A wheelchair includes a seat, a first adjustable leg coupled to a first side of the seat, a second adjustable leg coupled to a second side of the seat, one or more turning sensors, and a control unit. The first adjustable leg includes a first leg actuator configured to extend and retract the first adjustable leg. The second adjustable leg includes a second leg actuator configured to extend and retract the second adjustable leg. The one or more turning sensors are configured to output a turning signal indicative of the wheelchair performing a turning motion. The control unit is operable to determine the wheelchair is performing the turning motion based on the turning signal, and automatically adjust a tilt angle of the seat with the first leg actuator and the second leg actuator to lean a user of the wheelchair into the turning motion.

This invention comprises a low cost, high strength sit-to-stand wheel chair assembly. It is comprised of a base with an upward extension formed of a linear actuator mounted within telescopic members. The telescopic members carry large wheels together with a linkage operated front wheels that are mounted on the forward position of the base. A power linear actuator assembly causes the telescopic members to extend and retract to move the wheelchair assembly from the mobile position to a raised position that permits the base to engage the floor surface and to assist the patient to move from a sitting position to a standing position.

A first transport apparatus includes a deck for supporting a patient thereon and a lift mechanism supporting the deck. The deck is removable from the lift mechanism for use as a second transport apparatus or part of a second transport apparatus. The first transport apparatus further includes an electrically powered device at the first transport apparatus, and a user input device for wireless control of the electrically powered device, which is operable at or near the first transport apparatus and the second transport apparatus.

A drive device for a wheelchair includes a control element, a chassis and a support frame. A fixing arrangement is mounted on the support frame and can be fixed to a wheelchair frame of the wheelchair. The fixing arrangement is designed such that it can be automatically connected to and released from the wheelchair frame of the wheelchair by a fixing drive.

A user control device for a transporter. The user control device can communicate with the transporter via electrical interface(s) that can facilitate communication and data processing among the user interface device and controllers that can control the movement of the transporter. The user control device can perform automated actions based on the environment in which the transporter operates and the user's desired movement of the transporter. External applications can enable monitoring and control of the transporter.

A displacement mechanism contains: a support rack, a sitting assembly, a slide rod, two fixing feet, a back, a first holding plate, a second holding plate, and an expandable sheet. The support rack includes a fixer having a post, a rolling stand having multiple first rollers, and a lifter. The sitting assembly includes a receiving orifice and a rotatable mounting. The slide rod includes an elongated hole for connecting the slide rod with the post. A respective foot includes a second roller. The back is disposed on a rear end of the sitting assembly. The first holding plate is mounted on a seat of a wheelchair, and the sitting assembly is slid between the fixer and the first holding plate. The second holding plate is connected on a seat of a car. The expandable sheet is disposed between the fixer and the second holding plate.

A wheelchair incorporated with a lift apparatus is disclosed. The wheelchair comprises a pair of seat frame support bars, backrest support bars, and armrest frame support bars for supporting at least one seat cushion, backrest cushion, and armrest cushions. The wheelchair further comprises lower support bars positioned parallel and opposite each other on both sides of the wheelchair. The support assembly includes a plurality of scissor links pivotally connected to each other, and an end of the plurality of scissor links is pivotally affixed with needle bearings to the lower support bars and the seat frame support bars. The lift apparatus includes one or more actuators, positioned between the lower support bars and at least one scissor link on both sides. The actuators are configured to raise and lower the seat cushion by raising at least one scissor link, thereby raising and lowering the seat cushion to a desired adjustable height for the user.

An improved sit-to-stand wheelchair having a base for engaging a surface and carrying a power actuated elevating drive supporting a patient seat and a wheels with improved footrests that may be retractable, said power actuated elevating drive simultaneous elevating the seat and lowering the base into fixed engagement with a surface when the patient desires to move to a standing position.

A swinging playground device includes a swing platform. The swinging playground device also includes a skirt coupled to the swinging platform and fills an area below the swinging platform as the swinging platform moves in a swinging motion.

A transport apparatus has a mobile chassis, a lifting mechanism, two armpit supports structured and operated mirror-symmetrical to one another, and two seat assemblies. The lifting mechanism includes a lifting arm for assembling a chest rest and two lifting racks, and a linear actuator driving the lifting arm to pivot upward or downward. The armpit supports are assembled on the lifting racks and transversely extend toward a rear of the mobile chassis. The seat assemblies are assembled on the mobile chassis. Each of the seat assembly has a seat plate driven to rotate by a drive motor to form a seat. The weak person can be moved directly by the transport apparatus with voice command or with a remote control. Since the weak person is not moved by the care workers, the weak person can be moved in an easier and safer way.
