Description

  The present invention relates to a roller massager used for recovery from fatigue, health maintenance, beauty, and the like by rolling a rolling roller on the skin of the body to stimulate the skin.

  There are various types of massagers used for fatigue recovery, health maintenance, beauty, etc., including roller type and shiatsu type, friction type, belt type, pneumatic type, fluid pressure type, low frequency type, and a combination of these. There is. Among them, the roller type and the acupressure type are proposed in many types because they have a simple structure, are not easily broken, and can obtain a relatively large stimulus for a low running cost.

  For example, as the former roller type massager, a first fixed shaft and a second fixed shaft having flexibility are extended at both ends of a cylindrical base shaft, and the first fixed shaft and the second fixed shaft are respectively extended. A rotary hitting portion and a rolling portion having different shapes are rotatably mounted, and three plate-like plates are provided on the surface of a roller provided with a through-hole fitted into the first fixed shaft at the center of the rotary hitting portion. Mounted integrally, the plate is mounted with a metal wire around it, the other rolling part is made of ceramics, and consists of a roller with a through hole in the center, which is rotatably fitted to the second fixed shaft, A technique has been proposed that includes a cap / gripping portion that covers each of the rotary striking portion and the rolling portion (see Patent Document 1).

Further, as the latter acupressure massager, a plurality of rods are attached to the inner bottom of the massager body so as to be elastically output on the entire surface of the massager body, and a pair of rods are attached to both sides of the massager body. A magnetic body in which a handle is formed (see Patent Document 2) or a permanent magnet is provided in a socket opened at the end of a cylindrical case, and a part of the magnet is fitted in the socket so that the part is exposed to the outside A sphere formed by attracting and holding the sphere with the permanent magnet has been proposed (see Patent Document 3).

In this type of massage device, the pressing force on the massage device and the stimulation to the site where this acts are closely related. Since there is a side position relationship between the head and the rolling part, there is a drawback that the pressing force applied to the cap and gripping part is difficult to act on the rotary hitting part and the rolling part, particularly from the rotary hitting part consisting of three plates Not much stimulation was obtained.
In addition, since the massage device of Patent Document 2 requires a two-hand operation, the user himself can use the massage only for a few parts such as legs and feet. Furthermore, the massage device of Patent Document 3 has a drawback that only spot-like stimulation from a sphere can be obtained.

  The present invention has been made in the context of such a situation, and the purpose of the present invention is to efficiently stimulate a wide range of parts by allowing a user to roll a roller to a part of the body with his simple one-hand operation. Another object of the present invention is to provide a roller type massager that can be used and that can also perform a massage operation.

  In order to achieve the above-mentioned object, the present invention has a pair of main rollers arranged in parallel on both ends of a holder in which a flexible plate-like body is curved in an arc shape, and a sub-roller is provided inside the intermediate portion of the holder. In addition to being arranged in parallel with the main roller, a grip protrudes outside the intermediate portion of the holder.

  The holder of the present invention can be set so that it retains its original shape when the pressing force from the grip is small, and bends outward when the pressing force from the grip is large. Furthermore, the main roller of the present invention can be configured to include a cylindrical body that is rotatably supported by the holder via a support shaft, and a plurality of tapping plates provided in a tangential direction on the outer peripheral surface of the cylindrical body. Further, the hitting plate may be inclined so as to gradually become wider from one end side to the other end side and away from the central axis of the cylindrical body from one end side to the other end side.

The massager of the present invention massages a pair of main rollers or a pair of main rollers and sub-rollers onto the skin of a desired part of the body by grasping a grip provided outside the intermediate portion of the holder and applying a pressing force. To do. In particular, in the pair of main rollers, a plurality of striking plates disposed on the outer peripheral surface completely and strongly strike the skin at a desired site, so that a greater stimulation can be obtained.
Also, in a curved part larger than the curvature of the holder of the body or the curvature of the holder, only the pair of main rollers at both ends of the grip roll to stimulate the skin, and in a curved part smaller than the curvature of the holder of the body, The main roller and the sub roller roll to stimulate the skin.

  Further, according to the present invention, the holder is formed by bending a flexible plate-like body into an arc shape, so that the original shape is held when the pressing force from the grip is small, and outward when the pressing force from the grip is large. Can be bent. Accordingly, by applying strength to the grip, the bending shape of the holder can be expanded and contracted, and a body part can be sandwiched between a pair of main rollers or loosened.

Further, the main roller includes a cylindrical body that is rotatably supported by the holder via a support shaft, and a plurality of tapping plates provided in a tangential direction on the outer peripheral surface of the cylindrical body, thereby providing a plurality of sheets. Since the striking plate rotates to strike a part of the body, a greater stimulation can be obtained.
Further, the tapping plate is gradually widened from one end side to the other end side, and inclined from the one end side toward the other end side so as to be away from the central axis of the cylindrical body. The stimulation that acts on the body part is greater than that on one end of the striking plate. In addition to the rolling massage of the main roller, the squeezing operation that increases or decreases the pressure on the grip makes one end on the other end of the striking plate. Greater stagnation force than the side can be obtained.

  According to the massage device of the present invention, by pressing the grip provided on the outer side of the intermediate portion of the holder with one hand, the pressing force acts equally on the pair of main rollers provided on both side ends of the holder. The body part is stimulated, and the pressing force can be applied as a massage force to the body part without losing as much as possible. In addition, since the holder has a curved shape, different stimuli can be obtained by rolling the pair of main rollers or the pair of main rollers and sub-rollers depending on the portion to which the massager of the present invention is applied.

