Description

The present invention relates to a massage machine that massages an affected area (neck, shoulder, waist, thigh, etc.) of a user. In particular, the present invention has a U-shaped appearance, and even when users with different physiques use it for massage, or when the same user massages different affected areas, the massage part can be used. The present invention relates to a handy type massage machine capable of reliably contacting an affected area (treated area).

Conventionally, a handy type massage machine that massages the neck and shoulders (sometimes referred to as the neck and shoulders together) has been known.
For example, Patent Document 1 discloses a massage machine having a U-shaped external shape that can be wrapped around the neck of a user. The massage machine of Patent Document 1 is formed in a substantially U-shape as a whole, and a massage portion having a massage function is provided inside. The massage portion is composed of a central massage portion that abuts around the rear of the neck, both side massage portions that abut on both shoulders, and both tip portions that are curved so as to follow the front sides of both shoulders. .. In this massage machine, the massage portion is bent in a U shape that opens toward the front, and the massage portion is attached so as to be located at the neck / shoulder portion, so that the circumference of the neck / shoulder portion can be massaged.

In this massage machine, the width of the openings at both tips of the massage section is formed to be narrower than the width of the neck, and when in use, hold both tips of the massage section to widen the openings from behind the neck. A massage machine is hung around the neck so that the opening side is located on the front side of the shoulder. In this way, since both tip portions are curved so as to follow the front side of the shoulder portion, it is possible to maintain a state in which the massage portion is fitted to the affected portion (neck / shoulder portion) of the user. Then, the central massage portion abuts on the acupuncture points around the back of the neck, and the massage portions on both sides also abut on the acupuncture points on both shoulders, so that effective massage can be realized.

Japanese Unexamined Patent Publication No. 2002-685

The above-mentioned Patent Document 1 discloses that the width of the opening of the massage machine is formed to be narrower than the width of the neck, and that the opening is widened and hung around the neck. However, if the physique of the user is different, the width of the neck is different, and depending on the user, it may not be possible to maintain the state in which the massage part is fitted to the affected part.
Further, in the massage machine of Patent Document 1, both side massage portions are formed of a soft material such as urethane foam so that the opening can be widened. Therefore, when the user grasps the massagers on both sides by hand and turns them backward in order to attach the massager of Patent Document 1 to the neck and shoulders, the massagers on both sides may bend and hang down. There was a drawback that it was difficult to handle. In order to eliminate this drawback, it is possible to increase the amount of soft material that constitutes both sides of the massage, but in that case, it becomes difficult to widen the opening of the massager, or the massager itself becomes bulky. There is no denying the possibility that it will be high.

By the way, it is preferable not only to massage the neck and shoulders using the massage machine of Patent Document 1, but also to massage the waist and thighs. However, even for the same user, the width of the neck and the width of the waist and thighs are different, so if one massage machine is used together, it is difficult to keep the massage part fitted to the affected part. Is. Further, when the massage machine of Patent Document 1 is to be used on the waist of a user having a large physique, the massage parts on both sides of the massage machine cannot be greatly expanded, and there is a possibility that the massage machine cannot be worn. That is, in the case of the massage machine of Patent Document 1, it is difficult to effectively massage the neck / shoulder, lumbar, thigh and the like of users of various physiques with one massage machine.

In addition, when trying to massage the user's back (for example, the back corresponding to the back side of the stomach), it is necessary to widen the opening and hang it around the neck, but the massage machine of Patent Document 1 is like this. It is not designed to withstand various usage modes.
The present invention has been made in view of the above circumstances, and is a massage machine having a U-shape, and the massage portion is surely in contact with the affected portion (treated portion) even if there is a difference in physique. It is an object of the present invention to provide a massage machine capable of effectively massaging not only the neck and shoulders but also other parts (lumbar, back, thigh, etc.).

In order to achieve the above object, the following technical measures have been taken in the present invention.
The massage machine of the present invention has a U-shaped shape including a main body portion provided with a massage mechanism for massaging the affected portion of the user and a pair of extending portions extending in a leg shape from both ends of the main body portion. The massage machine is characterized in that the pair of extending portions are rotatably connected to the main body portion in a horizontal plane.

