when the overall arrangement of the turntable 14 is changed in various ways, it is possible to prevent generation of noise and rattling at the meshing portion, and power can be reliably transmitted to each turntable 14. it can.

  The upper and lower movable frames 51 arranged at the right end are connected by a gripping bar 53, and the gripping bar 53 functions as a grip part when applying a rotational stimulus to the skin surface. By fixing the main body case 1 with one hand and moving the gripping rod 53 in the front-rear direction with the other hand, the adjacent turntables 14 are rotated about the drive shaft 20 as a rotation center, and the massage head 2 can be freely refracted. Although not shown, a stopper structure is provided between the adjacent frames 51, and an angle at which the frame 51 can be refracted is regulated.

  The motor shaft of the motor 5 is connected to the speed reducer 25, and a drive gear 54 is fixed to the output shaft of the speed reducer 25. The drive gear 54 and the leftmost passive gear 21 are meshed with each other via the counter gear 22, and the drive gear 54, the five passive gears 21, and the five counter gears 22 constitute a gear train. Yes. As a result, the rotation of the drive gear 54 is transmitted to the final passive gear 21 via the counter gear 22, and each turntable 14 is rotationally driven. Since the number of teeth of the five passive gears 21 is the same, and the number of teeth of the five counter gears 22 is also the same, each turntable 14 is driven to rotate simultaneously at the same speed in the same direction. When the motor 5 is rotated in the forward direction, each turntable 14 is set to rotate counterclockwise in FIG. 17, and the rotation speed is set to 60 rpm.

  As shown in FIG. 15, the phase positions of the pressing rods 15 provided on each turntable 14 are different between adjacent turntables 14. When the rotation centers of the turntables 14 are on the same plane, they are adjacent to each other. The pressing bodies 15 are provided in a state where the phase positions are different by 60 degrees.

  As described above, when the adjacent rotating bodies 14 are supported so as to be able to rotate about the adjacent driving shaft 20 as a rotation center, the adjacent rotating bodies 14 are set about the respective driving shafts 20 as the rotation centers. Thus, the entire arrangement of the rotating bodies 14 can be changed in various ways. For example, as shown in FIG. 17, the massage head 2 can be refracted in an arc shape, and rotational stimulation by the pressing rod 15 can be applied to the skin surface with the massage head 2 along the curved surface of the body. it can.

  In this embodiment, the rotating shaft (rotating body) 14, the drive shaft 20 to which the passive gear 21 is fixed, and the gear shaft 23 to which the counter gear 22 is fixed are supported rotatably with respect to the movable frame 51 or the base frame 52. However, the drive shaft 20 and the gear shaft 23 can be fixed to the frames 51 and 52. In this case, the rotary table 14 and the passive gear 21 are connected and fixed, and the 14 and 21 are rotatably supported with respect to the drive shaft 20 fixed to the frames 51 and 52.

Seventh Example FIG. 18 shows a seventh example of the beauty equipment. The beauty device (massage device) according to the seventh embodiment is different from the sixth embodiment in that the massage unit 3 is provided with many rotating bodies 14 to make the massage head 2 longer. On the distal end side of the massage head 2, a male surface fastener 57a is sewn on the rear surface of the unit cover 55, and on the proximal end side of the massage head 2, a female side surface is formed on the front surface of the unit cover 55. Fasteners 57b are sewn.

  In the present embodiment, since the massage head 2 is elongated, rotational stimulation by the pressing rod 15 can be applied to the skin surface in a state where the massage head 2 is bent and wound around an arm, a leg, or the like. In addition, after wrapping the massage head 2 around the arm, leg, etc., the male and female hook-and-loop fasteners 57a and 57b are contacted and fixed, so that the massage head 2 can be mounted in an annular shape. Rotational stimulation by the pressing bar 15 can be applied to the skin surface in a free state.

  The female-side surface fastener 57 b can be bonded and fixed to the main body case 1. Further, by configuring the unit cover 55 with a loop pile fabric, the female side fastener 57 b can be eliminated and the male surface fastener 57 a can be directly fixed to the unit cover 55. Also in this example, the number of rotations of the turntable 14 was set to 60 rpm.
