[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a massager for improving blood circulation by stimulating the fingertip side of a hand or a foot, and particularly, an inter-finger massager which can be continuously used for a long period of time. Regarding

[0002]

2. Description of the Related Art In general, various massagers have been proposed for stimulating fingers and toes to improve blood circulation. For example, a massager has been proposed in which convex portions are provided at predetermined intervals on the surface of a cylindrical or spherical main body, and a band for wearing is provided at a predetermined position of the main body member. In this massager, the band is turned around and attached to the back of the hand, and the main body is grasped by the palm, so that the convex portion provided on the surface of the main body stimulates the fingers and the palm.

Further, as a device for fingers for improving gripping force, one having a convex portion provided at a predetermined interval on the surface of a main body formed of an elastic body such as rubber and formed in an annular body or a spherical body. Is proposed. This device moves the muscles of the fingers by grabbing and deforming the body of the device with the palm, and promotes the improvement of grip strength.At the same time, when the device is squeezed, the projections formed on the surface of the device Since the part stimulates the fingers and palm, the muscle strength of the fingers is improved and blood circulation is improved.

Further, as a massager for massaging the toes and the sole of the foot, there has been proposed a structure in which a plurality of convex portions are provided on the surface of a curved main body portion at predetermined intervals. This massager. The curved surface is stepped on the sole of the foot to stimulate the sole of the foot.

[0005]

However, the massage device having the above structure has the following problems. Massager used for fingers or soles,
It is configured to squeeze or tread on the palm to stimulate the fingers or soles of the feet, but especially positively consciously applying force to move the fingers or step on the feet,
It is necessary to operate the massager, which causes some fatigue. Therefore, it is difficult for the user to get tired of it like a general exercise equipment and to continuously use it.

When a massage device is used, the fingers and the like are stimulated by performing a gripping action with the palm, but at this time, the palm easily sweats, and since the breathability is not taken into consideration in the massage device, the massage with the sweat is performed. The vessel was dirty and slippery, making it difficult to use.

[0007] Since the massager for the sole of the foot is configured to accelerate blood circulation by stepping on it with the foot and stimulating the sole of the foot, the massager can be used unless it goes to the position where the massager is placed. In addition, it is necessary for the user to always be aware of the use and to use it while standing up, and it was not possible to use it in a relaxed position such as a lying position.

The present invention was devised to solve the above-mentioned problems, and can be used with almost no awareness of the massager, has excellent breathability, and stimulates the toes of the user's posture. Can be used without being trapped in
An object of the present invention is to provide an inter-finger massager which can be comfortably used during use even if the massager is used with fingers or toes.

[0009]

In order to solve the above-mentioned problems, the present invention comprises a tubular body to be inserted between a hand or a toe and a connecting portion for fixedly supporting one end of the tubular body. The tubular body has a core and a flexible outer cylinder that covers the outer circumference of the core, and the outer cylinder serves as an inter-finger massager having a protrusion on the outer circumference thereof. Configured.

Therefore, by inserting the tubular body between the four fingers other than the thumb and holding the hand, or pressing the side portion of the forefinger with the thumb, the tubular body is contacted. The side surface between the four fingers in contact presses the tubular body. At this time,
The four-finger side portion compresses and deforms the tubular body, but receives the reaction force generated by the resistance of the rigid core portion. Therefore, the protrusion provided on the surface of the cylindrical body receives a stimulus corresponding to the pressing force of the four fingers.

Further, the outer cylinder portion may be formed with a ventilation hole penetrating the outer cylinder portion at a predetermined position between the protrusions.

Therefore, even if the massager is used by inserting it between the fingers or between the toes, the air can flow through the ventilation holes formed between the protrusions and the air permeability is excellent.

Further, it is composed of a tubular body to be inserted between fingers of the fingers other than the thumb, and a connecting portion for fixedly supporting one end of the tubular body. The tubular body comprises a core portion and a core portion thereof. An outer cylinder part having flexibility to cover the outer circumference, the outer cylinder part is provided with a protrusion on the outer circumference side thereof, and the connecting part is provided with a gripping part below the connection part, which is gripped by a palm by an attaching means, The grip is
It is composed of a core portion provided inside and an outer sphere portion having flexibility to cover the core portion. The outer sphere portion has protrusions on its surface portion, and the outer sphere portion is provided at a predetermined position between the protrusions. It was configured as an inter-finger massager having ventilation holes penetrating the ball.