Preferably, both ends of the main body portion in the left-right direction are bent portions extending upward, and the top portion of the bent portion and the base end side of the extending portion are connected by a connecting portion. It is preferable that the base end of the extension portion is rotatable about the center of the vertical axis by the connecting portion.
Preferably, the connecting portion has a hinge structure.
Preferably, the massage mechanism is stored inside the main body.

Preferably, the massage mechanism includes a drive motor, a swing arm portion that converts and transmits a rotational force generated by the drive motor into a push-pull operation, and the swing arm portion rotates with the rotational force of the drive motor. It is preferable to provide a steady rest member for preventing the above-mentioned movement, and a massage portion provided at the tip end portion of the swing arm portion and retracting from the main body portion.
Preferably, the massage mechanism has a pair of left and right massage portions, and the massage portions move back and forth alternately on the left and right.

Preferably, the stopper portion is formed on the base end side of the pair of extension portions so that the pair of extension portions does not spread beyond a predetermined angle.

According to the massage machine according to the present invention, even if there is a difference in the physique of the user, the massage part can surely contact the affected part and massage effectively, and not only the neck and shoulders but also the back and the like can be massaged effectively.

In particular, as shown in FIG. 1, the massage machine 1 has a U-shaped appearance as a whole. This massage machine 1 is a main body including a treatment part (massage part 3) that abuts on the affected part (neck and shoulder part in FIG. 1) of the user U and massages the affected part (the part to be treated, the part to be treated). A pair of left and right extension portions 4 extending from both ends of the main body portion 2 in a leg shape, an operation portion 5 including various switches provided on one extension portion 4, and a user U, respectively. It is composed of a grip portion 6 that is gripped by the hand.

Except for the massage portion 3, the main body portion 2 and the extension portion 4 are covered with a cushion material such as urethane, and further, the whole is covered with a cover such as artificial leather. The portion of the opening corresponding to the massage portion 3 is covered with, for example, an elastic mesh material.
As shown in FIG. 3, a massage mechanism is built in the main body 2 of the massage machine 1.

First, as shown in FIGS. 1 to 5, the main body 2 of the massager 1 has a wide bowl shape in the left-right direction, and a front housing 2a (FIGS. 3 to 3) in which an opening is formed toward the rear. 5) and a bowl-shaped rear housing 2b having an opening to be fitted into the front housing 2a. The front housing 2a and the rear housing 2b are formed of, for example, a synthetic resin having a certain degree of rigidity (referring to an engineering plastic having a certain degree of hardness, not something like rubber or an elastomer, the same applies hereinafter). There is. The main body 2 is formed by fitting the two housings 2a and 2b in the front-rear direction so that the opening of the front housing 2a and the opening of the rear housing 2b are aligned.

The main body 2 has a horizontally long width substantially corresponding to the shoulder width of a user U having a standard physique, and has a curved shape so that both left and right ends extend upward.
The front side of the main body 2, that is, the front housing 2a is provided with a pair of left and right openings 2c for the massage part 3 which will be described in detail to penetrate and project to the front side. The opening 2c is formed in the front housing 2a that rises toward the front side, and is opened in an elliptical shape (an elliptical shape that is long in the left-right direction) when viewed from the front.

As shown in FIGS. 1 to 3, a pair of left and right extension portions 4 extending forward from the left and right end portions of the main body portion 2 are provided on the left and right end portions of the main body portion 2. The extension portion 4 has a length that extends beyond the shoulder of the user U and reaches a position on the front side of the chest when the user U wears the massage machine 1 as shown in FIG. 8A.
The extension portion 4 is an elongated cylindrical body, and a cushioning material is wound around the cylindrical body. The base end side of the cylindrical body is connected to the left and right end portions of the main body portion 2 via a connecting portion 7 described later. As described above, although the main body 2 has a substantially rectangular shape extending horizontally in the left-right direction when viewed from the front, both the left and right sides extend upward so as to be caught upward, and an extension portion is extended to the top 2d of the raised portion. The bases of 4 are connected. The base portion of the extension portion 4 is bent downward in an elbow shape (an arc shape having a central angle of approximately 90 °), and the most base end portion of the base end portion 4a is fished via a connecting portion 7 described later. It is connected to the top 2d of the rising part.

