Description

  The present invention relates to a body massager, and in particular, the distance between the skin surface and bone is small (hereinafter referred to as thin skin), such as around the head and knees, and the elasticity is poor, making it difficult to massage with a device. The present invention relates to a massage device capable of effectively performing massage around the scalp and knee.

  Various proposals have been made as a body massager, but in recent years, massage has been encouraged to prevent hair loss and prevent hair growth, and as a means to improve its effectiveness, A massager has been proposed.

  However, the conventionally proposed massager is large and expensive, so it is difficult to use at home easily. Unlike other parts, the scalp and knee are thin and the skin is not very elastic. There is a drawback in that the massaging member does not contact the affected area uniformly and feels pain, hurts the skin, and hurts the hair, so that a sufficient massage effect cannot be obtained.

Conventionally proposed massagers include the following.
Japanese Patent Application Laid-Open No. 10-216185 is dedicated to scalp massage, but has the following problems. (1) Since the apparatus is large and expensive, it is difficult to easily install it in a home. (2) Since the apparatus uses an elastic body and an eccentric shaft to deform the elastic body to cause circular motion, the power loss is large and uneconomical. (3) Since the stagnation member is supported by an elastic body and its deformation is used, there is a problem in durability. (4) Since the kneading member covers a wide area of the head, it is difficult to massage the scalp uniformly according to the size and shape of the head, which varies from person to person.

Japanese Patent Application Laid-Open No. 5-42192 prevents clothes from being caught in the squeezing member, but the connector is rotatable on the inclined shaft to which the squeezing member is attached. Conical movement with. Therefore, since the itch member does a pestle motion and the itch member does not hit the affected area evenly, the massage of the scalp and knees with thin skin and low elasticity may cause pain or damage the skin. was there.

Japanese Patent Laid-Open No. 2003-111811 is dedicated to scalp massage, and only the surface of the scalp is stimulated by vibrating the brush or protrusion in the vertical direction of the scalp by vibration generating means, and the effect of massage was small .

  An object of the present invention is to provide a safe, small, and inexpensive massager with a large blood circulation promoting effect that does not damage the scalp, knees, and the like in view of the above-described conventional drawbacks.

The present invention has the following configuration as a first means for solving the above problems.
A driving means, a rotating disk rotatably supported on a machine frame of the driving means and coaxially connected to a driving shaft of the driving means; and a position eccentric to the rotation center of the rotating disk on the rotating disk. A main shaft rotatably arranged; and a rubbing member supported non-rotatably at one end of the main shaft, and the machine frame of the driving means and the main shaft are engaged by a rotation conducting means, The rotation direction and the rotation direction of the main shaft are opposite to each other, and the kneading member is configured to perform only a circular motion on a single plane without rotating with respect to the machine frame of the driving means.

A second solution is to set the diameter of the kneading member to make a circular motion in a range of 10 to 16 mm, so that the scalp feels painful, and the redness of the scalp can be appropriately massaged.
In determining the optimum diameter, several people were evaluated for the comfort that a person feels when massaged and the change in redness of the scalp. When the diameter was out of the range and the diameter was as small as 5 to 8 mm, the massage was unsatisfactory and the change in redness of the scalp was small. When the diameter exceeded 20 mm, there was a feeling of pain and the change in redness of the scalp was greatly anxious. When the diameter was 18 mm, a little anxiety was felt as described above.
The diameter of the circular motion of 10 to 16 mm was almost close to the lateral movement distance of 12 to 16 mm of the evaluator's scalp. The lateral movement distance is the distance that the scalp can easily move relative to the skull without feeling pain, and was measured by the method shown in FIG.

  In addition, there is a support member that supports the scuffing device M (see FIG. 1) with respect to the scalp, and a pressing means (spring element) that engages against the scuffing device M against the support member is disposed. When the kneading member of the kneading device M is pressed against the scalp, the support member comes into contact with the scalp against the pressing means (spring element). If the lateral movement distance of the scalp is smaller than the diameter of the circular motion of the kneading member, the pressing means (spring element) is displaced so that the kneading device M is swung.

As is clear from the above description, the present invention has the following effects.
(1) A spindle that supports the squeezing member is rotatably disposed at a position that is eccentric with respect to the rotation center of the rotating disk that is rotationally driven by the driving device, and the rotating direction of the rotating disk and the rotating direction of the main axis are mutually different. In the reverse direction, the main shaft does not rotate with respect to the driving device. Therefore, the squeezing member supported non-rotatably on the main shaft does not rotate and can only perform a circular motion on almost one plane, so that the affected part can be pressed uniformly, and the skin like the head and knees can be pressed. However, it is possible to perform massage safely without feeling pain and damaging the skin even in the massage of the affected part which is thin and small in elasticity.

