## Abstract

A structure including left and right footplates and weight shafts provided at left and right sides in a blood circulation exercise interlocking device, providing a pelvic limb blood circulation ankle interlocking device comprising a vertical supporter configured at the center of a lower plate of a main body in a vertical direction, left and right auxiliary vertical supporters configured to be parallel in a vertical direction at left and right sides of the vertical supporter, rotary shafts configured at the same position as the left and right auxiliary vertical supporters in a horizontal direction of the vertical supporter, left and right rotary bars configured at left and right sides of the rotary shaft to be coupled with a rotating device, weights made of heavy metals at the upper ends of the left and right rotary bars, and left and right footplates configured at left and right rotation lower ends.

## Claims

### Claim 1

A device for pelvic limb blood flow comprising:
a vertical supporter extending vertically from a lower plate of a main body in a vertical direction;
a rotary shaft configured in a form of a bar at a predetermined height on the vertical supporter and extending horizontally from the vertical supporter in;
left and right rotary bars each having an upper end and a lower end that are configured to rotate up and downward, respectively, around the rotary shaft;
first and second weights provided at the upper ends of the left and right rotary bars, respectively; and
left and right footplates provided at the lower ends of the left and right rotary bars, respectively,
wherein when a user sequentially presses on the left and right footplates, the first and second weights sequentially rotate upward by a rotation of the left and right rotary bars around the rotary shaft, respectively, and when the user releases pressure off the left and right footplates, the first and second weights rotate downward by gravity to return the left and right footplates back to an initial position.

### Claim 2 (depends on 1)

The device for pelvic limb blood flow of claim 1, wherein the device is used with a chair structure.

### Claim 3 (depends on 1)

The device for pelvic limb blood flow of claim 1, wherein the device is used with a desk structure.

### Claim 4 (depends on 1)

The device for pelvic limb blood flow of claim 1, wherein the device is used with one side of a bed structure.

### Claim 5 (depends on 1)

The device for pelvic limb blood flow of claim 1, further comprising a stop shaft configured on the vertical supporter to stop the left and right rotary bars from rotating past the stop shaft.