Therefore, as shown in FIG. 1, the connecting portion 7 (the joint portion between the main body portion 2 and the extending portion 4) is located at a position above the horizontal position of the pair of left and right massage portions 3 in the front view. There is.
By the way, as shown in FIG. 1, the tip end portion of the extension portion 4 is a grip portion 6. An operation switch (operation unit 5) for operating the massage machine 1 is provided in the vicinity of the grip portion 6 of the extension portion 4 on the right side (a portion displaced toward the main body).

FIG. 6 shows an enlarged perspective view of the vicinity of the connecting portion 7 in the massage machine 1, and the connecting portion 7 will be described.
As shown in FIGS. 1 and 6, the main body 2 and the extension 4 are not fixedly connected, and the pair of extension 4s are opened with respect to the main body 2 by the connection 7 having a so-called hinge structure. It is connected so that it can be legged. That is, the state of FIG. 1 (the state of rotating 90 ° with respect to the folded state), the state of FIG. 2 (the state of rotating 140 ° with respect to the folded state), and the state of FIG. 7 (folded). The position of the extension portion 4 and the angle (rotation angle) in the horizontal plane can be changed to the state where the extension portion 4 is set (rotation angle 0 °).

As shown in FIG. 6, the connecting portion 7 has an elbow member 8 bent in an arc shape so that the tip end faces the lateral direction (forward) and the base end faces downward. The elbow member 8 has a 1/4 arc shape and is regarded as a solid member. The tip of the elbow member 8 is fitted with the base end portion of the extension portion 4, and both can be integrally fitted.
Further, the other end of the elbow member 8 is provided with a columnar extension pillar 8a extending further downward from the other end, and the tip (lower end) of the extension pillar 8a has a brim shape from the side wall of the extension pillar 8a. The disk-shaped engaging piece 8b that spreads out is formed so as to protrude.

Further, the top portion 2d of the raised portion of the front housing 2a described above is flat, and has a ring shape in which the central portion is hollowed out. The diameter (inner diameter) of the ring-shaped hollow portion is made to be playable in the extension pillar 8a and smaller than the diameter of the engaging piece 8b.
Specifically, the main body 2 is a combination of the front housing 2a and the rear housing 2b in the front-rear direction as described above, and the base ends of the elbow members 8 are attached to the left and right ends of the front housing 2a and the rear housing 2b. A recess 9 on the main body side is formed so that the extension pillar 8a on the side (lower end side) can penetrate. Each of the main body side recesses 9 is formed in a shape like a half of a cylinder, and when the front housing and the rear housing are combined, a substantially cylindrical housing portion can be formed at both left and right ends of the main body 2. It has become.

On the other hand, the extension portion 4 also has a shape in which the cylindrical body is halved like the main body portion 2, and the extension side recess 10 having a shape in which the cylinder is halved is provided on the base end side. It is formed. The extension-side recess 10 is formed in a semi-cylindrical shape that is bent in an arc shape corresponding to the upper end side of the elbow member 8 that is bent in an arc shape, and when the half-split members are combined, it becomes an arc shape. An elbow-side accommodating portion that can accommodate the tip end side (upper end side) of the curved elbow member 8 is formed.

That is, the tip end side (upper end side) of the elbow member 8 is accommodated in the elbow side accommodating portion of the extension portion 4, and the base end side (lower end side) of the elbow member 8 is accommodated in the main body side recess 9 of the main body portion 2. By combining the half-split members in this state, the extension portion 4 and the main body portion 2 are firmly connected with the elbow member 8 as the starting point.
Therefore, the front housing 2a and the rear housing 2b are fitted to form the main body 2 so as to sandwich the extension pillar 8a of the elbow member 8 by the raised portion of the front housing 2a and the rear housing 2b. As a result, the elbow portion 8 does not come out of the main body portion 2 (particularly the fishing portion) and can rotate in the left-right direction. That is, the elbow member 8 rotatably supports the base end portion of the extension portion 4 with respect to the main body portion 2 in the vertical direction.

