Description

  The present invention relates to a massage device for pressing a part or the whole of a body to improve blood flow, loosening muscles or correcting bones to make them healthy.

  Conventionally, a chair type massage device that presses a part or the whole of a body with a roller has been used. Patent applications have been filed for chair-type massage devices (see, for example, Patent Documents 1 and 2).

  However, the chair-type massage device is large enough for a human to sit on, so the material cost is high and the manufacturing cost is high. In addition, the chair-type massage device has an electric cost because it moves the roller by an electric motor and presses the body. On the other hand, there is a massage device that is held by hand and presses the protrusions or the like on a part or the whole of the body and does not use electricity bills, but requires strong arm strength and cannot be used by those with weak arm strength.

A fourth sphere (second intervention member) 32 is placed between the sphere 28 and the second sphere 14 on the slot 20.

  The first spherical body 12 and the second spherical body 14 are elastic bodies having a rubber body 34 and a hollow portion 36. As the first spherical body 12 and the second spherical body 14, a soft baseball ball having a rubber body and a hollow portion may be used. The first spherical body 12 and the second spherical body 14 do not need to have the hollow portion 36 as long as they are elastic bodies.

  The outer peripheral surfaces of the first spherical body 12 and the second spherical body 14 are covered with a bag (sliding member) 38 made of a resin such as polyethylene having a smooth surface. It is desirable that the surface of the bag 38 has a coefficient of static friction such that the clothes worn by the body or the skin of the body slip. For example, it is desirable that the coefficient of static friction is 0.01 to 0.2.

  The base 18 is not deformed or broken even when the body is placed on the first spherical body 12 and the second spherical body 14 and the body load is received via the first spherical body 12 and the second spherical body 14. It is made of metal or resin. Rails 40 are provided on both sides of the base 18 so that the first spherical body 12, the second spherical body 14, the third spherical body 30 and the fourth spherical body 32 do not roll out.

  The first upright portion 24 and the second upright portion 28 place the body on the first spherical body 12 and the second spherical body 14 so that the first spherical body 12 and the second spherical body 14 are separated from each other. A force is applied to the first sphere 12 and the second sphere 14 in the direction, and the force is applied to the first sphere 12 and the second sphere 14 via the third sphere 30 or the fourth sphere 32. Yes. FIG. 1 shows an embodiment in which the first standing portion 24 and the second standing portion 28 are configured integrally with the base 18. The base 18, the first standing portion 24, and the second standing portion 28 are formed by, for example, bending both ends of one long member in a right angle direction.

  The outer peripheral surfaces of the third spherical body 30 and the fourth spherical body 32 are frictional forces between the first spherical body 12 or the second spherical body 14, the slot 20, and the first standing portion 24 or the second standing portion 28.

As the third spherical body 30 and the fourth spherical body 32, a hard baseball ball in which a thread is wound around a cork or rubber core, covered with a leather, and stitched may be used.

  The effects of pressing the back side of the lumbar part of the body using the massage device 10 having the above configuration will be described below.

  First, as shown in FIG. 2, the massage device 10 is placed on the bed 44 by bringing the lower surface 16 of the base 18 into contact with the upper surface of the bed 44. Next, the person pressing his / her body lies on his / her back and lowers the back side of the waist 46 of the body onto the first spherical body 12 and the second spherical body 14.

  As shown in FIG. 3, the back side of the waist 46 of the body abuts on the first spherical body 12 and the second spherical body 14. At this time, the back side central portion 48 of the waist 46 enters from between the first spherical body 12 and the second spherical body 14, and the waist portion 46 pushes the first spherical body 12 and the second spherical body 14 in an oblique direction. Pressure P is applied. When the first spherical body 12 and the second spherical body 14 are applied with the pressing force P, the first spherical body 12 and the second spherical body 14 move in the X-axis negative direction or the positive direction, and the first spherical body 12 12 and the second spherical body 14 are separated from each other. When the first spherical body 12 and the second spherical body 14 are separated from each other, the impact received by the waist 46 from the first spherical body 12 and the second spherical body 14 is reduced.

The first spherical member 12 and the second spherical body which has moved in the X-axis negative direction or the positive direction 14 adds a pressing force P _X in the X-axis negative direction or the positive direction to the third spherical body 30 or the fourth spherical body 32 . Third spheres 30 or fourth spherical body 32 which is added to the pressing force P _X in the X-axis negative direction or the positive direction from the first spherical body 12 or the second spherical member 14, the first spherical member 12 or the second spherical Together with the body 14, it moves in the X-axis negative direction or the positive direction, and comes into contact with the first standing part 24 or the second standing part 28 and stops.

