Implementation

Reference will now be made in detail to examples of the present creations which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

Please refer to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, and Fig. 6, the transfer device of the wheelchair of this creation is composed of a base frame 1, a lifting unit 2, and a transfer unit 3 for the convenience of users move, where:

There are runners 11 on both sides of the base frame 1, and between the runners 11 on both sides, a support frame 12 is provided. Two auxiliary wheels 121 are arranged on the bottom of the front of the support frame 12, and an adjustable wheel is provided behind the support frame 12. The hand push handle 13 for raising and lowering is provided with a lever switch 131 at the middle position of the hand push handle 13, which can adjust the position of the hand push handle 13 rising or falling.

The lifting unit 2 is set between the two runners 11 of the base frame 1. It is the center of the support frame body 12 installed between the two runners 11, and a control valve 21 is provided at the bottom, which can be stepped or pressed. In this way, the moving member 22 can be moved up and down by operating the control valve 21, and a seat cushion 23 is provided above the moving member 22, and the seat cushion 23 forms upper and lower seat bodies 231, 232, and the upper seat body 231 has a stopper 233 on one side.

The transfer unit 3 is arranged on the bottom of the upper base body 231, has a positioning seat 31, and is connected with track rods 32 on both sides of the positioning seat 31, and the sides of the two track rods 32 are fixed in the lower base body 232, and can The active dragging and telescoping is used for the sliding displacement of the upper base body 231 on the track bar 32 .

And through the wheelchair transfer device composed of the above-mentioned base frame 1, lifting unit 2, transfer unit 3, etc., the occupant can sit comfortably on the seat cushion 23 of the wheelchair, and can easily slide and displace. Wherein the lifting unit 2 can be a pneumatic cylinder, a hydraulic cylinder or a lifting screw, a rack driven by a gear, etc. The lifting unit 2 and the moving member 22 can be moved up and down.

When the wheelchair of this creation is in use, if you want to transfer the occupant to the bed, you can transfer the occupant through the following steps:
