Description

Изобретение относится к креслам-коляскам с сервоприводом для инвалидов, лишенных нижних конечностей или их подвижности.The invention relates to wheelchairs with a servo for people with disabilities, deprived of lower limbs or their mobility.

Известно шасси двухколесное кресла-коляски / Патент №2269992 кл. A61G 5/04, 5/00 от 07.06.2004/, содержащее несущую платформу системы сервоприводов ведущих бортовых колем и устройство стабилизации положения платформы в виде самоориентирующихся колес на концах пружинящего коромысла, размещенного между ведущими бортовыми колесами в продольной плоскости кресла-коляски.Known chassis two-wheeled wheelchair / Patent No. 2269992 class. A61G 5/04, 5/00 dated 06/07/2004 /, containing the supporting platform of the servo-drive system of the leading side wheels and a device for stabilizing the position of the platform in the form of self-orientating wheels at the ends of the spring-loaded rocker arm located between the leading side wheels in the longitudinal plane of the wheelchair.

При всех достоинствах конструкторской схемы известного шасси-прототипа последнее может быть усовершенствовано с целью повышения удобства эксплуатации инвалидом двухколесного кресла-коляски и расширения функциональных возможностей шасси.With all the advantages of the design scheme of the known prototype chassis, the latter can be improved in order to improve the ease of use of a disabled two-wheeled wheelchair and to expand the functionality of the chassis.

Заявленная цель решается тем, что в шасси двухколесном кресла-коляски, содержащем несущую платформу системы сервоприводов ведущих бортовых колес и устройство стабилизации положения платформы в виде самоориентирующихся колес на концах пружинящего коромысла, размещенного между ведущими бортовыми колесами в продольной плоскости кресла-коляски, коромысло выполнено в виде четырехшарнирного механизма, два шарнира которого имеют свободу перемещения вдоль оси ведущих бортовых колес, а два других шарнира имеют свободу перемещения эквидистантно от оси или к оси ведущих бортовых колес.The stated goal is solved by the fact that in the chassis of a two-wheeled wheelchair, containing the supporting platform of the servo-drive system of the driving side wheels and a device for stabilizing the position of the platform in the form of self-orientating wheels at the ends of the spring beam located between the leading side wheels in the longitudinal plane of the wheelchair, the rocker is made in in the form of a four-hinged mechanism, two hinges of which have freedom of movement along the axis of the driving side wheels, and two other hinges have freedom of movement of equidist coagulant from the axis or to the axis of the leading board of the wheels.

Предлагаемое изобретение иллюстрируется чертежом, общий вид сверху на шасси кресла-коляски.The present invention is illustrated in the drawing, a General top view of the chassis of a wheelchair.

Предлагаемое шасси двухколесное кресла-коляски содержит несущую платформу системы сервоприводов ведущих бортовых колес (1 и 2) и устройство стабилизации положения платформы в виде самоориентирующихся колес (3 и 4) на концах пружинящего коромысла 5, размещенного между ведущими бортовыми колесами (1 и 2) в продольной плоскости кресла-коляски. При этом коромысло 5 выполнено в виде четырехшарнирного механизма, два шарнира (6 и 7) которого имеют свободу перемещения вдоль оси ведущих бортовых колес (1 и 2), а два других шарнира (8 и 9) имеют свободу перемещения эквидистантно от оси или к оси ведущих бортовых колес (1 и 2).The proposed chassis two-wheeled wheelchair contains a supporting platform of the servo-drive system of the driving side wheels (1 and 2) and a device for stabilizing the platform in the form of self-orientating wheels (3 and 4) at the ends of the spring arm 5 located between the leading side wheels (1 and 2) in the longitudinal plane of the wheelchair. In this case, the rocker 5 is made in the form of a four-hinged mechanism, two hinges (6 and 7) of which have freedom of movement along the axis of the driving side wheels (1 and 2), and the other two hinges (8 and 9) have freedom of movement equidistant from the axis or to the axis driving side wheels (1 and 2).

В представленном на чертеже положении коромысла 5 с шарнирами (6-7 и 8-9) удобно поворачиваться-разворачиваться даже на песчаной и/или заснеженной дороге на предлагаемом шасси кресла-коляски, так как пятна контакта всех колес кресла-коляски равноудалены от геометрического центра шасси в плане. При резком старте или торможении кресла-коляски лучшим из возможных положений шарниров (6 и 7), скользящих вдоль оси ведущих бортовых колес (1 и 2), будет максимально близкое положение к продольной плоскости кресла-коляски. Самоориентирующиеся колеса (3 и 4) на концах пружинящего коромысла 5 при этом будут максимально удалены от оси ведущих бортовых колес (1 и 2), что способствует повышению устойчивости и удобству эксплуатации инвалидом двухколесных кресел-колясок и расширяет функциональные возможности шасси по предлагаемому изобретением техническому решению.In the position of the rocker arm 5 with hinges (6-7 and 8-9) shown in the drawing, it is convenient to turn and unfold even on a sandy and / or snowy road on the proposed wheelchair chassis, since the contact spots of all wheels of the wheelchair are equidistant from the geometric center chassis in plan. With a sharp start or braking of the wheelchair, the best possible position of the hinges (6 and 7), sliding along the axis of the drive side wheels (1 and 2), will be as close as possible to the longitudinal plane of the wheelchair. The self-orientating wheels (3 and 4) at the ends of the spring rocker 5 will be maximally removed from the axis of the driving side wheels (1 and 2), which helps to increase stability and ease of operation of a disabled two-wheeled wheelchair and expands the functionality of the chassis according to the technical solution proposed by the invention .

Устройство управления четырехшарнирным механизмом и фиксации его положения на чертеже не показаны и составляет авторское ноу-хау.The control device of the four-hinged mechanism and fixing its position on the drawing are not shown and is the author's know-how.

Таким образом, по мнению заявителя, предлагаемое изобретением техническое решение является новым, имеет изобретательский уровень и промышленно применимо.Thus, according to the applicant, the technical solution proposed by the invention is new, has an inventive step and is industrially applicable.
