[overall structure]
The massage machine 1 according to the first embodiment is a multi-type massage machine that is used by applying each of the massage members 4 to 6 to be described later to a desired treatment area. As shown in FIGS. 1 and 2, the massage machine 1 according to the first embodiment of the present invention mainly includes a base portion 2, a rotating shaft 3 that rotates by driving a motor 8, and a rotation of the rotating shaft 3. A pair of first massage members 4 that are close to and away from each other, a pair of second massage members 5 that are provided on the first massage member 4 and that operate in conjunction with the operation of the first massage member 4, and a pair that is supported by a rotating shaft. The third massage member 6 positioned between the first massage members 4 and 4 and the grip member 7 provided on the base portion 2 and gripped by the user. The base portion 2 supports a motor 8 and a rotary shaft 3 linked to the motor 8 via a speed reducer 9 so as to be rotatable. The base portion 2 includes the rotary shaft 3, the motor 8, the speed reducer 9, and the like. The drive mechanism 10 is protected by a housing 11. The casing 11 is provided with an operation unit 12 that allows the user to perform various operations. Moreover, each massage member 4-6 is covered with the cover member (not shown) which consists of cloth | dough etc. which have a stretching property, and massage is performed by each massage member 4-6 via this cover member.

In addition, the concept of the direction used in the following description is based on the case where the user's neck and shoulder are massaged simultaneously using the massage machine 1 of the present invention, and the axial direction of the rotary shaft 3 is the left-right direction (the left hand side is “left ”And the right hand side is“ right ”), the height direction of the user is up and down (the head side is“ up ”and the waist side is“ down ”), and the body thickness direction is the front and back direction (the chest side is“ front ”) And the back side is “rear”). In the left-right direction, the axial center side of the rotary shaft 3 is “inside” and the axial end side is “outside”.
Moreover, although the massage machine 1 of this invention can perform massage simultaneously or selectively with respect to a several treatment part, below, the 1st and 3rd massage members 4 and 6 are made into a neck (1st The second massage member 5 is applied to the shoulder (second treatment portion) and the neck and shoulder are massaged at the same time.

[Configuration of the first massage member]
As shown in FIGS. 1 to 3, the first massage member 4 includes a cylindrical hollow shaft 13 extending in the left-right direction, and a disk-shaped pressing disk 14 provided at the left and right inner ends of the hollow shaft 13. Have. The pressing disc 14 is rotatably connected to the hollow shaft 13 at the center thereof, and the axis C of the hollow shaft 13 and the axis of the pressing disc 14 are at a predetermined angle (for example, 10 The pressing disk 14 is oriented with respect to the hollow shaft 13 so as to form a degree. A plurality of treatment protrusions 14 b made of synthetic resin are attached to the surface (the left and right inner surfaces) 14 a of the pressing disk 14 facing the treatment portion along the circumferential direction of the pressing disk 14.

  As shown in FIG. 4, the hollow shaft 13 extending in the left-right direction from the pressing disk 14 included in the first massage member 4 is fitted into the rotating shaft 3. Therefore, the pair of first massage members 4 can be slid in the left-right direction, and the pair of first massage members 4 can approach and separate from each other. As shown in FIG. 2, the left and right end portions of the rotating shaft 3 are rotatably supported by bearing portions (not shown) provided on the base portion 2. The pressing disk 14 is fixed to the housing 11 while only allowing movement in the left-right direction via a second massage member 5 described later.

  In addition, spacers 15 are disposed on the left and right outer sides of the pressing disks 14 included in the left and right first massage members 4. The spacer 15 has a configuration in which one end of a cylindrical member having a slightly smaller diameter than the pressing disk 14 is cut obliquely, and is used to fill a gap on the left and right outer sides of the pressing disk 14. The spacer 15 is attached to the rotary shaft 3 so as to rotate integrally with the rotary shaft 3.

  A rotary shaft 3 for rotating the left and right first massage members 4 is provided in the internal space of the hollow shaft 13, and the rotary shaft 3 is spline-coupled to each hollow shaft 13. Accordingly, the hollow shaft 13 is movable independently of the rotating shaft 3 in the left-right direction along the axis C of the rotating shaft 3, but only integrally with the rotating shaft 3 in the circumferential direction of the rotating shaft 3. It can be rotated. As shown in FIG. 2, when the pair of first massage members 4, 4 are inserted through the rotary shaft 3, the inclination directions of the center axes of the pair of pressing disks 14, 14 with respect to the axis C are opposite to each other. I have to. Accordingly, there are a small part and a large part in the separation distance between the pressing disks 14 and 14 arranged opposite to each other.

  When the motor 8 is driven and the output shaft (not shown) rotates, the rotational power is transmitted to the rotary shaft 3 via the speed reducer 9 and rotates it. When the rotating shaft 3 rotates, the hollow shaft 13 splined with the rotating shaft 3 rotates integrally with the spacer 15. On the other hand, the rotational movement of the pressing disk 14 is regulated by a regulating member 16 attached to a second massage member 5 (described later) fixed to the pressing disk 14, and therefore the inclination of the spacer 15 is caused by the rotation of the spacer 15. The pressing disk 14 is pushed by the surface (right and left inner surfaces) 15a and moves in the left-right direction. More specifically, as shown in FIG. 6A, the pair of pressing disks 14 and 14 are inclined in opposite directions with respect to the axis C of the rotating shaft 3, and the upper sides are close to each other. The state (solid line state) and the state in which they are inclined in opposite directions with respect to the axis C of the rotating shaft 3 and the lower sides are close to each other (the state of the two-dot chain line) are alternately repeated. The spacer 15 also serves as a cam member that converts the rotational motion of the pressing disk 14 into left-right motion.

  Further, as shown in FIG. 6A, when the motor 8 is driven with the neck positioned between the left and right pressing disks 14 and 14 of the pair of first massage members 4, these pressing disks 14 rotates in contact with the side of the neck. Since the central axis of the pressing disc 14 is inclined by a predetermined angle with respect to the axis C, the left and right pressing discs 14 and 14 repeat approach and separation with respect to the neck as they rotate. This action becomes a squeaking action for the neck.

  Moreover, since the 1st massage member 4 can slide to right and left along the rotating shaft 3, according to the difference in the thickness dimension of a neck of a user, the separation of a pair of 1st massage members 4 and 4 is carried out. The distance is changed. Further, as shown in FIG. 2, a spring receiver 17 that is integrally attached to the rotary shaft 3 is provided on the left and right outer sides of the spacer 15, and a spring spring that is a biasing means is provided between the spring receiver 17 and the spacer 15. 18 is attached. The spring spring 18 biases the left and right pressing discs 14 and 14 inward in the left-right direction via the spacer 15 (that is, in a direction in which both are close to each other). Accordingly, the pressing disks 14 and 14 are pressed against the neck of the user by an appropriate pressing force generated by the biasing force of the spring spring 18.