Further, the massage machine 1 of the present invention has a structure in which a pair of left and right extending portions 4 are rotatably connected to the main body portion 2 in a horizontal plane as described above. Therefore, the extension portion 4 can be opened or closed between the states of FIGS. 1 and 2. Further, according to the connecting portion 7 of the present invention, the extending portion 4 can be opened or closed so that the state of FIGS. 1 and 2 and the state of FIG. 7 can be freely changed. it can. FIG. 7 shows a situation similar to a state in which the vines of the spectacles are closed, in which the left and right extending portions 4 can be arranged so as to be folded over the main body portion 2, and the massage machine 1 itself can be arranged. It is possible to make it very compact.

The structure of the connecting portion 7 is not limited to the hinge structure as long as it is connected so that the angle of the extending portion 4 with respect to the main body portion 2 can be changed.
As shown in FIG. 4 and the like, the main body 2 of the massage machine 1 is provided with a massage mechanism for performing a massage on the treatment target portion (affected portion) of the user U. In the case of the present invention, the configuration and structure of the massage mechanism are not limited, and a vibrator mechanism may be adopted, or a mechanism for generating a striking force may be adopted.

In the case of this embodiment, the massage mechanism has the following configuration.
The massage mechanism has a pair of left and right massage portions 3 for applying a striking massage to a treatment portion such as a shoulder portion. The massage portion 3 moves in and out at high speed back and forth through the opening 2c of the front housing 2a, so that a striking massage can be performed on the treatment target portion (affected portion) such as the shoulder portion.

The massage portion 3 is made of rubber, resin, or the like having appropriate softness, and has a chevron shape protruding forward. 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.
Further, the massage mechanism has a drive mechanism.

The drive mechanism 7 includes a drive shaft that eccentrically supports the end portion of the swing arm portion 14 on the base side, a drive motor 11 that rotationally drives the drive shaft, and the swing arm portion 14 is an opening of a mechanical storage portion. It has a steady rest member 12 that prevents unnecessarily runout in the portion. The steady rest member 12 can apply an elastic force to the swing arm portion 14 in a direction of pulling it back into the mechanical storage portion, and the massage portion 3 is provided at the tip of the swing arm.

Corresponding to the pair (two) of the swing arm portions 14, the drive shaft and the steady rest member 12 are also provided separately (pair).
First, the drive mechanism is attached in a hanging shape from the front housing by a support pillar, and drive motors 11 are arranged at the left and right centers of the drive mechanism. Motor shafts project from the drive motor 11 on both sides in the left-right direction, and a worm gear is formed at the tip of each motor shaft, and a speed reducer configured by meshing the worm gear with the worm wheel is provided.

A deceleration output shaft is provided so as to project in the front-rear direction from this speed reducer (worm wheel).
A disc-shaped cam plate is integrally rotatable on the deceleration output shaft. The base end of the swing arm portion 14 is fitted into the cam plate so that the peripheral edge of the cam plate can be slid, and the drive motor 11 rotates, and as a result, the deceleration output shaft rotates, so that the cam The plate rotates eccentrically, and the swing arm portion 14 moves eccentrically accordingly.

A massage portion 3 is attached to the tip of the swing arm portion 14, and a steady rest member 12 formed of a plate-shaped elastic body (rubber body) is attached to the massage portion 3. The tip of the steady rest member 12 is fixed to the bottom of the massage portion 3, and the base end of the steady rest member 12 is L-shaped so as to face outward as shown in FIG. 5, and the rear housing It is designed to be screwed to a fixed portion provided in a protruding shape inside the housing.