  (2) In addition, it can be configured with gears or sprinkling conduction as the rotational conduction means, and does not require the force to deform the elastic body as in the prior art, so it provides an energy-saving and durable massager with low power loss can do. Furthermore, the device is small, portable and inexpensive.

  (3) Since the diameter of the circular motion of the itching member is set to the value of the scalp with a relatively small lateral movement distance, excessive friction between the itching member and the skin can be prevented even in massage of other parts. A comfortable massage is possible without hurting, and circulation of blood circulation is promoted.

(4) When the pressing means (spring element) is movable in the axial direction with a predetermined force until the end surface of the support member comes into contact with the scalp, and the lateral movement distance is less than the diameter of the circular motion of the kneading member The squeezing device is swingable by the displacement of the pressing means (spring element). Accordingly, since it is possible to cope with individual differences such as the size, shape, and lateral movement distance of the head, it becomes possible to bring the squeezing member into contact with the skin with an appropriate pressing force, and the effect of the item (3) can be further improved. You can get a comfortable feel to massage with your palm.

  Hereinafter, the Example at the time of using embodiment of this invention as a massage device of a scalp is described based on figures.

1 is a cross-sectional view of an embodiment of the present invention, FIG. 2 is an explanatory view showing the engagement and rotation direction of a gear in the XX cross-sectional view of FIG. 1, and FIG. 3 is a massage by applying the apparatus of FIG. FIG. 4 is a plan view of the kneading member in FIG.
A machine frame of the driving device A composed of the motor 1 and the speed reducer 2 is integrally fixed to the frame 4 with bolts 2c. A turntable 5 is rotatably disposed on the frame 4 via a bearing 3. A drive shaft 2 a that protrudes from the speed reducer 2 and has a serration 2 b at the tip passes through a hole 4 a coaxial with the center of the frame 4, that is, the rotating disk 5, and engages with a serration 5 a formed at the center of the rotating disk 5. Yes.

A fixed gear 4b is integrally formed coaxially with the hole 4a of the frame 4. In addition, the rotating disk 5 has a through hole 5b at a predetermined distance from the center (in this embodiment, the radius is 8 mm, but this distance is the radius of the circular motion of the stagnation member). A main shaft 6 is rotatably arranged, and a main gear 7 is fixed to one end of the main shaft 6. The gear ratio between the fixed gear 4b and the main gear 7 is 1: 1. An intermediate gear 8 that engages with each of the fixed gear 4 b and the main gear 7 is rotatably disposed on an intermediate shaft 9 that is supported by the rotating disk 5.
The cover 21 is formed of a cloth in a cylindrical shape, and both ends thereof are fixed to the outer periphery of the frame 4 and the face plate 11 so that clothes, hair, and the like are not wrapped around the rotating part during massage.

A joint 12 is attached to the other end of the main shaft 6 via a pin 13 so as to be swingable by a predetermined angle in the left-right direction in FIG. A face plate 11 to which the kneading member 10 is attached is attached to the joint 12 via a pin 14 and can swing at a predetermined angle in a direction perpendicular to the swinging direction by the pin 13. A rubbing member 10 is fixed to the face plate 11 with a bolt 15 via a washer 16. The retaining ring 6b and the washer 6a mounted in the groove of the main shaft 6 receive the thrust force from the squeezing member 10.
The kneading member 10 is formed with a plurality of protrusions 10a having hemispherical tips, and engages with the scalp during massage. One protrusion 10 b is formed on the opposite side of the protrusion 10 a of the rubbing member 10 and engages with the hole 11 a of the face plate 11 to prevent the rubbing member 10 from rotating with respect to the face plate 11.
The object of the present invention can be achieved with only the apparatus configured as described above. (Hereinafter, the above configuration is referred to as a massaging device M.)

A plurality of pins 17 (three in this embodiment) are fastened to the frame 4 of the kneading device M with nuts 17a, and the pins 17 and the holes 19c of the cylindrical support member 19 are engaged. . A compression coil spring 18 is mounted between the support member 19 and the flange 17b of the pin 17, and the squeezing device M is configured to be movable with a predetermined force against the compression coil spring 18.
The cover 20 covers the driving device A of the kneading device M and is fixed to the support member 19 with bolts 19a.

