Further, in the unlocked state, the backrest portion 5 performs the reclining operation by the action of the parallel link mechanism 21.

A footrest 45 is provided in front of the base portion 13. The footrest 45 is supported by the base portion 13 via a footrest link mechanism 47. The footrest mechanism 47 is composed of a plurality of link members, and is provided as a left and right pair. The left and right footrest mechanisms 47 are connected to each other by a rod, and an extension / contraction operation is performed by a footrest electric cylinder 49 that is pin-connected to the substantially center of the rod. At this time, when the footrest link mechanism 47 is extended, the positional relationship of the link member at the tip is changed, and the footrest 45 is rotated by 90 degrees to be in a posture to receive the foot of the seated person.

(Operation) Hereinafter, the operation of this embodiment will be described focusing on the forward tilting and raising operation.

First, in a normal state (FIGS. 1 to 3),
The electric cylinder 19 is in a contracted state.

When the electric cylinder 19 extends from this state, the front link member 35 constituting the parallel link mechanism 21 tends to rotate forward around the lower pin coupling portion. At this time, if the backrest 5 is tilted rearward and reclined (that is, the hook 41 is also unlocked), an anti-reclining operation is performed and the backrest 5 is rotated forward and returned to the normal state. Be done.

When the electric cylinder 19 further extends, the rotation of the front link member 35 is restricted by the stopper 39.
Due to this regulation, the front link member 35 and the upper link member 27 that constitutes the four-bar linkage 17 are in a state of being integrated, and the movement of the electric cylinder 19 causes the front link member 35 of the parallel link mechanism 21 to rotate. It is not used for movement, but is converted into movement for deforming and raising the four-bar linkage 17. When the four-joint link mechanism 17 rises, the upper link member 27 forming the four-joint link mechanism 17 rises and tilts forward. As a result, the parallel link mechanism 21 as if integrated with the upper link member 27 also rises and tilts forward. Therefore, the movable portion 11 fixed to the upper link member 31 forming the parallel link mechanism 21 also rises and tilts forward. The angle of inclination before this is, for example, 35 degrees (FIG. 4).

Therefore, the seat portion 3, the backrest portion 5, and the armrest portion 7 provided on the movable portion 11 are entirely lifted and inclined forward. Due to this forward tilting movement, even a person who has a difficulty in standing or squatting by himself or herself can easily sit down or stand up from a seated state.

On the contrary, when the electric cylinder 19 contracts, the movable part 11, that is, the seat part 3, the backrest part 5, and the armrest part 7 return to the original state in the reverse order of the above-described operation.

When the electric cylinder 19 is further contracted, the front link member 35 constituting the parallel link mechanism 21 is stopped by the stopper 39.
Away from and pivots backward around the lower pin joint. If the hook 41 is disengaged at this time due to the rearward rotation, the parallel link mechanism 21 operates and the backrest portion 5 performs a reclining operation inclining rearward. If the hook 41 is locked, the reclining operation is not performed and the load acting on the electric cylinder 19 becomes large. Therefore, when this load is detected, the switch of the electric cylinder 19 is automatically turned off and the operation is stopped. To be done. The normal inclination angle of the backrest portion 5 is 25 degrees, but the inclination angle in the reclining state is 40 degrees.

With the backrest 5 reclining, the back of the seated person is positioned on the massage machine 9 built in the backrest 5. Therefore, the back of the seated person is pressed against the massaging machine 9 by the weight of the seated person, and more effective medical treatment is performed. Also, even if the seated person has difficulty keeping the spine vertical,
It is possible to easily spend time between medical treatments.

Further, another footrest electric cylinder 49
When the footrest 45 is extended, the footrest link mechanism 47 is extended, the footrest 45 is pushed away from the base portion 13 and rotated forward by 90 degrees to face upward. This makes it possible to hold the seated person's feet in a more horizontal direction. Therefore, the seated person can spend the time between the treatments more easily. Further, if another massaging machine or the like is built in the footrest 45, the weight of the foot of the seated person will press the foot against this massaging machine, which enables more effective medical treatment.

(Other Embodiments) In the above embodiment, the tip of the electric cylinder 19 is coupled to the pin coupling portion on the front link member 35 constituting the parallel link mechanism 21 via a rod (not shown). However, in another embodiment, the lower link member 29 constituting the parallel link mechanism 21 may be pin-coupled to the pin coupling portion on the right side in FIG. 2.

Further, in the above embodiment, the electric cylinder 19 is made to perform the forward tilting raising operation of the movable portion 11 by the extending operation, but in other embodiments, the electric cylinder 19 is contracted to perform the forward tilting raising operation. It is also possible to make it take place. That is, the posture of the electric cylinder 19 is set to 18 in the figure.
It is also possible to reverse the direction to 0 degree and to pin the rear end of the electric cylinder 19 not to the lower right in FIG. 2 but to the upper left in FIG.

In addition, in the above embodiment, kneading,
It has been described that the treatment such as tapping is performed by the massage machine 9 built in the backrest portion 5, but in other embodiments, the massage treatment is performed by the massage machine provided in a portion other than the backrest portion 5, or the massage is performed. The medical treatment may be performed by a device that gives an electrical stimulus other than the machine.
