Description

  The present invention relates to a flexible massage machine that can easily and effectively massage a desired part such as a shoulder part, a neck part, a back part, a waist part, and a side part of a body.

  Conventionally, various massage machines have been developed and put to practical use as devices for massaging the body's shoulder, neck, back, waist, lower side, and the like. However, most of the massage machines that massage each part of the body are configured as one of the functions incorporated in the chair-type massage device.

  Moreover, the massage apparatus described in the following Patent Document 1 is used in such a state that the apparatus is hooked on the shoulder portion of the body and carried on the back portion. The structure also compresses the first massage means that performs massage while moving along the back of the body, the second massage means that compresses the shoulder of the body from the front and the back, and the neck of the body from the left and right. And third massage means.

  Therefore, the massage device of Patent Document 1 is designed to massage the shoulder, back, and neck by carrying the device on the shoulder, and the device is complicated and has a certain weight. For this reason, when this device is placed on the shoulder or back, there is a disadvantage that the weight of the device places a burden on the body, and further, the position where massage is performed cannot be freely changed.

  Furthermore, although the massage apparatus of patent document 1 is a structure which bears an apparatus on a shoulder part, it supports in the state which pressed each of said 1st massage means, 2nd massage means, and 3rd massage means to the body direction. Since there is no means, each massage means may not work efficiently.

  In addition, in the conventional chair-type massage machine, it is possible to press the back of the body against the massage machine by putting the back of the body on the massage machine provided on the back of the chair. Thus, it is impossible to support the back of the body in a pressed state.

Utility Model Registration No. 3087864

  Unlike the above-described conventional apparatus, the present invention can be held and handled, and it is possible to massage desired parts such as the shoulder, neck, back, waist and side of the body with a simple operation. In addition, an object is to provide a flexible massage machine capable of adjusting a pressing force while applying a pressing force to a body part desired to be massaged by a simple operation.

  In order to achieve the above object, the flexible massage machine according to claim 1 of the present invention has a plurality of vibrators arranged at predetermined intervals, and between the openings formed on both sides of each vibrator. A pair of bearing support portions are formed at intervals in the center, and an unbalancer made of a weight having an eccentric shaft is provided between the pair of bearings provided on each of the bearing support portions. The bearings that are coaxial in the bearings on both sides are connected by a flexible shaft that bends flexibly between each transducer, and the end of the protective tube that protects the outer periphery of the flexible shaft between each transducer is opened by each transducer One end of the entire length of the flexible shaft is rotatably coupled to the handle member, while the other end of the entire length of the flexible shaft By bound to a motor accommodated in the handle also serves case, Ann balancer in each transducer is characterized in that so as to eccentrically rotated by a motor in the handle also serves casing.

  A flexible massage machine according to a second aspect of the present invention is the flexible massage machine according to the first aspect, wherein the flexible shaft provided between the vibrators and the protective tube that protects the flexible shaft are bent with the same curvature radius and the same hardness. By adjusting the thickness, each flexible shaft is bent in a state where it does not contact the inner peripheral surface of each protective tube.

  A flexible massage machine according to a third aspect of the present invention is the flexible massage machine according to the first or second aspect, wherein the unbalancer provided in each vibrator and a bearing portion coaxial with the bearings on both sides thereof are flexible shafts between the vibrators. The coupled structure is characterized in that a wire shaft formed by one wire inserted through the shaft hole of the bearing portion is fixed by a set screw screwed from the outer periphery of the unbalancer toward the shaft hole of the bearing portion. And

  A flexible massage machine according to a fourth aspect of the present invention is the flexible massage machine according to the first or second aspect, wherein the unbalancer provided in each vibrator and the bearing portions that are coaxial with the bearings on both sides thereof are flexible shafts between the vibrators. The combined structure is formed by a shaft that protrudes on both sides of a bearing unit formed integrally with each unbalancer, and is rotatably supported by each bearing, and a flexible spring is formed on each shaft on both sides. It is connected with a spring shaft.

  According to a fifth aspect of the present invention, there is provided a flexible massage machine according to the first or second aspect, wherein the unbalancer provided in each vibrator and a bearing portion coaxial with the bearings on both sides thereof are flexible shafts between the vibrators. The combined structure is such that the shaft portions projecting on both sides of the bearing portion formed integrally with each unbalancer are rotatably supported by each bearing, and the shaft portions on both sides are made of rubber or elastomer having flexibility. It is characterized by being connected by a formed shaft.

  Since the flexible massage machine of the present invention is configured as described above, the use method thereof is to hold the handle member provided on both ends of the flexible shaft and the handle combined case with one hand of the user. Drive the motor in the handle / case while keeping the length of the flexible shaft stretched with the force of the arm and placing each transducer on the shoulder, neck, back, waist, side of the body, etc. To do.

  When the flexible shaft rotates by driving the motor as described above, the unbalancer in each vibrator rotates eccentrically, and vibration is generated in each vibrator. At this time, it becomes possible to finely adjust the pressing force of each vibrator applied to the body part by grasping the handle member and the handle combined case with each hand of the user and pulling it in the direction of stretching the flexible shaft. . In addition, the vibration generated in each transducer in such a state massages the desired parts such as the shoulder, neck, back, waist, and the lower part of the body, thereby relaxing the stiffness and promoting blood circulation and recovering from fatigue. It becomes possible to do.

  As described above, the present invention can finely adjust the tension of the handle member and the handle-combined case gripped by the user's respective hands with the force of the user's arm, and the user's hand operation. It is possible to finely adjust the part where each vibrator hits the body. For this reason, with a very simple configuration and handling, it is possible to give the massage effect of the vibrator to the back of the body which is usually difficult to reach.

  Further, in the present invention, the flexible shaft provided between the vibrators and the protective tube that protects each flexible shaft are bent with the same radius of curvature so that the rotating flexible shaft is the inner peripheral surface of the protective tube.
