Description

COCHE INFANTIL  CHILD CAR
D E S C R I P C I Ó N D E S C R I P C I Ó N
OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
La presente invención se refiere a un coche infantil, de los utilizados para transportar bebés, desde recién nacidos hasta aproximadamente tres años, y en distintas posiciones corporales. The present invention relates to a children's car, of those used to transport babies, from newborns to approximately three years, and in different body positions.
El objeto de la invención es dotar a un coche infantil convencional de medios que hagan considerablemente mas fácil su movilización, concretamente con una sustancial disminución del esfuerzo físico necesario para tal movilización. The object of the invention is to provide a conventional children's car with means that make mobilization considerably easier, specifically with a substantial decrease in the physical effort necessary for such mobilization.
ANTECEDENTES DE LA INVENCIÓN Existen múltiples modelos de coches infantiles, que varían estructuralmente en función de las diferentes prestaciones requeridas, como por ejemplo de la posición corporal del bebé durante el transporte, tumbado y/o sentado, de su mayor o menor plegabilidad, de la existencia de accesorios tales como capotas plegables, cubriciones transparentes, etc. BACKGROUND OF THE INVENTION There are multiple models of children's cars, which vary structurally depending on the different benefits required, such as the baby's body position during transport, lying down and / or sitting, of its greater or lesser folding, of the existence of accessories such as folding hoods, transparent coverings, etc.
Todos ellos tienen como denominador la ineludible existencia de ruedas para su desplazamiento sobre el suelo, y de un asidero para empuje manual de los mismos. La notable complejidad estructural de los coches infantiles actuales hace que resulten relativamente pesados y que su manipulación resulte a su vez trabajosa, especialmente cuando se desplazan por las pendientes ascendentes, mas o menos inclinadas. All of them have as their denominator the unavoidable existence of wheels for their movement on the ground, and of a handle for their manual thrust. The remarkable structural complexity of today's children's cars makes them relatively heavy and that their handling is at the same time laborious, especially when they travel along the ascending slopes, more or less inclined.
Así pues, el empuje puede resultar en muchas ocasiones realmente fatigoso, pudiendo incluso llegar a generar dolores musculares en trayectos largos. Thus, the thrust can result in many times really tiring, being able to even generate muscular pains in long journeys.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
El coche infantil que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, en los diferentes aspectos comentados, constituyendo además un elemento lúdico, que hace mucho mas distraído el transporte del bebé y que supone paralelamente la práctica de un ejercicio físico, concretamente de pedaleo. The infant car that the invention proposes solves in a completely satisfactory way the problem previously exposed, in the different aspects mentioned, also constituting a playful element, which makes the transport of the baby much more distracted and that simultaneously involves the practice of a physical exercise, specifically pedaling
Para ello y de forma mas concreta el coche infantil que la invención propone parte de la estructuración básica de un coche infantil convencional en cuanto a la configuración de los medios receptores del bebé, en cuanto a su convertibilidad, etc., así como en lo que se refiere a la estructura soporte básica, pero con la particularidad de que dicha estructura se prolonga posteriormente para rematarse en un sillín, en posicionamiento adecuado para movilizar el coche como si se tratase de una bicicleta, a cuyo efecto en dicha estructura se establece también un eje pedalier, con sus correspondientes pedales, cadena de transmisión a la rueda o ruedas y cualquier otro tipo de accesorios al efecto, como por ejemplo un sistema de frenos similar al de una bicicleta, etc. El cochecito podrá tener tres o cuatro ruedas, y en cualquier caso mientras la rueda o ruedas posteriores serán las motrices, las ruedas anteriores serán las directrices, para lo que éstas últimas, conjuntamente con el cuerpo del cochecito, estarán montadas con posibilidad de giro sobre un imaginario eje vertical, con respecto al resto de la estructura, situándose el "manillar" del coche, equivalente al asa convencional en la posición clásica de ésta ultima. To do this and more specifically the children's car that the invention proposes part of the basic structuring of a conventional children's car in terms of the configuration of the receiving means of the baby, in terms of its convertibility, etc., as well as in what it refers to the basic support structure, but with the particularity that said structure is subsequently extended to finish off a saddle, in suitable positioning to mobilize the car as if it were a bicycle, for which purpose in said structure a structure is also established bottom bracket, with its corresponding pedals, chain of transmission to the wheel or wheels and any other type of accessories for this purpose, such as a brake system similar to that of a bicycle, etc. The stroller may have three or four wheels, and in any case while the rear wheel or wheels will be the driving ones, the previous wheels will be the guidelines, for which the latter, together with the body of the stroller, will be mounted with the possibility of turning on an imaginary vertical axis, with respect to the rest of the structure, placing the "handlebar" of the car, equivalent to the conventional handle in the classic position of the latter.
