Rotatable Swing Arm Stabilizer Assembly For Folding Wheelchairs
20180000668 · 2018-01-04 ·

A swing arm assembly for a foldable wheelchair consisting of a camber tube and adapters is disclosed. The adapters mount to the frame of the wheelchair and receive the ends of the camber tube. One end of the camber tube is pinned into an adapter such that it pivots. The other end is pinned in an adapter using a quick release pin. The camber tube improves the stability of the foldable wheelchair. When desired to fold the wheelchair, the quick release pin is removed and the camber tube is rotated approximately 90 degrees, thereby allowing the wheelchair to fold. The adapters may be mounted to the wheelchair frame or to stub axles if used. The swing arm assembly adds substantial stiffness and stability to a folding wheelchair.

The main body is maintained in a standing state while driving by the connection to the module to be towed. A personal mobility and a control method thereof utilize the towing module.

Removable power assist for manual wheelchair

Apparatus and associated methods relate to a removable power assist for converting a manual wheelchair into an electronic wheelchair, based on configuring a friction roller to releasably engage with a wheelchair wheel, configuring the friction roller when engaged to drive the wheel through a contact surface with the wheel above the wheel center and behind the wheelchair seating area, configuring a motor to rotate the friction roller, and moving the wheelchair based on engaging the friction roller and activating the motor to turn the wheel through force by the friction roller against the contact surface with the wheel. The power assist may include a user-operable lever configured to engage or disengage the friction roller without a user leaving their seated position in the wheelchair. Configuring the friction roller above the wheel center and behind the wheelchair seating area may permit collapsible wheelchair folding or unfolding without uninstalling the power assist.

An apparatus a and method for networked transportation of patients or people with impaired mobility in a hospital bed, or nursing bed, having the following method features: a) a patient in question or an applicable caregiver is reported by a control centre as in need of transportation from one ward A to another ward B, b) the nursing staff on ward A beds down or puts the person in question into a special transportation bed or a special transportation chair and reports to the control centre when this person is correctly supported, this being able to be checked by means of a pressure sensor (23) in the lying area or sitting area, the identity being ensured by the nursing staff or being able to be checked by means of a patient identity card, c) the patient is automatically moved to ward B, d) the patient is brought to his treatment in ward B and then transported back to ward A by the same route.

Electrical power assistance device for transport wheelchair
11607354 · 2023-03-21 · ·

An electrical power assistance device designed to be removably coupled to existing transport wheelchairs to provide electric power to aid in transportation of a person sitting in the wheelchair, while being detachable to allow the transport chair to fold up for easy storage in a car or other vehicle. The electrical power assistance device includes a motor powered by a rechargeable battery, where the motor drives an internal shaft which rotates a pair of friction wheels. A clutch, provided on a separate axle coupled to the friction wheels by eccentric disks, allows the friction wheels to engage or disengage with the rear wheels of the transport wheelchair.

CHASSIS STRUCTURE FOR AN ELECTRIC POWER WHEELCHAIR
20230083107 · 2023-03-16 ·

A chassis structure for an electric power wheelchair adapted for a seat frame to be mounted and supported thereon includes a chassis housing which defines an accommodation space, and an upper cover which covers an upper opened end of the accommodation space. At least one modular raising strip assembly is removably sandwiched between the chassis housing and the upper cover and has a predetermined thickness such that a volume of the accommodation space is increased with the raising strip assembly. With the modular raising strip assembly, the volume of the accommodation space is adjustable according to the battery capacity of a battery pack of a drive unit which is mounted in the accommodation space to meet the user's requirement.

EXCHANGEABLE UNIVERSAL WHEELCHAIR POWER ASSIST

Apparatus and associated methods relate to a wheelchair power assist device configured to be installed, uninstalled and exchanged using an exchange tab welded to a wheelchair, and when installed to switch a motorized friction roller between engaged and disengaged modes with a wheelchair wheel, based on an engagement actuator configured to move the friction roller relative to the wheelchair. The friction roller may be operably coupled with an engagement member configured to move relative to the wheelchair. The engagement member may be moved by an extendable and retractable actuator shaft coupled with the wheelchair. A manual wheelchair may be converted to a powered wheelchair using a motorized friction roller for each wheelchair wheel while leaving an open space behind the wheelchair seating area, advantageously permitting the power assist devices to remain attached to a foldable wheelchair in either folded or unfolded configurations.
