Description

[0002] Elevators for wheel chairs in which a boarding section can be rotated.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifting device for a wheelchair in which a boarding section is rotatable, and more particularly to a lifting device for a wheelchair in which a boarding section is rotatable so that a boarding section on which a wheelchair is mounted can be rotated, .

As the quality of life improves with the development of modern society, the interest of people with disabilities is increasing day by day. There is substantial investment in environment improvement for people with disabilities. Especially, in some countries, Wheelchair lifts are required to be installed in facilities and commercial areas.

Generally, a wheelchair is a means of transportation used by persons with disabilities and patients who are inconvenienced by physical disabilities and uncomfortable behaviors. Those who are uncomfortable in walking are satisfied with their functions as a means of transportation but actually use other activities such as a train, a car or a staircase The inconvenience of moving occurred due to the difference in height of boarding or moving.

Therefore, the present applicant has found that, even when the landing gear for a wheelchair is not positioned accurately at the gate of a vehicle through the "elevator for wheelchair ", Korean Patent Registration No. 10-1372262 discloses that the landing gear is accurately positioned And a ball bearing is disposed in a circular guide groove so that the ball bearing moves along the guide groove to finally rotate the boarding portion. The guide groove is formed with a stop groove at a predetermined interval, And the rotational position of the boarding portion is determined.

However, since the above-mentioned positioning is determined by the number of the stop grooves installed, if the stop grooves are installed a lot, the structure becomes weak. When the stop grooves are installed in a small amount, the rotation angle is large.