De acuerdo con otra de las características de la invención, se ha previsto que el sistema pedalier esté provisto de un sistema de cambio de marchas, que haga preciso un menor esfuerzo de pedaleo en los trayectos ascendentes. In accordance with another of the features of the invention, it is provided that the bottom bracket system is provided with a gearshift system, which requires less pedaling effort in the ascending paths.
Paralelamente, se ha previsto también que el coche incorpore un pequeño motor eléctrico, de corriente continua, alimentado desde una batería, que pueda movilizar el coche en determinados momentos, de forma aislada o independiente, o en combinación con el efecto del pedalier, siendo dicha batería recargable a través de la red general de suministro eléctrico, con la colaboración de su correspondiente cargador y/o aprovechando la propia energía del coche cuando se desplaza a pedales, preferentemente en los trayectos descendentes. In parallel, it is also planned that the car incorporates a small electric motor, direct current, powered from a battery, which can mobilize the car at certain times, in isolation or independently, or in combination with the effect of the bottom bracket, being said Rechargeable battery through the general power supply network, with the collaboration of its corresponding charger and / or taking advantage of the car's own energy when traveling by pedals, preferably on downward paths.
Finalmente y de acuerdo con otra de las características de la invención, se ha previsto que la estructura correspondiente al sillín y a los medios de pedaleo, sea plegable o desmontable, en orden a permitir el uso del coche infantil como un coche clásico de empuje manual, o bien para acoplar opcionalmente una base sobre la que permanecer de pie en el desplazamiento eléctrico del dispositivo, en sustitución de dichos medios de pedaleo. DESCRIPCIÓN DE LOS DIBUJOS Finally, and in accordance with another of the characteristics of the invention, it is provided that the structure corresponding to the saddle and the pedaling means, be foldable or detachable, in order to allow the use of the child car as a classic manual push car, or to optionally couple a base on which to remain standing in the electric displacement of the device, replacing said pedaling means. DESCRIPTION OF THE DRAWINGS
Para complementar la descripción que se está realizando y con objeto de ayudar a una mejor comprensión de las características del invento, de acuerdo con un ejemplo preferente de realización práctica del mismo, se acompaña como parte integrante de dicha descripción, un juego único de dibujos en donde con carácter ilustrativo y no limitativo, se ha representado esquemáticamente y en alzado lateral, un coche infantil realizado de acuerdo con el objeto de la presente invención.

