Description

  The present invention relates to a chair type massage machine.

  Conventionally, it has a chair body that is provided with a backrest portion that can be tilted to the rear of the seat portion and armrest portions on both outer sides of the seat portion, and massage treatment is performed on a user seated on the chair body. There is known a chair type massage machine to be applied (for example, see Patent Document 1).

  By the way, in recent years, chair-type massage machines have a tendency to increase the width of the chair body that accommodates massage devices due to an increase in the number of treatment sites and multifunctionality in massage treatment. There have also been situations such as being unable to pass through the opening of the building when being carried into the building.

Here, the width dimension (width) of the chair type massage machine is determined by the armrests disposed on both outer sides of the seat. Therefore, when it is necessary to narrow the width of the chair type massage machine, such as when passing through the opening, the armrest portion must be removed from the chair body. In other words, in this measure, it is not only troublesome to remove and attach the armrest from the chair body, but also mounting errors such as attaching the removed pair of armrests to the chair body in the opposite direction. The chair-type massage machine that makes it possible to cope with this problem is eagerly desired.

  This invention is made | formed in view of said point, The place made into the objective makes it a subject to provide the chair type massage machine which can narrow a width | variety, without removing an armrest part.

  In order to solve the above-mentioned problem, in the chair type massage machine according to claim 1, the chair type massage machine for performing massage treatment on the user who is seated on the seat portion 3 provided with the armrest portions 6 on both outer sides. 1, width reduction means 10 is provided that enables the outer end position of the armrest portion 6 to be changed inward while maintaining the attached state.

  According to this, the outer end position of the armrest portion 6 can be changed to the inner side without removing the armrest portion 6 by the width reducing means 10, and it is not necessary to remove and attach the armrest portion 6, for example, when passing through the opening. The width A of the chair type massage machine 1 can be narrowed.

  Moreover, in the chair type massage machine which concerns on Claim 2, the armrest part 6 is provided with the elongate elbow mounting member 8 by which the upper surface becomes the elbow mounting surface 8a in the armrest part 6, The said elbow mounting member 8 is provided. The width reducing means 10 is constituted by a rotation posture changing mechanism 11 that rotates around the longitudinal axis.

  According to this, it is possible to narrow the width A of the chair type massage machine 1 while the elbow rest member 8 of the armrest portion 6 is positioned substantially on the spot by the rotation posture changing mechanism 11, and the operation of the armrest portion 6. Space can be reduced and space saving of the chair type massage machine 1 can be achieved.

  In the chair type massage machine according to claim 3, the armrest portion 6 is the elbow rest member 8 on the upper portion of the vertical wall-shaped armrest base portion 7 provided along the outside of the seat portion 3. And the elbow rest member 8 can be positioned inside the outer surface 7a of the armrest base 7 by the width reducing means 10.

  According to this, when the width A of the chair type massage machine 1 is narrowed, the armrest base 7 having a vertical wall shape can be positioned on the outermost side of the chair type massage machine 1, so that the chair can be used when passing through the opening. Even if an external force is applied to the massage machine 1 from the outside, the external force is applied to the relatively sturdy vertical wall-shaped armrest base 7, and the chair-type massage machine 1 can be prevented from being damaged. .

  In this invention, it has the advantage that the width | variety of a chair type massage machine can be narrowed at the time of passage of an opening part, etc., without being accompanied by the removal and attachment operation | work of an armrest part.

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

  As shown in FIG. 2, the chair-type massage machine 1 of the present example includes a backrest part 4 that can be tilted behind the seat part 3 and a footrest part 5 in front of the seat part 3. A chair body 2 having armrests 6 is provided on both left and right outer sides, and massage treatment is performed on a user seated on the chair body 2. Although not shown in particular, the backrest part 4 is internally provided with a treatment element drive unit that performs pressure massage with squeezing and striking with a treatment element that is driven against the back part of the user, such as a seat part 3 and a footrest part. 5 is equipped with an airbag drive unit that performs compression massage with an airbag that expands and contracts with respect to the legs of the user. The chair body 2 is provided with a body frame that forms the skeleton, and the seat portion 3, the backrest portion 4, the footrest portion 5, and the armrest portion 6 are integrated with the body frame. Although not particularly illustrated, the main body frame is provided with an expansion / contraction mechanism and a link, and the backrest portion 4 and the footrest portion 5 can be tilted by the expansion / contraction mechanism and the link. The width A (left and right maximum width dimension) of the chair type massage machine 1 is the dimension between the outer ends of the pair of armrests 6.

