Автор: Антон Анатольевич Михеев
Принадлежит: Общество с ограниченной ответственностью "Научно-производственное предприятие "КОЛОСС"

Полезная модель предназначена для беспрепятственного передвижения любых предметов на колесном ходу в местах, где имеются ограничения для установки стационарного пандуса или аппарели, например в подъездах зданий. Кроме того, описываемая полезная модель исключает необходимость установки стационарного пандуса, не имеющего возможности занимать сложенное состояние во вновь строящихся домах, что позволяет значительно сократить площадь подъезда, расширив при этом полезную площадь. Техническим результатом заявленного устройства является повышение срока службы складной электрической аппарели за счет стационарного размещения электропривода. Заявленный технический результат достигается тем, что в складной электрической аппарели, содержащей две платформы, соединенные между собой, по меньшей мере, двумя шарнирными соединениями, одна из которых закреплена при помощи опор с шарнирным соединением на опорной поверхности, по меньшей мере, один электропривод для складывания и раскладывания аппарели, она дополнительно содержит, по меньшей мере, одно средство перемещения по поперечной направляющей, соединенное посредством гибкой связи со стороны, противоположной шарнирному соединению с первой платформой, с другой платформой и, по меньшей мере, с одним электроприводом, жестко закрепленным на опорной поверхности. При этом в качестве средства перемещения может быть использована каретка. Складная электрическая аппарель может быть дополнительно снабжена, по меньшей мере, одной поперечной направляющей для перемещения каретки, которая соединена с платформой посредством регулируемой тяги. Одна из платформ по одному из краев может быть снабжена роликами. 3 з.п. ф-лы, 2 ил.

A collection of diagnostic and troubleshooting information associated with a power driven wheelchair is stored for access by a microcontroller to be displayed to a user to assist in troubleshooting the power driven wheelchair. A log of fault codes transmitted by various fault-detecting mechanisms is compiled. A user may request display of diagnostic information associated with a selected fault code. The operating instructions of a power driven wheelchair may be updated by using portable storage media onto which a latest version of operating instructions is loaded to transfer the updated operating instructions to wheelchair controller memory. The calibration of a power driven wheelchair can be simplified by providing functionality within the wheelchair controller to change calibration parameters or to transfer calibration parameters from portable storage media.

Drive-control systems for personal-transportation vehicles can function as active driving aids that enable autonomous and semi-autonomous cooperative navigation of electric-powered wheelchairs (EPWs) and other vehicles both indoors, and in dynamic, outdoor environments. The systems can help to compensate for the loss of cognitive, perceptive, or motor function in the driver by interpreting the driver's intent and seeing out into the environment on the driver's behalf. The systems can incorporate intelligent sensing and drive-control means that work in concert with the driver to aid in negotiating changing terrain, avoiding obstacles/collisions, maintaining a straight trajectory, etc. In addition, the systems can be configured to facilitate higher-level path planning, and execution of non-linear routes of travel in a safe and efficient manner.

A collection of diagnostic and troubleshooting information associated with a power driven wheelchair is stored for access by a microcontroller to be displayed to a user to assist in troubleshooting the power driven wheelchair. A log of fault codes transmitted by various fault-detecting mechanisms is compiled. A user may request display of diagnostic information associated with a selected fault code. The operating instructions of a power driven wheelchair may be updated by using portable storage media onto which a latest version of operating instructions is loaded to transfer the updated operating instructions to wheelchair controller memory. The calibration of a power driven wheelchair can be simplified by providing functionality within the wheelchair controller to change calibration parameters or to transfer calibration parameters from portable storage media.

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. 1. A method of using a rotatable swing arm assembly for folding wheelchairs , the method comprising the steps of:providing a foldable wheelchair having a first main wheel and a second main wheel;unfolding the foldable wheelchair from a closed configuration to an open configuration such that the first main wheel and the second main wheel define an axis of rotation when the wheelchair is in the open configuration;mounting a first end of a camber tube to the foldable wheelchair's frame such that the camber tube rotates with respect to the wheelchair's frame;rotating the camber tube from a first position, which is approximately perpendicular to the axis of rotation, to a second position, which is approximately parallel with the axis of rotation, such that the camber tube's second end aligns with a bracket mounted to the wheelchair; andsecuring the camber tube's second end to the bracket.2.
