Abstract: A wheelchair shifting aid, mounted on a base of a wheelchair, comprising a seat, a central gliding track, two connecting plates, and several lateral guiding tracks. The seat is mounted on an upper side of the base. The central gliding track is located between the base and the seat, guiding the seat towards a front side of the wheelchair, then towards left and right sides of the wheelchair. The two connecting plates are hingedly connected with the base on two sides thereof, being able to be placed in horizontal positions, forming a single plane with the base. The several lateral guiding tracks are placed on the two connecting plates, guiding the seat to glide on the connecting plates. Thus the seat is guided towards a lateral side of the wheelchair.

Abstract: A sickbed, comprising: a first bed frame, provided with a plurality of fixed bed planks of mutual distance to support the patient's body and allow him to sit up or lift the legs, thus changing his posture; a second bed frame, vertically movably mounted below the first bed frame; a plurality of movable bed planks, which are mounted on said second bed frame, at a suitable height above said second bed frame, keeping certain distances from each other and being placed in gaps between said fixed bed planks; a first driving device to drive the second bed frame's movement up and down; and a second driving device to drive the first bed frame. Its improved parts include two lateral turning frames to help the patient to turn around, each further comprising a shaft and a plurality of parallel support planks of mutual distance, which are mounted on said shaft, placed in gaps between the fixed bed planks and the movable bed planks, and are movable in a rotary movement as driven by said shaft.