Therefore, the steady rest member 12 expands and contracts in the front-rear direction due to the eccentric movement of the swing arm portion 14, and lateral swing in the orthogonal direction thereof is prevented. Due to this expansion and contraction, the swing arm The portion 14 only performs eccentric movement in the anteroposterior direction, and thus the massage portion 3 exercises only in the anteroposterior direction through the opening 2c formed in the front housing 2a.

Next, the operation when the drive mechanism is driven will be described. When the drive motor 11 is operated by turning on the operation switch (operation unit 5), the deceleration output shaft rotates via the speed reducer, and the cam plate rotates eccentrically due to the rotation of the deceleration output shaft. Therefore, the end portion of the swing arm portion 14 on the base portion side rotates eccentrically around the deceleration output shaft.
Here, the swing arm portion 14 is guided by the steady rest member 12 connected via the massage portion 3 so that the swing arm portion 14 does not swing in any direction other than the predetermined direction. That is, the swing arm portion 14 is operated only in the direction of moving in and out of the opening, but is prevented from swinging laterally in the direction orthogonal to the opening.

By such an movement of entering and exiting the massage unit 3, a tapping operation is given to the treatment unit. Specifically, regarding the massage units 3 provided in pairs on the left and right, each massage unit 3 operates so as to move in and out (advance and retreat) alternately on the left and right.
A method of using the massage machine 1 having the above structure will be described.
As shown in FIGS. 8A to 8C, when the user U massages the neck and shoulders, the massage part 3 is applied to the shoulders and neck muscles which are the treatment parts, and the extension part 4 is placed from the side to the front of the neck of the user U. Make it protrude to. That is, the right extension portion 4 passes over the right shoulder of the user U and extends forward, and the left extension portion 4 passes over the left shoulder of the user U and extends forward.

At this time, in order to stabilize the massage machine 1 itself, it is preferable to grip the grip portion at the tip of the extension portion 4 with each hand so as not to shake up and down. After grasping, the extension portion 4 is pulled forward, and the massage portion 3 is strongly applied to the treated portion (affected portion of the neck and shoulder portion).
Then, in the massage machine 1 of the present embodiment, since both the main body portion 2 and the extension portion are made of synthetic resin having a certain degree of rigidity, the force when grasping and pulling forward is directly applied to the neck. In addition to the shoulders, a stronger tapping massage can be achieved on the neck and shoulders.

Further, in the massage machine 1 of the present embodiment, although the connecting portion 7 can swing, the main body portion 2 and the extending portion are hardly elastically deformed. Therefore, the massage portion 3 of the main body portion 2 can be pressed more accurately against the neck and shoulders than when the extension portion 4 is formed of an elastic member.
From the above, in the massage machine 1 of the present embodiment, the massage part 3 can be strongly pressed against the treatment part of the neck and shoulders without removing the acupuncture points, and a good massage feeling is provided to the user U. can do.

The massage machine 1 of the present embodiment is not always used in a usage mode in which the neck and shoulders are treated.
For example, as shown in FIGS. 9A to 9C, when the user U massages the lumbar region, the massage portion 3 is applied to the treated portion of the lumbar region, and the extension portion 4 is passed forward through the side of the body of the user U. Make it protrude. That is, the right extension portion 4 passes through the right side of the user U and extends forward, and the left extension portion 4 passes through the left side of the user U and extends forward.

At this time, in order to stabilize the massage machine 1 itself, it is preferable to grip the grip portion 6 (grip portion) at the tip of the extension portion 4 with each hand. After grasping, the extension portion 4 is pulled forward, and the massage portion 3 is strongly applied to the treated portion.
By doing so, as in the case of FIGS. 8A to 8C, the massage part 3 can be pressed strongly against the treatment part of the lumbar region without removing the acupuncture points, and the user U can obtain a good and effective massage feeling. Can be provided to.

In the massage machine 1 of the present embodiment, as shown in FIGS. 10A to 10C, when the user U massages the back and the upper part of the arm, the massage part 3 is applied to the treated part and the extension part 4 is applied. It can also be slanted. That is, the right extension portion 4 passes through the right side of the user U and extends forward, and the left extension portion 4 passes over the left shoulder of the user U and extends forward (conversely, The right extension 4 may pass over the right shoulder of the user U and extend forward, and the left extension 4 may pass the left side of the user U and extend forward). Since the extension portion 4 is rotatable with respect to the main body portion 2 by the connecting portion 7, the massage machine 1 can take such a form.

