Description

  The present invention relates to a massage machine, and in particular, to prevent generation of rubbing noise caused by contact between a sheet metal treatment arm that supports a treatment element for treating a user via a fabric of a backrest portion and a back surface of the fabric of the backrest portion. It is related to the technology.

  2. Description of the Related Art Conventionally, there are known massage machines that can give a massage operation to a treatment element, and in particular, massage machines that can enhance the massage effect by shaking the treatment element to the left and right using a rotationally driven tilt axis. (For example, refer to Patent Document 1).

By the way, in the conventional massage machine, the treatment element unit provided with the treatment element which treats a user via the cloth of the backrest part, and the treatment arm made of sheet metal which supports this is accommodated inside the backrest part. The treatment element is treated by pressing the back of the user through the fabric of the backrest portion, but the treatment arm made of sheet metal has a structure in which the metal is exposed and directly rubs against the back surface of the fabric. For this reason, it has the subject that the rubbing sound of the back surface of a fabric and a treatment arm becomes large. Moreover, since the metal plate constituting the treatment arm is thin, the edge portion may break the fabric (for example, knit or nylon). In addition, there was a difficulty that it was difficult to attach a round to an edge part.

A high-quality massage machine can be easily obtained that can save the trouble of attaching and prevent the generation of rubbing noise and tearing of the fabric with a simple structure.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  FIG. 5A shows a chair-type massage machine 1 according to an embodiment of the present invention, and FIG. 5B shows a perspective view of the mechanism block 4.

  The massage machine 1 of this example is provided with a backrest part 3 facing substantially upward at the rear end part of the seat part 2, and a mechanism block 4 for performing a mechanical treatment operation is arranged in the backrest part 3 so as to be movable up and down. The treatment person sits on the seat portion 2 and is backrested on the backrest portion 3, and mechanical operations such as a hitting operation, a squeezing operation, and a back muscle stretching operation by the pair of left and right treatment element units 6 provided on the mechanism block 4. It is possible to perform a treatment operation. Each treatment element unit 6 includes a treatment arm 7 that is bent in a side view, and a pair of upper and lower roller-like treatment elements 8 (8a, 8b) attached to the upper and lower ends of the treatment arm 7, respectively. It has.

  As shown in FIGS. 5B and 6, the mechanism block 4 includes a pair of left and right gear plates 9, 9 (a width drive shaft 11, a slide guide shaft 12, and a tapping drive shaft 10 between the pair of gear plates 9, 9b. A pair of left and right treatment element units 6 (only one treatment element unit 6 is shown in FIG. 5B) is attached, and a tapping drive motor 13 is mounted on one gear plate 9. The output of the tapping drive motor 13 is transmitted to the tapping drive shaft 10 via the belt 30.

  The width driving shaft 11, the slide guide shaft 12, the hitting drive shaft 10, and the strength driving shaft are rotatably arranged in the mechanism block 4, and the hitting drive shaft 10 is eccentric at both ends. It is formed as a crankshaft having a shaft portion.

  The vertical drive unit 14 that drives the mechanism block 4 in the vertical direction (the X direction in FIG. 6) drives the vertical drive motor 14a, which is a drive source, to rotate forward or reverse, via a transmission mechanism (not shown). The shafts of the pinion and the traveling roller 20 are driven to rotate forward or backward at both ends, and along a vertical guide rail 40 (FIG. 2B) provided inside the backrest 3 of the massage machine 1. The traveling roller 20 is attached to be movable up and down, and a rack (not shown) formed on the vertical guide rail 40 is engaged with the pinion.

  When the width drive shaft 11 is rotationally driven by a width drive motor (not shown), the pair of left and right treatment element units 6 and 6 approach and separate from each other in the width direction (Y direction in FIG. 6), and the mechanism block 4 The interval between the left and right treatment elements 8a and 8b is changed. Realize so-called massage massage.

  On the other hand, when the tapping drive shaft 10, which is a crankshaft, is rotated by the tapping drive motor 13, the treatment arm 7 swings in the front-rear direction (θ direction in FIG. 6) and is attached to both ends of the treatment arm 7. The treatment elements 8a and 8b perform a tapping operation that moves back and forth finely.

