The advancing / retreating operation unit 16 of the advance / retreat mechanism 15 includes a link member 20, a rotation limiting unit 21, a drive unit 22, and rolling wheels 23.

A pair of right and left (two) link members 20 are provided, a stationary pivotal support portion 40 provided at the lower portion of the seat portion 2 (inward in the left-right direction on the upper side of the leg frame 6), and an upper rear portion of the foot massage device 5 (moving frame 30). The upper support portion 29 is provided so as to be connected to the movable support portion 41 provided at the upper end portion of the rear support frame 29. The stationary pivot portion 40 and the movable pivot portion 41 are configured to hold the link member 20 so as to be relatively rotatable around a pivot axis whose axis is directed in the left-right direction. Therefore, the link member 20 is configured such that the movable pivot 41 is swingable in the front-rear direction with the stationary pivot 40 as a fulcrum.

Regarding the forward / backward swing of the link member 20, the link member 20 can swing back and forth corresponding to the range in which the foot massaging device 5 moves from “storage position P to second use position U 2” (link member). 20 movable swing regions). That is, when the foot massage device 5 is located at the storage position P (see FIG. 2A), the link member 20 is located on the rear side of the movable swing region, and the foot massage device 5 is in the second use position U2. When the link member 20 is positioned at (see FIG. 2D), the link member 20 is positioned at the front side of the movable swing region.

In addition, the swinging region of the link member 20 thereafter (see FIGS. 2D and 2E) has a function of restricting the rotation of the foot massaging device 5 around the moving pivot 41.
Specifically, a pair of left and right abutment pins 44 are opposed to the link member 20 so as to protrude inward in the left-right direction from the vicinity of the movable support portion 41 (in a direction toward the link member 20 on the other side to be squared). It is a projecting project.

That is, these contact pins 44 do not come into contact with each other when the link member 20 swings in the range shown in FIGS. 2A to 2C. When the link member 20 swings within the range shown, it engages with the moving frame 30 (back support frame 29) that supports the foot kneading device 5.
The drive unit 22 applies a driving force that swings back and forth to the link member 20, and includes a rail unit 47, a back and forth moving body 48, and a driving mechanism 49.

As shown in FIG. 1 and FIG. 8, the rail portion 47 is a lower portion of the seat portion 2 (upper side in the leg frame 6), and a longitudinal direction is directed back and forth at a position above the storage position P. Is provided. In addition, a pair of left and right (two) rail portions 47 are provided in parallel with each other at a predetermined interval in order to open a position directly above the storage position P.
In the illustrated example, the groove-shaped strip material having a U-shaped cross section is attached so that the groove opening faces inward in the left-right direction (so that the two rail portions 47 are opposed to each other). A rail surface is formed.

The longitudinally moving body 48 is held so as to freely move back and forth along the rail portion 47, and is positioned below the seat portion 2 (upper side in the leg frame 6) and above the storage position P. Move in the direction.
As described above, in this embodiment, a pair of left and right rail portions 47 are provided at predetermined intervals, so that the longitudinally moving body 48 includes left and right sliders 50 that engage with the left and right rail portions 47. The slider 50 has a transition member 51 for connecting the sliders 50 to each other.

The slider 50 is formed in a square pipe shape whose longitudinal direction is directed in the front-rear direction, and is fitted into the rail portion 47 so as to be smoothly slidable.
In addition, the crossover member 51 has a shape in which the left and right end portions 51a are enlarged and extended in the front-rear direction in order to increase the connection strength with the left and right sliders 50, and is thinned in order to reduce the weight in the center portion in the left-right direction. Is formed.

With respect to such a longitudinally moving body 48, a portion near the left and right ends (front end portion of the slider 50) and a portion near the one end portion of each of the left and right link members 20 (the stationary pivot support portion 40 in each link member 20). Are connected to each other via a rotation fulcrum 53.
The driving mechanism 49 is for applying a driving force in the front-rear direction to the longitudinally moving body 48, and includes a feed screw shaft 55 provided in parallel to the rail portion 47, and an electric motor 56 that rotationally drives the feed screw shaft 55. And a nut portion 57 that is externally fitted to the feed screw shaft 55 in a screwed state. The nut portion 57 is provided in front of the transition member 51 of the longitudinally moving body 48 via a bracket 58.

A reduction gear 59 is connected to the electric motor 56, and the reduction gear 59 outputs an input from the electric motor 56 in a direction perpendicular to the plan view. The motor 56 is in a laterally arranged state. As a result, the driving mechanism 49 can be arranged in a compact manner in the front-rear direction.
As shown in FIG. 8, the crossover member 51 of the longitudinally moving body 48 is provided with a dent deforming portion 51 b at a position intersecting with the feed screw shaft 55 of the driving mechanism 49. The dent deformed portion 51b is formed by denting the installation direction (left-right direction) downward in order to avoid interference with the feed screw shaft 55.

The crossover member 51 of the front-rear moving body 48 is formed by recessing the installation direction (left-right direction) downward, similarly to the recessed deformation portion 51 b provided at a position intersecting the feed screw shaft 55 of the driving mechanism 49. The second dent deformed portion 51c is provided. This 2nd dent deformation | transformation part 51c is for avoiding interference with the reclining mechanism 8 (refer FIG. 1) for reclining the backrest part 3 with respect to the seat part 2. As shown in FIG.

