The rail member 50 will be described with reference to FIG. FIG. 3 is a perspective view of the right side rail member 50a. Since the left side rail member 50b is a mirror image of the right side rail member 50a, the illustration and description of the left side rail member 50b will be omitted.

In the example shown in FIG. 3, the rail member 50 is an elongated member having a bent portion between the front end and the rear end. The rail member 50 has an internal space which accommodates the traveling tool 32 provided on the seat frame 30. The traveling tool 32 is movable in the longitudinal direction of the rail member 50 while rotating in its internal space. The rail member 50 is formed with an opening 51 from the front end to the rear end so that the traveling tool 32 can move in the front-rear direction. The rail member 50 can be formed of a square member such as a C-shaped rigid material.

The rail member 50 has a traveling surface 52 on which the traveling tool 32 travels. In the illustrated example, the running surface 52 includes at least the lower inner surface of the inner surfaces defining the inner space of the rail member 50. The traveling surface 52 includes a first traveling unit 52a and a second traveling unit 52b each of which is linear. The second travel unit 52b is connected to the front end of the first travel unit 52a. The rail member 50 is formed to extend upward as the second traveling part 52b goes forward when the first traveling part 52a is disposed horizontally. Thus, the traveling surface 52 is bent. The bent portion of the rail member 50 corresponds to the connection portion between the first travel portion 52a and the second travel portion 52b. The first travel portion 52a may be referred to as a rear travel surface behind the bending portion, and the second travel portion 52b may be referred to as a front travel surface forward of the bending portion.

The rail member 60 has an internal space that accommodates the traveling tool 43 provided on the back frame 40. The traveling tool 43 is movable in the longitudinal direction of the rail member 60 while rotating in its internal space. The rail member 60 is formed with an opening 61 (see FIG. 2) from the front end to the rear end so that the traveling tool 43 can move. The rail member 60 has a traveling surface 62 (see FIG. 4) on which the traveling tool 43 travels. In the present embodiment, by forming the rail member 60 so as to be curved, the traveling surface 62 is largely inclined except for the rear end portion of the rail member 60. The rail member 60 can be formed of a square member such as a C-shaped rigid material.

In addition, the reclining chair 10 is configured so that the backrest 12 can be reclined electrically. In the present embodiment, as shown in FIG. 2, the electric expansion and contraction mechanism 70 is connected to the base frame 20 and the seat frame 30.

One end of the electric expansion and contraction mechanism 70 is connected to the connection frame 23 a of the base frame 20 via the expansion and contraction mechanism connection portion 24. The other end of the electric expansion and contraction mechanism 70 is connected to the front frame 33 of the seat frame 30 via an expansion and contraction mechanism connection portion 39. The electric expansion and contraction mechanism 70 can include an electric motor 71 and a ball screw. In this case, the rotation of the output shaft of the electric motor 71 is transmitted to the ball screw via a gear such as a worm gear, whereby the electric expansion and contraction mechanism 70 expands and contracts, and the space between the expansion and contraction

mechanism connection portions

24 and 39 It can be changed.

FIG. 4 shows a first state in which the electric expansion and contraction mechanism 70 is retracted and the backrest 12 is raised. When the reclining chair 10 is in the first state, a seated person sitting on the seating portion 11 can easily stand. In this first state, when the electric expansion and contraction mechanism 70 is extended, the entire seat frame 30 and the lower portion of the back frame 40 move forward with respect to the base frame 20, and the back frame 40 rotates with respect to the seat frame 30 As a result, the backrest 12 falls back. Thereby, the reclining chair 10 is in the second state shown in FIG.

When the reclining chair 10 is in the second state, a seated person sitting on the seating portion 11 can relax. In the second state, the seat frame 30 is disposed forward as compared to the first state, and the front end of the seat frame 30 is positioned above.

By arranging the first traveling part 52a horizontally, the second traveling part 52b extends upward as it goes forward. When the reclining chair 10 transitions from the first state to the second state, the rear traveling tool 32b provided at the rear end of the seat frame 30 travels the first traveling part 52a of the traveling surface 52, and the seat The front traveling tool 32 a provided at the front end of the frame 30 travels on the second traveling portion 52 b of the traveling surface 52. That is, while the rear side traveling tool 32b moves horizontally, the front side traveling tool 32a moves obliquely upward. Thus, as the seat frame 30 moves forward, in other words as the backrest 12 falls back, the angle of inclination of the seat frame 30 relative to the horizontal increases.

According to the present embodiment, the following effects can be achieved.

(1) With the reclining of the backrest 12, the seat frame 30 moves forward. The movement of the seat frame 30 is guided by the traveling tool 32 traveling on the traveling surface 52 of the rail member 50. The traveling surface 52 of the rail member 50 is bent. Therefore, it is possible to change the moving direction of the seat frame 30 only by the rail member 50, and it is possible to change the angle and position of the seat frame 30 with a simple structure as the backrest 12 reclines.

(2) The second traveling portion 52b extends upward as it goes forward. Therefore, the front end of the seat frame 30 is lifted even when the first travel portion 52a is disposed horizontally, or even when the first travel portion 52a is provided with a smaller inclination than the second travel portion 52b. Can be moved. That is, when the traveling tool 32 travels the second traveling portion 52b, the seat frame 30 moves forward while the front end of the seat frame 30 lifts along with the reclining of the backrest 12. As a result, the rear end of the seat frame 30 can be lowered to prevent the seat occupant from moving forward too much.

(3) The traveling tool 32 is a rotating body provided on the side frame 31 and rotating with respect to the side frame 31. This structure allows the seat frame 30 to move smoothly as compared with a configuration in which the traveling tool 32 slides while rubbing the traveling surface 52 of the rail member 50 without rotating.

