A standing-up assist device including: a base portion; a shaft portion, having one end connected to the base portion, capable of moving at least up and down; a support portion provided at another end of the shaft portion; a control unit for controlling movement of the shaft portion; and a user information input unit to which information of a user is input, wherein, when a speed at which the support portion moves when the user is standing up is defined as a first moving speed, the control unit changes the first moving speed according to at least any of physical information and health information of the user, which have been input from the user information input unit.

A wearable chair may include a foot frame configured to support a foot of a user; a shank link configured to rotatably connect to the foot frame; a connecting link provided in front of the shank link and configured to rotatably connect to the foot frame; a knee link configured to rotatably connect to each of the shank link and the connecting link; and a thigh link configured to extend from the knee link. The foot frame, the shank link, the connecting link, and the knee link constitute a four-bar linkage.

Systems and methods of wheelchair systems herein provide a wheelchair capable of providing a brace system that moves between retracted and deployed positions to provide a physical support to the legs of the user to assist the user in transition between a plurality of user positions. Embodiments determine a user request for such assistance and then either deploys and/or retracts the brace system. Embodiments provide for assistance independent of additional people, such as aides, to assist the user in moving or transitioning between the plurality of user positions while also allowing or permitting the wheelchair to function normally when the brace system is in the retracted position.

A lifting mechanism has a base to which a pivot of a parallelogram structure. A spring extends from a first link of the parallelogram to an adjustable termination point on a second link of the parallelogram to form a lifting triangle. The spring termination point is displaced from a main pivot of the parallelogram to create an adjustable “lever arm” to vary the lifting force. A lifting power adjustment mechanism adjusts the position of the spring termination point. An extension is in fixed relation to one of the parallelogram links and maintains its angle with respect to the horizontal when angles of the parallelogram are varied upon raising or lowering the lifting mechanism between a sitting mode and a standing mode. The extension serves as a base for a rear seat section. A front seat section is pivotally attached to the rear seat section allowing it to swing downward upon elevation of the lifting mechanism.

A toilet includes a base, a cover, and a seat. The seat is rotatably coupled to the base, and the cover is rotatably coupled to the seat. The cover and the seat define an angled axis that is oriented upward and forward toward a front end of the base. The cover and the seat are each configured to rotate about the angled axis between a lowered position in which the cover and the seat are located adjacent the base and a stowed position in which the cover and the seat are oriented in an upward direction.

An assisted standing and walking device for a user with at least one side paralysis or weakness is provided with provisions for assisted transitioning of the user from a seated position to a standing position prior to walking in the assisted standing and walking device with user friendly attachment and release with controlled limitation of lateral gait movement that occurs in lateral walking gait motion.
