Description

  The present invention relates to a handy type massager that is provided with a head swinging tool and that can effectively acupressure the affected part with its tip.

  Conventionally, the affected part such as the shoulder and the back is rubbed with a fingertip to eliminate stiffness and to apply acupressure. In addition, a vibrator is provided in which a vibrator is built in a rod-shaped case and the stiffness is solved by this vibration. This vibrator generates vibration by rotating a weight attached to the motor in a cantilevered state.

  There is a problem that if the fingertip as described above is used to manually rub or push the affected area, the fingertip becomes tired or hurts immediately and does not last long. In addition, there are many requests for stimulation that is pushed with a finger even if it is performed on a machine.

  This device is intended to solve the above-mentioned problems and provide a massager that can mechanically apply stimulation such as finger pressure.

  For this reason, in this device, a motor is housed in a long and narrow case so that the rotating shaft is directed in the longitudinal direction of the case, and a converter that converts rotational motion into reciprocating motion is attached to the rotating shaft. One end of the converter is locked to the eccentric shaft of the attached rotating disk so that the rotating shaft of the rotating disk is orthogonal to the rotating shaft via a gear train. A reciprocating rod is provided, and a swinging tool is rotatably mounted inside the front of the case with a rotating shaft orthogonal to the longitudinal direction of the case, and the swinging tool protrudes forward of the swinging The case is provided with a hole, and a side opposite to the protruding side of the swinging tool across the rotation shaft is attached to the other end of the reciprocating rod. A shiatsu massage device is provided. The motor is connected to a battery serving as a power source and a switch for turning on / off the motor.

  The rotating motion of the rotating disk attached to the rotating shaft of the motor is converted into the reciprocating motion of a reciprocating rod whose one end is locked to the eccentric shaft of the rotating disk. The reciprocating motion of the reciprocating rod causes the head swinger to perform a pivoting motion with the pivot shaft as the pivot center. The swinging front portion of the swinging tool performs a reciprocating motion that repeatedly goes out and in and out of the hole of the case. Therefore, by holding the case with your hand and applying the area around the hole of the case to the part you want to massage, you can continue to give as much stimulation as you like, and this is done mechanically. I don't get tired.

  In addition, it is also possible to give a stimulus such as hitting the ton of the case by applying the area around the hole of the case to a deeply affected part such as an ear canal.

  Next, the invention of claim 2 is that the other end of the reciprocating rod and the protruding side of the swinging device are opposite to the side opposite to the rotation shaft, or two reciprocating rods are provided. And a coil spring is interposed between the divided parts. In any of these configurations, the coil spring is compressed in the direction in which the reciprocating rod is pushed, so that the front part of the swinging tool is softly brought into contact with the affected part and then pushed with a predetermined force. When the front part of the swing moves away from the affected part of the body, the coil spring is stretched and quickly retracted, and the contact with the affected part has an effect of starting softly, and also having an effect of sharpening the pushing and releasing.

  Further, in this device, a vibration generating part composed of an electromagnetic coil and a vibrator housed in a reciprocating vibration is housed in an elongated case so that the vibrator faces the longitudinal direction of the case. In addition, a swinging tool is rotatably attached to the inside of the front of the case with a rotary shaft orthogonal to the longitudinal direction of the case, and the swinging tool protrudes forward of the swinging to the case. A shiatsu massager is provided, wherein a hole is provided, and a side of the swinging device that is opposite to the protruding side across the rotation shaft is attached to one end of the vibrator. To do. An oscillation circuit for supplying an alternating current, a battery as a power source, and a switch for turning on / off the motor are connected to the heavy magnetic coil.

