In a small massage device having a bar-shaped gripping part, it can be said that the bar-shaped gripping part is provided mainly for the purpose of enhancing the usability when shouldering.
However, for example, when gripping other than the shoulder such as a thigh or an arm, the rod-shaped gripping portion is hardly used. Rather, since the rod-like gripping portion is provided, the casing has limited locations other than the gripping portion, and is difficult to hold. In addition, the gripping portion protruding in a bar shape sometimes gets in the way.
For these reasons, in the small massage device disclosed in Patent Document 1, there is a problem that the places where massage can be performed (the place where the massage is performed) are limited to some extent.

  This invention is made | formed in view of the said situation, Comprising: It is not limited to a shoulder, It aims at providing the small massage apparatus which can perform the massage of the arbitrary places which a user desires easily.

In order to achieve the above object, the present invention has taken the following measures.
That is, a small massage apparatus according to the present invention includes a pair of massage bodies provided at a predetermined interval, and a drive unit that moves the pair of massage bodies close and separate so that sandwich massage can be performed on the treatment unit. And a casing that is formed so as to project the pair of massage bodies to the outside and cover the drive unit, and in which a grip portion is disposed in the vicinity of the drive unit.
With such a configuration, it can be used with the gripping part provided in the vicinity of the drive part being gripped, so it can be handled not only when the shoulder is squeezed but also when the part other than the shoulder such as a thigh or an arm is squeezed Becomes easy. That is, the massage is not limited to the shoulder, and can easily be performed at an arbitrary location desired by the user.

The pair of massage bodies may be formed in a spatula shape having opposing flat surfaces.
By doing in this way, the surface pressure at the time of the acupressure by each massage body will be moderated moderately, and a user will not need to receive a stimulating acupressure feeling. This is particularly suitable when performing massage on a thigh or an arm.
One of the pair of massage bodies is a stationary massage body that is fixed in position without being driven by the drive unit, and the other of the pair of massage bodies is moved closer to and away from the stationary massage body by driving the drive unit. The movable massage body and / or the stationary massage body are elastically deformable along the approaching / separating direction of the movable massage body, and the grip portion is formed on the side close to the stationary massage body. It is preferable that

In this way, the drive unit does not drive both massage bodies in the direction of relative proximity and separation, but has a structure that drives only one massage body (movable massage body), thus simplifying the structure, reducing weight, and reducing costs. What is necessary is just to plan.
In this case, the movable massaging body and / or the stationary massaging body should be structurally elastic so as to prevent stimulating acupressure from the user. Is reasonable from an operational point of view.
In addition, the movable massage body gives a massage operation (proximity separation / reaction) to the user, whereas the stationary massage body has an effect of supporting this massage operation. Therefore, if the grip portion is provided in an arrangement close to the stationary massage body, the massage treatment can be performed stably.

The said drive part is good also as what can provide a vibration to a stationary massage body.
By doing in this way, vibration is added to the massage massage by both massage bodies being relatively close to each other, and a comfortable massage feeling is obtained.
The casing preferably has a stationary surface formed on a side opposite to a direction in which the pair of massage bodies protrudes.
By doing in this way, it becomes possible to place the floor in the direction in which the stationary surface faces downward and the pair of massage bodies protrude upward.

The grip part provided in the casing may have a grip bar installed in parallel with a direction in which the pair of massage bodies protrudes.
Thus, if the gripping part is formed by a gripping bar, it is easy to hold and can be a compact gripping part that does not protrude from the casing.
It is preferable that a squeezing width adjusting mechanism for adjusting a distance between the pair of massage bodies is provided in the casing.
By doing so, massages at various locations such as shoulders, thighs and arms can be appropriately performed. Moreover, the versatility with respect to many users from which a body shape and sex differ can be given.

  The small massage apparatus according to the present invention can easily perform massage at an arbitrary location desired by the user.

This small massage apparatus 1 is provided with a pair of massage bodies 5 and 6 projecting from a casing 2 that is relatively small enough to be grasped by a user in a state of being parallel to each other at a predetermined interval. It consists of.
As illustrated in FIG. 1, the small massage apparatus 1 is configured such that the casing 2 is gripped by hand so that the massage bodies 5 and 6 are in a downward projecting state, and the thighs are lifted from above by the massage bodies 5 and 6. It can be used in a state where it is sandwiched and massaged.

Alternatively, as illustrated in FIG. 7, the small massage apparatus 1 is placed on the floor with the casing 2 turned upside down so that the massage bodies 5 and 6 are in an upwardly projecting state. It can also be used for massaging massage by setting the thighs to be sandwiched from below.
In addition to those illustrated in FIG. 1 and FIG. 7, the small massage device 1 according to the present invention is a place desired by the user, such as a calf, an arm, and, of course, a shoulder. It is characterized by the fact that it is possible to massage with massage.