  When the third spherical body 30 and the fourth spherical body 32 are stopped, the movement of the first spherical body 12 and the second spherical body 14 is also stopped. When the first spherical body 12, the second spherical body 14, the third spherical body 30 and the fourth spherical body 32 are stopped, the waist 46 is placed on the first spherical body 12 and the second spherical body 14.

When the waist 46 is placed on the first spherical body 12 and the second spherical body 14, by the weight of the body, the same direction of the pressing force P ₁ is the first spherical body 12 and the second and P shown in FIG. 3 It acts on the spherical bodies 14, acting pressing force P _X1 in the same direction as the P _X shown in FIG. 3 from the first spherical body 12 and the second spherical member 14 to the third spherical body 30 or the fourth spherical body 32, FIG. A pressing force P _Z1 in the same direction as P _Z shown in FIG. 3 acts on the base 18 from the first spherical body 12 and the second spherical body 14.

Therefore, as shown in FIG. 4, the reaction force _{N Z} against the pressing force _{P Z1} acts from the base 18 to the first spherical body 12 and the second spherical member 14, the reaction force _{N X} against the pressing force _{P X1} is a The reaction force N against the pressing force P ₁ acts on the first spherical body 12 or the second spherical body 14 from the trispherical body 30 and the fourth spherical body 32, and is applied from the first spherical body 12 and the second spherical body 14 to the waist 46. Works.

Each reaction force N is the resultant force of the reaction force N _Z of the reaction force N _X and Z-axis direction of the X-axis direction. Moreover, the surface of the bag 38 is a sliding surface. For this reason, the friction force in the tangential T direction does not act on the bag 38, and the direction of each reaction force N is a direction perpendicular to the tangent T between the waist 46 and the first spherical body 12 or the second spherical body 14. It is.

  Therefore, the two reaction forces N always act in an oblique direction with respect to the X-axis direction and the Z-axis direction, and act toward a point near the center of the waist portion 46 on the center line C of the waist portion 46. Thereby, the waist | hip | lumbar part 46 is fixed in the stable state and does not shift | deviate to a X-axis direction.

  Further, since the two reaction forces N act toward the point on the center line C of the waist 46, the directions of the two reaction forces N are line symmetric with the center line C as the axis of symmetry, and the two reaction forces Are the same size. Thereby, reaction force N of the same direction and the same magnitude acts on the waist 46 from the left and right sides of the body, and for example, the distortion of the spine in the left-right direction can be corrected.

  According to the massage device 10 of the present invention, the first standing portion 24 and the second standing portion 28 are formed in the vicinity of the end portion of the base 18, the slot 20 is provided in the base 18, Since the first spherical body 12, the second spherical body 14, the third spherical body 30, and the fourth spherical body 32 are placed and configured, the manufacturing cost can be reduced unlike the chair type massage device. Moreover, since it is not electric, it does not cost electricity.

The rack 224 is covered with a cover 282 so that a finger does not enter the slot 232 and be injured. Inner races 236 of the two ball bearings 234 are fixed to the base 208 via spacers 238. In order for the rack 224 to slide smoothly in the X-axis direction, the tooth surface should be meshed as a gear, and the relative positional accuracy between the rack 224 and the pinion 226 must be maintained. In the present invention, a guide (one inner side surface 242 and another inner side surface 243) is provided inside the rack 224, and the guide slides across two shafts that restrict displacement of the rack 224 in the Y-axis direction. is there. The gap between the shaft and the guide is kept at an optimal minimum. In the present invention, a bearing (two ball bearings 234) is used as the shaft in order to make the sliding more smooth. 10 to 12 show a state in which the outer race 240 of the two ball bearings 234 and the inner surface 242 of one of the slots 232 are in contact with each other, there are cases in which the inner surface 243 contacts with another inner surface 243. The tooth tip or the tooth bottom of the tooth portion 230 of the rack 224 does not hit the tooth bottom or the tooth tip of the tooth portion 250 of the pinion 226.

  As shown in FIG. 11, a ball bearing 244 is supported on a base 208, an outer race 246 of the ball bearing 244 is fixed to the base 208, and an inner race 248 of the ball bearing 244 is fixed to a pinion 226. It is preferable that the ball bearing 244 is a deep groove ball bearing capable of applying both a radial load and an axial load. The pinion 226 has a circular tooth portion 250 formed on the outer periphery. Near the both ends of the pinion 226 in the X-axis direction, two rod-like stoppers (locking means) 252 that can bite into the tooth portion 250 of the pinion 226 are arranged. The stopper 252 is supported by a guide 254 fixed to the base 208 so as to be slidable in the X-axis direction. The guide 254 holds the stopper 252 in a state where the movement of the Y axis and the Z axis of the stopper 252 is restricted.