Specifically, the connecting portion 7 is rotatable outward by about 100 ° to 180 °, based on the state in which the temples of the eyeglasses are closed. In order to prevent the legs from being opened beyond this angle, stopper portions are formed on the base end side (elbow member 8) of the pair of connecting portions 7.
Therefore, when the extension portion 4 is rotated to the maximum with respect to the main body portion 2, the extension portion 4 on the left side, the main body portion 2, and the extension portion 4 on the right side are aligned substantially in a straight line, and the massage machine The length of 1 can be extended up to about 3 times as compared with the folded state. Therefore, the massage machine 1 of the present invention can provide the user with a satisfactory massage even in a usage mode in which treatment is difficult unless the posture is stretched like a diagonal cliff.

At this time, in order to stabilize the massage machine 1 itself, it is preferable to grip the grip portion 6 at the tip of the extension portion 4 with each hand. After gripping, the extension portion 4 is pulled forward and the massage portion 3 is strongly applied to the treatment portion, so that an effective tapping massage can be realized.
When the extension portion 4 is formed of an elastic member (in the case of the conventional massage machine 1), the extension portion 4 is elastically deformed even if the massage portion 3 is pressed against the treatment portion in a slanted state. , The contact of the massage part 3 with the treatment part is inevitably weakened.

However, if the extension portion 4 having rigidity is connected to both ends of the main body portion 2 as in the present embodiment, the massage portion 3 is accurately and strongly pushed to the treated portion even in a slanted state. It can be applied and can provide a good and effective massage feeling to the user U.
Even when the above-mentioned treated portion is treated, if one of the left and right treated portions is to be massaged particularly strongly, the massage machine 1 can be used in the posture shown in FIG.

That is, when the massage machine 1 is used as a reference in the states of FIGS. 8A to 8C, one of the left and right massage portions 3 provided on the main body portion 2 is shifted toward the front of the body and the other. The massage part 3 of the body is shifted toward the back of the body. That is, the left and right massage portions 3 are deployed so as to straddle the body of the user U back and forth. At this time, the massage unit 3 shifted to the front is biased toward the end in the left-right direction, and the massage unit 3 shifted to the rear is biased toward the rear (more central side in the left-right direction) of the user U. Take.

With the arrangement of the massage unit 3 as described above, the massaged portion can be massaged so as to be sandwiched between the front and back or the left and right, and a stronger massage can be performed on the treated portion.
Finally, as shown in FIG. 7, in the massage machine 1 of the present embodiment, when stored (when not in use), the extended portion 4 is bent so as to overlap the main body portion 2 and closed (the vine of the glasses (glasses)). The temple) can be folded). Since the extension portion 4 is rotatable with respect to the main body portion 2 by the connecting portion 7, the massage machine 1 may take a housing form in which the extension portion 4 is folded with respect to such a main body portion 2. It is possible. By closing the legs so that the extension 4 is folded in this way, the massage machine 1 becomes a very compact shape and can be stored anywhere regardless of the storage location, which makes the massage machine 1 more convenient. Further improve.

That is, the massage machine 1 of the present invention can be compactly accommodated by rotating the extension portion 4 with respect to the main body portion 2 by the connecting portion 7 to greatly change the length between the grip portions 6. However, it is possible to perform a massage in a posture like a diagonal cliff.
As described above, according to the massage machine 1 according to the present embodiment, even if the location of the affected area and the physique of the user U are different, one massage machine 1 can effectively massage various parts. it can. Specifically, not only the neck and shoulders can be effectively massaged, but also the waist and thighs can be effectively massaged.

The massage machine 1 according to the present invention is not limited to the neck / shoulder portion and the waist portion of the user U, but can also be used for the legs of the user U and the like. In addition, when stored (when not in use), it has a very compact shape and is easy to store.
