A transport chair of this disclosure includes a frame having a pair of fixed sides and hinged sides, the frame moveable between stowed and deployed states. The frame includes wheel receiving means and armrest and push handle assemblies receiving means with quick connect-disconnect clamps or pins. A bar, which is connectable to, and detachable from, each hinge extends between the pair of hinged sides. When connected to the hinged sides, the bar locks the frame in the deployed state and prevents the frame from moving to the stowed state. The chair may be quickly assembled and then dissembled for storage without the need for tools. When dissembled, the transport chair fits within an envelope 9 inches deep×14 inches wide×22 inches long.

A folding wheelchair comprising a luggage compartment, a collapsible frame and wheels, the wheels being mounted to a chassis of the collapsible frame for supporting the folding wheelchair in use, the collapsible frame having a first support pivotally mounted to the chassis at a first end of the first support, the first support and chassis being configured to rotate relative to one another between a stowed position, in which the chassis and the first support are adjacent, and an erect position in which the first support extends away from the chassis to support a seat and handles for pushing the folding wheelchair.

A kit of parts which when assembled will provide a wheeled chair and include a central frame member to which all other elements are connected.

A walker with an automated power drive system is disclosed. The walker comprises a rigid frame comprising a left grip and a right grip; a plurality of wheels affixed to the rigid frame; a plurality of drive motors integrally mounted in the plurality of wheels; and a drive motor controller configured to power the plurality of drive motors. The drive motor controller is configured to: determine the orientation of the walker; generate a first motor current component to compensate for orientation of the walker and the resulting torque on the drive motor; determine the speed of the walker, generate a second motor current to component for internal friction based on the speed of the walker; determine a user force applied to the left grip and right grip; generate a third motor current component for the drive motors based on the user force applied to the left grip and right grip; and power the drive motors based on a sum of the first motor current component, second motor current component, and third motor current component. The drive motor controller is configured to determine the user force applied to the left grip and right grip based on a measured current from the drive motors. Specifically, the drive motor controller is configured to determine the user force applied to the left grip and right grip based on a difference between a target current provided to the drive motors and the actual current utilized by the drive motors.

A kit of parts which when assembled will provide a wheeled chair and include a central frame member to which all other elements are connected.

A mobility aid, comprising a first frame member, a second frame member, and at least one pivoting member, which is connected to the first frame member and is pivotably mounted about a pivot axis to the second frame member. The pivoting member can be moved into a use position and into a transport position relative to the second frame member. A first locking device locks the pivoting member relative to the second frame member whenever the pivoting member is in the use position. A second locking device locks the first frame member relative to the second frame member whenever the pivoting member is in the transport position.

A wheelchair can comprise a frame and a plurality of wheels rotatably attached to the frame, and a motor coupled to the frame. A power source can be configured to power the motor. A drive shaft can be coupled to the motor. A first sprocket can be coupled to the drive shaft. A second sprocket can be configured to be rotationally fixed to a wheel of the plurality of wheels. A drive belt or chain can extend between the first sprocket and the second sprocket. An input device can be configured to receive an input from an operator and, in response to receiving the input, cause the motor to rotate.

A patient transport apparatus for transporting patients in a stair configuration and in a chair configuration. A multiple mode handle assembly is provided for user engagement, and is movable between a first handle configuration, a second handle configuration, and a third handle configuration.

A collapsible mobility aid with two frame elements, on each of which at least one wheel is secured or can be secured, and with a folding mechanism by which the frame elements are connected to each other, and a distance between the frame elements in a first position of the folding mechanism can be adapted to a transport distance and in a second position of the folding mechanism can be adapted to a use distance, wherein the folding mechanism has a central element with a slide arranged moveably with respect thereto, at least two connection arms which are each articulated on a frame element and on the central element, and at least two levers which are each articulated on a connection arm and on the slide, wherein the swivel axes, about which the levers are arranged on the connection arms and the slide such that they can be swiveled, are on one plane when the folding mechanism is in the second position.

The invention discloses an electric wheelchair DYYJBHD20, which belongs to the technical field of medical equipment, and includes a backrest tube. The backrest tube is provided on a seat assembly. Armrest components are provided on the left and right sides of the backrest tube. On the seat assembly, the front end of the seat assembly is connected to the front wheel through a front fork connection assembly, and the rear end of the seat assembly is connected to the rear wheel through a rear frame. A matching foot pedal is provided at the front fork connection assembly, and at the rear wheel Used with auxiliary wheels. As a new structural design, the electric wheelchair DYYJBHD20 has a small folding volume and light weight, and uses the latest material, carbon fiber, which is very convenient to optimize the appearance of the entire vehicle. At the same time, the density of the carbon fiber material is about of aluminium alloy, greatly reducing the weight of the entire vehicle.
