Realización preferente de la invenciónPreferred Embodiment of the Invention

Este modelo está constituido por dos grupos de cuatro ruedas (1), uno a cada lado de la bolsa de la compra (2), que mediante un eje (3) se une a un rodamiento o casquillo (4) anclado a la estructura en forma de "ele" (5). La disposición en cruz de las cuatro ruedas (1) se hace por medio de dos perfiles metálicos (6) soldados entre sí, preferentemente tubo de sección rectangular por ser más resistente a la flexión; y del centro de la cruz soldado o atornillado sobresale el eje de giro (3).This model consists of two groups of four wheels (1), one on each side of the shopping bag (2), which by means of a shaft (3) it is attached to a bearing or bush (4) anchored to the structure in the form of "ele" (5). The cross arrangement of The four wheels (1) is made by means of two metal profiles (6) welded together, preferably rectangular section tube for being more resistant to bending; and from the center of the soldier cross or screwed, the pivot shaft (3) protrudes.

La estructura (5) se une a la del otro lado de la bolsa (2) por medio de travesaños (7) que dan rigidez al conjunto, y sirven de anclaje a los largueros (8) preferentemente tubo de sección circular, y a la pletina (9) que hace las veces de pata de apoyo cuando el carrito está parado. Los largueros (8) se unen en su parte superior por medio del travesaño (10), que sirve de empuñadura para que el usuario pueda manejar el carrito. Puede moverlo empujando o tirando de él, ya que las ruedas (1) giran libremente alrededor del tornillo o eje (11) que las fija a los extremos de los perfiles (6). Según se ve en la figura-3 en el movimiento del carrito, la rueda (1) que va delante girando sobre el suelo, puede topar con un obstáculo y sino lo pasa por encima, por la acción de la fuerza que ejerce el usuario se origina un par que obliga al grupo de ruedas (1) de ese lado, a girar alrededor del eje (3) en el sentido de avance.The structure (5) joins the one on the other side of the bag (2) by means of crossbars (7) that stiffen the set, and serve as an anchor to the stringers (8) preferably circular section tube, and to the plate (9) that acts as support leg when the cart is stopped. The stringers (8) are join at the top by means of the crossbar (10), which serves as handle so that the user can handle the cart. May move it by pushing or pulling it, since the wheels (1) turn freely around the screw or shaft (11) that fixes them to the profile ends (6). As seen in the Figure-3 in the movement of the cart, the wheel (1) that goes ahead turning on the ground, you can run into an obstacle and if not passes it over, by the action of the force exerted by the user originates a pair that forces the wheel group (1) of that side, to rotate around the axis (3) in the direction of advance.

Opcionalmente puede hacerse que el eje (3) sea el mismo para los dos grupos de ruedas (1), pasando de un lado a otro de la bolsa (2), pero en principio parece más ventajoso que sean independientes.Optionally, the shaft (3) can be made to be the same for the two groups of wheels (1), moving from one side to another of the bag (2), but in principle it seems more advantageous than Be independent.

Del mismo modo cuando el usuario tira del carrito para subir una escalera, las ruedas (1) que topan con el frontal del escalón, quedan sin poder avanzar y con la fuerza de tracción que ejerce el usuario, se origina un par que mueve todo el conjunto hasta que las otras ruedas (1) que están en el aire, se apoyan en el escalón superior y topan con su frontal, y así sucesivamente tal como se muestra en las figuras-4A -4B -4C y -4D.Similarly when the user pulls the cart to climb a ladder, the wheels (1) that run into the front of the step, they are unable to move forward and with the force of traction that the user exerts, a pair that moves all the set until the other wheels (1) that are in the air, are they rest on the upper step and run into their front, and so on successively as shown in figures-4A -4B -4C and -4D.

El rodamiento (4) está anclado cerca del vértice del ángulo recto que forma la estructura (5), para que cuando se suba la escalera con el carrito cargado, la vertical del centro de masas del conjunto, pase cerca del rodamiento (4) y del lado de donde está el usuario, para que el centro de masas no tire de la persona escaleras abajo mientras ésta sube los escalones.The bearing (4) is anchored near the vertex of the right angle that forms the structure (5), so that when climb the ladder with the cart loaded, the vertical of the center of mass of the assembly, pass near the bearing (4) and on the side of where is the user, so that the center of mass does not pull the person downstairs while it climbs the steps.

Esta disposición en cruz de cuatro ruedas (1) laterales, se puede aplicar al modelo descrito en U201000639 para transporte y manipulación de botellas de butano. Este modelo es perfectamente válido tal como está expuesto, sólo en el caso de subir escaleras es más ventajoso sustituir la rueda lateral grande por la disposición en cruz de cuatro ruedas (1) laterales más pequeñas. A modo de ejemplo para una altura del escalón de 20 cm. según modelo U201000639, es necesario usar una rueda de radio mayor de 20 cm., para que el par originado por la fuerza de tracción que ejerce el usuario, entre el eje de giro de la rueda y el punto de contacto de ésta con el frontal del escalón, posibilite hacer ascender la carga con menos esfuerzo. Para el mismo carrito, sustituyendo ésta rueda por un grupo en cruz de cuatro ruedas (1), la fuerza de tracción del usuario será menor porque la distancia entre el eje (3) de giro y el punto de contacto de la rueda (1) con el frontal del escalón es mayor.This four wheel cross arrangement (1) side, can be applied to the model described in U201000639 to transport and handling of butane bottles. This model is perfectly valid as stated, only in the case of climbing stairs is more advantageous to replace the large side wheel by the cross arrangement of four lateral wheels (1) more little. As an example for a step height of 20 cm. according to model U201000639, it is necessary to use a larger radius wheel 20 cm., so that the torque caused by the traction force that exerts the user, between the axis of rotation of the wheel and the point of contact with the front of the step, make possible ascend the load with less effort. For the same cart, replacing this wheel with a four wheel cross group (1), The user's tensile force will be less because the distance between the axis (3) of rotation and the contact point of the wheel (1) with The front of the step is larger.

Lo expuesto en éste ejemplo se puede aplicar a otros dispositivos para transportar cargas (paquetes, cajas, etc...), que en su trayecto hayan de salvar escalones y obstáculos similares.The above in this example can be applied to other devices for transporting loads (packages, boxes, etc ...), that in their journey they have to overcome steps and obstacles Similar.