  When the power of the acupressure massage machine is turned on, the oscillation circuit oscillates to generate an alternating current, which is applied to the electromagnetic coil to generate a magnetic field line, and the magnetic field line causes a reciprocating vibration in the vibrator. Unlike the motor, the reciprocating motion of the vibrator is relatively quiet because it does not produce a rotating sound. The reciprocating motion of the vibrator exhibits the same effect as the reciprocating motion of the reciprocating rod of claim 1 described above, and causes the head swinger to perform a rotational motion about the rotational axis. As a result, the swinging front part of the swinging tool performs a reciprocating motion that repeatedly moves in and out of the hole of the case. Therefore, just hold the case with your hand and apply the area around the hole to the body part you want to massage. The fact that nothing happens is the same effect as that of the first aspect of the invention.

  The vibrator may be a permanent magnet. Although it is possible to configure the vibrator with an electromagnet, there is an advantage that an unstable mechanism such as a contact point or a brush for power supply is not necessary if the permanent magnet is a permanent magnet. In addition, the number of sets of electromagnetic coils and vibrators that constitute one vibration generating unit can be a plurality of sets.

  In order to expose a body that directly or indirectly touches the case to an alternating magnetic field generated from the electromagnetic coil, the case may be configured to transmit magnetic lines of force at least in part. I can do it. The magnetic field generated from the alternating magnetic field generated from the electromagnetic coil and the vibrator performing reciprocal vibrations passes through the case and contacts the body part, and the effect of magnetic therapy is given to the body part. A common plastic material can be used for the case.

  In the meaning of this magnetic treatment, a permanent magnet can be attached to the protruding side of the head swing device of the first aspect.

  The one end of the vibrator and the protruding side of the swinging tool are separated from the opposite side across the rotation shaft, or the vibrator is divided into two parts. A coil spring may be interposed therebetween. As in the case of claim 2 described above, the swinging front part of the swinging tool will be pressed with a predetermined force after softly contacting the affected body part, and when the swinging front part is separated from the affected body part The coil spring is stretched and quickly retracted, and the contact with the affected area has the effect of starting softly and the effect of being able to give sharpness to pushing and releasing.

  In addition, both the device of claim 1 and the device of claim 3 can be configured such that a cover made of a flexible material is hung at least on the hole. The cover can be made of a flexible material such as a rubber material, a plastic material, or a cloth material. The cover softens the body and provides an effective massage action. Or you may comprise so that the whole case may be covered with a cover. It can be configured to be effective in waterproofing. The cover may be detachable from the case so that the cover can be replaced with a favorite cover. As an example, a configuration like the cover C in FIG. 1 is raised.

  According to this device, it has succeeded in providing the handy type massage device which can give a stimulus like acupressure mechanically effectively with respect to an affected part.

  2 is an exploded side view of Example 1. FIG.   (A) (B) is a side view of a reciprocating cage.   It is explanatory drawing showing the assembly | attachment state of a crown gear and a reciprocating rod.   It is sectional explanatory drawing of the linear motor of Example 2. FIG.   It is a block diagram of a drive part.

  1 to 4 show an acupressure massager according to Embodiment 1 of the present invention. A hole 13 is opened on one side of the distal end portion of the elongated case 1 to be brought into contact with a body affected part such as a shoulder or a back so that the swinging tool 2 protruding from the hole 13 can reciprocate. It is attached inside the case 1 (FIG. 1).

  The case 1 is provided with a connection portion 10 to which a controller / battery box (not shown) can be attached. The motor 5 is accommodated in the area ahead of the connecting portion 10. A pinion gear 50 is attached to the shaft of the motor 5, and the crown gear 4 is housed in mesh with the pinion gear 50 (FIG. 1). Note that the case 1 is formed by being divided into two vertically divided parts, and the casing is assembled with the screw holes 12 together. Moreover, the lead wire 51 of the motor 5 is pulled out from the through hole 11 opened in the wall surface of the connecting portion 10 and connected to the controller / battery box described above. The battery box contains a dry battery. The controller also includes a slider (not shown) for controlling the number of rotations of the motor 5, that is, for controlling the number of rotations of the swinging portion as will be described later.