By the way, in the case of this embodiment, the link member 20 mentioned above is made into a structure which can be expanded-contracted, and comprises the front protrusion operation | movement part 17 of the advance / retreat mechanism 15. FIG.
That is, the link member 20 is a combination of an arm main body 60 and a slide arm 61. The slide arm 61 is formed as an outer cylinder shaft, and the arm main body 60 is fitted into the slide arm 61 (outer cylinder axis). In addition, it is formed as an inner shaft (which may be a solid shaft or a hollow cylindrical shaft) that can slide in and out. The arm body 60 may be the outer cylinder shaft and the slide arm 61 may be the inner shaft.

A stationary pivot portion 40 is provided at the proximal end portion of the arm body 60 of the inner shaft, a moving pivot portion 41 is provided at the distal end portion of the slide arm 61, and the link member 20 and the front and rear sides are disposed on the proximal end side of the slide arm 61. A rotation fulcrum 53 that connects the moving body 48 is provided.
The operation mode of the chair type massage machine 1 having the above-described configuration, particularly the operation of the advance / retreat mechanism 15 will be described.

First, as shown in FIGS. 2 (A) and 3, it is assumed that the foot kneading device 5 is stored in the storage position P below the seat 2. At this time, the bottom surface of the foot massage device 5 is directed forward, the front surface (the surface provided with the holding

grooves

10 and 10 into which the user's lower limbs are fitted) is directed upward, and the bottom surface is the front end of the seat portion 2. It is almost flush with the part.
When the electric motor 56 of the drive unit 22 is operated, the moving pivotal support 41 swings forward with the stationary pivotal support 40 as the fulcrum of the link member 20 as the longitudinally moving body 48 moves forward. Therefore, as shown in FIG. 2 (B) and FIG. 4, a forward force is transmitted to the upper part of the back surface of the foot massage device 5, while the rolling wheel 23 rolls on the floor surface F, It advances smoothly and reaches the first use position U1 shown in FIG.

As the link member 20 is further swung forward, the rotation restricting portion 21 engages with the moving frame 30 (the rear support frame 29) with the stopper pin 44 that has not interfered anywhere before. The foot massaging device 5 is stopped from rotating around the movable support portion 41 (fixed so as to swing integrally with the link member 20). Thereafter, as the link member 20 is swung forward, the foot massaging device 5 floats the rolling wheel 23 on the floor surface F and moves to the second use position U2 shown in FIGS. 2 (D) and 6. Moving.

The foot massaging device 5 that has reached the second use position U2 is in a horizontal state in which the bottom surface faces the floor surface F, the bottom surface faces forward, and the front surface that massages the lower limb is substantially flush with the upper surface of the seat portion 2 or It is in a state where it faces upward while being connected in a gently sloping state with a front lowering.
If the user operates the lower limb massage mechanism with one foot inserted into the left and right holding

grooves

10, 10 with respect to the foot massage device 5, the user can comfortably receive massage. At this time, the foot massaging device 5 ascends as a whole and protrudes forward, so that the user can take a relaxed posture such as throwing the foot forward, and there is no need to bend the knee extremely. , To improve the feeling of use.

In addition, when it is desired to move the foot kneading device 5 further forward, the electric motor 56 of the drive unit 22 is continuously operated, and the longitudinally moving body 48 is further advanced.
Then, as shown in FIGS. 2E and 7, the arm main body 60 is in a state of being substantially parallel to the rail portion 47, so that the forward power of the longitudinally moving body 48 is slid through the rotation fulcrum 53. The slide arm 61 advances forward while sliding along the arm body 60. Due to the movement of the slide arm 61, the foot gripping device 5 pivotally supported at the tip of the slide arm 61 is further lifted above the floor surface F and further moved forward together with the slide arm 61. It advances to the 3rd use position U3 which makes a leg extensible massage possible.

Needless to say, the advancement of the foot massaging device 5 from the second use position U2 to the third use position U3 may be arbitrarily performed according to the user's preference.
On the other hand, if the electric motor 56 of the drive part 22 is reversely operated from the second use position U2, the link member 20 moves with the stationary pivot part 40 as a fulcrum as the longitudinally moving body 48 moves backward. Swings rearward, and the foot massaging device 5 moves from the second use position U2 to the storage position P via the first use position U1. When the foot kneading device 5 has been advanced to the third use position U3, the slide arm 61 is retracted with respect to the arm main body 60 before the link member 20 starts to swing backward. The foot massage device 5 is returned from the third use position U3 to the second use position U2.

As shown in FIG. 2 (C) → FIG. 2 (B) and FIG. 5 → FIG. 4, the foot kneading device 5 as a whole retreats the part protruding forward as the link member 20 swings backward. Then, it descends and further sinks the front upper part downward. As shown in FIG. 2 (B) and FIG. 4, when the rear upper part is lowered until the front upper part of the foot kneading device 5 becomes lower than the lower part of the seat part 2, the foot kneading apparatus 5 retreats with the lower part of the seat part 2 directed rearward. To come. At this time, since the rolling wheel 23 rolls on the floor surface F, the foot kneading device 5 moves smoothly.

Then, as shown in FIGS. 2A and 3, the foot massaging device 5 is returned to the state stored in the storage position P. A series of these operations is the retreat operation of the advance / retreat mechanism 15.
When the foot massage device 5 is placed in the storage position P, the bottom surface thereof faces forward and does not protrude from the front end portion of the seat portion 2, so that the “user who does not receive a massage” sitting on the chair type massage machine 1 While maintaining an easy posture, the appearance of the chair type massage machine 1 is simple and refreshing.

It should be noted that a sensor such as a limit switch is provided on the upper surface of the seat portion 2 or the holding groove 10 of the foot massage device 5 and the sensor detects the user, or the massage mechanism or the lower limb massage mechanism is It is preferable that the execution of the retreating operation is ignored when there is an operation for causing the advance / retreat mechanism 15 to perform the retreating operation during the operation.