Next, the operation of the massager of the present invention will be described.
When a power disk (not shown) is turned on to the motor 1 and the rotating disk 5 engaged with the drive shaft 2a of the speed reducer 2 rotates in the direction of arrow B in FIG. The shaft of the supported main gear 7 and the intermediate gear 7 moves in the direction of arrow B, and the intermediate gear 8 that meshes with the fixed gear 4b rotates around the fixed gear 4b while rotating in the D direction. The main gear 7 meshing with the intermediate gear 8 rotates in the C direction. That is, when the rotating disk 5 rotates once in the B direction, the main shaft 6 rotates once in the C direction opposite to the rotating disk 5, and the main shaft 6 does not rotate with respect to the driving device A. By the above operation, the rubbing member 10 that is non-rotatably supported by the main shaft 6 does not rotate but only performs a circular motion on substantially one plane.

Next, when holding the cover 20 or the support member 19 by hand (not shown) and the kneading member 10 is pressed against the scalp as shown in FIG. 3, the compression coil spring 18 is compressed until the tip 19b of the support member 19 hits the scalp. Then, the protrusion 10a is pressed against the scalp, and massage is performed by the pressing force of the compression coil spring.
At this time, when the rubbing member 10 hits the scalp, the rubbing member 10 swings at the joint 12 and the face plate 11 and hits uniformly along the shape of the head. The appropriate pressing force is preferably set to 500 to 1500 g although there are individual differences. In this embodiment, it is about 800 g.

  In this embodiment, an intermediate gear is interposed between the fixed gear and the main gear as the rotation conducting means, but winding conduction such as a pulley and a timing belt may be used instead of the gear. In this case, the intermediate gear used in this embodiment is not necessary.

  In this embodiment, the diameter of the kneading member 10 is 80 mm, but a range of 50 to 120 mm is preferable. If the diameter of the kneading member 10 increases so as to cover the entire head, the movement of the kneading member 10 is restricted and the effect of massage is reduced, which is not preferable.

In this embodiment, rubber having flexibility is used as the material of the squeezing member 10, but it may be formed of plastic or the like.
As shown in FIG. 4, a plurality of protrusions 10a of the rubbing member 10 are arranged circumferentially at a predetermined interval, and the tips thereof have a concave shape curved in a semispherical shape. It is slightly larger than the size of the head.
The protrusion 10a preferably has a taper shape with a base larger than the tip, and the tip has a hemispherical shape with a radius of 1 mm to 2 mm. In this embodiment, the height is 6 mm and the tip is a hemisphere with a radius of 1.5 mm. The shape of the protrusion 10a can be exchanged with one having a different diameter or length depending on the portion of the protrusion 10a. If the radius of the hemisphere is matched to the head, it can be used for massage of the knee and other parts.

  Although the number of circular motions of the kneading member 10 is 100 times / minute in this embodiment, the number of times it feels comfortable is different among individuals, so it may be freely variable at about 60 to 150 times / minute. .

Hereinafter, the form of a present Example is demonstrated based on FIG. Note that only parts different from those in the first embodiment are denoted by reference numerals.
In the form of the first embodiment, the face plate 11 fixed to the stagnation member 10 is swung with respect to the main shaft 6 when the squeezing member 10 is pressed against the head. The two chamfers 101 a formed on the face plate 102 and the two chamfers 102 a formed on the face plate 102 are engaged with each other and fastened with a nut 104. The rubbing member 103 is fixed to the face plate 102 by a bolt 101 b and a nut 106 at the tip of the main shaft 101.

In this embodiment, when the protrusion 103a of the kneading member 103 of the kneading device M is pressed against the head, the compression coil spring 107 is compressed and the tip 108a of the support member 108 contacts the head. If the kneading member 103 is tilted along the shape of the head, the compression coil spring 107 is displaced and the axis of the kneading device M is tilted. (Not shown)
Since the axis of the massaging device M is inclined, it is possible to deal with individual differences such as the size of the head, the shape, and the lateral movement distance of the skin, so that the massaging member can be brought into contact with the skin with an appropriate pressing force. .

This embodiment is configured exclusively for scalp massage, and is capable of simultaneously massaging a wide range of the head in order to shorten the massage time.
Hereinafter, the form of a present Example is demonstrated based on FIG. 6, FIG.
The massager 204 is one in which three massagers of the first embodiment are arranged on the frame 201. The massager is swingably disposed by a bracket 201a that penetrates a hole 201b provided in the frame 201 and is integrally fixed to the machine frame, and a pin 202 that protrudes from the massager 204.
When massaging, the hand is put in the holes 201c formed on both sides of the frame 201 and the handle 203 (not shown) is pressed against the head of the massaging device. Corresponding to the shape, it swings at the portion of the pin 202 so that it contacts the scalp evenly. In this embodiment, three massagers 204 are provided , but the number may be two or more than three.
In this embodiment, the position of the three massagers 204 with respect to the head is fixed, but the frame with the three massagers is rotated and moved slowly with respect to the head using the rotation means. As a special configuration, the entire scalp can be massaged .
