Fig. 2 is a view of the medical chair as viewed from the direction of arrow II in fig. 1.
In fig. 2, the headrest 2d shown in fig. 1 is not shown. Fig. 2 shows a state where the back plate 2c stands up.
In the present embodiment, a lifting mechanism 2a for lifting and lowering the seat surface 2g is provided below the seat surface 2 g. The lifting mechanism 2a includes a motor (described later), and drives the motor to lift and lower the seat surface 2 g.
Fig. 3 is a diagram showing an internal configuration of a portion denoted by symbol III in fig. 2. Fig. 4 is a view of a part of the lifting mechanism 2a as viewed from the direction of arrow IV in fig. 3 (from the back side and the top of the paper surface in fig. 3).
As shown in fig. 3, the lifting mechanism 2a of the present embodiment is provided with a support portion (support member) 40 that supports the seat surface 2g from below.
Note that the supporting means for the seat face 2g (see fig. 2) of the support portion 40 is not limited to the means in which the support portion 40 directly supports the seat face 2g, and includes means in which another member is interposed between the support portion 40 and the seat face 2g, and the support portion 40 supports the seat face 2g by the other member.
In the support portion 40 shown in fig. 3, the cross-sectional shape on the plane orthogonal to the longitudinal direction of the support portion 40 is U-shaped. The support portion 40 extends obliquely downward from the upper side on which the seat surface 2g is provided.
In the present embodiment, the first rotation shaft 61 is provided below the seat surface 2g and extends in the lateral direction (horizontal direction). The support portion 40 rotates about the first rotation shaft 61.
In the present embodiment, a plate-shaped base 71 disposed along the floor surface, and a first support frame 721 and a second support frame 722 extending upward from the base 71 and disposed to face each other are provided.
In the present embodiment, the end portions of the first rotating shaft 61 are supported by the first support frame 721 and the second support frame 722.
In the present embodiment, a motor M is provided as an example of a drive source. In the present embodiment, the seating surface 2g is raised and lowered by the motor M.
In the present embodiment, a driving force receiving portion 73 is provided to receive a driving force (driving force from the motor M) for raising and lowering the seat surface 2 g.
A transmission portion 74 is provided to transmit the driving force from the motor M to the driving force receiving portion 73.
The driving force receiving portion 73 is provided to be movable about the first rotation shaft 61. The driving force receiving portion 73 raises the seat surface 2g by rotating the support portion 40 about the first rotation shaft 61.
In the present embodiment, a projecting portion 75 is provided which is fitted to the support portion 40 and projects downward. In the present embodiment, a driving force receiving portion 73 is provided at the tip end portion of the projecting portion 75 in the projecting direction.
The driving force receiving portion 73 is formed of a cylindrical member having a female screw formed on an inner peripheral surface thereof, and the driving force receiving portion 73 receives the driving force from the transmission portion 74 at a portion of the female screw.
In the present embodiment, the driving force receiving portion 73 is rotatable about a rotation axis 73A (see fig. 5) along a direction orthogonal to the axial direction of the cylindrical driving force receiving portion 73. Incidentally, the driving force receiving portion 73 is rotatable relative to the projecting portion 75.
Thus, in the present embodiment, even if the inclination of the transmission portion 74 is increased (described later), the transmission portion 74 and the driving force receiving portion 73 are kept coaxially arranged.
The transmission portion 74 shown in fig. 3 is formed of a cylindrical shaft having a helical male screw formed on an outer peripheral surface thereof.
In fig. 3, a second rotation shaft 62 (hereinafter referred to as "transmission portion rotation center 62X") extending in the lateral direction (horizontal direction) is provided at the right end portion of the transmission portion 74 in the drawing, and in the present embodiment, the transmission portion 74 rotates about the transmission portion rotation center 62X.
In the present embodiment, a rotary member 761 is provided so as to be rotatable about the third rotation shaft 63 and the fourth rotation shaft 64 (not shown in fig. 3). In the rotary member 761, a cross-section in a plane perpendicular to the longitudinal direction of the rotary member 761 has a U-shape.
As shown in fig. 4, the rotating member 761 includes a first projection 761A and a second projection 761B at the end portion on the side of the transmission portion 74.
The first projection 761A is disposed between the first support frame 721 and one of the projections 75. The second projection 761B is disposed between the second support frame 722 and the other projection 75.
In the present embodiment, the first projection 761A is rotatably supported by the third rotation shaft 63 (see fig. 3), and the second projection 761B is rotatably supported by the fourth rotation shaft 64 (the rotation shaft disposed coaxially with the third rotation shaft 63 (see fig. 3)).
As shown in fig. 3, the rotation member 761 is disposed below the support portion 40. The rotating member 761 is arranged in parallel with the support portion 40.
As shown in fig. 3, in the present embodiment, a fixing member 77 is fixed to the left end portion of the support portion 40 and the rotating member 761 in the figure. In the present embodiment, a seat surface 2g (see fig. 2) is provided above the fixing member 77.
The fixing member 77 is fixed to the support portion 40 and the rotating member 761 by the fifth rotating shaft 65 and the sixth rotating shaft 66.
Thus, in the present embodiment, the posture of the fixing member 77 relative to the support portion 40 and the rotating member 761 can be changed.
In the present embodiment, the transmission portion 74 is rotated in the circumferential direction by the motor M shown in fig. 3, and the driving force receiving portion 73 is moved in the direction indicated by the arrow 3A in the figure.
