The cam surface of the cam 22 and the front surface of the pushing arm 16b abut.

As shown in FIG. 1, the action of contacting the cam surface of the cam 22 with the front side surface of the pushing arm 16b is performed by an elastic body 26.
The pushing force of the pushing arm 16b is brought into contact with the cam 22 by the urging force of the arm. That is, in the embodiment,
A support plate 24 is horizontally laid horizontally on the rear end edges of both support side plates 12, 12, and the elastic body 2 is disposed between the support plate 24 and the pushing arm 16 b.

6b serves as urging means for pressing the cam 6b against the cam 22, and an appropriate elastic body such as a coil spring can be used.

In the embodiment, the cam 22 is formed by an eccentric cam, and when the cam 22 makes one rotation, the pushing arm 16b
Is provided so as to swing once. The operation of the cam 22 is as follows.
That is, the rotation of the cam 22 causes the pushing arm 16b to swing. Therefore, the shape of the cam 22 is not limited to the eccentric cam as long as the pushing arm 16b is swung by the rotation of the cam 22. In the present embodiment, the cam 22 is arranged on the front side of the pushing arm 16b. However, the arrangement of the cam 22 and the elastic body 26 is reversed, and the cam 22 is placed on the rear side of the pushing arm 16b. It is also possible to adopt a configuration in which the contact is made. Motor 18, cam 2
2. The elastic body 26 constitutes a pushing mechanism for pushing the pushing arm 16b back and forth.

Subsequently, a method of using the massage device according to the present embodiment will be described. The massage device according to the present invention massages a hand, an arm, and the like by pinching a finger of a hand between a hook portion 28 and a holding portion 29 and swinging the hand up and down. First, the fingertip is supported by the fingertip holding mechanism A with the arm extended substantially horizontally. At this time, as shown in FIG. 3, the leading ends of the hooking portion 28 and the holding portion 29 contacted by the spring 34 are opened up and down, and a finger is inserted between the holding portions 28 and the fingertip is hooked on the hooking portion 28. 29 holds the fingertip.
The holding portion 29 elastically presses the fingertip by the elastic force of the spring 34. The force for pinching the fingertip can be appropriately adjusted by the adjusting screw 36.

The power of the motor 18 is turned on while the fingertip is sandwiched between the hooking section 28 and the holding section 29, and the swing mechanism B is driven. When the motor 18 drives the motor shaft 20 and the cam 22 fixed to the motor shaft 20, the cam 22 rotates.
The cam surface and the front side surface of the push arm 16b are always in contact with each other by the elastic body 26, so that the rotational movement of the cam 22 swings about the push arm 16b with the support shaft 14 as a fulcrum. The action of the cam 22 swinging the push arm 16b is the action of swinging the operating arm 16c vertically in the vertical direction by the "leverage principle" with the support shaft 14 as a fulcrum.
Since the fingertip holding mechanism A is supported at the tip of the operating arm 16c, the swing of the operating arm 16c causes the fingertip holding mechanism A to rotate.
And the entire fingertip holding mechanism A swings. Thereby, the fingertip of the hand supported by the fingertip holding mechanism A is swung, the swing of the fingertip is transmitted to the entire arm, and the entire arm and the shoulder are massaged for the swinging operation.

In the massage device according to the present invention, the action of swinging the hand up and down while supporting the fingertip of the hand becomes the action of swinging not only the hand but also the entire arm, and this swinging operation is performed from the arm to the shoulder. It is characteristic that the massage can be transmitted to the arm and shoulder part. Further, the swing of the operation arm 16c according to the present embodiment is not a simple vertical movement in the vertical direction, but the rotation of the operation arm 16c about the support shaft 14, so that the fingertip holding mechanism supported by the operation arm 16c. A is characterized by performing a circular motion. With this movement, the hand supported by the fingertip holding mechanism A is subjected to a movement of pulling the arm back and forth as well as a movement in the vertical direction. That is, the hand swings up and down while being pulled back and forth. Such an action of swinging the arm is extremely effective as a massage applied to the hand and the arm, and exerts a massage action different from a conventional massage device. In addition, the action of swinging the entire hand and arm relaxes the hand and arm, and can effectively relieve stiffness and the like.

