Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 5 show an embodiment of the small massage machine 1 according to the present invention.
The "small size" mentioned here is a massage machine that can be held by hand and is intended to be used in a handheld state. Hereinafter, in this document, a detailed explanation will be given based on the front / back / top / bottom shown in FIG. 1 and the left / right shown in FIG.

As shown in FIG. 1, the small massage machine 1 includes a casing 2 and a massage body 3 provided so as to project downward on one end side (front side) of the casing 2.
The casing 2 is formed in a long shape made of resin or the like, and has a mechanical storage portion 4 (head portion) provided on the front side and a grip portion 5 extending rearward from the mechanical storage portion 4. Have. The massage body 3 described above is provided at the lower part of the mechanical storage portion 4. Further, the mechanical storage unit 4 houses a drive mechanism 6 for mainly applying vertical vibration to the massage body 3 and causing the treatment unit to perform a massage operation.

The grip portion 5 is elongated in a rod shape and gently curved upward, making it easy for the user to hold and hold. A switch 7 for driving and stopping the drive mechanism 6 is provided on the lower surface side of the grip portion 5 in the middle of the longitudinal direction.
The mechanical storage portion 4 is formed as a shape in which the vertical width and the horizontal width are larger than those of the grip portion 5. An opening 8 for the massage body 3 to project to the outside is provided on the lower surface of the mechanical storage portion 4. As shown in FIG. 1, around the opening 8, an annular edge 9 is formed so as to project downward from the mechanical storage portion 4.

The massage body 3 is connected to a drive mechanism 6 via a swing arm portion 10 (details will be described later), and the drive mechanism 6 causes the massage body 3 to reciprocate in the vertical direction.
The massage body 3 is made of rubber, resin, or the like having appropriate softness, and has a shape like a rectangular block with rounded corners. Further, the massage body 3 has a hollow inside and an upward open shape. The forming materials and shapes thereof are not particularly limited. For example, it is possible to appropriately change whether the inside of the head has a hollow structure or a solid structure, or only the surface has a structure in which a soft material is attached.

Next, the details of the drive mechanism 6 housed inside the mechanical storage part 4 will be described with reference to FIGS. 2 to 5.
As shown in FIGS. 2 and 3, the drive mechanism 6 includes a drive motor 11. The drive motor 11 is arranged so that the drive shaft of the drive motor 11 faces in the front-rear direction and projects forward.

The drive motor 11 rotates or stops by turning the switch 7 on and off, and is configured on the front side of the drive motor 11, that is, on the drive shaft side by meshing a worm gear (not shown) and a worm wheel 12. The reduced speed reducer 13 is connected. The deceleration output shaft 14 projects horizontally from the speed reducer 13 so as to project to the right.

A swing arm portion 10 is attached to the deceleration output shaft 14. Specifically, the swing arm portion 10 is a long crankshaft arranged along the vertical direction, and the upper end of the swing arm portion 10 is eccentrically rotatably attached to the deceleration output shaft 14. ..
As shown in FIG. 5, the middle portion of the swing arm portion 10 is bent inward along the outer shape of the drive motor 11. Further, as shown in FIG. 3, the lower end of the swing arm portion 10 is divided into a bifurcated shape in the front-rear direction, and the front legs 15 and the rear legs 16 facing in the horizontal direction are arranged at predetermined intervals in the front-rear direction. ing. The bifurcated portions (front leg 15 and rear leg 16) enter the internal space of the massage body 3 and are screwed to the massage body 3 itself.

As shown in FIG. 3, a rib member 17 formed so as to sandwich the swing arm portion 10 from the front and rear is formed in the vicinity of the upper end of the swing arm portion 10. The rib member 17 is provided so as to project from the right side wall of the speed reducer 13 to the right side. Even if the deceleration output shaft 14 rotates and the upper end of the swing arm portion 10 rotates eccentrically with respect to the deceleration output shaft 14, the rib member 17 suppresses the forward / backward movement of the swing arm portion 10. There is.

On the other hand, as shown in FIG. 5, the tether 18 is provided in a hanging shape from the lower surface of the speed reducer 13. The tether 18 is formed of an elastic body (hard rubber in the case of this embodiment) having a plate-like and strip-like shape.
The upper end of the tether 18 is formed so as to be bent horizontally to the left side, and this portion is screwed to the lower surface of the speed reducer 13. The lower end of the tether 18 is formed so as to be bent horizontally to the right side, enters the inside of the massage body 3 having an opening at the upper part and a cup shape, and is placed on the central bottom of the inside of the massage body 3 with the holding piece 20. It is designed to be installed after being suppressed.