  The armrest portion 6 includes a vertical wall-shaped (vertical wall-shaped) armrest base portion 7 provided along the outside of the seat portion 3 and an armrest member 8 attached to a support leg portion 9 protruding upward from the armrest base portion 7. It is configured. The surface of the armrest base portion 7 is formed in a flat shape without unevenness, and the support leg portion 9 is constituted by a part of the main body frame passing through the armrest base portion 7. The elbow rest member 8 has a flat semicircular cross section with the upper surface serving as an elbow rest surface 8a, and is formed of a rod-like member that is formed long in the front-rear direction. The left-right width dimension of the elbow rest member 8 is the largest in the left-right width dimension L of the elbow rest surface 8 a, and the left-right width dimension L of the elbow rest surface 8 a is longer than the vertical dimension H of the elbow rest member 8. Has been. The rear region of the elbow rest member 8 overlaps with the backrest portion 4 in a side view so that the elbow of the user drowning on the reclining backrest portion 4 can be comfortably placed, that is, the backrest portion. 4 is arranged so as to be located on both the left and right outer sides.

  Here, in the chair type massage machine 1 of this example, in order to be able to narrow the width A (maximum left and right width dimension) as appropriate, the outer end position of the armrest portion 6 can be changed inward while maintaining the attached state. Width reduction means 10 is provided. Specifically, a rotation posture changing mechanism 11 that rotates the elbow rest member 8 around its longitudinal axis is employed as the width reducing means 10 of this example. The rotation posture changing mechanism 11 of this example is a structure in which the lower end portion of the elbow rest member 8 is pivotally supported on the upper portion of the support leg portion 9 via a pivot shaft in the length direction (front-rear direction) of the elbow rest member 8. As shown in FIGS. 1 (a) and 2, the substantially horizontal elbow resting surface 8a facing upward during normal use is as shown in FIGS. 1 (b) and 3 when the posture is changed (when the width is changed). The posture can be changed so as to be substantially vertical and face the seat 3 side (left and right center side). In more detail, the elbow rest member 8 has a portion slightly inward in the left-right width direction pivotally supported by the support leg 9. In normal use, the elbow rest member 8 has an outer end at the outer surface of the armrest base 7. The mounting piece 8b, which is positioned so as to protrude outward from the lower end 7a and hangs downward from the lowermost end of the elbow rest member 8, is brought into contact with the outer surface 9a of the support leg 9 and fixed with screws. On the other hand, when the width is changed, the elbow rest member 8 is positioned inward of the outer surface 7a of the armrest base 7 as shown in FIG.

  Thus, in the chair type massage machine 1 of this example, the outer end position of the armrest portion 6 can be changed to the inner side without removing the armrest portion 6 by the width reducing means 10, and the work for removing and attaching the armrest portion 6 is involved. In other words, the width A of the chair type massage machine 1 could be narrowed when passing through the opening.

  Further, according to the rotation posture changing mechanism 11 that rotates the elbow rest member 8 adopted as the width reducing means 10 around its longitudinal axis, the elbow rest member 8 whose rear area overlaps the backrest section 4 in a side view is substantially the same. The width A of the chair-type massage machine 1 can be narrowed while the chair-type massage machine 1 is kept in place, that is, the operation space of the armrest portion 6 is reduced, and space saving of the chair-type massage machine 1 is achieved. is there.

  Further, when changing the width of the armrest 6, the elbow rest member 8 is positioned inward of the outer surface 7 a of the armrest base 7 as described above, that is, when the posture of the armrest 6 is changed (width) At the time of change), the armrest base 7 having a vertical wall shape is positioned on the outermost side of the chair type massage machine 1, and an external force is applied to the chair type massage machine 1 from the outside when passing through the opening. However, the external force is applied to the outer surface 7a of the relatively strong vertical wall-shaped armrest base 7, and the chair-type massage machine 1 is prevented from being damaged.

  Although not specifically shown, the width reducing means 10 is constituted by a slide mechanism that can slide to the left and right by sliding the elbow rest member 8 on a guide rail provided on the support leg 9, for example. You can also Moreover, in the said embodiment, although the pivot support structure which pivotally supported the elbow rest member 8 with the pivot shaft which does not move with respect to the support leg 9 as the rotation attitude change mechanism 11 was illustrated, as the rotation attitude change mechanism 11, For example, a sliding-type rotation posture changing mechanism is adopted in which the pivot shaft that pivotally supports the elbow rest member 8 and the support leg 9 also slides inward in conjunction with the pivoting operation of the elbow rest member 8. You can also.