Since the optimum swing amount and swing speed of the fingertip holding mechanism A differ depending on the user, the swing amount and swing speed of the fingertip holding mechanism A can be adjusted.
Further, an effective massage action can be obtained. The swing speed of the fingertip holding mechanism A can be appropriately set by adjusting the number of rotations of the motor 18 that drives the cam 22 to rotate. The swing speed of the fingertip holding mechanism A can be adjusted by providing a control unit for adjusting the rotation speed of the motor 18 and appropriately setting the speed by operating the control unit. If the rotation speed of the motor 18 is increased, the fingertip holding mechanism A moves up and down quickly, and if the rotation speed is reduced, the fingertip holding mechanism A moves up and down slowly. In addition, as a method of program-controlling the control unit, for example, it is possible to repeat the operation of moving the fingertip holding mechanism A up and down quickly for a certain time and then slowly moving it up and down for a certain time. Since the vertical movement of the fingertip holding mechanism A plays an important role in the massager according to the present invention, the ability to set various movements of the fingertip holding mechanism A is effective as an effective and easy-to-use device.

As a method of adjusting the swing amount of the fingertip holding mechanism A, a method of changing the swing width of the pushing arm 16b by using the cams 22 having different eccentric amounts, and a method of adjusting the cam 22 and the pushing arm 16b. A method of changing the swing width of the pressing arm 16b by changing the contact position is possible. When the same cam 22 is used, the cam 22 and the pushing arm 16b are used.
When the contact position of the push arm 16b with respect to the front surface of the push arm 16b is further away from the support shaft 14, the swing width of the pushing arm 16b becomes smaller, and the contact position of the cam 22 with the front surface of the push arm 16b approaches the support shaft 14. In this case, the swing width of the pushing arm 16b increases.
Therefore, it is also effective to make it possible to adjust the contact position between the cam 22 and the pushing arm 16b so that the swing amount of the fingertip holding mechanism A can be adjusted.

The massager according to the present invention is characterized in that a fingertip is supported by a fingertip holding mechanism A, and a hand is rocked up and down by a rocking mechanism B to massage. Therefore,
The fingertip holding mechanism A and the swinging mechanism B for swinging the fingertip holding mechanism up and down are not limited to the above-described embodiment. In the above embodiment, the cam 22 is brought into contact with the front side surface of the push arm 16b, and the push arm 16b is swung by the action of the cam 22, but, for example, the push arm 16b is used without using the motor 18 and the cam 22. It is also possible to use an air mechanism as the drive source that swings, connect the air cylinder to the lower end of the push arm 16b, and push the push arm 16b.

In the above embodiment, the fingertip holding mechanism A
Is formed integrally with the operating arm 16c by connecting the hooking portion 28 to the operating arm 16c. However, a fingertip holding mechanism A is provided separately from the operating arm 16c, and the fingertip holding mechanism A is attached to the operating arm 16c for use. Is also possible. Further, in the present embodiment, the fingertip holding mechanism A is configured to hold the finger between the hooking portion 28 and the holding portion 29, but the present invention is not limited to this configuration. For example, a method of holding a fingertip without using the holding portion 29 by forming a shape in which a fingertip is hooked and hooked on a tip portion of the hooking portion 28 shown in the present embodiment, an adhesive on the inner surface of the hooking portion 28 A method of providing a body and holding the fingertip using adhesive force, or extending the tip of the operating arm 16c flat to form a hook portion 28, and forming an upward projection on the hook portion 28 The function as the fingertip holding mechanism A can also be achieved by a method in which a plurality of fingers are provided at the width intervals of the fingers, the fingers are put between the projections, and the projections are held between the fingers to hold the fingertips. .

In the swing mechanism B, the operating arm 16c
Is formed of a material having some flexibility, and is configured so as to provide a cushioning property when the hand is swung up and down by supporting the hand by the fingertip holding mechanism A to reduce the shock acting on the hand and the arm. Is also possible. Further, the support shaft 14 itself is vertically moved up and down, so that the fingertip holding mechanism A
The circular motion is performed simultaneously with the vertical translation, and the massage can be performed by a more natural motion. In addition, by providing a plurality of joints on the operation arm 16c, various swings can be obtained and an effective massage is provided. The device of the above embodiment is provided with one fingertip holding mechanism A and one swing mechanism B, and is used by changing the left and right hands. However, the fingertip holding mechanism A and the swing mechanism B of the same form are used.
By providing two of them, it is also possible to adopt a configuration in which both hands can be massaged simultaneously.