  The pinion gear 50 has a special shape. That is, an eccentric ring 41 is formed around the rotation shaft 40 so as to shift the axis (FIG. 3). On the other hand, a box 30 is provided at the rear end portion of the reciprocating rod 3 having a shaft hole 32 opened at the tip portion, and a vertically long circular opening portion 31 is provided on the side surface portion (see FIG. 2 (A)). The box body 30 is fitted in the eccentric ring 41, and the reciprocating rod 3 and the crown gear 4 are assembled so that the rotation shaft (pin) 40 is accommodated in the opening 31.

  Therefore, when the crown gear 4 rotates with the rotation of the motor 5, the eccentric ring 41 rotates around the rotation shaft 40, and the box body 30 fitted in this rotates reciprocally. At this time, the opening portion 31 and the rotating shaft 40 accommodated therein serve as a guide to reciprocate the box 30, that is, the reciprocating rod 3 without shaking.

  A swing tool 2 is attached to the tip of the case 1. The head swinging tool 2 is rotatably attached to the turning shaft of the case 1 through a shaft hole 20. Further, another shaft hole 21 of the swinging tool 2 and a shaft hole 32 at the tip of the reciprocating rod 3 are assembled so as to be rotatable with respect to each other with a rotation shaft. The other shaft hole 21 is a hole provided on the opposite side of the shaft hole 20 which is the rotation shaft from the protruding side of the swinging tool 2.

  Therefore, when the reciprocating rod 3 starts to reciprocate, the rotation shaft of the shaft hole 32 pushes or pulls the shaft hole 21 of the swinging tool 2, but the swinging tool 2 rotates the case 1 through the shaft hole 20. Since the swinging tool 2 is pivotably attached to the moving shaft, the swinging tool 2 performs a swinging motion around the shaft hole 20 (FIG. 1). Therefore, when the swinging tool 2 swings to the right in FIG. 1, it jumps out of the case from the hole 13 of the case 1. As a result, if the part of the hole 13 of the case 1 is in contact with the affected part of the body such as the shoulder or back, the affected part of the body is subjected to stimulation such as acupressure by the reciprocating head swinging tool 2. It is possible to give a massage effect with an unprecedented feeling.

  As shown in FIG. 2B, the reciprocating rod 3 of FIG. 2A can be divided into two reciprocating rods 33 and 34, and a coil spring 35 can be interposed between them. According to this, since the coil spring 35 is compressed in the direction in which the reciprocating rods 33 and 34 are pressed, the swinging front part of the swinging tool 2 is softly contacted with the affected part of the body and then pressed with a predetermined force, and When the front part of the head swings away from the affected part of the body, the coil spring 35 is stretched and quickly retracted, so that the effect of starting the contact with the affected part softly and the pressing and releasing can be sharpened. The effect comes out.

  The same action can be realized even if the coil spring 35 is configured to be passed over the shaft hole 32 of the reciprocating rod 3 and the shaft hole 21 of the swinging tool 2 shown in FIG.

  4 and 5 relate to Embodiment 2 of the present invention. The configuration of the elongated case 1 that makes contact with the affected part of the body, such as the shoulder and back, is similar to that of the first embodiment. However, instead of the motor 5 that rotates the shaft, the shaft 64 reciprocates linearly. The feature is that a motor 6 is incorporated (FIG. 3).