  As shown in FIG. 11B, a rotating body 256 that rotates together with the pinion 226 is fixed to the upper surface of the pinion 226. Above the pinion 226, a substantially disc-shaped sliding body 258 that can slide in the Z-axis direction with respect to the rotating body 256 is provided. The rotating body 256 is provided with a hollow portion 286, the sliding body 258 is provided with a hollow portion 288, and a spring 260 is disposed in the hollow portion 286 and the hollow portion 288. The sliding body 258 is loaded with an upward biasing force by a spring 260. The rotary body 256 is provided with a key 262, and the slide body 258 is provided with a key groove 264 with which the key 262 is engaged. The slide body 258 can rotate around the rotation center axis C1 together with the rotary body 256. It is. Since the rotating body 256 is fixed to the pinion 226, the pinion 226, the rotating body 256, and the sliding body 258 rotate around the rotation center axis C1. A knob 284 is provided on the upper surface of the sliding body 258 so that a hand can be easily caught and rotated when the sliding body 258 is gripped and rotated. A ball bearing 266 is provided around the sliding body 258. An inner race 268 of the ball bearing 266 is fixed to the outer periphery of the sliding body 258. The outer race 270 of the ball bearing 266 is pin-coupled near one end 274 of the two links 272. The vicinity of the other end 276 of the two links 272 is pin-coupled to the two stoppers 252 respectively.

  As shown in FIG. 10 (c), the adjusting means 218 lowers the sliding body 258 so that the right link 272 moves around the one end 274 as shown in FIGS. 11 (b) and 12 (b). The right stopper 252 that rotates counterclockwise and is connected to the right link 272 is configured to move in the positive X-axis direction. Further, by lowering the sliding body 258, as shown in FIGS. 11B and 12B, the left link 272 rotates clockwise around one end 274 and is connected to the left link 272. The left stopper 252 is configured to move in the negative X-axis direction. That is, the adjusting means 218 lowers the sliding body 258 so that the two stoppers 252 move away from each other and disengage from the tooth portion 250 of the pinion 226 so that the pinion 226 can rotate. It is configured as follows.

  Further, as shown in FIG. 10C, the adjusting means 218 includes a pin 280 that bites into the tooth portion 250 of the pinion 226 by a biasing force in a direction toward the rotation center axis C <b> 1 of the pinion 226 by the spring 278. When the pin 226 rotates the pinion 226, the pin 280 detaches from one tooth of the tooth portion 250 against the urging force of the spring 278 and then sequentially bites into other adjacent teeth. Thereby, a person who rotates the sliding body 258 to rotate the pinion 226 can feel a sense of moderation (intermittent resistance) and can grasp the rotation angle of the pinion 226 to some extent. Further, since the present invention has a structure in which the stopper 252 is inserted into the tooth portion 250 of the pinion 226 for positioning, the smallest unit for changing the position of the rack 224 is one gear tooth. By recognizing the movement of the rack 224 for each tooth by hand, the user can optimally operate the position of the rack 224.

  The operation and effect of the massage device 200 having the above configuration will be described below. Unless otherwise indicated, description will be made in chronological order. The massage device 200 is used by placing it on a floor or the like with the lower surface 206 facing down. By placing the body torso etc. on the first spherical body 202 and the second spherical body 204, the reaction force against the weight of the body is loaded from the first spherical body 202 and the second spherical body 204 to the trunk, etc. The torso is massaged. Thereby, a torso etc. can be massaged, without requiring arm strength.

  When it is desired to shorten the distance between the first spherical body 202 and the second spherical body 204 for reasons such as changing the body part to be massaged, the sliding body 258 is manually lowered as shown in FIG. Press down to lower. The right link 272 rotates counterclockwise around one end 274, the left link 272 rotates clockwise around one end 274, and the two stoppers 252 are disengaged from the teeth 250 of the pinion 226. The pinion 226 and the sliding body 258 fixed to the pinion 226 can be rotated. Therefore, in a state where the body is slightly lifted from the second spherical body 204, the sliding body 258 is rotated counterclockwise in plan view, and the pinion 226 is rotated counterclockwise in plan view. The rack 224 that meshes with the pinion 226 moves in the negative direction of the X axis. As a result, the housing 216 connected to the rack 224 slides in the negative X-axis direction, and the second spherical body 204 placed on the housing 216 moves in the negative X-axis direction. The distance between the body 202 and the second spherical body 204 can be shortened. At this time, the two ball bearings 234 come into contact with the inner surface 242 or 243 of the rack 224.

