Description

Vehicle shifting aid

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a shifting aid, and more particularly to a shifting method that utilizes a rail under the chair to move the extension panel to the left or right by means of a slide rail.

The shifting aid of the prior art has a shifting plate body, and the outer side of the main body is covered with a shifting cloth, and is slid on the shifting plate by using a drag shifting cloth, for example, the Republic of China Patent Gazette announced on December 11, 2013. A typical shifting device disclosed in No. M467452 comprises a shifting plate and a shifting cloth which is carried by the user on the shifting cloth and is assisted by the auxiliary person by dragging from the shifting plate. The shifting cloth moves from one end of the shifting plate to one end.

It is known that the shifting device is limited to a few functions. For example, a device must drag the shifting cloth when shifting, so that the user's body is shaken unbalanced, and the shift between the vehicle and the wheelchair cannot be used. The device of the known technology cannot fix the user's body, and is too dangerous in the process of displacement. Finally, after the displacement is completed to the designated area, the displacement plate is large in size and difficult to store, so it is necessary to develop a fixed user. The utility model can be used for shifting between the vehicle and the wheelchair, and does not move to the user body at all, and can be conveniently stored and carried.

The vehicular shifting device of the present invention includes an extension plate that is slidably mounted on the bottom of a chair. Before moving, pull the extension board out from the bottom of the chair, and wrap it with the devil's felt on both sides of the extension board and the steel tube on the side of the wheelchair seat to stabilize the extension board. Then the assistant can tow the sides of the seat. The handle is moved from the original position of the user to the wheelchair. After the movement is completed, the extension plate can be retracted from the bottom of the chair by the slide rail. Otherwise, the movement mode from the wheelchair to the interior seat and the extension plate storage method are the same. .

The invention can move without any movement to the user's body, and the displacement device is well stored and carried.

According to the present invention, the optimal shifting device comprises a seat surface 1, a reclinable seat back 4, a chair base 2 designed with a slide rail, and an extension panel 3 slidably hidden in the manner of a slide rail. The bottom surface of the chair base 2. The seat surface 1 has at least one plane on which the user's buttocks can ride, and can be accommodated on the seat surface of a wheelchair. Please refer to the second figure, the third figure, and the fourth figure. The chair base 2 and the extension plate 3 are combined and slidably combined through the slide rails, and can protrude from the side of the chair base 2, see the fifth figure. Before the shift, the seat belt group 8 and the seat belt belt set 7 are used to fix the user to the seat surface 1 and the seat back 4, and then the extension board 3 is pulled out from the chair base 2 to the wheelchair seat surface, and the extension is extended. The devil felt 14 on both sides of the board 3 is wrapped around the steel pipe on the side of the wheelchair seat, and then from the seat surface 1 The handles on both sides are towed, and then the assistant can tow the handles on both sides of the seat 1 to move the seat 1 together with the user on the chair from the original position of the user to the wheelchair, after completing the shifting action, Slide the extension plate 3 into the lower side of the chair base 2 by means of a slide rail. See the sixth figure. If no one is used, the seat back adjustment handle 13 can be pulled out to the outside, with the right rotary shaft 11 and the right rotary shaft key. 12, and the left rotating shaft 9 and the left rotating shaft are rotated by the key 10 to drive the seat back 4 to fold.