(4) The traveling tool 32 is provided on the seat frame 30, and the rail member 50 is provided on the base frame 20. For this reason, the seat frame 30 can be made lightweight while fixing the rail member 50 firmly.

(5) Since the chair type massage machine 1 is provided with the reclining chair 10, the effect as described in said (1) can be acquired. As a result, it is possible to seat a seated person at a position suitable for massage with a simple structure.

Second Embodiment
A second embodiment of the present invention will be described with reference to FIGS. 6 to 8. In addition, about the structure similar to 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted or simplified. Further, in FIGS. 6 to 8, the illustration of the electric expansion and contraction mechanism 70 is omitted.

As shown in FIG. 6, the traveling surface 52 of the present embodiment includes a first traveling unit 52a, a second traveling unit 52b, and a third traveling unit 52c, each of which is linear. The third travel unit 52c is connected to the front end of the second travel unit 52b. The rail member 50 is formed to extend downward as the third travel portion 52c goes forward when the first travel portion 52a is disposed horizontally.

FIG. 6 shows a first state in which the electric expansion and contraction mechanism 70 is retracted and the backrest 12 is raised. FIG. 7 shows a second state in which the electric expansion and contraction mechanism 70 is extended and the backrest 12 is fallen.

When the reclining chair 10 transitions from the first state to the second state, the rear traveling tool 32b provided at the rear end of the seat frame 30 travels the first traveling part 52a of the traveling surface 52, and the seat The front traveling tool 32 a provided at the front end of the frame 30 travels on the second traveling portion 52 b of the traveling surface 52. Therefore, as in the first embodiment, when the first state is transitioned to the second state, the inclination angle of the seat frame 30 with respect to the horizontal direction increases.

Furthermore, in the present embodiment, the electric expansion and contraction mechanism 70 can be further extended in the second state. By this extension, the entire seat frame 30 and the lower portion of the back frame 40 move further forward. Then, the backrest 12 falls further rearward, and the inclination angle of the seat frame 30 with respect to the horizontal direction decreases.

FIG. 8 shows a third state in which the electric expansion and contraction mechanism 70 is further extended and the backrest 12 falls further rearward than the first state and the second state. When the reclining chair 10 is in the third state, a seated person sitting on the seating portion 11 can relax more. In the third state, as compared with the second state, the seat frame 30 is disposed forward and the front end of the seat frame 30 is positioned downward.

In the present embodiment, the first traveling part 52a is disposed horizontally, the second traveling part 52b extends upward as it goes forward, and the third traveling part 52c extends downward as it goes forward. When transitioning from the second state to the third state, the rear traveling tool 32b provided at the rear end of the seat frame 30 travels the first traveling portion 52a of the traveling surface 52, and the front side of the seat frame 30 The front traveling tool 32 a provided at the end travels on the third traveling portion 52 c of the traveling surface 52. That is, while the rear side travel tool 32b moves horizontally, the front side travel tool 32a moves obliquely downward. Therefore, as the backrest 12 falls further rearward from the second state, the inclination angle of the seat frame 30 with respect to the horizontal direction decreases.

According to the present embodiment, in addition to the effects described in (1) to (5) of the first embodiment, the following effects can be achieved.

(6) The third traveling portion 52c extends downward as it goes forward. Therefore, when the traveling tool 32 travels through the third traveling portion 52c, the angle formed between the backrest 12 and the seating portion 11 can be increased along with the reclining of the backrest 12. As a result, the seated person can sit on the reclining chair 10 in a more relaxed posture.

Third Embodiment
A third embodiment of the present invention will be described with reference to FIGS. 9 and 10. In addition, about the structure similar to the said 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted or simplified. Moreover, in FIG. 9 and FIG. 10, illustration of the electric expansion and contraction mechanism 70 is abbreviate | omitted.

As shown in FIG. 9, the traveling surface 52 of the present embodiment includes a first traveling unit 52a and a second traveling unit 52b each of which is linear. The first travel unit 52a is connected to the rear end of the second travel unit 52b. When the second travel portion 52b is disposed horizontally, the rail member 50 is formed such that the first travel portion 52a extends upward as it goes rearward.

Further, in the present embodiment, the rear side travel tool 32b is supported at substantially the same height as the side frame 31, while the front side travel tool 32a is suspended from the side frame 31 and supported downward. . That is, when the side frames 31 are arranged horizontally, height differences occur in the plurality of traveling tools 32 in the vertical direction.

FIG. 9 shows a first state in which the electric expansion and contraction mechanism 70 is retracted and the backrest 12 is raised. FIG. 10 shows a second state in which the electric expansion and contraction mechanism 70 is extended and the backrest 12 is fallen. In the second state, the seat frame 30 is disposed forward as compared with the first state, and the rear end of the seat frame 30 is positioned downward.

In the present embodiment, the second traveling part 52b is disposed horizontally, and the first traveling part 52a extends downward as it goes forward. Therefore, while the front side travel tool 32a moves horizontally, the rear side travel tool 32b moves obliquely downward. Thus, as the seat frame 30 moves, in other words as the backrest 12 falls, the angle of inclination of the seat frame 30 relative to the horizontal increases.

According to the present embodiment, in addition to the effects described in (1) and (3) to (5) of the first embodiment, the following effects can be achieved.

(7) The first traveling portion 52a extends downward as it goes forward. The distance from the front traveling tool 32 a to the side frame 31 is larger than the distance from the rear traveling tool 32 b to the side frame 31. Therefore, the rear end portion of the seat frame 30 can be lowered by the rear traveling tool 32b traveling on the second traveling portion 52b. Therefore, it is possible to prevent the seated person from moving forward too much. In addition, since the change in height of the front end of the seat frame 30 is small, even in the second state, a seated person sitting on the seating portion 11 can easily stand.
