A continuación se describe un carro de la compra seleccionado haciendo referencia a las figuras de la 1 a la 8. Next, a selected shopping cart is described with reference to the figures from 1 to 8.
En el carro 1 de la figura 1 se aprecia el asa 2 que forma parte del bastidor 3 que a su vez lleva incorporadas dos pletinas 4 (una a cada lado) que soportan las dos ruedas traseras. El número 6 muestra el manillar de dirección que dirige a la rueda tractora 7. El manillar incorpora también el acelerador, el freno y el voltímetro (tapados en esta figura por la cubierta 9 que puede cubrirlos para su protección). La bolsa 8 cubre por su parte inferior el conjunto de mecanismos y batería; la parte superior es para la carga de mercancías con su tapa/cubierta 10. En la figura 2 puede apreciarse la parte posterior del carro 1 donde se aprecian de forma más clara algunos elementos. El asa 2 y el bastidor 3 forman un conjunto sobre el cual pueden girar las dos pletinas 4 en los puntos de giro 1 1 para desplazar las dos ruedas 5 al desplegar el carro 1 . Las dos pletinas 4 forman un conjunto con las dos ruedas 5. La rueda de dirección y tracción es la 7. Bolsa 8 y protección 9 que cubre el manillar 6. El conjunto 13 es para el bloqueo del carro 1 cuando está desplegado como se verá más adelante. In the carriage 1 of Figure 1, the handle 2 can be seen, which is part of the frame 3 which in turn has two plates 4 (one on each side) that support the two rear wheels. The number 6 shows the steering handlebar that directs the tractor wheel 7. The handlebar also incorporates the accelerator, the brake and the voltmeter (covered in this figure by the cover 9 that can cover them for protection). The bag 8 covers on the bottom the set of mechanisms and battery; the upper part is for the loading of goods with its cover / cover 10. In figure 2 the rear part of the carriage 1 can be seen where some elements can be seen more clearly. The handle 2 and the frame 3 form an assembly on which the two plates 4 can rotate at the pivot points 1 1 to move the two wheels 5 when the carriage 1 is deployed. The two plates 4 form an assembly with the two wheels 5. The steering and traction wheel is 7. Bag 8 and protection 9 that covers the handlebar 6. The assembly 13 is for locking the carriage 1 when it is deployed as will be seen later.
El carro desplegado se muestra en la figura 3 preparado para transportar y ser conducido por una persona. El asa 2 y el bastidor 3 (retenidos por el trinquete 24) se abaten manualmente hacia abajo con punto de giro sobre 21 . A su vez sobre este conjunto giran las dos pletinas 4 en los puntos 1 1 para desplazar las ruedas 5 hacia atrás (forman un conjunto con 4). La rueda de dirección y tracción está representada con el número 7. La bolsa 8 con su tapa/cubierta 10 y protección 9 que puede cubrir el manillar 6, maneta de freno 12, voltímetro 22 y acelerador 20. El orificio 15 en la bolsa 8 es para alojar al tubo/soporte 14 del asiento cuando se pliega el carro; en este último tubo 14 se aloja el tubo 16 y sobre éste el asiento 17 y ambos se guardan en la bolsa 8 cuando el carro esta plegado. El 18 muestra una base con antideslizante para los pies del conductor y una rejilla 19 para el soporte de objetos/paquetes o maleta (omitida en otras figuras por claridad). El bloqueo entre el chasis 30 y el bastidor 3 cuando está abierto el carro se realiza mediante la pletina 13 con punto de giro en 23. Esta pletina 13 efectúa el bloqueo tal como se indica en el círculo enmarcado en 13 (un orificio en la pletina en el cual se introduce un pitón sujeto en el bastidor 3). Cuando el carro está completamente abierto el asa 2 descansa sobre el conjunto 4 encima del eje de las ruedas 5. The deployed carriage is shown in Figure 3 prepared to transport and be driven by a person. Handle 2 and frame 3 (retained by ratchet 24) are manually folded down with pivot point about 21. In turn, the two plates 4 rotate at points 1 1 to move the wheels 5 backwards (they form a set with 4). The steering and traction wheel is represented with the number 7. The bag 8 with its cover / cover 10 and protection 9 that can cover the handlebar 6, brake lever 12, voltmeter 22 and accelerator 20. The hole 15 in the bag 8 it is to accommodate the seat tube / support 14 when the car is folded; in this last tube 14 the tube 16 is housed and on it the seat 17 and both are stored in the bag 8 when the car is folded. The 18 shows a base with non-slip for the driver's feet and a rack 19 for the support of objects / packages or suitcase (omitted in other figures for clarity). The blockage between the chassis 30 and the frame 3 when the carriage is open is carried out by means of the plate 13 with pivot point at 23. This plate 13 performs the blocking as indicated in the circle framed in 13 (a hole in the plate in which a python is inserted in the frame 3). When the carriage is completely open, the handle 2 rests on the assembly 4 on the axis of the wheels 5.
