A lift chair includes a chair frame, a stationary base section, and a motorized lift mechanism. Engagement of the motorized lift mechanism causes movement of a lift frame which is connected to the chair frame to cause movement from a first recumbent position to a second tilted position and allowing the user to be assisted to a standing position. Preferably, the chair can be rocked back and forth longitudinally, with the rocking motion being disabled while the lift mechanism is engaged. According to another preferred aspect, the chair can include a reclining back section which operates independently of the lift mechanism.
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.
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.
Passive gravity balancing orthosis apparatus for assisting and training patients suffering from muscle weakness by relieving the patients afflicted member of its weight using a plurality of articulated supporting members. Relief is obtained by identifying and fixing the center of mass of the combined articulated equipment members and supported weight of the patient's member in space using a defined parallelogram mechanism and once so identified making the total potential energy for any configuration of the articulated members of the system constant. At least one zero free length spring is used to connect the center of mass to a support outside the articulated members. Additional springs connect the center of mass to the articulated members.
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.