In the following description, for the sake of convenience of explanation, the left-right direction of the sheet of FIG. 3 is the left-right direction of the apparatus, the up-down direction of the sheet of FIG. These directions are only for explaining the orientation and structure of each member in a correlated manner, and do not limit the directionality in use.
The casing 2 is formed as a rectangular box (thin box in the front-rear direction), and has large chamfers at the four corners. As shown in FIGS. 2-5, with respect to such a casing 2, both the massage bodies 5 and 6 are provided so that it may protrude outward (downward) from the lower long side.

On the upper long side of the casing 2, that is, on the opposite side to the direction in which the massage bodies 5 and 6 protrude, a stationary surface that can be used in a floor-mounted state as shown in FIG. 2a is formed. In the case of the present embodiment, the stationary surface 2a is formed as a surface with a gently curved outer bulge, but does not prevent the small massage device 1 from being placed on the floor.
In the casing 2, the positions at which the massage bodies 5 and 6 protrude are arranged so as to be biased toward the right short side from the center in the left-right direction (longitudinal direction) of the casing 2. A finger ring portion 7 penetrating in the front-rear direction is formed on the left short side of the casing 2. This finger ring portion 7 is formed with an opening size enough to insert four fingers other than the thumb of one hand or slightly larger than that.

The outer frame portion (the left end of the casing 2) forming the finger ring portion 7 forms a grip bar 8 having a thickness suitable for gripping with a palm. The grip bar 8 is provided in such a manner that the longitudinal direction of the grip bar 8 is substantially parallel to the direction in which the massage bodies 5 and 6 protrude from the casing 2 (vertical direction in FIG. 3). That is, unlike the conventional small massage device, the small massage device 1 is not provided with a grip portion extending in a rod shape with respect to the casing 2.
Therefore, this casing 2 can grasp the casing 2 from the left and right while grasping the grip bar 8 or putting the four fingers excluding the thumb into the finger ring 7. For these reasons, the finger ring portion 7 and the grip bar 8 form the grip portion 9 of the casing 2. Needless to say, while holding the grip portion 9 with one hand, the casing 2 may be held with both hands by attaching the other hand to the right side of the casing 2 (see FIG. 1). Yes.

As shown in FIG. 6, the drive unit 10 and the squeezing width adjusting mechanism 11 are accommodated in the casing 2, but the finger ring portion 7 of the grip portion 9 faces the inner surface of the ring and the drive portion. A switch 12 is provided to switch 10 on and off. A power cord 13 for supplying power to the drive unit 10 is extended and connected from the lower end of the grip bar 8 in the grip unit 9.
The drive unit 10 is for causing the massage bodies 5 and 6 to repeatedly move toward and away from each other, and to apply vibration to one of the massage bodies 5 at the same time as causing the movement to move toward and away from each other. is there.

In the present embodiment, the driving unit 10 drives only the massage body 6 on one side (right side in FIG. 3), and causes the proximity and separation operation toward the other massage body 5 (left side in FIG. 3). It has a structure. Therefore, hereinafter, the massage body 5 that does not receive the drive of the relative proximity / separation by the drive unit 10 is referred to as a “stationary massage body”, and the massage body 6 that receives the drive of the proximity massage body 5 by the drive unit 10 is “movable massage” Called "body".
Further, only the stationary massage body 5 is given vibration by the driving unit 10.

The drive unit 10 includes a two-axis type motor 20 having a motor shaft protruding in opposite directions, a first output conversion unit 21 and a second output conversion unit that are driven by different motor shafts of the motor 20. 22, a link mechanism 23 that transmits the output of the first output conversion unit 21 to the movable massage body 6, and a transmission unit 24 that transmits the output of the second output conversion unit 22 to the stationary massage body 5.
The motor 20 is disposed on the upper part of the stationary massage body 5. When the small massage apparatus 1 is used with the stationary massage body 5 protruding downward, the load of the motor 20 pushes the stationary massage body 5 directly below. It comes to load in the state. That is, the position of the stationary massage body 5 becomes the load point (the position of the center of gravity in the front-rear and left-right directions) as a whole of the small massage apparatus 1 by the load of the motor 20.

In other words, the stationary massage body 5 acts as a fulcrum position for receiving the movement of the movable massage body 6 that repeats the relative approaching / separating operation when performing massage massage. 1 mounting stability will be improved.
In addition, since the motor 20 is disposed at the upper position with respect to the casing 2, when the small massage device 1 (casing 2) is turned upside down and placed on the floor by the installation surface 2a, the load of the motor 20 is increased. The effect | action which raises mounting stability as this small massage apparatus 1 is show | played.

The first output conversion unit 21 has a structure in which power is taken out from a worm gear attached to one motor shaft of the motor 20 as a decelerated rotation of the worm wheel, and the eccentric wheel 27 is rotated from the worm wheel.
The link mechanism 23 holds the upper end portion of the movable massage body 6 so as to be swingable by a swing support point 28 whose axis is directed in the front-rear direction, and the upper end portion of the movable massage body 6 is located above the swing support point 28. A drive arm 31 of an arm holder 30 that is rotatably fitted to an eccentric wheel 27 is connected to an input end portion 29 that is provided so as to extend to the center.

