Abstract
Dispositivo de rodadura para vehículos automóviles y sillas de ruedas, que comprende una pieza resistente en forma general de "Z'' cuyas ramas extremas presentan sendos taladros en los que se acoplan los ejes de sendas ruedas de igual diámetro y que van acopladas a cada uno de los laterales de las sillas de ruedas. En la rama central e inclinada de la "Z'' emerge perpendicularmente un eje fijo en el que se monta una rueda dentada conductora de una transmisión de movimiento y giro de las ruedas, encontrándose este eje fijo y los ejes de las ruedas alineados horizontalmente. El eje de la rueda delantera constituye el eje de giro del dispositivo cuando la rueda delantera hace tope con un obstáculo, en cuyo instante la rueda trasera juntamente con la estructura de la silla gira hacia delante transformándose la rueda trasera en rueda delantera.Rolling device for motor vehicles and wheelchairs, comprising a resistant piece in a general "Z" shape, the end branches of which have separate holes in which the axles of two wheels of equal diameter are coupled and which are coupled to each one of the sides of the wheelchairs. In the central and inclined branch of the "Z" a fixed axis emerges perpendicularly in which a cogwheel conductive of a transmission of movement and rotation of the wheels is mounted, being this fixed axis and the axles of the wheels aligned horizontally. The axis of the front wheel constitutes the axis of rotation of the device when the front wheel comes into contact with an obstacle, at which time the rear wheel together with the chair structure rotates forward, transforming the rear wheel into a front wheel.
