The lower rotation fulcrum member 42 is rotatably provided to the leg moving frame 3 about a second rotation axis P2, and the second rotation axis P2 is provided vertically below the first rotation axis P1.

Please refer to fig. 2a and fig. 2 b. The reciprocating part 5 has a left elevating part 51, a right elevating part 52, an upper connecting part 53 and a lower connecting part 54.

Both ends of the upper connecting portion 53 are connected to the upper end of the left elevating moving portion 51 and the upper end of the right elevating moving portion 52, respectively. The upper connecting portion 53 is linked by contacting with the upper rotation fulcrum 41, for example: the friction force between the two or the concave-convex matching mode is adopted.

Both ends of the lower connecting portion 54 are connected to the lower end of the left elevating moving portion 51 and the lower end of the right elevating moving portion 52, respectively. The lower connecting portion 54 is linked to the lower rotation fulcrum member 42 by contact, for example: the friction force between the two or the concave-convex matching mode is used.

In some embodiments, the upper rotation fulcrum member 41 and the lower rotation fulcrum member 42 may be pulleys, gears, or pulleys. The reciprocating part 5 may be a rope, a chain or a belt.

When the reciprocating portion 5 is a rope or a belt, the upper rotation fulcrum member 41 and the lower rotation fulcrum member 42 may be pulleys or pulleys that are correspondingly engaged with each other, the rope or the belt rotates the upper rotation fulcrum member 41 and the lower rotation fulcrum member 42 clockwise or counterclockwise by a friction force, and the rope or the belt itself moves around the upper rotation fulcrum member 41 and the lower rotation fulcrum member 42. When the reciprocating portion 5 is a chain, the upper rotating fulcrum member 41 and the lower rotating fulcrum member 42 may be gears correspondingly engaged with the chain, and the chain and the gears are in concave-convex engagement, so that the chain can drive the upper rotating fulcrum member 41 and the lower rotating fulcrum member 42 to rotate clockwise or counterclockwise, and the chain itself moves around the upper rotating fulcrum member 41 and the lower rotating fulcrum member 42. In these embodiments, the rope, chain or belt surrounds a portion of the upper and lower

rotation fulcrum members

41 and 42, and different sections of the rope, chain or belt serve as the left and right

elevation movement portions

51 and 52, the upper connection portion 53 and the lower connection portion 54, respectively. The left lifting part 51 and the right lifting part 52 move in opposite directions.

The left elevating member 61 is disposed at the left elevating moving part 51. The left lifter 61 has a left leg placing portion 611 for the exerciser to place the left lower leg.

The right lifting member 62 is disposed on the right lifting moving portion 52, and the right lifting member 62 has a right leg placing portion 621 for the player to place the right lower leg. Preferably, the left lifter 61 and the right lifter 62 are detachably disposed to satisfy convenience of transportation and storage. Preferably, the leg moving frame 3 is rotatably disposed on the seat body 1, and the leg moving frame 3 is provided with a knob 31 for adjusting the tilting angle of the leg moving frame 3.

Preferably, the left lifting and lowering part 51 and the right lifting and lowering part 52 keep moving vertically, so that the left lifting and lowering part 61 and the right lifting and lowering part 62 can lift and lower vertically with respect to the ground, so that the legs of the sporter only change the lifting positions during the movement, and the opening and closing angles of the legs are not changed. In one embodiment, the upper rotation fulcrum member 41 and the lower rotation fulcrum member 42 use pulleys, gears or pulleys of the same specification, and the reciprocating part 5 uses a corresponding rope, chain or belt.

As shown in fig. 3, the exerciser applies different forces to the left leg placement portion 611 and the right leg placement portion 621 through the left lower leg and the right lower leg, and the left lifting member 61 and the right lifting member 62 drive the left lifting portion 51, the right lifting portion 52, the upper connection portion 53, the lower connection portion 54, the upper rotation fulcrum member 41 and the lower rotation fulcrum member 42 to move, so that the left lifting member 61 and the right lifting member 62 move up or down (as shown in fig. 2a and 2 b), thereby achieving the purpose of moving the legs.

In this embodiment, the seat body 1 is further provided with a resistance mechanism, and the resistance mechanism is connected with a pedal plate for the user to exercise the legs. The resistance mechanism may be a flywheel device 7a, which the exerciser steps on by the foot pedal 71a to achieve a bicycle-like exercise effect.

Referring to fig. 5 and 6, in another embodiment, the resistance mechanism is a thigh push-pedal machine 7b, and the exerciser exercises thigh muscles by pushing the pedal 71b with both feet. Alternatively, as shown in fig. 7, in one embodiment, the pedal 71b has two protruding placing parts 711b and a connecting part 712 b. The two placement portions 711b are provided on the left and right, and the connecting portion 712b connects the two placement portions 711 b. In the leg rehabilitation exercise device 100 of the present invention, the flywheel device 7a and the thigh push-pedal device 7b may be set simultaneously or alternatively.

In this embodiment, the leg-rehabilitation exercise apparatus 100 further includes a pulling member 8. The pulling force assembly 8 includes an elastic element 81 and a handle 82, one end of the elastic element 81 is connected to the seat 2 or the seat 1, and the other end of the elastic element 81 is connected to the handle 82. The resilient member 81 may be a spring. As shown in FIG. 3, the user can lift the handle 82 in a dumbbell-like manner to exercise the muscles of the hand.

In another embodiment, as shown in fig. 4, the pulling member 8a can also be disposed at a higher position on the seat portion 2, and the exerciser can pull the elastic member 81a by pulling down the grip 82a to exercise the hand muscles.

Alternatively, as shown in fig. 1a and 1b, a rotary sub-handle 821 may be connected to the handle 82. The rotary sub-grip 821 is provided so as to be rotatable toward the inside of the seat 2. The rotating sub-handle 821 can be rotated to the front-rear direction when the pulling force assembly 8 is not used or after use, so as to facilitate the sportsman to sit on or leave the seat portion 2. When it is desired to use the pulling force assembly 8, the rotating sub-handle 821 can be rotated inwardly to facilitate the exerciser to apply force to use the pulling force assembly 8.

Preferably, in one embodiment, the leg exercise frame 3 is provided with a counting device 9 for sensing and counting the number of times the left and

right lifters

61 and 62 move past the counting device 9, and the exerciser can know the number of times his/her leg exercise from the counting device 9.