With this link structure, the eccentric wheel 27 is decelerated by driving the motor 20 to cause eccentric rotation, and the arm holder 30 slidably fitted on the eccentric wheel 27 and the drive connected to the arm holder 30 are connected. The arm 31 reciprocates in the left-right direction. As a result, the drive arm 31 imparts rocking drive to the input end 29 of the movable massage body 6, and the movable massage body 6 moves toward the lower end portion via the rocking fulcrum 28. Oscillation with large amplitude occurs.
The second output conversion unit 22 is provided to project in the radial direction from a vibration case 34 provided to cause the eccentric weight attached to the other motor shaft of the motor 20 to rotate at a high speed and enclose the eccentric weight. In addition, the vibration is transmitted to the stationary massage body 5 via the first transmission body 35 and the second transmission body 36 that is bent at the tip of the first transmission body 35 to be L-shaped.

The drive unit 10 can be switched on and off by operating the switch 12 provided on the gripping unit 9 as described above. It is preferable that a timer circuit is incorporated so that the power supply circuit is automatically shut off.
On the other hand, the squeezing width adjusting mechanism 11 is for allowing one or both of the pair of massage bodies 5 and 6 to adjust the distance between the massage bodies 5 and 6. This squeezing width adjusting mechanism 11 is provided for the second transmission body 36 of the drive unit 10 described above.

Specifically, the second transmission body 36 has a screw shaft 41 whose axial center is directed in the left-right direction with respect to a pair of left and right bearing portions 40, 40 provided at predetermined intervals in the left-right direction at the lower part in the casing 2. A slider 42 is provided in a state of being rotatably held and screwed to the screw shaft 41 so as to be movable left and right, and the stationary massage body 5 is supported in a suspended manner via the slider 42. ing.
An adjustment knob 43 is coupled to the left end of the screw shaft 41 so as to be integrally rotatable. A part of the outer peripheral surface of the adjustment knob 43 is a casing as shown in FIGS. 2 is exposed on the lower surface. Accordingly, the adjustment knob 43 exposed from the casing 2 can be rotated by hooking a finger on the adjustment knob 43.

Both the stationary massage body 5 and the movable massage body 6 are formed in a spatula shape having substantially flat surfaces as surfaces facing each other. These massage bodies 5 and 6 are covered with an outer skin formed of soft rubber, soft resin, or the like, and are formed so that cushioning properties and touch feeling are suitable. In addition, the stationary massage body 5 and the movable massage body 6 are formed so as to be elastically deformable (warp back) along the left-right direction.
Next, the usage aspect of the small massage apparatus 1 which concerns on this invention is demonstrated.
While holding the grip portion 9 of the casing 2 by hand, the thighs, arms, shoulders, etc. are sandwiched between the massage bodies 5 and 6 (see FIG. 1), or the casing 2 is placed upside down and placed on the floor. The thighs and arms are sandwiched between the massage bodies 5 and 6 (see FIG. 7).

At this time, when the contact surface pressure to the massaged part (skin surface) by both massage bodies 5 and 6 is too low, on the contrary, too high, or cannot be pinched in the first place, the adjustment of the itch width adjusting mechanism 11 is performed. The knob 43 may be rotated to adjust the mutual distance between the massage bodies 5 and 6.
In this state, the switch 12 is turned on to drive the drive unit 10. Since the switch 12 is provided facing the inner surface of the finger ring portion 7 in the grip portion 9, this switch operation can be performed easily and quickly with the gripping hand while gripping the grip portion 9.

By this switch operation, the movable massage body 6 starts swinging toward and away from the stationary massage body 5 and the stationary massage body 5 starts to vibrate. Thereby, the user can receive a comfortable massage in which massage massage and vibration are combined. Since vibration has an effect of relieving pinpoint acupressure when grasping by massaging massage, no discomfort occurs even if the massage time continues.
Moreover, since both the massage bodies 5 and 6 are made into a flat spatula shape and the movable massage body 6 is formed with elasticity, a stimulating acupressure feeling is further prevented. The pleasure of is enhanced.

In the present embodiment, the movable massage body 6 imparts a massage operation (proximity separation / separation) to the user, whereas the stationary massage body 5 has an effect of supporting this massage operation. Therefore, if the holding part 9 is provided in the arrangement close to the stationary massage body 5, the small massage apparatus 1 can be stably held.
As is clear from the above description, the small massage device 1 according to the present invention can easily perform massage at an arbitrary location desired by the user.
The present invention is not limited to the above-described embodiment, and can be appropriately changed according to the embodiment.

  For example, the shapes of the massage bodies 5 and 6 are not limited to the spatula shape, and various shapes can be adopted. Attachments with various outer shapes (those with different finger pressure sensations) may be detachably provided for replacement or external fitting.