  Furthermore, the present invention holds the holder in its original shape by keeping the pressing force on the grip small, and performs a massage by rolling the above-described pair of main rollers or the pair of main rollers and sub rollers. In addition, it is possible to perform a rubbing operation such as pinching the body part between a pair of main rollers or loosening it by applying strength to the pressing force from the grip and bending the holder intermittently outward.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

The massaging device 1 shown in the basic diagrams of FIGS. 1 to 6 includes a pair of main rollers 3 and 3 arranged in parallel on both ends of a holder 2 that is curved in an arc shape, and a sub-roller 4 that is placed inside the holder 2 inside the main roller. 3 and 3, and the grip 2 a is integrally or fitted on the outer side of the intermediate portion of the holder 2.
The holder 2 is formed by bending a flexible synthetic resin plate-like body as a single unit in an arc shape as described above, or a reinforcing stainless steel plate or spring inside the flexible synthetic resin plate-like body. When the massage device 1 is used, it is possible to retain the original shape when the pressing force from the grip 2a is small, and to bend outward when the pressing force from the grip 2a is large. Yes. The grip 2a is substantially the same shape as the inner space when the palm is gripped by a synthetic resin that is the same as or slightly harder than the holder 2, and the upper surface of the grip 2a is used when the user uses the massage device 1. An arrow 5 indicating the direction of the heart is displayed.

  Roller mounting grooves 6, 6 opening outward and support arms 2 b, 2 b projecting at both ends of each roller mounting groove 6 are provided on both side ends of the holder 2. The roller mounting recess 7 and the support shaft holes 7a and 7a are provided, the pair of main rollers 3 and 3 are assembled using the roller mounting groove 6 and the support arms 2b and 2b, and the sub-roller 4 is mounted on the roller. The recess 7 and the support shaft holes 7a and 7a are used for assembly.

  Each of the main rollers 3 and 3 includes a cylindrical body 3a rotatably disposed in the roller mounting groove 6, and a support shaft (not shown) that protrudes from both ends of the cylindrical body 3a and is supported by the support arms 2b and 2b. And a plurality of tapping plates 3b provided in a tangential direction on the outer peripheral surface of the cylindrical body 3a, and a metal wire 8 provided so as to surround the outer peripheral surface of each tapping plate 3b. The sub-roller 4 has a cylindrical body 4a that is rotatably disposed in the roller mounting recess 7 with a smaller diameter than the cylindrical body 3a of the main roller 3, and has support shafts 4b and 4b that protrude from both ends of the cylindrical body 4a. By fitting into the holes 7 a and 7 a, a part of the cylindrical body 4 a is disposed so as to protrude outward from the inner surface of the holder 2.

  The cylindrical body 3a of the main roller 3 is formed in a tapered shape having a small diameter at one end side in the direction indicated by the arrow 5 and a large diameter at the other end side opposite to the direction indicated by the arrow 5. For this reason, the hitting plate 3b provided on the outer peripheral surface of the cylindrical body 3a is inclined outward from the one end side toward the other end side so as to be away from the central axis of the cylindrical body 3a. It is formed in a shape that gradually becomes wider from one end side to the other end side.

  7 and 8 show an example of use of the massage device 1 configured as described above. In use, it is necessary to start from a part far from the heart and gradually move it toward the heart. Less likely to interfere with blood flow.

  First, FIG. 7 shows an example in which the massage device 1 is used around the lower arm Ar of the user. In this use example, the massage device is applied while the pair of main rollers 3 and 3 are applied to the lower arm Ar of the user. 1 is reciprocated around the user's lower arm Ar, and the pressing force from the grip 2a is increased so that the plurality of hitting plates 3b of the main rollers 3 and 3 intermittently hit the user's lower arm Ar. At the same time, the holder 2 bends outward and the sub-roller 4 located on the inner surface also comes into contact with the user's lower arm Ar and massages.

In addition, the holder 2 is intermittently bent outward by applying strength to the pressing force from the grip 2a without reciprocating the massager 1 around the user's lower arm Ar, thereby lowering the user's lower arm Ar. When the holder 2 bends outward, the sub roller 4 also comes into contact with the user's lower arm Ar and massages.
As a modification of this kneading operation, the massage device 1 can be moved sideways while the holder 2 is bent outward with a strong pressing force and the main rollers 3 and 3 grip the skin. In this case, the hitting plate 3b of the main rollers 3 and 3 is used for hitting while changing the gripping position of the skin. The curved shape of the holder 2 is suitable for loosening the neck and shoulders.

  Further, when the massage device 1 shown in FIG. 7 is used, the arrow 5 of the grip 2a is directed toward the heart, one end side of the hitting plate 3b of the main rollers 3 and 3 is on the heart side, and the other end of the hitting plate 3b is Preferably, the sides are each placed on the opposite side of the heart. As described above, the hitting plate 3b is wider on the other end side than the one end side, and the other end side is inclined outward so as to be away from the central axis of the cylindrical body 3a. Therefore, the hitting plate 3b acts on the lower arm Ar. By making the tapping force act weakly on the heart side (one end side of the tapping plate 3b) and acting strongly on the side opposite to the heart (the other end side of the tapping plate 3b), the burden on the heart and blood flow are not hindered as much as possible. Like that.

  FIG. 8 shows an example in which the massage device 1 is used in the longitudinal direction of the user's lower arm Ar, and the pressing force acting on the holder 2 from the grip 2a is weak. In the original state, only the plurality of hitting plates 3b of the main rollers 3 and 3 perform massage by hitting the user's lower arm Ar intermittently.