  When the distance between the first spherical body 202 and the second spherical body 204 is shortened to a desired distance, the sliding body 258 is released. As shown in FIG. 11 (b), the sliding body 258 is raised by the biasing force of the spring 260. The right link 272 rotates clockwise around one end 274, the left link 272 rotates counterclockwise around one end 274, and the two stoppers 252 bite into the teeth 250 of the pinion 226. The sliding body 258 and the pinion 226 are restricted so as not to rotate.

  When it is desired to increase the distance between the first spherical body 202 and the second spherical body 204 again, as in the case where the distance between the first spherical body 202 and the second spherical body 204 is shortened, as shown in FIG. As shown, the sliding body 258 is pushed down by hand and lowered to make the pinion 226 and the sliding body 258 rotatable. Therefore, with the body slightly lifted from the second spherical body 204, the sliding body 258 is rotated clockwise in FIG. 12A, and the pinion 226 is rotated clockwise in plan view. A rack 224 that meshes with the pinion 226 moves in the X-axis positive direction. As a result, the housing 216 connected to the rack 224 slides in the X-axis positive direction, and the second spherical body 204 placed on the housing 216 moves in the X-axis positive direction. The distance between the body 202 and the second spherical body 204 can be increased again.

  When the distance between the first spherical body 202 and the second spherical body 204 is increased to a desired distance, the hand is moved from the sliding body 258 similarly to the case where the distance between the first spherical body 202 and the second spherical body 204 is shortened. The sliding body 258 and the pinion 226 are restricted so as not to rotate.

  According to the massage device 200, the distance between the first spherical body 202 and the second spherical body 204 can be changed by rotating the pinion 226 of the rack and pinion mechanism 228 and moving the rack 224. For this reason, according to the site | part which a body massages, the distance of two acupressure points can be changed easily. When finger pressure is applied, the stopper (locking means) 252 can restrict the pinion 226 so that it cannot rotate, and the rack 224 can be restricted so that it cannot move in the X-axis direction. For this reason, the rack 224 does not move in the positive direction of the X-axis due to the weight applied obliquely downward to the second spherical body 204 from the body, and the distance between the first spherical body 202 and the second spherical body 204 is increased. Can be maintained.

  As mentioned above, although embodiment of this invention was described based on drawing, this invention is not limited to illustrated embodiment. For example, the massage device of the present invention is not limited to use for waist massage, and may be used for massage of the head, neck, back, buttocks, legs, and the like.

  Further, all of the massage device of the present invention may be used in a bag. For example, the entire massage device 10 shown in FIG. 1 may be used in a bag.

  Further, a part or the whole of the first spherical body and the second spherical body may be formed from a permanent magnet so that not only a massage effect by pressing but also a massage effect by magnetic force is generated. Further, a part or the whole of the first spherical body and the second spherical body may be formed from a permanent magnet, and the base may be composed of a metal such as iron that can be adsorbed by the first spherical body and the second spherical body. By adsorbing the first spherical body and the second spherical body to the base, it is possible to prevent the first spherical body and the second spherical body from being detached from the base.

  Moreover, in the massage apparatus 10 shown in FIG. 1, you may remove and use both the 3rd spherical body 30 and the 4th spherical body 32, or one side. By removing both or one of the third spherical body 30 and the fourth spherical body 32, the distance between the first spherical body 12 and the second spherical body 14 can be adjusted according to the physique and the like.

  Moreover, a guide part is not limited to a slot or a slot, Two rails which can mount a 1st spherical body and a 2nd spherical body may be sufficient.

  Moreover, the elastic force of a 1st spherical body and a 2nd spherical body may be changeable. The elastic force can be changed by replacing the first spherical body and the second spherical body, or by providing elastic force changing means in the first spherical body and the second spherical body. For example, when a strong finger pressure is applied, the first spherical body and the second spherical body have an elastic force similar to that of a hard ball. When a weak finger pressure is applied, the first spherical body and the second spherical body have an elastic force similar to a hard tennis ball. Let it be the body. By changing the elastic force, the areas of the first spherical body and the second spherical body that follow the acupressure part change, the surface pressure distribution changes, and the intensity of the acupressure changes. Thereby, finger pressure can be changed.
