Abstract: A seat elevating mechanism for chair particularly designed for old men and patients having weak legs mainly includes a seat that can be elevated or lowered using a power-actuated telescopic lifter. The seat is maintained in a horizontal position while being elevated or lowered, so that a user may stably sit thereon until the seat is fully elevated or lowered to enable the user to get up or sit down effortlessly.

Abstract: A stand-up bedside hoisting apparatus includes a base; three legs fixedly connected an inner ends to the base to stably support the entire hoisting apparatus; a pivoted-arm mechanism including a lower rotary shaft that is rotatable relative to the base within a safe angular range, and an upper suspension arm that can be turned up and down relative to the rotary shaft; and a hanger pivotally connected to a front end of the suspension arm for holding a hoisting carriage to carry and move a patient. The hoisting apparatus may be easily and conveniently erected to stand up at one side of a sickbed without the need of being fixedly mounted to a wall or floor, and could therefore be moved for use at any place as necessary.

Abstract: A walker particularly suitable for rehabilitation of a patient's legs includes a base provided with casters, a pair of handlebars, and a suspension frame for holding a safety belt. A leg separator is height-adjustably connected to the base to locate between and separate apart the patient's two legs, so that a cerebral palsied patient may bear inner sides of two legs against two lateral sides of the leg separator during practicing walking. Direction control members adapted to limit the casters to rotate forward and backward only are provided on the base to effectively enable the cerebral palsied patient to practice walking straightly forward.

Abstract: A power-actuated chair-type elevating apparatus for moving a user to a desired position includes a slidable base having an upright lower tube-extended from a top thereof, a table having a downward extended upper tube axially movably covering the lower tube, an elevating mechanism mounted in the upper and lower tubes to elevate or lower the table relative to the base, and a seat pivotally supported on two bent tubes and three links. The bent tubes are fixedly connected at another end to the upper tube. The three links are coaxially and pivotally connected at a first end to one another, and pivotally connected at a second end to the seat, the base, and the upper tube, respectively. When the table is elevated, the seat is also elevated and forward inclined for the user sit thereon to lean against the table without the risk of falling off the seat.

Abstract: A toilet seat lifting mechanism includes an upstanding base frame, a movable frame pivotally connected at a front end to a top front of the base frame, a toilet seat support pivotally connected at a rear edge to a rear end of the movable frame, and a toilet seat pivotally connected at a rear end to the rear edge of the toilet seat support to flatly position on a top of the toilet seat support. A lifter is mounted to one side of the base frame to gradually lift the rear end of the movable frame, so that the toilet seat support and the toilet seat are forward inclined to gradually move a user sitting on the toilet seat into an upstanding position.

Abstract: An elevating mechanism for assisting patient in using a toilet alone includes a base having a left and a right side frame, on which four links and an extension arm are symmetrically provided. When the two symmetrical extension arms are actuated, the four links on both side frames are lifted to ascend a seat and two armrests, so that an aged or a patient sat on the seat is lifted to an almost upstanding position without the need of supporting his or her weight completely on two weak legs.