When the driving force receiving portion 73 moves in the direction indicated by the arrow 3A, the support portion 40 rotates in the direction indicated by the arrow 3B in the figure about the first rotation shaft 61. When the support portion 40 is rotated in the direction indicated by the arrow 3B, the fixing member 77 is raised, and the seat surface 2g is raised accordingly.
In the present embodiment, even when the support portion 40 rotates, the support portion 40 and the rotating member 761 are kept parallel to each other.
Thus, in the present embodiment, the fixing member 77 is raised while maintaining the posture with respect to the floor surface, and in this case, the seat surface 2g is raised while maintaining the horizontal state.
When the seating surface 2g is lowered, the motor M is reversed.
Fig. 5 is a diagram showing the lifting mechanism 2a after the seat face 2g is lifted.
When the seat surface 2g is raised, in the present embodiment, a part (left end portion in the drawing) of the transmission portion 74 is pulled upward by the raised driving force receiving portion 73.
Thus, in the present embodiment, as shown in fig. 5, the inclination of the transmission portion 74 with respect to the ground surface is increased.
Incidentally, in the present embodiment, in a state before the seat surface 2g is raised (in a lowered state in which the seat surface 2g is lowered to the lowest level), as shown in fig. 3 and 4, the transmission portion 74 is along the horizontal direction (along the ground surface).
When the seating surface 2g rises, the inclination of the transmission portion 74 with respect to the ground surface becomes larger, and the transmission portion 74 is inclined with respect to the ground surface.
Here, in order to incline the transmission unit 74 as described above, for example, a dedicated drive source for inclining the transmission unit 74 may be prepared, and a part of the transmission unit 74 may be raised by the drive source. However, this solution leads to an increase in cost or an increase in size of the apparatus.
In contrast, in the configuration in which the transmission portion 74 is inclined by the driving force receiving portion 73 lifting up a part of the transmission portion 74 as in the present embodiment, there is no need to prepare a dedicated driving source, and cost reduction and device miniaturization can be achieved.
Further, as in the present embodiment, when the transmission portion 74 is disposed in a state along the horizontal direction in the lowered state in which the seating surface 2g is lowered to the lowest, the size of the portion indicated by reference numeral 2H in fig. 2 can be reduced as compared with the case where the transmission portion 74 is inclined.
In the case where the size of the portion indicated by reference numeral 2H can be reduced, the foot support portion 402e can be located closer to the lower side, and in this case, the patient can more easily sit on the medical chair 2.
In the present embodiment, as shown in fig. 5, the rotation angle β of the transmission portion 74 having the transmission portion rotation center 62X as the rotation center is smaller than the rotation angle α of the driving force receiving portion 73 having the first rotation shaft 61 as the rotation center.
Incidentally, the rotation angle of the driving force receiving portion 73 around the first rotation shaft 61, in which the seating surface 2g is lowered to the lowest state and is raised to the highest state, is defined as the rotation angle α.
The rotation angle of the transmission 74 from the lowered state to the raised state with the transmission rotation center 62X as the rotation center is defined as a rotation angle β.
In this case, in the present embodiment, the rotation angle β of the transmission portion 74 is smaller than the rotation angle α of the driving force receiving portion 73.
As described above, when the rotation angle β of the transmission portion 74 is small, the size of the portion indicated by reference numeral 2H in fig. 2 can be reduced as described above. In this case, as described above, the foot support portion 402e can be located closer to the lower side, and the patient can more easily sit on the medical chair 2.
In the present embodiment, as shown in fig. 5, the motor M is attached to the transmission portion 74, and even if the inclination of the transmission portion 74 changes, the posture of the transmission portion 74 changes, and the posture of the motor M with respect to the transmission portion 74 is kept constant in the present embodiment.
Here, for example, if the motor M is fixed to the ground, the transmission unit 74 moves relative to the motor M, and the transmission mechanism for transmitting the driving force from the motor M to the transmission unit 74 is likely to be complicated.
In contrast, as in the present embodiment, the motor M is mounted on the transmission portion 74, and a gear having a fixed structure, for example, can be provided between the motor M and the transmission portion 74, thereby simplifying the structure.
In the configuration of the present embodiment (in the configuration in which the inclination of the transmission portion 74 is increased), the seating surface 2g can be raised more efficiently.
Here, as a comparative example shown in (a) and (B) of fig. 6 (a diagram showing a comparative example of the elevating mechanism 2 a), a configuration in which the inclination of the transmission portion 74 is not increased can be considered as a configuration of the elevating mechanism 2 a.
In this comparative example, the transmission portion 74 is always arranged along the horizontal direction, and the driving force receiving portion 73 is movable relative to the projecting portion 75. More specifically, in this comparative example, a groove 99 is formed in the projecting portion 75, and the driving force receiving portion 73 is movable along this groove 99.
In this comparative example, as shown in fig. 6B, when the seat surface 2g (not shown in fig. 6B) rises, the angle θ between the transmission portion 74 and the projecting portion 75 becomes small, and a load acting in the direction shown in fig. 6A (the direction orthogonal to the projecting direction of the projecting portion 75) is less likely to act on the projecting portion 75. Incidentally, in this comparative example, the force is difficult to be transmitted from the transmitting portion 74 to the projecting portion 75.
In contrast, in the configuration in which the inclination of the transmission portion 74 is increased as in the present embodiment, the load acting on the projecting portion 75 is increased in the direction orthogonal to the projecting direction of the projecting portion 75 as compared with the comparative example shown in fig. 6.
In this case, the force is easily transmitted from the transmission portion 74 to the protrusion portion 75, and the seating surface 2g is easily raised. Incidentally, in this case, the seat surface 2g can be raised with less force.