  In addition, since the conventionally well-known technique disclosed, for example in Unexamined-Japanese-Patent No. 2007-14421 etc. can be used for the detail regarding the up-down operation | movement of the said treatment element 8, a kneading operation | movement, and a beating operation | movement, detailed description is abbreviate | omitted.

  Here, in the present invention, as shown in FIG. 1, a cap-like shape having sliding properties with respect to the back surface of the fabric 3 a is formed on the outer surface of the treatment arm 7 made of sheet metal in contact with the back surface of the fabric 3 a of the backrest portion 3. The sliding member 35 is externally mounted, and the attachment shaft 36 of the treatment element 8 is attached to the treatment arm 7 through the inner surface 35 a of the sliding member 35.

  As shown in FIG. 3, the treatment arm 7 made of sheet metal is bent in a square shape when viewed from the side, and sliding members 35 are externally mounted at both ends.

  The sliding member 35 is made of, for example, a resin molded product such as PP, is formed in a mountain shape that is slightly larger than the distal end portion of the treatment arm 7, and has a cap shape in which the skirt portion side is open. On the top side of the sliding member 35, a through hole that faces the shaft hole of the treatment arm 7 is provided. The size of the through hole is large enough to allow the attachment shaft 36 of the treatment element 8 to pass therethrough. The attachment shaft 36 of the treatment element 8 is attached to the treatment arm 7 by caulking. A screw hole is provided on the skirt side of the sliding member 35, and the screw hole of the sliding member 35 and the screw hole of the treatment arm 7 are screwed in a state where the sliding member 35 is put on the distal end portion of the treatment arm 7. Thus, the sliding member 35 can be attached to the treatment arm 7 without rattling.

  The backrest part 3 has a soft structure with elasticity, in which a cushion material having a thin uniform thickness is packed inside a bag-like cloth 3a. As shown in FIG. 2 (a) and FIG. 4 (a), a roller-shaped treatment element 8 is pressed. The material of the fabric 3a may be knit, nylon, jersey, or the like, for example.

  Therefore, by disposing the sliding member 35 on the treatment arm 7 made of sheet metal, it is possible to reduce unpleasant rubbing noise that occurs when the fabric 3a and the treatment arm 7 are rubbed. That is, by causing the sliding member 35 having a good sliding property to contact the back surface of the fabric 3a, the generation of rubbing noise can be prevented. In addition, when the attachment shaft 36 of the treatment element 8 is attached to the treatment arm 7 by caulking, an extra hook is likely to be generated on the outer surface side of the treatment arm 7 due to the caulking height. Excessive catching due to caulking does not occur, and as a result, in addition to preventing the generation of rubbing noise, the effect of preventing the fabric 3a from being broken by the edge portion of the treatment arm 7 made of sheet metal is also enhanced. As a result, the commercial value of the massage machine 1 can be easily increased.

  Further, by attaching the attachment shaft 36 of the treatment element 8 to the treatment arm 7 through the inner side surface 35a of the sliding member 35, the attachment member 36 of the treatment element 8 is simply attached to the treatment arm 7 so that the sliding member 35 is formed. Since it is attached to the treatment arm 7, it is not necessary to separately attach the sliding member 35 to the treatment arm 7, and the labor of the operation can be reduced.

  Moreover, in this example, as shown in FIG.3 (b), the smooth R is each chamfered in each edge part of the outer surface 35b of the sliding member 35, and the inner surface 35a. Here, chamfering is performed with a radius R that is more than half the thickness of the sliding member 35, and the radius R1 of the outer surface 35b is larger than the radius R2 (<R1) of the inner surface 35a, as shown in FIG. is doing. Thus, the fabric 3a can be protected by chamfering of the edge portion, and the occurrence of rubbing noise can be prevented and the fabric can be prevented by making the radius R1 of the outer surface 35b that is likely to hit the back surface of the fabric 3a larger than the radius R2 of the inner surface 35a. Each is effective in preventing the tearing of 3a.