Therefore, it is possible to apply stimulation to the palm as well as stimulation between the four fingers. When fingers and palms are stimulated, the cylindrical body and the outer sphere of the gripping part are elastically deformed by the fingers or palm, but the reaction force generated by the resistance of the hard core part causes the surface of the cylindrical body to react. The protrusions provided provide a stimulus corresponding to the pressing force of the four fingers and the palm. Further, since the tubular body and the grip portion are provided with the ventilation holes, the air permeability is good and it is possible to suppress the perspiration.

Then, a tubular body inserted between the toes, a support portion for fixedly supporting the tubular body, and the tubular body provided laterally at a position abutting the heel portion of the foot on the rear side of the support portion. A shape,
The supporting member comprises a convex portion installed at a position where it abuts against the arch portion of the foot, and the tubular body has a core portion and an outer cylindrical portion having flexibility to cover the outer periphery of the core portion. The outer cylinder portion is formed as a finger mass massager in which protrusions are provided on the outer peripheral side of the outer cylinder portion, and ventilation holes penetrating the outer cylinder portion are formed at predetermined positions between the protrusions.

For this reason, when the inter-finger massaging device is attached to the foot, the tubular body is compressed by the toes of the foot each time when the user walks, but the reaction force is received by the resistance of the core. , Stimulate the space between the toes by the protrusion. In addition, the convex portion abuts and presses against the arch to give a stimulus. Further, since the tubular body is laterally provided in the heel portion, the outer tubular portion is compressed, but since the reaction force is received by the resistance of the core portion, it is possible to stimulate the heel portion by the protrusion. Become.

FIG. 4 is a perspective view of a massager showing an application example of another embodiment, FIG. 5 is a principle diagram showing an application example, and FIG. 6 is a perspective view showing an application example of a massager for toes. Is.

As shown in FIG. 1, a finger massager 1
Comprises a tubular body 2 inserted between four fingers excluding the thumb, and a connecting portion 8 for fixing and supporting the tubular body 2 at a lower end of the tubular bodies 2 with a predetermined gap therebetween. The tubular body 2 is configured such that the outer tubular portion 3 formed of a member such as a flexible plastic that can be elastically deformed by the force of a finger and the inner tubular portion 3 is fixed to the connecting portion. The outer cylinder portion 3 and the core portion 5 made of a material such as plastic having rigidity. Further, the outer cylindrical portion 3 is formed with projections 4 in the axial direction at predetermined intervals along the circumferential direction.

The core portion 5 arranged in the outer cylinder portion 3 may be formed of a rod-shaped member such as wood or metal, and is more rigid than the flexibility of the outer cylinder portion 3. I am trying. The connecting portion 8 is formed of a thin sheet-shaped member, and is preferably formed of an elastic member such as plastic or rubber, and the lower end portion of the tubular body 2 is Adhesive bonding,
Alternatively, it is fixedly supported by connecting means such as welding by heat.

As the connecting means for fixing and supporting the tubular body 2 to the connecting portion 8, the outer tubular portion 3 and the core portion 5 are separated by a predetermined distance at a predetermined position of the outer tubular portion 3 and the core portion 5. The connection may be made in a state, and a fitting convex portion formed in a water drop shape may be formed at a position on the lower end side of the tubular body 2. Then, the connecting portion 8 is provided with a through hole at a predetermined position along the longitudinal direction of the connecting portion 8, and the fitting convex portion on the lower end side of the tubular body 2 is attached to and detached from the perforation of the connecting portion 8. The structure may be fixed and supported by freely fitting. At this time, the number of perforations formed in the connecting portion 8 is larger than the number of the tubular bodies 2, so that the tubular body 2 can be formed in accordance with the size of the hand of the user.
It is convenient because the installation interval can be changed.

Therefore, as shown in the phantom line in FIG. 1, the inter-finger massager 1 is used as follows when it is worn on the fingers. That is, with the connecting portion 8 of the inter-finger massager 1 on the palm side, the inter-finger massager 1 is attached to the hand by inserting the tubular body 2 between the four fingers excluding the thumb. Then, when the side surfaces of the fingers are moved toward each other, the side surfaces of the fingers compress and deform the outer tube portion 3, but the elastic force of the outer tube portion 3 restores the outer tube portion 3 contact portion of the finger. Is stimulated. It should be noted that the portion of the finger that abuts the protrusion 4 provided on the outer tubular portion 3 receives a stronger stimulus than the position without the protrusion 4.

