It has horizontal bars 12 and 13 connected to left and right side frames 11. The left and right side frames 11 are provided in a symmetrical manner, each having four connecting rods 41, 42, 43, 44 and one telescopic tube mechanism 45. A lower part of the two armrests 30 is a support rod 31, and a rod 32 is connected to a lower end of the support rod 31. The seat mounting seats 20 are fixed on the fourth connecting rods 44 of the left and right side frames 11. One end of the first, second, third and fourth connecting rods 41, 42, 43 of the side frame 11 is pivotally connected to the standing rod 14 at the rear end of the side frame 11, and the first and third connecting rods 41, 43 are connected. The other end is pivotally connected to the fourth connecting rod 44. The upper end of the rod 32 at the lower end of the armrest 30 is pivotally connected to the middle portion of the first connecting rod 41. The end of the main body 451 of the telescopic tube mechanism 45 is pivotally connected to the first connecting rod 41, and the outer end of the telescopic tube 452 is pivotally connected to the bottom rod 15 at the bottom of the side frame 11. That is, the first and second connecting rods 41 and 42 and the rod 32 at the lower end of the armrest 30 form a kind of three connecting rod mechanism. The first, third and fourth connecting rods 41, 43 and 44 form a kind of three connecting rod mechanism. When the telescopic tube 452 of the telescopic tube mechanism 45 extends, the first connecting rod 41 is directly driven and raised, and the second, third and fourth connecting rods 42, 43, 44 and the rod 32 are thereby raised. Then, the seat mounting seat 20 and the armrest 30 are driven up by this, and lift the user's body as shown in FIG.

In the three connecting rod mechanism formed by the first and second connecting rods 41 and 42 and the rod body 32 at the lower end of the armrest 30, one end of the first and second connecting rods 41 and 42 is connected to the side frame 11. It is pivotally connected to the rod 14 and forms two pivot contacts 51,52. The upper and lower ends of the rod 32 are pivotally connected to the other ends of the first and second connecting rods 41 and 42 to form two other pivotal contacts 53 and 54. The four pivot points 51, 52, 53, 54 form four vertices of a parallel square, i.e. during the ascent of the first and second connecting rods 41, 42 and the rod 32, these four pivot points 51, 52, 53, 54 52, 53 and 54 are vertices of a parallel rectangle forever. Therefore, the armrest 30 maintains a horizontal state during the process of ascending or descending, providing a safe and stable support for the user.

The lower end of the above-described fourth connecting rod 44 is pivotally connected to the third connecting rod 43, the middle portion thereof is pivotally connected to the first connecting rod 41, and the upper end thereof is extended inward to form the frame body 21. The upper part of the frame body 21 is fixed to a seat mounting seat 20 having a hole in the center. The distance between the pivot contacts 55 and 56 at both ends of the third connecting rod 43 is larger than the distance between the pivot contacts 51 and 57 at both ends of the first connecting rod 41. An action of tilting forward is generated, whereby the seat mounting seat 20 generates an inclining action, causing the user to form an almost upright state after standing up, as shown in FIG.

The telescopic tube mechanisms 45 and 46 of the two side frames 11 operate synchronously, move up and down synchronously with the armrests 30 on the left and right side frames 11, and move up and down on the seat mounting seat 20. The descending operation is performed.

The above-mentioned telescopic tube mechanism 45 is a well-known mechanism. As shown in FIG. 4, it is a motor 453, a guide screw rod 454 driven by the motor 453, and a telescopic screw screwed with the guide screw rod 454. A tube 452 is provided. When the motor 453 drives and rotates the guide screw rod 454, whether the telescopic tube 452 expands or contracts depends on the rotation direction of the guide screw rod 454.

The center of the first, second, and third connecting rods 41, 42, and 43 is formed in a penetrating shape, and the central hollow portion of the first connecting rod 41 is used for penetrating the supporting rod 31 of the armrest 30. The hollow portions of the second and third connecting rods 42 and 43 are used for penetration of the telescopic tube mechanism 45.

A push button 60 for operating the operation of the two telescopic tube mechanisms 45 is provided at the front end of the armrest 30, as shown in FIG. 1, so that the user can select the selection buttons 61, 62. It is convenient. As shown in FIG. 5, a screw 64 penetrates a substrate 63 inside the push button 60, and an elastic piece 65 having an opening facing outward is screwed into an inner end of the screw nail 64. When outwardly projecting, the four corners of the elastic piece 65 press against the inner wall of the tube of the armrest 30 (in the above embodiment, the diameter of the tube of the armrest is an arc shape). The substrate 63 is fixed. The case 66 of the push button 60 is connected to the substrate 63 by a fitting method. Therefore, after the push button 60 is attached, the screw component is not visible in appearance.

A case (not shown) can be installed on the two side frames 11 of the present invention, and covers the entire connecting rod mechanism. As a result, the appearance of the fuselage is further improved, and it is possible to prevent improper substances from entering the entire mechanism.

When an elderly or sick person wants to sit down and take a toilet, the seat mounting seat 20 which has already been raised is first lowered, and then the seat mounting seat 20 and the armrest 30 are lowered, whereby most of the weight of the user's body is reduced. When a user who can be supported by the mounting seat 20 wants to stand up, the seat mounting seat 20 and the armrest 30 are raised. Therefore, when the elderly and the sick are sitting on the toilet, the thighs do not need to support the entire weight of the body, and no one can take care of the toilet, and the toilet can be completed alone.

Of the two armrests 30 described above, the support bar 31 ′ of one armrest 30 can be selected to provide a two-stage design. As shown in FIG. 6, the upper stage 33 and the lower stage 34 of the support rod 31 'are pivotally connected by a shaft 35, and a locking groove 36 is provided near the lower end of the upper stage 33. 37 is provided, and the stopper pin 37 of the lower stage 34 is engaged with the locking groove 36 of the upper stage 33, whereby the upper stage 33 and the lower stage 34 are connected. When the upper stage 33 is bent backward and downward, the locking groove 36 of the upper stage 33 is separated from the stopper pin 37 of the lower stage 34, and the armrest 30 is rotated backward as shown in FIG. This is convenient for the user to enter from the side of the machine. The stopper pin 37 penetrates through the elongated hole 38 and can move up and down slightly, and the tension spring 39 separately acts to suppress the stopper pin 37 downward. When the locking groove 36 of the upper stage 33 engages with the stopper pin 37, an action of hooking the stopper pin 37 upward is generated, and a good positioning force and a good feeling of engagement are generated.