  This linear motor 6 covers the periphery of a cylindrical motor container composed of a magnetically permeable peripheral wall portion 61 and side wall portions 62, 62 on both sides with a permeable, elongate case 60 that makes contact with a body affected part such as a shoulder or a back. It is a thing. The side wall portions 62 and 62 on both sides are each provided with a bearing 63 through which a shaft 64 passes at the center thereof, and magnetic springs 9 and 90 to be described later are fixed inside. A yoke 7 having a central hole through which the shaft 64 passes is formed inside the central portion of the peripheral wall 61 and an electromagnetic coil 70 wound around the outer periphery thereof is fixed at the outer peripheral portion of the electromagnetic coil 70. Yes. Further, between the electromagnetic coil 70 and the magnetic springs 9 and 90 on both sides thereof, permanent magnets 8 and 80 are fixed to the shaft 64 that passes through the central holes of the permanent magnets 8 and 80. In this embodiment, the permanent magnets 8 and 80 are arranged such that the side facing the yoke 7 is the S pole. In this embodiment, the magnetic springs 9 and 90 are arranged in such a manner that the side toward the permanent magnets 8 and 80 is an N pole. The shaft 64 is connected to another shaft 65 via a coil spring 66 on the right side of FIG. This is configured to obtain the same action as the coil spring 35 of FIG.

  As shown in the block diagram of FIG. 5, the drive unit of the linear motor 6 includes an oscillating unit 73 that generates low-frequency vibration for the purpose of shiatsu massage, and a control unit 71 at the output end of the oscillating unit 73. The connected electromagnetic coil 70, a charging unit 74 that supplies power to the electromagnetic coil 70, and a power supply unit 72 that is connected to the charging unit 74 via a control unit 71 are configured. The control unit 71 includes an operation unit for setting an oscillation frequency (not shown) and a display unit for displaying the ON / OFF state of the power source, the oscillation frequency, and the like. In this embodiment, the power supply unit 72 is an adapter connected to a household power source. A power cord (not shown) is connected to the power supply unit 72. In addition, regarding the setting of the oscillation frequency, this embodiment can be set to the number of acupressures that feels comfortable to the body. The number of acupressure felt to be comfortable varies depending on the individual, varies depending on the body part, and varies depending on the mood of each occasion, and may be adjusted to be optimal.

  Now, when a switch (not shown) is turned on, that is, when the control unit 71 is turned on, the oscillating unit 73 generates an alternating current, which is supplied to the electromagnetic coil 70, and the electromagnetic coil 70 generates a magnetic force line M passing through the yoke 7. To do. Magnetic poles N and S appear alternately on both sides of the yoke 7. The situation at this time will be described with reference to FIG. 4. The yoke 7 on the magnetic pole N side and the south pole of the permanent magnet 8 attract each other, and the yoke 7 on the magnetic pole S side and the south pole of the permanent magnet 80. And the shaft 65, that is, the shaft 65 via the coil spring 66 moves in the right direction (arrow direction) in FIG. However, since the magnetic pole of the yoke 7 of the electromagnetic coil 70 reverses at this next moment, the shaft 65 moves to the left in FIG. In this way, vibration is generated in the shaft 65. At this time, the permanent magnets 8 and 80 increase the inertial force by their own weight. Whether the shaft 65 moves rightward or leftward, the N pole of the permanent magnet 8 and the N pole of the magnetic spring 9 repel each other, and the N pole of the permanent magnet 80 and the magnetic force Since the N pole of the spring 90 repels, it does not happen that the shaft 65 swings too much from side to side. In this way, the linear motor 6 reciprocates, and this reciprocation appears as the reciprocation of the swinging tool 2 connected to the shaft 65. Therefore, the affected part of the body is subjected to stimulation such as finger pressure by the reciprocating head shaker 2 and can provide a massage effect with an unprecedented sensation.

  Incidentally, as described above, the linear motor 6 includes the magnetically permeable peripheral wall portion 61 and the case 60. As a result, the magnetic lines of force M generated inside the linear motor 6 are transmitted through the peripheral wall 61 and the case 60 and affect the affected part of the body that touches the case 60 (blood of the body exposed to an alternating magnetic field). Has a positive impact on the flow).

  In addition to the acupressure operation, the massaging device of the massage device of the present invention can be used or configured for the purpose of rubbing (or scratching or hitting) the skin surface such as the back. The head swinger may be configured to perform a more complicated motion combining two reciprocating motions of vertical and horizontal.