When a force is applied by the thumb in the direction of pressing the side portion of the index finger, the stronger stimulus can be received. That is, although the side surfaces of the four fingers largely elastically deform the outer tubular portion 3, they are subjected to a reaction force generated by the resistance of the core portion 5 in the outer tubular portion 3. Therefore, the protrusion 4 of the outer tube portion 3 causes
It is possible to give a strong stimulus to the contact part of the finger.

Further, when a stronger stimulus is desired, it is possible to apply a stimulus between the fingers by grasping the fingers while the inter-finger massager 1 is attached and by grasping the fingers. In this case, it is possible to freely adjust the stimulus applied between the fingers by adjusting the grasping force.

When the inter-finger massaging device 1 is mounted, the coupling part 8 is only on the proximal side of the phalangeal bone on the palm side, and the member of the inter-finger massaging device 1 is located at a position to be covered by the palm. Therefore, when the fingers that are clenched are opened, the outside air hits the palm side, the air permeability is good, and the harmful effects of sweating can be prevented. Moreover, in order to further improve the air permeability between the fingers, as shown in FIG.
By adopting the configuration shown in, the breathability can be improved.

That is, as shown in FIG. 2, the outer cylinder portion 3A
Is configured by arranging the strip-shaped annular bodies 3a in a vertically separated manner. Then, on the outer peripheral side of the ring body 3a, projections 4a are provided in the axial direction at predetermined intervals in the circumferential direction. Therefore, the ventilation hole 6 is formed in the portion surrounded by the protrusion 4a and the ring body 3a.

Therefore, when the outer cylinder portion 2A having this structure is used in the inter-finger massaging device 1 shown in FIG. 1, the breathability of the inter-finger massaging device 1 mounted between the fingers is improved and sweating is prevented. You can Note that the core portion 5 and the connecting portion 8 in FIG. 2 have the same configuration as that in FIG. 1 described above. Further, the ring body 3a and the protrusion 4a in FIG. 2 may be integrally formed. Furthermore, the protrusions 4 and 4a shown in FIG.
The configuration shown in FIG. 3 may be used.

That is, as shown in FIG. 3A, the protrusion 4b of the outer cylindrical portion 3B may be installed in a direction orthogonal to the axial direction. Further, as shown in FIG. 3 (b), it may be a protrusion 4 c having a larger inclination angle with respect to the axis of the outer cylindrical portion 3 C, or as shown in FIG. 3 (c), the outer cylindrical portion 3 D.
The protrusion 4d may be provided with an inclination angle smaller than the axis line of.

Further, as shown in FIG. 3 (d), the outer cylindrical portion 3
A configuration in which a granular protrusion 4e is provided on E may be used. Further, as shown in FIG. 3 (e), the outer cylinder portion 3F is provided with orthogonal projections 4f, or, as shown in FIG. 3 (f), the outer cylinder portion 3G is orthogonal to the outer cylinder portion 3G at a predetermined angle. There may be a configuration in which 4 g is provided. It should be noted that the cylindrical portions 3B and 3 in FIG.

When the finger-to-finger massager 1 is attached to the toes, the finger-to-finger massager 1 is supported by being sandwiched between fingers regardless of whether the user's posture is lying down, sitting or walking. Therefore, the mounted state can be maintained without coming off.

If there is a risk that the inter-finger massager 1 will come off, wearing socks will prevent the inter-finger massager 1 from coming off. When used between the toes, the fingers are forcibly separated from each other by the tubular body 2, which is excellent in breathability like the tubular body 2A having the configuration shown in FIG. By using it, as a result of improving the air permeability between fingers, it is possible to prevent skin diseases such as Trichophyton caused by humidity. In addition, when the inter-finger massager 1 is attached to the toes, the distance between the fingers is narrower than when it is used to the fingers, but the connecting portion 8 can be freely elastically deformed, so that there is no hindrance to the attachment. .

When the inter-finger massage 1 is attached to the toes, the toes cannot be moved in the same manner as the fingers of the hand, but by moving the toes in the direction of bending to the sole side of the toes, as shown in FIG. Explaining with reference to FIG. 5, the outer cylinder portion 3A is elastically deformed and compressed, but receives a reaction force generated by the resistance of the rigid core portion 5, so that the protrusion 4a of the outer cylinder portion 3A stimulates between the legs. Can be received.