REALIZACIÓN PREFERENTE DE LA INVENCIÓN PREFERRED EMBODIMENT OF THE INVENTION
A la vista de la figura reseñada puede observarse como el coche infantil que la invención propone está constituido, como es convencional, a partir de un contenedor (1) para el bebé, con cualquier estructura y configuración convencional y en cualquier caso con un asa postero- superior (2), estando dicho contenedor (1) montado a través de un eje vertical (3) sobre una estructura inferior (4) dotada de ruedas anteriores (5) y de ruedas posteriores (6), estando el eje vertical (3) asociado a la estructura correspondiente a las ruedas anteriores (5), para convertir a éstas últimas en ruedas directrices, a cuyo efecto las mismas serán direccionables a través de los correspondientes brazos (12) asociados articuladamente al asa postero- superior (2), y que se prolongan inferiormente hasta dichas ruedas. In view of the above-mentioned figure, it can be seen how the infant car that the invention proposes is constituted, as is conventional, from a container (1) for the baby, with any conventional structure and configuration and in any case with a handle - upper (2), said container (1) being mounted through a vertical axis (3) on a lower structure (4) provided with front wheels (5) and rear wheels (6), the vertical axis (3) being ) associated with the structure corresponding to the front wheels (5), to convert the latter into steering wheels, for which purpose they will be addressable through the corresponding arms (12) jointly associated with the postero-upper handle (2), and that extend inferiorly to said wheels.
La estructura (4) se proyecta primero hacia atrás para definir un punto (7) en el que situará el sillín, adecuado para que la persona (8) encargada de desplazar el coche quede convenientemente distanciada del asa postero- superior (2), que utilizará como elemento de control de dirección, y a su vez de un eje pedalier (9) que transmitirá el movimiento, mediante pedaleo, a las ruedas posteriores (6) o ruedas motrices. Como anteriormente se ha dicho, preferentemente a través de un sistema de piñones múltiples, utilizables selectivamente mediante el clásico cambio, que a su vez pueden ir acompañados de un plato doble o triple en orden a mantener las condiciones de pedaleo, mediante drástica disminución de la velocidad en rampas ascendentes. The structure (4) is first projected backwards to define a point (7) at which it will place the saddle, suitable for the person (8) in charge of moving the car to be conveniently distanced from the handle postero-superior (2), which will be used as a steering control element, and in turn of a bottom bracket (9) that will transmit the movement, by pedaling, to the rear wheels (6) or driving wheels. As previously stated, preferably through a system of multiple sprockets, selectively usable through the classic change, which in turn can be accompanied by a double or triple plate in order to maintain pedaling conditions, by drastically decreasing the speed on ascending ramps.
Como complemento a la estructura descrita, y sobre la estructura soporte (4), preferentemente en su zona inferior y correspondiente a las ruedas directrices (5), se sitúa una batería eléctrica (10) para alimentación de un pequeño motor de corriente continua (11), a través de un interruptor- acelerador establecido en el propio asidero del coche, donde además en cualquier caso se situarán la o las palancas de freno para inmovilización del coche. As a complement to the described structure, and on the support structure (4), preferably in its lower area and corresponding to the steering wheels (5), an electric battery (10) is placed to power a small DC motor (11 ), through a throttle switch established in the car's own handle, where the brake levers or immobilization levers will be placed in any case.
Como ya se ha mencionado con anterioridad, la estructura (4) del coche puede ser plegable o desmontable, en orden a que pueda escamotearse debajo del cuerpo del mismo, con lo que se posibilita la utilización de dicho coche mediante empuje manual, como en cualquier coche infantil convencional, pudiendo acoplarse opcionalmente una base sobre la que permanecer de pie, en sustitución de los medios de pedaleo, llevándose a cabo el desplazamiento a través de los medios eléctricos anteriormente descritos. As mentioned previously, the structure (4) of the car can be foldable or detachable, in order to be able to sneak under the body of the car, which makes it possible to use said car by manual thrust, as in any other Conventional children's car, optionally a base can be coupled on which to stand, replacing the pedaling means, the displacement being carried out through the electrical means described above.
Así pues y de acuerdo con lo anteriormente expuesto, el coche infantil que la invención propone, puede ser utilizado como un coche convencional, como una bicicleta, como un pequeño vehículo motorizado o con dos de estas opciones simultaneadas. Thus, and in accordance with the foregoing, the children's car proposed by the invention can be used as a conventional car, such as a bicycle, as a small motorized vehicle or with two of these options combined.
