BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a displacement mechanism, and more particularly to the displacement mechanism which is capable of moving a disabled person to getting into and out of a car.

Description of the Prior Art

There are many tools (such as a wheelchair) to assist a patient and a disabled person to move, but it is difficult to move the patient and the disabled person to get into and out of the car. To solve such a problem, a caregiver (such as a female caregiver) has to move the patient and the disabled person physically. Furthermore, the disabled person will be hurt during being moved.

To improve such a defect, a conventional displacement mechanism has been developed, but it is complicated, produced at a high cost, sold at a high price, and is operated arduously.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide a displacement mechanism which is simplified, produced at a low cost, sold at a low price, and used flexibly.

Another object of the present invention is to provide a displacement mechanism which is capable of moving the disabled person upward and downward easily and quickly.

To obtain above-mentioned aspect, a displacement mechanism provided by the present invention contains: a support rack, a sitting assembly, a slide rod, two fixing feet, a back, a first holding plate, a second holding plate, and an expandable sheet.

The support rack includes a fixer formed on a top of the support rack, a rolling stand connected on a bottom of the support rack. The rolling stand has multiple first rollers mounted on a bottom of the rolling stand, and the support rack further includes a lifter defined between the fixer and the rolling stand. The fixer has a post extending upward from a side thereof.

The sitting assembly is slidably mounted on the fixer of the support rack, the sitting assembly includes a receiving orifice defined on one of two side surfaces of the sitting assembly, and the sitting assembly includes a rotatable mounting rotatably connected on a front end of the sitting assembly.

The slide rod includes an elongated hole defined on the slide rod and configured to connect the slide rod with the post of support rack, such that the slide rod slides with respect to the post and is slidably received in the receiving orifice of the sitting assembly.

The two fixing feet is mounted on two bottoms of two side surfaces of the rotatable mounting, and a respective foot includes a second roller connected on a bottom of the respective foot.

The back is disposed on a rear end of the sitting assembly.

The first holding plate is mounted on a seat of a wheelchair, and the sitting assembly is slid between the fixer of the support rack and the first holding plate.

The second holding plate is connected on a seat of a car.

The expandable sheet is disposed between the fixer of the support rack and the second holding plate so that the sitting assembly slides between the fixer of the support rack and the second holding plate.