The midway portion of the tether 18 is provided so as to penetrate the bifurcated gap portion 19 (the gap between the front leg 15 and the rear leg 16 forming the bifurcation) formed at the lower end of the swing arm portion 10. There is. The front-rear width of the gap 19 is slightly wider than the front-rear width of the middle portion of the tether 18, so that the tether 18 does not interfere with the swing arm portion 10.
Due to the elasticity of the tether 18, in other words, the elasticity in the direction orthogonal to the longitudinal direction of the tether 18 (waviness in the front-rear direction), the deceleration output shaft 14 rotates, and the upper end of the swing arm portion 10 is the deceleration output shaft 14. Even if the eccentric rotation is performed with respect to the above, the back-and-forth movement of the massage body 3 is suppressed, and the massage body 3 moves almost only up and down. However, the swell in the anteroposterior direction of the tether 18 is slightly present due to its elastic force, and the massage body 3 also reciprocates in the anteroposterior direction.

For this reason, the massage body 3 not only swings up and down as in a conventional massage machine, but also swings back and forth back and forth to give a comfortable massage to the user. It becomes possible. Further, since the tether 18 operates like a swell in the front-rear direction, it is possible to prevent an excessive load (stress) such as bending or bending from acting on only a part of the tether 18, and induce a failure for a long period of time. It is possible to configure a drive mechanism 6 that does not.

Further, since the massage body 3 can be moved back and forth due to the elasticity (bending) of the tether body 18 in the front-rear direction, the massage body 3 fits at a position along the curve of the user's shoulder. It will be easier. In this respect as well, it is possible to give a comfortable massage to the user.
As described above, the tethering body 18 is formed of a material having appropriate elasticity such as hard rubber or silicon and is erected between the massage body 3 and the speed reducer 13 side, so that the swing arm portion 10 When the eccentric drive is performed, an elastic force is applied to the swing arm portion 10 in the direction of pulling it back into the mechanical housing portion 4.

Next, the operation mode of the small massage machine 1 according to the present invention will be described.
First, when the switch 7 is turned on to operate the drive motor 11, the deceleration output shaft 14 decelerates and rotates via the speed reducer 13, and the deceleration output shaft 14 decelerates and rotates, so that the swing arm portion 10 The upper end will perform eccentric movement.
However, assuming that the deceleration output shaft 14 rotates due to the elastic force of the tether 18 connecting the lower surface of the speed reducer 13 and the massage body 3, and the upper end of the swing arm portion 10 rotates eccentrically with respect to the deceleration output shaft 14. However, the massage body 3 moves almost only up and down. However, due to the twisting of the tether 18 in the anteroposterior direction, the massage body 3 also moves back and forth slightly in the anteroposterior direction. Due to the twisting of the tether 18 in the anteroposterior direction, the massage body 3 is slightly movable in the anteroposterior direction. Therefore, the massage body 3 is easy to fit along the curve of the shoulder of the user, and a comfortable massage can be given.

When the massage body 3 swings in this way, the massage body 3 as a whole repeatedly moves back and forth with respect to the mechanical storage portion 4, and a rubbing motion that repeatedly reciprocates along the longitudinal direction of the grip portion 5. It will be in a state of being performed at the same time. Therefore, the user of this massage device can obtain a new feeling of massage that has never been seen before by such a combined operation. It should be noted that the embodiments disclosed this time are exemplary in all respects and are not considered to be restrictive. In particular, in the embodiments disclosed this time, matters not explicitly disclosed, such as operating conditions, various parameters, dimensions, weights, volumes of components, etc., do not deviate from the range normally implemented by those skilled in the art. However, a value that can be easily assumed by a person skilled in the art is adopted.

For example, the treatment head of the massage body 3 can be made into a ball shape or a shape in which the central portion is recessed like a saddle.
The small massage machine 1 of the present invention can be used not only on the shoulders but also on other parts of the body such as the neck, arms, and legs. You can use it in various ways, such as holding it in the optimal way, changing the posture of the device, leaving a part of it (mechanical storage part 4 etc.) on the floor or chair, or having someone else carry it. ..