La figura 4 muestra de forma esquemática el carro desplegado sirviendo para enseñar especialmente la forma de apertura de las ruedas traseras y el bloqueo del conjunto mediante la pletina 13 teniendo el eje en 23 y en tensión mediante el muelle 26 contra el bastidor 3. El trinquete 24 sirve para mantener el bastidor 3 en posición de carro plegado: presionando hacia abajo sirve para abrir el carro. Dicho trinquete 24 acciona al mismo tiempo al trinquete 25 (unido mediante una flecha/cable) liberando al conjunto 4 junto con las ruedas 5. Figure 4 schematically shows the carriage deployed serving especially to show the way of opening the rear wheels and blocking the assembly by means of the plate 13 having the axle at 23 and in tension by means of the spring 26 against the frame 3. The ratchet 24 serves to keep the frame 3 in the folded carriage position: pressing down serves to open the carriage. Said ratchet 24 simultaneously drives the ratchet 25 (joined by an arrow / cable) releasing the assembly 4 together with the wheels 5.
En la figura 5 se aprecia en forma aclaratoria un intermedio de la apertura del carro y el desplazamiento de las ruedas traseras. In figure 5 an intermediate of the carriage opening and the displacement of the rear wheels can be seen in clarification.
La figura 6 muestra el conjunto de mecanismos de dirección, tracción y freno. Estos mecanismos están protegidos por la cubierta/caja de la figura 7 (de fibra de vidrio u otro material similar y liviano) la cual aloja en un costado la batería que suministra energía al conjunto (no mostrada). Este conjunto está principalmente formado por un chasis 30 que soporta al conjunto 28 que comprende al motor con reductora 31 que transmite la energía a la rueda 7 por la cadena 29 (que también podría ser una correa). Todos estos elementos son controlados desde el manillar 6 en el que están ubicados el acelerador 20, maneta de freno 12 y voltímetro 22. El trinquete 24 mantiene sujeto al bastidor 3 cuando está plegado el carro. Aquí se puede apreciar el tubo/soporte 14 donde se coloca el tubo 16 y asiento 17 cuando se despliega el carro. Resumiendo: para la apertura o despliegue del carro basta presionar el trinquete 24 liberando al bastidor 3 y a su vez desde dicho trinquete 24 (está unido por una flecha/cable al trinquete 25) y libera por medio de éste al conjunto de ruedas 4 y 5. Se hace hincapié en que basta accionar el trinquete 24 para desencadenar la apertura total del carro. Con el carro plegado se puede accionar para ponerlo en marcha y acarrear solo la carga sujetándolo por el asa 2 y manejándolo con los mandos ubicados en el manillar 6. Los mecanismos ubicados en la parte inferior están protegidos por una caja/cubierta mostrada en la figura 7. La bolsa 8 va sujeta en la placa/soporte 27 y en su parte inferior descansa sobre el chasis 30 y caja/cubierta fig.7 cubriendo todo el conjunto. Figure 6 shows the set of steering, traction and brake mechanisms. These mechanisms are protected by the cover / box of Figure 7 (fiberglass or other similar and lightweight material) which houses on one side the battery that supplies power to the assembly (not shown). This assembly is mainly formed by a chassis 30 that supports the assembly 28 comprising the motor with gearbox 31 that transmits the energy to the wheel 7 by the chain 29 (which could also be a belt). All these elements are controlled from the handlebar 6 in which the throttle 20, brake lever 12 and voltmeter 22 are located. The ratchet 24 holds the frame 3 when the carriage is folded. Here you can see the tube / support 14 where the tube 16 and seat 17 are placed when the carriage is deployed. Summarizing: for opening or unfolding the carriage, simply press the ratchet 24, releasing the frame 3 and in turn from said ratchet 24 (it is connected by an arrow / cable to the ratchet 25) and release the wheel assembly 4 and 5 through it. It is emphasized that it is enough to operate the ratchet 24 to trigger the total opening of the car. With the folded carriage, it can be operated to start it and carry only the load by holding it by the handle 2 and handling it with the controls located on the handlebar 6. The mechanisms located at the bottom are protected by a box / cover shown in the figure 7. The bag 8 is held in the plate / support 27 and in its lower part rests on the chassis 30 and box / cover fig. 7 covering the whole assembly.
El sistema eléctrico se muestra por bloques en la figura 8. El controlador electrónico 35 del motor es alimentado por la batería 32 a través del fusible 33 y del automático 34. Dicho controlador 35 está regulado por el acelerador 20 proporcionando más o menos corriente al motor 31 moviendo su eje desde parado hasta poder alcanzar su máxima velocidad. El mando de freno 12 actúa doblemente: al accionarlo corta la salida del controlador 35 al motor 31 y acciona mecánicamente (mediante un cable/flecha) al freno ubicado en la rueda tractora 7. Existe un voltímetro 22 ubicado en el manillar 6 para conocer en todo momento el estado de carga de la batería 32 e igualmente lleva instalada una alarma 36 para alertar en el caso de sobrepasar el umbral mínimo de la batería 32.
